communication flow paths buffer parts enclosing buffer member 100 has a firstcommunication flow path 140 that communicates an inside of thefirst buffer part 110 and an inside of thesecond buffer part 120, and a secondcommunication flow path 150 that communicates an inside of thesecond buffer part 120 and an inside of thethird buffer part 130. More specifically, the firstcommunication flow path 140 communicates between an inside of thebuffer chamber 111 of thefirst buffer part 110 and an inside of abuffer chamber 121 of thesecond buffer part 120, and the secondcommunication flow path 150 communicates between the inside of thebuffer chamber 121 of thesecond buffer part 120 and an inside of thebuffer chamber 131 of thethird buffer part 130. - Each of the
communication flow paths buffer chambers 111 are adjacent to each other is orthogonal to a direction in which the plurality ofbuffer parts communication flow path - Each of the
communication flow paths communication flow paths - In the present embodiment, each of the
communication flow paths communication flow paths buffer chambers buffer chambers communication flow paths - As illustrated in
FIG. 1 , the mediumenclosing buffer member 100 is disposed in theouter box 5 in a state where each of thebuffer parts enclosing buffer member 100 is in contact with one of the sixinner surfaces 5 a to 5 f of theouter box 5, and thecommunication flow paths enclosing buffer member 200. That is, thebuffer body 10 has six buffer parts. - The fixing
member 8 is provided on an inner surface of theouter box 5. In the present embodiment, the fixingmember 8 is provided on each of theinner surfaces 5 a to 5 f of theouter box 5. The fixingmembers 8 fix therespective buffer parts inner surfaces 5 a to 5 f of theouter box 5. In other words, the fixingmember 8 has a function of determining the position of the mediumenclosing buffer members outer box 5. In the present embodiment, the fixingmember 8 is formed by a band into which thebuffer parts member 8 may be formed by an adhesive member capable of bonding each of thebuffer parts outer box 5, or other means such as a hook-and-loop fastener. - For example, at least a portion of the edge part in one medium enclosing
buffer member 100 may be connected to a portion of an edge part in another medium enclosingbuffer member 200. The edge parts connected to each other are selected within a range where thelid portion 5B can be opened and closed with respect to thebox body 5A. For example, inFIG. 1 , the edge part of the buffer part in contact with thebottom surface 5 e of the mediumenclosing buffer member 200 and the edge part of eachbuffer part enclosing buffer member 100 are connected to each other. Note that the edge parts may be connected to each other by an adhesive member, a stapler, a hook, a loop fastener, or the like, or may be connected to each other by a locking recess provided in one edge part and a locking protrusion provided in the other edge part and engageable with and disengageable from the locking recess. - Alternatively, the resin sheet constituting one of the plurality of buffer chambers in one of the medium
enclosing buffer members 100 may be connected to the resin sheet constituting one of the plurality of buffer chambers in another of the mediumenclosing buffer members 200. In this case, the medium is not sealed in the portion constituting the buffer chamber of the resin sheet. - Next, a case where an external force acts on one surface of the
transport box 1 will be described with reference toFIG. 3 . For example, when an external force acts on a portion (a portion having theinner surface 5 d) of theouter box 5 that is in contact with thesecond buffer part 120 of the mediumenclosing buffer member 100, the medium in thesecond buffer part 120 is directed to thefirst buffer part 110 and thethird buffer part 130 through thecommunication flow paths FIG. 3 . Then, a part of impact energy due to the external force is consumed by the resistance acting on the medium passing through thecommunication flow paths first buffer part 110 and thethird buffer part 130. Therefore, the packedobject 2 is effectively protected. -
FIG. 4 is a plan view schematically illustrating a configuration of an air mat in a comparative example. The air mat of the comparative example has a main body having a bottom wall portion and four side wall portions, and an upper wall portion disposed on the main body. When the main body of the air mat is manufactured from a rectangular sheet, as illustrated inFIG. 4 , the bottom wall portion is disposed at the central portion of the sheet, and a side wall portion is disposed at a position adjacent to each of the four sides of the bottom wall portion, and side wall portions adjacent to each other are connected after each side wall portion is raised with respect to the bottom wall portion. In this case, as indicated by hatching inFIG. 4 , four corners of the sheet do not contribute to formation of the main body, and thus the yield is low. - On the other hand, in the
transport box 1 of the present embodiment, since the plurality ofbuffer parts communication flow paths enclosing buffer members - Further, since the
communication flow paths enclosing buffer members enclosing buffer members inner surfaces 5 a to 5 f of theouter box 5. - Note that in the above embodiment, as illustrated in
FIG. 5 , each of thebuffer parts single buffer chamber - Next, a
transport box 1 according to a second embodiment of the present invention will be described with reference toFIGS. 6 and 7 . Note that in the second embodiment, only portions different from those of the first embodiment will be described, and the description of the same structure, operation, and effect as those of the first embodiment will not be repeated. - In the present embodiment, the
buffer body 10 has three mediumenclosing buffer members enclosing buffer members FIG. 7 , each of the mediumenclosing buffer members buffer parts communication flow path 140. - Also in this embodiment, by combining the three medium
enclosing buffer members buffer members inner surfaces 5 a to 5 f of theouter box 5. - Further, as illustrated in
FIG. 8 , when thelid portion 5B of theouter box 5 is formed by the first lid portion 5B1 and the second lid portion 5B2, thebuffer body 10 may have a mediumenclosing buffer member 100 having three buffer parts and two mediumenclosing buffer members - Alternatively, as illustrated in
FIG. 9 , thebuffer body 10 may have two mediumenclosing buffer members enclosing buffer member 200 is inserted from above thebox body 5A after the packedobject 2 is accommodated in thebox body 5A. - Further, the
communication flow path 140 may have a bent shape as illustrated inFIGS. 10 to 12 , or may have a curved shape as illustrated inFIG. 13 . - Alternatively, the
communication flow path 140 may be formed at a central portion in an orthogonal direction (vertical direction inFIG. 14 ) orthogonal to the direction in which thefirst buffer chamber 111 and thesecond buffer chamber 121 are arranged as illustrated inFIG. 14 , may be formed at both ends in the orthogonal direction as illustrated inFIG. 15 , or may be formed so as to be arranged at intervals along the orthogonal direction as illustrated inFIG. 16 . - Further, as illustrated in
FIG. 17 , thecommunication flow path 140 may be formed in a shape in which a portion gradually narrowed from thefirst buffer chamber 111 toward thesecond buffer chamber 121 and a portion gradually widened are arranged in this order. - It is understood by those skilled in the art that the exemplary embodiments described above are specific examples of the following aspects.
