Description

[Technical Field]

[0001] The present invention relates to a pouch container having a synthetic resin dispensing device attached to a bag body. [Background technology]

[0002] In recent years, pouch containers, which are bags made of laminated films with high gas barrier properties and to which a resin dispensing device is attached, have become widely used as packaging for fluid products such as shampoos and jelly drinks. In these pouch containers, the dispensing device generally consists of a body welded to the bag body and a cap that closes the body, and the cap is generally a screw cap.

[0003] On the other hand, for example, screw caps and hinge caps are widely used as closure devices for bottles, and Patent Document 1 discloses a composite closure structure in which a stopper-type hinge cap is attached to the screw cap of a pouch container. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2007-204063 Summary of the Invention [Problem to be solved by the invention]

[0005] Screw caps and hinge caps have different functions and are used for different purposes. Screw caps have the advantage of being able to be tightly tightened and sealed, and are often used as caps for PET beverage bottles. In this case, to ensure tamper-evident functionality, a tamper-evident band (or PP band) is connected to the bottom of the cap body via a group of bridges, and all or most of the bridges are torn off upon initial opening.

[0006] On the other hand, hinge caps are characterized by the ability to open and close with a single touch, and are therefore often used as caps for seasoning bottles, which are often dispensed in small amounts.To ensure a tight seal during distribution, the hinge cap is attached to the cap body that is attached to the bottle, and the cap body is equipped with a closure plate that can be torn by pulling on it, like a pull tab.

[0007] In the case of seasoning bottles, even when screw caps are used, the bottle body is often a stopper type, and the screw cap is screwed onto the bottle body. This is due to the fact that it can be reliably sealed with a closure plate and the amount of dispensed can be easily set.

[0008] As mentioned above, pouch containers are becoming more popular as a means of packaging fluid contents such as jelly-like foods, and screw caps are often used as the caps for these containers. However, screw caps require a rotating operation to open or close, which makes them difficult to use, especially for pouch containers that are often used for small amounts of food.

[0009] One solution to this problem would be to change the dispensing device for pouch containers to a hinge cap system, but a simple hinge cap system poses safety issues because no traces are left behind if the product is tampered with during distribution. There is also the concern that the hinge cap may easily open when pressure is applied to the bag.

[0010] The present invention has been made to improve this current situation. [Means for solving the problem]

[0011] The present invention includes various configurations, and typical configurations are specified in each claim. Of these, the invention of claim 1 is as follows: "It consists of a bag body filled with contents and a synthetic resin dispensing device that dispenses the contents filled in the bag body, The dispensing device comprises a welded portion that penetrates into the bag body, a dispensing portion that is integrally continuous with the welded portion and exposed to the outside of the bag body, a pivotable hinge cap that is integrally connected to the dispensing portion via a hinge, and tamper evidence means that is provided with a weakened portion that breaks when the hinged cap is first opened. The structure is as follows.

[0012] The invention of claim 2 is a development example of claim 1, The tamper evidence means comprises a claw member provided on the outer periphery of the hinge cap and a receiving member provided on the spout portion so that the claw member is forcefully fitted into the receiving member, The claw members are connected to the outer periphery of the hinge cap via weakened portions that break upon the initial pivoting of the hinge cap. The structure is as follows.

[0013] The invention of claim 3 is a development example of claim 2, "The hinge cap has a top plate that overlaps the top surface of the pouring portion, and a sealing tube that protrudes downward from the top plate and fits tightly against the inner surface of the pouring portion, A tab for raising and rotating the top plate is provided at an end of the top plate opposite to the hinge, and an arc-shaped edge member is integrally formed on the outer periphery of the top plate via a breakable weakened line, and the claw member is formed on the edge member; The spout portion is formed with an engagement recess into which the claw member is forcibly fitted by sealing with the hinge cap, The weakened lines are configured to break sequentially from near the tab to near the hinge when the hinge cap is first opened. The structure is as follows.

[0014] The invention of claim 4 is also an example of the development of claim 2, "The spout portion has a spout portion long enough to be held in a person's mouth and a flange that defines the lower end of the spout portion, The hinge has a hinge rod rotatably connected to the flange via a first hinge, and a hinge cap rotatably connected to the upper end of the hinge rod via a second hinge. The structure is as follows.

[0015] The invention of claim 5 is a development example of any one of claims 1 to 4, "A closure plate that seals the inside of the pouring portion is integrally formed within the pouring portion via a closed-loop, thin-walled score, and a pull ring that can be pulled up with a person's finger to break the score is integrally connected to the closure plate." The structure is as follows. [Effects of the Invention]

[0016] In the present invention, the dispensing device is equipped with a tamper evidence means, which makes it possible to confirm the fact of unauthorized access during distribution and ensure safety. As mentioned above, pouch containers are often used to package highly viscous fluids such as jelly-like foods and shampoo. When the fluid has a high viscosity, the necessary sealing can be ensured even if the sealing tube of the cap is tightly fitted to the inner surface of the dispensing part, and the sealed state is maintained by the tamper evidence means.

[0017] The hinge cap also allows for one-touch opening and effortless dispensing. Therefore, the present invention can be said to match the characteristics of the contents, making it easy to open and dispense, while ensuring sealing function and safety during distribution.

[0018] The tamper evidence means can have a variety of structures, but if a configuration is adopted in which the weakened portion is broken by opening the hinge cap, as in claim 2, the weakened portion cannot be reconnected once broken, thereby ensuring the tamper evidence function.

[0019] In claim 3, the weakened line connecting the arc-shaped edge member and the top plate tears in order starting from the side closest to the tab, so that the pulling force can be concentrated in a narrow area of ​​the weakened line, making it easy to open.

[0020] By adopting the configuration of claim 4, the hinge cap becomes a two-stage bending type, which allows the hinge cap to be opened and closed while exposing a spout long enough to be held in a person's mouth. Therefore, it is suitable for use in pouch containers for packaging jelly-like foods. In this case, providing the hinge cap with a cover tube to protect the spout is hygienic.

[0021] In the configuration of claim 5, the dispensing portion can be kept closed by the closing plate, so the seal can be reliably maintained during distribution. Therefore, it can be easily applied to packaging low-viscosity liquids such as soft drinks, seasonings, various liquid chemicals, and solvents, improving the commercial value.

DETAILED DESCRIPTION OF THE INVENTION

[0023] (1) Basic structure of the first embodiment Next, embodiments of the present invention will be described with reference to the drawings. First, a first embodiment shown in Figures 1 to 5(A) will be described. The pouch container is composed of a bag body 1 made of a laminated film and a dispensing device 2 attached to the upper end of the bag body 1.

[0024] The bag body 1 is formed in a generally rectangular shape with the top and bottom longer when viewed from the front, and the dispensing device 2 is attached to the middle part of the top of the bag body 1. The bag body 1 can be, for example, a standing pouch made of three films: front and back films and a bottom film. Alternatively, various structures can be adopted, such as a non-standing type (hanging type) that does not have a bottom film, or a gusset-folded type.

[0025] For example, as shown in Figure 2, the dispensing device 2 comprises a welding part 3 to which the bag body 1 is welded, a dispensing part 4 (cylindrical part) that is integral with and continuous with the welding part 3 and exposed above the bag body 1, and a hinge cap 5 that is provided integrally with the dispensing part 4. The dispensing part 4 has upper and lower flanges 6 and 7. The two elements, the welding part 3 and the dispensing part 4, can also be collectively referred to as a main body.

[0026] The welded portion 3 is eye-shaped when viewed in the axial direction. Therefore, when the welded portion 3 is used as a reference, the dispensing device has a longitudinal direction and a width direction (short direction). The welded portion 3 has three horizontal ribs 8 extending in a direction transverse to the axis and a vertical rib 9 connected to the tip of the horizontal ribs 8. The lower flange 7 is continuous with the welded portion 3 and has an elongated hexagonal shape when viewed in the axial direction. The lower flange 7 also functions as a stopper that positions the upper end of the bag body 1.

[0027] As described above, the welded portion 3 has a longitudinal direction and a width direction, but in the following, the longitudinal direction and width direction of the welded portion 3 will be used as a means of identifying the direction of the dispensing device 2, and the longitudinal direction of the welded portion 3 will be identified as the front-to-back direction, and the width direction of the hinge portion 12 will be identified as the left-to-right direction.

[0028] The upper flange 6 is circular, and when transported on a filling line or the like, the area between the upper and lower flanges 6, 7 is sandwiched between a pair of chutes. Therefore, the pouch container is transported with the upper flange 6 resting on the chute. A position-maintaining plate 10 is provided between the upper and lower flanges 6, 7 to prevent the pouch container from rotating when transported on the chute (the area between the upper and lower flanges 6, 7 may be formed into a square when viewed in the axial direction).

[0029] The injection device is manufactured by injection molding using synthetic resin as the material, and the mold device has a fixed mold (cavity) and a movable mold (core) that move relative to each other in the axial direction as the basic mold, but because the injection device has ribs 8, 9 and flanges 6, 7, a pair of split molds that move relative to each other in the left-right direction perpendicular to the axial direction are also used.

[0030] (2) Hinge cap A large diameter ring portion 11, whose upper end surface is flush with that of the spout portion 4, is integrally connected to the upper end of the spout portion 4, and a hinge cap 5 is integrally connected to one end of the large diameter ring portion 11 in the front-to-rear direction via a hinge portion 12. The hinge portion 12 is composed of one center hinge portion 13 and two side hinge portions 14 on the left and right. The center hinge portion 13 is responsible for the function of accurate positioning, and the side hinge portions 14 are responsible for a reinforcing function.

[0031] The hinge cap 5 has a top plate 15 that overlaps the upper end of the spout 4, and a sealing tube (center leg) 16 that fits tightly inside the spout 4. A tab 17 for a finger hook (for lifting) is protruding from the top plate 15 on the side opposite the hinge 12. Furthermore, arc-shaped edge members 18 are arranged on both the left and right sides of the top plate 15, and protrusions 20 are integrally formed with the edge members 18, with outwardly facing hook-shaped claw members 19 protruding upward in the open state. Four claw members 19 are formed in a line in the circumferential direction, but the number can be set as desired.

[0032] The front and rear ends of the edge member 18 extend to the tab 17 and the hinge portion 12, and the edge member 18 is connected to the top plate 15, the side hinge portion 14, and the tab 17 via a thin weakened line (score) 22 formed by a V-groove 21 that opens upward when the cover is open. The V-groove 21 can also be opened in the opposite direction. Also, a groove of equal width can be formed instead of the V-groove 21.

[0033] For example, as shown in Figures 3(A) and (B), the lower end of the edge member 18 is connected to the spout 4 via a plurality of bottom plates 23 separated in the circumferential direction, and therefore an upwardly opening space is formed between the spout 4 and the edge member 18, and the protrusions 20 of the hinge cap 5 are set to fit into this space, and as also shown in Figure 4, engagement holes 24 into which the claw members 19 of the hinge cap 5 engage are formed intermittently along the circumferential direction, in a state similar to drilling holes in the bottom plate 23.

[0034] As shown in Fig. 4, inclined surfaces 19a, 24a that guide the insertion of claw member 19 are formed at the tip of claw member 19 and the lower end of engagement hole 24. Claw member 19 is forcibly fitted into engagement hole 24 mainly by elastically deforming edge member 18. Upper flange 6 is disposed so as to be adjacent to the lower end of claw member 19 in the open state. During manufacturing (molding), claw member 19 is formed using a split mold, and V-groove 21 is formed using a fixed mold (cavity).

[0035] (3) Summary In the above configuration, the pouch container is generally shipped with the dispensing device 2 in an open state fixed to the bag body 1. At the destination, the contents are filled while being transported through a chute, and then the hinge part 12 is tilted down to open the lid and seal it. When the lid is opened, the sealing tube 16 fits tightly into the dispensing part 4, but since the contents packaged in this type of pouch container are almost always high-viscosity fluids and the tightly fitted state is maintained by the claw member 19, the contents will not leak out during distribution.

[0036] When a consumer who has purchased the product grasps the welded portion 3 with one hand and applies an upward force to the tab 17 with the other hand, the hinge cap 5 rotates upright with the hinge portion 12 as a fulcrum, and with this movement, the weakened line 22 is torn from one end continuous with the tab 17 to the other end connected to the hinge portion 12, and the seal tube 16 is removed from the pouring portion 4 and opened.

[0037] If the package is tampered with during distribution, even if the hinge cap 5 is reclosed, the presence of a cut at the boundary between the top panel 15 and the edge member 18 will make it possible to visually confirm the tampering, and the absence of resistance from the weakened line 22 will also enable tampering to be confirmed by touch. Therefore, the tamper-evident function is ensured.

[0038] In the embodiment, because the vertical height of the spout 4 is not particularly high and the bag 1 remains in the spout 4 after opening, it is not intended for consumers to hold the spout 4 in their mouths to ingest the contents, but rather for the bag 1 to be opened and then pressurized to expel the contents. In other words, it is intended for the pouch container to be exhaled by pushing or pouring out with the spout 4 facing downward. Furthermore, the pouch container of the embodiment can have a lower height of the spout 4 than a screw cap, which also contributes to cost reduction.

[0039] The pouch container is transferred in the front-to-back direction (longitudinal direction) during the filling process, but in this embodiment, the spout 4 and hinge cap 5 extend in the front-to-back direction, so the pouch container can be transferred smoothly on the filling line. Note that it is also possible to ship the pouch 1 and the spout device 2 in an open state separately, and then fill the contents into the pouch 1 and then weld the pouch 1 to the spout 4.

[0040] In the embodiment, the weakened line 22 extends to the area between the tab 17 and the side hinge portion 14, but it is also possible to leave a gap (slit) between the tab 17 and the side hinge portion 14 and the bag body 1 without providing the weakened line 22 at the area of ​​the tab 17 and the side hinge portion 14. In this case, the presence of the slit, particularly at the area of ​​the tab 17, forms an opening for tearing the weakened line 22, making it possible to easily tear (break) the weakened line 22.

[0041] 5(B), the weakened portion can be formed of a plurality of bridges 25 arranged intermittently along the inner periphery of the edge member 18. In this case, the external force caused by raising the hinge cap 5 can be concentrated on each bridge 25, making it easier to open. If the left and right groups of bridges 25 are arranged asymmetrically, the external force caused by raising the hinge cap 5 can be concentrated on each bridge 25, further improving the ease of opening.

[0042] As shown by the dashed line in Figure 4, a closure plate (removal plate) 50 can be integrally provided in the upper internal space of the pouring portion 4 via a thin annular score 51, and a pull ring 52 can be provided at one end of the closure plate 50 via a pillar 53 (this also applies to other embodiments). With this configuration, the interior of the pouring portion 4 is sealed with the closure plate 50, ensuring a reliable seal during distribution. Therefore, it can be used without problems for packaging low-viscosity liquids, improving marketability (versatility).

[0043] Furthermore, since the spout 4 is closed by the closure plate 50, the strength of the attachment of the middle foot 16 to the spout 4 can be reduced, and the force required for the consumer to first lift the tab 17 to release the seal can be reduced. This also has the advantage of making the seal release easier. The shape and size of the closure plate 50 can be set as desired. Therefore, the closure plate 50 can also be connected to a flange protruding inward from the spout 4 via an annular score 51.

[0044] (4) Other embodiments Next, other embodiments shown in Figure 6 and subsequent figures will be described. In the embodiment of Figures 6 to 9(A), the spout part 4 has a spout part 26 that is long enough for a person to hold in their mouth. The spout part 4 is formed with an upper flange 6, a lower flange 7, and a middle flange 27, and a hinge cap 5 is connected to one end of the upper flange 6 in the front-to-rear direction via a hinge rod 28 so as to be able to open and close.

[0045] The hinge rod 28 is a component of the hinge means, and its lower end is connected to the upper flange 6 via a lower hinge portion 29 so as to be rotatable back and forth, and the top plate 15 of the hinge cap 5 is connected to the upper end of the hinge rod 28 via an upper hinge portion 30 so as to be rotatable up and down. The upper and lower hinge portions 29, 30 are composed of center hinge portions 29a, 30a and curved side hinge portions 29b, 30b. The center hinge portions 29a, 30a are responsible for the positioning function, and the side hinge portions 29b, 30b are responsible for the reinforcing function and the posture maintaining function.

[0046] As shown in Figure 6(B), the spouting device 2 is molded with the hinge rod 28 and the hinge cap 5 in an open state, but the hinge rod 28 and the hinge cap 5 are formed using only a fixed mold and a movable mold. Therefore, the hinge rod 28 and the hinge cap 5 are formed in an open state protruding outside the welded portion 3. For this reason, one end of the upper flange 6 in the front-rear direction protrudes outside the welded portion 3, and as a result, the hinge rod 28 is formed in a substantially L-shape.

[0047] The hinge cap 5 comprises a top plate 15, a seal tube 16, and a tab 17, and edge members 31 that are arc-shaped in plan view and that are in intimate contact with the outer peripheral surface of the upper end of the spout portion 26 are formed integrally on the left and right sides of the top plate 15, and one claw member 32 that is outwardly hook-shaped and extends in the circumferential direction is formed integrally with the outer peripheral surface of the edge member 31 via multiple bridges 33. Note that weakened lines (thin-walled scores) can also be used instead of the bridges 33, and this also applies to the following embodiments.

[0048] Meanwhile, an engaging frame 34, which is arc-shaped in plan view, is integrally formed at the upper end of spout 26, into which rim member 31 and claw member 32 fit from above. A receiving rib 35 is provided below engaging frame 34 on spout 26, adjacent to the lower ends of rim member 31 and claw member 32. Receiving rib 35 is positioned within the space enclosed by engaging frame 34 in plan view (therefore, during molding, the upper surface of receiving rib 35 is formed by a solid mold (cavity)). Even if claw member 32 is torn off, it is received by receiving rib 35 and will not fall off. This prevents environmental pollution and the risk of being accidentally swallowed by small children, and also promotes recycling.

[0049] The claw members 32 are forcibly fitted into the engagement frame 34 from above mainly by elastically deforming the engagement frame 34. The claw members 32 and the engagement frame 34 are formed with inclined guide surfaces 32a, 34a to facilitate the forcible fitting of the claw members 32.

[0050] This embodiment also has the same basic function as the first embodiment, and the tamper-evident function is exhibited when bridge 33 is torn off as hinge cap 5 is first raised. This embodiment also has the advantage that hinge cap 5 does not get in the way of a person sucking the contents into their mouth, due to the synergistic effect of hinge rod 28 falling significantly outward from spout portion 26 and side hinge portions 29b, 30b maintaining the open state of hinge cap 5. In this embodiment, hinge cap 5 is connected to the upper end of hinge rod 28, allowing for smooth fitting and unfitting of seal tube 16 and edge member 31.

[0051] In the stoppering process (sealing process) of the hinge cap 5 after the contents have been filled, a punch 36 having a tubular portion 36a that presses the claw member 19 is used, as shown by the dashed line in Fig. 7(C). When this punch 36 is used, no external force is applied to the bridge 33 during stoppering, so that the bridge 33 can be prevented from being torn off during stoppering.

[0052] Figure 6(C) shows a third embodiment as a modification of the second embodiment. In this embodiment, the engaging frame 34 is connected to the upper end of the spout 26, and the claw members 32 protrude downward from the outer periphery of the top plate 15 via a group of bridges 33 (or thin-walled scores). Therefore, in this embodiment, the bridges 33 are exposed to the outside of the spout 26. In this embodiment, only the claw members 32 are surrounded by the engaging frame 34, so the protruding dimension of the engaging frame 34 can be reduced. This allows a person to hold the spout 26 in their mouth without any discomfort.

[0053] 8 shows a fourth embodiment, which is a modification of the second embodiment, in which hinge rod 28 is provided with a pair of left and right stopper pieces 37 that abut against or are close to the outer circumferential surface of spout portion 26. This provides high stability.

[0054] The fifth embodiment shown in Figure 9(A) is also a modification of the second embodiment, and in addition to the configuration of the second embodiment, this embodiment is provided with a cover tube 38 that surrounds the spout portion 26. Therefore, the spout portion 26 does not become dirty during distribution, making it hygienic. The cover tube 38 hangs down from the outer periphery of the top plate 15, and forms an opening 39 that exposes the rim member 31 and the engagement frame 34. This configuration can also be applied to other embodiments such as Figure 6(C).

[0055] The cover tube 38 is split on the side of the hinge rod 28. Therefore, the cover tube 38 can be deformed by expanding left and right from the side of the hinge rod 28 against its elasticity. Furthermore, in the second and subsequent embodiments, the hinge cap 5 can be swung by the rotation of the hinge rod 28 and the rotation of the hinge cap 5. In this way, the cover tube 38 can be fitted into and removed from the spouting portion 4 while being made as compact as possible due to the synergistic effect of the ability to expand and deform the cover tube 38 and the ability of the hinge cap 5 to swing. Note that the cover tube 38 only needs to be formed in a state that is expanded mainly in the front-to-rear direction, and does not need to be expanded left and right.

[0056] 9(B) has almost the same structure as the first embodiment. The only difference from the first embodiment is that a downward engaging claw 41 is provided at the base of the tab 17, and a notch 42 is formed on the outer circumferential surface of the large diameter ring portion 11 of the spouting portion 4, into which the engaging claw 41 engages when the lid is closed.

[0057] In this embodiment, when the hinge cap 5 is opened or closed, the engagement claw 41 engages with and disengages from the notch 42 against its elasticity, providing a tactile click feeling when the hinge cap 5 is closed or opened. This makes it easy to know when the hinge cap 5 is switched between the closed and open states. Furthermore, because the engagement claw 41 maintains the closed state, the hinge cap 5 can be prevented from opening easily for some reason.

[0058] 10 shows a seventh embodiment. In this embodiment, the spout portion 4 is short and does not have a spout portion, as in the first embodiment, and the spout portion 4 and the hinge cap 5 are directly connected via the hinge portion 12, as in the first embodiment. On the other hand, as in the second embodiment, a combination of an arc-shaped engagement frame 34 provided on the spout portion 4 and a claw member 32 provided on the hinge cap 5 is used as a means for maintaining the hinge cap 5 in a sealed state.

[0059] The engagement frame 34 is located near the upper end of the spout 4, and extends long in an arc shape along the circumferential direction except for a certain range on the hinge 12 side. On the other hand, the claw members 32 are formed in three pairs (multiple pairs) on both sides of the center line connecting the tab 17 and the hinge 12. Therefore, the engagement frame 34 has three pairs of engagement holes 43 corresponding to the three pairs of claw members 32. Each claw member 32 and the top plate 15 are connected via two bridges 33, but the number of bridges 33 can be set as desired.

[0060] A receiving rib 35 is disposed below the engaging frame 34, and the receiving rib 35 has a closed loop shape that extends around the entire circumference. However, since the receiving rib 35 is intended to receive torn claw members 32, it is possible to dispose the receiving rib separately at each claw member 32. In this embodiment, an engaging claw 41 protrudes downward from the base of the tab 17, and the engaging claw 41 is adapted to engage with and disengage from a dummy engaging hole 44 provided in the engaging frame 34.

[0061] The pouch container of this embodiment is similar to the first embodiment and is used to package contents that are manually squeezed out by a person. Therefore, it is not intended for use with a person sucking up the contents into their mouth. It can also be used to package liquid foods, such as dressing, that are simply squeezed out by a person. In either case, when the tab 17 is lifted from the sealed state, the group of bridges 33 are torn off in order, starting with those closest to the tab, and the pouch is opened. Therefore, it exhibits a tamper-evident function.

[0062] In this embodiment, although the spout 4 is short, its tip is exposed when opened, making it neat and easy to see the state of the contents being dispensed. In other words, the state of the contents being dispensed from the spout 4 can be clearly seen. Therefore, the contents can be easily pushed out.

[0063] Although the embodiments of the present invention have been described above, the present invention can be embodied in various other ways. For example, the upper part of the bag body 1 can be formed into a trapezoid shape, with the spout device fixed to the apex. Alternatively, the spout part 4 can be fixed at an angle to a corner of the bag body 1. Various structures can be used as tamper evidence means, such as interlocking claw members or perforated weakened lines. The welded part may be cylindrical.
