The bag body 1 is provided with a bag surface layer 4 and a bag bottom layer 5, the bag surface layer 4 and the bag bottom layer 5 are combined with a closed end 2 to form a cavity for loading objects of the bag body 1, as shown in fig. 1 and 5, at least one side of the inner side surfaces of the bag surface layer 4 and the bag bottom layer 5 is provided with a plurality of rows and each row is provided with a plurality of flow-resisting bulges 401, the flow-resisting bulges 401 are uniformly distributed in the same row, gaps between the adjacent flow-resisting bulges 401 in the same row form a dike mouth 402, the dike mouth 402 is blocked by the flow-resisting bulges 401 positioned in the next row towards the direction of an open end 3, as shown in fig. 5, any dike mouth 402 is selected and is completely blocked by one flow-resisting bulge 401 in the adjacent row (namely the next row) towards the direction of the open end 3 shown in fig. 5, however, the gaps between the adjacent flow-resisting bulges 401 in the adjacent rows are communicated to form an air guide channel 403, and an air path 12, possible flow directions of the air, as shown in fig. 5, the air guide channel 403 communicates with the open end 3.

The following brief description is to briefly explain the principle of the utility model used for the evacuation package: as shown in fig. 2 to 4, the vacuum sealing machine 9 is a common device in the market at present, which can vacuumize the bag body 1 and thermally bond the side of the open end 3 of the bag body 1, and the vacuum sealing machine 9 includes two annular sealing rings 901, when in operation, one of the annular sealing rings 901 is located on the upper side of the bag body 1, and the other annular sealing ring 901 is located on the lower side of the bag body 1, because the annular sealing rings 901 are fixed on the upper and lower inner walls of the vacuum sealing machine 9, when they simultaneously press the portion of the bag body 1 on the side of the open end 3, a closed space is enclosed inside the two annular sealing rings 901, air is pumped from the air pumping port 903, air inside the bag body 1 is pumped from the open end 3, and the sealing device 902 is a pressure head for performing thermal compression bonding, because the vacuum sealing machine 9 is a common product in the market, and the structure and function thereof will not be described in. As can be seen from the above, the vacuum sealing machine 9 forms a row of suction negative pressures in the vertical arrow direction shown in fig. 5 to the open end 3, at this time, the portions of the bag surface layer 4 and the bag bottom layer 5 near the open end 3 are sucked by the negative pressures to stick together, as shown in fig. 5 by reference numeral 12, the air in the bag body 1 flows back to the open end 3 from the dam 402, some food in the bag body 1 may have a large oil ratio, or thick oil adheres to the vicinity of the open end 3 when food is loaded, as shown in fig. 5, the food oil 10 is sucked by the negative pressures to flow toward the open end 3, but because of the obstruction of the flow-obstructing protrusion 401, and the negative pressures are evenly distributed along the length direction of the open end 3, the food oil 10 will be split into two or approximately equal amounts of fluid after hitting the flow-obstructing protrusion 401, as a result, as shown in fig. 5, the food oil 10 is continuously dispersed, and the path becomes circuitous, and the friction force between the air and the flow-resisting protrusion 401 is much smaller than the friction force between the food oil 10 and the flow-resisting protrusion 401, so that the air-extracting process is completed during the process of the dispersion and circuitous of the food oil 10, the sealing device 902 is thermally pressed and bonded to the bag body 1, and the packaging is completed, so that the possibility that the food oil 10 or other fine impurities are extracted into the annular sealing ring 901 is very low.

Further, fig. 5 shows the first embodiment of the present invention, the length direction of the flow-blocking protrusion 401 is parallel to the row direction of the flow-blocking protrusion 401, fig. 8 shows the second embodiment of the present invention, the flow-blocking protrusion 401 is inclined to the row direction, as shown in the path of the food oil 10 in fig. 8, the blocking effect of the flow-blocking protrusion 401 is not good, so the first embodiment is preferred.

Further, as shown in fig. 6, the width (dimension L1) of the dykes 402 is set to be one fifth to one fourth of the length of the flow-obstructing protrusion 401, the gap (dimension L2) between adjacent rows of the flow-obstructing protrusion 401 is set to be one half to two thirds of the width of the flow-obstructing protrusion 401, the width of the flow-obstructing protrusion 401 is set to be about 1 mm, and the length is set to be about 3.5 mm, which arrangement is made to take both the obstructing effect and the speed of the air flow into consideration.

Further, as shown in fig. 6, both ends of the flow blocking protrusion 401 in the length direction are provided with sharp corners 4011, and when a part of the food oil 10 shown in fig. 6 flows to the inclined surface of the sharp corner 4011, it is guided and partially bounces to an adjacent sharp corner 4011, which further delays the flow of the food oil 10 to the open end 3. As shown in fig. 9, in the third embodiment of the present invention, the flow-blocking protrusion is set to be a fillet at both ends, and it can be seen from the arrow analysis of fig. 9 that the fillet can not play the effect of rebounding the food oil 10, so the first embodiment of the present invention is preferable.

Further, as shown in fig. 5, the length direction of the flow-obstructing protrusion 401 is parallel to the opening end 3, that is, the suction force generated by the negative pressure to the food oil 10 is perpendicular to the flow-obstructing protrusion 401, so that when the food oil 10 or the fine impurities collide with the flow-obstructing protrusion 401, the possibility of equally splitting the food oil 10 or the fine impurities into two paths of fluid is the highest, that is, the blocking and dispersing effects are good.

Further, as shown in fig. 1, the outer edge of the closed end 2 is provided with a tearing notch 6 for opening the choke type vacuum packaging bag, the tearing notch 6 is in a shape with a gradually decreasing width from outside to inside, such a shape is relatively sharp, when a hand tears the choke type vacuum packaging bag from this position, force can be concentrated at the tip of the tearing notch 6, the packaging bag can be torn with less force, and food can be taken out conveniently.

As shown in fig. 7, which is a schematic view of the prior art vacuum packaging bag when being evacuated, the close contact area 13 is the area which is contacted by the negative pressure, and the non-close contact area 14 is the area which is supported by the food oil 10 and the air, because the close contact area 13 has no air flow basically, the negative pressure of the non-close contact area 14 is much higher, and the food oil 10 is carried by the air and directly flows out from the open end, thereby polluting the vacuum sealing machine 9.

Meanwhile, in the three embodiments, the flow-blocking protrusions 401 may be separately provided on the inner side surfaces of the bag surface layer 4 or the bag bottom layer 5, or the flow-blocking protrusions 401 may be provided on both the inner side surfaces of the bag surface layer 4 and the bag bottom layer 5. Additionally, for the above embodiment, in the case that the flow-resisting protrusions 401 are provided on both the protrusions 4 on the inner side of the bag surface layer 4 and the inner side of the bag bottom layer 5, the following two vertical arrangements are possible: (A) the flow-resisting bulges 401 on the inner side surface of the bag surface layer 4 and the flow-resisting bulges 401 on the inner side surface of the bag bottom layer 5 are mutually and correspondingly pressed up and down, namely the flow-resisting bulges 401 on the inner side surface of the bag surface layer 4 and the flow-resisting bulges 401 on the inner side surface of the bag bottom layer 5 are arranged in an up-and-down overlapping manner, the arrangement form ensures that the air guide channel 5 formed between the flow-resisting bulges 401 has enough height, the sucked air has enough high flow transmission clearance, and the blockage of the air guide channel 403 by foreign matters can be avoided to the maximum; (B) the mutual dislocation set from top to bottom of the protruding 4 of bag surface course 4 medial surface and the choked flow of the 5 medial surface of bag bottom 401, the choked flow of the protruding 401 of the choked flow of the 4 medial surface of bag surface course and the choked flow of the 5 medial surface of bag bottom 401 set up to non-overlapping and arrange promptly, this mode of setting has realized that air guide 403 has sufficient quantity from on the other hand, realizes that the air in the bag body can be outwards sucked fast, realizes the effect of quick evacuation.
