Description

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention is related to a packing box, and more particularly to a packing box made up of plastic material.

[0003] 2. Description of Related Art

[0004] Referring to FIGS. 5 and 6, a conventional packing box generally made up of a plastic material is used for containing foods. The packing box is composed a container (44) integrated with a cover (40). The cover (40) is connected with the container (44) by a ridge (42) formed at a side between the container (44) and the cover (40). The cover (40) then can be turned about the ridge (42) to open or close the packing box. A first rim (41) is formed around the cover (40) and abuts a second rim (45) formed around the container (44) when the cover (40) is closed.

[0005] However, the conventional packing box has some disadvantages as following:

[0006] 1. For securely closing the packing box, the rims (41, 45) generally are fastened by staples and tightly abutted together. It is difficult and inconvenient for a user to open the box by pulling the rims (41, 45) or front corners (46), which leads to a possibility of fingers being hurt by edges of the rims (41, 45) or the front corners (46).

[0007] 2. The areas of the rims (41, 45) and the front corners (46) are so small that it is also difficult and inconvenient to practice the operation of closing the cover (40) and fastening the rims (41, 45).

[0008] Therefore, the invention provides an improved packing box to mitigate and/or obviate the aforementioned problems.

SUMMARY OF THE INVENTION

[0009] The main objective of the invention is to provide a packing box that has a cover and a container that are easily and safely connected to each other.

[0010] Other objects, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0017] Referring to FIG. 1, a packing box in accordance with the invention made up of a plastic material is composed of a cover (10) and a container (20). A ridge (30) is formed between the cover (10) and the container (20) to connect the cover (10) with the container (20).

[0018] Referring to FIGS. 2-4, the cover (10) has a cap (11) formed at a top thereof. A first step (13) is formed under the cap (11) and has an upper surface (131) and a wall (132) perpendicular to the upper surface (131). A first rim (16) is formed around the first step (13) and has two first triangular portions (17) respectively formed at two corners thereof opposite to the ridge (30). Two bent edges (171) are respectively formed between the triangular portions (17) and the first rim (16).

[0019] Two notches (12) are respectively defined in the cap (11) at the two corners to form two pressed portions (14) on the upper surface (131). Users can locate their fingers such as thumbs at the respective pressed portions (14) to press down the cover (10) for closing the box. Two stops (15) are respectively formed in the first step (11) at the corners and protruded inwards on the wall (132).

[0020] The container (20) has a second step (21) formed thereon and corresponding to the first step (13). A second rim (24) is formed around the second step (21). Two recesses (23) are respectively defined in the second step (21) at the corners for receiving the corresponding stops (15) therein. Each of the recesses (23) has an upper edge (22) for preventing the stop (15) from easily escaping from the recess (23).

[0021] Two second triangular portions (25) are respectively formed on the second rim (24) and corresponding to the first triangular portions (17). The second triangular portions (25) each have a semi-spherical lug (26) formed at an upper surface thereof. The triangular portions (17, 25) have patterns formed thereon for increasing grip by a user.

[0022] When closing the box, a user can press the pressed portions (14) by fingers to move the cover (10) down, and the stops (15) are positioned in the recesses (23) to securely fasten the cover (10) on the container (20). The first triangular portions (17) are spaced apart from the second triangular portions (25) because of the semi-spherical lugs (26).

[0023] When the user opens the packing box, the fingers can insert in gaps between the first triangular portions (17) and the second triangular portions (25) to pull up the cover (10). At the same time, the stops (15) are disengaged from the recesses (23). Thus, the packing box is opened.

[0024] From the above description, it is noted that the invention has the following advantages:

[0025] 1. There are two pressed portions formed on the first steps that have a large area for being pressed by fingers, so that it is very convenient to close the packing box.

[0026] 2. Because of the lugs, there are gaps between the first and second triangular portions, and it is also convenient for a user to open the box by inserting fingers in the gaps.

[0027] 3. By the stops being engaged in the recesses, the packing box is securely and tightly closed.

[0028] It is to be understood, however, that even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
