A method of filling a fluid dispenser is provided and a method for operating power driven pump in a dispenser is provided.

Fluid product dispenser (D) having a reservoir (R) defining a bottom (R1) and an opening (R2), and a dispensing head (T) integrating a dispensing member (P) defining a vent path through which outside air can penetrate into the reservoir (R). The dispensing member (P) has a dip tube (TP) that extends into the reservoir (R), the dip tube (TP) having an inlet (Ti) close to the bottom (R1) of the reservoir (R). The inlet (Ti) of the dip tube (TP) is provided with a shut-off valve (V) having a movable member (V6) and a seat (V5), the movable member (V6) is urged into sealed contact with the seat (V5) by the fluid product when the dispenser (D) is upside down, while the movable member (V6) is urged away from the seat (V5) by the fluid product when the dispenser (D) is upright.

Described is a dispenser for dispensing a fluid, made of plastic material, including: —a ring nut having an inner cylindrical wall equipped with partial grooves; —a concertina-like deformable element, defining a return spring of the dispenser and including a cylindrical lower projection equipped with relative partial grooves; —a ring designed to define with the ring nut a locking system designed to define an operating configuration and a non-operating configuration of the dispenser in such a way as to pull the concertina-like deformable element in such a way as to align the partial grooves of the cylindrical wall of the ring nut and the partial grooves of the concertina-like deformable element.

A foam discharge container is a foam discharge container for discharging foam in response to a pushing operation, and includes a discharge port which is opened in a direction opposite to a pushing direction of the pushing operation and discharges foam, and a pushing portion that keeps the distance between a discharge target body receiving foam and the discharge port constant.

A fluid dispenser including a body, a chamber coupled to or formed as part of the body and configured to contain a quantity of fluid, and a piston coupled to the body and rotatable within the chamber to different position. The piston is movable relative to the chamber in a first direction along an axis to draw fluid into the chamber, and the piston is movable relative to the chamber in a second direction opposite the first direction to discharge fluid from the chamber. The piston has stroke lengths that are selectable via the different rotational positions of the piston and that are associated with metered quantities of fluid to be drawn into the chamber. An anti-reversal feature is disposed between the piston and the body. The anti-reversal feature inhibits reversal of the piston during movement of the piston in the first direction or the second direction.

Various implementations of the invention are directed toward a sanitizing door handle and/or components of such sanitizing door handle. Some implementations of the invention are directed toward a manual sanitizing door handle while some implementations of the invention are directed toward an auto-sanitizing door handle. According to some implementations of the invention, a sanitizing fluid is dispensed directly onto an exterior surface of the sanitizing door handle in connection with an operation of the door handle to sanitize the door handle. According to some implementations of the invention, a sanitizing fluid is dispensed directly onto a user's hand(s) in connection with an operation of the door handle to sanitize the user's hand(s).

Aspects of the disclosure are directed to a spray gun apparatus having a casing with a nozzle. A rod extends within the casing and has an end portion with openings therein, for dispensing material. The rod operates with the casing to move relative to one another, for selectively dispensing the material. When the nozzle is positioned such that it is offset from the end portion of the rod, fluid material is allowed to flow out of the rod and is dispensed through the nozzle. When the end portion of the rod is positioned to seal the nozzle opening (e.g., via relative movement of the casing and rod), the fluid material is prevented from being dispensed through the nozzle. In certain implementations, an adapter interface is operable for coupling to an aerosol container having the material to be dispensed, and includes a conduit coupled to the rod for supplying the material.

An applicator for a syringe is provided that includes a hub configured to be disposed at least partially within a nozzle of the syringe and defining a fluid passage therethrough, with one or barbs on the hub that frictionally and sealingly engage an interior of the nozzle in a manner minimizing void space associated with waste of deliverable material, and an applicator tip extending distally from the hub. The barb(s) may have varying diameters in order to enable the applicator to be engaged and utilized with syringes having different diameter nozzles. Further the fluid passage through the hub and applicator tip is dimensioned to minimize the volume of material that is retained within the applicator after use, thereby increasing the volume of material that can dispensed from the syringe for use in a procedure or procedures and minimize waste.

A method of filling a fluid dispenser is provided and a method for operating power driven pump in a dispenser is provided.

A dispensing pump mechanism is provided. The pump comprises integrally molded temper-evidence part between a container collar and a spout; said collar has multiple off-centre outlet channel for dispensing one or more products from the container; said collar also comprises an integrated air vent to be blocked and opened by the rotation of the spout. The whole pump can be over-molded one-piece structure with elastic parts as being actuating parts. The pump improves the functions of the pump, such as lower restitution rate, less structural parts, lower cost, water/dust proof, lightweight, easy assembly.
