A hamper comprising a bag formed to have a closed bottom end, an open top end and sidewall means extending therebetween, generally planar sheet means insertable into said bag to provide an upright support shell for said bag, said shell having an upper edge defining a shell upper opening plane, and said bag having reduction means for drawing said open end into a bag opening smaller than said shell upper opening yet large enough to allow insertion of desired items into said bag and lying generally in said shell upper opening plane.
Claim 2
Dependent Claim
92 words
A hamper comprising a bag formed to have a closed bottom end, an open top end and sidewall means extending therebetween, generally planar sheet means insertable into said bag to provide an upright support shell for said bag, said shell having an upper edge defining a shell upper opening plane, and said bag having reduction means for drawing said open end into a bag opening smaller than said shell upper opening yet large enough to allow insertion of desired items into said bag and lying generally in said shell upper opening plane.
Claim 3
Dependent Claim
43 words
The hamper of claim 1 in which said sidewall means has a length greater than the height of said shell to place said open top end above said shell upper opening plane before said reduction means is operated to reduce said open end.
Claim 4
Dependent Claim
57 words
The hamper of claim 1 in which said bottom end is generally circular and said bag is generally cylindrical, said shell comprising a generally rectangular plastic sheet rolled up to have overlapping ends and provide a generally cylindrical shell which is radially expandable from a relatively tightly rolled tubular shape outwardly to the diameter of said bag.
Claim 5
Dependent Claim
47 words
The invention of claim 1 in which said bag is a generally cylindrical duffel bag and said reduction means is a drawstring for closing the top end of said bag, said shell being a generally cylindrical shell having a height less than the length of said bag.
Claim 6
Dependent Claim
151 words
A laundry bag formed to have a generally circular bottom, a generally cylindrical sidewall, and an open top end, reduction means for reducing said open top end to a bag opening having a size variable from generally equal to the diameter of said bag down to a generally closed opening sufficient to retain the contents of said bag, and upright generally planar sheet means forming a cylindrical shell insertable into said bag to support the bag in an upright standing condition, said shell having an upper edge defining a plane, said shell and said bag being proportioned and designed such that, when said shell is inserted into said bag and said bag opening is reduced to less than the diameter of said shell yet large enough to allow insertion of desired items into said bag, said bag opening will lie generally in the plane of the upper edge of said shell.
Claim 7
Dependent Claim
151 words
A laundry bag formed to have a generally circular bottom, a generally cylindrical sidewall, and an open top end, reduction means for reducing said open top end to a bag opening having a size variable from generally equal to the diameter of said bag down to a generally closed opening sufficient to retain the contents of said bag, and upright generally planar sheet means forming a cylindrical shell insertable into said bag to support the bag in an upright standing condition, said shell having an upper edge defining a plane, said shell and said bag being proportioned and designed such that, when said shell is inserted into said bag and said bag opening is reduced to less than the diameter of said shell yet large enough to allow insertion of desired items into said bag, said bag opening will lie generally in the plane of the upper edge of said shell.
Claim 8
Dependent Claim
171 words
A laundry hamper comprising a reusable, durable laundry bag made in the form of a right cylindrical duffel bag with a drawstring closure of its top to be used over and over again, an upstanding, right cylindrical shell removably insertable concentrically into the bag to provide a removable support structure for the bag, said shell being formed from a sheet of plastic to have overlapping vertical end edges to be resiliently radially expandable as said drawstring is tightened and loosened, the radially outwardly movement of said shell being limited by the diameter of said bag, and said shell and bag being proportioned and sized such that, when said shell is inserted into the bag and they are placed upright, the drawstring opening can be tightened to provide a horizontal, generally circular top with a generally concentric access opening smaller than the diameter of said bag yet large enough to allow insertion of desired items into said bag and located generally in the plane defined by the upper edge of the Shell.
Claim 9
Dependent Claim
171 words
A laundry hamper comprising a reusable, durable laundry bag made in the form of a right cylindrical duffel bag with a drawstring closure of its top to be used over and over again, an upstanding, right cylindrical shell removably insertable concentrically into the bag to provide a removable support structure for the bag, said shell being formed from a sheet of plastic to have overlapping vertical end edges to be resiliently radially expandable as said drawstring is tightened and loosened, the radially outwardly movement of said shell being limited by the diameter of said bag, and said shell and bag being proportioned and sized such that, when said shell is inserted into the bag and they are placed upright, the drawstring opening can be tightened to provide a horizontal, generally circular top with a generally concentric access opening smaller than the diameter of said bag yet large enough to allow insertion of desired items into said bag and located generally in the plane defined by the upper edge of the Shell.
Claim 10
Dependent Claim
