A battery-operated dispenser includes a shell with a moveable slider for extending a barrel of the dispenser to allow targeted application of a fluid or product from a container to which the dispenser is attached.

Battery operated dispenser

A dispensing system includes a liquid dispensing tap and an associated or integrated measuring cap/cup. The dispensing tap and cap/cup are configured such that the cap/cup is assembled with the tap prior to installation onto a container, and stays assembled with the tap during installation onto the container at the filling line, and which can later be removed for use and then reattached to the tap or container after use by the consumer.

An actuator with an anti-drool valve is provided for attaching to or mounting on an aerosol container. Aerosol actuators, and more recently trigger actuated aerosol actuators, may include a manifold which fits to or communicates with a valve on an aerosol container or can. Aerosol containers or cans typically contain a propellant such as a compressed gas or a volatile hydrocarbon. The contents of the container, along with the propellant, are held in the container by a container valve.

Snap fitment systems () and valve systems () for holding valves, pumps, sprayers, or other devices to a container () may include plastic components which snap to a container allowing the valve system to be used to evacuate product in the container or allowing the valve system to be used to fill and evacuate product in the container.

Plastic valves and methods of using the same

A snap fitment system for attaching a closure such as a valve body to a container may include one or more fingers attached to the valve body and held in a securing position about the container by a retaining ring.

A manually operated sprayer for a container of liquid to be sprayed includes variable volume pump means having liquid inlet and outlet means for discharging the contents of the container. The sprayer further includes a control module having product and vent valves reciprocably disposed therein, the product and vent valves being simultaneously reciprocable by means of the manual actuator between valve open and valve closed positions. In the valve open position, the product and vent valves respectively prevent flow of product and air respectively into the liquid inlet means and into a vent passage in communication between atmosphere and an interior of the container, and in the vent closed position, the product and vent valves respectively enable flow of product and air respectively into the liquid inlet means and into the vent passage.

Discharge/vent module for power sprayer

In one embodiment of a dispensing system for connecting a remote power sprayer to a container of liquid, a flexible delivery tube includes one end non-removably connected to a remote retainer and the other end non-removably connected to a connector hose. The remote retainer and connector hose each include strain relief elements which respectively include a retainer adaptor and a connector adaptor for relieving the connection strain between the tube, the remote retainer and connector hose, as the power sprayer is being pulled and maneuvered during use. In a second embodiment, the flexible delivery tube includes one end non-removably connected to a remote retainer and the other end disposed freely in a container, but plugged onto a connector hose and including a spring weight slidably disposed thereon.

Trigger sprayer having secure delivery tube connection

A three part housing for a battery powered spray head includes a left half shell, a right half shell and a hinged top. The batteries are located in the upper portion of the housing below the hinged top (battery cover). The inner front of the top is provided with a downward depending latch member and a spring biased latch member is provided inside the housing. The spring biased latch member is actuated by inserting a pin (or stylus) through a hole in one of the half shells. This prevents accidental opening of the battery cover.

A flexible dip tube for a hand held sprayer has a filter element with a projection extending into the distal end of the dib tube for frictionally mounting the filter element thereto, the other end of the filter element extending beyond the distal end and containing filter material in communication with the interior of the tube, and a weight surrounding both the distal end and the projection of the filter element or weighting down the distal end during use.

Flexible dip tube filter with weight

A trigger actuated pump sprayer has a reduced number of parts to render it low cost without compromising any pump function. A combined inlet/discharge valve unit is located in a liquid passageway leading from the inlet end of the pump body. The unit has a pair of axially spaced apart frusto-conical valve skirts diverging outwardly from the common stem on which the valve skirts are provided. The valve skirts straddle a pump chamber port, and the unit may be mounted in place by a dip tube retainer or the retainer may be eliminated with the unit coupled to the pump body itself, fixed in the passageway directly by the dip tube, or made integral with the unit. The trigger actuator has an integral piston return spring, the actuator being fixed to the pump body, and the trigger lever of the actuator being coupled to the pump piston.

Trigger acutated pump sprayer

A trigger actuated sprayer for dispensing disparate liquids separately stored in separate liquid compartments includes a pair of axially aligned, interconnected pistons of relatively larger and smaller diameter reciprocable in unison within relatively larger and smaller diameter cylinders for therewith defining larger and smaller variable volume pump chambers, the smaller diameter piston valving one fluid from its chamber to be combined with the other of the fluids in the other chamber during each compression stroke of the pistons. The combined liquids are dispensed from the chamber upon trigger actuation during each compression stroke.

Trigger sprayer for dispensing liquids combined from separate

A foamer nozzle assembly has a foaming barrel defining a turbulence chamber for creating foam upon actuation of the trigger of a trigger sprayer as the conical spray impacts against the smooth inner surface of the barrel as so to emerge as loosely compacted, large foam bubbles having a relatively wide foam spread. A foaming grid in the form of an offset rectangular mesh screen is mounted on a hinged panel for movement between operative and inoperative positions. In the former the grid lies coaxial with the discharge orifice and provides a supplemental foam generator for breaking up the foam bubbles into finer and more concentrated foam having a relatively smaller foam spread. The grid comprises first and second sets of ribs lying in first and second parallel planes, the ribs of the first set being contiguous to the ribs of the second set, and the ribs being mutually spaced apart to define uniformly sized openings therebetween. The ribs of both sets have flat surfaces facing upstream and lie perpendicular to the central axis of the barrel.
