ABSTRACT:
A container is disclosed for dispensing strip material having a light-sensitive layer on one side. A slot through which the strip material can be pulled from a roll of such material within the container has a first lip and a second lip spring resiliently urged toward the first lip. The lips are shaped so that tension in the strip material therebetween produces a resultant force which opposes the resilient force to reduce or eliminate pressure between the light-sensistive layer and the first lip.
