Description

DESCRIPTION

Screw cap for carbonated drinks with outlet regulation.

The present invention refers to a screw cap of a special design that, once attached to the bottle, allows a fine regulation of the outlet flow thanks to the longitudinal sliding of the cap itself, with respect to the neck of the bottle. Said relative sliding is achieved by turning the manipulated plug from its head. The advance or retreat of the stopper with respect to the neck of the bottle, for each turn of the stopper, is exactly equivalent to the thread pitch.

Sector of the technique to which the invention refers

The invention presented affects, on the one hand, the Sector of Various Industrial Techniques in its section on Opening and closing bottles, Liquid handling. From the industrial point of view, it affects the manufacturing industry of closure caps for bottles with capacity to regulate the discharge flow.

Background of the Invention

The closure of the bottles by means of caps is a mandatory requirement to avoid spillage of the liquid they contain. It is understood that since there are countless types of bottles, there are also as many types of stoppers.

A first difference between the different types is that, in some cases, they are properly sealed screw caps and on other occasions they are caps that snap on the neck of the bottle or are inserted by pressure inside the neck of the bottles.

In all cases, it is usual that, to dispose of the contents of the respective bottles, the complete removal of the stopper is required, as is the case with beer, vermouth or soft drink bottles, closed with a metal cap. When the stopper is one of those that are inserted under pressure, as is the case with bottles of wine, cava, cider, etc. full removal is also required.

There are other types of closures used in bottles of whiskey, cognac, gin and the like that, on some occasions, incorporate stoppers that do not require the complete removal of the stopper to serve them in glasses or glasses as they are equipped with dosing stoppers that facilitate controlled pouring.

The invention presented in this document responds to this last type with the particularity that it not only describes metering caps but also, the flow of spillage can be controlled at will of the one who serves the beverage. The inventor is not aware of the existence of similar solutions to those included in this document that solves the case of caps screwed directly to the bottle and the case of glass bottles without threads.

Summary description of the invention

The present invention, as it has been exposed previously, refers to a screw cap of special design that allows a fine regulation of the outlet flow thanks to the longitudinal sliding of the body of the cap with respect to the neck of the bottle or with respect to an interposed auxiliary piece.

It is a cap that consists of a handling head and a body that is inserted into the neck of the bottle.

Taking into account that there are screw-top bottles and glass bottles, free of threads, the inventor conceives two embodiments suitable for each one of said bottle typologies. However, the operating principle is the same in both cases as can be seen in the figures that are included in the document as an inseparable part of it.

In the first embodiment, the handling head, in the form of a perforated cap, has an internal thread specially dimensioned to fit normally in the corresponding bottle. The body has the shape of a hollow cylinder with smooth walls, with the particularity that, on the external lateral surface, in its low part and mid-height it has separate toroidal projections dimensioned in such a way that its greater diameter coincides with the internal diameter of the neck Of the bottle. In addition, between both projections a series of evacuation holes are arranged that cross the walls of the hollow cylindrical body.

In the second embodiment, the head is in the form of a perforated cylinder without a thread. The body, integral with the handling head, has a hollow cylinder shape that is threaded in the upper section, closer to the head, and the lower section, with smooth walls, has the particularity that in the lower part it has a projection Toroidal followed by a conical shape that completely closes the base of the cap body. This conical shaped part is provided with a series of evacuation holes that completely pass through the body of the stopper. In this case, taking into account that this type of stopper is intended for use in glass bottles, it is necessary to interpose a part between the body described above and the neck of the bottle with a shape that is also a hollow cylinder with a zone internally threaded top and a smooth bottom area. The base has a hole and the side walls have several grooves for the adjustment of this intermediate piece in the neck of the bottle.

The operation of these two embodiments is described in detail in the corresponding section where it can be seen that the normal actuation of the stopper, in the rotary direction, allows fine regulation of the discharge flow.

Detailed explanation of an embodiment of the invention

Screw cap for carbonated drinks with outlet regulation (Figs. 1 to 5), consisting of a specially designed screw cap that allows a fine regulation of the outlet flow thanks to the longitudinal sliding of its body with respect to the neck of the bottle or with respect to an auxiliary piece interposed.

The inventor, taking into account the existence of bottles that are closed by means of screw caps as well as glass bottles, free of threads, that are closed by means of clamped plates or by insertion of cork stoppers or similar material, describes two embodiments that They adapt to both types of bottles, both solutions responding to the same operating principle.

The first embodiment conceived by the inventor consists of a head (1) and a body (4) manufactured as a single piece.

The head (1), serves to manipulate the cap, presenting the shape of a cap, drilled in its central part, main hole (2), which has an internal female thread, called head thread (1.1), shown in the (Fig. 1).

The body (4), which as we have indicated, is in solidarity with the head (1), has the shape of a hollow cylinder, with smooth walls, crossed by the main hole (2) that affects its entire length, opened by! at the top and closed at the bottom.

This body (4) has the particularity that, on its external lateral surface, at mid-height, it presents the upper projection (4.1) and in the lower part, it presents the lower projection (4.2), both toroidal in shape and dimensioned in such a way that its outer diameter coincides with the inner diameter of the bottle neck (5). On the other hand, between the two upper projections (4.1) and lower one (4.2) there are several evacuation holes (3) that totally cross the walls of the body (4).

With this configuration, since the stopper is placed in a bottle (5), as shown in (Fig. 2), the liquid in the bottle (5) cannot be poured outside because the stopper is in the closed position.

Indeed, the lower projection (4.2) is perfectly fitted inside the neck of the bottle (5) above the break in the neck (5.2) from which the walls of the bottle begin to widen. It is noted that the head (1) is in an elevated position with respect to the mouth of the bottle. In other words, it is something unusual in the closure processes of caps. In this case, turning the head (1) in the traditional counterclockwise direction of loosening, brings us to the closed position.

If we now look at (Fig. 3) we see that the plug, that is, the head (1) and the body (4), as a consequence of having applied a clockwise turn, is in a lower position that the previous one in such a way that the lower projection (4.2), is at a lower level than the neck break (5.2) which allows the liquid in the bottle (5) to pass through the gap between the lower projection (4.2) and the neck break (5.2) then continuing through the evacuation holes (3) with free outlet to the outside through the main hole (2). The liquid can only follow this path since the upper projection (4.1) closes the passage to the outside.

It is understood that this configuration not only procures the closing or opening of the bottle but also allows a graduation of the discharge flow by means of a careful rotation of the cap manipulation head (1). The flow is adjustable in a fork that goes from zero, in closed position, to a maximum that depends on the sum of the sections of the evacuation holes (3).

In the second embodiment, the head (1), has the shape of a straight cylinder, pierced in the center by the main hole (2), and is integral with the body (4), which is shaped like a hollow cylinder with a thread section body (4.3) in the upper part, closer to the head (1) and a section of smooth walls, in the lower part where the lower projection (4.2) is located, toroidal, followed by a conical shape that closes completely the base of the stopper, which is provided with a series of evacuation holes (3) that completely pass through the body (4) of the stopper.

In this case, it is necessary to add the interposed tube (6) between the body (4) and the neck of the bottle (5) in such a way that the stopper can rise or fall, applying rotations to its head (1), when interacting the body thread (4.3), male, with the interposed tube thread (6.1), female.

The interposed tube (6) has an upper section of female thread and a lower section of smooth walls through which the lower projection (4.2) can slide, up and down, when applying rotations to the handling head (1). It also has, on its external lateral surface, a series of grooves (6.2) that adjust the interposed tube (6) in the neck of the bottle (5) in the same way that a conventional stopper does.

This configuration of the cap of the invention in the second embodiment keeps the bottle (5) closed in the position shown in (Fig. 4) where the lower part of the body (4) obstructs the outlet hole (6.3) , whose shape adapts to the conical tip of the body (4).

On the contrary, the liquid can flow outwards if the stopper is actuated to adopt the position indicated in (Fig. 5) where the body (4) has been raised and the liquid can freely pass through the outlet hole. (6.3) to continue through the evacuation holes (3) of the body (4) and continue outwards through the main hole (2). In this case, it is the lower projection (4.2) that prevents liquid from leaking into the body (4.3) and interposed tube (6.1) threads.

Fine regulation of the output flow is achieved in the same way as in the first embodiment.

It is not considered necessary to extend the content of this description for a person skilled in the art to understand the scope and advantages derived from the invention, as well as to develop and put into practice the object of the same. However, it should be understood that the invention has been described according to preferred embodiments thereof, so that it may be subject to modifications without impacting or involving any alteration of the basis of said invention. That is to say, the terms in which this preferred description of the invention has been exposed, should always be taken in a broad and non-limiting manner.
