Description
Technical field
The present invention relates to a kind of storage bag, especially a kind of Food garbage disposal bag for aerospace.
Background technology
In manned space mission, along with the progressively prolongation of flight time, astronaut after the meal remaining food refuse how to be treated as China's manned space flight must faced by problem.Because food refuse has, moisture is high, rich in nutrition content, provides desirable condition for germ increases breeding fast.The growth breeding of germ can cause food refuse putrid and deteriorated, thus produces peculiar smell, pollutes indoor environment further.How to avoid the generation of this kind of problem, thus ensure safety and Health in astronaut? if vacuumize process after sealing food refuse, place deoxidation reagent simultaneously and remove the residual oxygen of major part, then greatly can delay the growth reproduction speed of germ, slow down food refuse putrid and deteriorated, the food and extend rubbish storage time.Outside the requirement meeting the food and extend rubbish storage time, this kind of food-trash treatment mode also must meet the requirement used under microgravity environment, also must have high reliability, safety and less weight and volume simultaneously.In the patent published or document, the function that a kind of vacuum compression bag for the articles for use such as clothing, quilt has vacuumizing and compresses, and report more, but these inventions all can not meet microgravity under food refuse collect and storage request.This is mainly manifested in following three aspects: one is be connected insecure between air extractor with air valve, easily comes off; Two is do not have filtering installation in air valve, effectively cannot filter, easily cause air valve to block to swill; Three is do not have in air valve to design device or the position of depositing deoxidation reagent, is unfavorable for reducing oxygen remaining in compressed bag further.As at application number be 200820055126.9 utility application in, Jin Xiangyu etc. disclose a kind of mildew resistant vacuum compression bag, in the invention of this utility model, devise the moisture absorption mildew-resistant capsule that is equipped with moisture absorption chemical, the design of this capsule makes vacuum compression bag be provided with the function of mildew-resistant.If the weak point of this invention is that the material of bag is chosen as the material of high barrier, then do not need mildew-resistant capsule can play the effect of mildew-resistant equally.Be in the application for a patent for invention of 201010192333.0 at application number, Huang Jiahui discloses a kind of vacuum compression bag, bag and vacuum pump are mounted for one by this compressed bag, can be extracted out by the air in the article such as cotton-wadded quilt easily, thus avoid the trouble manually connecting vacuum pump.But each compressed bag configures cost and weight, volume that a vacuum pump considerably increases product undoubtedly, and again reduce the reliability of compressed bag, this cannot meet the characteristic requirements of space product.Be in the patent of invention of 201010253780.2 at application number, Shi Feng discloses a kind of vacuum garbage bag, this refuse bag is based on existing refuse bag, while utilizing double faced adhesive tape speed encapsulation technique, again according to bionics principle, vein valve check valve principle is applied to vacuum garbage bag, achieves the vacuum seal to rubbish, compression process.But the bag material of this invention is comparatively thin, is easily punctured by hard object, adopt the intensity of double faced adhesive tape sealing can not meet the requirement of space environment simultaneously.The present invention mainly designs food garbage reservoir bag in air valve, bone bar and limiting device etc., make it to be adapted at microgravity environment collection, storage food rubbish, the requirement that family collects, stores affaires can be met again, accomplish not only can save space and volume, the shelf-life of article can also be extended.
Summary of the invention
The air extractor being directed to existing vacuum compression bag be connected between air valve insecure, effectively cannot filter food and oxygen remaining in compressed bag can not be carried out deficiencies such as effectively removing, the invention provides a kind of food refuse reservoir bag that can be applied under space flight microgravity environment, when this food refuse reservoir bag can also be applied to mountain-climbing, tourism simultaneously food refuse collection and temporarily store.Described process bag comprises:
I () has the bag that foreign object inserts opening;
(ii) sealing element; Described sealing element comprises and is arranged at the bone bar slide fastener that foreign object inserts opening part, for the slide plate of pressing bone bar slide fastener, and for limiting the limiting device of slide plate position; With
(iii) the pumping section air valve of bag side is positioned at; Described air valve comprises valve body, vent plug and air valve cap.
Described valve body has flange arrangement, is connected on the upside of it with vent plug, and downside is connected with bag, forms gas channel; The upside of described valve body has cylindrical structure, and cylindrical structure arranges outside thread, and inner side has circular boss structure, and the center of boss structure has the through hole for gas being discharged bag, and the neighboring, upside of boss structure has convex annular bead structure.
Described vent plug is elastomeric pad, and the center of elastomeric pad has the projection can filling in described through hole, coordinates in order to form air-tightness; The outer rim of elastomeric pad covers described convex annular bead structure, coordinates in order to form air-tightness with convex bead structure under external thrust effect.
Described air valve cap arranges negative thread and is threaded with described cylindrical structure, in order to provide the thrust of elastomeric pad and convex bead structure.
Preferably, in described valve body, filtering net is set, in order to filter the fine particle of bag.
Preferably, described filtering net is embedded with deoxidation reagent.
Preferably, the order number of described filtering net is 40 ~ 200 orders.

Adopt storage bag of the present invention, can play the effect of vacuum storage, index is as follows:
1) bleed the degree of vacuum ≯-0.03MPa of sack after compression;
2) sealing-strength requires: heat seal strength ≮ 44.1N/15mm;
3) keep under sealing property :-90Kpa not leaking for 20 minutes;
4) slide plate normally can close number of times ≮ 120 time of bone bar slide fastener;
5) 5 years storage lives of deoxidation storage bag are compressed.
Compared with prior art, the present invention has following beneficial effect:
1) by arranging outside thread on the cylindrical structure of valve body, making it be threaded with the female pump bowl of another tool, can making to be connected firmly when bleeding between the two, not coming off;
2) due to the existence of filtering net, residue when bleeding in bag can not be drawn out of along with air-flow, thus blocking air valve or pollution pump bowl;
3) bleed after compression and have certain degree of vacuum in sack, and the deoxidation reagent be embedded in filtering net can remove oxygen remaining in bag further, reduces oxygen content.
