Application med mum a, 1928. Serial No. 245,290.

This invention relates to can covers of the kind commonly known as the channel and friction plug type, wherein thetop of the can is fitted with an interior rim, 1n which 5 is formed a downwardly projecting circularnel, whereby the objects of the invention are attained.

An object is to provide, with practically no additional expense in the manufacture of the can, drainage holes in the channel whereby the liquid contents, for example paint, if dropped or spilled in the channel, as nearly always occurs in the ordinary use of a paint brush, will be drained back into the can. By wiping a brush around in thechannel the remaining liquid can be pushed down through the drainage openings. The channel is thus cleared of all material which might otherwise harden and cake in the channel. If paint is allowed to remain in the channel and harden it is impossible to properly put the cover in place again. My improvement avoids this, difliculty- A further object is to facilitate removal of the cover after the groove has once been coated with the material, by preventing suction binding between the head of the cover and the channel of the can. The holes in the bottom of the channel 40 which comprise my improvement permit air to enter the channel from within the can.

view of the upper part of a can and cover,

embodying my improvement. to Fig. 2 is a sectional view of the top rim of the can, showing the openings in the bottom of the channel. p

Fig. 3 is a partsectional bottom view of the parts shown in Fig. 2.

In the .drawings numeral 1 indicates the a can and 2 is the usual internal flange at the top of the can formed with the peripheral channel 3. 4 is the can cover formed with a downwardly projecting bead 5, the cover itself being of the kind commonly known as the friction-plug type of can top.

My invention consists in forming openings 6 in the walls of the channel, preferably at its bottom. Theopenings may be of any desired shape, although I prefer to make them in the form of elongated slots, as shown, for that form more readily permits the paint or other material to be wiped down through the groove by the simple circular wiping action of the paint brush.

The slots may be formed in any suitable way, for example, by slitting the metal and, bending the edges to form downwardly projecting lips 6 that will not cut the wiping brush 7 I have found in practice that this simple improvement eliminates the liability of the paint or other material caking and filling the channel 3. Consequently it enables the cover to be taken off and put back repeatedly while preserving the accuracy of its fit in the channel 3 and consequently the tightness of the can Having thus described my invention, what I claim and desire to secure by Letters Patent is:

1. In combination, a plug-type can cover, a can having an internal flange presenting a circumferential channel arranged to receive the lug element of said cover, the wall of said channel formed in its bottom with drainage openings for clearing said channel of the contents thereof and for access of air from the can to the channel during removal of said cover.

2. A structure as set forth in claim 1 wherein the metal at the edges of said drainage openings is bent to form downwardly projecting lips.

3'. In a can having a circular groove 5 margins, said lips spaced apart to present formed in its rim and a coperat' plugt e cover, the bottom of the rim iormed with elongated slots having downwardly projecting lips along their longitudinal a space into which fluid contained in the groove will be drawn b film tension.
