My invention relates to improvements in paper cans, and more particularly has reference, and is illustrated in the accompanying drawing'in its application, to the cover of a paper can, whereby a tight seal is obtained while at the same time insuring easy application and removal of the cover.
Referring to said drawing, Fig. 1 illustrates upon an enlarged scale, a broken portion of the upper part of a can, partly in section, embodying an application of my invention, and Fig, 2, the upper part of the can in side elevation.
3 indicates the body of the can which may be spirally wound as shown, and 4 indicates the cover, the wall of which may be provided with annular depressions 5, B, and a vent hole I. The top of the cover comprises a disc 8, the margin 9 of which is curled within the top margin In of the wall of the cover as shown, and an annular recess ll formed in the disc between the wall 4 of the cover and the annular depression l2, providing a seating H for the top edge of the body of the can, while at the same time providing lines of wall contact around the can at two circumferential depressions and B from' 35 outside the wall of the cover snugly engagethe body of thecan' more tightly than would be practical if the line of contact were continuous throughout the depth of the cover wall, and the cover is thus more easily applied and removed 40 notwithstanding the tighter fit made possible by the reduced surface area in contact. At the 5 and 6, which provide three distinct lines of cir-' are same time the slightly enlarged diameter of the cover at the bottom as shown at l3 facilitates applying the same, and as air is compressed in the can during the application of the cover, it is, partly vented through the hole 1, until the annular rib 5 engages the body of the can, thus minimizing internal compression, and making easier and quicker application of the cover; Upon withdrawing the cover, the suction is released as soon' as therib 5 leaves the top of the can, air enter- 10 ing through the hole .1, thus also facilitating and quickening the withdrawal of the cover.
of course it will be understood that various modifications may be made in the construction and arrangement of parts without departing from the spirit of the invention as claimed.

In a paper container, an oversized paper cover with depending skirt having inwardly projecting circum'ferentially extending sealing portioiis frictionally engaging the wallof said container, and an exposed hole through said skirt between said portions, said hole being adapted to allow outside airto automatically enter said container before said cover is completely withdrawn therefrom 2. In a paper container, an oversized' paper cover with depending skirt having inwardly pro-' jecting circumferentially extending sealing pore tions frictionally engaging the wall of said container, and an exposed hole through said skirt between said portions, said hole being adapted to allow outside air to automatically enter said container before said cover is completely withdrawn therefrom, said cover comprising a disc and a separate ring-like skirt, the upper edge of said skirt curled over the margin of said disc, and a depression beneath said margin into which the. top of the body of said container is seated.
