发明名称 Shoe with replaceable hygienic cartridge
摘要 A shoe with a replaceable hygienic cartridge in the heel portion thereof, forces a chemical agent through the shoe due to the intermittent compression or pumping action while a wearer of the shoe is walking, running, or using the shoe in a similar manner. The shoe includes a chemical cartridge chamber in the heel portion of the sole, into which a flexible and resilient cartridge is removably installed. The cartridge may contain any of a number of different materials or agents, such as deodorant, anti-bacterial, fungicidal, desiccant, etc., or various combinations thereof; as desired. The upper surface of the sole within the shoe contains a series of grooves or channels therein, which communicate with the cartridge chamber by a passage therebetween. A porous insole overlays the upper surface of the sole and its channels. When the shoe is worn, the intermittent compression of the heel at the beginning of each step also compresses the cartridge, forcing a portion of the material therein upwardly through the passage and channels in the upper surface of the sole, where the material is diffused through the porous insole into the interior of the shoe beneath the sole of the wearer's foot. The cartridge is quickly and easily replaced when the material therein is dissipated. The arrangement may be adapted to virtually any type of footwear, but is particularly well suited for athletic shoes having relatively soft and resilient heels, to compress the cartridge more readily.
