The specific embodiment
In conjunction with the accompanying drawings the present invention is described in further detail below by the specific embodiment.
As shown in Figures 1 to 4, present embodiment preservative film assembly comprises natural complex fresh-keeping film 4, cylinder 5 and first locking piece 6.Natural complex fresh-keeping film 4 comprises preservative film layer 1, the first intensity enhancement Layer 2 and the second intensity enhancement Layer 3 of compound one.Preservative film layer 1 can adopt existing preservative film, and as existing polyethylene preservative film, polyvinylchloride preservative film or PVDC Fresh Keeping Film, perhaps other can play the preservative film of preservation.Preservative film layer 1 has opposite first 11 and second surface 12.The first intensity enhancement Layer 2 is attached to first surface 11, the second intensity enhancement Layers 3 of preservative film layer 1 second surface 12 attached to preservative film layer 1.First and second intensity enhancement Layer 2,3 is made by the soft material that can reel, and the intensity of this first and second intensity enhancement Layer 2,3 is greater than the intensity of preservative film layer 1.This first and second intensity enhancement Layer 2,3 can be nonwoven fabrics.Because natural complex fresh-keeping film 4 has first and second intensity enhancement Layer 2,3, so can strengthen the service life of the bulk strength and the prolongation natural complex fresh-keeping film of natural complex fresh-keeping film.
Natural complex fresh-keeping film 4 is on cylinder 5, and end wise, natural complex fresh-keeping film 4 have installation end and pulling end, and this installation end is connected on the cylinder 5, and this installation end can be fixing with cylinder 5, and first locking piece 6 is fixed on this pulling end.Cylinder 5 can have rotating shaft 8, this cylinder 5 can be rotatably installed on the carrier by this rotating shaft 8.Can also be provided with existing elasticity turning gear on the cylinder 5, during pulling natural complex fresh-keeping film 4, cylinder 5 forward rotation, the elastic recoil device is compacted; When unclamping natural complex fresh-keeping film 4, the elastic recoil device recovers deformation, makes cylinder 5 backward rotation and regains natural complex fresh-keeping film 4.
Preservation device with this preservative film assembly also comprises box body 7, and this box body 7 has the opening 71 that is positioned at the top, and this opening 71 has first end 73 and second end 74.Preservative film assembly 4 can have one, and the cylinder 5 of this preservative film assembly is rotatably installed in first end 73 of this opening 71 by rotating shaft 8.Box body 7 can also have pack this sliding tray 72 in the end of sliding tray 72, the first locking pieces 6 between first end 73 and second end 74 in, make this first locking piece 6 and sliding tray 72 bearing fits.Second end 74 of box body 7 also be provided with can with second locking piece 75 of first locking piece, 6 lock fit.
When preservation device was opened, the preservative film assembly was positioned at first end 73 of this box opening, and the opening 71 of box body opens wide, and the vegetables and fruits food that the user can be fresh-keeping with needs is put into box body 7; In the time of need closing preservation device, the pulling end of pulling natural complex fresh-keeping film 4, first locking piece 6 slides in sliding tray 72, after 6 motions of first locking piece put in place, first locking piece 6 and 75 lockings of second locking piece, the opening 71 of box body is realized that by natural complex fresh-keeping film 4 complete closed the aqueous vapor adjusting and the high humidity of preservation device is fresh-keeping.
For the preservative film assembly, can be only at the first surface cohesive resistance enhancement Layer of preservative film layer, also can be only at the second surface cohesive resistance enhancement Layer of preservative film layer, or on first and second surface cohesive resistance enhancement Layer simultaneously.Intensity enhancement Layer attached to first surface or second surface can only have one deck, also stacked multilayer can be arranged.For material, the thickness of intensity enhancement Layer, can require according to the bulk strength of natural complex fresh-keeping film to design, select.
For the preservative film assembly, natural complex fresh-keeping film is on cylinder, and the pulling end of this natural complex fresh-keeping film is provided with first locking piece, structures such as this first locking piece such as magnet, the viscous body with viscosity or buckle.Box body can be provided with second locking piece that cooperates with first locking piece.
For preservation device, it can be for laterally opened, promptly only first end of box opening or second end are provided with the preservative film assembly, by second end or first end of pulling natural complex fresh-keeping film to opening, make natural complex fresh-keeping film enclosed box body opening, when this kind mode, second end of box opening can be provided with second locking piece that cooperates with first locking piece.Preservation device also can be opposite opened, and promptly first end of box opening and second end are equipped with the preservative film assembly, when needing the enclosed box body opening, spurs natural complex fresh-keeping film in opposite directions, makes first locking piece on two natural complex fresh-keeping films cooperate locking to get final product.
Above content be in conjunction with concrete embodiment to further describing that the present invention did, can not assert that concrete enforcement of the present invention is confined to these explanations.For the general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
