CLOSURE Non. ooN'r-niNEias.

Application filed April 17, 1928. Serial No. 270,750,.

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 cap, 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 crimped or compressed to form a contracted rim bound 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 desiredby 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 contalner, as when only part of the contents is to housed at a time. L'

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 common use, will be securely held in place against leakage and displacement, and yet can be easily removed byhand without the useo'f any tool, and after removal can be easily replaced on the neck for temporarily closing the container when only part of its contents have been used. v

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 acrown cap, on the inside of the rim thereof and lift the cap off the neck as the cap is turned, and with upwardly and outwardly inclined parts by which the rim of the cap, when crimped or contracted around the neck, is locked in place and which, when the ca is turned by hand, will act to ex and the rim and ease the lifting of the cap 0 the neck. 7

My 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 beads overlap, serve with the outwardly inclined parts of the neck, to engage the inward cap projections and lock the cap in place.

The inclined shoulders on the neck may also be formed of inclined grooves in the neck.

Further the shoulders maybe made in pairs converging downwardly on the neck so as to enga e the inward projections on the cap and 1i t the cap whenthe cap is turned in either direction. v

This alternate specific construction, al-

though claimed broadly herein,is not claimed specifically herein, as it forms the subject of a separate application for atent filed by me April 17 1928, Serial No. 2 0,749.

The upwardly and outwardly inclined parts to lock the crimped rim andexpand the same and ease the removal of the cap when lifted by the peripherally inclined shoulders, may be formed on the body of the neck intermediate the lifting shoulders, as

described and claimed herein, or they maybe formed by making the peripherally and upwardly inclined beads previously referred to, I

themselves inclined outwardly and u wardly toward the neck, the body of the neck etw'een these upwardly expanding beadsbeing cyli'n drical, instead of upwardly flaring as previousl described. 7' e although claimed broadly! herein, is .not claimed specifically herein as it forms the subject of a separate application for atent T is latter alternate specific construction,

filed by me April 17, 1928,- Serial No. 2 0,748.

My inventionalso consists in forming the inward projections, in the form of corruga tions on the crown cap, with upwardly and peripherally inclined depressions to accommodate the inclined lifting shoulderson the neckagainst which the corrugations abut, as

distinguished from those corrugations which properly engage and. ride on the shoulders.

Myinvention also consists in forming the inward corrugations on the cap with vertical deiptressions extending to the top thereof to so en their action against the abutting shoulders on the neck.

My invention also com ises other features which will be hereina te claimed.

In order that my invention may be fully understood, I shall first describe in detail the r described and p I mode in which I at present prefer to ca the -shown in Figures 1 and 2.

invention intopractice and then particu arly point out the invention in the claims.

Reference is to be had to the accompanying drawin formingpart of this ap lication in whic like parts are designate by the same numbers in all the figures.

The bottle shown in the drawings is designed to be sold by the makers, as a new and useful article of manufacture, to bottlers of beverages and others, who'purchase caps therefor, such as crown caps which are sold by cap makers and others independently, and securethe caps to the bottles by means such asthe capping machines in common use The improved bottle shown is designed particularly for crown caps, but may be used with any other suitable "cap having a rim adapted to be crimped or otherw se contracted around the neck of the bottle and provided with internal projections which will engage the inclined lifting shoulders on the ca expanding neck.

Additionally to lock the cap on the neck when crimped or contracted thereon, and to ease its lifting and removal by the shoulders when turned, the body of the neck between the beads 12 is here illustrated as flaring so that the upwardly and outwardl inclined parts formed thereby will'secure the cap crimped or contracted around the same against accidental upward dis lacement, and will evenly spread the rim of t e cap, and ease its removal when turned without the destructive distortion of the cap caused by the tool ordinarily used for this purpose.

This specific form of my invention, as previously stated, is specifically claimed in a separate application for patent filed' by me April 17, 1928, Serial No. 270,7 48.

In Figures 8, 9, and 10, I have shown another specific form of my broad invention 1n peripherally and upwardly 1nclined cap-lifting shoulders 26 are formed in pairs converging downwardly from the mouth of the bottle so that some of the inward corrugations 27 of the crown cap, here 24 of the crown'cap 25, when illustrated for example, 'when crimped around this form of neck, will enter between the converging pairs. of shoulders 26 and when the cap is turned in either direction, the corresponding ones of the pairs of converging shoulders 26 will engage the cap projections 27, and lift and remove the cap from the neck. The arts 28 of the neck be-' I prefer to make the converging shoulders 26, deeper at the bottom as shown where the initial greatest resistance to removal is met,

and to lessen their depth gradually as they approach the mouth, to make a better fiIllSll.

As previously stated, the specific form of my broad invention, shown inFigures 8, 9, and 10 is described and claimed specifically in another application for patent filed by me April 17, 1928, Serial No. 270,749.

It is evident that other variations may be made in the specific performance of my'broad invention without de arting from the boundaries thereof as de ned by the following claims.

I claim as my invention:

- 1. A bottle or other. container having its neck formed with shoulders inclined peripherally and upwardl toward the mouth to be engaged by inwar projections on the rim of the cap and lift the same when turned and with parts inclined outwardly and upwardly towardthe mouth to engage and lock the rim of the cap when contracted around the neck and to expand the rim when lifted by the inclined shoulders.

2. A bottle or other container in accord with claim 1, in which the inclined shoulders are formed by the up er sides of beads raised around the neck of t 1e bottle.

3. A bottle or other container in accord with claim 1, in which the inclined shoulders are formed by the upper sides of overlapping beads, the lower sides of which serve also as shoulders to engage the inward projections on the cap rim and lock the cap on the neck in co-operation with the upwardly and outwardly inclined parts around which the rim is contracted.

4. A bottle or other container in accord with claim 1, in which the upwardly and out wardly inclined parts are formed b the u wardly and outwardly flaring bo y' oft e neck'between the upwardly and peripherally inclined shoulders.

5. A bottle or other container in accord with claim 1, in combination with a cap having a rim to be contracted around the upwardly inclined shoulders and outwardly inclined parts, said rim having inward projections to engage the upwardly inclined shoulders and outwardly inclined parts so as to lift the ca and expand the rim when the cap is turned? 6. A bottle or other container in accord with claim 1, in combination with a ,cap having a rim to be contracted around the upwardly inclined shoulders and outwardly inclined parts, said rim having inward corrugations to engage the inclined shoulders and outwardly inclined parts, the inward corrugations being formed with inclined transverse depressions to accommodate the abutting inclmed shoulders.

7. A bottle or other container in accord with claim 1, in combination with a cap having a rim to be. contracted around the upwardly inclined shoulders and outwardly inclined parts, said rim having inward corrugations to engage the upwardly" inclinedx shoulders "and outwardly inclined parts, the

inward corrugations beingformed with' depressions rising to their top to ease their action on the inclined shoulders.

In testimony whereof I aflix my signature.
