Description

Method for manufacturing a synthetic resin mask of velcro inserting type for filter exchange and a synthetic resin mask of velcro inserting type for filter exchange manufactured thereby

The present invention relates to a method for manufacturing a synthetic resin mask of a velcro inserting type for filter exchange and a synthetic resin mask of a velcro inserting type for filter exchange manufactured thereby, and, more particularly, to a one-stop injection molding using a mold to reduce manufacturing time It relates to a method for manufacturing a synthetic resin mask of a velcro inserting type for filter exchange implemented to achieve a sanitary purpose for remarkably shortening and replacing a filter, and to a synthetic resin mask of a velcro inserting type for filter exchange manufactured thereby.

In general, a mask is worn on the face or wears a respirator to prevent harmful substances from entering the body in contaminated areas, various emergencies, industrial fields where air may be polluted, areas that may be exposed to radioactive materials, etc. It is used to block the inflow of external viruses, etc.

In such a mask, antibacterially treated cotton or cloth formed on the inner surface of the mask fabric generally serves as a filter during breathing to prevent dust, foreign substances, and various bacteria from penetrating into the mask.

In general, a mask worn to avoid direct contact with outside air when working in a place where dust or odor occurs when respiratory diseases such as coughing or cold occurs, It is connected to both sides of this cover cloth and consists of a connecting string for hanging the cover cloth on both ears.

Since the manufacturing process of this conventional mask consists of a structure in which a rectangular cloth is hung on both ears, a rectangular cloth is manufactured, a hook part to hang on both ears is separately manufactured, and then the hook part is attached to the fabric again. However, there have been disadvantages in that the production process is complicated and the production time is long.

In addition, the mask manufactured in this way has disadvantages that it is difficult to reuse after storage, and the filtering function using a simple cloth filtering method is weak and the variety of manufactured products is insufficient.

On the other hand, the above-mentioned background art is technical information that the inventor possessed for the derivation of the present invention or acquired in the process of derivation of the present invention, and it cannot be said that it is necessarily a known technique disclosed to the general public before the filing of the present invention. .
