Abstract

The utility model relates to a vessel cover with a scalable sleeve, comprising a cover body, a sleeve, a preform, which is characterized in that: multi-grade sleeves gradually enlarged from top to bottom are connected with the cover inner; bottom of last grade sleeve is provided with a preform which is opened with a plurality of small holes or is reticular shape; since the sleeves are enlarged from top to bottom, the preform connected with the last grade sleeve is moved up and down with the sleeve by means of solid gravitation and buoyancy, enabling the preform to press the solid in liquid so as to keep soakage position to avoid being dried-up or deterioration.

Description

The container lid that has scalable sleeve

Technical field

The utility model relates to a kind of container lid that has scalable sleeve.

Background technology

Existing container lid only plays and hides or sealing function, the solids that floats in the container on the liquid level can not be pressed onto below the liquid level, the lid that has has fixing netted projection, solids can be covered, but be difficult for taking, putting, and the height of netted projection can not change.

Summary of the invention

The purpose of this utility model is in order to overcome the shortcoming of existing lid, to provide a kind of solids that can will float to when covered container on the liquid level to be pressed onto the container lid of the scalable sleeve below the liquid level.

The technical solution of the utility model is, is connected with the multistage sleeve that level increases of satisfying from top to bottom in the lid of container, is equipped with one under the final stage sleeve and has a plurality of apertures or be netted compressing tablet.

Because sleeve is to satisfy level from top to bottom to increase, and by means of the buoyancy of gravity and solid, moves along with moving up and down of sleeve with final stage sleeve bonded assembly compressing tablet, and compressing tablet is pressed in solids below the liquid level all the time, keeps the dipping position, avoids dry or rotten.

Description of drawings

Lid view when Fig. 1 extends for sleeve;

Lid view when Fig. 2 shrinks for sleeve;

Fig. 3 is a lid running condition scheme drawing.

By shown in Figure 1, the utility model is made up of lid 1, sleeve 2, compressing tablet 3, is characterized in, is connected with from top to bottom in the lid 1, satisfies the multistage sleeve 2 that level increases, and is equipped with one under the final stage sleeve and has a plurality of apertures or be netted compressing tablet 3.Fig. 1, the 2nd represents sleeve when elongation respectively and the state of lid when shrinking, Fig. 3 represents the lid running condition, after lid 3 fastened container, the retractility of sleeve 2 can make compressing tablet 3 that the solids in the container 4 is pressed and be immersed in liquid level below 5, makes solids be in impregnation state all the time.

Claims

1, a kind of container lid that has scalable sleeve is characterized in that, is connected with the multistage sleeve (2) that level increases of satisfying from top to bottom in the lid (1), is equipped with one under the final stage sleeve and has a plurality of apertures or be netted compressing tablet (3).
