A package is equipped with an opening and closing device (1) comprising a body (2) in a single piece, made of molded material, fixed on the wall (15), this body (2) comprising a plate (20) fitted with a hole (30) placed opposite the orifice (13) and fixed on the edge (19) of the orifice (13) of the wall (15) in a leaktight manner, and a door (40) articulated to this plate (20) opening towards the interior of the package and capable of blocking this hole (30) in a leaktight manner, and in that it further comprises an arm (50) connected to the door (40), the arm (50) cooperating with blocking means in a position such that it keeps the door (40) in a leaktight blocking position, and releasing the door (40) in pivoting towards the interior of the package when it is disengaged from the blocking means, and in that it further comprises a cover (80) distinct from the body (2) and from the arm (50), and which is fitted with a safety disc (100, 104) which must be broken during initial opening of the door (40), such that if the safety disc is intact, it is guaranteed that the package has never been opened previously, the disc forming part of the blocking means. ## Claims ### Claim 1 A package of consumable product provided with a substantially plane wall and fitted with an orifice, comprising: an opening and closing device comprising a body in a single piece, made of moulded material, fixed on said wall, said body comprising a plate fitted with a hole placed opposite said orifice, supported essentially on an inner face of said wall, and fixed on an edge of said orifice of the wall in a leaktight manner, and a door articulated to this plate opening towards the interior of the package and capable of blocking this hole in a leaktight manner, an arm connected to said door, said arm cooperating with blocking means in a first position such that it keeps said door in a leaktight blocking position, and releasing said door by pivoting towards the interior of said package when it is disengaged from said blocking means, and a cover distinct from said body and of said arm, and which is fitted with a safety disc which must be broken during initial opening of said door, such that if said safety disc is intact, it is guaranteed that the package has never been opened previously, said disc forming part of said blocking means; wherein said cover comprises means for connecting with said plate, said cover, when it is connected to said plate, being located outside said package such that a region of said wall is sandwiched between said cover and said plate. ### Claim 2 (depends on 1) The package as claimed in claim 1, wherein said plate is fixed on the edge of said orifice of the wall by snap-locking. ### Claim 3 (depends on 2) The package as claimed in claim 2, wherein said plate comprises first tabs or a snap-lock bead which snap-lock on the edge of said orifice of the wall. ### Claim 4 (depends on 1) The package as claimed in claim 1, wherein said plate comprises a first joint on which said door is supported such that the junction a junction between said door and said plate is leaktight. ### Claim 5 (depends on 1) The package as claimed in claim 1, wherein said plate comprises a second joint on which said inner face is supported such that a junction between said wall and said plate is leaktight. ### Claim 6 (depends on 5) The package as claimed in claim 5, wherein said second joint is a joint in ring form comprising two lips capable of acting as a suction cup against said inner face. ### Claim 7 (depends on 1) The package as claimed in claim 1, wherein the means for connecting are tabs which extend from said cover and are capable of snap-locking with second tabs of the plate by means of teeth located at an end of said tabs and of said second tabs. ### Claim 8 (depends on 3) The package as claimed in claim 3, wherein the means for connecting are tabs which extend from said cover and are capable of snap-locking with said snap-lock bead by means of grooves located at an end of said tabs and a second bead located at the end of said snap-lock bead, said snap-lock bead also comprising first beads serving as snap-locking with said wall. ### Claim 9 (depends on 1) The package as claimed in claim 1, wherein said blocking means of said arm in a position where said door is in a leaktight blocking position are connected to said cover. ### Claim 10 (depends on 9) The package as claimed in claim 9 wherein said blocking means further comprise serrations connected to said cover and repositioning said arm and said door in a leaktight blocking position. ### Claim 11 (depends on 1) The package as claimed in claim 1, wherein said cover has a U-shape, and said arm is folded back against the wall, in a central region of said U, when it is in a blocking position. ### Claim 12 (depends on 11) The package as claimed in claim 11 wherein said safety disc comprises a tongue fully covering the U-shaped central region of said cover, and links connecting said tongue and said cover. ### Claim 13 (depends on 1) The package as claimed in claim 1, said arm further cooperating with said blocking means in a second position such that said door is in the open position. ### Claim 14 (depends on 1) The package as claimed in claim 1, wherein said door and said plate are articulated to each other by a supple moulded web forming a hinge.
