Abstract
Abstract For enveloping upright elements such as posts of various crosssectional configurations at ground level so as to inhibit the growth of vegetation, a collar is formed of flexible, waterresistant sheet material and a main opening is formed therein from which a slit extends to the outer edge of the sheet of material, the slit being for the purpose of facilitating envelopment of a post and the like at ground level. A flange is formed integrally with the sheet and is disposed about the opening formed therein and the opening and flange are configured so as to envelop closely the post or other similar element.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
160 words
A ground collar for enveloping at ground level an inanimate upright element whose periphery at ground level is of fixed and unchanging size and of predetermined configuration, said collar comprising a unitary cover sheet of flexible water resistant material, an opening formed in said sheet and being of similar configuration and size to the periphery of said element at ground level, a slit formed in said sheet and extending from its outer edge inwardly to the edge of said opening to facilitate envelopment of said element by said sheet, a cover flap disposed in overlying relation with respect to said slit, and an upwardly extending flange formed about the periphery of said opening and disposed in generally normal relation to said sheet and adapted to completely enclose and snugly engage the upright element about its entire periphery, said flange being severed along a generally vertical line the lower extremity of which coincides substantially with the inner end of said slit.
Claim 2
Dependent Claim
160 words
A ground collar for enveloping at ground level an inanimate upright element whose periphery at ground level is of fixed and unchanging size and of predetermined configuration, said collar comprising a unitary cover sheet of flexible water resistant material, an opening formed in said sheet and being of similar configuration and size to the periphery of said element at ground level, a slit formed in said sheet and extending from its outer edge inwardly to the edge of said opening to facilitate envelopment of said element by said sheet, a cover flap disposed in overlying relation with respect to said slit, and an upwardly extending flange formed about the periphery of said opening and disposed in generally normal relation to said sheet and adapted to completely enclose and snugly engage the upright element about its entire periphery, said flange being severed along a generally vertical line the lower extremity of which coincides substantially with the inner end of said slit.
Claim 3
Dependent Claim
44 words
A collar according to claim 1 wherein adhesive tape is secured to at least a part of the exterior surface of said flange and the adjacent surface of the element about the entire peripheries thereof so as to form a growth preventing junction therebetween.
Claim 4
Dependent Claim
27 words
A collar according to claim 1 wherein the element is T-shaped in cross sectional configuration and wherein said opening and flange are of corresponding size and configuration.
Claim 5
Dependent Claim
28 words
A collar according to claim 1 wherein the element is channel shaped in cross sectional configuration and wherein said opening and flange are of corresponding size and configuration.
Claim 6
Dependent Claim
28 words
A collar according to claim 1 wherein said cover sheet is of elongated generally rectangular configuration and wherein said opening and flange are disposed near one end thereof.
