[Detailed description of the invention]

[0001]

[Industrial applications]

 The present invention relates to an improvement in safety and design in a gas lighter having a flame forming part and an ignition and combustion operating part on the upper part of a fuel tank.

[0002]

[Prior art]

 Conventionally, for example, in a gas lighter that is generally put on the market, in which the fuel tank is made of resin, a burner mechanism for ejecting fuel gas is provided at one end of the upper part of the fuel tank, and the burner mechanism and the flame ejecting section are burner mechanisms. The burner mechanism is covered with a windshield formed of a thin metal plate to protect the parts and prevent blowout due to wind, etc., or a flame is formed from the gas ejection part of the burner mechanism, or, as shown in FIG. A burner mechanism is provided in the upper part, and a flame forming part for forming a flame is provided from the opening C in the upper end face of the windshield B provided above the gas ejecting part of the burner mechanism. The operation part D for intentionally performing the ignition operation and the continuous combustion for igniting the jetted gas and the jetted gas, the windshield A formed of the thin metal plate of the flame forming part, the operation for performing the gas jetting, ignition and continuous combustion Parts are juxtaposed to each other And it has a configuration.

Further, a burner mechanism for ejecting fuel gas is provided on the upper part of the fuel tank, an intermediate case member is mounted on the upper part of the fuel container, and a flame is formed on the upper end surface of the intermediate case member for the purpose of protecting the burner mechanism part and wind resistance. There is also a configuration in which a windshield having an opening to be formed, an ignition mechanism, and an operation section for performing operations of fuel gas ejection, ignition, and continuous combustion are provided.

[0004]

[Problems to be solved by the device]

 However, in the above-mentioned conventional gas lighter, a metallic windshield provided in the flame forming part and an operating part for ejecting fuel gas to perform continuous ignition and ignition operation are provided adjacent to each other, so that after-ignition incense sticks or fireworks are ignited. If a longer continuous burning operation is performed, such as burning instead of lighting to ignite ordinary cigarettes, the heat of the combustion flame is transferred to the windshield with good thermal conductivity, and the windshield surface becomes a high temperature exceeding 100 degrees Celsius. However, since the adjacent operation part was operated with a finger, the finger during operation could come into contact with the metal windshield and get burned.

When a continuous combustion operation longer than usual is performed, the heat of the metal windshield heated by the combustion flame is transferred to the adjacent ignition mechanism section and operation section, and the ignition mechanism section and operation section are made of synthetic resin. If they are present, these members may soften and deform due to heat, which may cause parts to pop out or cause functional problems. Depending on obstacles such as non-automatic extinction of combustion flames, there was a possibility of an accident.

Further, since the windshield provided in the flame forming portion is a member formed by pressing a thin metal plate, the end face of the windshield becomes a fractured surface of the thin plate, and this fractured surface is adjacent to the operating portion for ignition and combustion. During operation, the finger could come into contact with the fracture surface, and the finger could be injured.

Further, the conventional gas lighter having a flame forming part and an ignition continuation combustion operating part on the upper part of the fuel container is composed mainly of a fuel container, a windshield and an operating member, so that the product property of the product is improved. To emphasize, the three parts of the fuel tank, the windshield and the operating member are colored or the surface is painted or printed to finish the product diversification. Each of the above members was subject to restrictions on appearance enhancement such as material and finish depending on its functional purpose such as gas resistance, pressure resistance, combustion resistance, and heat resistance.

The present invention has been made in order to solve the above-mentioned problems, and its purpose is to prevent a finger or the like from being burned or injured during an ignition and continuous combustion operation, and to configure the structure. It is intended to provide a gas lighter which is highly safe in that its members are not deformed or functionally damaged by heating, and which has a high commercial appearance.

[0009]

[Means for Solving the Problems]

 In order to achieve the above object, the gas lighter of the present invention has a burner mechanism for ejecting the fuel gas to the upper part of the fuel tank containing the fuel gas, an ignition mechanism for igniting the ejected fuel gas, and a continuation of ignition and combustion. In a gas writer provided with an operating mechanism for performing, a burner mechanism for ejecting fuel gas to form a flame is provided at one end of an upper portion of the fuel tank, and the burner mechanism section and the flame forming section are provided with an opening in the flame forming section. An operating member of an operating mechanism for performing ignition and continuous combustion was provided at the other end of the upper part of the fuel tank by covering with a windshield, and an intermediate member having a top surface portion was provided between the metal windshield and the operating portion. It has a characteristic structure. Further, in the present invention, the intermediate member having the top surface portion between the metal windshield and the operating portion is made of synthetic resin, and may be attached above the fuel tank by a snap fit.

[0010]

[Action]

 According to the structure of the present invention, when the operating portion provided at one end of the fuel tank is pressed, the valve of the burner mechanism is released and the fuel gas is discharged from the nozzle tip, and at the same time, the ignition mechanism is activated and the nozzle tip is pushed. The emitted fuel gas is ignited to form a combustion flame at the upper end face of the windshield provided around the burner mechanism section, and in order to continue combustion, the pressing operation of the operation section is continued. The fuel gas discharged from the burner mechanism nozzle generates combustion flame upward from the vicinity of the opening of the windshield upper end, and the heat generated from the combustion flame is transferred to the windshield made of thin sheet metal to heat the windshield member. The operation part that continues ignition and combustion is located from the windshield through the intermediate member, and the heat of the heated windshield is cut off by the synthetic resin with low thermal conductivity and the combustion flame There is no transfer of heat and there are no burns on the operating fingers. In addition, by placing an intermediate member that has a rounded end surface made of synthetic resin between the operating part and the windshield, the finger to be operated directly contacts the end surface of the metal windshield made of thin plate. Since it will not occur, it will not cause a cut or the like on the finger.

The intermediate member provided between the flame forming portion and the operating portion is such that the heat of the windshield heated by the generated flame is not transmitted to the operating portion and the end surface of the metal thin plate does not come into direct contact with the operating finger. For functional purposes, it is desirable to select a synthetic resin with a high heat resistance that has a low thermal conductivity and a soft feel for the material of the intermediate member. The desired shape and color can be obtained, and by changing the shape and color of the intermediate member, it is possible to easily produce products with a different appearance image, and diversify the products.
