Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a molding container for molding solid cosmetics such as lipstick, lip balm, stick eye shadow, and stick foundation into a predetermined shape.

``Prior art'' Conventional containers for forming lipsticks, etc. have a relatively long and narrow shape with a tapered shape in order to form the external shape of the lipstick, etc.
Cap-shaped capsules with an open bottom were used. For this reason, when a capsule that has been used for molding is reused, its inner surface is tapered, so tools such as brushes are used to clean the inner surface, but it is difficult to clean the tip of the inner surface, and most of the capsules are disposable. The disadvantage was that it was uneconomical.

``Object of the Present Invention'' In view of the above-mentioned conventional drawbacks, the present invention is to provide a molded container for lipstick, etc., which is easy to clean after molding and can be used repeatedly.

"Means for Achieving the Object of the Present Invention" The present invention comprises an outer case body having an open bottom and at least one communication hole communicating with the atmosphere at the top;
The outer case is molded of a non-expandable soft resin with a shape that comes into contact with the inner surface of the outer case body, and a bottom part is formed integrally with the lower end of the outer case body, and air, etc. is inserted through the communication hole of the outer case body. an inner case body that molds the outer circumferential shape of a bag-shaped lipstick or the like that can be positioned outside the opening of the body;
It is characterized by comprising an engaging part formed in the opening of the bottom of the outer case and removably engaged with the upper part of the inner tray for holding cosmetics such as lipstick in the storage container.

"Embodiments of the present invention" The present invention will be described in detail below with reference to embodiments shown in the drawings.

In the embodiment of the present invention shown in FIGS. 1 to 4, 1a is an outer case body with an open bottom, and this outer case body 1 has a communication hole 3 in the upper part communicating with the atmosphere.
A is provided.

Reference numeral 2 denotes a bag-shaped inner case body which is molded from a non-expandable soft resin and has a shape that comes into contact with the inner surface of the outer case body 1a, and whose bottom portion is integrally formed with the lower end portion 4 of the outer case body 1a. This inner case body 2 is made to move outwardly from the opening 6a of the outer case body by inserting air or the like between the outer case body 1a and the inner case body 2 through a communication hole 3a provided in the outer case body 1a. It is formed so that it can be positioned.

Further, 5a is a molded product having an outer peripheral shape formed by the inner case body 2.

Reference numeral 12 denotes an engaging portion formed in the opening 6a at the bottom of the outer case body 1 and removably engaged with the upper engaging portion 27 of the inner tray 11 that holds cosmetics such as lipstick in the storage container 20.

Note that the lipstick storage container 20 includes a hook member 15 in which a cap fitting portion 14 is formed on the outer periphery of the upper portion.
An inner cylindrical member 17 is formed with an axial notch 16 whose lower end is inserted and fixed into the hakama member 15, and a spiral groove 18 is formed to cover the outer periphery of the inner cylindrical member 17. A spiral member 19, an outer cylinder member 21 that covers the outer circumference of the spiral member 19, a notch 16 of the inner cylinder member 17 that moves up and down within the inner cylinder member 17, and a spiral groove 18 of the spiral member 19. Support member 23 equipped with an engaging pin 22 on its outer periphery
and a cap 24 that covers the outer periphery of the outer cylindrical member 21 and fits into the cap fitting portion 14.

Reference numeral 25 denotes an engagement portion formed on the plate member 11 and removably engaged with the engagement portion 26 of the support member 23 .

The molding container 10a configured in this manner has the inner case body 2 in contact with the inner surface of the outer case body 1a,
After the dish member 11 is engaged with the outer case body 1a, the melted lipstick 5a is filled through the opening 28 of the dish member 11.

Molding container 10 in which lipstick 5a is filled and solidified
A is set in the lipstick storage container 20, but when setting it, first hold the hook member 15 with one hand and hold the outer cylinder member 21 with the other hand and rotate the support member. 23 as lipstick container 2
0, and the molding container 10a with the plate member 11 engaged is inserted into the upper opening 2 of the lipstick container 20.
The plate member 11 is inserted into the lipstick container 20 from 9, and the engaging portion 25 formed on the plate member 11 and the support member 23 are inserted.
The engaging portion 26 formed in the above is engaged.

After that, by holding the hakama member 15 and the outer cylinder member 21 and rotating them, the dish member 11 and the lipstick 5 are separated.
a can be placed into the lipstick container 20 at any time as shown in FIG.

On the other hand, the molding container 10 after the lipstick 5a is placed in the lipstick container 20 and removed from the lipstick container 20.
As shown in FIG. 4, a is a nozzle engaging portion 13 that removably engages with a nozzle engaging portion of an air insertion device provided in a communication hole 3a with the atmosphere in the upper part of the outer case body 1a. By engaging the air nozzle 8a and inserting air between the outer case body 1a and the inner case body 2 to form an air chamber 9a, the inner case body 2 is inserted into the outer case from the opening 6a of the outer case body 1a. It can be located outside the body 1a.

This makes it possible to easily clean the inner surface of the molding container, which was conventionally difficult to clean due to its tapered shape.

When reusing the outer case body 1
By extracting the air inserted between the outer case body 1a and the inner case body 2 through the upper communication hole 3 of a, the inner case body 2 can be brought into contact with the inner surface of the outer case body 1a, and the state can be reused. becomes.

"Different Embodiments of the Present Invention" Next, different embodiments of the present invention shown in FIGS. 5 to 8 will be described. In the description of these embodiments, the same components as those of the embodiments of the present invention are denoted by the same reference numerals and redundant explanations will be omitted.

In the embodiments shown in FIGS. 5 to 8, the main difference from the embodiments of the present invention is that the inner case body 2b
The molding container 10b configured in this manner has a convex or concave pattern 30 on the inner surface 7b of the molding container 10b.
In this method, an effect can be obtained in that an uneven pattern 31 which is opposite to the unevenness of the inner surface 7b of the inner case body 2b can be formed on the surface of the molded product 5b filled and solidified in the molding container 10b.

"Effects of the Present Invention" As is clear from the above explanation, the present invention has the following effects.

(1) Even if it is a relatively long and tapered molding container for molding the external shape of conventional lipsticks, etc., the inside surface can be easily cleaned, so the molding container can be used repeatedly. can.

(2) According to (1) above, the molding container does not become disposable, which is economical and saves resources.
