DESCRIPTION:
BRIEF SUMMARY
The invention relates to a cigarette packet with an electric lighter for the cigarettes contaned in the packet, of the type indicated in the introductory part of patent claim 1.
Such cigarette packets are known (U.S. Pat. No. 4,310,007). Here the lighter is provided in a separate compartment of the cigarette packet, so that the contacts extend in a plane parallel to a narrow side of the packet behind a circular opening in this narrow side of the packet. The cigarettes contained in the packet are lit in that a cigarette is pulled out of the packet and is then, with the end provided with the lighting part, put into the opening until it touches the contacts. The lighting part consists of an end layer of carbon fibres with a low electrical resistance followed by a layer of tobacco treated with potassium nitrate.
It is the aim of the invention to create a cigarette packet of this type which is improved in such a manner that the cigarettes contained therein are lit already when they are pulled out of the packet, as is known per se, i.e. in the case of cigarette packet with a friction lighter (U.S. Pat. Nos. 2,803,376 and 2,997,045).
This aim is achieved by the features indicated in the characterizing part of patent claim 1. Advantageous embodiments of the cigarette packet according to the invention are specified in the other patent claims.
The invention offers the advantage that in order to light the cigarettes contained in the packet, it is not necessary after pulling them out of the packet to again push them into a separate lighter, and that during the lighting no gases occur which could have an adverse effect on the taste, which as a rule is the case with the known cigarette packets with friction lighter.
In the following four embodiments of the cigarette packet according to the invention are described by way of example with reference to the drawing. Shown therein, in each instance diagrammatically are:
FIG. 1 a section through a first embodiment parallel to the two narrow sides of the packet;
FIG. 2 the section according to FIG. 1 through a second embodiment, in the region of the bottom closed end of the packet;
FIGS. 3 and 4, both sections according to FIG. 2 through a third embodiment and the view of the cigarette according to FIG. 3 in the direction of arrow IV;
FIG. 5 the section according to FIG. 2 through a fourth embodiment;
FIG. 6 part of the cross-section along line VI--VI in FIG. 1; and
FIG. 7 the cross-section according to FIG. 6 through a cigarette packet with two rows of cigarettes.
The cigarette packet A contains according to FIGS. 1 to 6 one row or according to FIG. 7 two rows of cigarettes B. So as to light the cigarettes B when pulling them out of the packet A, a lighter with an electric battery C as well as two electrically conductive contacts D and E is provided, which contacts are connected to the + pole and the - pole of the battery C respectively. When pulling them out of the packet A the cigarettes B cooperate with the lighter by means of a lighting part F which is provided at the one end of each cigarette B and which, when the cigarette B is pulled out of the packet A, is heated by the current supplied by the battery C to a temperature which suffices for lighting the cigarette B.
The cigarette packet A has a bottom, closed end A' and a top end A" for pulling the cigarettes B out of the packet A. The housing 1 of the cigarette packet A can be opened at the packet end A", and to this effect is provided, for example, with a tilt-up lid 2. The cigarettes B are arranged in the packet A in such a way that the ends provided with the lighting part F always face the closed end A' of the packet.
The battery C is a flat battery which is arranged on the bottom 3 of the housing 1. The one contact D extends inside the housing 1 away from the battery C towards the lid 2 and is formed by a foil 4 of metal which covers the adjacent broad side of the housing 1 on the inside. The foil 4 is sealed off from the lighting parts F of the cigarettes B contained in the housing by an insulating foil 5, which ex
