ES2405754B1 - LIQUID DISPENSER PACK - Google Patents

Abstract

The container, being able to have multiple embodiments, is based on the fact that the internal volume of the same and container of the corresponding liquid product, is gradually being reduced, by a constant pressure, in the same proportion as the volume of liquid that is consumed or dispensed from the container, all in the absence of access to the interior air during consumption or dispensing of the liquid. In the case of application of the container to contain volatile or oxidizable liquids for example, it will be avoided that said liquid comes into contact with the air as it is consumed, due precisely to the progressive reduction of the effective volume of the container in the same proportion than the volume of liquid that is dispensed or consumed.

Description

Liquid dispensing container.

OBJECT OF THE INVENTION

The present invention relates to a liquid dispensing container, whose obvious purpose is to allow the exit or dispensing of the liquid contained in the container, through a tap established for that purpose in the body of said container.

The object of the invention is to prevent the access of air to the interior of the container during the operations of dispensing the liquid contained inside, based on a reduction of the effective volume as the liquid content is consumed.

This type of packaging finds special application in liquid products that must be preserved from the air so as not to lose their properties, such as volatile substances such as alcohol, malodorous substances such as ammonia, or complexes such as juices and other beverages, to prevent oxidation, without discarding its use for the dispensing of any other type of liquid, whether chemical or not.

BACKGROUND OF THE INVENTION

There is currently a type of bag often used in the market for the transport of liquids and semi-liquids called “Bag in Box”, which has several drawbacks, for example, there is inside a volume of air that is introduced specifically by the liquid drain openings such as stopcocks or faucets as it is dispensed by gravity and the depression of the bag exerts a force that makes said air enter. It is also customary to introduce a neutral gas for each case, such as nitrogen to neutralize the entry of oxygen into the interior, but this involves manipulating the contents of the bags after their discharge.

As it is known, certain liquids, such as wines, when the container that contains them is uncovered, the product comes into contact with the air, which translates into a noticeably reduced time, oxidizing, losing the properties of the same, giving rise to the so-called "chopped" wine, that is to say sour.

In the same way, in the case of other chemical products, there are also those in which their contact with the air leads to the loss of certain properties of the product or chemical liquid, an unpleasant smell can also occur in the case of smelly products, or even drinks as a result of the fact that at the moment the liquid contained in the package is dispensed, the entry of air into the container is obviously oxidizing the contents, which translates into the problems and inconveniences mentioned above.

DESCRIPTION OF THE INVENTION

The package that has been recommended has been designed to solve the problem described above, based on a simple but highly effective solution. More specifically, the package of the invention is based on establishing a constant reduction of the effective volume inside the package itself as the liquid content thereof is consumed, so that said reduction of effective volume will be in the same proportion as the volume of liquid consumed

or dispensing

To do this, structurally the package is characterized by being constituted by at least two bodies duly related to each other to reduce the effective volume of the package itself as the liquid content of the same is consumed, and in the same proportion, in the absence of access of air to the interior during such consumption. An anti-return valve is established for this purpose in the liquid outlet tube.

A preferred embodiment is that the package comprises a tubular body inside which a container is located as a bellows, which is complemented by its upper end by a cap bearing a helical spring that works in expansion and exerts pressure together to the lid of the container, which carries a tube for the exit of the liquid, so that as the liquid leaves, the body as a bellows is folded by the action of said spring and therefore reducing the internal volume of the container, in order to avoid the access of air to said interior, which translates into the impossibility of oxidizing and / or evaporating certain liquids.

Another preferred embodiment is that the package comprises a tubular body inside which is bellowed, which is complemented by its ends with two caps, one of them as a bottom closure base and another as an upper lid, counting this cap upper with a tube for liquid outlet.

Based on the aforementioned characteristics of the container, in any of the embodiments, the liquid inside the said container will not come into contact at any time with the air, since as it is consumed

With the liquid, the internal volume of the container is reduced, either by telescopicity between the parts that constitute it, or by pushing a plunger inside the container, being able to carry out the push manually, by means of springs as is the case, by rubbers, balloons, or any conventional mechanical element.

Finally, and according to another of the characteristics of the invention, it is provided that the tanks can carry inside or outside a temperature insulating element.

PREFERRED EMBODIMENT OF THE INVENTION

As can be seen in the aforementioned figures, and specifically in relation to figure 1, the container of the invention is constituted by a tubular outer body (1), inside which a perimeter insulator (2) is located, all closed by means of a cover (3). Inside a container (4) of bellows type configuration is located, which is closed at the top by a cap (5) carrying a coil spring (6) that continuously presses the container (4), which through The cap (5) has an outlet tube (7), which is provided with a non-return valve (8) immediately before the dispensing tap (9). When the dispensing tap (9) is operated, the liquid (10) contained in the container (4) exits through the outlet tube (7), overcoming the pressure maintained by the non-return valve (8) at rest. When the dispensing tap (9) is closed, the non-return valve returns to the situation

ES 2 405 754 Al

working, not letting out liquid, or entering air through the outlet pipe (7). In the lower part of the assembly there are two folding legs (11) to lift the assembly so that the tap (9) can pour the contents into a container or vessel arranged in the same base.

In figure 2 it can be seen that the coil spring (6) has pressed the cap (5) until the liquid content (10) of the container (4) is emptied, and that no air has entered inside.

With this same method it can be seen in figure 3 that the container (11) of the liquid (17) in this case is manually pressed due to the pressure exerted on the same cap (12) to defeat the non-return valve (15) so that the liquid comes out through the outlet tube (14). Figure 4 represents the assembly represented in Figure 3 once the entire liquid (17) has been evacuated from the container (11).

Figure 5 represents another embodiment of the assembly, since a liquid carrying bag (27), which is pressed as the first embodiment example, has been arranged inside the container (21) practice by means of a coil spring (24) so that when the outlet tap (25) is operated, the pressure overcomes the non-return valve (26), and the liquid in question can be dispensed. Figure 6 shows this last set, empty of liquid by having pressed the spring (29) the bag (23) containing liquid until the total pressure exerted by the cap (28).

Figure 7 represents another practical embodiment in which it is appreciated that the container is presented horizontally, so as to simplify the design of the assembly, since the liquid (32) goes directly inside the container (31) and The plunger or cap (33) is pushed by the coil spring (34) so that the liquid (32) also comes out overcoming the pressure of the non-return valve (35) when the dispensing tap (36) is opened. Likewise, figure 8 shows the container of figure 7 once emptied.

In the variant embodiment shown in Figure 9, the container is constituted by a tubular body (41) on whose surface of the liquid (42) contained in said container (41), a platform (43) of section substantially less than the section is arranged perimeter of the container (41) that functions as a piston or piston that is constantly pushed by its own weight against said liquid. The piston or platform (43) has a perforation (44) from which a flexible outlet pipe (45), which passes through the cover of the assembly to dispense liquid as soon as the tap is operated

(46) outlet, beating the non-return valve (47). In figure 10 the empty set of liquid content can also be seen.

Figure 11 shows that the tank (53) has a platform (51) that acts as a piston, pressing the liquid (52) inside and that by exerting such pressure when opening the tap (54) causes the outlet of this. Figure 12 shows this assembly once emptied the entire liquid (52).

In Figure 13 it can be seen that the piston pusher element (64) is the outlet tube (61) itself, since it can be the assembly's sealing element, coupling to the assembly by its insertion in the through hole with finned narrowings ( 67) that prevent the withdrawal of the outlet tube (61) .to rest on the hole (68) of the plunger (64). A check valve (69) prevents the liquid (63) from leaving when no pressure is applied to the assembly. The outlet tube (61) can be telescopic so as not to protrude too much when the container is full.

In any of these variants, a malleable liquid-containing bag can be introduced inside the container, as is popularly known by the name "bag in box", as seen in Figures 5 and 6, being coupled by means of the outlet valve to the system emptying, the bag will be coupled to the perimeter of the container depending on the emptying that is produced by the dispensing of the contained liquid, no air entering at any time due to the constant pressure exerted on the container in any of the variants mentioned.

The pusher element that maintains the constant pressure, instead of the helical spring mentioned, can also be any other suitable one, such as a balloon into which the appropriate gas or liquid is gradually introduced. It can also be any manual, mechanical or electrical system that fulfills the same functions.

There may be other ways to reduce the space depending on the dispensing of the liquid contained in the container, which is the main object of the present invention, such as at the level of explanatory and non-limiting examples: two bodies that can be joined together, by two opposing saw teeth whose bodies tend to contract by exerting pressure between them; by two or more tubular bodies telescopically coupled to each other; by two bodies connected by thread so that the volume decreases; a piston commanded manually, mechanically or electrically, etc ...

The containers can be of any size, shape or configuration (prismatic, round square, elliptical, ...) that allows the essential fact that is pursued, which is to reduce the volume of liquid contained depending on its emptying, without air intake in no case.
