Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an airtight compact case.

[Conventional technology]

Conventionally, a compact case with airtightness has a packing disposed between the body and the lid that store volatile cosmetics, and by closing the lid, the packing is placed between the body and the lid. The cosmetics inside were tightly adhered and sealed.

However, since the airtightness is obtained by sandwiching the packing between the body and the lid, it is necessary to hold the lid in a closed state against the elastic force of the packing.
Therefore, the locking mechanism that holds the lid in the closed state and the lid opening mechanism that arbitrarily releases the locking mechanism must be made stronger.

Moreover, if the lid body is held in the closed state, there is a risk that the lid body may be deformed due to the elastic force of the packing, and the lid body and the hinge have to be firmly molded.

Further, as disclosed in Japanese Utility Model Laid-Open No. 1-108207, a fitting portion for fitting a middle plate filled with cosmetics is provided in the inner frame, and the outer periphery of this fitting portion is closely attached to the inner wall of the inner plate. A configuration has been proposed in which packing is provided to seal the cosmetic material. In the case of this configuration, since the elastic force of the packing acts not in the vertical direction but in the lateral direction, it is not necessary to firmly mold the locking mechanism, the lid opening mechanism, and the lid body 1.

[Problems to be solved by the device]

However, since the packing fits in the inner plate, it is not possible to release the tightness of the inner plate just by opening the lid, and the operation to release the fitting between the packing and the inner plate, or this fitting in the compact case. A mechanism to release the match is needed. In addition, since the packing is fitted to the inner plate when the inner plate is unsealed, upward stress is applied to the inner plate. Therefore, the inner plate needs to be held by the body so as not to drop easily upward.

[Means for solving the problem]

It is composed of at least two members, that is, a member for accommodating the inner plate 14 filled with the cosmetics 13 such as the container body 3 and a member such as the lid body 1 arranged above this member, each of which is a hinge. 4, the packing 21 for sealing the cosmetic material 13 is attached to the lower surface of the member arranged above and below so as to be openable and closable. A closed portion 23 having a V shape is provided. Further, the member for storing the cosmetic material 13 or the periphery of the cosmetic material 13 of the inner plate 14 has an inner diameter slightly larger than the outer diameter of the sealing portion 23 of the packing 21, and the sealing portion 23 enters. A veranda-shaped fitting portion (16) that comes into contact with the bottom surface is recessed. Then, the sealing portion 23 comes into contact with the bottom surface of the fitting portion 16 to expand the outer diameter, and the tip comes into contact with the side wall of the fitting portion 16 to seal the cosmetic material 13.

[Action]

When the member such as the lid 1 is closed and covers the upper surface of the member such as the container 3 for storing the cosmetic 13, the fitting portion 16 of the packing 21 is provided.
Since the tip spreads like a trumpet, the tip spreads outward by contacting the bottom surface of the fitting part 16, and the tip contacts the side wall of the fitting part 16 so that the cosmetics in the fitting part 16 13 is sealed. Here, when a member such as the lid 1 is opened, the packing is
The outer diameter of the fitting portion 16 of the fitting portion 21 is restored due to its own restoring property, the tip does not abut the side wall of the fitting portion 16, and the sealing is released.

〔Example〕

The compact case of the present invention comprises a lid body 1, an inner lid 2 and a body body 3, one end of which is openably and closably connected by a hinge 4, and from the top, the lid body 1, the inner lid body 2 and the body body 3 are arranged. Are arranged in order.

The lid 1 is provided with an applicator housing 6 for accommodating the applicator 5 such as a puff on the lower surface, and the periphery of the applicator housing 6 is a pressing portion 8. Further, a hook 10 having an engaging projection 9 is hung at the tip of the lower surface of the lid 1.

An engaging portion 17 that is held in the closed state of the lid 1 by engaging the engagement protrusion 9 of the hook 10 of the lid 1 with the top end portion of the body 3.
Is provided, and the hook 10 and the engaging portion 17 constitute a locking mechanism 18. Further, the container 3 is provided with a lid opening mechanism 19 which can release the locking mechanism 18 arbitrarily. A storage recess 11 is engraved on the upper surface of the body 3, and the storage recess 11 is further formed.
A veranda 12 is engraved around the area 11.

An inner plate 14 accommodating a cosmetic material 13 is stored in the storage recess 11 and the veranda 12. This middle plate 14 has 13 cosmetics.
And a fitting portion 16 provided at the upper end of the filling portion 15 and fitted into the veranda portion 12. It is also possible to mold the inner plate 14 only with the filling part 15 and use the veranda part 12 of the body 3 as the fitting part 16.

The inner lid 2 has a saucer 20 on which an applicator 5 such as a puff is placed.
And the mirror 7 is attached to the lower surface. Also,
A penetrating portion through which the hook 10 of the lid 1 penetrates at the tip of the inner lid 2.
22 is drilled. The inner lid 2 is in contact with the push-down portion 8 of the lid 1, and the lid 1 is closed to close the inner lid 2.
Is configured to be pressed downward.

Further, packing 21 is attached around the mirror 7.
A ring-shaped hermetically-sealed portion 23 having a C-shaped cross-section whose lower end spreads like a trumpet is hung on the packing 21. The outer diameter of the sealing portion 23 of the packing 21 is slightly smaller than the inner diameter of the fitting portion 16 of the inner plate 14, and when the inner lid 2 is closed, the outer diameter of the fitting portion 16 of the inner plate 14 becomes smaller. When the inner lid 2 is pushed in by the lid 1 when it has entered, it abuts on the bottom surface of the fitting portion 16 and spreads, and the lower end abuts the side wall of the fitting portion 16 to seal the filling portion 15 of the inner plate 14. It is configured.

In the embodiment of the present invention, the configuration in which the cosmetic 13 is arranged below the applicator 5 has been described, but the configuration in which the applicator 5 is arranged below the cosmetic 13 is conceivable. In this case, the applicator housing 6 is engraved on the upper surface of the body 3, the housing recess 11 is provided on the upper surface of the inner lid 2, and the push-down portion 8, the mirror 7, and the packing 21 are provided on the lower surface of the lid 1. There is a need.

Further, the present invention can be applied not only to a compact case in which the cosmetics 13 and the applicator 5 are housed vertically but also to a compact case in which the cosmetics 13 and the applicator 5 are housed side by side in the body 3. . In this case, the inner lid 2 may be openably and closably arranged between the body 3 and the lid 1, and the packing 21 may be placed on the inner lid 2, or the packing 21 may be directly attached to the lid 1 without providing the inner lid 2. May be placed.

[Effect of device]

As described above, according to the present invention, the packing 21 is provided with the sealing portion 23 whose tip spreads like a trumpet, and the sealing portion 23 is brought into contact with the bottom surface of the fitting portion 16 to widen the outer diameter to fit the tip. The inside of the portion 16 is brought into contact with and the inside is sealed. Therefore, unlike the case where the packing 21 is sandwiched vertically to obtain airtightness, almost no elastic force acts in the opening direction, and the locking mechanism 18 for holding the lid body 1 and the like in a closed state, The opening mechanism 19 that can release the forming mechanism 18 does not need to be rigidly configured, and the normal locking mechanism 18 and the opening mechanism 19 can be used.

Further, when the lid body 1 is closed, the packing 21 has almost no upward elastic force. Therefore, there is no risk of the lid body 1 being deformed by this elastic force, and the lid body 1 is reinforced. You don't even have to.

Moreover, since the sealing portion 23 of the packing 21 is configured to have a smaller diameter than the inner diameter of the fitting portion 16 which is a portion that abuts and obtains airtightness, the lid 1 can be opened and closed without any resistance. . However, when the sealing portion 23 comes into contact with the bottom surface of the fitting portion 16, the outer diameter of the sealing portion 23 expands, and the cosmetic material 13 is hermetically sealed only when the tip comes into contact with the side wall of the fitting portion 16. You can get it.
