Devices and methods for engaging a gas cylinder with a gas dispenser, such as a beverage extractor, an inflation device, or other system that uses pressurized gas. A resilient element may be used to force a gas cylinder into engagement with a piercing element to pierce an outlet of the gas cylinder. The resilient element may deform elastically and/or plastically when applying force to the cylinder to pierce the outlet and sealingly engage the cylinder with a receiver. The resilient element may compensate for cylinders having different sizes and/or provid...

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; anda 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. 2. The device of claim 1, further comprising a rigid force transmitter between the resilient element and the cylinder that provides a contact area between the force transmitter and the resilient element. 3. The device of claim 2, wherein the holder includes a threaded portion arranged to engage with a threaded portion of the body, the threaded portion of the holder being located near a top of the holder, and the resilient element is located near a bottom of the holder. 4. The device of claim 3, wherein the holder has a cup shape with an opening at the top of the holder and an interior space, and wherein the resilient element is located in the interior space near the bottom of the holder and is arranged to contact the bottom of the gas cylinder. 5. The device of claim 1, wherein the holder is threadedly engaged to the body such that the holder is rotatable relative to the body to a stop which prevents further rotation of the holder relative to the body. 6. The device of claim 1, further comprising the gas cylinder. 7. The device of claim 6, wherein the resilient element is attached to the bottom of the gas cylinder. 8. The device of claim 1, wherein the resilient element is a piece of elastomeric material. 9. The device of claim 1, wherein the body includes a regulator to regulate a pressure of gas delivered to the gas dispensing outlet and a valve to control flow of gas from the regulator to the gas dispensing outlet. 10. The device of claim 9, further comprising a needle attached to the body and in fluid communication with the gas dispensing outlet, the needle having a lumen and arranged to be inserted through a cork of a wine bottle so as to deliver pressurized gas from the gas dispensing outlet to an interior of the bottle. 11. The device of claim 9, wherein the needle is arranged to conduct a flow of wine through the needle to a wine outlet of the body, the body including a valve arranged to control flow of wine from the needle to the wine outlet. 12. 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 receiver arranged to sealingly engage with the neck of the gas cylinder to receive pressurized gas from the gas outlet and provide the gas to a gas dispensing outlet;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 cylinder drive arranged to move the gas cylinder and the receiver toward each other so as to force the neck of the gas cylinder into engagement with the receiver; anda resilient element arranged to transmit force of the cylinder drive to the gas cylinder 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. 13. The device of claim 12, wherein the receiver is attached to a body having a threaded portion, and wherein the cylinder drive includes a threaded portion arranged to engage with the threaded portion of the body to move the resilient element and the gas cylinder toward the receiver. 14. The device of claim 13, wherein the cylinder drive includes a cylinder holder including the threaded portion of the cylinder drive and arranged to hold the gas cylinder, and wherein the resilient element is located on the cylinder holder to contact the bottom of the gas cylinder. 15. The device of claim 14, wherein the cylinder holder includes a cup with an interior space to hold the gas cylinder, the cup having a top with an opening through which the gas cylinder is inserted into the interior space, wherein the threaded portion of the cylinder drive is located near a top of the cup, and the resilient element is located near a bottom of the interior space. 16. The device of claim 12, further comprising the gas cylinder. 17. The device of claim 16, wherein the resilient element is attached to the bottom of the gas cylinder. 18. The device of claim 12, wherein the resilient element is a piece of elastomeric material. 19. The device of claim 12, wherein the cylinder drive includes a stop that prevents movement of the cylinder drive beyond a stop point relative to the receiver. 20. The device of claim 12, further comprising a rigid force transmitter between the resilient element and the cylinder that provides a contact area between the force transmitter and the resilient element. 21. A method of 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 method comprising: moving a resilient element toward a bottom of the gas cylinder so as to deform the resilient element both elastically and plastically and move the gas outlet of the gas cylinder into engagement with a piercing element to pierce the gas outlet;sealingly engaging the neck of the gas cylinder with a receiver that receives pressurized gas from the pierced gas outlet; anddispensing the pressurized gas from the cylinder at a gas dispensing outlet of a gas dispenser. 22. The method of claim 21, wherein the steps of moving and sealingly engaging comprise threading a holder holding the gas cylinder and the resilient element onto a body to which the receiver is attached.
