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 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.
Abstract:
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.
Abstract:
A dispenser closure for attachment to the threaded neck of a container includes spout portion having an annular wall, a shoulder and a depending skirt, the skirt being threaded on an interior surface to lockingly engage the container neck, a spout formation disposed with an area defined by the annular wall and being integral with the spout portion, and a closed-top cap portion having a radially projecting annular shoulder with a depending collar, the collar being threaded on an interior surface to engage a threaded exterior surface of the upper end of the spout portion. A drainage opening in the spout portion facilitates the drainage of the entire contents of the container, and leveling formations facilitate automated assembly of the closure upon the container. Provisions are also disclosed for preventing the exposure of threaded areas of the closure to container contents.
Abstract:
A main body of a rifle accessory mounting apparatus comprises an accessory mounting structure having opposing end portions and a barrel nut engaging structure connected to a first one of the end portions of the accessory mounting structure. An end face of the accessory mounting structure defines a front end face of the main body and an end face of the barrel nut engaging structure defines a rear end face of the main body. A central passage of the main body extends through the accessory mounting structure and the barrel nut engaging structure.
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 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 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.
Abstract:
A dispenser closure for a container includes a body having a generally planar top portion and a peripheral skirt portion depending therefrom to form a cap-like formation, and the top portion is provided with at least one sifter opening, a larger opening for spooning or pouring and a pair of vertically projecting slide guides located thereon in diametrically opposed relation to each other. A substantially planar solid slide plate is also provided and is adapted to slidingly engage the slide guides and to selectively expose either the sifter opening, the larger opening or to cover both the shifter and larger openings.
Abstract:
A closure for use in connection with a capped container includes a seal liner provided with a tab portion, and adapted to seal the mouth of the container, a cap liner adapted to be adhered to the tab portion of the seal liner and releasably retained within the cap so that upon opening of the container as by unscrewing the cap, the cap liner is released from the cap and provides an enlarged gripping surface to enable the consumer to more easily open the container.
