Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 236 words
A flavor injector device comprising an elongated hollow needle, a base formation adjacent one end of said needle and comprising finger grip abutments projecting from opposite sides of said needle and having concave surfaces facing towards the remote end of said needle, a bulblike container for liquid flavoring material or the like and means for attaching said container to said base formation in a position in which said container extends outwardly from said base end of said needle, said container being of a size to be engaged by the palm of a hand gripping said finger grip abutments and formed of a resilient material readily collapsed by pressure of a hand gripping said finger grip abutments, said means for attaching said container to said base formation comprising a tubular neck extending from one side of said container and a cylindrical socket in said base formation extending coaxial with the axis of said needle and adapted to receive said neck, and a tubular piercing member extending from the inner end of said socket and coaxial with said socket, said piercing member forming an extension of said hollow needle adapted to project into the neck of said container, the projecting end of said piercing member having a cutting edge for piercing a membrane adapted to close the neck of said container when said neck is inserted into said socket, and means to retain said neck in said socket.
