Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to an applicator for applying powdered cosmetics to a cosmetic buff 41 and a method for manufacturing the same.

BACKGROUND ART Conventionally, long-pile textiles, foam edge-flocked sheets, and the like have been frequently used as m-cloth base materials for powdered cosmetics.

Inside these m-fabric base materials, as a core material, a porous material such as rubber foam or non-woven fabric is used to provide elasticity and prevent settling during use. It is formed in a shape or arrangement.

11 for the manufacturing method of these conventional puffs! The edges of two sheets are sewn in advance by overlapping the movable cloth surface and the 5-pieces punched into the desired shape, leaving some unsewn parts. Insert the core, m

1M) L, I guess it's normal.

Therefore, in the conventional puff of this panicle, there is no graded part between the m-only base material and the core body, and the core body is surrounded by the buff base material circle.

As for the 5-year-old puff, after using it for k days, the inner core moves to one side, and the puff feels uneven during application, which tends to deteriorate usability.

In addition, the condition of the puff after washing may cause the above-mentioned phenomenon, making it unusable.

The present invention has been developed in consideration of these problems, and one of its main points is to ensure that the position of the center body within the puff does not change even under normal use conditions (and always maintains a good position). Usage Conditions - A type of makeup that can be maintained for a long period of time and does not cause any change in the core even after washing the puff, eliminating the problems of conventional puffs of this type. An object of the present invention is to provide a puff for use and a method for manufacturing the same.

The characteristics of the present invention based on the above-mentioned objective are that an adhesive layer is provided on the puff core base material surface made of a porous material, and a resin particle layer having K11ll properties is provided on the surface of the adhesive layer. It is a cosmetic puff that is included in the body S, and the special feature of its manufacturing method is that the adhesive is applied to the narrow surface of the puff core base material made of a porous material, and the above-mentioned I# having adhesive properties on the surface of the adhesive 41 of the core obtained in the -th step
a second step in which fat powder particles are spread and then fixed; a third step in which the core obtained in the second step is internally encapsulated in a coating material to form a puff body; This process consists of a fourth step in which the puff body obtained in the step is heated and then pressurized a11.

At this time, the fourth step also includes permeation of an organic solvent with a tin salt.

Initially, the inventor attempted to solve the problem by using a liquid adhesive between the base material and the core to secure the T-joint between the buff base material and the core, but both the core and base material were porous. Because the material is made of high quality material, the adhesive penetrates into the material, making it impossible to obtain a thick film and making it impossible to measure whether the bond is good or not. When the amount of adhesive is further increased, the adhesive oozes out on one side of the ik cloth, which is the coating base material.
Otherwise, it would partially solidify and lose its function as an applicator.

It was revealed that it is difficult to bond porous materials with ordinary adhesives.

In addition, in the trial production of the pressure-sensitive type adhesive Y core body KIIJit, we checked whether there was any oozing phenomenon of the adhesive or not, and the 111iIIIy! l
- After sewing, turn it inside out (seams are placed in the circle sK position)
When doing this, when a small piece of the unsewn part slips through, the inner core may peel off, or the one-pressure adhesive on the inner core may adhere to the fabric surfaces. It turned into a dango-like shape, and I couldn't do anything but pray for the effect.

In this case, the Department of IPI has kept both pieces of wood free until inserting the core material Y into the coated base material, and modified the core material so that it is located in the center of the puff base material. We found out that it is a good idea to fix the buff base material and the core by V-joining after shaping the material into a puff shape.

Refreshingly, the adhesive layer for consistent bonding is a thin film of adhesive 11.
This is difficult to do with Ii cloth, but synthetic 411111I powder, which can partially shape the thickness and have a fast joining assimilation speed, is optimal for joining the porous core and the m fabric base material. There was found.

These powder particles can be melted very easily by hot air or organic solvent permeation at a cost of 70 yen! : It was also found that it has an adhesive effect.

The present invention has been made through the above steps.

To explain the present invention based on Figure WnK, #! As shown in Figure 1, the puff core base material l is foamed urethane.

Q of foam rubber, etc. RA1 is an elastic porous material such as foam wood or non-woven fabric material. These core base materials 1 are punched into an elliptical shape.

It can be processed into desired shapes such as squares.

Table 1iIK of core material I completed after 5K
Polyamide-based 'I/114! #I: Apply an adhesive such as acrylic resin, urethane resin, polyester resin, polyolefin resin, or rubber adhesive. At this time, the state 1 of the adhesive layer 2 should be kept in an undried state.The adhesive layer 2 may be applied by a spray method, a zero-coat method, a dipping method, etc. Tackiness v1 without drying!
In the form 11, a composite IIL resin powder J having a high adhesion to the IllI surface Km is sprayed onto the sensitive layer. Combined **m powder grains -
J is boryamide thread resin.

Acrylic resins, polyester-based resins, and polyolein-based resins are suitable, as long as their powders have hot-melt properties or can be dissolved in organic solvents.

The synthetic resin powder layer J formed on the surface of the adhesive jI-2 becomes fixed to the adhesive layer 1 by heat treatment or natural standing conditions.

Next, the core obtained in the above step is used as a coating material, such as a fiber-knitted fabric, a foam, or a flocked sheet on the surface of the foam.

The process of incorporating the core into the m-cloth is similar to the conventional process, and after overlapping the two sides of the m-cloth of the coated material punched into an arbitrary shape, the edges are sewn. Or fusion welding IN! At this time, some parts are unjoined 11t'lL-
After adding the core to the m fabric sheet,
When the coating material is turned over (1), the coating sj on the base II of the Ik cloth material becomes exposed. After correcting the position of the core inside the fabric, the mouth part is closed and finished into a puff shape. After finishing it in a puff shape, hot air is then sent from the surface of the application part j into the inside, and the temperature of the hot air is as low as mold.
Conditions are set to melt the surface of the synthetic resin powder without changing rv.

Next, in the state Iil in which the surface of the resin powder J fixed on the adhesive layer is melted, pressure treatment is performed from the soil part t11, and by pressure treatment for 5 degrees and several seconds, the coating material base IB# is formed. The core is completely bonded and fixed.

Another method for bonding and fixing is to blow vapor of Shoulder 4II solvent into the inside from the surface of the coating sj after finishing it in a puff shape. The organic solvent can be selected arbitrarily depending on the material of the coating material, the material of the core, the material of the adhesive, and the material of the resin powder or granules. The condition is that it does not give any influence.

*ii of resin powder 3 by organic solvent vapor permeation treatment 11
Once it has dissolved, apply it! This is done by applying pressure from above.

As described above, the gist of the present invention lies in the structure of the core provided in the puff circle and the processing after finishing the puff body.

The synthetic resin powder layer provided on the surface of the core has a constant thickness t through the adhesive M, and since it is a powder, it partially forms a film with a constant thickness v when melted. Formed into a partially adhesive state, the texture of the coating material is not impaired, and there is no bonding failure due to internal penetration into the porous material at the time of adhesion, resulting in a strong bond.

What's more, since he can perform the bonding and fixing process to finish it into a puff shape, it is a highly valuable cosmetic puff that eliminates the problems of conventional products and is extremely easy to manufacture.
