Definitions

  • the invention relates to a method for producing a container for the removal of liquids, in particular water, consisting of an outer container and an inner bag for use in a liquid dispenser, further comprising a liquid container, in particular a water container and a bag therein, as a drinking water dispenser with reduced Nucleation can be used.
  • a water dispenser (also called water cooler) is a soft drink machine understood that (usually free of charge) gives off water and to hold appropriate small cups.
  • Water dispensers are found mainly in companies and medical practices, increasingly as a service in department stores or supermarkets. They are available as table-top units, which can be used in tea kitchens, for example, as they are usually only slightly larger than a coffee machine, and as pedestals, whereby a distinction is made here between table-top units with a base cupboard and appliances in stainless steel pillars. You can choose from mostly still (ie without carbonic acid) uncooled, still cooled and carbonated water. There are cable-bound and non-wired water dispensers. The piped systems are connected to the water pipe, the water is removed via a simple button system.
  • Unconductive systems typically use spring water or reverse osmosis water from large containers. Reverse osmosis water achieves good analytical results, but also loses all the characteristics of spring water, especially in terms of vital mineral content and natural taste. As with all equipment that comes in contact with food, regular cleaning is necessary because the problem of microbial contamination is omnipresent. There are, for example, extra directives such as the EBWA (European Bottled Water Association), GBWA (German Bottled Water Association) or the NSF (National Sanitation Foundation), which provide a cleaning of the water dispenser. Recommended, for example, the taps and drip pans daily with special Clean cleaning cloths and / or hygiene spray. Larger companies offer maintenance services that meet the hygiene guidelines of the associations (at least twice a year, replacement of all water-contacting parts and pipes).
  • the guidelines for cleaning a water dispenser thus only provide for the cleaning of the mechanical parts of the water dispenser; However, they do not solve the problem of a possible contamination of the water itself. A possible contamination leads to a lack of acceptance of the water dispenser on the part of the consumer. Because the containers filled with water are supplied by suppliers and are often filled for a long time and unused, installed on the water dispenser. This inevitably leads to a more or less strong - depending on the frequency of water withdrawal and thus consumption of water - contamination of the water.
  • wine hoses For other beverages, such as wine, it has been customary for some time to use so-called wine hoses.
  • a wine hose elastic containers are called, in which wine is traded and from which wine is tapped.
  • Such wine hoses are usually made of plastic or aluminum foil. Often they are surrounded by a more or less decorative cardboard and have a dispensing device. Common sizes are 3 and 5 liters and are also called cubitainers in French.
  • the international / technological name is Bag-In-Box.
  • the dispensing device is designed so that although the wine leaves the hose, but it does not penetrate air.
  • the tube is gradually evacuated, similar to a toothpaste tube that is expressed, without the wine remaining in the tube being able to oxidize. Thanks to the design of the tap, no oxygen can get inside, and the hose collapses more and more due to the vacuum at each tap. Therefore, it is possible to store or use the opened tube for up to a few months without the quality of the wine being lost.
  • DE 196 26 967 C2 From the prior art ( DE 196 26 967 C2 ), although a method is known to produce a container having a rigid outer container and an easily deformable inner bag.
  • the DE 196 26 967 C2 does not, however, provide a solution to the above problem - water storage without nucleation from water containers, but deals solely with the introduction of a bag into a substantially rigid outer container.
  • Object of the present invention is therefore to provide a water dispenser of the type described, which is inexpensive to manufacture in which the water supply in the water bottle has only a low bacterial load.
  • This embodiment is advantageous over the prior art, since when removing the liquid no air enters the bag.
  • liquids preferably water can be removed with drinking water quality, regardless of the germ load of the environment. Therefore, the container is also suitable for an irregular removal of liquids, as a longer storage time does not lead to increased germ load of the liquid.
  • the microbiological quality of the extracted water thus always complies with the German Drinking Water Ordinance 2001.
  • a bag is guided into the outer container and then filled with a liquid, preferably water.
  • the outer container itself is provided with at least one, preferably two, particularly preferably three, air openings.
  • an outer container with an air opening in the region of the bottle bottom and two air openings in the upper part of the outer container facing the bottleneck has proven.
  • the bag can be filled quickly, without building up a high pressure in the outer container.
  • the removal of liquid is facilitated.
  • this method is best suited to make an outer container with pressure equalization holes.
  • one or more holes are inserted into the outer container without the remaining material losing stability. Simple drilling or punching often causes small cracks, making the outer container brittle or porous.
  • PET preform a preform which is blown from a preform (called PET preform) and not extruded.
  • the method is preferred, wherein the pouch of a thermoplastic material preferably consists of PET (polyethylene terephthalate). Further preferably, the bag comprises at least one or more layers of plastic. As a result, a particularly stable and tear-resistant bag is obtained.
  • This embodiment is preferred because it is inexpensive, stable, non-toxic and recyclable material. It is also advantageous that this material does not change the taste of the liquid, especially water.
  • the bag itself complies in its nature all food quality standards. These properties are advantageous for use in polycarbonate reusable containers. Since the polycarbonate bottle no longer comes into contact with drinking water, it can not release any substances to the water. This embodiment is therefore particularly suitable for countries in which polycarbonate bottles are used, which flooding the substance of bisphenol A, which is considered to be harmful to health. Even with the use of such bottles, bisphenol A can no longer enter the drinking water since the bag sufficiently protects the water.
  • the complex cleaning of returnable bottles can be bypassed or simplified by the invention. Since the water does not come into contact with the outer container, it can be used several times without having to be cleaned. By replacing the bag, the cleanliness of the water is guaranteed at all times. A cleaning of the outer container can therefore be done at greater intervals. The cleaning itself can be carried out cost-effective and time-saving, since the requirements for an outer container are not as high as a returnable bottle which comes into direct contact with the drinking liquid.
  • the cut of the pouch forms a dense and impermeable unit with the bottle neck and cap of the gallon bottle after closure.
  • the closure device is a closure securing ring, whereby a particularly reliable closure is ensured.
  • the sterile foil of the closure device is a thermoplastic foil. This film ensures that no dirt and germs get into the bag before filling. The film is only immediately pierced before filling so that the bag remains airtight up to this point.
  • the liquid container consists of a solid PET outer container and / or an inner bag made of thermoplastic material.
  • An outer container made of PET is preferable because it is a cheap and stable material. Thus, an outer container can be used several times without losing stability.
  • the liquid container comprises a container opening and at least one, preferably two, wall openings are located in the outer container, through which a pressure equalization takes place in the region between the inner bag and the outer container.
  • the liquid container is preferably a gallon bottle.
  • the 5 gallon bottle is the most commonly used water bottle. This embodiment is therefore preferred since it can thus be used for many standardized liquid dispensers.
  • liquid container wherein the bag at the upper end by means of a closure device with integrated guide tube and sterile foil is airtight sealable and the closure device comes to rest during insertion of the bag in the outer container fit on the opening of the outer container.
  • the bottleneck provides a double and airtight connection to the closure cap. Therefore, preferably not only a leak-proofing device is used, but a second locking device is inserted.
  • the liquid container which has an additional seal at the bottleneck between the bag and the liquid container. Due to the additional seal no air can get into the bag even with very long bearings. Thus, the liquid remains drinkable longer, without dirt or germs can accumulate.
  • This seal supports the impermeable unit formed by the gallon bottle's pouch, bottleneck and cap after sealing.
  • the liquid is preferably water.
  • Water is particularly suitable because it contains no substances that can justify an expiration date. If no germs get into the bag, the water can be stored indefinitely without losing the quality of the drinking water.
  • liquid container is system-connected to a liquid dispenser corresponding to the liquid container.
  • the invention relates to a bag, for use in a liquid container, in particular a water container, as part of a liquid dispenser, in particular a water dispenser, which contains additional welds for sealing and the clean storage of liquids, especially water is used.
  • the bag is preferably made of a thermoplastic, preferably PET (polyethylene terephthalate). Furthermore, the bag preferably comprises at least one or more layers of plastic.
  • This embodiment is advantageous because it is inexpensive, stable, non-toxic and recyclable material which has no influence on the taste of the liquid.
  • the bag itself complies in its nature all food quality standards.
  • This pouch connector can use air to aspirate and aspirate the pouch and, at the top of the bottle, fold the pouch over the neck of the pouch so that the pouch can seal both units.
  • the invention relates to a liquid dispenser, in particular water dispenser, comprising at least one dispensing device, and a liquid container serving as a liquid reservoir, in particular water reservoir, in particular water container, in particular in the form of a gallon bottle.
  • the invention relates to a kit comprising a bag and a closure device with integrated guide tube and a sterile foil and optionally information for using the individual components.
  • At least two pressure equalization openings are incorporated to the outside.
  • the outward pressure equalization openings are pierced from the outside, for example pierced, cut or punched.
  • a bag of thermoplastic material preferably PET
  • a closure device preferably a closure securing ring, with integrated guide tube, which leads into the outer container and thus is located inside the inner bag.
  • the closure locking ring with integrated guide tube closes the bag, namely preferably by gluing or welding.
  • a thermoplastic film is arranged as a sterile foil, which seals the bag airtight.
  • the lock securing ring fits snugly on the opening of the outer container and seals it as it were.
  • the filler of a filling device pierces, cuts or punctures the thermoplastic foil (sterile foil) of the closure securing ring which is mounted in the middle.
  • the closure securing ring is closed, namely preferably by a plastic cap (squeeze screw or pressure lock), so that it is firmly closed to the container.
