cnosonn ron BOTTLES.

My invention relates more particularly to that class of closures for'bottles, jars, and other rigid containers in which the bottle neck, for example, is enlarged by a peripheral head or otherwise around the mouth of the bottle, and the ca ,for example, that known as the Crown cap, which is provided with a cork or other lining in its crown to seal the mouth of the bottle, is crim ed or compressed to form-a'contracted rim ound tightly around the neck of the-bottle, and secured against displacement thereon by the enlargement around the mouth-of the bottle. The Crown cap has heretofore generally been removed when desired by a special tool for the, purpose which often distorts the cap in removal so that it cannot be used again even for temporarily closing the container, as when only part of the contents is to be used at a time. The primary object of my invention is to provide a neck for bottles, jars, and similar containers so formed that the. cap, when 'crimped or compressed thereon, as by means of the ordinary crimping machines in com- '.mon use, will be securely held inplace against leakage and displacement and yet can'be' easily removed by hand without the use of an tool, and after removal can be easily rep aced on the neck for temporarily closing-the container when onlypart of its contents have been used.

To this and other ends, my invention consists broadly of a container, for example, a bottle, having a neck formed with peripherally and upwardly inclined beads or shoulders to engage inward projections, or some of the' corrugations, if a Crown cap, on the inside of the rim thereof and lift the cap off the neck as the cap is turned, and with up 'ivardly and outwardly "inclined parts by whichthe'rim of the cap, when crimped or contracted around the neck, is locked in place and which, when-the cap "is turned by hand, will act to expand the rim and ease the liftin of the cap off the neck.

y invention also consists more specifically, in forming the peripherally and upwardly inclined shoulders on the'upper sides of. beads raised "around the neck of the bottle, the undersides of which when the several beadsoverlap, serve with the outwardly inclined" parts ofthe neck, to enga e the in ward cap projections and lock t ecap in place.

Application filed April 17, 1928. SerialNo. 270748.

The inclined shoulders on the neckmay also bev formed of inclined grooves in the neck.

The broad invention and the specific form thereof above briefly stated ,'are not claimed herein but are described and claimed in a separate application for patent filed by me April 17th, 1928, Serial No. 270,7 50.

The present application is specifically for I another specific form of my broad invention described but not claimed in my said other application, and consists in making the outer sides of the inclined beads instead of or together with the body of the neck between the same, inclined outwardly and upwardly, so that'the inclined parts of the neck formed by said outer sides of the beads will serve to lock the capin place when crimped or contracted thereon and to spread the rim of the cap and e'ase its lifting and removal when turned and lifted by the upwardly and peripherally inclined shoulders formed by the upper sides of the beads.

In order that my invention may be fully understood, I shall first describe in detail the mode in which I at present prefer to carry this invention into practice, and then particularly point out the invention in the claim. Reference is to be had to the accompanying drawings forming part of this application in which like parts are designated by the same numbers in all the figures.

Figure 1 is a sectional side view of a bottle neck with Crown cap embodying my invention.

Figure 2 is a cross sectional view of the same on the line 2-2, Figure 1.

Figure 3 is a side view of said bottle neck.

In the drawings, 19 designates the bottle neck and 18 the body thereof which may be cylindrical as shown or slightly inclined upwardly and outwardly. Y

The bottle neck is formed with beads, the upper sides 21 of which are inclined up- 'wardly and peripherally-toward the mouth- 23 of :the bottle to form upwardly and peripherally inclined shoulders.

The outer sides 22 of the beads are inclined upwardly and outwardly toward the mouth of the bottle to form upwardly and outwardly inclined parts of the neck.

When the rim 24 of a Crown cap 25, for example, is crimped or contracted around the neck 19 thus formed, the upwardly and 1 the internal projections on the rim 24, en,

outwardly inclined arts 22, co-operate with the inward projectlons formed by the corrugations on the inside of the rim 24, some of "which enter the grooves between the beads to lock the cap securely on the neck.

When the cap is turned by hand some of gage and ride upward on the upwardly and peripherally inclined shoulders 21 of the beads and lift the cap, which is slightly flexible, off the neck.

At the same time the upwardly and outwardly inclined parts 22 of the beads on the neck act to spread the flexible rim 24 of the cap and facilitate the removal of the cap from the neck.

As the cap, being flexible, is not unduly distorted by the lifting and spreading process, it, after removal, can be easily slipped over the cap-expanding and, securing parts 22 and replaced on the neck temporarily to cover the remaining contents of the bottle when only a part thereofhas been used. It is evident that this improved form of container neck may be used with other caps than Crown caps, which have a rim adapted to be contracted below the mouth of the bottle and interior projections on the rim which will engage the upwardly and peripherally inclined lifting shoulders on the neck.

It is also evident that other changes may be made in the practice of my invention will engage the inward projections of a cap crimped or contracted thereon and lift the cap off the neck when turned, and the outwardly inclined parts will assist in locking the cap when contracted on the neck, and ease its lifting by the shoulders when it is turned.

In testimony whereof I afiix my signature.

ANTHONY F. MCDONNELL.
