[0043] Hereinafter, a mesh fusion device for a cosmetic container according to one embodiment of the present invention will be described with reference to FIGS. 1 to 10. In the following, preferred embodiments of the present invention will be described with reference to the accompanying drawings, and the mesh fusion device for the cosmetic container according to the present invention preferably includes the following components, but the embodiments are not limited thereto.

[0044] FIG. 1 is a perspective view showing a mesh fusion device according to one embodiment of the present invention, and FIG. is an exploded perspective view showing the mesh fusion device according to one embodiment of the present invention.

[0045] 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.

[0046] Hereinafter, the mesh fusion device for the cosmetic container according to one embodiment of the present invention will be described for each component.

[0047] FIG. 3 is a perspective view illustrating a state in which first and second fixing plates are spaced apart from each other according to one embodiment of the present invention, and FIG. 4 is a perspective view illustrating a state in which a frame is seated on a frame support unit according to one embodiment of the present invention.

[0048] 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.

[0049] 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 FIG. 4, the frame 60 may be configured in the form of a ring including a side wall part 62 and a horizontal extension part 64 bent inward of the side wall part 62, and may be seated on the frame seating part 12. In this case, the frame 60 may be seated on the frame seating part 12 such that the side wall part 62 of the frame 60 may surround an outer wall of the frame seating part 12, and the horizontal extension part 64 may cover an edge portion of the frame seating part 12. Accordingly, the frame 60 may be maintained in a fixed state without fluctuating due to an external impact during a process of fusing the mesh 70. In this case, it may be preferable to allow a diameter of the frame seating part 12 to be equal to or relatively smaller than an inner diameter of the frame 60. However, the shape of the frame seating part 12 is not limited to a disc shape, and may vary according to the shape or the size of the frame 60 seated on the frame seating part 12.

[0050] 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 FIG. 2, the guide rod 14 may extend upward from a corner of the frame support unit 10, and may pass through the first and second fixing plates 20 and 30 to guide the vertical movements of the first and second fixing plates 20 and 30.

[0051] Meanwhile, a fixing unit 50 may be further installed so as to be adjacent to the frame support unit 10. As shown in FIG. 1, the fixing unit 50 may include a rotation shaft 52 and a fixing part 54 rotated by the rotation shaft 52, in which the fixing part 54 may be rotated by a predetermined angle while being maintained horizontally, and may make close contact with one side surface of the frame support unit 10 to prevent the frame support unit 10 from fluctuating. However, at least two fixing units 50 are preferably provided on an outer side of the frame support unit 10 to stably fix the frame support unit 10.

[0052] FIG. 5 is a perspective view illustrating a state in which a mesh is inserted between the first and second fixing plates according to one embodiment of the present invention, and FIG. 6 is a perspective view illustrating a state in which the first and second fixing plates overlap each other according to one embodiment of the present invention.

[0053] 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 FIG. 5, and the first and second fixing plates 20 and 30 may make close contact with each other to allow the mesh 70 to be fixedly fitted therebetween as shown in FIG. 6. In this case, as shown in FIG. 3, while the first fixing plate 20 arranged on a lower side among the first and second fixing plates 20 and 30 is fixed, only the second fixing plate 30 arranged on an upper side among the first and second fixing plates 20 and 30 may move reciprocally and vertically by a predetermined interval so that the first and second fixing plates 20 and 30 may be spaced apart from each other or may make close contact with each other, which is to maintain a constant interval between the first fixing plate 20 and the frame support unit 10.

[0054] 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.

[0055] As shown in FIG. 2, the first and second fixing plates 20 and 30 may have first and second through-holes 22 and 32, respectively, in which bottom and top surfaces of the mesh 70 fitted between the first and second fixing plates 20 and 30 may be at least partially exposed to the outside through the first and second through-holes 22 and 32, and the fusion unit 40 may be inserted into the first and second through-holes 22 and 32. Therefore, the first and second through-holes 22 and 32 preferably have the same diameter as the fusion unit 40 or a diameter that is relatively larger than a diameter of the fusion unit 40. Meanwhile, the first through-hole 22 among the first and second through-holes 22 and 32 may serve as an inlet into which the frame 60 is inserted before the mesh 70 is located between the first fixing plate 20 and the second fixing plate 30. In more detail, in order to simplify the process of fusing the mesh 70, the first fixing plate 20 spaced apart from the frame support unit 10 by a predetermined interval may be fixed, only the second fixing plate 30 may move upward as shown in FIG. 3, and the frame 60 may be inserted into the first through-hole 22 of the first fixing plate 20 so as to be seated on the frame seating part 12 of the frame support unit 10 as shown in FIG. 4.

[0056] 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.

[0057] 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.

[0058] 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.

[0059] 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.

[0060] Thus, according to the mesh fusion device 1 of one embodiment of the present invention, as shown in FIG. 6, the first fixing plate 20 serving as a lower plate and the second fixing plate 30 serving as an upper plate may overlap each other, so that a top surface of the first fixing plate 20 except for the first through-hole 22 and a bottom surface of the second fixing plate 30 except for the second through-hole 32 may strongly press an entire area of a predetermined region of the top and bottom surfaces of the mesh 70 located therebetween so as to stably fix the mesh 70. Thereafter, the mesh 70 may be fused to the one surface of the frame 60 while being pressed and pulled by the fusion unit 40. Accordingly, as shown in FIG. 8, the whole mesh 70 may expand from a central portion toward an edge portion of the frame 60 with a uniform tension, so that the mesh 70 may be always maintained taut even when the mesh 70 is used for a long period of time while retaining the cosmetic product.

[0061] FIG. 7 is a front view illustrating a state in which the mesh is expanded and fused as a fusion unit moves downward according to one embodiment of the present invention, FIG. 8 is a plan view illustrating a state in which the mesh is expanded and fused by the fusion unit according to one embodiment of the present invention, and FIG. 9 is a front view illustrating a state in which the first and second fixing plates are spaced apart from each other as the fusion unit moves upward according to one embodiment of the present invention.

[0062] 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.

[0063] As shown in FIG. 1, the fusion unit 40 may include a fusion part 42 for fusing the mesh 70 to the frame 60 by pressing the mesh 70, a vertical movement part 44 for reciprocally and vertically moving the fusion part 42, and a support body 46 for supporting and fixing the fusion part 42 and the vertical movement part 44. In this case, the fusion part 42 may be configured as: a hot-plate fusion device, an impulse sealer, or a hot-air fusion device, which heats from an outside; or a high-frequency fusion device or an ultrasonic fusion device, which heats a material. In particular, the fusion part 42 is preferably an ultrasonic fusion device. The vertical movement part 44 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 vertical movement part 44 may be replaced with various mechanisms capable of reciprocally and vertically operating the fusion part 42 smoothly.

[0064] As shown in FIG. 7, the fusion part 42 of the fusion unit 40 may move downward by the vertical movement part 44 so as to be inserted into the first and second through-holes 22 and 32, and an end portion of the fusion part 42 may sequentially press the mesh 70 fitted between the first and second fixing plates 20 and 30 to expand the whole mesh 70 as shown in FIG. 8 and fuse the mesh 70 to the one surface of the frame 60 seated on the frame support unit 10. In addition, as shown in FIG. 9, the fusion part 42 of the fusion unit 40 may move upward by the vertical movement part 44 so as to exit from the first and second through-holes 22 and 32, and the second fixing plate 30 among the first and second fixing plates 20 and 30 may sequentially move upward, so that the mesh 70 may be withdrawn or moved.

[0065] 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.

[0066] FIG. 10 is a perspective view illustrating a state in which an interval between the first and second fixing plates and the frame support unit is adjusted as the first and second fixing plates move according to one embodiment of the present invention.

[0067] 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 FIG. 9, when the first and second fixing plates 20 and move away from the frame support unit 10, an interval between the mesh 70 fixed between the first and second fixing plates 20 and 30 and the frame 60 seated on the frame support unit 10 may be increased, so that when the fusion unit 40 presses the mesh 70 to fuse the mesh 70 to the frame 60, the mesh 70 may be fused to the frame 60 while being relatively more expanded so as to increase the tension. Conversely, when the first and second fixing plates 20 and 30 move close to the frame support unit 10, the interval between the mesh 70 fixed between the first and second fixing plates 20 and 30 and the frame 60 seated on the frame support unit 10 may be decreased, so that when the fusion unit 40 presses the mesh 70 to fuse the mesh 70 to the frame 60, the mesh 70 may be fused to the frame 60 while being relatively less expanded so as to decrease the tension.

[0068] 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.

[0069] 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.

[0070] 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.

[0071] FIGS. 3 to 10 are views illustrating an operation of the mesh fusion device according to one embodiment of the present invention, and an operation structure of the mesh fusion device according to one embodiment of the present invention will be described with reference to FIGS. 3 to 10 as follows.

[0072] First, as shown in FIG. 3, the first and second fixing plates 20 and 30 may be spaced apart from each other by a predetermined interval. In this case, while the first fixing plate 20 arranged on the lower side among the first and second fixing plates 20 and 30 is fixed, only the second fixing plate 30 arranged on the upper side among the first and second fixing plates 20 and 30 may vertically move by a predetermined interval along the guide rod 14 so as to separate the first and second fixing plates 20 and 30 from each other.

[0073] Then, as shown in FIG. 4, the frame 60 may be inserted into the first through-hole 22 of the first fixing plate 20 and seated on the frame seating part 12 of the frame support unit 10. In this case, the frame 60 may be stably seated on the frame seating part 12 such that the side wall part 62 of the frame 60 may surround the outer wall of the frame seating part 12, and the horizontal extension part 64 may cover the edge portion of the frame seating part 12.

[0074] Thereafter, as shown in FIG. 5, an elastic mesh 70 may be inserted between the first and second fixing plates 20 and 30 that are spaced apart from each other by a predetermined interval. In this case, the elastic mesh 70 may be inserted between a plurality of guide rods 14, and placed on an upper portion of the fitting protrusion 24 of the first fixing plate 20.

[0075] Then, as shown in FIG. 6, the second fixing plate 30 may move downward to overlap the first fixing plate 20. Accordingly, the top surface of the first fixing plate 20 except for the first through-hole 22 and the bottom surface of the second fixing plate 30 except for the second through-hole 32 may press an entire area of a predetermined region of the top and bottom surfaces of the mesh 70 located therebetween so as to fix the mesh 70.

[0076] Thereafter, as shown in FIG. 7, the fusion part 42 of the fusion unit 40 may move downward, so that the mesh 70 may be fused to the one surface of the frame 60. In this case, the fusion part 42 of the fusion unit 40 may move downward by the vertical movement part 44 so as to be inserted into the first and second through-holes 22 and 32, and the end portion of the fusion part 42 may sequentially press the mesh 70 fitted between the first and second fixing plates 20 and 30 to expand the whole mesh 70 as shown in FIG. 8 and fuse the mesh 70 to the one surface of the frame 60 seated on the frame support unit 10.

[0077] Then, as shown in FIG. 9, the fusion part 42 of the fusion unit 40 may move upward, and the second fixing plate 30 may be spaced apart from the first fixing plate 20 by a predetermined interval. In this case, the fusion part 42 of the fusion unit 40 may move upward by the vertical movement part 44 so as to exit from the first and second through-holes 22 and 32, and the second fixing plate 30 among the first and second fixing plates 20 and 30 may sequentially move upward, so that the mesh 70 may be withdrawn or moved.

[0078] 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 FIG. 10, 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 by reciprocally and vertically moving the first and second fixing plates 20 and 30.

[0079] Although the above description has been made with reference to illustrative embodiments and drawings as well as certain matters such as specific elements, the embodiments are provided for an overall understanding of the present invention, so the present invention is not limited to the embodiments. It will be understood by a person having ordinary skill in the art to which the present invention pertains that various changes and modifications can be made from the above description. Therefore, the spirit of the present invention should not be construed as being limited to the embodiments described herein, and it will be understood that the scope of the spirit of the present invention encompasses the scope of the appended claims and all variations equivalent thereto.
