RECEPTACLE COVER Filed Nov. 12, 1941 INVENTOR. Andrew Oztarezz BY Patented Mar. 21, 1944 UNITED STATES eATEN OFFICE RECEPTACLE COVER Andrew Ottesen, New York, N. Y.

Application November 12, 1941, Serial No. 418,637

2 Claims. (01. 220-48) This invention relates to new and useful improvements in receptacle covers.

More particularly, the invention proposes a cover construction adapted to be opened with a prying tool such as a screw driver, the back of a spoon, etc.

More particularly, the invention proposes an improved construction which will prevent the prying tool from slipping during the prying operation. Several embodiments of the invention are proposed. In one form a construction is presented in which the point of the prying tool does the prying. In other forms, the prying is accomplished by portions of the prying tool which are inwards of its point.

Another object of the invention is the construction of an article as mentioned which is simple and durable and which may be manufactured and sold at a reasonable cost.

For further comprehension of this invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawing, and to the appended claims in which the various novel features of the invention are more particularly set forth.

In the accompanying drawing forming a material part of this disclosure:

Fig. 1 is a perspective view of a metal can provided with a cover constructed in accordance with this invention.

Fig. 2 is a plan view of Fig. 1.

Fig. 3 is a fragmentary enlarged vertical sectional view taken on the line 3-3 of Fig. 2.

Fig. 4 is a fragmentary sectional View similar to Fig. 3 but illustrating a modified construction.

In the form of the invention illustrated in Figs. 1-3 inclusive, the receptacle cover has an inwardly directed channel In having an outer wall I l which continues into a base wall [2 which continues into an inner wall l3. A score line I4 is arranged in conjunction with the channel ID in the vicinity of the junction of the inner wall I3 and the body of the cover. These are the essential parts of the improved cover. It is intended that the cover be engaged upon the top of a receptacle, such as the receptacle l5. This engagement may be accomplished in the usual way by the double seam [6. The receptacle cover may be provided with additional recessed portions such as the central recessed portion l! which is for the purpose of stiffening and reinforcing the cover.

The receptacle cover may be opened with a prying tool schematically indicated by reference numeral I8. This prying tool may be placed against the inner wall I3 and extended into the channel [0 against the outer wall II and against the score line M. The prying tool I8 may comprise a screw driver or the back end of a spoon or other similar implement. To open the cover the prying tool l8 must be pivoted in the direction indicated by the arrow B. The intermediate portion of the tool breaks open the cover at the score line H.

The channel H) in the particular form of the invention shown is of annular shape, that is,-it extends completely around the edge portion of cover which is circular. The walls forming the channel ii] are at right angles to each other. The score line H is located at the junction of the inner wall l3 with the body of the cover. When a portion of the score line H is pried open it is possible to insert the prying tool beneath a portion of the ripped open cover and then the ripped open part may be further forced upwards and torn out.

The outer wall H is formed with a means for securing a purchase for the end of the prying tool. This means comprises a bead 22 formed upon the outer wall H of the channel ID. The prying tool i8 is engaged beneath the bead 22 and is then pivoted in the direction of the arrow B to break open the score line l4. The bead 22 is of a size sufficiently great to prevent an overshotting of the prying tool l8 when pivoted in the direction of the arrow B to break open the score line I l.

Fig. 4 shows a modified form of the invention which is similar to the previous form, distinguishing merely in the fact that a plurality of beads or corrugated portions 22 are formed. upon the side wall ll of the channel Ill. In other respects this form of the invention is similar to the previous form.

While I have illustrated and described the preferred embodiments of my invention, it is to be understood that I do not limit myself to the precise constructions herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as defined in the appended claims.

Having thus described my invention, what I claim as new, and desire to secure by United States Letters Patent is:

1. In a receptacle cover, an inwardly directed channel having an outer wall continuing into a base wall which continues into an inner wall, and upwardly directed bead portion adjacent and continuing from the top of said inner wall, a score line in the bottom face of said head portion, and

means for securing a purchase for a prying tool at a point within said channel and opposed to said inner wall, whereby a prying tool may be purchased in said channel and engaged against said inner wall and fulcrumed to break said score line open, said means for securing a purchase for the prying tool comprising corrugations formed upon the outer wall of said channel.

2. In a receptacle cover, an inwardly directed channel having an outer wall continuing into a base wall which'continues into an inner wall, and

upwardly directed bead portion adjacent and continuing from the top of said inner wall, a score line in the bottom face of said bead portion, and

means for securing a purchase for a prying tool 10 nel and said channel being of annular shape.
