That is, the airtight container 10 of the present embodiment is shown as an example when it is configured as a portable cosmetic container as shown in FIGS. 1 and 2, and a storage portion 11a is provided at the center. A so-called jar type container comprising a container body 11, an inner lid 12 for opening and closing the storage portion 11a, and an outer lid 13 surrounding the inner lid 12 and screwed to the outer periphery of the container body 11. Is done.

The container body 11 is formed in a circular shape, and its peripheral edge is provided with an inner wall 11b constituting the inner periphery of the storage portion 11a, and the outer wall 11c is folded down from the upper end of the inner wall 11b so that the outer wall 11c hangs down. The inner wall 11b and the outer wall 11c form a double wall structure. At this time,
The upper end of the inner wall 11b is formed to be one step higher than the upper end of the outer wall 11c, and the inner lid 12 abuts on the raised upper end of the inner wall 11b to seal the inside of the storage portion 11a filled with the unillustrated cosmetic. The outer lid 1 is provided on the outer periphery of the upper end of the outer wall 11c.
A male screw portion 14 for screwing the male screw 3 is formed, and a lower portion of the portion where the male screw portion 14 is formed is an enlarged diameter portion 11d which bulges outward.

The inner lid 12 is formed in a circular shape to be fitted inside the outer lid 13, and has an annular seat 12a protruding in a trapezoidal cross section on the upper surface of the peripheral edge, and a container on the bottom surface. A circular recess 12b having a slightly larger diameter than the inner wall 11b of the main body 11 is formed, and a packing 15 is fitted and fixed in the circular recess 12b. In addition, on the lower surface of the peripheral portion of the inner lid 12, a pivot 16 is vertically suspended from the inner lid 12 at a position corresponding to between the inner wall 11 b and the outer wall 11 c.

On the other hand, the inner wall 11b of the container body 11 and the outer wall 1

By inserting the rotation support shaft 16 into the hole 17, the inner lid 12 is supported rotatably about the rotation support shaft 16. At this time, an enlarged diameter portion 17 a having a slightly larger diameter is formed in the lower half of the fitting hole 17, while the rotation support shaft 16 is formed.
A large-diameter conical portion 16a having a tapered portion is formed at the tip of the conical portion 16a, and the conical portion 16a can be reduced in diameter by a split groove 16b.

Therefore, by inserting the pivot 16 into the fitting hole 17 from above, the conical portion 16a is inserted into the fitting hole 17 while being reduced in diameter, and the entire conical portion 16a is fitted. When the conical portion 16a is located at the enlarged diameter portion 17a of the hole 17, the diameter of the conical portion 16a is increased by the elastic force, and the conical portion 16a is engaged with the stepped portion 17b. By the way, in a state where the conical portion 16a is located inside the enlarged diameter portion 17a, the packing 15 of the inner lid 12 comes into contact with the upper end of the inner wall 11b.

Then, as described above, the packing 15 is attached to the inner wall 1.
In the state of contact with the upper end of the rotation support shaft 1b, the rotation support shaft 16 is provided with a margin portion 16c further protruding from the upper end of the fitting hole 17, and the rotation support shaft 16 is further pushed by the margin portion 16c. The movement in the direction is allowed.

The outer lid 13 is formed from a peripheral edge of a circular top plate 13a through a chamfered inclined portion 13b.
Is formed in an inverted U-shaped cross section, and a female screw portion 18 is formed on the inner periphery of the peripheral wall 13c to be screwed into the male screw portion 14 formed on the outer wall 11c of the container body 11. Also,
Four protrusions 13d are formed at equal intervals in the circumferential direction on the inner side of the inclined portion 13b. When the protrusion 13d is screwed to the container body 11 and moved to some extent in the screwing direction, The inner lid 12 comes into contact with the upper surface of the annular seat 12a. The protrusions 13d are formed intermittently at appropriate intervals in the circumferential direction, but may be formed in a continuous annular shape without limitation.

Further, when the outer lid 13 is completely screwed, the lower end of the peripheral wall 13c stops near the upper end of the enlarged diameter portion 11d of the container body 11, and the outer lid 13 and the enlarged diameter portion 11d By making the outer diameters of the containers substantially equal, the entire container has the same diameter and the appearance thereof is improved.

Accordingly, in the airtight container 10 of the present embodiment having such a configuration, the inner lid 12 is inserted into the housing 1 while the rotation support shaft 16 is inserted into the fitting hole 17 of the container body 11 as shown in FIG.
The opening 1a is assembled so as to cover the opening, and the outer lid 13 is screwed onto the male screw portion 14 of the container body 11 by surrounding the inner lid 12 from above. In addition, the outer lid 1
A predetermined space is provided between the outer lid 13 and the inner lid 12 in a state where the screw 3 is screwed, and the puff 19 is stored in this space.

When using the cosmetic filled in the storage portion 11a, the outer lid 13 is first removed from the airtight container 10 and then the inner lid 12 is pivoted about the pivot 16 as shown in FIG. As a result, the storage portion 11a is opened to expose the cosmetics, and the cosmetics are scooped by the puff 19 and used. Then, when the makeup is completed and the airtight container 10 is to be closed, the container 1 is rotated based on the inner lid 12 and the storage portion 1 is rotated.
After covering the opening of 1a, the storage part 11a is double-closed by the inner lid 12 and the outer lid 13 by covering the outer lid 13 from above and screwing it into the container body 11 and screwing it. It has become.

As described above, when the container body 11 is closed by the inner lid 12 and the outer lid 13,
The opening 1 a is closed by the packing 15 of the inner lid 12. That is, the female screw portion 18 of the outer lid 13 is screwed into the male screw portion 14 of the container body 11, and when this is screwed to some extent, the projection 13 d of the outer lid 13 comes into contact with the upper surface of the annular seat 12 a of the inner lid 12. When the outer lid 13 is further screwed in from this state, the screwing force is applied from the annular seat 12 a to the inner lid 12.
, Whereby the packing 15 is pressed against the upper end of the inner wall 11b, which is the opening of the storage portion 11a.

In this embodiment, when the screwing force of the outer lid 13 is applied to the inner lid 12, the pivot 16 for rotatably supporting the inner lid 12 is movable in the axial direction. As a result, the extra portion 16c is pushed into the fitting hole 17 so that the inner lid 12 can be entirely pushed down. That is, when the inner lid 12 is simply closed as shown in FIG. 4A, the packing 15 is lightly abutted on the upper end of the inner wall 11b. When the screwing force of the outer lid 13 is input to the inner lid 12, the rotation support shaft 16 moves downward in the fitting hole 17 as shown in FIG. It will be pushed down as a whole. For this reason, the packing 15 can apply a pressing force uniformly over the entire circumference between the packing 15 and the upper end of the inner wall 11b, so that the sealing followability is improved and the airtightness of the storage portion 11a is improved. Is significantly increased.

Therefore, the housing 11a is sealed by the packing 15 in this manner, so that the housing 11a is closed.
It is possible to prevent volatilization and the like of the cosmetics filled therein, thereby preventing its deterioration. Further, since the packing 15 does not come into contact with one side, the durability of the packing 15 itself can be improved.

In this embodiment, the packing is used. However, the packing may be omitted, and the bottom surface of the inner lid may directly contact the upper end of the inner wall. Also,
Although the case where the cosmetic is directly filled in the storage portion 11a has been disclosed, the present invention is not limited to this, and the intermediate plate (not shown) is filled with the cosmetic, and the intermediate plate is detachably fitted into the storage portion 11a. Can also be used. Needless to say, the items stored in the storage portion 11a are not limited to cosmetics.
