A leash training device embodying a non-invasive and non-threatening method of using the same to train a dog is provided. The leash training device may include a liquid sprayer having a housing forming a handle portion and a leash assembly. While grasping the handle portion so as to manage the dog on the other end of the leash assembly, the liquid sprayer is adapted so that the user may discharge a jet of liquid from a reservoir secured within the housing. The method includes discharging the jet at or on the dog engaged in bad behavior.

A liquid dispenser for dispensing in pharmaceutical liquids via a discharge or dispensing opening protected by a protective cap. The protective cap has a fastening part, designed for coupling to a housing of the liquid dispenser, and an inner part separate from the fastening part. The inner part, when the protective cap is in a fitted state, protects the discharge opening. The inner part is captively coupled to the fastening part by a coupling device, and the inner part is freely rotatable about a longitudinal axis of the protective cap in relation to the fastening part.

A piston pump with a piston chamber-forming body and a piston-forming element relatively coaxially reciprocally movable to dispense liquid and air from a discharge outlet, which the discharge outlet is fixed relative to the piston chamber-forming body.

A product dispenser is provided that includes a container within a shell, and a pump and insert for dispensing the product. A spring biases the container and pump away from the tip of the shell. The bottom of the container is pushed up relative to the shell to activate the pump, thereby dispensing the product.

A fluid substance dispensing device including a container provided with an opening providing access to the interior thereof, and a dispensing pump associated with the container to dispense a fluid substance, which may be contained inside the container, and a sealing element positioned between the container and the pump, the sealing element including a flange abutting with a clear surface of the container perpendicular to a longitudinal axis of the container: the sealing element furthermore includes a first tubular wall which extends inside the container and creates a seal one an internal surface thereof, the sealing element furthermore including a second tubular wall which extends inside the container 2 and creates a seal with an external cylindrical surface of a body of the pump positioned inside the container.

A fluid dispenser for containing and dispensing metered amounts of fluid that includes a reservoir for containing fluid and a chamber positioned substantially within the reservoir for containing a quantity of the fluid. The fluid dispenser additionally includes a piston that is moveable within the chamber to draw fluid into the chamber when the piston is moved in a first direction with respect to the chamber, and to discharge fluid from the chamber when the piston is moved in a second direction opposite the first direction. Further, the fluid dispenser includes a user-manipulatable control coupled to the piston and rotatable about an axis to select one of at least two different metered quantities of fluid to be dispensed. The user-manipulatable control is further movable to move the piston relative to the chamber along the axis to selectively dispense the selected metered quantity of fluid.

Automatic electric actuation of the pumping mechanism of a liquid dispenser apparatus is provided by configuring a hollow tube to cooperate with an electromagnetically driven actuator and further configuring the hollow tube to inter-fit with a stem of a liquid dispensing pump. Actuation of the actuator may, for example, drive the pump stem downwardly to cause a pumping action. Suitable actuators include, for example, solenoids, voice coil actuators and stepping motors.

A metering dispenser for simultaneously or selectively discharging two media, including an outlet opening, a first reservoir for a first medium, a first metering-conveyor device for conveying the first medium from the first reservoir, a second reservoir for a second medium, a second metering-conveyor device for conveying the second medium from the second reservoir, a mixing chamber arranged upstream of the outlet opening and in which the first medium, conveyed by the first metering-conveyor device, and/or second medium, conveyed by the second metering-conveyor device, is stored temporarily, and an output-conveyor device for conveying the medium or media from the mixing chamber to the outlet opening. The first metering-conveyor device has the form of a metering-pump device with a variable-volume metering chamber, an inlet fluidically connected to the first reservoir and having an inlet valve, and an outlet fluidically connected to the mixing chamber and having an outlet valve.

A single-hand pressed foam pump head comprises a pump filled with foam liquid or emulsion. A spring is provided inside the pump. The pump comprises a press head and a fixed outflow cap; the fixed outflow cap is provided with a vertical connecting tube and is connected to a connecting end of a bottle; the connecting tube has a foam or liquid channel. A top portion of the connecting tube is provided with a horizontal connecting channel. The horizontal connecting channel is connected to a vertical plugged-in tube. When the connecting tube is pressed downward such that the vertical plugged-in tube is inserted into an outflow chamber of the fixed outflow cap, the connecting tube and the outflow chamber are connected to each other to form a top outflow channel. The present invention is simple in structure, stable in function and convenient for people to use.

A piston pump with a piston chamber-forming body and a piston-forming element relatively coaxially reciprocally movable to dispense liquid and air from a discharge outlet, which the discharge outlet is fixed relative to the piston chamber-forming body.
