TECHNICAL FIELD OF THE INVENTION
The present invention relates to a powder compact in which a mesh is stretched at the mouth of an inner plate for accommodating cosmetic powder.
[0002]
[Prior art]
BACKGROUND ART Conventionally, there is a powder compact inner plate with a mesh as shown in FIG. 7 which is a container for accommodating cosmetic powder.
[0003]
The annular frame 1 fitted to the inner plate 20 shown in FIG. 7 is provided with an inward flange 2 and a downwardly hanging tubular portion 6 on the annular frame 1 made of synthetic resin. The peripheral edge of the mesh fabric 13 is fixed to the upper surface 5 of the inward flange 2 of the body 1, and the mesh fabric 13 is stretched over the annular frame 1.
[0004]
The mesh fabric 13 is generally fixed to the annular frame 1 by inserting the mesh fabric 13 into a mold for molding the annular frame 1 and injecting a molten resin into the inserted mold. The annular frame 1 on which the mesh fabric 13 is stretched is formed.
[0005]
Then, after accommodating powder for makeup, the inner plate 20 is fitted with the annular frame 1 in which the mesh fabric 13 is fixed to the upper surface 5 at the mouth of the inner plate 20, as shown in FIG. The annular frame 1 is fitted outside the cylindrical projection 21 at the mouth of the inner plate 20.
[0006]
The inner plate 20 containing the powder is stored in a powder compact (not shown) for use.
[0007]
[Problems to be solved by the invention]
The inner plate 20 containing the powder is used for makeup by pressing the puff from the upper surface of the mesh fabric through the mesh fabric 13 to the powder to attach the powder to the puff.
[0008]
Then, at the peripheral edge of the mesh fabric 13, the portion adhered to the upper surface portion 5 of the inward flange 2 of the annular frame 1 is attached to the upper surface portion 5 of the inward flange 2 every time the puff is pressed against the mesh fabric 13. On the other hand, it is pulled inward.
[0009]
Then, the periphery of the mesh fabric 13 fixed to the upper surface 5 of the inward flange 2 is partially peeled off from the upper surface 5.
Since the thread forming the mesh fabric 13 is formed by twisting fibers, when the mesh fabric 13 is fixed to the annular frame 1, an adhesive or an annular frame during insert molding is used. The molten resin for forming the mesh fabric 1 penetrates between the twisted fibers of the yarn pieces forming the mesh fabric 13, and fixes the mesh fabric 13 to the annular frame 1.
[0010]
Therefore, as described above, when the peripheral portion of the mesh fabric 13 is peeled off from the upper surface portion 5 of the inward flange 2, the adhesive or the annular frame 1 that has infiltrated between the fibers of the thread pieces can be used. Small pieces of resin that have fixed the mesh fabric 13 to the annular frame body 1 are separated from the thread pieces and adhere to the mouth of the inner plate 20, or penetrate into the powder of the cosmetic. This stains the mouth of the plate 20 and the powder of the cosmetic.
[0011]
SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has as its object to prevent the mesh fabric attached to the powder compact's inner plate from peeling off, thereby preventing the mouth portion and powder of the inner plate from being stained.
[0012]
