       6 ) A package as claimed in  claim 1 , wherein two projections ( 19 ) project outwards to engage the lid ( 4 ) with a given interference when the lid ( 4 ) is in the closed position.  
   
   
       7 ) A package as claimed in  claim 1 , wherein the container ( 2 ) comprises four longitudinal edges ( 14 ) defined between the lateral walls ( 8 ) and the front wall ( 7 ) and rear wall ( 6 ) of the container, and four transverse edges ( 15 ) defined between the bottom wall ( 9 ) and the lateral walls ( 8 ), front wall ( 7 ) and rear wall ( 6 ) of the container; and the lid ( 4 ) comprises four longitudinal edges ( 16 ) defined between the lateral walls ( 12 ) and the front wall ( 11 ) and rear wall ( 10 ) of the lid, and four transverse edges ( 17 ) defined between the top wall ( 13 ) and the lateral walls ( 12 ), front wall ( 11 ) and rear wall ( 10 ) of the lid.  
   
   
       8 ) A package as claimed in  claim 7 , wherein at least some of the longitudinal edges ( 14 ) of the container ( 2 ) and the corresponding longitudinal edges ( 16 ) of the lid ( 4 ) are rounded or bevelled.  
   
   
       9 ) A package as claimed in  claim 7 , wherein at least some of the transverse edges ( 15 ) of the container ( 2 ) or of the lid ( 4 ) are rounded or bevelled.  
   
   
       10 ) A package as claimed in  claim 1 , wherein the package ( 1 ) is formed from a flat blank ( 26 ) having two longitudinal fold lines ( 27 ), and a number of transverse fold lines ( 28 ) defining between the longitudinal fold lines ( 27 ) 
 a first panel ( 7 ′) forming the front wall ( 7 ) of the container ( 2 );    a second panel ( 9 ′) forming the bottom wall ( 9 ) of the container ( 2 );    a third panel ( 6 ′) forming the rear wall ( 6 ) of the container ( 2 );    a fourth panel ( 10 ′) forming the rear wall ( 10 ) of the lid ( 4 );    a fifth panel ( 13 ′) forming the top wall ( 13 ) of the lid ( 4 );    a sixth panel ( 11 ′) forming the front wall ( 11 ) of the lid ( 4 ); and    a first inner tab ( 29 ) for reinforcing the front wall ( 11 ) of the lid ( 4 ).
