  • container means for containing and delivering a liquid, said container means having walls defining an internal cavity;

    sleeve means mounted in a wall of said container, said sleeve means having a pierceable member closing one end thereof;

    cup means for containing the second substance, said cup means being slideably positioned in said sleeve means, said cup means having an open end;

    pierceable plunger means slideably positioned within said open end of said cup means;

    collapsible cap means positioned over the other end of said sleeve means, and over said cup means; and

    hollow piercing means disposed between said pierceable plunger and said pierceable member;

    whereby as said cup means is urged toward said pierceable member by collapsing said cap means, said piercing means will pierce both said plunger means and said pierceable member, and said plunger means will be forced inwardly of said cup means so as to force said second material from said cup means through said hollow piercing means into said container means.
