Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
As shown in Figures 1 to 5, the utility model provides a kind of adjustable type PLA degradation freshness-retaining vegetable packaging bag, including
Packaging bag body 1,1 bottom of packaging bag body are also equipped with spring air cushion 2, and 1 side of packaging bag body is respectively arranged with four
The identical edge bag webs 3 of size, and be fixedly connected between adjacent edge bag webs 3 by elastic component 4, the elastic component 4 includes
It is connected to the fixation pressure zone 401 of 3 two sides of edge bag webs, is connected with bullet between the fixation pressure zone 401 between adjacent edge bag webs 3
Property soft band 402, soft 402 surface of band of elasticity forms several bent areas 404 by several folding line portions 403, each is curved
404 inner wall of folding area is provided with spring pad 405, passes through several horizontally disposed elastic rubbers between several bent areas 404
Item 406 is fixedly connected, and the wire 407 of cross-like is additionally provided with inside the soft band 402 of elasticity, and adjacent edge bag webs 3 it
Between be also connected with limit the soft item 6 of PVC.
The packaging bag in actual use, since four block edge bag webs 3 are fixed together by elastic component 4,
In actual use, using the elastic reaction of elastic component 4, in elastic limit, side can freely be changed according to the needs of packaging
The distance between edge bag webs 3 can pack the vegetables of different volumes respectively, meet people to change the volume size of packaging bag body
Daily shopping use demand.
When specifically used, two adjacent edge bag webs 3 are pulled out, so that elastic deformation occurs for elastic component 4, in pulling force
Under the action of, multiple bent areas 404 of the soft band 402 of elasticity are located remotely from each other, while the spring pad 405 inside bent area 404 is drawn
It stretches, so that elastic soft band 402 is stretched, so that the distance between adjacent edge bag webs 3 increases, to increase
The volume of entire packaging bag body 1, convenient for packing the vegetables of different volumes.
And in actual use, the elastic reaction that can also utilize elastic component 4, is put into packaging bag body 1 in vegetables
After portion, 4 entirety of elastic component is strutted, volume adjustment also may be implemented, it is easy to use.
Further, due to the wire 407 of the setting cross-like inside the soft band 402 of elasticity, elasticity can effectively be enhanced
Toughness and intensity inside soft band 402 are not susceptible to damage when stretching and being extruded, and in adjacent edge bag
The soft item 6 of the limit PVC connected between piece 3 prevents elastic component 4 to be excessively stretched and surpass for limiting to entire elastic component 4
Limit is crossed, is played a good protective effect.
The folding line portion 403 includes the arc-like sheet 408 being connected on two bent areas 404, two adjacent arcs
It is connected between piece 408 by elastomer 409, when the soft band 402 of elasticity of elastic component 4 is stretched, drawing force
It is shared by the spring pad 405 of multiple bent areas 404, while by between two arc-like sheets 408 inside folding line portion 403
Elastomer 409 carry out multi-buffer so that the drawing force of elastic component 4 is shared, reduce the soft band of elasticity of elastic component 4
402 drawing force plays a good protective effect to the soft band 402 of elasticity, effectively prevent the soft band 402 of elasticity because prolonged draw
It stretches and damages, extend whole service life.
1 inner wall of packaging bag body is provided with hydrophobic membrane 5, and the hydrophobic membrane 5 includes the inside and outside nano-silica set gradually
SiClx layer 501, PDMS film base 502 and nano fibrous membrane 503, and nano silicon dioxide layer 501, PDMS film base 502 and receive
It is combined together between rice tunica fibrosa 503 by stamp spinning liquid layer 504, and when vegetables are packaged in inside packaging bag body 1
It waits, by the hydrophobic protective effect of hydrophobic membrane 5, makees the moisture from vegetable surface is effectively reduced to the erosion of packaging bag body 1
With, while the hydrophobic effect of hydrophobic membrane 5, it also effectively prevent packaging bag body 1 to absorb water, guarantees vegetables in 1 interior packing of packaging bag body
When storage, moisture is not easily runed off.
And it is utilized by the hydrophobic membrane 5 that nano silicon dioxide layer 501, PDMS film base 502 and nano fibrous membrane 503 form
The double action of nano silica and nanofiber carries out hydrophobic protection, plays good hydrophobic effect, and stamp spinning solution
Pertinent relation between effectively enhancing 5 detail analysis of hydrophobic membrane of layer 504, enhances the using effect of hydrophobic membrane 5, extends it and use the longevity
Life.
1 outer wall of packaging bag body is additionally provided with ventilative network interface 201, and 1 surface of packaging bag body is hinged and is connected to covering gas-permeable nets
Mouthfuls 201 flip lid piece 202,202 inner wall of flip lid piece are provided with gas cell 203, and spring air cushion 2 by plastic tube 204 and
Gas cell 203 connects, and is placed due to vegetables and is deposited in 1 bottom of packaging bag body, it is easy to the vegetables of bottom be caused to lack fresh sky
Gas and there is anaerobic respiration, consume the nutriment of vegetables, influence the preservation and use of vegetables, at this time by spring air cushion 2
Effect carries out ventilative management, and when normal, in the state expanded inside spring air cushion 2, external flip lid piece 202 is in gravity
Effect is lower to be freely fitted in ventilative 201 surface of network interface, and ventilative network interface 201 is closed, and is stored in packaging bag body 1 in vegetables
After inside, vegetables generate squeezing action to spring air cushion 2, and spring air cushion 2 is caused to deform, and the gas inside spring air cushion 2 is logical
It crosses plastic tube 204 to be injected into inside the flip lid piece 202 at edge, after flip lid piece 202 is inflated, due to its surface irregularity, make
Its space that connection is formed between ventilative network interface 201, convenient for ventilative, convenient for the preservation of vegetables, and in vegetables from packaging bag
After taking out inside body 1, since spring air cushion 2 loses squeezing action, under internal spring effect, spring air cushion 2 restores
To original position, so that the gas loss of flip lid piece 202 falls back to original position to renovate the reinstatement of piece 202 again
It sets, ventilative network interface 201 is covered, packaging bag body 1 is closed.
It should be noted that flip lid piece 202 in the present embodiment can be using the magnetic material with adsorption capacity, just
It is attached together in edge bag webs 3.
It is obvious to a person skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and
And without departing substantially from the spirit or essential attributes of the utility model, it can realize that this is practical new in other specific forms
Type.Therefore, in all respects, the present embodiments are to be considered as illustrative and not restrictive, this is practical new
The range of type is indicated by the appended claims rather than the foregoing description, it is intended that containing for the equivalent requirements of the claims will be fallen in
All changes in justice and range are embraced therein.It should not treat any reference in the claims as limiting
Related claim.
