CLOSURE FOR PAPER ICE CREAM PACKING CONTAINERS AND THE LIKE Filed June 11, 1932 Patented Sept. 8, 1936 UNITED STATES PATENT OFFIE CLOSURE FOR PAPER ICE CREAM PACKING CONTAINERS AND THE LIKE Application June 11, 1932, Serial No. 616,596

20 Claims.

This invention relates to covers for paper ice cream cans and the like, and this application is a continuation in part of our copending application, Serial No. 540,282, filed May 27, 1931.

Some difficulty has been experienced in removing tops from paper ice cream cans, this difflculty arising particularly by reason of expansion of the can body incident to the freezing of the ice cream therein, with the result that the cover becomes tightly locked or frozen to the can body.

It is, therefore, the object of the present invention to provide an improved end closure for a can body, whereby the can may be easily opened so as to provide full access to-the contents. A further object is the provision of such an end closure which affords a reinforcement and protection for the end of the can body both before and after the can is opened. It is also an object of the invention to provide such an end closure which will be securely fastened to the can body but which nevertheless may be easily applied without special tools or equipment for that purpose.

Other objects and advantages of the invention will be understood by reference to the following specification and accompanying drawing in which a closure structure embodying a selected form of the invention is illustrated.

In the drawing:

Fig. l is a top plan view of a can cover illustrative of the invention.

Fig. 2 is a side elevation of same applied to a can body, a portion being broken away and shown in section.

Fig. 3 is a section on the line 3-3 of Fig. 2.

Fig. 4 is a section showing the preferred position on the can body of a part of the cover which remains on the can body after another part of the cover is removed.

Fig. 5 is a view similar to Fig. 2, but showing a modified arrangement.

Referring now to the drawing, it will be understood that the closure structure disclosed in Figs. 1 to 4 inclusive is in the form of a top closure or cover adapted for use in connection with a substantially cylindrical container having a tubular body 5, which preferably is formed of paper board or similar material in such fashion as to be flexible or collapsible to a flattened form for conservation of space when the container is stored or shipped in knocked-down condition prior to use.

The improved closure for the can body 5 includes a relatively rigid annular member 6 which has its margin seated in the recessed seat 9 of 10 the rim.

The cover disk 10 may be readily inserted into place from the inside end of the rim, this being accomplished by inserting the disk in an angular manner and forcing the same past the inwardly l5 bent marginal lip portion H- of the rim. It will be understood that the flexibility and compressibility of a paper board disk readily permits sufiicient distortion thereof to allow it to be inserted into the outwardly recessed seat 9, as described. It will be understood that the cover disk I0 is consequently retained in the annular member 6 so that the closure may be applied to the can body by inserting the upper margin of the body into the rim 6, thereby placing the cover disk held in can closing position by seating it on the end of the can body, where it is held by the inwardly extending top flange'portion 8 of .the

The cover disk I0 is provided with scoring or other weakened lines, such as indicated at H. In this instance, the scoring is shown as being arranged to provide a central portion l3 of the disk, spaced inwardly from the periphery of the disk, and outer or peripheral sections I 4, l5, and

I6, respectively.

When a cover of the type described is used on a paper board can in which ice cream is frozen, it is found that the can body is slightly expanded by the freezing of the contents so that the metal rim 6 of the cover, especially at its bottom edge flange I I, becomes a tight fit on the can body and cannot be readily removed. The lower inturned marginal portion ll of the annular member may yield outwardly somewhat as an incident to expansion of the can body so that the can body will not be cut or otherwise damaged when expanded.

When it is desired to have access to the contents of the can, some portion of the scoring I2 is broken through, by means of a knife or other implement, if necessary, and the disk broken into sections which may be separately removed from the rim without difllculty. While no particular method need be followed in breaking the scoring, it is suggested that it may conveniently bedonebybreakingthecoveratthescoring at one of the corners of the triangular central portion II, which may then be easily lifted out of the cover disk, whereupon the other sections H, II, and It may also be readily separated from each other and removed from the rim. It will, of course, be understood that the weakened score lines above described may be arranged in any manner to facilitate removal of the cover disk outwardly or upwardly from the metal rim either in sections or in one piece.

When the cover disk is thus removed, the upper end of the can body 5 is reinforced and held in shape by the remaining metal rim 6, and the inwardly extending flange 8 thereof, which is preferably turned downwardly and outwardly as shown, serves to provide a smooth, non-cutting and durable end for the can body. After removal of the disk the rim may be pressed downwardly on the can body until the flange portion 8 rests on the end of the can body, as shown in Figure 4, thus providing the can body with a smooth and durable edge over which an ice cream scoop may be drawn to remove surplus ice cream carried up by the scoop. It will be observed that when the parts are positioned as in Figure 3, there is practically no space between the rim flange 8 and can body in which ice cream might be trapped, or which would be objectionable for any other reason.

The annular member 6 may be formed from a metal strap having a considerable degree of resiliency yet of sufllcient ductility to permit its being shaped into the ring form, and the ends of the strap may be joined in any suitable manner so as to form an endless band or collar.

One suitable manner of connecting the ends of the strap is indicated in Figs. 2 and 3 wherein the ends of the strap are shown overlapped. At the end of the strap which overlies the other end, the bead portion 8 is cut away as indicated at 2i so as to provide an abutting joint 22 between the ends of the beaded portion of the strap. The underlying strap end is provided with an opening 23 and the overlying strap end is provided with a U-shaped slot 24 which leaves a tongue 25 normally disposed in the plane of the strap of which it forms a part. In joining the two ends of the strap, the tongue 25 is passed through the opening 23 substantially as indicated in Fig. 3.

However, it will be understood that the thickness of the strap forming the annular member is materially exaggerated and that the offset relation of the tongue 25 with respect to the strap por-- tion from which it is formed is necessarily exaggerated. In actual construction, the thickness of the metal strap is so slight that the three ply thickness at the described joint is not sufiicient to cause a noticeable bulge in the annular member such as appears in Fig. 3.

In the modification shown in Fig. 5, the upper end portion of the can body is outwardly rebent to provide a two-ply upper end portion at i1 which may reinforcethe upper edge.

An annular member such as the member 6 may be mounted on the can body formed as shown in Fig. 5, the inturned flange or lip portion ll then looking behind the shoulder l9 formed by the rebent portion ll of the can body. However, in Fig. 5, a modified metallic rim construction is shown. The rim there disclosed includes a side or body part 26 and an inwardly extending top flange portion 21. As shown, the top flange portion 21 is provided with a bead-like formation 2| at its inner margin so as to provide a smooth, non-cutting edge such as above referred to. A

cover disc 20 is positioned in the annular member between the top flange member 21 and a series of inwardly oflset portions such as punch pricks 20. The series of inwardly offset portions 30 cooperates with the flange portion 21 to form, in

effect, an inwardly facing groove for receiving the thickness of the cover 29.

The lower marginal portion of the rim 26 is bent inwardly, preferably to a re-entrant angle relative to the body portion 26 of the rim, substantially as indicated at 3 i. By thus bending the flange or lip portion 3|, positioning of the rim on the can body is facilitated since the flange forms a conical or funnel-like guiding surface for steering the end of the can body into the rim as the latter is telescoped thereon, the upper end of the body portion being flexed inwardly sufficiently to permit the shoulder l8 to pass the flange 3!. If desired, the flange portion 3| may be turned inwardly at right angles to the rim portion 26, but the described upwardly converging form is preferable.

For joining the ends of the strap from which the annular member 26 is made, a joint such as shown in Fig. 2 may be employed or the joint may be made by providing one end of the strap with a tongue 32 and the other end with an opening 33. The beaded portion of the strap may be cut away in the manner above described in connection with Fig. 2 so as to avoid overlapping such beaded portions. The tongue 32 is adapted to be inserted in the opening 33 and rebent so as to lock the parts in assembled relation.

It will be observed that when the rim is in place on the end of the can body, the tongue 32 in the structure shown in Fig. 5 and the tongue 25 in the structure shown in Fig. 2 will be clamped tightly against the outside of the can body whereby the tongues are prevented from bending in such a manner as to permit separation of the ends of the rim.

..Whe n the construction is as shown in Fig- 5, the annular member will be more positively locked to the can against removal therefrom while, at the same time, being readily adjustable to final seated position as illustrated in Fig. 4. It will be noted that the inturned lower flange portion may be of such width that it will not engage the side wall of the can body proper. Hence, there will be no resistance at this point to downward movement of the rim to finally seated position when the cover disk is removed.

Changes may be made in the described construction without departing from the spirit of the invention, the scope of which should be deter mined by reference to the following claims, the same being construed as broadly as possible consistent with the state of the art.
