  The present invention has been made in view of the above-described conventional problems, and even if the contents are soft, the contents can be protected by holding the lid closed to protect the contents and being folded compactly. It is an object of the present invention to provide a container that can be made and less bulky during nesting.

The present invention employs the following means in order to solve the above problems.
That is, the container of the present invention includes a bottom plate, a pair of first side plates and a pair of second side plates that are foldable with respect to the bottom plate via hinges, and a pair of first side plates that face each other. A foldable container provided with a pair of lid plates each provided on the end side and capable of opening and closing with respect to the first side plate, and a pair of first hinges connecting the first side plate and the lid plate, Each double hinge connects the first hinge part pivotally connected to the first side plate and the second hinge part pivotally connected to the cover plate, and can be engaged with the first side plate. In a state in which a pair of cover plates are closed and the pair of cover plates are closed, the first hinge portion and the second hinge portion of each double hinge extend in a state substantially parallel to the pair of cover plates, respectively. so as to be engaged with the first side plate, respectively, by the The stop member includes a substrate and a recessed block-shaped locking block connected to the substrate, and the double hinge is configured such that a part of the substrate and the locking block is locked to a corner of the first side plate. The first hinge portion and the second hinge portion are supported in a state substantially parallel to the lid plate .
According to the container of the present invention, when the lid is rotated in the closing direction by the double hinge from the state where the first and second side plates are erected, the pair of double hinges are substantially parallel to the lid, for example, the first Since the pair of lids abut each other to close the opening of the container so as to extend in a direction substantially perpendicular to the side plate and cover the lid, a locking member that rotates integrally with the double hinge at that time is a first side plate It is possible to support the double hinge and the lid body by engaging with. On the other hand, when the lid and the first side plate are folded at the first and second hinge parts and folded on the bottom plate during folding, the double hinge is, for example, substantially the same as the first side plate and the lid stacked on the bottom plate. Since it is bent and held so as to be orthogonal, the opening / closing width of the lid is smaller than the opening width of the container, and can be folded without interfering with each other.

  According to the container of the present invention, when the container is assembled, the double hinge extends so as to form a part of the lid together with the lid, so that the opening can be closed, and in the folded state, the double hinge bends to the lid. Thus, the pair of double hinges and the lid can be folded compactly without interfering with each other and can be prevented from becoming bulky when nesting in the folded state. In addition, the contents are not pressed or interfered with each other because the double hinge and the lid are supported by the locking member in a state where the double hinge and the cover are extended substantially in parallel in the container assembly state.

The locking member includes a substrate and a recessed block-shaped locking block connected to the substrate, and a part of the substrate and the locking block is locked to a corner portion of the first side plate, whereby the double hinge The one hinge part and the second hinge part may be supported in a state substantially parallel to the cover plate.
In a state where the container is assembled, the double hinge can be supported in a substantially parallel state together with the cover plate by the base plate of the locking member and the locking block.
In addition, the first side plate and the cover plate are folded by a double hinge, overlapped with each other and folded on the bottom plate, and the pair of double hinges face each other at positions that do not interfere with each other while being substantially orthogonal to the first side plate and the cover plate. It may be. Usually, a pair of lids need to be at least as long as the width of the bottom plate in order to close the opening of the container. However, in the present invention, in order to fold and fold the lid and the double hinge, the lids protrude outward from the bottom plate. It is possible to fold compactly while suppressing interference with each other.
A protrusion extending on the extension of the first side plate is provided on the upper portion of the first side plate, and a plurality of containers can be stacked by accommodating the bottom plate of another container between the raised portions of the first side plate. It may be possible to nest the container in an assembled state.
