Abstract

An extension collar is provided for use with a pail having an opening and containing mixable building material. The collar includes an annular body with an upper edge, an opposite lower edge, and a sidewall connecting the edges. In addition, the body has a diameter that is complementary to, and insertable into the opening of the pail such that upon insertion into the pail, the collar adds to a height of the pail.

First claim

What is claimed is:

1. An extension collar for use with a pail having an opening and containing mixable building material, comprising:
an annular body with an upper edge, an opposite lower edge, and a sidewall connecting said edges;
a plurality of axially spaced ribs radially projecting from an exterior of said sidewall and located between said upper edge and said lower edge;
at least one handle mount on said sidewall being located between a lowermost one of said axially spaced ribs and a next adjacent one of said ribs;
an annular seal associated with said lower edge and below a lowermost rib of said plurality of axially spaced ribs for sealingly engaging the opening of the pail;
said body having a diameter being complementary to, and insertable into the opening of the pail such that upon insertion into the pail, said collar adds to a height of the pail.

2. The extension collar of claim 1 , wherein said body is dimensioned to add to the height of the pail in the range of 3-5 inches.

3. The extension collar of claim 1 , further including at least one clip on said sidewall for releasably clamping said collar to the pail by engaging said lowermost rib and a rim of the pail.

4. The extension collar of claim 1 , wherein said lower end is tapered to slidingly and releasably engage the opening of the pail, an angle of said taper being in the range of 5-30°.

5. The extension collar of claim 1 , further including a mount-formed as a generally “V”-shaped notch cut into and depending from said upper edge for receiving a powered mixer.

6. A combination pail containing mixable building material and an extension collar for selectively increasing a height of said pail, comprising:
a pail having an opening;
an extension collar including an annular body with an upper edge, an opposite lower edge, and a sidewall connecting said edges;
said body having a diameter being complementary to, and insertable into said opening of the pail such that upon insertion into said pail, said collar adds to a height of said pail in the range of 3-5 inches; and
a mount formed as a generally “V”-shaped notch cut into and depending from said upper edge for receiving a powered mixer.

7. The combination of claim 6 , further including an annular seal associated with said lower edge for sealing engaging said opening of said pail.

8. The combination of claim 6 , further including at least one clip on said sidewall for releasably clamping said collar to said pail by engaging said lowermost rib and a rim of the pail.

9. The combination of claim 6 , wherein said lower end is tapered to slidingly and releasably engage said opening of said pail.

10. An extension collar for use with a pail having an opening and containing mixable building material, comprising:
an annular body with an upper edge, an opposite lower edge, and a sidewall connecting said edges;
a plurality of axially spaced ribs located between said upper edge and said lower edge;
an annular seal associated with said lower edge and below a lowermost rib of said plurality of axially spaced ribs for sealingly engaging the opening of the pail;
said body having a diameter being complementary to, and insertable into the opening of the pail such that upon insertion into the pail, said collar adds to a height of the pail;
at least one handle mount on said sidewall being located between said lowermost rib and a next adjacent one of said ribs;

at least one clip on said sidewall for releasably clamping said collar to the pail by engaging said lowermost rib and a rim of the pail; and
a mount formed as a generally “V”-shaped notch cut into and depending from said upper edge for receiving a powered mixer.

11. The extension collar of claim 10 , wherein said lower end is tapered to slidingly and releasably engage the opening of the pail, an angle of said taper being in the range of 5-30°.
