1. A gas dispensing device for dispensing pressurized gas contained in a sealed gas cylinder having a neck with a top surface and a side surface, the top surface having a piercable gas outlet, the gas cylinder further having a bottom at an opposite end of the gas cylinder relative to the top surface, the device comprising:
a body having a gas dispensing outlet;
a receiver attached to the body and arranged to sealingly engage with the neck of the gas cylinder to receive pressurized gas from the gas outlet and provide the gas to the gas dispensing outlet of the body, the receiver including a piercing element arranged to pierce the gas outlet to release gas from the gas cylinder as the neck of the gas cylinder is forced into engagement with the receiver;
a holder arranged to receive the gas cylinder and arranged to engage with the body so as to force the neck of a received gas cylinder into engagement with the receiver; and
a resilient element arranged for positioning between the holder and a received gas cylinder to transmit force from the holder to the gas cylinder as the holder is engaged with the body to force the neck of the received gas cylinder into engagement with the receiver, the resilient element arranged to deform with force transmitted to the gas cylinder suitable to cause the piercing element to pierce the gas outlet,
wherein the resilient element is arranged to both elastically and plastically deform with force transmitted to the gas cylinder suitable to cause the piercing element to pierce the gas outlet.
