Definitions

  • the present invention relates to the field of liquid dispensing.
  • Water as a drink, is also very consumer of packaging.
  • water fountains are connected directly to the drinking water network, and users can use the faucet water refreshed or not, with a glass or reusable cup at will.
  • the present invention aims to overcome at least in part these disadvantages.
  • it proposes a method for making a liquid contained in a container available in homogeneous form, at a sampling means.
  • the liquid can be stirred, and thus its homogeneity can be maintained over time, without introduction of a part in the liquid, or even inside the container.
  • the hygiene of the liquid is improved until the time of sampling by the user.
  • the present invention also relates to a device for implementing a method according to the invention, comprising a support, for example a shelf, for containers of said liquid and a means for sampling at least a portion of said liquid.
  • This device is particular in that said container is flexible, so that said liquid can be removed without introducing air into said container, regardless of the amount of residual liquid in said container.
  • This arrangement is particularly interesting because it eliminates any intrusion into the container, whether a room to shake, or air to compensate for the volume extracted. The cleanliness of the liquid is thus easier to preserve.
  • a device 1 comprises a shelf 2 movable in rotation about an axis of rotation 3.
  • a holding box 4 with a lid 5.
  • Said box is secured to the shelf 2, and can be deposited there a flexible container 6 provided with an outlet valve 7.
  • This flexible container 6 contains a liquid, for example milk that wants to be available to customers in homogeneous form. That is to say, it is desired that the cream remains constantly mixed with the milk, and does not separate, so that by taking any quantity of liquid through the outlet valve 7, the liquid taken up is constituted substantially of the same composition as all of the liquid contained in the flexible container 6.
  • the axis of rotation 3 is shifted upwards relative to the shelf, which reduces the mechanical stresses of the of the mechanical transmission, from the engine to the axis of rotation itself, while allowing a smoother agitation of the liquid, without tendency to eject the liquid upwards, even with very short agitation cycles.
  • a flexible tube 8 conducts the liquid from the outlet valve 7 to a dispensing valve 9, where customers can come to collect any amount of homogeneous liquid.
  • the holding box can be directly attached to the axis of rotation 3, without shelf.
  • the cover can be a sliding cover with rails for example aluminum.
  • a handle can be used to lock the lid in the closed position and to unlock and slide open.
  • the Fig. 1 shows the shelf 2 inclined to the left upwards by an angle ⁇ , typically 60 ° with respect to the horizontal. In this position, the cream tends to move upwards, so towards the bottom of the flexible container 6. In the absence of homogenization, if we took the liquid with the flexible container 6 in this position, we would obtain after a few hours skimmed milk for the first customers, and cream for the last customers for this flexible container 6. This is of course not desired.
  • the Fig. 2 shows the shelf 2 inclined to the right upwards by an angle ⁇ , typically also 60 ° with respect to the horizontal. If the flexible container 6 remained stationary for several hours in this second position, we would obtain the opposite situation, where the first customers would get the cream, and the last of the skimmed milk.
  • the shelf 2 is alternately placed in the two positions of Fig. 1 and 2 , thus creating a stirring of the liquid, producing the maintenance of its homogeneity throughout the duration of the distribution.
  • Such agitation is obtained without intrusion into the liquid of any part, or even into the flexible container 6. The risk of contamination of the liquid by external impurities is therefore minimized.
  • the figure 3 shows the device 1 of the figure 1 at the moment when the flexible container 6 is almost empty.
  • the container 6 being flexible, its shape changes, and its volume narrows as it is emptied, so that it becomes unnecessary to provide an air inlet into the flexible container 6.
  • the liquid is perfectly isolated from the outside, the only communication with the outside being the liquid sampling, which is a one-way communication, only from the inside to the outside. outside.
  • the liquid sampling which is a one-way communication, only from the inside to the outside. outside.
  • the hygienic safety of the dispensed liquid is therefore very much improved.
  • the figure 4 shows a device 1 with three shelves 2.
  • One of the shelves 2 is rotated by an actuator 10, which is preferably an electric motor, controlled by a frequency converter, to make it perform movements back and forth in a desired form.
  • the actuator 10 could also be an electric cylinder or any other type of actuator.
  • the choice of the electric motor 10 associated with the frequency converter is due to the fact that it allows a wide variety of cycles, especially with very short cycle times.
  • Rods 11 connect the motorized shelf 2 to the other shelves 2, so as to drive them in a synchronous movement with the first shelf 2.
  • the rods 11 can be arranged so that the amplitude of the movement of all the shelves 2 is the even. But they can also be arranged so that one of the shelves 2 performs a synchronous movement, but with a different amplitude, especially if it contains a different liquid.
  • An offset plate 12 fixed on the side of the shelves 2 makes it possible to place the axis of rotation 3 close to the middle of the flexible container 6, and thus offset relative to the shelf 2.
  • Such an offset plate 12 makes it possible to choose freely the position of the axis of rotation 3, in order to optimize the stirring. This also makes it possible to avoid the tendency of the flexible container 6 to eject from the box during the rotational movements. This tendency is indeed all the less pronounced, that the axis of rotation 3 is closer to the center of gravity of the flexible container 6.
  • the set of three shelves 2 can be installed in a cabinet 13.
  • a cabinet 13 can contain several trains 14 of three shelves 2, each shelf 2 can support several holding boxes 4, for example 3 holding boxes 4 per shelf 2
  • the set of distribution valves 9 are arranged for example on the front face of the cabinet 13, so that the liquids can be taken without opening the cabinet 13. It is of course expected that several flexible containers 6 are connected to the same dispensing valve 9, when these flexible containers 6 contain the same liquid. Suitable devices, known to those skilled in the art, allow to move from one flexible container 6 to the other as soon as the first is empty, while ensuring the hygienic quality of the transfer.
  • the cabinet 13 may also contain other types of containers or dispensing devices.
  • the advantage of the present invention lies in the fact that liquids can be made available to users to be sampled in homogeneous form at any time, and this without requiring the slightest intrusion into said liquids, or stirring pieces, no air or other gas.
  • the present invention is more particularly applicable to food liquids, such as raw milk, UHT sterilized milk, whole, semi-skimmed or skimmed milk, yogurts of cream, cottage cheese, fresh or sterilized fruit juices, wines, honey, ...
  • food liquids such as raw milk, UHT sterilized milk, whole, semi-skimmed or skimmed milk, yogurts of cream, cottage cheese, fresh or sterilized fruit juices, wines, honey, ...
  • the invention can be applied to soups. A farmer can then recycle his second-choice vegetables, not salable in the form of soup, and sell it in this form for several more days.
  • Some supermarkets allow farmers to have a distribution cabinet near their entry or exit. A farmer can thus have a cabinet 13 containing a device 1 according to the invention, to provide customers with its various liquid products. It then suffices for it to come periodically to replace the empty flexible containers 6 by flexible containers 6 full. An empty bottle dispenser nearby can complete the offer for customers who have not brought their own containers.
  • the flexible containers 6 may typically be flexible bags with a capacity of 1 to 20 liters, depending on the liquid and the quantities dispensed per day.
  • the invention can also be applied to non-food products, such as wallpaper glues, liquid detergents, motor oil, or other liquids requiring agitation to remain homogeneous.
