Abstract:

An applicator 10 includes a barrel 12 for containing a semisolid medicinal, the barrel including a large diameter cylindrical section 16, a small diameter cylindrical section 18 and an annular sloped transition section 20 that connects the large diameter cylindrical section and the small diameter cylindrical section, the sections being coaxial with each other, the small diameter cylindrical section including an inner surface defining an internal cavity for containing the medicinal, a first end 30 with a first opening 32 and equiangularly spaced, axially aligned evacuation channels 28 in the inner surface for venting air out of the barrel when the internal cavity is filled with the medicinal, and the large diameter cylindrical section includes a second opposite end with a second opening 24; a rubber plunger 58 for pushing the medicinal through the first opening, the plunger being slidably positioned in sealing contact with the inner surface of the small diameter cylindrical section; a plunger rod 86 connected with the plunger and contained within the barrel; a removable cap 40 for sealingly closing off the first opening and for applying a pushing force to the plunger rod when the cap is removed from the sealing relationship with the barrel in order to slidably move the plunger in the small diameter cylindrical section of the barrel to expel the medicinal from the first opening; and a connection assembly 36 for removably connecting the cap to the barrel such that the cap sealingly closes off the first opening. The applicator is useful for introducing medicinals into body cavities.
