Reduce remaining aerosol canister

Technical Field

The application relates to the technical field of airtight packaging containers, in particular to an aerosol can capable of reducing residue.

Background

At present, an aerosol can is an airtight packaging container with a spray valve and a spray propellant, and is generally made of high-strength steel, aluminum, plastic or glass.

In view of the above-mentioned related art, the inventors have considered that there is a drawback that the amount of the remaining aerosol can content is large.

SUMMERY OF THE UTILITY MODEL

In order to reduce aerosol can inner content in aerosol can's residue, this application provides a reduce remaining aerosol can.

The application provides a reduce remaining aerosol canister adopts following technical scheme:

a aerosol can capable of reducing residue comprises a can body, a can cover arranged at the top end of the can body, a nozzle arranged on the can cover, a guide pipe with one end detachably connected with the nozzle and a counterweight drainage piece detachably connected with the other end of the guide pipe; and a drainage hole is formed in one end, far away from the catheter, of the counterweight drainage piece.

Through adopting above-mentioned technical scheme, when using the aerosol canister, can rock jar body earlier and make configuration drainage piece drive the pipe and stir liquid product, make its mix more abundant even, draw the remaining liquid product of internal bottom of jar in the pipe with counter weight drainage piece to finally form aerial fog to the nozzle blowout via the pipe, reduce the residue of content at internal bottom of jar.

Optionally, the bottom surface of the tank body is an arc-shaped surface which is arched upwards.

By adopting the technical scheme, the bottom surface of the tank body is an arc-shaped surface which is arched upwards, the inner content of the aerosol can be prevented from being gathered on the bottom surface of the tank body, the configuration drainage piece can only be positioned at the lowest point of the arc-shaped surface under the action of gravity, and the inner content at the lowest point is led out of the pipe body through the guide pipe.

Optionally, the size of the opening of the tank body is gradually reduced along the direction from top to bottom.

By adopting the technical scheme, under the condition of equal height, the amount of the content corresponding to the space at the bottom of the tank body is smaller than that corresponding to the top of the tank body, so that the storage amount of the content at the bottom of the tank body is less, and the residue of the content is reduced.

Optionally, a plurality of arc-shaped concave surfaces are arranged on the outer side surface of the tank body close to the top end along the circumferential direction.

Through adopting above-mentioned technical scheme, the sunken face of arc more is fit for people's hand and grips the jar body, and it is more convenient to use and grip the aerosol canister.
