ABSTRACT:
An assembly for securing and sealing a dispenser, such as a pump or valve, to a flanged container is disclosed. The assembly comprises a mounting cup having a generally cylindrical skirt around its periphery and a sealing collar including a sleeve having a diameter sized to receive the sidewall of the flange and sized to be encased by the mounting cup. The end portion of the sleeve, preferably a plurality of spaced tabs, is in the path of movement of the mounting cup and is deformed radially inwardly beneath the flange ledge thereby to secure the collar to the flange.
