Abstract

Disclosed are reusable tampon applicators, methods of use, and methods of manufacture thereof. A reusable tampon applicator comprises a cylindrical body, and a pusher for pushing a tampon through the cylindrical body during tampon application. The cylindrical body comprises a base opening at a distal end for inserting the tampon into a straight barrel connected to a convex apex at a proximal end. The convex apex comprises a slit opening for the tampon to pass through during tampon application. The slit opening extends from the proximal end to the distal end to form a full slit on a first lateral side of the cylindrical body; it further extends from the proximal end towards the distal end to form a partial slit on a second lateral side. Such reusable tampon applicators provide a hygienic and eco-friendly alternative to disposable tampon applicators.

Claims (44)

1. A tampon applicator, comprising:

a body for holding a tampon for tampon application, the body comprising a distal end, a proximal end, and a base at the distal end including an opening for inserting the tampon into a barrel connected to a convex apex at the proximal end,

wherein the convex apex comprises one or more slit openings to form more than one petals for the tampon to pass through during tampon application, wherein a slit opening extends along the barrel laterally from the proximal end to the distal end and through the base to form a full slit, wherein the body further comprises flexible folds or flaps configured to allow the full slit to open partially; and

a pusher, for telescopic insertion into the body, and for pushing the tampon out from the one or more slit openings during tampon application.

2. The tampon applicator of claim 1 , further comprising:

a case for telescopically enclosing the body and the pusher.

3. The tampon applicator of claim 1 , wherein the pusher comprises at least one notch on an external lateral surface for securing the pusher and the body while not in use.

4. The tampon applicator of claim 1 , wherein the pusher comprises a circular rim to secure the pusher and the body while not in use.

5. The tampon applicator of claim 1 , wherein the body comprises at least one latch or notch for securing the body and the pusher while not in use.

6. The tampon applicator of claim 1 , wherein the body comprises:

a base grip portion at the distal end of the body, wherein an external diameter of the base grip portion is larger than an external diameter of the barrel.

7. The tampon applicator of claim 1 , wherein the distal end of the body comprises a flat base surface, the flat base surface for standing the body on a flat surface.

8. The tampon applicator of claim 1 , wherein a distal end of the pusher comprises a flat base surface, the flat base surface for standing the pusher on a flat surface.

9. The tampon applicator of claim 1 , wherein the pusher comprises:

a proximal portion, and a base grip portion at a distal end of the pusher,

wherein an external diameter of the proximal portion is smaller than an internal diameter of the base opening of the body, and

wherein an external diameter of the base grip portion of the pusher is larger than the internal diameter of the base opening of the body.

10. The tampon applicator of claim 1 , wherein the pusher is at least one of sealed at a proximal end of the pusher, or sealed at a distal end of the pusher.

11. The tampon applicator of claim 1 , wherein the tampon applicator is washable and reusable.

12. A tampon applicator hygiene pack, comprising:

a tampon;

a tampon applicator, comprising:

a body for holding a tampon for tampon application, the body comprising a distal end and a proximal end, and a base at the distal end including an opening for inserting the tampon into a barrel connected to a convex apex at the proximal end, wherein the convex apex comprises one or more slit openings to form more than one petals for the tampon to pass through during tampon application, wherein a slit opening extends along the barrel laterally from the proximal end to the distal end and through the base to form a full slit, wherein the body further comprises flexible folds or flaps configured to allow the full slit to open partially, and

a pusher, for telescopic insertion into the body, and for pushing the tampon out from the one or more slit openings during tampon application; and

a carrying purse.

13. The tampon applicator hygiene pack of claim 12 , wherein the pusher is at least one of sealed at a proximal end of the pusher, or sealed at a distal end of the pusher.

14. The tampon applicator hygiene pack of claim 12 , wherein the body comprises:

a base grip portion at the distal end of the body, wherein an external diameter of the base grip portion is larger than an external diameter of the barrel.

15. A method for manufacturing a tampon applicator, comprising the steps of:

forming a body, the body comprising a distal end and a proximal end,

wherein the distal end comprises a base including an opening for inserting a tampon into a barrel connected to a convex apex at the proximal end,

wherein the convex apex comprises one or more slit openings to form more than one petals for the tampon to pass through during tampon application, wherein a slit opening extends along the barrel laterally from the proximal end to the distal end and through the base to form a full slit, wherein the body further comprises flexible folds or flaps configured to allow the full slit to open partially; and

forming a pusher, for telescopic insertion into the body, and for pushing the tampon out from the one or more slit openings during tampon application.

16. The method of claim 15 , wherein the forming of the body comprises bounding an inner plastic support layer and an outer silicone layer.

17. The method of claim 15 , wherein the pusher is at least one of sealed at a proximal end of the pusher, or sealed at a distal end of the pusher.

18. The method of claim 15 , wherein the body comprises:

a base grip portion at the distal end of the body, wherein an external diameter of the base grip portion is larger than an external diameter of the barrel.

19. A tampon applicator, comprising:

a body for holding a tampon for tampon application, the body comprising a distal end and a proximal end, and an opening at a base at the distal end of the body for inserting the tampon into a barrel connected to a convex apex at the proximal end,

wherein the convex apex comprises one or more slit openings to form more than one petals for the tampon to pass through during tampon application, wherein a slit on the body allows a tampon string to pass through the slit on the body from below the base at the distal end to the proximal end during tampon application; and

a pusher, for telescopic insertion into the body, and for pushing the tampon out from the one or more slit openings during tampon application.

20. The tampon applicator of claim 19 , wherein the pusher is at least one of sealed at a proximal end of the pusher, or sealed at a distal end of the pusher.

21. The tampon applicator of claim 19 , wherein the body comprises:

a base grip portion at the distal end of the body, wherein an external diameter of the base grip portion is larger than an external diameter of the barrel.
