Abstract: An apparatus for discharging the contents of a sealed container, such as a test tube, includes an inlet path and a discharge path with a delivery tube in the discharge path. A predetermined clearance is provided between the exterior of the delivery tube and the interior of the discharge path, the clearance providing venting, or blow-by, such that temperature changes do not cause accidental discharge of the contents of the container, while still maintaining sufficient resistance to venting for permitting pressurizing the interior of the test tube for accurately controlling the discharge of the test tube contents.

Abstract: Self-pressurized container which comprises a liner/sleeve assembly containing a thin, flexible radially expandable convoluted plastic liner, about 0.010 to about 0.020 inch think, inside an essentially cylindrical elastomeric sleeve. The liner is generally cylindrical, open at one end and closed at the other end, and comprises an outwardly turned flange and an upper sidewall adjacent to the open end and a convoluted portion comprising longitudinally extending convolutions which extend from the upper sidewall towards the closed end. The liner is formed in the convoluted state, and has memory so that it returns to the convoluted state when unstressed. The outside diameter of the liner, measured between diametrically opposite peaks of the convolutions when the liner is unstressed, exceeds the inside diameter of the elastomeric sleeve when unstressed. Both liner and sleeve expand radially outwardly when the liner is filled under pressure with product to be dispensed.

Abstract: The object of this invention is to provide vessels for storing a gas to be used for automatically maintaining a predetermined pressure inside a container carrying a liquid, as it would be a beverage containing bottle. Two embodiments of such vessels are presented: One in shape of a capsule which can be dropped inside a beverage bottle, the other in the form of a cartridge which is attached at the bottom of a container, such as a beverage bottle. Both embodiments turn off gas flow when they sense a pressure equal or lower than atmospheric, or higher than a pressure of a predetermined value.

Abstract: A squeezable dispenser having a main flexible outer container closed off by a top having an opening therein and an inner collapsible flexible fluid containing bladder. A one-way flow valve is mounted in the top normally closing off the opening in the top to prevent the contents of the bladder from contamination from external sources. A vent in the top provides fluid communication between the interior of the container and the exterior thereof. A sealing member overlies the valve and normally closes off the same. The dispenser can be squeezed to dispense liquid in the bladder out through the valve.

Abstract: A container system for holding and dispensing an oil-gasoline mixture uses a transparent container bearing indicia showing the quantity of liquid in the container, and an oil-measuring cup mounted to the fill cap so as to extend into the container when the cap is on. The cup is also transparent and marked with indicia showing the quantity of oil, or the desired oil-gasoline ratio. With the cap removed, the cup is filled to the desired level and its contents dumped into the container. A dispensing hose extends from a dispensing opening on the container, through which the mixture is dispensed. A special venting system is provided which prevents pressurized product from being vented toward the face of the user, and employs a vent nozzle the atmospheric vent opening of which is blocked by placing the dispensing end of the hose thereon when the system is arranged for storage, and is opened by the user to direct the venting downwardly when the hose is removed to provide dispensing.
