FRY-OFF COVER CONTAINER Filed March 12, 1925 I 4 I a i 2w 1 ;1/// Y :TYIIIIIIIIIIII my Patentedoct. 19, 1926.





- Application filed March 12, 1923. Serial No. 624,320.

The present invention relates to an-improved construction of containers'of the slip cover variety, which construction is adapted to facilitate the removal'of the cover.

Aprimary object of the invention is the provision pf a slip cover container which may be readily opened by means of any available instrument, or by means of a coin, it being thus unnecessary to provide any special opening device and the opening Operation being facilitated under? all con- -ditions.

The ordinary method of packing lard in containers to render them suitable for shipment to consumers consists in placing the lard in containers in a melted condition, then hermetically sealing a thin cover on the .container'and over this placing a slip cover for-use after the container is opened.

It has heretofore been impossible to make an outside friction fit slip cover sufliciently tight to hold the lard during transportation and storage without the inner hermetically sealed cover. pail of lard packed in this kind of a con- .tainer the first operation is tocut out the sealed-in cover and to use the slip cover as a closure during the time the lard isbeing used from thecontainers. This procedure 'necessitatedtw'o covers to the can and priorto my invention disclosed herein was the only practical method of packing lard in containers of this type that would hold the contents until they reached the consumer. I 7

. My invention provides a closure that is I sufliciently tight through its frictional contact to hold lard and permit of shipment and r storage and entirely eliminates thehermetill sealed cover that has heretofore been ap lied to lard pails.

11 order to make the friction closure sufficiently tight to perform this function it was necessary to make it as shown in my drawings herewith and to provide. some means of prying the cover off of the can other than just the fingers of the consumer whiclris all that has. been necessary with the "OI 'dlDEI'yslip eoven;

Another importantfeature of the invention resides in providing shielding means for protecting the edge of the cover in my invention and prevent adjacent pails'in a car-' ton or box from rubbing against each other. and dislodging the This shielding:

When the consumer gets a means performs a double function. It comprises an out-turned bead located and spaced a slight distance below the lower beaded edge of the cover when the cover is placed home on the pail. If this head were not present the beads of adjacent covers would come in contact and some of the covers might be dislodged during" the constant shaking given the packages during transportation. The thickness lief this bead is. greater than the distance from it to the bead of the lower edge of the cover so that the beads on adjacent packages may not enter the space betweenthe bead of the lower edge of the covers. Inasmuch as it is necessary to make a very tight friction closure some means must be provided for opening the closure. This may be accomplished through using a. screw driver, end of a spoon handle, or any other flat implement that may be at hand and prying the cover-01f of its seat by using the upper, surface of the bead as an abutment. I v

In shipping lard in a friction closed con tainer it is very essential that covers re main in place because during thesummer months the insides of cars transporting prodnets of this kind become quite hot, sufliciently so to render the lard more or less liquid andifthecovers are not liquid tight and the cartons happen to be packed so that the containersinside are upside down,

the melted lard will seep out and produce short weight packages besides mussing up the outsides of the containersfin the'carton, and if a covershould be dislodged so that the entire contentsof a package should leak out, it would spoil the appearance of the whole shipment.

i The combined friction of the cover on the outside of the pail and around within the bead is necessary in order to properly hold the coverin place under the conditions described and since this improved lard pail is displacing the other type mentioned; it.

is sufiicient. evidence thatit is the first succe'ssful friction closed lard pail produced.

Other objects and advantages of the in:v

vention will be apparent as it is better understood from the following description,

-which, taken in connection with the accompanying drawings discloses a preferred embodiment thereof, a

Referring to the drawings, Figure 1 is aside elevation of a container of the upper portion ofthe container, with the cover shown in spaced relationship.

The invention as illustrated in the drawings is embodied in a container of the lard pail type, in which the body 11 is of tapered form and is closed by means of a slip cover 12 frictionally fitting upon the upper end thereof. Said body is closed at the bottom by means of an end 13 attached in any desired manner. A bail, or handle 14 is secured at its ends in bail ears 15 projecting from the sides of the body.

An outwardly extending bead 16'is formed in the upper part of the body 11 and preferably is of considerable width, for a purpose which will hereinafter appear. A channel, or depression, 17 is formed in the. body material above the head '16. The cover 12 has :1, depending flange 18 which is curled at its lower edge, as indicated at 19, and when this cover is in place, the curled edge 19 is disposed opposite the mouth of the channel 17. It will be apparent that an instrument may be inserted in the channel 17 beneath the curled edge 19 of the cover and fulcrumed upon the bead 16, which provides adequate leverage for removal of the cover.

The upper edge of the body is curled, as shown at 21, and the cover is formed with an inwardly extending wall part 22, which,

' with the flange 18,4Eorms a channel in which said curled edge 21 of the body is disposed. Thus, when the cover is pressed down, a tight closure is provided and the curled edge 19 of the flange is spaced from the bead, or shoulder, 16 a suiiicient' distance to permit insertion of the opening instrument in a space'23 between said bead and cover edge. t

It is thought that the invention and many of its attendant advantages will be understood from the foregoing description, and it will be apparent that various changes may be made in the form, construction and arrangement of the parts without departing from the spirit and scope of the invention, or sacrificing all of its material advantages, the form hereinbefore described being merely a preferred embodiment thereof.

I claim: v

A container, comprising a body provided with a projection on the upper part thereof and a depression above said projection extending entirely around the container, and an outstanding and upwardly extended cylindrical part above and of greater diameter than said depression, and a slip cover adapted to engage said'cylindrical part of said body and having an outwardly extending curled edge disposed opposite said depression, so that the covermay be removed by applying a tool in the depression and under the curled edge at any point in the circumference of the can.
