Description

本発明はクリーム絞り用カップリングに関し，とくにクリーム絞り袋の先端に絞り口金を交換可能に装着するためのカップリングに関する。 The present invention relates to a cream squeeze coupling, and more particularly to a coupling for mounting a squeeze base to a tip of a cream squeeze bag in a replaceable manner.

図４は，ケーキ・ペストリー等の洋菓子に生クリーム，バタークリーム等を絞り出してデコレーション（飾り）を施すための絞り袋４０の一例を示す。図示例の絞り袋４０は，例えば布製，紙製又は合成樹脂製の三角形の袋であり，一辺を開放して投入口４１ａとし，先端を所定大きさカットして口金孔４１ｂとしたものである。絞り袋４０の内側から口金孔４１ｂにクリーム絞り口金（ノズル）３０を装着し，投入口４１ａから絞り袋４０内にクリームＣを詰め込む。詰め込んだクリームＣを絞り袋４０の側面に圧力を加えることで口金３０の先端から絞り出し，口金３０を移動させながら洋菓子上にクリームＣで所望の模様や文字を描いてデコレーションを仕上げる。図示例の絞り袋４０と絞り口金３０は，デコレーションを仕上げる場合だけでなく，シュークリームの内部にカスタードクリーム等を絞り入れる場合等にも使用される。 FIG. 4 shows an example of a squeeze bag 40 for squeezing fresh cream, butter cream, etc. into a pastry such as a cake or pastry for decoration. The illustrated squeeze bag 40 is, for example, a triangular bag made of cloth, paper, or synthetic resin. One side is opened to form an inlet 41a, and the tip is cut to a predetermined size to form a base hole 41b. . A cream squeezing base (nozzle) 30 is attached from the inside of the squeezing bag 40 to the base hole 41b, and the cream C is stuffed into the squeezing bag 40 from the insertion port 41a. The packed cream C is squeezed from the tip of the base 30 by applying pressure to the side surface of the squeeze bag 40, and the decoration is finished by drawing a desired pattern and characters with the cream C on the confectionery while moving the base 30. The squeezing bag 40 and the squeezing base 30 in the illustrated example are used not only when finishing the decoration, but also when squeezing custard cream or the like inside the cream puff.

絞り口金３０は，例えば図５（Ｅ）のような扇形状の金属薄板３２の直線辺３３ａ，３３ｂを溶接して円錐状とし，その先端に図５（Ａ）〜図５（Ｄ）のような花弁形，丸口形，鋸刃形，モンブラン形等の様々な形状の絞り孔３１を形成したものである。円錐状の口金３０は，筆先のような形状となるので，クリームＣで模様や文字を描きやすい利点を有している。また，絞り孔３１の大きさに応じて底面径が異なる円錐状を採用し，例えば図５（Ａ），（Ｂ）のように絞り孔３１ａが小さいときは底面径の小さい円錐状口金３０ａ（以下，小径口金３０ａということがある）とし，図５（Ｃ），（Ｄ）のように絞り孔３１ｂが大きいときは底面径の大きい円錐状口金３０ｂ（以下，大径口金３０ｂということがある）とすることができる。 The aperture base 30 is formed into a conical shape by welding linear sides 33a and 33b of a fan-shaped metal thin plate 32 as shown in FIG. 5E, for example, as shown in FIGS. 5A to 5D. A variety of apertures 31 such as a petal shape, a round mouth shape, a saw blade shape, and a Montblanc shape are formed. Since the conical base 30 has a shape like a brush tip, it has an advantage that a pattern or characters can be easily drawn with the cream C. Further, a conical shape having a different bottom surface diameter is adopted according to the size of the throttle hole 31. For example, when the throttle hole 31a is small as shown in FIGS. Hereinafter, it may be referred to as a small-diameter base 30a), and when the throttle hole 31b is large as shown in FIGS. 5C and 5D, it may be referred to as a conical base 30b having a large bottom diameter (hereinafter referred to as a large-diameter base 30b). ).

図５のように絞り孔３１ａ，３１ｂの形状や大きさの異なる複数の口金３０ａ，３０ｂを使い分けることにより，クリームＣを異なる太さや形状で絞り出し，様々なデコレーションを仕上げることができる。ただし，図４の方法では絞り袋４０にクリームＣを詰めたまま口金３０を交換することができないので，口金３０の使い分けに手間がかかる。このため，図６〜図７に示すように，絞り袋４０にクリームＣを詰めたまま絞り口金３０を交換するためのカップリング（連結器）と呼ばれる器具が開発されている（特許文献１〜３参照）。図６に示すカップリング５０は，外周面上に雄ネジ部５３が形成された先細り筒状ホルダー５１（同図（Ａ）参照）と，その雄ネジ部５３に螺着する雌ネジ部５６が内周面に形成された口金用ナット５５ｂ（同図（Ｂ）参照）とで構成されている。 As shown in FIG. 5, the cream C can be squeezed with different thicknesses and shapes by using a plurality of bases 30a and 30b having different shapes and sizes of the throttle holes 31a and 31b, and various decorations can be finished. However, in the method of FIG. 4, the base 30 cannot be replaced while the cream C is packed in the squeezed bag 40, so it takes time to properly use the base 30. For this reason, as shown in FIGS. 6-7, the instrument called the coupling (connector) for replacing | exchanging the squeeze base 30 with cream C packed in the squeezing bag 40 has been developed (Patent Documents 1 to 7). 3). A coupling 50 shown in FIG. 6 includes a tapered cylindrical holder 51 (see FIG. 6A) having a male threaded portion 53 formed on the outer peripheral surface, and a female threaded portion 56 that is screwed to the male threaded portion 53. It consists of a nut 55b (see FIG. 5B) formed on the inner peripheral surface.

図６のカップリング５０は，同図（Ｃ）に示すように，先ず筒状ホルダー５１の雄ネジ部５３より基端側（大径側）のテーパー状外周面５２を絞り袋４０の口金孔４１ｂに取り付け，筒状ホルダー５１の雄ネジ部５３とその先端側（小径側）の円錐台状周壁５４とを口金孔４１から外に突出させる。次いで，突出させた円錐台状周壁５４に円錐状口金３０（図５参照）を被せたのち，同図（Ｄ）に示すように，ナット５５ｂを口金３０の先端側から嵌め込んで雌ネジ部５６をナット５５ｂの雄ネジ部５３に螺合させ，ナット５５ｂの係止部５７で口金３０の外周面を押さえることにより口金３０を筒状ホルダー５１の円錐台状周壁５４に固定する。同図（Ｄ）は，大径口金３０ｂ（図５（Ｃ），（Ｄ）参照）を筒状ホルダー５１の周壁５４に底部まで嵌合させて固定した状態を表わし，同図（Ｅ）はその断面図を表わす。 As shown in FIG. 6C, the coupling 50 shown in FIG. 6 first has a tapered outer peripheral surface 52 on the base end side (larger diameter side) than the male threaded portion 53 of the cylindrical holder 51. The male threaded portion 53 of the cylindrical holder 51 and the frustoconical peripheral wall 54 on the tip side (smaller diameter side) of the cylindrical holder 51 are projected outward from the base hole 41. Next, after the conical base 30 (see FIG. 5) is put on the protruding frustoconical peripheral wall 54, the nut 55b is fitted from the front end side of the base 30 as shown in FIG. 56 is screwed into the male threaded portion 53 of the nut 55b, and the base 30 is fixed to the frustoconical peripheral wall 54 of the cylindrical holder 51 by pressing the outer peripheral surface of the base 30 with the locking portion 57 of the nut 55b. FIG. 4D shows a state in which the large-diameter base 30b (see FIGS. 5C and 5D) is fitted and fixed to the peripheral wall 54 of the cylindrical holder 51 to the bottom, and FIG. The sectional view is shown.

図７は，カップリング５０の筒状ホルダー５１を絞り袋４０の口金孔４１ｂに取り付けたのち，大径口金３０ｂに代えて，筒状ホルダー５１の周壁５４に中間高さまでしか嵌合しない小径口金３０ａ（図５（Ａ），（Ｂ）参照）を固定する手法を示す。すなわち，図６（Ｂ）のような大径口金用ナット５５ｂに代えて，図７（Ｂ）のような小径口金３０ａ用の小径口金用ナット５５ａを用いることにより，図７（Ｃ）に示すように絞り袋４０内にクリームＣを詰めたまま大径口金３０ｂと小径口金３０ａとを相互に交換することができる。同図（Ｄ）は，小径口金３０ａを筒状ホルダー５１の周壁５４の先端部に固定した状態を表わし，同図（Ｅ）はその断面図を表わす。同図（Ｄ）及び（Ｅ）から分かるように，図７に示す小径口金用ナット５５ａは，図６に示す大径口金用ナット５５ｂに比べて係止部５７が長く，その係止部５７により小径口金３０ａの外周面を筒状ホルダー５１の円錐台状周壁５４の先端部に押し付けて固定することができる。 FIG. 7 shows a small-diameter base that is fitted to the peripheral wall 54 of the cylindrical holder 51 only to an intermediate height after the cylindrical holder 51 of the coupling 50 is attached to the base hole 41b of the squeeze bag 40, instead of the large-diameter base 30b. A method of fixing 30a (see FIGS. 5A and 5B) is shown. That is, instead of the large-diameter base nut 55b as shown in FIG. 6B, a small-diameter base nut 55a for the small-diameter base 30a as shown in FIG. As described above, the large-diameter base 30b and the small-diameter base 30a can be exchanged with each other while the cream C is packed in the squeezed bag 40. FIG. 4D shows a state in which the small-diameter base 30a is fixed to the distal end portion of the peripheral wall 54 of the cylindrical holder 51, and FIG. 7 (D) and (E), the small diameter cap nut 55a shown in FIG. 7 has a longer locking portion 57 than the large diameter cap nut 55b shown in FIG. Thus, the outer peripheral surface of the small-diameter base 30a can be pressed and fixed to the tip of the frustoconical peripheral wall 54 of the cylindrical holder 51.

図８は，図６〜図７のように円錐状口金３０ａ，３０ｂを用いるのではなく，フランジ３５付き凸型口金３４を用いるカップリング６０を示す（特許文献４参照）。図８のカップリング６０は，先細り筒状周壁６４の外周面にナット保持部（雄ネジ部）６３を設けた中空筒状ホルダー６１（同図（Ａ）参照）と，そのホルダー６１の先端頂壁６４ａに密着可能なフランジ３５を有する金属薄板の絞り成形体の凸部３６に絞り孔３７を設けた凸型口金３４（同図（Ｂ），（Ｅ）参照）と，ホルダー６１の保持部６３に嵌合しつつ口金３４のフランジ３５をホルダー６１の先端頂壁６４ａに密着させて保持する口金用ナット６５（同図（Ｃ）参照）とにより構成されている。絞り成形体の凸状口金３６は，図５のように溶接作業を必要とする円錐状口金３０ａ，３０ｂに比べて加工費を低く抑えることができ，使用できる期間（寿命）も長くできる利点を有している。また，図８（Ｅ）のように絞り孔３７の大きさや形状が異なる様々な絞り成形体を簡単に製造することができ，図８（Ｆ）のように絞り孔３７のない絞り成形体を絞り袋４０の蓋口金３８として利用することもできる。 FIG. 8 shows a coupling 60 that uses a convex die 34 with a flange 35 instead of using the conical die 30a, 30b as in FIGS. 6 to 7 (see Patent Document 4). 8 includes a hollow cylindrical holder 61 (see FIG. 8A) in which a nut holding portion (male thread portion) 63 is provided on the outer peripheral surface of a tapered cylindrical peripheral wall 64, and a tip end of the holder 61. A convex die 34 (see FIGS. 7B and 7E) provided with a throttle hole 37 in the convex portion 36 of the metal sheet drawn molding having a flange 35 capable of being in close contact with the wall 64a, and a holding portion of the holder 61 A base nut 65 (see FIG. 3C) that holds the flange 35 of the base 34 in close contact with the tip top wall 64 a of the holder 61 while being fitted to the base 63. As shown in FIG. 5, the convex base 36 of the drawn molded body has an advantage that the processing cost can be kept lower than that of the conical bases 30a and 30b that require welding work, and the usable period (life) can be extended. Have. In addition, various drawn bodies having different sizes and shapes of the throttle holes 37 as shown in FIG. 8 (E) can be easily manufactured. As shown in FIG. It can also be used as the lid base 38 of the air bag 40.

図８に示すカップリング６０は，同図（Ａ）に示すように，筒状ホルダー６１のテーパー状外周面６２を絞り袋４０の口金孔４１ｂに取り付けたのち，同図（Ｄ）に示すように，口金孔４１ｂから突出させた先細り筒状周壁６４の先端頂壁６４ａに凸型口金３４のフランジ３５を位置合わせする。そして，ナット６５の嵌合部（雌ネジ部）６６をナット保持部６３と結合するまでホルダー６１に嵌合させ，ナット６５の先細り薄肉周壁６７の先端の縮径部７０により口金３４のフランジ３５をホルダー６１の先端頂壁６４ａに密着させて保持する。ホルダー６１のナット保持部６３から先端頂壁６４ａまでの間隔Ｌを長くすることにより，口金３４の凸部３６の高さｈが小さい場合でも，模様や文字を描くために十分な長さの筆先のような先細り形状を確保することができる。 As shown in FIG. 8A, the coupling 60 shown in FIG. 8A is shown in FIG. 8D after attaching the tapered outer peripheral surface 62 of the cylindrical holder 61 to the cap hole 41b of the air bag 40. Then, the flange 35 of the convex die 34 is aligned with the tip top wall 64a of the tapered cylindrical peripheral wall 64 protruding from the die hole 41b. Then, the fitting portion (female screw portion) 66 of the nut 65 is fitted to the holder 61 until it is coupled to the nut holding portion 63, and the flange 35 of the base 34 is formed by the reduced diameter portion 70 at the tip of the tapered thin peripheral wall 67 of the nut 65. Is held in close contact with the top end wall 64 a of the holder 61. By increasing the distance L from the nut holding part 63 of the holder 61 to the tip top wall 64a, the brush tip having a sufficient length for drawing a pattern or characters even when the height h of the convex part 36 of the base 34 is small. Such a tapered shape can be ensured.

図６〜図７に示す筒状ホルダー５１と大径口金用ナット５５ｂと小径口金用ナット５５ａとを組み合わせたカッププリング５０を用いることにより，絞り袋４０内にクリームＣを詰めたまま，絞り孔３１の形状や大きさの異なる円錐状口金３０ａ，３０ｂを自在に使い分けることが可能となる。しかし，従来のカップリング５０は，口金３０ａ，３０ｂを交換したときにクリームＣの絞り出し圧力（絞り出し感覚）に相違を生じることが経験されている。すなわち，図６（Ｅ）及び図７（Ｅ）に示すように，小径口金３０ａと大径口金３０ｂとを交換可能とするためには，筒状ホルダー５１の先端開口径ｒを小径口金３０ａの底面径より小さくする必要がある。このため，クリームＣを口金に送り込むホルダー５１の先端開口径ｒは，図７（Ｆ）に示すように小径口金３０ａの絞り孔３１ａに対して十分大きさとすることはできるが，図６（Ｆ）に示すように大径口金３０ｂの絞り孔３１ｂに対しては相対的に小さくなり，大径口金３０ｂの装着時にクリームＣが絞り出しにくいという違和感を生じさせる。 By using the coupling 50 in which the cylindrical holder 51, the large-diameter cap nut 55b, and the small-diameter cap nut 55a shown in FIGS. The conical bases 30a and 30b having different shapes and sizes of 31 can be used properly. However, it has been experienced that the conventional coupling 50 causes a difference in the squeezing pressure (squeezing sensation) of the cream C when the caps 30a and 30b are replaced. That is, as shown in FIGS. 6 (E) and 7 (E), in order to exchange the small-diameter base 30a and the large-diameter base 30b, the tip opening diameter r of the cylindrical holder 51 is set to be smaller than that of the small-diameter base 30a. It is necessary to make it smaller than the bottom diameter. Therefore, the tip opening diameter r of the holder 51 for feeding the cream C into the base can be made sufficiently large with respect to the throttle hole 31a of the small diameter base 30a as shown in FIG. ), The diameter of the large-diameter base 30b is relatively small with respect to the throttling hole 31b, and the cream C is difficult to squeeze out when the large-diameter base 30b is mounted.

図８のようなカップリング６０を用い，絞り孔３７の形状や大きさは異なるが凸部３６の口径が等しい凸型口金３４を用いるようにすれば，口金３４の交換によるクリームＣの絞り出し圧力の相違をなくすことができる。しかし，図８（Ｅ）のような凸型口金３４では図５の円錐状口金３０の筆先のような作業性が得られない場合があり，円錐状口金３０と同様のデコレーションを仕上げることが難しい場合もある。様々なデコレーションを効率的に仕上げるため，絞り袋４０にクリームＣを詰めたまま，図５のような小径口金３０ａ及び大径口金３０ｂを自在に使い分けることができ，しかも交換時にクリームＣの絞り出し圧力（絞り出し感覚）に大きな相違を生じさせないようなカップリングの開発が望まれている。 If the coupling 60 as shown in FIG. 8 is used and the convex die 34 having the same diameter as the convex portion 36 is used although the shape and size of the throttle hole 37 are different, the squeezing pressure of the cream C by the replacement of the die 34 The difference can be eliminated. However, the convex base 34 as shown in FIG. 8E may not provide the workability like the brush tip of the conical base 30 shown in FIG. 5, and it is difficult to finish the same decoration as the conical base 30. In some cases. In order to efficiently finish various decorations, the small bag 30a and the large bottle 30b as shown in FIG. The development of a coupling that does not cause a large difference in the squeezing feeling is desired.

そこで本発明の目的は，口金の交換時にクリームの絞り出し圧力に大きな相違を生じさせないクリーム絞り用カップリングを提供することにある。 SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a cream squeezing coupling that does not cause a large difference in the squeezing pressure of the cream when the base is changed.

図１は，本発明のクリーム絞り用カップリング１の実施例を示す。図示例のカップリング１は，先細り円錐台状で所定高さｈ１の筒状周壁１１を有する図１（Ａ）のような中空ホルダー１０と，中空ホルダー１０の筒状周壁１１の外面に嵌め合わせて被せる所定高さｈ１の嵌合周壁２１を有する図１（Ｂ）のような口金用ナット２０とにより構成されている。 FIG. 1 shows an embodiment of a cream squeezing coupling 1 according to the present invention. The coupling 1 in the illustrated example is fitted to the hollow holder 10 as shown in FIG. 1A having a tapered truncated cone shape and a cylindrical peripheral wall 11 having a predetermined height h1 and the outer surface of the cylindrical peripheral wall 11 of the hollow holder 10. And a cap nut 20 as shown in FIG. 1B having a fitting peripheral wall 21 with a predetermined height h1.

図１（Ａ）に示すように，中空ホルダー１０の先端側の先細り筒状周壁１１には先端開口１７から底部に至る切欠き１４を設け，切欠き１４の基端側（底端開口側）の底部外面にナット保持部１５を設け，更にナット保持部１５の基端側に絞り袋４０の口金孔４１ｂに取り付けるための環状凹凸付きのテーパー状外周面１６を設ける。また，図１（Ｂ）に示すように，口金用ナット２０の軸心孔２２にはホルダー１０のナット保持部１５と位置合わせして結合するホルダー結合部２５を設ける。ホルダー１０の保持部１５及びナット２０の結合部２５はそれぞれ雄ネジ，雌ネジとすることができるが，例えば保持部１５又は結合部２５を磁石として両者を磁力により結合してもよい。 As shown in FIG. 1A, the tapered cylindrical peripheral wall 11 on the distal end side of the hollow holder 10 is provided with a notch 14 extending from the distal end opening 17 to the bottom, and the proximal end side (bottom end opening side) of the notch 14 is provided. A nut holding portion 15 is provided on the outer surface of the bottom of the base plate, and a tapered outer peripheral surface 16 with an annular unevenness is provided on the base end side of the nut holding portion 15 to be attached to the cap hole 41b of the squeezing bag 40. As shown in FIG. 1B, a holder coupling portion 25 is provided in the axial hole 22 of the cap nut 20 so as to be aligned and coupled with the nut holding portion 15 of the holder 10. The holding portion 15 of the holder 10 and the coupling portion 25 of the nut 20 can be a male screw and a female screw, respectively. For example, the holding portion 15 or the coupling portion 25 may be used as a magnet, and both may be coupled by magnetic force.

図示例のカップリング１は，図６〜図７に示した従来のカップリング５０と同様にクリーム絞り袋４０に装着することができる。すなわち，図１（Ｐ１）に示すように，先ず絞り袋４０の口金孔４１ｂに中空ホルダー１０のテーパー状外周面１６を装着し，ナット保持部１５と先細り筒状周壁１１とを口金孔４１から突出させる。次いで，突出させたホルダー１０の筒状周壁１１に円錐状の大径口金３０ｂを被せ，その口金３０ｂの先端側から口金用ナット２０を嵌め込み，ナット２０の嵌合周壁２１をホルダー１０の筒状周壁１１の外面に嵌合させる。更に，ナット２０の結合部２５をホルダー１０の保持部１５と結合することにより，口金３０ｂを筒状周壁１１に固定する。図１（Ｑ１）は，大径口金３０ｂに代えて，小径口金３０ａを中空ホルダー１０の先細り筒状周壁１１に固定する様子を示す。 The coupling 1 in the illustrated example can be attached to the cream squeeze bag 40 in the same manner as the conventional coupling 50 shown in FIGS. That is, as shown in FIG. 1 (P1), first, the tapered outer peripheral surface 16 of the hollow holder 10 is attached to the cap hole 41b of the squeeze bag 40, and the nut holding portion 15 and the tapered cylindrical peripheral wall 11 are connected from the cap hole 41. Make it protrude. Next, the cylindrical peripheral wall 11 of the protruded holder 10 is covered with a conical large-diameter base 30b, a base nut 20 is fitted from the tip side of the base 30b, and the fitting peripheral wall 21 of the nut 20 is connected to the cylindrical shape of the holder 10. The outer wall of the peripheral wall 11 is fitted. Further, the base 30 b is fixed to the cylindrical peripheral wall 11 by connecting the connecting portion 25 of the nut 20 to the holding portion 15 of the holder 10. FIG. 1 (Q1) shows a state in which the small-diameter base 30a is fixed to the tapered cylindrical peripheral wall 11 of the hollow holder 10 instead of the large-diameter base 30b.

図１（Ｐ２）は中空ホルダー１０と大径口金３０ｂとナット２０とを結合させた状態のカップリング１の断面図を表わし，同図（Ｐ３）はその結合状態におけるホルダー１０の先端開口径ｒと大径口金３０ｂの絞り孔３１ｂとの関係を示す。図示例の大径口金３０ｂは，ホルダー１０の筒状周壁１１の底部まで嵌合する口径のものである。これに対して，図１（Ｑ２）は中空ホルダー１０と小径口金３０ａとナット２０とを結合させた状態のカップリング１の断面図を表わし，同図（Ｑ３）はその結合状態におけるホルダー１０の先端開口径ｒと小径口金３０ａの絞り孔３１ｂとの関係を示す。図示例の小径口金３０ａは，ホルダー１０の筒状周壁１１に中間深さｈ３までしか嵌合しない口径のものである。 FIG. 1 (P2) shows a cross-sectional view of the coupling 1 in a state where the hollow holder 10, the large-diameter base 30b, and the nut 20 are coupled, and FIG. 1 (P3) shows the tip opening diameter r of the holder 10 in the coupled state. And the throttle hole 31b of the large-diameter base 30b. The large-diameter base 30 b in the illustrated example has a diameter that fits to the bottom of the cylindrical peripheral wall 11 of the holder 10. On the other hand, FIG. 1 (Q2) shows a sectional view of the coupling 1 in a state where the hollow holder 10, the small diameter cap 30a and the nut 20 are coupled, and FIG. 1 (Q3) is a diagram of the holder 10 in the coupled state. The relationship between the tip opening diameter r and the throttle hole 31b of the small diameter cap 30a is shown. The small-diameter base 30a in the illustrated example has a diameter that only fits to the cylindrical peripheral wall 11 of the holder 10 up to the intermediate depth h3.

図１（Ｐ３）から分かるように，本発明のカップリング１は中空ホルダー１０の筒状周壁１１に先端開口１７から底部に至る切欠き１４を設けているので，ホルダー１０の底端開口１８から取り入れたクリームＣを筒状周壁１１の先端開口１７だけでなく切欠き１４からも大径口金３０ｂへ送り出すことができる。すなわち，図６（Ｅ）を参照して上述したように，従来のカップリング５０は大径口金３０ｂにクリームＣを送り出す口径が筒状ホルダー５１の先端径ｒに限定されているのに対し，本発明のカップリング１は切欠き部１４においてクリームＣの送り出し口径を筒状ホルダー５１の底部径Ｒにまで広げることができ，大径口金３０ｂの装着時にもクリームＣが絞り出しにくいという違和感を避けることができる。 As can be seen from FIG. 1 (P3), the coupling 1 of the present invention is provided with a notch 14 extending from the front end opening 17 to the bottom on the cylindrical peripheral wall 11 of the hollow holder 10, so that the bottom end opening 18 of the holder 10 The incorporated cream C can be delivered to the large-diameter base 30 b not only from the front end opening 17 of the cylindrical peripheral wall 11 but also from the notch 14. That is, as described above with reference to FIG. 6 (E), the conventional coupling 50 has a diameter for feeding the cream C to the large-diameter base 30b limited to the tip diameter r of the cylindrical holder 51. The coupling 1 of the present invention can widen the delivery diameter of the cream C to the bottom diameter R of the cylindrical holder 51 in the notch portion 14, and avoids the uncomfortable feeling that the cream C is difficult to squeeze out even when the large-diameter base 30b is attached. be able to.

また，図１（Ｑ３）に示すように，本発明のカップリング１は，クリームＣの送り出し口径を広げつつ，筒状ホルダー１０の先端径ｒを小径口金３０ａの口径より小さくすることができる。従って，絞り袋４０にクリームＣを詰めたまま，図５（Ａ）及び（Ｂ）のような小径口金３０ａと図５（Ｃ）及び（Ｄ）のような大径口金３０ｂとを交換しながら自在に使い分けることを可能とし，しかも交換時にクリームＣの絞り出し圧力（絞り出し感覚）に大きな相違を生じさせないようにすることができる。 Further, as shown in FIG. 1 (Q3), the coupling 1 of the present invention can make the tip diameter r of the cylindrical holder 10 smaller than the diameter of the small diameter base 30a while widening the delivery diameter of the cream C. Accordingly, while the squeezed bag 40 is filled with the cream C, the small-diameter base 30a as shown in FIGS. 5A and 5B and the large-diameter base 30b as shown in FIGS. 5C and 5D are exchanged. It is possible to use them freely, and it is possible to prevent a significant difference in the squeezing pressure (squeezing sensation) of the cream C during replacement.

好ましくは，図２に示すように，中空ホルダー１０の筒状周壁１１の先端からナット保持部１５に至る外面全体に嵌合する小径口金用ナット２０ａ（図２（Ｂ）参照）と共に，中空ホルダー１０の筒状周壁１１の中間高さｈ２からナット保持部１５に至る外面に嵌合する大径口金用ナット２０ｂ（図２（Ｃ）参照）を組み合わせて用いる。図１（Ｐ１）及び（Ｐ２）に示すように，小径口金用ナット２０ａのみを用いて大径口金３０ｂをホルダー１０の周壁１１に固定することもできるが，大径口金３０ｂの外面がナット２０ａの嵌合周壁２１で覆われてしまうので，大径口金３０ｂを用いた本来の作業性が損なわれるおそれがある。図２（Ｐ１）及び（Ｐ２）に示すように，大径口金３０ｂに交換するときは，その基端部（中間高さｈ２）のみを覆う大径口金用ナット２０ｂを用いることにより，大径口金３０ｂの本来の筆先のような作業性を確保することができる。なお，図２（Ｑ１）及び（Ｑ２）に示すように，小径口金３０ａに交換するときは，図１（Ｑ１）及び（Ｑ２）と同様の小径口金用ナット２０ａを用いることができる。 Preferably, as shown in FIG. 2, the hollow holder 10 is fitted together with a small diameter cap nut 20a (see FIG. 2B) that fits the entire outer surface from the tip of the cylindrical peripheral wall 11 to the nut holding portion 15. A large-diameter base nut 20b (see FIG. 2 (C)) fitted to the outer surface from the intermediate height h2 of the ten cylindrical peripheral walls 11 to the nut holding portion 15 is used in combination. As shown in FIGS. 1 (P1) and (P2), the large-diameter base 30b can be fixed to the peripheral wall 11 of the holder 10 using only the small-diameter base nut 20a, but the outer surface of the large-diameter base 30b is the nut 20a. Therefore, the original workability using the large-diameter base 30b may be impaired. As shown in FIGS. 2 (P1) and (P2), when replacing the large-diameter base 30b, a large-diameter base nut 20b that covers only the base end (intermediate height h2) is used. Workability like the original brush tip of the base 30b can be ensured. As shown in FIGS. 2 (Q1) and (Q2), when replacing the small-diameter base 30a, a small-diameter base nut 20a similar to FIGS. 1 (Q1) and (Q2) can be used.

更に好ましくは，図１（Ａ）及び図２（Ａ）に示すように，中空ホルダー１０の筒状周壁１１に，先端開口１７の周縁に沿って複数の切欠き１４を均等間隔で設ける。ホルダー１０の筒状周壁１１には少なくとも１つの切欠き１４を設ければ足り，単独の切欠き１４によりクリームＣの送り出し口径を広げることもできるが，切欠き１４が単独であると絞り出されるクリームＣに偏りが生じ，デコレーションの仕上げ効率を低下させるおそれがある。ホルダー１０の周壁１１に複数の切欠き１４を均等間隔で設けることにより，切欠き１４から絞り出されるクリームＣの偏りをなくし，デコレーションの仕上げ効率の低下を避けることができる。望ましくはホルダー１０の周壁１１に３以上の切欠き１４を均等間隔で設け，更に望ましくは図示例のように４個の切欠き１４を十文字状に配置して設ける。 More preferably, as shown in FIGS. 1 (A) and 2 (A), a plurality of notches 14 are provided at equal intervals along the periphery of the tip opening 17 in the cylindrical peripheral wall 11 of the hollow holder 10. It is sufficient if at least one notch 14 is provided in the cylindrical peripheral wall 11 of the holder 10, and the delivery diameter of the cream C can be widened by the single notch 14, but the notch 14 is squeezed out when it is alone. There is a possibility that the cream C is biased and the finishing efficiency of the decoration is lowered. By providing a plurality of cutouts 14 at equal intervals on the peripheral wall 11 of the holder 10, the unevenness of the cream C squeezed out from the cutouts 14 can be eliminated, and a reduction in the finishing efficiency of the decoration can be avoided. Preferably, three or more cutouts 14 are provided at equal intervals on the peripheral wall 11 of the holder 10, and more preferably four cutouts 14 are arranged in a cross shape as shown in the illustrated example.

なお，図示例では，中空ホルダー１０の筒状周壁１１に，先端開口１７の所定角度部分を筒状周壁１１の底部まで所定幅で切り取って直線帯状の切欠き１４を形成しているが，切欠き１４の形状は直線帯状に限定されるわけではない。図１（Ｐ３）に示すように，大径口金３０ｂを筒状周壁１１に固定したときにクリームＣの十分な送り出し面積が確保できるように，切欠き１４の適当な形状を任意に選択することができる。また，複数の切欠き１４を設けた場合は，切欠き１４毎に形状を相違させることも可能である。 In the illustrated example, a straight band-shaped cutout 14 is formed on the cylindrical peripheral wall 11 of the hollow holder 10 by cutting a predetermined angle portion of the tip opening 17 to the bottom of the cylindrical peripheral wall 11 with a predetermined width. The shape of the notch 14 is not limited to a straight strip shape. As shown in FIG. 1 (P3), an appropriate shape of the notch 14 is arbitrarily selected so that a sufficient delivery area of the cream C can be secured when the large-diameter base 30b is fixed to the cylindrical peripheral wall 11. Can do. In addition, when a plurality of notches 14 are provided, the shape of each notch 14 can be different.

ただし，中空ホルダー１０に複数の切欠き１４を設けると筒状周壁１１の強度が小さくなり，周壁１１が破損しやすくなるおそれがある。このための対策として，例えばホルダー１０の周壁１１の厚さを適当に調製することにより，周壁１１の強度低下を小さく抑えることができる。或いは図３に示すように，ホルダー１０の筒状周壁１１の中間高さｈ２に段差１２を設けて高さを小さくすることにより，周壁１１の強度低下を小さく抑えることも可能である。すなわち，図３（Ａ）に示すように，中空ホルダー１０の筒状周壁１１を，所定高さｈ２の先細り円錐台状の下層周壁１１ａと所定高さｈ３の先細り円錐台状の上層周壁１１ｂとを軸心合わせして積み重ね，更に上層円錐台１１ｂの下底径を下層円錐台１１ａの上底径より小さくして中間高さｈ２に段差１２を設けた段差付き筒状周壁１１とする。 However, if the hollow holder 10 is provided with a plurality of notches 14, the strength of the cylindrical peripheral wall 11 is reduced, and the peripheral wall 11 may be easily damaged. As a countermeasure for this, for example, by appropriately adjusting the thickness of the peripheral wall 11 of the holder 10, it is possible to suppress a decrease in strength of the peripheral wall 11. Alternatively, as shown in FIG. 3, it is possible to suppress a decrease in strength of the peripheral wall 11 by providing a step 12 at the intermediate height h <b> 2 of the cylindrical peripheral wall 11 of the holder 10 to reduce the height. That is, as shown in FIG. 3A, the cylindrical peripheral wall 11 of the hollow holder 10 is divided into a tapered frustoconical lower peripheral wall 11a having a predetermined height h2 and an upper peripheral wall 11b having a tapered frustoconical shape having a predetermined height h3. The lower peripheral diameter of the upper truncated cone 11b is made smaller than that of the lower truncated cone 11a to form a stepped cylindrical peripheral wall 11 having a step 12 at an intermediate height h2.

図３（Ａ）に示すように，ホルダー１０の周壁１１に段差１２を設けて周壁１１の高さを抑えることにより，複数の切欠き１４を設けた周壁１１にも十分な強度を与えることができる。必要に応じて，図３（Ａ）のホルダー１０の周壁１１の厚さを適当に調製し，周壁１１の強度を更に高めることも可能である。図３（Ｐ３）及び（Ｑ３）に示すように，ホルダー１０の周壁１１に段差１２を設けた場合にも，その周壁に先端開口１７から底部に至る切欠き１４を設けることにより，クリームＣの送り出し口径を筒状ホルダー５１の底部径Ｒにまで広げることができる。 As shown in FIG. 3A, by providing a step 12 on the peripheral wall 11 of the holder 10 to suppress the height of the peripheral wall 11, sufficient strength can be given to the peripheral wall 11 provided with a plurality of notches 14. it can. If necessary, the thickness of the peripheral wall 11 of the holder 10 in FIG. 3A can be appropriately adjusted to further increase the strength of the peripheral wall 11. As shown in FIGS. 3 (P3) and (Q3), even when the step 12 is provided on the peripheral wall 11 of the holder 10, the notch 14 extending from the tip opening 17 to the bottom is provided on the peripheral wall, thereby The delivery aperture can be expanded to the bottom diameter R of the cylindrical holder 51.

図３（Ｂ）は，中空ホルダー１０の段差付き筒状周壁１１に小径口金３０ａを固定するための小径口金用ナット２０ａを示す。この場合は小径口金用ナット２０ａに，図３（Ｑ２）の断面図に示すように，ホルダー１０の下層周壁１１ａの外面に嵌合する所定高さｈ２の嵌合周壁２１ａと，上層周壁１１ｂの外面に嵌合する所定高さｈ３の嵌合周壁２１ｂとを積み重ねた段差付き嵌合周壁を含めることができる。また図３（Ｃ）は，段差付き筒状周壁１１に大径口金３０ｂを固定するための大径口金用ナット２０ｂを示す。大径口金用ナット２０ｂには，図３（Ｐ２）の断面図に示すように，所定高さｈ２の下層周壁１１ａの外面にのみ嵌合する嵌合周壁２１ａを含めれば足りる。 FIG. 3B shows a small-diameter base nut 20 a for fixing the small-diameter base 30 a to the stepped cylindrical peripheral wall 11 of the hollow holder 10. In this case, as shown in the sectional view of FIG. 3 (Q2), the fitting peripheral wall 21a having a predetermined height h2 that fits the outer surface of the lower peripheral wall 11a of the holder 10 and the upper peripheral wall 11b A fitting peripheral wall with a step formed by stacking a fitting peripheral wall 21b having a predetermined height h3 that fits on the outer surface can be included. FIG. 3C shows a large-diameter base nut 20 b for fixing the large-diameter base 30 b to the stepped cylindrical peripheral wall 11. As shown in the sectional view of FIG. 3 (P2), the large-diameter nut 20b only needs to include a fitting peripheral wall 21a that fits only on the outer surface of the lower peripheral wall 11a having a predetermined height h2.

こうして本発明の目的である「口金の交換時にクリームの絞り出し圧力に大きな相違を生じさせないクリーム絞り用カップリング」の提供が達成できる。 Thus, the provision of “a coupling for cream squeezing that does not cause a large difference in the squeezing pressure of the cream when the base is changed” can be achieved.

図３のように，中空ホルダー１０の筒状周壁１１ａ，１１ｂの段差１２を設けた場合は，その段差面１２を利用して，図８（Ｅ）のような絞り成形体の凸型口金３４を本発明のカップリング１に組み合わせることができる。すなわち，図３（Ｒ２）及び（Ｒ３）に示すように，中空ホルダー１０の上層周壁１１ｂを覆う凸型口金３４のフランジ３５をホルダー１０の周壁１１の段差面１２に着座させることができる。この場合は，図３（Ｄ）に示すように，ホルダー１０の周壁１１の段差面１２からナット保持部１５に至る外面に嵌合する凸型口金用ナット２０ｃを用い，そのナット２０ｃの結合部２５をホルダー１０の保持部１５と結合させつつ，そのナット２０ｃの嵌合周壁２１の先端の縮径部２７により凸型口金３４のフランジ３５をホルダー１０の周壁１１の段差面１２に密着させて固定することができる。 When the step 12 of the cylindrical peripheral walls 11a and 11b of the hollow holder 10 is provided as shown in FIG. 3, the stepped surface 12 is used to make the convex die 34 of the drawn compact as shown in FIG. Can be combined with the coupling 1 of the present invention. 3 (R2) and (R3), the flange 35 of the convex die 34 covering the upper peripheral wall 11b of the hollow holder 10 can be seated on the stepped surface 12 of the peripheral wall 11 of the holder 10. In this case, as shown in FIG. 3D, a convex base nut 20c fitted to the outer surface from the stepped surface 12 of the peripheral wall 11 of the holder 10 to the nut holding portion 15 is used, and the coupling portion of the nut 20c is used. 25, the flange 35 of the convex die 34 is brought into close contact with the step surface 12 of the peripheral wall 11 of the holder 10 by the reduced diameter portion 27 at the tip of the fitting peripheral wall 21 of the nut 20c. Can be fixed.

図３（Ｒ２）及び（Ｒ３）に示す凸型口金３４の一例は，図８（Ｅ）のように凸部３６の先端にモンブラン形のクリーム絞り孔３７が形成された絞り成形体である。図１及び図２に示す円錐状口金３０ａ，３０ｂは，筆先のような作業性を有するものの，その絞り孔３１をモンブラン形のように大きくすることは難しい場合がある。本発明のカップリング１に凸型口金３４を組み合わせることにより，円錐状口金３０ａ，３０ｂだけでなく図８（Ｅ）のような凸型口金３４を使い分けることが可能となり，仕上げるデコレーションの幅を広げることができる。 An example of the convex die 34 shown in FIGS. 3 (R2) and (R3) is a drawn molded body in which a Montblanc cream squeezing hole 37 is formed at the tip of the convex portion 36 as shown in FIG. 8 (E). Although the conical bases 30a and 30b shown in FIGS. 1 and 2 have workability like a brush tip, it may be difficult to enlarge the aperture 31 like a Montblanc shape. By combining the convex base 34 with the coupling 1 of the present invention, it becomes possible to selectively use not only the conical bases 30a and 30b but also the convex base 34 as shown in FIG. 8E, thereby widening the range of decorations to be finished. be able to.

また，図３（Ｒ２）及び（Ｒ３）に示す凸型口金３４を，図８（Ｆ）のように絞り孔３７のない蓋状の絞り成形体とすることも可能である。図１及び図２のような絞り出し方法では，絞り袋４０に詰め込んだクリームＣが使用後に残った場合等に口金３０ａ，３０ｂに蓋をする適切な方法がなく，クリームＣが漏れ出すおそれがあり，逆にクリームＣ内に埃が混入する等の衛生上の懸念があった。図８（Ｆ）のように絞り孔３７のない凸型口金３４を蓋口金としてすることにより，絞り袋４０に残ったクリームＣを簡単に保存及び保護することが可能となる。 Further, the convex die 34 shown in FIGS. 3 (R2) and 3 (R3) can be formed into a lid-like drawn body having no drawn holes 37 as shown in FIG. 8 (F). In the squeezing method as shown in FIGS. 1 and 2, there is no appropriate method of covering the bases 30a and 30b when the cream C packed in the squeezing bag 40 remains after use, and the cream C may leak out. On the contrary, there was a concern about hygiene such as dust mixed in the cream C. As shown in FIG. 8 (F), by using the convex base 34 without the throttle hole 37 as a lid base, the cream C remaining in the throttle bag 40 can be easily stored and protected.
