The invention is directed to a dispensing device comprising a rigid container, a flexible bladder, and a rigid stopper. The container is adapted to contain a product to be dispensed. The flexible bladder is disposed below and in fluid communication with the container. The bladder comprises a top end, a sidewall extending downwardly from the top end and terminates in a spout. The bladder is in a liquid tight engagement with the container and the product contained in the container is adapted to flow into the bladder. The rigid stopper is disposed within the flexible bladder and comprises a top end, and at least one sidewall extending downwardly from the top end, and terminates in an open bottom end. The stopper comprises a plurality of through holes.

A spray nozzle chip comprising: a first layer provided with a first layer orifice, and a mechanically flexible nozzle layer provided with a nozzle orifice, wherein the first layer has a valve seat arranged aligned with the nozzle orifice, wherein the spray nozzle chip has a valve functionality obtained by movement of the nozzle layer relative to the valve seat due to pressure changes, and wherein the nozzle layer is arranged at a distance from the valve seat when the nozzle layer is in a default non-pressurised state, whereby a gap with a gap length (L) is formed between the nozzle layer and the valve seat, wherein the gap length (L) is smaller than a dimension of a specific bacterial type, to thereby seal against bacterial ingrowth through the nozzle orifice of the specific bacterial type.

A gas-filled resilient body and uses thereof are described. The gas-filled resilient body may be used as a valve member, as a spring or as a gas-propelled dispenser.

An outlet valve for a dispensing nozzle comprising a first valve component constructed and arranged to be received by the dispensing nozzle and a second valve component constructed and arranged to cooperate with the first valve component. The first valve component and the second valve component define a normally-closed flow interface.

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 air pressure in the rigid cartridge. The rigid cartridge and collar cooperate to removably attach the soap dispenser to a wall-mounted bracket, in which at least the rigid cartridge is disposable being made of recyclable and/or biodegradable material.

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 portable pump by which liquid may be horizontally pressed out, comprising a liquid storage container, a pump head being provided at a side of the liquid storage container, and a liquid suction device that is connected to the pump head being provided within the liquid storage container. The liquid suction device comprises a liquid suction chamber, a spring, a piston, and a liquid outlet pipe that is connected to the pump head. The liquid suction chamber is provided with a liquid inlet pipe and a fixed end of the spring, check valves being provided within the liquid outlet pipe and the liquid inlet pipe. The piston is sleeved with the liquid outlet pipe and provided with a through hole that matches an opening of the liquid outlet pipe. The pump can comprise a locking seat on the side of the liquid storage container that matches a pump head cover.

A dispensing system (2000), includes a container (900) containing a flowable base formulation (910) to be dispensed, an additive mixing device (2004), and an actuable pump engine (2002) which draws the flowable base formulation from the container and pumps it through the mixing device. The additive mixing device includes a body (2022) with an internal cavity (2052), an additive ingredient (2054) within the cavity, and a flow path/mixing chamber (2058) between an input and an output. With each pump of the device (2004) the additive ingredient is introduced into, and mixed with, a flow of the base formulation traveling through the mixing device. Multiple additive mixing devices (2004) may be interchangeable for different formulations, and the mixing devices may be refillable.

A liquid dispensing system includes at least one container for storing the liquid to be dispensed, the at least one container having a neck defining a fill opening for the liquid. The system includes a liquid dispensing device releasably connectable to the at least one container, an exchangeable cartridge for an additive to be mixed with the stored liquid, where the cartridge is accommodated in the neck, and a piercing member for opening the cartridge. The cartridge includes a one-piece hollow body filled with the additive and with a pressurized gas, and the piercing member is arranged to pierce a wall of the hollow body. A method of dispensing a liquid by using the liquid dispensing system, and a cartridge for use in the liquid dispensing system and/or method.

The present invention relates to a pump head that enables a metered dispensing of fluids. The present invention also relates to a metering apparatus that can, for example, be configured as a squeeze bottle, wherein the metering apparatus comprises a pump head in accordance with the invention.
