Claim 3

An easy opening container comprising: a container component having a surface; a one-piece essentially flat tab means having a first position flatwise against said surface and having an opening at one end and a bendable hinge at the other end including a portion permanently connected at one side to said surface, said hinge portion operative in said first position of the tab to hold the tab in said first position; a closure on said component displaceable into the container to provide a pour aperture through said surface; said tab bendable about the hinge from said first position to a second position disposing said one end thereof in overlying relation to said closure, said one end having means thereon for forcing said closure inwardly of the container and aligning said opening with said aperture upon said tab being pressed against said closure.

Claim 4

An easy opening container comprising: a container component having a surface; a one-piece essentially flat tab means having a first position flatwise against said surface and having an opening at one end and a bendable hinge at the other end including a portion permanently connected at one side to said surface, said hinge portion operative in said first position of the tab to hold the tab in said first position; a closure on said component displaceable into the container to provide a pour aperture through said surface; said tab bendable about the hinge from said first position to a second position disposing said one end thereof in overlying relation to said closure, said one end having means thereon for forcing said closure inwardly of the container and aligning said opening with said aperture upon said tab being pressed against said closure.

Claim 5

The invention according to claim 2 and said tab and container component having cooperative means operative to secure the tab to said container in said first position and to vent the container in response to said bending of said hinge.

Claim 6

The invention according to claim 3 and said venting means comprising a vent hole through said surface, and a plug in said vent hole connected to said tab and withdrawable from said hole during said swinging movement of the tab.

Claim 7

The invention according to claim 2 and said forcing means comprising a projection on said tab adapted to fit into said aperture.

Claim 8

The invention according to claim 5 and said projection encompassing the opening on the tab and dimensioned to fit into said aperture and provide a shield about said aperture.

Claim 9

The invention according to claim 6 and said projection having a groove adapted to receive therein a wall portion of said component.

Claim 10

An easy opening container comprising a body with an end panel having a closure flap displaceable into said container to form a pour aperture therein, a one piece generally flat tab located in a first position biasing said tab to said first position at one side of said aperture against said panel and having first and second end portions and an intermediate bendable hinge portion, means securing said first portion to said panel adjacent to the aperture, said second portion being liftable and having an opening therein, said liftable second portion adapted to be swung 180* with attendant bending of the hinge portion to a position disposing said second portion in overlying relation to said closure flap, said second portion having means for depressing said flap into the container upon pressure being applied thereto.

Claim 11

An easy opening container comprising a body with an end panel having a closure flap displaceable into said container to form a pour aperture therein, a one piece generally flat tab located in a first position biasing said tab to said first position at one side of said aperture against said panel and having first and second end portions and an intermediate bendable hinge portion, means securing said first portion to said panel adjacent to the aperture, said second portion being liftable and having an opening therein, said liftable second portion adapted to be swung 180* with attendant bending of the hinge portion to a position disposing said second portion in overlying relation to said closure flap, said second portion having means for depressing said flap into the container upon pressure being applied thereto.

Claim 12

The invention according to claim 8 and said tab having an obverse side facing said panel and said depressing means being formed on the reverse side of the tab whereby upon the tab swinging about said hinge portion said depressing means is disposed between the tab and the closure flap.

Claim 13

The invention according to claim 9 and said depressing means comprising a projection complementally shaped to the pour aperture for close fitment therein.

Claim 14

The invention according to claim 10 and said projection being flexible and comprising a peripheral groove adapted to receive the marginal edge portion of the pour aperture.

Claim 15

An easy opening container comprising a body with an end panel having a closure flap displaceable into said container to form a pour aperture therein, a tab located at one side of said aperture and having a bendable hinge portion fixedly secured to said panel adjacent to the aperture, said tab having a liftable portion with an opening therein, said liftable portion adapted to be swung 180* with attendant bending of the hinge portion to a position overlying said closure flap and having means for depressing said flap into the container upon pressure being applied to said tab, and vent-forming means connected to said hinge portion operable to form a vent in the end panel attendant to bending of the hinge portion upon lifting of the tab.

Claim 16

An easy opening container comprising a body with an end panel having a closure flap displaceable into said container to form a pour aperture therein, a tab located at one side of said aperture and having a bendable hinge portion fixedly secured to said panel adjacent to the aperture, said tab having a liftable portion with an opening therein, said liftable portion adapted to be swung 180* with attendant bending of the hinge portion to a position overlying said closure flap and having means for depressing said flap into the container upon pressure being applied to said tab, and vent-forming means connected to said hinge portion operable to form a vent in the end panel attendant to bending of the hinge portion upon lifting of the tab.

Claim 17

The invention according to claim 12 and said vent forming means being in the form of a rivet extending through and closing an opening in the end panel.
