Problems solved by technology

However, this method also requires manual work since workers manually manipulate the gas filling hose into the fuel filling hole and push the sealing cap by hand after the gas is fully charged.
In addition, the amount of gas leakage is also large and the sealing becomes poor

Embodiment Construction

[0020] refer to Figure 2A , The disposable lighter in the present invention includes a lighter body 1 and a fuel container 2 and an insert 10 forming the lighter body 1 . The insert 10 is provided at the open end portion of the fuel container 2 and welded to the contact surface of the fuel container 2 by an ultrasonic welding device. The valve 13 and the tube 12 are connected to the insert 10 part by penetrating the insert 10 . The upper part of the valve 13 is connected to the nozzle 14 . The spring 17 is inserted into a hole formed in the center of the insert 10, on which the flint 16 is placed. The ignition roller 15 is installed in contact with the ignition stone 16 . In actual operation, the flint 16, spring 17 and ignition roller 15 are preferably installed after the gaseous fuel is completely filled.

[0021] The fuel filling hole 11 is formed opposite to the nozzle 14 of the insert 10 and deepens in a multi-step form with different diameters along the depth direct...

Abstract

A disposable lighter assembling and fuel filling device for filling gas fuel automatically into the lighter is provided. The lighter includes a fuel container and an embedded member for closing the fuel container. The embedded member includes a fuel filling hole formed along the depth direction of the embedded member, a protruding part formed on the inner wall of the fuel filling hole and a sealing cap inserted into the fuel filling hole. The device includes a transfer part, a embedded member welding part for welding the contact part between the embedded member and the fuel container, a gas fuel filling part for filing the gas fuel into the fuel container, and a sealing part for inserting the sealing cap into the lower part of the protruding part in order to hook the sealing cap by the protruding part to push the sealing cap into the fuel filling hole. Therefore, because the work speed in increased by the insert welding work, the gas fuel filling work and the automatic sealing work, so the labor cost is reduced and the leakage of the gas fuel is furthest reduced.

Description

technical field [0001] The present invention relates to an assembly and fuel filling device for a disposable lighter, and more particularly, to a gaseous fuel filling hole formed in an insert of a fuel container of the lighter, and then plugging the filling hole with a sealing cap so that Disposable lighter assembly and fuel filling device greatly improving productivity and stability. Background technique [0002] Due to their low price and ease of use, disposable lighters are widely used. Traditional disposable lighters mainly use butane gas (n-butane, C 4 h 10 ). Butane gas becomes liquid below -0.5°C to prevent volatilization. Butane gas formed by liquid butane gas is manually filled through the open portion of the lighter fuel container. The opening part is plugged with an insert. Of course, in order to keep the strongly volatile butane gas stably in a liquid state, it needs to be kept at sub-zero temperatures or stored in special pressure tanks requiring high-cost...
