Abstract: A portable, handheld lighter assembly for lighting a lighting end of a rolled tobacco product, such as a cigarette or a cigar, includes an elongated body formed with opposed first and second channels formed on either side of a combustion zone and a stop formed in the elongated body. The combustion zone traverses the stop so as to couple the first channel in gaseous communication with the second channel. The stop restricts movement of a rolled tobacco product into the second channel from the first channel and restricts movement of a rolled tobacco product into the first channel from the second channel. A lighter is coupled to the elongated body and is for applying lighting heat to the combustion zone at the stop for lighting a lighting end of a rolled tobacco product applied against the stop in the combustion zone from the first channel or the second channel.

Abstract: A piezoelectric lighter with a child resistant ignition mechanism which prevents accidental ignition and ignition by unintended users and by minor children under the age of 5 years. The safety ignition mechanism is an activation device that requires two displacements in order to ignite the lighter. The displacements are achieved by applying a continuous and increasing force to the activating component in order to ignite the lighter. The first displacement unlocks the ignition device and the second displacement initiates simultaneously an electrical discharge and a fuel discharge, which results in a flame. Whenever a user discontinues the application of force to the activating component, the ignition mechanism returns to an inoperable, locked position. The effectiveness of this activating device in resisting the manipulations of children under the age of 5 years has been established by tests performed pursuant to the requirements of the United States Consumer Product Safety Commission.

Abstract: A lighter includes a liquid gas container having an inside formed with a receiving space, a press member pivotally mounted on the liquid gas container, and a control member movably mounted in the receiving chamber of the press member. Thus, the slide knob has to proceed a substantially L-shaped movement to trigger the igniter and to light the lighter, so that the lighter cannot be operated easily and unintentionally, thereby providing a double safety effect. In addition, the control member is integrally formed with the slide knob and the locking flange, so that the slide knob co-operates with the locking flange to perform the locking and unlocking actions conveniently and actually, thereby enhancing operation of the safety switch structure of the lighter.

Abstract: A two-stage safety arrangement for a cigarette lighter of the piezoelectric type having a case that houses a flammable liquid container, gas release mechanism, and piezoelectric ignition element. The safety arrangement includes an ignition cover that covers the gas release mechanism, a striking lever, and a release button. To operate the lighter, a user must first depress the release button and use an upward movement to release the ignition cover and reveal the gas release mechanism. Next, the user must simultaneously depress the release button and push the striking lever rotatably downwards and away from the gas release mechanism in order to actuate the piezoelectric ignition element. Use of both hands to depress the release button and pry back the striking lever from above, near the gas release mechanism, is further prevented by providing a raised safety ridge to prevent a user from gripping the edge of the striking lever near the outlet of the gas release mechanism.
