DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for producing a stick type cosmetic such as lipstick.

[0002]

2. Description of the Related Art Conventionally, stick type cosmetics such as lipstick have been manufactured as shown in FIGS.

[0003] First, as shown in FIG. 8, a stick type cosmetic has an inner cylinder 31 rotatably fitted in an outer cylinder 30 having a bottomed cylindrical shape, and an inner plate 32 is provided in the inner cylinder 31. ing. The inner plate 32 moves up and down when the inner tube 31 is rotated relative to the outer tube 30 so as to be twisted.

[0004] Cosmetics are fixed to the inner plate 32 so as to be able to come and go from the upper edge of the inner cylinder 31 having a slope of approximately 45 degrees. When filling the stick type cosmetic with the cosmetic, if the cosmetic is filled in the upright state shown in FIG. 8, the cosmetic will flow out of the inclined portion.

Therefore, as shown in FIG. 9, a vinyl tube 33 is externally fitted on the upper portion of the inner cylinder 31, and FIG.
As shown in (3), by filling the cosmetics 34 up to the upper edge of the tube 33, the top of the inner cylinder 31 is filled without gaps.

Thereafter, as shown in FIG. 12, the excess cosmetic 34 is removed, and dirt on the upper portion of the inner cylinder 31 is removed to complete the filling.

[0007]

However, in the above-described conventional apparatus, the manufacturing process is complicated, and there are steps that depend on humans, such as removing excess cosmetics 34, so that the productivity is limited. is there.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and provides a method and an apparatus for producing a stick type cosmetic which has a simple production process, can be fully automated, and has excellent productivity. Technical issues.

[0009]

SUMMARY OF THE INVENTION In order to solve the above-mentioned technical problems, the present invention provides a cosmetic composition in a container having a bottomed cylindrical shape, a bottom portion being slidable and having an inclined portion at an upper edge. The following method was used in the method of producing a stick type cosmetic for filling with the composition.

[0010] That is, the container of the stick-type cosmetic preparation is inclined such that the inclined portion is horizontal and held alone, before
The inclined portion liquefied the cosmetic from the opening of the serial container
Fill so that it rises . And the cosmetic is cold
After being solidified, it is exposed from the opening of the cosmetic.
By heating the surface of the cosmetic that is
The surface of the cosmetic is smoothed to substantially match the inclined portion .

Further, in order to solve the above-mentioned technical problem, the present invention provides a stick for filling a cosmetic into a container having a bottomed cylindrical shape, a bottom portion being slidable and having an inclined portion at an upper edge. The following configuration was used in the apparatus for manufacturing a cosmetic.

Namely, the inclination and the holding base formed with retaining holes, said cosmetic liquefied from the opening of the container held by the holding base for holding solely by tilting the container
A filling section for filling so as to rise from the oblique section, and the container
After the cosmetics inside are cooled and solidified, the
A stick type cosmetic manufacturing apparatus comprising: a heating unit for heating the surface of the cosmetic being discharged; and a transfer unit for sequentially transferring the holding base to the filling unit and the heating unit .

[0013]

The stick type cosmetic container is inserted and held in the holding hole formed by tilting the holding base.

At this time, the container is held so that the inclined portion is horizontal. Then, the liquefied cosmetic is filled from the opening of the container so as to rise to the surface of the opening. Thereafter, the cosmetic is cooled and, if necessary, the surface of the cosmetic is heated to smooth it. Thus, the liquid level of the cosmetic is located on the same line as the inclined portion of the container.

[0015]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIGS. The container 1 has a tubular shape, and has an upper edge 3 formed with a cutout of about 45 degrees. Meanwhile, container 1
A rotary knob 1a is provided on the lower edge of the rotary knob. By rotating the rotary knob 1a, the inner plate 2 provided in the container 1 moves up and down. Note that the inner plate 2 is located at the bottom dead center when the cosmetic is filled.

The container 1 is held on a holding base 6 via a jig 6a.
Independently supported by The jig 6a has a tubular shape, and O-rings 6b and 6c are provided on its inner surface and outer surface, respectively. On the other hand, the holding base 6 has a cylindrical shape, a through hole 6d is formed at the center thereof, and the holding hole 5 is formed at an upper surface thereof at an angle of about 45 degrees.

The holding hole 5 is set to be slightly larger than the outer diameter of the jig 6a, and the jig 6a is fitted in the holding hole 5 by the elastic force of the O-ring 6c provided on the outer surface. It has become.

The container 1 is fixed so as not to rotate in the jig 6a by the O-ring 6b.
Thereby, the container 1 is held in the holding base 6 at an angle of about 45 degrees. Holding base 6 is configured is adapted to be supported in fitted into the hole provided in the transfer unit 9 barrels turntable, the following processing while rotating is performed.

The container 1 is placed on the rotation track of the holding base 6.
And a filling section 7 for filling the cosmetic 4 with the cosmetic 4
And a heating unit 8 for heating the surface of the substrate. Further, a cooling unit (not shown) is provided on a side surface of the heating unit 8.

Hereinafter, the manufacturing method will be described with reference to FIGS. The stick type cosmetic container 1 is inserted into the holding hole 5 of the holding base 6 and held. At this time, the container 1 is appropriately rotated to adjust the inclined portion of the container upper edge 3 to be horizontal.

When the container 1 reaches just below the filling section 7, the cosmetic 4 liquefied by heating or the like is poured into the container 1. If the cosmetic 4 slightly exceeds the same line as the inclined portion of the upper edge 3 of the container, the injection is stopped, and then solidified by cooling or forced air cooling (FIG. 5).

This is for overfilling the volume of the cosmetic 4 contracting by cooling to such an extent as to be maintained by the surface tension of the cosmetic, thereby coping with the volume reduction in the cooling step. Subsequently, when the transfer unit 9 rotates, the container 1 reaches the heating unit 8 as shown in FIG. 6, and the surface of the cosmetic 4 is softened and smoothed by hot air from the heating unit 8. In the smoothing step, heating and cooling may be repeated a plurality of times in accordance with the physical properties of the cosmetic 4.

As a result, the raised portion of the liquid surface of the cosmetic 4 gradually fills the hole due to the decrease in volume at the central portion .
As shown in (2), it is located on substantially the same line as the inclined portion of the container 1.

[0024]

According to the present invention, the stick type cosmetic container is held with the inclined portion being inclined so as to be horizontal, and the liquefied cosmetic is filled from the opening of the container. Can be simplified, and since there is no need for the trouble of removing excess cosmetics as in the related art, productivity and economic efficiency can be greatly improved. Also, keep the container alone
So, for example, it is possible to change the type of cosmetics for each container
In this case, in each case the temperature according to the cosmetics in each container
Can be heated in different degrees, so the cosmetic surface of each container
Can be made substantially the same as the inclined portion at the upper edge. Furthermore, excess cosmetic is not wasted and economical.
