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 compact (10) securely engaging an edge of a blister card (60) with a multiplicity of items (62) separately packaged thereon. The compact, which is formed from a molded blank (12) of a thermoplastic material, has first and second generally planar members (20, 22) separated from one other by parallel, generally rectangular portions or strips (24, 30) that are defined by three spaced apart fold lines (14, 16, 18). The generally rectangular strips are foldable about the centrally located of the fold lines (14) to overlie one another and to engage an edge of the blister card, and are locked in such overlying positions by engagement of locking posts (26, 28) on one of the strips with recesses (32, 34) on the other of the strips. Opposed ends of the compact have locking tabs (40, 42) that are received in recesses (44, 46) in a closed position of the compact, and these locking tabs must be simultaneously manually engaged to permit the compact to be opened. Further, a front edge of the compact, which extends between its opposed ends, has a latch (48) that must be manually depressed from engagement with a tab (50) by a second hand of a user simultaneously with manual engagement of the locking tabs (50) before the compact can be opened, which, in combination with the locking tabs, imparts child-resistant opening characteristics to the compact.
Abstract:
A child resistant closure having an outer cap and an inner cap each of which has a base wall on a peripheral skirt with sets of lugs on the inner surface of the outer closure member and on the outer surface of the inner closure member which are adapted to be engaged when the members are moved axially toward one another. The outer surface of the inner cap is provided with a plurality of vents to allow for increased evacuation of fluid between the inner and outer cap.
Abstract:
A child-resistant closure includes a plastic inner shell having a base wall with a peripheral skirt, at least one internal thread segment on the peripheral skirt and a plurality of internal lugs on the base wall adjacent to the skirt. A plastic outer shell has a base wall with a peripheral skirt and a plurality of internal L-shaped lugs at a juncture of the base wall and the peripheral skirt. Each of the L-shaped lugs includes a first portion extending radially inwardly along an undersurface of the base wall of the outer shell for engaging the external lugs on the inner shell, and a second portion extending axially along an inner surface of the peripheral skirt of the outer shell for slidably engaging the inner shell and aligning the inner shell within the outer shell. The second portions of the L-shaped lugs preferably have rounded radially inwardly facing surfaces for reduced sliding friction with the skirt of the inner shell.
Abstract:
Containers a retaining member disposed within the container which substantially obstructs the opening of the container are disclosed. In a preferred embodiment, the member enlarges to receive a dispensing instrument that is used to cap the container.

Abstract:
A dispensing valve includes an annular ring of relatively rigid molded plastic construction and a flexible resilient valve element integrally molded with the ring. The ring and the valve element have at least one mechanical interlock to secure the valve element to the ring as the valve element is molded onto the ring. In some embodiments of the disclosure, the mechanical interlock includes openings in an inner periphery of the ring and pegs on the outer periphery of the valve element that are molded into the openings as the valve element is molded onto the ring.
Abstract:
A dispensing package includes a container having a cylindrical neck finish with an open end and at least one internal bead spaced from the open end. A dispensing fitment has a conical inner portion and an outer portion with spaced external beads received by snap fit over the internal bead so that the dispensing fitment is spaced from the open end of the neck finish. The dispensing fitment preferably has an annular V-shaped cross section opening toward the open end of the neck finish, with an outer leg forming the outer portion of the fitment and an inner leg forming the inner portion of the fitment.
Abstract:
A closure includes an outer plastic shell having a base wall, a peripheral skirt with a central axis, a circumferential array of lugs on an underside of the base wall, and a pair of axially spaced internal beads on the skirt spaced from the base wall. An inner plastic shell has a base wall, a peripheral skirt with a central axis, at least one internal thread on the skirt of the inner shell, a circumferential array of lugs on an outer surface of the base wall, and a circumferential bead on an outer surface of the skirt remote from the base wall. The inner shell is positionable within the outer shell in a non-child-resistant first position with the bead on the skirt of the inner shell captured between the beads on the skirt of the outer shell, such that the outer shell is rotatably coupled to the inner shell and the at least one internal thread on the skirt of the inner shell can be threaded onto and off of a container by simple rotation of the outer shell. The inner shell is positionable within the outer shell in a child-resistant second position with the bead on the inner shell skirt spaced from the beads on the outer skirt, such that rotation of the outer shell is imparted to the inner shell by forced engagement of the lugs on the base wall.
Abstract:
A child-resistant closure and container package includes a container having a finish with an external thread and pockets in the thread. A closure has a base wall, a peripheral skirt with an internal thread and lugs on the internal thread for receipt in the pockets, and a spring element on the base wall for engagement with the container finish to bias the closure away from the container finish and resiliently urge the lugs into the pockets. A liner is urged by the spring element into engagement with the container finish. The liner may include a base with metal and plastic layers for induction-welded sealing engagement with the finish such that, upon removal of the closure, the metal and plastic layers remain secured to the finish and the liner base is removed with the closure. The metal and plastic layers may be removed by a user for access to the contents of the container, and the liner base continues to serve as a package seal during use of the package.
