[0015]

The invention described in claim 1 has the following effects.
In the closed state of the lid where the elastic restoring force of the elastic body has acted on the lid,
When the flexible top surface is pressed, the locking action of the locking mechanism is released by the bending deformation of the top surface, and at this time, the lid is fully opened by the elastic restoring force of the elastic body,
The top opening opens. In other words, the elastic body
It is arranged '', so not only the lid is closed but also the lid
Continue to apply the resilience to the lid even during the wide opening
The lid can be fully opened when the lock is released.
can do. For this reason, the lid can be immediately fully opened only by placing the container on the floor or on a desk and pressing the top surface of the container body with one hand, and with one hand, the contents of the container body can be opened from the opening of the top surface portion. Can be taken out.

The second aspect of the invention has the following effects. Since the hinge is an indirect joining hinge in which the container body and the lid are formed separately, no resistance is generated when the lid is opened and closed. For this reason, when the elastic restoring force of the elastic body fully opens the lid, the resistance from the hinge does not act, so that the elastic restoring force is not canceled and the lid can be opened easily and quickly.

The invention described in claim 3 has the following operations. The locking mechanism includes a first locking portion on the container body side and a second locking portion on the lid side.
Since the first locking portion is formed in a ring shape, bending deformation caused by pressing the top surface portion 18 of the container body is easily transmitted to the first locking portion. Thus, since the first locking portion is easily deformed, the locking action between the first locking portion and the second locking portion is easily released, and the lid can be easily opened.

The invention described in claim 4 has the following effects. One end of the elastic body is provided on one of the top surface or the lid of the container body, and the other end is configured to be able to contact the other of the lid or the top surface in the fully opened state of the lid. The elastic restoring force can be reliably applied to the fully opened position of the lid, and the lid can be stably positioned at the fully opened position at a predetermined angle.

The invention described in claim 5 has the following effects. On the top surface of the container body, the pressing designation portion is formed at a position where the bending deformation of the top surface portion is most easily transmitted to the locking mechanism portion. The container can be easily guided to the position of the surface portion, and the container does not fall down due to the pressing of the top surface portion, and its stability can be secured.

The invention described in claim 6 has the following effects. Since the second locking portion can be locked to the ring-shaped first locking portion only at one position opposite to the hinge, the amount of bending deformation due to the pressing of the top surface of the container body is small. However, the locking operation between the first locking portion and the second locking portion can be easily released, and the first locking portion at the time of closing the lid can be easily released.
At the time of locking between the locking portion and the second locking portion, it is possible to make the user sense a click feeling of locking.

The invention described in claim 7 has the following operations. Since the one end portion of the L-shaped elastic body in a side view is arranged so as to be fitted to the lid, the attachment of the elastic body becomes easy. In particular, in the case of the indirect joint hinge, the elastic body may be fitted to the lid with the lid detached from the container body, and then the lid may be hinged to the top surface of the container body. Can be more easily attached, and the assemblability of the container can be improved.

The invention according to claim 8 has the following effects. The other end of the elastic body whose one end is fitted to the lid is formed in a tapered shape at least at the end, and the other end is in a fully opened state of the lid and in a floating state in contact with the top surface of the container body. Therefore, all the elastic restoring force (elastic energy) of the elastic body can be used during the lid opening process, and the urging force acting on the lid from the elastic body can be increased. If the other end of the elastic body is in contact with the top surface of the container body when the lid is fully opened in the lid opening process, the elastic body remains deformed, and as a result, the elastic restoring force of the elastic body cannot be used at all, and the lid is not used. The urging force acting on the lid becomes weaker, and the opening speed of the lid decreases. As described above, since all the elastic restoring force of the elastic body can be used in the lid opening process, the lid can be quickly and smoothly opened to the fully opened position, and this opening operation can be performed well.

When the lid is fully opened, the other end of the elastic body whose one end is fitted to the lid is configured to be in a floating state with respect to the top surface of the container body, and when the lid is fully opened, an elastic restoring force is applied from the elastic body to the lid. Since it does not act, the elastic body does not bend and deform at the time of full opening, and it is possible to prevent one end of the elastic body from falling off the lid.
