Description

LIQUID CONTAINING BOTTLE

TECHNICAL FIELD

The invention refers to a type of liquid containing bottle, particularly suitable to any shape structures, easy to process, fast to assemble, and with good sealing effect. The invention refers to a type of smoke oil containing bottle with great sealing effect, particularly suitable to be formed in any shape structure, easy to produce, simple in structure with a safety guarantee.

BACKGROUND OF THE INVENTION

Storage and transport of a liquid product has been an important issue for manufacturers of liquid products, especially for dangerous liquid substances or readily volatile liquid materials. A liquid containing bottle with good sealing performance, simple structure and convenient appliance has always been a major pursuit of manufacturers and users of liquid products.

A smoke oil bottle with good sealing performance, simple structure and convenient appliance has always been a major pursuit of manufacturers and users of liquid products.

Liquid containing bottles are seen everywhere, such as common mineral water bottles, glue bottles, perfume bottles, and so on. Commonly used liquid containing bottle consist three parts: the bottle body, the bottle nozzle and the bottle cover or lid. Most liquid containing bottle bodies are connected with the nozzle by screw-type structures, such as glue bottles and perfume bottles listed above. There are also other bottle bodies and bottle nozzles are integrally molded and made of one piece, such as mineral water bottles. When the bottle body and the nozzle are connected by a screw-type structure, the connection joints are only able to be set in a circular structure. And it is subject to many restrictions when the producers want to make some other shapes of the liquid containing bottle. In addition, the screw-type structure is aging easily in the long-term use and leads to a leaking problem, which is of course the case that we do not want, especially when the liquid is harmful or expensive. When the screw-type structure is applied in the industrial producing and loading, it costs manual workforce to screw and connect the bottle body with nozzle. Integrally molded bottles are out of these questions, but it is restricted in producing the bottle itself, especially when a comparably small capacity liquid containing bottle is needed, requirements are hardly met by the production techniques, or the producing of the bottle container is over expensive due to complicated techniques applied. It is the expectation of producers to welcome a newly designed structure to connect the bottle body and the nozzle. Most liquid containing bottle bodies are connected with the nozzle by screwed structures or a simple snap. The screw-type structure is easily pressed and leads to a leaking problem, especially in a crowded environment. The simple snap structure is worse in sealing and when it is placed upside down, cover can be open easily. In particular, when the bottle needs to be carried or there is dangerous liquid contained, the simple snap structure cannot be applied. The screw type of structure is not only involved with damaging and aging issues, but also very inconvenient to use.

For the conventional simple structure and screw type structure, the most important point is that the open means of the liquid containing bottle of these two structures are extremely simple. When the device is placed in environment easily accessible for children, it can easily be opened by children and result in leakage of the liquid substance or dangerous eating by mistake. So, conventional liquid containing bottles, especially those placed within the reach of children are potential safety hazards.

Commonly used types of smoke oil bottles usually include two parts: bottle body and the cover, which are fixed by screw connection or plug-in structure; due to the production techniques, bottle nozzles with screw connection structure cannot be too small; but the diameter of the electronic cigarettes is generally around 0.8, so, smoke oil bottles with screw structure usually cannot go inside the electronic cigarette to fuel it up. It makes it very inconvenient for the smokers since the oil injection requires an additional auxiliary tool. There is an important issue with a direct plug-in structure because the covers are very easy to fall off and lead to leaking problem; for smokers, they need to carry the oil, and have no-fix placement for the oil bottle; without a good sealing structure, when the smoke oil bottles are upside down or squeezed, there will be oil outflow. Therefore, the use of plug-in structure certainly cannot be taken.

Commonly used types of liquid bottles are consisted of three parts: the bottle body, the bottle nozzle and the bottle cover or lid. Most liquid bottle bodies are connected with the nozzle by screw-type structure or plug in structure, which have the same problems as the two- parts bottles listed above. The bottle bodies and bottle nozzles are integrally molded or connected by screw structure, which are not recommended. When the bottle body and the nozzle are connected by a screw-type structure, the connection joints are only able to be set in a circular structure. And it is subject to many restrictions when the producers want to make some other shapes of the liquid bottle. In addition, the screw-type structure is aging easily in the long-term use and leads to a leaking problem, which is of course the case that we do not want, especially when the liquid is harmful or expensive. When the screw-type structure is applied in the industrial producing and loading, it costs manual workforce to screw and connect the bottle body with nozzle. Integrally molded bottles are out of these questions, but it is restricted in producing the bottle itself, especially when a comparably small capacity liquid bottle is needed, requirements are hardly met by the producing techniques, or the producing of the bottle container is over expensive due to complicated techniques applied. It is the expectation of producers to welcome a newly designed structure to connect the bottle body and the nozzle.

No matter the screw-type structure or the plug in structure, they have one thing in common: its open approach is very simple, and even a child can easily open it. The smokers usually place it in the readily available position at home, so children can easily get to it. With many eat-by-mistake incidents frequently happening, we should be aware that this kind of smoke oil bottle there is a certainly security risk for children. Therefore, whether or smokers or producers are hoping to design a new smoke oil bottle to overcome the above drawbacks.

Preferably, this present invention provides one liquid containing device and this device includes an upper cover, a lower cover and a bottle body. The lower cover is located between the upper cover and the bottle body with a retractable fixed connection between the cover and lower cover. The inner wall of the upper cover is provided with three snap structures and two of which are disposed opposite to each with the third one located in between. When the upper cover and lower cover are engaged, releasing them need to apply three forces. These three force need to urge the positions corresponding to the three snap structure, wherein the direction of two forces acting on the urging of the two opposite snap structures is perpendicular to the direction of the third force applied . Preferably, the upper cover and the bottle body can be made from PET, PVC, PE, PP or PS materials.

Compared with the current technology, this invention is a liquid containing bottle designed in three sessions, and can apply to any shape by adjusting the structure of the invention. Due to the separated sessions of the liquid containing bottle, it not only simplifies the model structure of the liquid containing bottle, but also making the production techniques of the liquid containing bottle easier. Further, manufacturers can standardize the parameters of the top end of bottle body and the bottom end of the lower cover, so that the bottle bodies and lower covers can be snapped together no matter what the bottle shapes are, thus to enhance the versatility of bottle bodies and lower covers in various types and simplify the production process. In industrial production, liquid will be firstly injected into the bottle body, then user can gently press down the cover to seal the bottle body fixed to the lower cover. It is easy and simple. It takes about 8 seconds to assemble a liquid into the bottle under current technology, but this invention disclosed takes about only 2 seconds to do so, which greatly reduces the time concerned and saves labor costs. The top end of bottle body and the bottom end of the lower cover are structured to match each other; especially one liquid barrier strip is set to provide very good sealing effect. The hook structure between the fix structure on the lower cover and the bottle nozzle forms the first snap structure and cleverly solves the sealing problem between the bottle body and lower cover. The bottom of the bottle body is provided with groove cone structure, which is corresponding to the bottom structure of the lower cover. When the bottom part of the lower cover snaps into the groove, it forms the second snap structure. The connection parts between the bottle body and the lower cover in the first and second snap structure are of a circular arc shape and a square shape respectively. Thus, the cover and the bottle are very tightly connected. The groove snaps fix when there is any external force in a horizontal direction, and the latch hooks fix between the liquid prevention circle and the latch subjected to any force in the vertical direction. Therefore, the bottle body and the lower cover are completely stuck together, so the lower cover is not easily squeezed open so as to avoid liquid leaking which is usually happening with the existing liquid containing bottles. The bottle body and the lower cover are strongly connected and need to use force to open them, so it will prevent the child to open them easily or drink by mistake. The bottle body is designed with a frustum structure, which increases the capacity of the liquid containing bottles. In the example of a 30ml liquid containing bottle like this, it has 5% to 30% more capacity than those of liquid containing bottle in same size. Meanwhile, the invention is designed in a rectangular shape to enhance its portable and space utilization advantages. The corners of the bottle are rounded or chamfered to give a nice and comfortable touch. To summer up, this invention provides a liquid containing bottle designed to apply to any shape structures, easy to process, fast to assemble, and portable with good sealing effect (as in figures).

Compared with the current technology, this invention is a liquid containing bottle designed in three sessions, and can apply to any shape by adjusting the structure of the invention. The upper cover and lower cover matches well through the connection structure in between and furthermore, with the card strip and bayonet, the matching arc recess and groove, as well as and pourer and the groove nozzle achieves a full range of locating and sealing effect. And because the lower cover of this liquid containing bottle will not easily be pinched off in pressure, it strongly prevents the existing liquid leaking. Besides, the pourer snaps right into the nozzle groove, to knock the upper cover and the lower cover, so the covers are tightly snapped. The most important is the opening of the liquid containing bottle in engaging state needs mutually perpendicular forces acted on the upper cover, i.e., three forces acted on the upper cover, wherein a force in the direction perpendicular to the direction of the other two forces, specifically the wherein of the two forces is to correspond to the card strip and work up against the upper cover while a third force tangent to the side wall of the upper cover is applied to whereabouts of the fingerprint groove. In normal circumstances, the user needs two hands simultaneously to impose forces of three directions to open the upper cover. So that during the process of carrying the liquid containing bottle will not easily be squeezed open. Even when it is placed within the reach of children, the cover cannot be easily turned on by them thus to prevent any risks or danger. It is a good solution to the potential risks of the liquid containing bottle. This liquid containing bottle applies a square structure with portable and space utilization advantages. The outsides are rounded or chamfered to give a nice and comfortable touch. The fingerprint groove on sidewall is designed economically with comfort and convenience. In summary, the liquid containing bottle disclosed here not only shows good stability, efficient sealing effect, but also gives a security guarantee. In order to overcome the current disadvantages of the existing smoke oil bottles, this invention designs a smoke oil bottle suitable to be formed in any shape structure, easy to produce, simple in structure with a safety guarantee.

In order to make the objects, technical solutions and advantages of the invention more clearly understood, there will be descriptions in detail further more accompanying drawings and embodiment examples. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

Refer to Figs. 1 to 3, a rectangular box-shaped liquid containing bottle body 10 is used for containing a variety of liquid substances, and the liquid containing bottle 10 comprises an upper cover 11, lower cover 15 and a bottle body 17. The structures are matched between the upper cover 11, the lower cover 15 and the bottle body 17. The lower cover 15 is located between the bottle body 11 and the upper cover 17. There is a connector 13 between the upper cover 11 and lower cover 15, and the connector 13 is located at the edges of in the upper cover 11 and the lower the cover 15. The upper cover 11 and lower cover 15, through the connector 13, may be retractably connected. The cover 11 may be buckled onto the lower cover 15. The lower cover 15 and the bottle body 17 is formed respectively and connected fix when the liquid containing bottle 10 is in usage. There are inter-fitted structures between the upper cover 11 and lower cover 15 as well as the lower cover 15 and bottle body 17, so that these three parts can be synthesized into a sealed space to contain a variety of liquids without any leaking from the lower cover 15 or the upper cover 11 out of the bottle body 10.

The liquid containing bottle 10 is made of plastic material. The distance between the upper cover 11 and the bottom part of the bottle body 17 defines the height of the bottle 10. And the liquid containing bottle 10 has a length greater than the width, and its length and width referred are not set. The ratio between the length, width and height of the liquid containing bottle 10 can be (1-5): 1: (. 0 5-10) with a preferably range of 2: 1: 4. The corners of liquid containing bottle 10 are chamfered with parameters chosen available at random. The bottle 10 surface is streamline designed, elegant with a comfortable touch. The height of the bottle body 17 takes 50% to 95% of the height of the liquid containing bottles 10, preferably at 80%. The height of the lower cover 15 accounts for 10 bottles of liquid height of 10% to 50%, preferably 35%. The height of the upper cover 11 takes 5% to 45% of the height of the liquid containing bottles 10, preferably at 20%. The form of liquid containing bottle 10 is not limited to the square box-shaped body 151, and it may be in cylindrical, flat tubular, triangular prism, cube and other irregular shapes. The connector 13 between the upper cover 11 and lower cover 15 may be of other structure in fixed axis of rotation while opening or can be set independently. On the outside surface of the liquid containing bottles 10 can be curved in various designs or be sticked on by all kinds of patterns. Bottle body 17 and the lower cover 15 may be integrally molded into production.

Refer to Figure 4, the bottle body 17 is a hollow structure with the container used as the liquid storage space of liquid containing bottle 10 for containing liquid substance. Bottle body 17 includes a bottle nozzle 171, a frustum structure 173 and a cavity chamber 175.The frustum structure 173 is located between the frustum 171 and the cavity chamber 175, and these three items are integrally modeled and formed.

The cavity chamber 175 of liquid containing bottle 10 provides the primary capacity solution, which is rectangular boxed shape. 173 is a hollow frustum shaped structure, with the bottom connected integrally with the cavity chamber 175 and the top connected integrally with the bottle nozzle 171. The frustum structurel73 provides auxiliary capacity space for Bottle body 10. The shape where the cavity chamber 175 connects the frustum structure 173 is same with the shape of the bottom of 173, but former one is little bigger than the size of the latter, so that the groove 177 is made where the two parts connects, with the groove sunken in to the bottle body 17. The size of groove 177 is matched with of the size of the bottom of the lower cover 15 so 177 is the place where the lower cover 15 snaps into the bottle body 17.

Please refer to Figures 5 and 6, the bottle nozzle 171 is a hollow cylinder, and liquid can be directly injected through. On its outer wall there is a hook structure 178, which is an annular wedge-shaped structure, formed integrally on the outer wall the nozzle 171. The cross-section of this annular wedge-shaped structure is a right angle trapezoidal, and the hypotenuse of it directs toward the upper cover 11. The hook structurel78 is used to achieve a snap fix between the bottle body 17 and the lower cover 15. Between the bottle body 17 and the hook structure 178, an annular fluid barrier section 179 is set, which is integrally formed on the outer wall of the bottle nozzle 171. The section 179 is to enhance the sealing effect of the liquid containing bottle 10. Provided the bottle nozzle height 171 is H, the hook 178 is located at the 0. lH-0. 5H of the nozzle, and the liquid barrier section 179 is located at 0. 5H-0. 95H of the bottle nozzle. It acts the best sealing and snapping effect when the hook structure 178 is at 0. 25H height of the bottle nozzle together with the liquid barrier section 179 set at the height of 0. 8H of the bottle nozzle.

The material of which the bottle body 17 is made is not set here, and it may subject to different types of materials according to the nature of the contained liquids, such as PET (Polyethylene terephthalate), PE (Polyethylene), PP (Polypropylene), PVC (Polyvinyl chloride), PS (Polystyrene) and so on. PET is preferred because the transparent bottle body 17 can be directly seen to acknowledge the remaining amount of the liquid. The shape of the bottle 17 is set neither, and it could be a cylinder, cone, cube, or irregular cubes, etc. The bottle body 17 may be integrally produced with the bottle nozzle 171 and the cavity chamber 175 without the frustum structurel73.

See Figure 7, the lower cover 15 includes a one-piece box 151, a protrusionl53 and a pourer 155, and the protrusion 153 is located between 151 and 155. The cartridge body 151 is of a rectangular box with shallow inside, and on the center of its top surface forms a upwardly projecting rectangular protrusion 153 (the name of the positions are adopted according to FIG. 7 in relative definition, not absolute positions). An awl shaped pourer 155 is protruded in the center of 153, through which the liquid amount in bottle body 17 of bottle 10 is changed. The diameter of the liquid outflow pourer decreases gradually as directing from the bottle body to the lower cover. The liquid of the bottle body 17 drips through the pourer 155.

The size of the protrusion 153 is smaller than the size of the bottom of 151, which makes a box body edge 1513. And this 1513 runs surrounds the protrusion 153, and the box 151 is connected to the protrusion 153 by it. The edge of 1513 and the protrusion 153 are provided with snap structure used for connecting the upper cover 11.

Refer to Figure 8 tolO, the lower cover 15 is internally provided with a fixed contact member 1535, the fastened member 1535 is for snapping and sealing the bottle body 17 and the lower cover 15. This fastened member includes a barrier fluid ring 1536and one pair of latches 1537 in circular strip shape, which is integrally formed on the lower part of barrier liquid ring 1536. Heights of the barrier liquid ring 1536 and 1537 together are equal to the height of bottle nozzle 171, and the upper part of 171 can be just allowed into 1535. Barrier liquid ring 1536 acts as a seal, the latch 1537 as a snap action.

1536 barrier liquid ring is a hollow cylinder, which is close to the pourer 155 and formed integrally with the protrusion structure 153, The 155 is set as the center. The inner diameter of 1536 is equal to the outer diameter of 171 of the bottle body 17; and height of 1536 is less than equal to the distance length from the hook 178 to the top of bottle body 17.The pourer 171 can be accommodated into 1536 to achieve a certain length between the sealing fit, again, on the pourer of the bottle body 171 is provided with a fine convex portions of liquid barrier 179, which forms a tiny non-destructive expansion force between the pourer 171 and the liquid barrier ring 1536 to enhance the seal effect between the two.

The pair of latches 1537 are arranged symmetrically and integrally molded on the lower barrier liquid ring 1536, the same two latch structure in 1537 and are the same size and centered by 155 set. 1537 is arc strip with an outer diameter circle equals to the outer diameter of 1536 and a bigger inner diameter than 1536. From top to bottom, the latch 1537 includes a circular section with a curved convex segment 1533, an arc section 1535. The segment 1533 is located at the arc segment 1535 and the barrier liquid ring 1536. The inner diameter of the arc section 1533 is kept unchanged, and its inner diameter is larger than the inner diameter of the liquid barrier 1536. The cross-section of the protrusion 1535 is a right angle trapezoidal, with projection downwardly into the lower cover 15. The hypotenuse of the wedge protrusion towards the direction of the bottle body 17, which means the diameter of the 1535 decreases gradually toward the direction of the cover 11, and forms on the inner wall of the latches a landslide downwardly extending into the central interior of the lower cover 15 (not numbered). The smallest diameter of the arc section 1535 is greater than the inner diameter of section 1536 but less than that of sectionl533 and the maximum diameter of the hook structure 178 on bottle nozzle 1. So, together with arc segment 1533 and the 1535 section, a snapl538 with gradient is formed. 1538 snap structure corresponds to the hook structure 178 of bottle nozzle 17. The inner diameter of the arc segment 1533 is less than equal to the maximum outer diameter of the hook structure 178, and 178 slides into the snap landslide in 1538 by the curved projection of section 1535. So that by 1538 the bottle body 17 is snapped fix with the lower cover 15.

The lower cover 25 comprises a modified embodiment, and the variant embodiment of the lower cover 15 differs only in that the internal structure of the liquid barrier structure with the latch ring 2536 and the structure 2537 shown in Figure 11. This modification example of liquid barrier ring 2536 and the latch 2537 is provided separately, and ring 2536 for holding the barrier liquid ring 1536 remains unchanged. The latch 2537 is provided separately therewith the latch 2537 is independent of the barrier liquid ring 2536 and integrally with the protrusion 253 of the lower cover 25.

The material for lower cover 15 is not set, and can be made of different types of materials according to the nature of the contained liquid, such as PET (Polyethylene terephthalate), PE (Polyethylene), PP (Polypropylene), PVC (Polyvinyl chloride), PS (Polystyrene) and so on. PP material is preferred for the lower cover 15 which can be made as translucent. The outer shape of the lower cover 15 is not limited, which may be cylindrical, conical, irregularly shaped and so on. Barrier liquid ring 1536 can be placed washer inside to seal better. The number of latches in 1537 on the lower cover 15 shall not be limited, which may be a plurality, or may be a single ring. Sealing washer can be set within the grooves 177 of the bottle body 17. Refer to FIG. 12, the upper cover 11 is a rectangular cavity opening downward, which is formed integrally with a structure matching with the lower cover 15. The lower cover 15 is provided with a structure that matches the snap on upper cover 11, which is used to achieve the snap connection between 15 and 11.

The material for upper cover llis not set, and can be made of different types of materials according to the nature of the contained liquid, such as PET (Polyethylene terephthalate), PE (Polyethylene), PP (Polypropylene), PVC (Polyvinyl chloride), PS (Polystyrene) and so on. PP material is preferred for the upper cover 11 which can be made into translucent. The outer shape of the upper cover 11 is not limited, which may be cylindrical, conical, irregularly shaped and so on.

Refer to FIG. 13, the bottle body 17 are independently produced by manufacturer, the connecting member 13 is connected to the upper cover 11 and lower cover 15, and then the liquid injected into the bottle body 17, afterwards, the bottle nozzle 171 of bottle body 17can be placed into the next part of the cover structure 1535 which is fixed to coverl5 by a gently push. 1537 includes a circular section with a curved convex segment 1533, an arc section 1535. The cross section of 1535 is a right angle trapezoidal, with projection downwardly into the lower cover 15. The hypotenuse of the wedge protrusion towards the direction of the bottle body 17, which means the diameter of the 1535 decreases gradually toward the direction of the cover 11. The smallest diameter of the arc section 1535 is greater than the inner diameter of section 1536 but less than that of sectionl533 and the maximum diameter of the hook structure 178 on bottle nozzle 1. So, together with arc segment 1533 and the 1535 section, a snap 1538 with gradient is formed. 1538 snap structure corresponds to the hook structure 178 of bottle nozzle 17. The inner diameter of the arc segment 1533 is less than equal to the maximum outer diameter of the hook structure 178, and 178 slides into the snap landslide in 1538 by the curved projection of section 1535. So that by 1538 the bottle body 17 is snapped fix with the lower cover 15. It forms the first snap with the lower cover 15. And with the guidance of protrusion 153, the lower cover 15 snap into the bottom of the groove 177 to form a second snap. The second one works on the periphery of the first one and together they play the dual role. The inner diameter of 1536 is equal to the outer diameter of 171 of the bottle body 17; and height of 1536 is less than equal to the distance length from the hook 178 to the top of bottle body 17.The pourer 171 can be accommodated into 1536 to achieve a certain length between the sealing fit, again, on the pourer of the bottle body 171 is provided with a fine convex portions of liquid barrier 179, which forms a tiny non-destructive expansion force between the pourer 171 and the liquid barrier ring 1536 to enhance the seal effect between the two. The upper cover 11 and lower cover 15, by a snap engagement between the two structures, the entire liquid containing bottle 10 is assembled.

The liquid containing bottle 10 and its embodiments may be a smoke oil bottle, used as a liquid smoke or oil container. Due to the instability of the physical properties of smoke oil and the needs to make it portable, it is highly demanded that a liquid containing bottle like the bottle 10 seals strictly and acts stably. This embodiment is just to meet the claims.

Compared with the current technology, this invention is a liquid containing bottle designed in three sessions, and can apply to any shape by adjusting the structure of the invention. Due to the separated sessions of the liquid containing bottle, it not only simplifies the model structure of the liquid containing bottle, but also making the production techniques of the liquid containing bottle easier. Further, manufacturers can standardize the parameters of the top end of bottle body 17 and the bottom end of the lower cover 15, so that the bottle bodies and lower covers can be snapped together no matter what the bottle shapes are, thus to enhance the versatility of bottle bodies and lower covers in various types and simplify the production process. In industrial production, we will first inject liquid into the bottle body 17, then gently press down the cover 15 to seal the bottle bodyl7 fix to the lower cover 15, and last cover it with upper cover 11. It is easy and simple. It takes about 8 seconds to assemble a liquid into the bottle 10 under current technology, but this invention disclosed takes about only 2 seconds to do so, which greatly reduces the time concerned and saves labor costs. The top end of bottle body 17 and the bottom end of the lower cover 15 are structured to match each other; especially one liquid barrier strip 179 is set to provide very good sealing effect. The hook structure 1537 between the fix structure on the lower cover 15 and the bottle nozzle 171 forms the first snap structure 178 and cleverly solves the sealing and snapping problem between the bottle body 17 and lower cover 15. The bottom of the bottle body 17 is provided with groove cone structure 177, which is corresponding to the bottom structure of the lower cover 15. When the bottom part of the lower cover 15 snaps into the groove 177, it forms the second snap structure. The connection parts between the bottle body and the lower cover in the first and second snap structure are of a circular arc shape and a square shape respectively. Thus, the cover 15 and the bottle 17 are very tightly connected. The groove 177 and 1537 will be snapped fix when there is any external force in horizontal direction, and the latch hooksl78 fix between the liquid prevention circle 1536 and the latch 1537 when subjected to any force in the vertical direction. Therefore, the bottle body and the lower cover are completely stuck together, so the lower cover is not easily squeezed open so as to avoid liquid leaking which is usually happening with the existing liquid containing bottles. The bottle body 17 and the lower cover 15 are strongly connected and need to use force to open them, so it will prevent the child to open them easily or drink by mistake. The bottle body is designed with a frustum structure 173, which increases the capacity of the liquid containing bottles. In the example of a 30ml liquid containing bottle like this, it has 5% to 30% more capacity than those of liquid containing bottle in same size. Meanwhile, the invention is designed in a rectangular shape to enhance its portable and space utilization advantages. The corners of the bottle 10 are rounded or chamfered to give a nice and comfortable touch. To summer up, this invention liquid containing bottle 10 provides a liquid containing bottle designed to apply to any shape structures, easy to process, fast to assemble, and portable with good sealing effect.

Refer to Figure 17, the bottle body 17 is a hollow structure with cubic container used as the liquid storage space of liquid containing bottle 10 for containing liquid substance. Top of the bottle body 17 and the lower cover 15 are corresponding to each other, provided with matching snap seal structure in between, and the bottle body 17 can be securely sealed snap to the lower cover 15. The material of which the bottle body 17 is made is not set here, and it may subject to different types of materials according to the nature of the contained liquids, such as PET (Polyethylene terephthalate), PE (Polyethylene), PP (Polypropylene), PVC (Polyvinyl chloride), PS (Polystyrene) and so on. PET is preferred because the transparent bottle body 17 can be directly seen to acknowledge the remaining amount of the liquid. The shape of the bottle 17 is set neither, and it could be a cylinder, cone, cube, or irregular cubes, etc.

See Figure 18 and 19, the lower cover 15 includes a one-piece box 151, a protrusionl53 and a pourer 155, and the protrusion 153 is located between 151 and 155. The cartridge body 151 is of a rectangular box with shallow inside, and on the center of its top surface forms a upwardly projecting rectangular protrusion 153 (the name of the positions are adopted according to FIG. 20 in relative definition, not absolute positions). An awl shaped pourer 155 is protruded in the center of 153, through which the liquid amount in bottle body 17 of bottle 10 is changed. The diameter of the liquid outflow pourer decreases gradually as directing from the bottle body to the lower cover. The liquid of the bottle body 17 drips through the pourer 155.The size of the protrusionl53 is smaller than the size of the bottom of 151, which makes a box body edge 1513. And this 1513 runs surrounds the protrusion 153, and the box 151 is connected to the protrusion 153 by it. On both sides of the 1513 edge near the connector 13 are provided with two tabs 1511, which are arranged symmetrically on both sides of the protrusion 153, with the position corresponding to the minimum curvature at the side of the cartridge body 151. 1511is of rectangular strip shape with hole, which runs through the cartridge body 151 and forms snap holes. On the cartridge body 151 opposite the connecting member 13 is located with a concave portion 1515, which is located in the side edge portion of the lid 15 downward inside the lower cover 15. On the same side of the surface of 153 is formed with an arc groove 1531, which is located in the middle of side wall of 153 with the groove downwards to the protrusion 153, therefore, the side edge of 153 opposite to the arc groove 1531 is formed in a convex canopy (not numbered), the upper cover 11 is provided with a structure which can be matched across the convex canopy structure with the arc groove 1531. And this is how the upper cover and the lower cover are snapped. Inside the lower cover 15 is provided with a snap which matches and seals the bottle body 17, and it is used to seal the bottle body 17.

The material for lower cover 15 is not set, and can be made of different types of materials according to the nature of the contained liquid, such as PET (Polyethylene terephthalate), PE (Polyethylene), PP (Polypropylene), PVC (Polyvinyl chloride), PS (Polystyrene) and so on. PP material is preferred for the lower cover 15 which can be made into semi translucent. The outer shape of the lower cover 15 is not limited, which may be cylindrical, conical, irregularly shaped and so on.

Refer to FIG. 20 and 21, the upper cover 11 is a rectangular cavity opening downward, which is formed integrally with a structure matching with the lower cover 15. The upper cover 11 is with arc sidewalls, which also showed certain arc line in direction toward the upper cover 11 of the liquid containing bottle 10. This curvature matches that of the cartridge body 151 on the lower cover 15as well as the arc on sidewall of the protrusion 153. On the side of upper cover 11 is provided with an upper recess 117. The recess 117 and the lower recess 1515 set on the lower cover 15 both forms a smooth concave surface shaped like fingerprint groove (not numbered), which is corresponding to the arc groove 1531. The shape of this fingerprint groove matches the shape of a human thumb or other finger, as in this embodiment an example of a thumb instruction is listed. This fingerprint groove is designed economically, and when the cover 11 and lower cover 15 is in engaging state, the user can place the thumb on the fingerprint groove to press open the upper cover 11. The upper cover 11 includes a nozzle groove 111 within, which has a hollow cylindrical tank body. It is located inside the center of the upper cover 11, and corresponds to the position and size of the nozzle 155 of the lower cover 15. The internal structure of 111 matches the nozzle 155. When the upper cover

II and the lower cover 15 are snapped, the nozzle 155 is just received into the groove 111 and seals the two parts. The inner wall of the upper cover 11 is integrally formed with two symmetrically disposed identical configuration card strips 113, provided in the side wall 11 at its minimum curvature. The card strips structure 113 is of a rectangular card sheet structure with a wedge-shaped structure protruding barb 1131 on the end of the outer side. 1131 barb is set in external direction toward the upper cover 11 and the hypotenuse of the wedge-shaped structure is raised downwards the direction of lower cover 15. The card strip 113 is higher than the edge of the upper cover 11, and it is positioned corresponding to the bayonet 1511. The thickness of the card strip 113 is smaller than the width of bayonetl511, and the size of barb 1131 is less than equal to the size of bayonet 1511 with its position corresponding to the external side of the upper cover 11 near the 1511 bayonet. Inside the concave portion 117is provided with an arcuate recess 115, the size of which corresponds to the size of the arcuate groove 1531 on the protrusion 153 of the lower cover 15, and when the lower cover 15 and upper cover 11 are engaged, the arcuate recess 115 slots into the groove 1531 to secure the sealing effect.

In summary, when the upper cover 11 and lower cover 15 buckles, one side is fixedly connected by connector 13 with the opposite side snapped by the arc groove 1531 and arcuate recess 115; while the other two sides are connected fix by card strip 113 on upper cover and the bayonetl511 on lower cover. When the pourer 155 is accommodated in the nozzle groove 111, it forms a sealing mode with full range engaged.

The material for upper cover llis not set, and can be made of different types of materials according to the nature of the contained liquid, such as PET (Polyethylene terephthalate), PE (Polyethylene), PP (Polypropylene), PVC (Polyvinyl chloride), PS (Polystyrene) and so on. PP material is preferred for the upper cover 11 which can be made into semi translucent. The outer shape of the upper cover 11 is not limited, which may be cylindrical, conical, irregularly shaped and so on. Structure of the pourer groove

III may be designed according to the structure of pourer 155. The number, shape and the dimension of 113, 1511, aa5 and 1531are not defined, which may be one or more of any other snap fit structure. The direction of the projection of card strip barbs 1131 on 113 are not defined, which may be a direction towards the inside of the upper cover 11, with the position corresponding to edge of the lower cover near where 1511 is set. Inside the nozzle groove 111 can be set a washer or provided with protrusion structure in direction to the pourer-out way to enhance the sealing effect. It may also be provided with a sealing gasket around 1513 on edge of the box body. Refer to Figure 22, manufactures can produce the liquid containing bottle in separated sessions: the bottle body 17, the lower cover 15 and upper cover 11 connected by connector 13. Then liquid can be injected into the bottle body 17, and seal it fixed to the lower cover 15. The upper cover 11 and lower cover 15 - one surface is connected via a fixed connector 13, when press the upper cover 11 to the lower one, the pourer 155 on 15 snaps into the nozzle groove 111 on 11, while the card strips 113 on sides of 11 correspondingly slide into the bayonet 1511. Meanwhile, because the barb structure 1131 on 113 is positioned to correspond to the outer edge of 1511, moreover, the section of 1131 is wedge-shaped with its hypotenuse downwards to lower cover 15, so when the strips 113 slide into the bayonet 1511, the barb is hooked with the inner wall of the cartridge body 151 to hold the upper cover 11 and under cover 15 together. At the same time, the arcuate recess 115 provided on the inner sidewall of 117 slots into the groove 1531on the lower cover, in order to achieve the full range of sealing effect. Till now, the liquid containing bottle 10 is assembled.

See Figure 23, the user takes a thumb to press the fingerprint groovel99with a gentle upward force while using the other thumb and forefinger on both sides of the liquid containing bottle 10 with forces towards inside the upper cover. The side wall of the cover 11 toward the direction of the cover 11 is arced, and the card strips 113 and bayonet 1511 are set at the side wall convex of the lower cover 15 on its minimum curvature, so that when the external force is applied on its sidewall, the upper cover 11 produces a slight elastic deformation toward the inner direction, and at this time, the barbs 1131 on card strip 113 offsets towards the direction of the inner upper cover. When the barbs 1131 are right against 1511, the card strips 113 exits the bayonet 1511, at the same time, the arcuate section 115, under the action of external force, exits the arc groove 1531 to make the upper cover llopen. The user places the liquid containing bottle 10 upside down, and gently squeeze the bottle body 17 to have the liquid contained dripped out.

The liquid containing bottle 10 and its embodiments may be a smoke oil bottle, used as an oil or liquid smoke container. Due to the instability of the physical properties of the smoke oil and the needs to make it portable, it is highly demanded that smoke oil bottle like the bottle 10 seals strictly and acts stably. This embodiment is just to meet the claims.

Compared with the current technology, this invention is a liquid containing bottle designed in three sessions, and can apply to any shape by adjusting the structure of the invention. The upper cover 11 and lower cover 15 matches well through the connection structure 13 in between and furthermore, with the card strip 113 and bayonet 1511, the matching arc recess 115 and groove 1531, as well as and pourer 155 and the groove nozzle 111 achieves a full range of locating and sealing effect. And because the lower cover 15 of this liquid containing bottle 10 will not easily be pinched off in pressure, it strongly prevents the existing liquid leaking. Besides, the pourer 155 snaps right into the nozzle groove 111, to knock the upper cover 11 and the lower cover 15, so the covers are tightly slotted. The most important is the opening of the liquid containing bottle in engaging state needs mutually perpendicular forces acted on the upper cover 11, i.e. three forces acted on the upper cover, wherein a force in the direction perpendicular to the direction of the other two forces, specifically the wherein of the two forces is to correspond to the card strip 113 and work up against the upper cover 11 while a third force tangent to the side wall of the upper cover is applied to whereabouts of the fingerprint groove. In normal circumstances, the user needs two hands simultaneously to impose forces of three directions to open the upper cover 11. So that during the process of carrying the liquid containing bottle 10 will not easily be squeezed open. Even when it is placed within the reach of children, the cover cannot be easily turned on by them thus to prevent any risks or danger. It is a good solution to the potential risks of the liquid containing bottle 10. This liquid containing bottle 10 applies a square structure with portable and space utilization advantages. The outsides are rounded or chamfered to give a nice and comfortable touch. The fingerprint groove on sidewall is designed ergonomically with comfort and convenience. In summary, the liquid containing bottle 10 disclosed here not only shows good stability, efficient sealing effect, but also gives a security guarantee.

Refer to Figures 24 to 26, a rectangular box-shaped smoke oil bottle body 10 is used for containing a variety of liquid substances, and the smoke oil bottle 10 comprises a cover (no numbered)and a bottle body 17; the cover should be covered onto the bottle body. The cover includes an upper cover 11 and a lower cover 15. The structures are matched between the upper cover 11, the lower cover 15 and the bottle body 17. The lower cover 15 is located between the bottle body 11 and the upper cover 17. There is a connector 13 between the upper cover 11 and lower cover 15, and the connector 13 is located at the edges of in the upper cover 11 and the lower the cover 15. The upper cover 11 and lower cover 15, through the connector 13, may be retractably connected. The cover 11 may be buckled onto the lower cover 15. The lower cover 15 and the bottle body 17 is formed respectively and connected fix when the smoke oil bottle 10 is in usage. There are inter-fitted structures between the upper cover 11 and lower cover 15 as well as the lower cover 15 and bottle body 17, so that these three parts can be synthesized into a sealed space to contain a variety of liquids without any leaking from the lower cover 15 or the upper cover 11 out of the bottle body 10.

The smoke oil bottle 10 is made of plastic material. The distance between the upper cover 11 and the bottom part of the bottle body 17 defines the height of the bottle 10. And the smoke oil bottle 10 has a length greater than the width, and its length and width referred are not set. The range of the length, width and height of the smoke oil bottle 10 can be (1-5): 1: (. 0 5-10) with a preferably range of 2: 1: 4. The corners of smoke oil bottle 10 are chamfered with parameters chosen available at random. The bottle 10 surface is streamline designed, elegant with a comfortable touch. The height of the bottle body 17 takes50% to 95% of the height of the smoke oil bottles 10, preferably at 80%. The height of the lower cover 15 accounts for 10 bottles of liquid height of 10% -50%, preferably 35%. The height of the upper cover 11 takes 5% to 45% of the height of the smoke oil bottles 10, preferably at 20%. The form of smoke oil bottle 10 is not limited to the square box-shaped body 151, and it may be in cylindrical, flat tubular, triangular prism, cube and other irregular shapes. The connector 13 between the upper cover 11 and lower cover 15 may be of other structure in fixed axis of rotation while opening or can be set independently. On the outside surface of the smoke oil bottles 10 can be curved in various designs or to be sticked on by all kinds of patterns.

This fastened member includes a barrier fluid ring 1536 and one pair of latches 1537 in circular strip shape, which is integrally formed on the lower part of barrier liquid ring 1536. Heights of the barrier liquid ring 1536 and 1537 together are equal to the height of bottle nozzle 171, and the upper part of 171 can be just allowed into 1535. Barrier liquid ring 1536 acts as a seal, the latch 1537 as a snap action.

1536 barrier liquid ring is a hollow cylinder, which is close to the pourer 155 and formed integrally with the protrusion structurel53, The 155 is set as the center. The inner diameter of 1536 is equal to the outer diameter of 171 of the bottle body 17; and height of 1536 is less than equal to the distance length from the hook 178 to the top of bottle body 17.The pourer 171 can be accommodated intol536 to achieve a certain length between the sealing fit, again, on the pourer of the bottle body 171 is provided with a fine convex portions of liquid barrier 179, which forms a tiny non-destructive expansion force between the pourer 171 and the liquid barrier ringl536 to enhance the seal effect between the two.

The pair of latches 1537 are arranged symmetrically and integrally molded on the lower barrier liquid ring 1536, the same two latch structure in 1537 and are the same size and centered by 155 set. 1537 is curved strip with an outer diameter circle equals to the outer diameter of 1536 and a bigger inner diameter than 1536. From top to bottom, the latch 1537 includes a circular section with a curved convex segment 1533, a curved section 1535. The segment 1533 is located at the curved segment 1535 and the barrier liquid ring 1536.The inner diameter of the curved section 1533 is kept unchanged, and its inner diameter is larger than the inner diameter of the liquid barrier 1536. The cross-section of the protrusion 1535 is a right angle trapezoidal, with projection downwardly into the lower cover 15. The hypotenuse of the wedge protrusion towards the direction of the bottle body 17, which means the diameter of the 1535 decreases gradually toward the direction of the cover 11, and forms on the inner wall of the latches a landslide downwardly extending into the central interior of the lower cover 15 (not numbered). The smallest diameter of the curved section 1535 is greater than the inner diameter of section 1536 but less than that of sectionl533 and the maximum diameter of the hook structure 178 on bottle nozzle 1. So, together with curved segment 1533 and the 1535 section, a snap 1538with gradient is formed. 1538 snap structure corresponds to the hook structure 178 of bottle nozzle 17. The inner diameter of the curved segment 1533 is less than equal to the maximum outer diameter of the hook structure 178, and 178 slides into the snap landslide in 1538 by the curved projection of section 1535. So that by 1538the bottle body 17 is snapped fix with the lower cover 15.

Refer to Figure 11, the lower cover 25 comprises a modified embodiment, and the variant embodiment of the lower cover 15 differs only in that the internal structure of the liquid barrier structure with the latch ring 2536 and the structure 2537 shown in Figure 11. This modification example of liquid barrier ring 2536 and the latch 2537 is provided separately, and ring 2536 for holding the barrier liquid ring 1536 remains unchanged. The latch 2537 is provided separately therewith the latch 2537 is independent of the barrier liquid ring 2536 and integrally with the protrusion 253 of the lower cover 25.

The material for lower cover 15 is not set, and can be made of different types of materials according to the nature of the contained liquid, such as PET (Polyethylene terephthalate), PE (Polyethylene), PP (Polypropylene), PVC (polyvinyl chloride), PS (Polystyrene) and so on. PP material is preferred for the lower cover 15 which can be made into semi translucent. The outer shape of the lower cover 15 is not limited, which may be cylindrical, conical, irregularly shaped and so on. Barrier liquid ring 1536 can be placed washer inside to seal better. The number of latches in 1537 on the lower cover 15 shall not be limited, which may be a plurality, or may be a single ring. Sealing washer can be set within the grooves 177 of the bottle body 17. Refer to Figure 25, the upper cover 11 is a rectangular cavity opening downward, which is formed integrally with a structure matching with the lower cover 15. The upper cover 11 is with curved sidewalls, which also showed certain curved line in direction toward the upper cover 11 of the smoke oil bottle 10. This curvature matches that of the cartridge body 151 on the lower cover 15 as well as the curved on sidewall of the protrusion 153. On the side of upper cover 11 is provided with an upper recess 117. The recess 117 and the lower recess 1515 set on the lower cover 15 both forms a smooth concave surface shaped like fingerprint groove (not numbered), which is corresponding to the curved groove 1531. The shape of this fingerprint groove matches the shape of a human thumb or other finger, as in this embodiment an example of a thumb instruction is listed. This fingerprint groove is designed ergonomically, and when the cover 11 and lower cover 15 is in engaging state, the user can place the thumb on the fingerprint groove to press open the upper cover 11.

Refer to Figures 21 and 26 to 27, the upper cover 11 includes a nozzle groove 111 within, which has a hollow cylindrical tank body. It is located inside the center of the upper cover 11, and corresponds to the position and size of the nozzle 155 of the lower cover 15. The internal structure of 111 matches the nozzle 155. When the upper cover 11 and the lower cover 15 are snapped, the nozzle 155 is just received into the groove 111 and seals the two parts. The inner wall of the upper cover 11 is integrally formed with two symmetrically disposed identical configuration card strips 113, provided in the side wall 11 at its minimum curvature. The card strips structure 113 is of a rectangular card sheet structure with a wedge-shaped structure protruding barb 1131 on the end of the outer side. 1131 barb is set in external direction toward the upper cover 11 and the hypotenuse of the wedge-shaped structure is raised downwards the direction of lower cover 15. The card strip 113 is higher than the edge of the upper cover 11, and it is positioned corresponding to the bayonet 1511. The thickness of the card strip 113 is smaller than the width of bayonet 1511, and the size of barb 1131 is less than equal to the size of bayonet 1511 with its position corresponding to the external side of the upper cover 11 near the 1511 bayonet. Inside the concave portion 117is provided with a curved recess 115, the size of which corresponds to the size of the curved groove 1531 on the protrusion 153 of the lower cover 15, and when the lower cover 15 and upper cover 11 are engaged, the curved recess 115 slots into the groove 1531 to secure the sealing effect. The user applies forces on the fingerprint groove, and the curved section 115, under the action of external force, exits the curved groove 1531 to make the upper cover 11 open. In summary, when the upper cover 11 and lower cover 15 buckles, one side is fixedly connected by connector 13 with the opposite side snapped by the curved groove 1531 and curved recess 115; while the other two sides are connected fix by card strip 113 on upper cover and the bayonet 1511 on lower cover. When the pourer 155 is accommodated in the nozzle groove 111, it forms a sealing mode with full range engaged. The material for upper cover llis not set, and can be made of different types of materials according to the nature of the contained liquid, such as PET (Polyethylene terephthalate), PE (Polyethylene), PP (Polypropylene), PVC (Polyvinyl chloride), PS (Polystyrene) and so on. PP material is preferred for the upper cover 11 which can be made into semi translucent. The outer shape of the upper cover 11 is not limited, which may be cylindrical, conical, irregularly shaped and so on. Structure of the pourer groove 111 may be designed according to the structure of pourer 155. The number, shape and the dimension of 113, 1511, aa5 and 1531 are not defined, which may be one or more of any other snap fit structure. The direction of the projection of card strip barbs 1131 on 113 are not defined, which may be a direction towards the inside of the upper cover 11, with the position corresponding to edge of the lower cover near where 1511 is set. Inside the nozzle groove 111 can be set a washer or provided with protrusion structure in direction to the pourer-out way to enhance the sealing effect. It may also be provided with a sealing gasket around 1513 on edge of the box body.

Refer to FIG. 23 and 27, the bottle body 17 are independently produced by manufacturer, the connecting member 13 is connected to the upper cover 11 and lower cover 15, and then the liquid injected into the bottle body 17, afterwards, the bottle nozzle 171 of bottle body 17 can be placed into the next part of the cover structure 1535 which is fixed to cover 15 by a gently push. 1537 includes a circular section with a curved convex segment 1533, a curved section 1535. The cross section of 1535 is a right angle trapezoidal, with projection downwardly into the lower cover 15. The hypotenuse of the wedge protrusion points towards the direction of the bottle body 17, which means the diameter of the 1535 decreases gradually toward the direction of the cover 11. The smallest diameter of the curved section 1535 is greater than the inner diameter of section 1536 but less than that of sectionl533 and the maximum diameter of the hook structure 178 on bottle nozzle 1. So, together with curved segment 1533 and the 1535 section, a snap 1538 with gradient is formed. 1538 snap structure corresponds to the hook structure 178 of bottle nozzle 17. The inner diameter of the curved segment 1533 is less than equal to the maximum outer diameter of the hook structure 178, and 178 slides into the snap landslide in 1538 by the curved projection of section 1535. So that by 1538 the bottle body 17 is snapped fix with the lower cover 15. It forms the first snap with the lower cover 15. And with the guidance of protrusion 153, the lower cover 15 snap into the bottom of the groove 177 to form a second snap. The second one works on the periphery of the first one and together they play the dual role. The inner diameter of 1536 is equal to the outer diameter of 171 of the bottle body 17; and height of 1536 is less than equal to the distance length from the hook 178 to the top of bottle body 17. The pourer 171 can be accommodated into 1536 to achieve a certain length between the sealing fit, again, on the pourer of the bottle body 171 is provided with a fine convex portions of liquid barrier 179, which forms a tiny non-destructive expansion force between the pourer 171 and the liquid barrier ring 1536 to enhance the seal effect between the two. The upper cover 11 and lower cover 15 - one surface is connected via a fixed connector 13, when press the upper cover 11 to the lower one, the pourer 155 on 15 snaps into the nozzle groove 111 on 11, while the card strips 113 on sides of 11 correspondingly slide into the bayonet 1511. Meanwhile, because the barb structure 1131 on 113 is positioned to correspond to the outer edge of 1511, moreover, the section of 1131 is wedge-shaped with its hypotenuse downwards to lower cover 15, so when the strips 113 slide into the bayonet 1511, the barb of is hooked with the inner wall of the cartridge body 151 to hold the upper cover 11 and under cover 15 together. At the same time, the curved recess 115 provided on the inner sidewall of 117 slots into the groove 1531on the lower cover, in order to achieve the full range of sealing effect. Till now, the smoke oil bottle 10 is assembled. See Figure 40, the user takes a thumb to press the fingerprint groove 199 with a gentle upward force while using the other thumb and forefinger on both sides of the smoke oil bottle 10 with forces towards inside the upper cover. The side wall of the cover 11 toward the direction of the cover 11 is curved, and the card strips 113 and bayonet 1511 are set at the side wall convex of the lower cover 15 on its minimum curvature, so that when the external force is applied on its sidewall, the upper cover 11 produces a slight elastic deformation toward the inner direction, and at this time, the barbs 1131 on card strip 113 offsets towards the direction of the inner upper cover. When the barbs 1131 are right against 1511, the card strips 113 exits the bayonet 1511, at the same time, the curved section 115, under the action of external force, exits the curved groove 1531 to make the upper cover llopen. The user places the smoke oil bottle 10 upside down, and gently squeeze the bottle body 17 to have the liquid contained dripped out. Compared with the current technology, this invention is a liquid smoke oil bottle 10 designed in three sessions, and can apply to any shape by adjusting the structure of the invention. Due to the separated sessions of the smoke oil bottle, it not only simplifies the model structure of the liquid bottle, but also making the producing techniques of it easier. Further, manufacturers can standardize the parameters of the top end of bottle body 17 and the bottom end of the lower cover 15, so that the bottle bodies and lower covers can be snapped together no matter what the bottle shapes are, thus to enhance the versatility of bottle bodies 17 and lower covers 15 in various types and simplify the production process. In industrial production, liquid will be firstly injected into the bottle body 17, then user can gently press down the cover to seal the bottle body 17 fixed to the lower cover 15. It is easy and simple. It takes about 8 seconds to assemble a liquid into the bottle under current technology, but this invention disclosed takes about only 2 seconds to do so, which greatly reduces the time concerned and saves labor costs. The top end of bottle body 17 and the bottom end of the lower cover 15 are structured to match each other; especially one liquid barrier strip 179 and barrier liquid rings 1536 are set to provide very good sealing effect. The fix latch structure 1537 on the lower cover 15 and the hook structure 178 on bottle nozzle 171 are matched as a first snap structure between the bottle body 17 and the lower cover 15; when the groove 1538 on the latches 1537 work with 178 and create a snap structure, the hook structure 178 is fixed to the curved section 1535 between the liquid barrier ringsl536 and the latches 1537 in the vertical direction; while the hook is held by the two latches 1537 in the horizontal direction, so the bottle 17 is firmly connected to the lower cover 15, and they forms a strictly sealing structure. The bottle bodyl7 is designed with a frustum structure 173, which increases the capacity of the liquid bottles. In the example of a 30ml liquid bottle like this, it has 5% to 30% more capacity than those of liquid bottle in same size. For example of a 30ml liquid bottle like this bottle 10, it has 5% to 30% more capacity than those of liquid bottle in same size. The frustum 173is provided with groove structure 177, which his corresponding to the bottom structure of the lower cover 15, which is to form a second snap structure between bottle body 17 and the lower cover 15.The upper cover and lower cover matches well through the connection structure in between and furthermore, with the card stripll3 and bayonet 1511, the matching curved recessll5 and groove 1531, as well as and pourer 155 and the groove nozzle 111 achieves a full range of locating and sealing effect. The opening of the bottle in engaging state needs mutually perpendicular forces acted on the upper cover 11, i.e., three forces acted on the upper cover, wherein a force in the direction perpendicular to the direction of the other two forces, specifically the wherein of the two forces is to correspond to the card stripll3 and work up against the upper coverll while a third force tangent to the side wall of the upper cover llis applied to whereabouts of the fingerprint groove. So that during the process of carrying the smoke oil bottle will not easily be squeezed open. Even when it is placed within the reach of children, the cover 15 cannot be easily turned on by them thus to prevent any risks or danger. It is a good solution to the potential risks of the smoke oil bottle. This smoke oil bottle applies a square structure with portable and space utilization advantages. The outsides are rounded or chamfered to give a nice and comfortable touch. The fingerprint groove on sidewall is design ergonomically to give a comfort and convenience touch. In summary, the smoke oil bottle 10 disclosed here not only shows good stability, efficient sealing effect, but also gives a security guarantee.

The description listed above is a preferred embodiment, and this invention is just limited as so. Any modification within the principles, equivalent replacement and improvement should be covered within the copyright and protection scope of this invention.
