Dispenser device for liquids, comprising: a dispenser head (1); a replaceable, flexible receptacle (2), containing the liquid to be dispensed and which has a valve (21) provided with a seal (22) for opening and closing; a rigid container (3) for securing the flexible receptacle, provided with a mouth (32) for the mechanical coupling of the dispenser head (1) and of means (33) for the coupling and securing of the valve (21) of the flexible receptacle (2) in a position facing the mouth (32) of the rigid container (3); and a hydraulic coupling part (4) of the dispenser head to the flexible receptacle, which is automatically coupled to and decoupled from the seal (22) of the valve (21) and displaces it towards an open position and towards a closed position when the dispenser head (1) is coupled to and decoupled from the rigid container (3), respectively.

A liquid storage and delivery apparatus comprising a combination of liquid reservoir, valves, a quick release connector, a liquid pump, a pump power switch, a pressure sensor, and associated hardware. This liquid from this apparatus can be discharged by electric pumping alone, high internal gas pressure alone, or by electric pump augmented by high internal gas pressure.

A modular frame for a backpack sprayer system includes a frame plate having a front surface, a back surface and first and second side edges. A first receiving channel is located along the first side edge and a second receiving channel is located along the second side edge. A support member has a first arm which is received within the first receiving channel and a second arm which is received within the second receiving channel. A stand portion extends at an angle relative to the first and second arms. A mounting member is coupled to the front surface of the frame plate and mounts a tank and a pump unit thereon. The mounting member includes opposing left and right sides, a planar top face and a front face including a concave portion to receive at least a portion of one or both of the tank and the pump unit.

A sustained duration trigger sprayer includes a first vacuum formed by piston movement in a fluid cylinder which fills the sprayer for delivery of a fluid and a second vacuum formed between a vacuum piston connected to the fluid cylinder and a vacuum cylinder acts on the sprayer to disperse product when a discharge valve is opened.

The personal cooling misting system disclosed provides for a wearable fluid reservoir to contain a volume of misting fluid, and an electrically operated pump proximate to the reservoir to pump the misting fluid from the reservoir to a misting head. The misting head facilitates atomizing the misting fluid. The system further provides for feed tubing to direct the misting fluid from the reservoir to the pump, and distributive tubing to direct the misting fluid from the pump to the misting head. The system also includes a pump control to control at least one of a pressure and a flow rate of the misting fluid through at least one of the feed tubing and distributive tubing, and the system includes a programmable circuit board to facilitate system control via the pump control, as well as directing to the pump control a misting distribution pattern for at least one of a consistent or intermittent misting pattern.

A weighted multitube fluid dispenser designed to allow a user to efficiently dispense fluid stored in a bottle regardless of how they tilt the bottle. The weighted multitube fluid dispenser includes a bottle having an opening at a top end disposed opposite a bottom end and in communication with an interior designed to store liquid therein. A spray head is designed to secure overtop the opening via a rim. A hose extends from the spray head and splits into a plurality of tubes, each tube having an aperture at one end with a weight affixed. The spray head includes a nozzle in communication with the hose, and a trigger in communication with the nozzle. Thus, activating the trigger causes fluid in the bottle to traverse the plurality of tubes and exit through the nozzle, allowing the user to dispense the fluid regardless of how the bottle is tilted.

A connecting structure for a liquid container includes a receiving groove. The liquid container having a suction tube is disposed in the receiving groove. A top end of the receiving groove is engaged with a connecting base. A front side of the connecting base is pivotally connected to a locking assembly protruding frontwards. A liftable base being movable along a top-bottom direction and a front-rear direction is disposed in an inner side of the connecting base, and has a bottom frame engaging with a sleeve that is for being connected to and communicating with a liquid pipeline and fits around the suction tube. Two extending arms extending frontwards out of the bottom frame are pivotally connected to the locking assembly. A left side and a right side of the bottom frame are pivotally connected to two swinging arms that extend backwards and are pivotally connected to the connecting base.

The disclosure relates to an extended-range spray applicator, and methods of making and use thereof, for dosing vaccines and/or probiotics to avian animals at a distance.

The invention relates to a device and method for applying a spraying means using a portable spraying device.

A pump for supplying liquids or gases, comprising: a mechanism of suction/discharge consists of a handle, fasteners and injection pump, a piston, a dispenser, a body of valves, two valves, pump a shirt, a piece containing a pumping chamber, at least two primary and secondary supports, bridge pump with at least two fastening means of conduit and oppressive cam piston articles attachments or pump and tank securing means; a container of liquid or gas should be projected by suction/expulsion; a hose transports.
