Abstract
A filter dispenser for the storage and dispensation of individual flat filter sections. The filter dispenser includes a storage compartment with a slot shaped exit for a tube-like band, composed of two parts, and guides in proximity to the slot for the running through of the band parts. The two parts of the band are joined by continuous and releasable edges and cross connections which form pockets which seat filter sections. Upon simultaneous drawing of the parts of the band through the guides, the connections of the band between the guides and the storage compartment are broken and the encapsulated filter sections are released for removal.
