Patent number: 6668522Abstract: Method and device for packing bags filled with product in a box. The bags are made gas-permeable and after the bags have been filled with product the residual volume of gas therein is removed by drawing off the gases present in the bag by means of suction. This is achieved by conveying the bags over a belt on which vacuum is acting. Prior to this step the bags can be subjected to a vibratory treatment in order to optimise the position of the product in the bags.Type: GrantFiled: January 25, 2002Date of Patent: December 30, 2003Assignee: BluePrint Holding B.V.Inventor: Martin Prakken

Patent number: 6629404Abstract: A system for packaging articles, such as stacks of greeting cards or the like, includes an article handler, a group of film handlers, and a side sealer. Each of the film handlers includes a film roll holder, which is adapted to hold a roll of folded over film having a closed side and an open side. The film handler also includes a film holding arrangement adapted to hold open the film along an open side, and cross cutter including an end cutting and sealing blade arrangement positioned transverse to the length of the film and adapted to cut and seal an end of the film adjacent an end of an article. The article handler is positioned adjacent the film handlers.Type: GrantFiled: February 1, 2001Date of Patent: October 7, 2003Assignee: Hallmark Cards IncorporatedInventor: Robert E. McAnany

Patent number: 6619018Abstract: A bagging and packaging Machine has a substitute gas supply passage provided in a tube member 13 forming a part of a bag former 10 for forming a strip of packaging material into a bag. By securing a generally elongated plate 21 to a front inner side of the tube member 13 to thereby form the substitute gas supply passage 20 that extends in a direction parallel to the longitudinal sense of the packaging material from an upper portion down to a lower end portion of the tube member 13 and by rendering the cross-sectional area of the substitute gas supply passage 21 to be larger at a lower portion thereof than at an upper portion, the structure can be obtained in which a required quantity of substitute gas can be introduced into the bag-shaped packaging material at a moderate flow velocity.Type: GrantFiled: August 16, 2000Date of Patent: September 16, 2003Assignee: Ishida Co., Ltd.Inventor: Yukio Sasaki

Patent number: 6494023Abstract: A method and apparatus for inserting an oxygen scavenger into a modified atmosphere package for extending the shelf life of food, especially raw meats. A scavenger feeder feeds a chain of interconnected oxygen scavengers. A separator separates the oxygen scavenger located at an exposed end of the chain of interconnected oxygen scavengers from the chain of interconnected oxygen scavengers. An adhesive applicator applies adhesive to the oxygen scavenger which has been separated from the chain of interconnected oxygen scavengers. A conveyor conveys the separated oxygen scavenger to a position which is adjacent to a film layer which is used to form an outer package of the modified atmosphere package so that the oxygen scavenger is attached to a surface of the film layer by the adhesive. The film layer is subsequently formed into the outer package so that the oxygen scavenger that is attached to the film layer is contained within the outer package.Type: GrantFiled: August 10, 2001Date of Patent: December 17, 2002Assignee: Pactiv CorporationInventors: Gary R. DelDuca, Stephen L. Goulette, Darryl P. Hansen, Vinod K. Luthra

Patent number: 6473718Abstract: A method for determining bag size to adequately accommodate a food product filled into a ba y a form and fill machine, and subsequently determining the appropriate case pack configuration. The method efficiently and accurately determines a bag size that is large enough to accommodate the product that falls into the bag without interfering with the sealing process of the bag and while determining the appropriate amount of fill within the bag. The method uses various empirically determined relationships from historical bag sizing trials for a specific product and applies these relationships to a series of models in order to solve for a bag length. The method eliminates the need for costly and time-consuming bag sizing trials.Type: GrantFiled: November 4, 1999Date of Patent: October 29, 2002Assignee: Recct, Inc.Inventors: Patrick Joseph Bierschenk, Boderick Gerard Hall, Joseph Paul Sagel

Patent number: 6470652Abstract: A packaging device, particularly for foodstuffs or technical materials, comprising a bell-shaped vacuum chamber. A single-folded film can be placed in the vacuum chamber and the foodstuff can be inserted from the open longitudinal side of the film. Inside the bell-shaped vacuum chamber there is also provided a first transverse thermal bonding bar, which is laterally adjacent to a cutting blade, and a second thermal bonding bar, both bars being L-shaped. At least one nozzle for introducing gas is furthermore provided so as to face the longitudinal or transverse open side of the single-folded film.Type: GrantFiled: September 21, 2000Date of Patent: October 29, 2002Inventor: Andrea Piron

Publication number: 20010005974Abstract: A bagging and packaging machine for forming a bag from a strip of bag material and introducing an article into the bag includes a gas supply unit for supplying an inert gas into the bag to substitute for air contained in the bag and a gas supply control means for controlling supply of the inert gas by the gas supply means into the bag. The bagging and packaging machine is designed to allow the inert gas to be supplied under high pressure at a flow rate sufficient to increase the gas replacement rate in the bag when the machine is started, to be supplied under low pressure at a flow rate lower than the high pressure flow rate during a bagging and packaging operation subsequent to the start of the machine.Type: ApplicationFiled: December 27, 2000Publication date: July 5, 2001Applicant: ISHIDA CO., LTD.Inventors: Masashi Kondo, Ryoichi Sato

Patent number: 6253531Abstract: A platen machine for filling and sealing packages is provided having an upper platen and a lower platen journalled and independently moveable on a common alignment shaft to provide a close tolerance sealing mechanism with an independently operated heat seal element. The novel platen machine relocates clamping forces from the support frame to the alignment shaft so that the common alignment shafts bears the clamping forces and the carrier merely relies upon the frame to support the weight of the machine and not clamping forces. The upper platen moves toward the lower platen and the lower platen moves toward the upper platen to clamp a package between the two platens before an independently operated heat seal element is activated to advance to the clamped package and provide a heating and sealing cycle independent of the clamping cycle. Optional filling, gassing and evacuation can be provided during the clamping of the package without involving the separate heating and sealing operation.Type: GrantFiled: June 14, 1999Date of Patent: July 3, 2001Inventor: Richard L.
