Abstract
A hopper assembly for a hopper-type texture spray gun applicator apparatus; the hopper assembly including a hopper reservoir housing such as an elongated tubular housing having a specific length to diameter (L/D) ratio. The hopper assembly is adapted for being removably connected to a spraying apparatus such as a spray gun which is coupled to a pressure source such as an air compressor for atomizing texture material contained in the hopper reservoir housing of the hopper assembly. The hopper assembly, the spray gun and the air pressure source may be used together to comprise a hopper-type texture spray gun applicator adapted for spraying texture material on work surfaces such as interior walls, floors and ceilings of a building.

A hopper assembly adapted for being removably connected to a spraying apparatus, said hopper assembly comprising:
- (a) a hopper reservoir housing;
- wherein the hopper reservoir housing comprises an elongated tubular housing member having a length to diameter (L/D) ratio of from about 0.25 L/D ratio to about 36 L/D ratio;
- and wherein the elongated tubular housing member includes a feed orifice at a distal end of the elongated tubular housing member and a discharge orifice at a proximal end of the elongated tubular housing member;
- said proximal end of the elongated tubular housing member adapted to being removably attached to a spraying apparatus;
- (b) a means for removably attaching said hopper reservoir housing to the spraying apparatus;
- and
- (c) optionally, a re-closable cover means adapted to being removably attached to the feed opening at the distal end of the elongated tubular housing member.
