摘要： A dispenser for use with a liquid product including beads which are rupturable to release additives when rubbed between the hands of a user. The dispenser includes a discharge head reciprocable between pressure and return strokes, and a valve assembly for respectively allowing and preventing liquid product from being discharged during the pressure and return strokes. The valve assembly includes ribs for guiding movement of a check valve disposable in respective valve open and closed positions in which the check valve is disposed out of and in contact with a valve seat. The valve assembly includes primary fluid passages for permitting passage of the liquid and beads into a pump cylinder, and secondary fluid passages for permitting displacement of the beads during translation of the check valve between the valve open to the valve closed positions for thereby preventing accumulation of beads between the check valve and its valve seat.

摘要： An applicator is adapted to be mounted on a hollow piston stem of a manually reciprocable pump dispenser for applying a cleaning liquid to a fibrous article such as fabric, rug or carpet or the like from a container of liquid to which the dispenser is mounted. The applicator has a domed outer convex rigid wall with at least one discharge port in communication with the discharge passage of the piston stem, and an outer surface of the domed wall is textured for rubbing the cleaning liquid into the fibers article during a cleaning operation. An overcap is connected to a side wall of the applicator by a hinge permitting the overcap to cover the outer surface of the domed wall when not in use. And, a container closure may be provided in telescoping relationship to the applicator which is rotatable about its central axis between lock and unlock positions.

摘要： A manually actuated pump dispenser assembly has a positioning leg on an eccentric flange thereof to facilitate the offset mounting of the assembly to an offset opening in the neck of a container of liquid to which the pump assembly is to be mounted. And, an arcuate skirt associated with the leg positively interferes with an improper mounting of the pump assembly in place.

摘要： A precompression pump sprayer has a variable volume suck-back chamber in communication with the discharge orifice for inwardly suctioning any residual liquid away from the orifice and the spin mechanics to avoid clogging as a result of dried accumulated product. In one embodiment a cover on the plunger head is spring loaded and therewith defines the suck-back chamber. In another embodiment the plunger head is spring loaded on the piston stem, such that in both embodiments a top end wall of the suck-back chamber is shiftable relative to the piston stem independently of piston reciprocation. The biasing spring has a spring force permitting a shifting of the end wall to reduce the volume of the suck-back chamber at a peak pressure reached in the pump chamber beyond the threshold pressure required to open the discharge valve, at which time the spring is compressed. The restoring force of the spring causes the top end wall to shift to expand the volume of the suck-back chamber.
摘要翻译：预压泵喷雾器具有与排放孔连通的可变容积的吸回腔，用于向内吸引离开孔和旋转机构的任何残余液体，以避免由于干燥的积聚产物而导致的堵塞。在一个实施例中，柱塞头上的盖子是弹簧加载的，并且由此限定了回吸室。在另一个实施例中，柱塞头弹簧加载在活塞杆上，使得在两个实施例中，独立于活塞往复运动，吸回腔的顶端壁可相对于活塞杆移动。偏置弹簧具有允许端壁移动的弹簧力，以在泵室内达到的峰值压力下减小吸回腔的体积，超过打开排出阀所需的阈值压力，此时弹簧为压缩弹簧的恢复力使顶端壁移动以扩大吸回腔的体积。

摘要： A trigger actuated pump dispenser includes a housing mounted on a container of gas/vapor producing liquid product capable of generating a superatmospheric pressure in the container, the housing including a piston/cylinder unit and a container air vent which includes a vent chamber and a vent port establishing communication between the vent chamber and the interior of the container. The air vent has a pressure vent outboard of the vent seal connected to the piston for releasing pressure from the container via the vent port and the vent chamber upon outboard movement of the piston to such outboard location in response to the superatmospheric pressure in the container.

摘要： 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.

摘要： An anti-backoff, removable closure for connecting a manually actuated liquid dispenser to a container includes a closure cap having internal threads for mating engagement with similar threads on the outside of the container neck finish, both the cap and the neck finish having mutually engageable ratchet teeth mechanically retaining the closure to the container. The teeth inside the cap each have a trailing face lying in a plane sloping in a loosening direction of the cap relative to the central axis of the cap for producing a camming action between the cap teeth and the neck finish teeth, tending to cam the cap off the container in response to closure unthreading rotation.
