This invention relates to a medicinal applica
tor and dispenser, and has for its objects an
improved device for applying a medicine in the
form of a liquid or jelly, to internal body cavi
ties for disinfecting such cavities and‘ which de
vice is ?exible and elastic and is provided with
a-socket for ?tting over any suitable, relatively
rigid projecture, for supporting the same in the
4-, connected at its edges. at 5 adjacent the junc
desired body cavity during manipulation thereof,
and which device also is formed with a supply
chamber adapted to contain a supply of such
liquid or jelly or the like,that communicates with
a delivery or dispensing chamber, for supplying
the contents of the supply chamber to the dis
ture between wall 3v and walls I‘.

cap and end wall. Adjacent the connection 5
between the cap and socket member I, are one or
more discharge apertures 1 that open generally
radially outwardly of the central axis of the
socket member 11. Preferably several of these
openings are provided’ at equally spaced points
around the margin ‘of cap 4.
