Abstract
Abstract A container having a pull tab secured to a scored removable section. A pivot member tethers the removable section to the container top after the can is opened by pulling the tab. The removable section may be so constructed that it can be swung back over the opening and pressed back into place to reseal the container. An indicator may also be provided to show that the container has been opened and resealed. The pull tab may also be provided with a locking arrangement for releasably locking the pull tab to the container edge in either open or closed position. In some constructions, a second air vent opening may be provided and a single unitary pull tab member may open and close both openings simultaneously. This member is pivoted to the can top to tether it to the can but allow a pivotal action to open or close the openings. This form may also be provided with an indicator for showing the breaking of the seal.
