Abstract
A bag for waste disposal is disclosed. The bag has a tubular body with a top open end and a bottom closed end, the tubular body having a first section adjacent the top open end, and at least a second section adjacent to the bottom closed end. The first section has a greater stretchability than the second section. The tubular body in a flattened two-fold condition has a pair of side edges extending from a top edge to a bottom edge, the top edge delimiting the top open end, the bottom edge delimiting the bottom closed end.
Claims24
A bag comprising:
- a tubular body with a top open end and a bottom closed end,
- the tubular body having a first section adjacent the top open end, and at least a second section adjacent to the bottom closed end, the first section joined to the second section via a weld seam between the first section and the second section, the first section made of a material having stretchability characteristics different than that of a material of the second section, the first section having a greater stretchability than the second section, wherein the material of the first section is LLDPE and the material of the second section includes HDPE,
- the tubular body in a flattened two-fold condition having a pair of side edges extending from a top edge to a bottom edge, the top edge delimiting the top open end, the bottom edge delimiting the bottom closed end, the tubular body having an inner surface extending from the top edge and an opposite outer surface extending from the top edge, the inner surface facing an interior of the bag from the top edge and extending into the at least second section to face a waste receiving volume of the bag.
A bag roll comprising:
- a plurality of bags connected end to end and from a bottom edge of a bag of the plurality of bags in the bag roll to a top edge of a subsequent bag of the plurality of bags in the bag roll, the plurality of bags defined by:
- a tubular body with a top open end and a bottom closed end,
- the tubular body having a first section adjacent the top open end, and at least a second section adjacent to the bottom closed end, the first section joined to the second section via a weld seam between the first section and the second section, the first section having surface features only in the first section, the first section having a greater stretchability than the second section, and
- the tubular body in a flattened two-fold condition having a pair of side edges extending from the top edge to the bottom edge, the top edge delimiting the top open end, the bottom edge delimiting the bottom closed end.
1 more element
A bag comprising:
- a tubular body with a top open end and a bottom closed end,
- the tubular body having a first section adjacent the top open end, and at least a second section adjacent to the bottom closed end, the first section joined to the second section via a weld seam between the first section and the second section, the first section having corrugations defined in a material of the tubular body, the corrugations being only in the first section of the tubular body from the top open end, such that the first section has a greater stretchability than the second section, and
- the tubular body in a flattened two-fold condition having a pair of side edges extending from a top edge to a bottom edge, the top edge delimiting the top open end, the bottom edge delimiting the bottom closed end.
