<Constitution of Support>
FIG. 1 is a perspective view of the support according to an embodiment of the present disclosure from the opening side. FIG. 2 is a top view of the support according to an embodiment of the present disclosure. FIG. 3 is a perspective view of the support according to an embodiment of the present disclosure from below. As shown in FIGS. 1 to 3, the support 100 according to an embodiment of the present disclosure forms a cylindrical sleeve with a front plate 1 and a rear plate 2 (also indicated as a rear plate first portion 2a and a rear plate second portion 2b in FIGS. 1 and 2). Furthermore, a bottom portion 9 and first locking portions 3a, 3b, 4a, and 4b are located so as to close the lower side of the sleeve. The bottom portion 9 is composed of a first bottom plate 7 connected to the front plate 1 and a second bottom plate 8 connected to the rear plate 2. The bottom portion 9 is fixed as a bottom surface by being locked between the first locking portions 3a, 3b, 4a, and 4b and the second locking portions 5a, 5b, 6a, and 6b.

The bag is inserted between the front panel 1 and the back panel 2 from the opening on the opposite side of the bottom 9, and the bag is held by the bottom 9. Then, by placing a support 100 with the bottom 9 facing downward, the bag can be supported to stand upright.

Figure 4 is a diagram showing a support creation sheet, which is a sheet for creating a support according to this embodiment. Figure 4 is also a development view of the support according to this embodiment. The support creation sheet 100a, which is the support 100 developed, is formed by punching out a sheet of paperboard such as manila board, cardboard, cardboard, or craft cardboard having a predetermined basis weight. The support creation sheet 100a may also be formed from a resin plate.

As shown in FIG. 4, the support-making sheet 100a has first fold lines f1 and f2, second fold lines g1 to g4, third fold lines h1 and h2, fourth fold lines i1 to i4, fifth fold lines j1 and j2, and sixth fold line k. In the support-making sheet 100a, the back panel first portion 2a and the back panel second portion 2b are connected to both sides of the front panel 1. Specifically, the front panel 1 is connected to the back panel first portion 2a via the first fold line f1, and connected to the back panel second portion 2b via the first fold line f2. The back panel first portion 2a and the back panel second portion 2b are folded from the first fold lines f1 and f2, respectively, and then bonded together at the adhesive portion S1 to form the back panel 2. Therefore, the front panel 1 and the back panel 2 form a cylindrical sleeve.

The first bottom plate 7 is connected to the lower part of the front panel 1 via the fifth fold line j1. The first bottom plate 7 is divided into a first bottom plate first portion 7a and a first bottom plate second portion 7b by the sixth fold line k. The first bottom plate first portion 7a of the first bottom plate 7 is connected to the front panel 1 via the fifth fold line j1.

The second bottom plate 8 is connected to the lower part of the second part 2b of the rear panel via the fifth fold line j2. The second bottom plate 8 is later attached to the second part 7b of the first bottom panel by the adhesive part S2. The first bottom plate 7 and the second bottom plate 8 then form the bottom part 9. The bottom part 9 connects the front panel 1 and the rear panel 2 below the support 100.

The first bottom plate 7 is located at the center of the front plate 1 in the longitudinal direction of the support creation sheet 100a. The center of the front plate 1 in the longitudinal direction of the support creation sheet 100a is the middle position between the first fold line f1 and the first fold line f2. In this embodiment, the middle position of the first bottom plate 7 and the middle position of the first fold line f1 and the first fold line f2 in the longitudinal direction of the support creation sheet 100a coincide with each other. In the longitudinal direction of the support creation sheet 100a, the middle position of the first bottom plate 7 is the middle position between two end points P2, P2 (see FIG. 4) described later. In addition, the second bottom plate 8 is formed from the end of the back plate second portion 2b on the opposite side to the first fold line f2 in the longitudinal direction of the support creation sheet 100a. In this embodiment, the second bottom plate 8 is not connected to the back plate first portion 2a. As shown in Figures 1 to 3, when the support 100 is formed, the first bottom plate 7 is located at the center of the front panel 1 and the second bottom plate 8 is located at the center of the back panel 2 in the left-right direction (the direction connecting the first fold line f1 and the first fold line f2). In this embodiment, in a state in which the back panel 2 is formed by connecting the back panel first portion 2a and the back panel second portion 2b, the first bottom plate 7 and the second bottom plate 8 are provided at positions that coincide with each other in the left-right direction.

As shown in FIG. 4, the first part 3a of the locking portion is connected to the lower part of the front panel 1 via the second fold line g2. Similarly, the first part 3b of the locking portion is connected to the lower part of the back panel 1 via the second fold line g1. Furthermore, the second part 5a of the locking portion is connected to the lower part of the first part 3a via the fourth fold line i2. Similarly, the second part 5b of the locking portion is connected to the lower part of the first part 3b via the fourth fold line i1. The second part 5a of the locking portion and the second part 5b of the locking portion are connected to the third fold line h1. The first fold line f1 and the third fold line h1 are on the same straight line, and the end point P1 is the boundary point. This end point P1 is also the common end point of the second fold lines g1, g2 and the fourth fold lines i1, i2.

A recess is formed on the outer edge of the locking portion. Specifically, a recess o1 is formed between the outer edge of the locking portion first portion 3a and the outer edge of the locking portion second portion 5a, and a recess o2 is formed between the outer edge of the locking portion first portion 3b and the outer edge of the locking portion second portion 5b. The recess o1 is located at the tip of the fourth fold line i2, and the recess o2 is located at the tip of the fourth fold line i1. In this embodiment, the locking portion first portion 3a and the locking portion first portion 3b have mutually symmetrical shapes and are positioned line-symmetrical to each other across the third fold line h1. Also, the locking portion second portion 5a and the locking portion second portion 5b have mutually symmetrical shapes and are positioned line-symmetrical to each other across the third fold line h1.

The first portion 4a of the locking portion is connected to the lower portion of the front panel 1 near the first fold line f2 via the second fold line g3, as in the vicinity of the first fold line f1. Similarly, the first portion 4b of the locking portion is connected to the lower portion of the second portion 2b of the back panel via the second fold line g4. Furthermore, the second portion 6a of the locking portion is connected to the lower portion of the first portion 4a via the fourth fold line i3. Similarly, the second portion 6b of the locking portion is connected to the lower portion of the first portion 4b via the fourth fold line i4. The second portion 6a of the locking portion and the second portion 6b of the locking portion are connected to the third fold line h2. The first fold line f2 and the third fold line h2 are on the same straight line, and the end point P1 is the boundary point. This end point P1 is also the common end point of the second fold lines g3, g4 and the fourth fold lines i3, i4. In this way, the locking portions are connected to the front panel 1, the rear panel first portion 2a, and the rear panel second portion 2b via the second fold lines g1 to g4, spanning from the front panel 1 to the rear panel first portion 2a and from the front panel 1 to the rear panel second portion 2b, respectively.

Similar to the vicinity of the first fold line f1, a recess is also formed on the outer edge of the locking portion near the first fold line f2. Specifically, a recess o3 is formed between the outer edge of the locking portion first part 4a and the outer edge of the locking portion second part 6a, and a recess o4 is formed between the outer edge of the locking portion first part 4b and the outer edge of the locking portion second part 6b. The recess o3 is located at the tip of the fourth fold line i3, and the recess o4 is located at the tip of the fourth fold line i4. In this embodiment, the locking portion first part 4a and the locking portion first part 4b have mutually symmetrical shapes and are positioned line-symmetrical to each other across the third fold line h2. Also, the locking portion second part 6a and the locking portion second part 6b have mutually symmetrical shapes and are positioned line-symmetrical to each other across the third fold line h2.

In this embodiment, the locking portion near the first fold line f1 and the locking portion near the first fold line f2 have the same shape. In the completed support, these locking portions are positioned so that they face each other across the bottom 9.

A total of 15 fold lines are formed on the support-making sheet 100a: the first fold lines f1, f2, the second fold lines g1-g4, the third fold lines h1, h2, the fourth fold lines i1-i4, the fifth fold lines j1, j2, and the sixth fold line k. In the example of FIG. 4, the first fold lines f1 and f2 are mountain folds. In this case, when the support 100 is formed, the third fold lines h1 and h2 are valley folds, and the second fold lines g1-g4, the fourth fold lines i1-i4, the fifth fold lines j1, j2, and the sixth fold line k are all mountain folds.

The second fold lines g1 to g4 and the fifth fold lines j1 and j2 that divide the front panel 1, the back panel 2, the bottom 9, and the locking portion are generally formed along the longitudinal direction (left and right direction in FIG. 4) of the support creation sheet 100a. However, in this embodiment, the fifth fold line j1 that divides the front panel 1 and the first bottom panel first portion 7a, and the fifth fold line j2 that divides the back panel 2 (back panel second portion 2b) and the second bottom panel 8 are curved to be slightly convex toward the front panel 1 and the back panel 2. As shown in FIG. 4, the maximum length of the support creation sheet 100a in the longitudinal direction is a (mm), and the maximum length of the support creation sheet 100a in the lateral direction is b (mm). As an example, when a = 342 (mm) and b = 134 (mm), the radius of curvature of the fifth fold lines j1 and j2 is 229.65 mm. At this time, the distance between the center of the fifth fold line j1 and both ends P2, P2 in the short direction of the support creation sheet 100a is 3 mm. The distance between the center of the fifth fold line j2 and both ends P2, P2 in the short direction of the support creation sheet 100a (the vertical direction in FIG. 4) is also 3 mm. In this way, the fifth fold line j1 that divides the front panel 1 and the first bottom panel 7, and the fifth fold line j2 that divides the back panel 2 and the second bottom panel 8 are curved slightly convex toward the front panel 1 and the back panel 2, making it easier to fold and form a stable bottom 9 than if they were straight.

As described above, one end point of the second fold lines g1, g2 and the fourth fold lines i1, i2 are all at the end point P1, which is the boundary point between the first fold line f1 and the third fold line h1. This end point P1 is at the same position as the midpoint of the fifth fold lines j1, j2 in the short direction of the support body creating sheet 100a, which is the direction along the first fold line f1. Therefore, if the distance between the center of the fifth fold line j1 and both ends P2, P2 in the short direction of the support body creating sheet 100a is 3 mm, the distance between both ends P2, P2 of the fifth fold line j1 and the end point P1 in the short direction of the support body creating sheet 100a is also 3 mm.

In this embodiment, the second fold lines g1 to g4 that separate the front panel 1, rear panel 2, and the locking portion are curved and slightly convex toward the front panel 1 and rear panel 2. As an example, when the maximum length a of the support creation sheet 100a in the longitudinal direction is 342 (mm) and the maximum length b in the lateral direction is 134 (mm), the radius of curvature of the second fold lines g1 to g4 is 539.2 mm. In this way, the second fold lines g1 to g4 that separate the front panel 1, rear panel 2, and the locking portion are curved and slightly convex toward the front panel 1 and rear panel 2, making it easier to fold and form the locking portion than if they were straight.

Furthermore, the second fold line g1 and the fourth fold line i1, and the second fold line g2 and the fourth fold line i2 are formed to be line-symmetrical with respect to the third fold line h1 so that the engaging portions have symmetrical shapes with respect to each other across the third fold line h1. Similarly, the second fold line g3 and the fourth fold line i3, and the second fold line g4 and the fourth fold line i4 are formed to be line-symmetrical with respect to the third fold line h2 so that the engaging portions have symmetrical shapes with respect to each other across the third fold line h2.

The first fold lines f1, f2, the second fold lines g1-g4, the third fold lines h1, h2, the fourth fold lines i1-i4, the fifth fold lines j1, j2, and the sixth fold line k may be processed to make them easy to fold, or may be imaginary lines that are not actually processed. In reality, a thick cardboard is used as the support creation sheet 100a, so it is preferable that they are processed to make them easy to fold. In this embodiment, the first fold lines f1, f2, the fourth fold lines i1-i4, the fifth fold lines j1, j2, and the sixth fold line k, which are folded only in one direction, are pressed creases. In addition, in the process of forming the support 100, the second fold lines g1-g4 and the third fold lines h1, h2, which are folded in both directions, are perforated in conjunction with the pressed creases.

A cross-hatched adhesive portion S1 is formed near the end of the first portion 2a of the back panel opposite the first fold line f1. The adhesive portion S1 is formed to extend in the short direction of the support member creation sheet 100a (the vertical direction in FIG. 4). The adhesive portion S1 formed on the outer surface of the first portion 2a of the back panel is later adhered to the inner surface of the second portion 2b of the back panel to form the back panel 2.

A cross-hatched adhesive portion S2 is formed near the end of the first bottom plate second portion 7b opposite the sixth fold line k. The adhesive portion S2 is formed to extend in the longitudinal direction (left-right direction in FIG. 4) of the support body creating sheet 100a. The adhesive portion S2 formed on the outer surface side of the first bottom plate second portion 7b is later adhered to the inner surface side of the second bottom plate 8 to form the bottom 9.

<Preparation of Support 100>
The support 100 is created from the state of the support creation sheet 100a as shown in FIG. 4. The specific creation may be performed manually or by machine processing. First, from the state shown in FIG. 4, the first fold lines f1 and f2 are mountain-folded. At this time, the third fold lines h1 and h2 on the same straight line are also mountain-folded. Then, when the first portion 2a of the back panel is folded at the first fold line f1 and the second portion 2b of the back panel is folded at the first fold line f2 in order, a part of the inner surface of the second portion 2b of the back panel overlaps with the adhesive portion S1 formed on the outer surface of the first portion 2a of the back panel. Then, the first portion 2a of the back panel and the second portion 2b of the back panel are bonded to form the back panel 2. As a result, as shown in FIG. 5 and FIG. 6, the front panel 1 and the back panel 2 face each other to form a cylindrical state. FIG. 5 shows the state as seen from the front panel 1 side. FIG. 6 shows the state as seen from the back panel 2 side.

Next, the ends where the first fold lines f1 and f2 are located are pushed inward to bend the front panel 1 and back panel 2, and the fifth fold lines j1 and j2 are mountain folded (as viewed from FIG. 5). Then, a part of the inner surface of the second bottom panel 8 is overlapped with the adhesive portion S2 formed on the outer surface of the first bottom panel second portion 7b. The first bottom panel second portion 7b and the second bottom panel 8 are then adhered to each other to form the bottom portion 9. As a result, the front panel 1 and back panel 2 are connected by the bottom portion 9, as shown in FIG. 7. FIG. 7 is a top view of the support in the process of being created.

Next, the ends where the third fold lines h1 and h2 are located are pushed inward. Then, the fourth fold lines i1 to i4 are folded in a mountain fold, and the second fold lines g1 to g4 are folded in a valley fold. If the third fold lines h1 and h2 are further pushed inward, the third fold lines h1 and h2 are folded in a valley fold. Then, the second engaging portions 5a and 5b enter the inside between the first engaging portions 3a and 3b, and the second engaging portions 6a and 6b enter the inside between the first engaging portions 4a and 4b. The state at this time is shown in FIG. 8. FIG. 8 shows the state as seen from the front panel 1 side. At this point, if the sixth fold line k is folded so that the front panel 1 and the back panel 2 come into contact, the state shown in FIG. 8 will be obtained. At this time, the second locking parts 5a and 5b are overlapped on the inside of the first locking parts 3a and 3b, and the second locking parts 6a and 6b are overlapped on the first locking parts 4a and 4b.

From the state shown in FIG. 8, the sixth fold line k is pushed upward along with the fourth fold lines i1 to i4. That is, it is pushed into the cylindrical interior formed by the front panel 1 and the back panel 2. Then, the bottom 9, the first engaging portion parts 3a, 3b, and the first engaging portion parts 4a, 4b are adjusted to be in positions that form the bottom surface. The bottom 9 is pushed to a position where the first bottom panel first part 7a and the first bottom panel second part 7b form a single surface. The first engaging portion parts 3a, 3b are also pushed to a position where they form a single surface. Furthermore, the first engaging portion parts 4a, 4b are also pushed to a position where they form a single surface. At this time, the bottom 9 is adjusted to be located in the recesses o1, o2 formed in the first engaging portion parts 3a, 3b, and the recesses o3, o4 formed in the first engaging portion parts 4a, 4b. By adjusting in this way, one end of the bottom 9 is sandwiched between the first locking portion 3a and the second locking portion 5a, and between the first locking portion 3b and the second locking portion 5b. Furthermore, the other end of the bottom 9 is sandwiched between the first locking portion 4a and the second locking portion 6a, and between the first locking portion 4b and the second locking portion 6b.

The bottom 9 can be fixed by sandwiching each end of the bottom 9 between the first locking portion 4a and the second locking portion 6a, and between the first locking portion 4b and the second locking portion 6b. To do this, first, the distance from the end point P1 to the recess o must be shorter than the shortest distance between the end point P1 and the bottom 9. Furthermore, the first locking portion and the second locking portion having the end point P1 must have a point where the distance from the end point P1 is longer than the shortest distance between the end point P1 and the bottom 9. If the first locking portion and the second locking portion satisfy such conditions, each end of the bottom 9 can be sandwiched between the first locking portion 4a and the second locking portion 6a, and between the first locking portion 4b and the second locking portion 6b. By sandwiching the bottom 9 between the two locking parts from both sides, the bottom 9 and the first locking parts 3a, 3b, 4a, and 4b can be made into a single bottom surface, completing the support 100 according to this embodiment. Figure 9 is a view of the support 100 in its completed state from the front panel 1 side. Figures 1 to 3 are a perspective view from the opening side, a top view, and a perspective view from below of the support 100 in its completed state, respectively.

As shown in FIG. 2, when the inside sandwiched between the front panel 1 and the back panel 2 is viewed from above the support 100, it can be seen that both open ends of the bottom 9 are located above parts of the first engaging portions 3a, 3b, 4a, 4b. On the other hand, in FIG. 2, it can be seen that the second engaging portions 5a, 5b are overlapped, and the second engaging portions 6a, 6b are overlapped. The overlapped second engaging portions 5a, 5b are located above one open end of the bottom 9, and the overlapped second engaging portions 6a, 6b are located above the other open end of the bottom 9.

Also, as shown in Figure 3, when the support 100 is viewed from the bottom side, it can be seen that both open ends of the bottom 9 are supported by the first engaging parts 3a, 3b, 4a, and 4b. When a bag is placed in such a support 100, the basic weight of the bag is supported by the bottom surface consisting of the bottom 9 and the first engaging parts 3a, 3b, 4a, and 4b, and is supported by the front panel 1 and back panel 2 to prevent it from falling over. In this way, the support 100 according to this embodiment allows the bag to stand on its own.

<About the bag>
A bag supported by the support 100 according to the present embodiment will be described. FIG. 10 is a front view showing an example of a bag supported by the support 100 according to the present embodiment. The support 100 according to the present embodiment is suitable for supporting a bag called a standing pouch as shown in FIG. 10. The bag shown in FIG. 10 is formed using a front film 11, a back film 12, and a bottom film 13, which are laminated films. The laminated film has at least a base layer and a sealant layer. The bottom film 13 is folded back at a folding portion 13a and sandwiched between the front film 11 and the back film 12. Then, the opposing sealant layers are heat-sealed by applying heat to each other at a predetermined location to form a bag.

In FIG. 10, the shaded areas are the seals formed by heat sealing. The seals include an upper seal 14, side seals 15a and 15b, and a bottom seal 16. The bottom seal 16 is divided into a first bottom seal 16a and a second bottom seal 16b. The front film 11 and the back film 12 are joined in the upper seal 14, the side seals 15a and 15b, and the second bottom seal 16b. In the first bottom seal 16a, the bottom film 13 is joined to the front film 11 and the back film 12.

With the above-mentioned configuration, a bottom gusset portion 17 is formed at the bottom, allowing the bag to stand on its own. The inner edges of the above-mentioned seal portions define a storage portion 18. In the example of FIG. 10, the contents are omitted, but in reality, the storage portion 18 is filled with contents. The contents are filled from above, for example, before the upper seal portion 14 is formed. After filling, the upper seal portion 14 is formed and the bag is sealed. The bag has notches 19 in the side seal portions 15a and 15b for opening. The consumer can use the notches 19 to open the bag and remove the contents. In particular, it is beneficial to store the bag in a support 100 to prevent the bag from falling over after opening and opening the upper portion.

Figure 11 is a diagram showing a composite container according to one embodiment of the present disclosure. In Figure 11, the bag body 10 is inserted into the support body 100. In the example of Figure 11, an opened bag body is inserted through the notch 19, but an unopened bag body 10 may be inserted into the support body 100 to form a composite container.

Although the preferred embodiment of the present disclosure has been described above, the present disclosure is not limited to the above embodiment, and various modifications are possible. For example, in the above embodiment, in the direction along the first fold line f, the end point p2 of the second fold line g on the first and second bottom plate sides is located lower than the end point p1 on the first fold line side, but as long as the second fold line can be bent to stabilize the second portion of the engagement portion as part of the bottom surface, the end point p2 on the second bottom plate side does not necessarily need to be located lower than the end point p1 on the first fold line side.

Furthermore, in the present disclosure, the components shown in the above embodiments may be combined as appropriate, unless the combination is particularly difficult. Furthermore, in the present disclosure, a configuration may be made in which some of the components shown in the above embodiments are omitted.
