  However, in the above-described compact container, the work of assembling the U-shaped spring material 44 into the through-hole 43 formed in the connecting portion 42a of the lid 42 is troublesome and the workability is poor. Moreover, since the spring member 44 is formed in a U shape and has a complicated structure, the manufacturing cost is increased, and the cost of the compact container is increased. In addition, since the through hole 43 is formed in the connecting portion 42a of the lid body 42, the structure of the mold for producing the lid body 42 becomes complicated and the manufacturing cost becomes expensive. Cost increases. Moreover, when the lid is opened, the feel of the lid 42 springing up due to the elastic force of the spring material 44 feels hard.

  The present invention has been made in view of such circumstances, and an object of the present invention is to provide a compact container in which the lid body smoothly jumps when the lid is opened, and is easy to assemble and inexpensive.

  In order to achieve this object, the compact container of the present invention comprises a container body, and a lid body whose rear end portion is hinged to the rear end portion of the container body so as to be rotatable. A recess is formed in at least one of the upper surface of the container and the lower surface of the lid, a rubber elastic member is fixed to the recess with the upper end protruding from the recess, and the upper surface of the container body is covered with the lid In this state, the upper end portion of the rubber elastic member is pressed against the other of the upper surface of the container body and the lower surface of the lid body.

  That is, in the compact container of the present invention, the rubber elastic member is fixed to the concave portion formed in at least one of the upper surface of the container main body and the lower surface of the lid body with the upper end portion protruding from the concave portion. Then, the upper end portion of the rubber elastic member is pressed against the other of the upper surface of the container body and the lower surface of the lid body in a state where the upper surface of the container body is covered with the lid body. As described above, in the compact container of the present invention, the upper end portion of the rubber elastic member is protruded from the recess formed in at least one of the upper surface of the container body and the lower surface of the lid body, and the upper end of the rubber elastic member is closed when the lid is closed. The part is pressed with the other of the upper surface of the container body and the lower surface of the lid, and is elastically deformed in a compressed state. As a result, when the engagement between the container body and the lid is released when the lid is opened, the rubber elastic member tries to return to the original posture by its own elastic force, and the lid is automatically formed at the upper end of the rubber elastic member. Can be flipped up and opened. Moreover, the rubber elastic member can be assembled to the container main body or the lid simply by fixing the rubber elastic member to the recess formed in at least one of the upper surface of the container main body and the lower surface of the lid, and the assembly work becomes easy. Workability is improved. In addition, since it is not necessary to form the rubber elastic member in a special shape such as a U-shape, the production cost of the rubber elastic member is reduced (that is, the price of the rubber elastic member is reduced), and accordingly the compact container. The cost is also low. In addition, since only the recess is formed in at least one of the upper surface of the container body and the lower surface of the lid body, the structure of the mold for producing the container body or lid body is simplified, and the container body or lid body is simplified. Since the production cost of the container is reduced, the cost of the compact container is further reduced. In addition, the lid can be opened with a soft and smooth feel as compared with a normal flip-up mechanism.

  Further, when the rubber elastic member is made of urethane rubber, it is excellent in durability, and the lid body can be flipped up in a stable state over a long period of time.

  Further, when an opening operation piece that can release the engagement between the container body and the lid is provided, the lid is automatically flipped up when the opening operation piece is operated to release the engagement. be able to.
