A locking member includes a locking arm disposed in the ignition cavity and an operation button slidably mounted on an ignition button. A resilient element is adapted for applying an urging pressure against the locking arm so as to normally retain the locking arm in a locking position. In which, in the locking position, the locking arm blocks up the ignition button from ignition. In order to ignite the piezoelectric lighter, a user's thumb must operate the operation button for moving the locking arm to an unlocking position. Then, the user is able to push the ignition button downwardly to ignite the piezoelectric lighter.

Abstract: An everlasting candle comprising a wax body with a recessed hollow in its top for receiving an insulating container, and a smaller holding container with an annular rim set within the insulating container and communicating with the insulating container only by the rim (thereby to provide an insulative airspace between the two containers), the holding container being suitably dimensioned to replaceably receive a tea light votive candle. In use, the replaceable tea light votive candle within the everlasting candle burns with the same flame as a conventional paraffin candle, and will be liquefied and consumed during use. However, since the main wax body of the everlasting candle is separate and insulated from the replaceable tea light votive candle, the wax body of the everlasting candle will not be liquefied or consumed.

Abstract: An igniting rod which ignites by the operation of an operating member comprises a lock member for locking said operating member during a non-use state. The igniting rod automatically returns to a locked state after ignition. The invention improves operability, simplifies assembly and reduces the number of parts by eliminating an urging member.

Abstract: There is disclosed a novel flat heating surface type gas stove which is capable of heating a heating substance across a heat resistant glass at a practically applicable heating efficiency, thereby overcoming any inconvenience resulting from the exposure of flame and facilitating the cleaning of the gas stove. This gas stove 10 comprises a heat resistant glass top plate 12 which is disposed over a burner 15, wherein a gas-permeable porous body 40 is disposed below said top plate 12, and a space between said top plate 12 and a surface of said gas-permeable porous body 40 is assigned to a combustion space S.

Abstract: A method for mounting a wick within a wick sustainer is disclosed. The sustainer has a base, a barrel and a passage that extends through the sustainer. The passage has an upper region occupied by the wick and a lower region occupied, at least partially, by the sealant. Sealing the lower region of the passage is accomplished by injecting the sealant into the passage, thereby preventing the fuel from contacting the portion of the wick that is retained in the upper region of the passage. Fuel reaches the flame of the burning wick only through the portion of wick not held in the sustainer, so the flame is extinguished once the fuel descends below the top of the sustainer.
