Abstract

Abstract A container and method of adhesive bonding of two telescopic container halves wherein each container half has a cylindrical body, the inner container portion being circumferentially loaded to temporarily reduce its diameter and being forced in centered relation to the outer portion into a bead of adhesive laid in the interior of the outer portion to coat the raw edge on the inner portion, the inner portion shearing through the adhesive without wiping it off from the interior of the inner portion and thereafter the hoop stress on the inner portion being relieved so it springs out and squeezes excess bonding material from between the inner and outer portion and thus obtains a thin film adhesive bond with good stress shear characteristics while holding the film in compression therebetween during curing or setting of the adhesive.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 126 words
A container having a pair of axially aligned sections, each having a thin walled metalic body of the same diameter with an end portion defining an open end with a raw edge, one of said sections having a thick annular bead of adhesive material within the end portion thereof, the end portion of the other section being circumferentially precompressed and inserted into said one section an extent axially of the container to bury the edge thereof within said sealing material and cleave a thin band of said material between said end portion, said other section being released from its precompressed state to expand radially and thereby hold said thin band of sealing material between said sections under compression without shearing about the entire circumferential extent thereof.
Claim 2
Dependent Claim 126 words
A container having a pair of axially aligned sections, each having a thin walled metalic body of the same diameter with an end portion defining an open end with a raw edge, one of said sections having a thick annular bead of adhesive material within the end portion thereof, the end portion of the other section being circumferentially precompressed and inserted into said one section an extent axially of the container to bury the edge thereof within said sealing material and cleave a thin band of said material between said end portion, said other section being released from its precompressed state to expand radially and thereby hold said thin band of sealing material between said sections under compression without shearing about the entire circumferential extent thereof.
Claim 3
Dependent Claim 31 words
The invention according to claim 1 and both of said end portions being loaded circumferentially in tension, and said one section being essentially cylindrical after being joined to said other section.
Claim 4
Dependent Claim 23 words
The invention according to claim 1 and said bead of adhesive material being located proximate to said raw edge on said one section.
Claim 5
Dependent Claim 30 words
The invention according to claim 1 and said band of material having a width sufficient to coat the interior and exterior surfaces of the end portion of said other section.
Claim 6
Dependent Claim 13 words
The invention according to claim 1 and said sections being made of aluminum.
Claim 7
Dependent Claim 16 words
The invention according to claim 1 and said sections being between 6 to 11 mils thick.
