<p>A novel and improved applicator has been devised for insertion of hygienic mediums, such as, for example, suppositories or tampons, either rectally or vaginally, respectively. The applicator is characterized by having an outer tube provided with a segmental, tapered end which is so formed and constructed as to avoid sharp edges along the segmental end portions and avoid any possibility of damage or injury to sensitive membranes or body tissue when the applicator is inserted. A removable plunger is insertable into the outer tube for the purpose of advancing the hygienic medium through the tube and is characterized by having a tapered end which is limited in its extent of projection through the tube so as to assure complete discharge of the hygienic medium through the segmental end of the tube without expanding the segmental ends beyond the outer diameter of the tube. Limit stops and locator pins are provided between the applicator tube and plunger to limit the distance of movement of the plunger through the tube, and a gripping ring is so formed on the external surface of the tube as to facilitate handling of the applicator. A method of manufacturing has been devised for high volume production of the applicator tube and plunger under close tolerances and in a minimum number of steps and specifically wherein any special cutting or forming operations following extrusion are avoided.</p> |
