Patent number: 5071667Abstract: Open-top cup-shaped containers which contain supplies of perishable foodstuffs are transported seriatim past a station where they receive jets of preserving gas which expels air from the unfilled portions of containers, and the containers are then sealed by application of metallic or plastic foils which are bonded or otherwise sealingly secured to washer-like rims surrounding the open tops of the containers. The foils can be partially applied ahead of the gas introducing station and are thereupon finally sealed in at least one second step, particularly in a chamber wherein the containers advance stepwise downstream of the gas introducing station and wherein the temperature and/or pressure is maintained at a preselected value to promote expulsion of air from the containers prior to the final sealing step.Type: GrantFiled: August 27, 1990Date of Patent: December 10, 1991Assignee: Lieder Maschinenbau GmbH & Co.

Patent number: 4885897Abstract: A method of making a hermetically sealed container is disclosed. In the method, a water vapor (40) is blown into a container body (1) that has been placed with a product such as solid foods or the like leaving a space portion (3). Immediately thereafter or immediately after an inert gas (51) has been blown into the container body, the container body is hermetically sealed. The container has a relatively low negative internal pressure which is controllable with a small range of variation. The water vapor (40) is generated by blowing a non-condensable gas such as air, nitrogen gas or the like at a constant flow rate into a water (13) which is controlled to a constant temperature. When the inert gas (51) is blown, only the surface and its vicinity of the product (4) is heated by blowing the water vapor (40).Type: GrantFiled: September 13, 1988Date of Patent: December 12, 1989Assignee: Toyo Seikan Kaisha, LimitedInventors: Toshio Gryouda, Shouichi Inaba, Michio Watanabe, Kanemichi Yamaguchi

Patent number: 4729208Abstract: A series of syringe bodies with their lower ends closed is filled with a solution of medicine to a predetermined level in the bodies. The syringe bodies are placed in a lyophilizer with the bodies arranged in a predetermined pattern. A plurality of plungers for the syringe bodies is arranged in a corresponding pattern and above the syringe bodies. After the medicine in the syringe bodies is lyophilized in the lyophilizer, a reduced pressure is created in the lyophilizer and the plungers are simultaneously moved into the syringe bodies to a predetermined level above the lyophilized medicine. The pressure within the lyophilizer is then increased to atmospheric and the assembled syringes are removed. Apparatus for implementing the process can include a lower rack having openings for retaining the syringe bodies in the predetermined pattern, and an upper rack seatable on the lower rack for retaining the piston portions of plungers in facing relation to, aligned with, and above the openings of the syringe bodies.Type: GrantFiled: June 25, 1987Date of Patent: March 8, 1988Inventors: Michel Galy, Alain Genet

Patent number: 4729204Abstract: At the upper side of the star wheel bottle feeder of a bottle capping machine, a chamber which encompasses the bottle neck is attached at each pocket in the periphery of the star wheel in which the bottle neck is registered as it is transported in a circular orbit. At the top side, the chamber has an opening for a reciprocating sealing element which revolves with the star wheel. The chamber has a circular internal bore and an opening on its radially outermost side that allows bottles to be passed through it and into a pocket on the star wheel. There is a nozzle slot at the radial inside of the chamber diametrically opposite from the outside gas exit opening. The gas input slot has an elbow connected to it and the elbow is connected to a gas distributor valve which is, in turn, connected to a source of carbon dioxide.Type: GrantFiled: April 25, 1986Date of Patent: March 8, 1988Assignee: Krones AG Hermann Kronseder MaschinenfabrikInventor: Wilhelm Weiss

Patent number: 4662154Abstract: A control system for providing a closed loop control circuit between a liquid nitrogen dispenser and apparatus for determining internal pressure within a closed can having liquid nitrogen applied thereto whereby the automatic controlling of the volume of liquid nitrogen dispensed into each can is effected. Control data from a pressure test unit is averaged and the average is compared to a preselected set point and converted into a pulse of a width varying in accordance with the average detected pressure of previously filled cans to control the time of dispensing and thus the volume of dispensed liquid nitrogen.Type: GrantFiled: October 12, 1984Date of Patent: May 5, 1987Assignee: Continental Can Company, Inc.Inventor: Gary G.

Patent number: 4658566Abstract: An improved method and apparatus for sealing jars and other containers within specialized environments, such as a vacuum, is provided. The containers are introduced into chambers of a rotary drum, and an outer enclosure for the drum is provided by means of a substantially flexible moving belt which conforms to the periphery of the drum and seals the chambers. A vacuum may then be introduced to the chamber to evacuate the interior of the container, and the lid of the container may then be secured to maintain the desired vacuum within the container. The flexible belt may move in synchrony with the rotation of the drum, eliminating relative motion between the outer enclosure and the drum and avoiding need for complex sliding seals. The device is quickly adaptable to sealing and closing numerous configurations and sizes of containers.Type: GrantFiled: January 13, 1986Date of Patent: April 21, 1987Inventor: John E. Sanfilippo

Patent number: 4655029Abstract: A method and apparatus for filling a bottle with an oxygen sensitive liquid such as beer in which the bottle is pre-evacuated, pressurized with pure CO.sub.2, over-filled with liquid at constant pressure and then brought back to the proper fill level by injecting pure CO.sub.2 and forcing the excess back into the gas pressurized liquid storage tank while the bottle is still coupled to the filling head. After uncoupling, the bottle is transported to under a closure cap applying device at which there are nozzles that project CO.sub.2 under the device and over and around the mouth of the bottle so the space even within the cap is purged of air. The CO.sub.2 used for purging is adequately free of air since it is taken from the storage tank to which CO.sub.2 is returned from the bottles as a result of filling liquid displacing the CO.sub.2 gas which is diluted only to the extent that pre-evacuation is not perfect.Type: GrantFiled: October 18, 1985Date of Patent: April 7, 1987Assignee: Krones AG Herman Kronseder MaschinenfabrikInventor: Wilhelm Weiss

Patent number: 4624099Abstract: A packaging machine wherein product-loaded cup-shaped receptacles are advanced with an indexing movement through a series of packaging stations. One station includes a fixed vacuum/gas chamber extending entirely over one set of receptacles. The receptacles are first evacuated through this fixed chamber, and thereafter gas is directed into the chamber to fill the receptacles. A fine wire-mesh screen is positioned between the chamber and the receptacles to constrain the air and gas flow to a vertical direction, to prevent disarrangement of the product during evacuation and gassing. A gas-curtain structure develops an enclosed region of gas above the receptacles during their movement out from under the fixed chamber over to the final sealing station. The sealing operation takes place in two successive steps within the sealing station.Type: GrantFiled: April 7, 1980Date of Patent: November 25, 1986Assignee: Mahaffy & Harder Engineering Co.Inventor: John R.
