A plurality of cut lines 7 are formed, and a plurality of tongue pieces 8 are formed between the plurality of cut lines 7.

  These tongue pieces 8 are elastically deformed and expanded when the push rod 2 is inserted into the main body 1 as described later and the tablet 3 is sent outward, and elastic when the tablet 3 is sent to the outside. Return to the original shape. In other words, a plurality of tongue pieces that are divided into a plurality in the circumferential direction of the main body 1, protrude toward the front end direction of the main body 1, and are gradually dented in accordance with the front end direction. 8 are provided, and these tongue pieces 8 can be elastically deformed.

  As shown in detail in FIG. 3, an annular projecting portion 21 projecting inward of the main body 1 is formed on the inner surface of the base end portion 9 of the main body 1. As shown in FIG. 1, non-slip annular protrusions 22 are formed on the outer peripheral surface of the base end portion 9 of the main body 1 at regular intervals.

  The push rod 2 is formed in a bottomed cylindrical shape and is made of a resin such as high density polyethylene (HDPE). The cross section (inner surface / outer surface) of the push rod 2 has a perfect circular shape. The distal end portion 31 of the push rod 2 is composed of a side surface 32 formed along a virtual hemispherical circle that bulges toward the distal end, and a distal end wall 33 that is orthogonal to the axis of the push rod 2. The distal end portion 31 of the push rod 2 is positioned on the inner surface side of the tongue piece 8 when the tongue piece 8 formed on the distal end portion 5 of the main body 1 is elastically restored and returned to a fixed position as will be described later. It is possible to hold the tongue piece 8 in that position.

  As shown in FIGS. 1, 2, and 3, the push rod 2 has a protrusion 34 (first protrusion) and a protrusion 35 (second protrusion) that can contact the protrusion 21 of the main body 1. An engagement protrusion 36 is formed.

  The first protrusion 34 is formed linearly on the outer surface of the push rod 2 near the base end portion 37 toward the axial direction of the push rod 2 and extends outward from the outer surface of the push rod 2. A plurality of strips are formed at predetermined intervals in the circumferential direction over a length L with a predetermined projecting dimension T. The first protrusion 34 gets over the protrusion 21 of the main body 1 and advances the push bar 2 into the main body 1 when the pressing force when the push bar 2 is inserted into the main body 1 exceeds a predetermined value P0. In other words, in this case, it is possible to pass through the protruding portion 21, and when the push rod 2 is inserted into the main body 1, when the force for pulling out the push rod 2 from the main body 1 is applied, this removal is performed. Engage with the protruding portion 21 of the main body 1 when the output is less than or equal to the predetermined value P1, and keep the push rod 2 in that position to prevent the push rod 2 from being further retracted from the main body 1 It is.

  The second protrusion 35 is formed on the outer surface of the push rod 2 so as to be positioned on the rear end side of the first protrusion 34. The second protrusion 35 is formed linearly on the outer surface of the push rod 2 in the axial direction of the push rod 2, and a plurality of strips are provided at regular intervals in the circumferential direction of the push rod 2. Is formed. The second protrusion 35 is formed such that at least a part of the second protrusion 35 gradually decreases in length from the proximal end 37 side to the distal end side of the push rod 2, and the pressing force for inserting the push rod 2 Is engaged with the protruding portion 21 of the main body 1 when the pressure is less than or equal to a predetermined value P2, and the push rod 2 is held in that position, and when pressed with a constant pressing force exceeding the predetermined value P2, the main body 1 The push rod 2 has a projecting dimension in which the push rod 2 advances toward the distal end of the main body 1 while generating a frictional force with the projecting portion 21.

  In this embodiment, the total length of the main body 1 is 80 mm to 120 mm, the outer diameter is 9 mm to 17 mm, the inner diameter is 7 mm to 15 mm, the protrusion is 0.1 mm to 0.4 mm, and the total length of the push rod 2 is 80 mm to 125 mm. The outer diameter of the push rod can be 6 mm to 15 mm, and the projecting dimension T of the first protrusion 34 and the second protrusion 35 can be 0.1 mm to 0.3 mm.

  As described above, the first protrusion 34 and the second protrusion 35 are formed on the outer surface of the push rod 2 so as to continuously extend over the length L linearly in the axial direction. However, the shape of these protrusions is not limited to this example as long as the push rod 2 is not greatly displaced in the main body 1. For example, as shown in FIG. The first protrusion 34 may be formed by a plurality of protrusions 34a, 34a,..., And each protrusion 34a may have a discontinuous protrusion shape. The same applies to the second protrusion 35.

In the above-described embodiment, the first protrusion 34 and the second protrusion 35 are formed in the axial direction of the push rod 2. You may form so that it may turn toward a direction (not shown).
Furthermore, as shown in FIG. 7B, for example, a plurality of first protrusions 34 are annularly arranged in the circumferential direction of the push rod 2 at equal intervals, and a recess 40 is formed on the surface of each first protrusion 34. The form to form may be sufficient. According to this aspect, by forming the recess 40 on the surface of the first protrusion 34, it is possible to adjust so as to reduce the frictional resistance with the protrusion 21 of the main body 1. The same applies to the second protrusion 35.

  Furthermore, the predetermined values P0, P1, and P2 are preferably set to 90 gf to 110 gf for P0 and P1 and 150 gf to 190 gf for P2, respectively, from the viewpoint of the user's feeling of use. Therefore, when the main body 1 and the push rod 2 exceed the above numerical values depending on the material or the like, the protrusion heights of the first protrusion 34 and the second protrusion 35 are reduced, and P0, P1, and P2 are set as described above. In order to make it within the range, it can be adjusted by appropriately changing the material of the push rod 2, the protruding dimensions of the protrusions 34, 35, the protruding shape of the protrusions 34, 35, and the like.

The engaging protrusion 36 is provided so as to be connected to a protruding wall portion 38 (second protruding wall portion), which will be described later, of the base end portion 37 of the push rod 2, and is provided on the outer surface of the push rod 2 in a predetermined manner. It is formed in an annular shape with a protruding dimension of.
When the push rod 2 is inserted into the main body 1 and reaches the inner part of the main body 1, the front end surface 36 a of the engaging protrusion 36 comes into contact with the rear end surface 4 b of the main body 1. In this case, the base end portion 37 of the push rod 2 is formed so as to protrude from the rear end surface 4b of the main body 1 by a certain dimension.

The overhanging wall portion 38 is formed in an annular shape so as to protrude outward from the proximal end portion 37 of the push rod 2.
As described above, when the engaging protrusion 36 is engaged with the rear end surface 4 b of the main body 1, the protruding wall portion 38 forms a certain gap with the protruding wall portion 4 of the main body 1. It has come to be.

  Further, when the push rod 2 is inserted to the innermost portion of the main body 1 as described above, that is, when the engagement protrusion 36 of the push rod 2 is inserted to a position where it engages with the rear end surface 4b of the main body 1. 5 (a) and 5 (b), the tip of the tongue piece 8 formed on the tip 5 of the main body 1 comes into contact with the surface 32 of the side of the tip of the push rod 2, and The shape stays in place.

  As shown in FIGS. 1 and 2, the tablet 3 is formed in a flat shape, the planar shape is a bullet-like shape, and the bulging portions 41 and 42 are formed on both surfaces of the flat base 40. (See FIG. 2).

The usage method of said applicator is demonstrated.
The tablet 3 is inserted into the main body 1 from the base end side of the main body 1, and the push rod 2 is further inserted from the base end side of the main body 1. Then, the push rod 2 is advanced to a predetermined position while confirming the position and directionality of the tablet 3. Here, since the protrusion 21 is formed on the inner surface of the base end portion of the main body 1 and the first protrusion 34 is formed on the push rod 2, the protrusion 34 is engaged with the protrusion 21. Match.

  Here, the push rod 2 is pressed with a pressing force exceeding a predetermined value P 0, and the push rod 2 is set at a position where the protrusion 34 exceeds the protrusion 21. In this state, even if the push rod 2 receives a pressing force in the direction of the tip in the main body 1, if the pressing force is not more than a predetermined value P <b> 2, the tip of the second protrusion 35 is the protrusion of the main body 1. If the pulling output in this case is less than or equal to P1 even if a force in the direction of being pulled out from the main body 1 is applied, the rear end portion of the first protrusion 34 is connected to the main body 1. Since it engages with the protruding portion 21 and is held in that position, and can be prevented from inadvertently moving in the axial direction of the main body 1, the push rod 2 presses the tablet 3 to release the tablet 3 to the outside. Therefore, it is possible to prevent the push rod 2 from moving backward from the position and moving the tablet 3 unnecessarily.

  In this state, the operator inserts the applicator into the vagina of the human body and places it in an appropriate position. Even in this state, the tablet 3 is prevented from being accidentally released to the outside. Then, after the operator inserts the applicator into the fixed position and further presses the push rod 2 against the main body 1, the tablet 3 advances. In this case, the second protrusion 35 formed on the outer surface of the push rod 2 abuts on the protrusion 21 of the main body 1, and the push rod 2 moves forward in a state where a frictional force is generated therebetween. Become.

  Therefore, since the operator presses the push rod 2 while feeling a certain load, the tablet 3 is prevented from being rapidly discharged to the outside. At this time, since the second protrusion 35 is formed so that the protrusion height gradually decreases toward the tip of the push rod 2, as the tablet 3 advances forward, the second protrusion 35 is pushed. When the load on the bar 2 is increased and the tablet 3 is released from the tip of the main body 1, rapid release is more reliably prevented. Then, when the tablet 3 is released, as shown in FIGS. 5 (a) and 5 (b), the tongue piece 8 of the main body 1 is spread outward and sent out from the opening 6 to the outside. become.

As shown in FIG. 5A, in the state in which the tablet 3 is released, that is, in the state in which the push bar 2 is inserted to the innermost part of the main body 1, the engaging protrusion of the push bar 2 A front end surface 36 a of 36 abuts on the rear end surface 4 b of the main body 1. Therefore, at this time, the base end portion 37 of the push rod 2 is partially protruded from the rear end face of the main body 1 by a certain dimension, and the overhang wall portion 4 of the main body 1 and the overhang wall portion 38 of the push rod 2 There will be a certain gap between the two.
On the other hand, when the tablet 3 is sent out from the main body 1, the tongue piece 8 of the main body 1 is elastically deformed and expands outward as described above. However, after the tablet 3 is released, the tongue 3 The piece 8 is elastically restored, and its distal end abuts on the side surface 32 of the distal end portion of the push rod 2, and is held in place by the side surface 32.

  Therefore, according to this applicator, the protrusion 21 is provided on the inner surface of the main body 1 and the first protrusion 34 is provided on the outer surface of the push rod 2. The protrusion 34 can be engaged to prevent the push bar 2 from being inadvertently retracted with respect to the main body 1, and the tablet 3 can be moved unnecessarily within the main body or dropped to the outside. Inconveniences such as discharge to the outside can be prevented. Moreover, the tablet 3 can be sent to an appropriate position in the vagina.

  In addition, since the second protrusion 35 is provided on the outer surface of the push rod 2, the protrusion 21 and the protrusion 35 have a predetermined frictional force when the main body 2 is pressed against the main body 1. As a result, the push rod 2 advances, and the operator can operate the push rod 2 while feeling an appropriate load, and the tablet 3 can be pushed out well.

  Furthermore, since the engagement protrusion 36 is provided at the base end portion 37 of the push rod 2, when the push rod 2 is inserted to the innermost part of the main body 1, the base end portion 37 of the push rod 2 has a constant size. It protrudes from the rear end face of 1. Therefore, when the applicator is reused, the push bar 2 can be easily pulled out by grasping the protruding wall portion 38.

  Further, when the push rod 2 is inserted to the innermost part with respect to the main body 1, a predetermined gap is formed between the overhanging wall portion 4 and the overhanging wall portion 38, and therefore, between these The effect that there is no fear of pinching hair is obtained.

Still further, after the tablet 3 is delivered into the vagina using this applicator, when the tongue piece 8 of the main body 1 that has been once expanded returns to its original position after being elastically restored, Since the tongue piece 8 is held on the side surface 32 of the distal end portion of the push rod 2, the tongue piece 8 is not displaced spontaneously, and even if the tongue piece 8 is pressed against the inner surface of the vagina, the tongue piece 8 is not displaced carelessly. The effect that the user does not feel uncomfortable is obtained.
Further, according to this applicator, it is possible to prevent the push rod 2 from being detached from the main body 1 when the used applicator is detached from the body.

6 (a) and 6 (b) are explanatory diagrams showing the usage state of another embodiment of the present invention. This embodiment is different from the above-described embodiment in the shape of the tongue piece 8 portion of the distal end portion of the main body 1.
In the shape of the tongue piece 8 described above, as shown in FIGS. 5A and 5B, only the distal end portion of the tongue piece 8 is the push rod 2 when the distal end portion of the push rod 2 feeds the tablet 3. In this embodiment, the push rod 2 holds the tongue piece 8. However, according to this embodiment, the tongue formed at the tip of the main body 1 after the push rod 2 feeds out the tablet 3. The piece 8 is configured to be held at the position following the side surface of the front end portion of the push rod 2. Also in this embodiment, after the tip of the push rod 2 feeds the tablet 3, the entire tip side surface 32 of the push rod 2 holds the inner surface of the tongue piece 8, so that the tongue piece 8 can be securely placed in that position. Can be held in.
