CONTAINER
A container can be easily manufactured because the container can be manufactured by die-forming a resin sheet. The container widens toward an outer circumferential side from side parts differing from a long side part on which a hinge part is formed, and is furnished with joining parts having mating surfaces that join with one another, and bent parts at outer circumferential edges of the joining parts, the bent parts being bent between container body parts in a direction in which the two separate from one another. Consequently, the container can maintain a freestanding form on an installation surface using the bent parts which spread so as to mutually separate, as legs. The above facilitates production and makes it possible for the container to stand in a stable state.
The container disclosed in Japanese Unexamined Patent Application Publication No. 2003-265401, for example, is known as a container for adhesive cleaning tools and the like. Containers such as these are formed by injection molding as a cover-type member that covers the adhesive portion of an adhesive cleaning tool. Injection molded containers can be easily molded in a highly durable form for freestanding storage.
One problem with the containers described above is that they are expensive to produce and that they are heavy because they are formed by injection molding. Consequently, there is a demand for stable, freestanding containers that can be easily manufactured.
SUMMARYA container according to an embodiment of the present invention is a container that is die-formed from a resin sheet. The container is provided with a container part that is constituted by superposing a multiplicity of side parts of a first container body part and a second container body part, which face one another; a hinge part that links together the first container body part and the second container body part at a first side part of the multiplicity of side parts; joining parts in the first container body part and the second container body part that widen to the outer circumferential side from at least a second side part differing from the first side part, and possess mating surfaces that join to one another; and bent parts at the outer circumferential edges of the joining parts, the bent parts being bent in a space between the first container body part and the second container body part in a direction in which the two separate from one another.
Such an embodiment facilitates production because it makes it possible to manufacture a container by die-forming a resin sheet. Additionally, a container widens to the outer circumferential side from a second side part differing from a first side part on which a hinge part is formed, and is provided with joining parts that possesses mating surfaces that join with one another, and bent parts at the outer circumferential edges of the joining parts that are bent in the space between the first container body part and the second container body part in a direction in which the two separate from one another. Consequently, the container can maintain a freestanding form on an installation surface using the bent parts which spread so as to mutually separate as legs. The above facilitates production and makes it possible for the container to stand alone in a stable state.
In one embodiment, bent parts are formed along the second side part and a third side part that is adjacent to the second side part in the circumferential direction, wherein the bent part formed along the second side part and the bent part formed along the third side part may be connected to one another in the circumferential direction.
In one embodiment, a protruding edge part is formed protruding in the outer circumferential direction on the leading edge of the bent parts.
In one embodiment, the dimension between the leading edge of the bent part on the first container body part and the leading edge of the bent part on the second container body part may be less than or equal to the thickness of the container part in the direction in which the first container body part and the second container body part face each other.
In one embodiment, the dimension between the leading edge of the bent part on the first container body part and the leading edge of the bent part on the second container body part may be greater than the thickness of the container part in the direction in which the first container body part and the second container body part face each other.
In one embodiment, the dimension between the leading edge of the bent part on the first container body part and the leading edge of the bent part on the second container body part may be 5% to 150% the thickness of the container part in the direction in which the first container body part and the second container body part face each other.
In one embodiment, an object to be contained in the container may be an adhesive cleaning tool.
In one embodiment, the inner surface of the first container body part and the inner surface of the second container body part may possess a convex part.
In one embodiment, the inner surface of the first container body part and the inner surface of the second container body part may be coated with a release agent.
The present invention facilitates the production of a container and makes it possible for the container to be freestanding in a stable state.

The container part 2 is configured by overlaying the multiplicity of side parts of a mutually opposing first container body part 10A and second container body part 10B. The container part 2 overall forms a roughly cylindrical shape. The container body parts 10A, 10B have a split shape formed by cutting the container part 2 in half on a specified reference plane (a virtual plane) located at a center line CL.

As shown in
Next, the dimensional relationships of the container 1 will be described with reference to
The dimension L1 between the leading edge of the bent part 6A and the leading edge of the bent part 6B may also be greater than the thickness L2 of the container part 2. In this case, stability can be improved when the container 1 is stood up with the side of the short side part 10c of the container 1 placed on an installation surface (the condition shown in
The relationship between the dimension L1 of the bent parts 6A, 6B on the side of the short side part 10d and the long side part 10b to the thickness L2 of the container part 2 is similar to that on the side of the short side part 10c. Further, in the present embodiment, depending on the structure relationship of the die, the dimension L1 of the bent parts 6A, 6B is set to an equal value at any of the side parts 10a through 10d. However, the dimension L1 of the bent parts 6A, 6B may also differ for each of the side parts 10a, 10d.
The dimension to which the joining parts 4A, 4B widen toward the outer circumferential side on the sides of each of the side parts 10a through 10d is not specifically limited, and can be optionally set within a range that the size is maintained in a moldable range and the container 1 does not tip over due to being too large. The dimension to which the protruding edge parts 7A, 7B widen toward the outer circumferential side on the sides of each of the side parts 10a through 10d is not specifically limited, and can be optionally set within a range that the size is maintained in a moldable range and the container 1 does not tip over due to being too large.
The action and effect of the container according to the present embodiment will be described next.
The container 1 according to the present embodiment facilitates production because makes it possible to manufacture a container 1 by die-forming a resin sheet. For example, production costs can be vastly reduced and the weight can be reduced compared with injection-molded containers.
Additionally, the container 1 widens toward the outer circumferential side from side parts 10b through 10d, which differ from the long side part 10a on which the hinge part 3 is formed, and is furnished with joining parts 4A, 4B that possesses mating surfaces 16 that join with one another, and bent parts 6A, 6B at the outer circumferential edges of the joining parts 4A, 4B, the bent parts 6A, 6B being bent in the space between the container body parts 10A, 10B in the direction in which the two separate from one another. Consequently, the container 1 can maintain a freestanding form on an installation surface, using the bent parts 6A, 6B, expanding so as to mutually separate, as legs. The above facilitates production and makes it possible for the container 1 to stand in a stable state.
For example, as shown in
In the container 1 according to the present embodiment, the bent parts 6A, 6B are formed along the various side parts 10b through 10d adjacent to one another in the circumferential direction, and the bent parts 6A, 6B that are formed along each of the side parts 10b through 10d are connected to one another in the circumferential direction. Consequently, when the bent parts 6A, 6B on any one of the side parts are functioning as legs, the bent parts 6A, 6B of the side parts that are adjacent to the side part function as reinforcing parts that strengthen the legs.
In the container 1 of the present invention, protruding edge parts 7A, 7B protruding toward the outer circumferential side are formed at the leading edge side of the bent parts 6A, 6B. Thus, the protruding edge parts 7A, 7B can function as contact points that abut the installation surface G.
The present invention is not limited by the embodiment described above.
For example, bent parts 6A, 6B are formed at least next to either of the short side part 10c and the long side part 10b in the embodiment described above, and bent parts 6A, 6B may be omitted from other side parts. For example, in the container 1 of the embodiment described above, the joining parts 4A, 4B, bent parts 6A, 6B, and protruding edge parts 7A, 7B may be omitted from the short side part 10c on the negative side in the Z-axis direction. The container 1 may stand on the short side part 10c with the bottom surface of the end wall part 12 of the container part 2 in contact with the installation surface G. Alternatively, the edge-most surface of the end wall part 12 may also be cut off. Note that in this case, the bent parts 6A, 6B on other side parts function as legs.
Additionally, bent parts 6A, 6B and protruding edge parts 7A, 7B do not need to extend over the entirety of all side parts, and may be formed on only some of the side parts. For example, the bent parts 6A, 6B and protruding edge parts 7A, 7B may be cut off at the corners between the various side parts so that they are not continuous with one another in the circumferential direction. Alternatively, bent parts 6A, 6B, and protruding edge parts 7A, 7B may be formed at only a region of an edge part side in each of the side parts. For example, joining parts 4A, 4B, bent parts 6A, 6B, and protruding edge parts 7A, 7B may be formed only at portions of both edges in the X-direction of the short side part 10c.
Also, an opening may be formed not only on the side of the short side part 10d, but also on the side of the short side part 10c. In a case where the handle 100b is pulled out on the side of the short side part 10c, the container 1 may also stand on the installation surface G with the bent parts 6A, 6B on the side of short side 10d used as legs.
Additionally, the hinge part does not need to be formed on the side of the long side part 10a, and may be formed on another side part. For example, as shown in
Also, a hinge part may also be formed on the side of the short side part in which the opening is formed for pulling out the handle of the contained object 100. For example, as shown in
Further, the hinge part may not necessarily have a structure in which it is matched between the first container body part and second container body part (namely, having two creases), as in the embodiment described above. For example, the first container body part and second container body part may be connected with a single crease, or the hinge part may further have a structure wherein there is one or more crease.
In the embodiment described above, protruding edge parts are formed and the leading edges of said protruding edge parts function as contact points that abut the installation surface. However, these protruding edge parts may also be omitted. In this case, the surfaces on the outer circumferential side of the bent parts become the contact points that abut the installation surface.
