The device may include a bottle closure, which may be attached to an anesthetic bottle until it is time for the anesthetic to be transferred to a vaporizer. A membrane may be used to seal the opening in order to prevent the anesthetic from leaving the reservoir until it is desired to fill the vaporizer. In order to protect the membrane a cap and a cap support may be placed on the reservoir so as to cover the membrane. The container may further include a connecting surface on the cap support or the reservoir, the connecting surface being connectable to a vaporizer. The system includes a vaporizer having a side slotted tube needle that is able to pierce the membrane and through which the liquid anesthetic agent and/or vapor may pass from the reservoir to the vaporizer. A method for transferring a liquid anesthetic from a container to a vaporizer. The method includes connecting a container which holds a liquid anesthetic to a vaporizer, and piercing a membrane of the container with a slotted needle of the vaporizer. ## Claims ### Claim 1 A container for supplying a liquid anesthetic to a vaporizer, the container comprising: a reservoir adapted for holding the liquid anesthetic; a membrane which covers an open end of the reservoir; a cap support connected to the reservoir; and a cap removably connected to the cap support. ### Claim 2 (depends on 1) The container of claim 1, further comprising a connecting surface configured for connection to the vaporizer. ### Claim 3 (depends on 2) The container of claim 2, wherein the connecting surface is defined by one of the following: the cap support; and the reservoir. ### Claim 4 (depends on 2) The container of claim 2, wherein the connecting surface defines at least one of the following: an internal thread; an external thread; and a male bayonet extension. ### Claim 5 (depends on 1) The container of claim 1, further comprising a crimp ring which surrounds the cap support. ### Claim 6 An anesthetic delivery system comprising: a container for supplying a liquid anesthetic, the container comprising: a reservoir adapted for holding the liquid anesthetic; a membrane which covers an open end of the reservoir; a cap support connected to the reservoir; and a cap removably connected to the cap support; and a vaporizer configured to receive the container, wherein the vaporizer comprises: a slotted tube, wherein the slotted tube is configured to pierce the membrane. ### Claim 7 (depends on 6) The system of claim 6, wherein the container further comprises a connecting surface configured for connection to the vaporizer. ### Claim 8 (depends on 7) The system of claim 7, wherein the connecting surface is defined by one of the following: the cap support; and the reservoir. ### Claim 9 (depends on 7) The system of claim 7, wherein the connecting surface defines at least one of the following: an internal thread; an external thread; and a male bayonet extension. ### Claim 10 (depends on 6) The system of claim 6, wherein the slotted tube defines at least one longitudinal slot through a wall of the tube. ### Claim 11 (depends on 6) The system of claim 6, further comprising an actuator connected to the slotted tube. ### Claim 12 (depends on 6) The system of claim 6, further comprising a flange connected to the slotted tube. ### Claim 13 (depends on 12) The system of claim 12, wherein the flange defines a plurality of through holes. ### Claim 14 A method for transferring a liquid anesthetic from a container to a vaporizer, the method comprising: connecting a container which holds a liquid anesthetic to a vaporizer; and piercing a membrane of the container with a slotted needle of the vaporizer. ### Claim 15 (depends on 14) The method of claim 14, wherein connecting the container comprises threadedly connecting the container to the vaporizer. ### Claim 16 (depends on 14) The method of claim 14, wherein connecting the container comprises engaging a male bayonet extension of the container with a slotted opening of the vaporizer. ### Claim 17 (depends on 14) The method of claim 14, wherein piercing the membrane comprises moving the slotted tube from a first position to a second position. ### Claim 18 (depends on 17) The method of claim 17, wherein moving the slotted tube comprises moving the slotted tube with an actuator of the vaporizer. ### Claim 19 (depends on 17) The method of claim 17, further comprising moving the slotted tube from the second position to the first position. ### Claim 20 (depends on 14) The method of claim 14, further comprising removing the slotted tube from contact with the membrane.
