Claim 1
Independent Claim
270 words
An insulated pitcher comprising a. a hollow outer body member having an open top and a substantially flat bottom, b. a hollow inner body member which is shaped and dimensioned to fit within said outer body member in spaced relation thereto, the space between said inner and outer body members constituting an air insulating chamber for retarding the flow of heat between said inner and outer body members, c. cover means for closing the uppermost end of said inner and outer body members, d. an upwardly extending bulge formed in the central portion of the bottom of said hollow outer body member, e. an upwardly extending bulge formed in the central portion of the bottom of said hollow inner body member, f. the upwardly extending bulges set forth in (d) and (e) being in essentially vertically aligned supporting relationship and having the same radius of curvature, but the bulge of the inner body member subtending a smaller arc length so as to provide the air space set forth above, g. said outer body member being flanged at its upper most end, and wherein said inner body member being flanged at its uppermost end, and wherein the flange of the inner body member rests upon the flange of the outer body membeR, thereby closing the top margin of said air insulating chamber between said inner and outer body members, h. said cover being shaped to slideably engage over and partially around the flanges in said inner and outer body members so that said cover will slide in a plane perpendicular to the height axis of said inner and outer body members.

Claim 3
Dependent Claim
29 words
An insulated pitcher as defined in claim 1 wherein said cover is positionable to permit the withdrawal and replacement of the inner body member within said outer body member.
Claim 4
Dependent Claim
44 words
An insulated pitcher as defined in claim 1 wherein a handle is attached to the upper end of said outer body member, and wherein a thumb-engaging projection is formed in said cover member adjacent to said handle for opening and closing said cover member.
Claim 5
Dependent Claim
