Abstract

PURPOSE:To surely and strongly seal both the ends of a lay-flat tube and leak no liquid at all by a method wherein projected parts are formed on the tube sealing face of a top force and/or of a bottom force. CONSTITUTION:A production mold 1 consists of a top force 2, on the tube sealing face 4 of which projected parts 5 are formed, and a bottom force 3. The height H of the projected part 5 is preferably formed to be 0.2t-0.4t, where (t) represents the thickness of a bag-like main body 12. A lay-flat tube 10 made of polyolefin-based synthetic resin is arranged between the top force 2 and the bottom force 3 so as to pinch the tube 10 under heat in order to melt and weld the tube 10. By being strongly pressed with the projected parts 5, primary welds 16 are produced through the compression of the constitutional material of the tube 10. Further, by being pressed with the tube sealing faces 4, secondary welds 17 are formed at the ends of the tube, resulting in realizing sure and strong sealed parts at both the ends of the tube.

次溶着部１７が形成されている。The medical container 11 is composed of a bag-like main body 12 and an opening 15, and a wall thickness t of the bag-like main body 12 is formed at the end of the bag-like main body 12.
O,5t
A primary welded portion 17 having a wall thickness of (60%) to 0.8t (80%) is formed.

本発明において袋状本体１２の肉厚ｔとは、袋状本体１
２を構成するチューブｔ３、ｔ２を重ね合わせた厚さで
ある。すなわち、１＝１．＋１２である。In the present invention, the wall thickness t of the bag-like main body 12 refers to the wall thickness t of the bag-like main body 12.
This is the thickness of the tubes t3 and t2 that make up the tubes t3 and t2 that overlap each other. That is, 1=1. It is +12.

［発明の効果コ 以上説明したように、本発明は、 チューブの両端部が確実に強固にシールされるので、液
体のリークが皆無で画一的な製品を提供することができ
る。[Effects of the Invention] As explained above, in the present invention, since both ends of the tube are reliably and firmly sealed, it is possible to provide a uniform product with no liquid leakage.
