Furthermore, other effects different from those brought about by the embodiments described below, which are obvious from the description of the present specification or which can be easily predicted by those skilled in the art, will naturally be mentioned. It is understood to be brought about by the present invention.

The drawings may schematically represent the width, thickness, shape, etc. of each part as compared with the actual embodiment in order to clarify the explanation, but this is merely an example and the interpretation of the present invention is limited. It's not something to do.

In the present specification and claims, when expressing an aspect of arranging another structure on one structure, when the term "above" is simply used, the structure should be in contact with the structure unless otherwise specified. It is assumed that both the case where another structure is arranged directly above the structure and the case where another structure is arranged above the one structure via another structure are included.

[1. External structure]
The external structure of the container 100, which is one of the embodiments of the present invention, will be described with reference to FIGS. 1 (A), 1 (B), and 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 figures, 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 has an upper lid 110, a front plate 112, a first side plate 114, and a back plate 118. Although not shown in FIGS. 1A and 1B, the container 100 has a bottom plate 120 facing the top lid 110 and a second side plate 116 facing 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-mentioned components forming the external structure of the container 100 and the respective components forming the internal structure of the container 100 described below are directly or indirectly connected to each other and are formed in the blank sheet 200. The creases 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 of the front plate 112 on the side closer to the upper lid 110. A finger hook can be formed by pushing the 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.

Perforations 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 perforation 134, the container 100 can be easily disassembled. Further, the back plate 118 may be further provided with perforations 136. The perforation 136 also has an open shape, and both ends thereof can be provided so as to reach the ridge. As a result, the region 138 surrounded by the ridge and the perforation 136 is formed. By pushing this region 138 into the container 100 with a finger or the like, a finger hook is formed, and the back plate 118 and the second side plate 116 can be easily separated along the perforation 134. Therefore, the container 100 can be disassembled without requiring a large amount of labor. The 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 curved line 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 open. Upper flaps 114a, 116a, 110a are connected to the upper portions of the first side plate 114, the second side plate 116, and the upper lid 110, respectively. The stored items are stored in the 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, etc. 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 section taken along the chain line AA'of FIG. 4A. A schematic diagram is shown. In consideration of visibility, FIG. 3 shows a state in which the second side plate 116 and the back plate 118 are separated. Inside 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 object can be stored so that its bottom surface is in contact with the support plate 122 and fits in the opening 152.

2-1. Fixing Plate An opening 152 is provided in the first fixing plate 124 and the second fixing plate 126. The opening 152 of the first fixing plate 124 overlaps with the opening 152 of the second fixing plate 126. Therefore, in the top view, the support plate 122 is observed through the opening 152. 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 in a matrix of 2 rows and 5 columns on the first fixing plate 124 and the second fixing plate 126, respectively. The size and shape of the opening 152 can be appropriately determined based on the size and shape of the stored items. For example, the opening 152 may be circular, elliptical, or polygonal, and in the case of a polygon, its internal angle may have a curved shape. When a plurality of openings 152 are provided, openings 152 having different sizes and shapes may be provided.

FIG. 5 (A) shows a schematic cross-sectional view taken along the chain line BB'of FIG. 4 (A). 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. 5 (B)) or smaller (FIG. 5 (C)). When the openings 152 having the same size and shape are provided in the first fixing plate 124 and the second fixing plate 126, the taking-out direction of the stored object can be fixed in the normal direction of the bottom plate 120, and the stored object can be fixed. It is possible to prevent the container 100 from tipping over or being damaged by contacting with an adjacent stored object when it is taken out. Further, even when the stored items are tilted within the opening 152, the tilt can be reduced, and the stored items can be prevented from coming into contact with each other during transportation of the container 100. 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 notch 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. Therefore, the notch 140 forms the tab 142. A schematic cross-sectional view taken along the chain line CC'in FIG. 4 is shown in FIG. 6 (A). As shown in FIG. 6A, the tab 142 protrudes downward from the plane (first plane) where the support plate 122 excluding the tab 142 exists. The tab 142 can be distinguished 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 its bottom surface. The bottom surface of the first portion 142a may be fixed to the top surface of the bottom plate 120 by an adhesive. The contact surface between the first portion 142a and the bottom plate 120 has a two-dimensionally widened closed shape as shown in FIG. 4 (A). 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 connecting the support plate 122 and the first fixing plate 124, but exists in a different plane.

As shown in FIG. 6A, the second portion 142b is separated from the main surface of the bottom plate 120. 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 in a cross section parallel to the first side plate 114 and the second side plate 116. 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 °, but as shown in FIGS. 6B and 6C, it may be smaller or larger than 90 °. Alternatively, the second portion 142b may have a zigzag shape as shown in FIG. 6 (D) or a staircase shape as shown in FIG. 6 (E) in the cross section.

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. Then, the tab 142 comes into surface contact with the bottom plate 120 at the first portion 142a. Therefore, even if a plurality of heavy stored items are stored, it is possible to prevent the support plate 122 from bending due to the weight. Further, even if the support plate 122 is bent by the weight of the stored object, the second portion 142b is tilted (that is, the angle θ is 0 ° or 180 °, and the surface of the second portion 142b is the surface of the support plate 122. It is possible to prevent the support plate 122 from coming into contact with the bottom plate 120 (in contact with the bottom surface or the upper surface of the bottom plate 120). Further, even if a large impact is applied to the container 100 from the outside, the second portion 142b acts as a cushioning material, and the impact can be converted into the deflection of the support plate 122 to be absorbed and mitigated. As a result, the impact on the stored items can be significantly reduced, and damage to the stored items can be prevented.

There is no limit to the number or shape of the notches 140 and tabs 142. Similarly, there is no limit to the number of support plates 122. For example, as shown in FIG. 7A and FIG. 7B which is a cross-sectional view thereof, 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, and two support plates 122a and 122b are provided so as to overlap each other. A plurality of notches 140, 146 and tabs 142, 148 may be provided in each of the support plates 122a and 122b, respectively. 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, the impact from the outside can be absorbed as the deflection of the first support plate 122a and the second support plate 122b, and the cushioning 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 plane shape. For example, as shown in FIGS. 3 and 4 (A), the sides (short sides 126a, 126b) of the bottom plate 120, the support plate 122, the first fixing plate 124, and the second fixing plate 126 perpendicular to the length L direction. May configure the internal structure to have an asymmetrical shape. Specifically, at least one of the bottom plate 120, the support plate 122, the first fixing plate 124, and the second fixing plate 126 has notches having different sizes (areas) on the short side 126a and the short side 126b. Can be provided. In the example shown in FIG. 4 (A), the length (L1) of the notch on 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 of the short side 126b (D2). The area of the notch on the short side 126a may be larger or smaller than that on the short side 126b. When the region 138 is provided so as to be closer to the second side plate 116 than the first side plate 114, it is preferable that the area of the notch on the short side 126a is larger than that of the short side 126b. On the contrary, when the region 138 is provided so as to be closer to the first side plate 114 than the second side plate 116, the area of the notch on the short side 126a is preferably smaller than that of the short side 126b.

[3. Manufacturing method]
The container 100 can be manufactured, for example, by folding one 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 the range ^{of 200 g / m 2} or more and 600 g / m ² or less, 300 g / m ² or more and 550 g / m ² or less, or 400 g / m ² or more and 450 g / m ^{2 or less.}

First, the boundary between adjacent components is bent as a valley from the margin 202 to the upper flap 110a via the margins 204 and 206. 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 by 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 also be fixed to each other with an adhesive or the like. Then, from the margin 208 to the second side plate 116, the boundary between adjacent components is bent as a valley. Similarly, the boundary 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 fold as a valley. By the operations up to this point, the structure shown in FIG. 3 can be obtained.

Then, by adhering the lower flap 114b of the first side plate 114 and the bottom plate 120, and the lower flap 116b of the second side plate 116 and the lower flap 112b of the front plate 112, a container 100 having the structure shown in FIG. 2 is obtained. Be 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 located below the bottom plate 120. However, it overlaps with the bottom plate 120.

[4. Folding and unfolding]
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. To. By pushing the 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 opposite directions while maintaining a state of being parallel to each other, and at the same time, the first side plate 114 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. A schematic view of the upper surface at this time is shown in FIG. 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 up in the direction of the space 150, and at the same time, the bottom plate 120, the support plate 122, and the first The fixing plate 124 and the second fixing plate 126 of the above 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. As a result, a folded blank sheet 201, which is one of the embodiments of the present invention, can be obtained (FIG. 11).

A schematic cross-sectional view taken along the chain line EE'in FIG. 11 is shown in 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 touch each other and can have a compact structure.

When the folded blank sheet 201 is unfolded and transformed into the container 100, the operation opposite to the above operation may be performed. That is, the front plate 112 is separated from the bottom plate 120 from the states 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 separated from the back plate 118. A schematic diagram of the unfolded state 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 drawing about the ridge between the back plate 118 and the bottom plate 120. This rotation is further continued, and the development to the container 100 is completed by forming the shape of a rectangular parallelepiped by the front plate 112, the back plate 118, the first side plate 114, and the second side plate 116.

FIG. 14 shows a schematic top view of the container 100 during folding and unfolding into the container 100. During the folding and unfolding operations, a force acts on the front plate 112, the back plate 118, the first side plate 114, and the second side plate 116 to maintain the shape of the parallelogram. 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 about the ridge between the back plate 118 and the bottom plate 120. Therefore, the first side plate 114 comes into 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 circled area 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 unfolded 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, but the weight of the stored item becomes considerably large depending on the capacity and size of these. Therefore, the support plate 122, the bottom plate 120, the front plate 112, and the back plate 118 are required to have relatively large physical strength, and when the weight of the stored items is heavy, the blank sheet 200 is manufactured using paper having a large basis weight. Will be done. In such a case, since the rigidity of the paper is high, the interference action of 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 on the short sides of the bottom plate 120, the support plate 122, the first fixing plate 124, and the second fixing plate 126 to provide an asymmetric structure with respect to the axis parallel to the depth D direction. be able to. Therefore, the bottom plate 120, the support plate 122, the first fixing plate 124, and the second fixing plate 126 are folded about the ridge between the back plate 118 and the bottom plate 120, and at the same time, the first side plate 114 is first. Each interference when folding around the ridge between the side plate 114 and the back plate 118 is reduced. As a result, the 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 promptly discarded or used for a recycling process. Specifically, a force is applied from the outside to the region 138 shown in FIG. 1B by using a finger or the like to form a finger hook on a part of the back plate 118 along the perforation 136. The back plate 118 is then separated from the second side plate along the perforations 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 adhered to each other, the region 138 moves to the second side plate 116 side after the back plate 118 and the second side plate 116 are separated. After that, 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 directed toward the back plate 118 (arrows). Direction) Rotate. By this operation, the container 100 can be transformed into a state substantially the same as the state shown in FIG.

Also in this dismantling operation, the interference action by the first side plate 114 is reduced by the notches formed on the short sides of the bottom plate 120, the support plate 122, the first fixing plate 124, and the second fixing plate 126. Therefore, 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 storage items such as vials and ampoules. Further, not only the contact between the stored items can be suppressed even if an impact is applied from the outside, but also the contact between the support plate 122 and the bottom plate 120 can be suppressed, or the impact at the time of contact between the support plate 122 and the bottom plate 120 can be alleviated. It has an internal structure that can be used. Therefore, it is possible to safely store and transport the stored items. Further, it can be easily produced from the integrated blank sheet 200, and does not require much labor for reversible deformation between the container 100 and the folded blank sheet 201. In addition, the dismantling operation can be easily performed, and the cost required for disposal can be significantly reduced.

In this embodiment, the result of a drop test of a container 100 containing a vial filled with a liquid will be described.

[1. Experiment]
As the container 100, two types of containers formed from the blank sheet 200 shown in FIG. 8 (hereinafter, referred to as containers 100a and 100b, respectively) were used. The structures of the containers 100a and 100b are the same, but 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 the first fixing plate 124 and the second fixing plate 126 of the containers 100a and 100b, respectively. In container 100a, the diameter of the opening 152 was 23.5 mm, and in container 100b it 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 stopper 174, a socket 176, and a vial cap 178 in the opening of the glass body 172, a label 180 in the body portion of the body 172, and a pedestal 182 in the bottom of the body 172. The rubber stopper 174 has a function of sealing the liquid filled in the main body 172, whereby the contents can be collected via a syringe without opening the rubber stopper 174. The vial cap 178 is made of polypropylene and is intended to protect the rubber stopper 174 from contamination during storage and transportation. As the vial 170, two types having a main body volume 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 about 5.1 g and 16.3 g of purified water, respectively. The weight of the vial 170a was 11.3 g, and 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, and therefore the total weight of one vial 170b was 48.2 g.

Vials 170a and 170b were stored in containers 100a and 100b, respectively. Ten vials 170a or 170b were stored in each of the containers 100a and 100b, respectively. After that, a polyethylene terephthalate sealing paper was attached on the region 132 (see FIG. 1 (A)) to seal the container 100, and the container 100 was covered with a urethane resin from a height of 1.0 m or 1.8 m. I let it fall freely 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 freely dropped 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]
The results of the drop test from a height of 1.0 m and the drop test from a height of 1.8 m are shown in Tables 1 and 2, respectively. In any of the drop tests, there was no damage such as cracking or cracking of the main body of the vial 170 regardless of the orientation of the container 100 before dropping, and no leakage of purified water was observed. Also, no damage to label 180 was observed. In the drop test from a height of 1.0 m, the vial cap 178 did not come off, and in the drop test from a height of 1.8 m, some vials 170 when the front plate 112 and the upper lid 110 were turned downward. Vial cap 178 is only coming off. Even when the vial cap 178 was removed, the rubber stopper 174 did not come off.

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 if the container 100 is dropped from a height of at least 1.8 m. This result shows that by using the container 100, glass containers such as vials, ampoules and bottles, and the chemicals and medicines filled therein can be stored and transported in large quantities and safely.
