Description

Bottle cap.

Field of the Invention

This invention concerns a new plug that is especially useful for closing containers that contain different types of drinks, mainly beverage bottles such as wine, cider, champagne, etc. More specifically, this invention is related to a bottle cap that offers several advantages and that allows to replace the traditional means of closure, as is the case of the cork stopper of the wine, and that serves for the same purpose.

Background of the invention

In the beverage industry, a large number of screw caps and lids for the containers, particularly for bottles, since these are the most commonly used in order to contain drinks of all lessons. For the sole purpose of mentioning only a few examples of more widely known plugs, we can start by referring to the crown cap which, although offers many advantages Functional, such as leak prevention and safety, is not a suitable plug, from the aesthetic point of view, for the purpose of closing more expensive drinks, such as wine or champagne; in addition, it lacks certain characteristics relevant to this class of beverages, as is the case with safety mechanisms.

Another kind of plug very commonly used in the market is the so-called "theft-proof", which serves to in order to prevent leakage and safety, but presents the inconvenience of its high cost and therefore can only be used in those cases where it is justified by the Price of the drink in question.

In the particular case of wines, there are basically two types of bottle caps: for wines of lower price, agglomerated cork is normally used, and For the most expensive wines, a quality cork is preferable. As is known, cork is a natural material obtained from cork oak which, although it offers the product an appearance Excellent aesthetics, involves innumerable problems. In fact, the Cork must be properly shaped and placed; in another case, It can affect the drink. Moreover, it is known that most Cork types, as they are of plant origin, interact with the wine content in the bottle during pre-sale storage. Finally, cork is a high price plug; therefore in the case of low-priced drinks, the second cork is used class, called agglomerated cork, which consists of small cork pieces compacted and joined; this type of cork is not Suitable for high quality drinks.

Another type of stopper for cider, champagne and Some kinds of wine bottles, are the plastic caps Commonly used to close bottles of cider. Not however They are good for high-priced drinks, as they entail countless inconveniences, especially due to the adjustments inadequate between the cap and the inner surface of the neck of the bottle, as well as the difficulty of removing it.

For the document GB-A-1 140 840 a plug is known bottle as defined in the preamble of claim 1. In the US-A-3 823 841 is disclosed a closure system for a bottle, comprising a lid threaded metal, an intermediate block of cup-shaped rubber and a tear aluminum outer lid.

As a consequence of the above, it has developed the plug that this invention concerns; combines several features that result in a new plug that it serves an excellent purpose and whose advantages are the following.

a) Offers a total closure that prevents entry of oxygen, as well as a tightness, and is able to tolerate internal pressures, such as those generated by beverages such as Sodas, sparkling wines, beer, cider, champagne, etc.

b) It has a highly competitive price, in comparison with other types of multifunctional plugs, for example Corks.

c) When the bottle is opened, the cap can be easily removed, without requiring the help of any device external, such as a corkscrew and the like.

d) It has an aesthetically appealing appearance, which is comparable to that of the highest quality, found in The good wines.

Brief Description of the Invention

In summary, this invention relates to a plug for bottles containing drinks in general, particularly wine, champagne, cider, soda and the like, comprising:

1) a metal cover with a coating (lining) internal plastic, in order to reach a hermetic seal, and a threaded system or similar to "remove turning ", which allows quick opening;

2) a plastic bucket of suitable hardness, with a negative impression or interlocks that hold and match external interlocks of the metal cover, and whose diameter exterior has certain vertical grooves that give rise to a anti-rotating interlock mechanism, when placed inside the aluminum outer cap;

3) said plastic bucket, in turn, has a protruding circular part intended to fix the metal cover on the referred plastic interlock when the system is opened;

4) an aluminum outer cover, whose diameter internal interlocks with the outside of said plastic bucket, of a a cylinder-like and closed way, at one end of which the two pieces mentioned above are placed. May have different width and length, according to the purpose to the which is intended to serve, and contains circular threads or bridges brittle, in order to ensure the safety of content.

Detailed description of the invention

In accordance with the preceding descriptions and the illustration provided by the figures attached thereto, a plug in accordance with this invention, and indicated with the numerical reference 1, comprises a metal plug or cover 2 with a plastic inner coating or lining 3, in order to reach the seal between the upper edge 4 of the mouth of the bottle 5. In addition, said upper edge of the mouth 4 has several protuberant grooves that define a system 8 called "for turning out" or a helical thread, while interacting with the screw thread, thus allowing a quick opening. This system will not be described in detail, due to the fact that it is well known in the state of the art, and it is not new (see the
Figures 1 and 1A).

The metal plug mentioned above is placed inside piece 6, which defines the shape of a plug that present, on its outer side, a flat top surface 7 and a perimeter wall 8, while inside it has a hollow space that It has a shape that resembles that of the metal plug. Once the piece 2 is fixed inside piece 6, define a body indivisible that works like a plug that is turned out, by time lacking the appearance of a traditional metal plug, that would deteriorate the appearance of the pieces thus assembled.

The part 6, mentioned above, is defined by a "cube", block or plastic capsule having an appropriate hardness, with negative impressions 9 or interlocks that hold and coincide with the external interlocks 10 of the metal plug, and whose outer diameter It has several vertical grooves that give rise to an anti-rotating locking mechanism at its junction with the
cover 11.

The set is completed with an external cover 11 of aluminum, whose inner diameter is interlocked with the outside of the mentioned plastic bucket 6, in a manner similar to a cylinder and closed at one end, on which the two parts are fixed indicated above. This cover can be of different width and length, according to the purpose to which it intends to serve, and It contains a safety device to avoid alterations of the bottle content that, depending on the type of design, can be shaped like circular threads or brittle bridges, so that guarantee the security of the content, as will be explained to continuation.

Figures 3 and 4 show two different types of manufacturing, in one of which (Figure 3) it is illustrated that the aluminum outer cover 11 has two threaded lines 12 that form a safety band 13 presenting, as is already known, a tear-off tongue 14 to be grasped by the user and, when pulled, removes the band 13 from the body of the lid 11. On the other hand, in the alternative design illustrated by Figure 4, a series of aligned threads 15 is shown that they define brittle bridges 16 that have to be cut by the user to release the contents of the bottle. In the alternative design of Figure 3, the lid 11 has internal anti-rotating interlocks that coincide with the interlocks of the bottle that hold the lid 11 in relation to the mouth, thereby preventing its
turn.

The closing process in this plug design It must be carried out in two stages of closure. In the first, it place the metal cap, and in the second place in the lid external 11 of the bottle containing the interlock 6 of plastic. Said cover 11, when placed in the mouth of the bottle, previously closed with 2, gives rise to the mechanism of interlocking between pieces 6 and 2, and the machine roblona plugs the mentioned cover 11 under the ring 13 (in both alternatives). It should be noted that the skirt of the cover 11 has 20 anti-rotating interlocks that allow the aforementioned cap is locked in the bottle (alternative 3).

Moreover, in the case of the designs illustrated in Figures 3 and 4, it can be seen that the outer cover 11 has a lower skirt 17 which, on the one hand, helps improve its appearance, since a certain label can be applied to your external face I announce; on the other hand, it has a central notch 18 that keeps the set on the mouth of the bottle at the same time That guarantees your safety.

The design in Figure 5 shows another plug similar to those described above, although this time to the lid external missing the referred lower skirt, but has one more short, and the central notch in this case is replaced by a notched joint 19 that holds the assembly to the mouth of the bottle.

The design illustrated by Figure 6 is similar to the previous one, although in this case the body of the cover 11 has a series of threads 15 defining brittle bridges 16 that guarantee the safety of the
plug.

Finally, figure 7 shows another design similar to the previous one, although in this case the shape of the cover 11 It has a convexity that gives it a suitable appearance for be used in bottles of champagne, cider, sparkling wine, etc.

It should be noted that the surface of the lid 11 it can be printed in its entirety, either with a painting on different colors, lacquers or polished, embossed printing, etc.

Finally, it is worth mentioning that when use the cap on champagne bottles, you can give it the form illustrated in figure 7, so that it resembles the plugs traditional, while in the case of soda, beer and similar, the designs of figures 5 and 6 may be used because that the external appearance of the cap is similar to that of the Traditional

It can be concluded from the above that, by means of an ingenious combination of elements, a Highly functional and economical cap, allowing to make it minor alterations without departing from the invention, as defined in the appended claims herein.
