Abstract: Anionic polyelectrolytes are used as binding agents to reduce the solubility of cationic antimicrobial polyelectrolytes. Ionic attraction between the anionic stabilizing polyelectrolytes and the antimicrobial cationic polyelectrolytes results in formation of a polyelectrolyte complex (PEC). A treatment liquid comprising a stable colloid, suspension, dispersion, solution, coacervate, or emulsion of the PEC in an aqueous carrier is used to treat an article, thus coating, infiltrating, or infusing the PEC onto or into the article. Subsequent drying results in an antimicrobial article wherein the PEC is bound to the article and is significantly less prone, relative to either of the component polyelectrolytes, to being washed, leached, leaked, extracted, or migrated from the antimicrobial article during use, or when exposed to aqueous fluids or solvents.

Abstract: A venting cap liner used in a pressurized container closure arrangement. The cap liner includes a multi-layer sandwich structure having a first layer and a generally flat resilient intermediate layer. The layers include at least one perforation extending through the layers to enable gas flow therethrough. The first layer has a first surface including at least one channel extending from one edge of the first layer to another edge of the first layer. The intermediate layer is responsive to a gas pressure level in the container such that, at a first selected pressure level, the perforation extending through said second layer opens to allow gas to flow through the perforation and at a second selected pressure level, the intermediate layer expands to close the perforation thereby resisting gas flow.

Abstract: A container and closure assembly whereby a pull tab sufficiently narrow in width is secured to the interior of the closure, thereby preventing the closure from becoming loosened or displaced, yet when sufficient torque is applied by the consumer to open the closure and remove it from the container the narrow pull tab is disengaged from its seal to the interior of the closure, yet having the liner over the mouth of the closure remains intact and undamaged, thus preventing any contamination of the container content.

Abstract: A molded, back-off resistant closure for use with an associated container having a neck portion and at least one outwardly projecting ratchet formation includes a generally circular top wall portion and a skirt portion depending from the top wall portion. The skirt includes an inner wall and an outer wall and defines a lower wall portion. The skirt terminates in an edge and includes a thread formation formed in the inner wall for matingly engaging the neck portion of the container. The closure includes a plurality of lugs recessed from the edge and extending radially inwardly from the lower wall and longitudinally along the lower wall portion a distance so as to not touch the edge. The lugs extend outwardly and downwardly such that at least one of the lugs can engage the at least one outwardly projecting ratchet formation on the container neck portion when the container and closure are engaged with one another.

Abstract: A liner for use with a threaded closure cap is formed of a relatively thin, flexible material having a central portion configured for placement in the cap abutting a top wall thereof. The liner has at least one tab extending therefrom. The tab has a leading edge portion that is formed so as to define an angle relative to a tangent line adjacent to a juncture of the tab and the central portion. The angle of the tab is configured to be the same as the angle of the threads in the closure cap so that the tab rests fully against the threads prior to application of the closure to an associated container.

Abstract: A venting closure for use with an associated container includes a closure cap having a circular top wall portion and a depending annular skirt portion. The closure is used with a pressurized container having a threaded neck portion defining a land surface at the top thereof. The closure includes a liner therein adjacent and in spaced relation to the top wall, which liner is positioned between the top wall portion and the land surface and defines a pressure release region with the top wall portion. The top wall portion includes an outwardly extending annular bead-like protecting element having a depending inner wall and a contiguous outer wall. The inner wall is oriented generally transverse to a top wall plane. A flexible portion having a piercing element extending inwardly therefrom toward the liner is positioned centrally of the annular protecting bead and is movable so that piercing element contacts and fractures the liner to release pressure from the container.

Abstract: An inner seal for sealing containers by heat induction, especially when the inner seal may be in contact with the contents of the container during sealing. The inner seal includes a metallic foil layer which heats up almost instantaneously, and a foam layer which thermally insulates the foil layer from the contents of the container which may be in contact with the inner seal. The foam layer is compressed, and is consequently a poorer thermal insulator, where it contacts the land area of the neck of the container to which it is being sealed.

Abstract: A container closure system having a closure cap with a cover and a depending skirt with container engaging threads and a projecting post at the center of the underside of the closure cover. The system also includes a perforated fitment having a disk-like membrane with a plurality of apertures distributed across the membrane and an aperture of the plurality of apertures located at the center of the membrane for receiving the post. The fitment further includes a lip at the outer edge of the membrane for frictionally engaging a container at its rim when the system is applied to the container.

Abstract: A closure having an inner retaining area for receiving a closure liner. The liner circumferentially contacts the land surface of the container to cover the mouth of the container upon application of the closure to the container. A well, formed around the outer peripheral edge on the inside of the closure is dimensioned to receive the land surface of the closure. The well includes an upper surface having integrally depending flexible teeth. The walls of the well together with the teeth provide a directional force against the liner causing the liner to wrap around the land surface to increase the amount of liner to land surface contact and thereby counter the effects of irregularities on the land surface. The teeth also provide a localized compression force down against the liner to further increase the sealing contact between the liner and the land surface.
