摘要： A fluid pump dispenser includes a spring biased pump piston having a generally hollow stem and reciprocable between pressure and return strokes within a pump cylinder therewith defining a variable volume pump chamber for dispensing fluid through a discharge opening at an outer end of the stem. The stem defines a valve controlled discharge passage leading from the pump chamber to the discharge opening. A driver nut may be mounted adjacent the pump piston and include at least one flange engaged with at least one respective spiral turn on a spindle disposed within the pump chamber to thereby rotate the spindle during reciprocation of the pump piston. A dip tube may be disposable within a container and affixed to the spindle for rotation with the spindle. A figurine may be mounted onto the dip tube for complementary rotation with the dip tube and the spindle.

摘要： A trigger actuated pump sprayer has a nozzle cover for sealing the discharge orifice closed against leakage by the provision of a cup-shaped element on the cover which telescopes about a nosepiece in which the orifice is formed and fluid tightly engages a seal ring extending laterally outwardly of the nosepiece in the closed position of the cover. The cover is locked in its closed position and is rendered child-resistant by the provision of at least one resilient lock pin extending through an opening in the sprayer housing requiring an inward depression of the lock pin with one hand and a flipping open of the cover with the other hand.

摘要： A trigger pump sprayer has an external cover plate mounted on and parallel to an end wall of the pump body containing the discharge orifice for transverse sliding movement between an orifice covered position at which a first portion of the cover plate overlies the orifice and an orifice uncovered position at which a second portion of the cover having a through opening lies coaxial with the orifice. Guide tracks on said end wall supporting said plate for sliding movement are sloped toward the end wall for camming an inner surface of the first portion of the plate toward the confronting outer surface of the end wall for fluid tightly sealing the orifice closed against leakage in the covered position.

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.
