Abstract
Description
[Technical Field]
[0001] The present invention relates to a cosmetic container. [Background technology]
[0002] Conventionally, cosmetic containers (compact containers) have been known which include a cylindrical container body with a bottom for accommodating the contents, a frame body made of synthetic resin which is inserted into and fixed in the container body, and a stretchable mesh body which is provided between the lower end of the frame body and the bottom of the container body and covers the lower opening of the frame body, with the mesh body fixed to the edge of the lower opening of the frame body. In this cosmetic container, when an applicator such as a puff is pressed against the upper surface of the mesh body, the contents of the storage space are adhered to the applicator through the mesh openings of the mesh body. [Prior art documents] [Patent documents]
[0003] [Patent Document 1] Publication No. 8-11 Summary of the Invention [Problem to be solved by the invention]
[0004] In this type of cosmetic container, as the contents decrease, the distance between the bottom surface of the mesh body and the top surface of the contents increases, and therefore the amount of pressure needed to apply the contents to the applicator also increases, so there is a need to increase the bonding strength between the mesh body and the bottom opening edge of the frame. For example, if the mesh body has coarse mesh, there is a concern that the bonding strength between the mesh body and the frame will be insufficient.
[0005] The present invention provides a cosmetic container that can increase the bonding strength between a mesh body and the lower opening edge of a frame body. [Means for solving the problem]
[0006] A cosmetic container according to one aspect of the present invention comprises a bottomed cylindrical container body in which contents are stored, a frame body made of synthetic resin that is inserted into and fixed in the container body, and an elastic mesh body that is provided between the lower end of the frame body and the bottom of the container body and covers the lower opening of the frame body, wherein the space surrounded by the mesh body and the bottom of the container body is the storage space for the contents, the mesh body is fixed to the edge of the lower opening of the frame body, and a recess that is recessed upward is formed in the edge of the lower opening of the frame body, and the mesh body enters the recess and is fixed to the inner surface of the recess.
[0007] Since the mesh body enters a recess formed in the lower opening edge of the frame body and is fixed to the inner surface of the recess, the bonding area between the mesh body and the lower opening edge of the frame body increases, thereby increasing the bonding strength between the mesh body and the lower opening edge of the frame body.
[0008] The inner circumferential surface of the inner surface of the recess that is located radially inward may extend radially outward as it extends upward, and the inclination angle of the outer circumferential surface of the inner surface of the recess that is located radially outward with respect to the vertical direction may be smaller than the inclination angle of the inner circumferential surface of the recess with respect to the vertical direction.
[0009] The inner surface of the recess extends radially outward as it moves upward, and the angle of inclination of the inner surface of the recess relative to the vertical direction is greater than the angle of inclination of the outer surface of the recess relative to the vertical direction. This makes it possible to ensure the thickness of the base of the convex portion that forms the recess in the molding die for the frame body, thereby reducing damage to the convex portion.
[0010] A gate mark may be provided on the outer peripheral surface of the frame at a position radially opposite the recess.
[0011] A gate mark is provided on the outer peripheral surface of the frame body at a position radially opposite the recess, and the angle of inclination of the outer peripheral surface of the recess in the vertical direction is smaller than the angle of inclination of the inner peripheral surface of the recess in the vertical direction.Therefore, when the frame body is injection molded using the mesh body as an insert, the injection pressure of the molten resin from the gate presses the mesh body against the outer peripheral surface of the convex portion of the molding die for the frame body, allowing the mesh body to be securely fixed to the inner surface of the recess. [Effects of the Invention]
[0012] According to one aspect of the present invention, the strength of the bond between the mesh body and the lower opening edge of the frame body can be increased. [Brief explanation of the drawings]
[0013] [Figure 1] 1 is a vertical cross-sectional view of a cosmetic container according to an embodiment of the present invention; [Figure 2] FIG. 2 is an enlarged view of a portion of FIG. DETAILED DESCRIPTION OF THE INVENTION
[0014] Hereinafter, a cosmetic container according to one embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 1, the cosmetic container 1 according to this embodiment includes a cylindrical container body 11 with a bottom, a frame body 12, a cylindrical covering member 13 with a bottom, and a mesh body . The container body 11, the frame body 12, and the covering member 13 are arranged coaxially on a common axis.
[0015] Hereinafter, the common axis will be referred to as the container axis O, the open end side of the container body 11 along the container axis O will be referred to as the upper side, the bottom 11a side of the container body 11 along the container axis O will be referred to as the lower side, the direction along the container axis O will be referred to as the vertical direction, the direction intersecting the container axis O when viewed from the vertical direction will be referred to as the radial direction, and the direction circumferential around the container axis O when viewed from the vertical direction will be referred to as the circumferential direction.
[0016] The contents are accommodated in the container body 11. A lid body 15 is removably attached to the top of the container body 11. The top opening of the container body 11 is releasably closed by the lid body 15. A male thread portion to which the lid body 15 is removably screwed is formed on the outer peripheral surface of the top of the container body 11. The lid body 15 may be removably fitted to the top of the container body 11.
[0017] The frame 12 is inserted into and fixed in the container 11. The frame 12 may be connected to the upper end of the container 11 via a hinge and formed integrally with the container 11. The frame 12 is made of a synthetic resin material. A first flange 12a is formed at the upper end of the frame 12, protruding radially outward and positioned at the upper opening edge of the container 11. The first flange 12a extends continuously over the entire circumferential length. The outer diameter of the upper portion of the frame 12 is larger than the outer diameter of the lower portion of the frame 12. The outer peripheral surface of the lower portion of the frame 12 is spaced radially inward from the inner peripheral surface of the container 11. The outer peripheral surface of the lower portion of the frame 12 extends straight in the vertical direction. A groove extending vertically is formed in the outer peripheral surface of the upper portion of the frame 12, and the portion of the outer peripheral surface of the upper portion of the frame 12 other than the groove abuts the inner peripheral surface of the container 11. This groove is located below the upper end of the frame 12. When the frame 12 is inserted into the container 11, air in the container 11 is released to the outside through this groove. It is not necessary to form a groove on the outer peripheral surface of the upper part of the frame body 12.
[0018] The covering member 13 is made of a transparent synthetic resin material and is fitted into the frame body 12. The covering member 13 is in close contact with the inner peripheral surface of the frame body 12 and the upper surface of the mesh body 14, and prevents the contents of the storage space X (described later) from scattering through the mesh of the mesh body 14. The applicator Y is housed inside the covering member 13. A second flange portion 13a is formed at the upper end of the covering member 13, protruding radially outward and positioned on the upper surface of the first flange portion 12a of the frame body 12. The second flange portion 13a extends continuously over the entire circumferential length. A gripping projection 13b is connected to a circumferential portion of the outer peripheral edge of the second flange portion 13a. The gripping projection 13b and the second flange portion 13a are integrally formed, and have the same plate thickness. The gripping projection 13b is folded back radially inward around the connection portion with the second flange portion 13a. The gripping projection 13b is supported so as to be rotatable in the radial direction around the connection portion with the second flange portion 13a.
[0019] The covering member 13 may not be provided. Alternatively, a configuration including a cylindrical container body with a bottom and an inner tray that is housed within the container body and contains the contents may be employed as container body 11. In this configuration, frame 12 may be inserted into and fixed to the inner tray, or may be connected to the upper end of the inner tray via a hinge and formed integrally with the inner tray.
[0020] The mesh body 14 is stretchable and elastically deformable. The mesh body 14 is formed into a sheet shape with a mesh formed by weaving stretchable fibers. Examples of the fiber material include nylon resin, or a mixture of polyethylene terephthalate and urethane resin. The mesh body 14 is provided between the lower end of the frame body 12 and the bottom 11a of the container body 11, and covers the lower opening of the frame body 12. The space surrounded by the mesh body 14 and the bottom 11a of the container body 11 is the storage space X for the contents. The mesh body 14 is fixed to the edge of the lower opening of the frame body 12 by, for example, adhesive bonding or welding. The outer periphery of the mesh body 14 is fixed to the edge of the lower opening of the frame body 12. In the illustrated example, the portion of the upper surface of the mesh body 14 that is located inside the frame body 12 is flush with the edge of the lower opening of the frame body 12. The mesh body 14 is provided between the edge of the lower opening of the frame body 12 and the bottom 11a of the container body 11.
[0021] In this embodiment, an upwardly recessed recess 16 is formed at the edge of the lower opening of the frame body 12. The recess 16 is a circumferential groove that extends continuously over the entire circumferential length. The mesh body 14 enters the recess 16 and is fixed to the inner surface of the recess 16.
[0022] As shown in Figure 2, the inner surface of the recess 16 is composed of an inner circumferential surface 16a facing radially outward, an outer circumferential surface 16b facing radially inward, and an upper surface 16c that faces downward and connects the upper ends of the inner circumferential surface 16a and the outer circumferential surface 16b in the radial direction. An upper surface 16c of the recess 16 has a curved shape recessed upward in a vertical cross section along the radial direction. An inner peripheral surface 16a of the recess 16 extends radially outward as it extends upward. An outer peripheral surface 16b of the recess 16 extends straight in the vertical direction. Alternatively, the outer peripheral surface 16b of the recess 16 may extend radially inward as it extends upward. The angle of inclination of the outer peripheral surface 16b of the recess 16 relative to the vertical direction is smaller than the angle of inclination of the inner peripheral surface 16a of the recess 16 relative to the vertical direction. Note that the angle of inclination of the outer peripheral surface 16b of the recess 16 relative to the vertical direction may be equal to or larger than the angle of inclination of the inner peripheral surface 16a of the recess 16 relative to the vertical direction.
[0023] The radial size of the recess 16 is more than twice the thickness of the mesh body 14, and a radial gap is provided between the portion of the outer periphery of the mesh body 14 that is located on the inner periphery 16a of the recess 16 and the portion that is located on the outer periphery 16b of the recess 16. Of the outer periphery of mesh body 14, the radial size of outer edge 14a located radially outward from recess 16 is larger than the radial size of portion 14b located radially inward from recess 16. Note that, of the outer periphery of mesh body 14, the radial size of outer edge 14a may be smaller than the radial size of portion 14b located radially inward from recess 16.
[0024] A gate mark is provided on the outer peripheral surface of the frame body 12 at a position radially opposite the recess 16. The gate mark is located on the outer peripheral surface of the frame body 12 above the outer edge 14a of the mesh body 14. The inner peripheral surface of the lower end of the frame body 12 extends radially outward as it moves upward along the inner peripheral surface 16a of the recess 16 in a vertical cross section along the radial direction. Note that the inner peripheral surface of the lower end of the frame body 12 may extend, for example, straight in the vertical direction.
[0025] As described above, in the cosmetic container 1 according to this embodiment, the mesh body 14 enters the recess 16 formed on the lower opening edge of the frame body 12 and is fixed to the inner surface of the recess 16, thereby increasing the bonding area between the mesh body 14 and the lower opening edge of the frame body 12 and enhancing the bonding strength between the mesh body 14 and the lower opening edge of the frame body 12.
[0026] The inner surface 16a of the recess 16 extends radially outward as it goes upward, and the angle of inclination of the inner surface 16a of the recess 16 relative to the vertical direction is greater than the angle of inclination of the outer surface 16b of the recess 16 relative to the vertical direction, so that it is possible to ensure the thickness of the base of the convex portion that forms the recess 16 in the molding die of the frame body 12, thereby reducing damage to the convex portion.
[0027] A gate mark is provided on the outer peripheral surface of frame body 12 at a position radially opposite recess 16, and the angle of inclination of outer peripheral surface 16b of recess 16 in the vertical direction is smaller than the angle of inclination of inner peripheral surface 16a of recess 16 in the vertical direction.Therefore, when frame body 12 is injection molded using mesh body 14 as an insert, the injection pressure of molten resin from the gate presses mesh body 14 against the outer peripheral surface of the convex portion of the molding die for frame body 12, allowing mesh body 14 to be securely fixed to the inner surface of recess 16.
[0028] The technical scope of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.
[0029] For example, the recesses 16 may be provided intermittently at intervals in the circumferential direction on the edge of the lower opening of the frame 12. In this case, the size of the recesses 16 in the circumferential direction may be larger than the intervals. The position of the gate mark on the frame 12 may be changed as appropriate. The cosmetic container 1 is not limited to a jar container, and other forms such as a compact container may also be used.
[0030] In addition, within the scope of the spirit of the present invention, it is possible to replace the components in the above-described embodiments with well-known components as appropriate, and the above-described embodiments and the above-described variations may be combined as appropriate.
