Abstract
The utility model provides a liquid storing container. Even if internal liquid flows greatly, flexible films of a flexible bag body will not be damaged. Compared with the outer peripheral part formed by hot melting flexible films (220a, 220b) through a leading-out component (230), there are not provided with reinforcing effects produced by the high-rigidity leading-out component (230) on short edges of a flexible bag body (221), an outer peripheral part formed by directly hot melting the flexible films (220a, 220b), or on an outer peripheral part formed by hot melting the flexible films (220a, 220b) together with flexible films (220c, 220d). Therefore, endurance of broken bags is relatively lower when the flexible bag body (221) is deforming. Thus, reinforcing welding parts (220e, 220f) are arranged on one short edge of the leading-out component (230) arranged on the flexible bag body (221), and on all corner parts between two long side edges connected with the short edge, so the reinforcing welding parts (220e, 220f) are used for reinforcing the intensity of welding parts.

But, in the minor face of flexible bag 221, in the outer peripheral edge portion forming across derivation member 230 thermal welding flexible film 220a, 220b, owing to utilizing the derivation member 230 higher than the rigidity of flexible film 220a, 220b to strengthen intensity, the patience of the broken bag during therefore for flexible bag 221 distortion etc. is higher.
On the other hand, in the outer peripheral edge portion that in the outer peripheral edge portion forming at direct heat welding flexible film 220a, 220b or together thermal welding flexible film 220a, 220b and flexible film 220c, 220d form, owing to not utilizing the derivation member 230 that rigidity is high to strengthen, the patience of the broken bag during therefore for flexible bag 221 distortion etc. is lower.
Therefore, in the liquid accommodating container 220 of present embodiment, on the minor face of flexible bag 221, in order to strengthen outer peripheral edge portion that direct heat welding flexible film 220a, 220b form or thermal welding flexible film 220a, 220b and flexible film 220c, 220d form together outer peripheral edge portion, being provided with of flexible bag 221, on each bight between two long sides of deriving the minor face of member 230 and being connected with this minor face, be provided with reinforcement weld portion 220e, 220f.

Specifically, as shown in the instruction diagram of Figure 11, strengthen weld portion 220e, 220f except respectively by the minor face of above-mentioned flexible bag 221 (minor face) and this both sides encirclement of long side, hypotenuse 220g, the 220h, inner side edge 220i, 220j and bent limit 220k, the 220l that are also positioned at respectively the inner side of flexible bag 221 surround, as shown in the oblique line part in Figure 11, form close to trapezoidal shape.
In addition,, in the liquid accommodating container 220 of the 2nd embodiment, angulation between hypotenuse 220g, 220h and the long side of flexible bag 221 is made as to angle θ 1.This angle θ 1 being set as making being positioned to imaginary intersection point P1 on the extended line of hypotenuse 220g, 220h is positioned at than clipping and derives part that the outer peripheral edges of member 230 welding flexible film 220a, 220b the form such value in position in the inner part.
In the liquid accommodating container 220 of the present embodiment forming as described above, China ink (not shown) in flexible bag 221 moves to hot melt while being connected to a short brink of deriving member 230, and the flexible film 220a, the 220b that derive near member 230 are out of shape in the mode bloating.So because the China ink moving in the flexible bag 221 of a short brink flows towards the intersection point P1 of above-mentioned hypotenuse 220g, 220h, it is upper and it is applied to larger stress that therefore China ink concentrates on this intersection point P1.
Because this intersection point P1 is positioned at welding flexible film 220a than flexible bag 221, outer peripheral edges that 220b forms by the position of the inner side of bag, even if therefore flexible film 220a, 220b distortion, can not concentrate stress that effect larger the weld of flexible film 220a, the 220b departing from, distortion degree of freedom is less at the intersection point P1 from hypotenuse 220g, 220h yet.
At this, with reference to the position of intersection point of hypotenuse 220g, 220h liquid accommodating containers 220 different with the liquid accommodating container of present embodiment 220, Figure 12 and Figure 13, relatively put on the welding flexible film 220a of flexible bag 221, the stress of outer peripheral edge portion (weld) that 220b welding forms.
First, in the liquid accommodating container 220 shown in Figure 12, the intersection point P2 of hypotenuse 220g, 220h is positioned in the welding flexible film 220a of flexible bag 221, outer peripheral edges that 220b forms.Therefore,, while making China ink (not shown) in flexible bag 221 flow to intersection point P2 when flexible film 220a, 220b distortion, on the weld of the flexible film 220a, the 220b that overlap with intersection point P2, concentrate and act on larger stress.
Then,, in the liquid accommodating container 220 shown in Figure 13, the intersection point P3 of hypotenuse 220g, 220h is positioned in the welding flexible film 220a of flexible bag 221, outer peripheral edges that 220b forms or is positioned at the position by the outside of bag than outer peripheral edges.Therefore, while making China ink (not shown) in flexible bag 221 flow to intersection point P3 when flexible film 220a, 220b distortion, concentrate the stress that effect is larger being positioned on weld on the not shown black path of extending towards intersection point P3, flexible film 220a, 220b.
So, in the liquid accommodating container 220 shown in Figure 12 and Figure 13, the not shown Mo Junhui moving towards intersection point P2, the P3 of hypotenuse 220g, 220h concentrates the stress that effect is larger on the weld of flexible film 220a, 220b respectively.
With respect to this, in the liquid accommodating container 220 shown in Figure 11, the not shown China ink moving towards the intersection point P1 of hypotenuse 220g, 220h flexible film does not arrive the weld of flexible film 220a, 220b.Therefore, on the weld of flexible film 220a, 220b, can not concentrate the stress that effect is larger.
; the liquid accommodating container 220 of the present embodiment shown in Figure 11; by strengthening weld portion 220e, 220f, form the intersection point P1 of hypotenuse 220g, 220h is positioned at than the weld of flexible film 220a, 220b such shape in the inner part; thereby compare with the liquid accommodating container 220 of Figure 12 and Figure 13; the China ink that can reduce to move in inside puts on the stress of the weld of flexible film 220a, 220b, makes weld be difficult to fracture.
