Abstract:
1. A positive orientation container and closure combination comprising: a container having an interior, an opening to the interior, and at least one circumferentially oriented flange segment that extends less than 360 degrees, has a starting end defined by a front face, and has a termination end defined by a back face; a gap defined by the front face of one of the flange segments and the back face of one of the flange segments, said front face of one of said flange segments extending to an axial outward end of the gap; and a closure cooperatively associated with the container for closing the opening, the closure comprising a base portion for engaging said container around said container opening and for being closed by a lid, said base portion having a unitary structure and having a plurality of axially extending collar segments which each has an engagement end, each said collar segment being a unitary part of said closure base portion, the closure having a closure orientation structure unitary with said base portion and comprising an engagement face on at least one of the closure collar segments at the engagement end for engaging the front face of one of the container flange segments to establish a positive orientation of the closure at a predetermined position of rotation relative to the container as the closure is rotated relative to the container in an assembly direction; and further including a closure displacing structure located at the engagement end on one of the collar segments and having a surface slanted relative to the axis of rotation of said closure to engage said flange segment front face at an angle at the axially outward end of the gap and thereby displace the closure axially outwardly relative to the container as the closure is rotated in the assembly direction to allow further rotation of the closure in the assembly direction.
