Abstract

The invention in question relates to a capsule for a bottle stopper that can be torn off. The configuration of the capsule according to the invention offers a large surface for advertising. The capsule is configured in two parts such that, once the top section has been torn off, the lower part stays in position. This capsule also acts as a tamperproof seal that easily shows if the bottle lid has been opened or not. The configuration of the capsule is based on two essentially parallel lines of weakness that define a lateral tear strip positioned on the means connecting the capsule and the pouring device or bottle.

Description

CAPSULE FOR A BOTTLE CLOSURE

DESCRIPTION

OBJECT OF THE INVENTION

The present invention relates to a capsule for a bottle closure that has the ability to be removed by tearing.

The configuration of the capsule according to the invention allows offering a large area for the inclusion of advertising. The capsule is configured in two parts such that; Once the upper part is removed by tearing, the lower part is kept stable in position.

This capsule is at the same time a guarantee seal that evidences very significantly whether the cap bottle has been opened or not.

BACKGROUND OF THE INVENTION

The closures that include a first means of tight sealing often require a few second closures with various additional functions.

This is the case of some closures by means of stoppers in bottles with dumps that have valves to prevent fraudulent refilling.

In these cases, the incorporation of an external capsule evidences the first opening and also favors the incorporation of advertising on a knurled surface or mechanical means intended for closing. The patent with publication number is known

WO0007898 in which a capsule is additionally incorporated into a cap closure incorporated into a bottleneck with a pouring spout, prepared to prevent fraudulent refilling.

This capsule has a special configuration of fixation and tearing means for its removal. The capsule has a line of perimeter weakening that gives rise to two portions: an upper one and a lower one.

The upper portion has two vertical weakening lines, with the weakening incorporated in the inner part of the capsule surface, in which at least one of them intersects the first perimeter line.

Before breaking the capsule, the perimeter weakening line establishes a division such that both above and below are found means that prevent the capsule from ascending according to the axial direction.

The descent of the capsule is prevented by the presence of the cap; but once the upper part has been removed, this retention is no longer present and the descent only prevents it by wedging the lower skirt on the conical surface of the bottleneck giving rise to the possibility of gaps in the axial direction between the two .

Likewise, the vertical tear requires an upper flange from which the break starts and then continue along the side vertically until the line of weakness that intersects with the perimeter line. Once the tear has progressed to this point, maintaining it results in an advance in the breakage of the lateral weakening line until it exceeds the entire perimeter.

The presence of the upper flange prevents the use of said surface for the incorporation of advertising making use of the entire upper area of the capsule.

Tearing of this type of capsule also requires two changes of direction: from horizontal to vertical; and, from the vertical to the final perimeter section.

The present invention establishes a configuration of a capsule that results in a closure that overcomes these drawbacks.

DESCRIPTION OF THE INVENTION

The present invention consists of a capsule capable of establishing a closure on bottles incorporating a spout. This spout can incorporate, for example, means that prevent fraudulent refilling of the contents of the bottle.

It is also possible that the pourer is not an independent part but is integrated in the configuration of the mouth of the bottle. In this case the capsule can be applied directly on the bottle.

The capsule is from which at least one of the parts is detached by a tearing operation leaving the bottle cap accessible. In the configuration Ration of the invention achieves a tear that occurs on the side of the capsule without interfering on the upper surface which allows the use of the entire area for the inclusion of advertising.

After tearing, the capsule is divided into two sections, a lower one that is attached to the neck of the bottle and a second upper section that is the one that comes off.

The object of the invention is the particular way of achieving these objectives through a configuration that allows the lower part to always maintain an axial retention with respect to the bottle and that the upper section at no time has direct connection with the bottle, only through of the lower portion that has a temporary joint until the tearing operation is carried out.

Establishing the essential characteristics of the capsule for a bottle closure, the characteristics related to its configuration are considered essential, which must be such that the capsule must be formed by two sections joined together and detachable after a tearing operation in the first opening of the closure, therefore it must comprise: a first lower section in the form of an external skirt designed to remain fixed to the bottle after tearing; and, • a second removable upper section through the tearing operation, where the first lower section of the capsule has fixing means intended to be attached either to a bottle spout or directly to the bottle giving rise to axial retention in both directions and with the ability to remain attached to the spout or to the bottle after the tearing operation; and, the second upper section of the capsule, has a tear band on the lateral face thereof defined by two lines of weakening, these lines of weakening being located above, according to the axial direction, of the fixing means that join the lower section of the capsule and the spout.

In the exemplary embodiments, the upper section and the lower section of said capsule are detachable in the tearing operation through the lower weakening line that defines the band. The band is therefore considered as part of the upper section.

The different ways of carrying out the invention according to dependent claims 2 to 13 are considered included in this description by reference.

The closure constituted from this capsule is also considered within the invention. The closure comprises a capsule according to any of the embodiments of the capsule as well as: • a spout to place on the neck of the bottle (the spout can be integrated in the bottle), a cap capable of engaging on the spout to allow the tight seal.

In this closure, the capsule is placed covering the assembly formed by the spout and the cap with a configuration such that: the lower section of the capsule establishes a permanent union with the spout or the bottle, that is, it remains after the tearing operation; and, the upper section of the capsule is free of links with the landfill before and after the tearing operation.

Likewise, closures derived from any combination of dependent claims 15 to 21 are included in the description.

This capsule is at the same time a guarantee seal that evidences very significantly whether the cap bottle has been opened or not. If the bottle has been opened, it will be known because the capsule will lack the upper section. If not, the capsule will be complete.

Therefore, it is understood that while it is a capsule, it is also a guarantee seal.

DETAILED EXHIBITION OF THE INVENTION

A first embodiment of the invention is shown in Figures 1 to 5. In particular, in the section of Figure 1 a boat neck is observed. lia (1) on which a set that prevents fraudulent filling is placed.

This set is mainly formed by a spout (3) that has a skirt (3.1) whose internal face has means (3.1.1) for rotation retention with respect to the bottle (1).

Inside this dump (3), in this example of embodiment, a chassis (2) is retained that retains a valve (4) to prevent fraudulent refilling, as well as two balls (2.1) that increase safety against refilling fraudulent offered by the valve (4).

The pourer (3) is closed by a plug (5) with which it maintains a connection through a thread (3.3, 5.1).

The internal closure assembly plus the cap (5) are covered by a capsule (6) detachable in two portions or sections, one upper and one lower; the latter in the form of an external skirt (6.5).

It is this skirt (6.5) that has a perimeter projection (6.1) on its inner face intended to be inserted into an external perimeter groove (3.2) of the pourer (3).

This perimeter projection (6.1) does not necessarily have to be continuous but, as seen in Figure 5, can be discontinuous.

In this first example, as seen in the enlarged detail of Figure 5, the section of the Perimeter line (6.1) has a small angle (α) of inclination in the lower face that facilitates the insertion of the capsule (6) on the pourer (3).

However, this perimeter projection (6.1) operating together with the groove (3.2) also perimeter of the pourer (3), is such that it offers retention in both axial directions (according to the position shown in the figures) both ascending and falling.

Since this projection (6.1) is inside the lower section or outer skirt (6.5) of the capsule (6); once the upper section of the capsule (6) has been detached, the outer skirt (6.5) is axially secured with respect to the bottle (1) thanks to the fixing with the spout (3).

The upper part of the capsule (6) is detachable by means of two weakening lines (6.2) between which a band (6.3) is defined. The weakening lines (6.2) may for example consist of breakable bridges.

In this exemplary embodiment, the two weakening lines (6.2) are parallel giving rise to a band (6.3) of constant width that ends in a gripping tongue (6.3.1) that facilitates the start of tearing of the band (6.3).

The elimination of this band (6.3) only has one feed that follows the perimeter direction until a lap is completed.

After tearing, the presence of a connecting section (6.4) between the band (6.3) and the portion (6.6) ex- The upper section of the upper section allows that once the upper section of the capsule (6) is detached, the band (6.3) remains connected to the extreme portion (6.6) of the upper section which in this case has an essentially disk-shaped shape. how short are the lateral sections that remain when the band is removed (6.3).

In practice, this section (6.4) is not essential for the indicated tearing mode because, during said tearing, once more than half of the points that join the band (6.3) with the extreme portion (6.6) of the section are broken superior, both (6.3, 6.6) are linked to each other through the stretch of points that have not yet been broken.

In turn, the entire upper section, understanding that it comprises the band (6.3), is separated from the skirt (6.5).

Of the two lines (6.2) of weakening, the lower one is always above the fixing projection (6.1) so that the fixing of the skirt (6.5) is always secured, even having removed the upper section of the capsule (6) .

The end portion (6.6) of the upper section, preferably in the form of a disk, is capable of being used for advertising use by printing or embossing by giving an example.

In a second embodiment, as shown in Figure 6, the band (6.3) is not necessarily defined between two lines of weakening (6.2) arranged parallel but; in their initial section, they have (6.2) an inclination that deflects the final tearing of the band (6.3) towards the upper disc by means of an oblique section (6.3.2) without the band (6.3) being disconnected from the upper portion of the capsule (6).

Although the view is a section, the configuration of the band (6.3) can also be observed from the inside.

In this second example, the perimeter projection (6.1) inside the capsule (6) is continuous and is maintained according to the invention under the lower weakening line (6.2) which gives rise to the band (6.3) of torn.

A third embodiment is shown in Figure 7 in which the weakening lines (6.2) are parallel to each other although they do not continue along the entire perimeter of the capsule (6), but comprise at least two consecutive sectors, that in the example shown in the figure are specified in three sectors.

This division of the band (6.3) into sectors has the advantage that if an adhesive tape is placed on the capsule (6), indicative for example of the corresponding taxes, one of the ends of the adhesive tape could fall on the grip tab (6.3.1) making it difficult to open the capsule (6). By including more than one tongue (6.3.1) to be held in the band (6.3), the user will be allowed access to another (6.3.1) that was not covered by said adhesive tape. Another advantage that derives from this third embodiment is that, since the band (6.3) is comprised of several sectors, the opening of the bottle is more clearly evidenced, since it makes more complex a subsequent attempt to locate each of the sectors in their initial position to hide the opening of the bottle.

Thus, in the embodiment shown in Figure 7, three sectors are defined

6.3.3, 6.3.4, 6.3.5) of the band (6.3) having a constant width, ending each of the sectors (6.3.3, 6.3.4, 6.3.5) on a tab (6.3.1 ) of grip that facilitates the beginning of the tearing of each sector (6.3.3, 6.3.4, 6.3.5) of the band (6.3).

Additionally, the end portion (6.6) of the upper section of the capsule (6) comprises a hole (6.6.1) that in the embodiment shown has a circular shape and is coaxial with the upper part of the cap (5), so that it would leave at sight it, allowing visual access to the plug (5).

Enter at least one of the sectors (6.3.3,

6.3.4, 6.3.5) of the band (6.3) and the extreme portion (6.6) of the upper section there may be a connecting section (6.4) that allows the link between the band (6.3) and the mentioned portion (6.6) extreme It is also possible that this linkage between the two elements (6.3, 6.6) does not exist so that the end portion (6.6) of the upper section is removed after tearing the band (6.3).

In the fourth exemplary embodiment shown in Figures 8a, 8b and 8c a particular mode of linking between the band (6.3) and the end portion (6.6) of the upper section has been established. This linkage is established by one or more ribs (6.7) (two in the example) of very small thickness. The function of these nerves is to show a thickness greater than that of the wall on which they are located. As the usual way to generate the weakening line is by an external cut, if the blade enters only the thickness of the wall, the ribs (6.7) are not cut and maintain the bond between the band (6.3) and the portion (6.6) end of upper section even after tearing.

In this other embodiment, although the bottle (1) is not shown, a design has been proposed that is suitable for applying directly on the bottle (1). It is this bottle (1) that incorporates a groove for the entrance of the projection (6.1) internal fixation to the skirt (6.5). The landfill is in this case integrated in the way the bottle adopts in its pouring mouth.
