Patent Application
20240351749
The present invention relates to a pouch container.
As a conventional pouch container, JP 2015-134626 A (Patent Document 1) discloses a flexible packaging body including a storage portion surrounded by a seal portion formed by overlapping two films and sealing peripheral portions of the films. An unsealed portion where the films are not sealed is formed in the peripheral portion surrounded by the seal portion. A cut line portion defining a grip hole is formed in the unsealed portion.
Patent Document 1: JP 2015-134626 A
However, since the two films are not bonded to each other in the unsealed portion, when the cut line portion is formed only in the unsealed portion as disclosed in Patent Document 1, the two films may separate easily at the portion where the cut line portion is formed. The films especially tend to separate easily at both end portions of the cut line portion, which is curved in an arc shape. When multiple pouch containers are conveyed in a stacked state, peeled portions at end portions of the cut line portions of the stacked pouch containers may get caught on each other. When one of the stacked pouch containers is moved in this state, force is concentrated on the caught portion and the film rips at the end portions of the cut line portion.
On the other hand, in a case in which the unsealed portion is not provided and the cut line portion is formed entirely in the seal portion to prevent the films from separating at the unsealed portion, when folding a tongue portion formed by the cut line portion to form a gripper, it is difficult to fold the tongue portion because the fold line portion is rigid. This makes the gripper more difficult to use.
The present invention has been made in view of the above problems, and an object of the present invention is to provide a pouch container that can improve usability while suppressing damage to films.
A pouch container according to the present disclosure includes a pair of film sheet parts bonded to each other at a seal portion. The pouch container includes a storage space configured to store contents, and a peripheral portion located outside the storage space and provided with the seal portion. The peripheral portion includes a first cut line portion forming a tongue portion. The first cut line portion includes a first end portion and a second end portion. The first end portion includes a first curled portion curled toward the second end portion. The second end portion includes a second curled portion curled toward the first end portion. The seal portion includes a first curled portion seal area sealing the first curled portion and a second curled portion seal area sealing the second curled portion. The peripheral portion includes an unsealed area in which the pair of film sheet parts are not sealed, the unsealed area including a portion located between the first curled portion seal area and the second curled portion seal area.
Note that the pair of film sheet parts may be formed of two film sheets or may be formed by folding one film sheet.
In the pouch container according to the present disclosure, at least one of the first curled portion seal area and the second curled portion seal area may be formed in an island shape inside the unsealed area.
The pouch container according to the present disclosure includes a bottom portion and a ceiling portion. In this case, the first end portion may be located closer to the ceiling portion than the second end portion. The first curled portion seal area may be formed in an island shape inside the unsealed area, and the second curled portion seal area may be located outside the unsealed area.
The pouch container according to the present disclosure includes a bottom portion and a ceiling portion. In this case, the first end portion may be located closer to the ceiling portion than the second end portion. Further, the first cut line portion may include an extending portion connected to the first end portion and extending toward the storage space. In addition, the extending portion may include a bulging portion bulging toward an inside of the unsealed area.
In the pouch container according to the present disclosure, the first cut line portion may include multiple microjoint portions connecting an outer side and an inner side of the first cut line portion. In this case, all of the multiple microjoint portions are located closer to the storage space than a fold line of the tongue portion, the fold line connecting the first curled portion and the second curled portion at the shortest distance.
In the pouch container according to the present disclosure, the pouch container includes a bottom portion and a ceiling portion. In this case, the first end portion may be located closer to the ceiling portion than the second end portion. The first cut line portion may include an extending portion connected to the first end portion and extending toward the storage space. Further, the seal portion may include a second cut line portion at a position closer to the ceiling portion than the extending portion, the second cut line portion facing the extending portion and the first end portion in a direction in which the bottom portion and the ceiling portion are aligned. In this case, the peripheral portion may include a bridge portion formed between the second cut line portion and both the extending portion and the first end portion. The second cut line portion may include a first portion extending in a direction in which the extending portion extends, and second portions extending from both ends of the first portion toward the ceiling portion.
According to the present invention, a pouch container can be provided that can improve usability while suppressing damage to films.
Hereinafter, embodiments of the present invention will be described with reference to the figures. Note that in the embodiments described below, identical or common portions are denoted by the same reference signs in the drawings, and description thereof will not be repeated.
As illustrated in
The pouch 10 includes the pair of front and back film sheet parts 11 and a gusset sheet part 12. The gusset sheet part 12 is folded inward from a lower portion of the pair of film sheet parts 11 to form a bottom gusset portion 13.
The pouch 10 is formed into a bag shape by overlapping the pair of film sheet parts 11 and the gusset sheet part 12 and sealing peripheral portions of these films while in contact with each other. More specifically, the peripheral portions of the folded gusset sheet part 12 are heat-sealed to lower peripheral portions of the pair of film sheet parts 11, and peripheral portions of the pair of film sheet parts 11 that are not heat-sealed to the gusset sheet part 12 are heat-sealed to each other. Note that the pair of film sheet parts 11 may be formed of two film sheets or may be formed of one folded film sheet.
Multiple notch portions 14 are formed on both side edges of the gusset sheet part 12, and lower edge portions of both side edges of the pair of film sheet parts 11 are partially heat-sealed via the multiple notch portions 14.
When heat-sealing the peripheral portions of the pair of film sheet parts 11, peripheral portions of portions excluding an inlet 15 for injecting contents is heat-sealed first, and after the contents are injected, the inlet 15 is heat-sealed. The contents are, for example, in a liquid, granular, or powder form.
The pouch 10 has a ceiling portion 10a and a bottom portion 10b, and the inlet 15 is formed at the ceiling portion 10a of the pouch 10. That is, the inlet 15 is formed at an upper end portion of the pair of film sheet parts 11.
The film sheet parts 11 and the gusset sheet part 12 each include, for example, a film of a synthetic resin having thermal adhesive properties, such as polyethylene or polypropylene. Furthermore, the film sheet parts 11 and the gusset sheet part 12 may each include a layered film in which a metal layer having gas barrier properties, such as aluminum, or a paper layer having heat insulating properties and a film of a synthetic resin such as polyester are layered.
The spout 20 is made of polyethylene, polypropylene, or the like and includes a fixed portion 21 that is attached to the bag-shaped pouch 10, and a mouth portion that is provided above the fixed portion 21 and serves as a drinking spout or a pouring spout that can be opened and closed by a screw cap 22. With the fixed portion 21 sandwiched between upper edge portions of the pair of film sheet parts 11, 11, a side surface of the fixed portion 21 is heat-sealed to the upper edge portions of the pair of film sheet parts 11, 11.
The pouch container 100 includes a storage space 30 and a peripheral portion 40 in which a seal portion 50 is formed. As described above, the storage space 30 is formed when the peripheral portions of the gusset sheet part 12 and the lower peripheries of the pair of film sheet parts 11 are heat-sealed and the peripheral portions of the pair of film sheet parts 11 at the portion excluding the inlet 15 are heat-sealed.
The peripheral portion 40 is located outside the storage space 30. The peripheral portion 40 includes the seal portion 50 and an unsealed area 60.
The seal portion 50 is formed by heat-sealing the pair of film sheet parts 11 and the gusset sheet part 12 as described above. The pair of film sheet parts 11 and the gusset sheet part 12 are bonded by the seal portion 50. The seal portion 50 is an area indicated by a dotted pattern in
The unsealed area 60 is an area where the pair of film sheet parts 11 are not sealed. The unsealed area 60 has a band-like lower portion and an upper portion that expands toward the storage space 30. The band-like lower portion of the unsealed area 60 may slope further toward the side edge of the pouch 10 closer to the bottom.
The unsealed area 60 is formed to include a portion located between the first curled portion seal area 51 and the second curled portion seal area 52.
The peripheral portion 40 is provided with a first cut line portion 70 that forms a tongue portion 81 (see
The first cut line portion 70 is formed to include an upper side portion, a lower side portion, and a connecting side portion that connects end portions of the upper side portion and the lower side portion located on the storage space 30 side. The first cut line portion 70 is formed in a substantially C-shape.
More specifically, the first cut line portion 70 includes a first end portion 71, a second end portion 72, a first extending portion 75, a second extending portion 76, and a connecting portion 77. The first end portion 71 and the second end portion 72 are provided so as to face each other in an up-down direction.
The first end portion 71 is provided closer to the ceiling portion 10a of the pouch 10 than the second end portion 72. The first end portion 71 includes a first curled portion 73 curled toward the second end portion 72. The first curled portion 73 is formed in a substantially arc shape. The first curled portion 73 is curved inward.
The first end portion 71 is provided in the unsealed area 60. The first end portion 71 is sealed by the first curled portion seal area 51 formed in an island shape inside the unsealed area 60.
The second end portion 72 is provided closer to the bottom portion 10b of the pouch 10 than the first end portion 71. The second end portion 72 includes a second curled portion 74 curled toward the first end portion 71. The second curled portion 74 is formed in a substantially arc shape. The second curled portion 74 is curved inward. The second end portion 72 is provided outside the unsealed area 60. The second end portion 72 is sealed by the second curled portion seal area 52 located outside the unsealed area 60. The second curled portion seal area 52 is a part of the seal portion 50 surrounding the unsealed area 60 and is located below the unsealed area 60.
The first extending portion 75 is connected to the first end portion 71 and extends toward the storage space 30. The first extending portion 75 includes a bulging portion 75a that bulges toward the inside of the unsealed area 60. A central portion of the bulging portion 75a bulges toward the bottom portion 10b. A tongue portion 82 (see
The second extending portion 76 is connected to the second end portion 72 and extends toward the storage space 30. The second extending portion 76 is located outside the unsealed area 60 and is provided in the seal portion 50.
The connecting portion 77 connects end portions of the first extending portion 75 and the second extending portion 76 located on the storage space 30 side. The connecting portion 77 extends, for example, along part of an outer edge of the storage space 30. An upper side of the connecting portion 77 is provided inside the unsealed area 60, and a lower side of the connecting portion 77 is provided in the seal portion 50.
As illustrated in
A tip 71a of the first end portion 71 is located closer to the storage space 30 (closer to the connecting portion 77) than the fold line L1. An angle θ1 formed by the fold line L1 and a line connecting a curl center O1 of the first curled portion 73 at the tip 71a of the first end portion 71 and the tip 71a may be, for example, 90 degrees or less, about 20 degrees to 60 degrees, or about 30 degrees to 50 degrees. In this embodiment, the angle θ1 is, for example, about 40 degrees.
A tip of the second end portion 72 is located closer to the storage space 30 (closer to the connecting portion 77) than the fold line L1. An angle θ2 formed by the fold line L1 and a line connecting a curl center O2 of the second curled portion 74 at the tip 72a of the second end portion 72 and the tip 72a may be, for example, 180 degrees or less, 90 degrees or less, or about 30 degrees to 80 degrees. In this embodiment, the angle θ2 is about 50 degrees to 75 degrees, and more specifically about 67 degrees.
As illustrated in
At this time, by providing the unsealed area 60 at least between the first curled portion seal area 51 and the second curled portion seal area 52, rigidity of the fold line L1 can be reduced and the tongue portion 81 can be easily folded back. This improves usability of the pouch container 100. Further, since at least some of the area where the fold line L1 is formed is in the unsealed area, finger pain when gripping the pouch container 100 by inserting fingers into the grip hole is reduced.
In addition, by providing the bulging portion 75a in the first cut line portion 70, the tongue portion 82 located between the bulging portion 75a and the fold line L2 is also raised such that the tongue portion 82 comes into surface contact with the fingers. Therefore, the load of the pouch container 100 applied to the fingers can be dispersed by the tongue portion 82. This can prevent a cut end surface of the first cut line portion 70 from cutting into the fingers, further improving the usability of the pouch container 100.
Furthermore, since the first curled portion 73 of the first end portion 71 is sealed by the first curled portion seal area 51 and the second curled portion 74 of the second end portion 72 is sealed by the second curled portion seal area 52, strength of the first curled portion 73 and the second curled portion 74 can be ensured. This prevents the pouch container 100 from being damaged starting at the first curled portion 73 and the second curled portion 74, even when the pouch container 100 is gripped with fingers with the tongue portion 81 raised.
By setting the angle θ1 and the angle θ2 as described above, the position of the fold line L1 can be set to an appropriate position, and the strength of the film at the first end portion 71 and the strength of the film at the second end portion 72 can be further ensured. This further reduces damage to the pouch container 100.
In addition, multiple pouch containers 100 may be conveyed in a stacked state in a state before the contents are injected into the storage space 30. In general, when multiple pouch containers are conveyed in a stacked state, peeled portions at both end portions of the first cut line portions of the stacked pouch containers may get caught on each other. In such a case, when one of the stacked pouch containers is moved, force is concentrated on the caught portion and the film is ripped at both end portions of the first cut line portion.
In this embodiment, as described above, the first curled portion 73 of the first end portion 71 is sealed by the first curled portion seal area 51, and the second curled portion 74 of the second end portion 72 is sealed by the second curled portion seal area 52. Therefore, even when multiple pouch containers 100 are conveyed in a stacked state, the first end portions 71 or the second end portions 72 of the pouch containers 100 adjacent to each other are prevented from getting caught on each other. This allows one of the pouch containers 100 to be easily moved in a state where the pouch containers 100 are stacked, thereby suppressing damage to the pouch container 100 due to being caught.
Furthermore, since the first end portion 71 is sealed by the first curled portion seal area 51 formed in an island shape inside the unsealed area 60, damage to the first end portion 71 can be suppressed. In addition, by forming the first curled portion seal area 51 in an island shape, the unsealed area 60 can be made longer upward. Therefore, the tongue portion 81 can be easily folded along the fold line L1, and the load placed on the finger can be reduced when the fingers are inserted into the grip hole to grip the pouch container 100. As a result, usability of the pouch container 100 can be improved. In particular, when the contents are heavy, a large load is applied to the index finger located at the top. Therefore, by extending the unsealed area 60 upward, the unsealed area 60 comes into contact with the index finger and the load on the finger can be effectively reduced.
On the other hand, since the second end portion 72 is reliably sealed by the second curled portion seal area 52 that is provided integrally with the seal portion 50 surrounding the unsealed area 60, damage can be more reliably suppressed.
In addition, since the upper side of the connecting portion 77 is provided inside the unsealed area 60, when gripping the pouch container 110 by inserting the fingers into the grip hole, the unsealed area 60 comes into contact with the index finger in a similar way as described above, thus reducing the load on the finger. This also improves the usability of the pouch container 100. Further, since the lower side of the connecting portion 77 is provided in the seal portion 50, the pair of front and back film sheet parts 11 are integrated. This prevents turning up and damage, thereby improving ease of handling.
Referring to
Note that the microjoint portions 91 are minute uncut areas that locally connect the first cut line portion 70 and are indicated by solid lines in
All of the multiple microjoint portions 91 are located closer to a storage space 30 than a fold line L1. The multiple microjoint portions 91 are provided at a central portion of a bulging portion 75a, in the vicinity of both end portions of the bulging portion 75a, in the vicinity of a tip 72a of a second end portion 72, in the vicinity of a boundary portion between the second end portion 72 and a second extending portion 76, and at a connecting portion 77. The microjoint portions 91 are formed by not partially cutting a pair of film sheet parts 11 when forming the first cut line portion 70 in the pair of film sheet parts 11 using a cutting blade that is slightly chipped at portions corresponding to the microjoint portions 91.
When a tongue portion 81 is raised and the pouch container 100 is gripped with fingers, the load of the pouch container 100 is easily transferred to the microjoint portions 91 formed in the first end portion 71 and the second end portion 72. By forming the microjoint portions 91 at the first end portion 71 and the second end portion 72 inward of the fold line L1, cracks are prevented from running toward an outer edge of the pouch container 100 when a load is applied.
By having the configuration described above, the pouch container 100A according to the second embodiment can obtain substantially the same effects as those of the first embodiment. In addition, by providing the multiple microjoint portions 91, the film sheet parts 11 can be prevented from opening at a portion of the first cut line portion 70 provided in an unsealed area 60 and the tongue portion 81 can be prevented from inadvertently moving at a portion of the first cut line portion 70 provided in the seal portion 50. Further, when the tongue portion 81 is raised to grip the pouch container 100A, the multiple microjoint portions 91 can be easily broken up.

As illustrated in
The second cut line portion CL is formed in a seal portion 50 located closer to a ceiling portion 10a than a first extending portion 75. The second cut line portion CL is located closer to the ceiling portion 10a than the first extending portion 75 and faces the first extending portion 75 and a first end portion 71 in a direction in which a bottom portion 10b and the ceiling portion 10a are aligned.
The second cut line portion CL includes a first portion CLa extending in a direction in which the first extending portion 75 extends, and second portions CLb extending from both ends of the first portion CLa toward the ceiling portion 10a. In this embodiment, a case is illustrated in which the first portion CLa is provided bulging toward the ceiling portion 10a, but the first portion CLa may be provided linearly.
By providing the second cut line portion CL, a bridge portion 95 is formed in a peripheral portion 40, between the second cut line portion CL and both the first extending portion 75 and the first end portion 71. An upper end of the bridge portion 95 is defined by the second cut line portion CL. The upper end of the bridge portion 95 includes a bulging portion 95b that bulges toward the ceiling portion 10a. A lower end of the bridge portion 95 is defined by the first extending portion 75 and the first end portion 71. The lower end of the bridge portion 95 includes a bulging portion 95a that bulges toward the bottom portion 10b.
As illustrated in
At this time, the load of the pouch container 100I and the contents stored therein is applied to the hand gripping the pouch container 100I. More specifically, the load is applied to the index finger via the bridge portion 95.
Here, in the pouch container 100I according to the tenth embodiment, as described above, the upper end of the bridge portion 95 is defined by the first portion CLa and the second portions CLb extending upward from both ends of the first portion CLa.
Therefore, the second portions CLb extending in the application direction of the load (i.e., the direction in which the ceiling portion 10a and the bottom portion 10b are aligned) promotes torsional deformation of the bridge portion 95, causing the bridge portion 95 to curve greatly along the index finger. This increases the contact area between the bridge portion 95 and the index finger, and the load applied to the index finger can be greatly reduced.
Thus, in the pouch container 100I according to the tenth embodiment, the load applied to the index finger can be reduced further than that in the pouch container 100C according to the fourth embodiment.
As illustrated in
With the above configuration, the pouch container 100J according to the eleventh embodiment can further reduce the load applied to the index finger in a similar way as described above.
As illustrated in
With the above configuration, the pouch container 100K according to the twelfth embodiment can further reduce the load applied to the index finger in a similar way as described above.
As illustrated in
With the above configuration, the pouch container 100L according to the thirteenth embodiment can further reduce the load applied to the index finger in a similar way as described above.
