• G 9216456.0 discloses a packaging for fireworks articles, which is designed as a quiver and can also be used as a launching device. It is also proposed here to use ring ignition, which is formed from a burning fuse or from a self-adhesive tape coated with an ignition agent. The firings of the fireworks items are wrapped with the fuse or with the self-adhesive tape. The length of the fuse in combination with its nature thus determine the timing of the ignition process.
• German utility model G 29504875.1 describes packaging for fireworks articles which has a receiving part for the fireworks articles, which is itself designed as a launching device.
• Ignition uses a fuse attached to the fireworks items.
• such a fuse is sensitive to moisture and temperature. This can result in an undesirable change in the burning properties.
• the connection of the detonating cord to the firework article can be caused by shocks e.g. are loosened during transport or by the vibrations caused by the ignition of the other fireworks items in the same packaging.
• unexpected ignition difficulties can occur when the fuse branches.
• the object of the present invention is to provide an ignition device for fireworks articles with which a safe and exact ignition or ignition sequence is ensured.
• the ignition device should advantageously be able to be used for a plurality of firework items which are arranged in a packaging designed as a firing device, and should be designed in such a way that it can be used universally for a modular and thus flexible production of a plurality of products.
• the manufacturing costs be significantly reduced and the manufacturing time can be shortened.
• an ignition strip which has a receiving channel for an ignition means, for. B. has a delay charge, and at least one of the receiving channel branching ignition channel, which leads to the ignition charge of a firework item.
• the ignition channels are preferably received in necks projecting from the receiving channel, which are filled with a pre-ignition charge and onto which the firework items are attached.
• the fireworks have z. B. on its bottom a recess or a sleeve, at the end of which the primer for the active charge of the firework article is arranged. A neck of the ignition bar and a recess or sleeve of the firework article thus act together like a plug and socket.
• a compact ignition strip is created, which enables safe and exact ignition of fireworks items without a fuse.
• the firing bar can also be used to ignite several firework items in an exact chronological order, which are contained in a packaging designed as a firing device.
• the ignition strip can also be produced in various lengths in a simple and cost-effective manner, so that it can be used flexibly for the ignition of several and also different firework items.
• the ignition bar is against moisture or insensitive to temperature and impact and can also be stored well.

• Fig. 5 is a sectional view of the arrangement of the ignition bar and the fireworks in a package according to a second embodiment of the invention.
• Fig. 6 is a sectional view of another embodiment of an ignition bar according to the invention.
• an ignition strip 1 contains a tube 2 with a receiving channel 3 for a delay set 4 or an ignition cord 4 '.
• the tube 2 is flat Carrier strip 5 covered and fixed by clips 6 of the carrier strip 5.
• the carrier strip carries a plurality of sleeve-shaped necks 7 projecting from the tube 2, each of which has an ignition channel 9 filled with an ignition charge 8.
• the ignition channels 9 are each connected to the receiving channel 3 by a branch channel 10 through the support bar 5 and the tube 2.
• a fireworks article in this case a fire pot 11, can be placed on each neck 7, which for this purpose has a recess 12 on its bottom with a clear width corresponding to the outer diameter of the necks. At the bottom of the recess 12 there is an ignition charge 13 for the active charging of the fire pot.
• the delay charge 4 is ignited at one end of the ignition bar 1, the delay charge glows and burns slowly in the direction of the first neck 7. As soon as the embers reach the first branch channel 10, the lighting charge 8 is ignited, which burns up quickly and almost explosively. The ignition charge of the fire pot is ignited by the fire jet of this charge, which in turn ignites the effect charge. The delay charge continues to burn towards the second neck, where the process described is repeated.
• the ignition bar 1 can be connected to the firework items to be ignited immediately before firing, for which purpose the ignition bar can also be designed to be correspondingly flexible.
• FIG. 3 it is advantageously used in connection with a packaging for the firework items, here again fire pots 11, which serves as a launching device.
• the ignition strip is already connected to all the fireworks items in the packaging, so that after the packaging has been reshaped accordingly, it becomes Firing device can be fired in succession after lighting the ignition bar.
• FIG. 3 only one cuboid lower part 14 of the packaging is shown, which serves as a firing device for the fire pots 11, but not the cover to be put over it.
