Definitions

  • the invention relates to a heat insulation container for beverage containers, in particular for beverage cans.
  • Thermal insulation containers for beverage containers have been known for a long time.
  • a holder for cans for motor vehicles is known, the outer jacket being made of polystyrene.
  • Another heat insulation container with an inner lining made of heat-insulating plastic material is known from DE-GM 77 22 222, in which a heavy floor is provided which is suitable for being placed in a motor vehicle.
  • both heat insulation containers are comparatively complex products, which are already unsuitable as inexpensive, reusable advertising media in terms of production costs.
  • these heat insulation containers cannot be optimally handled together with the beverage container, for example with a beverage can.
  • these conventional heat insulation containers are not flexible and a beverage container cannot be accommodated in them so that the beverage container adheres to the heat insulation container by itself, but can still be detached from the beverage container so that it can be reused for environmental reasons and for reasons of cost savings is.
  • the invention has for its object to provide a heat insulation container of the type mentioned, which is easy to handle together with the beverage container, can also serve as an inexpensive advertising medium at low manufacturing costs, and Heat insulation container is reusable and can be disposed of in an environmentally friendly manner.
  • the heat insulation container consists of a circular-cylindrical wall part provided with an inner wall, which is closed at one end by means of a circular disk-shaped base part, at least the base part and / or the wall part located near the base part being air-permeable, the heat insulation container is made from foamed polyethylene (PE) and / or from foamed polypropylene (PP) and the inner wall is coated with a thin layer of talc.
  • PE polyethylene
  • PP foamed polypropylene
  • the materials polyethylene and polypropylene offer the advantage that they are flexible and therefore adapt well to a beverage container such as a bottle or a can. This provides particularly good thermal insulation.
  • the heat insulation container has a very low weight and is therefore easy to handle together with the beverage can because the aforementioned plastic can be gripped non-slip.
  • Polyethylene as from polypropylene, can be burned without polluting the environment and is generally considered to be harmless to health. Another important environmental aspect is to make the heat insulation container reusable. Since for good heat insulation with simultaneous good handling of the heat insulation container, the latter must lie so close to the beverage container that the beverage container is clamped, it is easier for the beverage container to be pushed into the heat insulation container and for the beverage container to be pulled out of the heat insulation container without damage of the heat insulation container, the talc layer according to the invention is attached to the inner wall of the heat insulation container.
  • the main area of application of the heat insulation container according to the invention is to keep beverages in beverage containers cool. Bottles and especially cans come into consideration as beverage containers. However, it is also possible to use the heat insulation container according to the invention for keeping warm beverages warm, for example for tea or coffee located in cups. This offers the additional advantage that even a thin-walled cup, which is otherwise uncomfortable to hold due to the high heat of the beverages, is easy to handle by means of the heat insulation container according to the invention.
  • the talc layer is applied to the inner wall by dusting powdered talc, which can be done with the aid of an atomizer.
  • Commercial talcum powder can be used for this.
  • Talc is generally understood to mean hydrated magnesium silicate with the composition Mg3 [(OH) 2 / Si4O10] or 3MgO ⁇ 4SiO2 ⁇ H2O.
  • the foaming is carried out by a chemical blowing process by gas-decomposing decomposition of synthetic yeast as a chemical blowing agent.
  • environmentally friendly foaming can be achieved without the development of CFCs.
  • Another CFC-free foaming can advantageously be carried out by a known high-pressure process with nitrogen or CO2, these gases being dissolved in the melt of thermoplastics under a pressure of about 200 bar and later foam in a known manner, for example by relaxing in the manufacture of a tube, in an extruder.
  • the air permeability of the base part or the wall part close to the base part enables the beverage container to be pushed effortlessly into the heat insulation container, since the air can escape and so when the beverage container is pushed in, no air cushion is formed from pressurized air, which makes it difficult to push the beverage container in or out no negative pressure is built up when pulling out the beverage container, which complicates this process.
  • the foamed polyethylene (PE) or the foamed polypropylene (PP) can be closed-cell. Closed-cell, foamed plastic offers the advantage of better thermal insulation compared to open-cell, foamed plastic.
  • the bottom part (4) can essentially consist of open-celled, flexible, foamed polyethylene (PE) or polypropylene (PP), which makes it permeable to air.
  • the base part has at least one through hole.
  • a hole can be provided in the middle of the bottom part.
  • the inside diameter of the wall part is dimensioned such that a standardized beverage container can be inserted into the wall part as far as the bottom part and the outer peripheral surface of the beverage container lies so closely against a cylindrical inner wall of the wall part that a beverage container inserted into the heat insulation container can be detached from it on its own Heat insulation container adheres, the inner diameter of the cylindrical wall part corresponding to the outer diameter of 65 mm of standard beverage cans, the wall thickness of the wall part being 10 mm and the height of the heat insulation container being 100 mm.
  • the beverage container cannot fall out of the heat insulation container or the heat insulation container cannot fall off the beverage container. Due to the flexibility of the polyethylene or polypropylene of the heat insulation container, the beverage container is held in the manner of a slightly tensioned rubber sleeve, but can still be removed due to the talc coating.
  • the aforementioned, common, standardized beverage can has a capacity of 0.33 l.
  • the heat insulation container according to the invention with correspondingly different dimensions can also be used for standardized 0.5 liter cans as well as for any standardized beverage bottles, for example 0.7 liter bottles.
  • the wall part is a cut-to-length piece of a prefabricated tube made of polyethylene or polypropylene and the bottom part is a circular disk cut or punched out of a prefabricated sheet of foamed polyethylene or polypropylene, which is at one end of the wall part in this is welded or glued.
  • the aforementioned high-pressure foaming process is particularly suitable for manufacturing.
  • the heat insulation container is produced in one piece by foaming a mold.
  • the above-mentioned chemical foaming process with synthetic yeast as blowing agent is special advantageous.
  • An outer wall surface of the wall part is advantageously suitable for printing an imprint or gluing or welding on a thin-walled plastic part.
  • the outer surface should have a reasonably smooth surface made of the plastic.
  • Advertising prints can be printed on such a surface, or advertising lettering made from colored foil can be welded or glued on.
  • an aluminum coating is provided on the outer and / or inner surface of the heat insulation container. This offers even better thermal insulation with a low weight, since the radiation energy of the sun is reflected.
  • FIG. 1 shows the heat insulation container 1, in which a beverage container 2 in the form of a standardized beverage can is inserted.
  • the heat insulation container 1 is shown in a sectional view, while the beverage container 2 used therein is shown in a side view.
  • the heat insulation container 1 has a wall part 3 and a bottom part 4.
  • the bottom part 4 is welded or glued into the wall part 3 around an annular surface 5 at one end.
  • the bottom part 4 is a circular cylindrical plate which is made of polyethylene or polypropylene.
  • the wall part 3 represents a cut piece of a prefabricated pipe from the foamed plastic, which is commercially available.
  • the annular surface 5 is omitted and the base part 4 is connected in one piece to the wall part 3. This can be achieved, for example, by foaming a mold.
  • a through hole 6 is provided in the middle of the bottom part 4 so that the bottom part 4 is permeable to air in order to facilitate the pushing in and taking out of the beverage container 2 from the heat insulation container 1.
  • the cylindrical inner wall 7 of the wall part 3 lies tightly against an outer circumferential surface 8 of the beverage container 1 and thus clasps the beverage container 2 in the manner of a slightly tensioned rubber sleeve.
  • the inner wall 7 of the heat insulation container 1 is provided with a thin talcum layer. This can be generated, for example, by simple dusting, but also by rubbing in talc.
  • the cylindrical inner wall 7 is relatively smooth in addition to the coating with talc.
  • a cylindrical outer wall 9 of the heat insulation container is relatively smooth, so that an imprint can be applied without problems or as a thin-walled, colored film part 10 can be welded on or glued on after a possible pretreatment of the outer wall 9, the film, for example, the contour of an advertising lettering may have.
