Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
130 words
A container structure for use with a disposable liner bag, comprising: a main body portion including an upstanding wall and a base; a rim extending from said upstanding wall and defining an opening at the upper end of said container structure, said rim terminating in a downwardly directed peripheral edge portion; and projections extending downwardly from said rim and being substantially coplanar with said peripheral edge portion so as to leave unobstructed space on the underneath side of said rim, between said wall and each projection, said projections positioned to deformably engage the bag causing the material to be forced to an engagement position with the underneath side of said rim as other bag material presses against the upper side of said rim creating a locking action about said rim.
Claim 2
Dependent Claim
130 words
A container structure for use with a disposable liner bag, comprising: a main body portion including an upstanding wall and a base; a rim extending from said upstanding wall and defining an opening at the upper end of said container structure, said rim terminating in a downwardly directed peripheral edge portion; and projections extending downwardly from said rim and being substantially coplanar with said peripheral edge portion so as to leave unobstructed space on the underneath side of said rim, between said wall and each projection, said projections positioned to deformably engage the bag causing the material to be forced to an engagement position with the underneath side of said rim as other bag material presses against the upper side of said rim creating a locking action about said rim.
Claim 3
Dependent Claim
16 words
The container of claim 1, wherein each said projection is triangular with an apex extending downwardly.
Claim 4
Dependent Claim
34 words
The container of claim 2, wherein each said projection depends from a recess in said rim portion such that the lower peripheral edges of said projections do not extend below the peripheral edge portion.
Claim 5
Dependent Claim
24 words
The container of claim 1, wherein each said projection depends from a recess in said rim portion and extends beyond the peripheral edge portion.
Claim 6
Dependent Claim
14 words
The container of claim 1, wherein said projections are removable fastened to said rim.
Claim 7
Dependent Claim
17 words
The container of claim 1, wherein said projections are provided in sets of two closely spaced projections.
Claim 8
Dependent Claim
65 words
The container of claim 1, wherein said projections are provided in sets of three and wherein a center projection is closely flanked on each lateral side by an outside projection, said center projection being substantially triangular in shape with its base near said upper edge portion, and said outside projections being shorter in length than said center projections and having flattened or rounded peripheral edges.
Claim 9
Dependent Claim
96 words
A rubbish container comprising: structure including a main body portion and an upper edge portion, said upper edge portion comprising a rim with a downwardly directed peripheral edge portion; and, a bag substantially covering the inner periphery of said main body portion and extending beyond said upper edge portion, said container further comprising projections extending from and being substantially coplanar with said peripheral edge portion and attached thereto with an unobstructed space between each projection and said main body portion for deformably engaging said bag thereby forming a resilient mount of said bag on said structure.
Claim 10
Dependent Claim
96 words
A rubbish container comprising: structure including a main body portion and an upper edge portion, said upper edge portion comprising a rim with a downwardly directed peripheral edge portion; and, a bag substantially covering the inner periphery of said main body portion and extending beyond said upper edge portion, said container further comprising projections extending from and being substantially coplanar with said peripheral edge portion and attached thereto with an unobstructed space between each projection and said main body portion for deformably engaging said bag thereby forming a resilient mount of said bag on said structure.
Claim 11
Dependent Claim
14 words
The rubbish container of claim 8, wherein said peripheral edge portion is downwardly directed.
Claim 12
Dependent Claim
16 words
The rubbish container of claim 9, wherein said projections are integral with said peripheral edge portion.
Claim 13
Dependent Claim
33 words
The rubbish container of claim 9, wherein said projections depend from recesses in said rim portion such that the lower peripheral edges of said projections do not extend below said peripheral edge portion.
Claim 14
Dependent Claim
25 words
The rubbish container of claim 9, wherein each said projection depends from a recess in said rim portion and extends below said peripheral edge portion.
Claim 15
Dependent Claim
17 words
The rubbish container of claim 8, wherein said projections are removably fastened to said upper edge portion.
Claim 16
Dependent Claim
18 words
The rubbish container of claim 8, wherein said projections are provided in sets of two closely spaced projections.
Claim 17
Dependent Claim
66 words
The rubbish container of claim 8, wherein said projections are provided in sets of three and wherein a center projection is closely flanked on each lateral side by an outside projection, said center projection being substantially triangular in shape with its base near said upper edge portion, and said outside projections being shorter in length than said center projection and having flattened or rounded peripheral edges.
Claim 18
Dependent Claim
97 words
A container structure for use with a disposable bag to be inserted within, comprising: a main body portion; an upper rim continuously extending outwardly and then downwardly from said main body portion; at least one projection extending downwardly from said upper rim, said projection being triangular in configuration with downwardly extending sloping sides to create an apex at the lowest point of said projection whereby a portion of the bag material upon engagement with said projection is forced to the inner side of said rim, as other bag material presses against the upper side of said rim.
Claim 19
Dependent Claim
97 words
A container structure for use with a disposable bag to be inserted within, comprising: a main body portion; an upper rim continuously extending outwardly and then downwardly from said main body portion; at least one projection extending downwardly from said upper rim, said projection being triangular in configuration with downwardly extending sloping sides to create an apex at the lowest point of said projection whereby a portion of the bag material upon engagement with said projection is forced to the inner side of said rim, as other bag material presses against the upper side of said rim.
Claim 20
Dependent Claim
37 words
The container structure of claim 16 wherein said at least one projection comprises a series of adjacent projections whereby inverse triangular slots are formed between said adjacent projections to gather, wedge and grip the forced bag material.
Claim 21
Dependent Claim
33 words
The container structure of claim 16 further comprising at least one flattened member positioned adjacent said projection and extending downwardly from said rim to facilitate gathering, wedging and gripping of the bag material.
