Description
Technical field
The utility model is related to pesticides packaging technical field more particularly to a kind of safety-type packing bag for agricultural chemical structures.
Background technology
Traditional pesticide is that large glass is bottled, and vial stores pesticide, and there are inconveniences：First, transport is inconvenient, glass
Glass bottle is fragile article, is easily broken in transit；Second, vial weight is big, and transportation cost is very high；Third, one bottle of pesticide
Long period of time usually can be used, after opening bottle when using for the first time, pesticide is just contacted with air, when using later
Drug effect can be reduced slowly.In order to mitigate hauled weight, prevent vial in transportational process broken, some pesticides use modified plastics
Packed in flexible pouchy, but this brings and is easily broken, is readily volatilized, being easy the new problems such as leakage again.
Utility model content
There are the above problems in order to solve pesticide bottle in the prior art for the utility model, provide a kind of safety-type pesticide
Package construction, this kind of packing bag for agricultural chemical is light-weight, non-breakable, and pesticide good seal performance is not easy leakage failure.
To achieve the goals above, the utility model adopts the following technical solution：
A kind of safety-type packing bag for agricultural chemical structure, including the symmetrical substrate of two panels, the substrate wrap successively from inside to outside
Include PE layers, PVC bases, CPP printing layers, the substrate is equipped with cavity, the PE layer hot pressing connects on two panels substrate, cavity
Open end is fastened and connected to form liquid storage cylinder, and the liquid storage cylinder includes main cavity, bottleneck chamber, goes out sap cavity, the front end of the substrate
Torsion auricle is extended to form, the both sides for being located at sap cavity on the torsion auricle are equipped with V-shaped groove, the lateral surface of the cavity
Both sides are equipped with deformation groove.Pesticide is encapsulated in liquid storage cylinder, and PE layers of corrosion resistance and good, PVC bases barrier property is good, substrate
Between by PE layers of hot pressing connects, good seal performance, in transportational process when liquid storage cylinder is pressurized, deformation cavity can coordinate deformation,
And deformation chamber also adapts to expand with heat and contract with cold, and liquid storage cylinder is prevented to be squeezed and broken or burst；When needing using pesticide, torsion auricle is pinched
Auricle rotation 180 degree will be reversed, is disconnected at V-shaped groove, reverses auricle and substrate separation, connected with the external world so that going out at sap cavity
It is logical, and then smoothly pesticide is squeezed out and is used.
Preferably, be equipped with elastic support ring in the main cavity, the upper and lower ends of the elastic support ring respectively at
Support is avoided contact in cavity, the left and right ends of the elastic support ring are respectively equipped with elastic subring, the elasticity auxiliary
The inner end of ring is connect with elastic support ring, and the outer end of the elasticity subring extends to form locating plate, and the locating plate passes through
Substrate clamping position.Elastic support ring, elastic subring play a supporting role to liquid storage cylinder, improve the compressive property of liquid storage cylinder；
When squeezing out pesticide, after squeezing liquid storage cylinder, liquid storage cylinder can reset under the action of elastic support ring, elastic subring, to outer
In boundary's air sucking liquid storage cylinder, pesticide is squeezed again, can to greatest extent be squeezed out pesticide by way of this reciprocating extrusion,
Reduce residual of the pesticide in liquid storage cylinder.
Preferably, the both sides of the upper and lower ends of the elastic support ring are equipped with support ear.Support ear is to resilient support
Ring plays positioning action, the axis torsion of elastic support ring when preventing from squeezing liquid storage cylinder.
Therefore, the utility model barrier property is good, pesticide storage safety, not cracky in transportational process；And pesticide squeezes
Can be maximally reduced when going out pesticide drug storage intracavitary residual.
