FRANK ONEILL, JR., OF NEW YORK, N. Y., ASSIGNOR T0 EMPIRE HOOD SEAL COR- ronn'rron, on NEW roux, N. Y.,

A conrona'rron on NEW YORK CONTAINER COVER Substitute for application Serial No.

This application is a substitute for my application, Serial No. 149,661, filed Nov. 20, 1926.

My invention relates to covers or closures 5 for containers,--milk bottles or jars for example, my object stated in a general way being to provide a cap or cover which in the form which I now regard as the best embodiment of the invention will have the Characteristics of closing the container in a sanitarily efiicient manner, will be tamper-proof in that it will reveal that it has been opened after original application, may be made and applied as a unitary thing, which after being first removed can be replaced and continued in use to rotect the container contents until used, an which withal will be simple, so that its manufacture and application to the container will be inexpensive. M invention consists in whatever is described y or is included within the terms or scope of the apnded claims.

In the drawings I show various embodiments of my invention constructed for use witha bottle or container of common construction, havin a flange with curved surfaces around t e mouth thereof, but of course, my invention is not to be restricted to. any particular form or design or container, nor to a container made of any particularmaterial. With this explanation I will describe the figures of the drawings, and explain in detail the constructions therein shown.

In the drawings:

Fig. 1 is a top plan view of a. cover blank I made of readily foldable. material, such as heavy paper or thin metal, in a fiat or sheet form but with the necessary incisions or cuts and scores for its manipulation in application to the container;

Fig. 2 is a section onthe line 22 of Fig. 1 showing the blank after it has been sha d to conform to the container top, but be ore the securing and sealing parts have been folded and united.

Fig. 3 is a similar section showing the cover after it has been secured to the con tainer;

Fig. 4 is a top plan view;

149,661, filed November 20, 1926. This application filed. February 16, 1929. Serial No. 340,409.

Fig. 5 is a side elevation of what is shown in Fig. 4;

Fig. 6 is a similar view illustrating a different embodiment of my invention; A

Fig. 7 is a horizontal section showing the steps in securing the cover to thecontalner;

Figs. 8 and 9 are detail views in section showing the intermediate and final steps in Joining and sealing adjacent ears or tongues;

Figs. 10 and 11 are horizontal sections .in detail showing the intermediate and final stages of securing adjacent ears or tongues somewhat differently from what is shown in Figs. 7 to 9.

Fig. 12 is a vertical section of a different embodiment of my invention shown as se cured to a container;

Fig. 13 is a top plan view of part of a blank; used for the cover shownin Fig. 12;

Fig. 14 is a view similar to Fig. 12 of another embodiment of my invention;

Fig. 15 is a detail view in section illustrating the parts and stages in the operation of joining overlapping tongues or projections by tubular rivets;

Figs. 16 and 17 are detail views in horizontal sections and elevation of a form of joining and sealing connection between con tiguous ears or tongues which may be used.

As will be seen by reference to Figs. 1 and 13, I produce a blank or foldable sheet material which in the form shown is substantially square in contour and which may be said to have a circular central portion bounded by a circle that includes arcuate cuts or incfions, 10, and which is surrounded on the four sides and at the corners of the square with tongues there being at each of the four corners a radial tongue 11, and at opposite sides of each radial tongue, 11, two tongues, 12, which in the application of the cover constitute a cooperating pair that are brought together over the intermediate radial tongue, 11, when the latter is bent down over the neck of the bottle or container, and are joined one to another by interengaging portions or rivets or other fastening means, and thus when all of the tongues, 12, around the container arejoinedthey constitute a band below the flange around the container mouth,

and tightly engaging the exterior of the consanitary manner attaching, and in effect sealing, the cover upon the container.

hat I have referred to as the circular portion of the blank by suitable dies is depressed at the central portion and given a contour in cross section as shown for example in Fig. 2, to enter the mouth of the container and conform to the flat and curved surfaces at and adjacent the mouth, a concavo-convex circular rim, 13, being thus provided from which the tongues, 11 and 12, project horizontally ready to be folded down over the sides of the container neck, and joined as has been described. Numerous radial or radially extending scores or creases, 14, are formed in the blank as shown in Figs. 1 and 13 to facilitate the ready bending of the material to form the circular rim, 13.

As shown in Figs. 7, 8 and 9 the ears, 12, of a pair are provided with holes 15, and being folded outward as shown in Fig. 7 are brought together over the down-turned radial tongue, 11, and by a suitable tool are interfolded and interlocked upon one another to enable which operation the holes, 15 are provided, and the intermediate and the final steps of this operation being shown in Figs. 8 and 9 aswell as in Fig. 7. During the intermediate operations, the ears project radially, and the final act is to fold the new securely interlocked ears against the side of the container neck, as shown clearly in Figs. 5 and 7.

As shown in Figs. 6, 10 and 11, the overlapping portions of the ears provided with holes may be interlocked by a simpler treatment, as by pressing the portion, 16, of one ear adjacent its hole through a larger hole in the other ear, and doubling or folding over upon the latter adjacent its hole the projecting part of portion, 16.

As shown in Figs. 14 and 15, the overlapping portions of the ears may be 'oined by a tubular rivet, 17, that is insert-e through the ear holes and upset or riveted.

As shown in Figs. 16 and 17, each ear of a pair may be provided with a projection, 18, that as shown clearly in Fig. 16, may be folded over a contiguous portion of the other ear, and the overlapping portions interlocked by forcing a teat, 19, on the projection 18, into a hole, 20, in the adjacent ear. This arrangement makes a most efficient clamp and seal which discourages tampering, because both projections, 18, must be disengaged and as the parts are small the likelihood of injury or destruction which may reveal tampering is very great.

As shown in Figs. 2 and 3, a lining, 21, of soft flexible material may be applied to the inner surface of the cover to make a more effective seal than would heavy paper give when used alone, should it be desirable to take this further precaution.

As shown in Fig. 4, by the letter A a grade or trade-mark or other matter may be embossed or printed to show the grade or contents of the container or for advertising or other purposes.

Referring to Fig. 12 the central mouth closing portion of the cover may be a disc, 22, of cork or other material separate from the rest of the cover, a central hole, 23, being punched or formed in a cover blank, as shown in Fig. 13 with inwardly projecting spurs, 24, which penetrate and are clinched upon the disc, 22. As shown in Fig. 14, the mouth of the container may be closed by a separate disc, 25, of cork or other material which is entirely unconnected with the cover, 26, which includes a flat portion that reaches across the mouth of the container and which by tongues corresponding to the tongues, 11 and 12, is secured to the container.

It may be an advantage to combine in one cover several different forms of connections between the tongues, 12 and 12, as shown in Figs. 1, 3 and 6.

The construction of my cover is such that it can be readily applied and secured to the container by an automatically acting device or mechanism which, of course, it is not necessary to show and describe, because it forms no part of the present invention.

WVhat I claim is:

1. A container cover of foldable material having marginal portions bendable downward over the side of the container and comprising adjacent portions adapted to overlap and be joined where they overlap, the overlapping portions having complementary securing means integral therewith and which are a part of the cover before its application to a container.

A container cover of foldable material having marginal portions bendable downward over the side of the container and comprising adjacent portions adapted to overlap and be joined where they overlap and having the overlapping portions provided with complementary securing means, and having situated between said portions that are adapted to overlap members that are likewise bendable downward over the side of the container.

3. A container cover of foldable material having marginal portions bendable downward over the .side of the container and comprising adjacent portions adapted to overlap and be joined where they overlap and having the overlapping portions provided with complementary securing means, and having situated between said portions that are adapted to overlap members that are likewise bendward over the side of the container and comprising adjacent portions adapted to overlap and be joined where they overlap, said cover comprising a circular central portion at the periphery of which said marginal portions are situated, said circular portion being defined in part by arcuate slits and said marginal\ portions extending circumferentially with free ends opposite.

5. A container cover of foldable material having marginal, portions bendable downward over the sideof the container and comprising adjacent portions adapted to overlap and be joined where they overlap, said cover comprising a circular central portion at the periphery of which said marginal portions are situated, said circular portion being defined in part by rrcuate slits and said marginal portions extending circumferentially with'free ends opposite, said adjacent portions consistin of a plurality of pairs haying differentjolning means for respective airs. p 6. A container cover of foldable material havin on its mar 'n a plurality of radially exten ing bendab e tongues and adjacent each tongue opposing bendable tongues that extend in directions crosswise of the intermediate tongue adapted to overlap said intermediate tongue and each other and be joined where they overlap.

7 A container cover of foldable material havin on its mar 'n a plurality of radially exten ing bendab e tongues and adjacent each tongue opposing bendable tongues that extend in directions crosswise of the intermediate tongue adapted to overlap said intermediate tongue and each other and be joined where they overlap, and having complementary joining means.
