Abstract:
A child-resistant package includes a container having an open mouth, a conical external surface around the open mouth that widens away from the mouth and a wall extending from the conical external surface. A closure has a base wall, and a peripheral skirt having a first portion adjacent to the base wall and a second portion removably connected to the first portion. An annular first wall extends from the base wall at a position radially inward from the skirt for spring/sealing engagement with the conical external surface of the container. A second wall extends from the base wall at a position radially inward from the first wall and, preferably, at an outward conical angle to the base wall. The second portion of the skirt and the wall on the container have interlocking elements that resist removal of the closure from the container in a child-resistant mode of operation absent a force against the first wall to disengage the interlocking elements. The second portion of the skirt is frangibly removable from the first portion to remove the interlocking elements from the skirt so that the closure is securable to the container in a non-child-resistant mode of operation with the second wall received by snap-fit within the container mouth.
Abstract:
A container includes a container base and a lid interconnected by a hinge and being of one-piece integrally molded plastic construction. The container base is of generally rectangular outline having a back wall to which the hinge is connected, a front wall, opposite sidewalls and an open end. The front wall is connected to the back wall opposite the open end by a continuously curving end wall so that the front wall, the back wall and the continuously curving end wall form a continuous surface for application of a label to the front wall, the back wall and the continuously curving end wall. The sidewalls have flat coplanar edges opposite the open end to permit the container to be stood on end with the open end facing upwardly. The container preferably includes a child-resistant latch having a first latch element on the lid opposite the hinge and a second latch element on the front wall of the container ban adjacent to the open end and opposite the hinge. A continuous label may be applied to the front wall, the back wall and the continuously curving end wall of the container.
Abstract:
A method and apparatus for injection molding an article including a radially extending child resistant feature. Finish block halves are provided that include a pocket and that are closable together to form a neck-finish mold cavity. Mold body halves are provided that include a core portion and that are closable together to form a body mold cavity. The core portion is advanceable toward the pocket to cooperate therewith to define a cavity for forming the child resistant feature. The core portion may be integrally formed into one or more of the mold body halves, or may be separately mounted and relatively movable with respect thereto.
Abstract:
A child-resistant closure and container package includes a container having an open end surrounded by a cylindrical wall with a central axis, a plurality of circumferentially spaced projections extending radially outwardly from an outer surface of the wall adjacent to the open end, notches on undersides of the projections, and a plurality of circumferentially spaced flexible resilient spring elements extending radially outwardly from the outer surface of the cylindrical wall and angularly disposed between the projections. A closure includes a base wall, a cylindrical skirt extending from the base wall to an axial edge spaced from the base wall, a plurality of circumferentially spaced lugs extending radially inwardly from the skirt, and a circumferentially continuous annular wall extending axially from the base wall coaxially with and spaced radially inwardly from the skirt. The axial edge of the skirt is adapted for axial edge abutment with the spring elements on the container to urge the lugs axially into the notches, with the annular wall being in internal plug-sealing engagement with the open end of the container. Removal of the closure requires axial movement of the closure against the spring elements and rotation of the closure to move the lugs out of the notches and clear the projections.
Abstract:
A dispensing closure has an integral measuring device and spoon applicator. The closure has an internal thread on a skirt for fitting onto a container finish. The closure has a tubular measuring device depending from the base wall within the radial confines of the skirt and ending at a spoon applicator for ease of oral administration.
Abstract:
A child-resistant package includes a container having an end with an open mouth surrounded by a container wall having a central axis. An external ledge extends around the container wall at a position spaced from the open mouth. The ledge has an axially facing surface that adjoins a radially outwardly facing surface of the container wall, and closure securement structure on the ledge including at least one pocket. A closure includes a base wall, a peripheral skirt coupled to the base wall, at least one internal lug on the skirt for receipt in the at least one pocket on the container, and an annular wall that extends from the base wall for plug-sealing receipt within the container mouth when the skirt is received over the end of the container. At least one spring element extends from the base wall of the closure adjacent to the skirt radially inwardly and axially within the skirt. The spring element is adapted to engage the axially facing surface of the ledge and to slide radially inwardly along the ledge surface as the closure lug is moved into the pocket on the container to bias the lug into the pocket. The radially outwardly facing surface of the container wall adjacent to the ledge axially facing surface functions as a stop to prevent over-compression of the spring element, and to prevent engagement of the spring element with the annular wall on the closure and thereby affect the plug seal function of the annular wall.
Abstract:
A child-resistant package includes a housing having an internal volume for holding items to be dispensed, a cylindrical neck, an end wall on the neck and a dispensing opening in the end wall. A closure has an end wall with a dispensing opening and a skirt. One of the skirt and the neck, preferably the neck, has a channel and the other of the skirt and the neck, preferably the skirt, has a bead for receipt in the channel such that the closure is rotatable on the neck for selectively aligning the dispensing openings to dispense items from within the housing. A child resistance mechanism between the closure and the neck resists rotation of the closure on the neck. The end wall of the closure preferably includes a dosage window, and a disk preferably is disposed between the closure and the end wall of the neck having dosage indicia viewable through the dosage window. A ratchet drive preferably is disposed among the closure, the housing and the disk for indexing the disk upon each rotation of the closure on the neck to align the dispensing openings, but to resist rotation of the disk upon rotation of the closure in the opposite direction.
Abstract:
A method of making an identifiable article such as a container or container preform. A molded plastic container or container preform is provided that includes a wall having at least one layer of matrix resin and at least one layer of barrier resin that is blended with an additive. The wall has at least one localized portion of predetermined geometry in which the barrier layer is thicker than surrounding portions of the wall, and within which the additive is discernable under visible or UV light so as to provide a means to prevent use of counterfeit containers.
Abstract:
A package having child-resistant and non-child-resistant modes of operation includes a container having a neck finish with an open end, an external surface surrounding the open end and at least one external first engagement element spaced from the open end. A closure has a base portion, a skirt extending from the base portion, and at least one internal second engagement element on the skirt for engagement with the external first engagement element on the container neck finish in a child-resistant mode of operation. The skirt containing the second engagement element is severable from the base portion of the closure to convert the closure from a child-resistant mode of operation to a non-child-resistant mode of operation. A first annular element within the skirt is disposed for engagement with the external surface on the container neck finish to seal the package in the child-resistant mode of operation. A second annular element is disposed radially inwardly from the first annular element for engagement with the open mouth of the container neck finish to secure the closure to the container neck finish in the non-child-resistant mode of operation.
Abstract:
A closure includes a skirt and internal lugs on the skirt. The skirt has an undulating circumferential contour that includes alternate outwardly convex and outwardly concave portions, with the internal lugs being disposed within the outwardly concave portions of the skirt. The skirt preferably is sufficiently flexible to allow the outwardly concave portions of the skirt to assume an outwardly convex geometry as a result of outward pressure on the internal lugs during demolding of the closure. The closure thus may be simply axially stripped from the mold core during the demolding operation without requiring movement of portions of the mold core to clear a path for travel of the lugs. The lugs preferably are shaped as an inverted U that opens toward a free edge of the skirt, further to facilitate demolding of the closure.
