An embodiment of the invention will be described with reference to the drawings. In the drawings referred to below, the same or corresponding members are given the same numbers.

(First embodiment)
FIG. 1 is a perspective view schematically showing a transport box according to a first embodiment of the invention. FIG. 2 is a perspective view of a medium-enclosed cushioning member.

As shown in FIGS. 1 and 2, the transport box 1 includes an outer box 5, a fixing member 8, and a buffer 10. As shown in FIG.

The exterior box 5 can pack the package 2 (see FIG. 3). The exterior box 5 is formed in a rectangular parallelepiped shape. The exterior box 5 is made of cardboard, cardboard, soft resin, hard resin, metal, or the like. The outer box 5 has six inner surfaces 5a-5f. Specifically, the six inner surfaces are four inner surfaces 5a to 5d (see FIG. 3) surrounding the perimeter of the package 2, a bottom surface 5e located below the package 2, and a bottom surface 5e above the package 2. It has a top surface 5f located. The exterior box 5 has a box body 5A having five inner surfaces 5a to 5e other than the top surface 5f, and a lid portion 5B having the top surface 5f. The lid portion 5B is configured to be openable and closable with respect to the box body 5A.

The buffer 10 is arranged between the outer box 5 and the package 2 . The buffer 10 has a plurality of medium-enclosed buffer members 100 and 200 . In this embodiment, the buffer 10 has two medium-enclosed buffer members 100 and 200 . Each of the medium-enclosed cushioning members 100 and 200 has a resin sheet welded into a bag shape and a medium (for example, air) enclosed in the resin sheet. The resin sheet preferably has airtightness. In this embodiment, the medium-enclosed cushioning members 100 and 200 have the same structure. Therefore, one of them, the medium-enclosed cushioning member 100, will be described below.

The medium-enclosed cushioning member 100 has a plurality of cushioning portions 110 , 120 , 130 and communication channels 140 , 150 .

The multiple buffers 110 , 120 , 130 have a first buffer 110 , a second buffer 120 and a third buffer 130 . The plurality of cushioning portions 110, 120, 130 are arranged linearly (in one direction). Each cushioning portion 110, 120, 130 has substantially the same shape as each other. Therefore, the first buffer portion 110 will be described below as an example.

The first buffer portion 110 has a bag shape and contains a medium. The first buffer section 110 has at least one buffer chamber 111 and an edge 112 .

At least one buffer chamber 111 contains a medium. In this embodiment, the at least one buffer chamber 111 has five buffer chambers 111 . However, the number of buffer chambers 111 is not limited to five. Each buffer chamber 111 has a shape elongated in one direction. A plurality of buffer chambers 111 are arranged so as to line up in a direction orthogonal to the one direction.

A rim 112 is formed around the buffer chamber 111 . Edge 112 is formed by welding a resin sheet.

The communication passages 140 and 150 allow communication between adjacent buffer portions among the plurality of buffer portions 110 , 120 and 130 . In this embodiment, the medium-enclosed cushioning member 100 includes a first communication channel 140 that communicates the inside of the first cushioning portion 110 and the inside of the second cushioning portion 120 , the inside of the second cushioning portion 120 and the inside of the third cushioning portion 130 . and a second communication channel 150 that communicates with. More specifically, the first communication channel 140 communicates the buffer chamber 111 of the first buffer section 110 with the buffer chamber 121 of the second buffer section 120, and the second communication channel 150 communicates with the buffer chamber 121 of the second buffer section 120. The inside of the buffer chamber 121 of the second buffer portion 120 and the inside of the buffer chamber 131 of the third buffer portion 130 are communicated.

Each of the communication channels 140, 150 is formed between buffer portions adjacent to each other. That is, the direction in which the buffer chambers 111 are adjacent to each other is perpendicular to the direction in which the plurality of buffer portions 110, 120, and 130 are arranged with the communication channels 140 and 150 interposed therebetween.

Each communication channel 140, 150 is configured to be bendable. That is, each of the communication channels 140 and 150 connects the pair of buffer portions so that one of the pair of buffer portions adjacent to each other is allowed to bend with respect to the other.

In this embodiment, each communication channel 140, 150 is curved. The cross-sectional area of each communication channel 140,150 is smaller than the cross-sectional area of each buffer chamber 111,121,131. Therefore, when the medium in each of the buffer chambers 111, 121, 131 passes through the communication channels 140, 150, the medium receives resistance.

As shown in FIG. 1, the medium-enclosed cushioning member 100 is such that the cushioning portions 110, 120, 130 of the medium-enclosed cushioning member 100 are in contact with one of the six inner surfaces 5a to 5f of the outer box 5, and The communication channels 140 and 150 are arranged in the exterior box 5 in a bent state. The same applies to the medium-enclosed cushioning member 200 . That is, the cushioning body 10 has six cushioning portions.

The fixing member 8 is provided on the inner surface of the outer box 5 . In this embodiment, the fixing member 8 is provided on each inner surface 5a to 5f of the outer box 5. As shown in FIG. The fixing member 8 fixes each buffer part 110, 120, 130 to the inner surfaces 5a to 5f of the outer box 5. As shown in FIG. In other words, the fixing member 8 has the function of determining the positions of the medium-enclosed cushioning members 100 and 200 with respect to the outer box 5 . In this embodiment, the fixing member 8 is composed of a band into which the buffer portions 110, 120, 130 can be inserted. However, the fixing member 8 may be configured by other means such as an adhesive member capable of adhering the cushioning portions 110, 120, and 130 to the inner surface of the exterior box 5, or a hook-and-loop fastener.

For example, at least part of the edge of one medium-enclosed cushioning member 100 may be connected to part of the edge of the other medium-enclosed cushioning member 200 . The edges to be connected to each other are selected within a range that enables opening and closing of the lid portion 5B with respect to the box body 5A. For example, in FIG. 1, the edge of the cushioning portion of the medium-enclosed cushioning member 200 that contacts the bottom surface 5e and the edges of the cushioning portions 110, 120, and 130 of the medium-enclosed cushioning member 100 are connected to each other. The edges may be connected to each other by an adhesive member, stapler, hook-and-loop fastener, or the like. may be connected by a locking projection that can be engaged and disengaged from.

Alternatively, the resin sheet forming one buffer chamber of the plurality of buffer chambers in one medium-filled buffer member 100 is connected to the resin sheet forming one buffer chamber of the plurality of buffer chambers in the other medium-filled buffer member 200. may have been In this case, the medium is not enclosed in the portion of the resin sheet that constitutes the buffer chamber.

Next, a case where an external force acts on one surface of the transport box 1 will be described with reference to FIG. For example, when an external force acts on a portion (a portion having an inner surface 5d) in contact with the second buffer portion 120 of the medium-enclosed buffer member 100 in the outer box 5, the medium in the second buffer portion 120 is As indicated by the arrows, it goes to the first buffer section 110 and the third buffer section 130 through the communication channels 140 and 150 . Then, a part of the impact energy due to the external force is consumed by the resistance acting on the medium passing through the communication passages 140 and 150, and the medium is compressed in the first buffer portion 110 and the third buffer portion 130. consumes a portion of the impact energy. Therefore, the package 2 is effectively protected.

FIG. 4 is a plan view schematically showing the configuration of an air mat in a comparative example. The air mat of the comparative example has a body with a bottom wall and four side walls, and a top wall disposed on the body. When the main body of this air mat is manufactured from a rectangular sheet, as shown in FIG. 4, the bottom wall is arranged in the center of the sheet and adjacent to each of the four sides of the bottom wall. After arranging the side walls and erecting each side wall with respect to the bottom wall, the side walls adjacent to each other are connected to each other. In this case, as indicated by diagonal lines in FIG. 4, the four corners of the sheet do not contribute to the formation of the main body, resulting in a low yield.

On the other hand, in the shipping container 1 of the present embodiment, the plurality of cushioning portions 110, 120, 130 are arranged in a straight line, and the communication passages 140, 150 are formed between the adjacent cushioning portions. , the medium-enclosed cushioning member 100, 200 can be efficiently manufactured from a rectangular resin sheet.
