Abstract

<P>PROBLEM TO BE SOLVED: To solve a problem that it is difficult to install a thin, soft, disposable and replaceable filter for preventing pollen and bacteria inside a mask with a bare hand. <P>SOLUTION: This insertion device formed by folding a thin film or paper into two is so constituted as to easily install the disposable and replaceable filter 2 for preventing the pollen and the bacterial inside the mask. Its method is to pick up the filter 2 with the doubled insertion device 1, insert the insertion device 1 picking up the filter 2 from one mouth 7 of pocket mouths in the rear face of the mask for taking in/out the insertion device 1, and taking out the tip of the insertion device 1 from the other mouth 7. The filter 2 in a recess 3 in the tip of the insertion device is picked up and fixed, and then the insertion device 1 alone is drawn back and taken out from the mount 7 of the pocket. The filter can be thus stored and installed in the center of the mask. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

  The present invention relates to a technique for inserting a filter into a mask.

    There has been no attempt to insert a filter used for a mask with an insertion tool.

    Disposable and replaceable filters that prevent pollen and bacteria used in masks must be replaced as dust, dust, pollen, and bacteria attach to them when they are used more frequently. In particular, thin, soft filters that are charged with electricity tend to get stuck in things, and it was difficult to spread them flatly inside the mask with bare hands. Therefore, a method for easily attaching the filter is necessary.

  Use a thin film or paper fold-in insert to prevent pollen and bacteria, insert a disposable filter that can be replaced between the insert folds, and insert the filter into the mask in a flat shape Then, when the filter in the hollow portion at the tip of the insertion tool is picked and then only the insertion tool is pulled back, the filter fits in the center of the mask and can be attached.

  As described above, a thin and soft filter that prevents pollen and bacteria and can be replaced in a disposable manner can be easily and easily mounted inside the mask.

  Embodiments of the invention will be described with reference to the drawings.

Embodiments will be described with reference to the drawings. FIG. 1 is a perspective view of a state in which a filter 2 is sandwiched by an insertion tool 1 according to the present invention. The insertion tool 1 is a thin film folded in half. The material of the film may be transparent or translucent plastic so that the condition of the filter 2 can be seen, but it is not necessarily transparent. As long as the filter 2 is sandwiched, the thickness of the transparent file into which a commercially available document is placed is sufficient. The size is for sandwiching the filter 2 of the mask, and varies depending on the size of the filter 2, but it is a rectangle as shown in FIG. 1, and the shorter one may be 4 cm to 10 cm and the longer one may be about 6 cm to 15 cm. FIG. 2 is a front view of the insertion tool 1. FIG. 3 is a plan view of the insertion tool 1, and a dent 3 at the left end is a dent that makes it easy to pick the filter 2 of claim 2. FIG. 4 is a back surface of a mask to which the filter 2 can be attached. As shown in the figure, it consists of three pockets, that is, a pocket central portion 4 and pocket edges 5 and 6, and these three portions hold the filter. The pocket mouths 7 and 8 are portions into which the insertion tool can be inserted and removed.
The filter 2 is attached to the back of the mask by inserting one of the two mouths 7 and 8 of the pocket on the back of the mask of FIG. 5, the insertion tool 1 with the filter 2 sandwiched from the mouth 7 of the pocket in FIG. , Pass under the center of the pocket 4 and exit from the mouth 8 of the other pocket, then exit the mouth 8 of the pocket and insert the filter 1 on the end 6 of the pocket with the filter 1 While picking the end of the filter 2 in the recess 3, only the insertion tool 1 is pulled out from the mouth 7 of the pocket. Then, as shown in FIG. 6, the filter 2 is located at the pocket central portion 4 and is located above the pocket edges 5 and 6 and fits in the center of the mask as a whole. In this way, the entire filter 2 is flatly mounted inside the mask if it is inserted under the pocket edges 5 and 6.
In the embodiment, plastic is used as the material of the insertion tool. However, paper may be used as long as it has a thickness and hardness that can hold the filter 2.

In the embodiment, the back surface of the mask is structured to have a pocket for inserting and removing the filter. However, the filter of the present invention can be attached to a conventional gauze mask to prevent pollen and bacteria. Function can be enhanced. In addition, compared with a mask having a structure in which the entire mask is disposable, since only the filter is disposable, environmental issues are also considered.
