[Embodiment] Fig. 1 is a front view showing the entirety of a tampon catheter according to an embodiment of the present invention, and Fig. 2 is a cross-sectional view showing an opening portion for pushing out the outer cylinder. The tampon catheter 1 of this embodiment has an outer cylinder 2 and an inner cylinder 3. The entire outer cylinder 2 and the inner cylinder 3 are each formed of a polyolefin such as polyethylene or polypropylene. The absorber 4 is accommodated in the inside of the outer cylinder 2. In the absorbent body 4, the _string 5 is joined to the base end portion thereof. The take-up string 5 is inserted into the inner tube 3 from the base end portion of the absorber 4, and the insertion end portion is pulled out from the inner tube 3, and in use, the absorbent body can be taken by pulling out the string 5 4 Pull out from the body. The distal end portion of the outer tube 2 is an absorbent body accommodating cylinder portion (hereinafter referred to as a accommodating cylinder portion) 6 having a large diameter, and the proximal end portion is a gripping cylinder portion 7 having a small diameter. In the grip tube portion 7, the distal end portion of the inner tube 3 is inserted, and the distal end surface of the inserted inner tube 3 faces the absorber 4. The front end portion of the accommodating tubular portion 6 is an opening for pushing out, and the opening for pushing out is provided with the petal body 8. The flower petal body 8 is normally closed with the edge of the opening, but when the absorbent body 4 is pushed out by the inner tube 3, the absorbent body 4 is opened and opened. Thereby, since the absorbent body 4 is pushed out from the accommodating cylinder portion 6, the absorbent body 4 can be inserted into the body. The grip cylinder portion 7 is a handle portion that is gripped by a finger when the inner cylinder 3 is moved. On the outer peripheral surface of the grip cylinder portion 7, a plurality of projections 7a for receiving the fingers of the user are formed. Further, the inner cylinder 3 can be pressed into the outer cylinder 2 by pushing the inner cylinder -8 - 201008500 3 while the finger is pulled by the projection 7a. Fig. 2 is a cross section of the housing tube portion 6 of the outer tube 2, and the ejection opening 1 is provided on one side (left side). A plurality of petal bodies 8 are attached to the edge of the opening 10 for ejection. Each of the petal bodies 8 is formed such that the base side has a wide width, and the petal shape which gradually narrows in width toward the distal end side often closes the ejection opening 10. In other words, the petal body 12 is flexed in an arc shape toward the central portion in the radial direction of the accommodating tubular portion 6, as shown in Fig. 1, and the opening 10 for ejection is closed by the buckling. As described above, the petal body 8 is opened by being pressed by the absorber 4 in the housing tube portion 6, and is formed in an open state as shown in Fig. 2 . In this embodiment, a means for reducing the opening force of the opening of the petal body 8 is provided in a smooth manner. Hereinafter, the means for reducing the opening force will be described. In Fig. 2, reference numeral 13 is a continuous portion in which the edge portion of the opening 10 is continuous with the petal body 8. The continuous portion 13 is a region that connects the base portion 8a of the petal body 8 in the circumferential direction, and a means for reducing the opening force is provided in this region. As shown in Fig. 2, the thickness of the accommodating tubular portion 6 is gradually thinned from the gripping cylinder portion 7 toward the push-out opening 10, and the thickness of the continuous portion 13 is formed to be the thinnest. By changing the thickness as described above, the outer circumferential diameter D 1 of the continuous portion 13 and the outer circumferential diameter E 1 of the cylindrical portion 7 of the accommodating tubular portion 6 are the same (D 1 = E 1 ) 'the inner diameter of the continuous portion 13 The D2 is larger than the inner diameter E2 of the base side (the grip tube portion 7 side) of the housing tube portion 6 (D2 &gt; E2). By the above relationship, the sectional area of the continuous portion 13 becomes smaller than the sectional area of the receiving tubular portion 6, and the resistance when the petal body 8 connected to the continuous portion 13 is pressed is reduced. Therefore, the opening of the petal body 8 can be smoothly performed. -9- 201008500 Further, it is preferable that the outer circumferential diameter D1 of the continuous portion 13 and the outer circumferential diameter E1 of the holding tubular portion 6 on the side of the holding tubular portion 7 are set to D1 &lt; E1. By making such a dimensional relationship, the pushing force of the petal body 8 can be reduced, and the disordered extraction of the injection molding can be performed. In this embodiment, since the inner diameter D2 of the continuous portion 13 is formed to be larger than the inner diameter E2 of the base portion side of the housing portion 6, the diameter of the absorber 4 can be increased. Therefore, the absorption rate can be improved. Further, when the diameter of the absorber 4 is constant, a space can be generated between the absorber 4 and the housing tube portion 6, so that the housing tube portion 6 can be made to reach the absorber 4 when inserted into the body.

Further, the housing tube portion 6 may be formed into a shape other than a cylinder. 3 to 6 show other embodiments of the means for reducing the opening force, respectively. In the embodiment shown in Fig. 3, the thickness of the portion of the accommodating tubular portion 6 corresponding to the continuous portion 13 of the base portion 8a that connects the petal body 8 is made thinner than the other portions of the accommodating tubular portion 6, and the continuous portion is formed. The corresponding portion of 13 becomes the thin portion 15. By forming the thin portion 15, the resistance of the petal body 8 to the opening motion can be reduced, and the petal body 8 can be smoothly opened. In the embodiment shown in Fig. 4, a notched hole portion 17 is formed in the base portion 8a of the petal body 8. The notch hole portion 17 is provided in the base portion 8a of the petal body 8, so as to be located in the region of the continuous portion 13, and is hung on the base portion 8a of the adjacent flower petal body 8. By providing such a notch hole portion 17, the resistance of the petal body 8 to the opening operation can be reduced, so that the petal body 8 can be smoothly opened. -10-201008500 In the embodiment shown in Fig. 5, one or a plurality of slits 18 are provided in a portion corresponding to the vicinity of the base portion 8a of the petal body 8. The slits 1 8 are provided in the continuous portion 13'. In this embodiment, the cylindrical portion 6 is formed in the radial direction of the cylindrical portion 6 so as to cross the bottom of each of the petals 8. Here, the slit 18 may have a groove shape (a shape that does not penetrate the thickness direction of the accommodating cylinder portion), or may be a thickness direction that penetrates the accommodating cylinder portion. φ In the embodiment shown in Fig. 6, one or a plurality of slits 19 are formed along the axial direction of the housing tube portion 6. The slit 19 is provided at a position corresponding to the base portion 8a of the petal body 8, i.e., the bottom of the petal body 8, whereby the slit 19 is formed in the continuous portion 13. The slits 9 of Fig. 6 are formed along the axial direction of the receiving cylinder portion 6. As shown in Figs. 5 and 6, by forming the slits 18, 19, the resistance of the petal body 8 at the time of pushing out can be reduced, and the petal body 8 can be smoothly opened. In the above embodiment, since the opening force of the petal body 8 is reduced, φ can smoothly open the petal body 8, and the insertion of the absorbent body 4 into the body can be smoothly performed. Therefore, there is no sense of discomfort to the user. Furthermore, in the present invention, the above embodiments can be combined, whereby the opening operation of the petal body can be performed more smoothly. The entire contents of the Japanese Patent Application No. 2008-081965 (filed on March 26, 2008) are hereby incorporated by reference.
