Abstract:
A generally planar pull tab suitable for affixing to an exterior of a wall of a boxed end openable container having one end closed by bonding together opposing faces of the wall material so as to form a seal closure to the container, or for affixing to a blank for use in the manufacture of such a container, and by which pull tab a force can be applied by a user to the seal of such a container carrying the pull tab to apply a transverse separating force to the seal closure of the container and thus cause separation of the seal to open the container and thus permit discharge of the contents of the container, characterized in that the pull tab comprises:a. a shank member extending longitudinally between a proximal end adapted to be grasped by a user and distal end adapted to be secured to a wall of the container or the blank, said shank member having two longitudinally extending edges thereto; b. at least two foot members by which the distal end of the shank member is adapted to be secured to the wall of the container or of the blank, said foot members extending transversely one from each of said longitudinal edges of the shank member to provide foot members extending substantially symmetrically from the distal end of the shank member, said foot members each having a proximal edge which extends from a point on the shank member intermediate the proximal and distal ends of the shank member; c. the angle &agr; included between the said proximal edge of the foot member and the longitudinal edge of the shank member at the point where the foot member joins the shank member being less than 90Â°, whereby the foot member has a portion which extends axially towards the proximal end of the shank member with respect to the said point; and d. said pull tab being made from a sheet material having a surface which can be fused with or otherwise adhered to the material of said container or blank.
