Description

図1および図4に示すように、前記切り込み手段36の下流側に離間し、該切り込み手段36でカバー側と物品収納側とに一旦分断した直後に折曲縁部Fbに縁シール部14を形成する縁シール手段40が配設される。縁シール手段40は、切り込み手段36で切り込み形成して分断された折曲縁部Fbを、そのフィルム重合状態を乱すことなく、左右外側縁から内側に向けた前記シール代Ftに相当する幅分について加熱して、重合したフィルムFを溶着している。縁シール手段40は、各折曲縁部Fbで重合するフィルムFを挟む位置に配置された加熱ブロック42,42を備えている。図2(c)に示すように、フィルムFの搬送に伴って折り重なり扁平状になったフィルムFの折曲縁部Fbが、各加熱ブロック42間の隙間を通過することで、そのフィルムFの折り重なり部が溶着される。 As shown in FIGS. 1 and 4, the cutting means spaced downstream of 36, the cutting means 36 edge seal portion 14 to the bent edge portion Fb immediately after once divided into a cover side and the article storage side An edge sealing means 40 is provided. The edge sealing means 40 has a width corresponding to the sealing margin Ft directed inward from the left and right outer edges without disturbing the film polymerization state of the bent edge Fb cut and formed by the cutting means 36. The polymerized film F is welded by heating. The edge sealing means 40 includes heating blocks 42 and 42 arranged at positions sandwiching the film F to be polymerized at each bent edge portion Fb. As shown in FIG. 2 (c), the folded edge Fb of the film F that is folded and flattened as the film F is conveyed passes through the gaps between the heating blocks 42, so that the film F The fold-over portion is welded.
