Description

The present invention relates to a compact cosmetic container, and more specifically, even when the container receives an external impact (such as by being dropped), the contents (bulk) filled in the cosmetic filling tray are cracked or chipped. The present invention relates to a compact cosmetic container provided with and installed with a cosmetic shock absorbing body capable of preventing the occurrence of the shock.

Conventionally, as a compact cosmetic container for storing cosmetics such as eyeshadow, foundation, and blush, there has been provided a compact cosmetic container main body, a compact cosmetic lid for covering the compact cosmetic container main body, and the compact cosmetic. Various proposals have been made for a container body having a filling tray filled with cosmetics.

With regard to such a compact cosmetic container, it has been conventionally required to prevent the contents (bulk) filled in the filling tray from cracking or chipping even when subjected to an external impact (dropping, etc.). be.

Patent Document 1 discloses a compact container formed by hinge-joining a container body and an openable and closable lid at the rear. A compact container is disclosed which has a protrusion formed integrally with the container body and which is smaller than the bottom surface of the metal plate on the bottom surface of the recess having a shape corresponding to the shape of the plate.

In the case of the compact container of Patent Document 1, although the projections exert a shock absorbing function, the dimensions of the projections are smaller than the bottom surface of the metal plate and are molded integrally with the container body. Therefore, its impact absorption function was limited, and its function to prevent cracking of the solidified cosmetic in the metal plate was insufficient.

Patent Document 2 discloses a container body having a concave portion for accommodating a middle plate on the upper surface thereof, a lid body of the container body, and a middle plate for containing a cosmetic. A cosmetic container is disclosed in which an elastic layer made of an ultraviolet curable adhesive cured by ultraviolet irradiation is provided, and an inner plate is placed and supported on the elastic layer.

In the case of the cosmetic container of Patent Document 2, the elastic layer made of the ultraviolet curable adhesive exerts a shock absorbing function, but the layer thickness of the elastic layer made of the ultraviolet curable adhesive must be sufficiently thick. Therefore, the function of preventing cracking of the cosmetics in the middle plate was insufficient.

INDUSTRIAL APPLICABILITY The present invention realizes a compact cosmetic container that can prevent the contents (bulk) filled in the inner container for cosmetics from cracking or chipping even when subjected to external impact (for example, by dropping). The purpose of providing a compact cosmetic container body, a compact cosmetic lid covering the compact cosmetic container body, and cosmetics arranged between the compact cosmetic container body and the compact cosmetic lid body and a middle frame disposed between the filling tray and the body of the compact cosmetic container, wherein the bottom surface of the middle frame absorbs impact force when dropped. A large number of conical small projections are formed, and a wave-shaped or honeycomb-shaped shock absorption auxiliary part is formed on the side surface of the middle frame to absorb the impact force when the filling tray laterally vibrates, and the middle frame itself is formed. was realized by a configuration made of thermoplastic elastomer.

Hereinafter, a compact cosmetic container according to an embodiment of the present invention will be described in detail with reference to the drawings.

1 and 2 show a compact cosmetic container 1 according to an embodiment of the present invention. This compact cosmetic container 1 comprises an annular compact cosmetic container main body 2 and this compact cosmetic container main body 2. a compact cosmetic container lid 3 that covers the compact cosmetic container body 2 and the compact cosmetic container body 3; and a middle frame 7 disposed between the filling tray 4 and the compact cosmetic container body 2. As shown in FIGS. A large number of conical or truncated conical small projections 5 are formed on the side surface of the middle frame 7, and as shown in FIG. (or a honeycomb-shaped) impact absorption auxiliary portion 6 is formed, and the middle frame 7 itself is made of a thermoplastic elastomer.

The small protrusions 5 are formed in a conical or truncated conical shape so as to protrude from the bottom surface of the intermediate frame 7 and support the filling tray 4 at their tip portions.

By forming the small projections 5 in a conical or truncated cone shape, it is possible to gradually disperse a load such as a fall, and the formation density of the adjacent small projections 5 changes irregularly in response to an impact that is not uniform. By doing so, the effect can be exhibited regardless of the impact direction such as dropping.

Furthermore, a small amount of soft adhesive is used to bond the filling plate 4 and the small protrusions 5 so that the deformation of the small protrusions 5 is not hindered by impact. The impact can be neutralized by making it easier to peel off.

For fixing the filling plate 4, the side surface of the filling plate 4 itself is held by the impact absorbing auxiliary portion 6 on the side surface of the middle frame 7 in order to assist the soft adhesive of the small projection 5 portion.

Furthermore, it is also possible to adjust the density of the small projections 5 in order to adjust the adhesion force to a portion of the small projections 5. FIG. For example, as shown in FIG. 6, the density of the central portion of the small protrusions 5 is increased, and the density of the peripheral portions of the small protrusions 5 is decreased.

With this configuration, when the compact cosmetic container 1 is dropped downward, the pressed cosmetic moves in the removal direction, dispersing the impact of the drop and preventing damage to the pressed cosmetic.

In addition, when tilted in the left-right direction, the filling plate 4 moves due to the shape of the numerous small projections 5 and can absorb the impact, and at the same time as the energy is dispersed, the wave-shaped portion or the honeycomb-shaped portion deforms individually to disperse and absorb the impact. can do.

Next, the thermoplastic elastomer will be explained.

Regarding the injection molding of thermoplastic elastomers, thermoplastic elastomers are polymer materials that exhibit rubber elasticity at room temperature, but are plasticized at high temperatures and can be molded in the same manner as various plastics.

In addition, thermoplastic elastomers are excellent in molding processability, recycling of scraps, productivity, and energy costs required for molding processability are extremely low. Since it can be molded easily, it is most suitable for forming small conical protrusions 5 on the bottom surface of the middle frame 7 and corrugated or honeycomb shapes on the side surfaces.

By using a soft material, such a thermoplastic elastomer not only prevents the compact cosmetic container 1 from being damaged by an impact such as being dropped, but also provides a soft feel when the cosmetic is used and the surface of the cosmetic is pressed against it. be able to.

Examples of the cosmetics (bulk) M include eye shadow, foundation, and blush.

Next, drop tests performed for the present example and Comparative Examples 1 to 4 will be described with reference to Table 1 below.

The contents of the following drop test are an upright drop test and a downward drop test for each compact cosmetic container sample of this example containing a wet foundation or a dry press foundation and Comparative Examples 1 to 4. , and the side drop test, and the number of times it took for the contents to crack when dropped from a height of 50 cm was confirmed.

The results are shown in [Table 1] below.

As is clear from Table 1, the numerical value of the average number of cracks of each compact cosmetic container housing the wet foundation or dry press foundation according to this example is the same as that of each sample of Comparative Examples 1 to 4. It was found to be larger than the numerical value of the average number of cracks.

That is, this means that the compact cosmetic containers containing the wet foundation or dry press foundation of this example are less likely to crack than the compact cosmetic container samples of Comparative Examples 1 to 4. It means
