Apparatuses and methods of operating the same are described. An apparatus may include a lower compartment, a baffle, and an upper compartment. The lower compartment may form a lower cavity to hold a liquid. The baffle may include a channel connecting the lower compartment to an upper compartment, where the channel provides a first passageway for liquid to pass between the lower compartment and the upper compartment. The baffle may also include a baffle passage defining an opening through a middle section of the liquid container between the lower compartment and the upper compartment. The upper compartment may form an upper cavity to hold the liquid.

The present disclosure is directed to devices for dispensing liquid, especially fuel. In one embodiment, a device for dispensing fuel includes a spout for pouring liquid fuel, an annular fitting including a chamber formed therein. A sealing surface, a stopper, and spring may be disposed within the chamber. The annular fitting may be attached to the spout. The annular fitting may be configured to mate with a portable fuel canister. The fitting may include sidewalls forming a channel for liquid fuel, an outer wall enveloping a portion of the sidewall forming a chamber proximate the liquid channel, and an atmospheric orifice formed in the outer wall. The sealing surface may be disposed proximal the orifice. The spring may be configured to bias the stopper into contact with the sealing surface such that the chamber is in selective pressure-dependent fluid communication with an atmosphere outside the device.

Liquid container nozzles including a valve handle, valve body, spool, and spout assembly, where the valve body may move slidingly into the valve handle over the spool to control the flow of liquid through the nozzle. Liquid flow may be controlled by adjusting the position of the valve body in relation to the valve handle and spool using varying force or pressure. The spool may include one or more holes to control the flow of liquid. In some examples of the invention, the spool may narrow in an S-shaped fashion, and the holes of the spool may be located on a portion of the spool that narrows to form S-shaped holes. These holes may swirl liquid as it is poured from the nozzle to create a more uniform flow.

Method and system for measured dispending of a liquid to a target reservoir. An oval gear flow meter provides two pulses from different magnets. A pipe subsystem allows liquid from an above-ground reservoir measured through the oval gear flow meter to be controllably dispensed using a controllable valve. A processor module, upon receipt of a start-signal, opens the controllable valve and, until receipt of a stop-signal, computes a volume of the liquid dispensed by the system into the target reservoir by counting the pulses as a first and second counts. An adjustable volume-per-count value is computed with the count(s) to obtain the volume of liquid dispensed. The processor generates an error when a difference between the two counts is greater than a predetermined threshold set considering a target precision setting for the dispensing system.

The present invention solves some of the problems of the prior art by providing a method, system and apparatus for readily refilling the reservoir of a smoking-substitute device with liquid from a dispenser. The method, system and apparatus of the present invention prevents liquid from being dispensed until the dispenser is securely and sealably engaged to the smoking-substitute device, provides independent liquid and gas pathways between the dispenser and reservoir, and substantially alleviates the problems of spillage and/or leakage when dispensing liquid from the dispenser into the reservoir of the smoking-substitute device.
