Abstract: An apparatus for providing a container with a controlled environment utilizes a first flow system for applying a first source of environment to the interior of the container, a second flow system for applying a second source of environment to the interior of the container, and means for controlling application of the individual sources of environment such that the first and second sources of environment are applied simultaneously for at least some period of time. The apparatus is useful, for example, in food packaging applications whereby oxygen is removed from the food containers and replaced with a substantially inert environment prior to sealing the containers. In a preferred embodiment, a rotary drum-type apparatus is employed for exposing containers in a continuous sequence to the individual sources of controlled environment.

Abstract: A supply of a propellant gas is maintained at substantially uniform temperature and pressure. Uniform predetermined increments of the propellant gas are withdrawn in rapid succession and rapidly introduced into aerosol containers in which product to be dispensed has already been introduced. Such containers are subjected to ultrasonic frequency agitation during the introduction of the propellant thereby enhancing the speed of introduction. The propellant may be introduced into a container either by the "through-the-valve" method or by the "under-the-cap" method at conventional speeds using known commercial equipment.

Abstract: A cylinder (1) having a plunger tube (3) contains a mass of supercritical CO.sub.2 containing 7 to 8% dissolved hydrogen, surmounted by a gaseous sky constituted by hydrogen under a pressure higher than about 120 bars. Supercritical CO.sub.2 containing several percent of dissolved hydrogen can thus be obtained by merely opening the valve (5) of the cylinder. Used in the cosmetic industry.

Abstract: The plant comprises a conveyor (1) above which are disposed a device (3) for injecting liquefied gas into the containers and, on the downstream side of the device relative to the direction of travel of the conveyor, a device (4) for closing the containers, and a tunnel (5) for protecting the containers against the surrounding air and extending between the injecting device (3) and the closing device (4). Application in the packing of non-gaseous beverages and organic products in cans or bottles.

Abstract: A paper container filling a liquid content which comprises an upper air gap formed therein for sealing solely carbon dioxide or nitrogen gas and carbon dioxide. Thus, a recess is produced on the paper container by utilizing a small pressure reduction in the container generated as a result of carbon dioxide dissolved in the liquid content, and the recess is used as a criterion of deciding the presence of gas substitution, presence of pinhole of the container and the propriety of sealing of the container only by the recess. This container can be fully inspected by the naked eye. Further, a method of filling gas and apparatus for filling the gas in a paper container formed of a synthetic resin layer of aluminum foil or polyethylene mainly with paper by eliminating the abovementioned disadvantages and performing gas substitution merely by adding a simple unit on a filling machine, thereby holding taste, odor and nutrient components of the container contents for 4 or longer months.

Abstract: A beverage container pressurizer and more particularly to a screw threaded cap that replaces the screw threaded cap normally provided on large beverage containers and a manually operated reciprocating piston-type pump sealingly and releaseably connected with the screw threaded cap for pressurizing the beverage container to keep the carbonation suspended in a liquid state for sustaining the quality of a carbonated beverage for an extended life before "going flat". The replacement cap includes a valve assembly which permits entry of pressurized air from the pump but prevents egress of pressurized air from the container when the pump is removed. This arrangement enables a single pump to pressurize a number of beverage containers since the pump is separable from the replacement screw threaded cap which remains with the beverage container until all of the beverage has been consumed.

Abstract: A gassing apparatus for breaking bubbles at the surface of a newly filled bubbling product (beer) and thereafter removing air from the head space above the surface of the product. The gassing apparatus includes a new bubble breaker which provides for the breaking of the bubbles at lower than customary gas pressure followed by a gassing rail which is of sufficient length and gassing apertures to permit full air removal notwithstanding variations in head space. Preferably the bubble breakers are used in pairs with the gas in the second bubble breaker being at a pressure less than that in the first.

Into the check-valve assembly base is inserted a check valve assembly. The cap body has an aperture therein so as to be fluidly connected to the base when a compressed air nipple from a hose is inserted into the check-valve assembly. The compressed air flows through the base, past a gasket in the body having a slit therein for air passage and through the body to pressurize a fuel reservoir.

Abstract: A beverage carbonating apparatus for consumer use comprises a stand supporting a gas bottle and a nozzle, for insertion into the neck of a container holding the beverage to be carbonated, the nozzle being pivoted to the stand for movement about a horizontal axis between a first, inclined position where the container nozzle may be inserted into or removed from the container and a second, vertical position where carbonation occurs.

Abstract: A system and apparatus for the production of sparkling wine or other similar beverages by applying carbon dioxide to wine already bottled. Specifically a new and improved high pressure cap-type enclosure for the bottle permits the carbon dioxide to be applied through the cap with an applicator in the nature of a hypodermic needle.Upon removal of the applicator the cap self-seals itself at a high pressure and retains and holds for an indefinite time the carbon dioxide. An exact pressure of carbon dioxide is applied to the bottled wine in an amount that closely approximates the pressures of champagne. The sparkling wine may thereafter be aged without deterioration of the cap and hence without loss of pressure.

Abstract: A container filling apparatus includes a system for flushing air from a container during the filling of the container with a liquid such as a carbonated beverage. The filling apparatus includes a chamber having a filling valve at the lower end thereof which chamber is adapted to be filled with the beverage and lowered into the container before release of the beverage through the filling valve. A gas passage is associated with the chamber and is controlled so as to direct a volume of inert gas into the container prior to the opening of the filling valve to purge the air from within the container. During the actual filling of the container with the beverage, the gas passage is blocked; however, just prior to the termination of the filling cycle, the gas passage is opened to create a slight amount of foam at the surface of the beverage in the filled container and to place a layer of gas at the very top of the container to prevent the subsequent contamination of the beverage.
