PURPOSE:To form in soft cake-like state cosmetic material housed with the surface of the cosmetic material placed on the same surface with the middle plate by press forming the product through the bottom plate on which the surface of the filled cosmetic material is taken into a frame body having a pleated stage part on the internal periphery in a freely rising and falling state with contact friction of the external periphery. CONSTITUTION:On a pleated stage part 10 in which a bottom 1 is formed on the internal periphery of a frame body 2, a projection 1a formed on the external periphery is engaged to position in a freely rising and falling state. A frame body 2 constituting the middle plate 4 is placed on a thin paper 5 in a reversed state, and boring cosmetic material 8 is filled inside. A bottom plate 1 is placed to lightly press it with a press. The surface of the boring cosmetic material meets the upper end 2a of the frame body 2 on the same surface. When the surface penetrates into the stage part 10 and the thin paper 5 is removed, the cosmetic material becomes a soft cake-like material.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a method for manufacturing a cosmetic product in which a cosmetic is accommodated flush with the upper end surface of an inner tray.

[Prior Art] In general, cosmetic products such as foundations are
), a metal inner tray 9 is filled with powdered or clay-like cosmetics 3, and in that state, as shown in FIG. 5 is placed on the paper, pressed with a press plate 6 to harden it, and then the thin paper 5 is removed.

[Problem to be solved by the invention]

However, in this case, since the press plate 6 is used to press the cosmetic, even if the cosmetic is filled in the inner tray-cup, the cosmetic 3 will be below the upper end surface of the inner tray 9, as shown in FIG. 3(C). This gives the consumer the impression that the quantity of cosmetics is insufficient.

Moreover, since the above-mentioned phenomenon amplifies and manifests the variation in the amount of the cosmetic, a problem arises in that the upper surface of the cosmetic 3 drops significantly due to a slight lack of amount. Moreover, in the above case,
Since the cosmetic material 3 filled in the inner tray 9 is pressed and hardened and fixed to the inner tray 9, the cosmetic material becomes hard and is housed in the inner tray in the form of a so-called hard plate.

Cosmetics stored in a hard plate like this cannot be transferred unless the cosmetic puff is pressed strongly, so damage such as cracks occurs early due to strong pressure. A problem arises in that the cosmetic material breaks into small pieces and separates from the inner tray, making it impossible to use the cosmetic product to the end.

This invention was made in view of the above circumstances, and the surface of the cosmetic is flush with the upper edge of the inner tray, and the cosmetic contained therein is shaped into a soft cake. Its purpose is to provide a method for manufacturing cosmetic products.

[Means to solve the problem]

In order to achieve the above object, the method for producing a cosmetic product of the present invention includes: a frame body having a pleated step on its inner peripheral surface; a bottom plate that is attached to the frame body so as to be able to rise and fall freely by contact friction on the outer peripheral surface; a step of preparing a frame body, a step of placing the frame body on a table surface and filling the inside with a cosmetic material, and a step of press-molding the surface of the filled cosmetic material through the bottom plate. Take.

[Function] That is, the present invention provides a bottom plate that is attached to the frame so that it can be raised and lowered by the contact friction between the frame having pleated steps on the inner circumferential surface and the outer circumference, and the frame is attached to the base surface. A cosmetic product is manufactured by placing a powdered cosmetic or the like inside the container, filling it as it is or after preforming, and press-molding the surface of the cosmetic through a bottom plate. Therefore, in the cosmetic product obtained by this manufacturing method, the surface of the cosmetic and the upper end of the frame are flush with each other. Furthermore, according to the manufacturing method of the present invention, even if the amount of cosmetics varies, the bottom plate can move up and down within the frame during pressing to absorb the variations in the amount of cosmetics. It is possible to produce a cosmetic product in which the surface of the cosmetic material and the upper end of the frame are flush with each other regardless of the appearance. Further, in the cosmetic product obtained by the above-mentioned manufacturing method, the cosmetic is fixed in a state in which the outer peripheral portion of the cosmetic is bitten into the pleated step portion of the inner peripheral surface of the frame. Therefore, instead of having to forcefully press the cosmetics to make them stick to the inner tray as in the past, the cosmetics can be fixed by simply lightly pressing the cosmetics. It becomes possible to store it in a soft cake shape,
To easily remove the cosmetic with a puff or the like, and at the same time to prevent the cosmetic from falling off due to cracking.

Next, examples will be described.

[Example] A medium plate 4 as shown in FIG. 1 is prepared. This medium plate 4 is
It is composed of a substantially rectangular frame body 2 made of plastic material and a substantially rectangular bottom plate 1 that closes the bottom opening of the frame body 2.

The bottom plate 1 is positioned so as to be vertically movable by engaging a protrusion 1a formed on the outer periphery of the bottom plate 1 with a pleated step 10 formed on the inner periphery of the frame 2. On the other hand, a powdered or clay-like cosmetic is placed in a frame or the like and formed into a plate, and the plate-shaped cosmetic is formed into a substantially rectangular shape using a rectangular frame-shaped cutting machine and punched out.
make. Next, place the thin paper 5 on the top surface of the stand (not shown),
Place the frame 2 constituting the inner plate 4 upside down on the thin paper 5,
In this state, the punched cosmetic material 8 is packed inside the frame 2 as shown in FIG. 1(a). Then, put the bottom plate 1 on and
As shown in Figure (b), press the bottom surface of the bottom plate 1 onto the press plate 6.
Press lightly. As a result, the bottom plate 1 moves within the frame 2 in the downward direction (toward the upper end of the frame) as shown in the figure, and the punched cosmetic 8 is placed on the base surface of the stand as shown in FIG. 1(C). The surface thereof is flush with the upper end surface 2a of the frame 2. In this case, the side surface 8a of the punched cosmetic 8
However, due to the press pressure, the punched cosmetic material 8 enters the gap between the stepped portions 10, and the punched cosmetic material 8 is stopped from being punched out. Next, the frame 2 is turned over to the correct state, and the thin paper 5 is removed from the upper surface of the punched cosmetic 8 to obtain the intended cosmetic product.

In the cosmetic product thus obtained, the upper end of the inner tray 4 consisting of the frame 2 and the bottom plate is flush with the surface of the punched cosmetic 8. It is filled with a light press, making it soft and cake-like.

In addition, when filling the inner tray 4 similar to the above with powdered or clay-like cosmetics and hardening it, a similar one as above is placed on the base surface of the base 12 equipped with the suction hole 11 that communicates with a vacuum pump (not shown). It is also possible to place a thin paper 5 on it, fill it with cosmetics 3 as shown in FIG. 2(a), and then press and fix the cosmetics 3 while applying vacuum suction as shown in FIG. 2(b). By doing this, the cosmetic 3 is removed by the negative pressure caused by vacuum suction.
When the air contained in the cosmetic material 3 is removed, a soft and dense cosmetic material 3 can be obtained.

The cosmetic to be filled in the frame 2 is not particularly limited, and may be any of foundation, lipstick eye shadow, and blusher.

Further, in the above embodiment, the bottom plate 1 is made of plastic material, but it is not limited to this, and may be made of aluminum, iron, etc. as long as it easily comes into frictional contact with the pleated steps. There is no problem.

〔Effect of the invention〕

As described above, the present invention fills a frame with pleated steps on the inner peripheral surface with a cosmetic material as it is or is preformed, and the surface of the filled cosmetic material is rubbed by the contact friction of the outer peripheral surface. Cosmetic products are manufactured by press-molding the bottom plate attached to the frame. Therefore, it is possible to obtain a cosmetic product in which the upper end of the frame and the surface of the cosmetic are flush with each other. In addition, as it is inside the frame,
Alternatively, even if the volume of preformed and filled cosmetics varies, the bottom plate moves up and down within the frame during pressing to absorb the variations in volume, and the surface of the cosmetic and the top of the frame-shaped container However, it is possible to produce cosmetic products with a uniform appearance regardless of variations in the amount of cosmetics. Furthermore, during press molding, the outer peripheral portion of the cosmetic material is bitten into pleated steps formed on the inner peripheral surface of the frame, thereby fixing the cosmetic material. Therefore, the cosmetic can be fixed by simply pressing it lightly, without having to forcefully press the cosmetic to make it stick to the inner tray. As a result, the cosmetics are stored in a soft cake-like shape, making it easy to transfer the cosmetics by simply applying a puff or the like, and allowing the cosmetics to be used to the last without causing any cracks. Cosmetic products can be manufactured.
