  • Patent number: 4325499
    Abstract: A continuous, extended spray pump which has two opposing and coaxial chambers. The upper chamber is fitted with an upper and middle piston urged upwardly by a spring, the lower chamber is fitted with an opposing piston urged upwardly by a spring. When the upper and middle pistons are depressed, pressure is built up and the lower piston moves downward. Discharge occurs when the lower end of the lower piston is deflected by nibs on the inside of the upper chamber.

  • Patent number: 4313568
    Abstract: A nozzle for fitment to hand actuated liquid pumps having a barrel portion with a bore therethrough for passage of a liquid is disclosed. The nozzle features an integrally formed nozzle cap which is mounted to the barrel and which encloses an integrally formed sealing structure. The sealing structure provides a peripheral seal to provide a liquid-tight seal around the barrel between the nozzle cap and the barrel. The sealing structure also provides a check valve portion which is movably positioned at the mouth of the bore. The check valve is biased to form a liquid-tight bore seal. This bore seal is overcome by liquid pressure which builds in the bore upon actuation of the pump. Also provided is a spray member which is fittable within the nozzle cap and which is in abutment with the end wall of the nozzle cap. The spray member, along with the wall of the nozzle cap which it abuts, form a path for the liquid as it is dispensed, which path will cause the liquid to break up and form a spray pattern.

  • Patent number: 4313569
    Abstract: A three-piece nozzle is disclosed, for fitment to a hand actuated liquid pump having a barrel portion with a bore therethrough for passage of liquid. The nozzle features an integrally formed nozzle cap which fits around the end portion of the barrel. Enclosed within the nozzle cap is an integrally formed nozzle seal which forms a peripheral liquid-tight seal around the barrel between the nozzle cap and the barrel. Also provided is an integrally formed check valve which is movably positioned at the mouth of the bore and which is biased towards the mouth of the bore to form a liquid-tight bore seal. The bias is overcome, to open the liquid-tight bore seal, upon actuation of the pump which provides liquid pressure in the bore to act against the check valve.

  • Patent number: 4278189
    Abstract: An accumulative pressure pump that has upper and lower pressure chambers of different diameters, each of which is provided with a piston having a connected stem. Inlet and outlet check valves are provided. The outlet valve opens on accumulation of pressure on the downward stroke of the two pistons. The lower portion of the inner sidewall of the lower chamber is provided with a rib or a recess to permit any air trapped in the two chambers to be expelled through a bottom opening that is provided in the lower chamber. The dip tube is connected directly to the second piston and has its end abutting or adjacent the bottom of the container and is reciprocal with the second piston whereby its lower end moves into the lowermost portion of the container to permit substantial removal of the entire contents of the container.

  • Patent number: 4257561
    Abstract: A child-resistant nozzle connectable to a spray dispensing device. The child-resistant nozzle assembly of the present invention includes a nozzle having a slot in the upstream end for receipt of a lug connected to the pump body. The lug may be depressed by the fingers of the user to selectively engage or disengage the slot in the nozzle. When the lug is engaged in the slot in the nozzle, no liquids can leak or be dispensed from the nozzle.

  • Patent number: 4227650
    Abstract: A fluid pump dispenser includes a nozzle structure having a flexible member which functions as an outlet check valve and O-ring seal, and which cooperates with a threaded nozzle cap to vary the discharge pattern of the dispenser responsive to twisting adjustment of the cap. Fluid is discharged through the nozzle structure by actuating a trigger to reduce the volume of a pump chamber in communication with the outlet check valve. The volume of the pump chamber may be reduced by operating a piston within the chamber or by flexing a wall of a tubular member having an open end in communication with the outlet valve.

  • Patent number: 4206851
    Abstract: A thermoplastic tamperproof closure for fitment to a container is disclosed. The container has a threaded neck and an outwardly extending flange beneath the neck threads. The closure features a top wall with an annular sidewall downwardly depending therefrom and having about its inside surface a thread for cooperation with the container thread. Attached to the sidewall by a plurality of spaced apart, non-fracturable ribs is a fracturable band which will fit in a position of intereference under the container flange. This fit is achieved by applying heat to the ribs and band, after the closure is fitted to the container, causing the band and ribs to shrink to the position of interference.

  • Patent number: 4197955
    Abstract: A tamper-proof package having a container and closure is disclosed. The container has a threaded neck and an outwardly projecting flange beneath the container threads. The cap has a top wall and a downwardly depending sidewall with the sidewall having inwardly projecting, helical threads for cooperation with the container threads. Provided as part of the cap is an annular cap flange which is disposed beneath the cap sidewall and adapted for connection to the container flange. Holding the annular cap flange to the cap body is achieved by the utilization of a plurality of elongated connecting ribs. These connecting ribs extend downward from the cap sidewall to the cap flange and have a direction of slope opposite the direction of the helix angle of the cap helical thread.

  • Patent number: 4133449
    Abstract: An integrally formed, one-piece, generally rectangular, plastic container particularly adapted for holding medicines is disclosed. The container includes a generally rectangular bottom section which is connected to a rectangular top section by means of an integrally formed, flexible, plastic hinge at the rear of the two sections. In the closed position, the top section overlies the bottom section and latch means lock the two sections together. The bottom section has a planar bottom wall, two opposed, upturned sidewalls, an upturned front wall, and an upturned back wall, all of which are integrally formed and connected to each other. The top section has a planar top wall, two downturned sidewalls and a downturned front wall, all of which are integrally formed and connected to each other, and a downturned back wall integrally formed and connected to the top wall. The thickness of the container at the connection of the downturned back wall and the top wall is reduced.
