A pouring device for a carton comprises a ring (9) sealed round a carton wall part (26) almost encircled by a loop of weakness (7), a tubular pouring spout (12) encircled by the ring (9) and connected thereto by frangible bridges (13), and a closure cap (33) spaced from the ring (9) by spacing strips (37) connected by frangible bridges (36) to the cap (33) and received in straight grooves (38) in the ring (9). Turning of the cap (33) about its own axis breaks the bridges (36), to cause the strips (37) to fall away. Then the cap (33) can be pushed inwards linearly axially relative to the ring (9) to break the bridges (13) and cause the spout (12) to break open the part (26), screwthreading (31) on the cap (33) riding over screwthreading (30) on the spout (12) into a co-operating condition, and an annular land (41) on the spout (12) riding past an annular flange (11) on the ring (9). In an alternative version, the cap is a flip cap hinged to the outer end of the pouring spout and the spacing strips are attached by frangible bridges to the spout. |
