Method and apparatus for beverage extraction with improved gas cylinder access

摘要

Devices and methods for extracting a beverage from a container, such as a wine bottle. Beverage can be extracted from a container by inserting a needle through a container closure, such as a cork, delivering pressurized gas into the container via the needle, and dispensing beverage from the container via the needle. A pressure regulator may control a pressure of gas introduced into the container, and a lance used to pierce a pressurized gas cylinder may include a leading face arranged to reliably pierce a cylinder closure. The regulator may include valve features to reduce valve chatter or hammering and provide a more reliable pressure seal.

主权项

1. A piercing lance for piercing pressurized gas cylinders, comprising:
a body having a front piercing end, a rear end opposite the front piercing end, and a fluid passageway extending between the front piercing end and the rear end, the front piercing end including a tapered portion having an opening at a distal end of the tapered portion and a longitudinal axis, the tapered portion having a first surface partially defining the opening at the distal end that is arranged in a plane perpendicular to the longitudinal axis and a second surface partially defining the opening at the distal end that is arranged in a plane transverse and not perpendicular to the longitudinal axis.
