A tamper-evident closure for containers includes a closure shell having a top surface and a depending skirt. The top surface defines a first aperture therethrough and a frangible portion. The skirt defines an open lower end for engaging a container. A tamper-evident tearable member overlies the top surface of the closure shell and defines a second aperture overlying the first aperture. A removable closure cap overlies the top surface of the closure shell and the tearable member. The closure cap has an annular ring projecting downwardly from an underside of the closure cap and extending through the first and second apertures. The annular ring attaches to an underside of the frangible portion. At least partial removal of the closure cap from the top surface of the closure shell peels the frangible portion away from the top surface of the closure shell along the scoring, and tears the tamper-evident member.

Tamper evident closure for containers

A tamper-evident closure () for containers includes a closure shell () having a top surface () and a depending skirt (). The top surface defines a first aperture () therethrough and a frangible portion (). The skirt defines an open lower end () for engaging a container. A tamper-evident tearable member () overlies the top surface of the closure shell and defines a second aperture () overlying the first aperture. A removable closure cap () overlies the top surface of the closure shell and the tearable member. The closure cap has an annular ring () projecting downwardly from an under-side of the closure cap and extending through the first and second apertures. The annular ring attaches to an underside of the frangible portion. At least partial removal of the closure cap from the top surface of the closure shell peels the frangible portion away from the top surface of the closure shell along the scoring, and tears the tamper-evident member.

A plunger tip for being located on a distal end of a syringe plunger and for sliding sealed engagement with an interior surface of a syringe barrel includes a core constructed of a generally rigid material. The core has a first end for being secured to the plunger, a second end and an endless sidewall between the first and second ends. An elastomeric sleeve at least partially surrounds the endless sidewall of the core.

Dual material plunger tip for use with a syringe

A syringe safety device coupling between a vial and a syringe, including a tubular connector having a first axial end receiving the vial and a second, opposing axial end releasably receiving a syringe. The tubular connector encloses a sliding joint having opposing open axial ends and a passageway between the ends. A first sliding joint end is adapted to engage a syringe needle. A second sliding joint end is configured to releasably engage a needle receiver. The syringe is releasably removable from the sliding joint after fluid coupling with the vial through the sliding joint, without removal of the needle or the sliding joint from the connector, which captures the needle with the sliding joint in the connector. The first end of a joint includes a receiver, adapted to releasably receive a removable syringe needle, and a mount, adapted to releasably receive a releasable needle receiver of a syringe.
