1. A protector for a drink opening in a liquid container comprising, a removable closure for the opening in the container, a flat cover having a plurality of small apertures therein and a peripheral portion surrounding the apertures, mounting means comprising an adhesive located on said peripheral portion for mounting the cover to the container, a releasable mounting area located on the container where the cover is initially mounted prior to removal of the closure whereby after removal of the closure the cover is removed from said mounting area and adhesively attached about the exterior periphery of the opening of the container so that dangerous insects and the like are prevented from entering the container through the drink opening by said cover but the liquid in the container is capable of passing through said cover. 2. A protector as claimed in claim 1 wherein said cover includes a tab portion projecting outwardly from the edge of said cover to facilitate removal of said cover from said mounting area. 3. A protector for a drink opening in a liquid container comprising, a tab opening device including a tab actuator and a shearable closure which is displaced by the tab actuator to expose the can opening, the tab actuator having a portion thereof including a flat cover having a plurality of samll apertures therein, mounting means for mounting said cover to the container over the drink opening, said mounting means including a locking means for locking said flat cover in position over the opening whereby dangerous inserts and the like are prevented from entering the container through the drink opening by said cover but the liquid in the container is capable of passing through said cover. 4. A protector as claimed in claim 3 wherein the tab actuator is elongated and is attached adjacent one end to the can by a rivet to act as a lever about the rivet to push the shearable closure into the can interior, and wherein said locking means includes a respective lock member located on each lateral side of said flat cover which engage a respective lateral side of the can opening to hold said flat cover in place. 5. A protector as claimed in claim 4 wherein the tab actuator is rotated about the rivet parallel to the plane of the can opening to bring said flat cover adjacent the can opening, and wherein said lock members are flanges which are located underneath respect lateral edges of the can opening to lock said flat cover in position over the can opening. 6. A protector as claimed in claim 4 wherein the tab actuator is pivoted about the attachment to the rivet having an axis parallel to the plane of the can opening, and wherein said lock members are catch means resiliently mounted on respective lateral sides of said flat cover for catching under respective lateral edges of the can opening to lock said flat cover in position over the can opening. 7. A protector as claimed in claim 6 wherein said plurality of small apertures are slots which are formed from a large aperture in said flat cover and a plurality of fingers which are integrally formed with said flat cover and which extend across said large aperture in a parallel, spaced relationship. 8. A protector as claimed in claim 7 wherein said fingers extend laterally away from said flat cover and are bent back across said large aperture to form said slots. 9. A protector as claimed in claim 3 wherein the tab actuator is removable from the can together with the shearable closure which is attached at one end to the tab actuator, and wherein said mounting means includes the shearable closure and a flange extending longitudinally from said flat cover on the opposite side of said flat cover from the shearable closure whereby said flat cover is locked over the can opening by locating the shearable closure underneath one edge of the can opening and said flange underneath an opposite edge of the can opening. 10. A protector as claime claim 9 wherein said plurality of small apertures are slots formed in said flat cover.
