上述した従来のタンポン用アプリケータは、いずれも把持筒部に滑り止め用の突起を形成しているため、射出成形時の型抜き或いは割り型射出を行う必要がある。一般的にタンポンアプリケータを射出成型する場合、把持筒部の部分はアンダーカット部位となるため無理抜きを主とし、無理抜きの場合には成形品にバリや捲れ等が生じ、タンポン使用時にこれらが使用者の指と干渉するため不快感を与える問題を有している。   Since all of the conventional tampon applicators described above have anti-slip projections formed on the gripping cylinder portion, it is necessary to perform die cutting or split mold injection during injection molding. In general, when a tampon applicator is injection-molded, the gripping cylinder part is an undercut part, so it is mainly forcibly removed. When it is forcibly removed, burrs and creases occur in the molded product. Has the problem of giving discomfort because it interferes with the user's finger.

そこで、本発明は、射出成形の際に把持筒部にバリや捲れが発生することを抑制することにより、使用時の不快感を解消することができるタンポン用アプリケータを提供することを目的とする。   Accordingly, an object of the present invention is to provide a tampon applicator that can eliminate discomfort during use by suppressing the occurrence of burrs and stagnation in the gripping cylinder during injection molding. To do.

請求項１のタンポン用アプリケータは、吸収体が内部に収容され一側に前記吸収体が押し出される押し出し開口が設けられ他側に把持筒部が設けられた外筒と、前記把持筒部内に挿入され外筒内への移動により前記吸収体を押し出し開口から外方へ押し出し可能な内筒とを備えたタンポン用アプリケータであって、前記把持筒部の周方向の全域に複数列の環状凸部が形成され、これらの環状凸部は、前記内筒の把持筒部への挿入側へ向けて把持筒部の外周面からの高さが次第に低くなるように形成されていることを特徴とする。   The applicator for a tampon according to claim 1 includes an outer cylinder in which an absorbent body is housed and an extrusion opening through which the absorbent body is pushed out is provided on one side and a gripping cylinder part is provided on the other side; An tampon applicator provided with an inner cylinder that is inserted and can be pushed out of the opening by pushing the absorber into the outer cylinder, and a plurality of rows of annular applicators are provided in the entire circumferential direction of the gripping cylinder portion Protrusions are formed, and these annular protrusions are formed such that the height from the outer peripheral surface of the gripping cylinder part gradually decreases toward the insertion side of the inner cylinder into the gripping cylinder part. And

請求項２の発明は、請求項１記載のタンポン用アプリケータであって、前記複数列の環状凸部の隣り合う環状凸部間のピッチが異なっていることを特徴とする。   A second aspect of the present invention is the tampon applicator according to the first aspect, characterized in that pitches between adjacent annular convex portions of the plural rows of annular convex portions are different.

請求項３の発明は、請求項１又は請求項２に記載のタンポン用アプリケータであって、前記環状凸部が、前記把持筒部の外周面と平行な頂面と、この頂面の前記内筒挿入側から把持筒部の外周面に対して垂直に延びる垂直面と、頂面の前記吸収体の収容側から把持筒部の外周面に向けて下り傾斜の傾斜面とを有することを特徴とする。   Invention of Claim 3 is the applicator for tampons of Claim 1 or Claim 2, Comprising: The said cyclic | annular convex part is parallel to the outer peripheral surface of the said holding | grip cylinder part, The said top surface of this top surface A vertical surface extending perpendicularly to the outer peripheral surface of the gripping cylinder portion from the inner tube insertion side, and an inclined surface inclined downward from the storage side of the absorber on the top surface toward the outer peripheral surface of the gripping cylinder portion.

請求項４の発明は、請求項１又は請求項３に記載のタンポン用アプリケータであって、前記環状凸部が、頂面が弧状の山形形状の複数の凸部で形成されていることを特徴とする。 Invention of Claim 4 is the applicator for tampons of Claim 1 or Claim 3, Comprising: The said cyclic | annular convex part is formed with the several convex part of the mountain-shaped shape whose top surface is arcuate. Features.

本発明によれば、把持筒部の環状凸部を内筒の把持筒部への挿入側に向けて高さが次第に低くなるように形成しているため、射出成形の際の型抜きを円滑に行うことができる。このため、バリや捲れの発生が抑制でき、タンポン使用時の不快感を解消することができる。又、環状凸部の高さが異なっているため、タンポン使用時における力の調整がし易くなる。   According to the present invention, the annular convex part of the gripping cylinder part is formed so that the height gradually decreases toward the insertion side of the inner cylinder into the gripping cylinder part. Can be done. For this reason, generation | occurrence | production of a burr | flash or a dripping can be suppressed and the discomfort at the time of tampon use can be eliminated. Moreover, since the heights of the annular convex portions are different, it is easy to adjust the force when using the tampon.

図１は本発明の一実施形態のタンポン用アプリケータの全体を示す正面図、図２は図１のＡ部拡大正面図、図３は図２のＢ−Ｂ線断面図、図４は環状凸部の関係を示す断面図、図５は環状凸部の形状を示す断面図、図６は環状凸部の傾斜面の傾斜度αの範囲を説明するグラフである。   1 is a front view showing an entire tampon applicator according to an embodiment of the present invention, FIG. 2 is an enlarged front view of a portion A in FIG. 1, FIG. 3 is a sectional view taken along line BB in FIG. FIG. 5 is a sectional view showing the shape of the annular protrusion, and FIG. 6 is a graph for explaining the range of the inclination degree α of the inclined surface of the annular protrusion.

この実施形態のタンポン用アプリケータ１は、外筒２と内筒３とを有している。これらの外筒２及び内筒３のそれぞれは、ポリエチレン、ポリプロピレン等のポリオレフィンによって全体が形成されている。   The tampon applicator 1 of this embodiment has an outer cylinder 2 and an inner cylinder 3. Each of the outer cylinder 2 and the inner cylinder 3 is entirely formed of polyolefin such as polyethylene or polypropylene.

外筒２の内部には吸収体４が収容されている。吸収体４には取り出し紐５が基端部に連結されている。取り出し紐５は吸収体４の基端部から内筒３の内部を挿通し、その挿通端部が内筒３から抜き出されている。使用中に取り出し紐５を引くことにより、吸収体４を体内から引き出すことができる。   An absorber 4 is accommodated inside the outer cylinder 2. An extraction string 5 is connected to the absorber 4 at the base end. The take-out string 5 is inserted through the inner cylinder 3 from the base end of the absorber 4, and the insertion end is extracted from the inner cylinder 3. The absorbent body 4 can be pulled out from the body by pulling the take-out string 5 during use.

外筒２の先端部分は径の大きな吸収体収容筒部６となっており、基端部分は径の小さな把持筒部７となっている。把持筒部７には内筒３の先端部分が挿入されており、挿入された内筒３の先端面は吸収体４に臨んでいる。吸収体収容筒部６の先端部分は押し出し開口となっており、この押し出し開口には花弁体８が連設されている。花弁体８は常時は押し出し開口の縁部で閉となっているが、内筒３によって吸収体４が押し出されるときに吸収体４によって押し広げられて開口する。これにより、吸収体４が吸収体収容筒部６から押し出されるため吸収体４を体内に挿入することができる。把持筒部７は、このような内筒３の移動操作の際に指によって把持されるグリップ部分となる。   A distal end portion of the outer cylinder 2 is an absorber housing cylinder portion 6 having a large diameter, and a proximal end portion is a gripping cylinder portion 7 having a small diameter. The leading end portion of the inner cylinder 3 is inserted into the gripping cylinder portion 7, and the leading end surface of the inserted inner cylinder 3 faces the absorber 4. The tip of the absorber housing cylinder 6 is an extrusion opening, and a petal body 8 is connected to the extrusion opening. The petal body 8 is normally closed at the edge of the extrusion opening, but when the absorbent body 4 is pushed out by the inner cylinder 3, it is spread and opened by the absorbent body 4. Thereby, since the absorber 4 is extruded from the absorber accommodation cylinder part 6, the absorber 4 can be inserted in a body. The gripping cylinder part 7 becomes a grip part gripped by a finger during such a movement operation of the inner cylinder 3.

図２に示すように、把持筒部７の外周には複数列の環状凸部１１、１２、１３、１４が形成されている。それぞれの環状凸部１１、１２、１３、１４は、図３に示すように把持筒部７の周方向の全域にわたって形成されており、周方向では途切れることのないリング状となっている。   As shown in FIG. 2, a plurality of rows of annular convex portions 11, 12, 13, and 14 are formed on the outer periphery of the gripping cylinder portion 7. As shown in FIG. 3, each of the annular convex portions 11, 12, 13, and 14 is formed over the entire region in the circumferential direction of the gripping cylinder portion 7, and has a ring shape that is not interrupted in the circumferential direction.

複数列の環状凸部１１、１２、１３、１４は、使用者の指が接触することにより滑り止めとして機能する。符号１５は、把持筒部７における内筒３の挿入側に形成された簸かかり部であり、環状凸部１１，１２，１３，１４と同様にリング状に形成されている。簸かかり部１５は隣接している環状凸部１４よりも大径となっていることにより、使用者の指を受け止めるものである。   The plurality of rows of annular convex portions 11, 12, 13, and 14 function as anti-slip when the user's finger comes into contact therewith. Reference numeral 15 denotes a hooking portion formed on the insertion side of the inner cylinder 3 in the gripping cylinder portion 7, and is formed in a ring shape like the annular convex portions 11, 12, 13, and 14. The hooking portion 15 receives a user's finger by having a larger diameter than the adjacent annular convex portion 14.

複数列の環状凸部１１、１２、１３、１４は、内筒３が把持筒部７に挿入される挿入側に向けて把持筒部７の外周面からの高さが次第に低くなるように形成されている。すなわち、図２に示すように吸収体収容筒部６側の環状凸部１１の径が最も大きく、吸収体収容筒部６から離れるのにつれて、すなわち環状凸部１２、１３、１４となるのにつれて径が次第に小さくなっている。これにより図２に示すように、環状凸部１１、１２、１３、１４の頂部を結ぶ頂部線Ｒは内筒３の挿入側に向かって下降する傾斜となっている。   The plurality of rows of annular protrusions 11, 12, 13, 14 are formed such that the height from the outer peripheral surface of the gripping cylinder part 7 gradually decreases toward the insertion side where the inner cylinder 3 is inserted into the gripping cylinder part 7. Has been. That is, as shown in FIG. 2, the diameter of the annular convex portion 11 on the absorber housing cylinder portion 6 side is the largest, and as the distance from the absorber housing cylinder portion 6 increases, that is, as the annular convex portions 12, 13, and 14 become. The diameter is gradually decreasing. As a result, as shown in FIG. 2, the top line R connecting the tops of the annular protrusions 11, 12, 13, and 14 is inclined downward toward the insertion side of the inner cylinder 3.

また、複数列の環状凸部１１、１２、１３、１４は、内筒３が把持筒部７に挿入される挿入側に向けて把持筒部７の外周面からの高さが次第に低くなることを言い換えると、後述する押し出し開口側に向けて把持筒部７の外周面からの高さが次第に高くなるようになっている。これにより、図２に示すように、環状凸部１１、１２、１３、１４の頂部を結ぶ頂部線Ｒは、押し出し開口側側に向かって上昇する傾斜となっている。   In addition, the plurality of rows of annular convex portions 11, 12, 13, and 14 are gradually lowered in height from the outer peripheral surface of the gripping cylinder portion 7 toward the insertion side where the inner tube 3 is inserted into the gripping cylinder portion 7. In other words, the height from the outer peripheral surface of the gripping cylinder portion 7 gradually increases toward the extrusion opening described later. Thereby, as shown in FIG. 2, the top part line R which connects the top part of the cyclic | annular convex parts 11, 12, 13, and 14 becomes the inclination which rises toward the extrusion opening side.

図４は環状凸部１１、１２、１３、１４の高さを比較するものであり、環状凸部１１の高さをＨ１１、環状凸部１２の高さをＨ１２、環状凸部１３の高さをＨ１３、環状凸部１４の高さをＨ１４とした場合、Ｈ１１＞Ｈ１２＞Ｈ１３＞Ｈ１４となるように設定される。例えば、Ｈ１１＝０．４ｍｍ、Ｈ１２＝０．３５ｍｍ、Ｈ１３＝０．３ｍｍ、Ｈ１４＝０．２５ｍｍのように、隣り合う環状凸部の高さを０．０５ｍｍ刻みで異ならせることができる。この場合、環状凸部１１の高さＨ１１は０．１〜１０ｍｍ、より好ましくは０．２〜１ｍｍの範囲で増減させることができ、他の環状凸部の高さＨ１２、Ｈ１３、Ｈ１４は、これよりも順次高さが小さくなるように形成される。   FIG. 4 compares the heights of the annular protrusions 11, 12, 13, and 14. The height of the annular protrusion 11 is H11, the height of the annular protrusion 12 is H12, and the height of the annular protrusion 13 is shown. Is set to H13, and the height of the annular convex portion 14 is set to H14, H11> H12> H13> H14. For example, the height of the adjacent annular protrusions can be made different in increments of 0.05 mm, such as H11 = 0.4 mm, H12 = 0.35 mm, H13 = 0.3 mm, and H14 = 0.25 mm. In this case, the height H11 of the annular protrusion 11 can be increased or decreased in the range of 0.1 to 10 mm, more preferably 0.2 to 1 mm. The heights H12, H13, and H14 of the other annular protrusions are It is formed so that the height is successively smaller than this.

図４において、矢印Ｋは射出成形に用いる金型の抜き方向であり、この抜き方向Ｋに沿って環状凸部１１、１２、１３、１４が次第に低くなっている。このため、型抜きの際の無理抜きが不要となり、無理抜きに起因したバリや捲れを防止することができる。   In FIG. 4, an arrow K is a direction of drawing a mold used for injection molding, and the annular convex portions 11, 12, 13, and 14 are gradually lowered along this drawing direction K. For this reason, it is not necessary to forcibly remove the die, and it is possible to prevent burrs and wrinkles caused by the forcible removal.

本実施形態において、環状凸部１１、１２、１３、１４は、隣り合う環状凸部間のピッチ（間隔）が異なるように形成されるものである。図２及び図４において、Ｐ１は吸収体収容筒部６の基端部と環状凸部１１との間のピッチ、Ｐ２は環状凸部１１と環状凸部１２との間のピッチ、Ｐ３は環状凸部１２と環状凸部１３との間のピッチ、Ｐ４は環状凸部１３と環状凸部１４との間のピッチである。   In the present embodiment, the annular protrusions 11, 12, 13, and 14 are formed such that the pitches (intervals) between adjacent annular protrusions are different. 2 and 4, P1 is a pitch between the base end portion of the absorber housing cylinder portion 6 and the annular convex portion 11, P2 is a pitch between the annular convex portion 11 and the annular convex portion 12, and P3 is an annular shape. P4 is a pitch between the convex portion 12 and the annular convex portion 13, and P4 is a pitch between the annular convex portion 13 and the annular convex portion 14.

この実施形態において、隣接する環状凸部の間のピッチＰ２とＰ３、Ｐ３とＰ４は異なる値に設定される。例えば、Ｐ２＝２．５ｍｍ、Ｐ３＝２．０ｍｍ、Ｐ４＝２．５ｍｍとなるように設定される。この場合、隣接している環状凸部の間のピッチが異なっていれば、隣接していない環状凸部の間のピッチ（Ｐ２とＰ３）は同じであっても良い。   In this embodiment, the pitches P2 and P3 between adjacent annular convex portions, and P3 and P4 are set to different values. For example, P2 = 2.5 mm, P3 = 2.0 mm, and P4 = 2.5 mm are set. In this case, as long as the pitch between the adjacent annular protrusions is different, the pitch between the adjacent annular protrusions (P2 and P3) may be the same.

隣接する環状凸部の間におけるピッチの値の相違の範囲は、０．２〜５ｍｍ、より好ましくは１．５〜３ｍｍが良好である。ピッチの値の相違の範囲が０．２ｍｍ未満では、指が接触したときにピッチの相違を感じることが難しく、５ｍｍを越える場合には、把持筒部７が必要以上に長くなるため好ましくない。なお、吸収体収容筒部６と環状凸部１１との間のピッチＰ１は、把持筒部７の長さに応じて設定することができ、例えばＰ１＝３．０ｍｍとすることができる。   The range of the difference in pitch value between adjacent annular convex portions is preferably 0.2 to 5 mm, more preferably 1.5 to 3 mm. If the range of the difference in pitch value is less than 0.2 mm, it is difficult to feel the difference in pitch when the finger contacts, and if it exceeds 5 mm, the gripping cylinder portion 7 becomes unnecessarily long. In addition, the pitch P1 between the absorber accommodation cylinder part 6 and the cyclic | annular convex part 11 can be set according to the length of the holding cylinder part 7, for example, can be set to P1 = 3.0mm.

このように、隣接する環状凸部の間のピッチを変化させることにより、使用者が把持筒部７を把持したときに、良好なグリップ感を得ることができる。   In this way, by changing the pitch between the adjacent annular convex portions, a good grip feeling can be obtained when the user grips the gripping cylinder portion 7.

本実施例の環状凸部１１、１２、１３、１４は、軸方向断面が台形形状となるように形成される。より具体的には、図５に示すように環状凸部１１（他の環状凸部１２、１３、１４も同様）は、頂面１１ａが把持筒部７の外周面と平行となっており、頂面１１ａからは垂直面１１ｂ及び１１ｃが連設した台形形状に形成されるものである。   The annular convex portions 11, 12, 13, and 14 of the present embodiment are formed so that the axial cross section has a trapezoidal shape. More specifically, as shown in FIG. 5, the annular convex portion 11 (the same applies to the other annular convex portions 12, 13, and 14), the top surface 11 a is parallel to the outer peripheral surface of the gripping cylinder portion 7, From the top surface 11a, the vertical surfaces 11b and 11c are formed in a trapezoidal shape.

垂直面１１ｂは頂面１１ａにおける内筒３の挿入側（図５において右側）の端部から把持筒部７の外周面に対して垂直に延びるように形成される。傾斜面１１ｃは頂面１１ａにおける吸収体４の収容側（吸収体収容筒部６、図５において左側）から把持筒部７の外周面に向けて下り傾斜となって形成される。   The vertical surface 11b is formed so as to extend perpendicularly to the outer peripheral surface of the gripping cylinder portion 7 from the end of the top surface 11a on the insertion side (right side in FIG. 5) of the inner cylinder 3. The inclined surface 11c is formed so as to be inclined downward from the accommodation side of the absorber 4 on the top surface 11a (absorber accommodating cylinder portion 6, left side in FIG. 5) toward the outer peripheral surface of the gripping cylinder portion 7.

環状凸部１１における頂面１１ａ（他の環状凸部１２、１３、１４の頂面も同様）の幅は０．１〜５ｍｍ、より好ましくは０．２〜２ｍｍに設定される。頂面１１ａの幅がこの範囲を逸脱する場合には、射出成形の型抜きの際にバリや捲れが発生して好ましくない。傾斜面１１ｃの下り傾斜の角度は、吸収体収容筒部６の高さとの関係で設定するのが好ましい。   The width | variety of the top surface 11a in the cyclic | annular convex part 11 (The top surface of other cyclic | annular convex parts 12, 13, and 14 is also the same) is set to 0.1-5 mm, More preferably, it is set to 0.2-2 mm. When the width of the top surface 11a deviates from this range, it is not preferable because burrs and sags are generated at the time of injection molding. It is preferable to set the downward inclination angle of the inclined surface 11 c in relation to the height of the absorber housing cylinder portion 6.

すなわち、図６に示すように、環状凸部１１の高さが吸収体収容筒部６の高さの半分とした場合には、把持筒部７の外周面に対する傾斜面１１ｃの角度αは５〜８０°、好ましくは、２０〜６０°の範囲に設定することが好ましい。傾斜面１１ｃの角度が９０°の場合には、射出成形の型抜きの際にバリや捲れが発生し易くなる。かかる傾斜面１１ｃの角度は他の環状凸部１２、１３、１４においても同様に角度に設定されるものである。   That is, as shown in FIG. 6, when the height of the annular protrusion 11 is half the height of the absorber housing cylinder 6, the angle α of the inclined surface 11 c with respect to the outer peripheral surface of the gripping cylinder 7 is 5 It is preferable to set in the range of ˜80 °, preferably 20˜60 °. When the angle of the inclined surface 11c is 90 °, burrs and wrinkles are likely to occur during die cutting of injection molding. The angle of the inclined surface 11c is similarly set to the angle in the other annular convex portions 12, 13, and 14.

以上の実施形態では、複数の環状凸部１１、１２、１３、１４の高さを内筒３の把持筒部７の挿入側に向けて高さが次第に低くなるように形成しているため、型抜きを確実にすることができ、バリや捲れの発生を抑制することができる。又、隣接する環状凸部のピッチを異なるようにしているため、使用者の指に与える簸かかり感覚を高くすることができ、グリップ感が向上する。   In the above embodiment, since the height of the plurality of annular convex portions 11, 12, 13, 14 is formed so that the height gradually decreases toward the insertion side of the gripping cylinder portion 7 of the inner cylinder 3, Die cutting can be ensured, and the occurrence of burrs and wrinkles can be suppressed. In addition, since the pitches of the adjacent annular convex portions are made different, it is possible to increase the feeling of wrinkle given to the user's finger and improve the grip feeling.
