UNITE JOHN KELLY, OF CHICAGO, ILLINOIS.

BOTTLE CLOSURE.

Specification of Letters Patent.

Patented June 20, 1922.

Application filed October 5, 1921. Serial No. 505,575.

To all whom it may concern Be it known that I, JoHN KELLY, a citizen of the United States, residing at 5958 Washington Boulevard, Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Bottle Closures, of which the following is a specification.

My invention relates more particularly to bottle closures especially formed of pasteboard or the like and particularly adapted for use with bottles the mouths of which are formed with an annular shoulder against which the closures therefore are positioned.

My primary object is to provide a novel, simple and inexpensive construction of closure which may be readily removed from. the mouth of a bottle and replaced therein. Another object is to provide a closure which, when positioned in abottle, will serve as a protection against the breaking or chipping of the mouth portion thereof in the superposing of another bottle thereon which commonly occurs.

Referring to the accompanying drawing, 'Fig. 1 is a face view of a blank from which the closure is constructed. Fig. 2 is a face view of the closure embodying my invention. Fig. 3 is a section taken at the line 3-3 on Fig. 2 and viewed in the direction of the arrows. Fig. t is a top view of a bottle showing the closure of Fig. 2 in place thereon. Fig. 5 is a broken section taken at the line 5 on Fig. 4 and viewed in the direction of the arrows; and Fig. 6, a broken section taken at the line 6 on Fig. 4; and viewed in the direction of the arrows.

In accordance with the preferred embodiment of my invention I form the closure from a square sheet of the material of which it is desired the closure be made, as for example, the material commonly used for making the closures generally in use for closing the mouths of milk bottles. The blank referred to and represented in Fig. 1 in practiee would be cut from a relatively large sheet of the desired material. The size of the blank of Fig. 1 preferably would be such that its cross dimensions, from side to side, are the same as the diameter of the mouth of the bottle to which the closure is to be applied, above the annular internal shoulder of the bottle, and in the manufacture of the closure it is pressed, or otherwise formed preferably into the shape shown in Figs. 2 and 3 to provide the centrally circular depressed portion 7 of a diameter substantially that of the mouth of the bottle above the internal 'annular shoulder therein, this shoulder being represented at 8, and the opening in the mouth portion thereof at 9, in the drawings. The portion 7 thus extends in deflected condition relative to the corner portions 10 of the blank, these corner portions being preferably pressed, or otherwise formed, into the condition shown in Figs. 3, 4 and I The closure upon being introduced into the mouth portion 9 of the bottle becomes seated at the underside of the portion 7 upon the annular shoulder 8 and at its corner or tab portions 10 upon the upper surface of El e wall of the mouth portion as shown in As will be readily understood. the tab portions 10 not only permit of the ready reioval of the closure from the mouth of the bottle by the operator grasping any one of the tab portions 10 and withdrawing the closure, but also serve, in the particular embodiment shown, as buffers which protect the upper surface of the mouth portion of the bottle against injury as for example when one bottle is superposed on another.

The principal feature of importance in connection with my improved closure is that it requires the use of no more material than in those cases where a plain circular disk is provided for insertion into the mouth portion of a bottle, the corner portions of the blank and which are cut away in the making of a circular closure, being retained as a part of the closure and performing, preferably, the double function above explained.

What I claim as new and desire to secure by Letters Patent is:

1. A bottle-closure comprising a substantially square sheet of material shaped to form a circular central portion adapted to fit within the opening in the mouth of a bottle, and corner portions extending from said central portion and adapted to lie flat adapted to fit Within the opening in the mouth of a bottle, and corner portions eX- tending from said central portion and adapted to lie fiat on the top or" the bottle, the

closure being free from parts extending above the plane of the corner portions.

JOHN KELLY.
