DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0016] Hereinafter, preferred embodiments of the present disclosure will be described in detail with reference to the drawings. <Support Structure> Fig. 1 is a perspective view of the support body according to an embodiment of the present disclosure, seen from the opening side. Fig. 2 is a top view of the support body according to an embodiment of the present disclosure. Fig. 3 is a bottom view of the support body according to an embodiment of the present disclosure. As shown in Figs. 1 to 3, the support body 100 according to an embodiment of the present disclosure forms a cylindrical sleeve with a front plate 1 and a rear plate 2 (shown as a rear plate first portion 2a and a rear plate second portion 2b in Figs. 1 and 2). A gripping portion 30 is provided on one side of the front panel 1 and the back panel 2 (to the side of the first fold line f2). Furthermore, a bottom portion 9 and locking portion first portions 3a, 3b, 4a, 4b are located so as to cover the lower side of the sleeve. The bottom portion 9 is composed of a first bottom plate 7 connected to the front panel 1 and a second bottom plate 8 connected to the back panel 2. This bottom portion 9 is fixed as a bottom surface by being locked between the locking portion first portions 3a, 3b, 4a, 4b and the locking portion second portions 5a, 5b, 6a, 6b. The locking portion second portions 5a, 5b, 6a, 6b are fixed upright from the locking portion first portions 3a, 3b, 4a, 4b to form a pair of protrusions 5t, 6t.

[0017] 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 on its own.

[0018] Fig. 4 is a diagram showing a support creation sheet 100a, which is a sheet for creating a support according to this embodiment. Fig. 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 cardboard, cardboard, or craft cardboard having a predetermined basis weight. The support creation sheet 100a may also be formed from a resin plate.

[0019] As shown in FIG. 4, the support member creating 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 member creating 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 by the adhesive portion S1 to form the back panel 2. Therefore, the front panel 1 and the back panel 2 form a cylindrical sleeve.

[0020] A first bottom plate 7 is connected to the lower side of the front plate 1 via a 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 a sixth fold line k. The first bottom plate first portion 7a of the first bottom plate 7 is connected to the front plate 1 via the fifth fold line j1.

[0021] A second bottom plate 8 is connected to the lower part of the second portion 2b of the rear panel via a fifth fold line j2. The second bottom plate 8 is later attached to the first bottom plate second portion 7b by an adhesive portion S2. The first bottom plate 7 and the second bottom plate 8 form a bottom portion 9. The bottom portion 9 connects the front panel 1 and the rear panel 2 below the support 100.

[0022] The first bottom plate 7 is located at the center of the front panel 1 in the longitudinal direction of the support member creating sheet 100a. The center of the front panel 1 in the longitudinal direction of the support member creating sheet 100a is the middle position between the first fold line f1 and the first fold line f2. The second bottom plate 8 is formed from the end of the back panel second portion 2b in the longitudinal direction of the support member creating sheet 100a. In this embodiment, the second bottom plate 8 is not connected to the back panel first portion 2a. As shown in Figs. 1 to 3, when the support member 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, 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 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.

[0023] As shown in FIG. 4, the first locking portion portion 3a is connected to the lower part of the front panel 1 via the second fold line g2. Similarly, the first locking portion portion 3b is connected to the lower part of the back panel first portion 2a via the second fold line g1. Furthermore, the second locking portion portion 5a is connected to the lower part of the first locking portion portion 3a via the fourth fold line i2. Similarly, the second locking portion portion 5b is connected to the lower part of the first locking portion portion 3b via the fourth fold line i1. The second locking portion portion 5a and the second locking portion portion 5b are connected to each other via 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 and i2.

[0024] 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. In addition, 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.

[0025] The first locking portion 4a is connected to the lower part 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 locking portion 4b is connected to the lower part of the back panel 2b via the second fold line g4. Furthermore, the second locking portion 6a is connected to the lower part of the first locking portion 4a via the fourth fold line i3. Similarly, the second locking portion 6b is connected to the lower part of the first locking portion 4b via the fourth fold line i4. The second locking portion 6a and the second locking portion 6b are connected to each other via the third fold line h2. The first fold line f2 and the third fold line h2 are on the same straight line, and are the boundary point of the end point P3. 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, respectively 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.

[0026] As in the vicinity of the first fold line f1, a recess is formed on the outer edge of the locking portion. Specifically, a recess o3 is formed between the outer edge of the locking portion first portion 4a and the outer edge of the locking portion second portion 6a, and a recess o4 is formed between the outer edge of the locking portion first portion 4b and the outer edge of the locking portion second portion 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 portion 4a and the locking portion first portion 4b have mutually symmetrical shapes and are positioned line-symmetrical to each other across the third fold line h2. In addition, the locking portion second portion 6a and the locking portion second portion 6b have mutually symmetrical shapes and are positioned line-symmetrical to each other across the third fold line h2.

[0027] 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. These locking portions are arranged to face each other across the bottom portion 9 in the completed support.

[0028] A total of 15 fold lines are formed on the support body creating sheet 100a, including the first fold lines f1 and f2, the second fold lines g1 to g4, the third fold lines h1 and h2, the fourth fold lines i1 to i4, the fifth fold lines j1 and 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 body 100 is formed, the third fold lines h1 and h2 are valley folds, and the second fold lines g1 to g4, the fourth fold lines i1 to i4, the fifth fold lines j1 and j2, and the sixth fold line k are all mountain folds.

[0029] The second fold lines g1-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 formed generally along the longitudinal direction of the support body creating 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 body creating sheet 100a in the longitudinal direction is a (mm), and the maximum length of the support body creating sheet 100a in the lateral direction is b (mm). As an example, when a=342 (mm) and b=259 (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 in the short direction of the support creation sheet 100a and the straight line connecting both ends P2, P2 is 3 mm. The distance between the center of the fifth fold line j2 in the short direction of the support creation sheet 100a and the straight line connecting both ends P2, P2 is also 3 mm. In this way, the fifth fold line j1 dividing the front panel 1 and the first bottom panel 7, and the fifth fold line j2 dividing 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.

[0030] 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-side 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 and both ends of the fifth fold line j1 in the short-side direction of the support body creating sheet 100a is 3 mm, the distance between both ends of the fifth fold line j1 and the end point P1 in the short-side direction of the support body creating sheet 100a is also 3 mm.

[0031] In this embodiment, the second fold lines g1 to g4 that divide the front panel 1, the rear panel 2, and the locking portion are curved slightly convex toward the front panel 1 and the rear panel 2. As an example, when the maximum length in the longitudinal direction a=342 (mm) and the short side direction b=259 (mm) shown in FIG. 4, the radius of curvature of the fifth fold lines j1 and j2 is 229.65 mm. As another example, when the maximum length in the longitudinal direction of the support member creating sheet 100a is a=342 (mm) and the short side direction b=259 (mm), the radius of curvature of the second fold lines g1 to g4 is 539.2 mm. In this way, since the second fold lines g1 to g4 that divide the front panel 1, the rear panel 2, and the locking portion are curved slightly convex toward the front panel 1 and the rear panel 2, it is easier to fold and form the locking portion than if they were straight.

[0032] In addition, the second fold line g1, the fourth fold line i1, 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 locking portions have shapes that are symmetrical with respect to the third fold line h1. Similarly, the second fold line g3, the fourth fold line i3, 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 locking portions have shapes that are symmetrical with respect to the third fold line h2.

[0033] 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 so as to be easily folded, or may be imaginary lines that are not actually processed. In reality, a thick cardboard is used as the support creating sheet 100a, so it is preferable that it is processed so as to be easily folded. 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 that are folded only in one direction are pressed lines. In addition, in the process of forming the support 100, the second fold lines g1-g4 and the third fold lines h1, h2 that are folded in both directions are perforated in conjunction with the pressed lines.

[0034] A bonding portion S1, shown by hatching, is formed near the end of the rear panel first portion 2a on the opposite side to the first fold line f1. The bonding portion S1 is formed so as to extend in the short direction of the support body forming sheet 100a. The bonding portion S1 formed on the outer surface side of the rear panel first portion 2a will later be bonded to the inner surface side of the rear panel second portion 2b to form the rear panel 2.

[0035] A bonding portion S2, shown by hatching, is formed near the end of the first bottom plate second portion 7b on the opposite side to the sixth fold line k. The bonding portion S2 is formed so as to extend in the longitudinal direction of the support body forming sheet 100a. The bonding portion S2 formed on the outer surface side of the first bottom plate second portion 7b will later be bonded to the inner surface side of the second bottom plate 8 to form the bottom portion 9.

[0036] <Creation of the 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, mountain folds are made at the first fold lines f1 and f2. 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 seen from the front panel 1 side. FIG. 6 shows the state seen from the back panel 2 side.

[0037] Next, the ends where the first fold lines f1 and f2 are located are pushed inward to deflect the front panel 1 and the back panel 2, and the fifth fold lines j1 and j2 are mountain folded. 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. Then, the first bottom panel second portion 7b and the second bottom panel 8 are adhered to each other to form the bottom portion 9. As a result, the front panel 1 and the 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 middle of being created.

[0038] 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 pressed inward, the third fold lines h1 and h2 are folded in a valley fold. Then, the second locking parts 5a and 5b enter the inside between the first locking parts 3a and 3b, and the second locking parts 6a and 6b enter the inside between the first locking parts 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 with each other, the state shown in FIG. 8 will be obtained. At this time, the second locking portions 5a, 5b are overlapped on the inside of the first locking portions 3a, 3b, and the second locking portions 6a, 6b are overlapped on the first locking portions 4a, 4b.

[0039] From the state shown in FIG. 8, the sixth fold line k is pushed upward together with the fourth fold lines i1 to i4. Then, the bottom 9, the locking portion first parts 3a, 3b, and the locking portion first parts 4a, 4b are adjusted to be in positions that form a bottom surface. The bottom 9 is pushed to a position where the first bottom plate first part 7a and the first bottom plate second part 7b form one surface. The locking portion first parts 3a, 3b are also pushed to a position where they form one surface. Furthermore, the locking portion first parts 4a, 4b are also pushed to a position where they form one surface. At this time, the bottom 9 is adjusted to be located in the recesses o1, o2 formed in the locking portion first parts 3a, 3b, and the recesses o3, o4 formed in the locking portion first parts 4a, 4b. By making such an adjustment, one end of the bottom 9 is sandwiched between the first locking portion 3a and the second locking portion 5a, and also 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 also between the first locking portion 4b and the second locking portion 6b.

[0040] Therefore, by sandwiching the bottom 9 between the two locking parts from both sides, the bottom 9 and the locking part first portions 3a, 3b, 4a, 4b can be made into a single bottom surface, completing the support body 100 according to this embodiment. Fig. 9 is a view of the support body 100 in the completed state seen from the front panel 1 side. Figs. 1 to 3 are a perspective view from the opening side, a top view, and a bottom view of the support body 100 in the completed state, respectively.

[0041] 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 locking parts 3a, 3b, 4a, and 4b. On the other hand, in FIG. 2, it can be seen that the second locking parts 5a and 5b are overlapped, and the second locking parts 6a and 6b are overlapped. The overlapped second locking parts 5a and 5b are located above one open end of the bottom 9, and the overlapped second locking parts 6a and 6b are located above the other open end of the bottom 9. The overlapped second locking parts 5a and 5b are located above the bottom 9 to form a protrusion 5t, and the overlapped second locking parts 6a and 6b are located above the bottom 9 to form a protrusion 6t.

[0042] 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 portions 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 portions 3a, 3b, 4a, and 4b, and is supported by the front plate 1 and the back plate 2 to prevent it from falling over. In this way, the support 100 according to this embodiment can make the bag stand on its own.

[0043] <About the bag> A pouch 10 supported by the support 100 according to the present embodiment will be described. FIG. 10 is a front view showing an example of the pouch 10 supported by the support 100 according to the present embodiment. The support 100 according to the present embodiment is suitable for supporting a pouch called a standing pouch as shown in FIG. 10. The pouch 10 shown in FIG. 10 is formed using a surface 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 the folded portion 13a and sandwiched between the surface 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 the pouch.

[0044] In Fig. 10, the hatched areas are the seals formed by heat sealing. The seals include an upper seal 14, side seals 15a and 15b, a bottom seal 16, and an inclined seal 17. The bottom seal 16 is divided into a first bottom seal 16a and a second bottom seal 16b. In the upper seal 14, the side seals 15a and 15b, the second bottom seal 16b, and the inclined seal 17, the front film 11 and the back film 12 are joined together. In the first bottom seal 16a, the bottom film 13 is joined to the front film 11 and the back film 12.

[0045] A spout 20 is joined to the inclined seal portion 17. The spout 20 is made of a resin molded product. The spout 20 has a tubular portion 29 and a fixing portion 28. The tubular portion 29 is formed in a cylindrical shape and connects the inside and outside of the bag body 10. A screw portion 27 is formed on the outer peripheral surface of the upper portion of the tubular portion 29, and the lid portion 21 is screwed onto the screw portion 27 to close the upper end of the spout 20.

[0046] The spouting tool 20 is attached to the bag body 10 by arranging and fixing the fixing portion 28 between the front film 11 and the back film 12 at the inclined seal portion 17.

[0047] With the above-mentioned configuration, a bottom gusset portion 19 is formed on the lower side, enabling the bag body 10 to stand on its own. In addition, the inner edges of the above-mentioned seal portions define the 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. Then, after filling, the upper seal portion 14 is formed and the bag body is sealed. The user can open the lid portion 21 and take out the contents from the tube portion 29 of the spouting tool 20. In particular, it is useful to store the bag body 10 in a support 100 so that the bag body 10 does not fall over after the spouting tool 20 is opened. Since the support 100 has protrusions 5t and 6t formed on the bottom 9, the contents can be stably taken out even if the bag body 10 is tilted.

[0048] Fig. 12 is an explanatory diagram for explaining a usage form of a composite container according to an embodiment of the present disclosure. As shown in Fig. 12, a user can insert his / her fingers into the opening of the gripping portion 30 provided on the support 100 to grip the container. This allows the user to stably take out the contents.

[0049] Fig. 11 is a diagram showing a composite container according to an embodiment of the present disclosure. Fig. 11 shows a state in which the bag body 10 is inserted into the support body 100. In the example of Fig. 11, a state in which the bag body 10 with the lid portion 21 already opened is shown, but an unopened bag body 10 may be inserted into the support body 100 to form a composite container.

[0050] 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, the end point P2 of the second fold line g on the first bottom plate 7 and the second bottom plate 8 side in the direction along the first fold lines f1 and f2 is located lower than the end point P1 on the first fold lines f1 and f2 side, but as long as the second fold lines g1, g2, g3, and g4 can be folded to stabilize the second parts 5a, 5b, 6a, and 6b of the engagement part 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.

[0051] In addition, in the present disclosure, the components shown in the above embodiments may be appropriately combined unless the combination is particularly difficult. In addition, in the present disclosure, a configuration may be made in which some of the components shown in the above embodiments are omitted. [Explanation of symbols]
