払出管１００の内側端部１０４において、管状本体１０８の壁１０８ａは、図４により詳細に示す半円形輪郭または縁１１２を形成する軸Ａ－Ａに向かって半径方向内向きに円筒形になっている。輪郭の半径は、０．５０８ｃｍ（０．２０インチ）から０．７６２ｃｍ（０．３０インチ）の間であってもよい。図１～図４に示す実施形態では、輪郭の半径は、約０．６３５ｃｍ（０．２５インチ）である。半円縁１１２は、払出管１００の内側端部１０４に入口開口１１４（図３）を画定する。一実施形態では、入口開口１１４は、４．４４５ｃｍ（１．７５インチ）から５．７１５ｃｍ（２．２５インチ）の間の入口径Ｄ_ｉ（図６）を有してもよい。図１乃至図６に示す払出管１００の実施形態では、入口径、Ｄ_ｉは、約４．８７７ｃｍ（１．９２インチ）である。入口径、Ｄ_ｉは、丸みを帯びた縁１１２の基部１１８における管状本体１０８の内径Ｄ_ｂ（図５）よりも著しくより小さく（約３２％より小さい）、払出管１００の実施形態において、約７．１６３ｃｍ（２．８２インチ）である。 At the inner end 104 of the dispensing tube 100, the wall 108a of the tubular body 108 is cylindrical radially inwardly toward the axis AA forming a semi-circular profile or rim 112 shown in more detail in FIG. there is The contour radius may be between 0.20 inch and 0.30 inch. In the embodiment shown in FIGS. 1-4, the contour radius is approximately 0.25 inch. A semi-circular rim 112 defines an inlet opening 114 (FIG. 3) at the inner end 104 of dispensing tube 100 . In one embodiment, inlet opening 114 may have an inlet diameter D _i (FIG. 6) between 1.75 inches and 2.25 inches. In the embodiment of dispensing tube 100 shown in FIGS. 1-6, the inlet diameter, _Di , is approximately 1.92 inches. The inlet diameter, D _i , is significantly smaller (about 32% less) than the inner diameter D _b ( FIG. 5 ) of the tubular body 108 at the base 118 of the rounded edge 112 , and in an embodiment of the dispensing tube 100 is about It is 7.163 cm (2.82 inches).
