Title: Hypodermic syringe with means for withdrawing residual fluid
Inventor: JONES TIMOTHY ROBERT
IPC: A61M5/315
Filed: 1995-05-04
Abstract: The syringe has a detachably coupled, needle-receiving endpiece 13 located at least partially within the barrel 10 and guide means (20 - 23) mounting the plunger 11 slidably within the barrel to define a fluid chamber. The guide means prevent the plunger from rotating during its travel except in its fully depressed position when rotation of the plunger causes an automatic, slight axial retraction thereof to thereby reduce the pressure in the fluid chamber and draw any residual fluid away from the needle tip. Such retraction may be effected by cooperation of suitably profiled inter-engaging surfaces, e.g. protrusions 34, 35 on the plunger and annular grooves 36, 37 formed on the barrel interior. The plunger may carry a finger 72 which minimises the dead space of unexpelled fluid within the endpiece and a bayonet 32 for rotatable engagement within a channel 33 of the endpiece to enable retraction thereof within the barrel. Means may be provided for preventing re-use. <IMAGE>

Filed: 1996-07-17
Abstract: A cup of plastics material incorporating foaming agent has thin wall portions, namely a base 101, a lower side wall 102 and an upper side wall 103. These portions have their wall thickness determined by mould part gap. The cup also has thick wall portions, namely the corner 104, the band 105 and the rim 106, in which foaming occurs after mould opening so that the wall thickness is increased beyond that provided by the mould. The wall portions, including the portion that thickens after mould opening, are formed in first and second gap portions in the mould. The mould part gap of the first and second gap portions is constant from one to the other. The gap portions are differentially cooled (see figure 8) so that plastic material in the first gap portions solidify to form the thin wall portions whilst allowing the material in the second gap portions, before it has substantially solidified, to expand by foaming to form the thick wall portions.
