Abstract

A can end provided with an opening and a can end sealing portion. A slide is disposed against the can end adjacent the opening, and is provided with a first pour opening. A stationary member is disposed against the slide and is provided with a second pour opening and a stationary member sealing portion. The slide has a slide sealing portion adjacent the second pour opening and is movable to a sealing position where the first pour opening does not overlap the second pour opening. A pull tab has a connection to the slide. Engaging means engage the can end and one of the slide and the stationary member to position the stationary member sealing portion adjacent the can end sealing portion, and to press the slide against the stationary member adjacent the second pour opening. A pressure barrier material is used for sealing the can end sealing portion to the stationary member sealing portion and the slide sealing portion to the stationary member adjacent the second pour opening. The pressure barrier material is bonded to the stationary member adjacent the second pour opening with a first predetermined shear strength and to the slide sealing portion with a second predetermined shear strength less than the first predetermined shear strength. The pull tab is movable to cause the slide to move away from the sealing position to break the bond between the slide sealing portion and the pressure barrier material adjacent the second pour opening. The pull tab then is movable to cause the first pour opening to overlap the second pour opening to uncover the second pour opening.

[5 7] ABSTRACT A can end provided with an opening and a can end sealing portion. A slide is disposed against the can end adjacent the opening, and is provided with a first pour opening. A stationary member is disposed against the slide and is provided with a second pour opening and a stationary member sealing portion. The slide has a slide sealing portion adjacent the second pour opening and is movable to a sealing position where the first pour opening does not overlap the second pour opening. A pull tab has a connection to the slide. Engaging means engage the can end and one of the slide and the stationary member to position the stationary member sealing portion adjacent the can end sealing portion, and to press the slide against the stationary member adjacent the second pour opening. A pressure barrier material is used for sealing the can end sealing portion to the stationary member sealing portion and the slide sealing portion to the stationary member adjacent the second pour opening. The pressure barrier material is bonded to the stationary member adjacent the second pour opening with a first predetermined shear strength and to the slide sealing portion with a second predetermined shear strength less than the first predetermined shear strength. The pull tab is movable to cause the slide to move away from the sealing position to break the bond between the slide sealing portion and the pressure barrier material adjacent the second pour opening. The pull tab then is movable to cause the first pour opening to overlap the second pour opening to uncover the second pour opening.
