A fluid container is disclosed with a cap body made of rigid or semi rigid material and a valve body disposed within the cap body and movable between and open and closed position. The valve body is made of a semi flexible semi rigid material that has a coefficient of thermal linear expansion that is smaller than that of the cap body. The cap body and nozzle valve are configured with three different hermetic seals to counteract the effects of exposure to heat and cold over time and thereby extend the useful life of the cap and valve.

A measuring a closed-loop fluid transfer system is provided that includes a measuring adapter having a first end and a second ends, and a chamber located there between and configured to hold a volume of fluid. The measuring adapter includes a first receiving valve assembly located at the first end of the measuring adapter. The first receiving valve assembly includes a receiving valve member, at least a portion of which is separable from a portion of the first receiving valve assembly. This creates an opening that provides fluid communication to the chamber when a force is exerted on the receiving valve member of the first receiving valve assembly. A second valve assembly located at the second end of the measuring adapter includes a valve member. At least a portion of the valve member of the second valve assembly is separable from a portion of the second valve assembly to create an opening that provides fluid communication to the chamber.

A system and method for dispensing fluids is introduced. A preferred embodiment comprises a sealed tank, a bag containing fluid inside the sealed tank, an outlet for dispensing the liquid in the bag, and a pressure generating device to create pressure in the sealed tank.

A stopper for a container providing evidence of first opening includes an upper part with a protection cap closable on a pouring element and a ridged lower part with an upper hollow cylindrical portion disposed inside the pouring element and a lower cylindrical portion of larger diameter that is internally threaded. A frangible label is positioned between the protection cap, and a security ring is connected with the upper and lower parts with frangible bridges. An annular security crown is connected to the lower part of the stopper by frangible bridges and a cam arrangement, coaxially coupled between an outer surface of the upper hollow cylindrical portion and an inner surface of the pouring element, causes their translation and rotation. The pouring element has a duct passage and a coaxial island shutter which cooperates with a central hole in the upper hollow cylindrical portion of the lower part.

Embodiments of the present disclosure generally relate to caps, closures, seals, and containers, and control of flow of fluids. Certain embodiments can be used with fluids related to machinery, for instance, engine oil, brake fluid, coolant, transmission fluid, and power steering fluid. Certain embodiments of the present disclosure effectively hold and transfer a fluid or a fluid substance, further being able to open, close, and regulate fluid flow. Embodiments include a single piece tubular component that includes a cap interiorly attached to such tubular component with ribs, and a container having a tapered end. In certain embodiments, a nozzle collar having a tapered end is adapted to attach to a container.

A dispenser cartridge for use in a dispenser arrangement for introducing at least one dispensed substance into a liquid, includes an enveloping element with a continuous central space and with at least two openings for the entry and exit of the liquid respectively, wherein the dispensed substance is provided in the central space wherein first and second sealing means are provided which seal the openings completely in an initial configuration, wherein the sealing means can be brought into an operating configuration in which a flow path through the enveloping element is opened for the liquid.

A system and method for dispensing fluids is introduced. A preferred embodiment comprises a sealed tank, a bag containing fluid inside the sealed tank, an outlet for dispensing the liquid in the bag, and a pressure generating device to create pressure in the sealed tank.

The present invention is directed to a closure for an outlet opening of a container comprising a first component which snaps onto an outlet opening and provides a seal for an outlet opening said first component snaps with a second component of said closure; wherein the first component comprises one or more rails to enable stability of the assembly and defines the direction of movement of the second component relative to the first component; a second component comprising a dispensing orifice of said second component, said second component, snaps with said first component; wherein the second component comprises ribs which engage the rail(s) of said first component; a dispensing orifice positioned directly adjacent to the open portion of the container body; wherein one or more directions of the movement of the second component relative to the first component are independently controlled by rails and ribs.
