Abstract

PURPOSE:To improve the filtering effect by fitting a mask to the face, and to facilitate the storage and the transport by making the mask in a plain form in a storage or the like, by providing a process to incorporate the upper side sheet and the lower side sheet formed into a two-layer front end, at the rear end edge side, and a process to cut the incorporated upper side sheet and lower side sheet into a specific form. CONSTITUTION:The upper side sheet 1 and the lower side sheet 2 which form a two-layer front end are laminated (the rear sides are contacted M) and incorporated, while opening the front sides, to compose a mask main body N. Both sheets 1 and 2 are bent at the front sides to form two-layer front end edges 11 and 21, and the rear sides are made into a cut end edge P of an adequate form, making the depth size of the central part larger and that of the left end and the right end smaller, and they are contacted M at the rear end edges 12 and 22 along the cut end edge P. The ends of cords 3 are attached to the both ends of the two-layer front end edges 11 and 21, and a variable member 4 for reforming is fixed to the two-layer front end edge 11 of the upper side sheet 1. This simple mask is made in a plain form in the storage and on sale, and in a cubic form when it is used.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a simple mask used primarily in hospitals by patients, doctors, visitors, etc.

BACKGROUND ART This type of simple mask is generally one in which a string 3 is attached to a rectangular mask body N having a planar rectangular shape as shown in FIG.

N' As a dust mask for the workplace, see Figure 14. There are some amazing three-dimensional shapes.

O Problems to be Solved by the Present Invention Among the above-mentioned conventional technologies, the former allows manufacturing of inexpensive products, but since it has a planar shape, it does not fit well with the face.
There is a problem that the filter effect is insufficient and the bacteria removal cannot be sufficiently achieved.

The latter is made of synthetic resin non-woven fabric etc. formed into a desired three-dimensional shape, and is well suited to the face and has a sufficient filter effect, but the product cost is high and it is unsuitable for simple masks that are disposable. There is.

0 Means for Solving the Problems According to the present invention, a mask main body is constructed by integrating an upper sheet and a lower sheet having a two-layer front end portion at the rear edge side.

○Embodiment Figures 1 to 5 show a simple mask according to the first embodiment of the present invention, in which a top sheet 1 and a bottom sheet 2 are laminated (the rear sides are glued together M) and integrated, and the front side is It is opened to form a mask body N. Both sheets 12 are formed by folding the front side to form two-layer front edge parts 11 and 21, and the rear side has a cut end itp of an appropriate shape with a depth dimension that is dog in the center part and small in the left and right side parts. Two-layer trailing edge 1 along the cut edge P
Glue M with 2.22.

The ends of the string 3 were adhered to both sides of the two-layer front edge 11 and 21, and in the example, a variable shape member 4 for shaping was fixed to the two-layer front edge 11 of the top sheet 1.

In the second embodiment shown in FIGS. 6 to 10, the top sheet 1 and the bottom sheet 2 are constructed by folding two sheet materials in half at the center to form a two-layer structure. Cut off a portion and cut only both sides of the rear end edge of the two layers.
This differs from the first embodiment in that only the rear edge sides along the cut edge P' are glued together, and both the jets 2 are integrated by bending Q at the center and gluing both sides. ,
The rest is the same as the first embodiment.

It goes without saying that the side edges may be inclined as shown in the virtual AIIR to make the front side narrower than the rear side. Also virtual! IT indicates a folding line when forming a three-dimensional shape.

Top sheet 1. The bottom sheet 2 may be made of any material as long as it is a breathable sheet material. For example, non-woven paper, gauze, etc. are used.

As the variable shape member 4, a member that can be deformed into an appropriate shape by the user's hands and maintain the deformed state, such as a metal wire or a soft synthetic resin wire, can be used.

The simple mask of the present invention has a planar shape as shown in FIGS. 4 and 9 when stored and sold, but when used, it has a planar shape as shown in FIGS. 5 and 9.
It has a three-dimensional shape as shown in FIG.

FIG. 11 shows the manufacturing process of the simple mask of the first embodiment,
The sheet roll 10 for the top sheet 1 is wrapped around the twisted sheet material 111iIII in a bamboo shape to form the two-layer front edge portions 11 and 21, and the two-layer state is formed at positions shifted in the front-rear direction. Supply (A・A').

The central portion of the two-layered portion near the cutting line is glued M to integrate both sheets 2 (B).

Cut along the continuous S-shaped cutting line S1 (C).

The mask body is completed by cutting along the transverse cutting line S2 (D).

FIG. 12 shows the manufacturing process of the simple mask of the second embodiment, in which both side edge portions of the sheet material supplied from a single sheet roll 10' are bent into a bifinger shape at the center of the front end of the two layers. It has a two-layer structure consisting of a bent upper sheet 1 and a lower sheet 2 (B').

4/T button r Glue the vicinity of the cut part in one example (C'').

A portion of the sheet material is removed by cutting along the cutting line s i',p (Do).

+2 Cut from the cutting line 52' to complete the mask body (
E゛).

Attach the flexible member 4 as desired and easily. Complete the mask.

Q Effects of the Invention The simple mask of the present invention can be manufactured with desired quality (from high-end products to low-cost disposable products) by selecting the sheet material.

Furthermore, although it is a low-cost product, it has a three-dimensional shape when used, which allows it to fit around the face and enhance the filter effect, and when stored, it can be stored in a flat shape.
It has the effect of facilitating movement.
