Spigot and collar assembly

Container

The invention is a trigger sprayer comprising a tubular nozzle bushing and a nozzle cap rotatable on the bushing. The nozzle cap has an end wall with a first swirl chamber formed on the rear face thereof offset from the axis. Passages to a second chamber are diametrically opposite the first chamber. Both chambers have orifices directed out the front of the cap. The first orifices is surrounded by a foaming sleeve. The second orifice is positioned forward of the first orifice so that the spray cone emanating from the second orifice does not hit the foaming sleeve. The cap can be rotated to connect liquid from the delivery tube to the swirl chamber for one or the other orifices.

Trigger sprayer having sprayer/foamer selector nozzle cap

A valve assembly and an ergonomic, convenient to use container for liquids such as heavy duty detergents, fabric softeners and the like, which includes the valve assembly. The valve assembly preferably includes at least two separate pieces, (i) a valve, and (ii) a collar for securing the valve to the container.

Spigot assembly for container

This articulated trigger/cover unit for a pump dispenser is formed with retainers on proximate relatively moveable walls to hold parts in stable configuration for handling by automatic assembly equipment.

Vent closure

Finish has bayonet provisions, each including axial catch portions, stop, rib and detent ridge downward from the distal end of the catch portion. Finish also has ramp provisions, each including axial stop and sloping wedge portion extending down from top of axial stop and sloping at 40&deg; from an imaginary circumferential line at the base of the wedge portion. The stops, detent ridges and wedges all provide tactile notification to user as to where lugs on a cooperant cap are vis-a-vis catch portion and top of finish.

Bayonet-type finish for a container

Pump dispenser trigger

A retainer for holding a pump body onto a container is formed with an annular trough having a passage offset from the axis of the retainer and permitting escape of build-up pressure in the container to the outside. The trough has a radial surface in which the passage terminates. An annular laminate layer of gas-permeable/liquid impermeable material is secured to the radial surface covering the passage.

Trigger pump dispenser shroud

A closure for a container-and-closure sealing system embodied in a container and closure package, and method of making the same. The container has an open mouth surrounded by a cylindrical neck wall having internal threads and an open upper edge. The closure is a cap/dispensing cup type and has a skirt with external threads adapted for threaded receipt within the container neck wall. A circumferentially continuous flange projects outwardly from the skirt and has a conical portion adapted for cam engaging, trapping and sealing with the open upper edge of the neck wall as the closure is threaded into this wall. The closure skirt also has a circumferentially continuous plug-type sealing surface that extends radially outwardly from the skirt between the trapping flange and closure external threads adapted for interference sealing engagement with the neck wall as the closure is threaded thereinto. The materials of the closure and container may differ in hardness relative to another so that either the plug seal rib of the juxtaposed neck wall surface deforms under closure/container engaging forces to thereby enhance the sealing capability and life. The flange has a conical skirt wall portion integrally dependent from a flange radial wall portion that is adapted to sealing cam wedge embrace the neck open upper edge and creates increasing squeeze force as the closure is threaded into the neck wall. A concentrically intermediate annular seal is also provided in the form of V-rib or liner material interposed in assembly between the container upper edge and the flange radial wall portion. The container neck wall may have a circumferentially continuous internal groove disposed between the neck internal threads and open upper edge for receiving the closure plug seal rub by interference snap fit when the closure is threaded into the wall and reaches closed position thereon to thereby enhance removal torque capability.

Spray pump transition collar

Shroud for pump dispenser

This finish has bayonet provisions, each including circumferential catch portions, a first stop rib and a detent ridge downward from the distal end of the catch portion. This finish also has ramp provisions, each including a second stop rib and a sloping wedge portion extending down from top of the stop rib and having a surface sloping at 40.degree. from an imaginary circumferential line at the wedge portion. The stops, detent ridges and wedge surfaces all provide tactile notification to user as to the location of lugs on a cooperant cap on the finish.
