FIG. 8 is a top plan view of an easy opening container of a further embodiment of safety overcap with the overcap shown in a position wherein the pull tab is held cated substantially normal to the tear strip 22 and pull tab 24 as shown in FIG. 1. The overcap 14 is restrained in this position by thespaced detents 29 seated in the complementary spaced depressions 30. In FIG. 1 as described above, the pull tab 24 is partially received within the recess 33 so that access thereto for tilting the latter is not possible. When it is desired to open the container 10, the overcap 14 is rotated to-the position shown in FIG. 2 wherein the slot 32 is axially aligned with the tear portion 22 andthe pull tab 24 so that access may be had thereto for tilting the pull tab 24 and removing the tear strip 22 in the normal manner;
The overcap coverpanel 116 is formed with a slot 132 which accommodates the tear portion 22 and the pull tab 24 when the overcap is turned so that the slot 132 is alignedwith the tear portion 22 and pull tab as shown in FIG. 5. in the normal non-use position, the pull tab 24 is'turned about'the rivet 23 to a position generally normal to the longitudinalaxis of the tear portion 22. The pull tab 24 is restrained in this position by a detent 130 which engages one side of the tab 24.
- The end of the pull tab 24 is accommodated within a recess 133 formed on the underside of the cover panel 116. The recess prevents access toithe pull tab for tilting the latter into a positionfor opening or removing the tear strip 22. 4 V
1 To open the container, the edge of the'pull tab 24 adjacent the detent 130 is lifted slightly so as to clear the v latter. The overcap 114 is thereafter rotated counter- 4 along one side thereof and extending downwardly for the full length of the flange 219 on the other side. The slits 231-231 form a flap 232 which may be of lesser thickness than the remainder of the cover panel-216 and is hinged about a reduced section 233 as shown. The flap 232 is sufficiently thin to accommodate the thickness of the pull ,tab 24 when it lies flush with the remainder of the upper surface of the cover panel 216.
Projecting from the outer end of the flap 232 a downwardly depending finger grip tab 234. Spaced inwardly from the finger grip tab 234 is a second flange 236 which co-acts with the tab 234 to releasably embrace the double seam 13. Removal of the flap 232 by tearing along the reduced section 233 provides a slot 237 through which the tear portion 22 and pull tab 24 are accessible. After removal or lifting of the flap 232,
, the tab 24 may be tilted upwardly so as to remove the clockwise in the direction of the arrow as shown in FIGS. 4 and 5. The pull tab 24 seated within the recess is caused to turn about the rivet 23 to the position shown in FIG. 5 in alignment with the tear portion 22.
