Definitions

  • the invention relates to a fuel can, and the use of the fuel can as a heat and / or light source according to the preambles of the independent claims.

These fuel cans are inexpensive to manufacture and cause relatively little waste, but require a suitable burner for their intended use.
  • the fuel can which is provided as a disposable container for heating and / or lighting purposes, a cup or cup-like can body with a fuel filling and a closure lid which closes the can body tightly and is firmly connected thereto, which For example, by welding or gluing the closure lid to the can body, in particular by heat sealing the same to the can body, or by crimping can be achieved.
  • the closure lid has one or more predetermined separating points, to which one or more lid part elements are integrally connected, ie by integral formation, by gluing or by welding or soldering, with the remaining closure lid, such that a partial or complete Ab- and / or Separating this cover part elements by hand and without the use of tools from the rest of the closure lid or out of it is possible and thereby create one or more well-defined openings in the cap.
  • the planar extent of these openings is significantly smaller than the total surface of the closure lid or the surface of a fuel filling in the can body at medium filling level.
  • the predetermined separation points can be designed, for example, as areas weakened by punching or material removal or as adhesive surfaces.
  • the predetermined separation points are designed such that the one or more separable lid part elements are not completely separated from the lid after a complete separation of the predetermined separation points, but remain captive with this. As a result, all components of the fuel can stay together, which facilitates disposal and also opens the possibility to close the used fuel can at least temporarily again.
  • the closure lid is designed in such a way that at least part of the openings which can be produced by separating and / or separating lid part elements can be exposed by peeling off one or more lid part elements designed as peel-off foil elements, it being preferred if Exactly one such Abziehfolienelement extends continuously over the entire closure lid.
  • the Abziehfolienimplantation thus cover openings in underlying Cover parts and can be removed by releasing their adhesive bond with these cover parts, which represents the predetermined separation point, whereby the openings are released.
  • This construction offers the advantage that the detachable cover part elements can be made of a different material than the rest of the lid, which is hot in operation and therefore in the choice of materials leaves little choice, and that any problems in canceling the cohesive connection along the predetermined separating points has virtually no influence on the geometry of the opening to be exposed. It is also possible to use a multilayer film with a Abziehfoliendeck Mrs for the production of the closure lid and insert the desired openings already in all film layers except the Abziehfoliendeck harsh by punching, so that the punched parts are automatically removed when removing the Abziehfoliendeck Mrs from the openings.
  • the closure lid is designed such that at least a portion of the openings can be produced by separating out portions of the actual closure lid, so are formed integrally with the opening elements delimiting the opening to be generated prior to their separation.
  • the term "actual lid” here refers to the one or more components which remain after removing the detachable or detachable cover part elements on the can body and limit the openings. This has the advantage that the closure lid consists of a single-layer semifinished product, e.g. Foil or sheet, can be produced, which can be realized particularly simple and inexpensive cover.

  • cover part elements may be present, which can be separated or separated depending on the desired burning time and power or can remain untouched.
  • the closure lid of the inventive fuel can substantially consists of a foil or a sheet, in the latter case preferably made of aluminum sheet, since these materials are inexpensive as a semi-finished material available and can be processed with only a few and relatively simple processing steps to a novel closure cap.
  • the term "essentially” here means that at least the areas of the closure lid which remain on the can body after removal of the removable or detachable lid part elements are made of such a material.
  • closure cap consists of a sealing foil, which is preferably formed from several different layers of material, then it can be sealed by simple means on a flange edge of the can body, whereby a secure and tight connection between closure cap and can body can be produced.
  • a sealing film which, in addition to the sealing layer, has at least two metal foils, preferably made of aluminum, which are connected to each other in a planar manner by means of a plastic layer located between them, preferably of polyethylene.
  • a first of the two metal foils preferably the one which faces away from the can body, is weakened or interrupted along the predetermined separation point, while the other metal foil is formed continuously in the area of the predetermined separation point, then a lid with high strength and a reliably separable lid results predetermined breaking point.
