Abstract: A carrier tray for deformable beverage containers prevents doming of the underside of beverage cans and abrasion of adjacent cans during transport. The base of the carrier includes upwardly projecting members (62, 63) which are taped to conform to the shape of the underside of the containers. An additional feature of the upwardly projecting members is the retention of the cans in a vertical position.

Abstract: A syringe in which a piston is releasably latched to a plunger for reciprocation in a cylindrical barrel, wherby the piston will become disengaged from the plunger upon one cycle of rearward and then forward movement of the plunger and piston in the barrel, followed by subsequent rearward movement of the plunger in the barrel, thus rendering the syringe incapable of reuse. The piston is held to the plunger by latching arms which move to an over-center position between their latched and unlatched positions.

Abstract: A universal case capable of transporting PET bottles of a base-cup type and a petaloid type includes an outer shell 4, 6 and a plurality of support ribs 32, 34, 36, 38 which are shaped to define a plurality of bottle pockets 25 for receiving the bases of PET bottles. A bottle seating structure 40 associated with each bottle pocket 25 includes a base-cup-bottle alignment structure 42, 44, 48 and a petaloid-bottle alignment structure 54, 56. The two alignment structures 42, 44, 48, 54, 56 are adapted to orient PET bottles respectively of the base cup type and the petaloid type seated in the bottle pocket 25 so that the longitudinal symmetry axis of the bottles extend generally parallel to the pocket centerline. The case also includes a case rest 60 associated with each bottle pocket 25. The case rest 60 has a central-base-surface bottle-to-case load-transmission surface 61 facing the bottle pocket 25 and a case-to-closure load-transmission surface 63 facing outward from the bottom of the case.

Abstract: An universal case is adapted to transport PET bottles of both a base-cup type and a petaloid type. The case 2 includes an outer shell 4,6 and a plurality of support ribs 30, 32, 34, 36, 80 for reinforcing the shell. The outer shell and the support ribs are shaped to define a plurality of bottle pockets 25 for receiving the bases of PET bottles. A bottle seating structure 40 is associated with each bottle pocket 25 and includes a plurality of dual-base-engagement projections 52, a base-cup-bottle alignment structure 42 and a petaloid-bottle alignment structure 48, 50. The dual-base-engagement projections associated with a bottle pocket 25 extend generally parallel to a centerline of the pocket and project into the pocket. The number of dual-base-engagement projections equals the number of petaloid lobes 124 formed in the base of a PET bottle of the petaloid type.

Abstract: A one-piece dispensing closure has a laterally oriented dispensing opening therein, communicating with a longitudinal bore. A cap is integrally joined to the closure by a "living" hinge at one side of the cap and closure, and a male plug depends from the underside of the cap in a position to close the longitudinal bore and dispensing opening. The plug has spaced sealing areas thereon which cooperate with spaced sealing areas in the bore, and the cap has a detent on a marginal portion opposite the hinge to retain the cap in a closed position and to also retain the cap in an open position. The detent also effects a seal in the dispensing opening when the cap is in a closed position. Further detents on the cap and closure cooperate to limit opening movement of the cap relative to the closure. Thus, when the cap is closed, primary and secondary seals are provided in both the bore and dispensing opening, and when the cap is open, a seal is maintained in the bore.

Abstract: A multi-function dispenser may be adjusted to obtain a spray or stream of the material dispensed, either as a long duration discharge of the material or as intermittent discharges corresponding to actuation of a trigger actuator, or as a continuous discharge during actuations of the trigger, depending upon functional design variables. Structure is provided for storing an accumulated amount of material upon repeated operations of the trigger, for subsequent prolonged discharge of the material, or the accumulating structure may be bypassed for intermittent discharges of the material as the trigger is operated, or the accumulating structure may function as a holding chamber whereby a continuous discharge of the material may be obtained while the trigger is being operated.

Abstract: A non-propellant operated, duration spray dispenser includes structure for mechanically pressurizing the material to be dispensed by pumping it into an expansible bulb for storage under pressure for subsequent dispensing of the material, and a snap-acting positive shut off valve is provided to terminate discharge of the material when pressure falls below a predetermined minimum.

Abstract: A trigger operated dispenser includes a plurality of expansible chambers, with one of the chambers comprising a pumping chamber connected to be operated by the trigger, and another chamber connected to receive product from the pumping chamber and operative to expand and accumulate an amount of product for continuous discharge of the product through the nozzle, whereby continuous discharge of the product is obtained during both pressurization and intake modes of operation of the trigger operated pumping chamber.

Abstract: A trigger operated dispenser includes a plurality of chambers with movable members therein, and operable to draw material from a container, pressurize it, accumulate a quantity of material under pressure, and discharge the material to a point of use. An adjustable member communicates with the chambers for selectively obtaining either continuous or intermittent discharge of the material.

Abstract: An economical and easy to operate mechanically operated dispensing device has a rotatable actuator connected with at least one expansible chamber to effect operation of the expansible chamber to draw material to be dispensed from a container into the expansible chamber and to then pressurize the material. An expansible bulb is connected with the expansible chamber and with a dispensing nozzle, and has a volumetric capacity several times as great as the expansible chamber. Valves are associated with the bulb to control flow into and out of the bulb, whereby the rotatable actuator and expansible chamber are operative to repeatedly draw material from the container, pressurize it and transfer it under pressure into the bulb, the bulb expanding as material is added thereto, and the elasticity of the bulb being such as to exert a substantial pressure on the material in the bulb.

Abstract: A child-resistant closure for a container having a screw threaded neck, includes a cap having an end wall and a depending, cylindrical skirt with screw threads therein for mating cooperation with the screw threads on the container to releasably secure the cap to the container. Interengaging, selectively releasable detent members are formed on the cap and container for resisting removal of the cap by a child, but enabling an adult to remove the cap. The detent members include a plurality of detents on the cap and a cooperating detent on the container, wherein the detents have first cooperating, interengagable surfaces to enable the detents to move past one another in a cap tightning direction, and second cooperating, interengagable surfaces to prevent movement of the detents past one another in a cap loosening direction.
