Description

Valve port paper bag with interior finishing strips

Technical field

The utility model relates to a kind of valve port paper bag, particularly a kind of valve port paper bag with interior finishing strips.

Background technology

At present, the valve port paper bag is widely used in the packing of powder body material, and particularly the valve port paper bag is after can, and outward appearance is square-folded, is all extremely convenient and safety of pile or transportation.But along with powder body material grain size granular more and more, the valve port paper bag is because of the deficiency on the original structure causes leaking powder, problem such as make moist has displayed.

As shown in Figure 1, bag tube 1 is to open with two-layer or multiwall kraft, forms along bag tube 2 bonding paper edges, bonding position, is folded into the bag tube along bag tube top bending line 3 and bag tube bottom bending line 4 again.

Prepare to make the bag end, upward be converted into two hexagons shown in Figure 2 at the bottom of the lower valve port bag with two among Fig. 1, two big structures that constitute the valve port paper bag are that bag is gone up bottom structure 15 under bottom structure 14 and the bag, at bag upper base glue place 5 and bag glue place 13 cementings of going to the bottom, the also spreading glue at the first glue place 8 and the second glue place 9, bottom structure 14 is along the first doubling fold line 6 on the bag, 7 pairs of the second doubling fold lines are folding, bottom structure 15 is along the 3rd doubling fold line 10 under the bag, 11 pairs of the 4th doubling fold lines are folding, finish bag last bottom structure 14 and the bag bonding work of bottom structure 15 down, bottom structure 15 symmetries under bottom structure 14 and the bag on the bag.

As shown in Figure 3, material pours into from pan feeding valve port 16, and material falls into bag 12.When can be the bigger material of particle the time, the valve port paper bag does not have the problem on the function, still, when material was the smaller fine powder of particle, problem had just occurred.Among Fig. 2 first folds trace root A, the second folding trace root B, the 3rd folding trace root C, the 4th folding trace root D, the 5th folding trace root E, the 6th folding trace root F, the 7th folding trace root G, the 8th folding trace root H place has been coated with has put glue on the skin, but because paper is flexible, the paper of multilayer particularly, the elasticity of paper has synergistic effect, can not be at this position by bonding, the hole that a folding trace root is arranged all the time, this hole is with being communicated with in the bag, the micro mist material will two-way ejection from these spaces, cause material from leakage, cause the packing failure.

The utility model content

Technical problem to be solved in the utility model provides a kind of valve port paper bag with interior finishing strips, it realizes complete closed bag, imporosity, does not leak material, air tight, material can not make moist, do not have the foreign matter pollution risk.

For solveing the technical problem, the utility model provides a kind of valve port paper bag with interior finishing strips, valve port paper bag with interior finishing strips comprises a bag last bottom structure, bag is bottom structure down, the first doubling fold line, the second doubling fold line, the first glue place, the second glue place, the 3rd doubling fold line, the 4th doubling fold line, bottom structure and the bag symmetrical configuration of going to the bottom on the bag, the first doubling fold line, the second doubling fold line, first glue is in bag last bottom structure, the second glue place, the 3rd doubling fold line, the 4th doubling fold line is under bag in the bottom structure, it is characterized in that, valve port paper bag with interior finishing strips also comprises finishing strips in first, finishing strips in second, finishing strips glue district in first, finishing strips glue district in second, in first finishing strips glue district be positioned at first finishing strips around, in second finishing strips glue district be positioned at second finishing strips around, finishing strips is bonded in the first doubling fold line in first, the second doubling fold line, first glue everywhere, finishing strips is bonded in the second glue place in second, the 3rd doubling fold line, the 4th doubling fold line place.

Positive progressive effect of the present utility model is: the utility model has thoroughly solved the problem that the valve port paper bag all the time can't complete closed, realize complete closed bag, imporosity, do not leak material, air tight, material can not make moist, do not have the foreign matter pollution risk.

The specific embodiment

Lift a preferred embodiment below, and come the clearer the utility model that intactly illustrates in conjunction with the accompanying drawings.

As shown in Figure 4 and Figure 5, the valve port paper bag of finishing strips comprises a bag upper base glue place 5 in the utlity model has, the first doubling fold line 6, the second doubling fold line 7, the first glue place 8, the second glue place 9, the 3rd doubling fold line 10, the 4th doubling fold line 11, bag 12, the bag glue place 13 that goes to the bottom, bottom structure 14 on the bag, bag is bottom structure 15 down, pan feeding valve port 16, finishing strips 18 in the finishing strips 17 and second in first, finishing strips glue district 19 in first, finishing strips glue district 20 in second, the first shutoff district 21 and the second shutoff district 22, at bag upper base glue place 5 and bag glue place 13 cementings of going to the bottom, the also spreading glue at the first glue place 8 and the second glue place 9, bottom structure 14 is along the first doubling fold line 6 on the bag, 7 pairs of the second doubling fold lines are folding, bottom structure 15 is along the 3rd doubling fold line 10 under the bag, 11 pairs of the 4th doubling fold lines are folding, finish bag last bottom structure 14 and the bag bonding work of bottom structure 15 down, bottom structure 15 symmetries under bottom structure 14 and the bag on the bag.In first finishing strips glue district 19 be positioned at first finishing strips 17 around, in second finishing strips glue district 20 be positioned at second finishing strips 18 around, finishing strips 17 is bonded in the first doubling fold line 6, the second doubling fold line 7,8 places, the first glue place in first, and the second interior finishing strips 18 is bonded in the second glue place 9, the 3rd doubling fold line 10, the 4th doubling fold line 11 places.The first shutoff district 21 is arranged in bag last bottom structure 14, the second shutoff districts 22 and is arranged in a bag following bottom structure 15.

The valve port paper bag manufacturing process of finishing strips is as follows in the utlity model has: before the bonding bag end up and down, at the right part at the last bag end tubular valve port 23 is installed earlier, finishing strips glue district 20 spreading glue in the finishing strips glue district 19 and second in first afterwards, stick in the position in bag last bottom structure 14 and the following bottom structure 15 of bag, so in advance after at the bottom of the moulding also with the first folding trace root A of bag 12 internal communication, the second folding trace root B, the 3rd folding trace root C, the 4th folding trace root D, the 5th folding trace root E, the 6th folding trace root F, the 7th folding trace root G, the 8th folding trace root H shutoff is fallen, to reach the purpose of complete closed bag.

During use, open pan feeding valve port 16, material is filled in the bag 12, because the effect of interior finishing strips, at the first shutoff district 21 and the second shutoff district, the 22 thorough first folding trace root A that might be communicated with bag in-to-in hole district, the second folding trace root B, the 3rd folding trace root C, the 4th folding trace root D, the 5th folding trace root E, the 6th folding trace root F, the 7th folding trace root G, the hole of folding trace root thoroughly blocks among the 8th folding trace root H, perfection has realized the complete closed of bag, with the complete can of fine powder body material in bag 12.

Though more than described the specific embodiment of the present utility model, but those skilled in the art is to be understood that, these only are casehistorys, under the prerequisite that does not deviate from principle of the present utility model and essence, can make numerous variations or modification to these embodiments.Therefore, protection domain of the present utility model is limited by appended claims.
