Abstract: A roller cutter has a partially circular housing having a slit extending in from receiving a cutter wheel, which can be selectively shifted between an extended cutting position and a retracted position enclosed within the housing to protect the cutter wheel cutting edge. A push button operates a latch release to allow shifting between these positions. A slide bar mounting the cutting wheel for shifting movement is itself held in a slot in the housing, but may be released for removal and cleaning. A tangential grip at the top of housing allows convenient stroking for cutting pizza, mincing herbs, etc.

Abstract: A liquid sprayer incorporating an air pump to force pressurized air into the interior of a receptacle. The air pump is operated, by stroking of a cover. The cover has an opening allowing finger access to the plunger of a spray nozzle in one rotated position of the cover, the cover being held in that position. In another rotated position the cover is released for stroking. A piston on the cover projects into a central tubular portion on the cap with valving sealing allowing air to be drawn past the piston and forced into the receptacle. The spray nozzle is offset from the tubular portion and the plunger is accessible through the cover without removing the same.
