Description
Technical Field
The invention relates to the field of packaging, in particular to an environment-friendly storage tank body device and a using method and application thereof.
Background
The binary package is a multiple protection package system consisting of a valve, a bag, an aluminum tank or an iron tank, the agent and the propellant are separately packaged in respective containers, the complexity of the formula is reduced, the propellant is not released during use, and the influence on safety and environment is reduced.
The binary package developed by continuous Can corp. in 1956 was: a traditional tinplate aerosol can is provided with a resin bag, a propellant is filled between the bag and the can, and the propellant is filled between the bag and the can. The bottom of the tank is provided with a small hole for filling propellant, and the tank is sealed by a rubber plug after filling.
The binary package developed in 1962 by American Can corp. was: a piston made of high molecular material is arranged in the aerosol can, and the piston is tightly matched with the can and can slide up and down along the wall of the can. The upper part of the piston is filled with propellant, and the lower part of the piston is filled with propellant. The bottom of the tank is provided with a small hole for filling propellant, and the tank is sealed by a rubber plug after being filled. Sometimes the product has a heavy feeling. The propellant under the piston may permeate upwards and the dose may also leak downwards.
In 1977, binary packaging was gradually improved and perfected to have a total of type 4, and only type 4 was produced. A small aluminum tank made of pure aluminum is embedded in the common aluminum tank. The small aluminum cans are filled with the propellant, and the propellant is filled between the two aluminum cans. The propellant is filled from a small hole at the bottom of the tank and sealed by a rubber plug after being filled. Any possible infiltration is prevented. It is especially suitable for high viscosity product. However, the cost is high.
Several companies in swiss in the 80 s developed, the most successful so far being EP Spray. The valve body is connected with a plastic or aluminum-plastic composite bag, the bag is filled with the agent, and compressed gas is filled between the bag valves. And by adopting the under-cover filling technology, the tank bottom does not need to be perforated, so that the leakage chance is reduced. The content discharge rate is affected by many factors. The filling speed of the dose is slower. However, the cost is high.
Therefore, it is very necessary to develop a new environment-friendly storage tank device by improving and creating the structure and material.
