Abstract
ABSTRACT OF THE DISCLOSURE
A tape seal end closure for closing pour openings in the end panel of a container. The tape is of rectangular configuration applied to a round end panel and to cover all of the openings extends to an area proximate the circular peripheral seaming chuck guide groove in the end panel. The tape is provided with a ring pull which is folded over the tape and forms corners with the body portion of the tape at its lateral edges. These corners, when the body portion is positioned to adequately cover all of the pour openings in the end panel project over and encroach upon the chuck guide groove since the proximate edge of the body portion of the tape extends chordally with respect to the groove. Cutting off these corners develops notches which concentrate failure -promoting stresses causing the tape to tear and thus frustrating opening of the container. The invention solves the problem by providing novel dart folds in these corners which clear the groove and which unfold when the ring pull is lifted thereby developing the full strength of the tape.

Description
~1~3~7~9 ~ :
In devices utilizing tapes for closing the pour openings, the tape is usually secured by pressure sensitive adhesives. In closing pressured beverages such as beer or soft drinks, pressure sensitive tapes have not been successul and even heat sealed ~apes have more or less consistently failed. The problem at least partially resided in having a single opening defining the pour aperture which has to be "
placed close to the rim or seam of the can thus minimizing '~
the area to which the adhesive is appIied and concurrently .~ .-10 limiting the area of tape ~hich can be adhered since the tape ,' has to clear the' chuck guide groove. ~,,' '~
This invention is directed to a tape seal for the ,~
'~ pour opening of a container for pressurlzed beverages.
A general object of the lnvention is to provide ', ~, ,a novel' tape~having a rectangular body ~hich is applied '' '~diametrically across the top of the round end panel in closing relation to the pour aperture and which has a ring-pull portion '~
~;~ at one end folded over the body portion and wherein suff,icient '~
'~ suTface'areas of the end panel and body tape are-securely 20 ~ adhered particularly in the'location between the edge of ,the pour opening and the chuck guide~groove. '-' '~
~ ~ The lnvention contemplates providing a tape'of ;~
,,~ sufficient width'not only to cover the pour aperture comprising ''~, multiple selectively arranged holes to minimize pressure on the tape, but also to provide an extensive sealed sanitary ,~ area maintained free of contamination and providing a ring -~
pull end portion of adequate size to admit the inger of ,, .. :

~3~7~9 to increase its tensile as well as tear or shear strength and of adequate width to form a ring pull at one end of the same diametrical dimension as the width of the body, so that the tape may be easily fed through and fabricated in suitable tape making equipment.
The invention comprehends providing a wide rectangular tape which intermediate its lateral edges is secured to the end panel close to the chuck guide by a novel folding of the corners of the tape formed by the juncture of the body and ring pull end portion, the corners being folded away to a nonobstructing position and unfolding during opening of the ; tab to provide an uninterrupted full width of tape from end to end.

annular chuck guiding groove 6 and a chuck wall 7 which is double seamed at 8 with the upper edge of the can body. - !
The panel is provided with a pour aperture generally designated 10 including a plurality of geometrically arranged openings 11, 12 which extend from the peripheral edge 13 of the panel 5 inwardly.
A tape 15 of a metal foil and plastic such as polypro~
pylene is used as a closure for the openings. The specific -details of such closure are disclosed in Canadian Patent . "
Application 219,842, filed February 1975, and the disclosure therein is herein incorporated by reference.
Suffice lt to say that the tape is secured by an ' adhesive to the can top 17 as in the aforesaid application for patent.
The tape herein shown is of a laminate metal foil and ~-~
plastic and of substantial width and covers the area designated 19 (Figure 3) on the can top. The tape comprises a rectangular ~ ; body portion 20 and at one end has an integral finger-grip portion 21 which is folded over the body portion in a fold bend juncture 23 transverse to the longitudinal extent of the tab.
As best seen in Figure 2, the ends of the bend juncture ~` ' 23 form right angle corner portions 24, 24 shown (shown in `, phantom lines in Figure 2) which would normally project over and encroach upon the chuck guide groove.

of dart -folds 25, 25 tucking in the corner portions 24, 24 between the pull ring portion and the body portion of the tab.
Each dart -foLd has upper and lo~er triangular dart -sections 26, 27 which converge inwardly from the respective lateral edges 289 29 of the tape and these sections 26, 27 have a fold juncture 30 which merges into an apical point 31 which coincides with the bend line 32 of the juncture 23.
It will be noted that the corners 24, 24 at the bend line are folded so that the outer edges clear the guide groove and at these outer edges 33 are preferably 45 degrees to the ~
bend line and adjacent lateral edge of the body of the tape. ;
This angle, however, is not critical and may be of any magnitude which will clear the groove.
It will be observed from Figure 3 that~ upon the ring pull portion being lifted the dart folds will unfold and the ;
full width of the tape connects the ring panel portion with the body portion. ;~
The ring pull portion has~ a circular hem edge 35 and 20 ~ a center fingeradmittlng opening 36 which also has a hem edge ~ -37.
