Abstract
A tubular container and an applicator of the dropper type extended through one end thereof and spaced from the walls of the container; a sealing gland on the other end of the container; a sealing element in the middle of the inner portion of the gland tightly engaging the tip of the applicator thereby to seal the same; the applicator is press fit in the end of the container and has a stem provided with resiliently collapsible element such as a bulb; one component of the proposed mixture being inside the applicator and the other component of the mixture is between the outer container and the applicator properly separated until such time that the applicator is withdrawn to a distance equal to the depth of the sealing pocket thereby freeing the tip and permitting the pumping of the contents of the applicator into the component in the outer container whereupon the applicator is used for mixing the two components and after mixing them, the mixture can be sucked into the applicator and then suitably dispensed.
