The disclosure discloses a dual-spring all-plastic vacuum pump which includes a base and a pressing head. A feeding hole is formed in a bottom of the base, an accommodating cavity is defined by assembly of the pressing head and the base, the feeding hole is in communication with the accommodating cavity, and a limiting cover, a plastic one-way spring, a discharging member and a plastic reset spring are disposed in the accommodating cavity. The limiting cover surrounds the feeding hole, a guide hole in a top of the limiting cover is in communication with an interior of the limiting cover, the plastic one-way spring is clamped between the base and the limiting cover, a fixed end of the plastic one-way spring is in connection and communication with the feeding hole, a stressed end of the plastic one-way spring is in communication with the guide hole, and the fixed end and the stress are opposite. The discharging member is disposed between the pressing head and the limiting cover, the discharging member penetrates through the guide hole and is in communication with the stressed end, and the discharging member is configured to receive materials to the pressing head for output. The plastic reset spring is clamped between the discharging member and the limiting cover. Pressing of the pressing head is configured to push the discharging member to compress the plastic one-way spring. By means of the solution, a metal spring is replaced with a plastic spring, and the problem that an existing pump head is inconvenient to directly recycle is practically solved.

A liquid dispenser apparatus having a back plate, a housing, and a liquid dispenser unit, the housing and backplate being constructed to attach to one another, the housing and liquid dispenser unit being constructed such that the liquid dispenser unit is removably installable into the housing and pivotally mounted with respect thereto such that the dispenser unit can be pivoted to a selected acute filling angle with respect to the housing.

A dispensing pump capable of withstanding the rigors of “e-commerce” shipping conditions is described. The pump dispenser is integrated with the container's closure. The pump includes a lock-down mechanism to prevent the pump actuator from extending during shipment, while a vented chaplet and an optional beaded seal proximate to the dip tube connection ensure that fluid cannot leak out of the container or the pump.

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.

Disclosed is a tubeless dispenser container. A tubeless dispenser container according to one aspect of the invention is a tubeless dispenser container for dispensing a content held in a filling space and includes: a bottle part in which the filling space is formed and which has a supply hole, for allowing a flow of the content, and an air hole, for allowing an inflow of air, formed in its upper surface; a connector part coupled to an upper portion of the bottle part to spatially separate the supply hole from the air hole; and a pump part that is secured to a designated position of the connector part and configured to suction and dispense the content supplied through the supply hole, where a supply channel connecting a lower portion of the filling space with the supply hole may be formed in the bottle part.

[Object] To provide a trigger-type pump dispenser that makes it possible to prevent an out-of-nozzle squirting phenomenon that occurs at a final stage of sucking up of liquid out of a vessel into a cylinder. [Solution] A trigger-type pump dispenser A includes a handle structure 1, a nozzle base structure 2 attached to the handle structure 1, a trigger 3, a cylinder structure 4, a cap 5 by which the cylinder structure 4 is held down and attached to the mouth of a vessel, a piston structure 6 that slides inside the cylinder structure 4, an inverted-mortar-shaped lip 61 formed in the piston structure 6, a spring 7 that springs the piston structure 6, a valve case 8 attached to the nozzle base structure 2, a mortar-shaped valve seat 81 formed in the valve case 8, a leak valve 9, attached to a bottom part of the cylinder structure 4, that has a bulging portion 91 at a tip thereof, a first valve FV, and a second valve SV. A movement of the piston structure 6 from top dead center to bottom dead center causes liquid in the cylinder structure 4 to be discharged from a nozzle orifice N. The bulging portion 91 at the tip of the leak valve 9 is disposed to pass through the inverted-mortar-shaped lip 61. A through-hole diameter D1 of the mortar-shaped valve seat 81 of the valve case 8 is smaller than a nozzle orifice diameter D2.

Various dispensing devices, such as foaming soap pumps, are disclosed. The soap pump can include a fluid storage unit and a fluid handling unit. The fluid storage unit can include a reservoir that is configured to hold a quantity of product, such as liquid soap. The fluid handling unit can include a pumping assembly and dispensing assembly. The soap pump can be configured to withdraw liquid soap from the reservoir, convert the liquid soap to foamed soap, and dispense the foamed soap from the discharge assembly.

The present disclosure relates to a two-way pumping device for consumption of a residual amount of a liquid. The two-way pumping device includes a vessel, a body portion including first and second chambers for storing a liquid, a suction pipe extending to the outside of the body portion, a first bearing for opening and closing the suction pipe, a pump portion including a head portion protruding outside the body portion, a first piston slidably moving in the first chamber, a second piston slidably moving in the second chamber, a first discharge portion that discharges a fluid in the first chamber to the outside, a second discharge portion that discharges a fluid in the second chamber to the outside, a spring that applies an elastic restoring force to the pump portion, and a suction portion capable of causing a liquid to flow into the second chamber.

Described is a dispenser for dispensing a fluid, made of plastic material, including: —a ring nut having an inner cylindrical wall equipped with partial grooves; —a concertina-like deformable element, defining a return spring of the dispenser and including a cylindrical lower projection equipped with relative partial grooves; —a ring designed to define with the ring nut a locking system designed to define an operating configuration and a non-operating configuration of the dispenser in such a way as to pull the concertina-like deformable element in such a way as to align the partial grooves of the cylindrical wall of the ring nut and the partial grooves of the concertina-like deformable element.
