Fireworks are actually similar in structure to firecrackers, and both of them contain black powder and medicine. In order to achieve good performance, fireworks and fireworks bombs are filled with a lot of gunpowder for launching and explosion. For example, a fireworks bomb with a diameter of 2 cm will not explode until it rises to an altitude of about 2 meters after launching, and the radius covered by these dots can be about 8 meters.
Category of fireworks trademarks: Fireworks trademarks belong to the 13th category in international classification, and fireworks, signal fireworks, pyrotechnic products, explosive smoke signals, firecrackers, firecrackers, fireworks, firearms, arms, bullets, explosives and other related arms and pyrotechnic products all belong to this category.
according to the trademark classification query tool, fireworks trademark registration belongs to the 133 group of the 13th category of trademarks. According to the 219 Nice Classification Table, the 13th category of trademarks is mainly firearms; Arms and ammunition; Explosives; Fireworks.
enterprises want to register fireworks trademarks, but they don't know what category their registered fireworks trademarks belong to? The following small series will tell you in detail what classification category fireworks trademarks belong to.
Fireworks, also known as fireworks, fireworks and firecrackers, were invented earlier by working people in China and are often used in grand ceremonies or performances. The only event in modern China and the world where fireworks can be set off on the same day is regarded as New Year's Eve. Fireworks are actually similar in structure to firecrackers, and their structures all contain black powder and medicine. In order to achieve good performance, fireworks and fireworks bombs are filled with a lot of gunpowder for launching and explosion. For example, a fireworks bomb with a diameter of 2 cm will not explode until it rises to an altitude of about 2 meters after launching, and the radius covered by these dots can be about 8 meters.
In the process of making fireworks, some luminescent agents and chromophores are added to make fireworks emit colorful colors. The luminescent agent is powder of metallic magnesium or metallic aluminum. When these metals burn, they give off incandescent light. Chromophores are actually just some metal compounds. Metal compounds contain metal ions. When these metal ions react violently with oxygen molecules, you will see that the compound burns and emits a unique flame color. In order to protect the environment, many fireworks and firecrackers do not use substances containing heavy metals and sulfur elements, thus reducing the generation of sulfur dioxide and other sulfides. Secondly, the consumption of metal powder is reduced, and organic matter is basically used as combustible, thus reducing the inhalable particulate matter produced after the combustion of metal powder. The third is to change the oxygen balance and combustion temperature of the system and control the combustion reaction by changing the amount of oxidant and combustible.
Fireworks trademark registration belongs to the 13th category, Group 133. Let's first introduce the details of Group 133, hoping to help enterprises register their own product categories more accurately when registering trademarks.
