Abstract
A system for launching confetti into the air is disclosed in which a gas cylinder is connected to a barrel containing confetti through a manually operated on-off valve. In a preferred embodiment of the invention, the valve is a pressure reduction valve, and the confetti comprises stacks of elongated tetragonal-shaped confetti.
Claims8
A confetti launching system comprising:
- (a) a cylinder of compressed gas at high pressure;
- (b) a manually operated on-off valve, said on-off valve having an inlet connected to said cylinder, a valve seat and a movable valve head;
- (c) means for puncturing said cylinder and admitting high pressure gas to said valve inlet;
- (d) an outlet passage connected to said on-off valve;
- (e) a hollow barrel containing at least one stack of elongated tetragonal shaped confetti connected to said outlet passage;
- and
- (f) a manually actuated trigger connected to said valve head to open and close said on-off valve and selectively admit gas into said hollow barrel and eject confetti from said barrel high into the air.

A hand-held confetti launching system comprising:
- (a) a cylinder of compressed gas at high pressure;
- (b) a manually operated on-off valve, said valve including an inlet, an outlet and a valve chamber;
- (c) a valve seat and a movable valve head engaging said valve eat, said valve seat and said valve head positioned in said valve chamber such as to reduce the pressure of said high pressure gas in flowing therethrough;
- (d) said gas cylinder being connected to said valve inlet;
- (e) means for puncturing said cylinder and thereby admitting high pressure gas into said inlet and into said valve chamber;
- (f) a hollow barrel connected to said valve outlet, said hollow barrel containing at least one stack of elongated tetragonal-shaped confetti;
- and
- (g) trigger means connected to said valve head for opening and closing said on-off valve to selectively admit gas at reduced pressure into said barrel and eject said stack of tetragonal-shaped confetti from said barrel.
