For optimizing technique scheme, the concrete measure of taking also comprises:

In above-mentioned pack for liquids, be provided with lacing wire, lacing wire is fixed on bag with it and adjacent lacing wire side connects successively.

The length of above-mentioned lacing wire is less than the length of bag body. Be the upper end of lacing wire lower than the upper end of bag body, the lower end of lacing wire is higher than the lower end of bag body.

Example one: above-mentioned bag is as square body bag, and pkt. flap is also square, and correspondingly, lacing wire quantity is four, is fixed on bag center line of the each side of body; The outer membrane of pkt. flap is PET and PE composite material film, and the inner layer film of pkt. flap is PE film, outside the PET of outer membrane faces, in the PE of outer membrane faces, is welded on it bag together with inner layer film.

Example two: above-mentioned bag is as circular bag, bag is as double-deck PE cylinder film, bag body bottom transverse front cover road, two ends form wedge angle, two wedge angle bendings are inserted in the base plate in turnover casing, and the outer membrane of pkt. flap and inner layer film are PE film, and the outer membrane of pkt. flap is quadrangular membrane, inner layer film is circular membrane, and outer membrane is welded on it bag together with inner layer film.

Above-mentioned overlap and liner plate are fitted fixing by mightiness belt.

Above-mentioned valve port scalds the center at pkt. flap.

Above-mentioned turnover casing is powerful carton or plastic box.

Flexible package punch structure of the present invention, for substituting existing filling metal bucket, primary structure comprises turnover casing, is arranged in liner plate, base plate and the pack for liquids of turnover casing, and pack for liquids can the side's of being body bag can be also circular bag, and chemical liquid is from the packaging bag of valve port filling liquid. On the pkt. flap of pack for liquids, overlap is set, overlap and liner plate are fixed, and bottom and the base plate of pack for liquids are fixed, and these arrange the steadiness that has greatly improved pack for liquids, and pack for liquids can not rocked in turnover casing. Lacing wire is set in pack for liquids and can strains a bag body, prevent a bag body bulging distortion. Pack for liquids of the present invention is easy to reclaim, and solves cleaning problem, can greatly reduce costs.

Detailed description of the invention

Below in conjunction with accompanying drawing, embodiments of the invention are described in further detail.

The first embodiment: as shown in Figure 1 to Figure 2,

The flexible package punch structure of a kind of 200L, comprise turnover casing and be placed on pack for liquids 1 in turnover casing, that volume is 200L, fluid bag is made up of bilayer or multilayer PE film, bag body 3 side's of being body bags, pkt. flap 2 is also square structure, lacing wire 6 quantity are four, be fixed on the center line of bag body 3 each sides, and adjacent lacing wire 6 sides connect successively, and lacing wire 6 can be strained a bag body, prevent a bag body bulging distortion. Pkt. flap 2 is made up of two films of size, and outside, membranelle is interior for large film, and large stretch of film exceedes small pieces film 8cm, and the overlap exceeding is attached on liner plate fixing with mightiness belt. Large stretch of film is PET and PE composite material film, and small pieces film is PE film, outside the PET of large stretch of film faces, in the PE of large film faces, is welded on bag body 3 together with small pieces film. On pkt. flap 3, scald and have valve port 5, facilitate liquid input and output material.
