Abstract

The present disclosure provides a container with an increased movable range of an upper wall with respect to a side wall. According to the present disclosure provided is a container including a side wall, an upper hinge member, and an upper wall, wherein the upper hinge member and the side wall are connected rotatably around a first rotation axis, the upper hinge member and the upper wall are connected rotatably around a second rotation axis, and the first and second rotation axes are parallel.

First claim

The invention claimed is:

1. A container comprising:
a side wall, an upper hinge member, and an upper wall,
wherein the side wall has a first concave portion,
the upper wall has a second concave portion,
the upper hinge member is located across the first concave portion and the second concave portion,
the upper hinge member has a case, a first projecting shaft, and a second projecting shaft, the upper hinge member and the side wall are connected rotatably around the first projecting shaft,
the upper hinge member and the upper wall are connected rotatably around the second projecting shaft, and
the first and second projecting shafts are parallel, wherein
when the container is in an upright orientation, such that the side wall is disposed parallel to an up-down axis, the container is configured such that the second projecting shaft is always arranged further in an up direction, along the up-down axis, than the projecting shaft,

wherein the case of the upper hinge member comprises a rotation restricting portion configured to restrict rotation of the upper hinge member,
the rotation restricting portion is configured to abut against a lower surface of the first concave portion, so that when the container is in an upright orientation, such that the side wall is disposed parallel to the up-down axis, the second projecting shaft is not arranged further in a down direction, along the up-down axis, than the first projecting shaft,
the case of the upper hinge member comprises a first arc surface having a center that is the first projecting shaft,
the first concave portion is provided with a second arc surface, and
the upper hinge member is configured to maintain contact between the first and second arc surfaces throughout an entire range of rotation of the upper hinge member with respect to the side wall of the container.

2. The container of claim 1 ,
wherein an angle of a plane passing through the first and second projecting shafts with respect to an outer surface of the side wall is 91 to 135 degrees.

3. The container of claim 1 ,
wherein the first projecting shaft is arranged in the first concave portion, which is provided on an outer surface side of the side wall, and
the first concave portion is configured not to penetrate the side wall.

4. The container of claim 1 , comprising second to fourth side walls, a second upper wall, and a bottom member,
wherein the side wall is regarded as a first side wall, while the upper wall is regarded as a first upper wall,
the first and second side walls face each other,
the third and fourth side walls face each other and are provided between the first and second side walls,
the first to fourth side walls are configured to be rotatable with respect to the bottom member, and
the second upper wall is configured to be rotatable with respect to the second side wall.
