<p>In order to obtain distribution in hygienic conditions of the fluid contained in the can, the improvement comprises a protection element (17), which has a first (8) and a second (9) laminar portion which are superimposed, and connected in a manner which is hermetically sealed, but separable by being pivoted around a hinge (14). The upper surface (13) of the first laminar portion (8) of the protection element (17) becomes the sterile support surface for the upper lip, and the lower surface (12) of the second laminar portion (9) of the protection element (17) becomes the sterile support surface for the lower lip.</p> |
