  The details of the sanitary tampon according to the present invention will be described below with reference to the accompanying drawings.

  FIG. 1 is a partially broken perspective view of a sanitary tampon 1. The sanitary tampon 1 includes a tampon applicator 10 formed by an outer cylinder 2, an inner cylinder 3 and a guide member 4, and a tampon 5 housed inside the outer cylinder 2. The outer cylinder 2 has a front end portion 6 and a rear end portion 7, and a tampon 5 is accommodated inside the front end portion 6. The front end portion 6 is releasably closed and has a plurality of slits 8 for enabling the opening. The rear end portion 7 is inside the guide member 4 and has a pair of finger hooking projections 11 extending radially outward from a portion facing the outer cylinder 2 in the radial direction. The finger hanging projection 11 extends to the outside of the guide member 4 through a notch 47 formed in the cylindrical portion 41 of the guide member 4. As apparent from FIG. 2, the inner cylinder 3 has a front end portion 31 accommodated inside the outer cylinder 2 and a rear end portion 32 extended from the outer cylinder 2 and accommodated in the guide member 4. The guide member 4 includes a cylindrical portion 41, a stopper flange 43 formed at the front end portion 42 of the cylindrical portion 41, and a disc-shaped end wall 46 formed at the rear end portion 44. Although the cylindrical part 41 has a pair of notch parts 47 in the site | part which opposes in the radial direction, only one notch part 47 of a pair is shown by FIG. The front end portion 42 of the cylindrical portion 41 is formed with a front opening 48 (see FIG. 2) into which the rear end portion 7 of the outer tube 2 is slidably inserted in the length direction of the outer tube 2. A rear opening 49 for passing the take-out string 51 of the tampon 5 is formed in the end wall 46 at the rear end portion 44 of the shaped portion 41.

  2-5 is a figure which shows the use procedure of the sanitary tampon 1, In these figures, the vagina 70, the vagina wall 71, and the vulva part 72 are shown with the virtual line. FIG. 2 is a cross-sectional view taken along the line II-II in FIG. 1, and the sanitary tampon 1 in this figure uses the third finger 77 applied to the end wall 46 so that the flange 43 of the guide member 4 is removed. The outer cylinder 2 is inserted into the vagina 70 until it contacts the pubic part 72. The outer cylinder 2 is not inserted deeper than this even when the end wall 46 is pushed. In the sanitary tampon 1, the tampon 5 is accommodated in the front end portion 6 located in the front of the outer cylinder 2 in the insertion direction. The rear end portion 7 of the outer cylinder 2 extends slidably from the front opening 48 of the guide member 4 to the inside of the cylindrical portion 41, and the finger hanging projection 11 is located behind the flange 43. A gap 76 between which the first and second fingers 73 and 74 indicated by phantom lines can be inserted is formed between the finger hanging projection 11 and the flange 43. The inner cylinder 3 inserted into the outer cylinder 2 has a front end portion 31 in contact with a rear end portion 52 of the tampon 5 from the left side of the figure. The rear end portion 32 of the inner cylinder 3 extends rearward from the rear end portion 7 of the outer cylinder 2 and is in contact with the inner surface of the end wall 46 of the guide member 4 from the right side of the drawing. A third finger 77 indicated by an imaginary line is applied to the outer surface of the end wall 46. Inside the inner cylinder 3, the string 51 from the rear end portion 52 of the tampon 5 extends and goes out of the end wall 46. The end wall 46 has a diameter larger than the outer diameter of the cylindrical portion 41 so that the third finger can be easily applied. In FIG. 2, a virtual line 6 a indicated at the front end 6 of the outer cylinder 2 indicates a state when the front end 6 having the slit 8 is opened.

  In the sanitary tampon 1 of FIG. 3, a force is applied to the third finger 77 applied to the end wall 46 in FIG. 2 to press the flange 43 against the vulva 72. On the other hand, the first and second fingers 73 and 74 are applied to the finger hooking projections 11 to move the outer cylinder 2 in a direction toward the outside of the vagina indicated by an arrow A. At this time, the front end portion 31 of the inner cylinder 3 is in contact with the rear end portion 52 of the tampon 5 from the left side of the figure, and the rear end portion 32 of the inner cylinder 3 is in contact with the inner surface of the end wall 46 of the guide member 4. Since it abuts from the right side of the figure, it is in a stationary state with respect to the inner cylinder 3 and the guide member 4. Therefore, in the outer cylinder 2 moving in the direction of the arrow A, the front end portion 6 having the slit 8 (see FIG. 1) is pressed by the front end portion 50 of the tampon 5 from the inside thereof, whereby the virtual line 6a in FIG. In this way, the tampon 5 is gradually exposed in the resting position in the vagina 70.

  In the sanitary tampon 1 of FIG. 4, the outer cylinder 2 shown in FIG. 3 further moves in the direction of arrow A, and the finger hooking projection 11 of the outer cylinder 2 contacts the end wall 46 of the guide member 4 and stops. The entire tampon 5 is exposed. In other words, the tampon 5 and the applicator 10 are separated in the vagina 70, and only the string 51 remains inside the applicator 10.

  In FIG. 5, the applicator 10 is extracted from the vagina 70 and the tampon 5 remains in the vagina 70. However, the take-out string 51 of the tampon 5 extends to the outside of the vagina 70.

  In the sanitary tampon 1 of the illustrated example, each member of the applicator 10 can be made of thermoplastic synthetic resin such as polyethylene, polypropylene, nylon, polyester, or paper. However, among the applicators 10, the outer cylinder 2 is preferably made of a thermoplastic synthetic resin that is non-water-absorbing and slips well against the vaginal wall 71. The tampon 5 can be made of conventional materials.

  In the sanitary tampon 1 formed in this way, when using it, the outer cylinder 2 formed of a material that is slippery and non-absorbent with respect to the vagina wall 71 may be inserted into the vagina 70, The tampon 5 with good water absorption is not inserted into the vagina 70 in the exposed state, and the vagina wall 71 is not rubbed strongly with the tampon 5, so that the discomfort experienced in the case of a conventional sanitary tampon does not occur. . Further, since the insertion depth of the tampon 5 into the vagina 70 is uniquely determined by bringing the flange 43 of the guide member 4 into contact with the vulva 72, the tampon that has begun to be exposed from the applicator in the vagina as in the prior art. There is no problem that the tampon is not inserted to the required depth due to the frictional force between the vagina and the vagina wall.

  In this invention, when the finger-hanging projections 11 of the outer cylinder 2 are formed on both sides in the radial direction of the outer cylinder 2, there is a case where the sliding of the outer cylinder 2 inside the guide member 4 is likely to be smooth. However, it is also possible to implement the present invention with only one protrusion and only one notch 47 in the guide member 4. Further, the take-out string 51 in the tampon 5 may only extend in the length direction of the inner cylinder 3 without extending from the end wall 46 of the guide member 4. In the end wall 46 in that case, the rear opening 49 becomes unnecessary. For example, when the dimensional difference between the outer diameter of the take-out string 51 and the inner diameter of the inner cylinder 3 is small enough to restrain the free bending of the take-out string 51 inside the inner cylinder 3, the take-out string 51 is straight. Therefore, it is not always necessary for the sanitary tampon 1 that the take-out string 51 extends from the end wall 46.

Divided into an end wall 46b. Further, the cylindrical portion 41 is divided into an upper cylindrical portion 41 a and a lower cylindrical portion 41 b by a notch portion 47, and both the portions 41 a and 41 b are opposed to each other in the radial direction of the cylindrical portion 41.

  The sanitary tampon 1 shown in FIGS. 7 and 8 includes an intermediate assembly 82 including an outer cylinder 2, an inner cylinder 3, and a tampon 5, and a guide member 4 prepared separately from the intermediate assembly 82. It is constituted by. The guide member 4 in FIG. 7 is formed of a thermoplastic synthetic resin, and the flange 43 connected to the front end portion 42 of the cylindrical portion 41 is bent along a virtual line 83 shown in FIG. Then, the upper end wall 46a and the lower end wall 46b divided by the dividing line 81 are expanded in the vertical direction indicated by arrows C and D together with the upper cylindrical portion 41a and the lower cylindrical portion 41b integrally formed therewith. Let it open. The intermediate assembly 82 is inserted from the direction of the arrow B so that the outer cylinder 2 is in front with respect to the guide member 4 expanded in this manner with the front end portion 42 as the base end.

  In FIG. 8, after the outer cylinder 2 is inserted into the guide member 4 until the finger hooking projection 11 of the outer cylinder 2 contacts the front end 47a of the notch 47 in the guide member 4, the upper end wall 46a and the lower end wall are inserted. 46b is moved in the direction opposite to the arrows C and D, and brought into contact with each other so that the dividing line 81 in FIG. 6 is formed. The upper end wall 46a and the lower end wall 46b that are brought into contact with each other are bonded together along the dividing line 81, or are formed so as to snap into each other although not shown. To complete the assembly of the sanitary tampon 1.

  The sanitary tampon 1 illustrated in FIGS. 6 to 8 can take a form in which all members are assembled and supplied to the user as shown in FIG. The solid 82 and the guide member 4 may be separately provided and supplied to the user.
