Abstract

The utility model discloses a closed inclined valve port woven bag, which comprises a side-sealed inner bag and an outer bag, wherein the inner bag is made of plastic film; the outer bag is woven by warp and weft and formed by sewing a rectangular front bag surface and a rear bag surface; the outer wall of the inner bag is bonded with the inner wall of the outer bag; sealing films are correspondingly bonded and coated on the surface of the inner bag and the sealing part; the inner bag is provided with a valve port which extends outwards out of the outer bag; and a longitudinal center line of the valve port is inclined to two edges of the surface of the outer bag; by strengthening the closing on the sealing parts of the sealing films, the sealing effect of the bag body can be ensured; and when in use, materials enter the inner bag from the valve port and then the valve port is folded back and sealed. The utility model has simple structure and convenient use.

Description

The oblique valve port woven bag of hermetic type

Technical field

The utility model relates to a kind of woven bag, the oblique 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 oblique valve port woven bag of a kind of hermetic type, and good seal performance is simple in structure, easy to use.

The oblique valve port woven bag of hermetic type of the present utility model, comprise banding formula inner bag of making by plastic sheeting and the outer bag that is made into by warp and parallel, outer bag is sewed up by rectangular anterior bag surface and back pkt. face and is formed, the inner bag outer wall is bonding with outer bag inwall, 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 the valve port longitudinal centerline favours two limits of outer bag bag face.

Further, described inner bag is monolateral envelope, and described valve port passes between outer bag anterior bag surface and back pkt. face.

The beneficial effects of the utility model: the oblique valve port woven bag of hermetic type of the present utility model, comprise banding formula inner bag of making by plastic sheeting and the outer bag that is made into by warp and parallel, outer bag is sewed up by rectangular anterior bag surface and back pkt. face and is formed, the inner bag outer wall is bonding with outer bag inwall, 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 the valve port longitudinal centerline favours two limits of outer bag bag face; Strengthen the fastness at edge sealing position by suture, by diaphragm seal suture position pinprick is carried out airtightly, ensure the bag sealing effectiveness, during use, material enters inner bag from valve port, and then the valve port sealing of turning back is got final product, and is 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 oblique valve port woven bag of the hermetic type of present embodiment comprises inner bag of being made by plastic sheeting 2 and the outer bag 1 that is made into by warp and parallel, outer bag is sewed up by rectangular anterior bag surface 11 and back pkt. face 12 and is formed, the inner bag outer wall is bonding with outer bag inwall, inner bag edge sealing position is sewed with the suture (not shown), the corresponding diaphragm seal 3 that covered with the suture position on the inner bag outer wall, inner bag is provided with valve port 4, valve port stretches out and passes outer bag, the valve port longitudinal centerline favours the seamed edge 5 and the seamed edge 6 of outer bag bag face, optimal way is: the valve port longitudinal centerline equates with angle between seamed edge 5 and the seamed edge 6, packing of product back pkt. shape is more regular, aesthetics is better, during use, material enters inner bag from valve port, and then the valve port sealing of turning back get final product, and suture prevents that inner bag edge sealing position from ftractureing, 3 pairs of suture positions of diaphragm seal pinprick carries out airtight, ensures the bag sealing effectiveness.

As the further improvement of the foregoing description, described inner bag is monolateral envelope, and the banding position is few, and resistance to pressure is better, and described valve port passes between outer bag anterior bag surface and back pkt. face, and it is easier to make.

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.
