Abstract

La présente invention concerne un procédé amélioré de production d'une cape cervicale jetable par moulage par injection, et des capes cervicales ainsi produites. Ce procédé consiste à déterminer un point d'injection sur un emplacement de la partie supérieure d'une cavité de moulage chauffée et à injecter dans cette cavité de moulage chauffée, à ce point d'injection, une matière de moulage élastomère. La matière s'écoule dans la cavité de moulage vers le bas, produisant une cape moulée (10) comportant un rebord annulaire (18) sensiblement plus épais et un dôme (12) épousant la forme et comportant une partie supérieure (20) généralement plus épaisse avec des surfaces intérieure et extérieure, et une partie centrale (22) sensiblement mince.
