Abstract

A disc for mounting a valve onto a spray can which is capable of engaging a standard-sized protective cap such that the cap fills all the space between the disc and the top of the spray can regardless of variations in the thickness of the disc or the seal. The disc has a central body portion and an annular groove disposed at the periphery of the central body portion. The bead of the spray can sits within the annular groove. A seal is positioned between the annular groove and the bead. A spacer is positioned in the annular groove such that the spacial relationship between the bead and the annular groove is predetermined, i.e., the distance between the annular groove and the top of the can is a predetermined distance. Consequently, a standard-sized protective cap can be used for spray cans in which the seal thickness and disc thickness vary, wherein the cap fits snugly on the disc and fills the entire space between the disc and the top of the can.
