Abstract
A hermetically sealed package is provided that is suitable for dispensing a material into a body cavity. The package includes a container having a dispensing nozzle surrounded by a seamless sleeve that prevents contact between the container's dispensing orifice and body tissue without impeding material flow from the container. Preferably the nozzle is provided with a twist-off closure constituted by a cap joined to the dispensing nozzle by a frangible web that surrounds the dispensing orifice.
