In Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5 a, Fig. 5 b, the base material 5 of the drenched wet film 4 of sense is made up of cellulosic material, and be paper pulp, staple fibre or paper pulp and staple fibre mixed to copy in thing (carry out copy paper after being mixed by raw material and obtain material) any number of.And regenerated cellulose 6 is held on the cellulosic material of base material 5.In addition, base material open space 5a is as the opening portion between the cellulosic fiber of base material 5 and fiber.To cover the form of this base material open space 5a to keep regenerated cellulose 6.
In addition, non-woven fabrics 7 has the shear strength of wet film semi-finals more drenched than sense and arranges with the drench form of wet film 4 of stacked sense.In this case, the drenched wet film 4 of sense carries out stacked with the state clamped by 2 pieces of non-woven fabrics 7.In addition, the drenched wet device 8 of sense is formed with the form of the surrounding fixing the non-woven fabrics 7 feeling drenched wet film 4 and be laminated in the drenched wet film 4 of sense with framework 9.In addition, a part for fruit and vegetable box main body 2 is provided with opening portion, and to arrange the drenched wet device 8 of sense by the form of framework 9 its opening portion airtight.In addition, fruit and vegetable box main body 2 is provided with the space can preserving fruits and vegetables etc.
In addition, fruit and vegetable box main body 2 configures fruit and vegetable box lid 3, and be provided with opening portion in a part for fruit and vegetable box lid 3, also can be configured with the form of the wet device 8 that drenches relative to the next airtight sense in its opening portion.
First, the effect for the regenerated cellulose forming the drenched wet film 4 of sense is described.
Usual so-called cellulose is divided into naturally occurring cellulose and the large class of regenerated cellulose two.
First, cellulose is the carbohydrate (in fig .9 with the polysaccharide of chemical formulation) of the crystal structure comprised in natural plant cell wall, and reduction end towards on to adopt in crystallization be identical parallel chain structure.This parallel chain structure exists as trickle fiber, and is called as microfibre (microfibril) (the set unit of filamentary fibers element molecule).The cellulose of this microfibre state produces hydrogen bond and becomes firmly hydrogen bond aggregate (crystal region) when long macromolecule is fitly gathered between cellulosic molecule.Therefore, become the state that moisture between molecule can not enter (being difficult to enter), thus, no matter because humidity can continue to obtain identical crystal structure, so moisture no matter high humility or low humidity is all difficult to pass through.
But forming the drench regenerated cellulose 6 of wet film of sense of the present invention is as the biochemical again cellulose of raw material and be the carbohydrate (polysaccharide) represented by Fig. 9 using viscose fiber.Therefore, be that directly to apply flexibly the situation of natural material relative with cellulose, regenerated cellulose is by after cellulose naoh treatment, add carbon disulfide and obtain viscose fiber (sodium cellulose xanthate sodiumcellulosexanthate), acid treatment carried out to this viscose fiber thus returns to the regenerated cellulose of cellulose state again.Therefore, regenerated cellulose collapses as the crystal structure of cellulose character, also exist in a large number the non-reducing end of adjacent strand towards different antiparallel chains structure, i.e. noncrystalline structure.
Noncrystalline characteristic of this regenerated cellulose is not Hydrogenbond or part Hydrogenbond because of cellulosic molecule, so the moisture become in the dry state in air is difficult to enter into the state between cellulosic molecule when low humidity.In addition, become moisture when high humility and in aerial washy situation and easily enter into state between cellulosic molecule.Its result becomes swelling state, and the moisture (moisture) in air can move with the form of escaping, and the mobile quantitative change of moisture is many.By such characteristic, regenerated cellulose has along with humidity uprises and by the humidity of regenerated cellulose and the many character of moisture-inhibiting quantitative change, i.e. the feature of so-called hygroreception.
By the characteristic of the above such regenerated cellulose, the drenched wet film 4 of sense has along with humidity uprises and the many characteristic of moisture-inhibiting quantitative change.
The drenched wet film 4 of sense is by being set to 0.3 ~ 1.0g/cm by the density of base material 5
3, and relative to the area of described base material 5, the amount of regenerated cellulose 6 is set to 0.3 ~ 3.0g/m further
2, thus the rate of change of moisture-inhibiting ability in its high humidity regions (humidity is 90 ~ 95%Rh region) can be about 5 times of the rate of change of moisture-inhibiting ability in low humidity region (humidity is 10 ~ 50%Rh region).
Further, sense of the present invention drenches, the regenerated cellulose of wet film 4 is coating or the dippings by carrying out the viscose fiber of 20 ~ 50% to base material 5, then carry out acid treatment and cured fiber element and remain on base material 5 formed.If when viscose fiber concentration is less than 20%, as the fiber of base material 5 and the gap of fiber, the amount of the regenerated cellulose of base material open space 5a is because become and be difficult to form cellulose membrane less.Have again, when viscose fiber concentration is more than 50%, because the high so viscose fiber of viscosity can not enter in the base material open space 5a as the fiber of base material 5 and the gap of fiber equably, thus have the situation that is difficult to form cellulose membrane and have the situation producing spot.
Its result is, when being stored in the fruits and vegetables in fruit and vegetable box 1 and being a small amount of preservation or after just taking out a part of fruits and vegetables etc., in humidity in fruit and vegetable box 1 inside occurs to reduce, moisture owing to feeling the effect of drenched film 4 and the amount that discharges from fruit and vegetable box because be trace, so be substantially closed in fruit and vegetable box.In addition, preserve when being stored in the fruits and vegetables amount in fruit and vegetable box 1 and being large or for a long time, when the inner space of fruit and vegetable box 1 becomes high humility state, if the drenched wet film 4 of sense is the state of trace from the amount of moisture that fruit and vegetable box discharges, moisture then can be made to condense, the fruits and vegetables generation web rot that must preserve will be made by occurred condensation, but humidity transit dose can be made to increase by the effect of the drenched wet film 4 of sense, can not condense in fruit and vegetable box 1, and fruits and vegetables can be remained on can not the fresh state of web rot.
Further, as the means making viscose fiber soak into for base material 5, there is the method for being carried out by viscose fiber applying or flooding.Coating refers to surface viscose fiber being coated on base material 5, and dipping refers to and is immersed in viscose fiber by base material.This coating method is because only make regenerated cellulose be held in the surface of base material 5, so preferably viscose fiber can be impregnated into the method for the dipping of base material 5 inside by employing.
Further, to make viscose fiber be impregnated into for the purpose of base material 5 inside, after preferably viscose fiber being carried out applying or flooding, with mechanical roller pressuring machine from applying pressure up and down with the state making viscose fiber be in impregnation.
Have again, making after viscose fiber is impregnated in base material 5, as means regenerated cellulose 6 being held in base material 5, carry out acid treatment with sulfuric acid solution and to synthesize macromolecular fibre shape, viscose fiber carried out regeneration process, thus these means at the base material open space 5a of base material 5, regenerated cellulose 6 solidified, because can improve the close attachment intensity of base material 5 and regenerated cellulose so preferably.
Then, the drench poisture-penetrability of wet film of the sense of the present invention obtained by above-described method is described.
Fig. 5 a is that the sense representing involved by embodiments of the present invention 1 drenches the chart of the regenerated cellulose amount of wet film and the humidity interdependence of water vapour permeability, and Fig. 5 b is that the sense representing involved by embodiments of the present invention 1 drenches the chart of the serviceability temperature of wet film and the humidity interdependence of water vapour permeability.
Use Fig. 5 a and Fig. 5 b that the water vapour permeability of the drenched wet film 4 of sense is described.
In addition, water vapour permeability represents as humidity transit dose in these figures.This humidity transit dose is referred to and to be drenched the amount that the moisture weight of wet film 4 carries out specifying by the sense of per unit area as time per unit.
From Fig. 5 a, the drenched wet film 4 of sense just has the tendency that humidity transit dose increases gradually along with humidity rises.At this, observe the density 0.3 ~ 1.0g/cm relative to base material 5
3keep the drench humidity transit dose of wet film 4 of the sense of regenerated cellulose known, the recruitment of humidity transit dose time humidity raises 5% from 90% to 95% compared with when raising 40% from 50% to 90%, large 2 ~ 10 times.That is, under the high humility state of 90%, humidity transit dose sharply rises.This phenomenon results from the cellulosic molecule starting the regenerated cellulose be described at embodiment 1 to be configured to noncrystalline structure, its reason is that the moisture under the state of low humidity in air can not enter between the cellulosic molecule of noncrystalline structure, under the state of high humility due to the moisture in air enter into make swelling between molecule between cellulosic molecule and moisture become easily through.
Then, Fig. 5 b confirms that the sense that caused by temperature drenches the different result of wet film 4 performance.
From Fig. 5 b, if when comparing low temperature when (5 DEG C) and high temperature (23 DEG C), humidity transit dose globality step-down during low temperature.This can consider because temperature step-down is so the translational speed of moisture in air diminishes.
Just as described above, if sense regenerated cellulose being held in base material 5 drench wet film 4 when, can confirm to play water vapour permeability, the rate of change of the moisture-inhibiting ability in high humidity regions (humidity is 90 ~ 95%Rh region) becomes about 5 times of the moisture-inhibiting ability in low humidity region (humidity is 10 ~ 50%Rh region).
Have again, in above manufacture method, if be pre-mixed mould inhibitor for viscose fiber, then without the need to using the adhesive etc. of mould inhibitor in the wet film 4 that drenches in the sense finally formed, and regenerated cellulose can be kept with the state containing mould inhibitor, the infringement to the drenched wet performance of sense can not be caused, thus preferably due to adhesive.
In addition, as mould inhibitor, even if also undergo no deterioration from the view point of selection due to the strong basicity of viscose fiber and be insoluble in the material of water, there are the mineral-type mould inhibitors such as TBZ, silver, copper, zinc; The organic mould inhibitors such as triazine, Isoprothiolane, iprodione, thiabendazole, wherein, from the view point of being widely used as food additives, cheap, anti-mold effect is lasting, preferably uses TBZ.
(embodiment 2)
Fig. 6 is that configuration thoughts involved by embodiments of the present invention 2 drench the stereogram of fruit and vegetable box of wet film device.
Sense of the present invention drenches wet device 8 from installation operability when easily moving the viewpoint of the drenched wet film 4 of sense or manufacture from the view point of raising, preferably fixes with framework 9 and feels drenched wet film 4 around.This framework is that wet film 4 is fixed and the through sense of timber drenches for surrounding by the timber of needle-like being erected in framework 9.In addition, although be insert molded as other fixing means, but because can with ground very close to each other fixed frame 9 while of shaping, and because the air in fruit and vegetable box 1 is inherently by the drenched wet film 4 of sense, so from the view point of water vapour permeability can be obtained effectively, preferably fix the drenched wet film 4 of sense around with framework 9.

Further, fruit and vegetable box 1 possesses the fruit and vegetable box lid 3 that the drenched wet film 4 of sense is housed, but without the need to possessing fruit and vegetable box lid 3 especially, and drenched wet film device is felt in configuration at least one face, also can obtain same effect.Rear, side and bottom surface etc. are referred in this so-called at least one side.
In addition, fruit and vegetable box main body 2 because can manufacture with cheapness, so from the viewpoint be made up of the macromolecular material such as PP or PS or ABS for preferably.In addition, from the object of more wholesomely preserving fruits and vegetables, being blended in by antiseptic is also effective in these macromolecular materials.
In addition, heat from outside is absorbed heat by fruit and vegetable box main body 2, and make temperature reach the inside of fruit and vegetable box main body 2 temperature identical with outside fast, to prevent for the purpose of the condensation caused due to the temperature difference, preferably use stainless steel or the high metallic alloy of the such heat transfer coefficient of aluminium.In addition, about these metal materials, because have anti-microbial property, so from the viewpoint of more wholesomely preserving fruits and vegetables for preferably.
Sense for the present embodiment formed as mentioned above drenches wet film 4 and possess the fruit and vegetable box 1 of the drenched wet film 4 of sense, is described below to its action.
First, will the fruits and vegetables preserved be wanted to be positioned in fruit and vegetable box main body 2, by the airtight fruit and vegetable box main body 2 of fruit and vegetable box lid 3.At this, when do not arrange sense drenched wet film 4 owing to making the humidity of fruit and vegetable box inside more than 100% from the rising moisture out of fruits and vegetables, the moisture exceeded produces the problem of condensation in fruit and vegetable box main body 2 inside, makes the fruits and vegetables generation web rot of carrying out preserving due to this dew.But, in fruit and vegetable box main body 2 of the present invention, because fruit and vegetable box lid 3 is equipped with the drenched wet film 4 of sense, and because made the moisture of fruit and vegetable box main body 2 inside be penetrated into the outside of fruit and vegetable box main body 2 by the drenched wet film 4 of sense, so the humidity of fruit and vegetable box 1 inside can not more than 100% by the effect of the regenerated cellulose of the drenched wet film 4 of sense.For this reason, because the fruits and vegetables being stored in fruit and vegetable box main body 2 also web rot can not occur and can preserve under high humility state, so can to keep the state of freshness over a long time to preserve.
In addition, the fruits and vegetables amount being saved in fruit and vegetable box main body 2 few and from fruits and vegetables rising moisture out few in, by feeling the effect of the regenerated cellulose of drenched wet film 4, the humidity transit dose of the drenched wet film 4 of sense reduces and the amount of the humidity of externally releasing from fruit and vegetable box main body 2 reduces.Result is because the humidity of fruit and vegetable box 1 inside becomes the state remained unchanged, so can to keep the state of freshness over a long time to preserve.
By effect as above, even thus when the temperature change caused in the fruits and vegetables amount etc. occurred owing to being saved in fruit and vegetable box main body 2, also can according to the humidity of fruit and vegetable box 1 inside, by feeling the effect of the regenerated cellulose of drenched wet film 4, thus automatically adjust vapor transfer rate, so the constant next pre-anti-condensation of high humility in fruit and vegetable box 1 can be maintained.
