Description
Technical field
The utility model relates to a kind of Turnover Box liquid inner bag.
Background technology
Along with improving constantly of soft package technology, various packaging product arises at the historic moment, traditional flexible package punch (container) be metal bucket or Plastic Drum, transport point takes up space greatly, and packing cost is high, not easily reclaims.In recent years, occurred the pack for liquids made of highstrenghtpiston's film, the folding framework in outside is protected.Shared by foldable frame, transport space is very little, so the traffic cost returned is low, and can Reusability (Turnover Box).Flexible packaging mainly pillow bag and the three-dimensional pack for liquids of current fluid bag.Three-dimensional pack for liquids is normally connected the specification of making needs between two by four films and then burnt goes to the bottom, sanction removes redundance, PE film weld or boiling hot valve time need pad polytetrafluoroethylene and scald cloth, not only having wasted material increases cost but also wastes man-hour and increase operational sequence.
Summary of the invention
The utility model object is to solve the problem, and provides a kind of Turnover Box liquid inner bag, is specifically realized by following technical scheme:
A kind of Turnover Box liquid inner bag, comprise at the bottom of four all sides of longitudinal direction, bag and pkt. flap, longitudinal side of described four all sides of longitudinal direction is in turn connected to form a bag body, and be connected with the base of described bag body at the bottom of described bag, described pkt. flap is connected with the upper limb of bag body; Be that the double-deck PE material of high strength is made at the bottom of described bag body, bag; One side lower part of described bag body is provided with bleeder valve, and the middle part of described pkt. flap is provided with inlet valve, blow off valve.
Described Turnover Box liquid inner bag, it designs further and is, described pkt. flap is made up of the internal layer be fitted and connected mutually and skin, and described internal layer is connected with welding (blanching) with the upper limb of described bag body; Internal layer adopts PE material to make, with liquid comes into contact.The complex film that described skin adopts PE and PET material to make.The PE layer of complex film and internal layer fit.
Described Turnover Box liquid inner bag, its further design be, the triangle that described pkt. flap is converted into insert edge formula inserts edge with it bag body and bag and welds (see figure 3), and leg-of-mutton top exceeds weld seam 4-5cm, gives over to the overlap use of pkt. flap.
Described Turnover Box liquid inner bag, it designs further and is, the edge of described pkt. flap is positioned at the outside of bag body, thus forms four overlaps in the outside of bag body, and described overlap is provided with some circular holes.
Described Turnover Box liquid inner bag, it designs further and is, the width of described overlap is 4-5cm, and the center of either side overlap is provided with a circular hole, 20cm place, the adjacent longitudinal direction of overlap transverse distance two all sides is also respectively arranged with circular hole, so described four overlaps have 12 circular holes.This circular hole is used for fixing of fluid bag and peripheral frame.
Described Turnover Box liquid inner bag, it designs further and is, described bleeder valve is positioned at a longitudinal overcentre 2cm place, base, all sides.
Described Turnover Box liquid inner bag, it designs further and is, described blow off valve is arranged at inlet valve apart from pkt. flap edge 2/3rds distance.
The utility model compared with prior art has the following advantages: be provided with blow off valve at the inlet valve of pkt. flap and lid back gauge 2/3rds place, is beneficial to gas and discharges; Pkt. flap is converted into insert edge formula triangle and inserts edge with it bag body and bag and weld (see figure 3), and simple to operate, minimizing waste of material, reduces costs; Pkt. flap skin adopts the complex film of PET and PE material, so not be used in pad between valve and film when weldering inlet valve and blow off valve to scald cloth, and also need not pad boiling hot cloth during the welding of bag body.Because PE is heat sealable material, and PET is heat-resisting not heat sealable material.Fluid bag is equipped with inlet valve and bleeder valve, makes that charging is easy at utmost reduces liquid residue.Inlet valve and bleeder valve material are PE, can seal with at the bottom of pkt. flap and bag.

Detailed description of the invention
Below in conjunction with Figure of description and embodiment, the utility model is further described.
As shown in Figure 1 and Figure 2, this Turnover Box liquid inner bag to comprise at the bottom of four all sides 5 of longitudinal direction, bag 8 and longitudinal side of pkt. flap 3, four all sides of longitudinal direction 5 be in turn connected to form bag body 9, be connected with the base of bag body at the bottom of bag, pkt. flap 3 is connected with the upper limb of bag body; Be that the double-deck PE material of high strength is made at the bottom of bag body, bag; One side lower part of bag body is provided with bleeder valve 7, and the middle part of pkt. flap is provided with inlet valve 1, blow off valve 2.Bleeder valve is positioned at a longitudinal overcentre 2cm place, base, all sides.Blow off valve is arranged at inlet valve apart from pkt. flap edge 2/3rds distance.
Pkt. flap 3 is made up of the internal layer 31 be fitted and connected mutually and outer 32, and internal layer is connected with the upper limb of bag body; Internal layer adopts PE material to make, the outer complex film adopting PE and PET material to make.
The edge of pkt. flap is positioned at the outside of bag body, thus forms four overlaps 6 in the outside of bag body, is provided with some circular holes in overlap.
The width of overlap is 4-5cm, and the center of either side overlap is provided with a circular hole 4, and 20cm place, the adjacent longitudinal direction of overlap transverse distance two all sides is also respectively arranged with circular hole, so four overlaps have 12 circular holes.Circular hole 4 is convenient to the fixing of bag body and peripheral frame, keeps jumbo bag cubic shape after charging.
The utility model compared with prior art has the following advantages: be provided with blow off valve at the inlet valve of pkt. flap and lid back gauge 2/3rds place, is beneficial to gas and discharges; As shown in Figure 2, pkt. flap is converted into insert edge formula triangle and inserts edge with it bag body and bag and weld, and simple to operate, minimizing waste of material, reduces costs; Pkt. flap skin adopts the complex film of PET and PE material, so not be used in pad between valve and film when weldering inlet valve and blow off valve to scald cloth, and also need not pad boiling hot cloth during the welding of bag body.Because PE is heat sealable material, and PET is heat-resisting not heat sealable material.Fluid bag is equipped with inlet valve and bleeder valve, makes that charging is easy at utmost reduces liquid residue.Inlet valve and bleeder valve material are PE, can seal with at the bottom of pkt. flap and bag.
