Abstract: The invention relates to a tamper-indicating bottle closure consisting of a threaded bottle cap and a tamper-indicating band connected thereto by selectively rupturable connectors. The band is provided with at least to radially protruding camming members adapted to move over a retaining lip provided on a bottle, by temporarily radially deforming the band, during closure movement between cap and bottle and to be locked behind the retaining rib during opening movement between cap and bottle at a force exceeding the force of the opening movement.

Abstract: An injection molding machine for the making of barrels of syringes has first and second mold sections which have confronting surfaces and one of which is movable between operative and retracted positions in which the surfaces respectively abut and are spaced apart from each other. The first section has cylindrical bores each of which is open at the respective surface and extends to an end wall adjacent a nozzle with several uniformly distributed orifices which admit heated plasticized material into the bore when the two surfaces abut. The second section has cores each of which extends into a bore in the operative position of the one section to define with the first section a cavity for reception of plasticized material. The first section has coolant-conveying channels which concentrically surround the bores, and the first section has flow restricting ports which connect the discharge ends of the orifices with the respective cavities.
