Abstract

298,180. Dental Manufacturing Co., Ltd., and Edwards, H. A. July 5, 1927. Sytringes.-In hypodermic syringes in which an ampoule containing the medicament is punctured on insertion in the barrel 5, the plunger 2 passes through a plug 3 closing the end 10 of the barrel and a cap 4 on the plunger is secured to the barrel by a bayonet joint 8, 9. A spiral spring 1 is provided between the members 3, 4, the spring abutting against a recessed head 7 of the member 3 and being compressed when the cap 4 is secured in place. The baoynet joint 8, 9 may be replaced by a joint comprising ribs or pins on the member 10 which are made to engage internal recesses on the cap 4 when the cap is positioned and given a half turn, portions of the cap between the recesses being cut away to permit such engagement. According to the Provisional Specification the joint comprises a collar on the member 10 adapted to be sprung into a groove on a semicircular extension of the cap 4, the extension being cut to render it sufficiently resilient.
