Son ampliamente conocidos los envases constituidos por materiales flexibles que contienen líquidos o sustancias informes en su interior. Por ejemplo envases de bebidas, de productos cosméticos y/o de uso clínico, alimentos granulados, etc. Generalmente, se conforman de modo que comprenden una base y paredes laterales, constituyendo en su conjunto un cuerpo hueco hermético. El envase puede mantenerse en posición vertical cuando está lleno del producto que contiene. La dispensación del líquido o sustancia informe, suele realizarse por corte de la parte superior del envase o a través de un tapón dispuesto generalmente también en la parte superior del envase.The containers are widely known made up of flexible materials that contain liquids or Substance reports inside. For example beverage containers, of cosmetic and / or clinical products, granulated foods, etc. Generally, they are shaped so that they comprise a base and side walls, constituting a hollow body as a whole airtight. The container can be kept upright when It is full of the product it contains. The dispensing of the liquid or report substance, usually done by cutting the top from the container or through a cap generally also arranged in The top of the container.
Los envases de este tipo presentan la ventaja que se adaptan a la forma o contenido del líquido o sustancia que comprenden, su transporte resulta más fácil y se aprovecha más el espacio donde están expuestos o almacenados.Packaging of this type has the advantage that adapt to the form or content of the liquid or substance that They understand, their transport is easier and the space where they are exposed or stored.
Sin embargo, los envases constituidos por materiales flexibles presentan algunos inconvenientes derivados de su constitución blanda, que dificultan su manipulación. Uno de dichos inconvenientes es que el envase pierde estabilidad a medida que se va consumiendo el producto, de modo que únicamente se mantienen en posición vertical cuando están llenos del producto contenido. Otro de los inconvenientes es que pueden resultar incómodos de sujetar, puesto que se deforman al aplicar pequeñas presiones.However, the packages constituted by Flexible materials have some drawbacks arising from its soft constitution, which hinder its manipulation. One of said drawbacks is that the package loses stability as that the product is consumed, so that only they keep upright when they are full of the product content. Another drawback is that they can result uncomfortable to hold, since they deform when applying small pressures

Para superar algunos de los problemas mencionados, existen envases dotados de elementos rigidizadores tal como alambres o varas de polímeros rígidos, los cuales se disponen adheridos al material flexible que constituye el envase.To overcome some of the problems mentioned, there are containers equipped with stiffeners such as wires or rods of rigid polymers, which are arranged adhered to the flexible material that constitutes the container.
Otro modo de evitar que el envase se doble o torsione a medida que se va vaciando su contenido, consiste en practicar soldaduras no-lineales entre las láminas flexibles que conforman el envase, o en la misma lámina en el caso de tratarse de un envase fabricado a partir de una lámina flexible doblada. Una realización de este tipo es la descrita en la patente US 5,971,613 de Bell, pero en este caso, no se resuelve el problema de poder manipular fácilmente el envase, sin que el contenido sea vertido por la acción de cogerlo o sustentarlo.Another way to prevent the container from bending or torsion as its contents are emptied, it consists of practice non-linear welds between the sheets flexible that make up the container, or on the same sheet in the case being a container made from a flexible sheet bent An embodiment of this type is that described in the patent US 5,971,613 to Bell, but in this case, the problem is not resolved of being able to easily manipulate the container, without the content being poured by the action of picking it up or supporting it.
También pueden localizarse en el mercado envases rigidizados mediante soldaduras combinadas con dobleces del material. Un ejemplo de este tipo de envase es el descrito en la patente US 5,352,043.Packaging can also be located in the market stiffened by welding combined with folds of the material. An example of this type of package is that described in the US Patent 5,352,043.
