Abstract

Disposable container.

Being able to present very different configurations common in containers to contain drinks, food or other products, the package of the invention allows to obtain a package that resulting rigid enough during use as such container, turn easily deformable at the time of its elimination, to reduce its volumetric occupancy as such residual product

To do this, the body (1) of the container participates a double wall (3-3 '') determining a narrow enclosure (4) enveloping and sealed, so that in said wall participates plastic sheets of reduced thickness thanks to the chamber defined between them gives the container a remarkable deformation resistance.

The container may be equipped with an element valve or similar to allow deflation / inflation of the same in order to modify the volumetric occupation of it.

Description

Disposable container.

Object of the invention

The present invention relates to a container, specifically to a disposable container, of the type obtained base of plastic materials, such as PET, to contain drinks, food or other products, although it may be obtained also from other usual materials in this type of packaging

The object of the invention is to achieve a container which is rigid enough during use as such container, turn easily deformable at the time of its elimination, to reduce its volumetric occupation as such residual product

Background of the invention

There is a wide variety of containers obtained from base of plastic materials, which are used for the marketing and consumption of products also very varied, which range from the configuration of a classic bottle or tray, to any modernist design.

The common denominator to all this wide range of packaging is a problem of material consumption, that is of the plastic or raw material constituting such containers, since a certain wall thickness is required for reasons of container stability, when it is taken by hand, thickness wall much higher than it would be necessary for the container exclusively fulfill its container function, not seeing subjected to manual deformations.

So, if the container is very thin wall It is excessively deformable and hard to handle, and if to solve this problem, the wall thickness of the same, this brings with it a greater consumption of material and a greater difficulty of minimizing the volumetry of the container when This is discarded as waste.

Description of the invention

The package proposed by the invention resolves the problem was fully satisfactory before exposed, so that during use as such a container it has a stiff enough in its walls enough to determine comfortable handling thereof, and yet such rigidity is easily disposable at the time the package is going to be at your once eliminated because the total consumption of its content, and all with a minimum participation of material, as will be seen later.

To do this and more specifically the container that it is recommended to focus its characteristics on the fact that its wall It is double, being constituted with two thin sheets plastic, duly related to each other to define a narrow chamber, so that the air contained in said chamber, which may be pressurized or at atmospheric pressure, gives the container body a high degree of structural rigidity no need to incorporate a greater amount of material, and It is not a problem at the time of discarding the container since it is enough to cancel the tightness of said chamber, by means of a drain valve or any other mechanism appropriate, or even by a simple cut or prick of the same, so that the container can be profusely wrinkled and become an object of small dimensions.

It should be noted that the aforementioned air chamber envelope, in addition to stiffening the body of the container as such, acts as a thermal barrier, a result of special interest when the packaging is intended for the marketing of beverages that must be consumed cold or hot.

So, the larger the container, and given the special structuring of it, the lower its volumetry in the time of disposal compared to other containers of identical dimensions and with a conventional structure.

By cons, it should be noted that, especially when the package is planned to have large dimensions, it can be supplied deflated, to have a minimum volumetric occupation in its transport and storage, being able to be easily swollen at the time deemed convenient, to through the valvular element associated with it.

Description of the drawings

To complement the description that is being performing and in order to help a better understanding of the characteristics of the invention, according to a preferred example of practical realization of it, is accompanied as an integral part of said description, a set of drawings where with character Illustrative and not limiting, the following has been represented:

Preferred Embodiment of the Invention

In the example of practical realization depicted in figure 1 is a package that corresponds to the classic "boat" of beverages, based on a body (1) substantially cylindrical, with slight extensions conical trunk at its bases, in one of which, obviously the upper one is the opening mechanism (2).

Well, this classic type container, intended according to the invention to be made of plastic material, presents as a peculiarity a double wall (3-3 ') so that within it a camera is established waterproof (4) which, as previously stated, can even pressurized

This allows with a very thick wall thickness fine for the external (3) and internal (3 ') partitions, that is to say with a participation of plastic material in the minimum container, said container offers a high degree of structural rigidity during its use for the consumption of the beverage, which ensures a Good stability in every way.

However, at the time of discarding the container by its monouso character, for example for its recycling, the opening of the chamber (4) causes the body of the container to become a highly deformable element, whose volumetry can be reduced drastically.

As previously stated, this opening It can be carried out by a valve system, by breaking or puncturing the outer wall (3) and / or the inner wall (3 '), or by any other means, without affecting the essence of the invention.

As Figure 2 shows, it is feasible that between the two partitions (3-3 ') of the body (1) of the container between which the chamber (4) is defined, or what is the same within said chamber (4), narrow be established reinforcement partitions (5) that compartmentalize the chamber (4) previously cited in several independent cameras (4, 4 '...) each.

The same features offered by a container type "boat" like the one just described, are made Extensive to any other type of packaging, such as the tray (6) represented in figure 3, where the body of the tray consists of two parallel partitions, one external (7) and another internal (7 '), which define each other a camera waterproof (8) which, pressurized or not, stiffen the tray while said chamber (8) is properly closed, losing said rigidity to facilitate disposal of the same when it occurs the opening of said chamber by any means, also being liable to transform into a residue of volumetry minimum

As it follows from how much has just been exposed, the invention is applicable to any other type of realizable package with plastic materials, such as a bottle, a glass, a "tetra-brik®" type container, etc.

As is evident, the invention is applicable. to any type of container, the examples above being described a small part of the great variety of packaging in the that the invention is applicable.

Claims (3)

1. Disposable container, of the structured type based on plastic materials used primarily in the food industry, so that in its body (1) a double wall (3-3 ') determines a narrow chamber (4- 4 ') envelope and sealed, so that said wall involves plastic sheets of reduced thickness that thanks to the chamber defined between them provide the container with a remarkable resistance to deformation, characterized in that said chamber or chambers are provided with means of opening that allow a quick emptying / filling of the air contained inside, in order that the container completely loses its rigidity and can adopt a minimum volumetric occupancy situation, at the time it is discarded as waste. 2. Disposable container according to claim 1, characterized in that said wrapping and stiffening chamber (4-4 ') can be single or compartmentalized. 3. Disposable container, according to previous claims, characterized in that the chamber or chambers (4-4 ') configured in its wall are capable of containing air at ambient pressure or of being pressurized depending on the level of stiffness required.
