Description of the Related Art A respirator is worn when working in an environment harmful to the human body due to floating dust and toxic gas, such as a dust mask and a gas mask, to prevent workers from inhaling harmful dust and gas. It is devised. And the filter used for this under such harmful environment,
It is provided to ensure the breathing of clean air, and is made by folding a filter medium such as filter paper and filter cloth. This filter is used in a state where it is incorporated in a case, and is used in a state where it is not contained in a case. The filter not contained in the case is used as a filter alone, and as such, has a low strength, is liable to be deformed, and has a limit in increasing the effective filtration area. Therefore, the filter is often used by being incorporated in a case.

という問題点があった。[0003] As a method of incorporating a filter into a case, a side surface of the filter is sandwiched between cases, or a side surface of the filter is sealed. The method of sealing the side of the filter is to cut the filter into a circular shape, put it into a circular case or mold (hereinafter simply referred to as the case in any case), and inject the sealing agent into the gap between the case and the filter to integrate At this time, the sealing agent is injected while rotating the filter. At this time, make sure that the filter inside does not move from the center, that the gap between the filter and the case where the sealing agent flows is constant, and that the filter does not deviate from the center due to rotation. For this purpose, the filter is fixed to the case with an adhesive or the like. However, in such a method, the filter has to be cut into a circle so as to fit the case, and when the filter is fixed with an adhesive, there is a problem that the effective filtration area is reduced and the ventilation resistance is increased. .

The present invention was completed as a result of various studies on a method that does not cut the filter, and the purpose of the present invention is to use a sealing agent by fixing the filter so that the filter and the case are spaced at a constant interval without using an adhesive. It is an object of the present invention to provide a polygonal filter which is easy to inject and can be easily manufactured without cutting the filter into a circle so as to fit a case.

It is a polygonal filter used for a respiratory protection device. That is, in the present invention, when the filter is put in a circular case and the side surface is sealed, a filter which has been processed into a polygon in advance so that the vertex of the polygon is in contact with the inner peripheral surface of the case is used, and this is used in the case. , The apex of the polygonally shaped filter contacts the inner peripheral surface of the case, so that the filter is fixed to the center of the case. Then, a gap is formed between the circular case and the polygonal side, and the sealing agent is poured into the gap and sealed.

The respirator in the present invention refers to a dust mask designed to prevent workers from inhaling harmful dust. Refers to filter paper and the like provided to ensure respiration. Then, the present invention cuts this filter into polygons. The polygon is not particularly limited, and may be any of a quadrangle to a polygon, but an octagon is preferable from the viewpoint of workability and ease of fixing in contact with the inner peripheral surface of the case. At this time, the polygon is cut such that the vertices of the polygon are in contact with the inner peripheral surface of the case. To be in contact with the inner surface of the case means that all the vertices of the polygon do not need to be in contact with the inner surface of the case; The injection of the sealing agent into the gap between the side surface of the filter and the inner peripheral surface of the case is performed in the same way as in the conventional case, by injecting the sealing agent and rotating the case, and the sealing agent is conventionally used. Can be used.

This filter is processed into an octagon by cutting a corner, for example (see FIG. 2). Next, this octagon filter is placed in a circular case (see FIG. 3). At this time, the filter is fixed by making the apex of the filter contact the inner peripheral surface of the circular case. Thereafter, a sealing agent is poured into the gap formed between the circular case and the octagonal sides without blocking to seal the side surface of the filter (see FIG. 4).

タを得ることができた。As described above, according to the present invention, a filter used as a filter medium is processed into a polygon in advance, so that the filter can be easily sealed without fixing the filter with an adhesive or the like. The filter could be fixed to the center of the case even when the case was rotated to inject the sealing agent. In addition, a filter having the same performance can be obtained with a smaller amount of the filter than using a circular filter.
