Abstract:
A plastic closure includes a shell having a base wall with a skirt for securement to a container finish and a lip that extends radially inwardly from the skirt at a position adjacent to and spaced from the base wall. A liner is compression molded in situ against the base wall, and between the base wall and the lip. The lip has a plurality of circumferentially spaced passages that extend through the lip for venting air during compression molding of the liner.
Abstract:
A dispensing closure includes a base having a lid integrally connected to the base by a hinge. The base has a deck with a central portion, a dispensing opening in the in the central portion, and a peripheral portion surrounding the central portion. The peripheral portion includes a raised wall partially surrounding the central portion, and having a greatest height adjacent to the hinge and decreasing in height around the central portion. The wall has an inner surface that blends with the central portion of the deck to form a concave channel surrounding the central portion of the deck. The channel surface has a base that is angled with respect to the peripheral portion down and away from the raised wall.
Abstract:
A child-resistant package includes a container having a finish with an open end, external thread, stop lug projecting radially outwardly from the finish, and a closure having a base wall, a skirt with internal thread for engagement with the thread on the container finish, spring element and pair of internal lugs on the skirt and extending radially inwardly from the skirt. Each pair of internal lugs includes a first lug that cooperates with the stop lug on the container finish to prevent unthreading of the closure from the finish absent pressure on the closure against the spring element to push the first lug beneath the corresponding stop lug on the container finish, and a second lug circumferentially spaced from the first lug that cooperates with the stop lug to prevent over tightening of the closure on the finish.
Abstract:
A child-resistant dispensing closure includes a base having a deck with a dispensing opening, a peripheral skirt extending from the deck, and an inner wall extending from the deck for securing the closure to a container. An axial passage extends from the deck between the peripheral skirt and the inner wall, and opens radially outwardly through the peripheral skirt. A pair of spaced ledges are disposed in the axial passage. A lid is molded integrally with the base and is coupled by a hinge to the base so as to be pivotable between a closed position overlying the deck and an open position spaced from the deck. The lid has a latch arm that resiliently extends from a periphery of the lid. The latch arm has a pair of oppositely extending tabs for engagement with the ledges to lock the lid in the closed position. The latch arm is directly manually engageable by a user from a radial direction external to the closure to pivot the latch arm radially inwardly within the passage and release the tabs from the ledges so that the lid can be pivoted toward the open position drawing the latch arm out of the axial passage.
Abstract:
A child-resistant closure includes a base, and a lid integrally molded and coupled to the base by a hinge. The lid has a latch arm resiliently extending from a periphery opposite the hinge and having oppositely extending tabs adjacent to a free end of the latch arm. The base has an external recess for receiving the latch arm and spaced ledges in the recess for engagement by the tabs to lock the lid in a closed position. The latch arm is engageable by a user to pivot the latch arm radially inwardly within the passage and release the tabs from the ledges so the lid can be pivoted toward an open position. The tabs and the ledges are recessed radially inwardly from the outer surface of the latch arm in the closed position of the lid with the tabs engaged beneath the ledges.
Abstract:
An apparatus for inverting the stop flange on a tamper-indicating closure, from an axially outwardly oriented position as molded to an axially inwardly oriented position for use, includes a support base for supporting the closure such that the stop flange as molded is spaced from and oriented away from the support base. A pedestal is movably carried by the support base at a position spaced from the support base. A locator ring is carried by the pedestal and movable with the pedestal to engage the stop flange on a closure carried by the support base and to bend the stop flange radially inwardly. An inversion ring moves through the locator ring to engage and invert the stop flange that is bent radially inwardly by the locator ring.
Abstract:
A tamper-indicating closure for a beverage package includes a base wall having a peripheral skirt with at least one internal thread for securing the closure to a container. A tamper-indicating band is frangibly connected to an edge of the skirt, and a stop flange extends axially and radially from an edge of the band for abutment with a stop bead on the container finish. A plurality of circumferentially spaced drain openings extend axially through the juncture of the band and the flange. A plurality of circumferentially spaced channels extend axially through the internal thread on the closure skirt, with at least some of the channels being axially aligned with the drain openings. The stop bead on the container is in the form of a plurality of circumferentially spaced bead segments separated from each other by circumferential gaps. Liquid product may readily drain from between the container finish and the closure skirt through the axial channels in the closure thread, through the drain openings at the juncture of the closure flange and band, and through the gaps between the stop bead segments on the container finish. The container finish may also have a support flange with drain channels or slots aligned with the gaps in the bead.
Abstract:
A machine for compression molding plastic articles includes a turret constructed for rotation around a vertical axis. A first array of compression molds and a second array of compression molds are mounted on the turret for movement through respective first and second mold paths as the turret rotates around the vertical turret axis. A first mold charge placement mechanism is disposed adjacent to the first path for placing mold charges into molds of the first array in sequence as the turret rotates. A second mold charge placement mechanism is disposed adjacent to the second path for placing mold charges into molds of the second array in sequence as the turret rotates and independently of the first mechanism. The first and second mold paths may be spaced from each other radially of the turret axis and/or longitudinally of the turret axis.
Abstract:
A dispensing closure, in accordance with one aspect of the present disclosure, includes a closure shell of plastic construction having a skirt for mounting on a container neck finish. An insert of plastic construction different from and more rigid than the shell includes a mid portion mounted to the shell, a base with the skirt for sealing engagement with a container neck finish when the closure is mounted on the neck finish, a tip extending from the mid portion and a through-passage for dispensing product from within the container. An overcap is provided for removable receipt over the tip, and preferably is of one-piece integrally molded construction with the shell and flexibly tethered to the shell. The base of the insert preferably is constructed for sealing engagement with the inside surface of the container neck finish, the end surface of the container neck finish and/or the outside edge of the container neck finish.
