Abstract
Abstract This application discloses a method of sonically welding a channel between one of a pair of thermoplastic plates. Ridge means are placed along the sides of the channel. The crests of the ridge means provide a relatively small frictional area which is to be sonically welded adjacent the sides of the channel. The ridge means includes an outer ridge and an inner ridge along the sides of the channel with the outer ridge being higher than the inner ridge. Openings may be provided in either of the plates or both of the plates, which openings are connected with the channel, so that fluid may be circulated into or out of the channel through either or both of the plates. A tube or tubes may be connected with the openings in the plates for guiding the fluid into or out of the channel.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
124 words
In combination, first and second thermoplastic members having sonically weldable substantially flat surfaces sonically welded together, each member having a peripheral side edge, said first member having a fluid conductive channel construction extending to said flat surface of said first member and adjacent said flat surface of said second member, said channel construction being disposed completely inboard of said peripheral side edge of said first member, one of said members having a fluid conductive opening passing therethrough and extending from said channel construction to the outside of said one member, and a sonically welded flat band outboard of and completely surrounding said channel construction to hold said members sonically welded together and seal completely around said channel construction outboard thereof and between said members.
Claim 2
Dependent Claim
124 words
In combination, first and second thermoplastic members having sonically weldable substantially flat surfaces sonically welded together, each member having a peripheral side edge, said first member having a fluid conductive channel construction extending to said flat surface of said first member and adjacent said flat surface of said second member, said channel construction being disposed completely inboard of said peripheral side edge of said first member, one of said members having a fluid conductive opening passing therethrough and extending from said channel construction to the outside of said one member, and a sonically welded flat band outboard of and completely surrounding said channel construction to hold said members sonically welded together and seal completely around said channel construction outboard thereof and between said members.
Claim 3
Dependent Claim
33 words

Claim 4
Dependent Claim
43 words
A combination according to claim 2 in which said flat band has been formed from first and second raised means on one of said members that are respectively outboard of and completely surrounding said channel construction to hold said members sonically welded together.
Claim 5
Dependent Claim
14 words

Claim 6
Dependent Claim
29 words
A combination according to claim 4 in which each of said ridge means includes an outer ridge and an inner ridge outboard of and completely surrounding said channel construction.
Claim 7
Dependent Claim
17 words

Claim 16
Dependent Claim
69 words
A combination according to claim 1 wherein said first member has another substantially flat surface opposed to the first-named flat surface thereof that is sonically welded to said second member with both flat surfaces of said first member extending to said peripheral side edge thereof, said channel construction being provided in said first-named flat surface of said first member to a depth short of said opposed flat surface thereof.
Claim 17
Dependent Claim
