There is disclosed a closure which permits the opening of a membrane sealed nutritional or pharmaceutical product container in a single action motion which also maintains a hermetic seal under retort conditions. This closure includes a generally cylindrical side wall having threads along the inner surface thereof and retaining means for cooperative engagement with the lip of a plastic container, and a top having an annular rim portion and a center portion, with the top having a lower surface attached to a heat-sealable barrier able to be secured to the plastic container, with the top also having a center portion removal means. A method is also disclosed for providing a hermetic seal on plastic containers using the closure and plastic container of this invention.

Method of sealing a plastic container

Retortable closure for plastic container

This invention is concerned with a closure which permits the sterile opening of a membrane sealed container in a single-action motion which also maintains a hermetic seal under retort conditions. This closure includes a generally cylindrical side wall having threads along the inner surface thereof, a top with an upper surface having a protective rim extending upwardly therefrom, with the top also having a dome assembly with the protective rim extending above such dome assembly. The dome has a top and bottom surface, with at least one plow member projecting downwardly from the bottom surface of the dome.

Piercing closure

An enteral delivery universal port assembly fabricated from a first portion and a second portion of different materials. The first portion has a generally cylindrical side wall, an annular top surface and a corresponding annular bottom surface. The second portion has a central portion with a peripheral flange extending radially outward therefrom, and an annular portion positionable is superposed adjacent relationship to the annular bottom surface. Extending upwardly from the surface of the central portion are first and second projections, the first projection having a base which is a spikable membrane and the second projection being associated with filter means which allow air to enter the enteral nutritional product container to which the enteral delivery universal port assembly is secured in its operative embodiment.

Closure with filter

A closure containing an internalized microbial filter for use in enteral delivery set assemblies. The closure comprises a generally cylindrical side wall, a planar top surface having first and second projections, the first projection being associated with the spikable membrane while the second projection is associated with a filter and with means to limit air access to the filter. The closure also includes a bottom surface having an aperture which extends through the closure to the top surface thereof with the filter being secured to the bottom surface and extending across the opening of the aperture.
