  • Patent number: 4817824
    Abstract: A collapsible and reusable container for liquid and granular materials which has a cage and a generally cubical bag of a flexible material which collapses when empty. The cage has a bottom which supports the filled bag and upstanding side walls surrounding the bag which can be collapsed when the bag is empty to overlie the bottom of the cage to provide a compact package for storage and shipment prior to refilling and reuse of the container.

  • Patent number: 4798572
    Abstract: A collapsible bag and method of making it from blanks of a flexible material which are cut from an elongate web substantially without wasting any material between adjacent blanks. Each blank has a circumferential continuous central portion and four substantially identical isosceles triangular portions at each end of the blank. Adjacent sides of adjacent triangular portions are connected together to provide, when the bag is expanded or filled, generally square ends which are interconnected by generally rectangular side walls. An access opening is provided in an end of the bag by terminating the connections of its triangular portions short of their apexes. Preferably, a spout is received in the access opening and connected to the triangular portions.

  • Patent number: 4781472
    Abstract: A large bulk bag with a complimentary liner therein, both of a flexible material, and constructed and arranged so that when empty they can be folded into a generally flat and compact configuration. At least two spaced apart connectors between the bag and liner prevent the liner from being drawn out of the bag by the discharge of its contents while permitting the liner to collapse upon itself without being substantially restrained from doing so by the bag.

  • Patent number: 4781473
    Abstract: A large bulk container is provided with a lift strap formed from a strip of flexible material for lifting the bulk container. The bulk container has connecting side panels and either a closed or open top and preferably a generally rectangular shape when filled. The strip forms a loop above the panels and has two ends connected in overlapping relationshp to adjacent side panels. A diagonal line of connection is provided between the two sides of the strap forming the loop and above the side panels to orient the lifting forces generally into one plane and in a generally vertical direction. The lift strap thereby prevents separation from the connected side panels and the spilling of the container contents upon lifting by the strap.

  • Patent number: 4596040
    Abstract: A large bulk bag formed from a tubular blank of woven fabric having inwardly folded gusset panels along opposite side edges. While in the flattened condition, the blank is sewn along predetermined stitch lines and severed at predetermined portions so that, when the stitched and severed blank is expanded, it forms a bag of rectangular cross section having a closable spout at one or both ends. If a liner is to be used in the bag, the liner is formed from a gussetted tubular blank and sealed and severed along lines corresponding to the stitch severing lines on the bag so that the flat liner can be inserted into the flattened bag with the gussetted portions of the bag and liner interfitting in interleaved relation and the spout on the liner extending through the spout on the bag.
