Abstract
Abstract A novel thermoplastic manifold and thermoplastic fluid fittings for the distribution of fluids, such as pressurized carbonated water, has an elongate tubular thermoplastic conduit with a plurality of apertures spaced along its length for receiving the thermoplastic fittings. Each fitting has a spud extending from one end thereof with a sonic energy director around the perimeter thereof. The fittings also include a saddle portion having a pair of arcuate sonic energy directing ridges thereon spaced on each side of the spud. Each fitting is fastened and sealed to the conduit by the sonic welding of the spud perimeter to the conduit aperture perimeter followed by the sonic welding of the saddle to the exterior surface of the tube.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
126 words
A fluid distribution fitting made of a thermoplastic material, for sonically welding to an elongate tube having an internal plenum, to provide for fluid communication between the fitting and the plenum, for forming a fluid distributing manifold, the fluid distribution fitting comprising: an elongated body portion having an interior channel extending therethrough between a first fluid connecting end and a second tube connecting end, the second end having a spud portion integral therewith and extending therefrom for inserting into an aperture extending through the tube, and the spud having a sonic welding energy director consisting of an amount of the thermoplastic meterial integral therewith and extending around the exterior periphery thereof for providing such material for the sonic welding securing of the fitting to the tube.
Claim 2
Dependent Claim
126 words
A fluid distribution fitting made of a thermoplastic material, for sonically welding to an elongate tube having an internal plenum, to provide for fluid communication between the fitting and the plenum, for forming a fluid distributing manifold, the fluid distribution fitting comprising: an elongated body portion having an interior channel extending therethrough between a first fluid connecting end and a second tube connecting end, the second end having a spud portion integral therewith and extending therefrom for inserting into an aperture extending through the tube, and the spud having a sonic welding energy director consisting of an amount of the thermoplastic meterial integral therewith and extending around the exterior periphery thereof for providing such material for the sonic welding securing of the fitting to the tube.
Claim 3
Dependent Claim
88 words
The thermoplastic fluid distribution fitting as defined in claim 1, and further including a saddle, the saddle integral with the body portion and extending outwardly therefrom and around the circumference thereof in a direction transverse to the extension of the spud, and the saddle positioned adjacent the spud in a direction therefrom towards the first end, and the saddle having sonic welding directing means consisting of an amount of the thermoplastic material on a tube facing surface thereof for providing sonic welding of the saddle to the tube.
Claim 4
Dependent Claim
56 words
The thermoplastic fluid distribution fitting as defined in claim 2, and the spud energy director having a peripheral portion with a dirameter slightly greater than the diameter of the tube aperature ad where the spud energy director is positioned on the spud a slight distance from the saddle in a direction away from the first end.
Claim 5
Dependent Claim
21 words
The thermoplastic fluid distribution fitting as defined in claim 2, and the saddle conforming to the exterior dimension of the tube.
Claim 6
Dependent Claim
45 words
The thermoplastic fluid distribution fitting as defined in claim 4, and the saddle having a pair of sonic welding energy directing ridges consisting of a pair of beads of the thermoplastic material extending along the tube facing surface thereof on either side of the spud.
Claim 7
Dependent Claim
32 words
The tehermoplastic fluid distribution fitting as defined in claim 2, and further including a pair of fins integral with the exterior surface of the fitting and extending therealong on opposite sides thereof.
