(Operation of sheet body 100 for container formation)
Next, the operation of the container forming sheet body 100 configured as described above will be described. First, the user of the container forming sheet body 100 is a container in which one bottom plate 110, a pair of first side walls 120, 140 and a pair of second side walls 160, 170 are formed on one sheet-shaped corrugated cardboard material, respectively. A forming sheet body 100 is prepared (see FIGS. 1 and 2). In this case, the container forming sheet body 100 can be formed by using a known cutting device that cuts the sheet-shaped corrugated cardboard material into an arbitrary shape.

Next, the user assembles the container forming sheet body 100 into the container 180. Specifically, as shown in FIG. 3, the user folds the ruled line 122 and the ruled line 125 so that the inner side wall 126 for the first side wall of the first side wall 120 overlaps the outer wall 121 for the first side wall. As a result, the user can arrange the inner side wall 126 for the first side wall facing each other on the outer wall 121 for the first side wall in a state where the ceiling portion 124 for the first side wall is formed. In this case, since the inner side wall 126 for the first side wall and the second inner piece 137 in the second side wall constituent piece 130 are separated from each other, the user can easily fold the inner side wall 126 for the first side wall. .. Next, the user folds the inner side wall 146 for the first side wall in the first side wall 140 on the outer wall 141 for the first side wall in the same manner as the inner side wall 126 for the first side wall.

Next, as shown in FIG. 4, the user folds the ruled line 111a so that the outer wall 121 for the first side wall of the first side wall 120 stands upright with respect to the bottom plate 110. In this case, the user inserts the two first side wall engaging protrusions 128 formed at the tip of the first side wall inner side wall 126 into the two first side wall engaging through holes 113 formed in the bottom plate 110. Insert each. As a result, the user can erect the first side wall 120 with respect to the bottom plate 110 in a state where the rebound due to the springback (restoring force) of the inner side wall 126 for the first side wall is restricted.

In this case, since the second side wall constituent piece 130 is formed by being connected to the first side wall outer wall 121, it stands up like the first side wall outer wall 121. Further, in this case, since the side side 161a of the second side wall 160 is formed by being recessed in a concave shape, the user can suppress the rubbing against the second side wall 160 and erect the second side wall component 130. Next, the user folds the outer wall 141 for the first side wall of the first side wall 140 so as to stand up against the bottom plate 110 in the same manner as the outer wall 121 for the first side wall.

Next, as shown in FIG. 5, the user folds the two second side wall constituent pieces 130 along the two ruled lines 123 and rotates the second inner side piece 137 toward the inner side wall 126 for the first side wall. Fold it along the ruled lines 133a and 133b and the ruled lines 136a and 136b, respectively, and arrange them so as to face the first inner piece 131. In this case, the user inserts the second side wall engaging protrusion 138 formed at the tip of the second inner piece 137 into the second side wall engaging through hole 114 formed in the bottom plate 110. As a result, the user can erect the second side wall constituent piece 130 with respect to the bottom plate 110 in a state where the bounce of the first inner piece 131 and the second inner piece 137 due to the springback is restricted. In this case, the second side wall constituent piece 130 extends in a direction orthogonal to the first side wall 120 and stands up in a state where the connecting portion 134 and the locking portion 135 are formed respectively.

In the assembling work of the second side wall component 130, the user suppresses rubbing against the second side wall 160 because the lower side 131a of the first inner piece 131 is inclined upward, and the second side wall component 130. Can be rotated. Further, since the user is formed so that the opposite side 137a of the second inner piece 137 is inclined so as to be separated from the inner side wall 126 for the first side wall, the inside of the second inner piece 137 for the first side wall is formed. It is possible to suppress the pressure on the wall 126 and position it on the bottom plate 110, and it is possible to facilitate the insertion of the second side wall engaging protrusion 138 into the second side wall engaging through hole 114. Further, since the notch 114a is formed in the engagement through hole 114 for the second side wall, the user can deform the circumference of the engagement through hole 114 for the second side wall to form the engagement protrusion 138 for the second side wall. It can be easily inserted.

Next, as shown in FIG. 6, the user folds the two second side wall component pieces 150 along the two ruled lines 142 to the side of the inner side wall for the first side wall, respectively, as in the case of the second side wall component piece 130. While rotating, the second inner piece 157 is folded along the ruled lines 153a and 153b and the ruled lines 156a and 156b, respectively, and arranged so as to face the first inner piece 151. In this case, the user sandwiches the free end side (second side wall component 150 side) of the second side wall component 130 between the first inner piece 151 and the second inner piece 157 so as to cover the second side wall component piece. The 150 is placed on the bottom plate 110. As a result, in the second side wall constituent piece 150, the lock portion 135 of the second side wall constituent piece 130 is fitted in the fitting opening 159, and the lock portion 155 is the fitting opening 139 of the second side wall constituent piece 130. Fits inside.

Then, the user inserts the second side wall engaging protrusion 158 formed at the tip of the second inner piece 157 into the second side wall engaging through hole 114 formed in the bottom plate 110. As a result, the user can rebound the first inner piece 151 and the second inner piece 157 with each springback in a state where a part of the second side wall component 150 is fitted to a part of the second side wall component 130. The second side wall constituent piece 150 can be erected with respect to the bottom plate 110 in a regulated state. In this case, since the facing side 157a of the second inner piece 157 is formed so as to be inclined so as to be separated from the inner side wall 146 for the first side wall, the user is formed for the first side wall of the second inner piece 157. The second side wall engaging protrusion 138 can be easily inserted into the second side wall engaging through hole 114 by suppressing the pressure on the inner side wall 146 and easily positioning it on the bottom plate 110.

In the present embodiment, the second side wall structure piece 130 is assembled and then the second side wall structure piece 150 is assembled, but the second side wall structure piece 130 can be assembled and then the second side wall structure piece 130 is assembled. Further, one of the second side wall constituent piece 130 and the second side wall constituent piece 150 can be arranged inside and assembled at the same time.

Next, as shown in FIG. 7, the user bends the second side wall 160 along the ruled line 112a, the ruled line 163, and the ruled line 165, respectively, to cover the second side wall component 130 and the second side wall component 150, respectively. In this case, the user can hook the two hooking portions 167 into the notches 127 of the first side walls 120 and 140 by slightly bending the two ruled lines 168. As a result, the user sandwiches the second side wall component 130 and the second side wall component 150 between the second side wall outer wall 161 and the second side wall inner side wall 166 while forming the second side wall ceiling portion 164. In this state, the second side wall 160 can be erected on the bottom plate 110. In this case, the handle portion 162 of the second side wall 160 is arranged so as to face the inner handle portions 132 and 152 of the second side wall constituent pieces 130 and 150.

Next, the user folds the second side wall 170 so as to stand up against the bottom plate 110 in the same manner as the second side wall 160. As a result, the user can assemble the container forming sheet 100 as a box-shaped container 180 having an open upper part.

Next, the user can use the container 180 as a container. Specifically, the user can transport or store the container 180 by placing the contained object on the bottom plate 110. In this case, the user can insert a finger into the handle portion 162 to grip the container 180. In this case, since the handle portion 162 is formed by communicating the inner handle portion 132, the user can insert a finger into the inner handle portion 132 to grip the container 180, and the contact area with respect to the finger can be obtained. It is possible to prevent the pressure on the finger and the damage of the handle portion 162 by increasing the pressure.

Next, the user can disassemble the container 180. Specifically, the user can expand the container 180 and return it to the container forming sheet 100 by a procedure opposite to the procedure for assembling the container forming sheet 100 into the container 180. In this case, the user inserts a finger into the notches 166a, 176a formed in the inner side walls 166, 176 for the second side wall of the second side wall 160, 170, and inserts the inner side wall for the second side wall 166, 176. It can be removed from the inner side walls 126 and 146 for the first side wall of the side walls 120 and 140.

As can be understood from the above operation description, according to the above embodiment, the container forming sheet body 100 is separated because the second inner pieces 137 and 157 are not connected to the first side wall inner side walls 126 and 146. Since the second side wall constituent pieces 130 and 150 can be bent with a small force when the second side wall constituent pieces 130 and 150 are bent with respect to the first side wall 120 and 140, the work load at the time of assembling the container 180 can be reduced. .. Further, the container forming sheet body 100 can easily bend the inner side walls 126, 146 for the first side wall with respect to the outer walls 121, 141 for the first side wall.

Further, the implementation of the present invention is not limited to the above embodiment, and various changes can be made as long as the object of the present invention is not deviated. In the description of each modification, the same reference numerals are given to the same parts as those in the above embodiment.

For example, in the above embodiment, the container forming sheet body 100 is configured by separating the second inner piece 137 in the first side wall 120 with respect to the inner side wall 126 for the first side wall, and the second side wall 140. The inner piece 157 was separated from the inner side wall 146 for the first side wall. However, the container forming sheet body 100 is configured by separating the second inner pieces 137 and 157 with respect to the first side wall inner side walls 126 and 146 for at least one of the first side wall 120 and the first side wall 140. Just do it.

Further, in the above embodiment, the second inner piece 137, 157 and the first side wall inner side wall 126, 146 are formed in a state of being separated from each other. However, it is also possible to form a notch between the second inner piece 137, 157 and the first side wall inner side wall 126, 146 so that they are in contact with each other. According to this, in the container forming sheet body 100, the manufacturing load can be reduced as compared with the case where the second inner piece 137, 157 and the first side wall inner side wall 126, 146 are formed so as to be separated from each other. ..

Further, in the above embodiment, the facing sides 137a and 157a in the second inner pieces 137 and 157 are inside for the first side wall from the first inner piece 131 and 151 side toward the outer side 137b and 157b side which are free ends. It was formed at an angle so as to be separated from the walls 126 and 146. However, the opposite sides 137a and 157a in the second inner pieces 137 and 157 are relative to the inner side walls 126 and 146 for the first side wall toward the outer sides 137b and 157b, which are free ends, from the first inner pieces 131 and 151 sides. It can also be formed in parallel.

Further, in the above embodiment, the lock portions 135 and 155 are flat and flush with each other so as to extend horizontally between the first inner piece 131 and the second inner piece 137 when the container 180 is assembled. Formed. As a result, the container 180 can prevent damage when the second side wall ceiling portions 164, 174 of the second side wall 160, 170 are strongly pressed against the lock portions 135, 155 due to the load in the case of stacking. However, the lock portions 135 and 155 can also be formed in a chevron shape pointed upward.

For example, as shown in FIGS. 8 (A), 8 (B) and 9, the lock portion 135 is located on the lock portion 135, 155 side of the opening width on the connecting portion 134, 154 side in the fitting openings 139, 159, respectively. The ruled lines 133b, 153b or the ruled lines 136b, 156b are formed by forming one of the ruled lines 133b, 153b and the ruled lines 136b, 156b within the opening width on the lock portion 135, 155 side. It can be formed in a chevron shape as the top (ridge line). In this case, the other of the ruled lines 133b, 153b and the ruled lines 136b, 156b may be formed within the opening width on the lock portion 135, 155 side of the fitting openings 139, 159, or may be formed outside the opening width.

A groove-shaped separation portion 190 cut out in a state of reaching the outer peripheral portions of the second side wall constituent pieces 130 and 150 was provided in the second side wall structure piece 130 and 150, and the two were partially separated from each other. Thereby, the second side wall constituent pieces 130, 150 can easily fold the ruled lines 133b, 153b and the ruled lines 136b, 156b at the time of assembling the second side wall constituent pieces 130, 150. The separation portion 190 may be formed of a linear cutting line instead of the notch.

Further, as shown in FIGS. 10 and 11, for example, the lock portion 135 forms an opening width on the lock portion 135 side wider than the opening width on the connecting portion 134 side in the fitting opening 139, and the lock portion 135 is formed. A pair of ruled lines 133b and a ruled line 136b are formed concentrically with respect to the opening width on the portion 135 side, and a ruled line 191 is formed between the pair of ruled lines 133b and the ruled line 136b to form the ruled line 191 at the top (ridge line). ) Can be formed into a chevron shape.

Further, in the above embodiment, the inner side walls 126 and 146 for the first side wall did not form the portions constituting the second side walls 160 and 170. However, at least one of the inner side wall 126 for the first side wall and the inner side wall 146 for the first side wall may be formed with a portion constituting the second side wall 160, 170. Specifically, as shown in FIG. 12, a third inner piece 192 can be formed on the inner side wall 126 for the first side wall from the side side of the inner side wall 126 for the first side wall via the ruled line 191. The third inner piece 192 is arranged adjacent to the second inner piece 137 by folding the ruled line 191 at the time of assembling the container 180. Therefore, the second inner piece 137 is formed smaller by the size of the third inner piece 192, and is formed in a state of being separated from the third inner piece 192.

In the container 180 provided with such a third inner piece 192, the second side wall 160, 170 is assembled to the bottom plate 110, so that the second side wall inner side wall 166, 176 presses the third inner piece 192. As a result, in the container 180, the inner side wall 126 for the first side wall is fixed to the second side wall 160, 170, so that the rigidity of the first side wall 120, 140 can be improved.

Further, in the above embodiment, the width of the engagement through hole 113 for the first side wall is formed to be five times as long (width) as the thickness of the inner side walls 126 and 146 for the first side wall. This makes it easier for the operator to insert the first side wall engaging protrusions 128 and 148 into the first side wall engaging through hole 113. Further, in the container 180, the rigidity of the container 180 can be increased by the restoring force of the ruled lines 125 and 145 by the inner side walls 126 and 146 for the first side wall pressing the second inner piece 137. However, the width of the engagement through hole 113 for the first side wall may be formed to be a width into which the engagement protrusions 128, 148 for the first side wall can be inserted, and at least the engagement protrusions 128, 148 for the first side wall need to be formed. It suffices if it is formed to have a width equal to or greater than the plate thickness of.

Further, in the above embodiment, the width of the engagement through hole 114 for the second side wall is formed to be twice as long (width) as the thickness of the inner side wall 166, 176 for the second side wall. This makes it easier for the operator to insert the second side wall engaging protrusions 138 and 158 into the second side wall engaging through hole 114. Further, in the container 180, the second inner piece 137 presses the inner side wall 126, 146 for the first side wall via the inner side wall 166, 176 for the second side wall by the restoring force of the ruled lines 133a, 133b, 153a, 153b. The rigidity of the container 180 can be increased. However, the width of the engagement through hole 114 for the second side wall may be formed to be a width into which the engagement protrusions 138 and 158 for the second side wall can be inserted, and at least the engagement protrusions 138 and 158 for the second side wall need to be formed. It suffices if it is formed to have a width equal to or greater than the plate thickness of.

Further, in the above embodiment, the engagement protrusions 128, 148 for the first side wall and the engagement protrusions 138, 158 for the second side wall are formed to have a length penetrating the bottom plate 110. As a result, in the container 180, when the containers 180 are stacked, the first side wall engaging protrusions 128, 148 and the second side wall engaging protrusions 138, 158 projecting from the lower surface of the bottom plate 110 of the upper container 180 are provided.
