Abstract
Abstract The cigarette packet has an electric lighter for the cigarettes contained in the packet. The lighter is arranged at the closed end of the packet, which is positioned opposite the end from where the cigarettes are pulled out of the packet, and comprises an electric battery as well as two electrically conductive contacts which are connected to the +pole and the -pole of the battery respectively. Each of the cigarettes is provided at one end with a lighting part which can be brought into contact with the contacts and, as a result of the current which is then supplied by the battery, can be heated to a temperature which suffices to light the cigarette in question. So as to light the cigarettes when pulling them out of the packet, they are arranged in the packet in such a way that the ends provided with the lighting part face the closed end of the packet. Furthermore the one contact extends inside the packet away from the closed end of the packet to the end from where the cigarettes are pulled out of the packet, so that every cigarette, when pulled out of the packet, slides with the lighting part along this contact. The other contact extends inside the packet to the lighting part of each cigarette contained therein, and is connected to this lighting part in an electrically conductive manner until the cigarette has been pulled out of the packet by a certain distance.

Claims Analysis
Total Claims: 32
Claim 1
Independent Claim
226 words
A cigarette packet assembly including a packet having an open end and a closed end, a plurality of cigarettes and an electric lighter, which assembly comprises: (a) an electric lighter including an electric battery and a pair of electrical contacts associated with each cigarette, each pair of contacts being connected to the positive and negative poles of the battery; (b) a lighting part carried at the end of each cigarette adjacent the closed end of the packet when the cigarette is in a stored position, each lighting part being disposable in conductive relationship with a corresponding pair of contacts; (c) each pair of contacts including a first contact disposed in continuous conductive relationship with the lighting part and a second contact disposed out of conductive relationship with the lighting part when the cigarette is in its stored position; (d) the second contact extending towards the open end of the packet and disposable in conductive relationship with the lighting part when the cigarette is being pulled out of the packet through the open end, thereby closing the electric circuit of the battery and heating the lighting part to a temperature sufficient to light the cigarette; and (e) the first contact being disengageable from the lighting part for opening the electric circuit of the battery after the cigarette has moved through a predetermined distance from the stored position.
Claim 2
Dependent Claim
