摘要： An assembly (110) for joining at least two tubes (12, 14) is provided by a connector (112), a plurality of linear inserts (20) and a plurality of ring members (30). Each of the tubes (12, 14) has a tube end (16) and an internal conduit (18). The connector (112) has a central portion (115) with an internal conduit (118) having a permanently formed feature (119) therein, and a plurality of arms (117). Each arm (117) extends from the central portion (115) and terminates in an arm end (116), such that there is one arm (117) and one arm end (116) paired with each tube end (16). The internal conduit (118) of the connector (112) extends through the arms (117) to the respective arm ends (116). There is one linear insert (20) for each arm end/tube end pair. A first nipple portion (24a) of each linear insert (20) has an external surface frictionally engaged in an internal surface of the connector internal conduit (118) at the arm end (116) and a second nipple portion (24b) has an external surface frictionally engaged in an internal surface of the tube internal conduit (18) at the tube end (16). One ring member (30) is slidingly received along each tube end (16) or arm end (116) atop one of the linear inserts (20) frictionally engaged therein. The ring member (30) compressively deforms the respective tube end or arm end onto the linear insert (20), joining the connector internal conduit (118) to the tube internal conduit (18) in a leak-free manner.

摘要： The invention encompasses an overmolding process which includes the steps of inserting a flexible one-way valve into a plastic conduit, inserting the conduit with the valve at least partially onto a mold core, radially expanding at least a portion of the mold core from a first radial position to a second extended radial position, molding a polymer over at least a portion of the mold core and the plastic conduit, and radially contracting at least a portion of the mold core from the second extended radial position to essentially the first radial position. The radial expansion and contraction is in response to axial movement of a tapered shaft from a first axial position to a second expanded axial position, the shaft having a first diameter and a second diameter at a terminal end of the shaft, the second diameter being smaller than the first diameter. The axial shaft movement is in response to a controllable supply of a compressible gas which overcomes the biasing force of a spring to move the piston shaft.

摘要： The process of this invention will involve overmolding a thermoplastic or rubbery polymer composition over a thermoplastic hollow tube and a core insert to form a hollow overmolded coupler after the removal of the core insert, the tube entering the coupler at an angle which is less than 90.degree. so as to minimize any freezing of transported water which may reside in the coupler. The combination of the above polymers must satisfy at least two simultaneous conditions. First, the inserted plastic tube must not soften and begin melt flow to the point where it looses structural integrity during the molding processing and second, the overmolded polymer must be capable of forming an essentially leak-proof interface between the coupler and the plastic tube, preferably through either a chemical and/or physical bond between the plastic tube and the overmolded plastic. In one aspect of the invention, the composition of the overmolded polymer will be such that it will be capable of at least some melt fusion with the composition of the plastic tube, thereby maximizing the leak-proof characteristics of the interface between the plastic tube and overmolded plastic, e.g., by having at least a component of the polymer composition of the plastic tube and that of the overmolded polymer being the same or at least sufficiently similar or compatible so as to permit the melt fusion or blending or alloying to occur at least in the interfacial region between the exterior of the plastic tube and the interior region of the overmolded polymer.

The affixation between the heated portion of the crosslinked profile and the second crosslinked polymer passing a hot burst pressure test applicable to an intended end use for said combination at 180° F. without any visible separation between the first and second profiles after the test.

摘要： A mold core is provided for producing an overmolded flexible valve. The mold core comprises a mold body, a piston assembly, a piston retaining means, a collet bit positioning means and at least two collet bits. The mold core has a cylindrical void in a distal end and has a pressure means communicated with the cylindrical void. The piston assembly has a piston head sized and adapted for axial movement in the cylindrical void, with a piston shaft extending axially from the head. The shaft is tapered from a larger first diameter at one end to a smaller second diameter at the other end. The piston retaining means has a bore through it to allow insertion of the piston shaft. Each of the at least two collet bits has an inner cylindrical tapered surface segment, the taper of the surface segment being essentially the same as the taper in the piston shaft, and an outer cylindrical surface segment, sized and adapted to be inserted inside the flexible valve. The at least two collet bits are positioned adjacent to the tapered portion of the shaft. The collet bits are positioned by the collet bit positioning means.

摘要： A polybutylene tubing coupling and method of making that coupling utilizes a male tubular connector element having the same inside diameter as the major extent of the tubing. A coupling element is provided with stop shoulder at one end and a series of annular radially projecting barbs on its outside diameter which are preferably undercut in the direction of the stop shoulder or tubing end. An end of the tube is treated preferably by heating to enable the material to expand and the tubing end is inserted on or slipped over the male element against the stop shoulder. In such position the treated tubing end is mechanically compressed between two semi-circular dies to cause the material of the treated tubing end to flow around the barbs. Thereafter a metal crimp is placed around the tubing end between the stop shoulder and the next adjacent barb, or over the top of one or all barbs. The tubing connection thus formed is then permitted to cool at ambient temperature for approximately 7 days. During such period approximately 1.8% shrinkage will occur in the polybutylene material forming a tight secure tubing connection.
