The mold cover B is fitted around the outer periphery of the lipstick, and the two are inverted, and the mold cover B and the lipstick support portion Aa are filled with an appropriate amount of molten cosmetic and hardened, so that the small stick lipstick E is formed. Then, the bottom plate C is fitted to the lower end of the base cylinder A, the mold cover B is removed, and the cap D is removably fitted to the outer periphery of the lipstick support portion Aa of the base cylinder A. It is assembled as a stick-shaped lipstick container (trade name "Yves Saint Laurent").

[0003]

However, this sample lipstick can actually be used only in a small part protruding outside, and many parts are located in the lipstick support part Aa and cannot be used. There are many disadvantages. The present invention seeks to eliminate such disadvantages, and
The purpose is to facilitate the assembly.

[0004]

In order to achieve the above-mentioned object, the invention according to the first aspect of the present invention relates to a stick-shaped cosmetic sample container, wherein an upper end portion is formed in a stepped small diameter portion 11 and an upper end inner edge of the stepped small diameter portion. A base cylinder 1 having an engaging ridge 12 formed thereon, and an engaging groove 21 for engaging with the engaging ridge 12 are provided in the middle part of the outer periphery, and the middle part of the outer periphery and below the stepped small-diameter part. A cosmetic support tube 2 fitted and engaged with the inner periphery of the mold 11, a mold cover 3 detachably fitted to the outer edge of the upper end of the cosmetic support tube, and a detachably fitted outer periphery of the upper end of the stepped small diameter portion 11. And a cap 4 to be formed.

The invention according to a second aspect of the present invention relates to a method of assembling a rod-shaped sample container for cosmetics.
2. After the mold cover 3 is detachably fitted to the outer periphery of the upper end of the cosmetic support tube 2 according to claim 1, which is fitted to the inner periphery of the upper end of the mold cover 3, the coupling is inverted and the mold cover 3 or the cosmetic support tube is inverted. 2 is filled with an appropriate amount of molten cosmetic and cured to form a small stick-shaped cosmetic 5;
The base tube 1 is located at the middle part of the outer periphery of the cosmetic support tube 2
The engaging ridge 12 is fitted into the engaging concave groove 21 on the inner periphery of the upper end of the base cylinder 1, the mold cover 3 is removed, and the cap 4 is detachably attached to the outer periphery of the upper end of the base cylinder 1. It is characterized by being fitted.

[0006]

According to the first aspect of the present invention, the cosmetic support tube 2 fitted to the inner periphery of the upper end of the base tube 1 has a short length and a small inner diameter. In addition to minimizing the unsupported portions as much as possible, the filling of the molten cosmetics is facilitated. Further, the fitting engagement between the engaging ridges 12 of the base cylinder 1 and the engaging grooves 21 of the cosmetic support cylinder 2 enables a precise connection which is not easily disengaged by an external force. Claim 2
According to the invention, easy assembly is enabled.

[0007]

1 and 2 show an embodiment of a stick-shaped cosmetic sample container according to the present invention and an assembling method thereof. In the figure, reference numeral 1 denotes a base cylinder having an upper end portion formed in a stepped small-diameter portion 11 and an engaging ridge 12 formed on the inner edge of the upper end of the stepped small-diameter portion. The cosmetic support cylinder 3, which is provided with an engaging concave groove 21 to be engaged with the outer peripheral part and the lower part of the outer periphery is fitted to and engaged with the inner peripheral of the stepped small diameter part 11,
The mold cover 4, which is detachably fitted to the outer edge of the upper end of the cosmetic support cylinder, is a cap which is detachably fitted to the outer periphery of the upper end of the stepped small-diameter portion 11, all of which are made of synthetic resin. . The cosmetic support tube 2 is formed such that the middle portion to be fitted into the stepped small-diameter portion 11 of the base tube 1 is formed thick to form the engagement groove 21 and the outer periphery below the engagement groove is fitted. It is tapered for convenience of insertion.

[0008] The assembly is performed according to the steps (1) to (4) shown in FIG. That is, (1) The mold cover 3 is fitted to the outer edge of the upper end of the cosmetic support tube 2, and the two joints are inverted, filled with an appropriate amount of molten cosmetic, and cured. Thereby, the small stick-shaped cosmetics 5 are formed inside the two parts. (2) The lower part of the outer periphery of the cosmetic support tube 2 is fitted to the inner periphery of the stepped small-diameter portion 11 of the base tube 1, and the engaging convex portion 12 and the engaging concave portion 21 are engaged. (3) The mold cover 3 is removed to expose the small stick-shaped cosmetics 5. (4) The cap 4 is detachably fitted to the outer periphery of the stepped small-diameter portion 11 of the base cylinder 1 to complete the assembly.

The small stick-shaped cosmetic 5 refers to various cosmetics suitable for sticking, in addition to lipstick.

[0010]

According to the first aspect of the present invention, since the cosmetic support tube 2 is fitted to the inner periphery of the upper end of the base tube 1, the cosmetic support tube 2 can have a short length and a small inner diameter. Therefore, most of the small bar-shaped cosmetics 5 can be projected to the outside, and the unusable supporting portions can be significantly reduced, and waste can be eliminated. Further, the short and small cosmetic support tube 2 facilitates filling of the molten cosmetic, shortens the filling time, and improves workability. Further, an engaging ridge 12 is formed on the inner edge of the upper end of the base tube 1 formed in the stepped small diameter portion 11, and an engaging concave groove 21 is provided in the middle of the outer periphery of the cosmetic support tube 2, and the two are engaged. As a result, the base cylinder 1 and the cosmetics supporting cylinder 2 can be accurately coupled to each other, can be easily detached by an external force, and can be conveniently used and handled.

Further, according to the second aspect of the present invention, since the above configuration is employed, assembly can be performed easily and an inexpensive product can be provided.
