DOUBLE GROOVE BEVERAGE CAN LID

Abstract: A beverage can lid (10) comprises an outer peripheral groove (11) adjacent the outer rim (21) and an inner concentric groove (12) separated therefrom by a dividing rim (13) which is at a predetermined height relative to the outer rim (21). A center platform (14) is connected to the dividing rim by walls (16), which slope downwardly from said rim. The central pull-tab area (17) is approximately the same height as the height of the inner groove (12) and is connected to the inner dividing rim (13) at one end with an upwardly curving surface (19). The outer groove (11) which may be shallow and permits entry of a crimping tool to mount the lid on a can is also easily cleaned to provide a sanitary can lid. The inner groove (12) may be blocked in the pouring spout area to facilitate cleaning.

Description: noi mi πn RΓV R AΓ.Γ r AN Ϊ in ΠFTAΪT rn r-Fsrwi TTO ΠF THF TNVFNTTOIV Referring now to the drawings, the invention compπses a sanitary beverage can lid 10 with double concentπc grooves 11 and 12 The outer penpheral groove 11 is separated from the inner groove 12 by a raised inner dividing πm 13 The outer groove 11 is located between outer nrri 21 and πm 13 A center platform 14 is connected to the inner dividing πm 13 by walls 16, which slope downwardly from said πm 13 The pull-tab area 17 is located centrally on the platform 14 and extends outwardly to the inner dividing πm 13 The pull-tab area 17 is at a height approximately that of the inner groove 12 and is connected to the πm 13 with an upwardly curved surface indicated at 19 The depth of the outer groove 11 can be lower, equal to or slightly higher than the depth of groove 12 The outer groove 11 can be shallow or deep but it still permits the cπmping chuck to press into groove 11 dunng assemb-v of the lid 10 to a can Preferably, groove 1 1 is shallow and may be easily cleaned with one's finger to eliminate any dirt or debris pπor to drinking Groove 12 is interrupted by walls 18, which block liquid from flowing into groove 12 Walls 18 can be lower, equal to or higher than πm 13 The lid design as proposed herein can be manufactured and assembled to cans with existing cπmping tools The cπmping tools, which affix the lid 10 to a can, may be used in connection wnh the double groove design The lid 10 is affixed to the can body as the cπmping tool engages groove 1 ] FIG 2 discloses a cross-sectional view taken along the line 2-2 in FIG 1 The drawing illustrates quite clearly that an individual is able to drink directly from the pull-tab area 17 without contacting a debπs-laden groov e l l In dnnking, one would place their lips against the raised πm 13 while for added measure the groove 11 may be easily cleaned in the vicinity of the pull-tab area 17 The mounting of lid 10 on the can may be accomplished with existing tools while the advantages of a sarutarv can lid are achieved by the double groove arrangement FIG 3 discloses an alternate embodiment of the invention wherein the inner groove 12 extends completely around the lid 10 The upwardly cur ed surface 19 connects the πm 13 to the pull-tab area 17 and compπses the drinking spout for the can, which may be readiK cleaned While the invention has been explained by a detailed descπption of certain specific
