LIQUID PRESERVING DEVICE

DESCRIPTION

Technical Field of the Invention

The present invention corresponds to the technical field of devices that treat the conservation of liquids, especially those intended for human consumption, in the attempt to achieve certain characteristics of the environment in which such liquids are found, and thus be able to obtain a conservation in perfect condition of them until their expiration date.

Background of the Invention

At present there is a large number of beverage preservation packages, whose main objective is to increase their durability and preserve them from external agents, avoiding in most cases the addition of preservatives, and thus increasing In addition to the durability of the product, its quality and consumer comfort as well as that of the production, distribution and sale process.

In addition, there is a need to adapt the products or packaging to a reality in which in many cases, the homes are made up of 1 or 2 people and the existing containers in the market are oversized for this family model.

There are currently some products that pose individual formats of them, but this implies a higher production cost that has an impact on the sale price, as well as a greater pollution of the environment, in addition, not all products have this variety.

As a consequence, if a person opens the container of a drink and due to an excessive amount of product for rapid consumption of the same or that for certain circumstances a relatively long time elapses for that type of product without the consumer finishing it, it can be altered even if the expiration date of the same has not been exceeded. This is due to the fact that when opening the container, oxygen, which had been excluded from inside the container, enters it, which begins to react with the liquid product, altering it until it reaches the modification of its properties making it not It is suitable for consumption.

Description of the invention

The liquid preservative presented here comprises a first liquid container body, a second closing body of the lower end of the first body and a third closing body of the upper end thereof.

The second body comprises means for extracting air from inside the first body, while the third body comprises means for retaining or exiting the liquid.

The air extraction means inside the first body are formed by a threaded element external to the second body in its lower part, a piston located in the upper part thereof and rods that transform the turning movement of the external threading element in a vertical movement of the piston.

To do this, in a first option of arrangement of the rods, these are connected by their upper end to the piston and by their lower end to a flat circular element inside the second body.

This flat and circular element of lower fixation of the stems, has circular holes for the passage thereof to a horizontal threaded element in which they are wound. Said threading element is connected in turn with the external threading element, so that when turning, either manually or electronically, to said external threading element, the turning movement is transmitted to the element of internal threading, generating the winding or unwinding of the stems therein. On the other hand, in a second option of arrangement of the rods, these are connected by their upper end to the piston, as in the first option, but by their lower end, in this case each of them leave through a hole at the base of the second body and they are connected to a horizontal threaded element in which they are wound and which is external to said body.

In both cases, the stems are formed of a flexible and elastic material, preferably a steel cable.

When unrolling the thread in which they are, they are pushed up, thus moving the piston vertically.

The length of the same is greater than or equal to the sum of the lengths of the three bodies, because as liquid comes out and remaining less inside the conservator, the threaded element is rotated so that the stems are unwound and move the piston that goes up to extract the remaining air, so that when there is no liquid left, the piston is in its highest position, at the upper end of the third body.

Thus, as the rods are connected by their upper end to the piston, and they are those that generate the elevation of the piston, they need to have a length as defined. On the other hand we have the means of retention or exit of the liquid, existing in the third body.

Said means comprise a narrowing in the outlet of the conservator, a first sliding element fixed to said outlet with a first meshed element attached to its lower part, a second meshed element subject to the beginning of the narrowing and a second free sliding element, located between the two meshed elements. The first sliding element has an upward and downward movement that lets air out from inside the conservator or instead blocks the outlet so that it does not go outside. Thus, in the air outlet position until the vacuum is reached, the first sliding element and the first meshed element are in their elevated position above the outlet, leaving the air inside the conservator, as it is being pushed by the liquid that is rising level due to the action of the piston and, the second sliding element is supported on the second meshed element, while the air passes around it on its way to the exit.

In this way the air goes out until the liquid reaches the second sliding element, at which time, from which it exceeds a certain height thereof, due to density differences, the sliding element begins to rise.

Thus, at the moment when all the air has been extracted and the vacuum inside the conservator is obtained, the first sliding element and the first meshed element continue in their elevated position and it is the second sliding element that has moved until it fits into the outlet. This blocks the exit of the liquid from the preservative.

Finally, if it is desired to extract liquid from the preservative, which is in this vacuum situation, the first sliding element and the first meshed element are moved downwards, so that it also moves down the second sliding element. In this position of said second sliding element, the outlet mouth is unlocked so that the liquid can escape and at the same time it is prevented that by tilting the conservative, the second sliding element falls by its own weight by blocking the outlet mouth again.

This second free sliding element that is between the first and the second meshed elements can be a ball whose diameter is larger than the diameter of the outlet of the conservator. It also complies that its density is lower than that of the liquid contained therein. On the other hand, the first and second meshed elements are rigid, preferably plastic or metallic in nature.

The first body of the liquid conservator may preferably have a cylindrical shape, of a height less than or equal to the perimeter of its contour to allow a correct housing of the rods in the horizontal threaded element in which they are wound, in the lowest position of the piston .

It also includes this liquid conservator, means of connection between the first body and the second and third respectively. These connection means can be by means of anchoring or by threading and, in order to avoid leaks and achieve a tightness of the preservative, said connection means comprise sealing means that can preferably be formed by rubber seals.

In this way, they can be separated both for internal cleaning and in the case of the third body, to be able to make a filling with the liquid of the conservator in a much more comfortable way.

In addition, this liquid preservative can comprise in the external threading element of the second body that forms it, notches indicating the level of liquid existing inside.

This liquid preservative, as a complement of improvement, can comprise a sealed inner element of protection of the conservative.

This element can be formed by a bag of some synthetic material and is closed by its lower end and tightly adjusted in the connection means between the first body and the third. Likewise, it comprises at its upper end the means for retaining or exiting the liquid from the preservative. In this way, the liquid previously packaged in this watertight inner element should only be introduced into the preservative in order to start consuming it. This element rests on the piston and has the same diameter as the conservator. Its height is variable, with a maximum height in its deployed position, equal to that of the first body and that occurs when the piston is in its lowest position. Then, as the piston rises, the element is retracted so that its height coincides at all times with the distance between the upper face of the piston and the connection between the first and the third body.

With this element, which as it ascends, it is refolding and the air inside it is extracted, it is gained in hygiene, since the contact of the liquid with the piston material is avoided.

Likewise, there are liquids that due to their composition can be aggressive for the conservator's walls, such as wine, which can dry and stain the walls, generating in the long term that the piston will not slide correctly.

In addition, the conservator could also be used with this additional element for the preservation of solid products such as rice, coffee, sugar ...

With the liquid conservator proposed here, an important improvement is achieved with respect to the state of the art, since it achieves in a simple way a device capable of keeping the liquids inside it in perfect conditions.

Thus, with this liquid preservative it is achieved that the consumer of the product itself, in a quick and simple way, as the liquid is dispensed can generate the vacuum inside it as many times as necessary so that the preservation of the product In perfect condition it can be insured for a much longer period of time than today.

This conservative is also resolved by achieving maximum sealing of the same so that extended, comfortable and safe use of it is facilitated. Brief description of the drawings

In order to help a better understanding of the features of the invention, according to a preferred example of practical implementation thereof, an integral part of said description is provided, a series of drawings where, for illustrative and non-limiting purposes, represented the following:

Figure 1 .- Shows a section of the liquid conservator. Figures 2, 3, 4 and 5.- They show different states within the liquid conservator.

DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT OF THE INVENTION In view of the figures provided, it can be seen how in a preferred embodiment of the invention, the liquid preservative 4 proposed herein comprises a first liquid container body 1, a second closing body 2 of the lower end of the first body 1, comprising means for extracting the air 13 from inside said first body 1 and a third closing body 3 of the upper end of the first body 1 comprising means for retaining or exiting of the liquid 12.

As shown in Figure 1, the air extraction means 13 inside the first body 1 have a threaded element 5 in the lower part of the outer area of the second body 2, a piston 6 located in the upper part of the area inside thereof and rods 7 whose function is to transform the turning movement of the threaded element 5 of the outer zone into a vertical movement of the piston 6. In this preferred example of the invention the rods 7, which have an equal length or greater than the sum of the lengths of the three bodies, they are formed by a steel cable and are connected by its upper end to the piston 6 and by its lower end to a flat and circular element 9 internal to the second body 2. This element 9 in which the rods 7 are connected at its lower end, has circular holes 10 through which the rods 7 pass through said element 9 reaching a horizontal threaded element 1 1 in which they are wound.

Said horizontal threaded element 1 1 is connected to the external threaded element 5 so that each rotation made therein, which in this preferred embodiment of the invention is carried out manually, is transmitted as a rotation of the horizontal threaded element 1 1 which in turn generates the winding or unwinding of the stems 7.

As can also be seen in Figure 1, the means for retaining or exiting the liquid 12 existing in the third body 3 comprise a narrowing 18 in the outlet mouth 8, a first sliding element 16 fixed to the outlet mouth 8 with a first meshed element 14 attached to its lower part, a second meshed element 15 at the beginning of the narrowing 18 and a second sliding element 17 that can move freely between the first and second meshed elements 14, 15.

In this way, depending on whether the first sliding element 16 with the first meshed element 14 is in an elevated position, the exit of the air 13 from the interior of the conservator 4 is allowed on the one hand as well as on the other hand, when there is no air left inside the liquid preservative 4, it allows the blocking of the liquid outlet 12 by the upward movement of the second sliding element 17 or if it moves downwards, it unlocks the mouth 8 of the conservative 4 even in an inclined position thereof, allowing the exit of liquid 12.

These possible states until obtaining the vacuum inside the preservative 4 and the liquid outlet once the vacuum is obtained, can be seen in Figures 2 to 5. Thus, in Figure 2 a first situation is shown in which the conservative 4, either by partial filling or by a partial partial emptying, is filled with liquid 12 and air 13. The second situation of the conservative 4 represented in the Figure 3 is one in which in order to obtain the vacuum inside the conservator 4, the air outlet 13 contained therein is generated.

In this case, to achieve said air outlet 13, by rotating the threaded element 5, the upward vertical displacement of the inner piston 6 pushed by the rods 7 is generated, so that the elevation of the liquid 12 within the conservator 4 occurs. .

In this situation, the first sliding element 16 with the first meshed element 14 is elevated and the second sliding element 17 located on the second meshed element 15, from where the air passes to the outlet mouth 8.

A third situation of the conservative 4, as shown in Figure 4, is that in which the outlet mouth 8 of the conservative 4 is closed and an internal vacuum situation is reached.

This occurs when the liquid 12, in its ascent pushed by the piston 6, exceeds a certain height of the second sliding element 17. At this time and due to density differences the second sliding element 17 is no longer resting on the second meshed element 15, to rise up to block the outlet mouth 8 when there is no air 13 inside the conservator 4. The first sliding element 16 and the first meshed element 14 in turn continue in an elevated position to allow the second sliding element 17 to rise the mouth 8 exit.

In this way, the vacuum inside the conservative 4 has been generated. In Figure 5, the case can be seen in which the conservator 4 is in a situation of vacuum liquid 12 inside, the consumer needs to extract a certain amount thereof. It is therefore necessary to unlock the outlet mouth 8, for which the first sliding element 16 is moved downwardly next to the first meshed element 14, which in its displacement pushes down the second sliding element 17, the mouth 8 of which is unlocked exit and allowing the exit of the liquid represented by arrows in this Figure. Said second sliding element 17 is formed in this preferred example of the invention by a ball with a diameter greater than that of the outlet mouth 8 and a density less than that of the liquid contained therein.

The first and second meshed elements 14, 15 in this preferred example of the invention are rigid, of a metallic nature.

Likewise, the first body 1 has a cylindrical shape, of a smaller height than the perimeter of its contour and comprises means of connection with the second and third body 2, 3, formed by two threaded elements and to prevent leakage, means of sealing formed by rubber gaskets 19 in said connection means.

The liquid preservative presented here generates a significant improvement over the state of the art because it raises the possibility of obtaining the vacuum of said preservative in a quick and simple way, generating the preservation of the existing liquid inside, that way It remains in perfect condition.

In addition, obtaining the vacuum inside the conservator does not require additional devices or devices to the conservator, so that the consumer of the liquid itself, as it consumes it, generates the vacuum, itself, easily and every time That is necessary.
