<p>A dispensing package includes a container (26) having a neck finish (24) with an axis, a non-circular cross section in a plane perpendicular to the axis, and at least one circurnf erentially extending external engagement element (30) on the neck finish. A closure (22) has a wall (42) received over the container neck finish. The wall has a non-circular cross section corresponding to the non-circular cross section of the neck finish and at least one internal circumferentially extending engagement element (44) in engagement with the external engagement element on the neck finish. The internal circumferentially extending engagement element and/or the external circumferentially extending engagement element has a shallow lead- in angle (32) to enable press-fit of the closure onto the container neck finish and a steep back angle (34) to retard removal of the closure from the neck finish. Rotation of the closure on the neck finish is prevented by the non-circular cross sections of the neck finish and the closure wall.</p> |
