ABSTRACT:
A paint roller is described for use with a replaceable paint-applying cover having a rigid hollow cylindrical core. The roller is designed to eliminate or minimize leakage of paint into the interior of the core which in conventional rollers tends to lead to rapid deterioration of both the roller and the cover. The roller includes two end members which fit inside respective ends of the core. One end member has a fixed annular face against which the core abuts while the other is fitted with a separate end cap which can be adjusted axially to tightly grip the core. A snap-fit closure is used to lock the end cap in an adjusted position.
