Description

  The present invention relates to a case in which an article is accommodated.

Cases (containers, boxes) are often used to transport various items.
A case having a heat insulating effect is used to carry the sheet while maintaining the cold state and the warm state.

Examples of conventional article storage cases include the following.
The article storage case has a bottom portion, a pair of first side wall portions facing each other, a pair of second side wall portions facing each other, and a lid portion. Each of them is formed by disposing a heat insulating material in a gap between a pair of front and back synthetic resin sheets.
The bottom has a rectangular shape. Each first side wall portion (the lower edge portion) is coupled to each short side of the bottom portion. Each second side wall portion (the lower edge portion) is coupled to each long side of the bottom portion. Adjacent first and second side wall portions (side edge portions) are also coupled to each other.
The lid portion (one edge portion) is provided so as to be openable and closable with respect to one second side wall portion (the upper edge portion).

  By the way, from the viewpoint of space saving, the article storage case is flat (that is, in a substantially flat state) in a state where no article is stored (that is, an empty state). Is desirable.

However, the above-described article storage case is not formed on the assumption that it is substantially flat (flattened).
For this reason, when trying to flatten, each first side wall portion is bent inward along a center line extending in the height direction at the center in the width direction, and the bottom portion is defined as a long side at the center in the short side direction. It is only crushed by folding along a parallel center line.
However, this work is complicated.

On the other hand, there is also an article storage case formed on the assumption that it is substantially flat (folded or the like).
The article storage case has a bottom portion, a pair of first side wall portions facing each other, a pair of second side wall portions facing each other, and a lid portion, in substantially the same manner as the above-described article storage case.
Each first side wall and each second side wall are provided so as to be rotatable with respect to each side of the bottom at the lower edge (base edge). That is, each first side wall portion and each second side wall portion are in an upright posture that is substantially perpendicular to the bottom portion and upward from the bottom portion, a folded posture that is tilted inward and overlaps with the bottom portion (inclined posture inward), and Alternatively, it is possible to displace between an outwardly extending posture (falling posture toward the outside) that tilts outward and forms substantially the same plane as the bottom.

And in the state which each 1st side wall part and each 2nd side wall part became the standing posture, the adjacent 1st side wall part and the 2nd side wall part (its side edge part) are the surface fasteners provided in each ( The first side wall and the second side wall are maintained in the standing posture by being detachably coupled by the male / female.
Note that the state in which all the side wall portions are in the standing posture is referred to as a basic state of the article storage case.

On the other hand, when the article storage case is not in use (that is, in a state in which no article is stored), the adjacent first side wall and second side walls are separated from each other and placed in an overturned posture, and are substantially flat as a whole. It becomes a state.
In addition, the state in which all the side wall portions are in the inclined posture and are substantially flat as a whole is referred to as a substantially flat state of the article storage case.
Moreover, let the state in which all the side wall parts are the inclining attitude | position (folding attitude | position) to the inner side among the substantially planar states be a folded state of an article | item storage case.
And when this article storage case is going to be used, the phase is changed from a substantially planar state to a basic state. Thus, the article is stored in the storage space formed inside.

However, in the above-described article storage case, in order to change the phase from the substantially planar state to the basic state, it is necessary to displace each first side wall and each second side wall from an inverted posture to a standing posture. Then, the adjacent first side wall part and the second side wall part are connected to each other by a surface fastener (male / female) while being positioned in a predetermined positional relationship (both standing postures), and are maintained in a basic state. It is necessary to do so.
That is, in the article storage case, in order to change the phase from the substantially planar state to the basic state, it is necessary to operate all the side wall portions and displace them toward the standing posture, which is complicated.
In addition, adjacent first side wall portions and second side wall portions need not be simply coupled by a hook-and-loop fastener, but are coupled in a predetermined positional relationship (while maintaining them in a standing posture). The work is also complicated.

Moreover, it is desirable that the article storage case has a waterproof property (a liquid leakage preventing effect). That is, for example, even if it is not assumed that the liquid is stored as it is (that is, in an unwrapped state), a container containing the liquid may be stored, and even if the liquid leaks from the container, It is desirable that liquid does not leak from the article storage case.
When a container containing a cold liquid is stored, condensation may occur on the surface of the container, and it is desirable that the liquid (water) generated in this way does not leak from the article storage case.

  In the technical field to which the present invention belongs, there are also prior arts disclosed in Patent Document 1 and Patent Document 2.

Moreover, this invention makes it the 2nd subject to provide the articles | goods storage case which has a liquid leak prevention effect further.

In order to solve this problem, an invention according to claim 1 is an article storage case in which an article is stored in an inner storage space, and stands up in a direction having a rectangular bottom portion and a vertical component from the bottom portion. A pair of first side wall portions that are displaceable between a standing posture and a folded posture that is folded inward and overlapped with the bottom portion, and that are opposed to each other in the state of the standing posture, and perpendicular to the bottom portion It is possible to displace between a standing posture standing up in a direction having a component and an outward extending posture extending outward while falling outward and forming substantially the same plane as the bottom. A case body having a pair of second side wall portions facing each other in a state, and an inner sheet disposed inside the case body, wherein the inner sheet corresponds to the bottom portion, and More than midway height of the first side wall A line composed of a line extending in a direction having a longitudinal component of the first side wall portion at the height position and a line extending from the first side wall portion, and the first position at a height position equal to or higher than a midway height of the pair of second side wall portions. Two side walls extending in a direction having a length direction component and a line formed by extending the same, and the inner sheet has the first side wall of each of the first side walls. A pair of folding portions are formed that are folded inwardly in accordance with the folding posture of each first side wall portion with respect to the bottom portion, along a folding line corresponding to a line composed of a base edge portion and a line extending from the base edge portion. The portion corresponding to each first side wall portion of each of the folded portions is coupled to the first side wall portion, and the first portion of the portions corresponding to the second side wall portions of the respective folded portions. 2 side wall Portions corresponding to the side of the upper portion is coupled to the second side wall portion, an article housing case.

The “rectangular shape” includes a rectangular shape and a square shape. The same applies to the inventions according to other claims.
“A height position equal to or higher than the mid-side height of the first side wall portion / the second side wall portion” is an expression based on a state where the first side wall portion / the second side wall portion is in the standing posture. The same applies to the “upper edge portion of the second side wall portion”.
“A portion corresponding to each first side wall portion among the respective folded portions is coupled to the first side wall portion” means “a portion corresponding to each first side wall portion among the respective folded portions”. In addition to a mode in which all of the portions are coupled to the first side wall portion, a part of “the portion corresponding to the first side wall portion among the folded portions” is the first portion. A mode of being coupled to the side wall is also included.

In the article storage case of the present invention, the following effects can be obtained.
First, in this article storage case, in a state where both the pair of first side wall portions and the pair of second side wall portions are in the standing posture, a storage space is formed inside thereof, and an article can be stored in the storage space. As described above, the state in which the pair of first side wall portions and the pair of second side wall portions are in the standing posture is referred to as a basic state of the article storage case.
On the other hand, the article storage case is substantially flat when the pair of first side wall portions are in the folded posture and the pair of second side wall portions are in the outwardly extending posture. This state is referred to as an outwardly extended state (one of substantially planar states) of the article storage case.
For this reason, in the case of non-use, space saving is achieved by being in a folded and unfolded state (substantially flat state).
The same applies to the inventions related to other independent claims.

Moreover, in the article storage case of the present invention, the inner sheet is disposed on the inner side. The inner sheet corresponds to the bottom, and extends in a direction having a longitudinal component of the first side wall at a height position equal to or higher than the middle height of the pair of first side walls, and a line extending the same. And a line consisting of a line extending in a direction having a longitudinal component of the second side wall part and a line extending from the line at a height position equal to or higher than the middle height of the pair of second side wall parts. At least approximately rectangular.
That is, when the article storage case is in the basic state, the inner sheet corresponds to the bottom, and the upper edge thereof is at a height position equal to or higher than the middle height of the pair of first side walls and the pair of second side walls. Located at a height above the midway height of the section.
For this reason, when this inner sheet has a property of not allowing liquid to permeate, a liquid leakage preventing effect (waterproofness) is obtained.
That is, even when a liquid in an unwrapped state is generated inside the article storage case, such as when the liquid stored in the container flows out of the container inside the article storage case, the liquid is outside the inner sheet. The liquid is prevented from flowing out and the liquid is prevented from leaking outside the article storage case.

Further, in the article storage case of the present invention, the inner sheet is formed with a pair of folding portions that are folded inward along the pair of folding lines, and a portion corresponding to each first side wall portion of each folding portion. Are coupled to the first side wall portion, and a portion corresponding to the second side wall portion of each folded portion corresponds to an upper edge portion side of the second side wall portion with respect to the second side wall portion. Are combined.
Thus, each first side wall portion and each second side wall portion are a portion corresponding to the first side wall portion and a second side wall portion among the portions corresponding to the second side wall portion among the folded portions of the inner sheet. It is substantially connected by a portion (this portion is referred to as a substantially connecting portion) between the portions corresponding to the upper edge side.

For this reason, this article storage case is in a folded and unfolded state (one pair of first side wall portions is in a folded posture and a pair of second side wall portions are in an outward extending posture), which is one of the substantially planar states. In some cases, the pair of first side wall portions are operated so as to be displaced from the folded posture (inwardly tilted posture) toward the standing posture, and the inner sheet (of which the substantial connecting portion) is moved. Accordingly, the pair of second side wall portions can be displaced from the outward extending posture (the outwardly inclined posture) toward the standing posture.
Thus, the article storage case can be in a basic state (a pair of first side wall portions and a pair of second side wall portions are in a standing posture) from a substantially flat state.
Thus, in the article storage case of the present invention, it is not necessary to operate the pair of first side wall portions and the pair of second side wall portions so as to be displaced from the lying down posture toward the standing posture. The phase can be easily changed from the planar state (folded and unfolded state) to the basic state.
That is, the article storage case of the present invention can be made compact as a substantially flat state (folded and unfolded state) when not in use, and can be easily brought into a basic state when used. is there.

The invention according to claim 2 is an article storage case in which articles are stored in an inner storage space, and has a rectangular bottom portion, a standing posture standing up in a direction having a vertical component from the bottom portion, and an inwardly falling side. A pair of first side wall portions that are displaceable between the folding postures that overlap the bottom portion and are opposed to each other in the standing posture, and a stand that stands up in a direction having a vertical component from the bottom portion. It is possible to displace between a posture and an outwardly extending posture that extends outward while tilting outward and forming substantially the same plane as the bottom, and facing each other in the standing posture state A case main body having a second side wall and an inner sheet disposed inside the case main body, wherein the inner sheet corresponds to the bottom and has upper edges of the pair of first side walls. A straight line extending along the section and extending it A straight line formed of a straight line, a straight line extending along the upper edge of the pair of second side wall portions, and a straight line formed of a straight line extending the straight line, and the inner sheet includes: The first side wall portion is folded inward along the folding line corresponding to the base line of the first side wall portion and a line extending from the first side wall portion, corresponding to the folding posture of the first side wall portion with respect to the bottom portion. A pair of folded portions is formed, and a portion of each folded portion corresponding to an upper edge portion of each first side wall portion is coupled to an upper edge portion of the first side wall portion, and among the folded portions, In the article storage case, a portion corresponding to the upper edge portion of each second side wall portion is coupled to the upper edge portion of the second side wall portion.

  The “first sidewall portion / the upper edge portion of the second sidewall portion” is an expression based on a state in which the first sidewall portion / second sidewall portion is in a standing posture.

In the article storage case according to the present invention, substantially the same effect as that of the invention according to claim 1 can be obtained. A more reliable effect than that of the invention according to claim 1 can be obtained.

That is, first, in the article storage case of the present invention, the inner sheet is disposed inside. The inner sheet corresponds to the bottom, and is formed on a straight line extending along the upper edge of the pair of first side walls and a straight line extending the same, and on the upper edges of the pair of second side walls. It has a rectangular shape formed by a straight line extending along and a straight line formed by extending the straight line.
That is, when the article storage case is in the basic state, the inner sheet corresponds to the bottom portion, and the upper edges thereof are the upper edge portions of the pair of first side wall portions and the upper edge portions of the pair of second side wall portions. Located in.
For this reason, when this inner sheet has a property of not allowing liquid to permeate, a liquid leakage preventing effect (waterproofness) is obtained.
That is, even when a liquid in an unwrapped state is generated inside the article storage case, such as when the liquid stored in the container flows out of the container inside the article storage case, the liquid is outside the inner sheet. The liquid is prevented from flowing out and the liquid is prevented from leaking outside the article storage case.

In the article storage case of the present invention, the inner sheet is formed with a pair of folding portions that are folded inward along the pair of folding lines, and the upper edge portion of each first side wall portion of each folding portion. And a portion corresponding to the upper edge portion of each second side wall portion of each folded portion with respect to the upper edge portion of the second side wall portion. Are combined.
Thus, each first side wall portion and each second side wall portion is a portion corresponding to the upper edge portion of each first side wall portion of each folded portion of the inner sheet (on the upper edge portion of the first side wall portion). (The end of which is connected) and the portion corresponding to the upper edge of each second side wall (connected to the upper edge of the second side wall) (the end thereof) Are substantially connected by a portion to be connected (this portion is called a substantially connecting portion).

For this reason, this article storage case is in a folded and unfolded state (one pair of first side wall portions is in a folded posture and a pair of second side wall portions are in an outward extending posture), which is one of the substantially planar states. In some cases, the pair of first side wall portions are operated so as to be displaced from the folded posture (inwardly tilted posture) toward the standing posture, and the inner sheet (of which the substantial connecting portion) is moved. Thus, the pair of second side wall portions are displaced from the outwardly extending posture (outwardly inclined posture) toward the standing posture.
Thus, the article storage case changes from a substantially flat state to a basic state (a pair of first side wall portions and a pair of second side wall portions are in a standing posture).
Thus, in the article storage case of the present invention, it is not necessary to operate the pair of first side wall portions and the pair of second side wall portions so as to be displaced from the lying down posture toward the standing posture. The phase can be easily changed from the planar state (folded and unfolded state) to the basic state.
That is, the article storage case of the present invention can be made compact as a substantially flat state (folded and unfolded state) when not in use, and can be easily brought into a basic state when used. .

The invention according to claim 3 is the article storage case of the invention according to claim 1 or claim 2 , wherein the first side wall portion is displaced from the folded posture toward the standing posture, and the second side wall portion. A binding material that removably couples the folded portions of the inner sheet that are close to or in contact with each other as it is displaced from the outwardly extending posture toward the standing posture. This is an article storage case provided.

In the article storage case of this invention, in addition to the effects of the article storage case of the invention according to claim 1 or claim 2 , the following effects can be obtained.
That is, in this article storage case, the portions that are close to or in contact with each other among the folded portions of the inner sheet due to the phase change from the folded unfolded state toward the basic state are caused by the binder. By being combined, both the first side wall and the second side wall are maintained in the standing posture.
In this way, the article storage case is easily maintained in the basic state.

The invention according to claim 4 is the article storage case of the invention according to any one of claims 1 to 3 , wherein the pair of first side wall portions are in the folded posture, The pair of second side wall portions is an article storage case that is displaceable between the outwardly extending posture and a folded posture that is folded inward and overlaps the bottom portion.

In the article storage case of the present invention, the following operational effects are obtained in addition to the operational effects of the article storage case of the invention according to claims 1 to 3 .
That is, in this article storage case, from a folded and unfolded state that is one of the substantially planar states (a pair of first side wall portions is in a folded posture and a pair of second side wall portions is in an outwardly extending posture). The pair of second side wall portions can be displaced from the outwardly extending posture to the folded posture (overlapping the bottom portion with the first side wall portion interposed therebetween).
As described above, the state in which the pair of first side wall portions and the pair of second side wall portions are folded is referred to as a folded state of the article storage case (another one in a substantially planar state).
For this reason, in this article storage case, when not in use, it can be made more compact by being folded.

That is, the substantial connection part 90 is a part corresponding to the folded second side wall part corresponding part 88 in the short side of the inner sheet 60.
It can be said that each first side wall portion 30 and each second side wall portion 40 are substantially connected by a substantial connecting portion 90 of the inner sheet 60. That is, the substantial connecting portion 90 of the inner sheet 60 is a portion that also functions as the connecting material of the present invention.

As shown in FIGS. 1 and 2, even when the article storage case is in the basic state, the inner sheet 60 is placed on the case body 10 (its bottom portion 20, each first side wall portion 30, and each second side wall portion 40). Along.
That is, the portion corresponding to the bottom portion 20 is substantially horizontal as in the case where the article storage case is folded and unfolded, and the portion corresponding to each first side wall portion 30 extends along each first side wall portion 30. The portion corresponding to each second side wall portion 40 is substantially vertical along each second side wall portion 40.
At that time, each folded second side wall portion corresponding portion 88 of the inner sheet 60 is folded along the folding line 82 to form a two-layered shape, and the central portion 70 (second portion of the inner sheet 60). It corresponds to each 2nd side wall part 40 with the part corresponding to the side wall part 40 (refer also FIG.5, FIG.6, FIG.7A-FIG.7E).
That is, in that portion, the inner sheet 60 is in a three-layered shape in total.

As shown in FIGS. 4 to 6, FIG. 7A and the like, the folded second sidewall portion corresponding portion 88 corresponding to the non-continuous second sidewall portion 40 </ b> A in the folded portion 80 of the inner sheet 60 is as follows. The surface fastener (male) 84 (binding material) and the surface fastener (female) 94 (binding material) are attached symmetrically with respect to the bending line 82 (with the bending line 82 interposed).
The hook-and-loop fastener (male) 84 has left and right portions in the upper part of the non-continuous second side wall part 40A (upper part in the state of standing non-continuous second side wall part 40A) among the folded second side wall part corresponding parts 88. It is attached to the part corresponding to the end.
The surface fastener (female) 94 corresponds to the upper edge portion of the front surface of the first side wall portion 30 (the first side wall portion 30 in the upright posture state) of each substantially connecting portion 90. Each is attached in the vicinity of the upper edge of the front surface).

Next, a method for using the article storage case will be described.
First, an outline of the usage method will be described.
As shown in FIGS. 1 to 3, the article storage case is used in a basic state.
The basic state is a state in which the article storage case has a substantially rectangular parallelepiped shape (this is described above). That is, the basic state is that the pair of first side wall portions 30 and the pair of second side wall portions 40 of the case body 10 are in an upright posture, and the side edge portions of the adjacent first side wall portions 30 and the respective second side portions. The side edge portion of the side wall portion 40 is at least substantially coincident.
At that time, the inner sheet 60 is in a state along the case main body 10 (the upper surface of the bottom portion 20, the inner surface of each first side wall portion 30, the inner surface of each second side wall portion 40) inside the case main body 10. .
In that state, the upper edge of the inner sheet 60 (the edge part forming the long side and the short side of the inner sheet 60 in the unfolded state) is the upper edge part of each first side wall part 30 and each second side wall part 40. Position (match).

And in the basic state (a state in which the lid 50 is opened), various articles are accommodated therein. At this time, if the connecting pieces 32 are previously set in the same plane posture (substantially vertical posture) or a state close thereto (see FIG. 7E), the housing operation can be performed more efficiently.
After the accommodation operation is finished, the lid 50 is closed as shown in FIGS.
That is, each surface fastener (male) of the lid portion 50 (lid body portion 51) in a state where the coupling piece 32 of each first side wall portion 30 is in a bent posture (a substantially horizontal posture inward) (FIG. 1). 53 is coupled to the surface fastener (female) 33 of the coupling piece 32 of each first side wall 30. At the same time, the surface fastener (male) 54 of the bent portion 52 of the lid 50 is coupled to the surface fastener (female) 44 of the non-continuous second side wall portion 40A. Thus, the article storage case is closed (FIG. 3).
This article storage case is transported in this closed state.

On the other hand, when the article is not accommodated (after the article accommodated so far is taken out), the article accommodation case is in a folded and unfolded state (FIG. 4) or a folded state (FIG. 8B).
That is, in any case, first, the article storage case is in a folded and unfolded state (FIG. 4). As shown in FIGS. 4 and 5, the folded and unfolded state is a state in which the pair of first side wall portions 30 are in the folded posture and the pair of second side wall portions 40 are in the outwardly extending posture.

From this state, a folded state (FIG. 8B) is set as necessary.
That is, as shown in FIG. 8A, the substantially flat second side wall portion 40B and the lid portion 50 are substantially center lengths as imaginary lines (length (distance) from the bottom portion 20). In FIG. 8B, it is bent along a straight line extending in parallel with the long side of the bottom portion 20 (two-dot chain line → solid line), and overlapped with the bottom portion 20 as shown in FIG.
In this state, as shown in FIG. 8B, the surface fastener (male) 28 of the coupling piece 27 is coupled to the surface fastener (female) 58 of the lid 50 (two-dot chain line → solid line).
Thus, a compact folded state (FIG. 8B) can be obtained.
That is, the folded state is a state in which the pair of first side wall portions 30 and the pair of second side wall portions 40 are in a folded posture.

Next, the details of the above usage method and the operation of the article storage case will be described.
An operation for changing the phase of the article storage case from the folded and unfolded state (FIG. 4) to the basic state (FIG. 1) will be described.
As shown in FIG. 4 → FIG. 7A → FIG. 7B → FIG. 7C, an operator grips the pair of first side wall portions 30 (gripping portions 35) in the folded posture, and the pair of first side wall portions in the folded posture. 30 is displaced toward the standing posture.
In that case, since each 1st side wall part 30 and each 2nd side wall part 40 are connected via the substantial connection part 90 of the inner sheet | seat 60, each 1st side wall part 30 changes from a folding attitude | position to an upright attitude | position. Along with the displacement, the second side wall portions 40 are also displaced from the outward extending posture toward the standing position.

That is, as the first side wall portion 30 tends to be displaced from the folded posture toward the standing posture, the folded second side wall portion corresponding portion 88 of each inner sheet 60 is being folded along the folding line 82. The portion on the first side wall portion 30 side with respect to the folding line 82 in the folded second side wall portion corresponding portion 88 is the second side wall portion 40 (the second side wall portion in the central portion 70 of the inner sheet 60). The part corresponding to 40).
Along with this, the second side wall portion 40 is displaced from the outward extending posture toward the standing posture so as to be pulled by the substantial connecting portion 90 (the working portion 81 thereof).

  Thus, as shown in FIG. 7C, each of the first side wall portions 30 and each of the second side wall portions 40 are positioned in a posture close to the standing posture, and the pair of first side wall portions 30 in a posture close to the standing posture. (The side edge portion) and each second side wall portion 40 (the side edge portion) in a posture close to the standing posture are close to each other.

Accordingly, as shown in FIG. 7C, on the non-continuous second side wall portion 40A side, each surface fastener (male) 84 and each surface fastener of the inner sheet 60 (folded second side wall portion corresponding portion 88). The (female) 94 comes close to each other in a facing state.
From that state, as shown in FIG. 7C → FIG. 7D, each surface fastener (male) 84 and each surface fastener (female) 94 of the inner sheet 60 are combined.
In this way, the pair of first side wall portions 30 are substantially in the standing posture, the non-continuous second side wall portion 40A is also in the standing posture, and the pair of first side wall portions 30 in the substantially standing posture (the non-continuous second wall portion 30). 2 side wall portion 40A side edge) and the non-continuous second side wall portion 40A in the standing posture (its side edge portion) at least substantially coincide with each other.

Similarly, as shown in FIGS. 7D to 7E, a pair of first side wall portions 30 (side edges thereof) in a posture close to a standing posture and each second side wall portion 40 (in that side) in a posture close to the standing posture. As the edge portion comes close, on the side of the continuous second side wall portion 40B, each surface fastener (female) of each coupling piece 55 and inner sheet 60 (folded second side wall portion corresponding portion 88). ) 96 approaches.
From this state, each coupling piece 55 is set in a folded posture, and the surface fastener (male) 56 of each coupling piece 55 is coupled to each surface fastener (female) 96 of the inner sheet 60.
In this way, the pair of first side wall portions 30 are both in the standing posture, the continuous second side wall portion 40B is also in the standing posture, and the pair of first side wall portions 30 (the continuous second side wall portion 40B in the standing posture). Side edge part) and the continuous second side wall part 40B in the standing posture (the side edge part) at least substantially coincide with each other.

  As described above, the article storage case changes phase from the folded and unfolded state (FIG. 4) to the basic state (FIGS. 1 and 7E).

Further, by performing an operation reverse to the above, the article storage case changes from the basic state (FIGS. 1 and 7E) to the folded and unfolded state (FIG. 4).
That is, as shown in FIG. 7E → FIG. 7D (→ FIG. 7C), the surface fastener (male) 56 of each coupling piece 55 is removed from each surface fastener (female) 96 of the inner sheet 60 to continuously connect the second side wall portion 40B. And the first side wall portions 30 are separated, and the continuous second side wall portions 40B are displaced from the standing posture toward the outward extending posture (see FIG. 7C).
At the same time, as shown in FIG. 7D → FIG. 7C, the respective side fasteners (male) 84 of the inner sheet 60 and the respective surface fasteners (female) 94 of the inner sheet 60 are separated to form the non-continuous second side wall portion 40A. Each second side wall 40 is separated, and the non-continuous second side wall 40A and the continuous second side wall 40B are changed from the standing posture to the outward extending posture as shown in FIGS. Displace towards.
Accordingly, as shown in FIG. 7C → FIG. 7B → FIG. 7A → FIG. 4, the first side wall portions 30 are displaced from the standing posture toward the folded posture via the substantial connecting portion 90 of the inner sheet 60. To do.
As described above, the article storage case changes phase from the basic state (FIGS. 1 and 7E) to the folded and unfolded state (FIG. 4).

As described above, the article storage case can be easily phase-shifted from the folded and unfolded state (substantially flat state) to the basic state.
That is, as the first side wall portion 30 is displaced from the folded posture toward the standing posture, the second side wall portion 40 is also automatically displaced from the outward extending posture toward the standing posture. It is not necessary to operate the side wall portion 30 and the second side wall portion 40 to be displaced toward the standing posture, and the phase can be easily changed from the folded and unfolded state (substantially flat state) to the basic state.

Conversely, the article storage case can be easily phase-shifted from the basic state to the folded and unfolded state (substantially flat state).
That is, as the second side wall portion 40 is displaced from the standing posture toward the outward extending posture (outwardly inclined posture), the first side wall portion 30 is also automatically folded from the standing posture (inner side). Therefore, it is not necessary to operate the first side wall 30 and the second side wall 40 respectively to move toward the tilted posture, and it is easily folded and unfolded from the basic state. The phase can be changed to a state (substantially planar state).

When trying to change the phase of the article storage case from the folded and unfolded state to the basic state, as shown in FIG. 7C, the pair of first side wall portions 30 and the non-continuous second side wall portion 40A are also in the standing posture. By being positioned in a close posture, the respective surface fasteners (male) 84 and the respective surface fasteners (female) 94 of the inner sheet 60 to be joined to maintain both in an upright posture are close to each other in an opposing state. Become. For this reason, as shown in FIG. 7C → FIG. 7D, each surface fastener (male) 84 and each surface fastener (female) 94 can be easily coupled.
Similarly, as shown in FIG. 7D, the pair of first side wall portions 30 and the continuous second side wall portion 40B are coupled to maintain both of them in the standing posture by being positioned in a posture close to the standing posture. The respective connecting pieces 55 and the respective surface fasteners (female) 96 come close to each other. For this reason, as shown in FIG. 7D → FIG. 7E, the surface fastener (male) 56 and each surface fastener (female) 96 of each coupling piece 55 can be easily coupled.
Thus, in this article storage case, each first side wall portion 30 and each second side wall portion 40 can be easily maintained in a standing posture and easily maintained in the basic state.
In this respect as well, the article storage case can be easily phase-shifted from the folded and unfolded state (substantially flat state) to the basic state.

Further, as described above, in this article storage case, the inner sheet 60 is disposed inside the case body 10. The inner sheet 60 is impermeable to liquid and is formed of a single sheet. Further, the inner sheet 60 corresponds to all of the bottom portion 20 (the upper surface thereof), both the first side wall portions 30 (the inner surface thereof), and both the second side wall portions 40 (the inner surface thereof) (covers all of them). ).
For this reason, even when a liquid such as water is generated inside the article storage case (that is, inside the inner sheet 60), the liquid is prevented from leaking to the outside.
That is, for example, a container such as a bottle containing a liquid such as beverage or blood (due to blood donation) is accommodated in the article storage case, and even if the liquid flows out of the container, The liquid is prevented from leaking to the outside (outside the article storage case).
In addition, since the article storage case (case body 10) has a heat insulating property (this is described above), there is a heat insulating / cooling effect, and a container storing a low temperature liquid may be stored. In such a case, condensation may occur on the outer surface of the container. However, the water thus generated is also prevented from leaking outside by the inner sheet 60.

  Thus, in this article storage case, the inner sheet 60 contributes to preventing liquid leakage, and the substantial connecting portion 90 of the inner sheet 60 includes the first side wall 30 and the second side wall 40. And the second side wall 40 is displaced from the outwardly extended posture to the standing posture in accordance with the displacement of the first side wall portion 30 from the folded posture to the standing posture, and the second side wall portion 40. This is also contributing to displacing the first side wall portion 30 from the standing posture to the folding posture in accordance with the displacement from the standing posture to the outward extending posture.

[Reference example]
Next, a reference example of the present invention will be described based on FIGS. 9 to 13B with a focus on differences from the embodiment. Each element corresponding to each element in the embodiment is given a corresponding code (a code obtained by adding “100”), and the description thereof is omitted as appropriate.

This article storage case is different from the embodiment in that it does not have an inner sheet (60).
This article storage case can change phase between a basic state (FIGS. 9 and 10) having a rectangular parallelepiped shape and a folded and unfolding state (substantially flat state) (FIGS. 11 and 12) having a substantially flat state. .

  As shown in FIGS. 9 to 12, the article storage case includes a bottom portion 120, a pair of opposing first side wall portions 130, a pair of opposing second side wall portions 140, a lid portion 150, and four pairs of connecting members. 190.

  In the basic state (FIG. 9), the adjacent first side wall portions 130 (the side edge portions) and the second side wall portions 140 (the side edge portions) thereof are not limited to the basic state (FIG. 11). Even in the state (FIG. 9), they are not directly coupled.

As shown in FIG. 9 to FIG. 11, FIG. 13A, and FIG. 13B, each first side wall 130 is formed on each short side (one pair of edges) of the bottom 120 at its lower edge (base edge). It is coupled so as to be rotatable.
Each first side wall 130 can be displaced between a standing posture (FIG. 9) and a folded posture (FIG. 11).

As shown in FIGS. 9 to 12 and the like, the lid 150 has a lid main body 151 and a bent portion 152. The lid 150 is connected to one second side wall 140.
The second side wall part 140 not provided with the lid part 150 is referred to as a non-continuous second side wall part 140A, and the second side wall part 140 provided with the lid part 150 is provided continuously. The two side wall portions 140B are assumed.

As shown in FIGS. 9 to 11, 13 </ b> A, and 13 </ b> B, each of the second side wall portions 140 has, on its lower edge portion (base edge portion), each long side (the other pair of edges) of the bottom portion 120. On the other hand, it is connected so as to be able to rotate (continuously connected to bendable).
Each of the second side wall portions 140 can be displaced between the outwardly extending posture (FIG. 11) based on the standing posture (FIG. 9).

As shown in FIGS. 9 to 11, 13 </ b> A, and 13 </ b> B, each connecting member 190 has a right-angled isosceles triangle shape.
The length of two symmetrical sides of each connecting member 190 corresponds to the height of each first side wall 130 and each second side wall 140 (height in a vertical standing posture).

Each of the connecting members 190 is coupled to the side edge portion of each first side wall portion 130 so that the connecting member 190 can be rotated (connected in a foldable manner) on one of the two symmetrical sides.
Each connecting member 190 is rotatably coupled to each second side wall portion 140 at its hypotenuse (side facing the right apex).
The intersection of the other one side and the oblique side of the two symmetric sides of each connecting member 190 is the upper edge of each second side wall 140 (the upper edge in the standing posture of the second side wall 140). It is located at a position closer to the center by a length corresponding to the height of the second side wall 140 from the left and right edges (height in a vertical standing posture).
Thus, each first side wall part 130 and each second side wall part 140 are connected via each connecting material 190.

A hook and loop fastener (male) 143 (binding material) is attached in the vicinity of the left and right edges of the inner surface of the non-continuous second side wall 140A.
A hook-and-loop fastener (male) 153 (binding material) is attached in the vicinity of the left and right edges of the inner surface over the lid main body portion 151 and the continuous second side wall portion 140 of the lid portion 150.
Correspondingly, a hook-and-loop fastener (female) 193 (bonding material) is attached to each connecting member 190, and a hook-and-loop fastener (female) 133 is also attached to the connecting piece 132 of each first side wall 130. Yes.

This article storage case is manufactured as follows.
As shown in FIG. 12, first, a first connecting body 101 including a bottom portion 120, a pair of second side wall portions 140 and a lid portion 150, and a first side wall portion 130 including a pair of connecting members 190 in advance. The continuous bodies 102 (a pair) are formed integrally (continuously).
Then, after that, the first connecting body 101 and the pair of second connecting bodies 102 are combined to form the article storage case.
FIG. 10, which is an exploded perspective view, is an exploded view of the second connecting body 102 for the sake of convenience, paying attention to each element.

Next, the function and effect of this article storage case will be described.
An operation for changing the phase of the article storage case from the folded and unfolded state (FIG. 11) to the basic state (FIG. 9) will be described.
As shown in FIG. 11 → FIG. 13A → FIG. 13B, the worker displaces the pair of first side wall portions 130 in the folded posture toward the standing posture.
In that case, since each 1st side wall part 130 and each 2nd side wall part 140 are connected via the connection material 190, each 1st side wall part 130 is displaced toward a standing posture from a folding attitude | position. Accordingly, each second side wall portion 140 is also displaced from the outward extending posture toward the standing position.

That is, as the first side wall portion 130 tends to be displaced from the folded posture toward the standing posture, the connecting member 190 (to be precise, centering on a portion far from the hypotenuse, from the second side wall portion 140). Keep away.
Along with this, the second side wall portion 140 is displaced from the outward extending posture toward the standing posture so as to be pulled by the connecting member 190.

  Thus, as shown in FIG. 13B, each of the first side wall portions 130 and each of the second side wall portions 140 are positioned in a posture close to the standing posture, and the pair of first side wall portions 130 in a posture close to the standing posture. (The side edge portion) and each second side wall portion 140 (the side edge portion) in a posture close to the standing posture are close to each other.

Accordingly, on the side of the non-connected second side wall portion 140A, the surface fasteners (male) 143 of the non-continuous second side wall portion 140A and the surface fasteners (female) 193 of the connection materials 190 are opposed to each other. It will be close.
From this state, the surface fasteners (male) 143 and the surface fasteners (female) 193 of the connecting members 190 are combined.
Similarly, on the side of the continuous second side wall part 140B, the continuous second side wall part 140B and the hook-and-loop fastener (male) 153 of the lid main body part 151 (part of the continuous second side wall part 140B), The hook-and-loop fastener (female) 193 of each connecting member 190 approaches.
From this state, each surface fastener (male) 153 (part of the continuous second side wall portion 140B) and the surface fastener (female) 193 of each connecting member 190 are coupled.

  Thus, as shown in FIG. 9, the pair of first side wall portions 130 are both in the upright posture, the continuous second side wall portion 140B is also in the upright posture, and the pair of first side wall portions 130 in the upright posture (the continuous side walls 130B). The side edge part on the side of the provided second side wall part 140B) and the continuous second side wall part 140B (the side edge part) in the standing posture at least substantially coincide with each other.

  As described above, the article storage case changes phase from the folded and unfolded state (FIG. 11) to the basic state (FIG. 9).

  Further, by performing an operation reverse to the above, the article storage case changes from the basic state (FIG. 9) to the folded and unfolded state (FIG. 11).

As described above, this article storage case can also be easily phase-shifted from the folded and unfolded state (substantially flat state) to the basic state.
That is, as the first side wall part 130 is displaced from the folded position toward the standing position, the second side wall part 140 is also automatically displaced from the outwardly extending position toward the standing position. The side wall part 130 and the second side wall part 140 do not need to be operated and displaced toward the standing posture, respectively, and the phase can be easily changed from the folded and unfolded state (substantially planar state) to the basic state.

Conversely, the article storage case can also be easily phase-shifted from the basic state to the folded and unfolded state (substantially planar state).
That is, as the second side wall 140 is displaced from the standing posture toward the outwardly extending posture (outwardly leaning posture), the first side wall 130 is also automatically folded from the standing posture (inner side). Therefore, the first side wall 130 and the second side wall 140 do not have to be operated to be displaced toward the tilted posture, and can be easily folded and unfolded from the basic state. The phase can be changed to a state (substantially planar state).

When attempting to change the phase of the article storage case from the folded and unfolded state to the basic state, as shown in FIG. 13B, the pair of first side wall portions 130 and the non-continuous second side wall portion 140A are in the standing posture. By being positioned in a close posture, each surface fastener (male) 143 and each surface fastener (female) 193 are close to each other in an opposing state, and thus both can be easily combined.
Similarly, each of the pair of first side wall portions 130 and the continuous second side wall portion 140B is positioned in a posture close to a standing posture, whereby each surface fastener (male) 153 (the portion of the continuous second side wall portion 140B). And the respective surface fasteners (female) 193 are close to each other in the opposed state, so that they can be easily combined.
Thus, also in this article storage case, each first side wall 130 and each second side wall 140 can be easily maintained in the standing posture and easily maintained in the basic state.
In this respect as well, the article storage case can be easily phase-shifted from the folded and unfolded state (substantially flat state) to the basic state.

It should be noted that the above embodiment is merely one embodiment of the present invention, and it is needless to say that the present invention can be implemented with various modifications based on the knowledge of those skilled in the art.

For example, as a modification of the embodiment, the size of the inner sheet (60) may be smaller than that of the embodiment. That is, when the article storage case is in the basic state, the upper edge of the inner sheet (60) does not coincide with the upper edge of each first side wall (30) and each second side wall (40). Further, the first side wall part (30) and the second side wall part (40) may be positioned at midway height positions.
At that time, only the folded second side wall portion corresponding portion (88) and the vicinity thereof (the portion corresponding to the side edge portion of the first side wall portion) of the folded portion (80) of the inner sheet (60) are included. You may make it correspond with the upper edge part of a 1st side wall part (30) and a 2nd side wall part (40).

Moreover, about the surface fastener which couple | bonds each element in an Example, the male female may be reversed.
Moreover, things other than the hook-and-loop fasteners such as hooks (hooks) may be used as the elements for coupling the elements.
