Abstract
Abstract A liquid stirrer for containerized liquids and particularly paint comprises a spanner bar having lips on each end thereof to engage between a container rim and lid, and a preferably semi-flexible blade structure depending from the spanner bar and extending into the liquid container such that reciprocating rotation of the paint can effects stirring of the liquid therein.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
183 words
A liquid stirrer for a container having a body portion with a bottom and a rim having an annular shoulder and a removable lid mountable on said rim, said stirrer comprising: a. a spanner bar removably extendable across a diameter of said annular shoulder and having a lip defined at each end thereof engageable between said annular shoulder and said lid such that said spanner is completely enclosed and firmly secured within a container when engaged by said lid and annular shoulder; b. a spatula depending from said spanner bar and comprising a pair of generally parallel blades to extend into said container and including a transverse blade joining the distal ends of said parallel blades; c. said spatula being semi-flexible to yield in use to swirling fluid in said container and extending into said container when said spanner bar is extended across said rim whereby said stirrer can be inserted into and completely enclosed within a container of liquid and captured by said lips between said rim and said lid to permit stirring of said liquid by reciprocal rotation of said can.
Claim 2
Dependent Claim
183 words
A liquid stirrer for a container having a body portion with a bottom and a rim having an annular shoulder and a removable lid mountable on said rim, said stirrer comprising: a. a spanner bar removably extendable across a diameter of said annular shoulder and having a lip defined at each end thereof engageable between said annular shoulder and said lid such that said spanner is completely enclosed and firmly secured within a container when engaged by said lid and annular shoulder; b. a spatula depending from said spanner bar and comprising a pair of generally parallel blades to extend into said container and including a transverse blade joining the distal ends of said parallel blades; c. said spatula being semi-flexible to yield in use to swirling fluid in said container and extending into said container when said spanner bar is extended across said rim whereby said stirrer can be inserted into and completely enclosed within a container of liquid and captured by said lips between said rim and said lid to permit stirring of said liquid by reciprocal rotation of said can.
Claim 3
Dependent Claim
29 words
Structure according to claim 1 wherein said annular shoulder is convex in radial cross-section and said lips are downwardly cupped to conform to and be retained by said shoulder.
Claim 4
Dependent Claim
30 words
Structure according to claim 2 wherein said parallel blades are each provided with a longitudinal reinforcing rib to encourage the uniform bending thereof from the ends adjacent the spanner bar.
