Abstract
The utility model provides a kind of lines vacuum bag, including the bag for being formed of being fitted by the side of film three, and the first burr is formed with the one side on the inside of the bag, and the first groove is formed between two first adjacent burrs；The second reverse burr is formed with the another side relative with the side, the second groove is formed between two second adjacent burrs.Lines vacuum bag described in the utility model, when vacuumizing, first burr and second burr interlock, and air efficiently discharges vacuum bag along the first groove and the second groove, the vacuum in the speed and bag of air discharge is substantially increased, vacuum pumping rate is fast.
Description
Technical field
The utility model is related to vacuum bag technique field, in particular it relates to a kind of lines vacuum bag.
Background technology
Vacuum bag is also referred to as decompression packaging, is sealed after the air in packing container is pumped into low vacuum, maintains to be in bag
Height decompression state, because residual air is few in bag, suppress the breeding of the microorganisms such as bacterium, it is to avoid materials oxidated, goes mouldy
And corruption, reach that fruit is fresh, the disease-free rotten purpose for occurring.For some soft articles, through vacuum packaging after, bag can be reduced
Dress volume, is readily transported and stores, and vacuum packing machine can be completed to bag vacuum, sealing, the overall process being vented.
The existing vacuum bag two sides for suction type vacuum machine is common plastics, and the inner surface of plastics is very smooth, one
As manufactured using flat sheet membrane, when extracting vacuum, smooth upper and lower diaphragm is easy to be close together, and causes some local air in bag
It is difficult to extract, remains in the gas in bag and also compare many.In order to overcome the deficiencies in the prior art, each vacuum bag producer is actively studied
Chinese utility model patent CN2900380Y discloses a kind of straight burr vacuum bag, is indulged on the side inwall of vacuum bag
To setting concavo-convex alternate striped, striped can allow the convex edge in striped to be close to the another side of bag in pumping, and gas is from groove
Discharge, so as to reduce the gas of residual in bag.However, the exhaust groove direction grabbed is single, it is unfavorable for exhaust.In order to improve
Exhaust effect, Chinese utility model patent CN202449341 discloses a kind of vacuum bag, including by two plastic sheetings combinations
Into bag, bag inner side is provided with air slot, and the air slot is the pressing mold groove of bag, the pressing mold groove be divided into pod line and
Translot line, pod line and translot line intersect vertically to form netted.When extracting the air in bag with outer pumping vacuum equipment, air exists
Pod line flows with translot grain toward sack direction, because pod line intersects vertically to form netted with translot line, so that air
Discharge be in netted flowing, substantially increase the vacuum in speed and the bag of air discharge.
Although utility model patent CN2900380Y improves the vacuum in the speed and bag of the air discharge of vacuum bag
Degree, but, effect is unsatisfactory, it is necessary to longer time is vacuumized, and plastic sheeting is short several several days or even several
In hour, air will be reentered in bag, lose the effect of reduced vacuum.
Utility model content
In order to overcome the deficiencies in the prior art, the utility model provides a kind of lines vacuum bag, when vacuumizing, can
Efficiently the gas in discharge bag, improves the vacuum in bag.
The technical solution of the utility model is as follows：
A kind of lines vacuum bag, including the bag for being formed of being fitted by the side of film three, form on the one side on the inside of the bag
There is the first burr, the first groove is formed between two first adjacent burrs；It is formed with the another side relative with the side anti-
To the second burr, form the second groove between two second adjacent burrs.
The width of first burr and second burr is 0.3-0.4mm.
The width of first groove and second groove is 1.0-1.5mm.
First burr and second burr and the angle on the base of vacuum bag are 20-80 °.
The beneficial effects of the utility model are：Lines vacuum bag described in the utility model, when vacuumizing, described first
Burr and second burr interlock, and air efficiently discharges vacuum bag along the first groove and the second groove, substantially increases sky
Vacuum in the speed and bag of gas discharge, vacuum pumping rate is fast.
Brief description of the drawings：
Fig. 1 is the structural representation of lines vacuum bag described in the utility model.
Specific embodiment
In order that utility model purpose of the present utility model, technical scheme and technique effect become more apparent, tie below
Specific embodiment is closed to be described further the utility model.It should be understood that specific embodiment described herein and correlation
Accompanying drawing, is only used for explaining the utility model, is not used to limit the utility model.
Referring to Fig. 1, a kind of lines vacuum bag, including fitted by the side of film three bag 1 for being formed, the side on the inside of the bag
The first burr 6 is formed with face 1, the first groove 7 is formed between two first adjacent burrs 6；The opposite side relative with the side
The second reverse burr 8 is formed with face 2, the second groove 9 is formed between two second adjacent burrs 8.
The width of first burr 6 and second burr 8 is 0.3-0.4mm.First groove 7 and described second
The width of groove 9 is 1.0-1.5mm.First burr and second burr and the angle on the base of vacuum bag are 20-
80°。
Above content is to combine specific preferred embodiment further detailed description of the utility model, it is impossible to
Assert that specific implementation of the present utility model is confined to these explanations.For the ordinary skill of the utility model art
For personnel, without departing from the concept of the premise utility, its framework form can be flexible and changeable, can be produced with subseries
Product.Some simple deduction or replace are simply made, the utility model should be all considered as belonging to true by the claims submitted to
Fixed scope of patent protection.
