Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) This invention is applicable to bar-shaped cosmetics such as lipsticks, eye shadows, etc.
In particular, the present invention relates to a mold for forming a base portion into a small diameter portion to fit into a cosmetic container.

(Prior Art) Conventionally, rod-shaped cosmetics such as lipsticks and eye shadows are molded in the molding hole of a split mold, as shown in FIGS. 14 and 15.
The rod-shaped cosmetic (3) that has been cooled and solidified in the molding hole (2) of the split mold (1) is taken out by disassembling the split mold (1), and then placed into the inner tray of the cosmetic container by hand. My brother had planted it. Therefore, manual molding and planting in containers easily scratches the outer surface of the cosmetic, and the work efficiency is poor, making it unsuitable for mass production. Therefore, after molding the bar-shaped cosmetic,
- There was a demand for automatic molding and automatic implantation of the manual implantation into the wooden tray.

Therefore, in order to meet such a demand, the present applicant has created a vent hole (4) on the upper periphery and an annular 7-run hole (as shown in FIG. 16).
5) Synthetic ILI called onobe capsule with
A short tubular synthetic (polished) upper mold (8) with an annular step (7) provided on the inner periphery of the body is fitted onto the upper part of the Itt lower mold (6), and the lower periphery kk At this point, the vent hole (4) of the lower mold (6) is connected to the inner cylinder so as to be closed.

Next, the molten cosmetic is filled into the molding hole (9) defined by the lower molding die (6) and the upper molding die (8), and after being cooled and solidified, the upper peripheral edge of the lower molding die (6) Annular 7 provided in
By pressing down the runno (5) with the press plate (10), as shown in Fig. 17, the lower mold (6) is slightly pushed down, opening the ventilation hole (4), and at the same time the inside of the lower mold (6) is pressed down. A gap (11) is formed between the bottom and the lipstick.

Next, a medium (13) supported by a container (12) is supplied into the upper mold (8) from above, and its lower peripheral edge is an annular step provided on the inner periphery of the body of the upper mold (8). As shown in Figure 18, after the pressurized air is inserted into the open vent hole (4) of the lower mold (6) as shown by the arrow in the figure.
) into the gap (11) to form a rod-shaped cosmetic (14).
We proposed a method in which the container is pressurized upward and inserted into the inner tray (13). This is Japanese Patent Application Publication No. 59-4080
It is disclosed in Publication No. 6.

(Problems to be solved by the invention) In any of the conventional known molding methods,
Molded rod-shaped cosmetics such as lipsticks and eye shadows are formed to have the same outer diameter up to the base, so when inserted into the inner tray, the outer circumferential surface of the lipstick and the cosmetic container are separated by the thickness of the inner tray. As shown in FIG. 19, a gap is formed between the inner circumferential surface and a gap occurs depending on the gap. As a result, bar-shaped cosmetics, especially Is-type cosmetics, are at risk of breakage due to cracks caused by the gaps.

Further, there was also the problem that the molten cosmetic material entered the contact point between the lower mold and the upper mold, and the beauty of the periphery of the bar-shaped cosmetic material was impaired.

A step of filling and solidifying the cosmetic material, a step of pulling out the sleeve, a step of supplying the cosmetic container into the mold, and a step of pushing down the lower capsule to open the hole inside the lower capsule. It is characterized by comprising the steps of creating a gap at the bottom, and supplying pressurized air into the gap through the vent hole to eject the bar-shaped cosmetic and implanting it in the cosmetic container.

The second invention provides a cylindrical mold body, a two-layer capsule forming a ring-shaped mold that is removably inserted into the lower part of the mold body, and a lower outer periphery of the mold body in place of the two-layer capsule. The two-layer capsule is inserted into the mold body, the first cosmetic is filled and solidified, the two-layer capsule is pulled out, and the lower capsule is inserted into the mold body. JI capsule! The second cosmetic material is then filled and solidified, and the lower capsule is pushed down slightly to open the blocked vent hole, creating a void in the inner bottom of the lower capsule, and the pressurized air flows into the void through the vent hole, causing the makeup to disappear. The bar-shaped cosmetic is ejected into a cosmetic container and is characterized by having a two-layer structure in which the first and second cosmetics are joined in the longitudinal direction.

The third invention provides a cylindrical mold body and a lower outer periphery l of the mold body.
It consists of a lower capsule with a ventilation hole that is slidably inserted into the bottom of the mold, and a sleeve that is removably inserted into the upper part of the mold body. A small diameter part corresponding to the wall thickness of the middle plate is attached to the base of the rod-shaped cosmetic, which has an inner diameter that matches the inner diameter of the inner plate and is formed to protrude inward from the inner peripheral surface of the mold body by an amount equivalent to the wall thickness of the middle plate. It is characterized by the formation of

In the fourth invention, the cylindrical part of the lower capsule is inserted into the external force of the cylindrical part of the mold main body, and only the lower surface of the lower capsule and the lower surface of the mold main body are in contact with each other, and the ventilation hole is formed so that the lower capsule is connected to the lower part of the mold main body. It is characterized in that it is inserted into the outer periphery and is closed in the L position, and is formed in a position that opens downward from the lower part of the mold body when pushed down slightly.

The fifth invention provides a cylindrical mold body, a two-layer capsule forming a shaft-shaped mold that is removably inserted into the lower part of the mold body, and a lower outer periphery of the mold body instead of the two-layer capsule.
