Description

Non-refillable and anti-counterfeit closures for bottles or containers

technical field

The present invention relates to a non-refillable closure for a bottle or container containing a liquid, such as an alcoholic beverage, where there is a need for a counterfeit-resistant type of closure, and a non-refillable construction that allows pouring from the inside of the bottle Liquid comes out, but liquid cannot be filled into the bottle.

Background technique

In the current market, there are various non-refillable and anti-counterfeit occlusion devices, or samples that combine the above two features, in which there are certain deficiencies that do not guarantee to the consumer that they fulfill their purpose, namely, the bottle Not to be refilled, or not adulterated from the original liquid. The object of the present invention is to overcome the drawbacks of the prior art described above and to provide a non-refillable closure for bottles which meets these requirements, having a counterfeit-resistant screw top cap whose construction effectively prevents refilling, Furthermore, the closure cannot be removed from the neck of the bottle without destroying its structure, or without giving an indication of theft.

The object of the present invention is achieved by the construction of a non-refillable closure which ensures that, once inserted into the mouth or neck of a bottle, it cannot be removed without removing the lower anti-theft display ring located on the threaded top cap. The closure, the aforementioned anti-theft display ring, is divided into two parts so that it can be confirmed that the top cap has been unscrewed before this and has been stolen. The retaining sleeve on the outside of the neck of the bottle is a different color, which makes the lack of a tamper-evident display ring more apparent.

Another object of the present invention is to ensure the formation of an airtight structure, a two-part roof utilizing two concentric rings, and a downwardly extending rod in the central portion of the inner surface of the top wall to form a double seal.

The combination of upper valve, lower valve, glass bulb, intermediate washer or gasket and spout design is very important and necessary to make an effective non-refillable closure.

Finally, in order to ensure that the obturator cannot be removed from the bottle without destroying the closure, inside the holding sleeve there is a horizontal fixing structure, which is located below the band or the circular cavity in the neck of the bottle. To avoid removal of the retaining sleeve, the retaining sleeve may be molded in a plastic resin, which has a softening temperature above 100°C. Furthermore, since an additional measure is provided to prevent dismantling of the holding sleeve, special temperature-sensitive chemicals can be applied to the fixing tube. Therefore, if, in order to attempt to remove the occlusive device, the fixation tube is placed in heated ambient conditions, under such ambient conditions, the aforementioned chemicals activate, giving a visible indicator mark.

Contents of the invention

The present invention relates to a closure device of the specially constructed, counterfeit-proof and non-refillable type for containers containing liquids.

The non-refill feature is achieved by the structure comprising the gasket/intermediate ring, lower and upper valves, glass bulb between the two valves, pour spout and retaining sleeve. This structure allows liquid to flow in one direction, but prevents liquid from flowing in the opposite direction. When the liquid is poured by inverting the container, the valve disengages from the valve seat position, and when an attempt is made to refill the bottle, the access to the interior of the bottle is blocked as the valve sits on the valve seat with the gasket.

The present invention is characterized by a non-refillable structure comprising a lower valve at the lower portion of the intermediate ring, a glass bulb located inside the lower valve, a retainer that cooperates with the lower valve and holds the glass bulb between the upper valve and the lower valve. position of the upper valve. The combination of these two valves is very effective in preventing liquid from entering the bottle, while allowing liquid to flow out when the bottle is tilted to pour the contents, the valve and glass bulb are displaced. When positioned along the vertical direction, due to the gravity exerted by the glass ball on the lower valve, the lower valve is seated on the annular valve seat of the middle annular member. A series of small vertically disposed segments or ribs on the lower portion of the intermediate ring maintains the lower valve in a central position and inhibits its displacement along the vertical axis. Thus, to pour liquid from the bottle, the liquid impinges on the central cavity on the lower surface of the lower valve, displacing the lower valve, thereby displacing the lower valve, and, displacing the upper valve from its position, allowing the liquid to flow through .

The non-refillable structure has an upper valve located on the upper part of the intermediate ring, whose function is to block access to the interior of the bottle through the valve seat. When the container is inverted to pour out the liquid, the upper valve separates from the middle ring due to the glass ball hitting the lower surface inside the upper valve.

Below the lower surface of the upper valve is a series of depending teeth that cooperate with another set of upwardly extending teeth on the lower valve, the purpose of which is that if the upper valve is turned, the lower valve will be turned accordingly. This reason is because when the threaded cap is unscrewed, it will affect the contact between the valve seats of the upper valve, the lower valve, the intermediate ring and the upper and lower valves, and the valve can rotate. Sticking between the seats will prevent movement between the valves, especially if the liquid contains sugar, or some other material that tends to stick to the seat surfaces.

The non-refillable closure has two locking surfaces to prevent outward flow of liquid when the closure is threaded in place on the container. One of the blocking surfaces is formed by one or more depending concentric rings which enter the upper cavity of the pouring spout to block the outlet. The other locking surface is formed by the central bar of the inner surface of the top wall of the inner cap of the closure. Enter the installation position through the screw blocking device, so that the rod enters the pouring spout through the central cavity, and the lower end of the rod is formed into a cross structure, which enters the conical cavity of the upper valve. The rod pushes the upper valve against the center ring and the valve seat, thereby blocking liquid from flowing out through the outlet of the center ring. Another purpose of this lever is to cause the valve to turn when the closure is unscrewed, since the cross piece enters the conical cavity of the upper valve, causing the valve to turn with the threaded cap.

The threaded cap or closure has a tamper-evident band or ring located under its outer depending wall, which has a series of inwardly extending angled teeth which function to allow the top to be installed without damaging the top. At the same time, when the top cover is screwed away, the ring member is prohibited from rotating. This is due to the teeth being positioned in abutting contact with a series of angled teeth on the lower outer surface of the intermediate ring. Said ring is connected to the body of the occlusion device by means of a series of horizontal sections or bridges which can destroy the integrity of the ring with the outer cover, and when the outer cover is unscrewed and the ring does not rotate, the ring is held tear down. This anti-theft indicator ring may be provided with two vertical cuts, 180° apart, which are broken when the ring is detached from the body of the obturator and split into two parts.

On top of the outer cap is the outside of the threaded closure which holds the inner cap in place by means of horizontal ribs on the inside of the outer cap. These ribs interlock with horizontal ribs on the outside of the inner cover. The design of the inner cover has a rounded, grooved surface that mates with a grooved surface on the inner surface of the outer cover.

Due to the requirement that the closure or top is always screwed into the correct position relative to the spout, two projections at 180° apart are provided on the upper surface of the spout, which correspond to two similar notches located above the inner surface of the top match. The result is a protrusion that puts the teeth of the anti-theft display ring in the correct position so that when the top is screwed in for the first time, it sits between the teeth of the pour spout, so that when the top of the threaded fit closure is unscrewed for the first time, Causes the horizontal portion or bridge connecting the anti-theft display ring to the top body to break.

The retaining sleeve forms the lower outer cylindrical part of the obturator and is mounted on the lower part of the pouring spout by means of snap-fitting, adhesive bonding or ultrasonic welding.

On the inner cylindrical surface of the retaining sleeve is a series of angled horizontal ribs or fixtures that allow the sleeve to slide over the neck of the bottle and are positioned under a circular band extending outward from the neck so that when someone tries to remove the It prevents it from removing or moving the sleeve when removing it from the bottle. There are also a series of vertically arranged ribs on the inner cylindrical surface of the sleeve. These ribs are located in the grooves or vertically arranged grooves on the neck of the bottle. They contact and cooperate with each other to prevent the sleeve from turn.

Specific embodiments of the invention

With reference to accompanying drawing 1, can see the installation position of each part among the present invention: close outer cover "A"; Inner cover "B"; Pour out spout "C"; "; glass bulb "F"; lower valve "G"; retaining sleeve "H"; bottle or container neck "I".

In Figure 2b, a closure "A" can be seen which has a vertical wall 1 with a series of grooves or ribs 3 on its outer surface to facilitate gripping by hand Or turn closed cover "A". On the inner upper part 2 of the vertical wall 1, a series of ribs arranged in the vertical direction are arranged so as to engage with the vertical ribs 14 on the inner cap "B" of the screw closure, and the vertical ribs 14 are located on the vertical The outer upper portion of the wall 6, as shown in Figure 3b, is intended to provide cooperating rotation between the closed outer cap "A" and the threaded inner cap "B".

A series of horizontal beads or ribs 4 are provided in the middle of the inner side of the vertical wall 1 of the outer closure "A" to cooperate with similar grooves 7 on the vertical wall 6 of the inner threaded closure "B" for the purpose of A tight seal is maintained between the outer closure cap "A" and the inner threaded closure cap "B". Closure outer cap "A" has a horizontally disposed cylindrical surface 18 which when in contact with horizontal cylindrical surface 23 of threaded closure inner cap "B" B" positioning.

When the closure outer lid "A" is installed on said closure inner lid "B", the end horizontal annular portion 5 of the vertical wall 1 of the closure outer lid "A" is connected with the anti-theft of the threaded closure inner lid "B". The upper contact fit of ring 9 is shown. The upper end of the vertical wall 6 of the inner threaded closure "B" is angled 16 to facilitate installation in the outer closure "A".

The threaded inner cap "B" has a vertical wall 6, the inner surface of which has at least one thread 8 which enables the threaded inner cap "B" to form a thread 31 on the pouring spout "C" shown in Figure 4a Thread fit.

An anti-theft display ring 9 is provided on the lower part of the threaded inner cap "B", and the anti-theft display ring 9 is connected to the cover body of the threaded inner cap "B" through a plurality of spokes 19, as shown in FIG. 3a. The webs 19 are connected to the vertical wall 6 by a series of small bridges 20 which are broken when the inner lid "B" is unscrewed from the spout "C" for the first time. By means of a series of angled teeth 21 on the inner wall of the anti-theft display ring 9, the increased wall thickness 22 contacts and cooperates with a series of angled teeth 24 on the pouring spout "C" in the opposite direction to complete the above operation. . When the threaded inner cap "B" is unscrewed, the angle of these teeth can prevent the anti-theft display ring 9 from rotating. The non-rotation of the anti-theft display ring 9 in the counterclockwise direction results in the destruction of the small bridge 20, which separates the anti-theft display ring 9 from the vertical wall 6 and can be divided into two or more parts.

Due to the need to correctly position the angled teeth 21 of the threaded inner cap "B" relative to the angled teeth 24 of the pouring spout "C", a thread, or stop, is provided on the inside upper portion of the threaded inner cap "B" 15. When the threaded inner cap "B" is positioned on the spout "C", the stopper 15 restricts the threaded inner cap "B" from rotating. Utilizing the connection between the threaded stopper 15 and the angled blocking element 37 on the pouring spout, an opening-blocking structure is formed, and when the closure is threadedly engaged with the pouring spout "C", the teeth 21 and 24 are prevented. overlap each other. The closure part that is fully threaded with the spout "C" constitutes a state where the pawl cooperates with the pawl. Under the condition that the anti-theft display ring 9 is not removed, the closure part "B" cannot be screwed from the spout "C" release. Thread stop 15 prevents further rotation of the closure on the spout and forces pawl teeth 21 and 24 into position. Thus, the threaded stop 15 and the element 37 are in a position that ensures the pawl teeth when the closure is fully on the pouring spout.

As shown in Figure 3b, on the inner surface of the top wall 17 of the threaded inner cap "B", it can be seen that there is an annular downwardly hanging sealing ring 12, and its end has one or more sealing ribs 13, when Said sealing ribs 13 form an airtight seal when they are mounted in one or more annular cavities 36 on a spout "C" as shown in Figure 4a. An annular cavity is formed by the sealing ring 12 and the circular horizontal wall 34 and blocks the outlet 36 of the spout "C" after the closure has been screwed on. Moreover, as shown in the figure, inside the top wall 17 of the threaded inner cap "B" there is a circular pendulous rod 10 with a cross body 11 at its end, which passes through a central circular hole 41, Access the inside of the spout "C". Thereby, the cross body 11 is allowed to enter the upper conical cavity 65 of the cylinder 66 of the upper valve "E" as shown in Fig. 6b. Vertical key 68 causes valve "E" to rotate when threaded inner cap "B" is rotated away. Since the circular cavity 65 has tapered vertical walls, the pressure exerted on the cross body 11 of the threaded inner cap "B" also helps the upper valve "E" to rotate and lift.

Referring again to Figures 4a and 4b, the circular horizontal top wall 40 of the spout "C" has a depending annular wall 42, the purpose of which is to guide the vertical displacement of the upper valve "E" in Figure 6a, thereby limiting the upper valve Lateral movement of upwardly extending cylinder 66 in "E". When the upper circular surface 66 is in contact with the surface of the spout "C" or the circular wall 40, vertical movement of the upper valve "E" is restricted.

The surface or pouring lip 38 of the spout "C" has a curved or beveled portion 39 on the inner wall, the purpose of which, when pouring the liquid, is to cut off the flow of the liquid and prevent the liquid from leaking down or into the Pour out the outside of mouth "C".

In order to fix the downwardly depending annular wall 42 of the spout "C", a series of vertical webs 33 are provided which are in contact with the interior of the depending wall 32 . On the inner surface of the depending wall 32 of the pouring spout "C" there is provided an annular recess 30 received in the horizontal flange of the side wall 46 of the intermediate ring "D" as shown in Figure 5a , to prevent the spout "C" and the ring "D" from separating from each other when these two elements are assembled together.

When the annular base 29 of the spout "C" is in contact with the vertical rib 48 of the intermediate ring "D", the intermediate ring "D" is limited by the annular base 29 of the spout "C". Movement in the vertical direction. The circular base surface 27 of the spout "C" limits the movement of the middle ring "D" towards the inside of the spout "C" by interfacing with the downwardly depending annular flange 51 of the middle ring "D". The annular base 25 of the spout "C" has inclined side walls 26 which are interconnected with the circular surface 88 and ring 87 of the holding sleeve "H" by means of adhesive and ultrasonic welding.

Referring to the intermediate ring "D" shown in Figures 5a and 5b, the upper cylindrical side wall 46 of said intermediate ring "D" has a first set of vertically disposed ribs 45 which guide Upper valve "E" moves vertically and allows liquid to flow between the two. The upper end edges of these vertically disposed ribs 45 have a downwardly inclined angle 43 which facilitates guiding the upper valve "E" into the interior of the intermediate ring "D". Said intermediate ring "D" is also provided with an internally located annular lip 49 which serves as a seat for the upper valve "E" when the annular lip 49 is in contact with the annular seat of the upper valve "E". 69 contact each other, the valve seat 69 of the upper valve "E" is received in the annular lip 49 of the intermediate ring "D" under the vertical downward pressure of the rod 10 of the threaded inner cap "B" , forming an effective hermetic seal. The aforementioned pressure may also define the dimensions of the valve seat, which may bend during molding or insertion of the intermediate ring "D" into the wall of the bottle "I". The horizontal circular surface 53 of the intermediate ring "D" has at least one circular protrusion 52 between which, when said circular protrusion 52 is in contact with the horizontal circular surface 100 of the bottle "I", Helps form an effective hermetic seal, as shown in Figure 1 and Figure 9a.

The depending ring 51 of the intermediate ring "D" is angled inwardly for the purpose of facilitating assembly when the intermediate ring "D" is inserted into the sleeve "H". The outer wall of the downwardly depending annular wall 54 of the intermediate ring "D" has a series of horizontally disposed flanges 56 which form an airtight seal when in contact with the inner wall 103 of the bottle "I".

The middle ring "D" has a second set of vertically disposed ribs 55 which guide the vertical movement of the lower valve "G" and allow liquid to flow between the vertically disposed ribs 55. Flow between part and lower valve "G". The upper end of the vertical rib 55 is angled 50 to facilitate entry of the lower valve "G" into the interior of the intermediate ring "D", as shown in Figure 7a.

When the vertical inner surfaces 57 and 60 of the intermediate ring "D" and the vertical surfaces 78 and 81 of the second lower valve "G" contact each other, the intermediate ring "D" and the lower valve "G" have a transverse seal. When the horizontal valve seats 49 and 59 of the middle ring "D" are in contact with the corresponding horizontal valve seats 69 and 83 of the upper valve "E" and the lower valve "G", in the middle ring "D", the first valve The seal between "E" and the second valve "G" is also very effective.

During tilting of the bottle "I", when the upper valve "E" and the lower valve "G" are displaced, liquid flows from the inside of the bottle "I" through the orifice 73 of the middle ring "D". The liquid passes through the orifice 36 in the middle ring "D" through the space between the vertical ribs 55 and 45 and the pouring spout "C".

The upper valve "E" shown in Figures 6a and 6b has an annular surface 67 which guides the displacement of the upper valve "E" in the vertical direction by means of vertical ribs 45 on the upper side wall 46 of the intermediate ring "D". The upper side wall 46 of the intermediate ring "D" has an outer diameter nearly equal to the inner diameter of the side wall 32 of the spout "C", forming an effective airtight seal when the two elements are assembled together.

The annular surface 67 of the upper valve "E" has a structure to guide the valve "E", when the tapered surface 69 contacts the top corner of the inner ring 49 of the middle ring "D", between the upper valve "E" and the middle ring "D". An effective seal is formed between ring members "D".

On the depending portion of the upper valve "E" there is provided a series of downwardly depending teeth 71, the purpose of which is to limit the lateral movement of the glass bulb "F" shown in FIG. These teeth 71 intermesh with a series of upwardly extending teeth on the lower valve "G", and when the threaded inner cap "B" is rotated loose, the teeth make the upper valve "E" and the lower valve "E" G" turn. When the cross body 11 enters the tapered conical cavity 65 with a key, and the teeth 71 and 76 arranged in the vertical direction engage with each other, resulting in the upper valve "E", the lower valve "G" and the middle ring member The rotation of the upper valve "E" is transmitted to the lower valve "G" when the possible bond between the seats of "D" is broken.

The inner lower portion 72 of the upper valve "E" has a hemispherical structure to accommodate the glass ball "F" inside the hemispherical structure when the upper valve "E" is displaced while the liquid is being poured from the inside of the bottle "I".

The teeth 76 of the lower valve "G" shown in Figures 7a and 7b have transverse walls 75 which oppose The teeth 71 of the upper valve "E" are arranged next to each other. The lower portion 74 of said tooth 76 has a circular shape. The glass ball "F" is lodged between these vertical parts, limiting the lateral movement of the glass ball "F". Since the teeth 76 protrude above the lower valve "G" with radial surfaces 77, the glass bulb "F" is centered by these radial surfaces 77.

The upper body portion of the lower valve "G" consists of a cylindrical body 79 having a vertical outer surface 78 which, when in mutual contact with the vertical ribs 55 of the intermediate ring "D", Surface 78 limits lateral movement of the lower valve. The lower portion of the cylindrical portion 79 of the lower valve "G" is provided with a horizontal valve seat 83 which, when in contact with the valve seat 59 of the intermediate ring "D", is exerted by the gravity of the glass ball "F". The pressure on the lower valve "G" creates an effective seal between the lower valve "G" and the intermediate ring "D". The lower portion of the lower valve "G" is formed by a vertical cylinder 82 having a diameter smaller than that of the cylinder 79, and the outer surface 81 of the lower valve is in contact with the vertical cylindrical shape of the intermediate ring "D". When the surfaces 57 are in close contact, a transverse seal is formed. The lowermost portion of the vertical cylinder 82 of the lower valve "G" has a horizontal cylindrical surface 83 which contacts the rib 62 so as to keep the horizontal cylindrical surface 83 centrally located in the middle ring "D".

The retaining sleeve "H" shown in Figures 8a and 8b has a side wall 89 inside which is provided a series of fixtures 91 formed by inwardly sloping angled surfaces 92 and 93 and towards The outer sloped angled surface 90 constitutes. A retaining sleeve "H" retains the entire obturator within the bottle "I", as shown in Figure 1 . The spout "C", center ring "D", upper valve "E" and lower valve "G" are held in place by the upper portion 88 of the side wall of the sleeve "H". When the sleeve "H" is secured to the bottle "I", the surfaces 92 and 93 slide over the surface of the bottle "I", easily positioning the fixture 91 below the horizontal circular surface 104 of the bottle "I", As shown in Figure 9a. Since the holder 91 has a diameter slightly larger than the diameter of the side wall 105 of the bottle "I", and smaller than the diameter of the side wall 102, movement of the sleeve "H" in the vertical direction is prevented. The surface 90 of the sleeve "H" is in close contact with the angled surface 104 of the bottle "I", once the sleeve "H" is installed and positioned on the bottle "I", the sleeve "H" and all non- The internal parts of the refill closure element move.

In order to prevent rotational movement of the sleeve "H" relative to the bottle "I", a series of vertically aligned ribs 94 and 95 are provided on the inner wall 89 of the sleeve "H", these ribs 94 and 95 are positioned at Between the vertically disposed portions 107 of the bottle "I", they are aligned with each other, preventing the cylindrical sleeve "H" from rotating. The lower ends of the vertically disposed ribs 94 and 95 have angled portions 96 which guide the vertical ribs 94 and 95 and position them between the vertical ribs 107 of the bottle "I".

In order to initially position the sleeve "H" accurately on the bottle "I", small vertically extending ribs 97 are provided. The lower end of the side wall 89 is provided with an angled portion 98 so that when the sleeve “H” is positioned on the bottle “I”, said angled portion 98 is held against the angled surface 108 of the neck of the bottle “I”. superior. To facilitate positioning of the sleeve "H" on the neck of the bottle "I", at the end of the upper cylindrical portion 106 there are two angled surfaces 99 and 101.

When the container "I" is slightly tilted, a problem may arise that the lower valve "G" may disengage from the middle ring "D" and the bottle "I" may be refilled with its contents. To prevent this problem, another design of the lower valve 121 is depicted, as shown in FIG. 10 . The intermediate ring 120 has an annular valve seat 125 which interengages with an annular valve seat 126 of the lower valve. As in the first embodiment, when the lower valve and the intermediate ring are aligned with each other, as shown in Figure 1, fluid cannot flow into the container through the lower valve because the only passage is through the adjacent valve seat. Pressure from the glass bulb or the like in the interior 127 of the lower valve 121 forces the valve seats closer to each other thereby forming a tight seal. Additionally, when the container is turned upside down or tilted, the lower valve 121 moves upward and allows liquid to flow through the aperture 128 . In this embodiment, the lower valve has a straight stem 122 extending downwardly from its lower surface. The straight rod 122 extends downwardly through the lower portion of the intermediate ring 120 and through a hole 124 in the bottom wall 123 of the intermediate ring 120 . The central stem 122 ensures that the lower valve 121 is in a suitable stable position and is centered on the valve seat 125 so that the valve 121 does not shift when the bottle or non-refill closure is tilted at an angle.

In order for the user of the package to determine the proper workload and displacement of the valve in the vertical direction, an additional embodiment is depicted in FIG. . The valve stem 130 extends upwards by a distance greater than that previously shown in Figure 6a. The valve stem 130 has an aperture 134 at the uppermost portion for receiving a rod member 133 extending downwardly from the inner top wall of the threaded closure cap. When the bottle is tilted so that fluid passes through the valve and exits through the flow hole 136, the upper valve moves vertically so that the valve stem 130 extends upwardly through the pouring spout 135, providing a visual indicator for the user, Now the valve 131 works normally.

In another modified design structure, in order to prevent the contents of one package from passing through the shaking closure device, so that the contents enter the other package, by using a single annular flange 142 as shown in Figure 12 The lower valve 143 can meet the above requirements. In this design, the lower valve 143 contacts the annular flange 142 on the intermediate ring 145 . The lower valve 143 has a downwardly extending portion 140, the downwardly extending portion 140 has a lowermost side wall, and has an outwardly extending protrusion 144 on the side wall, the side wall is a closed structure, However, the downwardly extending wall 146 of the intermediate ring is not contacted. Thus, between the lower valve 143 and the intermediate ring 141, there is only a single point of contact at the flange 142, allowing the movement of the lower valve to be unimpeded. Also, the lower valve 143 is flexible so as to provide an adequate seal around the bead or flange 142 . Also, the structure of the saddle-shaped flange 142 due to the out-of-round shape of the container hole can be overcome. The horizontal distance between the circular wall 146 and the protrusion 144 can be small so that a slight seal can be formed between these two surfaces without providing a significant point of contact. Also, the protrusion 144 can exit along the downwardly extending wall 146 of the intermediate ring member, as shown in another state on the right side in FIG. 12 . The distance between the lower annular wall 141a shown in Figure 12 and the lowermost annular surface 140a similar to the valve 140 (on the left) constitutes a check valve so that before a large amount of the contents can pass through the valve , the valve must move a predetermined distance in the vertical direction. This distance can be changed according to the height of the side wall 147, so that before the liquid flows out, the lower valve is separated from the valve seat in the vertical direction relative to the intermediate ring 141 by a predetermined distance provided by the length of the side wall 147. This predetermined distance maximizes the effectiveness of the refill closure and prevents refilling of the container by shaking or other means.

An improved check valve may be provided on the lower valve to ensure a sufficient seal between the lower valve and the intermediate ring. On the intermediate ring 151 there is an annular stop 152 which is used in combination with a thin flexible sealing flap 153 as shown in Figures 13a and 13b. Seal flap 153 provides a first seal between intermediate ring 151 and valve 150 . As a second sealing structure, the blocking member 152 may be located on the middle annular member and extend upwards therefrom to contact the lower annular surface 155 of the valve 150 . Additionally, a downwardly extending stopper 154 may be provided on the outer edge of the annular valve 150, as shown in Figure 13b. During assembly, a stop on the intermediate ring 151 or a stop on the valve 150 limits compression of the sealing flaps 153 or helps maintain a proper seal if pressure forces liquid through the check valve.

Another issue that needs to be considered for this kind of non-refillable closure is that when the bottle cap is fully screwed on the pouring spout, the rotation stops, especially when it is necessary to consider the processing tolerances of the individual components. seal. With the embodiment shown in Fig. 14, potential leakage hazards can be eliminated.

As shown in FIG. 14 , the non-refillable closure has allowable flex features, and the top wall of the flexible inner cap 160 has the aforementioned flex features, which can be slightly bent upwards to apply pressure to the protruding upper valve 162 via the stem 161. . This upper valve 162 has a flexible annular surface 163a, as shown on the left in Figure 14, which represents the state in which the threaded cap is before downward pressure is applied. The upwardly extending wall 164a of the intermediate annular member contacts the annular surface 163a, thus causing the annular surface to flex upwardly when the screw cap 160 is moved downwardly. The annular surface 163b in the right part of Fig. 14 is shown as being a force fit with the slightly deformed intermediate ring wall 164b after the screw cap has been sufficiently tightened. Deformation of the surface 163a and the side wall 164b of the intermediate ring or the top wall 160 of the cover allows the upper valve 162 to flex, ensuring that an adequate seal is provided despite slight tolerances in the manufacturing process.

In order to provide an additional or another tamper-indicating means to the non-refill closure, the sealing means 170 may be brought into abutment against the pouring lip 172 of the pouring spout 174 . The inner seal 170 has a pull tab 171 which can be peeled off by the user in order to remove the circular sealing disc or gasket 170 . In addition, the tab 171 may be provided with a centrally located hole 173 to allow the rod of the downwardly extending screw cap to enter the upper valve 176 and exert pressure on the upper valve 176 as described in the previous embodiment. . Inner seal 170 contacts pour spout 174 along annular pour lip 172 and is bonded thereto by induction bonding or the like. Therefore, on first use, the inner seal 170 must be removed on the pouring lip 174 before dispensing the contents in order to indicate the presence of a prior tamper-evident device on the inside of the container. As shown in Figure 16, in order to provide a sufficient seal between the pouring spout 181 and the screw cap 180, a bendable flange 182 is provided on the upper surface of the pouring spout 181 so that the inner top wall 183 of the screw cap and the pouring A suitable sealing structure is formed between the spouts 181 . Said flange 182 provides sufficient sealing between the pouring spout and the closure, so this easily bendable sealing structure can ensure that there is no spilled contents between the closure 180 and the pouring spout 181, and the contents will not will enter the threaded area in between. The liquid contents in this threaded area end up being distributed along the outside of the container, which is a most undesirable situation. The flange 182 may be molded in an upwardly extending position and may be bent during the assembly process, either by means of an assembly mandrel, or by screwing the closure onto the pouring spout, as shown in FIG. 16 . The force of the thread movement causes the closure to be seated on the spout, thereby exerting sufficient pressure that the flange 182 bends and a sufficient seal is formed between the spout 181 and the inner bottom surface 183 of the screw cap 180. . After unscrewing the outer cap, the flange 182 returns to its upwardly extending angular position, thereby constituting the pouring lip.

Another problem that exists in anti-theft indicating devices for non-refill closures is that in heated ambient conditions, the non-refill valve can be removed. Since the retaining sleeve, or the valve itself, is made of thermoplastic resin material, it is easily deformed by heating sufficient to allow removal of these elements from the container neck. Under normal environmental conditions, removal of the sleeve from the neck of the container causes the retaining sleeve made of thermoplastic resin material to break, thereby indicating that the container has been stolen. However, there is no anti-theft indication for the user to remove the valve from the container in the heated material condition. Another structure to prevent this phenomenon is to place heat indicating ink or other chemicals on the retaining sleeve 190, or on the outside thereof, so that if the retaining sleeve is placed in a heated environment, the appropriate Warning or other indicative markings 191, as shown in FIG. 17 . Thus, if the neck of the container is heated to a predetermined temperature, an anti-theft indication can be observed by means of a "counterfeit" written in heat-sensitive ink or other colored indication. This will alert the user that the closure has previously been stolen and its contents are not guaranteed.

Another means of preventing heating of the container, and removal of the non-refillable closure from the container, is to apply a heat resistant adhesive along the horizontal surface 53 of the middle ring "D" shown in Figure 5a. This type of adhesive prevents removal of the intermediate ring from the bottle by immersing the non-refillable closure in hot water. After application of this adhesive, removal of the center ring will result in visible damage to the center ring, thereby providing an anti-theft indication of the contents.

An opening blocking structure will be discussed in detail below with reference to FIG. 18 , wherein the container 200 is provided with a blocking member 203 that controls the position of the ratchet 205 relative to the ratchet 202 on the container neck. As can be seen from accompanying drawing 18, the stopper 206 is directly arranged on the bottom edge of the closure 201, which directly contacts the stopper 203, so the stopper 203 does not prevent the closure from rotating, but when the stoppers 203 and 206 contact each other , to prevent the closure member 201 from continuing to rotate clockwise. Ratchets 205 and 207 are located in place between ratchets 202 on the container neck. The ratchet 205 is located on the inner surface of a tamper-indicating band 207 that ruptures when the closure 201 is removed from the container 200 for the first time. During installation of the closure, since the stoppers 203 and 206 prevent further rotation of the closure 201 on the container threads 204, providing a seal, as shown in FIGS. , and stuffed into the neck of the container 200 and the inside of the spout 39a. Such a plug seal will operate within the height of the barrier structure to ensure that the closure will also prevent the contents of the container from spreading outwards after the closure has failed to rotate further.

Accompanying drawing 19 has described in detail the sealing structure that pours out spout and bottle cap combination, opens the blocking structure, and in accompanying drawing 19a, the stopper sealing member 211 that depicts hangs down from the top wall lower side of closing member 210, and presses against The cap is attached to the side wall of the pouring spout. An alternative form of this seal is depicted in Figures 19b and 19c, wherein an inwardly extending bead 212 contacts the outer surface of the uppermost side wall of the container spout and cap combination. In Figure 19c, the outwardly extending bead 213 contacts the inner surface of the uppermost end of the side wall of the closure. These different embodiments ensure that a sufficient seal is formed between the closure and the container or pouring spout, and any possible variation in the vertical direction along the entire length is guaranteed to be effective by means of the opening blocking element.

In Figures 19d, 19e, 19f, 19g, other opening barrier variants are depicted. Details of the projection 214 provided on the outside of the container neck, or on the non-refilling spout assembly below the lower edge of the closure 210, are depicted in detail in Figure 19d. A cooperating depending tab 215 is provided on the lower edge of the closure 210 to contact an opening stop tab on the container or non-refill spout assembly to prevent further rotation of the closure 210. Additionally, in Figure 19e, the protrusions 217 or 216 may be provided on the inner wall edge of the assembly or closure. Vertically disposed ribs and bumps 216 on the lower portion of the closure 210 contact similar bumps and stops 217 disposed on the bottom of the container neck, thereby preventing rotation of the closure in a clockwise direction on the container. In Figure 19f, a similar projection or stop 219 is provided on the inner upper edge of the closure at a location above the threads, as is also depicted in Figure 3 with reference numeral 15. These similar contact barriers 218, or element 37 shown in Figure 4, located near the mouth of the container or spout assembly, prevent the closure from turning on the container once these barriers are in adjacent contact with each other. Finally, Figure 19g details the provision of a thread 222 inside the closure, wherein the thread 222 has a blunt end 221 . With the closure fully threaded onto the container, the blunt end 221 abuts a stop member 220 that is located below the mating threads of the container neck or spout assembly. Cooperating lugs or blocking means on the container or closure may have a retracement angle so as not to form a direct 90° angle, ie each of these lugs or blocking means is less than 90° relative to the innermost wall of the connecting lug. This construction results in the mating lugs being pulled together, and due to the angle of the opposing barriers, they grip each other and have a controlled blocking effect. All of these embodiments are effective in preventing excessive rotation, or misalignment, of the teeth or ratchets of the container and spout assembly or closure.

Finally, referring to Figure 20, the inner cover 231 and the outer cover 230 can be assembled in a separate second step, so that the inner cover including the anti-theft indicator ring 232 can be installed without the aforementioned problems due to pre-installation of the outer cover. Installed on the inner cover, the anti-theft indicator produced by the spoke is damaged. The inner lid 231 is first fabricated and mounted on the container so that the tamper indicating band 232 remains above the continuous bead 237 . Installing the modified inner cap on the spout or neck before installing the outer cap eliminates any interfering elements between the ratchets of the mating anti-theft indicator band when tightening the inner cap 231 . As mentioned above, after the inner cap 231 is screwed, the outer cap 230 is snapped onto the inner cap 231, forcing the anti-theft indicator band of the inner cap to move down and across the bead 237, or over the ratchet. Outer ribs 233 and 234 engage inwardly extending beads 235 and 236 such that the outer cover is retained on the inner cover. This design allows the webs connecting the inner cap to the tamper-indicating band to break more easily, which is desirable as described above, because it prevents the webs from being pre-broken due to the inner cap being screwed onto the container. The ratchets must block each other or the tamper-indicating tape bead passes the rotational friction of the retaining tape of the container mouth and pour spout.

plastic material used

The elements of the closure are molded from a plastic resin material which depends on their physical properties in order for them to perform the proper function required. The sleeve "H" is molded from a plastic resin material with high resistance to softening, eg polycarbonate, in order to avoid removal of the closure from the bottle "I" by heating. The spout is molded from a resin material that has a melting temperature similar to that of the sleeve "H" when ultrasonic welding is used to join these elements together.

Assemble the closure

Assembly of such non-refillable closures is accomplished by performing an initial assembly step to a final assembly step. The inner cover is pre-assembled in the outer cover. Pre-assemble the non-refill mechanism, place the lower valve in the middle ring, then place the glass bulb, then install the upper valve, and finally secure the pouring spout in the middle ring by applying pressure. When adhesive or ultrasonic welding is used to bond the non-refill mechanism to the retaining sleeve, the final assembly step is performed by screwing the inner and outer caps onto the spout.
