Estimating the term…
The present invention relates to a system and assembly for refilling a reservoir with liquid dispensed from a dispenser, in particular, but not exclusively, to a system and assembly for the substantially leak-free refilling of the reservoir of a smoking-substitute device with a liquid comprising nicotine from a refill dispenser. The assembly is configured to provide a gas communication pathway through the assembly and physically separate from the liquid communication pathway for venting gas from an end of the assembly proximal the first aperture to an exterior of the assembly responsive to the movement of the assembly to the secured and open configuration, the assembly configured to close the gas communication pathway in the unsecured and closed configuration
An assembly for controllably transferring liquid therethrough, said assembly moveable between an unsecured and closed configuration in which liquid communication is restricted between a first and a second aperture disposed at respective ends of the assembly, and a secured and open configuration in which an openable liquid communication pathway between said first and said second aperture is opened;
The assembly of any preceding claim, wherein the gas communication pathway is configured to inhibit the passage of a liquid therethrough.
The assembly according to any preceding claim, wherein the assembly is configured to close both the liquid communication pathway and the gas communication pathway responsive to movement away from the secured position.
The assembly according to any of the preceding claims, wherein, in the open position, the assembly is operable to permit liquid to be transferred through the liquid communication pathway, and for a substantially equivalent volume of gas to be expelled through the gas communication pathway.
The assembly of any preceding claim, wherein the assembly is biased towards the closed position.
The assembly according to any preceding claim, comprising a first valve arrangement for opening and closing said liquid communications pathway and a second valve arrangement operatively coupled to said first valve arrangement to open and close said gas communications pathway responsive to said movement of said assembly to said secured and open configuration.
The assembly according to any preceding claim, comprising:
The as assembly according to any of the preceding claims, comprising a male member, and a female member configured for securely and removably receiving said male member.
The assembly according to any of the preceding claims, comprising a bayonet-type arrangement.
The assembly according to any of the preceding claims, comprising a magnetic-type arrangement.
The assembly according to any of the preceding claims comprising a screw-type arrangement.
The assembly according to any of the preceding claims, comprising a slide-type arrangement.
The assembly according to any of the preceding claims comprising a friction-fit-type arrangement.
The assembly according to any of the preceding claims, comprising a speed-fit type arrangement.
A reservoir portion for controlling the ingress of liquid into the reservoir portion and the egress of gas from the reservoir portion, the reservoir portion comprising an first openable aperture for providing a liquid pathway for the ingress of a liquid into the reservoir portion and second openable aperture for providing a gas pathway for the egress of gas from the reservoir portion, wherein the liquid pathway and the gas pathway are physically separate from each other within the reservoir portion
A dispenser for dispensing a liquid, said dispenser configured to cooperate with the assembly of any preceding claim to dispense liquid through said assembly.
A reservoir for receiving and storing liquid, said reservoir configured to cooperate with the assembly of any preceding claim to receive liquid through said assembly.
An assembly for transferring liquid between a dispenser and a reservoir substantially as hereinbefore described and with reference to FIGS. 35 to 37 of the drawings.
A system for transferring liquid between a dispenser and a reservoir substantially as hereinbefore described and with reference to FIGS. 35 to 37 of the drawings.
