US 6,282,985 B1 · Multi-function bottle opener

Abstract

An improved multi-function bottle opener includes a hollow body (10), a piston (20), a helical coil (30), and a collar (40). The hollow body has a bore (12), a counter bore (14), a shoulder (18) formed between the bore (12) and the counter bore (14), and two opposed trackways (16) defined in an inner wall defining the bore (12). Each trackway (16) is formed as a loop and includes a longitudinal portion (166) and a helical portion (168). The piston (20) is slidably received in the bore (12), and has two opposed lugs (22) which are slidably received in a respective one of the trackways (16). The helical coil (30) is secured to a bottom face of the piston (20). The collar (40) is slidably received in the counterbore (14), and is reciprocatingly urged between the shoulder (18) and an inner flange (142) formed at a bottom of the counterbore (14). As the helical coil (30) turns, it and the piston (20) are drawn down the longitudinal portion (166) to a bottom limit thereof, whereafter the lugs (22) enter the helical portions (168) and the piston (20) and helical coils (30) accordingly return to a top limit of the longitudinal portion (166), whereby the cork is removed from the bottle despite the bottle opener remaining mated with the bottle, and the body (10) having been continually rotated in a single direction.

Dependent claims

An improved multi-function bottle opener comprising:

a hollow body including a bore, a counter bore in communication with the bore, a shoulder formed between the bore and counter bore, a guidance device defining at least one loop in a wall defining the bore, and a retention element formed in the counter bore;
a piston received in the bore and reciprocally movable between upper and lower limits of the bore, and including a follower device traveling along the guidance device;
a collar slidingly received in the counter bore and reciprocating between the shoulder and the retention element;
a corkscrew with a first end secured to the piston and a pointed second end;
a resilient element disposed between the collar and the shoulder;
wherein when the collar of the improved bottle opener is mated with a neck of a bottle to remove a cork therefrom, the hollow body is continuously rotated in one direction such that the piston is linearly guided by the guidance device down the bore as the corkscrew penetrates the cork, and then is rotationally guided by the guidance device up the bore, whereby the cork is removed from the neck of the bottle while the body is still mated with the bottle.
