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.

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.

' sum 1 BF 2 A 770E/V6 V5 GLASS JUG This invention relates to containers and more particularly to glass jugs. This invention will be described in connection with .a l-gallon glass jug, although it is to be understood that this is by way of illustration and not of limitation.
Glass jugs of conventional shape are symmetrical about a central axis except for the provision of a handle at one side of the neck of the jug. The neck is carried on a flaring portion which joins with a cylindrical central portion. At the lower end of the jug, the cylindrical central portion merges with a curved portion, which in turn merges with the circular bottom portion of the jug. In the conventional jug, the radius of the curved lower portion is relatively small, and the diameter of the circular base portion is relatively large, and this relationship has been the source of difficulty in the molding process. In accordance with this invention, the molding difficulties are alleviated by reducing the diameter of the base portion and markedly increasing the radius of the lower curved portion. This change taken alone, however, reduces the volumetric capacity of the glass jug. This loss in capacity, however, is compensated for by increasing the volumetric capacity of the upper curved portion of the jug, except in the region of the handle, so that without increasing the overall height of the jug, and without increasing the diameter of the central cylindrical portion, the same volumetric capacity is achieved. Moreover, this is accomplished without reducing the necessary finger clearance below the handle. A surprising result in this change of dimensions is that a substantial reduction in total weight of the jug is achieved without reducing the thickness of the glass.
Referring to the drawings:
FIG. 1 is a sectional elevation showing a preferred embodiment of the invention. Superimposed on FIG. 1 in phantom lines is the outline of a conventional jug.
FIG. 2 is a sectional view taken substantially on the lines 2-2 as shown in FIG. 1.
FIG. 3 is a view of the conventional jug, shown in phantom lines, and taken substantially on the lines 33 as shown in FIG. 1.
Referring to the drawings, the glass jug generally designated has a central cylindrical body portion 11, a circular base 12, and a lower flaring portion 13 joining the circumference of the base 12 to the body portion 11. A central frustoconical neck 14 is provided at the upper end, and a ring handle 15 is formed integrally therewith. The upper flaring portion of the jug which joins the central body portion 11 to the central neck 14 is not symmetrical, but on the contrary is formed by an upper bulbous portion 16 which extends less than a full circle, and which projects above the level of the lower portion of the ring handle 15. A convex portion 17 in the region of the ring handle 15 and below it merges with the bulbous portion 16. Thus, the bulbous portion 16 and the convex portion 17 connect the neck 14 to the body portion 11. The outer toroidal surface 18 of the upper bulbous portion 16 has a radius R which is substantially smaller than the radius R which defines the outer surface 19 of the lower flaring portion 13. This surface 19 constitutes a portion of a prolate spheroid.
The phantom lines in FIG. 1 show the outline of a conventional glass jug of the same volumetric capacity. The diameter D, of the circular base 12 of the jug embodying this invention is shown to be substantially smaller than the diameter D of the base of the conventional jug. The diameter D is about sixtenths of the diameter D and the diameter D is about seventenths of the diameter D Also, the radius R; of the lower flaring portion is markedly greater than the radius R of the conventional jug. The manufacturing process for the jug of the present invention is materially improved by reason of the larger radius of the lower flaringportion of the jug.
The radius R of the surface 18 of the bulbous portion 16 is larger than the radius R, of the conventional jug, and the bulbous portion 16 extends above the lower part of the integral ring handle 15. The loss in volume in the lower portion of the jug lS thus compensated for by the increase in volume in the upper portion of the jug, except in the region of the convex portion 17 near the location of the ring handle 15. Adequate clearance around the handle is preserved. The overall height and the overall diameter remain unchanged. Surprisingly, the weight of the jug embodying this invention is substantially lower than the weight of the conventional jug, even though the volumetric contents are the same, and the thickness of the glass remains unchanged. Thus, the improvement in the manufacturing process made possible by the large radius R is achieved without sacrifice'of height limit or maximum diameter limit, and indeed results in a reduction of weight for the same thickness of glass.
Having fully described my invention, it is to be understood that I am not to be limited to the details herein set forth, but that my invention is of the full scope of the appended claims.
Iclaim:
