Easy open container end assembly

A container end assembly comprising:

• a container end of flexible sheet material which takes a permanent set when substantially folded, said container end having a generally U-shaped cut defining three sides of an openable aperture in the container end assembly and including a necked tongue-like portion projecting between the sides and toward the base of the U-shaped cut, said container end having a through opening defined by said U-shaped cut and said tongue-like portion;
• and
• a tape adhered to the exterior surface of the container end circumjacent and completely covering said U-shaped cut, the end of said tape adjacent the base of the U-shaped cut being unadhered and having a tab adapted for manual engagement;
• said tape being peelable from over the U-shaped cut to open the aperture by manually pulling the tab over the tape, the distal end part of the tongue-like portion causing it to remain adhered to the tape and the neck part of the tongue-like portion permitting the tongue-like portion to bend back with the tape during such peeling, the bent tongue-like portion taking a permanent set to hold the peeled tape closely adjacent the container end, and adhesion in shear between the tape and bent tongue-like portion restricting separation of the tape from the container end.

• and
• a sheet adhered to the interior surface of the container end circumjacent and completely covering said U-shaped cut with portions of the sheet around the tongue-like portion adhered to the adjacent surface of the tape through said opening, said sheet being adapted to separate along said U-shaped cut as said tape is peeled away;
• adhesion of the distal end part of the tongue-like portion to the tape and the portion of said sheet remaining on said tape and over said tongue-like portion when the tape is peeled away attaching the distal end part of the tongue-like portion to the tape and the neck part of the tongue-like portion permitting the tongue-like portion to bend back with the tape during such peeling, the bent tongue-like portion taking a permanent set to hold the peeled tape closely adjacent the container end, and adhesion in shear between the tape and bent tongue-like portion restricting separation of the tape from the container end.

A can end assembly comprising:

• a can end of flexible sheet metal which takes a permanent set when substantially folded, said can end having a generally U-shaped cut defining three sides of an openable aperture in the can end assembly and including a necked tongue-like portion projecting between the sides and toward the base of the U-shaped cut, said container end having a through opening defined by said U-shaped cut and said tongue-like portion;
• a tape adhered to the exterior surface of the can end circumjacent and completely covering said U-shaped cut, the end of said tape adjacent the base of the U-shaped cut being unadhered and having a tab adapted for manual engagement, said tape being peelable from over the U-shaped cut to open the aperture by manually pulling the tab over the tape;
• and
• a sheet adhered to the interior surface of the can end circumjacent and completely covering said U-shaped cut with portions of the sheet around the tongue-like portion adhered to the adjacent surface of the tape through said opening, said sheet being adapted to separate along said U-shaped cut as said tape is peeled away;
• adhesion of the distal end part of the tongue-like portion to the tape and the portion of said sheet remaining on said tape and over said tongue-like portion when the tape is peeled away attaching the distal end part of the tongue-like portion to the tape and the neck part of the tongue-like portion permitting the tongue-like portion to bend back with the tape during such peeling, the bent tongue-like portion taking a permanent set to hold the peeled tape closely adjacent the container end, and adhesion in shear between the tape and bent tongue-like portion restricting separation of the tape from the can end.

A container end assembly comprising:

• a container end of flexible sheet material which takes a permanent set when substantially folded, said container end having a cut defining three sides of an openable aperture in the container end assembly and including a tongue-like portion projecting between opposite sides of the cut, said container end having a through opening defined by said cut and said tongue-like portion;
• a tape adhered to the exterior surface of the container end circumjacent and completely covering said cut, the end of said tape toward which said tongue-like portion projects being unadhered and having a tab adapted for manual engagement, said tape being peelable from over the cut by manually pulling the tab over the tape;
• and
• means for attaching the distal end part of the tongue-like portion to the tape to cause the distal end part to remain attached to the tape and for affording bending of the part of the tongue-like portion between its distal end part and its proximal end back with the tape during such peeling, the bent tongue-like portion taking a permanent set to hold the peeled tape closely adjacent the container end, and adhesion in shear between the tape and bent tongue-like portion restricting separation of the tape from the container end.
