Abstract
A process for dense packing on a conventional pallet three-cubic-foot bags containing a lightweight, loose material that will flow within that bag, by a stacking pattern where a pair of bags are arranged alongside and offset from one another on the pallet to make up each stack layer, with successive layers rotated ninety degrees (90.degree.) from the layer below; applying, in turn, to each bag a downward force, as by a person moving his feet thereon, to evacuate air from that bag and to shift the contents to fill in gaps or openings in the layer below; and securing that stack to the pallet for transport; and a stack of three-cubic-foot bags containing a lightweight, loose material by a practice of the process of the invention.
Claims11
A process for high density stacking of three-cubic-foot bags containing a lightweight, loose material on a standard pallet where a layer consists of a pair or bags laid side by side to leave open areas therebetween and to the pallet sides consisting of
- positioning a standard pallet within an arrangement for laterally supporting bags as they are stacked on said pallet;
- positioning on that pallet, as a first layer, a pair of bags offset from and alongside one another leaving open areas therebetween with opposite bag corners aligning with opposite pallet corners;
- positioning on that pallet, as a second layer, a pair of bags offset from and alongside one another and rotated ninety degrees (90.degree.) from said first layer with opposite bag corners aligned with opposite pallet corners, portions of the bags of said second layer positioned over to fill in said open area between said bags and the pallet sides of said first layer;
- positioning on that pallet, as subsequent layers to a desired stack height, pairs of bags offset from and laid alongside one another and each pair rotated ninety degrees (90.degree.) from the layer below the opposite corners of the bags of each layer aligned with opposite pallet corners and filling in said open areas between said bags and the pallet sides of said layer below;
- applying vertical pressure on each said bag in turn to force air out from the bag interior and to cause the materials therein to flow into open areas in the layer of bags below said bag;
- and
- securing the stack of bags to the pallet.
A palletized stack of bags of lightweight, loose material where the individual bags are three-cubic-foot bags that have outside dimensions such that, when a pair of bags is laid alongside and offset to one another on the standard pallet there will be open areas between the bags and to the pallet sides comprising,
- a standard pallet;
- a stack of three-cubic-foot bags, each containing a lightweight, loose material, arranged on said pallet to a desired height, the bags stacked in pairs, with the bags in a first pair to form a first layer laid alongside and offset from one another on said pallet leaving open areas therebetween with opposite bag corners aligning with opposite pallet corners, with second and subsequent layers formed with a second pair and subsequent pairs of bags that are also laid alongside and offset from one another, each pair rotated ninety degrees (90.degree.) with respect to the pair below, with opposite bag corners of each pair aligned with opposite pallet corners and filling in said open areas in the layer below, each bag, in turn, having a vertical pressure applied thereon to evacuate air and to cause a flow of the loose materials within said bag to fill into said openings in the layer below;
- and
- means for securing the stack of bags to said pallet.
