Furthermore, even if there are other effects that are different from the effects provided by the embodiments described below, those that are apparent from the description of the present specification or that can be easily predicted by those skilled in the art will naturally be included. It is understood that this is brought about by the present invention.

  In order to make the explanation clearer, the drawings may be schematically shown with respect to the width, thickness, shape, etc. of each part as compared to the actual embodiment, but are merely examples and limit the interpretation of the present invention. Not what you want.

  In the present specification and claims, when expressing a mode in which another structure is arranged on a certain structure, the expression “above” means that it touches a certain structure unless otherwise specified. In addition, both the case where another structure is arranged directly above and the case where another structure is arranged via another structure above a certain structure are included.

[1. External structure]
An external structure of a container 100 that is one embodiment of the present invention will be described with reference to FIGS. 1 (A), 1 (B), and 2. FIG. FIG. 1A is a perspective view seen from the front side of the container 100, and FIG. 1B is a perspective view seen from the back side. In these drawings, the container 100 is shown to have a substantially rectangular parallelepiped shape, but the three-dimensional shape of the container 100 is not limited, and may have, for example, a cubic shape.

  The container 100 includes an upper lid 110, a front plate 112, a first side plate 114, and a back plate 118. Although not illustrated in FIGS. 1A and 1B, the container 100 includes a bottom plate 120 that faces the top lid 110 and a second side plate 116 that faces the first side plate 114. As will be described later, the container 100 is formed by folding a single, integrated blank sheet 200. Therefore, the above-described components forming the outer structure of the container 100 and the respective components forming the inner structure of the container 100 described below are directly or indirectly connected to each other and formed in the blank sheet 200. Folds are distinguished as boundaries. The height H, length L, and depth D of the container 100 are the distance between the bottom plate 120 and the top lid 110, the distance between the first side plate 114 and the second side plate 116, and the distance between the front plate 112 and the back plate 118, respectively. Is defined as

  The front plate 112 may be provided with a perforation 130 as an arbitrary configuration. In this case, the perforation 130 has an open shape, and can be provided on the upper portion of the front plate 112 so that both ends of the perforation 130 reach one side closer to the upper lid 110 of the front plate 112. A finger hook can be formed by pushing an area 132 surrounded by one side of the perforation 130 and the upper lid 110 into the container 100 with a finger or the like, whereby the upper lid 110 is lifted and the container 100 is easily opened. It becomes possible.

  A perforation 134 may be provided on a part or the whole of the ridge between the back plate 118 and the second side plate 116. By separating the back plate 118 and the second side plate 116 along the ridge using the perforations 134, the container 100 can be easily disassembled. Further, a perforation 136 may be further provided on the back plate 118. The perforation 136 also has an open shape and can be provided so that both ends thereof reach the ridge. As a result, a region 138 surrounded by the ridge and the perforation 136 is formed. A finger hook is formed by pushing the region 138 into the container 100 with a finger or the like, and the back plate 118 and the second side plate 116 can be easily separated along the perforation 134. For this reason, the container 100 can be disassembled without requiring a great effort. Details of the dismantling operation will be described later. The shape of the perforations 130 and 136 can be arbitrarily determined, and may be a shape having a curve such as a semicircle or a semi-elliptical shape, or a shape having a straight line such as a square or a rectangle.

  FIG. 2 shows a schematic perspective view of the container 100 with the upper lid 110 opened. Upper flaps 114a, 116a, and 110a are connected to the upper portions of the first side plate 114, the second side plate 116, and the upper lid 110, respectively. A stored item is stored in a space 150 formed by the bottom plate 120, the front plate 112, the first side plate 114, the second side plate 116, and the back plate 118. The stored items are not particularly limited, and for example, a plurality of vials, ampoules, bottles or the like filled with liquid medicines or chemicals can be stored.

[2. Internal structure]
3 is a perspective view of the container 100, FIG. 4A is a top view of the internal structure provided in the space 150, and FIG. 4B is a cross-sectional view taken along the chain line AA ′ in FIG. 4A. A schematic diagram is shown. For ease of viewing, FIG. 3 shows a state where the second side plate 116 and the back plate 118 are separated. In the container 100, that is, in the space 150 (see FIG. 2), an internal structure for stably storing the stored items is formed. For example, in the space 150, a support plate 122 on the bottom plate 120, a first fixing plate 124 on the support plate 122, and a second fixing plate 126 on the first fixing plate 124 are provided. As shown in FIG. 4B, the bottom plate 120, the support plate 122, the first fixing plate 124, and the second fixing plate 126 are arranged so that their main surfaces are separated from each other. The stored items can be stored so that the bottom surface thereof is in contact with the support plate 122 and fits in the opening 152.

2-1. Fixing plate The first fixing plate 124 and the second fixing plate 126 are provided with openings 152. The opening 152 of the first fixing plate 124 overlaps the opening 152 of the second fixing plate 126. For this reason, the support plate 122 is observed through the opening 152 in the top view. A plurality of openings 152 may be provided, and the arrangement thereof is not limited. FIG. 3 shows an example in which 10 openings 152 are arranged on each of the first fixing plate 124 and the second fixing plate 126 in a matrix of 2 rows and 5 columns. The size and shape of the opening 152 can be appropriately determined based on the size and shape of the stored item. For example, the opening 152 may be a circle, an ellipse, or a polygon. In the case of a polygon, the inner corner may have a curved shape. When a plurality of openings 152 are provided, openings 152 having different sizes and shapes may be provided.

  FIG. 5A is a schematic cross-sectional view taken along the chain line BB ′ in FIG. As shown in FIG. 5A, the size (diameter d) of the opening 152 may be the same between the first fixing plate 124 and the second fixing plate 126. Alternatively, as shown in FIGS. 5B and 5C, the diameter d1 of the opening 152 of the first fixing plate 124 and the diameter d2 of the second fixing plate 126 may be different. In this case, the diameter d1 may be larger than the diameter d2 (FIG. 5B) or smaller (FIG. 5C). When the opening 152 having the same size and shape is provided in the first fixing plate 124 and the second fixing plate 126, the take-out direction of the stored item can be fixed in the normal direction of the bottom plate 120, and the stored item It is possible to prevent the container 100 from being damaged due to contact with an adjacent stored item when the container 100 is taken out, or the container 100 from falling. Further, even when the stored item is inclined in the opening 152, the inclination can be reduced, and contact between the stored items can be prevented when the container 100 is transported. As a result, the stored items can be safely stored and transported.

2-2. Support Plate As shown in FIG. 4A, the support plate 122 is provided with a cut 140. The notch 140 does not reach the side of the support plate 122 and forms an open shape in the plane of the support plate 122. Accordingly, the tab 142 is formed by the notch 140. A schematic cross-sectional view along the chain line CC ′ in FIG. 4 is shown in FIG. As shown in FIG. 6A, the tab 142 protrudes downward from a plane (first plane) where the support plate 122 excluding the tab 142 exists. The tab 142 can be divided into a first portion 142a and a second portion 142b with a bent portion as a boundary, and the first portion 142a is in contact with the upper surface of the bottom plate 120 at the bottom surface. The bottom surface of the first portion 142a may be fixed to the top surface of the bottom plate 120 with an adhesive. The contact surface between the first portion 142a and the bottom plate 120 has a closed shape that spreads two-dimensionally as shown in FIG. The second portion 142b connects the first portion 142a and the plane on which the support plate 122 exists. The second portion 142b does not exist in the same plane as the connecting portion 144 that connects the support plate 122 and the first fixing plate 124, but exists in a different plane.

  As shown in FIG. 6A, the second portion 142 b is separated from the main surface of the bottom plate 120. In a cross section parallel to the first side plate 114 and the second side plate 116, an angle θ between the surface of the second portion 142b and the bottom surface (or the first plane) of the support plate 122 excluding the tab 142. Can be arbitrarily set within a range larger than 0 ° and smaller than 180 °. In the example shown in FIG. 6A, the angle θ is 90 °. However, as shown in FIG. 6B and FIG. 6C, it may be smaller or larger than 90 °. Alternatively, the second portion 142b may have a zigzag shape as shown in FIG. 6D in the cross section, or may have a step shape as shown in FIG. 6E.

  As described above, the main surfaces of the bottom plate 120 and the support plate 122 are separated from each other via the tab 142. The tab 142 is in surface contact with the bottom plate 120 at the first portion 142a. Therefore, even if a plurality of heavy items are stored, the support plate 122 can be prevented from being bent by the weight. Furthermore, even if the support plate 122 bends due to the weight of the stored item, the second portion 142b falls down (that is, the angle θ becomes 0 ° or 180 °, and the surface of the second portion 142b becomes the surface of the support plate 122). It is possible to prevent the support plate 122 from contacting the bottom plate 120 (in contact with the bottom surface or the top surface of the bottom plate 120). Further, even when a large impact is applied to the container 100 from the outside, the second portion 142b functions as a cushioning material, and the impact can be converted into a deflection of the support plate 122 to be absorbed and alleviated. As a result, the impact received by the stored item can be greatly reduced, and damage to the stored item can be prevented.

  There are no restrictions on the number or shape of the notches 140 or tabs 142. Similarly, the number of support plates 122 is not limited. For example, as shown in FIG. 7A or a cross-sectional view thereof, FIG. 7B, two support plates 122a and 122b are provided between the bottom plate 120 and the first fixing plate 124 so as to overlap each other. A plurality of cuts 140 and 146 and tabs 142 and 148 may be provided in each of the support plates 122a and 122b. In this case, the tab 142 of the first support plate 122a is in contact with the bottom plate 120, and the tab 148 of the second support plate 122b is in contact with the first support plate 122a. By adopting such a structure, an external impact can be absorbed as the deflection of the first support plate 122a and the second support plate 122b, and the buffering effect can be further increased.

  The bottom plate 120, the support plate 122, the first fixing plate 124, and the second fixing plate 126 can have an asymmetric planar shape. For example, as shown in FIGS. 3 and 4A, the sides perpendicular to the length L direction of the bottom plate 120, the support plate 122, the first fixing plate 124, and the second fixing plate 126 (short sides 126a and 126b). The internal structure may be configured to have an asymmetric shape. Specifically, in at least one of the bottom plate 120, the support plate 122, the first fixing plate 124, and the second fixing plate 126, notches having different sizes (areas) are formed on the short side 126a and the short side 126b, respectively. Can be provided. In the example shown in FIG. 4A, the notch length (L1) of the short side 126a in the length L direction is larger than that (L2) of the short side 126b. Similarly, the notch length (D1) of the short side 126a in the depth D direction is larger than that (D2) of the short side 126b. Note that the area of the cutout of the short side 126a may be larger or smaller than that of the short side 126b. In the case where the region 138 is provided so as to be closer to the second side plate 116 than the first side plate 114, the area of the cutout of the short side 126a is preferably larger than that of the short side 126b. Conversely, when the region 138 is provided closer to the first side plate 114 than to the second side plate 116, the area of the cutout of the short side 126a is preferably smaller than that of the short side 126b.

[3. Manufacturing method]
The container 100 can be produced, for example, by folding a single blank sheet 200 shown in FIG. Paper can be used for the blank sheet 200. The basis weight of the paper can be selected from a range of 200 g / m ^{2 to} 600 g / m ² , 300 g / m ^{2 to} 550 g / m ² , or 400 g / m ^{2 to} 450 g / m ² .

  First, from the margin 202 to the upper flap 110a via the margins 204 and 206, the boundary between adjacent components is bent as a valley. The margin 202 and the margin 206, the margin 204 and the connecting portion 156, and the margin 206 and the back plate 118 may be fixed to each other using an adhesive or the like. The boundary between the upper flap 112a of the front plate 112 and the front plate 112 is also bent as a valley. These may be fixed to each other with an adhesive or the like. Thereafter, from the margin 208 to the second side plate 116, the boundary between adjacent components is bent as a valley. Similarly, boundaries between the first side plate 114 and the upper flap 114a, between the first side plate 114 and the lower flap 114b, between the second side plate 116 and the upper flap 116a, and between the second side plate 116 and the lower flap 116b. Also bend it as a valley. By the operation so far, the structure shown in FIG. 3 is obtained.

  Thereafter, the lower flap 114b and the bottom plate 120 of the first side plate 114 and the lower flap 116b of the second side plate 116 and the lower flap 112b of the front plate 112 are bonded to obtain the container 100 having the structure shown in FIG. It is done. At this time, as shown in the bottom view of FIG. 9A, the lower flap 114b of the first side plate 114, the lower flap 116b of the second side plate 116, and the lower flap 112b of the front plate 112 are positioned below the bottom plate 120. And overlaps the bottom plate 120.

[4. Collapse and unfold]
The container 100 can be transformed into a folded blank sheet 201. As shown in FIG. 9A, the bottom surface of the container 100 is formed by the lower flap 114b of the first side plate 114, the lower flap 116b of the second side plate 116, the lower flap 112b of the front plate 112, and the bottom plate 120. The By pushing this bottom surface in the direction of the space 150, as shown in FIG. 9B, the front plate 112 and the back plate 118 are displaced in the opposite directions while maintaining a parallel state to each other. The lower flap 114b, the lower flap 116b of the second side plate 116, the lower flap 112b of the front plate 112, and the bottom plate 120 are folded in the direction of the space 150. FIG. 10 shows a schematic top view at this time. The bottom plate 120, the lower flap 114b of the first side plate 114, the lower flap 116b of the second side plate 116, and the lower flap 112b of the front plate 112 jump in the direction of the space 150, and at the same time, the bottom plate 120, the support plate 122, the first plate The fixing plate 124 and the second fixing plate 126 are folded in the direction of the back plate 118 (in the direction of the arrow in FIG. 3) while being displaced in parallel with each other. Thereby, the folded blank sheet 201 which is one of the embodiments of the present invention is obtained (FIG. 11).

  FIG. 12 shows a schematic cross-sectional view along the chain line EE ′ of FIG. In the folded blank sheet 201, the bottom plate 120 and the support plate 122, the support plate 122 and the first fixing plate 124, the first fixing plate 124 and the second fixing plate 126, the second fixing plate 126 and the back plate 118. Can contact each other and can have a compact structure.

  When the folded blank sheet 201 is developed and deformed into the container 100, an operation reverse to the above operation may be performed. That is, the front plate 112 is pulled away from the bottom plate 120 from the state of FIGS. 11 and 12, and at the same time, the bottom plate 120, the support plate 122, the first fixing plate 124, and the second fixing plate 126 are pulled away from the back plate 118. A schematic diagram of the state during development is shown in FIG. Here, the front plate 112 and the second side plate 116 are not shown. The bottom plate 120, the support plate 122, the first fixing plate 124, and the second fixing plate 126 are rotated in the direction of the arrow in the figure with the ridge between the back plate 118 and the bottom plate 120 as an axis. This rotation is further continued, and the front plate 112, the back plate 118, the first side plate 114, and the second side plate 116 form a rectangular parallelepiped shape, thereby completing the deployment to the container 100.

  FIG. 14 shows a schematic top view of the container 100 during folding and deployment to the container 100. During the folding and unfolding operations, the front plate 112, the back plate 118, the first side plate 114, and the second side plate 116 are subjected to a force for maintaining a parallelogram shape. However, in the space 150, the bottom plate 120, the support plate 122, the first fixing plate 124, and the second fixing plate 126 rotate around the ridge between the back plate 118 and the bottom plate 120. Therefore, the first side plate 114 is in contact with one short side of the bottom plate 120, the support plate 122, the first fixing plate 124, and the second fixing plate 126 (see the region surrounded by a circle in FIG. 14). have a finger in the pie. As a result, the shape of the parallelogram cannot be maintained, and the first side plate 114 is folded and expanded while being curved.

  As described above, the container 100 can store, for example, a vial, an ampoule, a bottle, or the like filled with a liquid. However, depending on the capacity and size of the container 100, the weight of the stored item becomes considerably large. For this reason, relatively large physical strength is required for the support plate 122, the bottom plate 120, the front plate 112, and the back plate 118, and when the weight of the stored item is large, the blank sheet 200 is produced using paper with a large basis weight. Is done. In such a case, since the paper has high rigidity, the interference action by the first side plate 114 cannot be ignored, and a very large force is required at the time of folding and unfolding.

  However, as described above, notches are formed in the short sides of the bottom plate 120, the support plate 122, the first fixing plate 124, and the second fixing plate 126 to give an asymmetric structure with respect to an axis parallel to the depth D direction. be able to. For this reason, the bottom plate 120, the support plate 122, the first fixing plate 124, and the second fixing plate 126 are folded around the ridge between the back plate 118 and the bottom plate 120, and at the same time, the first side plate 114 is Each of the interference when folded with the ridge between the side plate 114 and the back plate 118 as an axis is reduced. As a result, a deformation operation between the folded blank sheet 201 and the container 100 can be easily performed.

[5. Dismantling]
The container 100 can be easily disassembled without requiring a large amount of labor, and can be quickly discarded or used for a recycling process. Specifically, an external force is applied to the region 138 shown in FIG. 1B using a finger or the like, and a finger hook is formed on a part of the back plate 118 along the perforation 136. Thereafter, the back plate 118 is separated from the second side plate along the perforation 134. The state at this time is shown in FIG. When the margin 208 and the second side plate 116 shown in FIG. 8 are bonded, the region 138 moves toward the second side plate 116 after the back plate 118 and the second side plate 116 are separated. Thereafter, as in the folding operation, the ridge between the bottom plate 120 and the back plate 118 is used as the rotation axis, and the bottom plate 120, the support plate 122, the first fixing plate 124, and the second fixing plate 126 are moved in the direction of the back plate 118 (arrows). Direction). By this operation, the container 100 can be deformed to a state substantially the same as the state shown in FIG.

  Also in this disassembly operation, the interference action by the first side plate 114 is reduced by the notches formed in the short sides of the bottom plate 120, the support plate 122, the first fixing plate 124, and the second fixing plate 126. For this reason, even if the container 100 is formed from the blank sheet 200 having a large basis weight, the container 100 can be disassembled by a simple operation.

  As described above, the container 100 can store a plurality of relatively heavy items such as vials and ampoules. Further, not only can the contact between stored items be suppressed even when an impact is applied from the outside, but also the contact between the support plate 122 and the bottom plate 120 is suppressed, or the impact at the time of contact between the support plate 122 and the bottom plate 120 is reduced. It has an internal structure that can For this reason, it is possible to safely store and transport the stored items. Furthermore, it can be easily manufactured from the integrated blank sheet 200, and does not have much labor for reversible deformation between the container 100 and the folded blank sheet 201. Further, the dismantling operation can be easily performed, and the cost required for disposal can be greatly reduced.

  In this embodiment, the results of a drop test of the container 100 in which a vial filled with a liquid is stored will be described.

[1. Experiment]
As the container 100, two types of containers (hereinafter referred to as containers 100a and 100b, respectively) formed from the blank sheet 200 shown in FIG. 8 were used. Although the structures of the containers 100a and 100b are the same, their sizes and basis weights are different. The height H, length L, and depth D of the container 100a were 62 mm, 164 mm, and 66 mm, respectively. The height H, length L, and depth D of the container 100b were 79 mm, 214 mm, and 86 mm, respectively. Ten openings 152 were formed in each of the first fixing plate 124 and the second fixing plate 126 of the containers 100a and 100b. In the container 100a, the diameter of the opening 152 was 23.5 mm, and that in the container 100b was 33.5 mm. The basis weight of the container 100a was 400 g / m ² , and the basis weight of the container 100b was 450 g / m ² .

  A schematic side view and a cross-sectional view of the vial 170 are shown in FIGS. 16 (A) and 16 (B). The vial 170 has a rubber plug 174, a socket 176, and a vial cap 178 at the opening of the glass main body 172, a label 180 at the body portion of the main body 172, and a pedestal 182 at the bottom of the main body 172. The rubber plug 174 has a function of sealing the liquid filled in the main body 172, whereby the contents can be collected through the syringe without opening the rubber plug 174. The vial cap 178 is made of polypropylene for protecting the rubber stopper 174 from being contaminated during storage and transportation. As the vial 170, two kinds of body capacities of 5 mL and 16.7 mL (hereinafter referred to as vials 170a and 170b, respectively) were used. Vials 170a and 170b were filled with approximately 5.1 g and 16.3 g of purified water, respectively. The weight of the vial 170a was 11.3 g. Therefore, the total weight of one vial 170a was 16.4 g. On the other hand, the weight of the vial 170b was 31.9 g. Therefore, the total weight of one vial 170b was 48.2 g.

  Vials 170a and 170b were stored in containers 100a and 100b, respectively. Each of the containers 100a and 100b accommodated ten vials 170a or 170b. After that, a sealing paper made of polyethylene terephthalate was stuck on the region 132 (see FIG. 1A) to seal the container 100, and covered with a urethane resin from a height of 1.0 m or 1.8 m. Free fall on the floor. The free fall was performed with the bottom plate 120, the first side plate 114, the front plate 112, or the upper lid 110 facing downward. That is, the container 100 was allowed to fall freely with the falling surface as the bottom plate 120, the first side plate 114, the front plate 112, or the upper lid 110. After free-falling, the container 100 was opened and the state of the vial 170 was visually observed.

[2. result]
Tables 1 and 2 show the results of a drop test from a height of 1.0 m and a drop test from a height of 1.8 m, respectively. In any drop test, regardless of the orientation of the container 100 before dropping, the body of the vial 170 was not damaged or cracked, and no leakage of purified water was observed. Also, no damage to the label 180 was observed. In the drop test from a height of 1.0 m, the vial cap 178 does not come off. In the drop test from a height of 1.8 m, when the front plate 112 and the upper lid 110 are directed downward, some of the vials 170 The vial cap 178 is only removed. Even when the vial cap 178 was removed, the rubber stopper 174 was not removed.

  From the above results, it was confirmed that by using the container 100 of the present embodiment, the glass vial filled with the liquid is not damaged even when dropped from a height of at least 1.8 m. This result shows that by using the container 100, a large amount of glass containers such as vials, ampoules and bottles, and chemicals and pharmaceuticals filled therein can be safely stored and transported.
