TECHNICAL FIELD OF THE INVENTION
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stretched body provided with a sheet-like member such as a film or a mesh suitable for being mounted on an opening or the like of a medium dish (drum) or the like loaded with cosmetics, and comprising the stretched body. The sheet member to be fixed is to be securely fixed to the frame portion.
[0002]
[Prior art]
Some of the inner plates loaded with cosmetics are provided with a stretched body that fixes and holds the sealing film in a state of being tightened by a frame to prevent the adhesion of dust and the volatilization of the cosmetics. .
[0003]
In addition, in order to enable an appropriate amount of cosmetics such as powder to be taken out, there is also provided a stretched body in which a sheet-like mesh is stretched by a frame body.
[0004]
Conventionally, this kind of stretched body is conventionally provided by placing a film or a mesh in a mold cavity of a mold for molding a container or a frame, and injecting and filling a molten resin into the cavity through a mold gate. A frame is formed around the periphery of a film or a mesh (for example, see Patent Document 1).
[0005]

JP-A-5-65105
[Problems to be solved by the invention]
By the way, the above-mentioned conventional stretched body has a state in which the edge of a sheet-like member such as a film or a mesh is stuck to the top surface of the frame body, and the sheet member is peeled off from the top surface of the frame body after long-term use. There was a defect.
[0007]
Further, when the sheet-like member is a mesh, there is a possibility that the fiber at the edge portion jumps out of the frame and the appearance is poor, and further, the mesh of the mesh located on the top surface of the frame is present. Since the contents accumulate in the openings, the usability is poor, and improvement thereof has been desired.
[0008]
An object of the present invention is to propose a new stretched body that can firmly hold a sheet-like member by a frame.
[0009]
[Means for Solving the Problems]
The present invention is a sheet-shaped member such as a film or a mesh, a stretched body composed of a frame holding the sheet-shaped member,
The frame is made of a synthetic resin molded body injected from a mold gate located just above and outside the edge of the sheet-like member,
A stretched body characterized in that the end of the sheet-like member is embedded and fixed in the frame over the entire area thereof.
[0010]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, the present invention will be described more specifically with reference to the drawings.
[0011]
FIG. 1 is an external perspective view of a stretched body according to the present invention, and FIG. 2 is a cross-sectional view thereof.
[0012]
In the figure, reference numeral 1 denotes a sheet-like member showing an example of a mesh, and 2 denotes a frame for holding the sheet-like member 1 in a taut state, and this frame is made of a synthetic resin molded body. The end of the sheet-like member 1 is embedded and fixed over the entire area.
[0013]
FIG. 3 shows a cross section of a conventional stretched body. The conventional stretched body has a problem that the sheet-like member 1 is stuck to the top surface of the frame 2 as shown in the drawing, so that the sheet-like member 1 is peeled off from the top surface of the frame 2. In the case where the member 1 is a mesh as in the embodiment of the present invention, the fibers at the ends thereof may protrude from the frame 2 and have a poor appearance, and furthermore, the fibers may be located on the top surface of the frame. However, in the stretched body according to the present invention, the end of the sheet-like member 1 is embedded and fixed substantially at the center of the frame 2 in the thickness direction. The shaped member 1 does not easily come off the frame 2.
[0014]
Further, the stretched body according to the present invention can be formed by arranging a sheet-like member 1 such as a mesh in a mold and injecting a synthetic resin into a cavity. For example, FIG. As shown in FIG. 5, when the sheet member 1 is disposed facing the mold gate 3, the sheet member 1 is deformed so as to be pushed in by the flow of the resin, as shown in FIG. It is feared that the frame 2 is formed in this state.
[0015]
For this reason, in the present invention, as shown in FIG. 6, the mold gate 3 is positioned from just above the edge of the sheet-like member 1 to the outside as shown in FIG. Avoid direct flow.
[0016]
In the embodiment of the present invention, a case where a mesh is used as the sheet-like member 1 has been described, but the present invention is also applicable to a case where a film or another member is used, and is not limited to only a mesh.
[0017]
【The invention's effect】
According to the present invention, even when an external force is applied to the sheet-like member, the sheet-like member does not easily come off the frame, so that the function of the stretched body can be maintained for a long time, and the appearance of the appearance can be kept clean. In addition, since the contents do not accumulate in the openings of the mesh located on the top surface of the frame, an easy-to-use stretched body can be obtained.
