Abstract
Abstract An apparatus adapted to be mounted upon an aerial projectile for releasing a drug within the body of a game animal includes a first cylindrical member having first and second axially spaced flanges, and a second cylindrical member concentrically disposed around the first cylindrical member so as to form an annular chamber for the storage of the drug. The apparatus exhibits complete axial symmetry so as to enhance the aerodynamic stability of the projectile during flight.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
267 words
An apparatus for administering a substance beneath the surface of a target and adapted for use with an aerial projectile having a shaft, said apparatus comprising: a first cylindrical member having a first axial end portion and a second axial end portion; a first annular peripheral flange formed on said first axial end portion of said first cylindrical member and projecting radially outwardly therefrom; a second annular peripheral flange formed on said second axial end portion of said first cylindrical member and projecting radially outwardly therefrom; a third annular flange formed on said first axial end portion of said first cylindrical member and projecting radially inwardly therefrom to form a pocket within said first cylindrical member for receiving said shaft; sealing means provided around an outer circumferential edge portion of each of said first and said second annular peripheral flanges; a second cylindrical member having a first axial end portion and a second axial end portion and concentrically disposed around said first cylindrical member; and an annular peripheral flange formed on said second axial end portion of said second cylindrical member, wherein said first cylindrical member and said second cylindrical member define therebetween an annular chamber axially bounded within said first and second annular peripheral flanges formed on said first cylindrical member for storage of said substance, and wherein said peripheral flange formed on said second axial end portion of said second cylindrical member comprises an inner annular chamfered surface portion defining a funnel shaped region converging inwardly toward a center portion of said second cylindrical member for facilitating loading of said substance within said annular chamber.
Claim 2
Independent Claim
267 words
An apparatus for administering a substance beneath the surface of a target and adapted for use with an aerial projectile having a shaft, said apparatus comprising: a first cylindrical member having a first axial end portion and a second axial end portion; a first annular peripheral flange formed on said first axial end portion of said first cylindrical member and projecting radially outwardly therefrom; a second annular peripheral flange formed on said second axial end portion of said first cylindrical member and projecting radially outwardly therefrom; a third annular flange formed on said first axial end portion of said first cylindrical member and projecting radially inwardly therefrom to form a pocket within said first cylindrical member for receiving said shaft; sealing means provided around an outer circumferential edge portion of each of said first and said second annular peripheral flanges; a second cylindrical member having a first axial end portion and a second axial end portion and concentrically disposed around said first cylindrical member; and an annular peripheral flange formed on said second axial end portion of said second cylindrical member, wherein said first cylindrical member and said second cylindrical member define therebetween an annular chamber axially bounded within said first and second annular peripheral flanges formed on said first cylindrical member for storage of said substance, and wherein said peripheral flange formed on said second axial end portion of said second cylindrical member comprises an inner annular chamfered surface portion defining a funnel shaped region converging inwardly toward a center portion of said second cylindrical member for facilitating loading of said substance within said annular chamber.
Claim 3
Dependent Claim
32 words
The apparatus of claim 1 wherein each said outer circumferential edge portion comprises an annular groove formed therein and wherein said sealing means comprises an O-ring provided in each said annular groove.
Claim 4
Dependent Claim
21 words
The apparatus of claim 1 wherein said annular peripheral flange formed on said second cylindrical member comprises a frusto-conical cross section.
Claim 5
Dependent Claim
41 words
The apparatus of claim 1 wherein said aerial projectile further comprises an arrowhead having a shank and wherein said third annular flange formed on said first cylindrical member has a bore concentrically formed therein for receiving said shank of said arrowhead.
Claim 6
Dependent Claim
28 words
The apparatus of claim 1 wherein said first cylindrical member is formed from a metal material and wherein said second cylindrical member is formed from a plastic material.
Claim 7
Dependent Claim
22 words
The apparatus of claim 1 wherein said first cylindrical member and said second cylindrical member are each formed from a plastic material.
