[0016] Hereinafter, an embodiment of the present invention will be described.

[0017] (First embodiment) First, a container 100a of a first embodiment will be described with reference to FIGS.

[0018] 1 and 2, the container 100a includes a body 1a including a front body 11a and a rear body 12a, a bottom 2a disposed at the lower end of the body 1a, and a glue tab 3 for closing the side ends of the front body 11a and the rear body 12a. As shown in FIG. 1, the container 100a is configured such that the bottom 2a can be folded between the front body 11a and the rear body 12a.

[0019] As shown in Fig. 2, the container 100a is configured to be self-supporting and to form a storage space by unfolding the bottom 2a. Contents (not shown) can be put in and taken out of the container 100a through an opening at the upper end of the body 1a. A hole 13 is formed at the upper end of the body 1a, allowing the container 100a to be suspended.

[0020] The front body portion 11a, the rear body portion 12a, the bottom portion 2a, and the adhesive portion 3 are formed of a single sheet material 100A (see FIG. 4). This sheet material 100A is made of paper, for example, and is not coated with a resin film or the like. In other words, the sheet material 100A is a single layer of paper, and the container 100a does not have barrier properties.

[0021] Here, the sheet material 100A as shown in Fig. 4 is formed, for example, by punching. The sheet material 100A has holes 13 formed during punching. Furthermore, folds Fa1 to Fa7 are formed in the sheet material 100A. Note that the fold Fa1 is an example of a "first fold" of the present invention, the fold Fa2 is an example of a "second fold" of the present invention, the fold Fa3 is an example of a "third fold" of the present invention, the fold Fa4 is an example of a "fourth fold" of the present invention, the fold Fa5 is an example of a "fifth fold" of the present invention, and the fold Fa6 is an example of a "sixth fold" of the present invention.

[0022] This sheet material 100A is substantially rectangular and includes a front body portion 11a, a rear body portion 12a, a bottom portion 2a, and a glue tab portion 3. The bottom portion 2a is connected to the front body portion 11a via a fold line Fa1, and the rear body portion 12a is connected to the bottom portion 2a via a fold line Fa2. That is, the front body portion 11a, the bottom portion 2a, and the rear body portion 12a are arranged so as to be continuous in the longitudinal direction (X direction), and the bottom portion 2a is arranged between the front body portion 11a and the rear body portion 12a. A hole portion 13 is formed in each of the front body portion 11a and the rear body portion 12a. The front body portion 11a, the rear body portion 12a, and the bottom portion 2a are set so as to have the same dimensions in the short direction (Y direction). The fold lines Fa1 and Fa2 are formed so as to extend in the Y direction.

[0023] The front body portion 11a is connected to the adhesive portion 3 via a fold line Fa6. The adhesive portion 3 is formed so as to protrude outward in the short side direction from the front body portion 11a, and is provided over the entire length of the front body portion 11a in the longitudinal direction. The fold line Fa6 is formed so as to extend in the X direction.

[0024] The bottom 2a includes a bottom main body 21a that becomes the lower end of the storage space when unfolded, a front attachment part 22a that is attached to the lower end 111a of the front body part 11a, and a rear attachment part 23a that is attached to the lower end 121a of the rear body part 12a. The bottom main body 21a and the front attachment part 22a are connected via a fold Fa4, and the bottom main body 21a and the rear attachment part 23a are connected via a fold Fa5. The fold Fa4 is curved so that its center is located on the front body part 11a side with respect to both ends in the Y direction. The fold Fa5 is curved so that its center is located on the rear body part 12a side with respect to both ends in the Y direction.

[0025] The front attachment portion 22a is disposed on the front body 11a side with respect to the bottom body 21a, and is connected to the lower end 111a via the fold line Fa1. That is, the front attachment portion 22a is partitioned by the fold lines Fa1 and Fa4. The rear attachment portion 23a is disposed on the rear body 12a side with respect to the bottom body 21a, and is connected to the lower end 121a via the fold line Fa2. That is, the rear attachment portion 23a is partitioned by the fold lines Fa2 and Fa5.

[0026] The bottom body 21a is defined by folds Fa4 and Fa5 and is formed into an elliptical shape. The bottom body 21a has a fold Fa3 extending in the Y direction and has a main body front side 211a and a main body rear side 212a. The main body front side 211a is defined by folds Fa3 and Fa4 and is formed into a semi-elliptical shape. The main body rear side 212a is defined by folds Fa3 and Fa5 and is formed into a semi-elliptical shape. In addition, the bottom body 21a has two folds Fa7 extending in the X direction, and the two folds Fa7 are spaced apart in the Y direction.

[0027] The front body portion 11a, the front attachment portion 22a, and the main body front side 211a, and the rear body portion 12a, the rear attachment portion 23a, and the main body rear side 212a are formed symmetrically with respect to the fold line Fa3.

[0028] Then, in such a sheet material 100A, the folds Fa1 and Fa2 are valley-folded, and the fold Fa3 is mountain-folded. As a result, the front body section 11a and the rear body section 12a are stacked, and the bottom section 2a folded in half is sandwiched between the stacked front body section 11a and rear body section 12a. At this time, the front attachment section 22a is attached to the lower end section 111a of the front body section 11a, and the rear attachment section 23a is attached to the lower end section 121a of the rear body section 12a. The bottom section 2a is folded back at the fold Fa3, and the front attachment section 22a and the main body front side 211a are arranged on the same plane, and the rear attachment section 23a and the main body rear side 212a are arranged on the same plane. Next, the fold Fa6 is valley-folded, and the glue margin section 3 is attached to the side end section of the rear body section 12a. In this manner, a container 100a as shown in FIG. 1 is manufactured.

[0029] In this container 100a, the gap between the flat cylindrical front body portion 11a and rear body portion 12a is expanded, and the folds Fa4 and Fa5 are folded and the fold Fa3 is stretched, as shown in Fig. 2, so that the bottom portion 2a is unfolded. At this time, the bottom body 21a becomes the bottom surface of the storage space. The bottom portion 2a is formed to have an elliptical shape when viewed from the bottom surface side in the unfolded state, as shown in Fig. 3.

[0030] In the container 100a, the legs are formed by the lower end 111a of the front body 11a and the front attachment part 22a, and the legs are formed by the lower end 121a of the rear body 12a and the rear attachment part 23a. Therefore, when the container 100a is placed on a placement surface (not shown), the folds Fa1 and Fa2 come into contact with the placement surface. At this time, the bottom body 21a is spaced from the placement surface.

[0031] -effect- In the first embodiment, as described above, the container 100a is made of one sheet material 100A, so that the number of parts can be reduced.

[0032] Furthermore, in the first embodiment, the container 100a is made of paper, which reduces the environmental impact compared to a plastic container.

[0033] Furthermore, in the first embodiment, the fold Fa7 is formed in the bottom body 21a, which makes it easier for the bottom 2a to unfold.

[0034] Second embodiment Next, a container 100b according to a second embodiment will be described with reference to FIGS.

[0035] 5 and 6, the container 100b includes a body 1b including a front body 11b and a rear body 12b, a bottom 2b disposed at the lower end of the body 1b, and a glue tab 3 for closing the side ends of the front body 11b and the rear body 12b. As shown in FIG. 5, the container 100b is configured such that the bottom 2b can be folded between the front body 11b and the rear body 12b.

[0036] As shown in Fig. 6, the container 100b is configured to be self-supporting and to form a storage space by unfolding the bottom 2b. Contents (not shown) can be put in and taken out of the container 100b through an opening at the upper end of the body 1b. A hole 13 is formed at the upper end of the body 1b, allowing the container 100b to be suspended.

[0037] The front body portion 11b, the rear body portion 12b, the bottom portion 2b, and the adhesive portion 3 are formed of a single sheet material 100B (see FIG. 8). This sheet material 100B is made of paper, for example, and is not coated with a resin film or the like. In other words, the sheet material 100B is a single layer of paper, and the container 100b does not have barrier properties.

[0038] Here, the sheet material 100B as shown in Fig. 8 is formed, for example, by punching. The sheet material 100B has holes 13 formed during punching. Furthermore, folds Fb1 to Fb8 are formed in the sheet material 100B. Note that the fold Fb1 is an example of a "first fold" of the present invention, the fold Fb2 is an example of a "second fold" of the present invention, the fold Fb3 is an example of a "third fold" of the present invention, the fold Fb4 is an example of a "fourth fold" of the present invention, the fold Fb5 is an example of a "fifth fold" of the present invention, and the fold Fb6 is an example of a "sixth fold" of the present invention.

[0039] This sheet material 100B is substantially rectangular, and includes a front body portion 11b, a rear body portion 12b, a bottom portion 2b, and a glue tab portion 3. The bottom portion 2b is connected to the front body portion 11b via a fold Fb1, and the rear body portion 12b is connected to the bottom portion 2b via a fold Fb2. That is, the front body portion 11b, the bottom portion 2b, and the rear body portion 12b are arranged so as to be continuous in the longitudinal direction (X direction), and the bottom portion 2b is arranged between the front body portion 11b and the rear body portion 12b. The front body portion 11b and the rear body portion 12b each have a hole portion 13. The front body portion 11b, the rear body portion 12b, and the bottom portion 2b are set so as to have the same dimensions in the short direction (Y direction). The folds Fb1 and Fb2 are formed so as to extend in the Y direction.

[0040] The front body portion 11b is connected to the adhesive portion 3 via a fold Fb6. The adhesive portion 3 is formed to protrude outward from the front body portion 11b in the short side direction and is provided over the entire length of the front body portion 11b in the longitudinal direction. The fold Fb6 is formed to extend in the X direction.

[0041] The bottom 2b includes a bottom body 21b that becomes the lower end of the storage space when unfolded, a front attachment part 22b that is attached to the lower end 111b of the front body part 11b, and a rear attachment part 23b that is attached to the lower end 121b of the rear body part 12b. The bottom body 21b and the front attachment part 22b are connected via a fold Fb4, and the bottom body 21b and the rear attachment part 23b are connected via a fold Fb5. The fold Fb4 has a straight part that extends in the Y direction near the fold Fb1, and inclined parts that are inclined from both ends of the straight part so as to move away from the fold Fb1. The fold Fb5 has a straight part that extends in the Y direction near the fold Fb2, and inclined parts that are inclined from both ends of the straight part so as to move away from the fold Fb2.

[0042] The front attachment portion 22b is disposed on the front body 11b side with respect to the bottom body 21b, and is connected to the lower end 111b via the fold Fb1. That is, the front attachment portion 22b is defined by the folds Fb1 and Fb4. The rear attachment portion 23b is disposed on the rear body 12b side with respect to the bottom body 21b, and is connected to the lower end 121b via the fold Fb2. That is, the rear attachment portion 23b is defined by the folds Fb2 and Fb5.

[0043] The bottom body 21b is defined by folds Fb4 and Fb5 and is formed into a hexagonal shape. The bottom body 21b has a fold Fb3 extending in the Y direction and has a main body front side 211b and a main body rear side 212b. The main body front side 211b is defined by folds Fb3 and Fb4 and is formed into a trapezoid shape. The main body rear side 212b is defined by folds Fb3 and Fb5 and is formed into a trapezoid shape.

[0044] In addition, two folds Fb7 extending in the X direction are formed in the bottom portion 2b, and the two folds Fb7 are spaced apart in the Y direction. The folds Fb7 are arranged so as to pass through two vertices (corners) of the hexagonal bottom body 21b. Therefore, the two folds Fb7 divide the bottom body 21b into a rectangular region 213b and triangular regions 214b arranged at both ends of the region 213b in the Y direction. In addition, a fold Fb8 is formed in each of the front body portion 11b and the rear body portion 12b so as to be continuous with the folds Fb7.

[0045] The front body portion 11b, the front attachment portion 22b, and the main body front side 211b, and the rear body portion 12b, the rear attachment portion 23b, and the main body rear side 212b are formed symmetrically with respect to the fold line Fb3.

[0046] Then, in such a sheet material 100B, the folds Fb1 and Fb2 are valley-folded, and the fold Fb3 is mountain-folded. As a result, the front body section 11b and the rear body section 12b are stacked, and the bottom section 2b folded in half is sandwiched between the stacked front body section 11b and rear body section 12b. At this time, the front attachment section 22b is attached to the lower end section 111b of the front body section 11b, and the rear attachment section 23b is attached to the lower end section 121b of the rear body section 12b. The bottom section 2b is folded back at the fold Fb3, and the front attachment section 22b and the main body front side 211b are arranged on the same plane, and the rear attachment section 23b and the main body rear side 212b are arranged on the same plane. Next, the fold Fb6 is valley-folded, and the glue tab section 3 is attached to the side end section of the rear body section 12b. In this manner, a container 100b as shown in FIG. 5 is manufactured.

[0047] In this container 100b, the gap between the flat cylindrical front body portion 11b and rear body portion 12b is expanded, and as shown in Fig. 6, the folds Fb4 and Fb5 are folded and the fold Fb3 is stretched, so that the bottom portion 2b is unfolded. At this time, the bottom body 21b becomes the bottom surface of the storage space. As shown in Fig. 7, the bottom portion 2b is formed to have a hexagonal shape when viewed from the bottom side in the unfolded state.

[0048] In the container 100b, the legs are formed by the lower end 111b of the front body 11b and the front attachment part 22b, and the legs are formed by the lower end 121b of the rear body 12b and the rear attachment part 23b. Therefore, when the container 100b is placed on a placement surface (not shown), the folds Fb1 and Fb2 are abutted against the placement surface. At this time, the bottom body 21b is spaced apart from the placement surface. In the bottom body 21b, the rectangular area 213b is arranged parallel to the placement surface, and the triangular area 214b is inclined upward from the area 213b.

[0049] -effect- In the second embodiment, as described above, by forming the fold Fb8 in the front torso section 11b and the rear torso section 12b, it is possible to make it easier for the bottom portion 2b to be maintained in a hexagonal state when the bottom portion 2b is unfolded.

[0050] Other effects of the second embodiment are similar to those of the first embodiment.

[0051] Third embodiment Next, a container 100c according to a third embodiment will be described with reference to FIGS.

[0052] 9 and 10, the container 100c includes a body 1c including a front body 11c and a rear body 12c, a bottom 2c disposed at the lower end of the body 1c, and a glue tab 3 for closing the side ends of the front body 11c and the rear body 12c. As shown in FIG. 9, the container 100c is configured such that the bottom 2c can be folded between the front body 11c and the rear body 12c.

[0053] As shown in Fig. 10, the container 100c is configured to be self-supporting and to form a storage space by unfolding the bottom 2c. Contents (not shown) can be put in and taken out of the container 100c through an opening at the upper end of the body 1c. A hole 13 is formed at the upper end of the body 1c, allowing the container 100c to be suspended.

[0054] The front body portion 11c, the rear body portion 12c, the bottom portion 2c, and the adhesive portion 3 are formed of a single sheet material 100C (see FIG. 13). This sheet material 100C is made of paper, for example, and is not coated with a resin film or the like. In other words, the sheet material 100C is a single layer of paper, and the container 100c does not have barrier properties.

[0055] Here, the sheet material 100C as shown in Fig. 13 is formed, for example, by punching. The sheet material 100C has holes 13 formed during punching. Furthermore, folds Fc1 to Fc12 are formed in the sheet material 100C. Note that the fold Fc1 is an example of a "first fold" of the present invention, the fold Fc2 is an example of a "second fold" of the present invention, the fold Fc3 is an example of a "third fold" of the present invention, the fold Fc4 is an example of a "fourth fold" of the present invention, the fold Fc5 is an example of a "fifth fold" of the present invention, and the fold Fc6 is an example of a "sixth fold" of the present invention.

[0056] This sheet material 100C is substantially rectangular and includes a front body portion 11c, a rear body portion 12c, a bottom portion 2c, and a glue tab portion 3. The bottom portion 2c is connected to the front body portion 11c via a fold Fc1, and the rear body portion 12c is connected to the bottom portion 2c via a fold Fc2. That is, the front body portion 11c, the bottom portion 2c, and the rear body portion 12c are arranged so as to be continuous in the longitudinal direction (X direction), and the bottom portion 2c is arranged between the front body portion 11c and the rear body portion 12c. The front body portion 11c and the rear body portion 12c each have a hole portion 13. The front body portion 11c, the rear body portion 12c, and the bottom portion 2c are set so as to have the same dimensions in the short direction (Y direction). The folds Fc1 and Fc2 are formed so as to extend in the Y direction.

[0057] The front body portion 11c is connected to the adhesive portion 3 via a fold Fc6. The adhesive portion 3 is formed to protrude outward from the front body portion 11c in the short side direction and is provided over the entire length of the front body portion 11c in the longitudinal direction. The fold Fc6 is formed to extend in the X direction.

[0058] The bottom 2c includes a bottom body 21c that becomes the lower end of the storage space when unfolded, a front attachment part 22c that is attached to the lower end 111c of the front body part 11c, and a rear attachment part 23c that is attached to the lower end 121c of the rear body part 12c. The bottom body 21c and the front attachment part 22c are connected via a fold Fc4, and the bottom body 21c and the rear attachment part 23c are connected via a fold Fc5. The fold Fc4 has a straight part that extends in the Y direction near the fold Fc1, and inclined parts that are inclined from both ends of the straight part so as to move away from the fold Fc1. The fold Fc5 has a straight part that extends in the Y direction near the fold Fc2, and inclined parts that are inclined from both ends of the straight part so as to move away from the fold Fc2.

[0059] The front attachment portion 22c is disposed on the front body 11c side with respect to the bottom body 21c, and is connected to the lower end 111c via the fold Fc1. That is, the front attachment portion 22c is partitioned by the folds Fc1 and Fc4. The rear attachment portion 23c is disposed on the rear body 12c side with respect to the bottom body 21c, and is connected to the lower end 121c via the fold Fc2. That is, the rear attachment portion 23c is partitioned by the folds Fc2 and Fc5.

[0060] The bottom body 21c is defined by folds Fc4 and Fc5 and is formed into a hexagonal shape. The bottom body 21c has a fold Fc3 extending in the Y direction and has a main body front side 211c and a main body rear side 212c. The main body front side 211c is defined by folds Fc3 and Fc4 and is formed into a trapezoid shape. The main body rear side 212c is defined by folds Fc3 and Fc5 and is formed into a trapezoid shape.

[0061] In addition, two folds Fc7 extending in the X direction are formed in the bottom 2c, and the two folds Fc7 are spaced apart in the Y direction. The folds Fc7 are arranged so as to pass through two vertices (corners) of the hexagonal bottom body 21c. Therefore, the two folds Fc7 divide the bottom body 21c into a rectangular region 213c and triangular regions 214c located at both ends of the region 213c in the Y direction.

[0062] Furthermore, folds Fc8 to Fc10 are formed in the front torso portion 11c and the rear torso portion 12c, respectively. The folds Fc8 and Fc9 separate the side surface forming portions 112c and 122c that form the side surfaces of the storage space when the bottom portion 2c is unfolded. The fold Fc8 is formed to extend in the X direction and is provided so as to be continuous with the fold Fc7. The fold Fc9 is provided so as to be continuous with the fold Fc8 and is formed to be inclined outward in the Y direction from the fold Fc8. The fold Fc10 is formed to extend outward in the Y direction from the boundary between the folds Fc8 and Fc9.

[0063] Folds Fc11 and Fc12 are formed in the margin portion 3. The fold Fc11 is formed so as to be line-symmetrical with the fold Fc9 with respect to the fold Fc6. The fold Fc12 is formed so as to be line-symmetrical with the fold Fc10 with respect to the fold Fc6.

[0064] The front body portion 11c, the front attachment portion 22c, and the main body front side 211c, and the rear body portion 12c, the rear attachment portion 23c, and the main body rear side 212c are formed symmetrically with respect to the fold line Fc3.

[0065] Then, in such a sheet material 100C, the folds Fc1 and Fc2 are valley-folded, and the fold Fc3 is mountain-folded. As a result, the front body portion 11c and the rear body portion 12c are stacked, and the bottom portion 2c folded in half is sandwiched between the stacked front body portion 11c and the rear body portion 12c. At this time, the front attachment portion 22c is attached to the lower end portion 111c of the front body portion 11c, and the rear attachment portion 23c is attached to the lower end portion 121c of the rear body portion 12c. Note that the bottom portion 2c is folded back at the fold Fc3, and the front attachment portion 22c and the main body front side 211c are arranged on the same plane, and the rear attachment portion 23c and the main body rear side 212c are arranged on the same plane. Next, the fold Fc6 is valley-folded, and the glue margin portion 3 is attached to the side end portion of the rear body portion 12c. In this manner, a container 100c as shown in FIG. 9 is manufactured.

[0066] In this container 100c, the distance between the flat cylindrical front body portion 11c and rear body portion 12c is expanded, and folds Fc8 to Fc10 are folded. As a result, as shown in Fig. 10, folds Fc4 and Fc5 are folded and fold Fc3 is stretched, thereby unfolding the bottom portion 2c. As shown in Fig. 11, the bottom portion 2c is formed to have a rectangular shape when viewed from the bottom side in the unfolded state.

[0067] In addition, in the container 100c, the legs are formed by the lower end 111c of the front body 11c and the front attachment part 22c, and the legs are formed by the lower end 121c of the rear body 12c and the rear attachment part 23c. Therefore, when the container 100c is placed on a placement surface (not shown), the folds Fc1 and Fc2 are abutted against the placement surface. At this time, the bottom body 21c is spaced apart from the placement surface. In the bottom body 21c, the rectangular area 213c is arranged parallel to the placement surface, and the triangular area 214c is raised at a substantially right angle from the area 213c. That is, the rectangular area 213c is the bottom surface of the storage space, and the triangular area 214c constitutes the side surface of the storage space.

[0068] Below the body 1c of the container 100c, the side surfaces of the storage space are formed by the side surface forming parts 112c and 122c. The dimensions of the side surfaces are constant from the lower end to the fold Fc10, and become smaller as they move upward from the fold Fc10, disappearing before reaching the upper end. For this reason, in the container 100c, as shown in FIG. 12, when the bottom 2c is unfolded, the opening at the upper end of the body 1c is easily kept closed.

[0069] -effect- In the third embodiment, as described above, folds Fc8 to Fc10 are formed in front torso section 11c and rear torso section 12c, thereby making it possible to form side surfaces on the underside of torso section 1c.

[0070] Other effects of the third embodiment are similar to those of the first embodiment.
