シール部材40は、断面が略円板の円筒形状に構成され、ピストン20のプレート部材21bの第1外形部25の外周に取り付けられる。シール部材40は、上記位置に取り付けられることによって、ピストン20とタンク10との間の部位をシールする。シール部材40の材料は、ピストン20とタンク10との間をシールできれば特に限定されないが、NBR(ニトリルブタジエンゴム)やアクリルゴム、クロロプレンゴム、フッ素ゴム、ポリウレタン等であって、粘性材料に応じて選択される。
ポンプ50は、タンク10から押し出された粘性材料をディスペンサ70等へ圧送できれば特に限定されず、例えばギヤポンプ、プランジャポンプ、スクリューポンプ、ピストンポンプ等を挙げることができる。
次に粘性材料供給方法及び被覆シート30の取り付け方法について説明する。図6は本発明の一実施形態に係る粘性材料供給方法について示すフローチャートである。粘性材料供給方法は、概説すれば、まずタンク10、ピストン20及び被覆シート30等を用意する(ST1、2)。次に、被覆シート30をピストン20へ取り付ける(ST3)。次に、ピストン20の押圧面22により粘性材料を押圧し、吸い込み通路23に粘性材料を圧送する(ST4)。また、被覆シート30の取り付け方法は、図6のST2、ST3にあたり、ピストン20及び被覆シート30の用意と、ピストン20への被覆シート30の取り付けと、を有する。以下、詳述する。
