摘要:
A manually actuated dispenser having a flexible weighted dip tube is mounted to a container of liquid to be dispensed without entanglement by the dip tube by the provision of a tubular extension on the tube retainer which surrounds the tube and has a releasable holder for maintaining the tube in a collapsed condition during installation within the container, the retainer being dislodged or being soluble in the liquid in the container for releasing the stored dip tube permitting the ballast weight at its end to extend the tube toward the container bottom wall assuring a wetted condition of the inlet end of the tube during all attitudes of liquid dispensing.
摘要:
A nozzle cap of a trigger actuated pump sprayer is produced of two different materials using a bi-injection molding process for delimiting the markings on the outer faces of four walls of the cap serving as indicia relating to specific rotative positions of the cap.
摘要:
A sprayer includes a discharge valve assembly and includes an integrated poppet valve, spring and volume reducer. The spring includes more than omega-shaped form, each with relatively flat sides. The spring can have sides with portions sufficiently wide to substantially extend across the valve chamber to provide stability to the spring and prevent buckling. The flat sided omega-form construct is relatively easy to manufacture via molding and the ends of such construction provide suitable locations for integrated molding with the valve and the volume reducer.

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.
摘要:
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.
