Abstract
Abstract A method for adhesively bonding an at least partially hollow first member to a second member received interiorly of the first member. Adhesive is applied to the second member and allowed to attain a substantially nonflowable condition. The first and second members are positioned such that the first member at least partially overlies the nonflowable adhesive on the second member. The adhesive is reactivated and then cooled to adhesively bond the first and second members together. An adhesive dispenser for applying the adhesive to the second member is also disclosed.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
115 words
A method for adhesively bonding an at least partially hollow first member to a second member received interiorly of the first member, the method of comprising the steps of: (a) applying a moisture curable hot melt adhesive to the second member; (b) allowing the adhesive to attain a substantially nonflowable condition; (c) positioning the first member and the second member such that at least a portion of the second member is received interiorly of the first member whereby at least a portion of the first member at least partially overlies the substantially nonflowable adhesive; (d) reactivating the substantially nonflowable adhesive; and (e) cooling the reactivated adhesive to adhesively bond the first and second members together.
Claim 2
Independent Claim
115 words
A method for adhesively bonding an at least partially hollow first member to a second member received interiorly of the first member, the method of comprising the steps of: (a) applying a moisture curable hot melt adhesive to the second member; (b) allowing the adhesive to attain a substantially nonflowable condition; (c) positioning the first member and the second member such that at least a portion of the second member is received interiorly of the first member whereby at least a portion of the first member at least partially overlies the substantially nonflowable adhesive; (d) reactivating the substantially nonflowable adhesive; and (e) cooling the reactivated adhesive to adhesively bond the first and second members together.
Claim 3
Dependent Claim
22 words
A method according to claim 1 wherein the adhesive is applied to the second member by extrusion, coating, spraying, dipping and rubbing.
Claim 4
Dependent Claim
20 words
A method according to claim 1 wherein the adhesive attains the substantially nonflowable condition by cooling to a solid state.
Claim 5
Dependent Claim
13 words
A method according to claim 1 wherein the adhesive is reactivated by heating.
Claim 6
Dependent Claim
30 words
A method according to claim 1 wherein the moisture curable hot melt adhesive includes an isocyanate terminated polyurethane prepolymer which comprises the reaction product of a diisocyanate and polyhexamethylene adipate.
Claim 7
Dependent Claim
22 words
A method according to claim 1 wherein the second member is substantially circular in cross-section and the first member is circumferentially continuous.
Claim 8
Dependent Claim
28 words
A method according to claim 1 wherein the first member is a resilient hand grip and the second member is the shaft of an item of sports equipment.
Claim 9
Dependent Claim
22 words
