Description
TECHNICAL FIELD
[0001] The invention relates to an expanded polyproplene (EPP) box,
and more particularly to an EPP box for loading and transporting
liquid crystal display (LCD) panels.
BACKGROUND
[0002] At present, LCD panels are mainly loaded and transported by
EPP boxes. LCD panels are vertically or horizontally put in a box
body with or without a top cover. LCD panels are expensive and thus
should be protected especially during the transportation. Thus, it
is important to control the inner length and width of the box body
of an EPP box no matter whether the LCD panels are vertically or
horizontally put in the EPP box. If the inner length and width of
the box body are much larger than those of the LCD panel, the LCD
panel will shake in the box body during the transportation and the
LCD panel impacts the inside of the box body, easily resulting in
the b of the LCD panel. If the inner length and width of the box
body are smaller than or equal to those of the LCD panel,
considering the dimensional tolerance of the box body and the
dimensional tolerance of the panel in the process of production,
the panel may not be put in the box body. Even if the panel is put
in the box body, the sides or corners thereof easily collide with
the box body, thereby causing fragmentation. The box body of the
existing EPP box is formed by an integrated mold, namely the box
bottom of the EPP box and the frame thereon are integrally formed
and can not be disassembled. This type of structure of the box body
does not facilitate to control and regulate the inside dimension of
the box body. The manufacturer of the existing EPP box controls the
inside dimension of the EPP box mainly by adding some positioning
devices after molding and before entering a baking room. However,
disadvantages occur, such as the selection of the positioning
devices, the usage amount of the material, and insufficient baking
room space because a large space is occupied after the whole box
body in which the positioning devices are added is put in a baking
room during baking. In addition, because the box body of the
existing EPP box is integrated, if part of the box body is damaged
while in use, the box body is difficult to maintain and has to be
discarded, thereby increasing the production cost.
SUMMARY
[0003] The aim of the invention is to provide an EPP box with
advantages of easy control of the inside dimension of the box body,
easy maintenance of the box body and production cost saving.
[0004] To solve the aforementioned technical problems, the
invention provides an EPP box comprising a box bottom and a
plurality of side walls removably arranged on the box bottom,
wherein the plurality of side walls are connected pairwise to form
a removable frame.
[0005] Preferably, the box bottom is provided with a plurality of
clip holes, and the bottom of the frame is formed with a plurality
of clip tenons for clamping the clip holes.
[0006] Preferably, the plurality of the side walls is four in
number and comprises two first side walls arranged oppositely and

DETAILED DESCRIPTION
[0021] The technology, the structural feature, and the aim and
effect achieved of the invention will be described in detail in
accordance with the specific examples and the figures.
[0022] As shown in FIG. 1, in a first preferred example of an EPP
box of the invention, the EPP box 100 comprises a box bottom 10 and
a plurality of side walls removably arranged at the box bottom 10;
the plurality of side walls are connected pairwise to form a
removable frame 30.
[0023] The box bottom 10 is of a plate. The plate can be a
rectangular plate, circular plate, or plate and the like in
accordance with the requirement of components to be assembled. In
the first preferred example, the box bottom 10 is a rectangular
plate. The panel surface of the box bottom 10 close to the
periphery thereof is provided with a plurality of clip holes 12. In
the first example, the four corners of the rectangular plate are
provided with one clip hole 12, and all the sides of the
rectangular plate are provided with at least one clip hole 12.
[0024] The plurality of side walls may be different in length. In
the first preferred example, the side walls are four in number and
comprise two first side walls 22 arranged oppositely and two second
side walls 24 arranged oppositely. Each first side wall 22 is
formed with a first clip tenon 222 and a first clip hole 224. The
first clip tenon 222 is formed on the bottom of the first side wall
22 for clamping the corresponding clip hole 12 in the box bottom
10. The first clip hole 224 faces the second side wall 24 for
clamping the second side wall 24. Each second side wall 24 is
formed with second clip tenon(s) 242 and third clip tenon(s) 244,
and the second clip tenon 242 is formed on the bottom of the second
side wall 24 for clamping the corresponding clip hole 12 in the box
bottom 10. The third clip tenons 244 are respectively formed on
both ends of the second side wall 24 and face each first side wall
22, respectively, for clamping the corresponding first clip holes
224 in the first side wall 22.
[0025] As shown in FIG. 1 to FIG. 3, when the EPP box 100 is
assembled, the third clip tenons at one end of the second side wall
24 are respectively clamped in the first clip holes 224 in the same
side of one first side wall 22, and the third clip tenons 244 at
the other end of the second side wall 24 are respectively clamped
in the first clip holes 224 of the other first side wall 22. Thus,
the first side walls 22 and the second side walls 24 are connected
to form the frame 30. Then, the frame 30 and the box bottom 10 are
assembled, and the first clip tenons 222 of the first side walls 22
and the second clip tenons 242 of the second side walls 24 are
respectively and correspondingly clamped in the clip holes 12 in
the box bottom 10. Therefore, the EPP box 100 is assembled.
[0026] Because the first side wall 22 and the second side wall 24,
the first side wall 22 and the box bottom 10, and the second side
wall 24 and the box bottom 10 are connected by clips, the EPP box
is conveniently disassembled. In the first preferred example, the
frame 30 is formed by four side walls. One of ordinary skilled in
the art can understand that the four side walls can be single
structures respectively, the structures can be different, and the
two opposite side walls can be of dissymmetrical structure; the
four side walls can be of two symmetrical structures, and thus only
two set of mold is required to be developed when making the side
walls. If the four side walls are of the same structure, only a set
of mold is required to be developed when making the side walls. In
the first preferred example, the side walls are of two symmetrical
structures. The box bottom and the side wall or the adjacent side
walls themselves are connected by clips, namely one is provided
with clip tenons and the other is correspondingly provided with
clip holes. The structure of the clip tenons can be various, for
example, the structure of the clip tenons can be cylinder, or
stereo fillet, or swallowtail butterfly. Each clip hole should be
of a structure matching with the structure of the clip tenon. The
positions of the clip tenons and the clip holes can be exchanged;
if the first side wall 22 is connected with the second side wall
24, the first side wall 22 is provided with second clip tenons 242,
thus the second side wall 24 should be correspondingly provided
with first clip holes 224.
[0027] As shown in FIG. 4, in a second preferred example of an EPP
box of the invention, the structure of the EPP box 200 is
approximately the same as that of the EPP box 100. The structure of
the EPP box 200 is different from that of the EPP box 100 in that:
in the second preferred example, the EPP box 200 further comprises
a box cover 40, to ensure the box cover 40 is stably covered on the
frame 30. The top surfaces of the first side wall 22 and the second
side wall 24 are respectively formed with flanges 32, and the
bottom of the box cover 40 is correspondingly provided with grooves
(not shown in the figure) to match with the flanges 32. By covering
the box cover 40 on the frame 30, the components arranged in the
frame 30 can be further protected. Thus, the box cover 40 plays a
role of fixation and dust prevention. Understandably, the bottom of
the box cover 40 can be formed with flange(s), and the top surface
of the frame 30 can be correspondingly provided with groove(s).
[0028] As shown in FIG. 5, in a third preferred example of an EPP
box of the invention, the structure of the EPP box 300 is
approximately the same as that of the EPP box 200. The structure of
the EPP box 300 is different from that of the EPP box 200 in that:
the frame 30 is only composed of two symmetrical side walls 52.
Thus, only a set of mold is required to be developed when making
the side walls, thereby greatly saving the manufacturing cost.
[0029] To sum up, the EPP box of the invention is provided with a
plurality of side walls, the plurality of side walls are removably
connected to form the frame for arranging components such as LCD
panels. The dimension of each side wall is accurately controlled by
individually making the side walls, and the internal dimension of
the frame is easily controlled and regulated. In addition, only the
damaged side wall(s) is replaced when part of the EPP box is
damaged while in use without discarding the whole box body, the box
body is easily maintained, and the production cost is greatly
reduced.
[0030] The invention is described in detail in accordance with the
above contents with the specific preferred examples. However, the
invention is not limited to the examples. All the equivalent
structure changes or equivalent process changes which are made by
using the contents of the specification and the figures of
specification of the invention, or directly or indirectly used in
other relevant technical fields should be considered to belong to
the patent protection scope of the invention.
