Pneumatic vacuum offset ink container

Abstract

The invention discloses a vacuum pneumatic offset ink container, which consists of cylinder and piston in the cylinder, wherein the ink outlet is opened on the front end of cylinder with inner lid on the ink outlet; the projected-column is set on the front end of piston to match the ink outlet; the air guide hole is set in the front end wall of piston; the inlet of air guide hole lies on the front end of piston and the outlet lies on the peripheral side face of piston. The container can adjust the ink, which realizes vacuum package and storage due to draining the air between piston and ink.

Description

technical field

[0001] The invention relates to an ink container, in particular to a vacuum pneumatic offset printing ink container which can be used in offset printing and can be vacuum-packed and stored, and the ink can be ejected pneumatically. Background technique

[0002] In the printing industry, the traditional offset printing ink packaging container is a cylindrical iron can formed by pressing tinplate. It consists of two parts: the tank body and the upper cover. Put the lid on. This kind of offset printing ink tin can container packaging has the following disadvantages:

[0003] 1. The transportation is inconvenient, and it can only be placed flat during transportation and loading and unloading, otherwise the ink will leak due to the tilt or inversion of the tank body;

[0004] 2. The plastic film is used to cover and seal the packaging. The ink around the tank has a poor sealing effect and a chemical reaction with the air for a long time, resulting in skinning on...
