BOTTLE.

Application filed January 13, 1925. Seriallio. 2,098.-

The present invention relates to improvements in bottles. r

The prii'nary object of this/invention is to provide a bottle, especially adapted for use in dispensing milk, or the like, and is so formed that it will fit all types and makes of automatic bottling machines.

A further object of'the invention is to provide a milk bottle having fiat sides and a cavity or vacuum cup in its bottom which is formed with a surrounding bead or flange.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawing forming a part of this specification and in which like numerals are employed to designate like parts throughout the'same,

Figure 1 is an elevational view,partly broken away, of the bottle embodying this invention,

Figure 2 is a bottom plan view of a bottle of the type shown in Fig. l and having a cavity or vacuum cup formed in its bottom and surrounded by a circular head or flange,

Figure 3 is a transverse sectional view taken uponline IIIIII of Figs 1, and

Figure at is a bottom plan view of a bottle of the type'shown in Figs. 1 and 3 with a square cavity or vacuum cup formed in'its bottom and surrounded by a square bead on In the drawing, wherein for the purpose of illustration is shown a preferred embodiment of this invention, the numeral 5 designates the conical neck portion of the bottle having the rounded bead 6 formed at its open end, as best illustrated in Fig. 1. The

body portion of the bottle is joined to the conical neck portion 5 by the gradual curved portion 7 and is formed with the four orv more flat side walls 8. By inspecting Fig. 3,

. it will be seen. that the cylindrical portions 9'-. join or unite the flat'side walls 8 and that; these cylindrical portions thickness. :as' the said side walls.

In Figs. 1, 3 and 4, the bottom of the bottle is illustrated as having the square cavity or vacuum cup 10 formed therein and surrounded by the square bead 1I having the curvedor cylindrical outer face of a less-radius than the radii of the cylindrical edges 9. The inner wall of the head 11 that depends from the bottom wall of the bottle abruptly 9 are of the same merges into the bottom wall to define the vacuum cup 10.

In Fig. 2 the bottle is illustrated as having the circular cavity or vacuum cup 10 which is surrounded by the circular bead 11'.

As will be understood from the drawings,

the body portion of the bottle presents a cross-section of polygonal form with sets of opposing plane walls and with the walls .of

one set extending at substantially right anthus restrainthem frommovement. In addition to this, however, the bottom of the bottle is provided with an annular Wall, symmetrical 1n contour, and curved 1n cross-see tion to provide a seating plane for the bottle that is spaced a material distance from the outer plane of the main bottom portion, the annular wall having substantially uniform dimensions throughout thev annular length ofthe wall, that portion of such annular wall which extends from the seating plane .to: the

and upsetting of bottles,'especially-when thg 7 latter are being filled in filling machines, after being filled. If the filling machine be provided with a vacuum holding means, the

seated bottle is more firmly held to its seat owing to the fact that the volume of air ca-' vpable of being withdrawn from this bottom plane of the bottom wall, joining the latter space is considerable,thus'increasing the effective difference of sides of the seating face. And although the effect is greatly reduced when the bottle is away from the machine, there is a tendency to produce a variation in pressure on the opsides of the seating face where the 1 posite temperature of the contents of the bottle is materially les than thatof the atmosphere, the cooling efl'ect of the contents on the considerable volume of air within the seating face provided by'the annular wall, permit;

pressure on .opposite ting a reduction of the temperature of such air and its resultant effect in reducing the pressure within such space.

It is to be understood that the forms of this invention herewith shown and described are to be taken as preferred examples of the same, and that various changes in the shape, size, and arrangement of parts ma be resorted to without departing from t a spirit of the invention or the scope of the sub-v joined claims.

Having thus described the invention, we

1. A milk bottle comprising a neck portion and a body portion, said body rtion being rectangular in cross section with the flat side walls merging into curved corner edges, a continuous beaddepending from the 7 bottom of the body portion with the u per end of the inner side wall of the head abruptly merging into the bottom of the body portion It/3.11 angle to the plane thereof to define'an inner cavity forming a vacuum cup, said bead being curved in'cross -0 the bead abruptly merging into the bottom of the body portion at an angle to the plane thereof to define an inner cavity formmg a vacuum cup, said head being curved in cross section with the radius thereof less than theradii of the curved corner edges of the bod portion, with the curved corner edges 0 the body portion set outwardly of the bead for protecting the same.

In testimony whereof we afiix our signatures.
