図６乃至図９に、従来の飲料用ストローと飲料容器の刺し込み孔との関係を示してあり、飲料用ストロー先端の直径と飲料容器の刺し込み孔の直径が略等しく、図６及び図８，９に示すように飲料用ストローを垂直方向から刺し込んだり、図７に示すように飲料用ストローを斜め方向より刺し込み孔に刺し込むと、飲料容器上面の刺し込み孔のフイルム部分が図９に示すように飲料容器上面から切り離されて、異物として飲料内に落下することがあった。
この刺し込み孔の切断フイルム部分の飲料内への落下は、飲料内への異物の混入という衛生上好ましくないという課題がある。さらに、飲料用ストローで容器内飲料を吸入する際に、該異物を飲用してしまうという課題がある。
In a commercially available paper beverage container, a drinking straw is attached to the side or back of the container. When drinking the beverage in the container, the attached straw is removed from the side or the back of the container, and this is removed from the paper beverage container. It is inserted into a straw insertion hole provided on the upper surface, and drinks a content beverage.
FIG. 6 to FIG. 9 show the relationship between a conventional drinking straw and the piercing hole of the beverage container, and the diameter of the drinking straw tip and the piercing hole of the beverage container are substantially equal.

また、先端部のカット角度について、現状５０度としているが、先端部を絞ったことから突き刺し強度を低下させないため角度を４６〜４９度が望ましい条件となった。先端部を細くしたことにより飲み口での吸引については、現状品ストローと全く変化なく使用できる。
参考として、出願人は現行品と本発明品サンプルでストロー突き刺し強度を検証した。
測定方法は、プッシュプルゲージにてストローを突き刺して１００ｍｍ／ｍｉｎのスピードで、６．２ｍｍのストロー刺し込み孔に突き刺して貫通するまでの強度（Ｎ）を測定した。下記の強度はサンプル数２０個における平均値である。
１． 現行品ストロー ９．０Ｎ
２． 本発明品ストロー ６．５Ｎ
In addition, the cutting angle of the tip is currently set to 50 degrees, but the angle is preferably 46 to 49 degrees in order not to reduce the piercing strength because the tip is narrowed. By narrowing the tip, it can be used without any change with the current product straw for suction at the drinking mouth.
As a reference, the applicant verified the straw piercing strength with the current product and the product sample of the present invention.
The measuring method measured the intensity | strength (N) until it pierces a straw with a push-pull gauge and penetrates a 6.2 mm straw insertion hole at a speed of 100 mm / min. The following intensities are average values for 20 samples.
1. Current product straw 9.0N
2. Invention product straw 6.5N
