Description

TECHNICAL FIELD The present invention relates to a storage container, and more particularly to a variable capacity storage container used for art material bags and the like.

2. Description of the Related Art Conventionally, there is a rectangular parallelepiped storage container whose upper portion has a lid that can be opened and closed.

FIG. 5 is a perspective view showing the appearance of a conventional storage container, where (1) shows an open state and (2) shows a closed state.

First, referring to FIG. 1(1), a storage container 71 has a rectangular parallelepiped container shape with a lid 73 connected to the upper edge of a back surface portion 72 so as to be foldable and open at the top. In this open state, the storage container 71 can be filled with items, and the contents can be used in the open state.

Also referring to FIG. 2B, the storage container 71 can be opened by rotating the lid 73 in the front direction (direction from the back surface portion 72 to the front surface portion 74) as indicated by an arrow 75. The tip edge 77 of the lid 73 of 71 overlaps the upper edge 78 of the front portion 74, and the open state shown in FIG. 1(1) can be shifted to the closed state shown in FIG. 1(2). If necessary, the front edge 77 of the lid 73 and the upper edge 78 of the front portion 74 are engaged by engaging means such as a magnet. In this closed state, the storage container 71 has a box-like shape with a storage space inside, and a handle or the like attached to the storage container 71 is used to carry stored items as necessary.

Further, as indicated by an arrow 76, by rotating the lid 73 in the rearward direction from the closed state, it is possible to shift to the open state.

In use, the storage container 71 is used by school children, for example, as an art material bag in an elementary school curriculum. First, in the open state, a water bucket (rectangular parallelepiped shape divided into a plurality of compartments with an open top) having a size approximately matching the capacity of the storage container 71 in the closed state is placed, and paints and brushes are placed inside the water bucket. store. Then, as described above, the lid 73 is rotated in the front direction and fixed in the closed state. The storage container 71 is carried to the sketching site in the closed state, and the above-described art materials stored therein are taken out and used.

However, in the conventional storage container 71 described above, the capacity does not change greatly between the open state and the closed state. Therefore, for example, when the storage container 71 is used as a painting material bag as described above, the paints and brushes stored in the water bucket in the closed state are removed from the storage container 71 because the water bucket is filled with water at the sketching site. There will be no space for internal storage. In such a case, the paints and brushes are spread outside the storage container 71 for use. It was possible to forget to put the paints and brushes that were spread out in the

Accordingly, there has been a long-awaited demand for a storage container that has a variable capacity and is easy to use, such as one that can be used while the painting materials are stored inside.

Incidentally, there is a conventional container 71 in which the side wall portion 80 itself opens by providing a fastener on the side wall portion 80 of the storage container 71. However, the storage container 71 with the side wall portion 80 opened is There was a risk that the stored items would leak out.

It is desirable that the storage container 71 has a variable capacity and improved usability even when it is used for purposes other than the art material bag.

It is a perspective view showing the appearance of a conventional storage container, (1) shows an open state, and (2) shows a closed state.

FIG. 1 is a perspective view showing the appearance of a storage container in an open state according to a first embodiment of the invention.

Referring to FIG. 1, storage container 1 is in a container-like open state having a rectangular parallelepiped shape with an open top, and a first portion 4 divided by a virtual plane 3 parallel to a side wall (front portion 2). and a second portion 5. Also, the first bottom surface portion 10 belonging to the first portion 4 and the second bottom surface portion 11 belonging to the second portion 5 are connected so as to be freely bendable. The first bottom surface portion 10 and the second bottom surface portion 11 are flush with each other in the open state.

That is, the imaginary plane 3 is the boundary between the first portion 4 and the second portion 5, and the ruled line 13 formed parallel to the front portion 2 on the bottom portion 9 of the container, and the ruled line 13 extends from the left side portion 7 and the right side portion. 8 and side ruled lines 14a and 14b formed so as to extend upward from the connecting points.

In other words, the container-shaped bottom portion 9 of the storage container 1 is divided into a first bottom portion 10 on the back side and a second bottom portion 11 on the front side via the foldable ruled line 13 . Further, side ruled lines 14a and 14b are formed on the left side portion 7 and the right side portion 8 so as to extend upward from a first vertex 21 at which the ruled line 13 is connected to each of the left side portion 7 and the right side portion 8. It is

In addition, in the first side wall portion 12a which is one of the opposed side walls belonging to the first portion 4 (the portion belonging to the first portion 4 of the container-shaped left side portion 7 and the right side portion 8), the side contacting the virtual plane 3 A right-angled triangular portion including (side ruled line 14a) and the side forming the upper edge 24 of the first side wall portion 12a is configured to be deformable as a gusset portion 25a made of a soft resin sheet. A gusset portion 25b is similarly formed in the first side wall portion 12b which is the other of the opposing side walls. The parts of the storage container 1 other than the gussets 25a and 25b are made of hard resin.

The gusset portion 25a is the first vertex 21 described above, the second vertex 22 connecting the side ruled line 14a and the upper edge of the left side portion 7, and the connecting portion between the upper edge of the left side portion 7 and the back portion 6. It is in the form of a triangular sheet connecting with a certain third vertex 23 . The gusseted portion 25b paired with the gusseted portion 25a has the same configuration on the right side surface portion 8. As shown in FIG.

In other words, the pair of container-shaped opposing side portions (the left side portion 7 and the right side portion 8) are provided with a pair of gore portions 25a and 25b, each of which constitutes a part of each of the pair of side portions 7 and 8. .

Further, in this embodiment, the length of the side (side ruled line 14a) in contact with the virtual plane 3 and the length of the side forming the upper edge 24 of the first side wall portion 12a are set to be the same. Therefore, the gusset portion 25a is formed in the shape of an isosceles right triangle. Furthermore, the flap 30a, which is a portion of the first side wall portion 12a other than the gore portion 25a, is also formed in a right-angled isosceles triangle congruent with the gore portion 25a. Therefore, the first side wall portion 12a is configured in a square shape. Further, the second side wall portion 15a, which is each of the opposing side walls belonging to the second portion 5, is formed in a square shape congruent with the first side wall portion 12a. The same applies to the gusset portion 25b, the flap 30b, the first side wall portion 12b, and the second side wall portion 15b facing these. The effects of the above configuration will be described later.

Since such a storage container 1 is capable of folding the first portion 4 toward the second portion 5 as indicated by an arrow 26, this will be described below.

FIG. 2 is a perspective view showing a first intermediate state in which the storage container shown in FIG. 1 is shifted from the open state to the closed state.

Referring to FIG. 1, storage container 1 is in a state immediately after starting to shift from the open state shown in FIG. 1 to a box-like closed state having a storage space therein as described later.

As described above, the ruled line 13 is bendable and the gusset portions 25a and 25b are deformable. is possible. The figure shows a state in which it is rotated about 10 degrees in the front direction.

Next, the gussets 25a, 25b can be folded outwardly or inwardly.

FIG. 3 is a 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 outward, and (1) shows a second intermediate state. and (2) is in the closed state.

First, referring to FIG. 1(1), the first bottom surface portion 10 (first portion 4) is further rotated in the front direction, and is in a state of being rotated about 30 degrees in the front direction.

As the transition to the closed state progresses, each of the edges 28a and 28b corresponding to the oblique side of the right-angled triangle of the gusset portions 25a and 25b and each of the side ruled lines 14a and 14b corresponding to the sides of the right-angled triangle contacting the above-described imaginary plane are formed. approach. As the two sides approach, the gussets 25a and 25b are deformed and folded outward in a mountain fold to form creases 29a and 29b corresponding to the center line of the right-angled triangle in the front-rear direction (front-rear direction). .

Next, referring also to FIG. 2(2), the above-described first bottom surface portion 10 rotates about 90 degrees in the front direction to complete the movement in the front direction, and the storage container 1 is in the box-like closed state. It is in a state of transition to

In the storage container 1 in the closed state, the first bottom surface portion 10 corresponds to the box-shaped rear surface portion, and the rear surface portion 6 corresponds to the lid of the box-shaped flat surface portion.

The box-shaped left side includes a second side wall 15a, a flap 30a that covers a portion of the second side wall 15a, and a gusset folded between the second side wall 15a and the flap 30a. 25a. The same applies to the box-shaped right side surface.

As described above, the gusset portion 25a is formed in the shape of a right-angled isosceles triangle. Any point on the edge 31 is reached when rotated 90°. Therefore, in the closed state of the storage container 1 as shown in FIG. portion) are parallel to the upper edge 31, and are aligned in the vertical direction. In this way, since the side 32, which is the connection point between the first side wall portion 12a and the rear portion 6, is aligned with the upper edge 31 of the left side portion 7, that is, the first bottom portion 10 faces the front portion 2 in the closed state. Since it becomes the part which carries out, it becomes a box of a rectangular parallelepiped shape, and the stability of the storage container 1 improves. The same applies to the gore portion 25b.

Furthermore, since the second side wall portions 15a and 15b, which are opposing side walls belonging to the second portion, have the same shape as the first side wall portions 12a and 12b, the tip edge 33 of the back portion 6 in the open state is closed. aligns with the upper edge 34 of the front part 2 at . Therefore, the stability of the storage container 1 is further improved.

Furthermore, as described above, since the flap 30a and the gusset 25a are in the same right-angled isosceles triangle shape, even if the gusset 25a is folded outward as it shifts to the closed state, the gusset remains in the closed state. The portion 25a is completely housed behind the flap 30a (the gap between the flap 30a and the second side wall portion 15a) to prevent the gore portion 25a from being seen from the outside. Such an effect is exhibited even when the flap 30a is larger than the gusset portion 25a. The same applies to the gore portion 25b.

In this manner, the storage container 1 has a rectangular parallelepiped container-like open state (see FIG. 1) and a box-like closed state having a storage space inside (see FIG. 3 (2)). and can be freely switched by folding back the first portion toward the second portion side, and the capacity can be made variable, thereby improving usability.

In the closed state, the front edge 33 of the back portion 6 and the upper edge 34 of the front portion 2 are aligned, and the front portion 2 and the back portion 6 serving as a lid covering the upper side are connected by a magnet and an adhesive tape. , a hook-and-loop fastener, a notch and a claw, a male screw and a female screw, or the like, and by providing engaging means and engaged means, the closed state can be fixed.

Next, FIG. 4 is a perspective view showing a transition from the open state to the closed state when the gusset portion of the storage container shown in FIG. 1 is folded inward, and (1) shows the second intermediate state. (2) is in the closed state.

Since the state shown in FIG. 3 is basically the same as that shown in FIG. 3 except that the gusset portion is folded inward as it shifts to the closed state, differences will be mainly described below.

Referring to FIG. 1(1), the gusset portions 25a and 25b are deformed as they shift to the closed state, and are folded inward in a valley fold to form the center line of the right-angled triangle in the front-rear direction (front-rear direction). There are formed creases 39a and 39b corresponding to the .

Also referring to FIG. 2(2), the flap 30a is accommodated on the back side (inward direction) of the second side wall portion 15a. Therefore, even if the gusset portion 25a is larger than the flap 30a, the gusset portion 25a is stored inside the storage container 1, thereby preventing the gusset portion 25a from being visually recognized from the outside. The same applies to the gore portion 25b.

The storage container 1 as described above can be used, for example, as a drawing material bag in the same manner as a conventional storage container. In the closed state, painting materials such as a water bucket, a palette, paints and brushes can be stored inside the box-like storage container 1 and carried. In addition, when in use, the container is opened to increase the capacity, and a water bucket filled with water and other drawing materials can be used side by side in the interior of the container-like storage container whose top is open. Therefore, the possibility that the user forgets to put the painting materials in when the user finishes using the painting materials and puts them away is reduced, and usability is further improved.

Further, in the open state (see FIG. 1), the first bottom surface portion 10 and the second bottom surface portion 11 of the storage container 1 are flush with each other (on the same plane), so that the capacity per installation area increases. and the usability is further improved.

In the above embodiment, the imaginary plane is parallel to the front portion, but it may be parallel to any side wall. In that case, the positional relationship of the front portion, back portion, left side portion, and right side portion, which are the side walls, is only shifted in order and is substantially the same.

Further, in the above-described embodiment, the gusset portion constitutes a right-angled triangular portion that is part of the side surface portion (first side wall portion). It may constitute a wider area including a right-angled triangular portion. Also, instead of the right-angled triangular portion, the gusset portion has an arbitrary length that is included in the upper edge 31 of the side portion (left side portion 7) with the first vertex 21 as the vertex in the open state, referring to FIG. may be configured as a portion (one or more) having a line segment of .

Furthermore, in the above embodiment, the gusset portion constitutes a right-angled isosceles triangular portion, but it may have another shape. For example, the side in contact with the imaginary plane may be longer (or shorter) than the side forming the upper edge of the first side wall. It is also possible to completely cover the upper part in the closed state by, for example, providing a flap at the tip edge of the back part.

Furthermore, in the above-described embodiment, the gusset portion is made of a soft resin sheet, but it may be made of another material that is deformable to the extent that it can shift from the open state to the closed state. For example, it may be in the form of a rubber sheet, and in this case, folding includes expansion and contraction and elastic deformation of the gusset portion. Furthermore, the entire gusset portion does not necessarily have to be deformable, and at least the outer edge thereof and the position where it is folded along with the transition to the closed state (in the case of the above-described first embodiment, the three sides of the right triangle and the crease). If is bendable, it is included in the fact that the gusset is deformable.

In short, the gusset portion should be deformed and folded when the container-shaped first bottom portion is rotated about the ruled line in the open state in the front direction, so that the gusset portion can be shifted to the closed state. good.

Furthermore, in the above-described embodiment, the ruled lines are formed on the bottom surface and the first bottom surface and the second bottom surface are connected to each other in a bendable manner. It may be a conceptual one formed in stages, a perforated line, a hinge-like structure, or the like.

Furthermore, in the above embodiment, the first portion is folded back toward the second portion when the storage container is shifted from the open state to the closed state, but the second portion may be folded back toward the first portion. be.

Furthermore, in the above embodiment, the second side wall portion and the first side wall portion have a congruent shape, but they may not have a congruent shape. For example, the length of the second side wall in the front-rear direction may be longer than the length of the first side wall in the front-rear direction.

Furthermore, in the above embodiment, an example of using the storage container as a drawing material bag has been given, but it may be used for other purposes. For example, it can be suitably used as a makeup tool case, a fishing tackle case, a pencil case, and the like.

Furthermore, in the above-described embodiment, the flap, which is the portion other than the gusset portion of the first side wall portion, is also formed in a right-angled isosceles triangle congruent with the gusset portion, but may have another shape. Also, the first side wall may not be equally divided.

Furthermore, although the first side wall is square in the above embodiment, it may have another shape.

Furthermore, in the above-described embodiment, the back portion is configured as a lid that covers the top when closed. Such an extended portion may be used as a complementary portion as a lid covering the upper portion, or may be used as a means for fixing the closed state to engage with the front portion or the like.

Furthermore, as another embodiment of the present invention, a partition plate may be provided at the boundary (on the imaginary plane) between the first portion and the second portion of the storage container. By configuring in this way, the division between the first part and the second part can be firmly fixed. For example, when the bag is used as an art material bag, a water bucket is stored in the second part and used in an open state. It is possible to prevent the water bucket from falling over. In addition, such a partition plate may be provided with a pair of deformable triangular sheet-shaped partition plate gussets that widen upward at the connection points on both sides of the partition plate and the side ruled line. With this configuration, the partition plate can be tilted toward the rear side (or the front side) in the open state, the capacity of the second portion (and the first portion) can be varied, and usability is improved. improves.

Further, as still another embodiment of the present invention, a pair of deformable triangular sheet-shaped front gussets that flare upward may be provided at the connection points between the front and left and right side portions. By configuring in this way, the front portion can be tilted in the front direction in the open state, the capacity of the second portion can be further increased, and usability is further improved.

Furthermore, in the above-described embodiment, the first portion is folded back toward the second portion, so to speak, so-called single opening structure, but a double opening structure may be used. That is, in addition to the first portion in the back direction of the second portion, a third portion similar to the first portion may be further provided in the front direction. In this case, from the open state of the storage container, the first portion is folded back toward the second portion (front direction), and the third portion is folded back toward the second portion (back direction) to shift to the closed state. At this time, the rear portion of the first portion and the front portion of the third portion, which serve as a lid for covering the top in the closed state, may be configured so as to overlap each other. (ie, the capacity of the second portion) can be freely adjusted, further improving usability.
