Description
Affiliated technical field
The utility model relates to the fresh-keeping product of using of a kind of improved fruit and vegetable, particularly relates to a kind of improved tin foil.
Background technology
At present, existing inside has the tin foil of Powdered storage chemical in the process of using, because comparing with the graininess storage chemical of equivalent weight, Powdered storage chemical wherein has big many surface areas, so effective fresh-keeping composition contained in the Powdered storage chemical will soon discharge light, this causes existing this tin foil to exist the short defective of effective fresh keeping time.
Summary of the invention
The purpose of this utility model provides the long improved tin foil of a kind of effective fresh keeping time.
The purpose of this utility model is to realize like this, a kind of improved tin foil, comprise first lamella and second lamella made with poromeric material that are bonded together mutually, distribution is arranged on the Powdered storage chemical bag shape cavity that is sticked into by first lamella and second lamella between first lamella and second lamella, and being placed on Powdered storage chemical in the Powdered storage chemical bag shape cavity, it also includes graininess storage chemical, graininess storage chemical bag shape cavity and is lower than the 3rd lamella that the poromeric material of first lamella is made with gas permeability; Wherein the 3rd lamella is bonded together with second lamella made from the gas permeability poromeric material identical with the 3rd lamella, the graininess storage chemical bag shape cavity distribution that is sticked into by the 3rd lamella and second lamella is arranged between the 3rd lamella and second lamella, and the graininess storage chemical is placed among the graininess storage chemical bag shape cavity.
Because it is less to be provided with surface area among the utility model, but the bigger graininess storage chemical of weight, it is slower that this graininess storage chemical discharges the time of wherein contained effective fresh-keeping composition, so the utlity model has long effective fresh keeping time; Simultaneously, because being used for second lamella of enwrapped granule shape storage chemical and the 3rd lamella is to make with the poromeric material that gas permeability is lower than first lamella that is used to wrap up Powdered storage chemical, therefore second lamella that gas permeability is lower and the 3rd lamella can further delay the time that the graininess storage chemical discharges wherein contained effective fresh-keeping composition, the utlity model has longer effective fresh keeping time thereby make; In addition, owing to kept Powdered storage chemical simultaneously in the utility model, it can satisfy the fresh-keeping initial stage to the big requirement of effective fresh-keeping composition expense simultaneously.

The specific embodiment
The utility model will be further described below in conjunction with drawings and Examples, a kind of improved tin foil, comprise first lamella 4 and second lamella 5 made with poromeric material that are bonded together mutually, distribution is arranged on the Powdered storage chemical bag shape cavity 2 that is sticked into by first lamella 4 and second lamella 5 between first lamella 4 and second lamella 5, and being placed on Powdered storage chemical 3 in the Powdered storage chemical bag shape cavity 2, it also includes graininess storage chemical 6, graininess storage chemical bag shape cavity 7 and be lower than the 3rd lamella 1 that the poromeric material of first lamella 4 is made with gas permeability; Wherein the 3rd lamella 1 is bonded together with second lamella made from the gas permeability poromeric material identical with the 3rd lamella 15, graininess storage chemical bag shape cavity 7 distributions that sticked into by the 3rd lamella 1 and second lamella 5 are arranged between the 3rd lamella 1 and second lamella 5, and graininess storage chemical 6 is placed among the graininess storage chemical bag shape cavity 7.
Effective fresh-keeping composition in graininess storage chemical 6 and the Powdered storage chemical 3 can discharge by first lamella 4, second lamella 5 and the 3rd lamella made from poromeric material 1; Because being used for second lamella 5 of enwrapped granule shape storage chemical 6 and the 3rd lamella 1 is to make with the poromeric material that gas permeability is lower than first lamella 4 that is used to wrap up Powdered storage chemical 3, so lower second lamella 5 of gas permeability and the 3rd lamella 1 graininess storage chemical 6 that can delay wherein to be wrapped up discharges the time of wherein contained effective fresh-keeping composition.
Fresh-keeping as required time length and single size of graininess storage chemical 6, the number that is placed on the graininess storage chemical 6 among each graininess storage chemical bag shape cavity 7 can be 1-20; Certainly more also passable; As shown in Figure 2, wherein the number of the graininess storage chemical 6 among each graininess storage chemical bag shape cavity 7 is one; The time length of graininess storage chemical 6 release effective fresh-keeping compositions that it contained is relevant with the surface area of its weight and Unit Weight.
The shape of graininess storage chemical 6 can be sheet, bar-shaped or spherical etc.
Powdered storage chemical 3 among the utility model is used to the fresh-keeping initial stage provides the fresh-keeping composition of mass efficient to use, and the graininess storage chemical 6 among the utility model is used to transport with the storage midium or long term and slowly provides effective fresh-keeping composition to use.
The diameter of the particle described in the utility model is much larger than the diameter of the fine particle that constitutes powder.
Poromeric material described in the utility model can be paper, nonwoven, cloth etc., and the difference of its permeability can realize by quantity and the size of controlling the micropore on it.
