Application filed February at, 1928. Serial No. 258,781.

This invention relates to new and useful improvements in can opening-devices, and has particular reference to that character of device, directly associated with the can, so that the lid can be readily removed therefrom, without employing any implements forei to the can structure.

urther the invention has to do with an opening means for that character of can equipped with a slip ty e lid and wherein the manu acturers identig rim of the lid, necessitating the tearing of the label ofi of the can or at least the ripping of the label circumferentially beneath the edge of the said lid rim. This is a very tedious proposition and frequentl requires a considerable amount of time. y particular invention is of such a nature as to permit 7 ofthe' easy and rapid ripping of the label directly beneath the lid rim after which the lid may be quickl raised from the can body.

An important 0 ject of this invention is the provision of a can opening device of th1s character that is extremely simple in con- .my improved opening device.

Figure 2 is a similar view opemng device 'as having been primarily manipulated to cause the tearing of a portion of the label, after which the label may be severed circumferentially beneath the rim of the clamp lid.

Figure 3 is a fragmentary perspective of the upper end of the can disclosing the opening device havin been manipulated to partially sever the la el.

Figure 4 is a fragmenta vertical section through the upper end of t e can disclosing the opening device as having been primarily manipulated as disclosed in Figure 2.

Figure 5 is a bottom plan view of the can lid equipped with the opening device disclosing and advertising label is pasted around the can and around the disclosing the ing the opening device in its association with the lid, prior to the application of the can label to the lid and can body.

Figure 6 is ,a perspective of the opening member.

Figure 7 is a plan view of the blank from which the member is formed. 7

Figure 8 is an enlarged transverse section take substantially on the line 88 of Figure Now having particular reference to the drawings, there is disclosed a cylindrical can A of reduced diameter at its upper end adapted to receive the rim of the usual slip type lid B. As'is usual, after the lid has been disposed upon the can body, the manufacturers identifying and advertising label C is pasted upon the body A and around the rim of the lid B for securing the lid to said can body.

My invention consists of a tongue of predetermined length of tin or other ductile material5, that is pivoted at its inner end to the center of the lid B, at the under side thereof as indicated by the reference character 6. From this pivot point, the tongue extends radially outward and is bent slightly downwardly until it passes over and clears the upper end of the body. It is then carriedvertically downward between the reduced upper end portion of the body' and the inner side ofthe lid rim after which it is carried radially outward below the edge of the lid rim. From this it follows that the tongue is provided with a vertical portion 7, having close engagement between the reduced body end and the inner side of the lid rim, and

from the lower end of said portion 7 the tongue is bent directly outwardly at right angles providing a tab 8. That portion of the said tongue member beneath the rim of the lid B is preferably narrower than the tongue 8, while one edge of this narrow portion is sharpened to providea cutting edge 9.

The bending I in curved manner downwardly of the tongue 5 fromthe pivot point 6 to where the tongue clears the upper end of the body and extends downwardly between the body end and the lid rim is materially advantageous because it averts friction and binding tendency between the tongue 5 and the corner of the lid B and in that way assures easy movement of the tongue 5 when it is moved about the pivot point 6 even if the pivot point 6 is slightly off center.

After the lid B has been arranged upon llt) the can body A, the tab 8 is bent upwardly into engagement with the outer surface of the lid rim as disclosed in Figure 1, after which the label 0 is applied to the can body and to the rim of the lid for securing the lid in position.

Obviously, when it is desired to remove the lid from the can, the tab 8 which projects slightly above the upper edge of the label C is pulled downwardly into the position disclosed in Figure 4, thus tearing a portion of the label at the upper end thereof as also disclosed in Figures 2 and 4. The tongue 5 is then moved around the can as disclosed in Figure 3, for obviously forcing the knife edge 9 through the label C, directly beneath the rim of the can lid B.

After the label has been completely severed beneath the rim of the lid B, an upward pulling upon the tab 8 of the tongue 5 will cause the removal of the lid from the can body,

lit will thus be seen that l have provided a highly novel, simple and inexpensive opening device for a particular character of can structure, and while the invention resides specifically in a particular shaped or designed momma riping tongue for pivotal association at one end with the center of the can lid, it is nevertheless to be understood that some changes may be made therein Without affecting the spirit and scope of the appended claim.

Having thus described my invention, what I claim as new is:

The combination of a can including a body and a slip type lid with a rim thereon, a readily-severed label mounted on and surrounding the body and the rim of the lid for securing the lid to the body, a tongue pivoted at its inner end to the central port-ion of the interior of the lid and curved downwardly to space it from the top and corner of the lid and extending radially from said point of connection to a point above and spaced from the upper end of the body, said-tongue for an intermediate portion of its length being bent vertically downwardly and arranged within the rim of the lid and between said rim and the end portion of the body and terminating at its outer end in a tongue disposed exteriorly of the body and lid.

lln testimony whereof I aiiix my signature.
