  • the opening 14 has an internal thread, for example on, into which a corresponding external thread of the cover 16 can be screwed.
  • a cooling tank 18 is arranged inside the container body 12.
  • the cooling tank 18 contains a liquid gas 20, such as, for example, a liquid nitrogen oxide (N 2 O) which is food-compatible, ie food-grade, in particular non-toxic.
  • N 2 O liquid nitrogen oxide
  • other liquid gases can of course also be used, provided that they are also food-compatible if the liquid container 10 is used for drinks.
  • liquefied gas is understood to mean a substance which is in the gaseous state at room temperature under normal pressure, ie whose boiling temperature is significantly below room temperature, and which has been brought into its liquid phase by appropriate excess pressure.
  • the cooling tank 18 is filled in a vacuum, for example under a pressure of approximately 4 bar, with the liquid N 2 O by means of a suitable device via an opening 22 in the upper section of the cooling tank 18.
  • the opening 22 of the cooling tank 18 is then closed liquid-tight with a corresponding closure 24.
  • the closure 24 has a downwardly projecting, that is to say arranged on the side facing the cooling tank 18, first threaded section 26, which can be screwed into a corresponding thread at the upper end of the cooling tank 18.
  • the closure 24 is provided on the side facing away from the cooling tank 18 with a second threaded section 28, into which an opening device to be described later can be screwed.
  • the closure 24 of the cooling tank 18 is preferred for reasons explained later Made of plastic.
  • the cooling tank 18 itself preferably consists of a heat-conducting one Plastic material to ensure good thermal contact with the inside of the To ensure the container body 12 of the liquid container 10.
  • the cooling tank 18 must also be constructed to withstand the pressure of the liquid gas 20 therein.
  • the cooling tank 18 After the cooling tank 18 has been filled and closed, it is placed in the container body 12 of the liquid container 10 used.
  • the cooling tank 18 is preferred positioned centrally in the container body 12 and firmly with this in the base area connected.
  • the container body 12 has webs 30 with latching lugs in the base region 32, which in a corresponding recess 34, for example in the form of a groove on the Intervene on the outside of the cooling tank 18.
  • the webs 30 and the recess 34 are there preferably formed all around the circumference.
  • the Web 30 with the detents 32 preferably with the lower portion of the cooling tank 18th welded using heat (e.g. hot air). This is possible because the container body is made of a plastic material.
  • the cover 16 has a first threaded section 38 on, which can be screwed into the thread of the opening 14. Further has the lid 16 following the first threaded portion 38 on the Cooling tank 18 side facing a second threaded portion 40, which so is designed such that it fits into the second threaded section 28 of the closure 24 of the Cooling tanks 18 can be screwed.
  • the second threaded section has 40 of the cover 16 has a smaller cross-sectional dimension than the first threaded section 38th
  • a tip 42 is provided on the side facing the cooling tank 18, initially in the position shown in FIG illustrated first closed position of the cover 16 on the first threaded portion 26, which closes the opening 22 of the cooling tank 18, stands up.
  • a gas channel 48 which is the front End of the tip 42 connects to the surroundings of the liquid container 10, as in Figure 2 shown.
  • both the first and the second Threaded section 38, 40 of the cover 16 even further into the corresponding threaded sections the container body 12 or the closure 24 of the cooling tank 18 screwed become.
  • This first closed position of the cover 16 is due to the on the first threaded section 26 of the closure 24 of the cooling tank 18 tip 42 of the lid 16 is defined and is fixed by on the outside of the container body 12 Web 44, which are fixedly connected to the lid 16, secured. Fixing this Crosspieces 44 on the container body 12 are made, for example, by means of a plastic seal 46, which tears open relative to the container body 12 when the lid 16 is rotated.
  • the liquid container 10 shown in Figure 2 is now, i.e. with the filled in Liquid 36 and the lid 16 in its first closed position, ready for operation. Based on this, the liquid 36 can now be cooled in the liquid container 12 are, as explained below with reference to Figure 3.
  • the lid 16 is broken by breaking the plastic seal 46 of the webs 42 on the container body 12 further into its second closed position screwed, as indicated by an arrow 50.
  • the first turns Threaded portion 38 of the lid 16 further into the thread of the opening 14 of the container body 12 and the second threaded portion 40 of the lid 16 further into the second Threaded section 28 of the closure 24 of the cooling tank 18, so that the tip 42 of the Lid 16 pierces or pierces the closure 24 of the cooling tank 18, as in FIG 3 shown.
  • the gas channel 48 which runs through the entire cover 16 creates thus a gas connection between the inside of the cooling tank 18 and the surroundings of the Liquid container 10.
  • the container body 12 remains in the second closed position the lid 16 is still closed liquid-tight.
  • This gas connection allows the liquid gas 20 to evaporate in the cooling tank 18, such as indicated at 52, 54 in Figure 3.
  • the one required for this evaporation process Evaporation heat draws the liquefied gas 20 from its surroundings, i.e. on the thermal contact with the inside of the container body 12 from the liquid 36 in Container body 12, whereby this liquid 36 is cooled.
  • the degree of cooling of the liquid 36 in this process depends on the amount of the liquid gas 20, the heat of vaporization of the liquid gas 20 (for example about 377 kJ / kg for N 2 O), the amount of the liquid 36 to be cooled (for example water) and the thermal conductivity of the material of the cooling tank 18.
  • the liquid gas 20 evaporates, for example, from the cooling tank 18 within about two minutes, and only about 150 ml of N 2 are produced for cooling about 330 ml of water as the liquid 36 to be cooled by 20 ° C. O needed as LPG 20. If necessary, the liquid 36 can even be frozen.
  • the container body is preferably made of a thermally insulating plastic material.
  • the Lid 16 simply completely unscrewed from the container body 12, as in Figure 4 shown.
  • the closure 24 of the cooling tank 18 also becomes unscrewed. This is possible if, for example, the second threaded section 26 of the Closure 24 is a left hand thread, and the first and second threaded portions 38, 40 of the cover 16 are each a right-hand thread. Unscrewing the closure 24 reduces the risk of injury to the user.
  • the container body 12 has outside in the bottom area additionally a paragraph 56.
  • the inverted cover 16 can be placed on this shoulder 56 after opening the liquid container 10 are advantageously plugged on, when the liquid 36 is poured from the container body 12.
  • the lid 16 can also be screwed onto the container body 12 again, if all of the liquid 36 has not been removed.
  • the cooling tank does not necessarily have to be arranged centrally in the container body. It is even conceivable to arrange the cooling tank outside the container body around its circumference. Furthermore, the present invention is not limited solely to N 2 O as liquid gas for the cooling tank.
  • All materials of the container body, the lid, the cooling tank and the Closure are preferably recyclable plastic materials.
