The following explanation opening and closing operations 40a of section, upper and lower end parts 42a, the 42b of 40b, 43a, the 43b effect after

heating region

52a, 52b, 53a, 53b seal as described above.

In order to compare, Fig. 9 A with shown in Fig. 9 B on the heating region different from the present invention, utilize heat-sealing to be fixed on example on the soft resin sheet material 20a upper end 42a of the 40a of opening and closing operations section.

Heating region 102a shown in Fig. 9 A has the essentially rectangular shape, and it is configured in the inboard of comparing with

side edge

46a, 46b with the terminal edge 48a of the upper end 42a of the 40a of opening and closing operations section.Thereby this heating region 102a is different from the heating region of present embodiment, does not comprise the 40a of opening and closing operations section and terminal edge 48a central part 41a opposition side (that is, not satisfying first condition).In addition, the neighboring of heating region 102a does not intersect (that is, not satisfying second condition) with side edge 46a, the 46b of the width both sides of the 40a of opening and closing operations section.

On the other hand, the heating region 112a shown in Fig. 9 B has the essentially rectangular shape of the upper end 42a that exceeds the 40a of opening and closing operations section.Thereby the heating region of this heating region 112a and present embodiment similarly comprises the 40a of opening and closing operations section and terminal edge 48a central part 41a opposition side (that is, first condition).But, different from the heating region of present embodiment, intersection point P12a, P12b place between side edge 46a, the 46b of the width both sides of the neighboring of heating region 112a and the 40a of opening and closing operations section, the neighboring of heating region 112a is with respect to the length direction vertical (that is, not satisfying second condition) of the 40a of opening and closing operations section.

If the heating region 102a shown in Fig. 9 A in this wise, heating region does not comprise the 40a of opening and closing operations section and terminal edge 48a central part 41a opposition side, and the terminal edge 48a of the 40a of opening and closing operations section breaks away from soft resin sheet material 20a with regard to not fitting tightly with soft resin sheet material 20a.Thereby exist terminal edge 48a to scrape operator's skin etc. and the hands sense of touch of medical flexible container descends or aesthetic property is poor and sensation is cheap or quality reduces problem.To this, in the present invention, shown in Fig. 7 A, heating region 52a comprises the 40a of opening and closing operations section and whole (first conditions) terminal edge 47a central part 41a opposition side.Thereby terminal edge 48a and soft resin sheet material 20a fit tightly, and therefore can eliminate the problems referred to above.

In addition, whole (first conditions) that comprise the terminal edge 47a of the 40a of opening and closing operations section by heating region 52a, thus the upper end 42a of the 40a of opening and closing operations section is heat-sealed zone on soft resin sheet material 20a, be that the overlapping region of heating region 52a and upper end 42a becomes large.Thereby, can guarantee easily that the 40a of opening and closing operations section is with respect to the installation strength of necessity of soft resin sheet material 20a.

On the other hand, if the heating region 112a shown in Fig. 9 B in this wise, at intersection point P12a, P12b place, the neighboring of heating region does not tilt with respect to the length direction of the 40a of opening and closing operations section, then can produce following problem.Namely, after inserting finger among the insertion path 45a at the 40a of opening and closing operations section as shown in Figure 5 and Figure 6, make peristome 22 openings, perhaps inserted in inserting path 45a under the state of finger when injecting liquid object to medical flexible container 1, the upper effect of the central part 41a of the 40a of opening and closing operations section is peeled off the such external force of central part 41a from soft resin sheet material 20a.When seeing perpendicular to the direction of soft resin sheet material 20a, this external force in most cases acts on the direction that the length direction with respect to the 40a of opening and closing operations section tilts.If shown in Fig. 9 B at intersection point P12a, P12b place, the neighboring of heating region 112a is vertical with respect to the length direction of the 40a of opening and closing operations section, then the external force of above-mentioned incline direction will act on intersection point P12a, the P12b partly, intersection point P12a, P12b upper stress are concentrated, and can be created in the problem that intersection point P12a, the soft resin sheet material 20a of P12b place break in the worst situation.Relative therewith, in the present invention, shown in Fig. 7 A, at intersection point P12a, P12b place, the neighboring of heating region 52a is with respect to the length direction inclination (second condition) of the 40a of opening and closing operations section.Thereby the external force of above-mentioned incline direction is with regard on regional A1, the A2 on the neighboring that acts on dispersedly the heating region 52a that comprises intersection point P12a, P12b.Thereby, can not produce the large stress concentration as Fig. 9 B, can prevent the situation that soft resin sheet material 20a breaks.

In above-mentioned, be illustrated as example with respect to the effect of the upper end 42a of the 40a of opening and closing operations section take the heating region 52a shown in Fig. 7 A, but for

other heating regions

52b, 53a, 53b too.

In the present embodiment, heating region 52a, the 52b that satisfies first condition and second condition, the heat-sealing of 53a, 53b (with reference to Fig. 7 A, Fig. 7 B, Fig. 8 A, Fig. 8 B) are followed in utilization, with all being fixed on the flexible bag parts 20 of upper and lower end parts 42a, the 42b of the 40a of opening and closing operations section, 40b, 43a, 43b.But the present invention is not limited to this.That is, in the present invention, as long as will by heat-

sealing fixing end

42a, 42b, at least one among 43a, the 43b, utilize the heat-sealing of following the heating region that satisfies first condition and second condition to be fixed and get final product.Preferably follow the heat-sealing of the heating region that satisfies first condition and second condition to be fixed upper end 42a and/or upper end 42b utilization.This is because

upper end

42a, 42b act on the weight of the liquid object of injecting in the medical flexible container 1 easily, and produce easily the illustrated stress concentration of Fig. 9 B.

In the present embodiment,

formation heating region

52a, 52b, 53a, the roughly circular arc 52a1 of 53b, 52b1,53a1,53b1 must not be the certain proper circular arcs of curvature.So long as get final product at the central part 41a of the 40a of opening and closing operations section, 40b, the curve of 41b one side projection, its curvature also can change.For example, also can be an oval part etc.

In addition,

formation heating region

52a, 52b, 53a, line segment 52a2, the 52b2 of 53b, 53a2,53b2 must not be proper straight lines, can comprise the parts such as bending or warpage yet.
