June 13, 1944. H. cAREw CONTAINER AND CLOSURE CAP THEREFOR Filed July 30', 1940 HEPMA CA FEW Patented June 13, 1944 UNITED STATES l ATENT ormcs CONTAINER AND CLOSURE CAP THEREFOR Herman Carew, Easton, Pa; assiznor to Dixie Cup Company, a corporation of Delaware Application July 30, 1940, Serial No. 348,538
4 Claims.
My invention relates to new and useful improvements in paper container and paper closure cap therefor and more particularly to a closure cap, made of paper, for a container having a rounded bead formed around its normally open end, the principal object of the invention residing in the formation of the closure cap of relatively thin paper and in such a manner that a plurality of the caps. when desired, may be nested in stack formation. 1
Another object of the invention consists in the provision of a closure cap made of relatively thin material and including a top portion and a beaded flange or rim, the rim or flange being formed at its bottom edge with an outwardly directed bead, the bead being so positioned relative to the top portion of the cap that when the cap is placed on a container the flange or rim of the cap will flex to provide a seat for the head of the container, the bead of the container being positioned in overlapping relation with the bead of the flange or rim of the closure cap to provide resistance against removal of the closure cap from the container.
A still further object of the invention resides in the provision of a closure cap including a top portion and a flange, the flange being formed at its lower edge with an outwardly directed bead, the bead being positioned relative to the top portion of the cap so that it will form a seat for a super-posed cap in a stack of nested caps.
With theabove and other objects in view,
which will appear as the description proceeds, my invention consists in the novel details of construction, and arrangement of parts. described in the following specification and illustrated in the accompanying drawing, and while I have illustrated and described the preferred embodiments of the invention 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 drawin8 Fig. 1 is a side elevation illustrating the closure cap in position on a container.
Fig. 2 is a top plan of the closure cap.
Fig. 3 is a transverse vertical section through the closure cap.
Fig. 4. is a transverse vertical section through a stack of nested caps; and
Fig. 5 is a transverse vertical section through a closure cap and a portion of a container, the
cap being shown in its closing position on the container.
In the drawing :1 denotes generally a container made of paper and b a closure can therefor, the cap also being formed of paper. The container is shown as of tapered formation, adapting the same to be readily nested, and I indicates the side wall thereof having the outwardly directed bead 2 formed around its normally open end. p i
The closure cap b includes the top portion 3, depending flange or rim 5 and outwardly directed bead 5, formed around the bottom edge of the rim or flange. The rim or flange is formed by bending or folding as distinguished from drawing and is of pleated formation, as shown, the pleats being indicated generally at 6. The flange or rim Q is of a height slightly greater than twice the diameter of the head 5 for a purpose which will be later brought out and the interior diameter of the cap or closure between the depending flange thereof, is less than the diameter of the beaded end of the container. The bead 2, of the container, is of substantially the same diameter as thebead 5 of the closure cap.
From the above detailed description the construction of the container and closure cap therefor will be readily understood and by folding or bending the flange 6, from the blank of material used in forming the closure or cap, as distinguished from drawing the flange, relatively thin material may be used at a saving in cost. The closure caps are of upwardly tapered formation so that they may be nested'in a stack as quite clearly shown in Fig. 4 of the drawing and when in this nested formation the beads on the bottom edges of the flanges of the caps will act as seats for super-posed caps. As previously stated, the bead 5 of the cap, is so positioned relative to the top portion 8 thereof that the caps may be readily arranged in the nested stack formation. The diameter of the beaded end of the container being greater than the interior diameter of the flange of the closure cap will cause the flange to be flexed as the cap is placed on the container and this flexing of the flange will allow the bead 2 of the container to closure cap from the container. As shown, also more particularly in Fig. 5 of the drawing, the flange or rim 4 is of a depth or height slightly greater than the combined diameter or the beads 1;" and 5 and due to the flexing or the rim or flange intothe position shown in Fig. 5, the cap is held in tight engagement with the bead 2 of the container and there can be no vertical play of the closure cap relative to the end of the container.
From the above it will be noted that the position of the bead 5, with respect to the top portion 3 of the closure cap, forms an important part of my invention. The bead 2 of the containerand the head 5 of the closure cap cooperate to'present resistance against removal of the closure cap from the container and at the mally free of substantial indentations or pro- 4 trusions between the top portion and bead, and the diameter of the beaded end of the container being greater than the interior diameter of the closure cap flange, the beaded end of the container snapping past the bead of the cap flange when the cap is applied to the container and outwardly flexing the wall of the cap flange above the beaded edge thereof to form a seat for the beaded end of the container above the outwardly directed head of the cap and provide resistance against removal 'of the cap.
2. In combination with a container having an outwardly directed bead around its normally open end, a paper closure cap, said cap including a top portion and a depending flexible expansible flange having an outwardly directed bead formed around its bottom edge, the flange being normally free of substantial indentations or protrusions between the top portion and bead, said bead projecting outwardly beyond the plane of the top portion of the cap and the other part of the flange, and the diameter 01' the beaded end of the container being greater than the interior diameter of the closure cap flange, the beaded end of the container snapping past the bead of the cap flange when the cap is applied to the container and outwardly flexing the wall 01' the cap flange above the beaded edge thereof to form a seat for the beaded end of the container and provide resistance against removal of the cap.
3. In combination with a container having an outwardly directed bead around its normally open end, a paper closure cap, said cap including a top portion and a depending outwardly inclined flexible expansible flange having an outwardly directed bead formed around its bottom edge, the flange being normally free of substantia1 indentations or protrusions between the top portion and bead, and the dia'meter of the beaded end of the container being greater than the interior diameter of the closure cap flange, the beaded end of the container snapping past the bead of the cap flange when the cap is applied to the container and outwardly flexing the wall of the cap flange above the beaded edge thereof to form a seat for the beaded end of the container and provide resistance against removal of the cap.
4. In combination with a container having an outwardly directed head around its normally open end, a paper closure cap, saidcap including a top portion and a depending outwardly inclined flexible pleated flange having an outwardly directed bead formed around its bottom edge, the flange being normally tree of substantial indentations or protrusions between the top portion and bead, and the diameter of the beaded end of the container being greater than the interior diameter of the closure cap flange, the beaded end of the container snapping past the bead of the cap flange when the cap is applied to the container and outwardly flexing the wall of the cap flange above the beaded edge thereof to provide resistance against removal of the cap.
