検討を重ねた結果次の考案に到達した。 For example, inside a medical bag, there is a blood preservation solution,
When liquids such as infusions and physiological saline are sealed and transported, these liquids have been a cause of leakage.
When blood is collected and centrifuged, it cannot withstand the centrifugal force, which can lead to rupture. In order to solve the above problems, the present inventor conducted intensive studies and arrived at the following idea.

Medical bags are formed by clamping sheets 8a and 8b between a sheet pressing section 4, a mold 1 having a mold 2 of a medical bag 15 formed on its surface, and a mold 10 having a flat surface of the sheet pressing section 9. It is something.

以上の金型１，１０によりシート８ａ，８ｂを

への急激な樹脂の突出がなくなる。また溶着後も
クラツクが生じることがない。 When welding the sheets 8a and 8b using the molds 1 and 10 described above, the sheets 8a and 8b are welded as shown in FIG.
When pressing the sheets 8a and 8b, the molten resin that is the constituent material of the sheets 8a and 8b is welded while gradually moving in the direction of the slope 6 from the pressed location, so that there is no sudden protrusion of the resin toward the inner surface. Moreover, no cracks occur even after welding.

（考案の効果） 以上説明したように本考案は内面エツジ５を斜
面６としかつ該斜面６に凹凸７を形成することに
より、 医療用バツグの内面にバリが発生せず残血、
血液の凝固等が生じない。(Effects of the invention) As explained above, in the present invention, by forming the inner surface edge 5 as a slope 6 and forming the unevenness 7 on the slope 6, burrs are not generated on the inner surface of the medical bag and blood remains.
Blood coagulation does not occur.

内面や外面にクラツクが発生しないので、機
械的強度を維持できる。 Since no cracks occur on the inner or outer surface, mechanical strength can be maintained.

シート溶着後の離型性が良い。 Good releasability after sheet welding.

成形後の医療用バツグの形状をフラツトに維
持できる等の実用的に優れた考案である。 This is an excellent practical idea as it allows the shape of the medical bag to be maintained flat after molding.
