A liquid dispenser, having a large ring, a connecting cover, and a hollow pump frame, the pump frame is movably clamped to the interior of the large ring, the top of the pump frame extends to the outer side of the top of the large circle, a bottom protruding portion of the connecting cover extends into a top groove of the pump frame so as to be movably clamped thereto, a first air outlet is provided on both sides of the bottom of the connecting cover, and a second air outlet in communication with the first air outlet is provided to penetrate through the pump frame. The first air outlet, the second air outlet, the first liquid outlet, and the second liquid outlet can be opened and closed by rotating the connecting cover to change a position relationship between the connecting cover and the pump frame

Fluid product dispenser having a reservoir (R) with a threaded neck (R1) forming an external helical thread (R2), a closure element (T) having a threaded skirt (F1) forming an internal helical thread (F2), and a band (H) engaging around the threaded skirt (F1). The skirt has tabs (F11), each forming a segment (F21) of the internal helical thread (F2). The fastening member (F) has an angular indexing mechanism for positioning it with respect to the external helical thread (R2) with a determined angular orientation, and the segments (F21) of the internal helical thread (F2) of the threaded skirt (F1) come into corresponding threaded contact with the external helical thread (R2) of the neck (R1) in the final assembly position.

A fluid dispensing system including a fluid dispenser that is operable in a stand-alone mode, and a housing that is configured to removably receive the fluid dispenser for operation of the fluid dispenser in a housed mode. When the fluid dispenser is placed on top of a horizontal support surface for operation of the fluid dispenser in the stand-alone mode, a pump mechanism of the fluid dispenser is manually activatable to dispense an allotment of fluid by manually depressing an activation member of the pump mechanism. When the fluid dispenser is received by the housing for operation of the fluid dispenser in the housed mode, the pump mechanism is activatable by activating an actuation mechanism of the housing

An improved bag spreader and methods of the using the same. The bag spreader includes a bag that holds particulate material, a base removably coupled to the bag and including an exit opening to permit the particulate material to fall therethrough, an impeller below the base and configured to receive the particulate material leaving the exit opening and spread the particulate material, and a fastener circumscribing the base and securing the bag to the base. The methods include removably securing a bag to a base using a single cable tie, filling the bag with particulate material, and turning a hand crank causing the impeller to spin and spread the particulate material.

A trigger pump dispenser (10) comprising: a body (20); an outlet nozzle (35); a pump chamber (190); a piston (25) for defining a variable volume in the pump chamber (190) and movable between a retracted position of larger chamber volume and an inserted position of lesser chamber volume; a trigger (60) coupled with the piston (25) and movable from a starting position at which the piston (25) is in the retracted position and a depressed position at which the piston (25) is in the inserted position; biasing means (65a, 65b) is provided for biasing the trigger (60) towards its retracted position.

A same-hand, finger-mounted, and finger-operated hand sanitizer dispensing system with finger-mounted or with remote-mounted fluid reservoir, is disclosed herein. The system is operable without risk of cross-contamination, and is operable by the contaminated hand for self-decontamination. A dispensing pump is mounted on one finger and operated by another finger on the same hand. The dispensing pump draws sanitizer from a reservoir by way of a supply tubing. The reservoir can be mounted on the same finger as the pump or on another finger of the same hand.

The invention relates to a system for attaching a dispensing pump on the neck of a reservoir containing a fluid product. The system a sleeve with attachment means on the neck and hooking means of the pump, an articulation collar, the articulation collar and sleeve being mounted mobile with respect to one another between an end of motion position (P.sub.F) and a start of motion position (P.sub.I), a shrink ring configured to move along the articulation collar between a top disassembly position (P.sub.H), wherein the attachment means are free, and a bottom position (P.sub.B) of use, wherein the attachment means are engaged around the neck and wherein the start and end of motion positions (P.sub.I, P.sub.F) are arranged so that the articulation collar can go from the top disassembly position (P.sub.H) to the bottom position (P.sub.B) of use by a translational motion.

A nebulizer for nebulizing a fluid and a reservoir with a fluid are proposed. The reservoir includes a collapsible bag with the fluid, where the bag extends in a circumferential direction within the housing part and wherein the reservoir is manually rotated for tensioning the nebulizer.
