Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a cosmetic puff and a method for manufacturing the same.

[Prior Art and Problems to be Solved by the Invention] Cosmetic puffs have been known that have a three-layer vertical cross-section, in which a pile fabric is used as an outer cover and a flat cushion material is housed in the outer cover. There is. To manufacture such a cosmetic puff, cut the pile fabric into an appropriate size, place the two cut pieces together with their raised sides together, and wrap the circumference of the cut piece until it becomes impossible to turn it over. After sewing, the fabric is turned inside out to expose the raised side, a soft sponge or other cushioning material is inserted into the fabric, and the unstitched portion is hand-stitched to create a product.

Cosmetic puffs manufactured in this manner require considerable effort and have poor productivity, and although they are consumables, they are considerably expensive. Additionally, this hand-sewn part may fray when washed. Furthermore, since the pile fabric and the cushion material are not bonded, repeated washing with water may cause the pile fabric to stretch and lift off the cushion material, resulting in unevenness on the surface of the puff.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a cosmetic puff that does not fray or cause unevenness on the surface of the puff even after repeated washing, and an easy method for manufacturing the same.

[Means for Solving the Problems] The cosmetic puff of the present invention has an outer cover made of pile fabric of heat-fusible fibers, and a flat cushion material having heat-fusible properties is housed in the outer cover. The cosmetic puff has a three-layer structure in vertical section, and one surface of the cushion material is adhered to the pile fabric over the entire surface, and the other surface has a slight adhesive bond between the pile fabric and the entire surface. The three layers are thermally fused together at the periphery of the puff (Claim 1).

This cosmetic puff manufacturing method involves bonding a heat-fusible fiber pile fabric to a heat-fusible sheet-like cushion material, and then overlaying the heat-fusible fiber pile fabric on the cushion material side. The three-layer structure is cut into a predetermined shape and fused using a high-frequency welder or an ultrasonic welder (claim 2).

Another cosmetic puff of the present invention has an outer cover made of heat-fusible fiber pile fabric and heat-fusible synthetic leather,
A cosmetic puff containing a heat-sealable flat cushion material in the outer jacket, the vertical cross section of which has three layers: the pile fabric layer, the cushion material layer, and the synthetic leather layer, One surface of the cushion material is bonded to the pile fabric over the entire surface, and the other surface has a slight gap between the cushion material and the synthetic leather, and the three layers are integrated at the peripheral edge of the puff. (Claim 3).

The manufacturing method for this cosmetic puff involves bonding a heat-fusible fiber pile fabric to a heat-fusible sheet-like cushion material, and then layering heat-fusible synthetic leather on the cushion material side. It is characterized in that it has three layers, and this three-layer structure is cut into a predetermined shape and fused using a high frequency welder or an ultrasonic welder (claim 4).

Another cosmetic puff of the present invention has an outer cover made of pile fabric of heat-fusible fibers, and has two layers of heat-fusible flat cushion material housed in the outer cover, and has a vertical cross section of four. A cosmetic puff with a layered structure, wherein the two layers of cushion material are bonded to the pile fabric on the outer surface thereof over the entire surface, and there is a gap between the two layers of cushion material over the entire surface,
The four layers are integrally heat-sealed at the periphery of the puff (claim 5).

This method of manufacturing a cosmetic puff involves bonding a heat-fusible fiber pile fabric and a heat-fusible sheet-like cushion material to form two layers, and forming this two-layer structure so that the cushion materials face each other. The method is characterized in that four layers are formed by stacking them so that they fit together, and the four-layer structure is cut into a predetermined shape and heat-fused using a high-frequency welder or an ultrasonic welder (claim 6).

[Function] The cosmetic puff of the present invention has a multilayer structure made of a heat-sealing material, and since the periphery of the puff is heat-sealed together, the periphery of the puff will not fray.

In addition, since one side of the cushion material is glued to the pile fabric, not only does the cushion material not move inside the puff while it is in use, but even after repeated washing, the pile fabric stretches and the cushion material It will not lift up and cause unevenness on the surface of the puff.

On the other hand, on the other side of the cushion material, there is a gap across the entire surface between it and other pile fabrics, synthetic leather, or other cushion materials, so the elasticity of the entire puff is increased. .

The cosmetic puff of the present invention can be easily manufactured by cutting and fusing a multilayered structure made of a heat-sealable material into a predetermined shape using a high-frequency welder or an ultrasonic welder.

[Example] In Fig. 1 and Fig. 2, 12 and 14
is an outer cover made of pile fabric whose warp and weft are made of heat-fusible fibers, and a flat heat-fusible cushion material 16 is accommodated in this outer cover. Upper pile fabric 12 and cushion material 1
6 is bonded over the entire surface with an adhesive 18, but a slight gap 20 is provided between the lower pile fabric 14 and the cushion material 16 over the entire surface. The three layers of the upper pile fabric 12, the cushion material 16, and the lower pile fabric 14 are heat-sealed together at the peripheral edge 22 of the puff.

The pile fabrics 12 and 14 are made of cut pile, and the length of the pile in this example is 5 mm. The heat-fusible fibers forming this pile fabric are preferably heat-fusible synthetic fibers such as nylon, polyester, and acrylic. In particular, polyester fibers are preferred. The upper pile fabric 12 and the lower pile fabric 14 may be of the same type or different types.

The cushion material 16 is preferably a nonwoven fabric made of heat-fusible fibers, a polyurethane sponge, or the like. In this example, a polyurethane sponge with a thickness of 8 mm is used.

The adhesive 18 for bonding the upper pile fabric 12 and the cushion material 16 is preferably an adhesive that does not lose its flexibility even after hardening, and in this embodiment, a rubber-based soft adhesive is used.

The upper pile fabric 12 and the cushion material 16 need only be bonded over the entire surface, or may be dotted with adhesive over the entire surface.

To manufacture the cosmetic puff of this example, as shown in FIG. The polyurethane sponge 16 is placed on the bottom side to form three layers. A high frequency welder or an ultrasonic welder (not shown) equipped with a circular metal chisel having a diameter of 8 cm is operated on the three-layer structure 24 for 1 to 3 seconds to cut and fuse the three-layer structure 24 into a circular shape. That is, since there is a difference in melting temperature between the pile fabrics 12 and 14 and the polyurethane sponge 16,
The melted portion of the polyurethane sponge 16 flows into the space in the fabric structure of the pile fabrics 12, 14, and the three layers 12, 16, 14 are completely fused,
They are simultaneously cut by the teeth of a metal chisel. In addition,
Since the melted and fused polyurethane softens the fused portion, the peripheral edge 22 of the puff does not have a rugged, unnatural feel.

Further, by fluffing the pile fabric near the peripheral edge 22 with a brush or the like, the fused portion becomes less noticeable.

FIG. 4 shows another embodiment in which the lower jacket is made of heat-sealable synthetic leather 26. By forming one side of the outer cover with synthetic leather 26 in this way, the puff can be given a waist,
It feels good to the touch and has a luxurious feel. Further, a pattern, a company name, etc. can be engraved on this synthetic leather 26.

Note that heat-fusible synthetic leather includes not only cases where the synthetic leather itself is made of a material that has heat-fusibility, but also cases where one side of the synthetic leather (such as polyurethane sponge) is not made of such a material. 1
This also includes a case in which a heat-fusible adhesive is applied to the surface (side surface 6) so that the entire surface has heat-fusible properties.

In order to manufacture the cosmetic puff shown in FIG.
As shown in the figure, a pile fabric 12 and a polyurethane sponge 16 are bonded together with a soft adhesive, and this two-layer structure is stacked on a heat-adhesive synthetic leather 26 with the polyurethane sponge 16 facing downward. There are three layers. This three-layer structure 28 is cut into a predetermined shape and fused by a high frequency welder or an ultrasonic welder (not shown) equipped with a metal chisel.

FIG. 6 shows yet another embodiment, in which two layers of polyurethane sponges 16 and 17 are housed in an outer jacket made of pile fabrics 12 and 14. The polyurethane sponges 16 and 17 are adhered to the pile fabrics 12 and 14, respectively, over the entire surface, but a gap 20 is provided between the polyurethane sponge 16 and the polyurethane sponge 17 over the entire surface. This gap 20 is different from the previous two embodiments (second embodiment), especially in its center.
(see Fig. 4).

The cosmetic puff of this example has two layers of polyurethane sponges, and the gap between the polyurethane sponges is large, making it highly elastic and comfortable to the touch. .

In order to manufacture the cosmetic puff shown in FIG.
As shown in the figure, pile fabric 12 and polyurethane sponge 16 are bonded together using a soft adhesive, and pile fabric 14 and polyurethane sponge 17 are bonded together.
are bonded with a soft adhesive to prepare two-layer structures 30 and 32, respectively, and these two-layer structures 30,
32 is stacked with polyurethane sponges 16 and 17 facing each other to form four layers. This four-layer structure 3
4 is cut into a predetermined shape and fused by a high frequency welder or an ultrasonic welder (not shown) equipped with a metal chisel.

[Effects of the Invention] As described above, the cosmetic puff of the present invention has a multi-layer structure made of heat-adhesive materials, and since the periphery of the puff is heat-sealed together, it is durable even after repeated washing. The edges of the puff will not fray.

In addition, since one side of the cushion material is bonded to the pile fabric of the outer covering, the puff not only has an appropriate stiffness as a cosmetic puff, but the cushion material does not move inside the puff while it is in use. Furthermore, even after repeated washing with water, the pile fabric does not stretch and lift from the cushion material, causing unevenness on the surface of the puff, unlike in the past.

In addition, the cushion material may be made of other pile fabric (Claim 1) or synthetic leather (Claim 3) on the other side.
Alternatively, since there is a gap over the entire surface between the puff and other cushion materials (claim 5), the entire puff has great elasticity and feels good to the touch.

The method for producing a cosmetic puff of the present invention is a simple method in which a multilayer structure made of a heat-fusible material is cut into a predetermined shape and fused using a high-frequency welder or an ultrasonic welder. Therefore,
Compared to conventional manufacturing methods, the number of work steps can be significantly reduced and productivity is extremely high, so costs can be significantly reduced.
