Transportable Container for Bulk Goods and Method for Forming the Same

摘要

The packaging system forms a transportable container for bulk goods having stretch wrap that is spirally wrapped about a bottom support and bulk goods to define the transportable container. The stretch wrap contacts at least a portion of the bulk goods to squeeze and lock together the bulk goods. During filling, the bottom support of the transportable container lowers as the transportable container is formed to accommodate additional bulk goods. The stretch wrap is prestretched from a non-stretched state to a stretched state prior to disposing the wrap about a slip frame former in the stretched state. The wrap returns to its non-stretched state as it is disengaged from the slip frame former to squeeze and lock together the bulk goods disposed therein. The packaging system results in a transportable container that is optimally packed and shaped for the efficient filling of a truck for shipping.

主权项

1. A method of producing a transportable container for supporting bulk goods comprising the steps of:
positioning a non-rotating slip frame former adjacent a non-rotating bottom support, the slip frame former having at least one former wall to surround a portion of the transportable container and defining a frame opening for receiving bulk goods from a feed source; prestretching a stretch wrap being disposed from a rotary stretch wrapping device from a non-stretched state to a stretched state; rotating the rotary stretch wrapping device radially about the non-rotating slip frame former and bottom support to dispose the stretch wrap in the stretched state radially about the bottom support and a portion of the at least one former wall of the slip frame former to initially form the transportable container; filling the transportable container with bulk goods from the feed source through the frame opening to establish a fill level; vertically moving at least one of the slip frame former and the bottom support relative to other of the slip frame former and the bottom support in response to the fill level of the bulk goods in the transportable container to expose the filled portion of the transportable container therebetween as the transportable container is filled with bulk goods, the slip frame former being maintained in a position to surround the bulk goods in the transportable container; disengaging previously disposed portions of the stretch wrap from the slip frame former and allowing the stretch wrap to return to the non-stretched state to squeeze the filled portion of the transportable container and lock together the bulk goods disposed therein as the at least one of the slip frame former and the bottom support moves relative to the other of the slip frame former and the bottom support.
