Abstract
Description
後者の場合に、本発明のカートリッジは、有利には、材料の混合および吐出の両方に適している。本発明のカートリッジは、特に、歯科用材料の吐出に使用され得る。
-長手方向軸を有し、吐出孔が設けられた遠位壁を備えるスリーブと、
-材料を収容するように構成されたチャンバを画定するバレルであって、前記バレルは、近位開口端と、遠位端に破断可能な遠位壁とを備え、バレルの遠位壁がスリーブの遠位壁から離れている第1の位置と、バレルの遠位壁の封止部分がスリーブの遠位壁の内面と接触している第2の位置との間で長手方向軸に沿ってスリーブ内を移動するように構成される、バレルと、
-バレルのチャンバを封止するように構成されたピストンであって、前記ピストンは、バレルのチャンバ内で封止係合して移動するように構成されたプレートを備える、ピストンと、
を備える、カートリッジであり、
スリーブは吐出孔の近傍に内部穿孔要素を備え、穿孔要素は第1の位置から第2の位置へのバレルの移行時にバレルの遠位壁を破断するように構成される、カートリッジである。一実施形態によれば、穿孔要素は針ではないか、または針を備えない。
相補的な傾斜面は、穿孔要素および吐出孔に近いバレルとスリーブとの間の境界面を効率的に封止し、このことがバレルとスリーブとの間の隙間における材料の通過を制限し、その結果、最適な吐出制御を確実にする。
-材料の吐出を開始する第1のステップにおいて、ピストンの近位端に加えられるスラスト力の作用下で、バレルの遠位壁がスリーブの遠位壁と接触して穿孔要素によって破断されるまで第1の位置から第2の位置へとスリーブに対してバレルを変位させ、この第1のステップにおいてバレルとピストンとを互いに一体的に移動させるステップと、
-ピストンの近位端に加えられるスラスト力の作用下で吐出ノズルから材料を吐出する第2のステップにおいて、ピストンをバレルに対して変位させるステップと
を含む方法である。
