Description
- The entire disclosure of Japanese patent Application No. 2020-125732, filed on Jul. 22, 2020, is incorporated herein by reference in its entirety.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- The advantages and features provided by one or more embodiments of the invention will become more fully understood from the detailed description given hereinbelow and the appended drawings which are given by way of illustration only, and thus are not intended as a definition of the limits of the present invention:

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 inFIG. 3 , andFIG. 4B is a side view seen from a direction of an arrow B inFIG. 3 . - As illustrated in
FIGS. 1 and 2 , apneumatic cushioning material 110 of the first embodiment includes a firstair cell part 101, a secondair cell part 102, and a thirdair cell part 103. - The first
air cell part 101, the secondair cell part 102, and the thirdair cell part 103 each include at least oneair cell 100 containing air. The sizes of theair cells 100 in the respective firstair cell part 101, secondair cell part 102, and thirdair cell part 103 may be the same size or different sizes. Furthermore, the number of theair cells 100 in each of the firstair cell part 101, the secondair cell part 102, and the thirdair cell part 103 may be one or a plurality. An embodiment in which a plurality ofair cells 100 is included in one air cell part will be described in an embodiment described later. - The first
air cell part 101 and the secondair cell part 102 are connected together by afirst connection 105. The firstair cell part 101 and the thirdair cell part 103 are connected together by asecond connection 106. - The
first connection 105 and thesecond connection 106 are air passages and allow air to flow between the firstair cell part 101, the secondair cell part 102, and the thirdair cell part 103. As a result, when any of the firstair cell part 101, the secondair cell part 102, and the thirdair cell part 103 is compressed, thepneumatic cushioning material 110 can move air toother air cells 100, and can prevent theair cell 100 from bursting. However, thefirst connection 105 and thesecond connection 106 do not have to be air passages. - The first
air cell part 101, the secondair cell part 102, the thirdair cell part 103, thefirst connection 105, and thesecond connection 106 are all formed on abase sheet 108. Thebase sheet 108 is a glue allowance portion when sheet materials are overlapped to form theair cell 100 and the like. However, the base sheet 108 (glue allowance portion) does not have to be provided. - 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, - The
first connection 105 between the firstair cell part 101 and the secondair cell part 102 can rotate at least 90 degrees around a first rotation axis axr1. Similarly, thesecond connection 106 between the firstair cell part 101 and the thirdair cell part 103 can rotate at least 90 degrees around a second rotation axis axr2. - A line segment (same as axr1 in
FIG. 3 ) obtained by extending the first rotation axis axr1 and a line segment (same as axr2 inFIG. 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. - 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.
- 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. - With reference to
FIGS. 3, 4A and 4B , in the first embodiment, the dimensions of respective parts of thepneumatic cushioning material 110 are defined as follows. - w1: The length in a first direction X of one
air cell 100 in the firstair cell part 101. - h1: The length in a second direction Y of one
air cell 100 in the firstair cell part 101. Note that, the first direction X and the second direction Y are substantially orthogonal to each other. - w2: The length in the first direction X of one
air cell 100 in the secondair cell part 102. - h2: The length in the second direction Y of one
air cell 100 in the secondair cell part 102. - w3: The length in the first direction X of one
air cell 100 in the thirdair cell part 103. - h3: The length in the second direction Y of one
air cell 100 in the thirdair cell part 103. - i1: The length of the
first connection 105. - i2: The length of the
second connection 106. - T: The thickness of each
air cell 100 in the firstair cell part 101, the secondair cell part 102, and the thirdair cell part 103. - t: The thickness of the
first connection 105 and thesecond connection 106. - Note that, the dimensions of the respective parts are the dimensions when no load is applied to all the
air cells 100, thefirst connection 105, and thesecond connection 106. - 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.

FIG. 5 is a perspective view illustrating an example of a method of fastening thepneumatic cushioning material 110 of the first embodiment to anarticle 10. - The
article 10 illustrated inFIG. 5 is a rectangular parallelepiped. Thepneumatic cushioning material 110 is bent 90 degrees on the first rotation axis axr1 and the second rotation axis axr2. - That is, as illustrated in
FIG. 5 , thepneumatic cushioning material 110 is bent at thefirst connection 105, and the firstair cell part 101 and the secondair cell part 102 come in contact withsurfaces article 10. Furthermore, thepneumatic cushioning material 110 is bent at thesecond connection 106, and the thirdair cell part 103 comes in contact with asurface 10 c of thearticle 10. -
FIG. 6 is a perspective view illustrating an example of another method of fastening thepneumatic cushioning material 110 of the first embodiment to thearticle 10. - As illustrated in
FIG. 6 , in thepneumatic cushioning material 110, the firstair cell part 101 is fastened to thearticle 10 with atape 811, and the secondair cell part 102 and the thirdair cell part 103 are fastened to be coupled to each other with atape 812. In this fastening method, thepneumatic cushioning material 110 is taped to thearticle 10 at one place, and is taped so that the secondair cell part 102 and the thirdair cell part 103 are coupled to each other. - The
pneumatic cushioning material 110 of the first embodiment has the following effects. - The
pneumatic cushioning material 110 of the first embodiment can cover the threesurfaces 10 a to 10 c of a corner of thearticle 10 by onepneumatic cushioning material 110. Then, usually, when thearticle 10 is put into a cardboard box or the like, thepneumatic cushioning material 110 is used to fill a gap between thearticle 10 and the cardboard box. For this reason, thepneumatic cushioning material 110 is packed in the gap between thearticle 10 and the cardboard box when thearticle 10 is put into the cardboard box or the like, so that thepneumatic cushioning material 110 does not fall or shift due to vibration during transportation even when not taped. - Furthermore, the
pneumatic cushioning material 110 of the first embodiment can cover the threesurfaces 10 a to 10 c constituting the corner of thearticle 10 by onepneumatic cushioning material 110. Moreover, when taped, thepneumatic cushioning material 110 is only required to be taped at two places, and thus can be easily fastened. As a result, thepneumatic cushioning material 110 of the first embodiment does not fall or shift due to vibration during transportation. - 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 firstair cell pail 101 may be fastened at only one place with thetape 811 for fastening thepneumatic cushioning material 110 to thearticle 10. Thepneumatic 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. - Furthermore, since the
first connection 105 and thesecond connection 106 are both air passages, when a load is applied to any of the first to thirdair cell parts 101 to 103, air in eachair cell 100 can be released toother air cells 100 to prevent theair cell 100 from bursting. - Hereinafter, as second to seventh embodiments,
pneumatic cushioning materials 110 having different shapes and numbers ofair 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. -

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, thepneumatic cushioning material 110 of the fifth embodiment can also be applied to thearticle 10 having a polygonal body other than a rectangular parallelepiped. - Furthermore, the
pneumatic cushioning material 110 of the fifth embodiment can easily cover three surfaces constituting a corner of thearticle 10 by onepneumatic cushioning material 110, similarly to the first to fourth embodiments already described.

-
FIG. 47 is a plan view illustrating a configuration of apneumatic cushioning material 1000 of the comparative example. - As illustrated in
FIG. 47 , in thepneumatic cushioning material 1000 of the comparative example, a first air cell. 1001 and asecond air cell 1002 each containing air are connected together by aconnection 1003. Theconnection 1003 is an air passage. The connection allows air to now between thefirst air cell 1001 and thesecond air cell 1002 by the air passage. -
FIGS. 48A and 48B are perspective views illustrating a state in which thepneumatic cushioning material 1000 of the comparative example is taped to anarticle 10. - The
pneumatic cushioning material 1000 is fastened to thearticle 10 usingtapes tape 811 fastens a portion of thefirst air cell 1001 to asurface 10c of thearticle 10. Thetape 812 fastens a portion of thesecond air cell 1002 to asurface 10 b of thearticle 10. Thus, thepneumatic cushioning material 1000 comes in contact with only the two surfaces of thearticle 10. - As illustrated in
FIG. 48A , thetape 812 of thepneumatic cushioning material 1000 may be peeled off due to vibrations or shocks during transportation. - As illustrated in
FIG. 48B . When thetape 812 is peeled off, thepneumatic cushioning material 1000 is in a state of being fastened to thearticle 10 only with thetape 811 fastening thefirst air cell 1001 side. - In the
pneumatic cushioning material 1000 in such a state, thesecond air cell 1002 side is shifted from thearticle 10. If this state continues, thesecond air cell 1002 side will sway due to vibration during transportation, and thefirst air cell 1001 side may also be peeled off. Then, the entirepneumatic cushioning material 1000 falls away from thearticle 10. -

FIG. 50 is a perspective view illustrating a state in which threepneumatic cushioning materials 1000 of the comparative example are taped to thearticle 10. - As illustrated in
FIG. 50 , when using threepneumatic cushioning materials 1000, it is necessary to fasten each of the threepneumatic cushioning materials 1000 withtapes pneumatic cushioning materials 1000, work is necessary to tape them at a total of six places. - As illustrated in
FIGS. 49 and 50 , a plurality of thepneumatic cushioning materials 1000 is used, whereby two or more surfaces of thearticle 10 can be covered. However, a burden of work for fastening a plurality of places with tapes is not light. - Furthermore, although not illustrated, the
pneumatic cushioning material 1000 including twoair cells 100 may be used together with, for example, corrugated cardboard assembled in a shape coveting three surfaces constituting a corner of thearticle 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 thearticle 10, or pasting thepneumatic 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 thepneumatic 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. - As described above, the
pneumatic cushioning material 1000 of the comparative example can cover only two surfaces of thearticle 10 by one piece. Furthermore, when covering the three surfaces of thearticle 10, thepneumatic cushioning material 1000 of the comparative example requires a lot of work. - In this regard, each of the embodiments described above can cover three surfaces of the

Furthermore, thepneumatic cushioning material 110 of each of the embodiments described above can be arranged to cover the three surfaces of thearticle 10 without being taped. Furthermore, thepneumatic 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. - Furthermore, the
pneumatic cushioning material 110 of each of the embodiments described above can protect the three surfaces constituting the corner of thearticle 10 with a simple work without using corrugated cardboard or the like. For this reason, since thepneumatic cushioning material 110 of the first embodiment does not use corrugated cardboard or the like, it is only necessary to discard thepneumatic cushioning material 110 as a plastic material at the time of disposal. - 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.
- 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. - 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.
