3 Claims. (01. 229-55) My invention relates to new and useful improvements in a container and closure cap therefor, and more particularly to a closure cap for a readily destructible container formed of relatively thii and flexible material such as paper and primarily intended for but a single use.

The principal object of the invention resides in the provision of a closure cap adapted to be received upon the normally open end of the container, the cap including a top portion and depending flange, the flange being readily flexible and formed to provide an internal circumferentially extending recess to receive an outwardly directed flange or bead formed around the normally open end of the container.

Another object of the invention consists in so positioning the recess formed in or by the depending flange or the closure cap that the upper end or the container will engage the top portion oi. the cap when the cap is in its normal position relative to the container.

A further object of the invention resides in the formation of a closure cap of a construction and character to be positioned upon the normally open end of the container. and includr ing means cooperating with the flexible nature of the container to prevent accidental displacement or removal of the cap.

With the above and other objects in view,

which will appear as the description proceeds,

my invention consists in the novel details of construction and arrangement ofparts, described in the following specification and illustrated in the accompanying drawing, and while I have illustrated and described the preferred embodiments .of theinvention, as they now appear to me,

it will be understood that such changes may be made as .will fall within the scope of the appended claims. In the drawing:-

Fig. 1 is a transverse vertical section through a container and closure cap positioned thereon.

Figs. 2, 3, 4, 5 and 6 are fragmental vertical.

mally open end of a container of readilyflexible materi'alsuch as paper or the like, the container been provided for metal containers as well as relatively heavy cardboard containers or the like as distinguished from a container of readily flexible thin material such as paper or the like.

In the drawing l indicates the tapered body portion of the container formed 0! relatively thin paper or the like and provided at its upper end with the outwardly directed flange or bead 2 01' approximately circular cross-section and extending continuously around the mouth of the container. At 11 have indicated a bottom for the container, the lower end of the wall or body I being turned inwardlyas shown at] to engage the under surface of the bottom 3. The closure cap includes the top portion 5 and depending flange 6, the top 5 and depending flange 6 being secured together by rolling or" bending as shown at 1 to provide interlocking engagement therebetween. In that form of the invention illustrated in Fig. 1 of the drawing the flange 6 is provided with the inwardly directed head 8 to provide a circumierentially extending recess between the under surface of the top 5 separation of the top portion 5 from the flange when the cap is in use or being positioned upon the container. When the cap is placed upon the container the end of the container and the flange oi the cap will flex sufllciently to permit the cap to be snapped over'the normally open end of the container and to position the head or flange 6 of the container within the circumferentially extending recess formed by the bead 8.

In the modified forms of the invention, shown in Figs. 2, 3, 4, 5 and 6 of the drawing, the container is oi. the same construction or form described in connection with Fig. 1, however, in each instance the caps illustrated in the Figs. 2, 3, 4, 5 and '6 are of somewhat diflerent constructions. The form of cap illustrated in Fig. 2 includes the top portion 9 and depending flange Ill, the top and flange being connected by rolling or bending edge portions thereof together as indicated at II. The flange Iii is provided with the vertically spaced inwardly directed beads l2 and i3 which at the same time ing as shown at I8.

upper end of the container 2 form vertically spaced circumferentially extending recesses l4 and Hi to receive the flange or bead 2 of the container. As quite clearly shown the recess I4 is positioned just beneath the bottom 9 and when the bead or flange 2 is received in this recess the upper end of the container will engage the under surface of the top 9 for the same purpose as described for the cap in connection with the construction shown in Fig. 1 of the drawing. The additional recess I5 is provided to receive the bead or flange 2 in case the container is filled above the line of the In packaging certain commodities such as ice cream or the like often the same projects above the upper end of the container and the recess l5 is ,provided to accommodate such overfllling, but

to permit the proper connection or engagement between the cap and container so as to prevent accidental displacement or removal.

In that form of the invention disclosed in Fig. 3 the closure cap includes the top portion l6 with depending flange I! connected by rolling or bend- A groove or recess I8 is formed interiorly of the flange, just below the under surface of the top l6, and is adapted to receive the bead or flange 2 of thecontainer, the engaging the under surface of the top I6, as shown.

InFig. 4 of the drawing the closure cap includes the top portion 20 with depending flange 2| connected thereto by rolling or bending as shown at 22. Vertically spaced circumferentially extending grooves or recesses 23 and 24 are forme'din the inner face of the flange to receive the flange or bead 2 of the container. The vertically spaced recesses or grooves 23 and 24 are provided for any overfllling of the container such as described for the construction disclosed in Fig. 2 of the drawing. Normally the bead or'flange 2 will be received in the groove or recess 23, but I when there is any overrilling the flange or bead 2 will be engaged in the groove or recess 24.

In that form of the invention disclosedv in Fig. 5 the closure cap includes the top portion- 25 provided with the integral depending flange 26. Se-

2 1 which terminates belowthe under surface of" cured interiorly of the flange isa reinforcing ring thetopportion 25 to provide a recess or groove 28 to receive the bead or flange 2 on the upper end of the container as shown.

In Fig. 6 I have shown a formcf cap as in-- cluding a top portion 29 and integral depending flange 30, agroove 3! being formed'interiorly of the flange preferably by compressing the material. The groove is positioned just below the under surface of the top portion 29 to receive the bead or flange 2 on the upper end of the container with the upper edge of-the container engaging the under surface of thetop portion.

'The cap or closure will be formed of paper or other material similar to that used in the forma- 'tion of the'body or container I although, de-

sired, a somewhat heavier weight of material might be used informing thecap and more particularly the flanged portion thereof. However,

the flange or the cap will be sufflciently flexible to permit relative flexing of the flange and. container to allow the cap to be snapped over the normally open end of the container and to permit the bead or flange of the container to be received within the recess or a recess of the cap flange; It will also be understood that when desiredthecontainer and cap may be coated with suitable waterproof composition. such as paraf normally open end.

fin or the like. Further it will be noted that in each form of the invention illustrated'the depending flange or skirted portion of the closure cap will be spaced from the wall of the container thereby providing an engaging edge to facilitate removal of the cap from the body or container.

Attention is directed to the fact that in each form of the invention disclosed I provide a circumferentially extending recess within the flange of the closure cap to receive the bead or flange formed around the normally open end of the container and both the container and cap are formed of readily flexible material permitting relative flexing therebetween for proper engagement of the cap on the container.

It will be observed that in each of the illustrated embodiments of my invention the rounded lower edge of the bead at the mouth of the container cooperating with the immediately underlying ledge or wedge portion formed in or carried by the skirt of the cap will wedge the mouth of the container upwardly into the corner recess of the cap and against the under side of the top of the cap or the upper wall of the groove or recess of the skirt portion that receives the bead as the case may be. r

Having fully described my invention what I claim as new and desire to secure by Letters Patent is:-

1. In combination, a paper receptacle having a resilient lip portion formed by beading the upper edge to present a continuous outwardly extending rounded under surface projected laterally of the side of the receptacle, associated-with acap also of paper and having a top portion and a resilient skirt portion possessing a rounded seating portion, the cap being adapted to receive the bead of the body into the 'complemental seating portion thereof when the cap is forced in place so that the resiliency of the opposing body and cap parts will effect close hugging engagement of the cap with the beaded portion of the receptacle above and throughout the curved abutting surfaces thereof, the skirt portion having a part projecting inwardly and engaging under the roundedsurface of the bead of the receptacle and cooperating therewith to efiectflrm seating of the bead in a relatively upward and outward direction with respect to the cap and within therounded seating portion thereof thereby'securing the cap and receptacle together and permitting the cap to be forcibly removed without injury to either by riding action of the bead over the wall of said seating portion.

2. In combination, a paper receptacle having a resilient lip portion formed by heading the upper edge to present a continuous outwardly extending rounded under surface projected laterally of the side of the receptacle, associated with a cap also of paper and having a top portion and a resilient skirt portion and'a rounded seating portion at the juncture of the top and skirt portions, the cap being adapted to receive the bead of the body into the complemental seating portion thereof when the cap is forced in place so that the resiliency of the opposing body and cap parts will effect close hugging engagement of the cap with the head portion. of the receptacle above and throughout the curved abutting surfaces thereof, the skirt portion having a part projecting inwardly and engaging under the rounded surface of the head of the receptacle and cooperating therewith to effect flrm seating of the bead in a relatively upward and outward direction with respect to the cap and'within the rounded-seating portion I thereof thereby securing the cap and receptacle together and permitting the cap to be forcibly removed without injury to'either by riding action of the bead over the wall of said seating portion.

3. In combination a paper receptacle having a resilient lip portion formed by heading the upper edge to present a continuous outwardly extending rounded under surface projected laterrounded seating portion thereabove, the cap be- I ing adapted to receive the head of the body into the complemental seating portion thereof when the cap is forced in place so. that the resiliency of the opposing body and cap parts will effect close hugging engagement of the cap with the bead portion of the receptacle throughout the curved abutting surfaces thereof, and the edge of the reinforcing ring projecting inwardly and engaging the under surface of the bead of the receptacle and cooperating therewith to eifect firm seating of the bead in a relatively upward and outward direction with respect to the cap and within the rounded seating portion thereof thereby securing the cap and receptacle together and permitting the cap to be forcibly removed without injury to either by riding action of the head over the wall of said seating portion.
