Durable anti-mold packet

Abstract

A durable anti-mold packet comprises a holding pouch, an absorption material and an anti-mold evaporation substance. The holding pouch has an upper edge, a lower edge, a left edge and a right edge. The left edge and right edge are folded and overlapped to form a housing space and an overlapped seam edge. The upper edge and lower edge are pressed and sealed. The overlapped seam edge is partially pressed and sealed to form an evaporation vent communicating with the exterior. The anti-mold evaporation substance is coated onto the absorption material which is held in the housing space. Therefore a greater amount of the anti-mold evaporation substance can be absorbed by the absorption material and the anti-mold evaporation substance can be slowly released from the absorption material to increase use duration of the anti-mold packet and provide anti-mold effect for a longer period to meet use requirements.

What is claimed is: 
     
         1 . A durable anti-mold packet, comprising:
 a holding pouch including an upper edge, a lower edge, a left edge and a right edge, the left edge and the right edge being folded and overlapped to form a housing space and an overlapped seam edge, the upper edge and the lower edge being pressed and sealed, the overlapped seam edge being partially pressed and sealed to form an evaporation vent communicating with exterior;   an absorption material; and   an anti-mold evaporation substance coated onto the absorption material which is held in the housing space.   
     
     
         2 . The durable anti-mold packet of  claim 1  further including a sealing patch to cover and seal the evaporation vent. 
     
     
         3 . The durable anti-mold packet of  claim 1 , wherein the evaporation vent is located at a center of the overlapped seam edge. 
     
     
         4 . The durable anti-mold packet of  claim 1 , wherein the holding pouch is made of a material selected from the group consisting of nylon and aluminum foil. 
     
     
         5 . The durable anti-mold packet of  claim 1 , wherein the absorption material is a non-woven fabric. 
     
     
         6 . The durable anti-mold packet of  claim 1 , wherein the holding pouch includes multiple sets clustered and wound in a roll film.
