PROBLEM TO BE SOLVED: To develop a method enabling proper supply without leakage in stop, in a cycle of consecutive supply and stop of fluid material having viscosity, such as a batter used in a food factory or the like.SOLUTION: When a uniaxial eccentric screw pump is used to supply fluid material, a tubular tip member for a uniaxial eccentric screw pump is connected to an outlet part of the uniaxial eccentric screw pump. The flow passage of the tip member has an inner diameter reduced in a substantially tapered manner in the vicinity of a connection part between the flow passage and the uniaxial eccentric screw pump outlet part, and an inner diameter identical from the center part of the tip member to the vicinity of the outlet part.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】食品工場等で用いられるバッター等の粘性を有する流動物の連続的な供給・停止のサイクルにおいて、停止時の漏れがなくかつ、好適に供給できる方法を開発することを課題とする。【解決手段】流動物を供給するために一軸偏心ねじポンプを使用する場合において、当該一軸偏心ねじポンプの出口部に接続される管状の先端部材であって、当該先端部材の流路が一軸偏心ねじポンプ出口部との接続部近傍において、略テーパ状に内径が減少し、当該先端部材の中央部~出口部近傍において同一の内径を有する、一軸偏心ねじポンプ用の先端部材。【選択図】図1
