Abstract

A process of serially dispensing and opening a bag from a bundle of bags includes providing a bundle of bags having at least a leading bag and a plurality of trailing bags. Tabs at the top of the bags fasten to a support and sever under a first force. A fastening adjacent the top of the rear bag wall of a leading bag joins to the top of the front bag wall of a trailing bag, this fastening severing under a second force. Pulling on the front bag wall of the leading bag to sever the front support tab of the leading bag from the support; continued pulling on the front bag wall of the leading bag severs the rear support tab of the leading bag. The front support tab of the trailing bag from the support is also severed. The rear support tab of the leading bag pulls on the front support tab of the trailing bag to sever both the rear support tab of the leading bag and the front support tab of the trailing bag from the support. Further continuing pulling on the front bag wall of the leading bag causes severing of the first force of the front support tab of the trailing bag. Thereafter, the second force fastening the rear bag wall of the leading bag to the front bag wall of the trailing bag is exceeded. This second force causes separation of the leading bag from the trailing bag in a bag open disposition.

A process of serially dispensing and opening a bag from a bundle of bags lacking discrete tags for bag support comprising the steps of:

providing a bundle of bags having at least a leading bag and a plurality of trailing bags with each bag of the bundle of bags having;
a front bag wall having a top, a bottom, and two parallel side edges;
a rear bag wall having a top, a bottom, and two parallel side edges;
two bag sides, each bag side joining one of the side edges of the front bag wall to one of the side edges of the rear bag wall to form a closed continuum around the front bag wall and the rear bag wall;
a bottom joining the bottom of the front bag wall and the bottom of the rear bag wall to form a closed bottom to the closed continuum of the bag;
cutting the bundle of bags to define;
at least one front support handle fastened to the front bag wall;
at least one rear support handle fastened to the rear bag wall;
a top to the bag which can be opened to receive articles within the bag;
providing a bond adjacent the top of the rear bag wall of a leading bag joined to the top of the front bag wall of a trailing bag, the fastening releasing under a second force;
providing at least one support for the front support handle and the rear support handle;
threading the front support handle and the rear support handle to the bags in the bag bundle to the support;
pulling on the front bag wall of the leading bag to release the front support handle of the leading bag from the support;
continuing pulling on the front bag wall of the leading bag to release the rear support handle of the leading bag and the front support handle of the trailing bag from the support whereby the rear support handle of the leading bag pulls on the front support handle of the trailing bag to release both the rear support handle of the leading bag and the front support handle of the trailing bag from the support;
continuing pulling on the front bag wall of the leading bag whereby the force attaching the rear bag wall of the leading bag to the front bag wall of the trailing bag is exceeded to cause separation of the leading bag from the trailing bag in a bag open disposition.
