Cartridge for hand-operated film applicator

摘要

A cartridge for a film applicator has a body having parallel and spaced upper and lower end walls formed with respective upper and lower coaxial holes, a supply spool having a core ring and sandwiched between the end walls coaxial with the holes, a takeup spool, and holding formations on the body releasably securing the takeup spool underneath the lower end wall coaxial with the holes and supply spool so that the spools axially flank the lower end wall. A guide extends parallel to the hole axis through the lower wall and the guide, supply spool, and body are made of substantially the same material. A supply of tape has an outer end fixed to the takeup spool and an inner end and forms a loop having an upper leg engaging the guide between the end walls and a lower leg engaging the guide below the lower end wall The inner end of the tape is releasably secured to the supply spool so it can be separated therefrom with very little force, and a pair of spaced arms unitarily formed with the body hold the loop.
