Abstract

The utility model provides a proclaim oneself formula internal valve pocket, will solve the poor and sealed technical problem with high costs of improvement of current internal valve pocket sealing performance, belongs to packaged item technical field. Its characterized in that: the filling passageway is that the valve port is shape and the structure of circle fiber container after flattening, and first thread gluing area has been put to the medial surface it on, and lower medial surface relative position has put second thread gluing area, arranges the barrier paper between first thread gluing area and the second thread gluing area in, tears the fifty percent discount of trace line V -arrangement along the centre, most advanced importer towards the filling passageway to, barrier paper tail end tip and filling mouth tip is connected. The beneficial effects are that: when the filling is accomplished, in the bag under the extrusion of material, because the centre has not had the barrier paper, the hair side and the automatic pasted closure filling passageway of hook face in thread gluing area, simple structure, with low costs, production efficiency is high.

Description

Valve bag in self-sealing

Technical field

The utility model relates to a kind of valve bag, and interior valve bag that be specifically related to a kind of good airproof performance, that be with Self-enclosing, belongs to package packing supplies technical field.

Background technology

Valve bag, adopts special filling apparatus, from the valve port charging being placed in side, packaging bag end, material-filling completely after packaging bag be cuboid, heap bag is neatly, convenient transportation, firmly attractive in appearance, is the packaging bag pattern of current international popular.Described valve port and filling passage, be exactly the round paper tube flattened a section, be bonded in sack tip inside face, time filling, cylindrical filling head can insert and hold round the filling passage be made up of round paper tube.Two kinds of valve port type bags---interior valve bag and outer valve bag is used in a large number at dry powder building material industry (as glue for tile, Joint sealing material, special cement), interior valve bag is used for automatic loading production line, after threading powder, the mode of up pushing up by powder seals filling passage.Outer valve bag also needs the manual folding filling exit be exposed after installing powder, fill in dead slot below and realize sealing, outer valve bag leak tightness is better than interior valve bag, but efficiency hand-manipulated is low.The side of filling passage is pressed to opposite side by interior valve bag after fill material, thus makes this filling channel enclosed.According to this design, packing material likely has a little outside leakage to cause content to lose, and in using, valve port has a little leakage powder, and leak tightness is slightly poor.Those skilled in the art, for overcoming this defect, attempt.As scribbled hot melt adhesive inside valve port, filling rear use hot air or ultrasonic equipment are by valve closure, but this enclosure method cost is higher.Another kind method is that a sealing paper is pasted in the valve port outer end of bag after filling, not only unsightly cost but also high.

Summary of the invention

The purpose of this utility model is: provide that a kind of structure is simple, easy to use, valve bag in the self-sealing of good seal performance, low cost of manufacture, solve existing interior valve bag filling after can not automatic sealing poor sealing performance, and improve the high technical matters of sealing cost.

For solving the problem, the technical solution adopted in the utility model is: valve bag in a kind of self-sealing, comprise bag main body and the filling passage being placed in described bag body end, it is characterized in that: described filling channel end filling exit is flat structure, in described filling exit, upper side is equipped with the first sticking belt, downside relative position is equipped with the second sticking belt, barrier paper is equipped with between described first sticking belt and described second sticking belt, described barrier paper is along the doubling of middle tear mark line V-arrangement, the most advanced and sophisticated importer towards described filling passage to, described barrier paper tail end is connected with described filling channel end.

Described first sticking belt is fastener band matte surface, and described second sticking belt is Hook of thread gluing strap, or described first sticking belt is Hook of thread gluing strap, and described second sticking belt is fastener band matte surface, mutually matches setting.

The beneficial effects of the utility model are: 1. when after filling completing, in bag material extruding under, the hair side of sticking belt and hook side automatic bonding, by filling channel enclosed, eliminate filling rear because can not causing and leak material and the waste of material that causes and problem of environmental pollution by automatic sealing; 2. adopt sticking belt sealing, structure is simple, and cost is low, and efficiency is high, and easily realizes; 3. can substitute outer valve bag at low cost, enhance productivity.

Detailed description of the invention

Fig. 1, Fig. 2 are the filling front and filling rear filling channel architecture schematic diagram of valve bag in self-sealing respectively.Fig. 3 is filling passage deployed configuration schematic diagram, and Fig. 4 is that the A of Fig. 3 is to structural representation.As shown in Figure 1 to 4, valve bag in a kind of self-sealing, comprise bag main body and the filling passage being placed in described bag body end, it is characterized in that: described filling channel end filling exit is flat structure, in described filling exit, upper side is equipped with the first sticking belt 2, downside relative position is equipped with the second sticking belt 4, barrier paper 3 is equipped with between described first sticking belt 2 and described second sticking belt 4, described barrier paper 3 is along the doubling of middle tear mark line 5V shape, the most advanced and sophisticated importer towards described filling passage to, described barrier paper 3 tail end is connected with described filling channel end.

Described first sticking belt 2 is fastener band matte surface, and described second sticking belt 4 is Hook of thread gluing strap, or described first sticking belt 2 is Hook of thread gluing strap, and described second sticking belt 4 is fastener band matte surface, mutually matches setting.

Before use, the filling channel architecture schematic diagram of interior valve bag as shown in Figure 1, filling passage is positioned at bag inside, owing to being equipped with barrier paper 3 between described first sticking belt 2 and described second sticking belt 4, so be positioned at the sticking belt (hair side 2) of filling channel end and sticking belt (hook side 4) cannot bond.

During use, staff or manipulator pinch the filling access sites both sides of bag, and make filling passage open the filling head of rear insertion, barrier paper 3 first ejects by filling head from right to left, after the tear mark line 5 bursting barrier paper 3 then in the middle of barrier paper 3, carry out filling.Filling complete after, filling head detaches sack, the barrier paper 3 being now broken into two panels is stayed outside filling passage, under the extruding of described first sticking belt 2 (hair side) and described second sticking belt 4 (hook side) material in bag, is automatically bonded together filling channel enclosed.(as shown in Figure 2).

Fig. 3 is Fig. 1 filling passage medial surface 1 deployed configuration schematic diagram after horizontal axis cutting, and Fig. 4 is the A direction view of Fig. 3.Can be clear that from Fig. 3 and Fig. 4, described first sticking belt 2 and described second sticking belt 4 can by gum and filling passage medial surface 1, barrier paper 3 is bonding is connected, be symmetrical arranged, centered by tear mark line 5 in the middle of barrier paper 3, M shape folds, and last filling passage medial surface about 1 both sides are connected, and gum is bonding with filling vias inner walls is again connected.
