Description

The present invention relates to packages.

Conventionally, packages capable of containing contents such as food have been proposed. As such a package, for example, Japanese Patent Application Laid-Open No. 2006-96388 (Patent Document 1) describes a standing pouch that can stand on its own while being filled with contents.

JP-A-2006-96388

In the standing pouch described in the above publication, an opening for taking out the contents is formed in the intended opening portion. Specifically, an opening is formed by cutting the top of the standing pouch along the opening cut. The aperture is constituted by the gap between the front film and the back film before the aperture is formed. The opening is widened by widening the gap between the front film and the back film after the opening is formed. Even in this case, the opening narrows again as the front and back films try to return to their original shapes. Therefore, the state in which the opening is widened cannot be maintained. Therefore, it is difficult to take out the contents from the opening.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and an object of the present invention is to provide a packaging body that can maintain the state in which the opening is widened when the intended opening portion is opened.

The package of the present invention has a first side film, a second side film and a bottom film. The second side film faces the first side film. A bottom film is arranged between the first side film and the second side film. The package includes a peripheral portion and a storage portion. The peripheral edge portion is arranged on the periphery of each other of the first side film and the second side film. The storage part is surrounded by the peripheral part. The peripheral portion includes a peripheral edge seal portion, a bottom seal portion, and a portion to be sealed. The peripheral edge seal part seals a part of the peripheral edges of the first side film and the second side film. The bottom seal portion seals each of the first side film and the second side film and the bottom film. The portion to be sealed communicates the outside of the package with the storage portion in a state in which the other peripheral edges of the first side film and the second side film are not sealed. The first side film includes a planned opening portion for opening so as to allow communication between the outside of the package and the storage portion. The peripheral seal portion includes a top seal portion arranged on the side opposite to the bottom seal portion with respect to the intended opening portion. The top seal portion includes a body portion provided with a slit and a hook portion cantilevered by the body portion. The hook portion has one end and the other end, a trunk portion connected to the body portion at one end, and a head portion connected to the trunk portion at the other end. The head portion protrudes from the body portion in the vertical direction in which the bottom seal portion and the top seal portion face each other. In the vertical direction, the dimension of the slit is larger than the dimension of the trunk and smaller than the dimension of the head. The hook portion is cantilevered on the body portion so as to protrude from one end of the body portion in the direction opposite to the slit. The hook portion can be engaged with the body portion in a state where the head is inserted into the slit by curving the body portion so as to protrude from the first side film toward the second side film. With the hook portion engaged with the body portion, any portion of the body portion extending along the width direction of the package is arranged to overlap with the center line in the width direction of the package. The second side film is not provided with a planned opening portion. The planned opening portion is arranged so as to extend in the width direction between both side ends in the width direction of the package.

According to the package of the present invention, when the planned opening portion is opened, the hook portion is curved so that the main body portion protrudes in the direction from the first side film toward the second side film. By engaging the hook portion with the body portion in a state in which the opening is inserted, the state in which the opening is widened can be maintained.

The slit 61a penetrates the body portion 61 . The slit 61 a extends along the vertical direction HD of the package 1 . The slit 61a is provided linearly. The slit 61a and the hook portion 62 may be formed by punching. A gap may be provided between the outer edge of the hook portion 62 and the body portion 61 . A portion of the top seal portion 60 is cut and raised from the body portion 61 to form a hook portion 62 . The planned opening portion 50 is arranged between the slit 61 a and the hook portion 62 and the bottom seal portion 22 in the vertical direction HD of the package 1 .

The hook portion 62 is cantilevered on the body portion 61 . That is, the hook portion 62 has a cantilever support beam structure. The base of the hook portion 62 constitutes the fixed end of the cantilever support beam structure, and the tip of the hook portion 62 constitutes the free end of the cantilever support beam structure. In this embodiment, the hook portion 62 has an arrow shape as a whole. The hook portion 62 has a body portion 62a and a head portion 62b. The body portion 62 a extends along the width direction WD of the package 1 . The body portion 62 a has one end 621 and the other end 622 . The body portion 62 a is connected to the body portion 61 at one end 621 . In the present embodiment, the body portion 62a is configured such that the width in the vertical direction HD increases from the other end 622 toward the one end 621 .

The head 62b is connected at the other end 622 to the body 62a. The head portion 62b protrudes from the body portion 62a in the vertical direction HD in which the bottom seal portion 22 and the top seal portion 60 face each other. The angle θ between the outer edge of the portion of the head 62b projecting from the body 62a on the side of the body 62a and the imaginary straight line extending in the width direction WD of the package 1 through the other end 622 of the body 62a is a right angle. (90 degrees) or less. This makes it easy to maintain the state in which the hook portion 62 is engaged with the main body portion 61 .

In the vertical direction HD, the dimension L1 of the slit 61a is larger than the dimension L2 of the body portion 62a and smaller than the dimension L3 of the head portion 62b. The dimension L2 of the body portion 62a is the dimension of the portion connected to the head portion 62b. A dimension L1 of the slit 61a is, for example, 4 mm or more and 10 mm or less. A dimension L2 of the body portion 62a is, for example, 3 mm or more and 9 mm or less. A dimension L3 of the head 62b is, for example, 5 mm or more and 11 mm or less.

The hook portion 62 is cantilevered on the body portion 61 so as to protrude from the one end 621 of the body portion 62a on the side opposite to the slit 61a. In the present embodiment, before the hook portion 62 is engaged with the body portion 61, the hook portion 62 is configured to protrude toward the side opposite to the slit 61a. Further, in a state after the hook portion 62 is engaged with the body portion 61, the hook portion 62 is configured to protrude toward the slit 61a. The head 62b has a taper 62b2 in which the width in the vertical direction HD decreases toward the tip 62b1 of the head 62b. That is, the head 62b is configured to taper toward the tip 62b1 of the head 62b. In this embodiment, the head 62b has a triangular shape with the vertex located at the tip 62b1 of the head 62b.

Next, with reference to FIG. 4, the configuration of the package 1 in a state where the content 10 is stored in the storage portion 30 will be described. In this state, package 1 further comprises content 10 stored in storage portion 30 . In the state where the content 10 is stored in the storage portion 30 , the other portions of the peripheral edges of the first side film 11 and the second side film 12 are sealed in the sealing portion 23 . Specifically, the first side film 11 and the second side film 12 may be sealed to each other by heat welding at the sealing portion 23 . Thereby, all peripheral edge portions 20 are sealed. Therefore, when the contents 10 are stored in the storage portion 30, the storage portion 30 is sealed.

Next, with reference to FIG. 5, the configuration of the package 1 in a state where the planned opening portion 50 is opened will be described. In this state, the package 1 further includes the content 10 stored in the storage portion 30, as in the state shown in FIG. In addition, when the contents 10 are stored in the storage section 30, all the peripheral edges 20 are sealed. Furthermore, the planned opening portion 50 is opened so as to allow communication between the outside of the package 1 and the storage portion 30 . Specifically, the intended opening portion 50 may be opened by, for example, removing a band-shaped portion of the first side film 11 surrounded by a perforation structure or a half-cut structure.

Since the first side film 11 and the second side film 12 are sealed to each other at the sealing portion 23 provided at the upper end of the package 1, the first side film 11 is less likely to bend than the first side film 11 alone. Therefore, when the intended opening portion 50 is opened, the portion of the first side film 11 forming the opening on the bottom film 13 side is bent, thereby widening the opening.

Further, after the planned opening portion 50 is opened, the body portion 61 protrudes from the first side film 11 toward the second side film 12 as indicated by the arrow A in FIG. 5 by the user of the package 1. It is deformed into a curved state to do. As a result, the hook portion 62 from the body portion 61 stands up in the direction from the second side film 12 toward the first side film 11 . Specifically, the hook portion 62 stands up so as to warp toward the slit 61a. Also, the distance between the hook portion 62 and the slit 61a is shortened. Therefore, when the hook portion 62 reaches the slit 61a, the head portion 62b of the hook portion 62 can be inserted into the slit 61a from the first side film 11 toward the second side film 12. As shown in FIG.

In the vertical direction HD, the dimension L1 of the slit 61a is larger than the dimension L2 of the body portion 62a and smaller than the dimension L3 of the head portion 62b. Since it is sealed, it can be elastically deformed. The head 62b of the hook portion 62 passes through the slit 61a in a deformed state in which the dimension L3 of the head 62b is smaller than the dimension L1 of the slit 61a, and after passing through the slit 61a, the dimension L3 of the head 62b becomes smaller than the dimension L1 of the slit 61a. will also grow. Therefore, the head portion 62b of the hook portion 62 is engaged with the second side film 12 while being inserted into the slit 61a. In this manner, the hook portion 62 engages with the body portion 61 . At this time, since the head portion 62b protrudes in the vertical direction HD more than the body portion 62a, the hook portion 62 is locked to the main body portion 61 while the hook portion 62 is engaged with the main body portion 61.

At this time, as indicated by an arrow B in FIG. 5, the sealing portion 23 provided at the upper end of the package 1 is deformed such that both ends in the width direction WD of the package 1 approach each other. As a result, as indicated by arrow C in FIG. 5 , the portion of the first side film 11 forming the opening that is closer to the bottom film 13 curves in the direction opposite to the direction in which the main body 61 curves. In this way the opening is widened.

By keeping the hook portion 62 engaged with the main body portion 61 in a state in which the opening is widened, the hook portion 62 is curved so as to protrude from the first side film 11 toward the second side film 12 . The shape of the main body portion 61 is maintained. In addition, the portion of the first side film 11 forming the opening that is on the side of the bottom film 13 is held in a curved state opposite to the direction in which the body portion 61 curves. In this manner, the state in which the opening is widened is maintained.

With the hook portion 62 engaged with the body portion 61, the slit is formed so that the left and right bisector of the package 1 and the left and right bisector of the body portion 62a overlap in the width direction WD of the package 1. 61a and the hook part 62 may be set. In other words, the center line CL of the package 1 in the width direction WD may overlap the center line of the body portion 62a in the width direction WD. This makes it possible to widen the opening symmetrically in the width direction WD. Note that any one of the body portions 62 a may be arranged so as to overlap the center line CL in the width direction WD of the package 1 . This also facilitates widening the opening.

Next, the effects of the package according to this embodiment will be described.
According to the package 1 of the present embodiment, the slit 61a and the hook portion 62 are arranged on the side opposite to the bottom seal portion 22 with respect to the portion to be opened 50 . The hook portion 62 is cantilevered on the body portion 61 so as to protrude from the one end 621 of the body portion 62a in the direction opposite to the slit 61a. The hook portion 62 is bent so that the main portion 61 protrudes from the first side film 11 toward the second side film 12, and the hook portion 62 becomes the main portion with the head portion 62b inserted into the slit 61a. 61 is engageable. Therefore, when the scheduled opening portion 50 is opened so as to communicate the outside of the package 1 and the storage portion 30 , the first side film 11 and the second side film 12 are placed in the first direction in accordance with the shape of the main body portion 61 . It can be held in a curved state so as to protrude from the side film 11 toward the second side film 12 . Then, the portion of the first side film 11 forming the opening, which is on the bottom film 13 side, can be held in a curved state opposite to the direction in which the body portion 61 curves. In this manner, when the planned opening portion 50 is opened, the state in which the opening is widened can be maintained. Therefore, it becomes easy to take out the contents 10 from the opening. In addition, it becomes possible to easily take the tableware into and out of the storage section 30 .

As a result, the hook portion 62 stands up from the body portion 61 . Therefore, the erected hook portion 62 can be inserted into the slit 61 a while being pressed by the user's finger and engaged with the main body portion 61 . That is, the hook portion 62 can be inserted into the slit 61a and engaged with the main body portion 61 with one touch. Therefore, the hook portion 62 can be engaged with the main body portion 61 with one hand. Further, since the hook portion 62 is inserted into the slit 61a in a warped state, the hook portion 62 presses the body portion 61 with a force (restoring force) that causes the hook portion 62 to return to its original shape. This promotes engagement between the hook portion 62 and the body portion 61 .

According to the package 1 of the present embodiment, the head portion 62b of the body portion 62a has a taper 62b2 in which the width in the vertical direction HD decreases toward the tip 62b1 of the head portion 62b. Therefore, by inserting the hook portion 62 into the slit 61a from the tip 62b1 of the head portion 62b, the hook portion 62 can be easily inserted into the slit 61a.

According to the package 1 according to the present embodiment, when the content 10 is stored in the storage portion 30 , the portion to be sealed 23 has the edges other than the edges of the first side film 11 and the second side film 12 . part is sealed. Therefore, in the state where the content 10 is stored in the storage portion 30, the storage portion 30 can be sealed.

According to the package 1 according to the present embodiment, the planned opening portion 50 opens so as to allow the outside of the package 1 and the storage portion 30 to communicate with each other.

Each of the first side film, second side film and bottom film was laminated from the side to be sealed with a layer of linear low density polyethylene (LLDPE), nylon (NY), polyethylene terephthalate (PET) from the side to be sealed. It has a three-layer structure. The thickness of each layer is 100 μm for linear low density polyethylene (LLDPE), 25 μm for nylon (NY), and 12 μm for polyethylene terephthalate (PET). Each package of Examples 1 to 3 and Comparative Examples 1 and 2 has a tapered shape in which the dimension in the width direction of the package increases from the lower end to the upper end in the vertical direction. Contents are stored in the storage portion of each package of Examples 1-3 and Comparative Examples 1-2. Specifically, the contents are side dishes. Each of the packages of Examples 1-3 and Comparative Examples 1-2 had an overall length in the vertical direction of 140 mm and an overall width in the width direction of 150 mm.

In each of the packages of Examples 1-3, the first side film and the second side film are sealed to each other at all peripheral edges of the package. In each of the packages of Examples 1 to 3, the slit and hook portions are arranged between the planned opening portion and the upper end of the package. The planned opening portion is arranged on the side surface of the package. For each of the packages of Examples 1 to 3, a comparative sensory evaluation was performed in a state in which the scheduled opening portion was opened so as to allow communication between the outside of the package and the storage portion.

The package of Example 1 has the same configuration as that of Embodiment 2 described above. In the package of Example 1, the hook portion has an arrow shape. The package of Example 2 has the same configuration as that of Modification 1 of Embodiment 1 described above. In the package of Example 2, the tip of the hook portion has an elliptical shape. The package of Example 3 has the same configuration as that of Modification 2 of Embodiment 1 described above. In the package of Example 3, the tip of the hook portion has a rhombic shape. The package of Example 4 has the same configuration as that of Modification 3 of Embodiment 1 described above. In the package of Example 4, compared with Example 1, the dimension of the hook portion in the width direction of the package is longer.

The package of Comparative Example 1 differs from those of Examples 1 to 3 in that it does not have slits and hooks. For the package of Comparative Example 1, a comparative sensory evaluation was performed in a state in which the scheduled opening portion was opened so as to allow communication between the outside of the package and the storage portion.

The package of Comparative Example 2 differs from those of Examples 1 to 3 in that it does not have slits and hook portions and that an opening is provided at the upper end of the package. For the package of Comparative Example 1, a comparative sensory evaluation was performed in a state in which the upper end of the package was opened so as to communicate the outside of the package with the storage portion.

Table 1 shows the results of the comparative sensory evaluation. As shown in Table 1, in the comparative sensory evaluation, the ease of opening, effectiveness of the hook portion, ease of disposal, ease of taking out the contents, and overall evaluation were evaluated. The openability is the easiness of opening the portion to be opened. The effect of the hook portion is the ease with which the opening can be held in a state where the main body portion is curved and the hook portion is engaged with the slit. Ease of disposal is the ease of disposal of the package. The ease of taking out the contents is the ease of taking out the contents. Comprehensive evaluation is the average value of the openability, effectiveness of the hook portion, ease of disposal, and ease of taking out the contents. These evaluations were evaluated on a 5-point scale using numerals 1-5. Specifically, it was evaluated as 1 for the worst, 5 for the best, and 3 for the middle. Five evaluators were used. The numerical value of evaluation was made into the average value of five persons.

As a result of comparative sensory evaluation, each of Examples 1 to 3 was evaluated higher than each of Comparative Examples 1 and 2 in terms of the opening property and effectiveness of the hook portion. Therefore, it was found that each of Examples 1 to 3 was able to maintain the state in which the opening was widened compared to each of Comparative Examples 1 and 2. In addition, each of Examples 1 to 3 was evaluated higher than each of Comparative Examples 1 and 2 in terms of ease of taking out the contents. Therefore, in each of Examples 1-3, it was found that it was easier to take out the contents from the opening than in each of Comparative Examples 1-2. It should be noted that each of Examples 1 to 3 had a higher overall evaluation than each of Comparative Examples 1 and 2.
