Description

  The present invention relates to a container in which a pouring part is composed of two film materials.

  As a container, it has a pouring part formed by laminating two flexible film materials and fusing both sides thereof, and in the normal state after filling the contents into the container, the two film materials Since the inner surface of the container is in close contact, the container that can close the pouring part without using means such as an open / close lid made of a separate member can reduce the volume of waste by configuring the entire container with a film material. At the same time, because the entire container is made of a single resin material and is easy to recycle and can be manufactured at low cost, it is not only a relatively low-viscosity fluid such as water or soft drinks, but also a shampoo or rinse. Are widely adopted as containers for fluids having relatively high viscosity (see, for example, Patent Documents 1 and 2).

  In the container, when the container body is filled with the contents and the body portion of the container body swells, the two front and back film materials constituting the body portion approach each other as they go to the dispensing portion side, In the vicinity of the boundary portion between the two and the pouring portion, the two film materials are closely adhered and bent along a parabolic seal line projecting toward the pouring portion, and the pouring portion is curved in a spoon shape. Thus, the two film materials constituting the extraction portion are in close contact with each other on the tip side of the seal line, and the extraction portion is closed.

.
In the container described in Patent Document 2, the width of the pouring portion is gradually reduced toward the tip so that the pouring portion is reliably closed, and the fusion portions on both sides of the pouring portion are fused. By forming the width wide on the upstream side and narrowing the downstream side, and forming the entire pouring part in a spoon shape in advance, the pouring part is closed in a normal state filled with the contents. .

  As the dispensing operation means, it is also preferable to attach a plate-shaped dispensing operation member that is elastically deformable around the middle portion in the width direction of the dispensing passage to at least one of both film materials in the dispensing portion. It is a form. In this case, for example, the two film materials are separated by a simple operation of picking the extraction operation member with the thumb and index finger and elastically deforming the extraction operation member outwardly in a curved shape. The part can be opened. In addition, according to the present invention, since the dispensing operation means can be composed of a simple plate-shaped dispensing operation member, an increase in the manufacturing cost of the container can be suppressed. Note that, as described above, the method of attaching the dispensing operation member to the film material is preferably attached by fusion bonding such as heat fusion or ultrasonic fusion, but it may be attached by bonding using an adhesive. it can. Further, the entire surface of the dispensing operation member facing the film material may be bonded to the film material by fusing or bonding, or at least the fold side portion of the facing surface may be bonded to the film material by fusing or bonding. You can also

  It is also a preferred embodiment that the dispensing operation member is provided in a face-to-face manner on the outer surfaces of both film materials in the dispensing portion. In this case, by picking two extraction operation members with a finger at the same time, the two film materials can be separated in a well-balanced manner, and the extraction portion can be opened with good stability.

  It is also a preferred embodiment to attach a shape maintaining member that holds the middle part in the length direction of the extraction passage to a bent state on at least one of both film materials in the extraction portion. With this configuration, when the contents are taken out, the shape maintaining member can be made straight and the contents can be taken out by operating the pouring operation means. When the pouring part is closed, the shape maintaining member Is folded and the pouring portion is held in a folded state, so that the pouring passage can be reliably closed so that the contents do not leak out. As the shape maintaining member, a metal wire, a metal wire coated with a resin, a synthetic resin material capable of holding a shape, or the like can be used as long as it can be held in a bent shape.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
As shown in FIGS. 1-4, the container 1 has the trunk | drum 2 and the extraction | pouring part 3 narrower than the trunk | drum 2 connected to it, and consists of two film materials of the front side and the rear side. The container main body 4 and the two film materials in the extraction section 3 are forcibly separated, the extraction operation means 10 for opening the extraction passage 5 and the middle portion in the length direction of the extraction passage 5 And a shape maintaining member 20 that holds the bent state.

  The container body 4 is composed of two film materials on the front side and the rear side, and a fused portion 6 is formed on the outer circumference of the two film materials over the entire circumference by heat fusion or ultrasonic fusion. The container body 4 is filled with a liquid content S. As a manufacturing method of this container body 4, for example, first, two film materials punched into the front shape of the container body 4 are manufactured, and then both film materials are overlapped, and as shown in FIG. The outer peripheral portion excluding the upper end portion of the body portion 2 opposite to the portion 3 side is fused by heat fusion or ultrasonic fusion to produce a container body 4 having an open upper end portion, and then the container body 4, after the contents S are filled from the upper end opening, the upper end opening is fused and sealed.

  A hooking hole 7 is formed at a substantially central portion in the left-right direction (length direction) of the fused part 6d at the upper end of the body part 2 on the side opposite to the pouring part 3 side, and the container body 4 has the hooking hole 7 formed therein. When the user takes out the contents S, it is hung on the hook F fixed on the wall W or the like and hung with the pouring portion 3 facing downward. First, as shown in FIG. In addition, the lower end 3a of the extraction portion 3 is cut off with a scissors or the like, the lower end portion of the extraction passage 5 is opened, and then the contents S are discharged from the extraction passage 5 and taken out.

  The contents S to be filled in the container body 4 can be suitably filled with cosmetics such as shampoos, rinses and conditioners, but other than cosmetics as long as the contents have fluidity such as liquid, gel or powder. It can be filled with food, medical and industrial contents.

  As the two film materials constituting the container body 4, a film material having a single layer structure made of a thermoplastic synthetic resin material that can be fused to each other can be adopted, or a sealant layer made of a thermoplastic synthetic resin material A laminate film having a multilayer structure composed of a single or a plurality of base material layers made of a functional material having functions such as gas barrier properties and light shielding properties can also be employed. The thickness of the film material is preferably set to 50 μm to 400 μm in consideration of the adhesion of the film material and the like.

  The body portion 2 includes a main body portion 2 a that is wider than the extraction portion 3 and a guide portion 2 b that connects the main body portion 2 a and the extraction portion 3. In the present embodiment, the extraction portion 3 is disposed at a position corresponding to the central portion in the left-right direction of the body portion 2, but is disposed at a position eccentric to the right or left side with respect to the central portion in the left-right direction. It can also be made. Moreover, the extraction | pouring part 3 can also be comprised so that an angle may be provided with respect to a perpendicular direction.

  In the state where the two film materials constituting the body portion 2 are overlapped, the width W1 between the inner edges 8a of the left and right fused portions 6a of the main body portion 2a is set to the same width from the upper end portion to the lower end portion, The width W2 between the inner edges 8b of the left and right fused portions 6b of the guide portion 2b is configured to become narrower as going to the extraction portion 3 side. However, the width W1 between the inner edges 8a of the left and right fusion parts 6a of the main body part 2a is not necessarily set to the same width from the upper end part to the lower end part of the main body part 2a. Therefore, it can be configured to be narrow, or it can be configured to be narrow in the middle in the height direction. Further, in the state where the two film materials constituting the body portion 2 are overlapped, an angle θ1 formed by the inner edge 8a of the fused portion 6a of the main body portion 2a and the inner edge 8b of the fused portion 6b of the guide portion 2b. Is preferably set to an angle larger than 90 ° so that the contents S can be used up to the end, but can also be set to 90 ° or less.

  The pouring part 3 is located between the inner edges 8c of the left and right fused parts 6c of the pouring part 3 as it goes to the tip side (lower end side) in a state in which the two film materials constituting it are overlapped. The width W3 is configured to be narrow. However, the width W3 can be set to the same width from the upper end portion to the lower end portion of the extraction portion 3.

  The width W3 of the upper end portion of the pouring part 3 is set to 1 mm or more and 50 mm or less, preferably 10 mm or more and 20 mm or less, more preferably 2 mm or more and 8 mm or less, and the inner edge 8c of the fused part 6c of the pouring part 3 and the guide An angle θ2 formed by the inner edge 8b of the fused portion 6b of the portion 2b is set to 60 ° to 165 °, preferably 90 ° to 150 °. Thereby, in the state which the content part S was filled and the trunk | drum 2 swelled, in the vicinity of the boundary part of the trunk | drum 2 and the extraction | pouring part 3, two film materials protrude toward the extraction | pouring part 3 side. Adhering along the parabolic seal line L, the extraction part 3 on the tip side of the seal line L bends in the out-of-plane direction along the seal line L, and forms a convex curved surface starting from the seal line L. By curving, the two film materials constituting it are brought into close contact with each other, the pouring passage 5 is closed in a liquid-tight manner, and the curved pouring portion 3 is picked and flattened with a finger, thereby pouring. The outlet passage 5 is opened so that the contents S can be discharged.

  However, even if the contents S is filled and the body part 2 swells due to the viscosity of the contents S, the waist of the film material, the combination of the numerical values of the width W3 and the angle θ2 of the upper end part of the pouring part 3, The content S leaks without the dispensing passage 5 being completely closed, or the two film materials constituting the dispensing portion 3 are firmly adhered to each other, and the dispensing portion 3 is flattened with fingers. In some cases, the contents S may not be discharged. In the present invention, even if the content S is slightly leaked from the dispensing passage 5, by providing the shape maintaining member 20, the shape maintaining member 20 is bent as shown in FIG. It is possible to prevent the contents S from leaking from the extraction passage 5 by closing the extraction passage 5. Further, even when the two film materials constituting the pouring portion 3 are firmly adhered and the pouring passage 5 cannot be opened even if the pouring portion 3 is operated with a finger, the pouring operation means 10 is used. Therefore, the contents S can be ejected by forcibly separating the two film materials constituting the extraction unit 3. For this reason, if only the two film materials constituting the pouring portion 3 are used, the pouring passage 5 cannot be opened even if the contents S leak from the pouring passage 5 to some extent or even if the pouring portion 3 is operated with a finger. The present invention can also be applied to the container body 4 having such a configuration, and the container for the combination of numerical values of the viscosity of the contents S, the waist of the film material, and the width W3 and the angle θ2 of the upper end of the pouring part 3 The design freedom of the main body 4 can be expanded. Moreover, even if the extraction | pouring part 3 is operated many times and the waist of the film material in the extraction | pouring part 3 becomes weak, it can prevent effectively that the content S leaks from the extraction | pouring channel | path 5. FIG. However, in order to reliably prevent the leakage of the contents S from the dispensing passage 5, the dispensing passage 5 is filled with the contents S and the trunk portion 2 is expanded without using the shape maintaining member 20. Is preferably configured to be completely closed.

  The shape maintaining member 20 is formed of an elongated plate-like or bar-like member made of a material that can be folded by hand and can be held in a folded shape even when the hand is released. Attached along the fusion part 6c to the front side or the rear side of the middle part in the height direction of the attachment part 6c. However, the shape maintaining member 20 can be attached to both sides of the fusion portion 6, and only one piece is attached along the extraction passage 5 in the middle of the extraction portion 3 in the left-right direction (width direction). It is also possible to wear it. The length of the shape maintaining member 20 can be arbitrarily set, but is preferably set to 50 mm to 50 mm because it is used after being bent. As a material constituting the shape maintaining member 20, a metal material such as copper or aluminum, a metal-coated metal wire made of the metal material, or a synthetic resin material capable of maintaining the shape made of a polyolefin-based synthetic resin is employed. it can.

  When closing the extraction passage 5 using the shape maintaining member 20, as shown in FIG. 3 (b), the middle portion in the height direction of the extraction portion 3 is bent together with the shape maintaining member 20, and the extraction passage 5 is bent. 5 will be kept closed. Further, when opening the dispensing passage 5, as shown in FIG. 1 (b), the shape maintaining member 20 is straightened to facilitate opening the dispensing passage 5, and then the dispensing operation means 10 is changed. By operating, the contents S are discharged. However, the shape maintaining member 20 can be omitted.

  As shown in FIGS. 1 to 4, the dispensing operation means 10 is a plate-shaped dispensing operation member 11 having an isosceles trapezoidal shape, which is adhered to the outer surface sides of the two film materials constituting the dispensing portion 3. A crease 12 made of a concave groove extending in the vertical direction is formed from the upper end portion to the lower end portion of the dispensing operation member 11 at a substantially central portion in the left-right direction on the outer surface side of the dispensing operation member 11.

  Synthetic resin materials such as polypropylene resin, polyethylene resin, polystyrene resin, and polyvinyl chloride resin can be used as the material for the dispensing operation member 11, but since it does not break even if it is repeatedly folded at the fold 12, polypropylene resin is used. It can be suitably employed.

  The dispensing operation member 11 is stuck to the film material at the sticking portion 13 through heat fusion, ultrasonic fusion, or an adhesive. The pouring operation member 11 can also stick the entire surface facing the pouring part 3 to the film material, or can stick only the region facing the pouring passage 5 to the film material, Only 12 vicinity can also be stuck on a film material. It is also possible to provide the dispensing operation member 11 only on one film material of the dispensing part 3, and the dispensing operation member on at least one inner surface side of the two film materials constituting the dispensing part 3. 11 can also be attached.

  Although the width in the left-right direction of the dispensing operation member 11 can be configured to be narrower than the width of the dispensing passage 5, in order to improve the operability of the dispensing operation member 11, It is preferable that the width is equal to or greater than that, and it can be provided so as to protrude from the extraction portion 3 to the left and right sides. When configured to be wider than the pouring passage 5, the outer edge 16 of the pouring operation member 11 corresponds to the inner edges 8c of the left and right fused portions 6c of the pouring portion 3 as shown in FIG. It is preferable to form the outer groove. The height position of the dispensing operation member 11 with respect to the dispensing portion 3 can be arbitrarily set, and is provided at the lower portion in the height direction, but can also be provided at the middle portion in the height direction or at the upper portion in the height direction. is there. However, the shape maintaining member 20 is provided at an interval in the height direction, and the contents S and the outside air are introduced into the extraction passage 5 so that the two film materials in the extraction portion 3 are separated. Is preferably provided at the upper part or the lower part of the extraction part 3.

  The crease 12 is continuously formed from the upper end portion to the lower end portion of the dispensing operation member 11, but can be formed only in the middle portion or both end portions in the height direction, or formed intermittently. You can also. Moreover, although it provided only in the outer surface side of the extraction | pouring operation member 11, it provides in the inner surface side (film material side) of the extraction | pouring operation member 11, or it provides in both the outer surface side and inner surface side of the extraction | pouring operation member 11. It is also possible. Furthermore, although the crease 12 is formed with a U-shaped groove, the crease 12 may be formed with a V-shaped groove, or the fold 12 may be formed by cutting.

  In this dispensing operation means 10, as shown in FIG. 4 (b), the two dispensing operation members 11 are picked by fingers from both the left and right sides, and a force is applied as indicated by an arrow A, along the crease 12. Then the bending operation member 11 is bent in an L shape so that the central portion in the left-right direction of the extraction operation member 11 protrudes to the front and rear sides, thereby forcing the two film materials constituting the extraction portion 3 The extraction passage 5 can be opened by being spaced apart from each other. Further, when the finger is released from the dispensing operation member 11, the dispensing operation member 11 returns to the flat original shape shown in FIG. 4A due to the elasticity of the material, and the two film materials are overlapped. Thus, the pouring passage 5 is closed.

  Thus, in this container 1, the content S is arrange | positioned by the capillary phenomenon between the two film materials which comprise the extraction | pouring part 3, and both film materials closely_contact | adhere through this content S At the same time, in the state in which the body portion 2 is swollen with the contents S, in the vicinity of the boundary portion between the body portion 2 and the extraction portion 3, two film materials project toward the extraction portion 3 side. The sticking portion 3 is in close contact with the seal line L, and the extraction portion 3 on the tip side of the seal line L is bent in an out-of-plane direction along the seal line L3, and is curved into a convex curved shape starting from the seal line L. Thus, the two film materials constituting it are closely adhered, the extraction passage 5 in the extraction portion 3 is closed in a liquid-tight manner, and the content S does not leak from the extraction portion 3, The contents S can be accommodated in the container 1. On the other hand, since the two film materials constituting the pouring part 3 are forcibly separated by operating the pouring operation means 10, the pouring part 3 is constituted in order to surely prevent the leakage of the contents S. Even in the case where the two film materials are closely adhered to each other and the extraction portion 3 is firmly closed, the contents S can be easily and reliably discharged by the operation of the extraction operation means 10. Further, when the contents S leak from the pouring part 3, the shape maintaining member 20 is bent as shown in FIG. 3B, and the pouring passage 5 is securely closed to leak the contents S. Can be prevented.

  Instead of the dispensing operation member 11, it is also possible to use a dispensing operation member 11A in which the fold 12 is omitted, such as a dispensing operation means 10A shown in FIG. In this case, the dispensing operation member 11A is made of a plate-like member made of a metal or a synthetic resin that can be elastically deformed, and the two dispensing operation members 11A are picked by fingers from the left and right sides, and FIG. As shown in b), the center part in the left-right direction of the pouring operation member 11A is projected in a curved shape forward and backward, and the two film materials constituting the pouring part 3 are forcibly separated, and pouring is performed. The exit passage 5 is opened.

  Further, instead of the dispensing operation means 10A, a dispensing operation means 10B as shown in FIG. 6 can be provided. The pouring operation means 10 </ b> B has a flat plate portion 15 that is stuck to the pouring portion 3 at the sticking portion 13 and a mounting portion 16 that extends outward from the left and right ends of the flat plate portion 15 at substantially right angles.
