发明名称 Plastic bag
摘要 A plastic bag (10) having integral tying means eliminating the need for auxiliary fastening means is disclosed. The walls of the bag are perforated or cut in a generally continuous arc-like configuration adjacent the opening in the bag so as to form fastening ends (16) on the corners of the bag (10). Diagonally opposite fastening ends (16) are joined and tied forming adjacent knots (26) which can be used as a carrying handle (28) for same. The walls of the bag (10) adjacent the bottom thereof are joined by a generally continuous arc-like heat sealed seam causing the bottom of the bag (10) to assume a generally rounded configuration when filled resulting in an evenly distributed load over the seam.
