Abstract
A closure for a pouch comprising: (a) a cylindrical sleeve having a first open end and a second open end, (b) a longitudinal slit in the cylindrical sleeve having a close end proximate to the first end of the cylindrical sleeve and an open end at the second end of the cylindrical sleeve; (c) a rod adapted to be arranged concentrically within the cylindrical sleeve having a first end and a second end, the first end of the rod being adapted to engage with the first end of the cylindrical sleeve; and (d) a child-proof lock adapted to be removably connected to the second end of the cylindrical sleeve or to the second end of the rod to block the open end of the longitudinal slit.

Closure (10) for a pouch (30) comprising:
- a cylindrical sleeve (12) having a first open end (14) and a second open end (16);
- a longitudinal slit (18) in the cylindrical sleeve (12) having a close end (20) proximate to the first end (114) of the cylindrical sleeve (12) and an open end at the second end (16) of the cylindrical sleeve (12);
- a rod (22) adapted to be arranged concentrically within the cylindrical sleeve (12) having a first end (24) and a second end (26), the first end (24) of the rod (22) being adapted to engage with the first end (14) of the cylindrical sleeve (12);
- and
- a lock adapted to be removable connected to end portion (40) proximate the second end (16) of the cylindrical sleeve (12) or to the second end (26) of the rod (22) to block the open end of the longitudinal slit (18).
