VIBRATION-ABSORBING AIR SHEATH HAVING IMPROVED END-CLOSING
STRUCTURE
Abstract
A vibration-absorbing air sheath having improved end-closing
structure includes a first and a second buffering walls, at least
one first and at least one second nodes, a third buffering wall and
an accommodating space. The buffering walls are constructed by air
columns. The first and second buffering walls are atop heat-sealed
together at each of two ends of the air sheath so as to form a
binding portion and a lower flat-bottomed opening. After inflation
of the air columns, the air columns of the first and second
buffering walls outside the binding portion and the air columns of
the third buffering wall form a triangular end buffering portion.
The air columns in the end buffering portion have slanted creases
for their easy upward-bending so as to make the air columns in the
end buffering portion spread and provide a maximized buffering area
at the end of the air sheath's ends.

Description
BACKGROUND OF THE INVENTION
[0001] 1. Technical Field
[0002] The present invention relates to packing materials, and more
particularly, to a vibration-absorbing air sheath that has air
columns processed by heat sealing so that the air columns are
shaped through interaction therebetween caused by air pressure and
thereby has improved end-closing structure.
[0003] 2. Description of Related Art
[0004] There has been a vacuum-based, hammock-type
vibration-absorbing sheath mainly comprises: a first buffering
wall, composed of a plurality of air columns that are formed by a
plurality of heat-seal edges, and having one side formed with an
extended edge; a second buffering wall, composed of a plurality of
air columns that are formed by a plurality of heat-seal edges; a
third buffering wall, composed of a plurality of air columns that
are formed by a plurality of heat-seal edges, and having one side
formed with an extended edge; an accommodating space, defined by
the first, second and third buffering walls; an internal membrane,
having a bag-like structure made of flexible PE film, PE composite
film or plastic sheet, and being connected to the extended edges of
the first and third buffering walls through an opening edge, so
that the internal membrane is suspended in the accommodating space.
In use of the prior-art device, the object to be packed is first
placed into the internal membrane, and an external apparatus is
used to suck out air in the internal membrane, so as to make the
interior of the internal membrane a vacuum environment and make the
internal membrane completely wrap the object. At last, the extended
edges of the first and third buffering walls and the open edge of
the internal membrane are heat-sealed together with the interior of
the internal membrane remaining vacuum. Thereby, the object during
transport is wrapped by the internal membrane and embraced by the
first, second and third buffering walls, and obtains effective
buffering protection.
[0005] The aforementioned structure mainly features attaching an
open edge of the internal membrane to the extended edges of the
first buffering wall and the third buffering wall, so that the
internal membrane is positioned in the accommodating space formed
by the first, second and third buffering walls. After an object to
be packaged is placed into the internal membrane, an external
apparatus is made to suck air from the internal membrane until the
interior of the internal membrane becomes a vacuum while the
internal membrane completely wraps the object to be packaged. With
the buffering protection provided by the first, second and third
buffering walls, the objective is well protected. Despite the
foregoing features, the prior art is defective as the joints
between the buffering walls tend to be formed as irregular,
towering corners, which when receiving squeezes or impacts are
likely to have their air columns bursting, and in turn make the
entire buffering structure lose the vibration-absorbing
function.
SUMMARY OF THE INVENTION
[0006] The present invention provides a vibration-absorbing air
sheath having improved end-closing structure. The
vibration-absorbing air sheath is for wrapping an object and
providing buffering protection to the object, and primarily
comprises a first buffering wall, a second buffering wall, at least
one first node, at least one second node, a third buffering wall
and an accommodating space. Therein, the first buffering wall
includes at least one first heat-seal edge and a plurality of air
columns separated therebetween by air column lines that are made
through heat sealing and are perpendicular to the first heat-seal
edge. The second buffering wall includes at least one second
heat-seal edge that is heat-sealed to the first heat-seal edge, and
includes a plurality of air columns separated therebetween by air
column lines that are made through heat sealing and are
perpendicular to the second heat-seal edge. The first node located
on the first buffering wall so that the first buffering wall is
allowed to be bent against the first node. The second node located
on the second buffering wall so that the second buffering wall is
allowed to be bent against the second node. The third buffering
wall is formed by bending the first buffering wall and the second
buffering wall so as to be defined and connected between the first
buffering wall and the second buffering wall. The accommodating
space is formed by bending the first buffering wall and the second
buffering wall so as to be defined between the first buffering wall
and the second buffering wall. The vibration-absorbing air sheath
is characterized in that at each of two opposite ends of the
vibration-absorbing air sheath, the first buffering wall and the
second buffering wall have said air column lines thereof that come
to contact with each other after the bending bound through heat
sealing, such that at each said end of the vibration-absorbing air
sheath, an opening is formed between lower parts of the first and
second buffering walls while a binding portion is formed between
upper parts of the first and second buffering walls, in which the
opening has a flat bottom, whereby after inflation of the air
columns, the air columns of the first and second buffering walls
outside the binding portion and the air columns of the third
buffering wall jointly form a triangular end buffering portion of
the vibration-absorbing sheath.
[0007] A secondary objective of the present invention is that by
providing at least one of the air columns of the first and second
buffering walls in the end buffering portion in the lower part
thereof with at least one slanted crease, the air column is allowed
to have a part below the crease bent upward against the crease,
thereby closing the end of the vibration-absorbing air sheath and
making the air columns in the end buffering portion with parts
thereof above the crease spread out and form a flat plane, so as to
provide a maximized buffering area for the end buffering
portion.
[0008] Another objective of the present invention is that by making
the air columns of each of the first and second buffering walls
inside the binding portion include one first air column and one
second air column that are adjacent to each other and have
different diameters, a width of the accommodating space
corresponding to the binding portion is maximized as the first air
column and the second air column jostle with each other.
[0009] Still another objective of the present invention is that,
that by making each of the air column lines between the air columns
inside the binding portion have an inclined upper end, an edge of
an opening of the accommodating space open corresponding to the
binding portion is prevented from becoming wavy.

DETAILED DESCRIPTION OF THE INVENTION
[0029] For achieving the foregoing objectives and features, one
preferred embodiment is herein described with reference the
accompanying drawings for people having ordinary skill in the art
to better implement the present invention.
[0030] Referring to FIG. 1 through FIG. 4, FIG. 9, FIG. 10 and FIG.
17 for a perspective view of one preferred embodiment of the
present invention, a cross-sectional view of an accommodating space
the preferred embodiment of the present invention, a
cross-sectional view of a binding portion of the preferred
embodiment of the present invention, a cross-sectional view of
adjacent air columns inside the binding portion the preferred
embodiment of the present invention, an exploded view of the
preferred embodiment of the present invention, an expanded view of
the first, second and third buffering walls according to the
preferred embodiment of the present invention and an applied view
of the preferred embodiment of the present invention. As shown, the
disclosed vibration-absorbing air sheath 100 is for wrapping an
object 200 and providing buffering protection to the object 200,
and mainly comprises a first buffering wall 1, a second buffering
wall 2, at least one first node 3, at least one second node 4, a
third buffering wall 5 and an accommodating space 6. The first
buffering wall 1 has a first heat-seal edge 10 that is formed
through heat sealing as the upper edge of the first buffering wall
1. The first buffering wall 1 is composed of a plurality of air
columns 11 that are perpendicular to the first heat-seal edge 10.
Each two air columns 11 are separated by an air column line 111
that is also formed through heat sealing. In this way, the air
columns 11 are arranged abreast to form the first buffering wall 1.
The second buffering wall 2 is structurally similar to the first
buffering wall 1 and corresponds to the first buffering wall 1. The
second buffering wall 2 is connected to the first heat-seal edge 10
through heat sealing, and has at least one second heat-seal edge
20. The second heat-seal edge 20 is also formed through heat
sealing as the upper edge of the second buffering wall 2.
Similarly, the second buffering wall 2 is composed of a plurality
of air columns 21 perpendicular to the second heat-seal edge 20.
The air columns 21 are also separated by air column lines 211 made
through heat sealing, and arranged abreast to form the second
buffering wall 2.
[0031] Basing on the configuration stated above, in the air columns
11 and 21 of the first buffering wall 1 and the second buffering
wall 2, at their sides opposite to the first heat-seal edge 10 and
the second heat-seal edge 20, first nodes 3 and second nodes 4 are
provided, respectively. The nodes 3, 4 are such formed that they do
not break the communication between the corresponding air columns
11 and 21 and allow the first buffering wall 1 and the second
buffering wall 2 to be bent against the first node 3 and the second
node 4, respectively. Thus, by bending the first buffering wall 1
and the second buffering wall 2, the third buffering wall 5 is
defined and connected between the first buffering wall 1 and the
second buffering wall 2. Then the connection among the first
buffering wall 1, the second buffering wall 2 and the third
buffering wall 5 further defines the accommodating space 6. In
addition, the third buffering wall 5 is structurally similar to the
second buffering wall 2 and the first buffering wall 1. It also has
a plurality of air columns 51 perpendicular to the first heat-seal
edge 10 and the second heat-seal edge 20 and separated by air
column lines 510 made through heat sealing. The air column 51 of
the third buffering wall 5 may correspond to the air columns 11, 12
of the first buffering wall 1 and the second buffering wall 2 in a
one-to-one or one-to-many manner. The corresponding air columns 11,
12, 51 have at least one mutual communication.
[0032] As shown in FIG. 2 and FIG. 9, the disclosed
vibration-absorbing air sheath 100 may further include a buffering
piece 7 whose one side is connected to the first buffering wall 1
with the first heat-seal edge 10 through heat sealing, and opposite
side is connected to the second buffering wall 2 with the second
heat-seal edge 20 through heat sealing. Then the bilaterally sealed
buffering piece 7 is partially sealed along the air column lines
111, 211 of the first buffering wall 1 and second buffering wall 2
through heat sealing, so that the buffering piece 7 is hung in the
accommodating space 6, thereby wrapping the object 200 and reducing
its possible movement. It is to be noted that the buffering piece 7
is not sealed to the parts of the air column lines 111, 211 that
correspond to middle sections of the air columns 11 and 21, so as
to make the central part of the buffering piece 7 suspended.
[0033] As shown in FIG. 1 through FIG. 4, according to the
preferred embodiment of the vibration-absorbing air sheath 100, the
accommodating space 6 formed between the first buffering wall 1 and
the second buffering wall 2 by bending the first buffering wall 1
and the second buffering wall 2 has a U-shaped structure with an
upward opening. The U-shaped structure has its two outer ends left
open. Different from the prior art, the disclosed
vibration-absorbing air sheath 100 features that the first
buffering wall 1 and the second buffering wall 2 are first bent and
bound at two ends to form the U-shaped structure, and at each of
two opposite ends of the U-shaped structure, the air column lines
110, 210 are such heat-sealed that an opening 80 is left at their
lower parts and a binding portion 8 is formed, so that the air
columns 11 and 21 outside the binding portion 8 and the third
buffering wall 5 jointly form a triangular end buffering portion.
The air column line 110, 210 bound to form the binding portion 8
are located at inner sides of the second outmost air columns 11 and
21 of the first buffering wall 1 and the second buffering wall 2,
respectively, so that the two ends are closed. The reserved opening
80 has a height determined according to the depth of the
accommodating space 7 occupied by the buffering piece 7, and may be
greater than, equal to or small than the length of the binding
portion 8. The amount of the air column lines 110, 210 that form
the binding portion 8 may match the amount of the air columns 11
and 21 outside the binding portion 8, being one or more than one.
In other words, there may be one or plural said air columns 11 and
one or plural said air columns 21 outside the binding portion
8.
[0034] However, as shown in FIG. 2 through FIG. 4, while the
preferred embodiment is a successful approach to building the
triangular buffering portion 9 by heat-sealing the air columns 110,
210 at the two ends of the U-shaped structure with the opening 80
reserved and the binding portion 8 formed, the triangular buffering
portion 9 has irregular, towering corners formed at the air columns
11, 21 at the two ends of the first buffering wall 1 and the second
buffering wall 2 outside the binding portion 8 and the bent part of
the third buffering wall 5 (as shown in FIG. 18 and FIG. 19). These
corners when receiving squeezes or impacts are likely to have their
air columns 11, 21, 31 bursting, and in turn make the entire
buffering structure at the two ends of the vibration-absorbing air
sheath 100 lose the vibration-absorbing function. Moreover, since
the two ends of the U-shaped structure is closed through heat
sealing according to the present embodiment, the opening edge of
the accommodating space 6 shrinks as the binding portion 8 is
formed. This shrinkage at the two ends can become obstruction when
the object 200 to be placed into the accommodating space 6 is
relatively large and wide. Furthermore, after the two ends of the
U-shaped structure are closed as a result of the formation of the
binding portions 8 through heat sealing, irregular wavy crumples
appear at the open edge of the accommodating space 6 and will
aggravate over time as the vibration-absorbing air sheath 100 is
used. The wavy edge is not only unpleasing in terms of appearance,
but also leads to unbalanced load distribution between the first
buffering wall 1 and the second buffering wall 2 when the object
200 is loaded.
[0035] Please refer to FIG. 5, FIG. 6 and FIG. 10 through FIG. 12.
FIG. 5 is a schematic drawing showing the end buffering portion of
the preferred embodiment of the present invention before the air
columns are bent upward. FIG. 6 is a schematic drawing showing the
end buffering portion of the preferred embodiment of the present
invention after the air columns are bent upward. FIG. 11 is an
enlarged, partial view of a first concept of the preferred
embodiment of the present invention. FIG. 12 is an enlarged,
partial view of a second concept of the preferred embodiment of the
present invention. As shown, for addressing the first issue noted
in the preferred embodiment, the disclosed vibration-absorbing air
sheath 100 may further be improved by adding at least one outward
slanted crease 113 or 213 formed through heat sealing at the lower
part of each of the air columns 11 and 21 outside the binding
portion 8 after the air column lines 110, 210 are bound to form the
binding portion 8. The creases 113, 213 make the air columns 11 and
21 outside the binding portion 8 have their lower parts holding a
pressure greater than that of their upper parts, so the air columns
51 of the third buffering wall 5 outside the binding portion 8 can
be bent upward against the creases 113, 213. In other words, the
lower part of the triangular buffering portion 9 is bent upward
against the creases 113, 213, so as to eliminate the formation of
corners around the triangular buffering portion 9, and make the air
columns 11 and 21 at the upper part of the triangular buffering
portion 9 spread out and form a flat plane, so as to provide a
maximum buffering area for the end buffering portion 9. It is to be
noted that the amount of the air columns 11 and 21 outside the
binding portion 8 having the creases 113, 213 may be one or more
and the amount of the air column 51 of the third buffering wall 5
bent upward may be correspondingly be one or more. In addition, the
creases 113, 213 are inclined on the air columns 11 and 21 outside
the binding portion 8, with an upward trend when extending toward
the outside of the binding portion 8. This facilitates the upward
bending of the air columns 51 of the third buffering wall 5 outside
the binding portion 8. The upward bent air columns 51 push the air
columns 11 and 21 spread out so as to fill the sunken parts of the
first buffering wall 1 and second buffering wall 2 caused by the
formation of the binding portion 8, thereby improving lateral
buffering.
[0036] Please refer to FIG. 7, FIG. 8, FIG. 10, FIG. 11, FIG. 13
and FIG. 14. FIG. 7 is a schematic drawing showing the adjacent air
columns inside the binding portion of the preferred embodiment of
the present invention. FIG. 8 is another schematic drawing showing
the adjacent air columns inside the binding portion of the
preferred embodiment of the present invention. FIG. 13 is an
enlarged, partial view of a third concept of the preferred
embodiment of the present invention. FIG. 14 is an enlarged,
partial view of a fourth concept of the preferred embodiment of the
present invention. As shown, for addressing the second issue noted
in the preferred embodiment, the disclosed vibration-absorbing air
sheath 100 may further be improved by changing the configuration of
the air column lines 111, 211 between the at least two air columns
11, 12 inside the binding portion 8. As shown in FIG. 7 and FIG. 8,
inside the binding portion 8, there are at least two adjacent air
columns of different diameters, namely a first air column 81 and a
second air column 82, so that a width of the accommodating space 6
corresponding to the binding portion 8 is maximized as the first
air column 81 and the second air column 82 jostle with each other.
As shown in FIG. 11, in the first concept of the present
embodiment, the air column line 111a inside and next to the binding
portion 8 has its lower part inclined as the inclined portion 114
of the air column line 111a, so that the air column 11 outside the
upper part of the air column line 111a is smaller than the air
column 11 inside, and the air column 11 outside the lower part is
greater than the air column 11 inside. Thereby, at the upper part
of the air column line 111a, the outside air column 11 has a
pressure smaller than that of the inside air column 11, and at the
lower part of the air column line 111a, the outside air column 11
has a pressure greater than that of the inside air column 11. As
shown in FIG. 13, in the third concept of the present embodiment,
the air column line 111a inside and next to the binding portion 8
has its upper part with a heat-sealed area greater than the of the
lower part, so that the at the upper part of the air column line
111a, the outside air column 11 is smaller than the inside air
column 1, and at its lower part, the outside air column 11 is
greater than the inside air column 11. As a result, the air column
11 outside the upper part of the air column line 111a has a
pressure smaller than that of the inside air column 11. As shown in
FIG. 14, in the fourth concept of the present embodiment, the air
column 11 outside the air column line 111a next to the binding
portion 8 is smaller than the air column 11 inside, so the pressure
of the air column 11 outside the air column line 111a is smaller
than that of the air column 11 inside. With either of the
above-mentioned concepts, the shrinkage at the two ends of the open
edges of the accommodating space 6 caused by formation of the
binding portion 8 can be significantly improved. It is to be noted
that the air column lines 111, 211 inside the binding portion 8 may
each be of an amount of one or more than one. In practice, the
amount may vary according to the amount of the air columns 11 and
21 that have shrinkage. Additionally, the inclined portion 114 of
the first buffering wall 1 and the inclined portion 214 of the
second buffering wall 2 are preferably extended inward as a
downward slope, so as to help the jostle.
[0037] Please refer to FIG. 10, FIG. 11, FIG. 15 and FIG. 16. FIG.
15 is another enlarged, partial view of the first concept of the
preferred embodiment of the present invention. FIG. 16 is an
enlarged, partial view of a fifth concept of the preferred
embodiment of the present invention. As shown, for addressing the
third issue noted in the preferred embodiment, in the disclosed
vibration-absorbing air sheath 100, each of the air column lines
111, 211 between the air columns 11, 12 inside the binding portion
8 has at least one outward inclined upper end 112 or 212. Thereby,
the air pressure in the air columns 11 and 21 can be guided to the
ends through the inclined upper end 112, 212 of the air column line
111, 211. Once all of the air columns 11 and 21 of the first
buffering wall 1 and the second buffering wall 2 are inclined in
the same direction, the open edge of the accommodating space 6 can
be prevented from having an irregular wavy shape as the binding
portion 8 is formed. As shown in FIG. 15, all of the air column
lines 111, 211 between the air columns 11, 21 inside the binding
portion 8 have their upper ends 112, 212 inclined toward either
said end of the vibration-absorbing air sheath 100. Alternatively,
as shown in FIG. 16, a half of the air column lines 111, 211
between the air columns 11, 21 inside the binding portion 8 have
their upper ends 112, 212 inclined toward one said end of the
vibration-absorbing air sheath 100 and the other half have their
upper ends 112, 212 inclined toward the other said end of the
vibration-absorbing air sheath 100. In addition, the air columns 11
of the first buffering wall 1 and the air columns 21 of the second
buffering wall 2 inside the binding portion may have the upper ends
thereof inclined in an identical direction or inclined in opposite
directions, respectively, without limitation.
