Definitions

  • the invention relates to an explosion-proof bottle spout for flammable liquids or pastes.
  • Explosive fuel-air mixtures can form in bottles that are used to store flammable liquids or pastes after partial emptying. If they reach the area of an open flame, they can ignite and cause an explosion inside the bottle, which can have serious consequences.
  • the document DE-U-9004674 discloses an explosion-proof bottle spout for flammable liquids or pastes, as well as a suitable squeeze bottle made of plastic, the flashback or spark back into the bottle inside being avoided by means of a check valve.
  • the object of the invention is to provide a simple, safe-acting, explosion-proof bottle spout that can be mass-produced and has no moving parts and that can be connected to conventional bottles, in particular squeeze bottles.
  • the mode of action is based on the fact that an explosion of an explosive mixture can only take place when the ignition temperature is reached. At a temperature below this mixture-specific ignition temperature there can be no explosion. Since the pouring spout has a narrow, elongated gap, there is no flashback or spark back into the bottle interior, because the narrowed point causes a flame or spark to cool below the explosion temperature and therefore no explosion can take place, even though an ignitable mixture is present.
  • gap is also to be understood to mean a straight or otherwise shaped slot shape.
  • the flammable liquid or paste can thus be pressed out by pressure on the bottle wall of the squeeze bottle, whereby it flows through the gap 2 and then exits through the pouring opening 5. Even if an explosive mixture should emerge from the bottle and get into the area of a pilot flame or a spark, it is not possible for a spark to flash back into the bottle at normal ambient temperature, since cooling takes place in the narrow gap 2, which extinguishes the Flame leads.
  • the narrow gap 2 together with its relatively large length, results in a large cooling surface which prevents the ignition temperature behind the gap 2 from being reached.
