Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a compact for containing cosmetics such as a foundation.

[Conventional technology]

In general, a compact is configured such that a lid body is hinged to be openably and closably attached to a rear end portion of a container body having a recess for accommodating cosmetics on an upper surface. An example of such a compact is shown in FIG. This compact is in a closed state by engaging an engaging projection 15 provided on the inner surface of a cutout recess 14 on the front end surface of the container body 13 with an engaging claw 17 provided on the front end portion of a lid body 16. Is supposed to hold. Then, the operation piece 18 attached to the cutout recess 14
Is pressed against the inner surface to release the engagement and open the lid.

[Problems to be solved by the device]

However, in the above compact, the structures of the engaging projection 15, the engaging claw 17 and the operating piece 18 are complicated, and errors due to molding are likely to occur. Therefore, it is possible to make one in which the above-mentioned engagement is too strong and is difficult to open the lid, and one in which it is too loose to easily open the lid. When the lid 16 is repeatedly opened and closed in the compact with a strong engagement, an excessive force is applied to the engagement claw 17 to accumulate material fatigue, and the engagement claw may be broken during use. In addition, in the compact that the engagement is too loose and the lid can be easily opened, it is possible that the lid may be opened accidentally and the inside of the bag may be soiled with cosmetics when it is carried in a bag or the like. It happens.

The present invention has been made in view of such circumstances, and an object thereof is to provide a compact that can maintain a closed state without being damaged even if the lid is repeatedly opened and closed, and has a simple structure and easy to manufacture. To do.

[Means for solving the problem]

In order to achieve the above-mentioned object, the compact of the present invention comprises a container body having a recess on the upper surface thereof and a lid body for covering the housing portion. On at least one of the back surface parts, a non-woven fabric is used as a base material and an acrylic acid-based resin layer is formed on one surface of the back surface part, and a suction sheet having the surface of the resin layer formed into a suction cup-shaped fine uneven surface is attached, A structure is used in which the closed state is maintained by utilizing the suction effect of the surface.

[Action]

The compact of the present invention is capable of maintaining the closed state without forming the engaging projection and the engaging claw for maintaining the closed state unlike the conventional compact.
That is, at least one of the upper surface of the container body and the back surface of the lid, an adsorption sheet having a suction cup-shaped fine uneven surface is attached, by the suction action of the suction cup-shaped fine uneven surface, the lid of the lid body. Holds the lid closed. As a result, unlike the conventional example described above, it is possible to stably hold the closed state and repeatedly open and close without forming the engaging claws or the engaging projections having a complicated structure. Further, unless the lid in the closed state is lifted, the suction cannot be released and the lid cannot be opened, so that the lid does not open accidentally. Even if an error occurs due to molding on the upper surface of the container body or the back surface of the lid, the suction sheet absorbs the error and always maintains a proper closed state.

Next, this invention will be described in detail based on embodiments.

〔Example〕

FIG. 1 shows one embodiment of the compact of this invention. In other words, this compact is made of plastic at the rear end of the container body 1 and also made of plastic at the rear surface.
A rear end portion of the lid body 2 to which the 2a is attached is hinge-connected. The upper surface of the container body 1 is formed with a recess 4 for accommodating the inner plate 3 accommodating the cosmetic material 3a. A flange portion 5 extending outward is formed on the outer periphery of the upper end of the container body 1. A suction sheet 7 cut into a substantially U shape is attached to the upper surface of the flange portion 5.

As shown in FIG. 2, the suction sheet 7 has a nonwoven fabric 8
(Thickness of about 0.1 to 0.2 mm) Adhesive layer 9 (thickness of about 0.1 to 0.2 mm)
.About.0.2 mm) and an acrylic acid resin layer 10 (thickness of about 0.1 to 0.3 mm) is formed on the other surface. As shown in the enlarged view of FIG. 3 (a) (magnification of 200 times) and FIG. 3 (b), the surface of the acrylic acid-based resin layer 10 is provided with a suction cup-shaped fine uneven surface 11. Recess 12a of suction cup 12
The average diameter l is 5 to 20 μm and the depth is about 1 to 5 μm. As shown in FIG. 4, the suction sheet 7 includes the adhesive layer 9 and the flange portion 5 of the container body 1.
It is attached by sticking to the upper surface of.

With the compact thus constructed, the lid body 2 is rotated from the opened state of FIG.
The 11 is brought into contact with the corresponding surface of the flange portion 6 of the lid 2.
As a result, the suction cup-shaped fine concavo-convex surface 11 is attracted to the corresponding portion of the back surface of the lid body 2 to hold the lid body 2 in the closed state. Further, when the lid is opened from the closed state, when the lid 2 is lifted up, the suction of the suction cup-shaped fine uneven surface 11 is automatically released and the lid can be opened. In this way, since the closed state can be maintained and the suction force is automatically released by lifting, in the present invention, the diameter l of the concave portion 12a of the suction cup 12, the base material of the suction sheet 7, and the suction cup formation. The type of synthetic resin used is strictly selected. That is, a layer is formed on a nonwoven fabric 8 substrate by using an emulsion of a specific acrylic acid-based resin, and by drying this, bubble-like volatilization (foaming) of water in the emulsion occurs on the surface of the layer and the acrylic acid-based resin is generated. Suction cup-shaped fine recesses 12a are formed on the surface of the layer 10 due to foaming traces. Examples of the specific acrylic acid-based resin include acrylic resin (polyacrylic acid methyl, ethyl, propyl ether) and methacrylic resin (polyacrylic acid methyl, ethyl, propyl ether), which may be used alone or in combination. . Then, as a surfactant used for emulsion of such a resin, an anionic one such as an alkylbenzene sulfonate, an alkyl sulfonate, an ether sulfonate is used. The amount of the surfactant used is set to about 1% by weight of the entire emulsion. The above-mentioned non-woven fabric substrate is not particularly limited, and various types can be used. However, the acrylic acid emulsion (solid content concentration of 30 to 60% by weight) is applied to the non-woven fabric base material, and then sprayed and dried to make the suction cup-shaped fine recesses 12a having the above-mentioned shape and dimensions become acrylic acid-based. It is formed on the surface of the resin layer 10. Then, due to the suction force of the suction cup-shaped fine recesses 12a and the slight adhesive force of the acrylic resin itself, a force for opening and closing the closed state is generated, and at the same time when the lid body is lifted, The fixing force will be automatically released. In this case, the suction sheet 7 is
When the lid is opened, it is peeled from the back surface of the lid body 2, but no adhesive component is left on the peeling trace.

FIG. 5 shows another example of the suction sheet. This suction sheet 7a has suction-disc-shaped fine uneven surfaces 11 on both sides as well as one side.
It is composed of This suction sheet 7a is attached to the upper surface of the flange portion 5 of the container body 1 by the suction action of the suction cup-shaped fine uneven surface 11, and has the same action and effect as those of the above-mentioned embodiment.

In the above embodiment, the suction sheet 7, 7a is attached to the container body 1
However, the present invention is not limited to this, and may be attached to the back surface of the lid body 2, or may be partially attached to both.

[Effect of device]

As described above, in the compact of the present invention, the suction sheet having the suction cup-shaped fine uneven surface is attached to at least one of the upper surface of the container body and the back surface of the lid.
Then, the closed state of the lid body is maintained by both of the action of adsorbing the suction cup-shaped fine uneven surface of the acrylic acid resin layer and the action of slight adhesion of the acrylic acid resin itself. Therefore, even if it is carried in a bag or the like and carried, the lid is not opened carelessly and the inside of the bag is not contaminated with cosmetics. When the lid is lifted at the time of use, the suction force of the suction cup disappears among the above-mentioned two actions and only a slight adhesive force of the acrylic acid resin itself remains, so that the lid is easily opened. . In this case, since the adhesive force of the acrylic acid resin itself is low, the adhesive component does not remain in the peeling marks, and the surface corresponding to the suction cup-shaped fine uneven surface or the finger is soiled due to the residual adhesive component. Absent. Moreover, if the adhesive strength of the resin itself is high, the adhesive strength will be reduced immediately after repeated use due to dust and the like, and it will become unusable. Inconvenient phenomenon does not occur and repeated use is possible over a long period of time.
