A pump for dispensing a fluid, has a pump head, a piston with a piston body, a pump chamber provided by a pump chamber part, an inlet valve and an outlet valve. The piston body is moveable relative to the pump chamber. The piston body is tube-like, providing a channel for delivering the fluid from the pump chamber via the outlet valve to an outlet opening in the pump head. The outlet valve is a valve body cooperating with a sealing rim formed by an opening in an outlet channel of the pump head. The piston body has a sealing lip for with an inner surface of the pump chamber body. The pump head is moveable relative to the piston body providing an opening stroke for the outlet valve, wherein the valve body moves axially in the opposite direction into a part of the outlet channel above the valve body.

A dispenser for discharging flowable compounds has a reservoir for holding the compound and a dispensing pump. The dispenser has a longitudinal axis. The dispensing pump has an inflow and an outflow channel, a pumping chamber which is delimited on the inflow and outflow sides by valves, and a head piece. The head piece has a dispensing opening. A pumping part can be moved relative to a cup part against an elastic force of a restoring device in order to achieve a pumping stroke, and the head piece is coupled to the pumping part with respect to motion such that a motion of the head piece from a completely depressed position to a reachable extension height corresponds to the pumping stroke. A variable limiting device is provided for variably limiting the pumping stroke and a change in the pumping stroke corresponds to a change in the extension height.

A liquid pump is provided, including a pump body and a valve seat, the pump body is an integral part integrally formed by the same material, the pump body includes a shell with a hollow pump cavity and an elastic valve plate disposed at a bottom end portion of the shell, and the elastic valve plate is provided with a valve passage, the valve seat is disposed below the elastic valve plate in a fitted manner, the valve seat includes a valve body with a liquid flow passage, and the top of the valve body is provided with a seal structure that can be fitted with the elastic valve plate in a sealed manner. The product assembly is more convenient, product durability is high, and all components can be fully recycled.

A dispenser for dispensing flowable, for example liquid or pasty, compounds, includes a storage tank for the compound and a pump chamber, and also includes a dispenser head, wherein the dispenser head has a dispensing mouth and the dispenser head can be pressed down against a stop in the direction of a vertical axis of the dispenser to perform a pumping operation, wherein the stop is adjustable in terms of its height. In order to give a dispenser of the kind in question an advantageous design, in particular with regard to handling, the stop is formed by an outwardly exposed sliding track that can be rotated around the vertical axis, against which a projection that protrudes radially outward on the dispenser head comes to a stop when pressing down.

A set including a pump dispenser for discharging pharmaceutical or cosmetic liquids and an external evaluation unit, which is designed to be exchangeable so that, after the pump dispenser has been emptied, the evaluation unit can be attached to a new pump dispenser. The evaluation unit can be attached to the discharging head of the pump dispenser such that the evaluation unit detects an actuation button and can be partially displaced with same. The evaluation unit can alternatively have a receiving container which is open on at least one side and into which the pump dispenser can be inserted and the force application of which is detected on actuation.

A wobble plate for a sequentially activated multi-diaphragm foam pump includes three or more wings, a wobble plate shaft, and an aperture located in each of the three or more wings. A first wing is configured to have a first distance from first contact surface of a first pump diaphragm. A second wing is configured to have a second distance from a first contact surface on a second pump diaphragm, and a third wing is configured to have substantially the second distance from a first contact surface on a third pump diaphragm.

A dispenser for dispensing liquid or pasty materials has a head part with a dispenser opening. The dispenser opening is formed by lip sections which lie directly on top of each other. A lip section for opening the dispenser opening can be lifted from the other lip section by means of a lifting part that engages on the lip section. The lifting part acts on the lip section with a loading direction that runs transversely to a dispensing direction of the material.

A discharge head for a liquid dispenser having a base, an actuation handle, a liquid inlet and a discharge opening. The discharge head has a pump mechanism which conveys liquid from a liquid store to the discharge opening. To control liquid to be discharged and/or inflowing air, the discharge head has a valve with a valve flap which closes a valve channel and transfers to an open position by a positive pressure that exceeds a threshold positive pressure. The discharge head has an effector element bearing on the handle and the base, which deforms when the handle is pressed down. The valve flap is designed and attached to the effector element such that the deformation of same acts on the valve flap so that the threshold positive pressure, beyond which the valve flap leaves its closed position, is at least 10% lower in an actuated end position than in a non-actuated end position.

A set including a pump dispenser for discharging pharmaceutical or cosmetic liquids and an external evaluation unit, which is designed to be exchangeable so that, after the pump dispenser has been emptied, the evaluation unit can be attached to a new pump dispenser. The evaluation unit can be attached to the discharging head of the pump dispenser such that the evaluation unit detects an actuation button and can be partially displaced with same. The evaluation unit can alternatively have a receiving container which is open on at least one side and into which the pump dispenser can be inserted and the force application of which is detected on actuation.

Provided is a fluid container including: a container main body, of which one side is open, configured to store a fluid; a housing having an outlet provided at one side and in which the container main body slides in a longitudinal direction; and a pump module coupled to the open one side of the container main body and configured to discharge the fluid to the outlet by sliding the container main body.
