Abstract

Interior expansion container.

Package for distribution or dispensing of carbonated liquids or similar, characterized by incorporating into the inside of the package a bag or bladder (1-b) (2-b).

This bag or bladder contains pressurized gas, when expanding the pressurized gas forces the bag or bladder (1-b)
(2-b) to occupy the empty space not occupied by the liquid (1-c) (2-c) inside the container (1-a) (2-a).

The pressure that the bag or bladder puts (1-b) (2-b) to the liquid inside the container expels the liquid to the outside through a tap or a similar mechanism (1-d) (2-d).

In the bag or bladder (1-a) it stores pressurized gas in other embodiments gas is injected pressurized by a valve that connects the bag or bladder to the outside of the container

Description

Interior expansion container.

Object of the invention

The present invention aims at a container of internal expansion, dispensing of beverages with gas or some gas mixture, and that presents the added properties of power empty and supply the inner liquid from the container without degassing and without altering the liquid alterations or changes of flavor or composition, pushing the liquid out of the container, and not air entering the container that could come into direct contact with the liquid, and also without contacting the pressurized gas with the liquid

Background of the invention

They are known in the state of the art different types of packaging for beverage distribution Soda or similar.

These containers are sometimes injected with gas pressurized, and on other occasions pressurized gas is stored in a outer container In both systems direct contact takes place between the gas injected into the container and the liquid supplied, what which causes the liquid to degrade and lose its properties characteristics for the consumer.

They also present the inconvenience of the purchase or rental of the container for the storage and distribution of gas to be injected, as well as the cost of the gas itself injects

The present invention solves and solves all this problem, because it allows the liquid to be supplied keep its gaseous and flavor properties intact and composition, and that in turn comes out of the container, without that no outside air enters the container that contacts the liquid, or that the gas used for pressurization contact Nor with the liquid.

Summary of the invention

The inner expansion container is characterized because it incorporates a bag or bladder inside, which Once inside it contains a pressurized fluid medium, which as consequence of its added pressure, means that the bag or bladder occupy the empty space inside the container that does not occupy the liquid inside the container, and therefore subjecting the liquid inside the container at an added pressure that allows its exit from the container for an opening enabled for this purpose, and without the means fluid contact the liquid and no air enters the container that Contact the liquid.

These and other features will come off better than the detailed description that follows, to facilitate which It is accompanied by two sheets of explanatory drawings illustrating a case study that is cited for illustrative purposes but not limiting the scope of the present invention.

Detailed description of preferred embodiments of the invention

In accordance with the purpose of this invention, the inner expansion container is designed so that during transport or dispensing, the liquid in your interior does not suffer from degassing, pollution, degradation or loss of taste, while conferring pressure on the liquid inside to leave the container by itself.

In a first embodiment Preferred of the invention, shown in Figure 1, the package (1) internal expansion of dispensing drinks with some type of gas in its composition, it has a bag or bladder inside (2) (plotted in figure 1) that stores a medium pressurized fluid (2 ') (gas or liquid). As the medium expands fluid (2 ') by its added pressure, the bag or bladder (2) occupies all the space inside the container (1) except the one occupied by the own liquid (3).

The bag or bladder (2), as a result of pressurized fluid medium (2 ') that contains inside, exerts a pressure on the liquid (3) that forces it out of the container (1) by a tap (4) or similar specifically enabled in the container (1), with a pressure proportional to the thrust exerted by the bag or bladder (2) on the liquid (3) inside the container (1).

With the provision explained in this form of preferred embodiment is achieved an autonomous container (1) and with ability to dislodge all liquid (3) from its own interior, and achieving other added qualities, such as empty the liquid (3) from the container without degassing and not suffer the liquid (3) alterations or changes in taste or composition, by not enter the container (1) outside air or contact the liquid (3) with the fluid medium (2 ') (gas or liquid) pressurized inside the bag or bladder (2).

In a second embodiment preferred, represented in figure 2, the expansion container (1) Inside dispensing drinks with some type of gas in your composition, has inside a bag or bladder (2) (represented in strokes in figure 2) to which an injection is injected pressurized fluid medium (2 ') (gas or liquid). This fluid medium (2 ') pressurized is injected into the bag or bladder (2) through a valve (5) enabled in the container itself (1), which forces the bag or bladder (2) to expand against the liquid (3), forcing to be dislodged from the container (1) by a tap (4) or similar specifically enabled in the package (1).

With the provision this other modality of preferred embodiment is also possible to empty the liquid (3) of the container (1) without degassing and without it being altered or changes in taste or composition, when not entering the container (1) outside air or contact the liquid (3) with the fluid medium (2 ') (gas or liquid) pressurized inside the bag or bladder (2), and pushing the liquid (3) out of the container (1), and in addition to everything it can replace the fluid medium from the outside of the container (1) (2 ') inside the bag or bladder (2), in order to confer increased pressure

The invention shown may present the most relevant configuration and components for such functions. You can use the components that have been described or any other components suitable for performing the same type of commitment

The invention, within its essentiality, can be put into practice in other embodiments that differ only in detail from that indicated by way of example, at which will also achieve the protection sought. May, thus, this invention be carried out with the means, components and most suitable accessories, the component elements being able to be replaced by other technically equivalent ones, because everything remains this included in the claims.

Claims (2)

1. Interior expansion container, characterized in that it incorporates inside a bag or bladder (2), which in turn contains a pressurized fluid medium (2 '), which as a consequence of its added pressure, means that the bag or bladder (2) occupy the empty space inside the container (1) that does not occupy the liquid (3) inside the container (1), and therefore subjecting the liquid (3) inside the container (1) to a added pressure that allows its exit from the container (1) through an opening (4) enabled for this purpose, and without the fluid medium (2 ') contacting the liquid (3) and nor that air enters the container (1) contact the liquid (3). 2. Internal expansion container of claim 1, characterized in that the container (1) has a valve (5) that allows the injection of fluid medium (2 ') from the outside of the pressurized inside the bag or bladder (2) .
