Description

Device for the supply of liquids for human consumption or other uses.

The present invention patent application it consists, as indicated in its statement, in a "device for the supply of liquids for human consumption or other uses " whose new construction features conformation and design fulfills the mission for which it has been specifically designed with maximum safety and efficiency, and presenting numerous advantages as will be detailed hereafter.

More specifically, the invention relates to a dispenser properly designed to supply liquids for human consumption or other uses once cooled from a part of the volume of the bag that acts as a deposit. The device of the present invention uses as means of liquid cooling contained a peltier system duly adapted acting on a reduced volume of said bag.

The object of the invention is the result of a extensive market research conducted in the USA and the EEC on a series of four hundred dispensers. The study was conducted with independence of the material in which these were manufactured dispensers (glass, PET, PC, or similar materials). These dispensers were installed and working, and they presented different technological conceptions and characteristics each.

The invention contributes to the state of the art formed by these devices a totally new dispenser in its main parts, presenting a manufacturing cost and lower maintenance than those studied, as will be discussed more ahead.

The research project on which based the object of the invention has placed its emphasis on improving, among other aspects, the internal hygiene of the dispenser as its functioning. In addition, it brings a set of quantifiable technical advantages of a practical nature, such as It will look like this.

To cool the liquid contained in the Deposits of prior art dispensers were necessary A cold equipment with many refrigerators. This was a cost high performance, which is why he went to his day intermediate solutions such as cooling by means of a coil refrigerated a partial volume in a separate tank from the main one. This implied that, although the economic aspect of dispensers that are part of the technique were resolved so satisfactory, as far as the cooling capacity is concerned, the hygiene in this technological solution was not adequate as consequence of the bacterial contamination that occurred in the coil used to cool said volume partial.

Additionally, it was observed that another point of contamination occurred in the replacement operation of the main storage tanks for the liquid to cool. When they run out, they are held by the mouth or tap to take them to a filling station and reinstall them in The place of origin. This is done without changing the deposit or the tap, unless they present some type of breakage.

Pollution can also occur on its own  tap installed in the tank, since it does not change in the existing dispensers even if the main deposit is filled. In this sense, maintenance and cleaning are not taken to the practice in 90% of the cases studied, either by a inadequate sanitation or involuntary negligence. Another type of possible contamination is due to the entry of ambient air and its mixture with the liquid during its consumption.

From the economic side, the cost of operation of the return operation of empty containers for cleaning and sanitation proved expensive and complex, due use a machine with a high investment for the sake of achieve productivity in line with that investment. It is necessary also an adequate logistics for the transport of the containers gaps to the filling station and its return to the points of origin.

The results of this study have indicated that the points on which action must be taken to improve Dispensers that exist in the market are the following:

- Liquid storage tank a cool.

- Liquid cooling system a Supply by dispenser.

- Tap installed in the tank to dispense the liquid already cooled.

- Nature of the users.

- Prevent the entry of ambient air into the liquid reservoir

The disadvantages found in the study made of state liquid supply devices of the technique are, among others, the need to refill the deposit, which requires transportation from the location of the device at the user's address to the place where Find the tank filling and cleaning plant and a subsequent transfer of them already full to the place where They are installed. This negatively influences a loss of time and money in said refilling operation, since the magnitude of the space necessary for the transfer of the deposit in the  means of transport corresponds to its volume. On the journey outbound for filling, the deposits are completely empty and it is not possible to modify the volume of these deposits so that in the means of transport can be carried more in a single trip. This does not it is possible with conventional supply devices since the tanks are manufactured rigid, occupying the same space as in the return trip, in which said deposits are filled with liquid.

Additionally, the refill operation It involves health problems, since there is a major risk of contamination even if precautions are taken necessary. To all of the above, keep in mind that the tap installed at the source, as long as it remains in good condition of operation, it is never replaced. Therefore, sanitation it is not properly controlled, nor is its contamination fruit of improper use, although in the recommendations of the manufacturer the source user is invited to a cleaning of the aforementioned tap. However, this operation is not carried out. carried out satisfactorily.

In this regard, the present invention proposes a  new device for the supply of liquids for consumption human or other uses of new conception, which includes essentially a reservoir containing a liquid, means of cooling of the liquid contained in said tank and a tap for the regulated exit of said liquid to the outside forming all It is a unit.

The particularity of the device of the invention  resides in the fact that said deposit is a bag disposable and single use, which incorporates said tap, being the aforementioned bag housed inside a bucket manufactured in rigid plastic or similar material.

Therefore, the deposit, which is part of the new dispenser of the invention has been totally modified being functionally and formally new, not only in its configuration but, instead of being refillable, it is a single use and has a lower weight. This design incorporates the means to allow its transfer and installation with full guarantee of hygiene and ease for the user, manufactured with equipment designed for a production capacity of 3,600 bags / hour, which can be doubled with the same equipment, and incorporating a faucet, so the cost of it is much lower in comparison with those already existing in the state of the art, respecting the total asepsis of the operation when used laminar flow techniques to condition an overpressure on the environment to prevent the entry of germs and others.

The manufacturing materials of the bag are mainly a six-layer coextruded film manufactured from thermoplastic materials. The inner layer that is in contact with the liquid is polyethylene or PET, using sanitary materials approved for this purpose by all administrations that take care of products for human consumption.

As indicated, the deposit is incorporated a tap, also for single use as well as the tank, all This without detriment to its quality and hygiene, manufactured from corresponding mold using material injection techniques thermoplastics As will be described herein with greater detail below, the main feature of the tap that equips the liquid dispenser object of the present invention is that it consists of two unique pieces, allowing the filling the bag once said tap is incorporated in it An exceptionally short time.

According to the invention, said bag is  equipped with an intermediate welding line that delimits the bag in an upper zone and a lower zone of different volumes. The said upper zone is of greater volume than the lower zone and This area incorporates the tap mentioned above.

According to another feature of the device of the invention, the refrigerator that houses the bag (one or more) has a front cover that allows access to the inside of the device to handle bags comfortably. The lid is articulated and it has an internal projection that is aligned, in the position of closure, with an opposite projection of the inner wall of the cuvette of the fridge among which is the bag. In that position of closing, the internal projections delimit the bag in an area upper and lower zone of different volumes, reducing the communication between the two volumes, as an alternative solution to the one described in the previous paragraph.

The lower part of the refrigerator houses a bucket of aluminum or similar material, whose shape and dimensions are according to the configuration of the bag to obtain the maximum contact surface between the bag and said bucket.

In one embodiment, said refrigerator incorporates, instead of a tap, a selector mechanism for the supply of water from different bags. This selector mechanism is mounted on a flip platform so that it can be hidden easily and acts on two groups of tubes that meet connected, respectively, to the lower zone and the zone top of the bag to get liquid at the temperature adequate. The selector mechanism is formed by straps that they act on each tube imprisoning it.

Once the final design of the bucket, bag and tap, there are some means of refrigeration inside the refrigerator, so that the set formed by the bag, the tap and the refrigerator form a Unit.
