Abstract

The utility model discloses a storage container with an inner cover, comprising a container with an opening on the top part, an upper cover and an inner cover; the technical points of the storage container include that the inner diameter of the inner cover is less than the inner diameter of the container over 0.01 mm, so the inner cover can move up and down along with the quantity of the stored objects and is covered on the upper surface of the stored objects all the time, so as to reduce the contact between the air and the stored objects, delay the oxidation of the stored objects and prolong the expiration date. The storage container with an inner cover is applicable to the storage of frequently-taken particle and powder food, medicine and chemicals.

Description

The container for storing that inner cap is arranged

Technical field

The utility model relates to a kind of container for storing, a kind of container for storing that has loam cake and inner cap and inner cap to move up and down in container with what of stores of saying so more specifically.

Background technology

Existing container for storing such as bottle, jar, bucket etc., generally all have only a loam cake at the top, with such container storage food, medicine etc., the storage thing unavoidably contacts for a long time with air, especially those need often take the container of article, the easier oxidation deterioration of the article of being stored.

The utility model content

The purpose of this utility model, provide a kind of simple in structure, easy to use, can reduce the container for storing that air contacts with stores, be achieved through the following technical solutions: this container for storing comprises open-topped container, loam cake and an inner cap, described inner cap is less than inside diameter of vessel 0.01～1mm, thereby can in container, move up and down with what of stores, be pressed in the upper surface of storing thing all the time by deadweight.

The beneficial effects of the utility model are that the minimizing air contacts with stores, reduces degree of oxidation, extends the shelf life.

Among the figure: loam cake 1 open-topped container 2 inner caps 3 free handles 4 air extractor vents 5 stores 6

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described in detail: among Fig. 1, the internal diameter of container 2 is identical up and down, and loam cake 1 covers the suitable for reading of container 2, and stores 6 is arranged in the container 2, and inner cap 3 is pressed in the upper surface of stores 6 by deadweight.This moment, the air extractor vent 5 in the free handle 4 was blocked, and the air on the inner cap 3 is difficult for entering in the stores 6 below the inner cap 3.

When needs take out or deposit article, with portable free handle 4, when inner cap 3 is raised, the outlet of air extractor vent 5 also is higher than the top of inner cap 3, and as shown in Figure 2, this moment, air extractor vent 5 was unimpeded, inner cap air up and down can circulate, and inner cap can mention in container or put down easily.

This container for storing should be selected the stable material of physicochemical property such as pottery, enamel, dark glass for use, more helps storing guaranteeing the quality of thing.
