Description
Technical field
The utility model relates to the freshness protection package technology, refers to the vacuum fresh-keeping bag of a kind of Kaifeng repeatedly, repeated use, good seal performance especially.
Background technology
The vacuum fresh-keeping bag of making of plastic sheeting has become a kind of general fresh-keeping apparatus, is used for preserving food, medicine, tape and electronic component etc.Its structure comprises the bag of plastic film, at sack sealing arrangement is installed, bag wherein on one bag of face air-valve device is installed, the wherein one bag of face inwall at bag is shaped on the concavo-convex gas line that supplied gas is extracted out simultaneously.The vacuum fresh-keeping bag of prior art has the following disadvantages at least:
One, the sealing arrangement that is installed in sack has two types substantially:
One type is pressure-sealing zipper, and sack envelope is tight, and its sealing effectiveness significantly reduces with the increase of Kaifeng number of times, Kaifeng several times after, do not had sealing function substantially.
Type be clips in addition, sack is clamped, as Chinese patent " a kind of plastic bag sealing folder " disclosed (ZL02268214.7), it by be hinged together and can open two intermediate plates that can close and form, rectangular groove on the intermediate plate wherein, the middle part of groove have the projection of the sheet of contour with it together bending; It is the projection of contour sheet that the center is symmetrically distributed and consistent, isometric with its bending direction with aforementioned projection that twice are arranged on another sheet intermediate plate, and the end of two intermediate plates is provided with catch gear accordingly.Its complex structure, the productive costs height.This structure design use principle, painstakingly brute force repeatedly bends folded poly-bag mouth, and repeatedly the folding line of powerful bending can make the planeness of sack destroy, and the destruction of planeness means that this poly-bag has lost the vacuum seal condition, so this anchor clamps are not suitable for repeatedly usable vacuum fresh-keeping bag.
Two, the air-valve device of installing on wherein one bag of face of bag, structure are also complicated.As Chinese patent " a kind of family expenses vacuum fresh-keeping bag " disclosed (ZL200720055174.3), its air-valve device is included in the aspirating hole of the system of opening on one bag of face of bag, face toward folded successively bleed film and the envelope gas film of pasting of this aspirating hole in this aspirating hole outside, the film of bleeding is the double faced adhesive tape film that has aperture, and envelope gas film is that a side has at least a semicircle to cut the cushion compound of slight crack.The structure fabrication operation of this complexity is many, the cost height, and cushion compound is easily torn.
A kind of Kaifeng repeatedly of market demand, repeated use, good seal performance, bleed convenient and vacuum fresh-keeping bag simple in structure.
The utility model content
The utility model is intended to overcome the above-mentioned deficiency of the vacuum fresh-keeping bag of prior art, releases a kind of repeatedly usable vacuum fresh-keeping bag.It is Kaifeng, repeated use, good seal performance, the convenience and simple in structure of bleeding repeatedly.
For this reason, the utility model repeatedly usable vacuum fresh-keeping bag adopts following technical scheme:
Construct the utility model repeatedly usable vacuum fresh-keeping bag, comprise the bag and the clips of plastic film, the clips clamping is arranged at the sack of bag, wherein installing for bleeding and bleed back leak free air-valve device rapidly on one bag of face of bag; It is characterized in that: the inwall that the sack of clips position is set in the wherein clamping of one bag of face of bag is a smooth side, and the remainder of this bag face inwall is shaped on the concavo-convex gas line that supplied gas is extracted out, and the inwall of another of bag bag face is smooth side entirely; Its clips is the magnetic seal folder or is the arc clip clips; Described air-valve device is included in leaving on wherein one bag of face of position that clamping is provided with clips of bag and opens a plurality of A aspirating holes of system, and a plurality of A aspirating holes are arranged in an A circle; Also comprise a round rubber sheet, open system B aspirating hole at the home position of described round rubber sheet, described round rubber sheet is bigger than the diameter of described A circle, described round rubber sheet is installed on the described A circle outside and pastes mutually with described A circle, be that described round rubber sheet covers described A circle, and the B aspirating hole is facing to the home position of described A circle.
The mechanism of this air-valve device is, the valve of air pump (family expenses air pump) is relative with B aspirating hole on the described round rubber sheet, negative pressure when bleeding is impelled described round rubber sheet elastic deformation, and the difference of the deformation coefficient of described round rubber sheet and plastic film bag material, cause producing relief between A aspirating hole and the B aspirating hole, this relief is a passage of extracting air-flow out, and the gas in the bag just is drawn out of, and forms vacuum (in fact being the likelihood dummy status); Bleed when finishing, negative pressure from air pump valve direction disappears, described round rubber sheet elastic restoration, a plurality of A aspirating holes on the bag are by the shutoff of described round rubber sheet, (because A aspirating hole and B aspirating hole stagger on the planimetric position mutually) is that air-valve device seals automatically, makes to keep vacuum state in the bag.
Technique scheme is further set forth:
Described magnetic seal folder is two the parallel magnetic strips that can close of opening that are sticked mutually and put, and wherein a termination is connected through the hinge, and another termination is a free end.
Described arc clip clips comprises two sliver transvers section circular arc intermediate plates, the cross-sectional plane of described cross circular section arc clip is circular arc, described cross-sectional plane vertical length direction, and two the cross-sectional plane of described cross circular section arc clip is the identical circular arc of curvature, article two, described cross circular section arc clip can open can close parallel being sticked mutually in ground put, wherein the concave surface of a described cross circular section arc clip pastes mutually with another convex surface; Article two, a corresponding end of described cross circular section arc clip is the folded flexible connection of expansible, article two, another corresponding end of described cross circular section arc clip is that detachable fastening cooperates by snap close, and two described cross circular section arc clips are corresponding crooked along its length direction.
The edge of described round rubber sheet is shaped on a whole circle and pastes cushion rubber, makes described round rubber sheet be pasted on the A outer that described A circle stretches laterally by this stickup cushion rubber.
The utility model is compared with prior art, beneficial effect is: one, can repeated multiple times use, sealing property can not descend because of the increase of access times, because no matter be the magnetic seal folder, or arc clip clips, clamping dynamics to sack can frayedly not wait influence, even produces destructive catcher mark; Its two, simple in structure, effective: 1., for magnetic seal folder, two magnetic strips, simple in structure; 2., for the arc clip clips, two sliver transvers sections are the circular arc intermediate plate, and corresponding crooked along its length direction, structure really belongs to simple, and effect is fine, because arc surface can make laterally clamping longitudinally more balanced when clamping, is difficult for producing the blind spot of clamping; 3., the various schemes of the texture ratio prior art of this air-valve device all want simple, the different deformation characteristics of utilization plastic film and sheet rubber two kinds of materials, reach the design that A aspirating hole and B aspirating hole are staggered mutually make designs simplification on the planimetric position, production technology is become simply, also more convenient when bleeding.Its three, be applicable to and preserve food, medicine, tape and electronic component etc., purposes is wide, the vacuum fresh-keeping bag that can reduce prior art basically can only one-shot usage and the waste and the white pollution that cause.
