  • Publication number: 20080264000
    Abstract: A method and apparatus for loading and subsequently dispensing a plurality of flexible baglike containers. In one embodiment the baglike containers are configured in an unloaded, empty, mode to be in a substantially flat configuration. These flat items are stacked flat into a batching container and (such as a cardboard box) dispensed “off the bottom” of the stack by a container loading apparatus. The container loading apparatus grasps the flat items, pulls them from the bottom of the stack, and then loads them through a feed hole as known in the art. One of the inventions herein is the particular manner in which the flexible baglike containers are loaded into a stack within the batching container. Under this particular inventive manner, the bags are stacked in offset sub-batches. This provides improved stacking but still provides suitable dispensing characteristics. Another disclosed concept is the use of multiple boxes and an automated feed system for said boxes to reduce associated infeed labor.

  • Patent number: 7434375
    Abstract: A system for collecting a harvested product is provided. The system may include a continuously constructed flexible container for collecting the harvested product. For instance, the continuously constructed flexible container is a continuous sheet of flexible material such as plastic. A sealing device may be included within the system which is operationally coupled to the continuously constructed flexible container to allow the container to be sealed in discrete increments. Further, the system includes a traceability device operationally coupled to each of the discrete increments of the continuously flexible container to allow the harvested product included within each increment to be tracked. The use of the continuously constructed flexible container allows the harvested product to be collected continuously.

  • Publication number: 20080237239
    Abstract: A storage system comprising: an evacuable and reclosable bag comprising a wall made of a flexible material and a one-way valve attached to said wall of said bag; a container having walls made of a material less flexible than the flexible material; and an attachment device that attaches the bag to the container such that at least a portion of the bag resides within the container. To use this storage system, compressible articles are placed inside the evacuable bag. Then the bag is hermetically sealed and evacuated. During evacuation, the shape of the compressible articles inside the bag conform to the shape of the container interior volume. In one embodiment, when the bag with compressed articles is removed from the container, its shape facilitates stacking. In another embodiment, the storage bag with compressed articles remains inside the container.

  • Patent number: 7377087
    Abstract: A method of preserving foodstuffs in a heat-sealable plastic bag wherein three of the bag's four peripheral edges are permanently sealed together and the fourth of the edges comprises a temporary interlocking linear seal. After foodstuffs are placed into the interior of the bag, the linear seal is interlocked to form an inner chamber and to isolate those foodstuffs therein from the outside environment. The bag is then pierced to provide an opening through which the inner chamber of the bag is evacuated. Then, while the inner chamber is evacuated, heat is applied to seal around the opening or between the opening and the portion of the inner chamber containing the foodstuffs to isolate the foodstuffs within said evacuated inner chamber from the outer environment. The foodstuffs may be removed from the bag by opening the interlocking seal and the bags may be reused numerous times by re-interlocking the seal and repeating the evacuating and sealing process.

    Abstract: Method for providing a heat treated filled and closed can, including the consecutive steps of: filling a metal cup, closing the metal cup with a lid making a gas tight heat treatable can, heat treating the can, wherein measures are taken to achieve an under-pressure in the can after closing the cup and wherein the can is chosen that is either of a flexible type on the one hand or of a rigid type with increased strength provided with a seal on lid on the other hand. The measures comprise a step belonging to the group of steps consisting of: using a partly frozen filling; having the filling include constituents that interact after closing so as to lower the specific volume of the filling in the can; adding steam to the cup after filling and before closing; closing the cup under sub-atmospheric pressure; and partly evacuating the can after closing.

  • Patent number: 7178224
    Abstract: An apparatus is provided for making drainage elements in a vertical manner. In one embodiment, a vertically disposed hollow rotatable mandrel with a screw-threaded flight is used for guiding a length of perforated pipe and filling an annular space between the pipe and a cylinder of mesh material secured at one end to the pipe with aggregate. A hopper is used for directing the aggregate into the space between the mandrel and a cylindrical outlet of the hopper. A motor for driving the mandrel may be reversed at a slower speed than the forward speed to stop delivery of aggregate and to allow time for the upper end of the cylinder of mesh material to be severed and secured to the pipe to form a drainage element as well as to allow severance of the pipe. In another embodiment, the perforated pipe is driven through the hopper and the aggregate flows under gravity into the mesh sleeve.

  • Patent number: 7178315
    Abstract: A density controller is provided for a bagging machine designed for filling or packing material such as silage, compost or the like into an elongate flexible bag or container. The adjustable density controller comprises a drag member or strap with a selectively adjustable length that is positioned beneath the bag being filled and the ground. The weight of the material in the bag on the flexible member resists the forward movement of the bagging machine away from the closed end of the bag. The density of the material being packed or bagged is varied by the surface area of the flexible member that is positioned beneath the bag being filled.

  • Patent number: 7174924
    Abstract: A method for filling a container with a plurality of particles includes the step of filling a radially flexible container through a large diameter with a plurality of particles to a fill level. The method also includes the step of reducing the large diameter of the radially flexible container to a smaller fill diameter in vertical relationship to the fill level as the fill level rises during filling of the flexible container. The method also includes the step of varying the vertical relationship between the fill level and the smaller fill diameter in response to the density of the particles.

  • Patent number: 7155881
    Abstract: A valuable securing tote bag assembly and method includes a housing that has a bottom wall and a peripheral wall that is attached to and extends upwardly from the bottom wall. Each of the bottom and peripheral walls is flexible. The peripheral wall has an upper edge that forms a plurality of outer flaps. An inner flap is attached to an inner surface of the peripheral wall and divides the housing into an upper portion and a lower portion. A fastener is removably extendable through the outer flaps so that the outer flaps are secured together to define a closed position of the housing. The lower portion of the housing is filled with sand and valuables are positioned in the upper portion of the housing. The outer flaps are then secured together with the fastener.

  • Patent number: 7089716
    Abstract: Flexible ducting apparatus includes a packaging station and compression station, a support trough for supporting the ducting in the packaging station and compression station, and an actuating post which is arranged to engage a leading end of a length of flexible ducting to be packed and pull the length of ducting in a first direction through the packaging station into the compression station. The apparatus includes a control device to cause movement of a stop member into an operative position in the packaging station downstream of a trailing end of the length of ducting, the control device then being operative to cause the actuating post to execute a second stroke in the opposite direction to the first stroke so that the trailing end of the length of ducting is compressed against the stop member in the packaging station whereby packaging can be placed about the compressed length of ducting in the packaging station.
