The solution is then capped with a sterile inert gas such as nitrogen as a propellant. The aerosol container is then placed in a pouch and sealed about its periphery. The sealed pouch is then sterilized by gamma radiation. Sterile wipes can also be included in the sterile pouch if desired so that they will be readily available to wipe foreign matter from instruments, masks, glasses and the like, prior to applying the defogging agent. In the operating room, the sterile pouch is opened and discarded and the sterile defogging agent is sprayed on sterile instruments, masks, glasses and other articles to prevent condensation from forming on surfaces due to temperature differential.

  • Patent number: 5505039
    Abstract: A pressurizable package for a substance to be dispensed is formed by inserting a flexible liner into a pressurizable container and holding the closure of the container away from the mouth so that the space between the liner and the container can be pressurized with a gas. The closure is then sealed to the container to seal the space and maintain the pressure of gas around the liner which is evacuated to further collapse the liner, by applying a suction to a valve on the closure communicating with the interior of the liner. The liner is then filled through the valve with the substance to further pressurize the gas in the surrounding space.

  • Patent number: 5305582
    Abstract: A method is provided for the two-stage pressurizing of a product in which a propellant gas may be immediately generated for use as a high-pressure propellant after the sealing of the container. A first reactant and the flowable or sprayable product which is desired to be dispensed is placed into the container until the container is substantially full. The container is then sealed. A second reactant, which may be dissolved in a further amount of product, is introduced in liquid form into the sealed container through a dispensing valve, another valve, or a sealable plug. The first and second reactants react to generate the propellant, which is then contained or dissolved with the product in the container until needed. As product is expelled, the propellant evolves out of the product to exert expulsive pressure. Thus, the invention involves the process of charging during the filling of product and allows the product to be dispensed promptly and continuously thereafter.

  • Patent number: 5247777
    Abstract: In the "undercap" method of, and closure cap crimper-propellant fill head apparatus for, introducing a charge of volatile propellant in its liquid state into an aerosol container containing product to be dispensed, a significant residual amount of the propellant charge remains in the crimper-propellant fill head bell after the closure cap has been secured in place to seal the container. Not all crimper-propellant head machines are equipped with systems for reclaiming residual propellant, and even when so equipped, it is not always practical to reclaim residual propellant since certain products to be dispensed will foul the reclamation equipment. According to this invention a compressed purge gas is injected into the crimper-propellant fill head bell to purge a substantial portion of the residual propellant into the container before it is sealed by crimping its closure cap on the container mouth.

  • Patent number: 5244117
    Abstract: Carbonated and non-carbonated beverages are selectively dispensed under the driving force of a one time charge of pressurized inert gas inserted into the headspace of the beverage container at the time of bottling/canning. The gas, preferably nitrogen, is inert to the beverage liquid and is pressurized sufficiently to permit dispensing of all of the liquid from the container via a siphon tube. A cap valve seals the container and includes an elastomeric check valve preventing escape of gas while permitting the siphon tube to be inserted into the container. A throttling and diffusing valve controls outflow from the siphon tube to ambient and prevents fracturing of gas from the beverage liquid to minimize foaming/frothing.

  • Patent number: 5234137
    Abstract: A disc for mounting a valve onto a spray can which is capable of engaging a standard-sized protective cap such that the cap fills all the space between the disc and the top of the spray can regardless of variations in the thickness of the disc or the seal. The disc has a central body portion and an annular groove disposed at the periphery of the central body portion. The bead of the spray can sits within the annular groove. A seal is positioned between the annular groove and the bead. A spacer is positioned in the annular groove such that the spacial relationship between the bead and the annular groove is predetermined, i.e., the distance between the annular groove and the top of the can is a predetermined distance. Consequently, a standard-sized protective cap can be used for spray cans in which the seal thickness and disc thickness vary, wherein the cap fits snugly on the disc and fills the entire space between the disc and the top of the can.
