Description

  The present invention relates to a sheet set and a support member sheet.

  As a packaging box sheet, a corrugated cardboard sheet having four side panels that form a square cylindrical part at the time of assembly is used. A packaging box formed by assembling the packaging box sheet is widely used for storage of articles, transportation, and the like.

  On the other hand, when an article is stored in the packaging box, the size of the article may be smaller than the size of the packaging box. In this case, a support member may be used to suppress wobbling of the article in the packaging box when the article is accommodated in the packaging box. Further, as such a support member and a packaging box provided with the support member, for example, “a returnable box and a support used therein” (see JP 2006-306469 A) have been proposed.

  The returnable box described in this publication is configured in an annular shape so that the support (support member) surrounds the side surface of the article. Therefore, it is considered that this returnable box can suppress the wobble of the articles accommodated therein.

  However, according to the returnable box described in this publication, since the entire side surface of the article is covered with the support, it is difficult to take out the article easily. Moreover, since this support body is formed by bending a flat sheet along the slit and further expanding the slit, the forming operation is relatively complicated.
