       3 . The covering device of  claim 1 , wherein the securing means comprises a belt for tightening the cover to the container around the opening. 
   
   
       4 . The covering device of  claim 1 , wherein the cover is adapted to be substantially upwardly extending, in an intermediate position. 
   
   
       5 . The covering device of  claim 1 , wherein the cover comprises a spacer for keeping the cover at a distance from a substance contained by the container or from the bottom of the container when the covering device is in the closed position. 
   
   
       6 . The covering device of  claim 1 , wherein the linkage is adapted for pulling the cover at a distance from a substance contained by the container or from the bottom of the container when the covering device is in the closed position. 
   
   
       7 . The covering device of  claim 1 , wherein the cover is permeable to a light for allowing the light to reach a substance contained by the container when the covering device is in the closed position. 
   
   
       8 . The covering device of  claim 1 , wherein the cover comprises at least one of a tissue, a fabric, a net, a web-like net, a fish net, a tarp and a plurality of hinged panels. 
   
   
       9 . The covering device of  claim 1 , wherein the cover comprises a solar receptor for receiving solar energy. 
   
   
       10 . The covering device of  claim 1 , wherein the support comprises a post closely located with respect to the container. 
   
   
       11 . The covering device of  claim 1 , wherein the support has a portion causing the connector to be above the opening. 
   
   
       12 . The covering device of  claim 1 , wherein the support comprises a movable portion on which the connector is mounted so that in the closed position the connector is above the opening and in the opened position the connector is away from the opening. 
   
   
       13 . The covering device of  claim 1 , wherein the linkage is versatile to have at least two different configurations, a closed configuration adapted for the closed position and an opened configuration adapted for the opened position. 
   
   
       14 . The covering device of  claim 1 , wherein the linkage comprises a flexible portion. 
   
   
       15 . The covering device of  claim 14 , wherein the connector comprises a pulley causing the linkage to be accessible by a user. 
   
   
       16 . The covering device of  claim 14 , further comprising an enclosing device for containing a portion of the linkage, and a locking means to lock the linkage in the enclosing device. 
   
   
       17 . The covering device of  claim 14 , further comprising a wheel for winding a portion of the linkage thereon and thereby adapting the linkage to the closed position and to the opened position. 
   
   
       18 . The covering device of  claim 17 , wherein the wheel comprises a motor system for winding the portion of the linkage around the wheel. 
   
   
       19 . The covering device of  claim 1 , further comprising a sensor for notifying tampering or contact with the cover in the closed position. 
   
   
       20 . The covering device of  claim 1 , wherein the support further comprises a fastener for fixing an additional accessory.
