Described moulding negative line 32 is preferably arranged on the groove on soft transfusion bottle bottle bottle wall 21 outer wall, is conducive to caving in soft transfusion bottle bottle center deformation; Described moulding land 31 is preferably arranged on the groove on soft transfusion bottle bottle bottle wall 21 inwall, is conducive to distortion outside soft transfusion bottle bottle outstanding.Certainly, moulding negative line 32 and moulding land 31 structure and position can exchange, but change in any case, all possess the basic feature of described reserved moulding line of weakness 3: be position the weakest on soft transfusion bottle bottle bottle wall 21; When soft transfusion bottle bottle complete sunken after the structure of formation also substantially identical.
Fig. 4 and Fig. 5 is the citing that bottle wall 21 arranges some reserved moulding line of weakness 3 specific embodiments, and number and the location schemes change of concrete moulding negative line 32 and moulding land 31 when implementing are more, repeat no more herein.But during concrete enforcement, the number of preferred moulding negative line 32 and moulding land 31 is all greater than 2, and moulding negative line 32 is identical with the number of moulding land 31, moulding negative line 32 and the distribution of moulding land 31 interval adjacent symmetric.
As shown in Figure 1: described reserved moulding line of weakness 3 is set to coherent moulding line, namely described reserved moulding line of weakness reaches bottle plug 4 position by 22 extensions that link up at the bottom of contiguous bottle on soft transfusion bottle bottle, is not middlely interrupted.Certainly, described reserved moulding line of weakness 3 also can be set to be interrupted moulding leading line, namely on soft transfusion bottle bottle by 22 to be interrupted to bottle plug 4 position to arrange and describedly to reserve moulding line of weakness 3 at the bottom of contiguous bottle.
Described reserved moulding line of weakness 3 is set to be interrupted moulding leading line meaning be: the bottle wall 21 of described reserved moulding line of weakness 3 discontinuity adds the intensity of described reserved moulding line of weakness 3, for uprightly providing more stable support force before described soft transfusion bottle bottle transfusion.
As shown in FIG. 6 and 7: the described reinforcement 24 forming residual air cavity 6 when arranging transfusion from moulding soft transfusion bottle 22 positions at the bottom of contiguous bottle for resisting atmospheric pressure, described reinforcement 24 is only arranged at the bottle wall 21 of at the bottom of contiguous bottle 22.Fig. 6 is state before transfusion, state when Fig. 7 is infusion-completed.Only arrange two described reserved moulding line of weakness 3 in the present embodiment, setting position is with Fig. 2 and Fig. 3, and on described reserved moulding line of weakness 3 extended line, at the bottom of contiguous bottle, 22 positions arrange reinforcement 24.The thickness of described reinforcement 24 is preferably greater than bottle wall 21, and the multiple tension force of the elasticity relying on self larger can provide stronger supporting role.When in soft transfusion bottle bottle, transfusion 5 is discharged, the bottle wall 21 that can support at the bottom of contiguous bottle 22 forms described residual air cavity 6, could not expellant gas during accommodation soft transfusion bottle bottle fill transfusion 5.The reinforcement 24 that length is suitable can provide the residual air cavity 6 of suitable size, makes the volume of residual air cavity 6 slightly larger than could not expellant gas volume at one atm during soft transfusion bottle bottle fill transfusion 5.So, when transfusion 5 is totally lost, gas residual during fill in soft transfusion bottle bottle under atmospheric malleation and liquid-transport pipe-line water column suction function can not enter infusion pipeline.The concrete length of reinforcement 24 need adjust decision according to the amount of residual gas during fill: during fill, residual gas is more, and reinforcement 24 is longer; During fill, residual gas is fewer, and reinforcement 24 is shorter; If later stage canning line technique improves, there is no residual gas during fill, do not need to arrange reinforcement 24.
The support force that the reinforcement 24 that when making that in soft transfusion bottle bottle, transfusion 5 is all totally lost by the setting of reinforcement 24, the multiple tension force of elasticity is larger provides can resist the pressure of water column in atmospheric pressure and liquid-transport pipe-line, and during fill, residual gas all resides in residual air cavity 6.When remaining the fill in air cavity 6 when changing fluid infusion in time, residual gas can not enter infusion pipeline, just need not carry out the bleeding of infusion pipeline when again changing fluid infusion.
At the position away from reinforcement 24, described reserved moulding line of weakness 3 normally can play its effect, forms each bottle wall 21 being reserved moulding line of weakness 3 decile and be close to overlapping structure after infusion-completed.Owing to have employed the embodiment (being only provided with reserved moulding line of weakness 3 at the both ends of soft transfusion bottle bottle major cross-sectional axis) of Fig. 2 and Fig. 3 in Fig. 6 and Fig. 7 embodiment, all form similar double bottle wall 21 at the cross section of each plane (at the bottom of bottle 22 and bottle plug 4 except) of soft transfusion bottle bottle after infusion-completed and be close to overlapping " one " character form structure, just less in bottleneck infundibulum 23 size, slightly large in the middle part of soft transfusion bottle bottle; As shown in Figure 7: A1, A2, A3 and A4 be bottle wall sunken after at each level cross-sectionn figure.
If have employed the embodiment of Fig. 4 and Fig. 5 in Fig. 6 and Fig. 7 embodiment, having infused, rear soft transfusion bottle bottle bottle wall 21 is sunken can form following structure: soft transfusion bottle bottle at the bottom of bottle 22 and bottle plug 4 go out bulge give prominence to, all form similar double bottle wall 21 at the cross section of each plane (at the bottom of bottle 22 and bottle plug 4 except) of soft transfusion bottle bottle and be close to overlapping " ten " character form structure, just less in bottleneck infundibulum 23 size, slightly large in the middle part of soft transfusion bottle bottle.
Certainly, described reserved moulding line of weakness 3 number can change, but all form similar structures: soft transfusion bottle bottle at the bottom of bottle 22 and bottle plug 4 go out bulge give prominence to, the structure that similar double bottle wall 21 is close to overlapping sunken rear formation is all formed at the cross section of each plane (at the bottom of bottle 22 and bottle plug 4 except) of soft transfusion bottle bottle, just less in bottleneck infundibulum 23 size, slightly large in the middle part of soft transfusion bottle bottle, repeat no more herein.
In fact, reinforcement 24 can form irregular lacuna with reserved moulding line of weakness 3 junction, belongs to a part for residual air cavity 6.In a particular embodiment, reply reinforcement 24 length accurate adjustment, reach transfusion 5 in soft transfusion bottle bottle can be totally lost completely fill simultaneously time residual gas can not enter the effect of infusion pipeline.
During concrete enforcement, at the bottom of bottle, 22 other positions arrange reinforcement 24 and form suitable residual air cavity 6; Or only increase the intensity of 22 position bottle walls 21 at the bottom of contiguous bottle, reinforcement 24 is not set, forms suitable residual air cavity 6; Or the length only shortening reserved moulding line of weakness 3 utilizes soft transfusion bottle bottle natural resiliency to form suitable residual air cavity 6 to be feasible program, to repeat no more herein.
In a word: this utility model reaches object without the need to using air inlet needle the transfusion 5 in soft transfusion bottle bottle can be totally lost completely by arranging reserved moulding line of weakness 3 at the bottle wall 21 of soft transfusion bottle bottle; By the setting of reinforcement 24, when making infusion-completed, residual gas can not enter infusion pipeline.So, avoid the operation that air inlet needle inserts bottle plug 4, do not use air inlet needle transfusion 5 also can be totally lost, if fluid infusion could not be changed in time also need not be exhausted operation to infusion pipeline.Structure is simple, very easily implements, safe and reliable.
