DEVICE FOR DELIVERING AN OBJECT TO A CAVITY An applicator for delivering an object, such as a menstrual tampon, to a cavity, such as the vaginal canal, which applicator is not much longer than the object when delivered to the user, is provided. The applicator is a unitary injection blowmolded device which includes a first tubular section housing the object, a second collapsible and extensible corrugated tubular section abutting the first section, and a third tubular section abutting the second section and serving primarily as a handle. An integral pusher member is formed in the interior of the applicator attached to the inner wall of the third section, and is biased to assume a position along the centerline of the applicator. The applicator is delivered to the user in a collapsed state, with the pusher alongside the object in the first section. The user extends the object by pulling on the first and third sections, withdrawing the pusher from the first section so that it aligns itself behind the center of the object. The applicator is inserted in the cavity and the object is ejected by pushing the third section toward the first section, collapsing the second section and driving the pusher member forward. |
