PROBLEM TO BE SOLVED: To provide a filter retainer that can be manufactured easily, can be formed into a sheet shape entirely on storage, can mount filters of various shapes, prevents the temperature of extracted liquid from decreasing easily, suppress the amount of generation of dust due to usage, and eliminates the need for frequent washing after usage. SOLUTION: Structure is made for returning a bent part to its original position so that an entire part can be formed into a sheet shape on accommodation. The structure of a filter pretension part is formed so that a fitted filter can be pinched at a plurality of parts to mount filters in various shapes. The shape and elasticity of the retention part are selected so that the mounted filters can be peeled off after usage to prevent the retainer from being disposed. Structure is adopted to prevent the extraction liquid from touching the retention part to eliminate the need for frequent washing. |
