Abstract
A vacuum compression bag belongs to the field of collective articles and comprises a bag body, a gripping chain and an air extraction device, wherein the air extraction device is arranged on the bag body, the gripping chain for sealing a bag opening is adhered to the inner side of the bag opening of the bag body through hot seal mode and comprises a concave gripping chain strip and a convex gripping chain strip which are matched for use, and two ends of each gripping chain strip adopt curved transition sections for leading the two ends thereof to be combined with the bag body through hot seal mode. The vacuum compression bag of the utility model has reinforced air tightness, thereby leading the sealing effect of the entire compression bag to be reinforced.
Description
Technical field
The utility model belongs to the articles for use field of taking in, particularly a kind of compressed bag.
Background technology
People's life now is more and more nervous, the living space is also more and more littler, so how the limited space of reasonable use becomes the problem that people more and more pay close attention to, with compressed bag of packing into such as thick and heavy clothing, quilts, with the air extraction in the compressed bag, cotton-wadded quilt clothing and bag can be combined closely, make the volume compression of bag arrive minimum, thereby greatly facilitate storage.But the leak tightness of these compressed bag ubiquity sacks is not good defective, often in the compressed bag air admission is just arranged after a time, can not reach good effect.Mainly show: to carry out heat seal when bonding, clip chain sheet end is a tack, occurs two right-angled corners in the hot pressing fusion at the clip chain two ends that the film that (1) constitutes compressed bag and locking sack are used, and film and the heat seal of clip chain sheet on the corner is bad, the formation leakage path.(2) pocket portion is one deck, because the air barrier of material itself causes poor sealing.
The utility model content
At the deficiencies in the prior art, the purpose of this utility model is to provide a kind of vacuum compression bag.
A kind of vacuum compression bag, comprise bag, clip chain and air extractor, described bag is provided with air extractor, the inboard heat seal of the sack of described bag is bonded with the clip chain that is used to seal sack, clip chain is made up of the concave, convex clip chain bar that is used, and arc-shaped transition section and bag heat seal are adopted together in described clip chain bar two ends.
Described air extractor is a check valve, comprises the air valve and the cover of dust of base, band check valve sheet, and base links to each other with bag, and the base top is provided with air valve, is stamped cover of dust on the air valve.
Described bag both can be single layer structure, adopted the coated film of PE film or the better nylon of barrier properties for gases and PE coating formation or the co-extrusion film of nylon and the formation of PE co-extrusion.
Described bag can also be the double-layer structure that is made of one deck inner bag and the outer bag of one deck, and every layer of co-extrusion film or PE film that can adopt nylon and PE co-extrusion to form, the co-extrusion film that PE and nylon form are that the PE that has co-extrusion to form in the one or both sides of nylon constitutes.
Described clip chain can be two, and parallel heat seal is adhered to sack, forms secondary seal to improve sealing effectiveness.
Described clip chain can also comprise a chuck, chuck straddle on sack two lateral walls and with two clip chains to middle jam-packed, by sealing fast with convenient to end pulling chuck.
The beneficial effects of the utility model:
(1) because the heat seal of camber line transitional structure is adopted in clip chain bar two ends and bag heat seal, avoided the heat seal that tack causes in the prior art not tight, can guarantee that therefore bag film and the heat seal of clip chain sheet are tightly air tight.
(2) bag adopts double-decker, has improved gas barrier property, can avoid in use making owing to one deck is damaged whole vacuum compression bag air leakage failure simultaneously again.
Description of drawings
Running condition scheme drawing when Fig. 1 is the utility model closure;
View when Fig. 2 opens wide for the utility model sack;
The heat seal view of clip chain bar and bag when Fig. 3 opens wide for sack;
Among the figure: 1 bag, 2 storings, 3 air extractors, 4 clip chain bars, 5 chucks, 6 camber line transition phases.
The specific embodiment
With a preferred embodiment the utility model is further described in conjunction with the accompanying drawings:
Embodiment: as shown in the figure, a kind of vacuum compression bag, comprise bag 1, air extractor 3 and seal the clip chain bar 4 of usefulness, the double-decker of bag 1 for constituting by inner bag and outer bag, bag 1 inner bag is the PE film, outer bag is the co-extrusion film of middle nylon both sides PE, and this unitized construction can reduce the permeability to air of bag, makes leak tightness strengthen; Bag 1 is provided with air extractor 3, air extractor 3 is check valves, the bag inner air is discharged to the outside, can stop outside air to enter again to inside, air extractor 3 comprises the air valve and the cover of dust of base, band check valve sheet, base links to each other with bag 1, the base top is provided with air valve, be stamped cover of dust on the air valve, unscrew air valve 1.5 circles before bleeding earlier, bleed, after the air in the bag 1 is exhausted with dust collecting fan or air extracting pump, extract suction nozzle rapidly out and tighten air valve, cover of dust is got final product by the jail; Bag 1 is provided with the clip chain that sack is sealed in two parallel being used to, and clip chain is made up of the concave, convex clip chain bar 4 that is used.The 4 paired heat seals of clip chain bar are in the sack inboard, bond together with bag, certainly the inner bag at sack place and outer bag also heat seal are together, as shown in Figure 3, clip chain bar 4 two ends at sack two ends and bag heat seal partly are one section camber line transition phases 6, clip chain bar 4 can fit tightly with bag like this, does not have the space, plays good sealing effectiveness.
Chuck 5 straddles on the sack lateral wall, be used for clip chain sheet 4 mutually in the middle of extruding its convex-concave structure is fastened togather sack sealing, if do not have chuck then can use the hand extruding sealing.
