Description
Technical Field
The utility model relates to a fresh-keeping tank convenient to cover, and belongs to the technical field of fresh-keeping boxes.
Background
The fresh-keeping jar has sealing feature, can isolate the jar with the external world, make the article of storing not receive the pollution of external air, moisture, bacterium, dust etc. the current fresh-keeping jar generally includes the open jar body in top and can seal the cover on the cooperation jar body, wherein the cover contains the apron that covers jar body opening, locate the annular perisporium at apron back, and locate the sealing washer on the annular perisporium, the sealing washer on the current cover is apart from the apron certain distance, the annular perisporium at apron back inserts the jar body and makes the sealing washer and can utilize the elasticity of sealing washer to seal down the cover chucking on the jar body after making the internal wall contact in the jar with the internal wall of jar, but the sealing washer of cover has realized sealedly after the internal wall contact of jar, in the continuous process of moving down, jar body storage space is being reduced and jar internal air can not be discharged, lead to the internal atmospheric pressure of jar to be greater than jar body's atmospheric pressure, jar lid is difficult to cover tightly.
Disclosure of Invention
The utility model aims to provide a fresh-keeping tank convenient to cover, and the tank cover can keep the air pressure inside and outside the tank body balanced in the process of covering the tank body, so that the tank cover can cover the tank body tightly, and the defects in the prior art can be overcome.
The technical scheme of the utility model is as follows: the utility model provides a fresh-keeping jar convenient to lid closes, includes the jar body and cover, the jar body is the open container in top, and the cover contains the apron, locates the annular perisporium at apron back and locates the sealing washer on the annular perisporium, and the cover stretches into the jar internal sealing washer chucking seal that utilizes through the annular perisporium at back, the exhaust hole has been seted up on the annular perisporium, the exhaust hole is located the sealing washer top, and the apron back is realized the closing cap with jar body contact.
The tank body is further in a cone shape with a big top and a small bottom.
Further, an annular clamping groove is formed in the annular peripheral wall, and the sealing ring is clamped in the annular clamping groove.
Further, the periphery of the cover plate extends upwards to form an annular periphery.
And a perspective window is embedded on the tank cover.
By implementing the utility model, when the tank cover is covered with the tank body, the annular peripheral wall at the back of the cover plate is inserted into the tank body to enable the sealing ring to be in contact with the inner wall of the tank body, and then the cover plate is continuously moved downwards to enable the cover plate to be in contact with the top of the tank body to finish the cover, in the process, air in the tank body can be discharged from the exhaust hole, so that the air pressure in the tank body and the air pressure outside the tank body are always balanced, and the tank cover can be conveniently and smoothly covered on the tank body by using the sealing ring.
