Abstract: A package has a "push-pull" type dispensing closure either threadably engaged with or in press-fit engagement with the container mouth. The closure includes an outer skirt that is pliable and inwardly deformable when squeezed and a dispenser plug member selectively positionable to seal or unseal a dispensing orifice. The container has a mouth and a shoulder below the mouth which slants upwardly and inwardly. When the outer skirt of the closure is squeezed inwardly, the lower skirt edge engages the shoulder causing an upward camming of the closure, whereby the plug member unseals the dispensing orifice.

Abstract: An all-plastic, hinged, tamper-evidencing closure includes an upper closure surface or top with a hinge formed therein. The hinge may be a straight line, or curved or arcuate so as to provide a snap-action for opening and closing. The closure includes a peripherally depending skirt which has structure for removably retaining the closure on a container, such as a snap head or threads. Additionally, the skirt includes tamper-evidencing structure. The closure top surface may be planar, concave or convex, or it may be initially planar, but when subject to vacuum or pressure it becomes concave or convex, respectively. This latter feature provide a visual indicator that the vacuum seal or pressure seal of the container is intact.

Abstract: A snap-on closure for wide mouth containers has an integral hinged lid which can be lifted, as by the thumb, to provide access for spooning contents out of the mouth. The lid closes on a top flange which is presented by either the closure or the container. The closure has a skirt and snaps onto the container below the top flange or to an attachment bead on the container.

Abstract: A closure for a container has a skirt with a frangibly attached tamper indicating band having a band retaining element in the form of a conical hoop. The hoop is hinged to the band by arcuate hinges which are spaced by ports along the hinge line, the ports extending part way toward but not to the distal edge of the hoop. The band is connected to the skirt along a circumferential score line. Another line of weakness, generally parallel to the axis of the closure, extends across the width of the band from the circumferential score line downwardly to the hinge line between the hoop and the tamper evidencing band, and the hoop is split or separated from the hinge line, inwardly to its distal edge. The hoop is under hoop stress in its upfolded configuration and that stress causes the band to break and spring open when the closure is removed from a container, thereby providing more visible evidence of such removal and facilitating resealing.

Abstract: A closure is provided with channels through which wash water can be injected to wash out food particles between the threads of a container after the closure has been applied and sealed. In a composite closure embodiment, a lid or insert disk is received in an annular shell beneath an overhanging top lip of the shell. Water wash channels are provided on the undersurface of the top lip, and extend from the inner edge of the lip outwardly past the edge of the disk. One or more stops on the underside of the top lip prevent the channels from being closed, as by over-tightening. The wash channels extend outwardly past the stop, and communicate with a spiral channel in the threaded region of the shell, which in turn communicates with an outlet. A water jet directed onto the lid of the closure flows through the wash channels outwardly over the edge of the lid and downwardly into the threaded region, to an outlet.

Abstract: A pressure venting package for foods has a container with both top and side seal areas, and a closure which can accept two different types of insert disks, one for packaging oxygen sensitive (meat) products and the other for packaging non-oxygen sensitive (non-meat) products. The insert disk used for meat products has a gasket of low oxygen permeability and forms a seal with both the top and side seal areas of the container; whereas the insert disk used for non-meat food products forms only a top seal.

Abstract: A closure for a container has a tamper indicating band with a band retainer in the form of an apertured flap or hoop which is hinged to the lower edge of the band. A series of windows open through the retainer, extending toward but not to its distal edge. As the retainer is turned inside out from its as-molded position to its use position, its distal and/or hinged edges deform to relieve compression and permit the retainer to be inverted by direct downward pushing force. As a result of the deformation, the retainer in its use position may, depending on the number and size of windows, have an advantageous polygonal peripheral shape rather than a circular shape.

Abstract: Apparatus for applying closures to containers held by grippers and moving in a row on a conveyor. The closures are fed from a supply into pockets on a star wheel which delivers them to closure carriers mounted to an applicator wheel which rotates in a plane parallel to and above the closure path of movement, about an axis perpendicular to that of the star wheel. Rotation of the closures carried by the carriers on the applicator wheel is synchronized with the rate of movement of the containers, and the closures are brought into converging alignment with the containers. The applicator wheel has optional means for pressing the closure partially or wholly to a final applied position on the containers, and/or for rotating them while still carried by the carriers to desired torque level.

Abstract: Inadvertent rupture of frangible tamper evidencing means during application of threaded closures is reduced by axially pressing the closure partially onto the container, without rotating the closure, until a downwardly tapered retaining means on the closure is engaged by an upwardly tapered locking rib around the container finish. This engagement centers and positions the closure so that the axis of the closure is aligned with the container axis. The closure is held in alignment to prevent cocking or misengagement of the threads until the closure is thereafter turned to tighten it on the container.

Abstract: Disclosed is a package having a closure which provides child resistance with optional easy opening and closing features. The closure is permanently but rotatably attached to the container finish, and is held on the container by snap engagement with the container or with an adapter which is separately attached to the container. The closure has a depending skirt which encircles a latching flange on the container or on the adaptor. A hinged lid on the closure has a latch which is latchable beneath the latching flange only if the closure is turned to a position such that the latch is aligned with a latch slot in the latching flange. Rotation of the closure relative to the slot, once the latch has been engaged through the slot, locks the lid against opening.

Abstract: A closure having an axially movable insert disk which is lifted by a bead around the inside of the closure shell to open a sealed container. When the closure is in sealing position on the container, the lifting bead lies below the top of external threading on the container, and at the top of cooperating internal threading of the closure skirt. The bead has an inside diameter greater than that of the closure threading, and can move upwardly past the external threading on the container. The overall heights of the closure and the container finish can thereby be reduced and less material used.
