PROBLEM TO BE SOLVED: To provide a method for packaging a manifold by which a connection of components of the manifold can be suppressed from loosening, separating and so on.SOLUTION: A manifold 2 of a protection object is equipped with at least one of a connection between a pipe 4 and a pipe 6 and a connection between the pipe 6 and a container 8, the manifold 2 is stored in a packaging bag 20, and air in the packaging bag 20 is sucked so as to achieve pressure reduction, whereby the packaging bag 20 is crimped to the manifold 2 from both sides thereof. In this method, it is preferable that a ventilation cloth is interposed between the manifold 2 stored in the packaging bag 20 and said packaging bag 20.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2016,JPO&INPIT【課題】マニフォールドの部品同士の接続部の緩み、分離等が抑制されうるマニフォールドの包装方法の提供。【解決手段】包装対象であるマニフォールド2が、管4と管6との接続部、及び、管6と容器8との接続部の少なくとも一方を備えており、上記マニフォールド2を、包装袋20内に収納し、この包装袋20内の空気を吸引して減圧することにより、包装袋20をマニフォールド2にその両側から圧着させる。この方法においては、上記包装袋20内に収納されたマニフォールド2と、この包装袋20との間に、通気用の布を介在させるのが好ましい。【選択図】図2
