Claim 4:
5. A tap for dispensing liquids from flexible containers, the tap comprising:
a main containing body equipped on a first side with a liquid delivery end, and equipped on an opposing second side with an end designed to make a connection with a liquid container;
a cap for activating dispensing operations placed above the liquid delivery end; and
a stem for opening and closing a dispensing of liquids, placed inside the liquid delivery end and operatively coupled to the cap;
wherein the main containing body includes, on the first side, a cylinder inside which the following are obtained: an upper seat for external sealing of the cap; an internal sealing geometry designed to hermetically mate with an internal geometry of the cap; a cylindrical geometry within which four arms are obtained, at 90° degrees to each other, which connect to a central cylinder and form the guide geometry of the stem; a conical sealing geometry, designed to couple with the conical geometry of the stem generating, when the tap is in a closed position, a hermetic seal;
wherein the stem includes: an undercut attachment geometry, designed to cooperate with a complementary geometry obtained on the cap; a relieved elongated part; and a conical geometry on which a ring geometry is obtained which is coupled with the conical geometry obtained on the body, generating the hermetic seal of the tap;
wherein the four arms are not connected with a lower part of the tap but with an upper part of the tap, preventing post-molding deformations from being transmitted to the conical sealing geometry, but at the same time also remaining far from the upper seat and the internal sealing geometry, thereby creating a guide area of the stem placed almost centrally in the main containing body.
