Description

  The present invention relates to a partition for partitioning the inside of a packaging container, a packaging box, or the like into a plurality of sections, a partition sheet for manufacturing the partition, and a method for manufacturing the partition.

  BACKGROUND ART Conventionally, a partition body and a method of manufacturing the partition body have been known (Patent Document 1).

  As shown in FIG. 9, in the method for manufacturing a partition body described in Patent Document 1, when each of the partition body forming units 28 is vertically stacked, the vertically adjacent partition body forming units 28 are bonded to each other, and The upper surfaces of the folded first adhesive strips 20 and 21 of the substrate 22 of the partition body forming unit 28 and the breakable lines 26 and 27 of the second adhesive strips 24 and 25 at the central portion of the partition plate forming member 23. An adhesive 30 is applied to the upper surface on the right side, and the lower surface of the lower mount 29 of the substrate 22 of the upper partition forming unit 28 is adhered via the adhesive 30.

  Next, the upper mount 31 is bonded to the uppermost partition body forming unit 28 among the respective partition body forming units 28. At this time, between the partition body forming unit 28 and the upper mount 31, the upper surface of the folded first adhesive piece 20 located at the left end of the substrate 22 and the side wall plate located at the right end of the substrate 22 are folded. The upper surface of the first adhesive piece 21, the upper surface of the second adhesive piece 32 located at the left end of the partition plate forming member 23, and the breakable lines 26, 27 of the pair of second adhesive pieces 24, 25 located at the center. An adhesive 30 is applied to and adhered to the upper surface on the right side.

  Lastly, the lower mount 29 and the upper mount 31 are vertically separated from each other while breaking the breakable lines 26 and 27, and the second adhesive pieces 24, 25, 32 and 33 and the partition plates 34, 35 and 36 are separated.
