  • Patent number: 5129512
    Abstract: A method of packaging goods within a packaging casing in which a substantially gas impermeable cup-shaped first casing part is provided having a depression and a peripheral lip. A web of gas permeable skin packaging material is placed over the depression and spaced from the bottom of the depression to form a space therebetween. A gas is then provided in the space. The web is sealed to the peripheral lip providing at least atmospheric pressure above to create a pressure differential above and below the web resulting in the web being stretched down inwardly of the depression. Goods are placed over the web, and an outer casing member is placed over the goods and the lip so that the permeable web is further stretched. The outer casing member is then sealed to the lip so that gas in the depression is allowed to permeate over an extended period of time through the web to the goods to enhance the keeping qualities of the goods.

  • Patent number: 5081819
    Abstract: A packaging machine and a method for continuous forming of filled packages from relatively unstretchable roll stock of crinkled heat sealable filter paper. A series of pouch forming drum sockets are provided in an outer surface of a revolving drum and the paper is trained on the drum over the sockets. Another mechanism is provided for slitting the sheet of the filter paper along its length creating a pair of side-by-side heat sealable filter paper strips before the paper reaches the drum. A driven endless flexible before the paper reaches the drum. A driven endless flexible belt is operatively engaged with the outer drum surface. A suction device is provided for drawing overlapped belt areas of the belt into the drum sockets along with the relatively unstretchable crinkled filter paper strips sandwiched between the overlapped belt area and the pouch forming drum sockets thereby forming side-by-side continuous strips of crinkled filter paper pockets.

  • Patent number: 5036643
    Abstract: An improved form, fill, seal and separate packaging machine for reclosable containers is accomplished by a plurality of stations disposed along a path of travel of a thermoplastic web including means to attach a pair of mated, resealable closure strips to the base web. The machine is intermittent in its operation, with movement of the web through the machine controlled so that the various steps of applying the closure strips, forming, filling, sealing and separating the reclosable containers are performed during periodic stops of the machine. The machine is further characterized by its use of two pairs of web belts to move the web through the machine. A first pair of web belts initially receive the folded web stock and partially form and completely fill the containers. The second pair of web belts overlap with the downstream end of the first pair of belts, but are disposed lower than the first belts.

  • Patent number: 5029432
    Abstract: Bags having a spout opening defined by a spout edge surface affixed within the bags are sealed with a spout closure membrane first by pressing the closure membrane against the spout edge surface with a cooled plate. A heating unit which includes a heating element, which has a surface which corresponds in size and shape with the spout edge surface, then is moved adjacent the cooled plate to heat a portion of the cooled plate for sealing the closure membrane to the spout edge surface. After heating the closure membrane for sealing the spout edge surface to the closure membrane, the heating element is moved away from the plate whereby the heated portion of the plate then cools and cools the seal. After the seal is cooled, the plate then is moved away from the sealed spout and bag.

  • Patent number: 5024317
    Abstract: An apparatus for closing lidded cartons has a turning station including a flightless horizontal conveyor, and a chain conveyor which extends along one side of the flightless conveyor and has light restraint members pivotally mounted on its links. The chain conveyor is moved in the same direction as the horizontal conveyor, but at a slower speed. Part way along the chain conveyor an upwardly directed air jet moves the restraint members individually but in succession to temporary raised positions in which they are available for engagement by a carton which is moving along the flightless conveyor in overlapping relation to the chain conveyor. A restraint member engaged by a carton in this way thereafter serves as a fulcrum about which the carton pivots through a substantial angle. Plough bars later complete the rotation of the carton through in total.

  • Patent number: 5020298
    Abstract: An improved packaging device designed for the filling of flexible, tubular casing and for the sealing of the casing in discrete lengths which may then be further processed or packaged. The device includes a mounting assembly having a floor mounted frame with a rotatable platform supported by the frame. Adjacent the frame and platform is a device for feeding product through a product horn into casing which is shirred on the horn. The platform includes a plurality of specially designed clippers arranged in a circular array. As filled casing is discharged from the feeding mechanism it is directed tangentially into the circular array of rotating clippers which are equally spaced from each other. The clippers sequentially operate to gather the casing, apply spaced, double clips to the casing, sever the connection between adjacent clips, and to then discharge the packaged link from the device.

  • Patent number: 5014492
    Abstract: The first object of the invention is a process for closing or sealing a flexible tube filled with a liquid, creamy or semi-pasty product (7), in which its skirt (2) is nipped below its open end so as to bring about a closure (10) allowing the escape of the air contained in the tube when the latter is transversely compressed and then after compression the closure (10) is transformed into a tight closure and the open end (17) of the tube is sealed. According to the invention, skirt (2) is nipped with elastically tightened parallel surfaces (10) and the skirt (2) is compressed to the right of the product contained (7), in such a way that the upper level of said product (7) remains below or at the lower limit of closure (10) and the end portion (17) of the tube (1) passing beyond said closure (10) is sealed, so as to avoid any pollution by the product deteriorating the seal. The second object of the invention is an apparatus for performing this process.

  • Patent number: 5012629
    Abstract: A method is disclosed for producing infusion coffee filter packs in which a first strip of filter paper is placed adjacent to a mold having a cylindrical mold pocket, and the strip of filter paper is caused, either mechanically or by a vacuum, to conform to the cylindrical mold pocket. The conforming step causes the surface area of the first strip of filter paper to stretch and increase by at least three percent relative to its area prior to the conforming step. A measured quantity of ground coffee is then deposited into the mold pocket over the filter paper conformed thereto. A second strip of filter paper is placed over the first strip of filter paper and the ground coffee in the mold pocket. The first and second strips of filter paper are then sealed together around the coffee filled mold pocket, as by a heat sealing press pressing and sealing the strips together. The filter paper is then trimmed as by die cutting to produce a half inch wide flange area extending around the mold pocket.

  • Patent number: 5009060
    Abstract: A vacuum packaging apparatus suitable for use in packing fluid foodstuffs or the like into bags. In a chamber are disposed a pair of support members having surfaces opposite relative to each other which are individually formed with suction holes. When a bag is fed between the pair of support members, vacuum is applied through the suction holes so that opposite surfaces of the bag are sucked into the opposite surfaces of the support members. Subsequently, the support members are moved away from each other, whereupon the mouth of the bag is opened. An object is fed into the mouth-opened bag for being vacuum packed therein. The resulting vacuum packaged product is supported in position between the pair of support members, being thereby flatly shaped.
