Description
CROSS-REFERENCE TO RELATED APPLICATION
[0001] This application claims the priority benefit of China
application serial no. 201821381333.3, filed on Aug. 27, 2018. The
entirety of the above-mentioned patent application is hereby
incorporated by reference herein and made a part of this
specification.
BACKGROUND OF THE INVENTION
Field of the Invention
[0002] The invention relates to a supporting frame and a packing
box, and particularly relates to a supporting frame and a packing
box with the supporting frames stacked for enhanced support and
protection.
Description of Related Art
[0003] Generally, when an object such as an electronic device,
etc., is packaged, a cushion member made of a low density
Expandable Polyethylene (EPE) material is generally disposed on the
top or bottom of the object, and the cushion member and the object
are altogether placed into a paper carton. Support for such a
packing box is mainly provided by the structural strength of the
paper carton itself. Moreover, the cushion member in the paper
carton is mainly used for reducing the impact to the object that
may be caused by a shake or strike.
[0004] However, since the objects may be stacked layer by layer
during transportation or storage, the paper cartons located at
lower layers need to support weights of the objects on upper
layers. During an air transportation, the cushion member is easily
contracted due to an air pressure, such that the paper cartons
located at the lower layers cannot support the weights of the
objects on the upper layer, resulting in paper carton deformation.
Moreover, the paper carton itself may also be dampened due to
weather factors, resulting in insufficient support and deformation.
In addition, the cushion member with a certain thickness may
increase a height of the paper carton, such that the number of
layers of the paper cartons that may be placed in a container is
limited.
[0005] The information disclosed in this BACKGROUND section is only
for enhancement of understanding of the BACKGROUND section of the
described technology and therefore it may contain information that
does not form the prior art that is already known to a person of
ordinary skill in the art. Further, the information disclosed in
the BACKGROUND section does not mean that one or more problems to
be resolved by one or more embodiments of the disclosure were
acknowledged by a person of ordinary skill in the art.
SUMMARY OF THE INVENTION
[0006] The invention is directed to a supporting frame, to provide
enhanced support and cushioning effect for an object.
[0007] The invention is directed to a packing box, which adopts the
above supporting frame to achieve an enhanced support effect and a
smaller height.
[0008] Other objects and advantages of the invention may be further
illustrated by the technical features broadly embodied and
described as follows.
[0009] In order to achieve one or a part or all the objectives or
other objectives, an embodiment of the invention provides a
supporting frame, which is disposed in a packing box used for
packing an object. The supporting frame includes a substrate and a
cushion assembly. The substrate includes a bottom plate, where the
bottom plate has a first surface and a second surface opposite to
each other. The cushion assembly includes a first portion and a
second portion, the first portion is fixed at four corners of the
first surface of the bottom plate, and the second portion is fixed
at four corners of the second surface of the bottom plate, where at
least an inner contour of the first portion of the cushion assembly
partially corresponds to an outer contour of the object.
[0010] In order to achieve one or a portion of or all of the
objects or other objects, an embodiment of the invention provides a
packing box adapted to pack an object. The packing box includes an
outer box, a first supporting frame and a second supporting frame.
The first supporting frame is disposed in the outer box, the first
supporting frame and the second supporting frame are disposed in
the outer box in a stack manner, and the object is disposed between
the first supporting frame and the second supporting frame, and any
one of the first supporting frame and the second supporting frame
includes a substrate and a cushion assembly. The substrate includes
a bottom plate, where the bottom plate has a first surface and a
second surface opposite to each other. The cushion assembly
includes a first portion and a second portion, the first portion is
fixed at four corners of the first surface of the bottom plate, and
the second portion is fixed at four corners of the second surface
of the bottom plate, where at least an inner contour of the first
portion of the cushion assembly partially corresponds to an outer
contour of the object.
[0011] Based on the above description, instead of a supporting
structure comprised of merely cushiony material, the supporting
frame of the invention uses the combination of the substrate and
the cushion assembly. Conventionally, the supporting structure
comprised of merely cushiony material is required to have a
significantly thickness so as to achieve an effective support. In
the supporting frame of the invention, the thinner substrate itself
provides a good structural strength and thus an effective support.
Moreover, a first portion of the cushion assembly is disposed at
four corners of the first surface of the bottom plate of the
substrate, and at least the inner contour of the first portion of
the cushion assembly partially corresponds to the outer contour of
the object, so as to fix and protect the object. The second portion
of the cushion assembly is fixed at the four corners of the second
surface of the bottom plate, so that an impact or a shock may be
preferably absorbed effectively. The packing box of the invention
has the aforementioned supporting frame, so that a thinner packing
box may provide an effective support and cushioning. Therefore, in
a limited storage space, the packing boxes of the invention may be
stacked in more layers, so as to increase the amount of boxes to be
delivered and decrease the cost thereof.
[0012] Other objectives, features and advantages of the present
invention will be further understood from the further technological
features disclosed by the embodiments of the present invention
wherein there are shown and described preferred embodiments of this
invention, simply by way of illustration of modes best suited to
carry out the invention.

of describing directions in the figures only. Accordingly, the
drawings and descriptions will be regarded as illustrative in
nature and not as restrictive.
[0022] Generally, objects are stacked into layers during a delivery
or storage process, and packing boxes located at lower layers need
to support weights of the objects on upper layers. Therefore, the
affordability of the packing box at a lower layer for the weight
placed thereon is required to satisfy the following equation: the
affordability of the packing box at a lower layer for the weight
placed thereon (box pressure).gtoreq.a safety coefficient.times.a
package weight.times.(the number of stacked layers-1), where the
number of the stacked layers.gtoreq.2. The safety coefficient is
influenced by factors such as a storage time, a stacking manner, a
delivery manner, etc. The safety coefficient may be generally about
4 to 8 in use.
[0023] For example, if the package weight of the object is 50 kg,
the safety coefficient is 8, the number of stacked layers is 5, it
may be calculated that the weight required to be withstood by the
packing box at the lowermost layer is 1600 kg, which means that the
packing box at the lowermost layer should be able to withstand a
weight of at least 1600 kg. However, it is difficult to meet the
above requirements by the paper-made outer box.
[0024] The supporting frame of the embodiment may be disposed in an
outer box to enhance an overall structural strength of the packing
box, so as to provide an effective support to satisfy a weight
bearing demand. Moreover, the supporting frame of the embodiment
may be used for wrapping the object to provide good protection and
cushioning for the object. A supporting frame 100 is described
below.
[0025] FIG. 1 is a three-dimensional view from a front side of a
supporting frame according to an embodiment of the invention. FIG.
2 is a three-dimensional view of a back side from the supporting
frame of FIG. 1. Referring to FIG. 1 and FIG. 2, in the embodiment,
the supporting frame 100 includes a substrate 110 and a cushion
assembly 140 disposed on the substrate 110. In the embodiment, a
material of the substrate 110 is, for example, corrugated paper
which may provide effective support and may have effectively
increased strength to support the pressure, such that the overall
weight affordability of the packing box 10 may be increased, and
the thickness of the supporting frame 100 may be decreased. A
material of the cushion assembly 140 is, for example, a low density
Expandable Polyethylene (EPE) material which may provide preferable
cushioning due to the ability of shape recovery after being
compressed. Certainly, the materials of the substrate 110 and the
cushion assembly 140 are not limited thereto. In other embodiments,
the substrate 110 may also be a plastic member, and the cushion
assembly 140 may be rubber, silica gel, a foam material or a
spring.
[0026] In the embodiment, the substrate 110 includes a bottom plate
120. The bottom plate 120 has a first surface 121 and a second
surface 122 opposite to each other. The cushion assembly 140
includes a first portion 142 and a second portion 146. As shown in
FIG. 1, the first portion 142 of the cushion assembly 140 is at
least fixed at four corners of the first surface 121 of the bottom
plate 120. In the embodiment, an object (not shown, which is, for
example, an electronic device such as a projector, etc., though the
invention is not limited thereto) is placed on the first surface
121 of the bottom plate 120, and at least a part of the first
portion 142 of the cushion assembly 140 surrounds the object to
provide protection.
[0027] To be more specific, as shown in FIG. 1, in the embodiment,
a main accommodation space S1 is formed and surrounded by a part of
the first portion 142 of the cushion assembly 140, and the object
may be placed in the main accommodation space S1. At least an inner
contour of the first portion 142 of the cushion assembly 140 (such
as the part surrounding the main accommodation space S1) may
partially correspond to an outer contour of the object, so as to
fix the object. Moreover, as shown in FIG. 2, in the embodiment,
the second portion 146 of the cushion assembly 140 is at least
fixed at four corners of the second surface 122 of the bottom plate
120, so that an impact or a shock may be preferably absorbed
effectively.
[0028] Instead of a supporting structure comprised of merely
cushiony material, the supporting frame 100 of the embodiment uses
the combination the substrate 110 and the cushion assembly 140.
Since the substrate 110 itself may provide a good structural
strength, good support may be provided under the premise of a
smaller thickness.
[0029] Moreover, as shown in FIG. 1, the substrate 110 further
includes a plurality of sidewalls 130 surrounding a periphery of
the bottom plate 120, and the sidewalls 130 surround the first
portion 142 of the cushion assembly 140. In the embodiment, the
substrate 110 has four sidewalls 130 connected in pairs, and the
four sidewalls 130 respectively extend from four edges of the
bottom plate 120 toward a direction protruding out of the first
surface 121. In the embodiment, the four sidewalls 130 and the
bottom plate 120 commonly construct, for example, a short box
structure. The sidewalls 130 are connected to each other and
connected to the bottom plate 120, so as to effectively increase an
overall structural strength of the substrate 110. In the
embodiment, the bottom plate 120 and the sidewalls 130 are, for
example, formed integrally. Certainly, the relationship between the
bottom plate 120 and the sidewalls 130 of the substrate 110 is not
limited thereto.
[0030] Moreover, according to FIG. 1, in the embodiment, the
sidewalls 130 are equal to the first portion 142 of the cushion
assembly 140 in height. In the above configuration, the sidewalls
130 of the supporting frame 100 and the first portion 142 of the
cushion assembly 140 may together provide the support. Certainly,
in other embodiments, the first portion 142 of the cushion assembly
140 may also be slightly lower than the sidewalls 130, which is not
limited to the invention.
[0031] As shown in FIG. 2, in the embodiment, the second portion
146 of the cushion assembly 140 further includes a portion fixed to
a central region of the second surface 122 of the bottom plate 120.
Since the second portion 146 located at the central region of the
second surface 122 is overlapped with the object, it may provide
better cushioning for the object and the object may also be well
fixed.
[0032] Moreover, since the packed object is, for example, a
projector, and the projector has supporting legs for being used on
a table. In the embodiment, as shown in FIG. 1, the bottom plate
120 has first through holes 125, and positions of the first through
holes 125 correspond to positions of the supporting legs of the
object, such that the supporting legs may pass through and an
overall height of the package may be decreased. According to FIG.
2, the second portion 146 of the cushion assembly 140 has second
through holes 148, and positions of the second through holes 128
correspond to the first through holes 125 of the bottom plate 120,
such that the supporting legs of the object may pass through.
[0033] FIG. 3 is an appearance schematic view of a packing box
according to an embodiment of the invention. Referring to FIG. 3,
the packing box 10 of the embodiment is used for packing an object
(not shown), and used for providing protection for the object, such
that the delivery of the object may be easier. For example, the
object is an electronic device such as a projector, though the type
of the object is not limited thereto. In the embodiment, the
packing box 10 includes an outer box 20 and two supporting frames
100 (shown in FIG. 6 and FIG. 7) disposed in the outer box 20. The
components configured in the outer box 20 are described in detail
below.
[0034] FIG. 4 is a schematic view of a surrounding multi-plate
reinforcement of the packing box of FIG. 3. FIG. 5 is a schematic
view of the surrounding multi-plate reinforcement of the packing
box of FIG. 3 in the outer box. Referring to FIG. 4 and FIG. 5, in
the embodiment, the packing box 10 may optionally include a
surrounding multi-plate reinforcement 30, which is configured in
the outer box 20 and corresponds to sidewalls 23 of the outer box
20. In the embodiment, a material of the surrounding multi-plate
reinforcement 30 is, for example, a corrugated paper, though the
material of the surrounding multi-plate reinforcement 30 is not
limited thereto. Moreover, in the embodiment, a height of the
surrounding multi-plate reinforcement 30 is close to a height of
the sidewalls 23 of the packing box 10. The surrounding multi-plate
reinforcement 30 is configured to increase a structural strength of
the packing box 10, so that the weight affordability of the packing
box 10 may be increased. Moreover, in the embodiment, the
surrounding multi-plate reinforcement 30 includes a plurality of
handle holes 34, and positions of the handle holes 34 correspond to
positions of handle holes (not shown) on the outer box 20, which
are disposed for the convenience of a user to lift the
structure.
[0035] FIG. 6 is a schematic view of the supporting frame of FIG. 1
placed in the outer box of FIG. 5. FIG. 7 is a schematic view of
another supporting frame placed in the outer box of FIG. 6.
Referring to FIG. 6 and FIG. 7, in the embodiment, the supporting
frame 100 in FIG. 6 and the supporting frame 100 in FIG. 7 are both
illustrated as examples of the supporting frames 100 shown in FIG.
1 and FIG. 2. Namely, in the embodiment, the two supporting frames
100 are identical. To be more specific, the shape of the substrate
110 of the supporting frame 100 located at a lower position is the
same as the shape of the substrate 110 of the supporting frame 100
located at an upper position, and the configuration position of the
cushion assembly 140 of the supporting frame 100 located at the
lower position on the substrate 110 is the same as the
configuration position of the cushion assembly 140 of the
supporting frame 100 located at the upper position on the substrate
110. In such configuration, simple manufacture and
mistake-prevention (error-prevention) during assembling may be
advantageously achieved.
[0036] Certainly, in other embodiments, the supporting frame
located at the lower position may be different from the supporting
frame located at the upper position. Namely, shapes of the
substrates 110 of the two supporting frames 100, or/and
configuration positions of the two cushion assemblies 140 on the
two substrates 110 may be different. As long as each of the
supporting frames 100 includes a substrate 110 and a cushion
assembly 140, the first portion 142 of the cushion assembly 140 is
at least fixed at the four corners of the first surface 121 of the
bottom plate 120, and the second portion 146 of the cushion
assembly is at least fixed at the four corners of the second
surface 122 of the bottom plate 120, it is considered to be within
the scope of the invention.
[0037] In the embodiment, two supporting frames 100 are stacked in
the outer box 20, and an object is disposed between the two
supporting frames 100. To be specific, in the embodiment, when a
worker assembles the packing box 10, the worker may first places
one supporting frame 100 in the outer box 20 as that shown in FIG.
6. The second surface 122 of the supporting frame 100 faces a
bottom wall 21 of the outer box 20. Namely, the first surface 21 of
the supporting frame 100 faces upward. Then, the object is placed
in the main accommodation space S1 of the supporting frame 100.
Thereafter, as shown in FIG. 7, another supporting frame 100 is
placed on the object. As for the supporting frame 100 located at
the upper position, the first surface 121 thereof faces the object,
and the second surface 122 thereof faces upward.
[0038] Therefore, in the embodiment, when the object is disposed
between the two supporting frames 100, two first surfaces 121 of
two supporting frames 100 both face the object. The object is
located in the two main accommodation spaces S1 of the two
supporting frames 100. Moreover, when the two supporting frames 100
are stacked to each other, the supporting frame 100 located at the
lower position may support, using the four sidewalls 130 thereof,
the four sidewalls 130 of the supporting frame 100 located at the
upper position, so that the two supporting frames 100 are firmly
stacked in an up and down manner. According to FIG. 7, sidewalls 23
and the surrounding multi-plate reinforcement 30 all surround the
two supporting frames 100, to provide a lateral support for the two
supporting frames 100.
[0039] It should be noted that, in order to make the packing box 10
to have a margin to add accessories at any time, referring to FIG.
3, in the embodiment, the outer box 20 has a U-shaped slit 22
located on the sidewall 23, and a portion of the sidewall 23
surrounded by the U-shaped slit 22 is adapted to be folded to form
a first opening 24. With reference of FIG. 4, in the embodiment,
the surrounding multi-plate reinforcement 30 has a second opening
32 corresponding to the first opening 24. Referring back to FIG. 1,
in the embodiment, the cushion assembly 140 of the supporting frame
100 further includes an extension section 144 of the first portion
142, which extends from one of the first portions 142 located the
four corners. According to FIG. 1, the extension section 144 of the
first portion 142 extends from a right corner of FIG. 1 toward a
central position, and an accommodation space S3 for an accessory is
defined between the extension section 144 and the corresponding
sidewall 130. Moreover, in the supporting frame 100 of the
embodiment, the sidewall 130 corresponding to the extension section
144 has a first notch 132, and the first notch 132 is recessed
downward from a part of the sidewall 130 located away from the
bottom plate 120, so that a height of the first notch 132 is lower
than a height of the extension section 144. When the two supporting
frames 100 are stacked in the outer box 20, where one of the
supporting frames 100 is placed facing up and another facing down,
two first notches 132 of the two supporting frames 100 may be
combined to form one big opening.
[0040] Therefore, in the packing box 10 of the embodiment, in an
inward direction, the first opening 24 (shown in FIG. 3) of the
sidewall 23 of the outer box 20 sequentially corresponds to the
second opening 32 (shown in FIG. 4) of the surrounding multi-plate
reinforcement 30, the big opening formed by combining the two first
notches 132 (shown in FIG. 1) of the two supporting frames 100 and
the two accommodation spaces S3 for accessories of the two
supporting frames 100. After a cover of the outer box 20 is closed,
through the first opening 24 on the sidewall 23 of the outer box
20, the above connected and corresponding openings and spaces allow
the user to place additional accessories into the accommodation
space S3 for accessories of the supporting frame 100. Therefore,
convenience for adding accessories at any time may be provided.
[0041] For example, different power cord plugs may be used in
different countries. In a standard configuration, a commonly used
power cord plug is probably provided, and in the packing box 10, a
most commonly used power cord plug may be probably placed in an
accessory box 12 shown in FIG. 7. However, in case that the packing
box 10 is delivered to a different country where a different type
of power cord plug is required, a local supplier may add a required
power cord plug into the accommodation space S3 for an accessory of
the packing box 10 without opening the packing box 10. Certainly,
power cord plugs are only examples, and the type of the accessory
is not limited to the power cord plugs.
[0042] Moreover, as shown in FIG. 1, in the embodiment, the bottom
plate 120 has a second notch 123 recessed inward from a side, the
bottom plate 120 is hollow at the second notch 123 without
connecting to a corresponding sidewall 130. Referring to FIG. 1 and
FIG. 7, in the embodiment, the second notch 123 may serve as an
accommodation space S2 for an accessory to accommodate the
accessory box 12. In the embodiment, since the second notch 123 is
a hollow portion of the bottom plate 120, in the packing box 10,
positions of the two second notches 123 of the two supporting
frames 100 correspond to each other, so as to provide a space for
accommodating the accessory box 12 with a height close to a height
of the outer box. Certainly, the type of the second notch 123 is
not limited thereto. In the embodiment, the position of the
accessory box 120 and the position of the object are in a same
plane, and such configuration may reduce the height of the packing
box 10, so that more layers of the packing boxes 10 may be stacked
under a limited container volume. Moreover, in the embodiment, the
bottom plate 120 of the supporting frame 100 has a through handle
124 at a part away from the second notch 123, so as to allow the
user to take the supporting frame 100 easily. Therefore, the
assembling and disassembling of the supporting frame 100 is
easy.
[0043] In summary, instead of a supporting structure comprised of
merely cushiony material, the supporting frame of the invention
uses the combination of the substrate and the cushion assembly.
Conventionally, the supporting structure comprised of merely
cushiony material is required to have a significantly thickness so
as to achieve an effective support. In the supporting frame of the
invention, the thinner substrate itself provides a good structural
strength and thus an effective support. Moreover, a first portion
of the cushion assembly is disposed at four corners of the first
surface of the bottom plate of the substrate, and at least the
inner contour of the first portion of the cushion assembly
partially corresponds to the outer contour of the object, so as to
fix and protect the object. The second portion of the cushion
assembly is fixed at the four corners of the second surface of the
bottom plate, so that an impact or a shock may be preferably
absorbed effectively. The packing box of the invention has the
aforementioned supporting frame, so that a thinner packing box may
provide an effective support and cushioning. Therefore, in a
limited storage space, the packing boxes of the invention may be
stacked in more layers, so as to increase the amount of boxes to be
delivered and decrease the cost thereof.
