The present invention relates to a container and more particularly to a container with discernible function when opened by intentional person.
The traditional plastic lunch box, including a lid and a box body, mainly use the box body to contain food, and then sealed through the lid. The lid comprises a top portion, and a side part extending from the outer edges of the top portion to the direction of the box body. The side part is adapted to cover around the upper end of the box body, and the lid is fixed on the box body to achieve the sealing effect.
However, the conventional container has following disadvantages: the lid covers the box body only through the side part, although the engaging point design on the side wall of the box body can be fixed with the lid, when the box body or the lid is pressed to be deformed, the engaging point may be failed to lose the sealing effect of the container, leading to the food inside the box spilled out. Also, the engaging point design allows the lid to be repeatedly closed and opened, so that it is difficult for consumers to tell whether the lid has been opened by intentional persons, so as to cause risk. Therefore, there remains a need for a new and improved design for a container to overcome the problems presented above.
The present invention provides a main body, and a lid is adapted to couple on the main body. The main body has a first peripheral edge on the outer periphery of an upper opening of the main body, and at least two first coupling portions are respectively and horizontally extended outward from the first peripheral edge at the symmetrical positions. Each of the first coupling portions comprises a connecting plane, and a connecting protrude is formed at the center portion of the connecting plane. Each of the locating arc surfaces is formed on the outer vertical surface of the first peripheral edge at the position aligned with the connecting plane. Each of first hinge portions is extended from the outer edge of the connecting plane of the first coupling portion, and each of first bending portions is formed between the first hinge portion and the first coupling portion so as to allow the first hinge portion to be folded toward the connecting plane. Each of the first hinge portions has a connecting recess formed thereon, and the connecting recess is engaged and secured with the connecting protrude, and the periphery of the connecting recess comprises a broken line. The outer periphery of the lid comprises a second peripheral edge, and the inner side of the second peripheral edge is configured to couple with and cover the first peripheral edge of the main body. At least two first cover portions respectively protrude outwardly from the periphery of the second peripheral edge at the symmetrical positions, and the first cover portions respectively cover and couple with the first coupling portions. Each of the first cover portions comprises a cover plane, and the cover plane is adapted to be coupled and positioned on the connecting plane. Each of concaved curved surfaces is formed on the outer vertical surface of the second peripheral edge at the position aligned with the cover plane. Each of the cover planes has a through hole thereon, and each of the connecting protrude is adapted to pass through the through hole. The diameter of the through hole is larger than the diameter of the broken line of the connecting recess.
In one embodiment, each of two lateral sides of the connecting plane has a locating protrude, and the positions of the two locating protrudes are higher than the connecting plane, and each of the locating protrudes is connected to the connecting plane through a first oblique plane.
In another embodiment, each of two lateral sides of the cover plane has a shell portion, and the positions of the shell portions are higher than the cover plane, and each of the shell portions is connected to the cover plane through a second oblique plane.
In still another embodiment, the connecting protrude is formed in a conical cylinder shape, and the connecting recess is formed in a tapered shape so as to tightly engage with the connecting protrude.
In a further embodiment, the first peripheral edge of the main body comprises at least two protruded second coupling portions at the symmetrical positions, and each of the second coupling portions has a second hinge portion on the outer edge thereof; each of second bending portions is formed between the second hinge portion and the second coupling portion, and each of the second coupling portions has a coupling protrude formed at the center portion of the second coupling portion, and each of two lateral sides of the coupling protrude comprises a coupling recess; each of the second hinge portions has a first engaging portion protruding from the surface thereof, and the second peripheral edge of the lid has at least two protruded second cover portions at the symmetrical positions, and the second cover portions are respectively coupled with and cover the second coupling portions; each of the second cover portions has an engaging protrude formed at the center portion thereof, and each of two lateral sides of the engaging protrude has a locating recess; the engaging protrude is hollow inside and correspondingly covers the outer side of the coupling protrude, and the locating recesses are respectively coupled with the coupling recesses to complete positioning.
Comparing with conventional container, the present invention is advantageous because: with the designs of the connecting recess and the broken line, when the lid is coupled on the main body, the user can pull and detach the first hinge portion from the cover plane to enable the lid to be openable, and the connecting recess is split free from the broken line to make the first hinge portion to be not engaged with the lid again, so that the user can easily identify whether the lid is opened, so as to improve the protection effect of the container.
