Description

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

  Conventionally, various hermetic containers have been proposed as an airtight container such as a cosmetic container for containing cosmetics containing volatile components in order to maintain the airtightness of the interior. For example, there is an airtight container shown in FIG. The airtight container includes a container main body 41 having a storage portion 41a formed at the center, a middle plate 42 stored in the storage portion 41a and filled with a cosmetic 42a, and a hinge 44 on the container main body 41. An intermediate lid 43 that is connected to the container body 41 so as to open and close the storage portion 41a of the container body 41, a puff 45 placed on the inner lid 43, and the inner lid 43 and the puff 45 in a state of surrounding the pouch 45. An outer lid 46 that is screwed onto the outer periphery of the container body 41, and contacts the upper surface of the annular wall 41 b (forming the storage portion 41 a) of the container body 41 when the lid is closed. The packing 47 which contacts is fixed.

  On the outer periphery of the container body 41, a single groove 48 extending in a straight line in the vertical direction is formed, and a hinge pin 49 is installed at the lower end of the groove 48 in the horizontal direction. Further, one extension piece 50 inserted into the groove portion 48 is suspended from the peripheral edge portion of the inner lid 43, and is attached to the hinge pin 49 so as to be rotatable at the distal end portion of the extension piece 50. A rotating part 51 is formed. The hinge pin 49 and the rotation part 51 constitute the hinge 44, and the rotation part 51 has a slide part 51a that can slide up and down with respect to the hinge pin 49 as a hinge position movable mechanism. (See FIG. 33). Further, a convex portion 46a is formed on the inner periphery of the upper end portion of the peripheral wall of the outer lid 46 so as to come into contact with the upper surface of the annular seat 43a formed on the upper surface of the peripheral edge portion of the inner lid 43 when the lid is closed. .

When the outer lid 46 is screwed onto the outer periphery of the container main body 41 in the state where the storage portion 41a of the container main body 41 is covered with the inner lid 43, the outer lid 46 is screwed to some extent, When the convex portion 46a of the outer lid 46 abuts on the upper surface of the annular seat 43a of the inner lid 43 and the packing 47 is lightly pressed against the upper surface of the annular wall 41b of the container body 41, and the outer lid 46 is further screwed in, the rotating portion The inner lid 43 is pushed down together with the extension piece 50 by the slide portion 51a of the 51, whereby the packing 47 is brought into contact with the upper surface of the annular wall 41b of the container body 41 so that the adhesion is improved and the airtightness is increased. (For example, refer to Patent Document 1).
