METAL BOTTLE Filed Jan. 6, 1956 INVENTOR,

ATTORNEYS Patented May 9, 1939 UNITED STATES NT OFF! 1 Claim.

The invention relates to bottles.

The object of the invention is to provide an all metal bottle having a cap anchoring means and suitable for any potable beverage and having distinct advantages over the usual glass bottle in that it will not break, is lighter in weight so that shipping charges thereon are lower, and in the case of certain beverages they may be pasteurized in bottles of any size which would be quite impractical or even impossible with a glass bottle of like size.

A further object of the invention is to provide a bottle formed of a unitary piece of metal, noncorrodible to or by its contents, having a contracted neck provided with a beaded mouth, the thickness of the metal forming the mouth or point of wear by sealing device being greater than the side walls.

A further object of the invention is to provide a bottle formed of a single piece of metal in which the contracted neck has a cap or other suitable sealing device anchoring means and in which the turned over edge forming said means has a fiuid tight engagement with the adjacent portion of the neck.

The invention further consists in the new bottle hereinafter described and more particularly defined by the claim at the conclusion hereof.

In the drawing:

Fig. l is a vertical sectional view of a bottle embodying the invention;

Fig. 2 is a detailed sectional view of the neck portion of the bottle during manufacture;

Fig. 3 is a detailed sectional view of the neck portion of the bottle in its finished state with apparatus used in finishing the same;

Fig. 4 is a detailed elevation view of the neck of the bottle with a closure applied thereto.

Referring to the drawing, the numeral 5 designates the bottle embodying the invention which has a smooth interior wall, relatively heavy bottom 6, a cylindrical wall I, a contracted or conoidal breast 8 a tubular neck 9, and a cap or other sealing device receiving bead ID.

This bottle is formed of a non-corrodible metal such as aluminum, aluminum alloys, stainless steel, or other metal with non-corrodible surface, or other suitable metal and is formed from a single piece of such metal, the metal blank or lump first being subjected to a drawing operation in suitable dies to form a closed end tube whose bottom Wall may be relatively thicker than the drawn sides of the tube which extend upwardly as indicated by the dotted lines H.

The bottom portion 6 is strengthened or rein forced by being made thicker as compared with the side walls or it may be of the same thickness as said walls and strengthened by corrugations such as the radially disposed corrugations [2 shown in the drawing. The bottom is also preferably concavely formed to better resist the high pressures though it may be otherwise formed if desired.

The breast 8 may be somewhat thinner than the bottom but preferably thicker than the wall 1. The closed end tube previously described is subjected at its upper or open end to a spinning operation to form the breast wall 8 and the neck 9 of the bottle. In addition to the spinning, the wall of the neck 9 may be further thickened by a compacting of the fibres thereof during the spinning operation. This compacting operation makes the neck thicker than the breast, and the outer end of this neck is spun over to form a bead initially as shown at 13 in Fig. 2. This comp-acting operation may be applied only to the outer edge of the neck that forms the bead l3. With the bead formed by an ordinary spinning operation, as shown in Fig. 2, there is a chance for bacteria and dirt and other foreign matter to collect between the lower edge of the bead and the neck, and to prevent this occurring and obviate the necessity of special cementing, brazing, or metal filling operations the neck of the bottle is next subjected to the action of a pressing operation brought about by the insertion of the neck 9 of the bottle in a mandrel Hi and the pressing of the bead to final form by a rotatable forming and pressing wheel l5 which may be mounted on a shaft l6 and is adapted to be moved into engagement with the bottle, the bottle and the mandrel [4 preferably rotating while the pressing member i5 is operating on the bottle. This pressing member is shown as in the form of a wheel having a bead forming groove H and a neck engaging surface [8 extending from one end of said: groove. When this member l5 exerts pressure on the bead in the form shown at i3 in Fig. 2, it acts to work the metal at the outer edge 19 of the bead forwardly and inwardly as at 2B in Fig. 3 into a metal to metal contact with the side of the neck so that a fluid tight joint between these parts is assured and no pocket is left for the accumulation of dust, bacteria, and other foreign matter.

With the bottle thus formed in one piece the usual bendable metal cap 2| or other sealing devices may be used by turning or crimping over the bead ID, as shown in Fig. 1, or other suitable sealing devices may be applied to the mouth with the same facility that such closures are secured to glass bottles. It is also to be noted that a suitable fitting or tapping device may be applied to the bottle and engage below or at the point 20 formed by the bead. This metal bottle may be as readily cleaned as a glass bottle and will, as previously noted, stand the relatively high temperatures to which bottles of large size have to be subjected for pasteurizing their contents without danger of breaking. Where the bottle is, as previously noted, made of suitable aluminum alloy or other suitable non-corrodible metal or other metal with non-corrodible metal surface, it is not necessary to line the same to prevent its contamination of or by potable beverages including beer and ale which maybe stored therein.

I desire it to be understood that this invention is not to be limited to any particular form or arrangement of parts except in so far as the same are included in the appended claim.

What I claim as my invention is:

As a new article of manufacture, a bottle of a unitary piece'of metal, 'non-corrodible to or by its contents, having a bottom, side walls, a contracted breast, and a neck having a beaded mouth, the edge of the metal formingthe bead having embedded fluid tight engagement with the adjacent wall of said neck.
