Description

Wine bottle.

Object of the invention

The present invention relates to a bottle specially designed for wine packaging, whose structural features have been conceived in order to allow the realization of said material-based bottle plastic, commonly called PET.

It is therefore the object of the invention to achieve a bottle for wine packaging that, compared to the classic bottles of glass, increase most of its performance and this with a lower cost

Background of the invention

As is known, the aforementioned PET is a plastic transparent, specifically ethylene polyterephthalate, wide use in the food sector and in particular in the field of packaging, both for solid products and for products liquid or pasty

On the other hand and regardless of low quality wines that are marketed in "tetrabrik®" containers, the wine is sold in glass bottles that are closed using a cork or synthetic, silicone or cork stopper.
Similary.

Regardless that it is not conceivable by part of the consumer who can market a certain wine quality in a conventional plastic bottle, with a stopper screw closure, as happens for example with certain types of soft drinks, wine inevitably requires the use of a cork stopper or similar performance from the point of permeability view, so currently they are not used plastic bottles for wine packaging, put that on these bottles implantation would not be possible and adequate stability of the type of cap required.

Description of the invention

The bottle for the wine packaging that the proposed invention has been conceived and structured in order to allow the use of said plastic material, ie PET, for the manufacture of the same, not only maintaining the benefits of a bottle of conventional wine, but enhancing these in a very considerable way, as will be seen later.

To do this the bottle that is recommended, which can be obtained by a classic blowing procedure, based on PET repeatedly cited, focuses its characteristics on the fact that his body is, duly reinforced, by a thickness for the same superior aj 0.4 mm, reinforcement that increases progressively in the first half of the neck of the bottle, to become maximum and constant in its terminal half, where said thickness It is between 4 and 5 mm.

It is achieved in this way that the neck of the bottle is able to withstand the internal pressure of the closure and, as the rest of the bottle withstand the pressure during the maneuver of insertion of said cap.

The mechanical resistance is obtained in both directions, that is with respect to the pressure exerted by the stopper, radial pressure that tends to increase the diameter of the bottle in the neck area, maintaining the nominal diameter of the body and guaranteeing a tight seal, as well as neck reinforcement allows to support insertion efforts of the cap, without said neck deforming, nor the rest of the bottle body

According to another of the characteristics of the invention, the bottle incorporates in the terminal and thicker area of its neck, a pair of external perimeter nerves determining an equally perimeter throat, which allows the bottle preform to be held in the mold of blown. This throat also serves, if necessary, to facilitate the insertion of the cap into the filling machine, holding the bottle by said throat with a fork or
Similary.

This way you get a bottle that in front of conventional glass bottles presents the following advantages:

-

Minor weight, about six times smaller.

-

Best impact module

-

Higher pressure resistance

-

Higher fall resistance.

-

Best recyclability

-

Minor price.

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:

Figure 1.- Shows, according to a view in perspective, a bottle for wine packaging made of according to the object of the present invention.

Figure 2.- Shows an elevation view lateral and in diametral section of the same bottle.

Preferred Embodiment of the Invention

In view of the figures outlined, and in particular of figure 1, can be seen as the bottle that the proposed invention presents a general appearance similar to that of a conventional glass bottle that, depending on the type of wine packaging, its colorant can vary, it can be transparent, as it is the plastic material (PET) from which it starts, or it may be colored by any conventional means.

It can participate in standard PET or PET modified with naphthalate or copolymers that give it higher viscosity and consequently greater barrier effect.

The coloring, as stated with previously, it can be for two reasons, to protect the wine against the action of light, and / or a specific aesthetic appearance.

PET properties can also be reinforced to ensure greater durability of the wine, by example by incorporating additives such as Sepiolites, Kaolinite, Hectorite, Montnorillonite, etc.

In any case, the bottle has a body (1) that, as is conventional in the field of wine bottles, it will be cylindrical, with a superior narrowing (2) of generatrix sharply curved-convex, after which it is established the neck (3) receiver of the cork stopper or similar, not represented in the drawings.

As can be seen from the observation of the Figure 2, the body (1) and the narrowing curved-convex (2) that follows, have a wall reinforced, with a thickness equal to or greater than 0.4 mm, and said reinforcement is progressively accentuated at the beginning (4) of the neck (3), reinforcement that reaches its maximum level approximately at medium level (5) of said neck (3), achieving this progressive thickening of the first half of the neck at the expense of the inner face of it, as can also be seen in the figure 2, so that such progressive thickening does not affect aesthetics outside of the neck, nor to the outer dimensions of its mouthpiece (6), which allow the use of corkscrews conventional.

In the extreme half of the neck (3), the one located above the midpoint referenced with (5), the thickness of the neck is maximum and constant, with a variation in thickness between 3 and 5 mm, because this is the area where the neck of the bottle will suffer greater mechanical stress, specifically due to the tendency towards radial expansion of the cap once it has been introduced in the bottle

Finally, in this terminal half (3) of the the neck of the bottle, and in turn approximately at the medium level, the neck incorporates a pair of perimeter nerves (7), preferably of trapecial profile, which in addition to collaborating in the stiffening of this area of the bottle, define each other a groove or throat (8), also perimetral, which as previously said it has a double function, on the one hand hold the bottle preform in the blow mold, and on the other holding the bottle by said throat, with a fork or similar, during the capping operation, to facilitate the plug insert.
