Description

  The present invention relates to an airtight container suitable for containing contents such as highly volatile cosmetics.

  Conventionally, various types of cosmetic containers and the like have been proposed as an airtight container such as a cosmetic container that contains cosmetics containing volatile components in order to maintain the internal airtightness. For example, there is an airtight cosmetic container shown in FIG. The hermetic cosmetic container includes a container main body 51 in which a cosmetic storage portion 51a is formed on an upper surface and an annular groove 51b is formed in a peripheral portion of the cosmetic storage portion 51a, and a lid 52 that opens and closes the container main body 51. And a ring-shaped packing 53 attached to the annular groove 51b of the container body 51, and the cylindrical rib 52a protrudes integrally from the back surface of the lid 52 along the outer shape of the ring-shaped packing 53. In the state where the container body 51 is closed with the lid 52 closed, the bulging portion 53a of the ring-shaped packing 53 is pressed against the inner periphery of the cylindrical rib 52a to seal the inside of the cosmetic storage portion 51a. (For example, refer to Patent Document 1).

However, in the above airtight cosmetic container, since the ring-shaped packing 53 is attached to the annular groove 51b formed in the peripheral edge of the cosmetic container 51a of the container main body 51, the ring-shaped packing 53 is enlarged and expensive. become. Thus, for example, as shown in FIG. 32, a compact container has been proposed in which an annular gasket 57 is provided on the lid 56 so that the diameter of the annular gasket 57 can be reduced. The compact container includes a container body 55 in which a dish part 55 a is formed at the center of the upper surface and the dish part 55 a is filled with a cosmetic 58, a lid body 56 that covers the upper surface of the container body 55, and the lid body 56. An annular gasket 57 disposed on the top surface is provided, and the annular gasket 57 is held in an internally fitted shape by a concave plate 59 bonded and fixed to the top surface of the lid body 56 (for example, Patent Document 2).

  However, in the above compact container, since the annular gasket 57 disposed on the top surface of the lid body 56 is held by the concave plate 59 fixed to the top surface of the lid body 56, the lid body 56, In addition to the gasket 57, a concave plate 59 is required, which increases the cost, increases the number of parts, and complicates the management aspects such as inventory management. Moreover, since the concave plate 59 is bonded and fixed to the top surface of the lid 56, only the annular gasket 57 cannot be separated from the lid 56 and the concave plate 59, and the annular gasket 57 is damaged. Even in this case, it is not possible to replace only the annular gasket 57, but it must be replaced together with the lid 56, and when the compact container is discarded, the lid 56, the concave plate 59 and the annular gasket 57 are replaced. It cannot be disposed of separately.

  The present invention has been made in view of such circumstances, is inexpensive, simplifies management aspects such as inventory management, can replace only an airtight elastic frame such as an annular gasket, and the lid. It is an object of the present invention to provide an airtight container capable of separating and discarding the airtight elastic frame from the container.

  In order to achieve the above object, the present invention provides a container main body having a cosmetic housing recess formed on the upper surface, a lid that covers the upper surface of the container main body, and an inner periphery of the peripheral side wall on the back surface of the lid. And an airtight elastic frame that is arranged in a ring shape along the surface and presses against the upper surface of the container main body to maintain the airtightness of the cosmetic housing recess, and is fitted to the inner peripheral surface of the peripheral side wall of the lid body. A fitting convex portion is formed, and a fitting convex portion or a fitting concave portion that is detachably fitted to the fitting concave portion or the fitting convex portion is formed on the outer peripheral surface of the airtight elastic frame. An airtight container configured to attach an airtight elastic frame to the back surface of the lid body by fitting the part and the part to be fitted is a first gist, and a container body having a cosmetic containing recess formed on the upper surface A lid that covers the top surface of the container body, and an inner peripheral surface of the peripheral side wall on the back surface of the lid An airtight elastic frame arranged in an annular shape and pressed against the upper surface of the container main body to maintain the airtightness of the cosmetic housing recess, and the lid is opened with a predetermined gap between it and the peripheral side wall of the lid A protrusion for positioning is provided from the back surface of the body, a concave portion for fitting or a convex portion for fitting is formed on the outer peripheral surface of the convex portion for positioning, and the concave portion for fitting or the inner peripheral surface of the airtight elastic frame is formed. A fitting convex portion or a fitting concave portion that is detachably fitted to the fitting convex portion is formed, and the airtight elastic frame is positioned between the peripheral side wall of the lid and the positioning convex portion, and the state The second gist is an airtight container configured to attach the elastic frame for airtightness to the back surface of the lid by fitting the fitting part and the fitted part.

  That is, the first hermetic container of the present invention includes a container main body having a cosmetic housing recess formed on the upper surface, a lid that covers the upper surface of the container main body, and an inner periphery of the peripheral side wall on the back surface of the lid. And an airtight elastic frame that is annularly arranged along the surface and presses against the upper surface of the container body to keep the cosmetic housing recess airtight. Then, a recess for fitting or a protrusion for fitting is formed on the inner peripheral surface of the peripheral side wall of the lid, and it is detachably fitted to the recess for fitting or the protrusion for fitting on the outer peripheral surface of the airtight elastic frame.
