Abstract
Abstract A glass jug having a conventional cylindrical midportion is provided with a smaller diameter base, a larger radius at the bottom flaring portion, and an upper bulbous portion which extends above the lower portion of the handle, except in the immediate region of the handle. Although the new jug has the same volumetric capacity, it is easier to manufacture because of the large radius adjacent the base. Also it is lighter in weight, although it has the same wall thickness.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
138 words
In a glass jug having a cylindrical body portion, a central frustoconical neck at the upper end, and a ring handle formed integrally at one side of the neck, the improvement comprising, in combination: a circular base, a lower flaring portion joining the circumference of the base to the cylindrical body portion and having an outer surface which comprises a portion of a prolate spheroid, an upper bulbous portion joining the cylindrical body portion to the neck and extending symmetrically with respect to the handle but less than a full circle, said upper bulbous portion extending above the lower portion of the handle and having an outer toroidal surface of lesser radius than said lower flaring portion, and a convex portion joining said bulbous portion, cylindrical body portion and neck in the region of and below said handle.
Claim 2
Dependent Claim
138 words
In a glass jug having a cylindrical body portion, a central frustoconical neck at the upper end, and a ring handle formed integrally at one side of the neck, the improvement comprising, in combination: a circular base, a lower flaring portion joining the circumference of the base to the cylindrical body portion and having an outer surface which comprises a portion of a prolate spheroid, an upper bulbous portion joining the cylindrical body portion to the neck and extending symmetrically with respect to the handle but less than a full circle, said upper bulbous portion extending above the lower portion of the handle and having an outer toroidal surface of lesser radius than said lower flaring portion, and a convex portion joining said bulbous portion, cylindrical body portion and neck in the region of and below said handle.
Claim 3
Dependent Claim
157 words
In a glass jug having a cylindrical body portion, a central frustoconical neck at the upper end, and a ring handle formed integrally at one side of the neck, the improvement comprising, in combination: a circular base having a diameter substantially equal to three-fifths of the outside diameter of the cylindrical body portion, a lower flaring portion joining the circumference of the base to the cylindrical body portion and having an outer surface which approximates a portion of a sphere, an upper bulbous portion joining the cylindrical body portion to the neck and extending symmetrically with respect to the handle but less than a full circle, said upper bulbous portion extending above the level of the lower portion of the handle and having an outer toroidal surface of substantially lesser radius than said lower flaring portion, and a convex portion joining said bulbous portion, cylindrical body portion anD neck in the region of and below said handle.
