Coating device

Abstract

The invention provides a coating device capable of completely stopping the air invasion of connecting parts of a fluid conveying pipe mechanism and an accepting container or a pressurized tank, etc. The coating device is provided with pressurized tank, a compressed air feed mechanism for supplying compressed air for the pressurized tank, a plastic container arranged in the pressurized tank, a fluid conveying pipe mechanism with one end communicating with an open part of the plastic container and a coating nozzle mechanism connecting with the other end of the fluid conveying pipe mechanism. The plastic container possesses a plastic container main body, a long strip flow component and a sealing inserting mechanism. The plastic container main body is flexible and is provided with a wide opening part, the inner of which is filled with viscous liquid which is pressured and flattened to pressure eject from the opening part. The long strip flow component is arranged in the opening part in a way of extending in the plastic container main body and forms an ejection flow path when the viscous liquid is pressured to eject.

Description

technical field [0001] The present invention relates to an improved applicator having a plastic container for applying a viscous liquid, especially a moisture-curing type adhesive curable composition or an oxygen-cured type adhesive curable composition. It is effectively used when the adhesive curable composition is contained in a flexible bag or container, and pressure is applied from the outside to deform and shrink the bag or container, and the viscous liquid inside is discharged to the outside for coating. Background technique [0002] Conventionally, in a coating device for applying a moisture-curable adhesive or an oxygen-curable adhesive, since the adhesive is cured in contact with air, if the adhesive scatter, it will occur at the point where it scatter. Direct curing causes problems such as contamination, so it is necessary to apply the adhesive in a state where it does not come into contact with air.

Problems solved by technology

[0005] The above-mentioned Patent Documents 1 and 2 are all devices for applying liquids that are not suitable for contact with the air, but due to the gap between the liquid delivery pipe mechanism such as a hose and a pipe (tube) and the connection part such as a storage container and a pressurized container (pressurized box), The sealing structure does not necessarily adopt a strict mechanism, so various accidents cannot be avoided due to the intrusion of air from the connection part and the solidification of the liquid
