Method of assembling a glass tube and thermoplastic resin, finger grip and nose sleeve syringe body assembly

Claim 1

THE METHOD OF ASSEMBLY OF A GLASS TUBE, A NON-GLASS FINGER GRIP MEMBER AND A NON-GLASS NOSE-FORMING MEMBER TO FORM A UNITARY PHARMACEUTICAL PACKAGING SUBASSEMBLY, COMPRISING AXIALLY ALIGNING AND EFFECTING RELATIVE AXIAL MOVEMENT OF A GLASS TUBE AND TWO OPPOSING SLEEVES OF THERMOPLASTIC RESIN, ONE OF WHICH SLEEVES HAS A TUBULAR SHEATH SECTION AND A LATERALLY EXTENDING FINGER GRIP THEREIN, AND THE OTHER OF WHICH SLEEVES IS A NOSE-FORMING SLEEVE HAVING A TUBULAR SHEATH SECTION AND A REDUCED DIAMETER DISPENSING SECTION EACH OF SAID SLEEVES BEING DISPOSED WITH ITS SHEATH EXTENDING TOWARD A RESPECTIVE OPEN END OF SAID GLASS TUBE, AND EFFECTING AXIAL MOTION OF EACH OF SAID SLEEVES TOWARD AND RELATIVE TO SAID RESPECTIVE OPEN ENDS AND INTO COAXIAL ENGAGEMENT THEREWITH TO A POINT WHERE SAID SLEEVE SHEATHS EFFECTIVELY ENCOMPASS A SUBSTANTIAL LONGITUDINAL WALL EXTENT AT EACH RESPECTIVE END OF SAID TUBE, AND LIE IN INTIMATE INTERSURFACE CONTIGUITY THEREABOVE, SAID THERMOPLASTIC RESIN SLEEVE SHEATH SECTIONS EACH HAVING AN INTERNAL RELAXED DIAMETER PROOR TO ASSEMBLY AND WHEN AT NORMAL ROOM TEMPERATURES OF APPROXIMATELY 70*F. OF LESS DIAMETER THAN THE EFFECTIVE OUTER DIAMTER OF THE RESPECTIVE END OF SAID GLASS TUBE, AND CAMMING SAID SLEEVE SHEATH SECTIONS TO A LARGER STRETCHFIT AND EFFECTIVE INNER DIAMETER THROUGH SEQUENTIAL INCREMENTAL OUTWARD CAMMING ACTION ON SAID SLEEVE SHEATHS AT EACH SUCCESSIVE INCREMENTAL ZONE OF AXIAL INTERENGAGEMENT BETWEEN EACH OF SAID SLEEVE SHEATH AND THE RESPECTIVE END OF SAID GLASS TUBE, SAID CAMMING ACTION AT EACH END OF SAID GLASS TUBE BEING EFFECTED BY CAMMING INTERACTION BETWEEN A SLOPED ANNULAR CAM SURFACE FORMED ON ONE OF THE INITIALLY INTERFACING ENDS OF SAID TUBE AND SAID THERMOPLASTIC RESIN SLEEVE, HEATING SAID SLEEVES PRIOR TO ASSEMBLY WITH SAID GLASS TUBE, ASSEMBLING SAID SLEEVES AND GLASS TUBE WHILE SAID SLEEVES ARE IN AN ELEVATED TEMPERATURE CONDITION, AND ENABLING COOLING OF SAID SLEEVES IN SITU ON SAID GLASS TUBE.

Claim 2

THE METHOD OF ASSEMBLY OF A GLASS TUBE, A NON-GLASS FINGER GRIP MEMBER AND A NON-GLASS NOSE-FORMING MEMBER TO FORM A UNITARY PHARMACEUTICAL PACKAGING SUBASSEMBLY, COMPRISING AXIALLY ALIGNING AND EFFECTING RELATIVE AXIAL MOVEMENT OF A GLASS TUBE AND TWO OPPOSING SLEEVES OF THERMOPLASTIC RESIN, ONE OF WHICH SLEEVES HAS A TUBULAR SHEATH SECTION AND A LATERALLY EXTENDING FINGER GRIP THEREIN, AND THE OTHER OF WHICH SLEEVES IS A NOSE-FORMING SLEEVE HAVING A TUBULAR SHEATH SECTION AND A REDUCED DIAMETER DISPENSING SECTION EACH OF SAID SLEEVES BEING DISPOSED WITH ITS SHEATH EXTENDING TOWARD A RESPECTIVE OPEN END OF SAID GLASS TUBE, AND EFFECTING AXIAL MOTION OF EACH OF SAID SLEEVES TOWARD AND RELATIVE TO SAID RESPECTIVE OPEN ENDS AND INTO COAXIAL ENGAGEMENT THEREWITH TO A POINT WHERE SAID SLEEVE SHEATHS EFFECTIVELY ENCOMPASS A SUBSTANTIAL LONGITUDINAL WALL EXTENT AT EACH RESPECTIVE END OF SAID TUBE, AND LIE IN INTIMATE INTERSURFACE CONTIGUITY THEREABOVE, SAID THERMOPLASTIC RESIN SLEEVE SHEATH SECTIONS EACH HAVING AN INTERNAL RELAXED DIAMETER PROOR TO ASSEMBLY AND WHEN AT NORMAL ROOM TEMPERATURES OF APPROXIMATELY 70*F. OF LESS DIAMETER THAN THE EFFECTIVE OUTER DIAMTER OF THE RESPECTIVE END OF SAID GLASS TUBE, AND CAMMING SAID SLEEVE SHEATH SECTIONS TO A LARGER STRETCHFIT AND EFFECTIVE INNER DIAMETER THROUGH SEQUENTIAL INCREMENTAL OUTWARD CAMMING ACTION ON SAID SLEEVE SHEATHS AT EACH SUCCESSIVE INCREMENTAL ZONE OF AXIAL INTERENGAGEMENT BETWEEN EACH OF SAID SLEEVE SHEATH AND THE RESPECTIVE END OF SAID GLASS TUBE, SAID CAMMING ACTION AT EACH END OF SAID GLASS TUBE BEING EFFECTED BY CAMMING INTERACTION BETWEEN A SLOPED ANNULAR CAM SURFACE FORMED ON ONE OF THE INITIALLY INTERFACING ENDS OF SAID TUBE AND SAID THERMOPLASTIC RESIN SLEEVE, HEATING SAID SLEEVES PRIOR TO ASSEMBLY WITH SAID GLASS TUBE, ASSEMBLING SAID SLEEVES AND GLASS TUBE WHILE SAID SLEEVES ARE IN AN ELEVATED TEMPERATURE CONDITION, AND ENABLING COOLING OF SAID SLEEVES IN SITU ON SAID GLASS TUBE.
