Abstract
Abstract Containers such as laboratory glassware are stabilized in their upright resting position by means of a split torus; e.g., a high density rod, preferably of essentially circular cross-section, bent into a substantially, but incompletely closed loop.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
56 words
A stabilized container having a base area enlarged with respect to a portion of the container above the base area comprising in combination, said container and in cooperative relationship a heavy metal split torus surrounding and resting on said container at the base area of said container to stabilize said container in its upright resting position.
Claim 2
Dependent Claim
56 words
A stabilized container having a base area enlarged with respect to a portion of the container above the base area comprising in combination, said container and in cooperative relationship a heavy metal split torus surrounding and resting on said container at the base area of said container to stabilize said container in its upright resting position.
Claim 3
Dependent Claim
55 words
A container of the laboratory type having a base area enlarged with respect to a portion of the container above the base area combined and in cooperative relationship with a heavy metal split torus surrounding and resting on said container at the base area of said container to stabilize said container in its upright position.
Claim 4
Dependent Claim
55 words
A container of the laboratory type having a base area enlarged with respect to a portion of the container above the base area combined and in cooperative relationship with a heavy metal split torus surrounding and resting on said container at the base area of said container to stabilize said container in its upright position.
Claim 5
Dependent Claim
17 words
The container and split torus combination of claim 2 where the split torus is made of lead.
Claim 6
Dependent Claim
20 words
The container and split torus combination of claim 3 where the surface of the split torus is a soft material.
Claim 7
Dependent Claim
11 words
The combination of claim 4 where the soft material is polymeric.
Claim 8
Dependent Claim
15 words
The container and split torus of claim 5 where the polymeric material is polyvinyl chloride.
Claim 9
Dependent Claim
16 words
The container and split torus combination of claim 2 where the split torus is essentially circular.
Claim 10
Dependent Claim
15 words
The container and split torus combination of claim 2 where the split torus is multi-sided.
Claim 11
Dependent Claim
15 words
The container and split torus combination of claim 8 where the split torus is four-sided.
Claim 12
Dependent Claim
15 words
The container and split torus of claim 8 where the split torus is essentially triangular.
Claim 13
Dependent Claim
17 words
The container and split torus of claim 2 where the split torus is a truncated conical section.
Claim 14
Dependent Claim
46 words
The stabilized container of claim 1 where the split torus is essentially circular with a cross section of from about 0.3 to about 1 inch and where the ratio of outside diameter to inside diameter of said split torus is from about 1.25 to about 3.0.
