Abstract
Abstract An improved infusion and stirring device is disclosed comprising a handle member having a first and a second portion. A first and a second retaining element are respectively secured to the first and the second portion of the handle member to stir an infusion liquid upon movement of the handle member. The first and second retaining elements engage opposite sides of a porous bag containing an infusion solid, such as a tea bag. A latch interconnects the first and second portions of the handle member thereby encompassing the porous bag to retain the porous bag between the first and second retaining elements as the handle member is moved to stir the infusion liquid. The improved structure may be readily injection molded from a plastic material.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
145 words
An improved infusion and stirring device comprising in combination: a handle member having a first and a second portion; each of said handle member portions comprising a longitudinally extending beam having a substantially constant cross sectional area; a first and a second retaining element respectively secured to said first and second portions of said handle member for stirring an infusion liquid upon movement of said handle member; each of said first and second retaining elements comprising at least an arm extending perpendicularly relative to said longitudinally extending beam; a hinge interposed between said first and second portions of said handle member enabling said first and second retaining elements to engage opposed sides of a porous bag containing an infusion solid; and a latch interconnecting said first and second portions of said handle member for retaining the porous bag between said first and second retaining elements.
Claim 2
Dependent Claim
145 words
An improved infusion and stirring device comprising in combination: a handle member having a first and a second portion; each of said handle member portions comprising a longitudinally extending beam having a substantially constant cross sectional area; a first and a second retaining element respectively secured to said first and second portions of said handle member for stirring an infusion liquid upon movement of said handle member; each of said first and second retaining elements comprising at least an arm extending perpendicularly relative to said longitudinally extending beam; a hinge interposed between said first and second portions of said handle member enabling said first and second retaining elements to engage opposed sides of a porous bag containing an infusion solid; and a latch interconnecting said first and second portions of said handle member for retaining the porous bag between said first and second retaining elements.
Claim 3
Dependent Claim
26 words
A device as set forth in claim 1, wherein each of said arms includes a bend in the terminal end thereof for encompassing the porous bag.
Claim 4
Dependent Claim
36 words
A device as set forth in claim 1, wherein each of said first and second retaining elements comprises an annular ring extending from said handle member to contact only the peripheral region of the porous bag.
Claim 5
Dependent Claim
60 words
A device as set forth in claim 1, wherein said first and second handle member portions are disposed along a common line extending through said longitudinal beams; and said hinge means being disposed between said first and second retaining elements for locating said first retaining element adjacent to said second retaining element upon folding said handle member about said hinge.
Claim 6
Dependent Claim
65 words
A device as set forth in claim 1, wherein said latch comprises a projection in one of said first and second handle portions and an aperture for receiving said projection disposed in the other of said first and second handle portions; one of said projection and said aperture being a deformable plastic material enabling said projection to be forced into said aperture and retained therein.
Claim 7
Dependent Claim
145 words
An improved infusion and stirring device comprising in combination: a handle member having a first and a second portion; a first and a second retaining element respectively secured to said first and second portions of said handle member for stirring an infusion liquid upon movement of said handle member; said first and second retaining elements comprising a plurality of arcuate arms extending on opposed sides of said first and second handle member portions; said arcuate arms respectively secured to end bars for encompassing a porous bag; latch means interconnecting said first and second portions of said handle member for retaining the porous bag between said first and second retaining elements; said latch means comprising plural projections cooperating with plural apertures; and one of said projections and said apertures being a deformable plastic enabling said projection to be forced into said aperture and be retained therein.
Claim 8
Dependent Claim
145 words
An improved infusion and stirring device comprising in combination: a handle member having a first and a second portion; a first and a second retaining element respectively secured to said first and second portions of said handle member for stirring an infusion liquid upon movement of said handle member; said first and second retaining elements comprising a plurality of arcuate arms extending on opposed sides of said first and second handle member portions; said arcuate arms respectively secured to end bars for encompassing a porous bag; latch means interconnecting said first and second portions of said handle member for retaining the porous bag between said first and second retaining elements; said latch means comprising plural projections cooperating with plural apertures; and one of said projections and said apertures being a deformable plastic enabling said projection to be forced into said aperture and be retained therein.
