Description

The present invention relates to a storage container, and more particularly to a storage container used for an art material bag or the like.

Conventionally, a storage container has been proposed in which the open state and the closed state can be switched and the capacity is variable.

7A and 7B are schematic perspective views showing the appearance of a conventional storage container, in which FIG. 7A is a view showing an open state and FIG. 72 is a view showing a closed state.

For example, in Patent Document 1, referring to (1) of FIG. 7, the first portion 84 and the second portion have a rectangular parallelepiped shape with an open upper portion and are divided by a virtual plane 83 parallel to the front portion 82. A storage container 81 composed of 85 is disclosed. The first bottom surface portion 90 belonging to the first portion 84 and the second bottom surface portion 91 belonging to the second portion 85 of the storage container 81 are foldably connected to each other. Further, in the first side wall portion 92a which is one of the opposite side walls belonging to the first portion 84, the side ruled line 94a which is a side in contact with the virtual plane 83 and the side which becomes the upper edge 97 of the first side wall portion 92a are formed. The gusset portion 98a, which is a portion of a right triangle including the gusset portion 98a, is configured to be deformable. The gusset portion 98b is similarly configured in the first side wall portion 92b which is the other side of each of the facing side walls.

Such a storage container 81 is opened as described above by folding back the first portion 84 toward the second portion 85 side (rotating the first bottom surface portion 90 about 90 ° in the front direction about the ruled line 93). From the state, it is possible to switch to a rectangular parallelepiped box shape as shown in (2) of FIG. In the closed state, the first bottom surface portion 90 corresponds to the box-shaped back surface portion, and the back surface portion 86 corresponds to the lid of the box-shaped flat surface portion.

Japanese Unexamined Patent Publication No. 2019-047947

In the storage container 91 of Patent Document 1 described above, in the open state, the first bottom surface portion 90 and the second bottom surface portion 91 are flush with each other, and both the first bottom surface portion 90 and the second bottom surface portion 91 are flush with each other. It is possible to store stored items (not shown). On the other hand, in the closed state, the storage capacity is smaller than that in the open state. In this way, the capacity can be increased or decreased between the open state and the closed state, and the open state and the closed state can be used properly according to the usage situation, which is convenient.

However, when the transition to the closed state is started with the stored items placed on the first bottom surface portion 90, the first bottom surface portion 90 is placed on the first bottom surface portion 90 as it is inclined upward with respect to the ruled line 93. After the stored items move to the second bottom surface portion 91 side and shift to the closed state, the stored items tend to be randomly stored inside the storage container 81. Therefore, it may be difficult to find the desired item from the stored items when the item is opened again and used.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a storage container that has a clear range for storing stored items and is easy to use.

In order to achieve the above object, the invention according to claim 1 can switch between a container-shaped open state in which the upper part is open and a horizontally placed square pillar-shaped box-shaped closed state having a storage space inside. A storage container consisting of a square or rectangular bottom surface, and a box-shaped front surface, right side surface, and left side surface portion rising from each of the box-shaped front side, right side surface side, and left side surface side at the periphery of the bottom surface portion. The container body, the back surface rotatably connected to the box-shaped back side at the peripheral edge of the bottom surface, the flat surface portion connected so as to form a box-shaped top surface on the upper edge of the back surface, and the back surface. A flap body consisting of a pair of flap side surfaces attached to each of the left and right side edges of the portion and each of the left and right side edges of the flat surface portion, and each of the back side edges of the right side surface portion and the left side surface portion of the container body and the flap body. It has a pair of deformable gussets that can be attached to each of the left and right ends, and in the open state, the back surface of the flap body tilts diagonally upward toward the rear with the connection with the bottom surface of the container body as the axis. It is held in the state of being closed.

With this configuration, the back surface is slanted in the open state.

In the invention according to claim 2, in the configuration of the invention according to claim 1, each of the pair of gusset portions is attached to all the edges of the right side surface portion and the left side surface portion of the container body, and the pair of flap side surfaces. Inside each of the portions, it is attached to each of the connecting portion between the back surface portion of the flap body and the pair of flap side surface portions and the connecting portion between the flat surface portion and the pair of flap side surface portions.

With this configuration, the gusset portion and the flap side surface portion are in an independent state.

According to a third aspect of the present invention, in the configuration of the invention according to the first or second aspect, in the open state, a pair of flap side surface portions are attached to all the left and right side edges of the flat surface portion, and a pair of flap side portions are attached to each of the left and right side edges. Each upper edge side of the gusset portion passes on an extension line of each upper edge side of the right side surface portion and the left side surface portion of the container body.

With this configuration, the upper end of the flap side surface protrudes from the upper edge of the gusset.

The invention according to claim 4 is the length of the side where the length of the upper edge of each of the right side surface portion and the left side surface portion is the lower edge in the configuration of the invention according to any one of claims 1 to 3. It is set shorter than that.

With this configuration, the upper base of the right side surface portion and the left side surface portion has a trapezoidal shape shorter than the lower base.

The invention according to claim 5 has a center of gravity placed on the container body side in the open state in the configuration of the invention according to any one of claims 1 to 4.

With this configuration, when the storage container is grounded in the open state, it stands on its own with only the container body side grounded even when the stored items are not stored.

As described above, in the invention according to claim 1, since the back surface portion is slanted in the open state, the bottom surface portion serving as the storage portion becomes clear.

In the invention according to claim 2, in addition to the effect of the invention according to claim 1, the gusset portion and the flap side surface portion are in an independent state, so that the flap side surface portion is on the right side surface portion and the left side surface portion when closed. It is easier to get out of each and it fits better.

In the invention according to claim 3, in addition to the effect of the invention according to claim 1 or 2, the upper end of the flap side surface portion protrudes from the upper edge of the gusset portion, so that the flap is flapped when the gusset portion is folded. It is easy to be covered by the side surface, and it fits well when it is closed.

The invention according to claim 4 is closed because, in addition to the effect of the invention according to any one of claims 1 to 3, the upper bottom of the right side surface portion and the left side surface portion has a trapezoidal shape shorter than the lower bottom. When shifting to the state, it is possible to prevent the pair of flap side surface portions from being caught by the upper corner portions on the back surface side of each of the right side surface portion and the left side surface portion and being guided to the inside of the container body, which improves usability.

The invention according to claim 5, in addition to the effect of the invention according to any one of claims 1 to 4, when the storage container is grounded in the open state, the container body side even when the stored items are not stored. Since it stands on its own when only the ground is grounded, the state in which the storage container is placed is stable.

With reference to these figures, the storage container 1 can be switched between a container-shaped open state in which the upper part is open and a rectangular parallelepiped-shaped box-shaped closed state having a storage space inside and extending in the horizontal direction in the direction of the arrow. It is mainly composed of a container body 3, a flap body 4, and a pair of gusset portions 5a and 5b.

Specifically, the container body 3 is made of a combination of a resin sheet or the like whose interlining is covered with a cloth, and has a rectangular bottom surface 13 and a peripheral edge of the bottom surface 13 when the storage container 1 is box-shaped. It is composed of a front portion 10, a right surface portion 14 and a left surface portion 15 rising from each of the front side 20, the right side 24, and the left side 25. The front surface portion 10 is formed in the same shape as the bottom surface portion 13.

Further, the flap body 4 is formed by combining a resin sheet or the like whose interlining is covered with a cloth, and is rotatably connected to the back surface side 21 of the peripheral edge of the bottom surface portion 13 when the storage container 1 is shaped like a box. A flat surface portion 12 connected to the back surface portion 11 and the upper edge 31 of the back surface portion 11 so as to form a top surface when the storage container 1 is shaped like a box, and the left and right side edges 32a and 32b of the back surface portion 11. , And a pair of flap side surface portions 16a, 16b attached to each of the left and right side edges 33a, 33b of the flat surface portion 12. The back surface portion 11 and the flat surface portion 12 are formed in the same shape as the front surface portion 10 and the bottom surface portion 13 of the container body 3. Further, each of the flap side surface portions 16a and 16b is a sheet-like shape having a right-angled isosceles triangle shape. The left flap side surface portion 16a is attached to the entire edge of the left side edge 32a of the back surface portion 11 and the entire edge of the left side edge 33a of the flat surface portion 12. Further, the right flap side surface portion 16b is attached to the entire edge of the right edge 32b of the back surface portion 11 and the entire edge of the right edge 33b of the flat surface portion 12. The effect configured in this way will be described later.

Further, regarding the gusset portions 5a and 5b, the gusset portion 5a on the left side is made of a square cloth having no interlining, is deformable, and has a flap body, which is the entire edge of the back side edge 23 of the left side surface portion 15 of the container body 3. All edges of the connection portion 42a between the left side edge 32a of the back surface portion 11 of 4 and the flap side surface portion 16a, and a part of the connection portion 43a between the left side edge 33a of the flat surface portion 12 of the flap body 4 and the flap side surface portion 16a (described later). It is attached to each of the flap side surface portions 16a (a portion not including the upper end portion) inside the flap side surface portion 16a. Further, the side serving as the upper edge 47a of the left gusset portion 5a passes on an extension line of the side serving as the upper edge 27 of the left side surface portion 15 of the container body 3.

Further, the gusset portion 5b on the right side has the same configuration as the gusset portion 5a on the left side.

The effect configured in this way will be described later.

FIG. 3 is a schematic left side view of the storage container in the open state shown in FIG.

With reference to FIGS. 1 and 3, the bottom surface 13 of the container body 3 of the storage container 1 and the back surface 11 of the flap 4 are centered on the connecting portion 41 (the back surface 21 of the peripheral edge of the bottom surface 13). , Are rotatably connected. In the open state of the storage container 1, the back surface portion 11 of the flap body 4 is held in a state of being inclined obliquely upward.

In other words, when viewed from above (from the direction of the arrow in FIG. 3), the flat surface portion 12 borders a part of the inside of the back surface portion 11 (the virtual line 49 extending in the vertical direction of the side serving as the front edge 39 of the flat surface portion). It will cover the back side part).

As described above, since the back surface portion 11 is slanted in the open state, the bottom surface portion 13 becomes clear as a storage portion for storing stored items (not shown).

Further, the upward inclination angle θ is set to about 20 ° with respect to the virtual plane 7 flush with the bottom surface portion 13. With this setting, the upper part is widely opened in the open state, so that it is easy to store the stored items. Further, the back surface portion 11 can be used as a temporary storage place for stored items.

Further, the length of the side that becomes the upper edge 26 of the right side surface portion 14 is set shorter than the length of the side that becomes the lower edge 28 of the right side surface portion 14, and the length of the side that becomes the upper edge 27 of the left side surface portion 15 is set. It is set shorter than the length of the side that becomes the lower edge 29 of the left side surface portion 15. Then, as shown in FIG. 1, each of the right side surface portion 14 and the left side surface portion 15 has a trapezoidal shape in which the length of the upper base is shorter than the length of the lower base. The effect configured in this way will be described later.

FIG. 4 is a schematic perspective view showing a transition from an open state to a closed state when the gusset portion of the storage container shown in FIG. 1 is folded inward, and FIG. 4 (1) is a transition from an open state to a closed state. It is a schematic perspective view which shows the 1st intermediate state, (2) shows the 2nd intermediate state, and (3) shows the 3rd intermediate state.

In addition to FIGS. 1 and 2, referring to (1) of FIG. 4, the storage container 1 is in a state immediately after starting to shift from the open state shown in FIG. 1 to the closed state shown in FIG. is there. As described above, the back surface portion 11 of the flap body 4 is rotatably connected to the bottom surface portion 13 of the container body 3, and the gusset portions 5a and 5b are deformable. It is possible to rotate the connecting portion 41 with the bottom surface portion 13 in the front direction about the axis.

Next, the gusset portions 5a and 5b can be folded to either the outer side or the inner side, but first, the case where the gusset portions 5a and 5b are folded inward will be described below.

With reference to (2) of FIG. 4, the flap body 4 is further rotated in the front direction, and is in a state of being rotated in the front direction by about one-third from the open state. In this state, the gusset portions 5a and 5b are deformed and folded inward in a valley fold, respectively, and folds 45a and 45b corresponding to the center line in the front-rear direction (front-back direction) of the quadrangle are formed.

Further, referring to (3) of FIG. 4, the flap body 4 is further rotated in the front direction, and is in a state of being rotated in the front direction by about two-thirds from the open state. In this state, each of the flap side surface portions 16a and 16b covers a part of the outside of each of the right side surface portion 14 and the left side surface portion 15 of the container body 3. Further, each of the gusset portions 5a and 5b is further folded into a valley fold along each of the folds 45a and 45b so that the gusset portions 5a and 5b can be accommodated inside the left side surface portion 15 and the right side surface portion 14.

Further, as the flap body 4 rotates in the front direction, the front edge 39 of the flat surface portion 12 and the upper edge 30 of the front surface portion 10 are aligned as shown in FIG. 2, and the flap body 4 shifts to the closed state. Is completed.

Next, FIG. 5 is a schematic perspective view showing how the gusset portion of the storage container shown in FIG. 1 shifts from the open state to the closed state when the gusset portion is folded outward, and FIG. 5 (1) is a schematic perspective view showing the transition from the open state to the closed state. It is a schematic perspective view which shows the 1st intermediate state which shifts to a state, (2) shows the 2nd intermediate state, and (3) shows the 3rd intermediate state.

Note that FIG. 5 is basically the same as the state shown in FIG. 4 except that the gusset portions 5a and 5b are folded outward as the gusset portions 5a and 5b move to the closed state. I will explain mainly.

First, FIG. 5 (1) is a diagram showing a state similar to that of FIG. 4 (1), and description thereof will be omitted here.

With reference to (2) of FIG. 5, the flap body 4 is in a state in which the flap body 4 is rotated in the front direction from the state of (1) in FIG. 5 and is rotated in the front direction by about one-third from the open state. .. In this state, the gusset portions 5a and 5b are deformed and folded outward in a mountain fold, respectively, to form folds 45a and 45b corresponding to the center line in the front-rear direction (front-back direction) of the quadrangle.

Further, referring to (3) of FIG. 5, the flap body 4 is further rotated in the front direction, and is in a state of being rotated in the front direction by about two-thirds from the open state. In this state, each of the flap side surface portions 16a and 16b protrudes to the outside of each of the right side surface portion 14 and the left side surface portion 15. At this time, each of the gusset portions 5a and 5b is further folded into a mountain fold along each of the folds 45a and 45b, and the inside of the flap side surface portion 16a and the outside of the left side surface portion 15 and the inside and the right side surface portion of the flap side surface portion 16b. It will be sandwiched between the outside of 14.

Further, as the flap body 4 rotates in the front direction, the front edge 39 of the flat surface portion 12 and the upper edge 30 of the front surface portion 10 are aligned as shown in FIG. 2, and the flap body 4 shifts to the closed state. Is completed.

As described above, the gusset portions 5a and 5b are connected to the left and right side edges 32a and 32b of the back surface portion 11 and the flap side surface portions 16a and 16b, respectively, and the left and right side edges 33a of the flat surface portion 12. It is attached to the connecting portions 43a and 43b of each of the 33b and each of the flap side surface portions 16a and 16b. In other words, since the gusset portions 5a and 5b and the flap side surface portions 16a and 16b are in an independent state, the flap side surface portions 16a and 16b are gusseted portions 5a and 5b at the time of transition from the open state to the closed state. It is easy to go out to the outside of the right side surface portion 14 and the left side surface portion 15 without being influenced by the movement of being folded, and the closed state is better settled.

Further, since the upper end portions 36a and 36b of the flap side surface portions 16a and 16b protrude from the upper edges 47a and 47b of the gusset portions 5a and 5b, the flap side surface portions 16a and 16b are formed when the gusset portions 5a and 5b are folded. It is easier to cover and fits better when closed.

Further, the right side surface portion 14 and the left side surface portion 15 have a trapezoidal shape in which the length of the upper base is shorter than the length of the lower base. That is, as shown in (1) of FIGS. 3 and 4 and (1) of FIG. 5, each of the rear side upper corner portions 48a and 48b of the right side surface portion 14 and the left side surface portion 15 has an obtuse angle. Therefore, when shifting to the closed state, the inclined portions 37a and 37b of the flap side surface portion are delayed from hitting each of the back side upper corner portions 48a and 48b of the right side surface portion 14 and the left side surface portion 15 as compared with the right-angled one. be able to. Therefore, it is possible to prevent the flap side surface portions 16a and 16b from being caught by the back side upper corner portions 48a and 48b of the right side surface portion 14 and the left side surface portion 15 and being guided to the inside of the right side surface portion 14 and the left side surface portion 15 in the closed state. It fits better and is easier to use.

In the open state shown in FIG. 1 or 3, the container body 3 is formed of a material that is thicker and heavier than the flap body 4, and the storage container 1 is configured so that the center of gravity is placed on the container body 3 side. You can also do it.

With such a configuration, when the storage container 1 is grounded in the open state, even if the stored items are not stored, only the container body 3 side is self-supporting in a grounded state, so that the state in which the storage container 1 is placed is stable. .. Further, even when the stored items are temporarily placed on the back surface portion 11, if the center of gravity is placed on the container body 3 side, the inclination toward the back surface portion 11 side can be reduced, and the installation state becomes easy to stabilize.

Further, in the closed state shown in FIG. 2, a covering portion (not shown) having a fastening hole is further provided on the front edge 39 of the flat surface portion 12 so as to be rotatable, and a fastener provided on the front portion 10 (FIG. The closed state can be fixed by engaging with (not shown). In addition, the closed state can be fixed by providing engaging means and engaged means such as a magnet, an adhesive tape, a hook-and-loop fastener, a notch and a claw, and a male screw and a female screw.

FIG. 6 is a schematic perspective view showing the appearance of the storage container in the open state according to the second embodiment of the present invention, and is a view corresponding to FIG. 1.

Since the configuration of the storage container 51 according to this embodiment is basically the same as that of the first embodiment, the description here will not be repeated, and the differences will be mainly described.

With reference to FIG. 6, the gusset portions 55a and 55b of the storage container 51 in this embodiment are different from those in the first embodiment, and are triangular sheet bodies, and the gusset portion 55a on the left side is a container. It is attached to the entire edge of the back side edge 73 of the left side surface portion 65 of the main body 53 and a part of the inclined portion 77a of the flap side surface portion 66a of the flap body 54.

Further, the gusset portion 55b on the right side has the same configuration as the gusset portion 55a on the left side.

Similar to the first embodiment, the storage container 51 of this embodiment has the back surface portion 11 of the flap body 54 rearward with respect to the connection portion 71 with the bottom surface portion 63 of the container body 53 in the open state. It is held in a state of being inclined diagonally upward. Then, since the back surface portion 61 is slanted in the open state, the bottom surface portion 63 becomes clear as a storage portion for storing a stored object (not shown).

In the storage container 51 of this embodiment, since the gusset portions 55a and 55b are connected to the inclined portions 77a and 77b of the flap side surface portions 66a and 66b, the flap side surface portions 66a are compared with those of the first embodiment. , 66b can easily follow the movements of the gussets 55a and 55b. Therefore, the flap side surface portions 66a and 66b can be accommodated on both the outside and the inside of the left side surface portion 65 and the right side surface portion 64, respectively. For example, when the gusset portions 55a and 55b are folded inward, the flap side surface portions 66a and 66b are easily pulled inward and fit inside the left side surface portion 65 and the right side surface portion 64. Further, when the gusset portions 55a and 55b are folded outward, the flap side surface portions 66a and 66b are easily pulled outward and are accommodated on the left side surface portion 65 and the right side surface portion 64 outside. In any case, since the upper end portions 76a and 76b of the flap side surface portions 66a and 66b protrude from the upper edges 78a and 78b of the gusset portions 55a and 55b, the flaps are flapped when the gusset portions 55a and 55b are folded. It is easy to be covered with the side surface portions 66a and 66b, and the fit is improved when the side surface portions 66a and 66b are closed.

The storage container 1 or the storage container 51 in each of the above-described embodiments can be used as an art material bag in the same manner as the conventional storage container, for example. In the closed state, painting materials such as water buckets, palettes, paints and brushes can be stored and carried inside the box-shaped storage container 1 or the storage container 51. Further, in the open state at the time of use, a water bucket containing water is stored in the bottom surface 13 or the bottom surface 63 of the container-shaped storage container whose upper part is open, and other painting materials are temporarily placed in the back surface 11 or the back surface 61. Can be placed and used. Then, when the user finishes using the painting material and puts it away, the portion (bottom portion 13 or bottom portion 63) for storing the water bucket or the like and the painting material is clear, so that the bottom portion 13 or the bottom portion 63 has all the parts. Since the storage container 1 or the storage container 51 can be closed after the art materials are stored, the storage state is not cluttered and the usability is further improved.

In each of the above embodiments, the closed box shape is a rectangular parallelepiped shape extending in the horizontal direction, but the present invention is not limited to this. For example, a box-shaped quadrangular prism having a trapezoidal shape on the right side and the left side is also included. In short, it may be a square pillar shape that is placed horizontally. Further, the quadrangular prism may be composed of not only straight lines but also curved sides. Further, in addition to those having right-angled corners, those having a rounded shape are also included.

Further, in each of the above-described embodiments, the bottom surface portion has a rectangular shape, but the case where the bottom surface portion has a square shape is also applied.

Further, in each of the above-described embodiments, the front surface portion, the back surface portion, the flat surface portion, and the bottom surface portion all have the same shape, but the present invention is not limited to this. If the lengths in the width direction (right side-left side direction) are equal in the box shape, even if the lengths in the height direction (plane side-bottom side) or the depth direction (front side-back side) are different. good.

Further, although not described above, in each of the above embodiments, the connection portion between the bottom surface portion of the container body of the storage container and the back surface portion of the flap body is formed of two sheets corresponding to the bottom surface portion and the back surface portion. The front and back of the interlining are integrally covered with one piece of cloth and connected, and the cloth between the interlining on the bottom and the interlining on the back is folded so that it can rotate. is there. However, it is not limited to this. As long as it can be rotated at the connecting portion, it may be connected by a hinge, a string, or the like. Alternatively, one sheet may be rotatably provided with perforations, ruled lines, or the like.

Further, in each of the above embodiments, the container body and the flap body are formed of a sheet-like interlining made of resin or the like covered with a cloth, but the present invention is not limited to this. As long as the shape of the container body and the flap body can be maintained, it may be made of another material such as a hard resin sheet, wood, or metal.
