1. A hermetically sealed, molded package suitable for dispensing a substance into a body cavity, said package comprising:
- an elongated container body terminating at one end in a unitary dispensing nozzle and in a squeezable hollow protuberance at the other end;
said nozzle defining a dispensing orifice occluded by a unitary closure at the distal end of the nozzle;
a frangible web sealingly connecting said closure to said nozzle around said dispensing orifice while permitting removal of said closure upon rupturing of said web; and
a seamless sleeve mounted on said container body about said nozzle and surrounding the dispensing orifice and at least the distal end of said nozzle but not said unitary closure;
said sleeve including a plurality of ribs circumferentially spaced about the interior of said sleeve and the distal end portion of said sleeve defining an aperture for dispensing of the package contents after said closure has been removed.
