Abstract

The utility model discloses a closed container capable of preventing contained liquid from contacting air. The technical scheme of the closed container is that an inner container is added in the liquid container and is made from flexible plastics; the inner container is matched with an inner chamber of the container when being folded; the inner container is classified into an air inflation type and a liquid filling type; an opening of the inner container is fixed on an air inlet or a liquid outlet of the container; and the liquid filling type container can be provided with an inner container suspension bar. The closed container has the benefits that the liquid in the container can be totally separated from the air at the outside as the closed container is provided with the plastic inner container, so that the liquid in the container can be prevented from being polluted by bacteria in the air, therefore, the quality guarantee period of the liquid in the container can be greatly prolonged and the liquid in the container can be more safe when being ate or used. The closed container is simple in design structure and sanitary in use and is not very high even when being used once. The design of the closed container can be widely applied to bottled water and other similar application fields.

Description

The leakproof tank of dress liquid-to-air contact in can avoiding

Technical field

The utility model relates to the leakproof tank of dress liquid-to-air contact in a kind of can the avoiding.

Background technology

Along with the raising of health of people consciousness, increasing people is using bottled water, how to guarantee that the hygienic quality of bottled water in preparation and use obviously become a crucial problem.Existing its structure of bottled water container is mostly more single, normally is provided with an admission port in the bottom of bucket, before bottled water is not enabled, and the admission port sealing.When bucket handstand is installed on the water dispenser, air inlet open, the negative pressure that produces by admission port makes the water in the bucket flow out swimmingly from water outlet.No matter this process is concerning the producer or user of bottled water, obviously makes perfect sense.But people do not notice, these air that newly replenish into are not very to clean, when the speed that people use fast, perhaps a spot of bacterium has little time breeding and has just been fallen by people's metabolism in the air, still, and when the frequency of people's water is very low, cause many opportunitys of wreaking havoc and multiplying for these bacteriums, in this case, no matter be that the outward appearance of water has no change, all can in human body, cause in various degree destruction and damage after drinking.For such problem, many people can be summed up as it bottled water and have problems in the process of preparation, hardly realize, all worries in the middle of this fully all are the misfortunes that unclean air is invited.If existing bottled water container is not improved, this problem may can't resolve forever.Certainly, this phenomenon is not limited to barreled drinking water, and the bottling liquid of the non-once use that other are many exists similar problem too.

Summary of the invention

Be to goal of the invention of the present utility model to provide the leakproof tank of dress liquid-to-air contact in a kind of can the avoiding.

The technical solution adopted in the utility model is: set up an inner bag in liquid container inside, this inner bag is made by flexiplast, and the inner chamber of its expansion shape and container is complementary; This inner bag can be designed as the Puffer-type inner bag, and the opening of inner bag is fixed on the admission port place of container.

This inner bag can also be designed to the topping up type, and the opening of inner bag is fixed on the liquid outlet place of container; An inner bag strut bar can also be set in inner bag, this strut bar is made by hollow plastic tube, have several apopores on the tube wall, its height should be enough to guarantee that the empty flat inner bag in back can not hinder the discharge of remaining liq from liquid outlet in the partially liq with going out, and can easily it be taken out from bottleneck again when liquid drains.

The fixed form of inner bag opening at container liquid outlet place has two kinds of designs, and a kind of screw-on threaded cap that is applicable to requires the inner bag setting at bung place long slightly in this case, and the opening of inner bag turns up at the liquid outlet place, and be by the screw thread of threaded cap that its extruding is fixing.Another kind is applicable to the spigot-and-socket container stopper, and the opening of inner bag invests on the inwall of liquid outlet, and the extruding by container stopper is fixed in the liquid outlet place.

The beneficial effects of the utility model are owing to be provided with the plastics inner bag, the liquid and the outside air of container can be isolated fully, avoided airborne bacterium to the pollution that liquid caused in the container, can improve the shelf-life of liquid in container widely, make the liquid edible in the container or use safer.The design is simple in structure, and health is not even if its cost of the disposable use of inner bag can be too high yet.The design can be widely used in bottled water or other various similar application, as other liquid food and pharmaceutical packing container.
