Description

[0001]
[Industrial application fields]
In the present invention, a mesh container for suppressing the amount of the powder cosmetic adhering to the puff at the time of use to an appropriate amount and preventing the powder cosmetic from scattering when not in use is stretched on the inside container containing the powder cosmetic. It relates to a compact container.
[0002]
[Prior art]
In a compact container containing powder cosmetics such as powder foundation, a mesh is stretched through a frame in an inner container containing powder cosmetics, and the mesh and frame are integrated (mesh body) ) Are assembled so that they can be moved up and down while the elasticity of the elastic material is urged in the push-up direction.
[0003]
The compact container having the above-described configuration can prevent the powder cosmetic from being scattered by covering the powder cosmetic with a mesh, and can suppress the amount of the cosmetic applied to the puff to an appropriate amount. It is possible to obtain a suitable usage situation of the fee.
[0004]
In addition, the mesh body can be moved up and down with respect to the inner container, and the elastic force of the elastic material is biased in the pushing-up direction, so that the change in the stored cosmetics can be prevented from changing on the cosmetic surface. On the other hand, it is possible to always contact the mesh in a constant state, thereby making the effect of suppressing the amount of the cosmetic material adhering to the puff by the mesh constant and separating the cosmetic surface from the mesh in a non-use state. The function of the mesh is prevented from being degraded due to clogging of the mesh due to the material.
[0005]
[Problems to be solved by the invention]
However, in the above-described prior art, when the mesh body is pressed down by pressing the mesh with the puff during use, a part of the powder cosmetic is moved into the middle container and the mesh body along with the downward displacement of the mesh body. There was a problem that it squirted and scattered from between the frames.
[0006]
In order to protect the mesh, the ascending / descending displacement of the mesh body with respect to the middle container can be achieved with a weak force. Since a gap is formed between the sliding portions of the mesh body, a part of the powder cosmetics is generated as the mesh body is pushed down from the gap between the sliding surfaces of the inner container and the mesh body. Will erupt.
[0007]
As a means for closing the gap between the inner container and the mesh body while maintaining the state in which the mesh body can be moved up and down with respect to the inner container, a packing made of an elastic material such as an O-ring is provided on the outer peripheral surface of the mesh body. Although a means for providing a body is conceivable, if a packing body molded in a fixed shape in advance is assembled to the mesh body, a molding dimensional error that always occurs in the synthetic resin inner container and the mesh body frame is caused. Therefore, it is impossible to regulate the sliding resistance of the mesh body with respect to the middle container to a desired value or less.In addition, the use of a dedicated packing body complicates the structure of the compact container and makes its assembly and manufacture difficult. In addition to being troublesome, it is necessary to manufacture various types of packing bodies having different dimensions and shapes in advance, which causes a problem of increasing the manufacturing cost of the compact container.
[0008]
Therefore, the present invention was devised to solve the above-described problems in the prior art, and the sliding between the middle container and the mesh body is reduced in a state where the sliding resistance force between the middle container and the mesh body is reduced. It is a technical problem to block the gaps between the moving surfaces, and the purpose is to suppress the occurrence of a part of the powder cosmetic during use as small as possible.
[0009]
[Means for Solving the Problems]
Of the present invention for solving the above technical problem, the invention according to claim 1 is:
Having a bottomed short cylindrical container body,
Having a lid attached to the container body so as to be freely opened and closed by hinges;
Having an inner container with a bottomed short cylinder shape that is assembled in the container body and stores powder cosmetics;
In close contact with the inner peripheral surface of the inner wall of the inner container with the intimate coating film made of foam paint applied and molded on the outer peripheral surface, and the elasticity of the elastic material built in the inner container is pushed in the upward direction. Having a mesh body in which a mesh that allows powder cosmetics to pass is stretched on a frame that is assembled to be freely movable up and down,
It is in.
[0010]
According to the second aspect of the present invention, in addition to the first aspect of the invention, the upper end of the peripheral wall of the inner container is assembled with a locking frame having an inner flange piece around which the upper surface of the mesh body is locked on the lower surface. A packing body made of foamed resin, in which the upper end of the inner peripheral edge of the inner collar piece of the locking frame is in close contact with the lower surface of the locking frame, is fixed to the lower surface of the frame.
[0011]
Invention of Claim 3 is the structure which shape | molded the packing body of invention of Claim 2 with the foamed polyethylene resin.
[0012]
[Action]
With the lid open, the mesh body descends with respect to the middle container due to the pressing force of the puff when the puff is pressed against the mesh and the powder cosmetic contained in the middle container is attached to the puff. The inner peripheral surface of the inner container and the tight coating film provided on the outer peripheral surface of the frame of the mesh body are in close sliding contact with each other, so that the inner peripheral surface of the inner wall of the inner container and the outer peripheral surface of the mesh body Since there is no gap between them, a part of the powder cosmetic is ejected from the space between the inner peripheral surface of the inner wall of the inner container and the outer peripheral surface of the mesh body along with the downward displacement of the mesh body. Never do.
[0013]
The close contact coating provided on the outer peripheral surface of the frame body of the mesh body is applied and molded with foamed paint, so when the mesh body is inserted and assembled into the inner container, it is pressed against the inner peripheral surface of the peripheral wall of the inner container. The surface portion easily collapses its foamed shape by the applied pressing force and deforms into a shape that follows the inner peripheral surface of the peripheral wall of the middle container.
[0014]
For this reason, the intimate coating film formed on the outer peripheral surface of the frame body of the mesh body is in a state in which the outer peripheral surface is in close contact with the inner peripheral surface of the peripheral wall of the inner container with almost no pressure contact. The inner wall of the peripheral wall is in close contact with almost no gap.
[0015]
Attach the locking frame having the inner flange piece to the upper end of the middle container, and provide the lid with a foamed resin packing body so that the inner edge of the inner frame piece of the locking frame bites into the packing body in the closed state. Therefore, the sealing of the middle container in the closed state is achieved directly by the packing body, and the sealing of the middle container by this packing body bites the packing body at the upper edge of the inner peripheral edge of the inner frame piece of the locking frame. Is achieved very powerfully and reliably.
[0016]
【Example】
One embodiment of the present invention is shown in FIGS.
The container body 1 has a substantially cylindrical shape with a bottom and a short bottom, and is assembled with a lid 12 having substantially the same shape by hinge coupling so that it can be freely opened and closed. It is divided into three middle container assembly parts and a puff assembly part as a material storage container.
[0017]
The middle container 3 for storing the powder cosmetic has a simple bottomed short cylindrical shape that is detachably assembled in the middle container assembly part partitioned and formed in the container body 1 by the middle frame 2. On the upper end surface of the peripheral wall 4, a locking frame 10 having an inner flange piece 11 is fixed tightly.
[0018]
The mesh body 5 has a mesh 8 stretched and fixed to an upper end portion of a ring-shaped frame body 6 that is fitted into the peripheral wall 4 of the inner container 3 in a close-packed manner. The coating film 7 is directly applied and foamed.
[0019]
This mesh body 5 stores powder cosmetics with an elastic material 9 interposed between the bottom wall of the middle container 3 and the frame body 6 prior to assembly of the locking frame 10 to the middle container 2. After the mesh body 5 is inserted and assembled in the middle container 2, the locking frame 10 is firmly fixed to the upper end surface of the peripheral wall 4 of the middle container 2 and is moved up and down in the middle container 2. The mesh body 5 assembled in a freely displaceable manner is prevented from coming out of the middle container 2.
[0020]
The close-contact coating 7 is applied and foam-molded with a thickness slightly larger than the gap formed between the inner peripheral surface of the peripheral wall 4 of the inner container 2 and the outer peripheral surface of the frame body 6 of the mesh body 5. It is assumed that the outer surface portion in contact with the inner peripheral surface of the peripheral wall 4 accurately follows the inner peripheral surface of the peripheral wall 4 by the first insertion assembly process for the inner container 2.
[0021]
Therefore, even if there is some molding size error in the middle container 2 and the frame body 6, the intimate coating 7 itself is shaped so that the outer surface portion follows the inner peripheral surface of the peripheral wall 4 due to deformation of the outer surface portion. Therefore, the gap between the middle container 2 and the mesh body 5 can be almost eliminated while the sliding resistance force that is always generated is reduced.
[0022]
On the lower surface portion of the lid body 12 facing the middle container 3 assembly portion of the container body 1, the locking frame 10 has a thickness that allows light contact with the mesh 8 of the mesh body 5 that is located at the upper limit in the closed state. A packing body 13 made of a foamed polyethylene resin is fixed to a diameter that is slightly larger than the opening formed by the inner collar piece 11.
[0023]
For this reason, when the packing body 13 is in the closed state, the upper end of the inner peripheral edge of the inner flange piece 11 of the locking frame 10 bites into the peripheral edge of the packing body 13. It will be strongly and reliably intimately contacted, and thereby, the sealing of the inner container 3 in the closed state will be achieved and maintained firmly and stably.
[0024]
Further, by making the packing body 13 made of a foamed polyethylene resin, the material cost can be extremely reduced.
[0025]
【The invention's effect】
Since the present invention has the above-described configuration, the following effects can be obtained.
Since the close coating film formed by foaming paint on the outer peripheral surface of the mesh body facing the inner peripheral surface of the inner wall of the inner container is used as the sliding contact portion with respect to the inner container of the mesh body, the mesh body with respect to the inner container Can be brought into close contact with a small sliding resistance force, so that a part of the powder cosmetic is placed between the inner container and the mesh body when the mesh body is moved downward while maintaining a good mesh body up-and-down displacement operation. Can be reliably prevented from spouting and scattering.
[0026]
The intimate coating can be formed and assembled by directly applying the foam paint to the outer peripheral surface of the frame body of the mesh body, and the thickness is merely adjusting the coating thickness of the foam paint. The close contact of the intimate coating with the inner peripheral surface of the peripheral wall of the container with a small sliding resistance is accurately achieved by inserting and assembling the mesh body into the middle container. Can be easily obtained.
[0027]
The intimate coating is formed by applying foamed paint to the outer peripheral surface of the frame body of the mesh body. Therefore, the intimate coating film is always formed accurately following the shape of the outer peripheral surface of the frame body. It is easily, reliably and accurately formed without depending on the shape of the peripheral surface.
