1. A cap for a container, in particular for liquid foods, such as orange juice and other similar drinks, comprising: attachment means suitable to mechanically attach the cap in a releasable manner to at least one further similar cap,wherein the attachment means comprise axial attachment means with the further cap which is axially overlapping the previous cap, andwherein the axial attachment means comprise at least one axially projecting tooth, the tooth is suitable to engage with a skirt of the further similar cap, and further comprising, a central body having an axial extension, closed by a base at a top, and provided with a threading on the inside suitable for connection with the container; wherein the skirt which surrounds the central body is annular and has a top surface, joined to the central body;wherein the skirt is radially spaced from the central body to form a passage open to passage of air at least by the skirt having an upper free edge which defines the passage in the top surface and the skirt has a lower free edge, at the lower end of the central body on the side opposite the base. 2. The cap according to claim 1, wherein the skirt has a main axis, and wherein the skirt comprises a lateral attachment means with the skirt of the further cap laterally attachable to the previous cap. 3. The cap according to claim 2, wherein the lateral attachment means comprises a first plurality of spaced ribs projecting from the skirt, forming respective seats between each other, suitable to receive a second plurality of respective ribs of the further similar cap. 4. The cap according to claim 3, wherein the first plurality of ribs are divided in annularly separate groups, wherein a first group of ribs contains a different number of ribs to a second adjacent group. 5. The cap according to claim 4, wherein the first group of ribs comprises two or three ribs. 6. The cap according to claim 2, wherein the skirt is formed in a polygonal shape by means of a series of sides. 7. The cap according to claim 6, wherein the ribs are divided annularly into first and second separate groups, wherein the first group of ribs contains a different number of ribs from the second group, andwherein one of the first or second groups of ribs projects from one of the sides. 8. The cap according to claim 3, wherein the ribs have an axial pattern. 9. The cap according to claim 8, wherein the ribs are parallel to each other. 10. The cap according to claim 3, wherein the ribs decrease in thickness axially, from a lower free edge towards an upper free edge of the skirt. 11. The cap according to claim 3, wherein the cap comprises angularly spaced tabs which extend radially to join the central body to the skirt. 12. The cap according to claim 11, wherein the ribs decrease in thickness axially, from the lower free edge towards the upper free edge of the skirt, andwherein the passage surmounts the central body, delimited by the upper free edge, wherein the at least one tooth is configured to engage the upper free edge. 13. The cap according to claim 12, wherein the at least one tooth has an inclined guide surface for insertion on the skirt. 14. The cap according to claim 1, comprising a guarantee seal. 15. The cap according to claim 1, made in a single piece in plastic material. 16. An assembly comprising a plurality of caps made according to claim 1, positioned alongside each other axially overlapping and attached to each other in a releasable manner. 17. The assembly according to claim 16, wherein a first passage defined by a first cap is in communication with second passage defined by a second cap. 18. A cap for a container, comprising: a central body extending along a central axis and having a cylindrical shape with a lower end that is open and a top that is closed by a base, the central body including internal threads configured to engage external threads on the neck of the container;an annular skirt that extends around the central axis to surround the central body and is radially spaced from the central body, the skirt including a continuous wall having a lower free edge adjacent to the lower end of the central body and an upper free edge adjacent to the base of the central body; anda plurality of tabs projecting radially outward from the central body and joining the central body to the skirt, wherein the skirt is radially spaced from the central body to form a passage open to passage of air at least by the skirt having a top surface with the upper free edge that defines the passage for the passage of air and the skirt has the lower free edge, at the lower end of the central body on the side opposite the base; anda plurality of teeth projecting axially from the tabs along the central axis of the central body in a direction away from the base of the central body, the teeth being configured to engage by interference with the upper free edge of a skirt of a similar cap to connect the two caps together.
