Description
TECHNICAL FIELD
[0001] The present invention relates to a packaging case. More
particularly, the present invention relates to a packaging case, in
which an inner case for packaging a product is fixed inside an
outer case to accommodate and package the product.
BACKGROUND ART
[0002] Generally, in order to prevent a product from being
scratched or damaged, the product is packaged by a packaging
case.
[0003] However, a conventional packaging case has an integrated
structure, so that the packaging case is likely to be damaged by an
action of throwing the packaging case during transport or by an
external force.
[0004] Particularly in post offices or parcel delivery service
companies transporting and handling various kinds of packaging
cases, in some cases, the packaging case may be frequently thrown
so as to reduce a transport time when the packaging case is loaded
into a loading box, thus leading to a damage to the packaging case
and consequently causing the packaged product to be frequently
exposed or damaged.
[0005] Therefore, there is an urgent need for development of a
packaging case that is not easily damaged by an external force
during transport.

BEST MODE FOR THE INVENTION
[0017] Exemplary embodiments of the present invention will be
described below in more detail with reference to the accompanying
drawings.
[0018] FIGS. 1 to 3 illustrate a packaging case according to an
embodiment of the present invention. As illustrated in the
drawings, the packaging case 1 according to the embodiment of the
present invention includes an inner case 10 and an outer case
30.
[0019] The inner case 10 serves to package a product. In this
embodiment, the inner case 10 has the shape of a square pillar that
is open at both sides thereof.
[0020] As illustrated in FIG. 2, four inner folding lines 21 are
formed on a surface of the inner case 10 to form four inner
sidewalls 11, 13, 15 and 17. The four inner folding lines 21 are
formed at intervals in a longitudinal direction of the inner case
10.
[0021] Among the four inner sidewalls 11, 13, 15 and 17, one inner
sidewall 11 includes a first overlapping portion 11a and a second
overlapping portion 11b that are cut to partially overlap each
other.
[0022] Meanwhile, a pair of cut-out portions 25, which is partially
cut into the shape of a triangular cross-section to be foldable, is
formed at intervals on a surface of the first overlapping portion
11a. A free end of the second overlapping portion 11b is fitted
into each cut-out portion 25, so that the first overlapping portion
11a and the second overlapping portion 11b constitute the same
inner sidewall 11.
[0023] Although the cut-out portion 25 is shown in this embodiment
as being partially cut into the triangular cross-sectional shape,
the cut-out portion 25 may be partially cut into any one of
circular, elliptical and polygonal cross-sectional shapes without
being limited to the triangular cross-sectional shape.
[0024] Moreover, the first overlapping portion 11a and the second
overlapping portion 11b are shown in this embodiment as being
coupled to each other in a fitting method using the cut-out
portions 25. However, the first overlapping portion 11a and the
second overlapping portion 11b may be attached to each other by an
adhesive or tape without being limited to fitting.
[0025] Although not shown in the drawings, in the inner case 10 of
the packaging case 1 according to the present invention, facing
edges of the first overlapping portion 11a and the second
overlapping portion 11b may be attached to each other by the
adhesive such as hot melt, or the first overlapping portion 11a and
the second overlapping portion 11b may be attached to each other by
the tape, instead of overlapping the first overlapping portion 11a
and the second overlapping portion 11b.
[0026] The outer case 30 serves to accommodate and package the
inner case 10. In this embodiment, the outer case 30 has the shape
of a square pillar that is open at both sides thereof. The outer
case 30 includes support pieces 41 that support the pair of facing
inner sidewalls 13 and 17 of the inner case 10 to prevent an
undesired movement of the inner case 10.
[0027] As illustrated in FIG. 3, four transverse folding lines 45
for forming four outer sidewalls 31, 33, 35 and 37 and two
longitudinal folding lines 47 for forming the support pieces 41 are
formed on the surface of the outer case 30. The four transverse
folding lines 45 are formed at intervals in a longitudinal
direction of the outer case 30, and the two longitudinal folding
lines 47 are formed at intervals to be perpendicular to the
transverse folding lines 45.
[0028] Meanwhile, the four transverse folding lines 45 are formed
to be spaced apart from each other in a size corresponding to
transverse and longitudinal sides of the pair of inner sidewalls 13
and 17 supported by the support pieces 41 of the inner case 10.
[0029] The two longitudinal folding lines 47 are formed,
respectively, inside both longitudinal sides of the surface of the
outer case 30 in a size corresponding to a depth to which the inner
case 10 is accommodated from an end of the outer case 30. By
folding the surface of the outer case 30 along the longitudinal
folding lines 47, the support pieces 41 are formed, which support
the pair of facing inner sidewalls 13 and 17 of the inner case 10
to prevent an undesired movement of the inner case 10.
[0030] Among the four outer sidewalls 31, 33, 35 and 37, one outer
sidewall 31 is cut into two equal parts, a first panel 31a and a
second panel 31b. The first panel 31a and the second panel 31b may
be attached at facing edges thereof to each other by the adhesive
such as the hot melt, or may be attached to the inner case 10 by
the adhesive such as the hot melt, or may be attached to each other
by the tape.
[0031] Thus, the packaging case 1 according to the present
invention is configured such that the inner case 10 is disposed
between the pair of longitudinal folding lines 47. The outer case
30 surrounds the pair of inner sidewalls 11 and 15 of the inner
case 10 that are not supported by the support pieces 41 and both
openings of the inner case 10, and accommodates the inner case
10.
[0032] A process of packaging a product using the packaging case 1
according to the present invention configured as described above
will be described below.
[0033] First, as illustrated in FIGS. 2 and 3, a spread cardboard
for the inner case 10 corresponding to the size of the product to
be packaged and a spread cardboard for the outer case 30
corresponding to the size of the inner case 10 are prepared.
[0034] Next, the product to be packaged is put on the spread
cardboard for the inner case 10, and the inner case 10 is folded
along each inner folding line 21, and the free end of the second
overlapping portion 11b is fitted into the cut-out portion 25 of
the first overlapping portion 11a, so that the packaging of the
inner case 10 is completed.
[0035] Further, as illustrated in FIG. 4, the outer case 30 is
folded inwards along the longitudinal folding line 47, so that the
support piece 41 is formed on the outer case 30.
[0036] Subsequently, as illustrated in FIG. 5, the inner case 10 is
positioned on the surface of the outer case 30 so that the pair of
facing inner sidewalls 13 and 17 of the inner case 10 comes into
close contact with the pair of support pieces 41.
[0037] As illustrated in FIGS. 6 and 7, sequentially, the outer
case 30 is folded along each transverse folding line 45, so that
the inner case 10 is accommodated in the outer case 30 to surround
the pair of inner sidewalls 11 and 15 of the inner case 10 that are
not supported by the support pieces 41 and both openings of the
inner case 10.
[0038] In this regard, the inner case 10 is accommodated to a depth
corresponding to a width of the support piece 41 of the outer case
30 from an end of the outer case 30.
[0039] Subsequently, when the first panel 31a and the second panel
31b are attached to each other by the adhesive such as the hot
melt, as illustrated in FIG. 1, the pair of sidewalls of the inner
case 10 exposed through the openings of the outer case 30 is firmly
fixed by the support pieces 41 of the outer case 30. Thus, the
packaging case 1 according to the present invention is
completed.
[0040] As such, according to the present invention, the packaging
case adopts a dual structure having the inner case and the outer
case, and firmly supports the inner case using the outer case, thus
absorbing shocks exerted on the product that is accommodated and
packaged in the inner case, allowing the inner case to be reliably
fixed, and preventing the packaged product from being exposed and
damaged.
[0041] Although the support pieces of the outer case are shown in
the above-described embodiment as being supported along four sides
of the sidewalls of the inner case, the support pieces may be
supported along at least one side of the sidewalls of the inner
case without being limited thereto. Further, in the above-described
embodiment, the inner case has four inner sidewalls. However, the
inner case may have three or five or more inner sidewalls without
being limited thereto.
[0042] Furthermore, the inner case is prepared in a size
corresponding to the size of the product to be packaged and then is
used to package the product, thus preventing the packaged product
from being shaken during the transport of the packaging case, and
reducing a damage to a package. At this time, the pair of inner
sidewalls of the inner case supported by the support pieces may
come into close contact with the product to be packaged to support
the product.
