Description
CROSS-REFERENCES TO RELATED APPLICATIONS
[0001] This non-provisional application is a continuation-in-part
application of U.S. Ser. No. 12/198,748, filed on Aug. 26, 2008,
the entire contents of which are hereby incorporated by
reference.
FIELD OF THE INVENTION
[0002] The present invention relates to a cushioning packing cover
bag, and more particularly to a bendable multi-sectional cushioning
packing cover bag.
BACKGROUND
[0003] Generally, when an article is packed, soft foam or Styron is
provided as a cushioning protection for the article. However, foam
and Styron cause an environmental protection problem; they are not
very ideal cushioning materials considering current attitudes to
environmental protection. In addition, the article will be placed
in a paper box directly after it is packed using foam or Styron, so
as to allow it to be transported conveniently.
[0004] However, a purchaser is unable to see the article directly
after it is placed in the paper box; the contents thereof can only
be judged from an article pattern printed on an outside of the
paper box. This is quite inconvenient, and can cause the purchaser
to be unsatisfied with the article after opening the paper box
owing to misjudgment of the color or size of the article from the
article pattern. Consequently, they will ask for a purchase return
or exchange, embarrassing the merchant considerably. Besides, an
electronic device such as a cellular phone is processed with a
sales promotion with a very low price to attract a purchaser to
buy, owing to severe price competition. But if the purchaser finds
out the cellular phone he bought is secondhand merchandise, or that
the accessories packed inside the box have been replaced with
sub-quality products after he opens the paper box, this not only
always causes a quarrel between the merchant and the purchaser but
also harms the brand image of an electronic device (e.g. cellular
phone) manufacturer.
SUMMARY OF THE INVENTION
[0005] To improve cushioning packing and outer box structure,
strengthen an article's cushioning protection, enable an article to
be seen through an outer box so as to allow a purchaser to view the
color or size of the article directly, ensuring a airtight fit of
the article by means of a cushioning packing structure to prevent
the article from being used or the accessories from being replaced
to avoid a consumption quarrel, and to improve the brand image of a
product manufacturer, the present invention is proposed.
[0006] To achieve the objects mentioned above, the present
invention proposes a bendable multi-sectional cushioning packing
cover bag used for packing an article; it includes:
[0007] two vertically stacked outer films together forming a main
body, the main body including
[0008] a first air cylinder sheet having a plurality of first
cushioning sections and being an air storable space,
[0009] a second air cylinder sheet having a plurality of second
cushioning sections, being an air storable space, and connected to
said first cylinder sheet at a first end thereof, said second sheet
cushioning sections corresponding to said first cushioning
sections, and three sides of each second cushioning section being
adhered to three corresponding sides of said first cushioning
section, and
[0010] an air filling passageway, positioned adjacent to the first
air cylinder sheet or the second air cylinder sheet and being
formed by two sticking lines adhering the two outer films;
[0011] two inner films positioned between the two outer films;
[0012] a plurality of air passageways positioned between the two
inner films and connected to the air filling passageway and at
least one of the first air cylinder sheet or second air cylinder
sheet;
[0013] a heat resistant material, positioned on a face of one sheet
of the inner films facing another sheet of the inner films;
[0014] a plurality of combination points, positioned between the
two sticking lines, each of the combination points lying in between
one sheet of the outer film and one sheet of the inner film to join
said one sheet of the outer film to said one sheet of the inner
film; and
[0015] a light reflection sheet, attached onto one side face of
said first air cylinder sheet facing said second air cylinder sheet
and reflecting light onto an article.
[0016] The present invention also proposes a bendable
multi-sectional cushioning packing cover bag used for packing an
article; it includes:
[0017] a packing box, comprising a window;
[0018] two vertically stacked outer films together forming a main
body, the main body including
[0019] a first air cylinder sheet having a plurality of first
cushioning sections and being an air storable space, a second air
cylinder sheet having a plurality of second cushioning sections,
being an air storable space, and connected to said first cylinder
sheet at a first end thereof, said second cushioning sections
corresponding to said first cushioning sections, three sides of
each second cushioning section being adhered to three corresponding
sides of said first cushioning section, and at least one said
second cushioning section being lodged in said window to allow said
first air cylinder sheet and said second air cylinder sheet to be
placed in said packing box, and
[0020] an air filling passageway, positioned adjacent the first air
cylinder sheet or the second air cylinder sheet and being formed by
two sticking lines adhering the two outer films;
[0021] two inner films, positioned between the two outer films;
[0022] a plurality of air passageways positioned between the two
inner films and connected to the air filling passageway and at
least one of the first air cylinder sheet or second air cylinder
sheet;
[0023] a heat resistant material, positioned on a face of one sheet
of the inner films facing another sheet of the inner films;
[0024] a plurality of combination points, positioned between the
two sticking lines, each of the combination points lying in between
one sheet of the outer film and one sheet of the inner film to join
said one sheet of the outer film to said one sheet of the inner
film; and
[0025] a light reflection sheet, attached onto one side face of
said first air cylinder sheet facing said second air cylinder sheet
and reflecting light onto an article.
[0026] The first cushioning section and the second cushioning
section of the present invention may be made with the same size or
a different size thereby accepting different sizes of articles so
as to accept conveniently a whole set of articles (e.g. cellular
phone and accessories thereof), the first air cylinder and the
second air cylinder sheet are used to guard the article from impact
to prevent the article from being damaged due to shaking during
transportation, and the packaged article is prevented from being
used or replaced to effectively avoid a consumer quarrel and
further to elevate the brand image of a product manufacturer.
Moreover, the second cushioning section may be lodged in a window
of a packing box; this not only allows the first air cylinder sheet
and the second air cylinder to be positioned in the packing box,
but also increases the visual effect of the packing to enable the
original inner packing in the packing box to be a part of the outer
packing, thereby allowing a user to view the packed article
directly and avoid consumer quarrels caused by an error between a
printed pattern of the packing box, and the article itself.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0040] Please refer to FIGS. 1, 2, 3A and 3B. FIG. 1 is a
perspective view, showing a bendable multi-sectional cushioning
packing cover bag of a first embodiment according to the present
invention. FIG. 2 is a schematic view, showing a bendable
multi-sectional cushioning packing cover bag of the first
embodiment according to the present invention when an article is
placed therein. FIG. 3A is a plane view, showing a bendable
multi-sectional cushioning packing cover bag of the first
embodiment according to the present invention. FIG. 3B is a partly
cross sectional view, showing a bendable multi-sectional cushioning
packing cover bag of the first embodiment according to the present
invention.
[0041] The bendable multi-sectional cushioning packing cover bag
includes an air cylinder sheet 1 and a light reflection sheet
31.
[0042] The air cylinder sheet 1 is a sheet includes a plurality of
air cylinders 10a formed by adhering two sheets of outer film 2a
and 2b by means of hot sealing after they are stacked together
vertically, and can be separated into a first air cylinder sheet 11
and a second air cylinder sheet 12 communicating with each other,
in which the first air cylinder sheet 11 is constituted of a
plurality of first cushioning sections 111 disposed in series , and
the second air cylinder sheet 12 is constituted of a plurality of
second cushioning sections 121 disposed in series and one end
thereof is connected to the first air cylinder sheet 11.
[0043] Furthermore, the plurality of second cushioning sections 121
corresponds to the plurality of first cushioning sections 111. The
sizes and dimensions of the plurality of second cushioning sections
121 may be the same or different, and the size and dimension of
each second cushioning section 121 and the size and dimension of
the first cushioning section 111 corresponding thereto are the
same, and three sides thereof are respectively adhered to each
other by means of hot sealing to form a storage space 10b. If the
sizes and the dimensions of the plurality of second cushioning
sections 121 are the same, the dimension of each storage space 10b
is the same; if the sizes and dimensions of the plurality of second
cushioning sections 121 are different, the dimension of each
storage space 10 then matches the size and dimension of the second
cushioning section 121 such that the dimensions of the plurality of
storage spaces 10b are different thereby accepting different
articles 9. The first air cylinder sheet 11 and the second air
cylinder sheet 12 can then be used to guard the articles 9 from
impact as the first air cylinder sheet 11 and the second air
cylinder sheet 12 are filled with air and expanded.
[0044] The light reflection sheet 31 is attached onto one side face
of the first air cylinder sheet 11 close to the second air cylinder
sheet 12 and used for reflecting light onto the article 9, in which
the light reflection sheet 31 may be made from a light reflecting
material.
[0045] The bendable multi-sectional cushioning packing cover bag
may further include an air filling passageway 13 and a continuous
check valve 14, in which the air filling passageway 13 is
positioned at one end of the first air cylinder sheet 11 and formed
by two sticking lines 131 and 132, the continuous check valve 14 is
positioned with a plurality of air inlets 141 and air passageways
142 used for communicating the air filling passageway 13 with the
air cylinder sheet 11, air in the air filling passageway 13 is
filled into each air cylinder 10a via the air inlet 141 and the air
passageway 142 to enable the first cylinder sheet 11 and the second
air cylinder sheet 12 to be filled with air and expanded. Moreover,
the air filling passageway 13 may also be positioned at one end of
the second air cylinder sheet 12; the continuous check valve 14 can
then connect the air filling passageway 13 with the second air
cylinder sheet 12.
[0046] The continuous check valve 14 mentioned above may be formed
by adhering two sheets of inner film 1a and 1b by means of hot
sealing, in which the two sheets of inner film 1a and 1b is
side-attached onto the outer film 2a or 2b. A heat resistant
material 1c is spread sequentially at intervals between the two
sheets of inner film 1a and 1b, for example, by means of heat
resistant resin or ink printing. The two sheets of outer film 2a
and 2b are still not adhered to each other to form air inlets even
by means of hot sealing. When the air filling passageway 13 is
filled with air and expanded, the two sheets of outer film 2a and
2b are pulled apart to open each air inlet 141 to allow air to
enter each air cylinder 10a via each air passageway to cause each
air cylinder 10a to be filled with air and expanded. Furthermore,
two opposite sides of the two sheets of inner film 1a and 1b are
aligned with two corresponding sides of the two sheets of outer
films 2a and 2b as FIG. 3A shows, and the other two opposite sides
of the two sheets of inner film 1a and 1b do not exceed the other
two corresponding sides of the two sheets of outer film 2a and 2b,
as FIG. 3B shows.
[0047] In addition, After the two sheets of outer film 2a, 2b are
stacked together vertically, combination points 2c in an air
filling passageway 13 are generated by means of hot sealing so as
to adhere the outer film 2a to the inner film 1a and the outer film
2b to the inner film 1b. After air entering the air filling
entrance 13a expands the air passageway 13, the two sheets of outer
film 2a and 2b are pulled outward and in the meantime, the two
sheets of inner film 1a and 1b are forced to extend outward through
the combination points 2c so as to open the air inlet 141 to allow
the air to enter the air cylinder 10a via the air passageway
142.
[0048] After the air cylinder 10a is filled with air and expanded,
the internal air pressure of the air cylinder 10a compresses the
two sheets of inner film 1a and 1b to attach onto the outer film 2a
or 2b (the two sheets of inner film 1a and 1b may also be not
side-attached onto the outer film 2a or 2b but may be hung in the
air in the air cylinder 10a) after the air cylinder 10a is filled
with air and expanded to cover air passageway 142 to shield the air
cylinder 10a to prevent the air in the air cylinder 10a leaking out
to achieve an the airtight effect.
[0049] The bendable multi-sectional cushioning packing cover bag
may further include a color sheet 32 attached to a side face of the
first air cylinder sheet 11 not attached to the light reflection
sheet 31, where the color of the color sheet 32 may be changed
depending on the article 9, thereby increasing the visual effect.
In addition, a plurality of hot sealing points 18 may also be
positioned between the two first cushioning sections 111, between
the first cushioning section 111 and the second cushioning section
121, and between the two second cushioning sections 121, to allow
the plurality of first cushioning sections and the plurality of
second cushioning sections to be bent along the plurality of hot
sealing points 18.
[0050] After the article 9 is placed in the storage space 10b, each
second cushioning section 121 and the first cushioning section 111
corresponding thereto are adhered to the opening of the storage
space 10b by means of hot sealing, to cause the storage space 10b
to be shielded, thereby guarding the article 9 from impact.
Furthermore, shielding the storage space 10b by means of hot
sealing can prevent the accepted article 9 from being used or
replaced, effectively avoiding consumer quarrels and further
elevating the brand image of the product manufacturer. In addition,
the articles 9 may be stacked together after being packed according
to the present invention, so as to allow a user to transport or
store them conveniently.
[0051] Please refer to FIGS. 4A and 4B. FIG. 4A is a plane view,
showing a bendable multi-sectional cushioning packing cover bag of
a second embodiment according to the present invention. FIG. 4B is
a cross sectional view, showing a bendable multi-sectional
cushioning packing cover bag of the second embodiment according to
the present invention.
[0052] The continuous check valves 14 may be positioned on the
first cushioning sections 111; air is filled into each air cylinder
10a via the air inlet 141 and the air passageway 142 to cause the
first air cylinder sheet 11 and the second air cylinder 12 to be
filled with air and expanded, and the internal air pressure of the
air cylinder 10a compresses the two sheets of inner film 1a and 1b
against the outer film 2a or 2b (the two sheets of inner film 1a
and 1b may also be left unattached to the outer film 2a or 2b, and
may be hung in the air in the air cylinder 10a), after the air
cylinder 10a is filled with air and expanded to cover air
passageway 142 to shield the air cylinder 10a. Furthermore, the
continuous check valve 14 may also be positioned on the second
cushioning sections 121.
[0053] Please refer to FIGS. 5A and 5B. FIG. 5A is a schematic
view, showing a bendable multi-sectional cushioning packing cover
bag of a third embodiment according to the present invention. FIG.
5B is another schematic view, showing a bendable multi-sectional
cushioning packing cover bag of the third embodiment according to
the present invention.
[0054] The bendable multi-sectional cushioning packing cover bag
may further include a positioning element 15 placed on one end of
one of the first air cylinder sheet 11 and the second air cylinder
sheet 12, in which the positioning element 15 may be a handle as
shown in FIG. 5A, thereby allowing a user to carry the bag more
conveniently, and the positioning element 15 may also be a hole as
shown in FIG. 5B thereby allowing the user to hang the air cylinder
sheet 1 conveniently to store the articles 9 more easily.
[0055] Please refer to FIGS. 6A and 6B. FIG. 6A is a schematic
view, showing a bendable multi-sectional cushioning packing cover
bag of a fourth embodiment according to the present invention. FIG.
6B is another schematic view, showing a bendable multi-sectional
cushioning packing cover bag of the fourth embodiment according to
the present invention.
[0056] The bendable multi-sectional cushioning packing cover bag
may further includes an open close element 16 positioned around the
top rim of the opening of the storage space and used for separating
the storage space 10b from the outside. A user may open or close
the storage space 10b repeatedly with the open close element 16,
rendering it a reusable item, where each storage space 10b may have
a single open close element 16 as FIG. 6A shows, or the plurality
of storage spaces 10b may share the same open close element 16 as
FIG. 6B shows.
[0057] Please FIGS. 7A and 7B. FIG. 7A is a perspective view,
showing a bendable multi-sectional cushioning packing cover bag of
a fifth embodiment according to the present invention. FIG. 7B is
another perspective view, showing a bendable multi-sectional
cushioning packing cover bag of the fifth embodiment according to
the present invention.
[0058] The bendable multi-sectional cushioning packing cover bag
may further include a packing box 5 equipped with a hollow window
51, where the outer surface of the packing box 5 is printed with a
printing pattern of the article 9 or may be printed with a light
reflecting face. Moreover, the shape and size of the window 5 may
be changed depending on the article 9. In addition, a handle 52 may
also be placed on the packing box 5 to allow a user to carry the
packing box 5 more conveniently.
[0059] The second cushioning section 121 may then be lodged in the
window 5 of the packing box 5 after the article 9 is placed in the
storage space 10b so as to allow the first air cylinder sheet 11
and the second air cylinder sheet 12 to be placed in the packing
box 5; this allows a user to view directly the article 9 placed in
the storage space 10b, preventing an error of judgment taking place
because of any difference between the item and the printed pattern
of the packing box 5 avoiding a consumer quarrel. In addition, the
original inner packing in the packing box 5 becomes a part of an
outer packing, and in the meantime the visual effect of the article
packing can be improved to elevate the consumer's purchasing desire
by collocating the printing on the outer surface of the packing box
5 and reflecting light onto the article using the light reflection
sheet 31.
[0060] Although the formation of the continuous check valve 14
mentioned above is described as the two sheets inner film 1a and 1b
adhering to each other by means of hot sealing as an example, it is
not limited to this. It may be that only one sheet of inner film 1b
is placed between the two sheets of outer film 2a and 2b, and a
heat resistant material 1c is spread at intervals between the inner
