SOLUTION: By the push piece 32 composed of the operation part 32a, the balance arm 32b and the pressurizing force input part 32c, the second engaging projections 26 of the cover body 16 are engaged with the first engaging projections 24 at three parts of the rotary frame 20 in a container main body 12. Then, at the time of opening the cover body 16, when the operation part 32a is pressurized, while the guide projections 32d is guided to the guide groove 12d, the balance arm 32b is slid and pushed in while being widened to a locking projection 34. Then, since the locking plate 36 of the rotary frame 20 is pressurized by the tip of the pressurizing force input part 32c, the rotary frame 20 is rotated and the second engaging projections 26 are detached from the first engaging projections 24, the cover body 16 can be manually rotated. In this case, the push-in operation of the push piece 32 can be performed with one hand.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an airtight cosmetic container for easily storing cosmetics.

[0002]

2. Description of the Related Art Generally, a cosmetic container, such as a compact container, is used for carrying cosmetics. The cosmetic container has a makeup plate formed on an inner frame provided in the container body, and the makeup plate is placed in the makeup plate. In addition to accommodating the food, a lid body is provided at the rear end portion of the container body so as to be openable and closable, and the lid body covers the upper side of the container body. The closed state of the lid body is maintained by the hook mechanism provided between the front end portions of the container body and the lid body, and the operation button for releasing the hook mechanism is projected from the front end portion of the container body. Has a general structure.

In this type of cosmetic container, in order to maintain the airtightness of the decorative dish, for example, Japanese Utility Model 6-25
As disclosed in Japanese Patent Publication No. 85, a packing material is provided on the back side of the lid, and when the lid is closed, the packing material is pressed against the upper surface of the peripheral portion of the decorative plate. However, in such a conventional hermetic cosmetic container, high accuracy is required for a hinged portion between the lid and the container body in order to maintain high hermeticity by the packing material.

[0004] Therefore, the applicant of the present invention has proposed a cosmetic container capable of sufficiently ensuring the airtightness of the interior of the makeup plate without being affected by the accuracy of the hinged portion of the lid. That is, in this cosmetic container, a makeup tray is housed in a rotating frame that is rotatably supported by the container body, and engaging protrusions that are engageable with each other are provided on the rotating frame and the lid body. The peripheral edge of the rotary frame is directly engaged with the lid body via the interposition. By directly locking the rotary frame and the lid in this manner, the packing material and the rotary frame or the upper edge portion of the decorative plate can be kept highly airtight regardless of the hinged portion of the lid. Further, the rotating frame is integrally provided with an operation button, and is provided with a biasing means for rotatingly biasing the engaging frame in the locking direction of the engaging projection. By operating the operating button, the rotating frame is biased by the biasing means. By rotating against the force, the engagement between the engagement protrusion of the rotary frame and the engagement protrusion of the lid can be disengaged.

[0005]

However, in such a conventional airtight cosmetic container, when the lid is opened, the rotary frame is rotated by the operation of the operation button to disengage the engaging projection. Since the button is provided integrally with the rotating frame, the operating button rotates in the rotating direction of the rotating frame during operation. However, operating the operation button in the direction of rotation of the rotating frame applies a lateral force to the cosmetic container, so in order to open the lid while holding the cosmetic container, the container body must be held with one hand. On the other hand, it is necessary to use both hands by operating the operation button in the lateral direction while the other hand is held, and there is a problem that the operability for opening the lid is not so good.

In view of the conventional problems, the present invention improves the operability when opening the lid while keeping the airtightness in the decorative plate high regardless of the accuracy of the hinged portion of the lid. The airtight cosmetic container is provided.

[0007]

In order to achieve the above object, the present invention provides a container body, a lid body which is openably and closably attached to the container body, and a cosmetic plate which is rotatably supported by the container body. The rotating frame and the lid, which are provided on the lid, and which are in pressure contact with the upper peripheral portion of the rotating frame or the decorative plate in the closed state of the lid, and the rotating frame and the lid, respectively, are provided to rotate the rotating frame. An engaging projection that is engaged or disengaged with the urging means, urging means that is provided between the rotating frame and the container body, and urges the rotating frame to rotate in one direction, and an opening formed in the container body. And a push piece that applies a rotational force in the opposite direction to the rotary frame, and by operating the push piece, the rotary frame is rotated in the opposite direction to release the engagement of the engaging projections. Airtight to allow opening of the lid In the cosmetic container, an operating portion formed in the central portion of the push piece and protruding outward from the opening of the container body, and a locking projection protruding from one end side of the operating portion and protruding from the container body. A balance arm having a leaf spring function that is locked so as to be movable relative to each other, and a pressing force input portion that projects from the other end of the operating portion and has a tip portion locked to the outer periphery of the rotary frame. , Transmitting the pressing force input to the operating portion as a rotational force to the rotary frame via the pressing force input portion, and forming a guide protrusion on one of the operating portion or the container body, and the guide protrusion on the other side. The guide groove is formed so as to be slidably engaged with the guide groove.

With the above structure, the airtight cosmetic container according to the present invention is rotated by the packing material as the rotary frame and the lid are directly engaged with each other by the engagement of the engaging projections provided on the rotary frame and the lid. Since the upper edge portion of the frame or the decorative plate can be brought into close contact with each other, the inside of the decorative plate can be sealed with the lid body closed regardless of the hinged portion of the lid body. Here, a push piece is used to rotate the rotary frame biased by the biasing means in the opposite direction to disengage the engaging means, and the push piece projects outward from the opening of the container body. By pushing the operating portion, the balance arm moves relative to the locking projection while the balance arm bends, and is pushed in by being guided by the guide projection and the guide groove, and at the other end of the operating portion. The pressing frame can be rotated by pressing the pressing force input unit. Therefore, since the rotation of the rotary frame is achieved by the pushing operation of the push piece, the operability is remarkably improved.
