This application claims the benefit of Korean Application No. 10-2020-0106913 filed on Aug. 25, 2020 with the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference.
The present invention relates to a mesh fusion device for a cosmetic container, and more particularly, to a mesh fusion device for a cosmetic container, in which a mesh is inserted between the first and second fixing plates overlapping each other so that the whole mesh is pressed and fixed, and as an interval between the first and second fixing plates and the frame support unit is changed, the mesh is fused to the frame with a uniform tension over an entire area thereof, and the tension of the whole mesh is freely adjusted.
A cosmetic product refers to an article that is used for a human body in order to add the charm of the human body and change the appearance of the human body brighter by making the human body clean and beautiful, or to maintain or promote the health of the skin or hair.
According to the purpose of use, the cosmetic product is classified into face-washing cosmetics used to remove sebum, wastes, and contaminants from a skin surface, basic cosmetics used to appropriately supply moisture and oil to the skin, color cosmetics used to express beautiful colors, hair cosmetics used to protect and nourish the hair while removing foreign substances from the hair or scalp, perfumes having fragrant materials dissolved in alcohol and used to exude fragrances to other people, and the like.
As cosmetic products are developed as described above, the development of various cosmetic containers for accommodating cosmetic materials is also required.
In general, among the cosmetic products, cosmetic products that have a liquid or gel form, such as a lotion, cream, foundation, gel, shampoo, and conditioner, are stored in a container having an open top and having an open/close function, and used by taking some cosmetic products out of the container with a finger or a makeup tool such as a puff and applying the cosmetic products to the skin. Recently, in order to allow cosmetic products accommodated in a cosmetic container to be uniformly smeared onto a makeup tool, a cosmetic container including a mesh formed of an elastic material has been developed and used.
As a conventional cosmetic container as described above, Korean Utility Model Registration No. 20-0472370 has been disclosed, in which the conventional cosmetic container includes a container body in which a cosmetic product is accommodated, a middle cap coupled to an inlet portion of the container body, and an elastic mesh bonded to an inner side of the middle cap by ultrasonic fusion. When briefly reviewing a process of ultrasonically fusing the elastic mesh of the conventional cosmetic container to the middle cap as described above, an operator places the middle cap on the elastic mesh and ultrasonically fuses the elastic mesh to the middle cap by using an ultrasonic fusion device.
However, in the conventional ultrasonic fusion structure, the mesh is fused to the middle cap without being pulled taut, so that a tension of the mesh may be reduced. Accordingly, when used for a long period of time, the mesh may sag downward by a weight of the cosmetic product absorbed by the mesh, so that a function of the mesh may not be performed properly.
In order to solve the problems as described above, Korean Patent Registration No. 10-1691789 has disclosed an ultrasonic fusion apparatus for a screening net and an annular member. According to the related art, an annular member supply line, a screening net supply line, and an ultrasonic fusion device are provided in one work table so as to increase productivity, and an annular member support piece ascends higher than a net flange when the annular member is fused to the screening net by the ultrasonic fusion device so that the screening net may be fused to the annular member in a taut state.
However, since the related art has a structure in which the annular member support piece provided in the ultrasonic fusion device ascends by an ascending/descending actuator to ascend higher than a height of the net flange by a predetermined height while supporting the screening net and the annular member from bottoms thereof so that the screening net is maintained taut only at a portion between a start point of a screening net winding roll and an end point of a driving roller provided in a withdrawal driving unit, when the screening net is fused to the annular member, the screening net may not have a uniform tension over the whole edge of the screening net, and a magnitude of the tension of the screening net fused to the annular member may not be freely adjusted according to a container structure to which the screening net is applied or a type of a cosmetic product in which the screening net is used.
In other words, according to the related art, in a process of expanding the screening net, the screening net is pulled taut only in one direction, that is, one direction according to both axes from the start point of the screening net winding roll to the end point of the driving roller, whereas the screening net is fused to the annular member without being pulled at all in a direction intersecting the above direction. Accordingly, when the annular member is coupled to a container for use, the screening net fused to the annular member may be wrinkled at a portion thereof having no tension as the screening net retains a cosmetic product, so that usability and an aesthetic impression of the screening net may be deteriorated.
Therefore, it is necessary to develop a mesh fusion device for a cosmetic container, in which an entire area of a screening net fused to an annular member having a ring shape expands toward an edge portion of the annular member to have a uniform tension, and the tension of the screening net may be freely adjusted according to a structure of the cosmetic container or a type of a cosmetic product stored in the cosmetic container.

Hereinafter, a mesh fusion device for a cosmetic container according to one embodiment of the present invention will be described with reference to
As shown in the drawings, according to one embodiment of the present invention, a mesh fusion device 1 for a cosmetic container refers to a device for fusing a mesh 70 to one surface of a frame 60, and may include a frame support unit 10, first and second fixing plates 20 and 30, and a fusion unit 40. In this case, the frame 60 refers to a component for fixing the mesh 70 to the cosmetic container, and may be formed in a ring shape and coupled to an open portion of the container in which a cosmetic product is accommodated. In addition, the mesh 70 refers to a fabric formed of an elastic material that is densely perforated like a net, and may be fused to the one surface of the frame 60 and elastically pressed by a user to discharge the cosmetic product through fine holes.
Hereinafter, the mesh fusion device for the cosmetic container according to one embodiment of the present invention will be described for each component.
The frame support unit 10 refers to a part on which the frame 60 is fixedly seated, and may have a three-dimensional shape having a predetermined area so that the frame 60 may be easily seated on a top surface of the frame support unit 10. Although the frame support unit 10 has been shown in the drawings of the mesh fusion device according to one embodiment of the present invention as having a rectangular parallelepiped shape, the embodiments are not limited thereto, and the frame support unit 10 may have various shapes or sizes in consideration of a work space, work efficiency, and a shape or a size of the frame.
A frame seating part 12 may protrude from the top surface of the frame support unit 10, and the frame 60 may be seated on the frame seating part 12 while covering at least a portion of the frame seating part 12. The frame seating part 12 may protrude by a predetermined height, and may be configured in the form of a disc formed at an upper edge thereof with a stepped sill. As shown in
In addition, the frame support unit 10 may be formed on one surface thereof with at least one guide rod 14 for guiding vertical movements of the first and second fixing plates 20 and 30. In this case, as shown in
Meanwhile, a fixing unit 50 may be further installed so as to be adjacent to the frame support unit 10. As shown in
The first and second fixing plates 20 and 30 may be installed adjacent to the frame support unit 10 to fix the mesh 70. The first and second fixing plates 20 and 30 may be arranged under and over each other, so that the first and second fixing plates 20 and 30 may be spaced apart from each other by a predetermined interval to allow the mesh 70 to be inserted therebetween or withdrawn to an outside as shown in
In this case, the first and second fixing plates 20 and 30 may correspond to each other, and may have a polygonal plate shape having a predetermined area, which is preferably a rectangular plate shape.
As shown in
A fitting protrusion 24 may be formed on an outer side of one of the first and second through-holes 22 and 32 of the first and second fixing plates 20 and 30, and a fitting groove 34 may be formed on an outer side of the remaining one of the first and second through-holes 22 and 32 of the first and second fixing plates 20 and 30, so that the fitting protrusion 24 and the fitting groove 34 may be coupled to each other. In this case, it may be appropriate that the fitting protrusion 24 has a ring shape protruding from one surface of the first fixing plate 20, that is, a surface facing the second fixing plate 30, and the fitting groove 34 has a ring shape recessed from one surface of the second fixing plate 30, that is, a surface facing the first fixing plate 20. Through a coupling structure of the fitting protrusion 24 and the fitting groove 34 as described above, the first and second fixing plates 20 and 30 may overlap each other while being accurately engaged with each other, and the first and second through-holes 22 and 32 may be located on the same line without being offset to each other in a process of expanding and fusing the mesh 70. In addition, the mesh 70 may be bent along outer edges of the first and second through-holes 22 and 32 due to the fitting protrusion 24 and the fitting groove 34 while being inserted between the first and second fixing plates 20 and 30, so that the mesh 70 may be stably fixed without being easily separated.
In addition, the first and second fixing plates 20 and 30 may have at least one first guide hole 26 and at least one second guide hole 36, respectively, so that the vertical movements of the first and second fixing plates 20 and 30 may be guided. The guide rod 14 of the frame support unit 10 may pass through the first and second guide holes 26 and 36, and the first and second guide holes 26 and 36 are preferably spaced outward from the first and second through-holes 22 and of the first and second fixing plates 20 and 30 by a predetermined interval. Although four guide rods 14, four first guide holes 26, and four second guide holes 36 have been illustrated in the drawings according to one embodiment of the present invention, the embodiments are not limited thereto, and the number of guide rods 14 and first and second guide holes 26 and 36 may vary in consideration of stability or rapidity of movements of the first and second fixing plates 20 and 30 and smoothness of work.
As described above, according to the mesh fusion device 1 of one embodiment of the present invention, the top and bottom surfaces of the mesh 70 may be simultaneously pressed and fixed by using the first and second fixing plates 20 and 30, so that the mesh 70 may be fused to the one surface of the frame 60 with a uniform tension over an entire area thereof.
In other words, conventionally, a mesh is fused to a frame while expanding the mesh in a state where only both end portions of the mesh in a direction in which the mesh proceeds or four corners of the mesh are fixed, so that a tension may be applied only toward a fixed portion from a center of the mesh. Accordingly, when the frame is coupled to a cosmetic container for use, the mesh fused to the frame may be wrinkled in a direction having no tension as the mesh retains a cosmetic product, so that usability and an aesthetic impression of the mesh may be deteriorated.
Thus, according to the mesh fusion device 1 of one embodiment of the present invention, as shown in
The fusion unit 40 may fuse the mesh 70 to the one surface of the frame 60 while moving reciprocally and vertically, such that an end portion of the fusion unit 40 may pass through the first and second through-holes 22 and 32 of the first and second fixing plates 20 and 30, and may fuse the mesh 70 to the frame 60 while pressing and expanding the mesh 70.
As shown in
As shown in
In this case, it may be appropriate that the fusion unit 40, the first and second fixing plates 20 and 30, and the frame support unit 10 are located in a straight line.
The first and second fixing plates 20 and 30 may vertically move up and down together to adjust an interval between the first and second fixing plates 20 and 30 and the frame support unit 10, so that an operator may arbitrarily determine a magnitude of the tension of the mesh fitted between the first and second fixing plates 20 and 30. For example, as shown in
Meanwhile, the first and second fixing plates 20 and 30 may move up and down or may be spaced apart from each other and make close contact with each other manually by the operator, or the first and second fixing plates 20 and 30 may move up and down by a predetermined section or may be spaced apart from each other and make close contact with each other automatically by a driving unit (not shown). Similar to the vertical movement part 44 of the fusion unit 40, the driving unit is preferably operated by a pneumatic cylinder (a mechanism in which a piston performs a reciprocating motion by using a pneumatic pressure), a hydraulic cylinder (a mechanism in which a piston performs a reciprocating motion by using a hydraulic pressure), or a motor (a powered machine for rotating by receiving a power, and generating a rotational force to a shaft thereof), but is not limited thereto. The driving unit may be replaced with various mechanisms capable of reciprocally and vertically operating the first and second fixing plates 20 and 30 smoothly.
In addition, when the first and second fixing plates 20 and 30 are operated automatically, a control unit (not shown) for controlling operations of the first and second fixing plates 20 and 30 may be further included. In this case, by operating the driving unit, the control unit (not shown) may move the second fixing plate 30 upward from the first fixing plate 20 by a predetermined section so that the first and second fixing plates 20 and 30 may be spaced apart from each other or move the second fixing plate 30 downward from the first fixing plate 20 by a predetermined section so that the first and second fixing plates 20 and 30 may make close contact with each other, and may vertically move the first and second fixing plates 20 and 30 together by a predetermined height.
As described above, according to the mesh fusion device 1 of one embodiment of the present invention, through vertical reciprocating movements of the first and second fixing plates 20 and 30, the interval between the mesh 70 fitted between the first and second fixing plates 20 and 30 and the frame 60 seated on the frame support unit 10 may be changed so as to freely adjust the magnitude of the tension of the whole mesh 70 fused to the frame 60, so that the mesh 70 may be easily applied to cosmetic containers having various structures that require meshes 70 having different tensions, various types of cosmetic products mounted in the cosmetic container, or the like, and thus compatibility of the mesh 70 may be increased.
First, as shown in

While repeatedly performing the above operation, the frame 60 may be inserted into the frame support unit 10, an entire area of the top and bottom surfaces of the mesh 70 may be pressed by using the first and second fixing plates 20 and 30, and the mesh 70 may be fused to the one surface of the frame 60 by the fusion unit 40. Meanwhile, when the tension of the mesh 70 fused to the frame 60 is required to be adjusted, as shown in
