Description
Technical field
The present invention relates to a kind of storage bag, especially a kind of space flight is processed bag with food garbage.
Background technology
In the manned space flight task, along with the progressively prolongation of flight time, how astronaut's remaining food refuse after the meal is treated as the problem that China's manned space flight must be faced.Because food refuse has, moisture is high, nutritional labeling abundant, for the breeding of germ rapid growth provides desirable condition.The growth breeding of germ can cause food refuse putrid and deteriorated, thereby produces peculiar smell, further pollutes indoor environment.How to avoid the generation of this class problem, thereby guarantee safety and Health in the astronaut? if vacuumize processing after food refuse is sealed, place deoxidation reagent simultaneously and remove most of residual oxygen, can greatly delay the growth reproduction speed of germ, slow down food refuse putrid and deteriorated, the food and extend rubbish storage time.Outside the requirement that meets the food and extend rubbish storage time, this kind of food-trash treatment mode also must meet the requirement of using under microgravity environment, also must have high reliability, safety and less weight and volume simultaneously.In the patent of having published or document, the function that a kind of vacuum compression bag for articles for use such as clothing, quilts has vacuumizing and compresses, and report morely, but all can not meeting under microgravity food refuse, these inventions collect and storage request.This is mainly manifested in following three aspects: the one, between air extractor and air valve, be connected insecurely, and easily come off; The 2nd, there is no filtering installation in air valve, can't effectively filter swill, easily cause air valve to stop up; The 3rd, the device or the position that in air valve, do not have design to deposit deoxidation reagent, be unfavorable for further reducing remaining oxygen in compressed bag.In the utility application that is 200820055126.9 at application number, Jin Xiangyu etc. disclose a kind of mildew resistant vacuum compression bag, designed a moisture absorption mildew-resistant capsule that the moisture absorption chemical is housed in the invention of this utility model, the design of this capsule function of mildew-resistant that made vacuum compression bag have.If the weak point of this invention is the material of bag and is chosen as the material of high barrier, do not need the mildew-resistant capsule can play the effect of mildew-resistant equally.In the application for a patent for invention that is 201010192333.0 at application number, Huang Jiahui discloses a kind of vacuum compression bag, this compressed bag is mounted for one by bag and vacuum pump, can be easily the air in the article such as cotton-wadded quilt be extracted out, thereby has been avoided the trouble of manual connection vacuum pump.But vacuum pump of each compressed bag configuration has increased the cost of product and weight, volume undoubtedly greatly, reduced again the reliability of compressed bag, this can't meet the characteristic requirements of space product.In the patent of invention that is 201010253780.2 at application number, Shi Feng discloses a kind of vacuum garbage bag, this refuse bag be take existing refuse bag as basis, when utilizing double faced adhesive tape speed encapsulation technique, again according to bionics principle, vein valve check valve application of principle, in vacuum garbage bag, has been realized to vacuum seal, the compression to rubbish processed.But the bag material of this invention is comparatively thin, easily by hard thing, punctured, the intensity that simultaneously adopts double faced adhesive tape to seal can not meet the requirement of space environment.The present invention mainly designs the food garbage reservoir bag at aspects such as air valve, bone bar and limiting devices, make it to be adapted at microgravity environment collection, storage food rubbish, can meet again the requirement that family collects, stores affaires, accomplish not only can save space and volume, can also extend the shelf-life of article.
Summary of the invention
Between the air extractor that is directed to existing vacuum compression bag and air valve, is connected insecure, can't effectively filter and oxygen remaining in compressed bag can not be carried out to the deficiency such as effective removal food, the invention provides a kind of food refuse reservoir bag that can be applied under the space flight microgravity environment, the collection of food refuse and temporary transient storage when this food refuse reservoir bag can also be applied to mountain-climbing, tourism simultaneously.Described processing bag comprises:
