Abstract

A positive orientation container and closure combination is provided. The container includes at least one flange segment having a front and a back face. The container further includes a gap defined by the front face of one of the flange segments and the back face of one of the flange segments. The closure includes a plurality of collar segments. The closure includes at least one collar segment having an engagement face to establish a positive orientation of the closure at a predetermined position.

Claims

1. A method of assembling an orientation container and an unthreaded closure,

the container including an unthreaded neck defining an opening to the container, the neck having a circumference and at least one flange segment that (a) is defined thereon extending along a portion of the circumference, and that (b) includes a container orientation structure having a front face defining a starting point of one of the flange segments and a back face defining an ending point of one of the flange segments whereby said front face and back face define between them a gap that is open in opposite axial directions as well as radially,

the closure including a plurality of collar segments, at least one collar segment including (a) a distal edge, and (b) a radially inwardly extending bead located at the distal edge,

the closure having at least one collar segment that includes (a) an engagement end, and (b) an engagement face located on said engagement end,

the method comprising the steps of:

placing the closure on the container;

rotating the closure with respect to the container in an assembly direction;

positioning said collar segment engagement face in said gap and contacting the container orientation structure front face of the at least one flange segment of the container neck with said engagement face of the collar segment to orient the closure on the container; and

providing a downward force on the closure wherein the at least one flange segment of the container neck is contacted by said collar segment bead to deflect the collar segment radially outwardly so as to pass over the at least one flange segment of the container neck and wherein the collar segment subsequently returns radially inwardly so as to position the collar segment bead beneath the at least one flange segment of the container neck.

2. The method of claim 1 further comprising the step of contacting a closure displacing structure located at said collar segment engagement end with the container orientation structure and thereby temporarily displacing at least a portion of the closure axially outward relative to the container as the closure is rotated in the assembly direction.
