Machine (1) for distributing a product stored in a container (30) comprising a storage zone (2) delimiting locations (4) for housing a container (30), a metering station (5) delimiting a chamber (6) housing a support (7) for accepting a collecting vessel (33), this support (7) being positioned vertically in line with an opening (8) providing access to the chamber (6), which opening is arranged in an upper part (61) of the chamber (6), the machine (1) further comprising a system (10) for emptying each location (4) for housing a container (30) through the opening (8) providing access to the chamber (6), and a unit (14) for controlling the machine (1). The metering station (5) comprises a sensor (13) for detecting the presence of a collecting vessel (33) inside said chamber (6). The control unit (14) is configured to operate the machine (1) on the basis of data supplied by said sensor (13), and the metering station (5) is equipped with a circuit (15) for the circulation of gaseous fluid providing communication between the chamber (6) and the outside of said chamber (6) through a forced circulation of air.

Fluid storage and dispensing systems and processes involving various structures methods for fluid storage and dispensing, including, pre-connect verification couplings that are usefully employed with fluid storage and dispensing packages to ensure proper coupling and avoid fluid contamination issues, empty detect systems (e.g., monitoring pressure of dispensed liquid medium to detect pressure droop conditions) useable with fluid storage and dispensing packages incorporating liners that are pressure-compressed in the fluid dispensing operation, ergonomically enhanced structures for facilitating removal of a dispense connector from a capped vessel, cap integrity assurance systems for preventing misuse of vessel caps, and keycoding systems for ensuring coupling of proper dispense assemblies and vessels. Fluid storage and dispensing systems achieve zero or near-zero headspace character, and prevent or ameliorate solubilization effects in liquid dispensing from liners in overpack vessels.

Disclosed herein are embodiments of liquid dispensing container preferably configured as portable, handheld liquid dispensing containers. These liquid dispensing containers possesses a vent structure that provides improved liquid dispensing along with simplified vent construction and container integration. In these regards, these liquid dispensing containers advantageously overcome one or more shortcomings associated conventional liquid dispensing containers and other types of containers.

A flow-through pressure-vacuum valve includes a valve body having a tank-side opening and a vent-side opening. A pressure relief valve (e.g., a ball held in a corresponding seat by gravity) is positioned within a first passageway through the body. The ball is moved from the first valve seat to open the first passageway when pressure at the tank-side opening exceeds pressure at the vent-side opening by a predetermined pressure differential. A vacuum relief valve is positioned within another passageway (e.g., a serpentine passageway). The vacuum relief valve (e.g., also a ball held in a corresponding seat by gravity) is positioned within the serpentine passageway. Analogously, the ball is moved from the valve seat to open the serpentine passageway when pressure at the tank-side opening is less than the pressure at the vent-side opening by a predetermined pressure differential.

Ullage float assemblies for fuel tanks are disclosed including a guide member with a retaining element mounted to a valve body which includes a first valve port and a second valve port in fluid communication. Methods of preventing spillage of fuel from a fuel tank during a refueling and a diurnal fuel volumetric expansion event are also disclosed. The assemblies and methods.

Exemplary sanitary soap refilling systems and methods are disclosed herein. An exemplary refill refilling system includes a housing, a pump located within the housing, and a bulk storage tank connector. The bulk storage tank connector having a liquid outlet and an air inlet. A liquid inlet conduit is in fluid communication with the pump the liquid outlet. A refill connector is included. The refill connector has a liquid inlet and an air outlet. The refill connector air outlet and the bulk storage tank connector air inlet are in fluid communication with one another. The refill liquid inlet is in fluid communication with the pump.

A reservoir-based storage and delivery system has a reservoir body equipped with a top assembly, a bottom assembly and a piston assembly. The contents of the reservoir are allowed to expand and contract during the thermal cycle due to the ability of the piston assembly to float within the reservoir, which eliminates the need for dead head space.
