Abstract:
1. An applicator for delivering a formulation into a user's mucosal cavity comprising: a hollow cylindrical body having an open proximal end, a partially closed distal end, and a cylindrical wall extending longitudinally therebetween; said cylindrical wall being provided with a plurality of peripheral holes disposed both along its periphery and a major portion of its length; an internal wall structure secured to said partially closed distal end of said hollow cylindrical body end so as to extend generally coaxially therein for a major portion of the length thereof substantially overlapping with the length of said hollow cylindrical body having said peripheral holes disposed thereon; and a piston for reciprocal movement in said hollow cylindrical body having a proximal end, an open distal end and including an internal abutting wall defining a reservoir in said hollow piston for complementary cooperation with said internal wall structure; whereby, in operation, pushing said piston including the formulation in its reservoir in said hollow cylindrical body causes the reservoir to receive said internal wall structure therein via said piston open distal end causing the formulation to exit the reservoir and to subsequently exit through said plurality of peripheral holes along the length of said cylindrical body and said partially closed distal end, yielding a uniform delivery of the formulation within the mucosal cavity of the user.
