A locking mechanism for container and lid thereof comprising a container and a lid;
- wherein the container has a first periphery edge has the peripheral edge of the upper opening thereof, and at least two first coupling portions, which are located at symmetric positions, and at least two second coupling portions, which are located at symmetric positions, outwardly protrude from the first periphery edge respectively;
- an outer edge of each of the first coupling portion has a first hinge portion, and a first bending portion is formed between each of the first coupling portion and the first hinge portion;
- the first hinge portion comprises a second engaging protrude on a surface thereof, and a first cutting broken line is formed on the first hinge portion around the outer periphery of the second engaging protrude;
- each of the second coupling portions has a second hinge portion formed at the outer edge thereof, and a second bending portion is formed between the second coupling portion and the second hinge portion;
- each of the second coupling portions comprises a coupling protrude at the middle section thereof, and two coupling recesses are respectively formed at two lateral sides of the coupling protrude;
- each of the second hinge portions has a first engaging portion protruding from the surface thereof, and a first engaging recess is formed on an inner surface of the first engaging portion at the position corresponding to the coupling protrude, and two abutting surfaces are formed at two lateral ends of the first engaging recess respectively;
- a second engaging portion extended from the top of the first engaging portion is formed in parallel with the bottom of the first engaging recess;
- and
- wherein the lid comprises a second peripheral edge at the outer periphery thereof, and an inner surface of the second peripheral edge is configured to couple with and cover the first peripheral edge of the container;
- at least two first connecting portions respectively protrude from the second peripheral edge at symmetric positions, and at least two second connecting portions, which are located at symmetric positions, outwardly protrude from the second periphery edge respectively;
- the first connecting portions and the second connecting portions are adapted to be coupled with the first coupling portions and the second coupling portions respectively so as to complete positioning;
- a second engaging recess is formed on the surface of the first connecting portion, and the second engaging protrude of the first hinge portion is configured to engage with the second engaging recess, and the second engaging protrude is adapted to be separated through the first cutting broken line;
- when the first hinge portion is pulled down to detach from the first connecting portion of the lid, the second engaging protrude is separated from the first hinge portion through the first cutting broken line, and the second engaging protrude and the second engaging recess are still engaged together;
- each of the second connecting portions has a fourth engaging protrude at the middle section thereof, and two locating recesses are respectively formed at two lateral sides of the fourth engaging protrude;
- each of the fourth engaging protrudes is formed in a hollow shape to cover the coupling protrude, and the two locating recesses are positioned in the two coupling recesses respectively;
- each of the fourth engaging protrudes has a third coupling portion upwardly extending from the top and along the outside surface of fourth engaging protrude, and each of first recesses is formed between the third coupling portion and the second peripheral edge.
