DESCRIPTION

Stopper with a half pouring

The invention relates to a cap with a pouring means, according to the preamble of claim 1. Normally, said cap is intended for containers (such as bottles) for conditioning a liquid or pasty content, in particular food, such as oil, sauces, vinegar, dairy products or others.

EP-A-0 472 655 describes a stopper comprising a pouring body, which includes an operculum and a capsule, which includes a hinge. The pouring body is part of a base, which includes a concentric inner skirt and outer skirt and which come to cover the edge of the neck of the container, a cylindrical wall directed towards the opposite part of the skirts and whose free edge is slightly retracted towards the exterior, along the entire periphery and finally, a transverse operculum joined by a thin annular veil to the inner skirt, which can be torn off with the help of a pull ring. The capsule includes an apical wall, an outer skirt widely separated radially from the cylindrical wall with free edge folded from the base and an inner sealing collar. The pouring function, guaranteed by the folded free edge, is guaranteed on the entire periphery of the cylindrical wall of the pouring body, which turns out not to be as effective.

Other plugs are known whose base includes a protruding spout, located, which forms a noticeable protrusion, directed radially outwards, generally in front of the pivoting means of the lid. This arrangement presents as a disadvantage the volume of the cap, the inelegant nature of the pouring spout, visible when the cap is closed and finally and above all, the outer dissymmetry of the cap, which requires orientation to manipulate and seal it, the manipulation means being and therefore more complex sealing.

In DE10327335, a stopper comprising a base that forms a pourer, a cover having a peripheral skirt and a joint of the lid on the base is described. The spout has a generally cylindrical wall, the upper part of which is shaped to constitute a protrusion directed radially outward, thus forming a localized spout peak, located in front of the joint. Thus the pouring spout, placed inside the cap when the latter is closed, is invisible from the outside of the cap. The skirt of the lid is devoid of the radially directed protrusion towards the outside typical of a localized spout peak. The cover is provided with a cylindrical sealing collar, which cooperates with the inner face of the wall.

The invention proposes a stopper with a pouring means, whose pouring function is effectively guaranteed by a "oriented" pouring spout, that is to say located at a given site of the circumference of the pouring means, the cap presenting, however, having a general cylindrical shape in its exterior, which avoids the disadvantage of the orientation for handling and the unsightly effect of a visible spout. In addition, the cap according to the invention has a good seal when the latter is closed.

For this, the invention proposes a plug with a pouring means comprising a base, which includes a pouring means, a cover with a peripheral skirt and pivoting means of the lid on the base, in which the pouring means includes a wall generally cylindrical, whose upper part is shaped to constitute a protrusion directed radially outwards, forming a localized spout peak, located in front of the pivoted means, thus being this spout peak, placed inside the cap when this The latter is closed, invisible from the outside of the cap, and the skirt of the lid may be devoid of the protrusion directed radially outward, typical of a localized spout.

According to the invention, the collar is provided with a peripheral flange, which fits into a groove in a complementary manner provided on the inner face of the wall, to ensure improved sealing. The groove of the inner face of the wall is located below the neck, forming the neck of the bottle. Thus, the cap has a double seal. In addition, the fact that a sealing zone is provided at a lower level than the neck, forming the neck of the bottle, makes it possible to prevent a liquid contained in the bottle from extending to the defined area between the two sealing zones.

Other objects and advantages of the invention will become apparent from the following description, made with reference to the attached drawings, among which:

The stopper with a pouring medium, of plastic material and of general axis of revolution Z, is generally intended for containers (such as bottles) for conditioning a liquid or pasty content, in particular food, such as oil, sauces, vinegar, a dairy product or others.

In the embodiment shown, the one-piece plug comprises a peripheral base 1, which includes a pouring means 2, a cover 3 and means 4 for pivoting the cover 3 on the base 1.

The cap is described starting from an assumed vertical Z axis, the base 1 facing down and the cover 3 facing up. It is with respect to this position that the words "above", "below", "above", "below", "vertex" ... The word "axial" refers to the Z axis, while the word "transverse" ”Refers to what is perpendicular to the Z axis. Depending on the context, the word“ internal ”(or“ interior ”) refers to or what is located inside the stricto sensu plug or to what is oriented towards or near the Z axis, while the word "external" (or "external") refers to the contrary.

The base 1 includes an outer skirt 5 of cylindrical shape, directed downwards, arranged for and intended to be fastened on the neck of the container, thanks to suitable fastening means, complementary to each other, such as an overhanging collar or a threaded, provided in this case on the inner side of the outer skirt 5.

The base 1 includes, on the upper edge of the outer skirt 5, an annular twist 6, directed inwards.

The pouring means 2 includes a wall 7, generally cylindrical, contiguous with the inner edge of the annular bend 6. The wall 7, generally with a diameter smaller than that of the outer skirt 5, has a lower part 8 and an upper part

9. The lower part 8 is located in front of the outer skirt 5. The lower part 9 protrudes axially from the outer skirt 5, above the annular turning 6, in a circular sector of approximately three quarters of a turn, located diametrically opposite to the 4 pivoting means.

The upper part 9 is limited at its apical end by a free edge 10 generally flared very slightly outward, extending substantially in a plane that passes substantially through the pivoting means 4, and inclined upwardly facing the means 4, with an acute angle of approximately 10 ° to 30 ° with respect to a transverse plane, for example an inclined plane of approximately 17 °.

In its area of greatest axial height, the upper part 9, cylindrical in shape, is formed at its full height or at least a sufficient height, adjacent to the free edge 10, to constitute a protrusion 11 directed radially outwardly, forming a "oriented" spout peak, that is to say located at a given location of the circumference of the spout means, located in front of the pivot means 4.

For example, for a plug whose base 1 has a diameter of approximately 3 cm and the part 9 has a diameter of approximately 2.5 cm, the protuberance of the pouring spout 11 can be approximately one or several millimeters.

In its general geometry, the free edge 10 of the pouring means is sufficiently radially separated from the skirt 19 of the cover 3, which allows, if desired, to accommodate a larger and oriented pouring spout 11, which allows a more efficient pouring, to the time it remains inscribed in the cylindrical outer volume of the cap.

It is understood that the pouring spout 11, placed inside the cap when the latter is closed, is invisible from the outside of the cap. On the other hand, the skirt 19 of the cover 3 may be devoid of the protrusion directed radially outwards, which would be typical in an external oriented pouring spout. This arrangement avoids the inconvenience of the need to orient the plug to handle and seal it, in addition to the ugliness of a plug

pourer visible from outside the cap.

The pouring means 2 also includes a removable operculum 12 that prevents access to the contents of the container before using it for the first time and protects this content so that they do not penetrate from the outside, contaminants or against oxidation by ambient oxygen.

The opercle 12, arranged transversely, is connected to the wall 7, that is, in the embodiment represented, by its lower part 8, by a thin veil 13 of generally annular shape, which constitutes the operculum detachment line

12.

In its area near the pivoting means 4 and diametrically opposed to the protuberance 11 of the wall 7, the plane of the thin veil 13 is formed forming the detachment line, to constitute a protuberance 14, inscribed in a circular sector with an angle of various grades. The protuberance 14 is directed radially outward. It grants the thin veil 13, seen in elevation, not a perfect circle shape but a general circle shape with an oblong deformation outward at the location of the bulge 14. In the median part of the bulge 14, the veil 13 has a radius of curvature weaker than the rest of the veil 13.

For example, for the cap whose base 1 has a diameter of approximately 3 cm and the part 9 has a diameter of approximately 2.5 cm, the veil has a general radius of curvature of approximately 1 cm, except at the location of the protuberance 14 where, in the median part, the radius of curvature is approximately 3 mm.

The presence of the protuberance 14 facilitates the beginning of the detachment of the operculum 12, by properly locating the shedding force, which decreases the shedding effort by the user. In addition, when the cap is closed, the sealing collar of the cover 3 is prevented from hitting the operculum 12, which will be discussed next.

Above and on the periphery of the operculum 12, an organ 15 is rigidly held in the protuberance 14 that allows the user to pass a finger to pull the operculum 12 to detach it.

In the embodiment shown, the organ 15 is a split ring, that is to say incomplete, although almost complete, joined with the upper face of the operculum by two legs 16a, 16b, peripheral, arranged in axial direction, different from each other, but located one immediately next to each other. The legs 16a, 16b, are joined to the two ends of the split ring 15 by round parts 17a, 17b.

This arrangement makes it easier for the user to run a finger through the split ring 15 and in particular, allows the split ring 15 to be enlarged, which results in a better grip of the split ring 15, which in combination with the protuberance 14 facilitates operculum detachment 12.

In addition, the molding of the split ring 15 can be carried out so that, when the lid 3 is open, the split ring 15 tends to project upward, protruding more than the pouring means 2. This arrangement also contributes to the user coupling better the finger in the split ring 15.

The cover 3 includes a transverse apical wall 18 - flat in the embodiment shown - having an internal face 18a facing down. It also includes, adjacent to the peripheral edge of the wall 18, a cylindrical peripheral skirt 19, directed downwards, limited by a lower free edge 20.

Although the cap integrates a pouring spout 11, the skirt 19 of the cap 3 is devoid of the radially directed protrusion towards the outside typical of a located spout. Thus, the skirt 19 can be externally cylindrical, without protruding significantly. This structure allows the plug to be manipulated as if it were perfectly cylindrical, while the presence in the skirt 19 of a protuberance would require orientation of the plug to allow its manipulation.

From the inner face 18a of the apical wall 18, a cylindrical collar 21 generally protrudes downwards. The collar 21, which has an outer diameter that corresponds to the inner diameter of the wall 7, comes into contact, on its outer face, with the inner face of the wall 7, to ensure tightness.

To ensure a better seal, the collar 21 is provided with a peripheral flange, which fits into a groove in a complementary manner provided on the inner face of the wall 7.

The groove of the inner face of the wall 7 is located below the neck, thus forming the neck of the bottle and the wall 7 cooperates tightly with the apical inner wall 18a of the lid. Thus, the cap has a double seal.

In addition, the fact that a sealing zone is provided at a lower level to the neck, forming the neck of the bottle, makes it possible to prevent a liquid contained in the bottle from extending to the defined area between the two sealing zones.

When the cap is closed, the split ring 15 is limited and comes against the inner face 18a of the apical wall 18 of the lid 6. Furthermore, as indicated, the structure of the veil 13 of the operculum 12 prevents the collar from tightness 13 hit the latter.

The monobloc cap comprises two parts, one that can be called fixed, PF - in the sense that it is rigidly held in the neck of the container - and the other that can be called mobile, PM, associated with each other by pivoting means 4 . The fixed part PF comprises the base 1 and the pouring means 2, while the mobile part PM is formed by a single cover 3.

The two parts, the fixed PF and the mobile PM, cooperate initially, as described, in that the collar 21 cooperates with the wall 7. In addition, the joint plane P of the fixed, PF and mobile parts, PM slopes slightly from top to bottom on the side of the pivoting means 4 towards the pouring spout 11.

The pivoting means 4, functionally associated with the base 1 and the cover 3, guarantee the inclination of the latter around a transverse axis X, between two extreme positions, that is to say a stable closing position and a stable opening position. The extreme opening position is the result of pivoting substantially 180 ° with respect to the closing position. If necessary, the lid 3 can be opened in an intermediate position, for example after pivoting at 90 °.

The pivoting means 4 can be the object of various variants suitable for the structure of the plug.

In the embodiment shown, the pivoting means 4 comprise two protuberances 22 and 23, adjacent respectively to the base 1 and the cover 3, joined by a line 24 of less thickness and less resistance. On one side and the other of the protuberances 24, two incurred parts are provided, elastically deformable.

In the embodiment shown, the cap also includes means 27 regulating the pouring of the contents of the contents of the container, constituted by a plurality of parts (usually called "petals"), which extend from the inner face of the wall 7 of the pouring means 2, slightly below operculum 12, and being directed towards the Z axis, distributed substantially uniformly around said axis, directed slightly downwards and leaving free spaces of passage between them and centrally.

In the embodiment shown, the cover 3 includes on the outer face of its skirt 19, diametrically opposite to the pivoting means 4, a small projection 28, directed transversely towards the outside, offering the user a grip in order to facilitate the opening of the cover 3. Despite the existence of the projection 28, the plug can be handled perfectly as if it were a revolution, because the projection is of limited size in the radial direction.

For the manufacture of the cap, the base 1, the pouring means 2 and the lid 3 are molded by injection, in a single operation, the latter being open. Then, close the cap before mounting in the container to which it is intended.
