Bag

摘要

The bag may include a draw tape that may be used to cinch closed the opening of the bag. The draw tape may include an elastic characteristic and may be smaller in size than the peripheral distance about the opening. The draw tape in its natural contracted state may partially constrict the opening. However, the draw tape may be stretched or expanded to enable a user to dilate the opening and fold the periphery of the opening over the rim of the canister. The draw tape may then recover or constrict to grip about the rim of the receptacle to hold the bag to the canister. In one embodiment, the bag may include a pattern proximate the bag opening to allow the bag opening to be stretched over the rim of the canister.

主权项

1. A thermoplastic bag comprising:
a first sidewall of pliable thermoplastic material; a second sidewall of pliable thermoplastic material overlaying and joined to the first sidewall along a first side edge, an opposite second side edge, and a bottom edge extending between the first and second side edges to provide an interior volume, the interior volume accessible by an opening provided by first and second top edges of the respective first and second sidewalls; a first draw tape in a first hem formed proximate the first top edge, the first draw tape attached to the bag at the first and second side edges and unattached to the bag between the first and second side edges such that the first draw tape can expand or stretch freely in the first hem, wherein the first draw tape comprises a pre-stretched region the pre-stretched region being pre-stretched by elongating the first draw tape in a range of about 5% to about 50% to provide an elastic characteristic to the pre-stretched region, wherein the pre-stretched region is devoid of a pattern of ribs that form the elastic characteristic; wherein the pre-stretched region with the elastic characteristic causes the first draw tape to partially constrict the opening of the bag when the first draw tape is in a relaxed state; wherein the pre-stretched region comprises a pattern of linearly arranged ribs formed therein that modify the elastic characteristic of the pre-stretched region.
