A container configured for housing a fluid. A compressible body disposed within the container for dispensing fluid. The compressible body is compressed by applying compression to the container. When the compressible body changes from a non-compressed state to a compressed state, the fluid within the container does not flow into compressible body and fluid within the compressible body flows out of the compressible body and when the compressible body changes from the compressed state to the non-compressed state the fluid flows into the compressible body.

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.

The present invention relates to a pump head with a specially configured elastic valve which enables secure closure of the pump head. It is ensured by the valve that complete emptying and, at the same time, secure closing of the pump head is ensured so that no residues of fluid to be metered remain in the storage state of the pump head. In addition, the present invention relates to a metering device which can be configured for example as squeeze bottle, as non-airless system or as airless system, the metering device comprising a pump head according to the invention.

A liquid soap dispenser includes a container having a flexible outer wall and including a quantity of liquid soap therein. The upper surface of the container can be moved between an upper position and a lower position but is spring biased into the upper position. A pump within said container pumps a portion of the liquid soap onto the upper surface when it is moved downwardly into its lower position. A normally closed valve at the bottom of the container opens to dispense liquid soap from the bottom of the container when the container is squeezed.

Dropper including a first element which may be associated with a container mouth, the first element including a support for an elastically deformable suction cap sealedly coupled to a pipette, a push button which slides axially in relation to the first element to compress the suction cap, a selector rotatably constrained to the first element, with one thereofi.e. either selector or push buttonbeing fitted with at least two grooves with different depths and with the otheri.e. either button or selectorequipped with at least one flap cooperating with grooves so, when the flap is associated with a groove, following rotation of the selector, button stroke length is limited to depth of the groove associated with the flap, to adjust the amount of a fluid suctioned and/or dispensed by the dropper, the first element and button torsionally coupled.

The technology provides a material dispensing device and a method of dispensing metered amounts of materials from collapsible material containers.

A liquid soap dispenser includes a container having a flexible outer wall and including a quantity of liquid soap therein. The upper surface of the container can be moved between an upper position and a lower position but is spring biased into the upper position. A pump within said container pumps a portion of the liquid soap onto the upper surface when it is moved downwardly into its lower position. A normally closed valve at the bottom of the container opens to dispense liquid soap from the bottom of the container when the container is squeezed.

A method of performing a measurement of an analyte in a sample using an automatic analyzer is provided. The automatic analyzer comprises: a cartridge for dispensing a fluid, a measurement unit for performing the measurement, a sample holder for receiving the sample, and a pump for pumping the fluid out of the cartridge and into the sample holder. The cartridge comprises: a rigid portion, a flexible bladder, and an outlet. The rigid portion comprises an opening, which is connected to an inner cavity. The flexible bladder seals the opening to form a fluid chamber from the inner cavity. The fluid chamber is at least partially filled with the fluid. The pump is connected to the outlet. The method comprises: placing the sample into the sample holder, controlling the pumping of the fluid from the cartridge into the sample holder, and performing the measurement of the analyte using the measurement unit.

A liquid dosing device for a container includes a dosing chamber having a front end and a back end. An outlet passage is located at the front end. A plunger is located in the dosing chamber, divides it in a front and a back space, and is moveable between a forward position in which the plunger closes off the outlet passage, and a backward position, in which the front space has a maximal volume. An inlet passage provides fluid communication between the front space and the container. A timer passage provides fluid communication between the container and the back space. A release passage, being greater than the timer passage, provides fluid communication between the back space and the container. A valve assembly at the release passage includes a valve seat located at the back end of the dosing chamber.

The invention relates to a closure assembly configured to be mounted on a neck of a container, which closure assembly includes a cap with a dispensing opening and a self-closing dispensing valve attached to the cap such that it is located adjacent the dispensing opening, and wherein the dispensing valve is a disc of foil material having a central valve area in which at least one self-closing slit is located and an annular peripheral attachment area extending around the central valve area, with which attachment area the dispensing valve is attached to the attachment area of the dispensing cap such that its central valve area aligns with the dispensing opening of the dispensing cap to close off that dispensing opening, and wherein an annular rib offsets the central valve area of the dispensing valve relative to a substantially flat attachment area of the cap.
