corporation of New Jersey Application eptember 5, 1945;"Serial N.6145534 11 a 4 Clafinlsw (c1. 220- 43) I The present invention relates to containers for cans having opening devices for removing-reels; sure covers therefrom andhas particular reference to a prying lever" opener which isperma nentlyand loosely attached-to th'ecovers for prying actio'n between "a. cover: and its container at difierent places "around' the cover forprying it from the container. n

An" object of the inventionis the provision'of "a prying lever opener for. l a container wherein the opener is simple in constructionand economical to produce" and which maybe permanently ap pliedto a container reclosurein sucha manner that' it can be shifted around the'periphery of 'the reclosure forprying' action-"at difierent places While at the same time being disposed so that i t I will not interfere 'with stacking of" the containers where such stacking is desired'x Numerous otherobjects and advantages of the invention will be apparent: as it is be'tte'r under stood from the following descriptirm, which; tak '1-'- in' connection -with the" accompanying drawings; discloses a preferred embodiment thereofl Referring to the drawing- Figure l is a perspectiveview"of 'asealedeoii tainer' embodyingthe instaht ihveii-tidn 2' V Fig. 2 is anenlarged vertical"sectidnal view 'oi the upper portion of the container shdwn in Figi l, l withtparts shown 'in elevation; l

thus-set off an inverted 'U-shaped channel 21% which encloses the curled edge 18' and the *neck section 66 when the cover 22 is in place on -'the' cans- A sealing gasket' 29 of rubber comp'ound'or otheri suitable material is disposed in the channel 28'and thus'provides a hermetic seal-between the cover flange25 and the curled edge l8 oi the can. A. pry-offopening -lever:- 35"is provided for -pry' ingot. the cover 22"when-it is' desired-to open the can-r This lever is made-preferably'of heavy sheet metal-andis-permanently"andloosely attached to the outer: depending wall-"section 26- of the -'coverso it can be shifted around the peripheral edg'e of the cover to' any desired-place topry the cover loose. The "opening lever includes a relatively long *curved vertical side wall- 36 (Figs. 1, and. 4) which is -disposed =normally adjacent to and parallel with -the "edge curl '21 of the cover-22. One endzotthe lever is formed with a handle-on actuating I pad*- 31 which extends outwardly from and at'right' angles to'th'e upper-edge of the curvedwanes, i

The opposite ?end of the wall section 3B-is formed with an upwardlydisposedrounded-cam edge- 38w Intermediate the ends 'of the lever, closely-adjacentsthe cam end, :the curvedwall sec tion-36 is 'formed with a narrownlocking lug 39' (Figsu-Z and 4) which extends laterally and. in wardly-under the edge-rcurl orpry-ofiedge 2! of the icoverv 22 and then upwardly at right angles into-the space between-the outer depending wall sectionr2fi -of thecover and the uprightneck wall *1 section-EH5 of -th'ewcan; as bestushown in 'Figr l. The --upper inner end of I this-dug terminates 1 closely adjacent the gasket 29 in the channel 285' Cooperating 'Wit/hf the locking lug 39-to hold the pry-ofi-leveronthe cover is alateralwallor shelf section which extends inwardly from the upper [4. This curled edge l8 defines a dispensing openedgeot the leversidewall section -36=- Thislateral ing IQ for the container.

The dispensing opening I19 is sealed with areclosure cover'or cap 22. -'This reclosure cover is formed-with a= countersunk dome shaped panel 23 (Figs. 2, 4 and 5) theouterperi-pheral edgezibf which merges into an upright or upstanding annular inner friction wall section 24." This annular wall section frictionally engages against the i'nner' surface of the curled edge-t8 of the'container arid thus holds the cover in place when the cover is on 6017 wall section 4-2ex'tends substantially from theiac tuatingpad 3-1 rearwardly of the-leverandis' adapted- :to contact 'withthe top surface or the cover pry-off edge 21 "to supportthe lever and to hol'd' it in=its normal or inoperativepositionj as shown' ini Fig. 1. Near the cam en'd of the lever the lateral. wall: section 42 durves'or extends u wardl'y l and "terminates opposit'e i the locking lug 3B-in clo'se ,p'roximit'yito the outeri'surface of the dependingwallsection 260i the cover (Fig.4) 1 l 4 wall portion extending along one edge thereof for supporting the lever on the pry-off edge of said cover, said lateral wall portion terminating adjacent the outer surface of said depending outer wall of the cover, said lever adjacent its cam end having a locking lug extending beneath said cover pry-off edge and thence outwardly becover to different places. for prying the 'cover' loose. This prying action is readily effected at any desired place around the cover, by a mere lifting of the lever by its actuating pad 3], as best shown in Fig. 3.

This lifting action brings the cam edge 38 of the lever 35 into engagement against the countersunk panel I! of the top end member l2 and with this cam edge as a fulcrum the locking lug 39 engages against the bottom surface of the pryoif edge 21 of the cover and thus pries the cover loose with the continued lifting of the lever.

With such a construction of opening lever, the lever is disposed normally in an inoperative position in the space between the cover and the end seam of the can and is thus in an out-of-the way place where it is always ready for use and at the same time protected against injury. In this normal position the lever in no way interferes with stacking of the cans l I if such stacking is desired.

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 bein merely a preferred embodiment thereof.
