A delivery cap for containers of liquids is disclosed comprising: a first cylindrical body with an outer wall with a lower threaded portion so as to be coupled with a threaded body belonging to the container and an inner wall coaxial to the first wall and defining together with a cylindrical central element an upper annular opening for liquid passage; a second cylindrical body coaxial to the first body and slidingly connected to the second inner wall of the first body, the second body having a cylindrical central wall defining together with the first body a chamber receiving the liquid coming out from the annular opening and ending with a duct for liquid discharge from the cap. The second body has a lid with a cylindrical edge portion sliding on the inner surface of the first outer wall belonging to the first body, the edge portion being linked with a lateral handling element with vertical development and slidingly coupled on the outer wall of the first body. The cylindrical central wall of the second body moves relative to the inner wall of the first body from a lower position closing the liquid delivery duct to a top position of duct opening.

1. A delivery cap for containers of liquids comprising:a first generally cylindrical body having an outer wall provided with a lower internally threaded part to be coupled with a corresponding externally threaded neck of said container and a generally cylindrical inner wall coaxial to said outer wall, defining together with a central cylindrical element, an annular top opening for passage of said liquid coming from said container; a second generally cylindrical body coaxial to said first body and slidingly connected to said inner wall of said first body through a generally cylindrical central wall defining together with said first body a chamber adapted to receive said liquid coming out from said annular opening and ending with a duct for discharge of liquid from said cap, said second body having a lid with a cylindrical edge portion sliding on the inner surface of said outer wall of said first body, and being linked with a lateral handling element with generally vertical development, sliding in a recess made on the outer wall of said first body, wherein the lower edge of said recess is connected to said internal wall by an inclined plane extending upwards of said first body and cooperating with the free end of said handling element to move upwards said the second body when said handling end is pushed against said inclined plane. 2. The cap according to claim 1) wherein said inclined plane comprises one or more ribs having a generally triangular profile when seen in longitudinal section.3. The cap according to claim 1) wherein said handling element has the general shape of a cylindrical portion of the first outer wall belonging to said first body.4. The cap according to claim 1) wherein said free end of said handling element has generally horizontal projecting ribs.5. The cap according to claim 1) wherein said lid of said second body has a generally flat top surface.6. The cap according to claim 1) wherein the delivery duct belonging to said second body has a first cylindrical stretch with vertical axis and a generally horizontal second tubular stretch.7. The cap according to claim 6) wherein the tight closure of said delivery duct is obtained by contact between the walls of said first cylindrical stretch and said second tubular stretch of said delivery duct with the lateral walls of said central cylindrical element belonging to said first body.8. The cap according to claim 1) wherein said delivery duct of said second body is a cylindrical cavity with vertical axis and coaxial to the axis of said second and first body ending with a generally circular hole.9. The cap according to claim 8) wherein the tight closure of said delivery duct is obtained by contact of the wall of said cylindrical cavity of said second body with the lateral walls of said cylindrical central element belonging to said first body, said delivery hole being closed by a frustum conical surface superposed to said cylindrical central element.
