7. A package as claimed in claim 1 , and comprising a rigid collar ( 17 ) that projects partly from the open end ( 7 ) of the outer container ( 2 ), is folded about the inner package ( 3 ) to at least partly cover a top portion of the inner package ( 3 ), and is fixed to the inner package ( 3 ); the reclosable sealing panel ( 6 ) is located over the collar ( 17 ), and has an inner surface ( 21 ) gummed with non-dry, re-stick adhesive, and which adheres to the collar ( 17 ) when the reclosable sealing panel ( 6 ) is in a closed position.

8. A package as claimed in claim 7 , wherein:

the reclosable sealing panel ( 6 ) is fixed permanently at a rear wall of the inner package ( 3 ); the collar ( 17 ) has no rear wall, and the reclosable sealing panel ( 6 ) is fixed permanently and directly to the rear wall of the inner package ( 3 ).

9. A package as claimed in claim 7 , wherein:

the reclosable sealing panel ( 6 ) is fixed permanently at a rear wall of the inner package ( 3 ); the collar ( 17 ) comprises a rear wall that partly covers the rear wall of the inner package ( 3 ), and the reclosable sealing panel ( 6 ) is fixed permanently to the rear wall of the collar ( 17 ).

10. A rigid package comprising:

a group ( 4 ) of articles;

an inner package ( 3 ) enclosing the group ( 4 ) of articles and having an extraction opening ( 5 );

a reclosable sealing panel ( 6 ), which closes the extraction opening ( 5 ) of the inner package ( 3 ), and has an inner surface ( 21 ) gummed with non-dry, re-stick adhesive, and a grip tab ( 25 ) with no re-stick adhesive; and

the package ( 1 ) being characterized in that the grip tab ( 25 ) has a first closed configuration, in which the grip tab ( 25 ) is folded 180° onto an outer surface of the sealing panel ( 6 ), so as not to project from the lid ( 8 ) when the lid ( 8 ) is in the closed position closing the open end ( 7 ) and is maintained in the closed configuration by the lid ( 8 ) in the closed position closing the open end ( 7 ); and the grip tab ( 25 ) has a second, subsequent open configuration in which the grip tab ( 25 ) is not coplanar with the sealing panel ( 6 ) so as to be grippable.

11. A packing method for producing a rigid package; the packing method comprising the steps of:

forming an extraction opening ( 5 ) in a sheet ( 35 ) of packing material;

folding the sheet ( 35 ) of packing material about a group ( 4 ) of articles to form an inner package ( 3 ) that encloses the group ( 4 ) of articles and has the extraction opening ( 5 );

applying a reclosable sealing panel ( 6 ), which closes the extraction opening ( 5 ) of the inner package ( 3 ), and has an inner surface ( 21 ) gummed with non-dry, re-stick adhesive, and a grip tab ( 25 ) with no re-stick adhesive; and

folding a blank ( 51 ) about the inner package ( 3 ) to form a rigid outer container ( 2 ), which houses the inner package ( 3 ), and has an open end ( 7 ), and a lid ( 8 ) hinged to rotate between an open position and a closed position opening and closing the open end ( 7 ) respectively;

the packing method being characterized by comprising the further steps of:

before the parts ( 12 ′, 14 ′) of the blank ( 51 ) forming the lid ( 8 ) are completely folded, folding the grip tab ( 25 ) 180° with respect to the rest of the sealing panel ( 6 ) into a first closed configuration, in which the grip tab ( 25 ) is folded 180° onto an outer surface of the sealing panel ( 6 ), so as not to project from the lid ( 8 ) when the lid ( 8 ) is in the closed position closing the open end ( 7 ); and

folding the parts ( 12 ′, 14 ′) of the blank ( 51 ) forming the lid ( 8 ) over the grip tab ( 25 ) in the closed configuration, so the lid ( 8 ) in the closed position closing the open end ( 7 ) keeps the grip tab ( 25 ) in the closed configuration.

12. A packing method as claimed in claim 11 , and comprising the further steps of:

keeping the grip tab ( 25 ) in the closed configuration by means of a thin first folding device ( 64 ) which presses on the grip tab ( 25 );

folding a first part ( 12 ′) of the blank ( 51 ) forming the lid ( 8 ) over the grip tab ( 25 ) and the thin first folding device by means of a second folding device ( 65 ); and

withdrawing the thin first folding device ( 64 ) from the first part ( 12 ′) of the blank ( 51 ) before completely folding a second part ( 14 ′) of the blank ( 51 ) forming the lid ( 8 ).
