Abstract: A system is provided for the delivery of a liquid anesthetic agent ti ab anesthetic vaporizer. The system includes a supply container having a spout defining an outlet through which the agent can be discharged. A reservoir is provided in the vaporizer for holding the agent, and a receiving station is provided on the vaporizer for receiving the container spout. The agent flows from the container through the spout by gravity into the reservoir. The container spout is located at the station to define the maximum liquid level of the agent in the vaporizer when gas flow into the container is blocked by the rising level of the liquid agent. In one embodiment, a frangible seal is provided in the container, an outlet valve is provided in the container, and an inlet valve is provided in the receiving station. The valves open automatically as the container is inserted into the receiving station of the vaporizer.

Abstract: A disposable, ready-to-use container such as a nursing container is provided which includes a protection compartment separating the nipple or other dispensing member from the infant formula or other stored substance until the time of use. The protection compartment is partially defined by and is separated from the storage compartment by a breakable line of securement extending across the interior of the container. When the line of securement is manually broken from the container-exterior, the stored infant formula is allowed to enter the now open protection compartment for open communication through the nipple. An enclosure chamber about the nipple may also be provided in combination with the protection compartment, to separate the nipple from the environment. Alternatively to the enclosure chamber, a nipple cover including two flexible tabs interposed and secured between the container sheet material and the nipple may be provided.

Abstract: A disposable, ready-to-use container such as a nursing container is provided which includes infant formula or other substance to be stored and a nipple or other, dispensing member which is segregated from the environment until use by means of an enclosure chamber. The enclosure chamber is formed by extending the container sheets or wall around the nipple. The enclosure chamber includes a manually breakable line of securement to access the enclosure chamber and the nipple.
