CA 2621218

A cap, which is detachably connectable to an optical head of an endoscope, has a tubular housing, which is manufactured by injection molding from translucent plastic material. The housing includes a rear open end and a frontal end closed by a frontal face and an antiglare ring for preventing a viewer of the optical head from viewing parasitic reflections. The antiglare ring is embedded within the frontal face of the cap and said optical head can view an object of interest through a portion of the frontal face which is confined by the antiglare ring. The antiglare ring is provided with at least one discontinuity region through which the plastic material can flow during injection molding of the cap.

L'invention concerne un bouchon pouvant être appliqué de manière détachable sur la tête optique d'un endoscope et qui comporte un corps tubulaire, fabriqué par moulage par injection à partir d'une matière plastique transparente. Le corps comprend une extrémité arrière ouverte; une extrémité avant fermée par une face frontale; et un anneau antireflet, qui empêche les reflets parasites d'atteindre l'utilisateur de la tête optique. L'anneau antireflet est intégré dans la face frontale du bouchon, et la tête optique permet de voir un objet examiné à travers une partie de la face frontale délimitée par ledit anneau. L'anneau antireflet comporte au moins une région de discontinuité par laquelle la matière plastique peut s'écouler pendant le moulage par injection du bouchon.
