1. A device comprising:
a first blow molded part having a first portion;
a second part including an outer section;
a sealing flange extending from the first portion towards a central axis of the first portion at a distance, an end of said sealing flange defining an opening;
said second part adapted to insert into the opening in an insertion direction and at least part of the outer section of the second part has a size larger than the opening and the outer section includes a tapered section;
said sealing flange flexing in the insertion direction upon insertion of said second part into said opening such that the end of said sealing flange moves inwardly in the insertion direction and a contact surface is defined between the outer section and the sealing flange such that the contact surface extends around a perimeter of the outer section where the sealing flange contacts the outer section;
the flexing of the sealing flange caused by contact between the contact surface and the tapered section; and
portions of the first blow molded part and the second part interact with each other, when the sealing flange flexes and the contact surface and the tapered section are in contact, to hold the first and second parts in an axial position relative to each other.
