Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a compact container capable of repeatedly attaching and detaching an inner dish filled with cosmetics in a concave portion of a container body.

[Conventional technology]

In general, a compact container includes a container body having a concave portion on the upper surface, a lid for covering the concave portion, and an inner plate accommodated in the concave portion. The inner plate is fixed in the concave portion by an adhesive adhesive applied to the bottom rear surface. However, this adhesive has a drawback that it runs out of the cosmetics in the inner plate in the compact container and adheres to fingers when replacing with a new inner plate containing the cosmetics. Therefore, recently, a compact container in which the inner plate is adhered and fixed in the concave portion with a double-sided tape that does not attach an adhesive to a finger or the like has been partially adopted.

[Problems to be solved by the invention]

However, in the double-sided tape, the strength of the bonded state partially occurs depending on the bonding conditions (the pressing force, the state of the bonded surface, and the like). Therefore, the double-sided tape may remain in the concave portion of the container body when removing the inner plate from which the cosmetic has been used up from the compact container. When a new inner plate is attached to the recess with the double-sided tape remaining, there is a portion where the double-sided tape between the inner plate and the recess has two layers. As a result, there arises a disadvantage that the inner plate is housed in an inclined state and its appearance is deteriorated, and the inner plate is housed in a state of floating from the container body and the lid cannot be closed. Further, if the inner plate is frequently attached and detached from the compact container in order to change the color and the like of the cosmetic to be carried, there is a drawback that the adhesive strength of the double-sided tape is reduced and it is not possible to fix to the compact container.

Therefore, a cosmetic container disclosed in Japanese Utility Model Application Laid-Open No. 2-55810 has been proposed as a type in which an inner plate is attached without using a double-sided tape. In this cosmetic container, a suction cup having flexibility and elasticity is interposed between the inner plate and the concave portion of the container body, and the sucker is fixed to one of the inner plate and the concave portion, and the other is opposed to the other. , A gap is provided between the concave portion and the middle plate, and the middle plate is buffered and held via the suction cup. However, in this case, since a relatively large suction cup is used to buffer and hold the inner dish, the suction force of the suction cup is large and a large force is required to release the suction cup. There is a problem. In addition, since the holding of the inner plate is performed only by the suction force of the suction cup, if the suction surface of the suction cup is scratched and air enters and the suction force is lost, the suction cup itself has no adhesive force. In addition, there is no longer any means for adhering the inner plate to the recess, and the inner plate comes off from the recess, and the inner plate cannot be securely attached. Moreover, since a large force is required to release the suction of the suction cup,
There is also a problem that when the middle plate is removed, the middle plate is suddenly detached with the release of the suction, and the middle plate is easily dropped by mistake. Further, in the cosmetic container, since a large suction cup is used, there is a problem that the thickness of the compact container itself is increased, and the container is enlarged.

This invention was made in view of such circumstances,
When the middle plate is removed, no adhesive remains in the recess of the container body, the middle plate can be repeatedly attached and detached, and the middle plate can be securely attached and easily removed. The purpose is to provide.

[Means for solving the problem]

In order to achieve the above object, a compact container of the present invention includes a container main body having a concave portion on an upper surface, a lid body openably and closably provided on the container main body, and a middle plate accommodated in the concave portion, and a nonwoven fabric. A resin layer made of an emulsion type acrylic acid resin having a slight adhesive action is formed on one surface of the base material, and a large number of fine suction cup-shaped recesses are formed on the surface of the resin layer by foaming traces due to evaporation of water in the emulsion. The intermediate plate is positioned on the bottom surface of the concave portion through the suction sheet formed with the adhesive sheet, and the adhesion of the suction sheet to the resin layer itself and a large number of fine suction cups formed on the surface of the resin layer. A configuration is adopted in which the device is detachably attached to the bottom surface by the suction action of the concave portion.

[Action]

That is, in the compact container of the present invention, a resin layer made of an emulsion-type acrylic acid resin having adhesive strength is formed on one surface of the base material, and a large number of foaming traces due to the volatilization of water in the emulsion are formed on the surface of this resin layer. The suction plate formed with the fine suction cup-shaped recess is used, and the inner plate is attached by utilizing the adhesive force of the resin layer itself and the suction force of the suction cup-shaped recess. Therefore, since the suction sheet is used for mounting the inner plate instead of the double-sided tape, the suction force of the many fine suction cup-shaped recesses of the suction sheet exerts a uniform suction force on the entire surface thereof, and Even if the attachment and detachment are repeated many times, the same suction force as the initial one is maintained, so that the inner plate can be securely attached. Moreover, even if the inner plate is removed from the concave part of the container body, there is no adhesive remaining, so that when the new inner plate is attached, the inner plate may tilt or the lid may not close. Does not occur.

Also, when removing the middle plate, lift the middle plate slightly to release the suction of the suction cup-shaped recess, and then only a slight adhesive force with the emulsion type acrylic resin will remain, so it is necessary to remove it. It does not require so much force and makes it easier to remove the inner plate. Moreover, not only the suction force of the suction cup-shaped recess but also the adhesive action of the resin layer itself is used, so that even after the suction of the suction cup-shaped recess is released, the adhesion of the emulsion-type acrylic acid-based resin is obtained. Remains, so that the inner plate does not suddenly come off when the inner plate is removed, and the inner plate is not accidentally dropped. Further, since the inner plate is attached with a thin suction sheet, the thickness of the compact container itself does not increase, and the container can be downsized.

In addition, the suction sheet not only detachably fixes the inner plate to the concave portion but also has a shock absorbing effect when the compact container is dropped by mistake.

Next, the present invention will be described in detail based on an embodiment.

〔Example〕

FIG. 1 shows an embodiment of the compact container of the present invention. That is, this compact container comprises a plastic container body 1 and a plastic lid 2 which is also made of plastic.
And are hingedly connected at the rear end. A concave portion 3 is formed on the upper surface of the container main body 1, and the bottom surface 4 is formed as a mirror surface. The recess 3 has a cosmetic 5
Are accommodated in the large-diameter medium plate 6 and the small-diameter medium plate 6, respectively. Adsorption sheets 7 are respectively attached to the bottom surfaces of the inner plates 6, and the inner plates 6 are fixed to the recesses 3 via the adsorption sheets 7.

As shown in FIG. 2, the suction sheet 7 is
Adhesive layer 9 (about 0.1 to 0.2 mm thick)
~ 0.2mm), and on the other side, a synthetic resin layer 10 (about 0.1 ~
0.2 mm). This synthetic resin layer 10
As shown in the enlarged view of FIG. 3 (a) (magnification 200 times) and FIG. 3 (b), the surface of the sucker 11 has a sucker-like fine concave and convex surface 12a. Diameter l
Has an average size of 5 to 20 μm and a depth m of about 1 to 5 μm. As shown in FIG. 4, the suction sheet 7 attaches the pressure-sensitive adhesive layer 9 to the bottom surface of the bottom of the middle plate 6 and attaches the pressure-sensitive adhesive layer 9 to the middle plate 6.
The middle plate 6 is fixed to the concave portion 3 by adsorbing 11 to the bottom surface 4 of the concave portion 3.

In this compact container, the inner plate 6 is fixed to the concave portion 3 by suction of the sucker-shaped fine uneven surface 12 of the suction sheet 7, so that the inner plate 6 can be repeatedly attached and detached. Further, when the inner plate 6 fixed to the concave portion 3 is lifted, the suction of the sucker-shaped fine uneven surface 12 is automatically released, and the inner plate 6 can be removed from the concave portion 3. As described above, since the inner plate 6 can be fixed to the concave portion 3 and the suction force is automatically released by lifting the inner plate 6, in the present invention, the suction cup-shaped fine concave portion 11 of the suction cup 11 is provided.
The diameter l of a, the base material of the suction sheet 7, and the type of synthetic resin used for forming the suction cup are strictly selected. That is,
A layer is formed on the base material of the nonwoven fabric 8 with the emulsion of a specific emulsion type acrylic acid resin, and by drying this, foamy vaporization (foaming) of water in the emulsion occurs on the layer surface, and the acrylic acid resin On the surface of the layer, suction cup-shaped fine concave portions 11a are formed by the foaming traces. Examples of the above-mentioned specific emulsion type acrylic resin include polymethyl acrylate, polyethyl acrylate, polyacrylic propyl ether, polymethyl methacrylate, polyethyl methacrylate, and polypropyl methacrylate. Used. Examples of the surfactant used in the emulsion of such a resin include anionic ones such as alkylbenzenesulfonate, alkylsulfonate, and ethersulfonate, which are used alone or in combination. . The amount of the surfactant used is set to about 1% by weight of the whole emulsion. The nonwoven fabric substrate is not particularly limited, and various types are used. However, the acrylic acid emulsion (solid content concentration)
(30 to 60% by weight) and dried by spraying or the like, for the first time, the sucker-shaped fine concave portions 11a having the above-described dimensions are formed on the surface of the acrylic acid-based resin layer 10. The suction force of the suction cup-shaped fine concave portion 11a and the light adhesive force of the emulsion type acrylic acid resin itself generate a force for detachably fixing the inner plate 6 to the bottom surface 4 of the concave portion 3, and at the same time, the concave portion is formed. When the inner plate 6 is lifted from the position 3, the fixing force is automatically released. In this case, the suction sheet 7 peels off from the bottom surface of the concave portion 3 together with the inner plate 6, but does not leave an adhesive component on the peeling mark.

In the above-described embodiment, the adhesive layer 9 is attached to the bottom rear surface of the inner plate 6 and the suction sheet 7 is attached. However, the adhesive layer 9 is attached to the bottom surface of the concave portion 3 of the container body 1. The suction sheet 7 may be attached. In this case, the step of attaching the suction sheet 7 to the inner plate containing the refill cosmetic can be omitted, and the cost of the refill cosmetic can be reduced.

FIG. 5 shows another example of the adhesive sheet. The suction sheet 7a has not only one side but also both sides a sucker-like fine uneven surface 12a.
It is composed of The suction sheet 7a is attached to the back surface of the bottom of the inner plate 6 by the suction action of the sucker-like fine uneven surface 12, and has the same operation and effect as the above embodiment.

Further, as shown in FIG. 6, the suction sheets 7, 7a
The suction sheet 7 may be attached to the gripping portion 14 of the makeup chip 13 so that the suction cup-shaped fine uneven surface 12 becomes the outer surface. This makes it possible to fix the cosmetic chip 13 in the compact container.

[Effect of the invention]

As described above, in the compact container of the present invention, the inner plate is detachably attached to the bottom surface of the concave portion of the container main body via the suction sheet on which the sucker-like fine uneven surface is formed. That is, the present invention provides the above-mentioned inner plate by both the adsorption action of the suction cup-shaped concave portions distributed and formed on the surface of the emulsion type acrylic acid resin layer and the light adhesive action of the emulsion type acrylic acid resin itself. It is detachably fixed to the concave portion of the container body. Then, when the middle plate is lifted from the concave portion, the suction force of the suction cup is lost and the slight adhesive force of the emulsion type acrylic acid resin itself remains only in the above two actions. Peel from the recess.
In this case, since the adhesive force of the emulsion type acrylic acid resin itself is low, no adhesive component remains on the peeling mark, and no stain on the bottom surface of the concave portion or a finger is generated based on the remaining adhesive component. In addition, if the adhesive strength of the resin itself is high,
Repeated attachment and detachment of the inner plate causes dust and the like to adhere to it, which immediately lowers the adhesive strength and makes it unusable. However, in this invention, since the suction force of the suction cup is also used, such inconvenient phenomena do not occur. It becomes possible. Moreover, when removing the inner plate, lift the inner plate slightly to release the suction of the suction cup-shaped recess, and then only the slight adhesive force of the emulsion type acrylic acid-based resin will remain. The removal of the inner plate becomes easy without requiring great force. Moreover, since not only the suction force of the suction cup-shaped concave portion but also the adhesive action of the resin layer itself is used,
Even after the suction of the suction cup-shaped concave part is released, the adhesive strength of the emulsion type acrylic acid resin remains, so that when removing the inner plate, the inner plate does not come off suddenly, so that the inner plate is dropped by mistake. There is nothing. Further, since the inner plate is attached with a thin suction sheet, the thickness of the compact container itself does not increase, and the container can be downsized.
