Abstract: A dispensing valve includes a resiliently flexible mounting portion, a resiliently flexible opening portion disposed radially inwardly of the mounting portion, and a resiliently flexible isolating portion disposed radially between and coupled to the mounting and opening portions. The isolating portion extends both radially outwardly and axially to form a first radial space between the opening and isolating portions, and is spaced radially inwardly of the mounting portion to form a second radial space between the mounting and isolating portions. The opening portion may include one or more slits.

Abstract: A child-resistant dispensing closure for a container may include one or the other or both of a dispensing cover non-removably securable to a container, or an outer cover non-removably securable and rotatable with respect to the inner cover and cooperable with the dispensing cover to render the closure child-resistant. According to another embodiment, an outer cover may include a flange to aid users in pushing and turning the outer cover with their fingers.

Abstract: A container and closure package to provide secure threaded attachment of the closure to the container in a predetermined orientation and inhibits removal of the closure. A container neck finish has an external thread and an external annular ledge or flange therebelow having external locking recesses or notches. A closure includes an inner annular wall adapted for threaded engagement on the neck finish. A closure outer annular skirt wall inhibits tampering access to an intermediate annular locking lug wall disposed concentrically between the inner and outer skirt walls. Locking lugs protrude radially inwardly from the inner periphery of the intermediate annular wall and are disposed for snap receipt into the ledge locking notches as the closure is fully threaded onto the container neck finish.

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 plastic closure for receipt on a container includes a plastic ring having an internal recess adapted to be received by snap fit over an external crown or bead on the container neck finish such that the ring is retained against axial movement on the container neck finish. A plastic lid is coupled by a hinge to the ring, with the ring, the lid and the hinge being of one-piece integrally molded plastic construction. The lid has a skirt that is adapted releasably to be snapped to the ring in a closed position of the lid over the ring. The lid skirt may have an external bead that is adapted to be received by snap-fit within an internal channel on the ring in the closed position of the lid over the ring, and a conical internal surface on the ring may be provided to guide the bead on the lid into the channel on the ring.

Abstract: A dispensing closure includes a closure shell of one-piece integrally molded plastic construction having a base for securement to a container neck finish and a lid coupled by a hinge to the base. The base has a deck, a recess extending across the deck from a point adjacent to the hinge, and a dispensing opening in the recess. The lid has a base portion for receipt in the recess in the closed position of the lid and a tongue at an end of the lid remote from the hinge. A latch on the base in the recess engages the tongue on the lid releasably to hold the lid in the closed position. The latch preferably comprises a snap latch that includes an internal bead on the tongue and an external latch element in the recess over which the internal bead is received in the closed position of the lid. The base preferably includes a ledge in the recess against which the tongue abuts, and a pair of ribs for frictionally holding the tongue against the body.

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 closure includes a shell of relatively rigid plastic material having a deck and a peripheral skirt, at least one recessed shoulder in the deck adjacent to the skirt, and a plurality of angularly spaced external channels extending along the skirt from the recess. An external feature of flexible resilient second plastic material different from the first plastic material is integrally molded onto the shell within the recessed shoulder and the channels. By way of example only, the shell may be of polypropylene material and the external feature may be of thermoplastic elastomer material. Lock elements, such as openings in the deck recessed shoulder and/or pegs in the skirt channels, cooperate with the external feature molded onto the shell to retain the external feature on the shell.

Abstract: A toggle-action dispensing closure according to one embodiment of the present invention includes a base having a deck with a dispensing opening, a recess adjacent to the deck and a toggle lid pivotally carried on the deck. The lid has a first portion overlying the deck and closing the dispensing opening in a closed position of the lid, and a second portion overlying the recess in the closed position of the lid. The lid can be pivoted between its closed and an open position in which the first portion of the lid is spaced from the deck and the second portion of the lid is disposed at least in part in the recess. The lid has a first protrusion and the base has second and third protrusions that cooperate with the first protrusion on the lid to releasably hold the lid in its closed position and in its open position respectively.
