DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an airtight cosmetic container for easily storing cosmetics.

[0002]

2. Description of the Related Art Conventionally, a cosmetic container such as a compact type is used for carrying cosmetics. This cosmetic container stores cosmetics in a container body, and is openable and closable at a rear end portion of the container body. A hinged lid is provided, and the lid covers the upper side of the container body. The closed state of the lid is maintained by a hook mechanism provided between the front ends of the container body and the lid, and an operation button for releasing the hook mechanism is projected from the front end of the container main body. Has a general structure.

The above-mentioned cosmetic container is disclosed in, for example, Japanese Utility Model Publication No. 6-2585 in order to prevent the cosmetic contained in the cosmetic container from drying out and to maintain the quality of the cosmetic. A packing material is provided on the back side of the lid so that when the lid is closed, the packing material is pressed against the upper surface of the peripheral edge of the decorative dish to provide an airtight holding structure in the decorative dish.

Further, as disclosed in Japanese Patent Application Laid-Open No. 8-347, a cosmetic container in which an inverted U-shaped elastic packing material is attached to the periphery of the opening of the decorative dish, the lid of the cosmetic container is closed. Then, the elastic packing material provided on the lid and the inverted U-shaped elastic packing material are pressed against each other as elastic materials to exhibit high airtightness, and some deformation occurs in the elastic packing material and the container body. There is also an invention that can maintain airtightness.

In addition, in any of the above-mentioned conventional hermetic cosmetic containers, high accuracy is required for the hinged portion between the lid and the container body in order to maintain the high hermeticity of the packing material. In accordance with the above, the decorative dish is housed in a rotating frame that rotates in the container body, and the rotating frame and the lid are provided with engaging projections that can be engaged with each other. Cosmetic container that can secure sufficient airtightness in the makeup dish without being affected by the accuracy of the hinged portion between the lid and the container body by having a structure that locks the part directly to the lid Has been proposed by the applicant.

[0006]

However, in a conventional airtight cosmetic container, a hinge pin is attached to one of a container main body or a lid body in which cosmetics are stored in a fixed state in which their mounting posture does not change. A structure is adopted in which the lid is pivotally attached to the container body so as to be rotatable around the hinge pin. Further, a closed state of the lid is maintained by a hook mechanism provided between the front ends of the container body and the lid. Therefore, there are the following problems to be solved.

In other words, when deformation or dimensional variation occurs at the pivoted portion due to a manufacturing error, it directly appears as deformation of the lid, the packing, or the container body, or mutual positional displacement, and the airtight cosmetic container has This is a point that the airtightness retention performance is adversely affected.

For example, between the packing and the container body or between the lid and the packing, an inclination is generated such that the hinge pin swings in the horizontal direction in a horizontal plane including the hinge pin, or the hinge pin is forcibly moved vertically. In the case where a tilt is caused to be out of the horizontal plane by being shaken, conventionally, since there is no portion that allows a displacement corresponding to this tilt, between the packing and the container body or between the lid and the packing,
It has been difficult to correct the resulting inclination to make normal close contact with each other.

Further, when the lid is closed, the gap between the packing and the container body or between the lid and the packing is not parallel, and the inclination of the contact surface is entirely or partially viewed in the entire circumferential direction of the annular packing. When trying to obtain the required pressure contact force on one side in the diametrical direction of the packing, the pressing force becomes extremely large on the other side, and the packing in the relevant part is partially strongly compressed. There is also a problem that the pressure is not uniformly pressed in the entire circumferential direction, the airtightness is reduced, and the durability of the packing is reduced.

In view of the above, the present invention has been made in view of such a conventional problem, and the pressing force of the packing is increased by positively providing the pivotal portion provided on the container body or the lid body in the inclined direction. The present invention provides an airtight cosmetic container which expresses excellent airtightness by equalizing the whole.

[0011]

Means for Solving the Problems The present invention has been made to achieve the above object, and comprises a container body having a cosmetic storage section, and a lid for opening and closing the container body. An airtight cosmetic container in which the packing material provided on the lid in a closed state is pressed against the periphery of the cosmetic storage portion to maintain the airtightness inside the cosmetic storage portion,
The first hinge piece provided on the container body side, the second hinge piece provided on the lid body side, and the first hinge piece and the second hinge piece At least one of a hinge pin formed to be rotatably connected to the container body and the first hinge piece and / or between the lid body and the second hinge piece. One is connected by a flexible plate that allows relative movement between the container body and the lid and releases the stress caused by closing the container body with the lid. Features.

As described above, at least one of the space between the container main body and the first hinge piece and the space between the lid and the second hinge piece allow the relative movement between the container main body and the cover to allow the relative movement. The hermetically sealed cosmetic container connected by a flexible plate that releases the stress caused by closing the container body with the lid body is deformed into a pivot portion due to manufacturing errors, dimensional variation, etc. Occurs, and when it appears as deformation or mutual displacement of the lid, packing or container body, the flexible plate piece corrects these distortions by allowing deformation and mutual displacement. Then, normal contact can be performed. Therefore, it is possible to achieve excellent airtightness by equalizing the pressing force of the packing as a whole.

The hinge portion 30 has a first hinge piece 31 projecting outward from the container body 20 at two intervals at an appropriate distance from the center of the rear end of the container body 20, and a rear portion of the lid 40. At the center of the end, a second hinge piece 32 formed so as to be fittable between the first hinge pieces 31 is fitted to each other, and the hinge is straddled from both sides across the first hinge piece 31 and the second hinge piece 32. It is configured by inserting the pin 33.

On the other hand, as shown in FIGS. 1, 3 and 4, the lid 40 is based on a lid top plate 41 which forms the top plate of the hermetically sealed cosmetic container 10 when the lid 40 is closed. An annular cylindrical wall 42 is provided on the periphery of the back surface of the body top plate 41, and the first engaging protrusion 22 a is provided on the outer periphery of the cylindrical wall 42 at a position corresponding to each first engaging protrusion 22 a. The second engagement protrusions 42a are provided at three places so as to be engageable. Further, a seal projection 43 is annularly protruded from the back surface of the lid top plate 41 inside the cylindrical wall 42, and the projected position can be appropriately pressed against the seal ring R top end face F when the lid 40 is closed. It is considered as follows. In addition, an operation unit H serving as a base point for applying the opening / closing force by the user when opening / closing the lid 40 is provided in a tongue-like manner at the center of the front end on the side of the lid top plate 41.

In addition to the structure of the hermetic cosmetic container 10 described above, in the present embodiment, two protruding portions are provided protruding outward from the container body 20 at appropriate intervals around the center of the rear end of the container body 20. The first hinge piece 31 and the side wall 22 of the container body 20
Between the first and second, for example, as shown in FIG.
The connection between the hinge piece 31 and the side wall 22 is downwardly connected by a slit-shaped flexible plate SB having a predetermined notch depth and notch shape and having a predetermined thickness. Accordingly, in a situation where the slit-shaped flexible plate piece SB causes deformation such as warpage or distortion in the container body 20 or the cover body 40 when the cover body 40 is closed, for example,
The container body 20 is moved to the cover 4 by allowing various deformations occurring in the cover body 40 and the lid 40 and relative movement between the container body 20 and the cover 40.
It is possible to release the stress caused by closing at zero.

Therefore, even if the above situation occurs, the lid 4

It is possible to reliably maintain the airtightness within 0, which leads to prevention of deterioration of the cosmetic.

With the above configuration, in the airtight cosmetic container 10 of the present embodiment, the lid 40 is opened and closed around the hinge portion 30, and the lid is fully opened as shown in FIG. When closing 40, the following procedure is performed.

In FIG. 3, the lid 40 is pressed, for example, by putting a hand on the operating portion H and rotating the lid 40 forward, thereby pressing down on the second engaging projection 42a provided on the lid 40.
Is engaged with the first engagement projection 22a provided on the container body 20, and the closed state of the lid 40 is maintained. At this time, at the stage when the second engagement protrusion 42a is engaged with the first engagement protrusion 22a, the pushing force of the lid 40 causes the bulging portion T of the seal ring R to move as shown in FIG. The inner circumference of the cylindrical wall 42 is abutted, and the two are radially fitted. Mainly, the airtightness inside the container body 20 is secured by the diameter fitting, but the airtightness can also be enhanced by appropriately pressing the seal projection 43 on the back surface of the lid 40 against the top end face F of the seal ring R. I have.

Further, during or after the above-mentioned closing operation, packing or containers or containers such as the lid 40 and the seal ring R due to deformation or dimensional variation of the hinge portion 30 (pivot portion) due to manufacturing errors. When the main body 20 is deformed or displaced from each other, for example, the hinge pin 33 is swung in the horizontal direction in a horizontal plane including the hinge pin 33 between the packings and the container main body 20 or between the lid 40 and the packings. Or the hinge pin 33
Even if the liquid crystal is forcibly swung up and down and tilted out of the horizontal plane, since the slit-shaped flexible plate piece SB that allows such tilting exists, the gap between the packing and the container body 20 is formed. Alternatively, the generated inclination can be corrected between the lid 40 and the packing so that the lid 40 and the packing are brought into normal close contact with each other. The slit-shaped flexible plate piece SB is
As described above, the inclination generated as described above is allowed and eliminated by deforming itself to release the stress caused by the inclination, so that the proper closing state between the lid 40 and the container body 20 is hindered by the inclination. However, the situation does not occur.

Accordingly, the diameter fitting between the bulging portion T of the seal ring R and the inner periphery of the cylindrical wall 42 and the entire periphery of the seal projection 43 are always ensured for a long period of time to ensure uniform and sufficient airtightness. Can be done.

Next, when using the cosmetic, the first engaging projection 22a and the second engaging projection 42a are disengaged by first pushing the operating portion H of the lid 40 upward. The lid 40 is opened so that the cosmetic storage section 21 can be exposed.
