Description
[0001] The entire disclosure of Japanese patent Application No.
2020-125732, filed on Jul. 22, 2020, is incorporated herein by
reference in its entirety.
BACKGROUND
Technological Field
[0002] The present invention relates to a pneumatic cushioning
material, and more particularly to a pneumatic cushioning material
that is inserted into a gap between an article and a packing box
for protection of the article when the article to be packed is
stored in the packing box.
Description of the Related art
[0003] In transportation of articles such as printers, copiers, and
PCs, it is important to protect the articles from vibrations and
shocks during transportation. Due to such a demand for protection
of articles, foamed resin cushioning materials have been mainly
used to fill the gap between the packing box and the articles.
However, it is considered desirable to use a pneumatic cushioning
material from a viewpoint of reducing an environmental load.
[0004] As a conventional pneumatic cushioning material, as
described in JP 2018-131258 A, a material is known that includes
two air cells and in which an intermediate band-shaped portion
exists between the two air cells. An air flow passage is formed
inside the intermediate band-shaped portion,, and the two air cells
communicate with each other through the air flow passage.
[0005] However, in the conventional pneumatic cushioning material,
even if the two air cell parts are fastened to the article with
tape or the like, they are in contact with only two surfaces of the
article. For this reason, in the conventional pneumatic cushioning
material, if the tape fastening one of the air cell parts is peeled
off due to vibration during transportation, the air cell part is
shifted from the article. In this case, in the conventional
pneumatic cushioning material, the tape fastening the other air
cell part is also easily peeled off, and as a result, there has
been a case where the pneumatic cushioning material itself comes
off from the article during transportation.
Summary
[0006] The present invention has been made in view of the
circumstances described above, and an object of the present
invention is to provide a pneumatic cushioning material that does
not easily shift or fail after packing.
[0007] To achieve the abovementioned object, according to an aspect
of the present invention, a pneumatic cushioning material
reflecting one aspect of the present invention comprises: a first
air cell part including at least one air cell containing air; a
second air cell part including at least one air cell containing
air; a third air cell part including at least one air cell
containing air; a first connection that connects the first air cell
part and the second air cell part together; a second connection
that connects the first air cell part and the third air cell part
together, wherein the first connection is bendable by a first
rotation axis, the second connection is bendable by a second
rotation axis, and an angle at which a line segment obtained by
extending the first rotation axis and a line segment obtained by
extending the second rotation axis intersect is in a range of
greater than 0 degrees and less than 180 degrees.

DETAILED DESCRIPTION OF EMBODIMENTS
[0059] Hereinafter, one or more embodiments of the present
invention will be described with reference to the drawings.
However, the scope of the invention is not limited to the disclosed
embodiments. Note that, in the description of the drawings, the
same elements are denoted by the same reference numerals, and
duplicate descriptions will int be provided. Furthermore, for
members having the same shape, reference numerals of sonic members
are omitted. Furthermore, dimensional ratios of the drawings are
exaggerated for convenience of description and may be different
from actual ratios.
First Embodiment
[0060] FIG. 1 is a plan view illustrating a pneumatic cushioning
material of a first embodiment. FIG. 2 is a perspective view
.illustrating the pneumatic cushioning material of the first
embodiment. FIG. 3 is a plan view for explaining dimensions of
respective parts of the pneumatic cushioning material of the first
embodiment. FIGS. 4A and 4B are side views for explaining
dimensions of respective parts of the pneumatic cushioning material
of the first embodiment. FIG. 4A is a side view seen from a
direction of an arrow A in FIG. 3, and FIG. 4B is a side view seen
from a direction of an arrow B in FIG. 3.
[0061] As illustrated in FIGS. 1 and 2, a pneumatic cushioning
material 110 of the first embodiment includes a first air cell part
101, a second air cell part 102, and a third air cell part 103.
[0062] The first air cell part 101, the second air cell part 102,
and the third air cell part 103 each include at least one air cell
100 containing air. The sizes of the air cells 100 in the
respective first air cell part 101, second air cell part 102, and
third air cell part 103 may be the same size or different sizes.
Furthermore, the number of the air cells 100 in each of the first
air cell part 101, the second air cell part 102, and the third air
cell part 103 may be one or a plurality. An embodiment in which a
plurality of air cells 100 is included in one air cell part will be
described in an embodiment described later.
[0063] The first air cell part 101 and the second air cell part 102
are connected together by a first connection 105. The first air
cell part 101 and the third air cell part 103 are connected
together by a second connection 106.
[0064] The first connection 105 and the second connection 106 are
air passages and allow air to flow between the first air cell part
101, the second air cell part 102, and the third air cell part 103.
As a result, when any of the first air cell part 101, the second
air cell part 102, and the third air cell part 103 is compressed,
the pneumatic cushioning material 110 can move air to other air
cells 100, and can prevent the air cell 100 from bursting. However,
the first connection 105 and the second connection 106 do not have
to be air passages.
[0065] The first air cell part 101, the second air cell part 102,
the third air cell part 103, the first connection 105, and the
second connection 106 are all formed on a base sheet 108. The base
sheet 108 is a glue allowance portion when sheet materials are
overlapped to form the air cell 100 and the like. However, the base
sheet 108 (glue allowance portion) does not have to be
provided.
[0066] A material used as the pneumatic cushioning material 110 is,
for example, a synthetic resin such as polyethylene, polypropylene,
or polyvinyl chloride. Preferably, low density polyethylene is
used,
[0067] The first connection 105 between the first air cell part 101
and the second air cell part 102 can rotate at least 90 degrees
around a first rotation axis axr1. Similarly, the second connection
106 between the first air cell part 101 and the third air cell part
103 can rotate at least 90 degrees around a second rotation axis
axr2.
[0068] A line segment (same as axr1 in FIG. 3) obtained by
extending the first rotation axis axr1 and a line segment (same as
axr2 in FIG. 3) obtained by extending the second rotation axis axr2
intersect. An angle ca of the intersecting line segments is in a
range of greater than 0 degrees (not including 0 degrees, the same
applies to other descriptions) and less than 180 degrees.
[0069] In the first embodiment, the angle ca at which the line
segment obtained by extending the first rotation axis axr1 and the
line segment obtained by extending the second rotation axis axr2
intersect is approximately 90 degrees.
[0070] Here, "approximately 90 degrees" is used because, as
described above, a flexible material is used for the pneumatic
cushioning material 110, so that it is difficult to make the angle
exactly 90 degrees in manufacturing. Thus, "approximately 90
degrees" includes manufacturing errors. Hereinafter, "approximately
. . . " has the same meaning.
[0071] With reference to FIGS. 3, 4A and 4B, in the first
embodiment, the dimensions of respective parts of the pneumatic
cushioning material 110 are defined as follows.
[0072] w1: The length in a first direction X of one air cell 100 in
the first air cell part 101.
[0073] h1: The length in a second direction Y of one air cell 100
in the first air cell part 101. Note that, the first direction X
and the second direction Y are substantially orthogonal to each
other.
[0074] w2: The length in the first direction X of one air cell 100
in the second air cell part 102.
[0075] h2: The length in the second direction Y of one air cell 100
in the second air cell part 102.
[0076] w3: The length in the first direction X of one air cell 100
in the third air cell part 103.
[0077] h3: The length in the second direction Y of one air cell 100
in the third air cell part 103.
[0078] i1: The length of the first connection 105.
[0079] i2: The length of the second connection 106.
[0080] T: The thickness of each air cell 100 in the first air cell
part 101, the second air cell part 102, and the third air cell part
103.
[0081] t: The thickness of the first connection 105 and the second
connection 106.
[0082] Note that, the dimensions of the respective parts are the
dimensions when no load is applied to all the air cells 100, the
first connection 105, and the second connection 106.
[0083] In each part, w1 to w3, h1 to h3, and T are any length and
thickness at which the pneumatic cushioning material has a function
as a cushioning material. The i1 and i2 are lengths at which
bending is possible as the first rotation axis and the second
rotation axis. The t is ally thickness at which rotation is
possible around the rotation axis, and t<T.
[0084] FIG. 5 is a perspective view illustrating an example of a
method of fastening the pneumatic cushioning material 110 of the
first embodiment to an article 10.
[0085] The article 10 illustrated in FIG. 5 is a rectangular
parallelepiped. The pneumatic cushioning material 110 is bent 90
degrees on the first rotation axis axr1 and the second rotation
axis axr2.
[0086] That is, as illustrated in FIG. 5, the pneumatic cushioning
material 110 is bent at the first connection 105, and the first air
cell part 101 and the second air cell part 102 come in contact with
surfaces 10a and 10b of the article 10. Furthermore, the pneumatic
cushioning material 110 is bent at the second connection 106, and
the third air cell part 103 comes in contact with a surface 10c of
the article 10.
[0087] FIG. 6 is a perspective view illustrating an example of
another method of fastening the pneumatic cushioning material 110
of the first embodiment to the article 10.
[0088] As illustrated in FIG. 6, in the pneumatic cushioning
material 110, the first air cell part 101 is fastened to the
article 10 with a tape 811, and the second air cell part 102 and
the third air cell part 103 are fastened to be coupled to each
other with a tape 812. In this fastening method, the pneumatic
cushioning material 110 is taped to the article 10 at one place,
and is taped so that the second air cell part 102 and the third air
cell part 103 are coupled to each other.
[0089] The pneumatic cushioning material 110 of the first
embodiment has the following effects.
[0090] The pneumatic cushioning material 110 of the first
embodiment can cover the three surfaces 10a to 10c of a corner of
the article 10 by one pneumatic cushioning material 110. Then,
usually, when the article 10 is put into a cardboard box or the
like, the pneumatic cushioning material 110 is used to fill a gap
between the article 10 and the cardboard box. For this reason, the
pneumatic cushioning material 110 is packed in the gap between the
article 10 and the cardboard box when the article 10 is put into
the cardboard box or the like, so that the pneumatic cushioning
material 110 does not fall or shift due to vibration during
transportation even when not taped.
[0091] Furthermore, the pneumatic cushioning material 110 of the
first embodiment can cover the three surfaces 10a to 10c
constituting the corner of the article 10 by one pneumatic
cushioning material 110. Moreover, when taped, the pneumatic
cushioning material 110 is only required to be taped at two places,
and thus can be easily fastened. As a result, the pneumatic
cushioning material 110 of the first embodiment does not fall or
shift due to vibration during transportation.
[0092] Furthermore, the method of fastening the pneumatic
cushioning material 110 of the first embodiment is not limited to
fastening it at two places, and for example, the first air cell
pail 101 may be fastened at only one place with the tape 811 for
fastening the pneumatic cushioning material 110 to the article 10.
The pneumatic cushioning material 110 of the first embodiment can
be prevented from failing or shifting due to vibration during
transportation even when taped at only one place.
[0093] Furthermore, since the first connection 105 and the second
connection 106 are both air passages, when a load is applied to any
of the first to third air cell parts 101 to 103, air in each air
cell 100 can be released to other air cells 100 to prevent the air
cell 100 from bursting.
[0094] Hereinafter, as second to seventh embodiments, pneumatic
cushioning materials 110 having different shapes and numbers of air
cells 100 in each air cell part will be described. In the second to
seventh embodiments, the description of the same configuration as
that of the first embodiment will be omitted.
Second Embodiment
[0095] FIG. 7 is a plan view illustrating a configuration of a
pneumatic cushioning material 110 of the second embodiment.
[0096] As illustrated in FIG. 7, the pneumatic cushioning material
110 of the second embodiment includes a triangular air cell 100 in
each of a first air cell part 101, a second air cell part 102, and
a third air cell part 103. The number of air cells 100 in each air
cell part is one.
[0097] FIG. 8 is a perspective view illustrating an example of a
method of fastening the pneumatic cushioning material 110 of the
second embodiment to an article 10.
[0098] As illustrated in FIG. 8, in the pneumatic cushioning
material 110 of the second embodiment, similarly to the first
embodiment, the first air cell part 101 and the second air cell
part 102 are bent at the first connection 105, and come in contact
with a surface 10a and a surface 10b of the article 10.
Furthermore, the pneumatic cushioning material 110 is bent at the
second connection 106, and the third air cell part 103 comes in
contact with a surface 10c of the article 10. Similarly to the
first embodiment, the pneumatic cushioning material 110 may or may
not be taped.
[0099] As a result, also in the pneumatic cushioning material 110
of the second embodiment, three surfaces constituting a corner of
the article 10 can be easily covered by one pneumatic cushioning
material 110. In addition, the pneumatic cushioning material 110 of
the second embodiment has the same effect as that of the first
embodiment.
Third Embodiment
[0100] FIG. 9 is a plan view illustrating a configuration of a
pneumatic cushioning material 110 of a third embodiment.
[0101] As illustrated in FIG. 9, the pneumatic cushioning material
110 of the third embodiment includes a triangular air cell 100 in a
first air cell part 101, a quadrangular air cell 100 in a second
air cell part 102, and a circular air cell 100 partially including
a straight side in a third air cell part 103. The number of air
cells 100 in each air cell part is one.
[0102] Although not illustrated, the pneumatic cushioning material
110 of the third embodiment can easily cover three surfaces
constituting a corner of the article 10 by one pneumatic cushioning
material 110, similarly to the first and second embodiments already
described. In addition, the pneumatic cushioning material 110 of
the third embodiment has the same effect as that of the first
embodiment.
Fourth Embodiment
[0103] FIG. 10 is a plan view illustrating a configuration of a
pneumatic cushioning material 110 of a fourth embodiment,
[0104] As illustrated in FIG. 10, the pneumatic cushioning material
110 of the fourth embodiment includes two triangular air cells 100a
and 100b in a first air cell part 101, and a quadrangular air cell
100 in a second air cell part 102 and a third air cell part 103.
The number of air cells 100 in the second air cell part 102 and the
third air cell part 103 is one.
[0105] Although not illustrated, the pneumatic cushioning material
1110 of the fourth embodiment can easily cover three surfaces
constituting a corner of the article 10 by one pneumatic cushioning
material 110, similarly to the first to third embodiments already
described. In addition, the pneumatic cushioning material 110 of
the fourth embodiment has the same effect as that of the first
embodiment.
Fifth Embodiment
[0106] FIG. 11 is a plan view illustrating a configuration of a
pneumatic cushioning material 110 of a fifth embodiment,
[0107] As illustrated in FIG. 11, the pneumatic cushioning material
110 of the fifth embodiment includes four quadrangular air cells
100a to 100d in a first air cell part 101, and a quadrangular air
cell 100 in a second air cell part 102 and a third air cell part
103. The .number of air cells 100 in the second air cell part 102
and the third air cell part 103 is one.
[0108] In the pneumatic cushioning material 110 of the fifth
embodiment, an angle ca at which a line segment obtained by
extending a first rotation axis axr1 and a line segment obtained by
extending a second rotation axis axr2 intersect is less than 90
degrees. By adopting such an angle, the pneumatic cushioning
material 110 of the fifth embodiment can also be applied to the
article 10 having a polygonal body other than a rectangular
parallelepiped.
[0109] Furthermore, the pneumatic cushioning material 110 of the
fifth embodiment can easily cover three surfaces constituting a
corner of the article 10 by one pneumatic cushioning material 110,
similarly to the first to fourth embodiments already described. In
addition, the pneumatic cushioning material 110 of the fifth
embodiment has the same effect as that of the first embodiment.
Sixth Embodiment
[0110] A sixth embodiment is an example of a fastening method
different from that of the first embodiment. A configuration of a
pneumatic cushioning material 110 is the same as that of the first
embodiment.
[0111] FIG. 12 is a perspective view illustrating an example of a
method of fastening the pneumatic cushioning material 110 to an
article 10 as the sixth embodiment.
[0112] As illustrated in FIG. 12, a shape of the article 10 to
which the pneumatic cushioning material 110 is fastened is a
polygonal body. In such a method of fastening to the article 10,
the pneumatic cushioning material 110 is bent approximately 90
degrees at the fast connection 105. On the other hand, the
pneumatic cushioning material 110 is bent at an angle larger than
90 degrees at the second connection 106.
[0113] By adopting such a fastening method, the pneumatic
cushioning material 110 of the sixth embodiment can easily cover
three surfaces constituting a corner of the article 10 by one
pneumatic cushioning material 110, even for the polygonal body. In
addition, the pneumatic cushioning material 110 of the sixth
embodiment has the same effect as that of the first embodiment.
Seventh Embodiment
[0114] FIG. 13 is a plan view illustrating a configuration of a
pneumatic cushioning material 110 of a seventh embodiment.
[0115] As illustrated in FIG. 13, the pneumatic cushioning material
110 of the seventh embodiment includes a quadrangular air cell 100
at each of a first air cell part 101, a second air cell part 102,
and a third air cell part 103. The number of air cells 100 in each
air cell part is one.
[0116] In the pneumatic cushioning material 110 of the seventh
embodiment, in the first connection 105, the second air cell part
102 is obliquely connected to the first air cell part 101. An angle
ca at which a line segment obtained by extending a first rotation
axis axr1 and a line segment obtained by extending a second
rotation axis axr2 intersect is approximately 90 degrees similarly
to the first embodiment.
[0117] FIG. 14 is a perspective view illustrating an example of a
method of fastening the pneumatic cushioning material 110 of the
seventh embodiment to an article 10.
[0118] As illustrated in FIG. 14, a shape of the article 10 to
which the pneumatic cushioning material 110 is fastened is a
polygonal body. When the pneumatic cushioning material 110 of the
seventh embodiment is fastened to such a polygonal article 10, even
if the pneumatic cushioning material 110 is fastened by being bent
by approximately 90 degrees at the first connection 105, no opening
is made between the second air cell part 102 and the third air cell
part 103.
[0119] By adopting such a fastening method, the pneumatic
cushioning material 110 of the seventh embodiment can easily cover
three surfaces constituting a corner of the article 10 by one
pneumatic cushioning material 110, even for the polygonal body. In
addition, the pneumatic cushioning material 110 of the seventh
embodiment has the same effect as that of the first embodiment.
[0120] Hereinafter, other embodiments will be further
described.
Eighth Embodiment
[0121] A pneumatic cushioning material 110 of an eighth embodiment
has a configuration in which an angle ca at which a line segment
obtained by extending a first rotation axis axr1 and a line segment
obtained by ex1ending a second rotation axis axr2 intersect is
greater than or equal to 90 degrees. For this reason, the pneumatic
cushioning material 110 of the eighth embodiment is particularly
suitable for a polygonal object that is not a rectangular
parallelepiped. Thus, in the following description, the pneumatic
cushioning material 110 of the eighth embodiment will be referred
to as a polygonal-application cushioning material 120.
[0122] FIG. 15 is a plan view illustrating a configuration of the
polygonal-application cushioning material 120 of the eighth
embodiment.
[0123] As illustrated in FIG. 15, the polygonal-application
cushioning material 120 of the eighth embodiment includes a first
air cell part 101, a second air cell part 102, and a third air cell
part 103, similarly to the first embodiment. The first air cell
part 101 and the second air cell part 102 are connected together by
the first connection 105. The first air cell part 101 and the third
air cell part 103 are connected together by the second connection
106. Both the first connection 105 and the second connection 106
are air passages.
[0124] However, the first air cell part 101 and tile second air
cell part 102 have one air cell 100. The air cell 100 in the first
air cell part 101 is larger than the air cell 100 of the first
embodiment. Furthermore, the third air cell part 103 includes two
air cells 100a and 100b.
[0125] In the Polygonal-application cushioning material 120 of the
eighth embodiment, a portion where the first connection 105
connecting the first air cell part 101 and the second air cell part
102 together exists has a fan shape. This portion is referred to as
a fan-shaped connection 105a.
[0126] The first connection 105 can rotate at least 90 degrees
around the first rotation axis axr1, similarly to the first
embodiment. Similarly, the second connection 106 can rotate at
least 90 degrees around the second rotation axis axr2.
[0127] In the eighth embodiment, an angle ca at which a hoe segment
obtained by extending a first rotation axis axr1 and a line segment
obtained by extending a second rotation axis axr2 intersect is
approximately 120 degrees.
[0128] That is, in the polygonal-application cushioning material
120 of the eighth embodiment, the angle ca at which the line
segment obtained by extending the first rotation axis and the line
segment obtained by extending tile second rotation axis intersect
is set to be an angle larger than that of the first embodiment by
the fan-shaped connection 105a. Note that, the intersecting angle
ca is different from that of the seventh embodiment described
above.
[0129] In the polygonal-application cushioning material 120 of the
eighth embodiment, the angle ca at which the line segment obtained
by extending the first rotation axis axr1 and the line segment
obtained by extending the second rotation axis axr2 intersect is
set to approximately 120 degrees, whereby the pneumatic cushioning
material 110 can be easily fastened to a polygonal article 10 other
titan the rectangular parallelepiped.
[0130] FIG. 16 is a perspective view illustrating an example of a
method of fastening the polygonal-application cushioning material
120 of the eighth embodiment to the article 10.
[0131] As illustrated in FIG. 16, the polygonal-application
cushioning material 120 is bent at the first connection 105, and
the first air cell part 101 and the second air cell part 102 come
in contact with two surfaces 10a and 10b of the article 10.
Furthermore, the pneumatic cushioning material 110 is bent at the
second connection 106, and the third air cell part 103 comes in
contact with a surface 10c of the article 10. The
polygonal-application cushioning material 120 is bent 90 degrees on
the first rotation axis axr1 and the second rotation axis axr2.
[0132] Note that, although not illustrated, the
polygonal-application cushioning material 120 of the eighth
embodiment may or may not be taped similarly to the first
embodiment
[0133] The polygonal-application cushioning material 120 of the
eighth embodiment has the following effects.
[0134] In the polygonal-application cushioning material 120 of the
eighth embodiment, the first air cell part 101 and the second air
cell part 102 are connected together by a fan-shaped connection
105a. For this reason, even for a polyhedral article 10, the three
surfaces 10a to 10c at the corners of the article 10 can be covered
by one polygonal-application cushioning material 120. For this
reason, even for the polyhedral article 10, the pneumatic
cushioning material 110 does not fall or shift due to vibration
during transportation, similarly to the first embodiment.
[0135] In addition, the polygonal-application cushioning material
120 of the eighth embodiment has the same effect as that of the
first embodiment.
Ninth Embodiment
[0136] FIG. 17 is a perspective view for explaining a pneumatic
cushioning material 110 of a ninth embodiment.
[0137] The pneumatic cushioning material 110 of the ninth
embodiment is based on the first embodiment. In the pneumatic
cushioning material 110 of the ninth embodiment, portions of a base
sheet 108 are separated from each other at a first connection 105
and a second connection 106.
[0138] As illustrated in FIG. 17, in a state where the pneumatic
cushioning material 110 of the ninth embodiment is arranged on an
article 10, a gap is formed at a corner portion of the article
10.
[0139] Thus, in the pneumatic cushioning material 110 of the ninth
embodiment, it is preferable to fix, for example, portions 101a,
102a, and 103a circled by dotted lines in FIG. 17. Fixing may be
performed by being taped, but in the ninth embodiment, a coupling
is provided in the pneumatic cushioning material 110 to fasten the
separated parts.
[0140] FIG. 18 is a plan view illustrating a configuration of the
pneumatic cushioning material 110 of the ninth embodiment.

material 110 of the ninth embodiment, a claw part 311 is provided
on a second air cell part 102 side of a third air cell part 103,
and a hole part 312 is provided on the third air cell part 103 side
of the second air cell part 102. Other configurations are the same
as those in the first embodiment.
[0142] FIG. 19 is a perspective view illustrating an example of a

[0143] As illustrated in FIG. 19, in the pneumatic cushioning
material 110 of the ninth embodiment, the claw part 311 of the
third air cell part 103 is caused to pass through and engaged with
the hole part 312 of the second air cell part 102 in a state of
being arranged on the article 10. In the pneumatic cushioning
material 110 of the ninth embodiment, a first coupling 301 is
configured in a state where the claw part 311 and the hole part 312
are engaged with each other. The claw part 311 has a shape in which
the tip is open in a T shape. It is preferable that the claw pad
311 and the hole part 312 have shapes in which the tip of the
T-shaped claw part 311 can pass through the hole part 312 and the
tip of the claw part 311 is larger than the opening of the hole
part 312.
[0144] FIG. 20 is a plan view illustrating another configuration of
the pneumatic cushioning material 110 of the ninth embodiment.
[0145] As illustrated in FIG. 20, in the pneumatic cushioning
material 110 of the ninth embodiment, claw parts 311 are provided
on a first air cell part 101 side of the second air cell part 102
and the first air cell part 101 side of the third air cell part
103. Moreover, in the pneumatic cushioning material 110 of the
ninth embodiment, hole parts 312 are provided on the second air
cell part 102 side and the third air cell part 103 side of the
first air cell part 101. Other configurations are the same as those
in the first embodiment.
[0146] FIG. 21 is a perspective view illustrating an example of
another method of fastening the pneumatic cushioning material 110
of the ninth embodiment to the article 10.
[0147] As illustrated in FIG. 21, in the pneumatic cushioning
material 110 of the ninth embodiment, in a state of being arranged
on the article 10, the claw part 311 of the second air cell part
102 is caused to pass through and engaged with the hole part 312 of
the first air cell part 101, and the claw part 311 of the third air
cell part 103 is caused to pass through and engaged with the hole
part 312 of the first air cell part 101. In the pneumatic
cushioning material 110 of the ninth embodiment, a second coupling
302 is configured in a state where these claw part 311 and hole
part 312 are engaged with each other. The claw part 311 has a shape
in which the tip is open in a T shape. It is preferable that the
claw part 311 and the hole part 312 have shapes in which the tip of
the T-shaped claw part 311 can pass through the hole part 312 and
the tip of the claw part 311 is larger than the opening of the hole
part 312.
[0148] Note that, in the ninth embodiment, only one of the first
coupling 301 and the second coupling 302 may be provided., or both
may be provided. Furthermore, the minter of fixed portions, that
is, the number of the first coupling 301 and the second coupling
:302 may be one place of a plurality of places.
[0149] The pneumatic cushioning material 110 of the Math embodiment
has the following effects.
[0150] In the pneumatic cushioning material 110 of the ninth
embodiment, the second air cell part 102 and the third air cell
part 103 are coupled to each other by the first coupling 301. As a
result, in the pneumatic cushioning material 110 of the ninth
embodiment, after being installed on the article 10, a shape is
maintained in which a portion between the first air cell part 101
and the second air cell part 102, and a portion between the first
air cell part 101 and the third air cell part 103 are bent.
[0151] Furthermore, in the pneumatic cushioning material 110 of the
ninth embodiment, the first air cell part 101 and the second air
cell part 102, and the first air cell part 101 and the third air
cell pad 103 are coupled to each other by the second coupling 302.
As a result, in the pneumatic cushioning material 110 of the ninth
embodiment, after being installed on the article 10, a shape is
maintained in which a portion between the first air cell part 101
and the second air cell part 102, and a portion between the first
air cell part 101 and the third air cell part 103 are bent.
[0152] Furthermore, in the ninth embodiment, since the first
coupling 301 and the second coupling 302 have a structure in which
the claw part 311 and the hole part 312 are engaged with each
other, coupling is easy and it is possible to prevent them from
being easily separated from each other after the coupling.
[0153] Note that, as already described above, only one of the first
coupling 301 and the second coupling 302 may be used. Furthermore,
although not illustrated, both the first coupling 301 and the
second coupling 302 may be provided.
[0154] Furthermore, regarding a relationship between the claw part
311 and the hole part 312, they are only required to be impositions
on the first air cell part 101 to the third air cell part 103 where
they can be engaged with each other, and it is not limited which
side has the claw part 311 or the hole part 312. Furthermore, the
hole part 312 may be a slit-shaped notch part.
[0155] Moreover, a modification of the coupling will be
described.
[0156] (First Modification of Coupling)
[0157] FIG. 22 is an enlarged perspective view illustrating a first
modification of the first coupling 301. FIGS. 23 and 24 are
enlarged perspective views illustrating a first modification of the
second coupling 302.
[0158] As illustrated in FIG. 22, in the first modification of the
first coupling 301, both the second air cell part 102 and the third
air cell part 103 are provided with respective hook-claw parts 313
that engage with each other. The hook-claw part 313 is a type of
claw part.
[0159] As illustrated in FIG. 23, in the first modification of the
second coupling 302, both the first air cell part 101 and the
second air cell part 102 are provided with respective hook-claw
parts 313 that engage with each other. Similarly, as illustrated in
FIG. 24, both the first air cell part 101 and the third air cell
part 103 are provided with respective hook-claw parts 313 that
engage with each other.
[0160] (Second Modification of Coupling)
[0161] FIG. 25 is an enlarged plan view illustrating a second
modification of the coupling.
[0162] In the second modification of the coupling, the claw part
311 is provided on one side of the air cell parts to be coupled to
each other, and the hole part 312 is provided on the other side. In
the second modification of the coupling, the claw part 311 is
provided in a recess 109 provided in the base sheet 108.
Furthermore, similarly to the ninth embodiment, the claw part 311
has a shape in which the tip is open in a T shape. Furthermore, the
hole part 312 is provided inside the base sheet 108.
[0163] It is preferable that the claw part 311 and the hole part
312 have shapes in which the tip of the T-shaped claw part 311 can
pass through the hole part 312 and the tip of the claw part 311 is
larger than the opening of the hole part 312. Furthermore, also in
this modification, the hole part 312 may be a slit-shaped notch
part.
[0164] The second modification of the coupling configured in this
way can be used for both the first coupling 301 and the second
coupling 302.
[0165] (Third Modification of Coupling)
[0166] FIG. 26 is an enlarged plan view illustrating a third
modification of the coupling. In the third modification of the
coupling, the claw part 311 is provided on one side of the air cell
parts to be coupled to each other, and the claw part 311 is
provided on the other side as well. The claw part 311 is provided
in the recess 109 provided in the base sheet 108. That is, in this
modification, the claw parts 311 are respectively provided on both
of the air cell parts to be coupled to each other. However, the
claw parts 311 are provided so that the positions are slightly
shifted from each other. Similarly to the ninth embodiment, the
claw part 311 has a shape, in which the tip is open in a T shape.
As a result, in the third modification of the coupling, the claw
parts 311 can be engaged with and coupled to each other.
[0167] The third modification of the coupling configured in this
way can be used for both the first coupling 301 and the second
coupling 302.
[0168] (Fourth Modification of Coupling)
[0169] FIGS. 27 and 28 are plan views of the pneumatic cushioning
material 110 for explaining a fourth modification of the
coupling.
[0170] In the fourth modification of the coupling, as illustrated
in FIG. 27, a cut 341 is provided in a portion that is the first
coupling 301 of the second air cell part 102.
[0171] As illustrated in FIG. 28, there is the cut 341 in the
pneumatic cushioning material 110, whereby a sheet piece 342 formed
in the second air cell part 102 can be bent.
[0172] FIG. 29 is a perspective view illustrating a coupled state
by the sheet piece 342.
[0173] As illustrated in FIG. 29, in the pneumatic cushioning
material 110, the sheet piece 342 is bent and overlapped with the
third air cell part 103, in a state of being installed on an
object. In FIG. 28, a portion denoted by a reference numeral 343 is
a portion where the sheet piece 342 is overlapped with the third
air cell part 103.
[0174] The sheet piece 342 is preferably fastened, for example, at
a portion overlapped with the third air cell part 103. For example,
the sheet piece 342 may be taped, or may be pasted together at the
overlapped portion.
[0175] When the sheet piece 342 is pasted at the overlapped
portion, a glue or an adhesive may be applied in advance to either
the sheet piece 342 or the portion 343 where the sheet piece 342
overlaps. A release paper is attached to a surface to which the
glue or the adhesive is applied, and when the pneumatic cushioning
material 110 is installed on an object, the release paper is peeled
off and the sheet piece 342 is pasted. As a result, the second air
cell part 102 and the third air cell part 103 are coupled to each
other by the sheet piece 342 as the first coupling 301.
[0176] The pneumatic cushioning material 110 of the ninth
embodiment, including each modification, has the following
effects.
[0177] In the pneumatic cushioning material 110 of the ninth
embodiment, the parts separated between the air cell parts are
coupled by the first coupling 301 and/or the second coupling 302.
As a result, in the pneumatic cushioning material 110 of the ninth
embodiment, a shape is maintained in which three surfaces of the
article 10 are covered.
[0178] In addition, the pneumatic cushioning material 110 of the
ninth embodiment has the same effect as that of the first

Tenth Embodiment
[0179] FIG. 30 is a perspective view for explaining a
polygonal-application cushioning material 120 of a tenth
embodiment.
[0180] The polygonal-application cushioning material 120 of the
tenth embodiment is based on the eighth embodiment. In the
polygonal-application cushioning material 120 of the tenth
embodiment, portions of a base sheet 108 are separated from each
other at a first connection 105 and a second connection 106.
[0181] For this reason, in a pneumatic cushioning material 110 of
the tenth embodiment, as illustrated in FIG. 30, a gap is formed at
a corner portion of the article 10 in the state of being arranged
on an article 10.
[0182] Thus, in the polygonal-application cushioning material 120
of the tenth embodiment, it is preferable to fix, for example,
portions 101a, 101b, 102a, and 103a circled by dotted lines in FIG.
30, similarly to the ninth embodiment. Fixing may be performed by
being taped, but also in the tenth embodiment, a coupling is
provided in the polygonal-application cushioning material 120 to
fasten the separated parts, similarly to the ninth embodiment.
[0183] FIG. 31 is a plan view illustrating a configuration of the
polygonal-application cushioning material 120 of the tenth

[0184] As illustrated in FIG. 31, in the polygonal-application
cushioning material 120 of the tenth embodiment, a claw part 311 is
provided on a second air cell part 102 side of a third air cell
part 103, and a hole part 312 is provided on the third air cell
part 103 side of the second air cell part 102. Furthermore, in the

[0185] FIG. 32 is a perspective view illustrating an example of a
method of fastening the polygonal-application cushioning material
120 of the tenth embodiment to the article 10.
[0186] In the polygonal-application cushioning material 120 of the
tenth embodiment, the claw part 311 of the third air cell part 103
is caused to pass through and engaged with the hole part 312 of the
second air cell part 102 in a state of being arranged on the
article 10. In the polygonal-application cushioning material 120 of
the tenth embodiment, a first coupling 301 is configured in a state
where the claw part 311 and the hole part 312 are engaged with each
other,
[0187] Furthermore, in the polygonal-application cushioning
material 120 of the tenth embodiment, in a state of being arranged
on the article 10, the claw part 311 of the second air cell part
102 is caused to pass through and engaged with the hole part 312 of
the first air cell part 101, and the claw part 311 of the third air
cell part 103 is caused to pass through and engaged with the hole
part 312 of the first air cell part 101. In the
polygonal-application cushioning material 120 of the tenth
embodiment, a second coupling 302 is configured in a state where
these claw part 311 and hole part 312 are engaged with each
other.
[0188] Note that, also in the tenth embodiment, similarly to the
ninth embodiment, only one of the first coupling 301 and the second
coupling 302 may be provided, or both may be provided. Furthermore,
the number of fixed portions, that is, the number of the first
coupling 301 and the second coupling 302 may be one place or a
plurality of places. Furthermore, the claw part 311 has a shape in
which the tip is open in a T shape. It is preferable that the claw
part 311 and the hole part 312 have shapes in which the lip of the
T-shaped claw part 311 can pass through the hole part 312 and the
tip of the claw part 311 is larger than the opening of the hole
part 312.
[0189] The polygonal-application cushioning material 120 of the
tenth embodiment has the following effects.
[0190] In the polygonal-application cushioning material 120 of the
tenth embodiment, the second air cell part 102 and the third air
cell part 103 are coupled to each other by the first coupling 301.
As a result, in the polygonal-application cushioning material 120
of the tenth embodiment, after being installed on the article 10, a
shape is maintained in which a portion between the first air cell
part 101 and the second air cell part 102, and a portion between
the first air cell part 101 and the third air cell part 103 are
bent.
[0191] Furthermore, in the polygonal-application cushioning
material 120 of the tenth embodiment, the first air cell part 101
and the second air cell part 102, and the first air cell part 101
and the third air cell part 103 are coupled to each other by the
second coupling 302. As a result, in the polygonal-application
cushioning material 120 of the tenth embodiment, after being
installed on the article 10, a shape is maintained in which a
portion between the first air cell part 101 and the second air cell
part 102, and a portion between the first air cell pail 101 and the
third air cell part 103 are bent,
[0192] Furthermore, hi the polygonal-application cushioning
material 120 of the tenth embodiment, since the first coupling 301
and the second coupling 302 have a structure in which the claw part
311 and the hole part 312 are engaged with each other, coupling is
easy and it is possible to prevent them from being easily separated
from each other after the coupling.
[0193] Note that, although not illustrated, only one of the first
coupling 301 and the second coupling 302 may be used.
[0194] Furthermore, regarding a relationship between the claw part
311 and the hole part 312, they are only required to be in
positions on the first air cell part 101 to the third air cell part
103 where they can be engaged with each other, and it is not
limited which side has the claw pad 311 or the hole part 312.
Furthermore, the hole part 312 may be a slit-shaped notch part.
[0195] Moreover, also in the first coupling 301 and the second
coupling 302 of the polygonal-application cushioning material 120
of the tenth embodiment, various modifications of the coupling
described above can be adopted.

[0196] FIG. 33 is a plan view illustrating a configuration of a
pneumatic cushioning material 110 of an eleventh embodiment.
[0197] The pneumatic cushioning material 110 of the eleventh
embodiment is based on the first embodiment. In the pneumatic
cushioning material 110 of the eleventh embodiment, polygonal lines

COMPARATIVE EXAMPLE
[0249] Here, to understand each of the embodiments described above,
a pneumatic cushioning material laving only two air cells will be
described as a comparative example.
[0250] FIG. 47 is a plan view illustrating a configuration of a
pneumatic cushioning material 1000 of the comparative example.
[0251] As illustrated in FIG. 47, in the pneumatic cushioning
material 1000 of the comparative example, a first air cell. 1001
and a second air cell 1002 each containing air are connected
together by a connection 1003. The connection 1003 is an air
passage. The connection allows air to now between the first air
cell 1001 and the second air cell 1002 by the air passage.
[0252] FIGS. 48A and 48B are perspective views illustrating a state
in which the pneumatic cushioning material 1000 of the comparative
example is taped to an article 10.
[0253] The pneumatic cushioning material 1000 is fastened to the
article 10 using tapes 811 and 812. The tape 811 fastens a portion
of the first air cell 1001 to a surface 10c of the article 10. The
tape 812 fastens a portion of the second air cell 1002 to a surface
10b of the article 10. Thus, the pneumatic cushioning material 1000
comes in contact with only the two surfaces of the article 10.
[0254] As illustrated in FIG. 48A, the tape 812 of the pneumatic
cushioning material 1000 may be peeled off due to vibrations or
shocks during transportation.
[0255] As illustrated in FIG. 48B. When the tape 812 is peeled off,
the pneumatic cushioning material 1000 is in a state of being
fastened to the article 10 only with the tape 811 fastening the
first air cell 1001 side.
[0256] In the pneumatic cushioning material 1000 in such a state,
the second air cell 1002 side is shifted from the article 10. If
this state continues, the second air cell 1002 side will sway due
to vibration during transportation, and the first air cell 1001
side may also be peeled off. Then, the entire pneumatic cushioning
material 1000 falls away from the article 10.
[0257] FIG. 49 is a perspective view illustrating a state in which
two pneumatic cushioning materials 1000 of the comparative example
are taped to the article 10.
[0258] As illustrated in FIG. 49, when using two pneumatic
cushioning materials 1000, it is necessary to fasten each of the
two pneumatic cushioning materials 1000 with tapes 811 and 812.
Thus, when using two pneumatic cushioning materials 1000, work is
necessary to tape them at a total of four places.
[0259] FIG. 50 is a perspective view illustrating a state in which
three pneumatic cushioning materials 1000 of the comparative
example are taped to the article 10.
[0260] As illustrated in FIG. 50, when using three pneumatic
cushioning materials 1000, it is necessary to fasten each of the
three pneumatic cushioning materials 1000 with tapes 811 and 812.
Thus, when using three pneumatic cushioning materials 1000, work is
necessary to tape them at a total of six places.
[0261] As illustrated in FIGS. 49 and 50, a plurality of the
pneumatic cushioning materials 1000 is used, whereby two or more
surfaces of the article 10 can be covered. However, a burden of
work for fastening a plurality of places with tapes is not
light.
[0262] Furthermore, although not illustrated, the pneumatic
cushioning material 1000 including two air cells 100 may be used
together with, for example, corrugated cardboard assembled in a
shape coveting three surfaces constituting a corner of the article
10. However, to use such corrugated cardboard, work is necessary
for assembling the corrugated cardboard in advance in a form to
cover the three surfaces constituting the corner of the article 10,
or pasting the pneumatic cushioning material 1000 to the corrugated
cardboard. For this reason, when using such corrugated cardboard, a
lot of work is required. Furthermore, when using corrugated
cardboard, it is necessary to separate a plastic material and a
paper material from a viewpoint of environmental protection, so it
is necessary to separate the pneumatic cushioning material 1000 and
the corrugated cardboard at the time of disposal. For this reason,
when corrugated cardboard is used, another work load may occur at
the time of disposal.
[0263] As described above, the pneumatic cushioning material 1000
of the comparative example can cover only two surfaces of the
article 10 by one piece. Furthermore, when covering the three
surfaces of the article 10, the pneumatic cushioning material 1000
of the comparative example requires a lot of work.
[0264] In this regard, each of the embodiments described above can
cover three surfaces of the article 10 by one pneumatic cushioning
material 110 (including the polygonal-application cushioning
material 120, the same applies hereinafter). Furthermore, the
pneumatic cushioning material 110 of each of the embodiments
described above can be arranged to cover the three surfaces of the
article 10 without being taped. Furthermore, the pneumatic
cushioning material 110 of each of the embodiments described above
does not shift or fall during transportation even if the tape is
peeled off when being taped.
[0265] Furthermore, the pneumatic cushioning material 110 of each
of the embodiments described above can protect the three surfaces
constituting the corner of the article 10 with a simple work
without using corrugated cardboard or the like. For this reason,
since the pneumatic cushioning material 110 of the first embodiment
does not use corrugated cardboard or the like, it is only necessary
to discard the pneumatic cushioning material 110 as a plastic
material at the time of disposal.
[0266] Although the embodiments of the present invention have been
described above, various modifications are possible. In particular,
the configurations of the embodiments can combine their elements
with each other.
[0267] Furthermore, in the embodiment, the shape of each air cell
100 may be an elliptical shape of a circular shape in a plan view,
for example, a rugby ball shape, an egg shape, or a spherical
shape, in addition to the shape described as the embodiment.
[0268] Although embodiments of the present invention have been
described and illustrated in detail, the disclosed embodiments are
made for purposes of illustration and example only and not
limitation. The scope of the present invention should be
interpreted by terms of the appended claims.
[0269] Furthermore, the present invention can be modified in
various ways based on configurations described in the claims, and
these are also within the scope of the present invention.
