M invention relates to containers. It is vided with a lurality of radial slots which particularly applicable to that type of conextend inwar ly from the free edge thereof tainer which is made of fiber board or simibut which terminate short of the line of lar material.

This integral iiange is provertical wali of the container to form a nonma tubular body portion and superimposed upon the non-slotted shelf 4 and the tabs 5 of the annular flange 2. The disk is of such diameter that it closely lits the internal wall of the tubular portion and is mainly supported by the non-slotted shelf portion 4, with such laterally support as is supported by the vertical inner wall of the body portion.

The bottom of the container is further provided with an exterior disk 7 that is of somewhat thinner material. T his disk 7 is preferably connected to the tabs 5 and to the disk 6 by means of adhesive. Furthermore, the disks 6 and 7 and the tabs 5 are secured together by means rof a plurality of stitches 8 which lare preferably formed of flat metal tape. One of these stitches is provided for each tab and extends transversely thereof so nas to offer the simultaneous resista-nce of its legs to any strain which might tend to break the bottom out of the container or cause other breakage therein.

The structure of the top of my container is substantially identical in form with the bottom structure thereof. It will also be understood that this top may be secured to the body portionpof the container in any suitable manner. As shown in the drawings a plurality of stitches 9 can be used extending through the side walls of the top and the body portion 1, or metal strapping for wiring placed around package; one or'more ties to be used as found necessary for the service required.

It will be seen from this description that I have provided av container which may be made of fiber board, pulp board, paper' or straw board and which is so formed that the chime thereof presents unusual elements of stren h. Furthermore, this result is accomp ished without complication of the structure and, in fact, by extremely simple means. The disk 6 and also the correspond- 1ng disk in the top of the container are malnly supported directly upon the integral wall formation of the tubular body portion, that is, upon the non-slotted shelf portion 4 instead of upon the comparatively weaker -tabs 5. Furthermore, this interior disk in the top structure is further supported directly u pon the upper wall of the tubular body portion as at 10, whichgives an added element of stren h at this chime. In addition, the provision of individual stitches extending transversely of the tabs further strengthens the structure and is supplemented by the connection of the disks to each other and to the tabs by adhesion.

Having thus described my invention what I claim is:

1. A container end structure made of ber board or similar material comprising a cylindrical body portion, an inwardly extending" integral annular flange on one end thereof comprising an unbroken shelf and a series of tabs of maximum width disposed in the same plane, a disk of fiber board or similar material within said body portion and having a vertical support from said inwardly extending annular flange and a lateral support from the vertical inner wall of said body portion, and means for securing said disk and said annular flange together.

2. A container end structure made of fiber board or similar material tornprisingI .a cylindrical body portion, an inwardly extending annular iange on one end thereof forming an unbroken shelf and. having a plurality of radial slots formed therein to produce a series of tabs of maximum width disposed in the same plane, a disk of fiber board or similar material within said body portion and having a vertical support from said inwardly extending annular fiange and a lateral support from the vertical inner wall of said body portion, and means for securing said disk and said annular flange together.

3. A container structure made of liber board or similar material comprising a cylindrical body portion, an vinwardly extending annular flange on one end thereof forming an unbroken shelf and-having a plurality of radial slots formed therein to produce a series of tabs of maximum width disposed inthe same plane, a disk of fiber board or similar material within said body portion and having a vertical support from said inwardly extending annular flange and a lateral support from the vertical inner wall of said body portion, means for securing said disk and said annular iange together, and a closure of like structure which fits over the upper end of said body portion and has its base in direct contact therewith.

4. A container end structure made of fiber board or similar material comprising a cylindrical body portion, an inwardly extending annular iiange on one end thereof and having 7 of said annular fiange and the joint of such` annular flange with said c lin'drical body portion, a disk of fiber boar or similar material within said body portion, said disk being comparatively rigid and .having a vertical support from the annular shelf of said annular ange and a lateral support from the vertical inner wall of saidbody portion, a disk on the outside of said annular dan e, and securin staples for securing both o said disks an said annular flange to ther, the staples extending transversel o the tabs which form a art of said annu ar flan n testimony whereof hereby aix 'my signature.
