Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a compact container that airtightly stores a wet cosmetic to prevent it from drying out.

<Prior Art> Conventionally, an "airtight compact container" has been disclosed in Patent Application Publication No. 145807/1983 as a compact that ensures airtightness and prevents solid or powdered cosmetics from dissipating or volatilizing.

The compact of this invention houses an "elastic gasket that shuts off the inside and outside of the container when it is closed" in (1) a groove provided in the top or bottom lid, and the top edge protruding outside the groove is placed below. Press it against the lid or top lid. (2) Circulate only around the outer periphery of the recess containing the cosmetics. (See Figures 1-3). (3) The inner cover is supported swingably between the upper and lower covers by providing a certain space with respect to the upper cover, and the periphery of the inner cover is pressed against the upper surface of the lower cover as an elastic packing ( (See Figure 4). (3.
1) The inner lid is supported by a support shaft parallel to the hinge pins of the upper and lower lids, and is held between the inner lid and the upper lid via a leaf spring (see FIG. 5). (3.2) The center part of the inner lid is swingably supported on the upper lid, and an elastic packing is wound around the outside of the cosmetic storage recess (see FIG. 6). (4) The inner tray for storing cosmetics is made of an elastic material, and the upper part of the periphery of the inner tray is made of elastic packing (see FIG. 7).
A variety of closure configurations are disclosed to prevent the tendency of the elastic gasket to be compressed and deformed from the portion near the hinge toward the free direction of the lid when the container is closed.

<Problems to be solved by the invention> The invention of the above-mentioned prior art is based on a compact container.
It has a structure in which an elastic packing is provided between the lower lids with or without an inner lid, but the structure of the elastic packing itself is simply a narrow annular body, which (1) is shaped like a flat plate when the upper and lower lids are closed. (See Figures 1 to 4 and Figures 6 and 7). (2) The purpose of the elastic packing shown in FIG. 5 is to prevent deformation of the elastic packing by coming into pressure contact with the upper end surface of the narrow inner plate.

Therefore, if the inner surface of the upper lid, the upper surface of the lower lid, and the lower surface of the inner lid are not completely flat, or if there are variations in the density of the elastic packing material or the fit with the recess, the inner plate will not be completely airtight. Compact containers usually have holes in the joints between the top and bottom lids and in the hooks for opening and closing the lid, which means that the inside of the container communicates with the outside air, making it impossible to completely seal the cosmetics. In particular, a high degree of manufacturing precision is required for pressure contact between the narrow elastic packing and the upper end surface of the peripheral edge of the inner plate, and if the precision is poor, the same defects as described above will be exposed.

The present invention aims to eliminate the drawbacks of the conventional compact containers and provide a structure that can hold moist cosmetics without drying them out.

<Means for Solving the Problems> The compact container of the present invention is provided with an annular protrusion on the inner surface of the lid for attaching a gasket and a gasket holder, and the gasket has an outer peripheral edge with a flange-shaped cross section, Furthermore, the rim is integrally protruded in the vertical direction,
A large-diameter mounting hole is provided in the center to fit externally into the annular protrusion, and the mounting hole is fitted and fixed to the annular protrusion on the inner surface of the lid. The top surface has a mounting protrusion that is fitted into the annular protrusion of the lid, and the seal fixed on the inner surface of the lid is held down and the mounting protrusion is internally fitted into the annular protrusion of the lid. The lid, packing, and packing retainer are fixed together. In the container, a flange-equipped inner plate wider than the flange of the packing is fitted into a recess on the upper surface for attaching the inner plate, and the wet cosmetic is contained therein, and the container and the lid are rotatably connected at one end by a pivot. The other end of the lid and the container are opened and closed so that when the lid is closed, the upper and lower end surfaces of the outer periphery of the flange are in pressure contact with the inner surface of the lid and the flange of the flanged inner plate.

Forcibly hang the sliding body 4 on the front end of the spring 4'
Due to its elasticity, it is inserted and held in the sliding recess 2b so that it cannot be detached from the front and the outside.

The lid 3 has a hanging hook piece 3a hanging from its front end and a lid rotation base 3b hanging from its rear end, which passes through the shaft hole 3b' of the mounting shaft 8. In the figure, 1b'', 4c, 3a' and 4e are hanging protrusions, 1b' and 4a' are pressure surfaces, and the hanging protrusions 1
It acts to completely release the corresponding position of the support between "b" and 4c.The sliding and support ranges of both pressure surfaces and each support protrusion are set to be small.

An annular protrusion 3e for attaching the seal 5 is provided on the inner surface of the top plate of the lid 3, and the inner periphery thereof serves as a recess 3c' for fitting the seal holder 6. The gasket 5 has elasticity, has an inverted plate-shaped cross section with a flange, has a flange edge 5a with an oval cross section protruding vertically on the outer periphery, and has a central attachment hole 5b connected to the outer periphery of the annular protrusion 3c of the lid 3. After fitting the mounting protrusion 6a protruding from the back side of the seal holder 6 to the inner periphery of the annular protrusion 3c of the lid and positioning each other, the seal 5 and the seal are attached to the inner surface of the lid using ultrasonic waves. The flat parts of the presser foot 6 are firmly and airtightly attached to each other.
Note that the bonding means may be other than the ultrasonic bonding.

The lid rotation base 3 of the lid 3 is inserted between the lid mounting protrusions 1c and 1c of the lower container fitted into the notch 2c of the upper container 2.

Both ends of the tightening spring are elastically inserted into the recess 3b'' of the lid rotation base and the cutout recess 2c' of the upper container.The supporting hook piece 4d of the sliding body is a plate spring. It is hung on the front end of the horizontal groove 2f on the bottom surface of the upper container with a biasing force of 4'.

The upper and lower containers and the lid of the above structure are connected as shown in Fig. 2, and the upper and lower containers 2,
1 and the lid 3 are respectively hung on the sliding body 4, and the inner plate 9
The flange 9a is fitted into the recess 2a on the upper surface of the upper container 2, and the flange edge 5a of the gasket 5 fixed to the back of the lid has a wall thickness narrower than the width of the flange 9a of the inner plate, and is connected to the back of the lid and the inner plate. It is elastically in close contact with the upper surface of the collar of No.9. The inner surface of the lid,
Even if there is a shape distortion or dimensional error in the flange, packing, etc. of the inner plate, it can be bent due to the elasticity of the packing, the bent cross-sectional shape of the inverted plate shape with a flange, and the cross-sectional shape of the outer flange edge 5a. It absorbs distortion, and even if the outer diameter of the gasket is larger than the one shown in the illustration and the upper surface of the flange of the inner plate is pushed outward in the outer circumferential direction by the pressure when the lid is closed, the flange edge 5a
is narrower than the width of the brim of the inner plate, and is in contact with the inner edge of the brim, so it does not rest on the upper end surface of the upper container, and always stays in elastic contact with the upper surface of the brim of the inner plate, and remains inside the inner plate. It is designed to keep moist cosmetics airtight.

To open the lid 3, when the finger rest 4a of the sliding body is pushed inward against the outward biasing force of the leaf spring 4', the inclined surface of the pressure surface 4a' at the lower end is pressed against the pressure surface 1b' of the lower container. The lower container and the upper container do not have the elasticity to expand, so they do not release voluntarily, and the sliding member 4 is pushed further. Then, the lower container 1 is pushed open by the slopes of both pressurizing surfaces 4a', 1b', and even if you release your fingers in this state, the two hooking support protrusions 1b'', 4c are out of the engaged position and can be opened freely. Become. It can be opened in this state, or in a state where the pressure surfaces 1b' and 4a' are in contact, but the hanging projections 3a' and 4e are also unlatched at the same time, and the lid 3 opens immediately due to the expansion elasticity of the tightening spring 7, so the inside of the lower container The user can take out the puff and apply the wet solid cosmetic 10 filled in the inner tray 9 to apply makeup.

After use, when the lid 3 and the lower container 1 are clamped at their front ends toward the upper container 2 and closed, the hanging support hook piece 3a and the hanging support projection piece 1b enter the sliding body 4 oppositely, The upper and lower hanging protrusions 4c and 4e of the sliding body and the hanging hook piece 3a of the lid resist the biasing force of the leaf spring 4'.
The hanging protrusion 3a' of the lower container and the hanging protrusion 1b'' of the hanging protrusion 1b of the lower container are respectively hung to close the lid.In this case, the hanging hook piece 4d of the sliding body is attached to the leaf spring 4'. The retracting action causes the lid 3 to slide rearward in the lateral groove 2f, and is immediately suspended in the state shown in FIG. Hold securely.

<Effects of the Invention> The compact container of the present invention having the above-described structure and function has the following advantages: (1) The lid that covers the cosmetic needs to be airtight because it is necessary to keep the moist cosmetic that hates dryness in a moist state at all times; ), the adhesive is attached to the inner surface of the lid by airtightly bonding the adhesive, adhesive, and lid, and when the lid is closed, the upper surface of the flange on the periphery of the inner tray filled with wet cosmetics and the adhesive on the inner surface of the lid are attached. The outer periphery of the flange is in close contact with the outside air inside the inner tray, as well as the lid and the inside of the container, which are blocked from ventilation. 2. Even if there is an error or distortion in the shape or dimension of the packing or the inner plate, the bent shape of the inverted plate-shaped cross section of the packing and the protruding shape of the outer circumferential flange will allow it to flex, and the size and shape will be corrected. Errors and distortions can be absorbed, and since the inner surface of the lid and the flange of the inner plate are always kept in close contact with each other, airtightness is completely maintained.
