In this known compact container, a packing is provided at the joint between the outer peripheral wall of the container body and the lid body, and when the lid body is closed, the packing is compressed and deformed to maintain the airtightness of the cosmetic storage portion in the container body. It is like this.

Further, in a compact container as disclosed in Japanese Utility Model Laid-Open No. 52-163168, an annular foamed resin packing having a tongue that is inclined downward from the outer diameter to the inner diameter is provided on the upper side wall of the lid, and the container is closed. When the lid is closed, the upper end of the peripheral edge of the container is pressed against this packing to seal the mouth of the container.

As described above, in these conventional examples, the lid is provided with the elastic packing, the lid is closed to press the packing to the upper opening of the container body, and the cushion of the packing at that time keeps the airtightness. Was there.

However, in these compact containers, the entire surface of the packing is attached in close contact with the inner surface of the lid, so if the lid itself is deformed due to molding failure such as warpage, the packing will be changed according to the deformation of the lid. Also deformed, resulting in uneven pressing force against the container body, making it difficult to maintain perfect airtightness. In addition, there is a problem that the position of the hinge pin that connects the lid and the container body is not appropriate, or even if the hook engagement is weak, the pressure force of the packing becomes uneven and it is difficult to maintain airtightness.

To solve these problems, the packing itself is made of highly flexible material, and the packing is compressed more when the lid is closed. A structure was devised that could hold the.

<Problems to be solved by the invention> However, in the compact container as described above,
Increasing the flexibility of the packing itself weakens the crimping force against the container body and makes it difficult to maintain airtightness, and if the packing is compressed too much against the container body, the lid will open even with a small shock when carrying it. There was a point.

The present invention has been made in view of the above problems, and an object of the present invention is to ensure volatile cosmetics in the container body even if there is a gap between the container body and the lid body when the lid is closed. An object is to provide a compact container that can be kept airtight.

<< Means for Solving the Problem >> In order to achieve the above object, in the present invention, a container body and a lid are pivotally attached to each other at their rear portions so as to be openable and closable, and a volatile cosmetic is provided in the container body. In a compact container in which a recess for accommodating is formed and a packing is arranged between the container body and the lid body to keep airtight, the packing body is attached to the inner surface of the lid body. The lid and the lid are pivotally attached to each other at their rear portions,
A compact container in which a recess for accommodating volatile cosmetics is formed in the container body, and a packing is arranged between the container body and the lid to hermetically keep the container. The packing is attached to the inner surface of the lid, and a gap is provided between the peripheral edge of the lid and the inner surface of the lid so that the peripheral edge can be bent up and down, and the lower surface of the peripheral edge of the packing is tapered. An annular flange is provided, the annular flange comes into contact with the inner peripheral surface of the opening of the recess when closed, and the peripheral edge of the packing bends upward to maintain airtightness. I did.

<< Embodiment >> A preferred embodiment of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 shows a compact container of the present invention, which is designated by reference numeral 10 in the drawing.

Is pivotally attached via a pin 21 so that it can be opened and closed freely.
A concave portion 11 is provided on the upper surface of 10 and a makeup plate 12 for accommodating volatile cosmetics is fitted therein. This makeup plate 12
The outer periphery of the opening 13 is a flange 14. Further, a recess 15 is provided at the front edge of the container body 10, and a first engaging protrusion 16 is integrally formed on the upper portion of the back surface of the recess 15. A claw piece 22 is vertically provided from the center of the front edge of the lid body 20 corresponding to the recess 15, and a second engaging projection 23 is integrally formed at the rear end of the claw piece 22. And the lid
When 20 is closed, the claw piece 22 enters the recess 15 and the first engaging projection 16
By engaging with the second engaging protrusion 23, the lid 20 is in a locked state.

The lid body 20 is formed so as to cover the upper surface of the container body 10, and a recess 24 is formed in the inner surface thereof, and the packing 30 is formed therein.
Is built in. The packing 30 has an area sufficient to cover the flange portion 14 of the decorative plate 12, and an annular protruding portion 31 is integrally formed on the inner side of the lid body so as to integrally protrude. An engaging protrusion 32 is formed on the outer periphery of the. Further, an annular rib 25 is formed so as to hang down in the recess 24 of the lid body 20, and an engaging concave portion 26 that is engageable with the engaging convex portion 32 is formed on the inner periphery of the annular rib 25. The packing 30 is attached to the lid body 20 by engaging with each other.

In addition, the inside of the packing 30 on the container body side is not
An annular brim 33 is integrally formed so as to project in correspondence with the opening 13 of the decorative plate 12 of 10, and the outer circumference of the annular brim 33 has a taper shape in which the diameter is temporarily reduced inward in the radial direction. Further, the peripheral edge portion of the packing 30 outside the annular protruding portion 31
34 is thinly formed, and the upper surface of the peripheral portion 34 and the lid 20 are
Since the gap 24a is provided between the lower surface of the annular rib 25 and the lower surface, the peripheral edge portion 34 can be bent upward with the lower surface of the annular rib 25 as a fulcrum. Further, an annular plate 35 is attached to a peripheral wall of the lid body 20 that defines the void portion 24a so as to face a peripheral end portion of the packing 30 to prevent the packing 30 from dropping downward.

In the compact container having the above-mentioned structure, even if a gap G occurs due to a dimensional error between the container body 10 and the lid body 20 when the lid body 20 is in the closed position, as shown in FIG. The annular brim 33 of 30 is fitted into the opening 13 of the decorative plate 12 and comes into pressure contact with the inner peripheral surface thereof. At this time, since the outer circumference of the annular flange 33 is tapered, the annular flange 33 flexibly corresponds to the inner peripheral surface of the opening 13 of the decorative plate 12, and the inside of the decorative plate 12 is sealed. Also, as shown in FIG.
In the portion where there is no gap G between the cover 20 and the lid 20, the annular collar 33 of the packing 30 tries to enter deeply into the opening 13 of the decorative plate 12 and presses strongly against the corner of the opening 13, so that the peripheral edge of the packing 30. With the lower surface of the annular rib 25 serving as a fulcrum, 34 bends and bends slightly upward in the void 24a. As a result, the annular collar 33 can maintain an appropriate pressure bonding force on the inner peripheral surface of the opening 13 of the decorative plate 12.

FIG. 4 shows an essential part of a compact container according to a second embodiment of the present invention. In this embodiment, an annular small protrusion 36 is provided on the outer surface of the annular collar 33 on the lower surface of the peripheral edge portion 34 of the packing 30. The protrusion 36 is adapted to come into pressure contact with the upper surface of the peripheral flange portion 14 of the decorative plate 12 when the lid body 20 is closed. The other structure is substantially the same as that of the first embodiment, and therefore omitted. This second
The structure of the embodiment is suitable when the packing 30 is selected from a softer material than the case of the first embodiment. In the state shown in FIG. 4, the annular small protrusion 36 strongly presses against the peripheral flange portion 14 of the decorative plate 12. As a result, the peripheral edge portion 34 of the packing 30 is bent upward, and even if a small gap is created between the lid body and the container body due to their deformation or dimensional error, the annular small protrusion 36 is deformed. Can be absorbed to seal the interior of the decorative plate.

<Effect> As described above, in the compact container according to the present invention, the container body and the lid are pivotally attached to each other at their rear portions so as to be openable and closable, and the container body is provided with a recess for storing volatile cosmetics. Along with forming the packing, the packing is attached to the inner surface of the lid, and a gap is provided between the peripheral edge and the inner surface of the lid so that the peripheral edge can be bent up and down. The lower surface of the peripheral edge of the packing is tapered. Since an annular flange is provided, the annular flange comes into contact with the inner peripheral surface of the opening of the recess when closed, and the peripheral edge of the packing bends upward to keep airtight, so that the container body or the lid body Even if deformation occurs or the hinge position shifts, and the deformation dimension error occurs, the peripheral edge of the packing is bent and deformed, so that the proper crimping force of the annular flange fitted on the inner peripheral surface of the decorative plate can be maintained. Done, airtight Can be held reliably. Further, even if a material having a high flexibility is not used as the material of the packing, a material having a certain degree of flexibility may be used, and a wide range of materials can be selected according to the cosmetic material.
