The present invention relates to a mechanism, system and method for transferring closures. More specifically, the invention relates to a mechanism, system and method for transferring a closure from a first station, preferably a closure chute to a second station, preferably a closure chuck, through the use of a button with a lobe.

Closure transferring mechanism

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.

Venting liner

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.

Narrow pull tab

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.

Back-off resistant closure

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.

Angled tab closure liner

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. The bead inner depending wall and the outer wall define a vent channel in flow communication with the pressure release region, and the inner wall includes at least one vent opening for providing flow communication to vent the gas from the container toward the center of the closure. A method of forming the venting closure includes providing a mold assembly having a female mold member and cooperating, engageable inner and outer male mold cores and a gate insert, assembling the mold to form a mold cavity, engaging the projections with the at least one landing surface, injecting a plastic material into the mold cavity, forming a plurality of vertically oriented vent openings defining horizontally oriented vent paths in the protective bead depending wall, and disassembling the mold and removing the closure.

Closure vent arrangement and forming method therefor

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.

Closure vent arrangement cap

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.

Container closure system

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.

Closure having a wrap-around seal

A closure assembly configured for use with a container having a neck with a land surface at its uppermost end defining a mouth. The closure assembly includes a cap, a liner, and a fitment with a dispensing surface dimensioned to span the mouth of the container. A plurality of liner tabs center the liner in the cap during assembly, and retain the liner and the fitment within the cap prior to placing the cap on a container. One or more tabs may extend through slots in the fitment.

Closure assembly with tabbed liner

A linerless closure cap and fitment assembly configured for use with a container having a neck with an annular lip at its uppermost end defining a mouth. The closure cap and fitment assembly includes a fitment with a dispensing surface having a resealable pour spout and possibly sifting holes dimensioned to span the mouth of the container and a cap with a top panel, an annular skirt and threads for releasable engagement onto the neck of the container. The fitment includes a vertical fin along the sides of the pour spout to dam the product within the container, thereby stopping the product from sifting or 'dusting' out of the closure during shipment in an upright or upside down position.

Linerless closure and fitment assembly

A dispenser closure for attachment to the threaded neck of a container includes a spout portion and a cap portion. The spout portion includes an annular wall, a shoulder and a depending skirt. A spout is integrally formed within the spout portion and is non-concentrically disposed with an area defined by the annular wall. The spout is substantially closed and has an inner channel which is in fluid communication with the interior of the container. The spout terminates at an upper end having an oval aperture and at a lower end at an inclined floor. A drainage opening is also formed in the spout portion and is in fluid communication with the interior of the container. The drainage opening is adjacent the annular wall and extends through the inclined floor and vertically onto the spout. The cap portion has a radially projecting annular shoulder with a depending collar. The collar is threaded on an interior surface to engage a threaded exterior surface of the upper end of the spout portion.

Pour spout and dispenser closure with drainage feature

A closure cap and fitment assembly configured for use with a container having a neck with an annular lip at its uppermost end defining a mouth. The closure cap and fitment assembly includes a fitment with a dispensing surface dimensioned to span the mouth of the container and a liner. The assembly further includes a cap with a top panel, an annular skirt and threads for releasable engagement onto the neck of the container. The inner portion of the cap defines a retaining structure which is designed to retain the fitment and liner within the cap.

Closure cap and fitment assembly

A tamper evident closure assembly comprising a container, a cap and a band portion. The container has a neck with threads and an annular interference ring located axially below the threads and integral with the container finish. The cap is internally threaded, having a top, a peripheral edge integral with the top and an annular skirt integrally depending from the peripheral edge. An annular tamper indicating band is detachably connected to the skirt with a plurality of spaced connectors located between the cap and the band. The band has an annular shoulder on the inside surface thereof. The annular shoulder of the band and the interference ring are configured and arranged relative to each other so that upon the application of twisting torque by the user to remove the cap from the container, the connectors are subjected to a localized vertical force, which severs the connectors sequentially and one or more at a time. After breakage of the connectors, the band remains on the neck of the container as evidence of tampering or removal.
