Utility Model Registration No. 2600683

  In the above prior art, the combination of the inclined surfaces can release the engagement with the container body by securing the push-up amount of the claw piece and thus the lid body with a short operation stroke of the push piece. It has been desired to devise a structure that can secure the same amount of push-up.

  The present invention was devised in view of the above-described conventional problems, and it is possible to release the engagement with the container main body by sufficiently securing the push-up amount of the push body with an extremely short operation stroke of the push piece. An object is to provide a compact container.

  In the compact container according to the present invention, the container main body and the lid are hinged so as to be freely opened and closed at the respective rear portions, a recess is formed in the front end edge of the container main body, and a first surface is formed on the inner surface of the recess. An engagement protrusion is formed, a second engagement protrusion is formed on a claw piece that hangs down from the front edge of the lid, and the lid is engaged by the engagement of the first engagement protrusion and the second engagement protrusion. A push piece is disposed in the recess of the container body so as to be movable back and forth, and a protrusion is formed in the recess, and the push piece is formed from the rear surface of the pressing front wall. In a compact container that is extended rearward through a flexure and is integrally formed with an operating piece whose upper side is in contact with the claw piece and whose lower side is in contact with the protrusion, the upper side of the operating piece and the claw At least one of the pieces is a first inclined surface, and both the lower side of the working piece and the protrusion are set as one. And the flexible piece side end portion of the second inclined surface of the working piece is gradually made to the protrusion in response to the flexible deformation of the flexible part. It is characterized by a projecting angle portion that rises.

  In the compact container according to the present invention, when the lid is pushed up to release the engagement with the container main body, the push-up amount of the lid can be sufficiently secured with a very short operation stroke of the push piece.

  Hereinafter, a preferred embodiment of a compact container according to the present invention will be described in detail with reference to the accompanying drawings. As shown in FIGS. 1 to 3, the compact container according to the present embodiment basically includes a container body 1, a push piece 2, and a lid 3.

  The container body 1 is formed with a recess 4 for storing cosmetics on the upper surface. In addition, a recess 5 is formed at the front end edge of the container body 1, and a first engagement protrusion 6 is formed at the upper center of the back surface of the recess 5. Furthermore, a protrusion 7 is formed on the inner surface of the recess 5 so as to be positioned below the first engagement protrusion 6 and project forward. On the upper side of the protrusion 7, a protrusion-side second inclined surface 7 a that is inclined upward as it goes rearward is formed. Furthermore, a guide groove 9 extending in the front-rear direction is formed on the bottom surface of the recess 5. A push piece 2 is disposed in the recess 5 of the container body 1.

  The push piece 2 is formed in a substantially U-shaped plane cross section comprising a pressing front wall 2a having a height substantially equal to the height of the recess 5 of the container body 1, a bottom wall 2b extending rearward from this, and a pair of left and right side walls 2c. Is done. Further, a protrusion 10 is formed on the lower side of the bottom wall 2b, and the push piece 2 is slidable in the recess 5 in the front-rear direction by engaging the protrusion 10 with the guide groove 9 of the recess 5. It is arranged. In addition, on the rear surface of the pressing front wall 2a, there is integrally formed an operating piece 8 that extends rearward through a flexible portion 11 that is formed thin and flexible in a vertical direction.

  Further, the operating piece 8 is formed with a first inclined surface 8a which is inclined downward toward the rear side on the upper side, and is inclined upward toward the rear side toward the rear side. An operating piece side second inclined surface 8b that forms a pair with the two inclined surfaces 7a is formed. In particular, the flexible piece side end of the working piece side second inclined surface 8b gradually moves the working piece 8 with respect to the protruding side second inclined surface 7a in response to the flexible portion 11 being flexibly deformed upward. In order to stand up, it is formed as a downward projecting angle portion 8c.

  The lid 3 is formed so as to cover the upper surface of the container main body 1, and a mirror 12 is attached to the inner surface thereof, and is hinged so as to be freely opened and closed via hinges 13 at the container main body 1 and the respective rear portions. A claw piece 14 is suspended from the front center portion of the lid 3, and a second engagement protrusion 15 that can engage with the first engagement protrusion 6 of the container body 1 is formed on the lower inner surface of the claw piece 14. It is formed.

  In the compact container having the above-described configuration, when the lid 3 is closed, the first engagement protrusion 6 of the container body 1 and the second engagement protrusion 15 of the lid 3 are engaged and locked. It has become. The operating piece 8 of the push piece 2 is in contact with the upper first inclined surface 8a and the lower end portion of the claw piece 14 of the lid 3, and the operating piece side second inclined surface 8b is the projecting side second inclined surface 7a. The flexible portion 11 is in a substantially horizontal state in a state of surface contact. Further, the pressing front wall 2 a of the push piece 2 substantially coincides with the front surfaces of the container body 1 and the lid 3.

  In order to open the lid 3 of such a compact container from its locking position, the pressing front wall 2a of the push piece 2 is pressed inward. Then, the push piece 2 horizontally moves rearward in the bottom surface of the recess 5 of the container body 1, and accordingly, the operating piece 8 becomes a gap between the protrusion 7 of the container body 1 and the claw piece 14 of the lid 3. At this time, with respect to the operating piece side second inclined surface 8b, the sliding of the projecting portion side second inclined surface 7a starts almost simultaneously with the upward flexible deformation of the flexible portion 11. The protrusion 8c comes into contact with the protrusion-side second inclined surface 7a, whereby the operating piece 8 immediately moves on the protrusion-side second inclined surface 7a when the push piece 2 is pushed. Is swung upward in a form that gradually moves at an angle. Simultaneously with this swing-up operation, the first inclined surface 8a of the operating piece 8 slides with respect to the lower end portion of the claw piece 14 so as to push up the claw piece 14 upward, and the claw piece 14 jumps up upward. The action can be obtained by the upper and lower inclined surfaces 8a and 8b of the operating piece 8 and the projecting angle portion 8c. Thus, the engagement between the first engagement protrusion 6 and the second engagement protrusion 15 is released, and the lid body 3 can be opened.

  In particular, in the present embodiment, the operating piece side second inclined surface 8b and the projecting angle portion 8c simply move along the projecting side second inclined surface 7a, and do not simply have a wedge function. However, according to the flexible deformation of the flexible portion 11, the projecting angle portion 8c serving as the end of the operating piece side second inclined surface 8b changes the operating piece side second inclined surface 8b on the protruding portion side second inclined surface 7a. The angle is gradually moved so that even when the operation stroke of the push piece 2 is extremely short, a sufficient amount of pushing up of the claw piece 14 and thus the lid 3 can be secured instantaneously. The engagement with the container body 1 can be released. Since the operation stroke can be set to be short as described above, the size of the recess 5 can be reduced, and the external dimensions of the entire compact container can be reduced.
