Abstract

A polymeric bag for storing items. The bag includes connector elements that can be connected together at different locations. The connection of the connector elements effectively reduces the volume of the bag so that it can more closely conform to the item stored in the back.

First claim

What is claimed is:

1 . A selectively sizeable polymeric bag comprising:
a first sheet of polymeric material having an interior surface and an exterior surface; a second sheet of polymeric material having an interior surface and an exterior surface, the second sheet of polymeric material being arranged so that the interior surface of the second sheet of polymeric material faces toward the interior surface of the first sheet of polymeric material, the second sheet of polymeric material being operatively connected to the first sheet of material to form a bag volume, the first and second sheets of material having an opening at one end for receiving items into the bag volume; a first closure element on an interior surface of the first sheet of polymeric material proximate the opening; a second closure element on an interior surface of the second sheet of polymeric material proximate the opening, the second closure element having a different configuration from the first closure element and being selectively mateable with the first closure element for closing the opening; a first connector element located on the exterior surface of the second sheet of polymeric material; second connector elements, at least one of the second connector elements being located on the exterior surface of the first sheet of polymeric material and at least one of the second connector elements being located on the exterior surface of the second sheet of polymeric material when the bag is configured to have a maximum volume, the first connector element being configured for selective connection to any one of the second connector elements, the second connector elements being arranged so that the bag volume changes upon connection of the first connector element to different ones of the second connector elements.

2 . The polymeric bag as set forth in claim 1 wherein the second connector elements are mounted on the exterior surface of the second sheet of polymeric material.

3 . The polymeric bag as set forth in claim 1 wherein the second connector elements are mounted on the exterior surface of the first sheet of polymeric material.

4 . The polymeric bag as set forth in claim 1 wherein a plurality of the second connector elements are mounted on both the exterior surface of the first sheet of polymeric material and the exterior surface of the second sheet of polymeric material.

5 . The polymeric bag as set forth in claim 1 wherein the second connector elements are spaced apart from each other along a path extending from the opening toward an end of the bag opposite the opening on the second sheet of polymeric material and thence from the opposite end of the bag to the opening on the first sheet of polymeric material.

6 . The polymeric bag as set forth in claim 1 wherein the first and second sheets of polymeric material have side edges joined together, the first connector element and each of the second connector elements extending from one side edge to the other side edge of the first and second sheets of polymeric material.

7 . The polymeric bag as set forth in claim 1 wherein the second sheet has an upper edge located at the opening in the bag, and the first connector element is located below the upper edge of the second sheet.

8 . The polymeric bag as set forth in claim 7 wherein the first connector element is one of a male connector element and a female connector element, and the second connector elements are each the other of the male connector element and the female connector element.

9 . A selectively sizable polymeric bag comprising:
a first sheet of polymeric material having an interior surface and an exterior surface; a second sheet of polymeric material having an interior surface and an exterior surface, the second sheet of polymeric material being arranged so that the interior surface of the second sheet of polymeric material faces toward the interior surface of the first sheet of polymeric material, the second sheet of polymeric material being operatively connected to the first sheet of material to form a bag volume, the first and second sheets of material having an opening at one end for receiving items into the bag volume; a first closure element on an interior surface of the first sheet of polymeric material proximate the opening; a second closure element on an interior surface of the second sheet of polymeric material proximate the opening, the second closure element having a different configuration from the first closure element and being selectively mateable with the first closure element for closing the opening; a first connector element located on the exterior surface of the second sheet of polymeric material; second connector elements located on the exterior surface of at least one of the first and second sheets of polymeric material, the first connector element being configured for selective connection to any one of the second connector elements, the second connector elements being arranged so that the bag volume changes upon connection of the first connector element to different ones of the second connector elements; the second connector elements being spaced apart from each other along a path extending from the opening toward an end of the bag opposite the opening on the second sheet of polymeric material and thence from the opposite end of the bag to the opening on the first sheet of polymeric material.

10 . A selectively sizable polymeric bag comprising:
a first sheet of polymeric material having an interior surface and an exterior surface; a second sheet of polymeric material having an interior surface and an exterior surface, the second sheet of polymeric material being arranged so that the interior surface of the second sheet of polymeric material faces toward the interior surface of the first sheet of polymeric material, the second sheet of polymeric material being operatively connected to the first sheet of material to form a bag volume, the first and second sheets of material having an opening at one end for receiving items into the bag volume; a first closure element on an interior surface of the first sheet of polymeric material proximate the opening; a second closure element on an interior surface of the second sheet of polymeric material proximate the opening, the second closure element having a different configuration from the first closure element and being selectively mateable with the first closure element for closing the opening; a first connector element located on the exterior surface of the second sheet of polymeric material; second connector elements located on the exterior surface of at least one of the first and second sheets of polymeric material, the first connector element being configured for selective connection to any one of the second connector elements, the second connector elements being arranged so that the bag volume changes upon connection of the first connector element to different ones of the second connector elements; the first and second sheets of polymeric material have side edges joined together, the first connector element and each of the second connector elements extending from one side edge to the other side edge of the first and second sheets of polymeric material.
