[Background Art]
[0003] In general, women perform makeup by using cosmetic products to make their faces look
bright and beautiful.
[0004] The cosmetic products are classified into basic cosmetics, makeup cosmetics, functional
cosmetics, hair cosmetics and the like according to a function of the cosmetic products.
In addition, the cosmetic products are classified into powder, liquid, gel, and solid
cosmetic products according to a state of the cosmetic products, and stored in a container
suitable for each state of the cosmetic products.
[0005] The makeup cosmetics are classified into a base makeup used for uniformly toning
the skin and covering a defect on the skin and a point makeup for partially increasing
a three-dimensional effect on lips, eyes, nails and the like, in which the base makeup
includes a makeup base, a foundation, a powder and the like, and the point makeup
includes a lipstick, an eyeliner, a mascara and the like.
[0006] The powder in the makeup cosmetics is a powder color cosmetics, which is used mainly
to give a color effect to the skin and conceal the skin from being greasy due to defects
of the skin, sweat or oil components, while making the skin dry and soft.
[0007] The powder is applied to a face by using a puff or a makeup brush to spread the powder
uniformly on the face without sticking to hands. Therefore, in general, a powder container
for containing the powder is provided therein with a puff or a cosmetic brush in use.
[0008] In such a conventional powder container, an intermediate cap formed with a mesh is
provided inside the powder container in order to fix a puff and apply powder stored
in the powder container. When a makeup is performed, the mesh formed in the intermediate
cap is pressed by the puff such that the powder sticks to the puff.
[0009] The conventional powder container is disclosed in Korean Patent No.
10-1138661 entitled "powder container for makeup". As shown in FIG. 1, the conventional powder
container includes an intermediate cap (1) having a powder lid (2), a mesh (3) formed
of a flexible material, and a ring-shaped mesh frame (4) for fixing the mesh (3) to
a bottom surface of the powder lid (2).
[0010] In the conventional powder container, the mesh (3) formed of the flexible material
and the mesh frame (4) are ultrasonic welded together and edges of the welded mesh
(3) are cut according to the size of the mesh frame (4). Then, the mesh frame (4)
to which the mesh (3) is ultrasonic welded is placed in a mold and the powder lid
(2) is injection-molded through an insert injection molding, so that the intermediate
cap (1) is manufactured and assembled.
[0011] However, according to the conventional powder container, the intermediate cap (1)
is manufactured through the steps of welding the mesh (3) with the mesh frame (4),
cutting the mesh (3), placing the mesh frame (4) in the mold and injection-molding
the powder lid (2), so that the manufacturing process is complicated and the work
space and a lot of workers are required, thereby remarkably lowering the productivity
and increasing the manufacturing cost.
[0012] In order to solve the above-mentioned problems, Korean Patent No.
10-1248345 discloses "intermediate cap of cosmetic powder container and manufacturing method
thereof". According to the above related art, as shown in FIG. 2, an intermediate
cap mounted in a cosmetic powder container includes a powder lid (5), a mesh 6 and
a mesh frame (7) for forcibly fixing the mesh (6) to the powder lid (5). In addition,
a fixing protrusion (5a) and a pressing wedge (5b) circumferentially protrude from
the powder lid (5) for primarily and secondarily fixing and pressing the mesh (6)
when the mesh (6) is assembled with the powder lid (5), and the mesh frame (7) is
formed with annular grooves (7a) and (7b) into which the fixing protrusion (5a) and
the pressing wedge (5b) are fitted.
[0013] However, according to the above related art, when the powder lid (5) is coupled in
a state in which the mesh (6) is placed on the mesh frame (7), the mesh (6) may be
pushed in one direction depending on the degree of friction between the mesh frame
(7) and the powder lid (5), so that the intermediate cap may be assembled poorly or
one side of the mesh (6) of the intermediate cap may be decoupled between the mesh
frame (7) and the powder lead 5 during use.

of the present invention.
[0057] As shown in FIG. 8, the present invention includes the steps of: preparing the cap
body (30), the coupling ring (40), the mesh (50) and the lower cover (60) constituting
the intermediate cap (20) of the powder container (10) (S100); reversely turning over
the cap body (30) (S200); placing the mesh (50) on an upper portion of the coupling
wheel (32) of the cap body (30) fixing the mesh (50) by forcibly fitting the coupling
ring (40) around the coupling wheel (32) of cap body (30) (S400); and coupling the
lower cover (60) to the cap body (30) while wrapping the coupling ring (40) and the
mesh (50) (S500).
[0058] As shown in FIG. 7b, in step (S300) of placing the mesh (50) on an upper portion
of the coupling wheel (32) of the cap body (30), the mesh (50) may have a diameter
larger than a diameter of the coupling wheel (32) such that the mesh (50) may completely
cover the upper portion of the coupling wheel (32).
[0059] As shown in FIG. 7c, in step (S400) of fixing the mesh (50) by forcibly fitting the
coupling ring (40) around the coupling wheel (32) of the cap body (30), the first
coupling protrusion (322) of the coupling wheel (32) and the second coupling protrusion
(42) of the coupling ring (40) are forcibly coupled with each other so that the mesh
(50) in tightly pulled outwardAs shown in FIG. 7d, in step (S500) of coupling the
lower cover (60) to the cap body (30) while wrapping the coupling ring (40) and the
mesh (50), the first coupling protrusion (36) of the cap body (30) is coupled with
the second coupling protrusion (642) of the lower cover (60) and the pressing portion
(62) of the lower cover (60) presses the mesh (50) from the bottom of the mesh (50)
so that the mesh (50) comes in close contact with the lower surface of the cap body
(30).
[0060] At the same time, as shown in FIG. 7e, the first toothed protrusion (624) of the
pressing portion (62) is engaged with the second toothed protrusion (324) of the cap
body (30) so that the mesh (50) is more firmly and tightly pulled.
[0061] A method of using the intermediate cap of the powder container to which the mesh
is assembled by the coupling ring and the lower cover will be described below.
[0062] In order to use the intermediate cap of the powder container to which the mesh is
coupled by the coupling ring and the lower cover according to the present invention,
the container lid (14) is decoupled from the container body (12). Then, as shown in
FIG. 6, the user holds the puff (P) seated on an upper portion of the intermediate
cap lid (70) and the intermediate cap lid (70) is opened.
[0063] After that, the upper surface of the mesh (50) fixedly coupled between the cap body
(30) and the coupling ring (40) is pressed by the puff (P), so that the mesh (50)
having flexibility is elastically pressed downward against the container body (12).
