PROBLEM TO BE SOLVED: To provide a bag-making device with an automatic nonreturn valve of an air injection port, of a baloon, capable of making a bag with a nonreturn valve at a cheap price without binding after putting air or plugging, owing to that the nonreturn valve is processed at the time of bag-making.SOLUTION: A bag-making device of a bag with a nonreturn valve is such that: a non-adhesive is coated only to a designated position in an inside upper part of a first panel 1 followed by overlapping a second panel thereon, and both sides of the nonadhesive coated part of the first panel are heat-bonded; the second panel is overlapped on a third panel 3 so as to widely heat-bond in a form of connecting the heat adhesive parts of the first panel and the second panel; and the non-adhesive coated part of the first panel 1 becomes an air injection port, and four sides of the first panel, the second panel and the third panel are heat-bonded. There is a case that an adhesive is coated on the non-adhesive coated part of the first panel.SELECTED DRAWING: Figure 1 【課題】バールンの様な風船の、空気注入口の自動逆止弁の製袋装置であって、逆止弁が製袋時に加工してありますので、空気を入れた後結んだり、栓をする必要がなく、逆止弁付き袋が安価に製袋できる。【解決手段】第一パネル１の内側上部に非接着剤を指定位置のみに塗布し、第二パネルを重ね、第一パネルの非接着剤塗布部の両横側を熱接着させる。第二パネルに第三パネル３を重ね、第一パネルと第二パネルの熱接着部を繋ぐ形で広幅熱接着する。第一パネル１の非接着剤塗布部が空気注入口となる、第一パネルと第二パネルと第三パネルの四方を熱接着させた逆止弁付袋の製袋装置。第一パネルの非接着剤塗布部には粘着剤を塗布する事もある。【選択図】図１
