The present invention relates to a dispenser for dispensing a liquid, comprising: a reservoir for storing a liquid to be dispensed; a manually operative pump arrangement disposed at a first end region of the reservoir; a conduit extending from the pump arrangement to a second end region of the reservoir distal the first end region, the conduit configured for communicating reservoir contents from the second end region to the pump arrangement; a dispense conduit extending from the pump arrangement and comprising a dispense aperture at an end region thereof, the dispense aperture in liquid communication with the pump arrangement; and an open ended tube extending in a direction away from the pump arrangement and configured to surround the dispense conduit, wherein the open ended tube extends to a position such that the open end thereof is at least coterminous with an dispense aperture end of the dispense conduit and actuation of the pump arrangement causes transfer of reservoir contents from the reservoir to the dispense aperture end of the dispense conduit.

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.

Infectious diseases may be acquired in public areas such as transportation terminals, shopping centers, schools, hospitals, restaurants and hotels. Large surface areas may be disinfected using a spray system to distribute a suitable fluid such as a disinfectant. Many existing spray systems are large and unwieldy causing operator fatigue. Some spray systems have large, heavy external tanks that provide fluid to the spray system using an external fluid hose. Disclosed is an improved portable spraying system that may be carried by a system operator. The improved system has a tank, a pump, a valve, a nozzle, and a fan all powered by a battery. The tank, the pump, and the battery are arranged to minimize operator fatigue. With the valve set to the priming position, fluid recirculates to prime the pump. Once the pump is primed, the valve is turned to the spray position to begin spraying.

Disclosed is a storage container, in which a valve coupled to an opening portion of a tube is not cut in advance, but the valve is cut when a liquid injection nozzle is inserted into the tube, such that a gap between the liquid injection nozzle and the valve may be perfectly blocked, thereby preventing a leak of a liquid. A storage container according to an embodiment of the present invention includes a tube made of an expandable or contractible elastic material, and a valve configured to be coupled to an upper end of the tube before a liquid is injected into the tube, in which the valve includes a ring-shaped support portion configured to be seated and supported at the upper end of the tube, and an elastic membrane extending from an end of the support portion and configured to close an opening portion of the tube.

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.

The mechanism comprises: a syringe comprising a syringe body, a piston comprising a piston head sealingly closing the syringe barrel, a rod and a gripping member carried by the rod; a movement actuator for moving the plunger in two opposing directions along the axis of movement of the piston in the syringe body, the movement actuator comprising a movement member and a locking device for locking the gripping member, capable of switching from an open configuration for receiving the gripping member to a closed configuration for immobilizing the gripping element in which the gripping member is secured in translation with the movement member in the two opposing movement directions.

Disclosed is a refillable fluid product dispenser comprising: a fluid product reservoir (R) defining a neck (R2); a dispensing member (P) that is mounted on the neck (R2) and comprising an inlet (P2); and a fastening member (2, 2) for fastening the dispensing member (P) onto the neck (R2); a dip tube (D) that is connected to the inlet (P2) of the dispensing member (P) and extends into the reservoir (R); the dispenser being characterised in that the dip tube (D) is secured to the fluid product reservoir (R) by means of a support (1) that forms at least one filling window (15) communicating directly with the inside of the fluid product reservoir (R), the fastening member (2, 3) enabling withdrawal of the dispensing member (P), thus providing access to the support (1) in order to fill the fluid product reservoir (R) through said at least one filling window (15).

A dispenser for substances includes an outer shell with a deformable outer wall which encloses the deformable container arrangement and at least one balancing valve for balancing air, wherein an air filled intermediary gap is located between the outer wall and the container arrangement and the dispenser is configured to dispense substances after pressure loading the outer shell, wherein the container arrangement includes at least two containers and a common dispensing head are connected with each other pressure tight in at least one portion, and wherein at least one of the containers includes self-closing filling valves which are configured to be openable by pressure during filling the at least two containers.

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

A cap assembly for a refill capsule and associated refill system is disclosed. The cap assembly (200) comprises an inner wall (202) defining a conduit (203) through the cap assembly (200) and an outer wall (204) surrounding the inner wall to form a circumferential void between the inner and outer walls (202, 204). A connecting wall joins the inner and outer walls (202, 204). The cap assembly (200) further comprises a closure member (208) which is sealed to the inner wall (202) with a peripheral frangible connection (210). The frangible connection (210) is disposed between a first peripheral recess (222) formed between the inner wall (202) and the downstream side (208b) of the closure member (208), and a second peripheral recess (224) between the inner wall (202) and the upstream side (208b) of the closure member (208).
