Abstract
The utility model discloses a novel multi-layer coextruded polypropylene infusion bag. A liquid pipe is arranged at the front part of an infusion bag; a liquid filling opening is formed in the back part of the infusion bag; the front part of the infusion bag is set as an upper side, and the back part of the infusion bag is set as a lower side; a straight line on which the edge of the front part of the infusion bag is located is set as a horizontal line; parts, which are positioned on the two sides of the liquid pipe, of a pressing part of the front part of the infusion bag are set as shoulder parts; the lower edges, inside the inner cavity of the infusion bag, of the shoulder parts form included angles of 5-20 degrees with the horizontal line. The included angles between the lower edges, inside the inner cavity of the infusion bag, of the shoulder parts and the horizontal line are increased, namely inclination angles of the shoulder parts of the infusion bag are increased, so that production needs can be met and the product quality can be ensured; liquid in the infusion bag can be fully discharged out when the infusion bag is inversely hung for infusion, so that the problem that liquid cannot be discharged out completely from the traditional infusion bag is effectively solved, the utilization ratio of infusion liquid is improved, waste is reduced and cost is reduced.
Description
Technical field
This utility model relates to a kind of transfusion bag, relates in particular to a kind of Novel polypropylene multi-layer co-extrusion infusion bag.
Background technology
Polypropylene multi-layer co-extrusion infusion bag is the transfusion bag that adopts polypropylene multi-layer co-extrusion film production, and polypropylene multi-layer co-extrusion film is take polypropylene as raw material, the more than 2 layers film that adopts coextrusion process to produce, form without binding agent.Polypropylene multi-layer co-extrusion infusion bag because of have tough and tensile transparent, lightweight, thermal resistance is high, high temperature resistant, gas thoroughly/advantage that head is low more and more comes into one's own.
Conventional polypropylene multi-layer co-extrusion infusion bag has been continued to use early stage bag type Design Mode mostly, along with widening of part bag type, in use usually there is medicinal liquid discharge opeing phenomenon not to the utmost in user, meets with repeatly user's complaint, had a strong impact on product quality and enterprise's reputation.The inventor is by existing discharge opeing polypropylene multi-layer co-extrusion infusion bag product to be not to the utmost studied analysis to market, find that polypropylene multi-layer co-extrusion infusion bag bag molded breadth degree is wider, discharge opeing not to the utmost problem is just more outstanding, and liquid all concentrates on bag shoulder, through comparison, find again, these transfusion bag have a common ground, be exactly that shoulder magnitude of inclination is less, almost there is no amplitude, through test, draw, polypropylene multi-layer co-extrusion infusion bag bag type shoulder amplitude is less, is to affect discharge opeing main cause not to the utmost.
Utility model content
The purpose of this utility model is just to provide in order to address the above problem the Novel polypropylene multi-layer co-extrusion infusion bag of the complete discharge opeing of a kind of energy.
This utility model is achieved through the following technical solutions above-mentioned purpose:
The front portion of Novel polypropylene multi-layer co-extrusion infusion bag described in the utility model is provided with liquid pipe, the rear portion of described transfusion bag is provided with liquid feeding mouth, if the front portion of described transfusion bag is top, rear portion is below, if described transfusion bag front edges place straight line is horizontal line, if being positioned at the part of described liquid pipe both sides in the pressing part of described transfusion bag front portion is shoulder, lower limb and the angle between described horizontal line at described transfusion bag inner chamber in described shoulder are 5～20 °.
As preferably, lower limb and the angle between described horizontal line at described transfusion bag inner chamber in described shoulder are 8～15 °; More preferably 12 °.
The beneficial effects of the utility model are:
This utility model is by adding in transfusion bag shoulder at the lower limb of transfusion bag inner chamber and the angle between horizontal line, increase the angle of inclination of transfusion bag shoulder, can meet Production requirement, guarantee product quality, can make again the liquid in transfusion bag can discharge completely when reversal of the natural order of things transfusion, efficiently solve traditional infusion bag discharge opeing problem not to the utmost, improve the utilization rate of transfusion liquid, reduce waste, saved cost.
Accompanying drawing explanation
Fig. 1 is the front view of Novel polypropylene multi-layer co-extrusion infusion bag described in the utility model;
Front view when Fig. 2 is Novel polypropylene multi-layer co-extrusion infusion bag application described in the utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, the front portion 2 of Novel polypropylene multi-layer co-extrusion infusion bag 5 described in the utility model is provided with liquid pipe 1, the rear portion 8 of transfusion bag 5 is provided with liquid feeding mouth 7, if the front portion of transfusion bag 52 is top, rear portion 8 is below, if place, the edge straight line of the front portion 2 of transfusion bag 5 is horizontal line, if being positioned at the part of liquid pipe 1 both sides in the pressing part of the front portion 2 of transfusion bag 5 is shoulder 3, lower limb 4 and the included angle A between horizontal line at the inner chamber of transfusion bag 5 in shoulder 3 are 5～20 °, be preferably 8～15 °, more preferably 12 °.
As shown in Figure 1, the liquid feeding mouth 7 in figure is the afterbody liquid feeding mouth of transfusion bag 5, has advantages of to fill with to be convenient to after liquid hermetically sealedly, and liquid outlet when liquid pipe 1 is mainly used in infusing, also can be used as anterior liquid feeding mouth.The hanging hole 6 of using while also showing transfusion in Fig. 1.
As shown in Figure 2, in use, transfusion bag 5 is arranged in hook (not shown) by hanging hole 6 reversals of the natural order of things, and the liquid of the interior intracavity of transfusion bag 5 is discharged by liquid pipe 1.When soon drained, because the lower limb 4 of inner chamber that is positioned at transfusion bag 5 in shoulder 3 is for being obliquely installed, so liquid can flow to the internal orifice of liquid pipe 1 under its Gravitative Loads, until liquid is discharged completely.
Claims (3)
1. a Novel polypropylene multi-layer co-extrusion infusion bag, the front portion of described transfusion bag is provided with liquid pipe, the rear portion of described transfusion bag is provided with liquid feeding mouth, it is characterized in that: the front portion of establishing described transfusion bag is that top, rear portion are below, if described transfusion bag front edges place straight line is horizontal line, if being positioned at the part of described liquid pipe both sides in the pressing part of described transfusion bag front portion is shoulder, lower limb and the angle between described horizontal line at described transfusion bag inner chamber in described shoulder are 5～20 °.
