  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. Is formed (see FIG. 14). 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. . In addition, when the container body 41, the inner lid 43, the outer lid 46, etc. are manufactured, even if an error occurs in the vertical dimension such as an error in the thickness of the inner lid 43, the vertical dimension error is caused by the hinge position movable mechanism. Can be absorbed (see, for example, Patent Document 1).

  However, in the above airtight container, before the outer lid 46 is screwed, when the inner lid 43 is rotated downward to cover the storage portion 41a of the container main body 41, the rotating portion 51 is provided with a hinge position movable mechanism. Therefore, as shown in FIG. 14, the extension piece 50 of the inner lid 43 is positioned slightly above, and the inner lid 43 is inclined (the portion near the extension piece 50 is on the upper side, and the opposite portion of the extension piece 50 is Is placed on the annular wall 41b of the container body 41. When the outer lid 46 is screwed in such a state, the inner lid 43 may be closed with the inclined posture, and there is a gap between the inner lid 43 in the inclined posture and the annular wall 41b of the container body 41. And airtightness is reduced. In addition, since the pivot position 51 is provided with a hinge position movable mechanism, the inner lid 43 is likely to rattle during makeup or the like in the open lid state. This rattling causes the hinge pin 49, the pivot portion 51, etc. Damage early. Moreover, the hinge position movable mechanism cannot absorb the horizontal dimension error even if it can absorb the vertical dimension error.

  The present invention has been made in view of such circumstances, has excellent airtightness, can eliminate shakiness of the inner lid, and can absorb both vertical and horizontal dimensional errors. The purpose is to provide an airtight container.

In order to achieve the above object, an airtight container according to the present invention includes a container main body having a content receiving recess formed on the upper surface, a lid that covers the entire container main body, and the content receiving recess in a closed state.
