Abstract

The pourer (2) is coupled to the opening of the bottle (3) and has a lateral wall (8) and a base that has a central sector (9) of frustoconical configuration separated from the lateral wall (8) by a crown (10) of broken configuration that alternates crests (11) and valleys (12). The valleys (12) have orifices (13) for the passage of liquid, through which all the remaining liquid returns from the pourer (2) towards the bottle (3).

Description

PLUG WITH BOTTLE FORK, IN SPECIAL FOR

VINAGRE BOTTLES

D E S C R I P C I Ó N

OBJECT OF THE INVENTION

The present invention relates to a stopper with a spout that is used for bottles and that is of special application for vinegar bottles.

The object of the invention relates to the development of a cap specially designed to prevent remaining liquid from being left in the spout after pouring part of the contents of the bottle and once the verticality of the bottle has been recovered, thus favoring the remaining liquid to return ai container in its entirety.

BACKGROUND OF THE INVENTION

In the patent of invention ES 2 137 076 a plug is described that presents a series of improvements that favor its tightness, which is why it is especially useful for application in oil bottles.

This cap is constituted by a base or pouring body that is fixed internally to the mouth of the bottle, with which a flap fixed immovably and externally to the neck of the bottle collaborates, which is related to a shutter by means of a hinge and a tear ring with seal function. The pourer of this cap shows a cup shape from which an outer skirt is extended perimeter that collects on the mouth of the bottle fixing the position of the pourer. The spout incorporates in its interior a prominent central sector with a truncated conical configuration that is provided with a flat upper base from which a vertical cylindrical rod is procended centered, counting on the inclined face of this central sector with a series of triangular windows through which leaves the liquid lodged in the bottle.

Once the cap has been unsealed, the obturator articulates with respect to the skirt, leaving the liquid out through the pouring path. The bottle tilts by pouring the liquid out through the triangular windows.

When the bottle is returned to its original position, part of the liquid that has passed through the windows does not leave the spout because the bottle is recovering its verticality, then this remaining liquid tends to be introduced again inside the bottle.

The aforementioned central rod on the one hand tends to direct the liquid that comes out through the windows by concentrating it uniformly in an exit direction, as well as on the other hand it also facilitates the return of the remaining liquid that is distributed by the inclined face of the sector conical trunk entering through the triangular windows towards the inside of the bottle.

This type of cap is specially oriented for use in oil bottles, but can be perfectly adapted to bottles of vinegar or any other liquid.

Normally in this type of stoppers there is no complete return of residual liquid to the container when it is placed in position vertical, return that will be greater or lesser depending on the surface tension of! liquid.

When it comes to oil, this is of no importance but, when it comes to vinegar, it turns out that this product is an attraction for some insects, as is the case of a certain type of fly that perches on the pourer to rid the residual vinegar

This situation results in a hygienic / sanitary and even aesthetic problem, due to the unpleasant vision of insects on the plug.

DESCRIPTION OF THE INVENTION

The stopper with a bottle spout that constitutes the object of this invention satisfactorily solves the problem described above in that it has a design specially designed to avoid accumulation of liquids in the spout, favoring the return of residual liquid to the bottle when It regains its verticality.

The pourer maintains, similar to the solution described above, the bowl shape and an outer skirt that allows its coupling in the mouth of the bottle, as well as having a prominent central sector with a frustoconical configuration. However, unlike said solution, the liquid passage places are not defined in the inclined face of the central sector, but incorporates holes located in an annular sector or crown that is defined between the inner face of the side wall of the pourer and the base of the central conical sector.

The central conical sector constitutes a continuous surface which maintains the same function of facilitating the oriented sliding of the remaining liquid, but in this case by not having openings it allows directing all the liquid in a focused manner towards the crown in which the liquid passage holes are located.

It is envisaged that the crown adopts a broken configuration that alternates ridges and valleys, the liquid passage holes being defined in the valleys. More specifically, it is contemplated that the valleys constitute horizontal planes, of minimal surface, practically the same as that of the exit and return holes of the liquid, the valleys delimited laterally by ramps or inclined planes, which project in radial direction from the axis of the central truncated conical sector and whose ramps or planes converge on respective ridges, so that each ridge is the convergence of two adjacent planes or ramps.

Each valley is configured from two convergent side ramps towards the bottom of the valley, by a portion of the inner face of the vertical wall of the pourer and by another portion of the central trunk-conical sector, converging the four surfaces in the crown that locates the holes of exit and return of the liquid.

The base of the central frustoconical sector has a great curvature bend that provides continuity between the inclined face of the frustoconical sector and the horizontal plane of the valley, in order to favor the sliding of the liquid towards the hole located in said valley. Likewise, the inner face of the side wall of the pourer defines at its base another curved bend of pronounced inclination with respect to the horizontal plane of the valley. In both cases the couplings converge in decline to favor the continuity of the downward flow of the liquid to the holes, thereby facilitating its evacuation into the container when it adopts the verticality in its resting position. In both cases, as indicated, the bending of great curvature and the pronounced angle chamfer, together with the lateral extensions in ramp, favor the continuity of the downward flow of liquid into the holes. This configuration therefore avoids that there may be sectors in the crown of the landfill that constitute points of accumulation of liquid.

In short, in its application for bottles containing vinegar, the stopper with the pourer thus conceived prevents residual vinegar accumulation and therefore the problem described above.

PREFERRED EMBODIMENT OF THE INVENTION

In view of the figures, a preferred embodiment of! cap with bottle spout that is the object of this invention.

In Figure 1, a plug (1) is shown that has a spout

(2) coupled to the mouth of a bottle (3), which has a shutter (4) and a skirt (5) fixed to the neck of the bottle (3) that is related to the shutter (4) by means of a seal consisting of a tear ring (6) and by means of a hinge (7) with respect to the one articulated by the plug (5), once the plug (1) has been unsealed.

The pourer (2), as seen in Figure 2, shows a general configuration as a bowl equipped with a side wall (8) and a base that has a central sector (9) of truncated conical configuration, separated of the side wall (8) by a crown (10), as seen in Figure 3, which shows a broken configuration that alternates ridges (11) and valleys (12), being defined in the valleys (12) about holes (13) for the passage of liquid in both directions, that is, towards the outside and towards the inside of the container.

The valleys (12) in which the holes (13) are located constitute horizontal planes of minimum surface, practically that of the exit and return holes of the liquid, as shown in Figure 4. Each Valley (12) is delimited by a portion of the internal wall of the pourer (2), another portion of the central trunk-conical sector (9) and by ramps or inclined planes (14), which converge superiorly on the ridges (11), extending both the ridges (11) and the inclined ramps or planes (14) radially with respect to the axis of the central frustoconical sector (9).

On the other hand, in Figures 2 and 5, it can be seen that the base of the central conical sector (9) joins the valleys (12) through a curved bend (15) with a great slope towards the valley (12), to favor the collection of the residual liquid and its return to the bottle (3) through the holes (13)

In said figures 2 and 5, it is observed how in the inner face of the side wall (8) of the pourer (2) a curved bend (16) is defined at its base with respect to the planes of the valleys (12 ) that favors the collection of the liquid and its return to the inside of the bottle

(3).

These curved couplings (15) and (16) can be seen represented in the plan view of Figure 6.
