A cleaning device comprises a cleaning head formed as a biodegradable pocket 10. The pocket 10 is formed with a biodegradable outer layer 14 and a biodegradable inner layer 13, with an opening 11 to the pocket. The inner layer 13 is formed of high wet-strength (HWS) paper and/or polymer and the outer layer 14 is formed of lower wet-strength (LWS) paper and/or polymer. The device further comprises a handling tool 16 having an end portion (47, Fig 7) which is expandable within the pocket 10 to grip and manipulate the pocket or pouch. The device is preferably made by aligning strips of LWS and HWS paper and/or polymer and heat-sealing or welding at intervals across the strips to form a series of pockets 10 in a strip, and cutting each pocket from the series upon the strip. A process of making a sanitary device is also disclosed. |
