A foam dispenser has a foam-generating pump (1) mounted on a container (100) to hold liquid. The pump (1) has a liquid intake conduit with a ball valve (27) and an air intake conduit (45) provided partly by a jacket component (4) fitting around the pump body (2) with clearance. The pump has structure defining a mixing zone (50) for mixing air and liquid, a foam chamber (28) for holding foam received from the mixing zone, and a discharge conduit leading from, the foam chamber to a discharge outlet (36). The mixed air and liquid pass through a permeable foam, regulator mesh (54), One or more air inlets (47) lead into the mixing zone (50) from the air intake conduit (45). A liquid inlet in the form of a restricted jet orifice (89) leads into the mixing zone (50) from the liquid intake conduit, upstream of the inlet ball valve (27). A regulator mesh (53) is also provided between the liquid inlet and mixing zone.

Provided is a trigger-type liquid dispenser (1) including an operating lever (6) held swingably by a main body portion (3) in which a pump is disposed and including a spring member (7) that imparts restoring force to the operating lever (6). The trigger-type liquid dispenser (1) is configured to draw, pressurize, and force-feed a content liquid contained in a container (C) to dispense the content liquid through a nozzle (5), by actuating the pump in response to the operating lever (6) being pulled repeatedly. The spring member (7) is held swingably with respect to the main body portion (3), and, in response to the operating lever (6) being pulled, the spring member (7) undergoes elastic deformation and swings with respect to the main body portion (3).

A pump for connecting the inside and the outside of a product vessel for pharmaceutical use including an upstream end for passing a product intended for extending into the vessel and for being in fluid communication with the vessel and, downstream from the upstream end, a check valve switching between configurations for sealing and passing a product. The upstream end is extended upstream by a member forming a passage of a product in a labyrinth, referred to as labyrinth-forming member.

The present disclosure relates to a spraying apparatus for spraying a liquid onto a surface. The spraying apparatus includes a tank configured to store a liquid, a neck extending from the tank and defining an opening, a pump assembly including a collar removably attached to the neck, a pump configured to draw the liquid from the tank when actuated, and a housing defining a cavity therethrough to provide a carrying handle. A wand, separate from the tank, includes a body and a nozzle assembly, having a hub rotatably attached to the body and a plurality of nozzles circumferentially arranged around the hub and extending radially outwardly therefrom. An elongate hose, having a first end and a second end, interconnects the tank and the wand by attaching to the pump assembly of the tank at the first end and the body of the wand at the second end.

A manual pump (P) having a pump body (B) defining a slide cylinder (F) for a piston (K) secured to an actuator rod (S); a pump chamber (C) and an outlet valve (V) arranged between the pump chamber (C) and a dispenser orifice (O) so as to dispense the fluid from the pump chamber (C). The pump includes an inlet valve (2, 12) arranged between the pump chamber (C) and an inlet (I) of the pump (P) to take the fluid into the pump chamber (C) from the reservoir (R), the inlet valve having a movable member (2) that selectively bears against a valve seat (12), a return passage (23) enabling a fraction of the fluid that is put under pressure in the pump chamber (C) to escape therefrom without passing via the outlet valve (V). The return passage (23) creates a lack of sealing at the inlet valve.

A trigger-type liquid sprayer including: a sprayer main body; and a nozzle member. The sprayer main body includes: a vertical supply cylindrical part; a trigger mechanism; a reservoir cylinder; and a reservoir plunger. The trigger mechanism includes: a main cylinder; a main piston; and a biasing member.

A system for dispensing a personal care fluid, such as a hand soap or the like. The system includes a dispenser and a refill cartridge. The dispenser includes a dispenser body having a refill cavity and a dispenser lid configured to be coupled to the dispenser body. There may be a pump sub-system mounted to the dispenser lid, or alternatively the personal care fluid may be dispensed by squeezing the dispenser and refill cartridge. The refill cartridge is configured for slidable insertion into and removal from the refill cavity of the dispenser body. The personal care fluid system is designed so that a user can readily and easily change out/replace the refill cartridge for use with a common dispenser, dispenser lid, and pump sub-system.

Fluid product device having a dispenser joined to a reservoir containing fluid product, the dispenser having a pump body containing a dosing chamber, and a dispensing head with a dispensing aperture, a plunger secured to the dispensing head to slide in the dosing chamber between rest and actuation positions. The dosing chamber has at least two openings, a first opening for filling the dosing chamber and a second opening connecting the dosing chamber to the dispensing aperture. The first opening is made in a cylindrical portion of the pump body in which said plunger slides during actuation, the first opening connecting the dosing chamber to the reservoir when the plunger is in the rest position and isolating the dosing chamber from the reservoir when the plunger moves out of its rest position. The dosing chamber is filled through the first opening when the dispenser is joined to the reservoir.

A spray bottle assembly includes a bottle having a neck, and a spray head assembly having a base cap configured to removably attach to the neck. The base cap has a feature that rotationally locks the base cap relative to the neck to constrain the spray head assembly in a predetermined plane. A multi-label system for a spray bottle includes: at least one strip, the strip including connected labels with differing information printed on each side, each label including a ring for positioning on a neck of the spray bottle. A pumping mechanism for a spray bottle includes: a unibody plunger having a sleeve section that variably inverts and overlaps an end thereof thus defining an internal volume that varies with the disposition of the sleeve section relative to the end. A pivoting head section that allows servicing of functional seal components.
