Abstract

This invention is a novel plastic bag and method of making it with a handle that extends upward through a folded-back top compartment, and the end of a front of the bag has a pocket with a similar folded-over top edge of the back of the bag. The bags of this invention are made from a continuous sheet, preferably a roll of plastic web that has its opposite side edges folded inwardly along opposite edges of the web to make the folded edges at the front and back sides of the bag. The web is then folded along its longitudinal center region with a gusset that forms the bottom of each bag. The bags have surfaces that are welded together to join areas of the front and of the back where necessary to weld plastic areas together, and certain areas do not weld where the plastic sheet is coated on areas that prevent heat applied to the plastic from fusing together.

Dependent claims

The method of making a bag having front and rear sidewalls, the upper end of the rear sidewall being folded forward and downward at its upper end and having a slot through which a handle is inserted with a lower part of the handle longer than the slot and in contact with the inside of the fold beyond both ends of the slot to support the bag from the handle, the upper end of the rear sidewall of the bag being a continuation of the lower part of the rear sidewall, the upper part of the front sidewall being folded downward over the lower part of the front sidewall and temporarily held against the lower part of the front sidewall, and holding the folded upper end of the front panel with its folded top edge below the folded down panel of the folded rearward panel until the handle has been inserted into the folded rearward panel and pushed up through the slot in the fold at the top of the rearward side of the bag, then turning the upper end of the folded front panel by pulling a temporary connection free of the lower portion of the front wall of the bag after the handle has been inserted through the slot in the top of the folded portion of the rearward panel, and closing the bag by placing the folded front portion of the cover over the folded rearward portion of the bag with the handle extending through a slot in the top of the forward folded end of the bag to hold the bag closed.

The method of making a bag having front and rear sidewalls, the upper end of the rear sidewall being folded forward and downward at its upper end and having a slot through which a handle is inserted with a lower part of the handle longer than the slot and in contact with the inside of the fold beyond both ends of the slot to support the bag from the handle, the upper end of the rear sidewall of the bag being a continuation of the lower part of the rear sidewall, the upper part of the front sidewall being movably folded downward over the lower part of the front sidewall and against the lower part of the front sidewall, which method comprises holding the folded upper end of the front panel with its folded top edge below the folded down panel of the folded rearward panel until the handle has been inserted into the folded rearward panel and pushed up through the slot in the fold at the top of the rearward side of the bag, then turning the upper end of the folded front panel by unfolding the same upward from the lower portion of the front wall of the bag after the handle has been inserted through the slot in the top of the folded portion of the rearward panel, and closing the bag by placing the now-unfolded front portion of the cover over the folded rearward portion of the bag with the handle extending through a slot in the top of the now-unfolded folded end of the bag to hold the bag closed.
