Abstract

929,181. Hypodermic syringes. WALL & LEIGH (THERMOPLASTICS) Ltd. Nov. 24, 1960 [Nov. 24, 1959], No. 39755/59. Class 81 (2). A hypodermic syringe which includes a plunger 18 having an integral head and stem, has a barrel 10 at the rear end of which is an increased internal diameter portion 24 which receives the plunger loosely, an internal shoulder 25 being provided between the increased internal diameter portion and the main portion of the barrel. The plunger 18, which is made of thermoplastic material and is hollow, has a stem portion of diameter slightly less than the internal diameter of the main portion of the transparent thermoplastic syringe barrel 10, a thin annular flange 21 which forms the head and is the same diameter as the interior of the barrel and a reduced portion 20 between the stem and the head. The end face of the head is conical to correspond with the conical interior face of the end wall of the barrel. During storage, the plunger head is located in the wider diameter portion 24 of the syringe barrel.
