Abstract

The utility model discloses a sealed straight woven valve bag, which comprises an edge sealed inner bag and a square outer bag. A bag face of the outer bag is woven by wefts and warps, the inner bag is made of plastic films, a seal edge of the inner bag is sewn with sewing threads, seal films are adhered onto the outer wall, corresponding to the sewn portion, of the inner bag, a valve opening is arranged inside the inner bag and extends out of the outer bag, and a longitudinal center line of the valve opening is perpendicular to an edge of the outer bag. The sewn threads are used to prevent edge seal portions from cracking, and the seal films are used for reinforce sealing of the thread sewn portions, thereby guaranteeing sealing effect of a bag body. When in use, materials are filled into the inner bag from the valve opening, then the valve opening is folded back and sealed, and thereby the sealed straight woven valve bag is simple in structure and convenient in use.

Description

The straight valve port woven bag of hermetic type

Technical field

The utility model relates to a kind of woven bag, the straight valve port woven bag of particularly a kind of hermetic type.

Background technology

Woven bag is mainly used in the splendid attire and the packaging of various article, and is of many uses in industrial aspect.As packed and transported of food, vegetables, Geotechnical Engineering, daily living article etc.For easy absorption such as carbon black, titanium dioxide, powder of lacquer putty for use on, easy to leak product, packaging bag requires good airproof performance, and antiseep is strong in the transportation.In the prior art, be used for the easily packaging bag of adsorption production packing such as carbon black, its leak tightness is relatively poor, and after being squeezed or colliding, dust granules such as carbon black easily ooze out from the bag seam, make bearer's clothing dirty, bring pollution to environment, damage to human body.

The utility model content

In view of this, the purpose of this utility model provides the straight valve port woven bag of a kind of hermetic type, and good seal performance is simple in structure, easy to use.

The straight valve port woven bag of hermetic type of the present utility model, comprise banding formula inner bag and square outer bag, outer bag bag face is formed by warp and parallel braiding, inner bag is made by plastic sheeting, inner bag edge sealing position is sewed with suture, the corresponding diaphragm seal that covered of inner bag outer wall with the suture position, and inner bag is provided with valve port, valve port stretches out and passes outer bag, and face of valve port longitudinal centerline and outer bag is parallel and vertical with a limit of this face.

Further, described inner bag is monolateral envelope formula bag, and outer bag is sewed up by anterior bag surface and back pkt. face and formed or formed in the face of crease closes by the oblong bag; Inner bag is corresponding with outer bag shape, and valve port passes along outer bag suture site.

The beneficial effects of the utility model: the straight valve port woven bag of hermetic type of the present utility model, comprise banding formula inner bag and square outer bag, outer bag bag face is formed by warp and parallel braiding, inner bag is made by plastic sheeting, inner bag edge sealing position is sewed with suture, the corresponding diaphragm seal that covered of inner bag outer wall with the suture position, and inner bag is provided with valve port, valve port stretches out and passes outer bag, and face of valve port longitudinal centerline and outer bag is parallel and vertical with a limit of this face; Prevent banding position cracking by suture, by diaphragm seal the suture position is strengthened airtightly that ensured the sealing effectiveness of bag, during use, material enters inner bag from valve port, and then the valve port sealing of turning back is got final product, simple in structure, easy to use.

Description of drawings

Below in conjunction with the drawings and specific embodiments the utility model is further described.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 be Fig. 1 along A-A to cutaway view.

The specific embodiment

Fig. 1 is a structural representation of the present utility model; Fig. 2 be Fig. 1 along A-A to cutaway view.

As shown in the figure:

The straight valve port woven bag of the hermetic type of present embodiment comprises square outer bag 1 and banding formula inner bag 2, and outer bag bag face is formed by warp and parallel braiding; Outer bag can be a cube structure, also can sew up the structure that forms by anterior bag surface and back pkt. face, can also be to close the structure that forms by a bag in the face of crease; Inner bag is made by plastic sheeting, inner bag edge sealing position is sewed with the suture (not shown), the corresponding diaphragm seal 4 that covered of inner bag outer wall with the suture position, diaphragm seal is that plastic sheeting is (as polyethylene foil, polypropylene film) strip of making, inner bag is provided with valve port 3, valve port stretches out and passes outer bag, during use, material enters inner bag from valve port, and then with valve port turn back the sealing get final product, simple in structure, easy to use, valve port longitudinal centerline and face of outer bag are parallel and vertical with a limit of this face, make material package after, the bag shape is more regular, prevent edge sealing position cracking by suture, by diaphragm seal the pinprick at suture position is carried out airtightly, further ensure the bag sealing effectiveness.

As the further improvement of the foregoing description, inner bag is a single-side sealed structure, and resistance to pressure is better, and outer bag is sewed up by oblong anterior bag surface 11 and back pkt. face 12 and formed, and makes simplyr, and certainly, outer bag also can be formed in the face of crease closes by the oblong bag, and it is same easy to make; Interior bag shape corresponding with outer bag shape (both inner bag bag face was approximate parallel with outer bag bag face), resistance to pressure is better, the place that valve port closes the position along the long side seam of outer bag passes, the transverse width of valve port is not more than 1/2 of the long limit of outer bag, be convenient to material package, certainly, a place of outer bag minor face suture site, valve port edge passes equally and can realize the purpose of this utility model.

Explanation is at last, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
