A trigger sprayer for connection to a container or liquid product which is to be dispensed is disclosed. The trigger sprayer includes a trigger body with a first engagement member and a nozzle with a second engagement member. The first engagement member is constructed and arranged to receive the second engagement member. The second engagement member is moveable relative to the first engagement member between a first position and a second position. Movement of the second engagement member relative to the first engagement member between the first and second positions encounters a region of increased resistance.

[Object] To provide a push-type dispenser that is simple in structure and yet capable of surely preventing liquid leakage even when it topples over. [Solution] A push-type dispenser 100 includes: a cap section 1 that is attachable to a container X containing a liquid; a housing section 2 fixedly fitted in a central portion of the cap section 1; a piston section 3 that is slidable in the housing section 2; a nozzle head section 4 fitted on an upper portion of the piston section 3; a spring section 5 housed in the housing section 2 and configured to bias the nozzle head section 4 upward; a tube section 6 attached to a lower portion of the housing section 2; an F valve A housed in the housing section 2 and configured to open and close a flow channel through which the liquid flows from inside the tube section 6 into the housing section 2; and an S valve B housed in the piston section 3 and configured to open and close a flow channel through which the liquid flows inside of the piston section 3, wherein the liquid is ejected from inside the housing section 2 by moving the nozzle head section 4 downward, the piston section 3 has a through-hole 34, provided in a side surface of the upper portion of the piston section 3, through which the liquid flows, and the through-hole 34 is opened and closed by rotating the nozzle head section 4 circumferentially with respect to the piston section 3.

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.

A dispenser pump is constituted by a closure body (2), a diaphragm body (3) which forms a pump chamber with the closure body and optionally a top actuator (4) for pressing the diaphragm body (4). The diaphragm body has a deformable wall (35) formed integrally in the same polymer as its annular mounting portion (31). An inlet valve (5) through the floor (21) of the closure body has a flap (52) which is formed and hinged integrally with that floor (21). An outlet valve may also be formed in the same polymer, either integrally with the diaphragm body or as a separate component. The deformable wall of the diaphragm body is shaped to generate a restoring force itself without a separate spring, so that the entire pump may be made from the same polymer e.g. polypropylene and without metal components.

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.

A dry powder spray bottle includes a bottle body. The bottle body includes an outer bottle and an inner bottle, a piston and a one-way air inlet valve are sequentially arranged between the inner bottle and the outer bottle, a powder storage cavity is formed above the piston, and an airbag structure is formed between the one-way air inlet valve and the outer bottle. A rotating powder stirring mechanism is provided between the inner bottle and the outer bottle. A one-way valve is provided in the powder stirring mechanism, and when the head cap is pressed, the one-way valve opens, and gas in the airbag structure is delivered to the inner bottle through the one-way valve and sprayed out from the head cap together with dry powders, and a sealing mechanism which can close a powder outlet passage is provided between the head cap and the inner bottle.

The multi-nozzle multi-container fluid spray device includes multiple, for example, three, containers. Each container may hold a different liquid which the user may dispense simultaneously, in a desired combination, or individually. The containers are connected to each other and to a spray handle and spray head in a reversible manner. The spray head includes multiple nozzles, with each nozzle being designed to independently turn on, off, or to dispense a liquid spray at a desired density of liquid particles. The multiple pumps and hoses may be housed within the spray head. Each of the hoses extends from a single pump into one of the containers. Each pump is designed to dispense a liquid from one of the containers through a single nozzle. If a nozzle is turned off, the pump connected to that nozzle does not dispense liquid from the container with which it is connected.
