Buffer member and buffer member forming material

Abstract

Provided are a buffer member and a buffer member forming material capable of suppressing formation of a corner part at a bent part and enhancing the buffering function as well. A buffer member includes a resin sheet and a medium. The resin sheet includes a plurality of buffer areas (50). Each buffer area (50) includes a first buffer chamber (51), a second buffer chamber (52), and a connecting flowpassage (53). A length of the connecting flow passage (53) in a second direction is smaller than a length of the first buffer chamber (51) and a length of the second buffer chamber (52) in the seconddirection, and the connecting flow passage (53) of one buffer area and the connecting flow passage (53) of an adjacent buffer area are separated from each other in the second direction. The connecting flow passage (53) directs the medium flowing from one buffer chamber into the connecting flow passage (53) to bend in a direction intersecting the first direction, and redirects the medium flowing out of the connecting flow passage (53) to the other buffer chamber to bend in the first direction again.

Description

technical field [0001] The present invention relates to a cushioning member and a cushioning member forming product. Background technique [0002] Conventionally, cushioning members used when packaging objects to be packaged are known. For example, in Japanese Unexamined Patent Publication No. 2013-173553 (hereinafter referred to as "Patent Document 1"), an air cushion (cushion cushion) in which air is sealed in a resin sheet welded in a bag shape is disclosed. member). The air cushion has a plurality of swollen portions partitioned by transverse partitions and welded portions. Each of the inflation parts has an air circulation path and a plurality of partition inflation parts provided continuously in one direction, and the air circulation path connects the partition inflation parts adjacent to each other. Each divided expansion part is divided by the bent welding part, and the air circulation path is defined by the bent welding part. The bent welded portion has a pair o...
