Capping assembly for receptacles

Abstract

The present invention belongs to the technical field of closures with discharge devices for receptacles, focusing on hinged closures. It consists of a capping assembly intended to be attached to the gland of a liquid container. This assembly consists of a tubular neck (1) and a cylindrical hinged cap (2). The cap integrates a ring (3) linked to the neck, a hinged lid (4) for opening and closing the pouring hole, a hinge (5) for hinging the cap and frangible bridges (16) between the ring and the cap. Additional elements in the tubular neck, such as a lower collar and an upper washer, contribute to the efficiency and functionality of the assembly.

1 . A capping assembly for receptacles, attachable to the gland of a liquid container receptacle, wherein the gland has a pouring orifice for liquid outlet, wherein the assembly comprises:
 a neck ( 1 ) consisting of a tubular body axially attachable to the gland of the receptacle; and   a substantially cylindrical hinged cap ( 2 ), attached to the neck ( 1 ), comprising:
 a ring ( 3 ) attached to the neck ( 1 ); 
 a hinged lid ( 4 ) for opening and closing the pouring hole; 
 a hinge ( 5 ) for hinging the lid ( 4 ) relative to the ring ( 3 ); and 
 frangible bridges ( 16 ) between the ring ( 3 ) and the lid ( 4 ); 
   the assembly being characterised in that the tubular body of the neck ( 1 ) comprises:   a lower collar ( 6 ), protruding radially outwards, for the lower stop of the ring ( 3 );   an upper locking washer ( 7 ), protruding radially outwards, for the upper stop of the ring ( 3 ); and   a cylindrical part ( 8 ) intermediate between the lower collar ( 6 ) and the upper washer ( 7 ), intended to face an inner side of the ring ( 3 ) of the cap, with a height (h), delimited between the lower collar ( 6 ) and the upper washer ( 7 ), having a value in the range from 3.3 mm to 4 mm, including the extreme values of this range.   
     
     
         2 . The capping assembly according to  claim 1  wherein the lid ( 4 ) comprises a flat, disc-shaped upper base ( 9 ) attached to a curved perimeter wall ( 10 ) extending downwardly from said upper base ( 9 ). 
     
     
         3 . The capping assembly according to  claim 2  wherein the perimeter wall ( 10 ) comprises a transverse visor ( 11 ). 
     
     
         4 . The capping assembly according to  claim 3  wherein the visor ( 11 ) comprises a transverse fin, corresponding to a complementary recess provided in the upper edge of the ring ( 3 ). 
     
     
         5 . The capping assembly according to  claim 4  wherein the flange comprises on the edge of its inner surface a bead transverse to the axial axis of the cap ( 2 ) for gripping the lid ( 4 ) to the neck ( 1 ). 
     
     
         6 . The capping assembly according to  claim 2  wherein the upper base ( 9 ) comprises a cylindrical skirt ( 12 ) emerging from its inner face. 
     
     
         7 . The capping assembly according to  claim 3  wherein the upper base ( 9 ) comprises a cylindrical skirt ( 12 ) emerging from its inner face. 
     
     
         8 . The capping assembly according to  claim 4  wherein the upper base ( 9 ) comprises a cylindrical skirt ( 12 ) emerging from its inner face.
