Abstract: 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.

Abstract: A trigger sprayer has a shroud at least a portion of which is configured to communicate information about the liquid in the bottle to which the sprayer is attached. The shroud is provided with a shape and/or texture, preferably in conjunction with a color, which suggests a quality of the liquid such as its intended use, the identity of its manufacturer, its scent, etc.

Abstract: A sustained duration non-aerosol mechanical sprayer includes a spray head which is screwed onto the top of a bottle. The spray head includes a spring biased piston in a cylinder, a lever which is coupled to the piston via a flexible cable. A thumb support is provided to facilitate movement of the lever. A load bearing surface is provided to absorb force exerted by moving the lever. Anti-rotation structure is provided to locate the spray head relative to the bottle. A window in the spray head allows the contents of the cylinder to be viewed. According to some embodiments, the nozzle is located at one end of the spray head and the end of the accumulator to which the inlet and outlet are connected is located at an opposite end of the spray head.

Abstract: A battery operated spray pump includes a piston pump wherein the axis of the pump is arranged at an angle relative to the axis of the spray discharge and the fluid inlet. In addition the batteries lie substantially on top of the pump rather than behind it. This allows the spray head to assume an overall size which is almost completely within the foot print of the bottle to which it is attached and also provides the spay head with better balance.

Abstract: A battery powered solenoid actuated liquid tap dispenser has a solenoid coil, an armature extending through the coil, a valve seal coupled to the armature, a spout engaged by the valve seal, an electrical actuation button adjacent to the spout, and a manual actuation button atop the armature. The electrical actuation button is arranged to be engaged by the lip of a cup placed under the spout and cause the armature to move in the coil thereby moving the valve seal away from the spout. Alternatively, the armature may be moved by the manual actuation button.

Abstract: 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 upper edges of the half shells are provided with flanges which are received inside the cover when the cover is closed. The left and right half shells are also provided with a gutter-like structure adjacent to the battery cover which extend across the sides and down the back of the housing.

Abstract: 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.

Abstract: An assembly for effecting a quick connect of a flexible fluid delivery tube to a rigid dip tube for a liquid sprayer is provided. The assembly is mounted to a container of chemical liquid to be sprayed by a closure cap having a depending annular wall defining a cavity into which an adaptor for the delivery tube extends and is snap fitted in place by the provision of a retention feature coacting between a nipple of the adaptor and the annular wall. A vent port located in the annular wall in the vicinity of the coacting retention feature with an air gap provided between the vent port and the upper surface of the closure end wall. Alternatively, the vent port is located in the end wall of the closure. A cover is provided for sealing closed both the inlet opening from the container and the vent port in a condition of non-use.

Abstract: A trigger actuated fluid dispenser for simultaneously dispensing disparate fluids, separately stored in separate fluid compartments of a container includes a mixing manifold for intimately mixing the fluids together and the nozzle assembly in which the mixture is channeled into a pair of spray nozzles through which the mixture of fluids issue as it sprays, upon simultaneous pumping of the disparate fluids by a single trigger actuator directing the disparate fluids along separate discharge paths to the mixing manifold.
