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.
BRIEF DESCRIPTION OF THE DRAWINGS
[0011] FIG. 1 is a perspective view of a packing box in accordance
with the invention;
[0012] FIG. 2 is an enlarged partially perspective view of the
packing box in FIG. 1, wherein a cover is spaced from a
container;
[0013] FIG. 3 is an enlarged partially perspective view of the
packing box in FIG. 1, wherein the cover is abutted the
container;
[0014] FIG. 4 is a side view showing an open/close action of the
packing box in accordance with the invention;
[0015] FIG. 5 is a perspective view of a conventional packing box;
and
[0016] FIG. 6 is a side view showing an open/close action of the
conventional packing box.
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.
