ITBL20070026A1 - BOTTLE WITH A CAP THAT ALLOWS TO MAINTAIN THE STATE OF EFFERVESCENCE AND INTEGRITY OF A LIQUID CONTAINED IN IT ALSO AFTER A PARTIAL CONSUMPTION OF THE LIQUID. - Google Patents

Abstract

The invention described here is a bottle for the holding of liquids consisting of two layers, one inside the other. The function of the inner layer (13) is to hold the liquid while that of the outer layer (12) is to encompass the former and to resist pressure. The air cavity which is created between the two layers is linked to the outside of the bottle via a fissure which follows the rim of the mouth of the bottle along the edge of the screw threads where the cap is screwed on. The cap used on this bottle has characteristics which enable us to send air into the bottle itself and to direct it into the air cavity between the two layers. Thanks to this system we can raise the level of the liquid in the bottle even after its partial consumption and the pressure previously present in the bottle will thereby return to its original level.The cap is also equipped with a vent pipe (6) which allows the air to escape from the chamber containing the liquid when the tap is closed and air is introduced into the air cavity. The vent pipe adjusts internally to the amount of air required to cover the liquid inside the bottle and is equipped with a double function float valve (18) which allows the air above the liquid to escape from the bottle and which closes when it is reached by the liquid, thus enabling the bottle to compress and the pressure inside the bottle to return to its original level. This raising of the liquid and the pressurisation of the bottle limits the evaporation space of the carbon dioxide present in the liquid and enables us to preserve its effervescence for a longer period. This instrument has been developed using the chemical principle according to which the quantity of gas dissolved, at a given temperature in a given quantity of liquid, is directly proportional to the gas pressure on the surface of the liquid.

Description

Bottle with cap that allows you to maintain the state of effervescence and integrity of a liquid contained in it even after partial consumption of the liquid.

Summary.

The present invention relates to a bottle to contain liquids consisting of a double envelope, one placed inside the other; the internal casing will have the function of containing the liquid, while the external one will incorporate the internal one and withstand the pressures exerted; the gap that is created between the two containers communicates with the outside through a slot that borders the "mouth" of the bottle at the beginning of the thread where the cap will be screwed. The cap that is used on this bottle has the characteristics that allow us to introduce air into the bottle itself, conveying it in the cavity between the walls of the two containers and thanks to this system we are able to raise the level of the liquid contained. even after its partial consumption and restore the original pressures of the bottle.

The cap is also equipped with a vent tube that will allow the air to escape from the chamber where the liquid is present when, with the cap closed, air is introduced into the cavity.

The vent tube has an internal length suitable for how much air you want to remain above the liquid inside the bottle and is equipped with a dual function floating valve, which will allow the air above the liquid to escape from the bottle and which will close when it is reached by the drink, thus allowing the bottle to be compressed and the pressures inside it to be restored. Through this process of raising the liquid and pressurizing the bottle, we limit the evaporation space of the carbon dioxide added to the liquid and therefore maintain its state of effervescence and integrity for a longer time.

The instrument was designed using the principle of chemistry according to which the quantity of dissolved gas, at a given temperature, in a given quantity of liquid, is directly proportional to the pressure of the gas at the surface of the liquid.

Current state of the art.

The most effective methods so far prepared to limit the dispersion of carbon dioxide contained in a liquid and therefore the consequent loss of its effervescence after partial consumption are the following:

1) the bottles have been fitted with a screw cap that allows them to be closed hermetically after use;

2) in the specific case of beverages, small containers have been placed on the market to limit the space in which carbon dioxide can disperse after the liquid contained in them has been partially consumed and consequently the total consumption of the product after their opening;

3) a device was also devised that compresses bottles using a complex system of levers and pulleys, (reference cited: United States Patent 5,025,953 06/1991 Doundoulakis).

4) a further system is to use a tool that compresses bottles in deformable material after a partial consumption of the liquid contained in them, and which maintains the compression position even after the cap has been closed again by means of a system of rectilinear toothed gears, ( reference cited: Patent n. 0001329606 of 21/11/2005)

Description.

The present invention relates to a bottle equipped with a cap suitable for containing liquid and which maintains the state of effervescence and integrity of the latter over time even after partial consumption. This instrument, which for the sake of simplicity we will call "bottle" below, is made up of two casings, one placed at the end of the other; the innermost envelope that we will call "internal container" (Fig. 4 n 13) will contain the liquid, the external envelope we will call "external container" (Fig. 2,4 n 12) and will have the function of incorporating the internal one and to maintain the pressures, while the spacing that will form between the two containers we will call "cavity" (Fig. 4,5,6 n 20), the cap that will seal the "bottle" we will call "cap" (Fig. 1) and will be equipped with a particular valve that we will call "floating valve" (Fig. 1 n 18), the initial part of the bottle or where there is the thread to screw the cap, we will call it "neck of the bottle" (Fig. 2 n 5), we will call "carbonated drink" liquid with the addition of carbon dioxide and we will call "still liquid" any type of fluid without the addition of carbon dioxide (Fig. 3 bis, 4.6 n 15).

One of the problems that companies producing liquid goods, in the specific case of beverages contained in bottles or similar containers, are faced with the sale of their products, is given by the fact of being able to place on the market drinks that for the most as long as possible they can remain unchanged in quality, taste, fragrance and effervescence even after their partial consumption. Thinking for example of the common case of a "carbonated drink", we know that when the cap is sealed it has a high concentration of carbon dioxide, proportional to the pressure exerted by the same gas dispersed in the empty space inside the bottle. After opening the bottle, with the gradual consumption of the contents and with the passage of time (Fig. 3), the carbon dioxide is dispersed in an increasing volume of air, decreasing its concentration in the drink and causing its loss. of effervescence and integrity.

Our invention aims to reduce the space in which carbon dioxide can disperse, reducing the air in contact with the liquid and bringing it under pressure.

It was conceived using the principle of chemistry, according to which the quantity of dissolved gas, at a given temperature, in a given quantity of liquid, is directly proportional to the pressure of the gas at the surface of the liquid itself.

The characteristics of the invention refer to the attached drawings, in which:

FIG. 1 represents the vertical section of the "cap" of the "bottle" FIG. 1 section a-a represents the longitudinal section of the "cap" on line a-a and highlights the internal structure of the "cap" seen from above.

FIG. 2 represents the enlarged detail of the upper part of the "bottle".

FIG. 2 sec. a-a represents the longitudinal section of the "bottle" and highlights the anchoring of the two casings on the neck of the same.

FIG. 3 represents the moment in which we partially empty the "bottle" of the liquid.

FIG. 3 bis. is the enlarged detail of FIG.3.

- FIG. 4 represents the vertical section of the “bottle” containing the partially consumed liquid (No. 15), while air is introduced through the valve (No. 1) on the “cap”. The air enters the interspace (No. 20) and compresses the internal container (No. 13) causing the liquid to rise towards the "floating valve" (No. 18). The air above the liquid and therefore present in the "internal container", flows through the "floating valve" and exits the "bottle" through the vent tube (No. 6) and from the holes (No. 7) on the "cap",

FIG. 5 is an enlarged detail of FIG. 4

FIG. 6 represents the vertical section of the "bottle" containing the liquid (# 15) which has reached the "floating valve" (# 18) which is thus closed. The additional air that is introduced "into the cavity" (No. 20) puts the "bottle" under pressure, restoring the internal balance between the gases present in the liquid and the air above.

FIG. 7 represents the vertical section of the upper part of the "bottle" under pressure with the partially consumed liquid. The cap is closed, the "float valve" is plugged and the internal liquid has once again reached the stability that prevents gas leaks.

We premise that the proportions, the shapes of the objects and the materials represented in the attached and described tables, may vary according to the needs of the manufacturer, remaining however and always protected by this patent.

When we open a “bottle”, there is an upset of the balances present inside it; these balances before its opening were the guarantee of being able to keep the product for longer. The situation worsens the more we consume the product and the more air we introduce to its contact.

Thanks to this "bottle" we are able to restore the natural balance of conservation of the "carbonated drink" or "still liquid" by eliminating excess air and restoring the pressures in the container and in the liquid contained.

The procedure is as follows: once the "bottle" has been opened and the contents poured (Fig. 3 and Fig. 3 bis) the cap is screwed on, and through the valve (Fig. 1, 4, 5, 6 n i) is introduced of the air (identified in figures 4, 5, 6 with the small black arrow) that will flow inside through the flow channels (Fig.l, 5 n 2) "into the interspace" (Fig. 2, 3 , 4, 5, 6 n 20) causing compression of the "internal container" (identified in Fig. 4, 5, 6 with the white arrow) and thus obtaining an increase in the level of the liquid (identified in Fig. 4, 5 with the gray arrow) contained therein (Fig. 4 n 15) until reaching the “float” (Fig. 6 n 3).

This happens because the air above the liquid will flow out of the slits (Fig. . 4,5 n 6), will come out from the holes placed at its top (Fig. 4,5 n 7).

When the liquid reaches this "float valve" (Fig. 6 n 18) it will cause it to raise the float it contains (Fig. 6 n 3), closing hermetically, preventing further outflow of air.

From this moment on, the further introduction of air "into the cavity" (Fig. 6 black arrow) will increase the pressure inside the "bottle" until the desired internal equilibrium is reached (Fig. 7 double black arrow).

The "bottle" consists of two casings one inside the other (Fig. 4, ni 2 ni 3); "The external container" (Fig. 4 n 12) will be more resistant because it will have to resist the pressures that will be inside the "bottle", while the "internal container" (Fig. 4 n 13) may be less consistent and in deformable material, such as the plastic material still used today for plastic bottles containing natural water marked PET, and with the upper part or the one below the "neck of the bottle" (Fig. 2 n 5), of more rigid material or often (Fig. 2 n 16) such as to give shape and body to the "internal container" during the compression phases, so as not to compromise the functioning of the invention.

Π "external container" (Fig. 4 n 12) will preferably be made of non-transparent material, to prevent the view of the internal container after the compression phases as it could be unpleasant to the eye.

The two casings are anchored to each other, in the central part of the bottom of the "bottle" (Fig. 4 ni 7) in such a way as to allow uniform compression of the "internal container"; they are also fixed to each other on the "neck" of the bottle (Fig. 2 n 14) with tabs placed longitudinally and alternated along its circumference, such as to distance the two wrappers, anchor them together and allow the the passage of air inside the “interspace” (Fig. 2, 5 n 20) for the compression of the “internal casing”.

the upper edge of the "external container" (Fig. 3 BIS n 12) is lower than that of the "internal container" (Fig.3 BIS n 13) so that the liquid (Fig. 3 BIS n 15) hardly infiltrate "into the interspace" (Fig. 3 BIS n 20) when it is poured.

The cap (Fig. 1) consists of a hermetically sealed valve (Fig. 1 n 1) that allows the passage of air in one direction only (towards the inside of the bottle), a flow channel (Fig. 1, 5 n 2) which conveys the air inside the "interspace" (Fig. 5 n 20), a disk (Fig. 1 n 10) with a hollow (Fig, 1 n 8) that forms the flow channel and acts as a closure of the "internal container" of the "bottle".

This disk (Fig. 1 n 8) is reinforced by supports (Fig. 1 n 9) which give rigidity to the closure of the "internal container" and at the same time allow the passage of the air through the flow channel (Fig.1T5 n 2 ). A protuberance is created above the thread of the cap, also equipped with a recess (Fig. 1, 5 n 11) which acts as a closure of the "external container". This is done in such a way that during the opening of the bottle, by means of the "cap", there is first the decompression "of the cavity" and in a second moment of the "internal container", to do this it is necessary to balance the heights of the two casings with respect to the "cap", thus preventing the drink from escaping from the "internal container" which otherwise would still be under pressure.

The "plug" inside has prepared a duct for the outflow of the air of an adequate length for how much air we want to remain above the liquid; this duct is composed of a "floating valve" (Fig. L n 18) which will close when it is reached by the liquid, (Fig. 6 represents this moment), by a vent tube (Fig. 1,5 n 6) at the top of which, in correspondence with the attachment with the "cap", small holes have been made ( Fig. 1, 4,5 n 7) which allow the air to escape outside the “bottle”.

The float of the "float valve" (Fig. 1, 6 n 3) has a specific weight lower than that of the "drink" and this to make it rise from the liquid until it reaches the restriction of the vent pipe (Fig. 1, 5 n 19); once it reaches the restriction of the breather pipe, the float closes it hermetically, thanks to its ergonomic shape, and therefore also closes the "internal container" allowing the subsequent pressurization of the liquid contained (Fig. 7).

The "float valve" is equipped with large lateral slits (Fig. 1, 4,5 n 4) which have the function of: allowing the outflow of air with the valve open, allowing the liquid to raise the enclosed float inside and to be able to clean it from any residues contained in the liquid, in order to make it always functional over time. To introduce air into the cavity, you can use a small electric compressor calibrated in such a way that it automatically stops at the desired pressure. In the specific case of "carbonated liquids" the compressor will be calibrated to the pressure that allows the right balance between the dispersion of the gas in the air above the liquid and that dissolved in the liquid itself, while for "still liquids" but still perishable, the compressor will be calibrated at the optimal pressure to restore the pre-existing balances before opening the container.

A further system for introducing air into the "cavity", in the event that there is no electricity, can be the use of a hand pump; in this case it will be more difficult to reach the optimal pressure, but the use of the pump will ensure that the excess air above the liquid is removed, thus closing the "floating valve". In this way, for "carbonated liquids" it will be the gas itself contained within the liquid to bring itself under pressure and find the balance between dispersion in the air and dissolution in the liquid itself, while for "still liquids", we will obtain a considerable decrease of the air to their contact and therefore we will have less possibility of deterioration.

This invention, in addition to keeping a drink sparkling, also has the function of minimizing the thermal variation of the liquid contained inside, as the cavity that is formed between the two containers also acts as a thermal insulator.

Another feature of this container is that which allows us to cool the liquid contained inside and keep it cold; c it is sufficient to introduce, after a partial consumption of the liquid, "cold air", such as the liquid air contained inside the spray cans, this, thanks to its pressure, will raise the liquid until it reaches the floating valve , the cold air will cool the internal liquid and the cavity will keep it cool as it is isolated from the outside.

During the realization phase of our invention, modifications of the construction type and materials used may be made, such as to facilitate its construction, to make the manufacturing cost more contained or to improve its yield, it is however understood that said possible variations are to be understood totally protected by the present invention.
