[0027] Hereinafter, the thought of the present invention will be
clearly explained through the detailed description with reference
to the drawings.
[0028] An expanded planar diagram as shown in FIG. 3, the dash-dot
line "- - -" represents a mountain fold line, wherein the portions
at both sides of the mountain fold line are folded to be convex
outwards, thereby protruding the mountain fold line; a dash line "-
- - - - -" represents a valley fold line, wherein the portions at
both sides of the valley fold line are folded to be concave
inwards, thereby recessing the valley fold line; a dot line " . . .
" is used as a hinge of a door plate for opening a buffer space
formed by folding, wherein the buffer space is used for receiving
small articles. Accordingly, the expanded planar diagram shown in
FIG. 3 can be folded to form a box body as shown in FIG. 4, FIG. 5,
or FIG. 6, and there is no specific limitation to the folding
steps. The oblique lines shown in FIG. 3 are merely used for
clearly showing the configuration and empty portions in the
diagram, and do not intend to limit the paper material orientation
or any other items.
[0029] Concretely speaking, a thin sheet of paper material is first
used to form the pattern shown in FIG. 3, and the forming method
thereby is not specifically limited, for example, conventional
methods such as mold pressing, cutting, etc, can be adopted. The
thin sheet of paper material itself is not particularly limited, as
long as the material has a specific strength, foldable and not
being damaged easily. The thin sheet of paper material can be made
of single-layer or multiple-layer of corrugated paper, carton paper
or plastic or metal sheet. In view of the processing and
environmental protection, corrugated paper is preferred.
[0030] The pattern shown by FIG. 3 comprises a bottom plate 100; a
front plate 200 connected to the upper side of the bottom plate 100
as a front wall; side plates 300 connected to the left and right
sides of the bottom plate 100 as side walls; a rear plate 400
connected to the lower side of the bottom plate 100 as a rear wall;
a cover plate 500 extending upwards; and inner partition plates 600
which are connected to the respective side plates 300 and extend
towards the left and right.
[0031] The front plate 200 comprises side enhancing plates 210
connected to the left and right sides of the front plate 200. After

and right sides of the bottom plate 100.
[0032] The rear plate 400 comprises side enhancing plates 410 to
two opposite sides of the rear plate 400. As shown in FIG. 6, after
folding the rear plate 400 in accordance with the aforementioned
mountain and valley fold lines, two buffer spaces arranged in a
front-to-rear sequence are formed, and the enhancing plates 410
stands on two opposite sides of the rear buffer space for not only
enhancing the sides of the rear buffer space but also closing the
openings at the sides thereof. For sufficiently taking advantage of
these two buffer spaces, the rear plate 400 comprises an opening
420 and door plates 430, 440 and 450. The opening 420 and the door
plates 430, 440 and 450 are disposed at the proper positions by

aforementioned side enhancing plate 210 and front plate 200 is
provided with a corresponding tongue plate 220. The tongue plate
220 is inserted into the slot 480, thereby fixing the relative
positions between the front plate 200 and one portions of the rear
plate 400.
[0033] After being folded, the side plates 300 cover the side
enhancing plates 410, the side enhancing plates 210 and the
enhancing plates 470 to form buffer spaces 390. Further, support
plates 110 are formed respectively between the bottom plate 100 and
the two side plates 300. In this embodiment, the support plates 110
are consecutively formed between the respective bottom plates 100
and side plates 300. After being folded along the fold lines shown
in FIG. 3, the support plates 110 are lifted towards the bottom of
the bottom plate 100 so as to suspend the bottom plate 100 for
forming a buffer space below the bottom plate 100.
[0034] After being folded, the partition plates 600 extended from
the respective side plates 300 are located at the inner edges of
the box structure, i.e. the inner edges where the partition plates
600 are located divide a internal space, which is come from a frame
body formed by the front plate 200, the rear plate 400 and the two
side plates 300, into the upper and lower levels. For fixing the
positions of the partition plates 600, it is desirable to provide
protrusive plates 610 and corresponding slots 260 (and 460) on the
proper positions of the upper and lower edges of the partition
plates 600 and on the inner edges of the front plate 200 (and rear
plate 400), respectively. thereby fixing the positions of the
partition plates 600 via the engagements of the protrusive plates
610 and the slots 260 (and 460). For maintaining the engagements of
the protrusive plates 610 and the slots 260 and 460 at a
predetermined strength but also allowing the engagements thereof to
be released easily, the extension length of each protrusive plate
610 is preferably about equal to the thickness of the thin sheet
material.
[0035] As shown in FIG. 5 and FIG. 6, after being folded, the cover
500 covers the buffer spaces formed by the bottom plate 100 and the
rear plate 400, and thereafter covers the top of the box structure,
thereby closing the box structure. A tongue plate 520 is connected
to the upper edge of the cover plate 500, and a slot 250 is
provided on the corresponding position of the front plate 200, so

computer can be received between the bottom plate 100 or 101 and
the partition plates 600 or 601; a thinner user manual can be
placed into the space above the partition plates 600 or 601; the
buffer spaces formed by the rear plate 400 or 401 and the side
plates 300 or 301 can be used to accommodate smaller accessories
such as a transformer, a earphone and a mouse, etc.; and the buffer
space formed between the lower surface of the bottom plate 100 or
101 and the cover plate 500 or 501 can be used to receive a thinner
article. Accordingly, such application examples should be fall
within the scope of the following claims.
[0045] It can be known from the aforementioned embodiments, the
application of the present invention has the following
advantages:
[0046] 1. all of the parts are formed from s thin sheet of paper
material, and no extra parts have to be fabricated, thus
simplifying the fabrication steps;
[0047] 2. the relative positions of the respective parts of the box
structure can be fixed without using adhesive and pins, thus saving
cost and meeting environmental requirements;
[0048] 3. the buffer space is formed directly from the thin sheet
of paper material, and no extra buffer material is needed;
[0049] 4. the box body itself is used to form a support surface for
disposing articles; and
[0050] 5. the buffer spaces are sufficiently used for disposing
small articles.
[0051] It will be apparent to those skilled in the art that various
modifications and variations can be made to the structure of the
present invention without departing from the scope or spirit of the
invention. In view of the foregoing, it is intended that the
