| 20090188945 | SILICON GEL DISPENSING DEVICE - A silicon gel dispensing device has a barrel connected with a compressor and having a discharging tube, a container mounted inside the barrel and connected securely to the discharging tube and a driver mounted beside the barrel and having an extendable axle attached to a piston of the container. The axle selectively pushes the piston to keep the piston closely abutting the silicon gel inside the container. So that high-pressured air inside the barrel for pressuring the piston is hardly permeating through a slight gap formed between the container and piston. Thus bubbles mixed with the silicon gel are avoided and silicon gel residue and uneven application surface occurring due to bubbles are effectively prevented too. | 07-30-2009 |
