摘要：An assembly for securing and sealing a dispenser to a flanged container isprovided. The assembly includes a sealing collet formed from a resilient deformablemolded polymeric material. The sealing collet has an outer surface having an outer

diameter, and also has a continuous downwardly extending skirt having a bottom portionthereof extending radially outwardly. The assembly also includes a retaining collarformed from a substantially rigid material, which has a sleeve about its periphery havingan inner surface with a diameter sized to encase the skirt of the sealing collet. Theretaining collar is slideable through a path of movement over the sealing collet to anassembled position. The sleeve deforms the bottom portion of the skirt radially inwardlyto a position under the flange as the retaining collar is slid to the assembled position inorder to maintain the sealing collet and the retaining collar in the assembled positionand to maintain the seal between the sealing collet and the flange. A plurality of annularsplines, grooves or a combination thereof are provided on inner surface of the sleeve,and are positioned to engage the outer surface of the sealing collet when the retainingcollar is in the assembled position. The splines or grooves are formed to such an extentthat they cause the outer surface of the sealing collet to deform therearound when theretaining collar is in the assembled position to enhance the maintenance of the retainingcollar on the sealing collet in the assembled position.
