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.

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 said cylindrical sleeve having a close end proximate to said first open end of said cylindrical sleeve and an open end at said second open end of said cylindrical sleeve;
- (c) a rod adapted to be arranged concentrically within said cylindrical sleeve having a first rod end and a second rod end, said first rod end being adapted to engage with said first open end of said cylindrical sleeve;
- and
- (d) a removable lock comprising a ring or cap proximate to and removably engaged with said second end of said cylindrical sleeve and locked there in a child-proof manner and blocking said open end of said longitudinal slit.
A method for enclosing a material in a child-proof pouch comprising the steps of:
- (a) providing a flexible pouch having a mouth at one end;
- (b) inserting said material into said pouch through said mouth;
- (c) providing a closure for said pouch comprising a cylindrical sleeve having a first open end and a second open end;
- a longitudinal slit in said cylindrical sleeve having a closed end proximate to the first open end of the cylindrical sleeve and an open end at the second open end of the cylindrical sleeve;
- a rod adapted to be arranged concentrically within the cylindrical sleeve, said rod having a first end and a second end, the first end of said rod being adapted to engage with the first end of said cylindrical sleeve;
- and a removable lock comprising a ring or cap proximate to and removably engaged with the second open end of said cylindrical sleeve or to the second end of said rod and blocking the open end of said longitudinal slit;
- (d) folding the end of said pouch comprising said mouth so that the walls of said pouch proximate said mouth form a channel;
- (e) aligning said channel so that said channel fits entirely within said cylindrical sleeve surrounding said rod;
- and
- (f) securing said lock to said second end of said cylindrical sleeve or to the second end of said rod, thereby sealing said pouch and enclosing said material therein.
