Description

Double rib valve bags

Technical field

The utility model relates to a kind of valve bags, specifically, being to be related to a kind of double rib valve bags.

Background technique

The self-sealed article at valve bag sack generally only has one at present, when seal sack, recessed strip of paper used for sealing and convex strip of paper used for sealing it Between be easy to disengage, sealing reliability is poor；Furthermore the recess of recessed strip of paper used for sealing is very narrow, and lacks guide structure, cause to be difficult to convex strip of paper used for sealing It is caught in the indent of recessed strip of paper used for sealing, the sealing difficulty of valve bag is high.

Utility model content

The purpose of this utility model is that solve the above-mentioned problems and provides a kind of double rib valve bags.

The utility model achieves the above object through the following technical schemes:

The sack inside of a kind of double rib valve bags, including bag body, the bag body is connected with self-sealed article, for sealing bag Mouthful, the self-sealed article includes mutually matched recessed strip of paper used for sealing and convex strip of paper used for sealing；

The recess two sides of the recessed strip of paper used for sealing are tiltedly installed with contraposition guide part, form one between the contraposition guide part of two sides A angle opened to the direction far from the recessed strip of paper used for sealing, the angle is for guiding the convex strip of paper used for sealing to be caught in the recessed strip of paper used for sealing；

The self-sealed article has two, respectively the first self-sealed article and the second self-sealed article, the recessed strip of paper used for sealing of first self-sealed article The wherein side in sack is arranged at the convex strip of paper used for sealing of second self-sealed article, the convex strip of paper used for sealing of first self-sealed article and described The recessed strip of paper used for sealing of second self-sealed article is arranged at the other side in sack.

Preferably, there are two inclined-plane, the contrapositions with the recessed strip of paper used for sealing two sides respectively of two inclined-planes for the convex strip of paper used for sealing setting Guide part corresponds, and two inclined-planes with the contraposition guide part of two sides for being bonded respectively.

Preferably, the contraposition guide part of the inclined-plane of the convex strip of paper used for sealing and the recessed strip of paper used for sealing is provided with ratchet, and it The tooth socket of ratchet that fits together it is contrary.

Preferably, the angle between the contraposition guide part of the recessed strip of paper used for sealing two sides is 90 °.

Compared with prior art, the utility model has the following beneficial effects:

Self-sealed article is added to two by one, and the recessed strip of paper used for sealing of two self-sealed articles and the convex strip of paper used for sealing of two self-sealed articles exist It is greatly improved not in the same side to sack sealing reliability at sack；Designing on recessed strip of paper used for sealing has for guiding convex envelope The contraposition guide part that item is caught in, more convenient operation can easily seal the sack of valve bag.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of double rib valve bags described in the utility model；

Fig. 2 is the schematic cross-sectional view of A-A in Fig. 1；

Fig. 3 is the partial enlarged view in Fig. 2 at B；

In above-mentioned attached drawing, the corresponding component names of appended drawing reference are as follows:

1- bag body, the first self-sealed article of 2-, the second self-sealed article of 3-, the convex strip of paper used for sealing of 4-, the recessed strip of paper used for sealing of 5-, 6- align guide part, 7- spine Tooth.

Specific embodiment

The utility model is described in further detail with reference to the accompanying drawing:

In conjunction with shown in Fig. 1, Fig. 2 and Fig. 3, the utility model includes bag body 1, is connected with self-sealed article on the inside of the sack of bag body 1, For sealing sack, self-sealed article includes mutually matched recessed strip of paper used for sealing 5 and convex strip of paper used for sealing 4；

The recess two sides of recessed strip of paper used for sealing 5 are tiltedly installed with contraposition guide part 6, form one between the contraposition guide part 6 of two sides A angle opened to the direction far from recessed strip of paper used for sealing 5, the angle is for guiding convex strip of paper used for sealing 4 to be caught in recessed strip of paper used for sealing 5；

Self-sealed article has two, respectively the first self-sealed article 2 and the second self-sealed article 3, the recessed strip of paper used for sealing 5 of the first self-sealed article 2 and The convex strip of paper used for sealing 4 of two self-sealed articles 3 is arranged at the wherein side in sack, the convex strip of paper used for sealing 4 of the first self-sealed article 2 and the second self-sealed article 3 Recessed strip of paper used for sealing 5 be arranged at the other side in sack.

The working principle of the utility model is as follows:

Compared with prior art, by the way that self-sealed article is designed as two, and their recessed strip of paper used for sealing 5 and convex strip of paper used for sealing 4 are same Side belongs to staggered designs, can greatly improve the sealing performance to sack, good reliability, between recessed strip of paper used for sealing 5 and convex strip of paper used for sealing 4 not Easily unclamp；

After self-sealed article is designed as two, the snap-action difficulty of corresponding recessed strip of paper used for sealing 5 and convex strip of paper used for sealing 4 is increased, and The design of contraposition guide part 6 on recessed strip of paper used for sealing 5, compensates for the defect, convex when corresponding convex strip of paper used for sealing 4 to be caught in recessed strip of paper used for sealing 5 The high-end relatively narrow part of strip of paper used for sealing 4 can easily align in the angle being caught between two sides contraposition guide part 6 very much, by folder It is squeezed on the inside of angle, high-end can squeeze of convex strip of paper used for sealing 4 slides in the groove of recessed strip of paper used for sealing 5, to smoothly complete contraposition clamping.

In the present embodiment, there are two inclined-plane, contraposition of two inclined-planes respectively with recessed 5 two sides of strip of paper used for sealing is led for the convex setting of strip of paper used for sealing 4 Corresponded to portion 6, two inclined-planes for be bonded respectively with the contraposition guide part 6 of two sides, the design can be improved recessed strip of paper used for sealing 5 and Convex strip of paper used for sealing 4 is clamped leakproofness, that is, improves the leakproofness to sack.

In the present embodiment, the inclined-plane of convex strip of paper used for sealing 4 and the contraposition guide part 6 of recessed strip of paper used for sealing 5 are provided with ratchet 7, and it The tooth socket of ratchet 7 that fits together it is contrary so that can engage between them, improve leakproofness and reliability.

In the present embodiment, the angle between the contraposition guide part 6 of recessed 5 two sides of strip of paper used for sealing is 90 °, we pass through the angle Be respectively prepared 60 °, 70 °, 80 °, 90 °, 100 ° angularly, the angle of 90 ° of discovery is not only more beautiful, and easy to accomplish convex Contraposition between strip of paper used for sealing 4 and recessed strip of paper used for sealing 5.

According to above embodiment, the utility model can be realized well.It is worth noting that being set based on above structure Under the premise of meter, to solve same technical problem, even if made on the utility model it is some without substantive change or Polishing, the essence of used technical solution is still as the utility model, therefore it should also be as the protection in the utility model In range.
