A press pump (1) comprises a press pump body 10) in which a spring tube (20) is provided, a spring (21) is contained within the spring tube (20); a cylinder head (30) mounted on the press pump body 10) and including a internal bore (31); a press head (40) including a pressing portion (41) and a rod portion (42), the rod portion (42) is fit within the internal bore (31) of the cylinder head (30), and a lower portion of the rod (42) engages with the spring (21), so that the spring (21) applies an upward bias force on the press head (40); and a piston (50) connected to the press head (40) and is slidably and sealingly engaged with the internal circumference of the press pump body 10). The press pump (1) can use a spring (21) with relatively small size, while meet the requirement of large displacement, thus reducing manufacturing cost, and also can prevent contact between the product and the spring (21), avoiding negative effects between them.

An anti-backflow extrusion liquid container includes an elastic container for storing and extruding liquid, a spraying tube inserted into the elastic container, a first one-way valve for controlling the opening and closing of the spraying tube, and a second one-way valve for adjusting the air pressure in the elastic container. The first one-way valve is disposed in the middle of the spraying tube, and the second one-way valve is disposed at the bottom of the elastic container. The disclosure not only prevents the liquid in the guide tube from flowing back into the bottle body during the restoring process of the bottle body and thus avoiding the liquid in the bottle body from being contaminated, but also enables the bottle body to be restored quickly after pressing and thus prolonging the service life of bottle and improving work efficiency.

A discharge head for a liquid dispenser having a base and a push actuator. The discharge head has a pump device, which has a malleable pump chamber component open on both sides, fastened to the base and to the push actuator and encloses a pump chamber having a variable volume. The pump device has inlet and outlet valves. The discharge head has a ventilation opening and a ventilation valve. The ventilation valve on the base has a peripheral valve web raised via a surrounding cover wall of the base and the inside of which forms a peripheral valve surface. To ensure a reproducible behavior of the ventilation valve, a reinforcement structure is provided on the cover wall in the form of a peripheral reinforcement web, and/or the peripheral valve web is designed as part of a sleeve-like structure, which forms the peripheral valve web above the cover wall.

A dosing dispenser for dosing of at least one material component respectively received in a receiving compartment. In a dosing dispenser for the discharge of material components that has a double-walled structure of the pump unit, a ventilation path is provided leading from the outer environment to the receiving compartment through the pump unit.

A reservoir for a fluid product having a container defining a neck and a mounting part mounted on the neck, the mounting part forming a basket arranged at the neck and a plunger tube, which extends from the basket into the container, the plunger tube being initially sealed by a sealing member. The reservoir further has an insert located in the basket and having a piercing element capable of moving between an initial position, in which the sealing member forms a seal, and a final position, in which the sealing member is displaced by the piercing element to an open state.

A packaging for storing and dispensing fluid contents comprises a body defining a reservoir, wherein the body comprises a base with an aperture defined therein, a receptacle configured to store the fluid contents therein is received within the reservoir of the body, and a one-way valve positioned in the aperture. The packaging further comprises an actuator comprising a channel and an opening configured to dispense the fluid contents out of the packaging. An intermediate connecting member comprising a first connection portion configured to engage the actuator, a bellow, a second connection portion configured to engage the body, and a duckbill valve integrally formed thereon extends between the body and the actuator. The duckbill valve is aligned with the channel, and the fluid contents of the receptacle flow out of the duckbill valve, through the channel, and out of the opening upon a user applying an input to the actuator.

A sprayer system includes a sprayer head, at least two reservoirs, and a gripping portion. The reservoirs hold constituent components of a product. The product is emitted from a nozzle included in the sprayer head. The emission of the product results in the depletion of the components of one of the reservoirs to a greater extent than the remaining at least one reservoir and changes the center of gravity of the sprayer system.

A soap dispenser including a rigid cartridge, an inverted dispensing pump, a collar carrying a lever for actuating the pump, and a venting system for equalizing the air pressure in the rigid cartridge, wherein the rigid cartridge and the collar cooperate to removably attach the soap dispenser to a wall-mounted bracket, and further wherein at least the rigid cartridge is disposable and can be made of a recyclable and/or biodegradable material.

Disclosed in the present invention is a pump type dispenser which includes a pump held by a mouth portion of a container and configured to suction and pressure-feed a content liquid in the container, and a nozzle head having an internal passage through which the pressure-fed content liquid passes and driving the pump by being repeatedly pushed down and restored. The internal passage includes a vertical passage, a lateral passage, and a protrusion protruding toward an inner side in a joining portion between the vertical passage and the lateral passage, and a dispensing member disposed in the lateral passage includes a recessed portion which engages with the protrusion to prevent separation from the lateral passage.

A container includes a reservoir holding a non-pressurized product. A metering device and valve assembly are within the reservoir. The valve assembly includes a product intake conduit and a spring biased valve stem. The valve stem is at least one of an upwardly extending conduit or reciprocating conduit, which is in fluid communication with the product intake conduit.
