A hinge part 6 formed by a V-shaped groove is provided between the edge and the upper edge of the recessed part 10 of the lid part 4, respectively.
A side plate portion 3 having a thickness and length corresponding to the recessed portions 9 and 10 is connected to the lid portion 4 via the recessed portions 9 and 10.
The side plate portion 3, which is bent and stands up when the container is attached to the container, is configured to fit into the recessed portions 9 and 10, thereby improving the integrity of the entire container when the lid is attached.
In addition to having a protruding edge corresponding to the circumferential side of the container 1 on its peripheral edge as shown in the figure, the cover 4 may have other shapes such as a simple plate shape, but in any case, it can be folded. It is formed so that it rests on the upper edge of the container 1 when it is bent almost at right angles to the side plate part 3 which is bent and stands up, and the height of the side plate part 3 which is bent and stands up is set accordingly. Ru. Further, as a locking structure of the locking piece 5 to the other side 1b opposite to the side 1a of the container 1, the locking piece 5 is formed in a narrow constriction shape on the side connected to the lid 4. It has protrusions 11, 11 formed by the constriction on both sides of the free end edge thereof, and a narrow dovetail groove-shaped notch is formed on the upper side of the outer surface of the side portion 1b of the container body 1 corresponding to the constriction shape of the locking piece 5. Projecting steps 13, 13 are provided on both sides of the notch 12, and the locking piece 5 is attached to the container 1.
When the lid part 4 attached to the upper edge is bent and suspended, the locking part piece 5 fits into the notch part 12 on the outer surface of the side part 1b, and the protruding parts 11 at both ends become protruding step parts. It is configured to be locked to the lower surfaces of 13, 13.

The synthetic resin materials that are the constituent materials of the container of the present invention include styrene resin foams such as polystyrene resin and styrene-based copolymers, polyvinyl chloride resin foams, polyolefin resin foams, and other synthetic resin foams. The body is preferably formed integrally with the side plate part 3, lid part 4 and locking part 5 in a state in which they are unfolded relative to the container body 1, and at the same time hinge parts 6, 7, 8 formed by V-shaped grooves are formed. Note that the present invention can also be implemented in a container made of a non-foamed synthetic resin molded body.

The present invention is constructed as described above, and when used, when an article such as a glass bottle is stored in the container 1, a concave notch 9 is connected to the lower end of one side 1a of the container 1. The side plate part 3 is bent and raised by a hinge part 6 formed by a V-shaped groove, and is fitted into and attached to the recessed part 9 on the outer surface of the side part 1a, and the lid part 4 is attached to the side plate part 3 by a hinge part 7. It is bent and attached to the upper edge of the container 1, and at the same time the end of the side plate 3 on the side connected to the lid 4 and the side 4a of the lid 4 are bent.
