CLOSURE FDR PAPER OR OTHER CONTAINERS Filed June 30, 1926 Patented Aug. 19, 1930 UNITED STATES PATENT OFFICE ELMER ZEIBELEY TAYLOR AND SAMUEL IPARKIN LEIDG-ARD, OF NEWARK, NEW JERSEY CLOSURE FOR PAPER OB, OTHER'CONTAINERS Application filed June 30,1926, Serial No. 119,711, and in Great Britain April 21, 1926.

4 The object of this invention is to provide a lid or closure for containers, tins, boxes and the like, particularly those which are made of paper or like material, and which lid or 5 closure shall form an efficient seal to the container until it is desired to open the latter, and shall subsequently be capable of being opened and closed as required. I

The invention is illu trated in the accompanying drawings, in which Fig. 1 is a plan view of the improved lid or closure; 1

Fig. 2 a sectional view of part of a container with the lid or closure inserted;

surge .openedto permit access to the contents, an

Fig. 4 a view similar to Fig. 2 butshowing a slight modification. I

In carrying out the invention a discA of woodpulpboard or other suitable material is employed, such disc being of the required size to fit into the groove or recess B provided for it in the upper end ofcontainer C. In

the under surface of disc A a circular line D is scored partially through the material, and in the upper surfaceanother circular line E of larger diameter is also scored; the line E may be continuous but preferably not acomplete circle but being interrupted as shown at F for the purpose hereinafter described. The scorin of either or both the lines D and E may e in the form of complete lines as shown, or may consist of a series of short dashes withintervening unscored spaces.

The object of the scored, lines D and E is that when it is desired to open the container C to which the closure has been applied, this 4 can be readily effected by inserting a fork, knife or other instrument into the scored line E and prizing up the material, when the scoring will cause such material to break between the lines D and E so that the central portion of the closure can be raised, as shown in Fig.

3, the part F where the scored line E is interru ted acting as a hinge for-the portion raised If desired a tab shaped outward extension.

56 of the line E may be formed, as shown in Fig. 3 a similar view but showing't-he closcribed'presents the advantage that it can be easily applied to the container, and sedotted lines at G, at a point preferably opposite the point F,-and which will act both as a guide for the insertion of the opening instrument and, when the opening has been started, as a tab to be grasped by the fingers to complete it, and for subsequent use when the container is to be opened or closed. I

It will be seen that the result of the breaking of the material between the scored lines is that the central or opening part of the closure will have a stepped edge, as shown clearly in Fig. 3, which in combination with the correspondingly stepped outer or stationary partof the closure will form a good joint when the opening part is subsequently closed, and prevent such opening part from being pushed down into the container.

" In the "modification shown in Fig. 4 the .scored linesD and E- are of relatively larger diameter than in the arrangement shown in Figs. 1, 2 and 3, so that when the lid is opened in the same manneras above described the edge of the opening part, formed by the scored line E, shallbe quite close to the turned over-edge H of the top of the container, so that it has to be sprung past such edge H'to open or close, such edge H thus forminga means of overcoming the spring of the mate- I rial and keeping the lid closed aft r it has once beenopened. If a tabas G, Fig. 1, is formed in line E, such tab may be of such length as to catch underthe edge H for the same purpose.

It will be seen that the closure above decured in the groove B therein by turning over the edge H of the container, and that when thus secured it forms anefiicient closure, but one which can be readily opened when it is desired to gain access to the contents, and can be closed again subsequently to protect such contents from exposure; Although the lines D and E have been described above as being of circular form, it will be readily understood that they may be of square, oval, rectangular or other configu ration, and further that the complete closure may be made of any desired shape to suit 109 that of the container to which it is to be applied.

What we claim and desire to secure by Letters Patent is 1. In combination, a container, a closure applied thereto, the wall of said container being intnrned at the upper edge and securing the closure in place, said closure having a scored line on the under side thereof to permit the central partto be raised when desired to open the container, and also having a scored line on the upper side formed and positioned so near the edge of the inturned portion of the wall that the said turned over upper edge of the container will operate to prevent the inner or central part of the closure from springing open.

2. In combination, a container, a closure applied thereto and adapted to be secured therein by turning over the upper edge of the wall of the container into contact therewith, said closure having a scored line on its under face and a scored line on its upper face disposed outside the scored line on the under face, said scored lines being so positioned that the material between them can be broken when it is desired to open the container, and the upper scored line being so formed and positioned that the edge of the opening part of the closure formed thereby has to be sprung past the turned-over upper edge of the container when it is desired to open or close the latter, as set forth.

In witness whereof we have signed this specification.
