Description

OBJECT OF THE INVENTION

The present invention relates to a capsule for a bottle cap that can be removed by tearing.
The capsule configuration according to the invention allows providing a large area for including publicity. The capsule is configured in two parts such that, once the upper part is removed by tearing, the bottom part remains stable in its position.
This capsule is at the same time a seal guarantee that makes it evident whether the bottle cap has been opened.

BACKGROUND OF THE INVENTION

Closures including first sealing closure means often require second closures with various additional functions.
This is the case for some closures using caps in bottles with pouring members that have valves to prevent fraudulent refilling.
In these cases, the incorporation of an external capsule reveals the first opening and in addition favours the inclusion of publicity in a surface free of knurls or mechanical means intended for closure.
A patent is known with publication number W00007898 in which a capsule is added on a cap closure incorporated on a bottle neck with pouring member prepared to prevent fraudulent filling.
This capsule has a special configuration for its attachment and tearing means for removal. The capsule has a peripheral weakened line that gives rise to two portions: an upper portion and a lower portion.
The upper portion has two weakened lines in vertical position with the weakened incorporated in the internal part of the capsule surface, in which at least one of these intersects the first peripheral line.
Before breaking the capsule, the peripheral weakened line establishes a division such that both above and below it there are means to prevent the capsule from rising along the axial direction.
The capsule descent is prevented by the presence of the cap. However, once the upper part is removed this retention is no longer present and the descent is only prevented by the wedge of the bottom flange in the conical surface of the bottle neck, resulting in the possibility of clearances in the axial direction between them.
Similarly, the vertical tearing requires an upper tab from which the tearing begins, continuing along the side vertically to the weakened line that intersects the peripheral line. When the tearing has reached this point, continuing results in the advance of the lateral weakened line until the entire perimeter is covered.
The presence of the upper tab prevents the use of this surface for including publicity, making use of the entire upper area of the capsule.
Tearing this type of capsule also requires two changes of direction: from horizontal to vertical and from vertical to the final peripheral segment.
A capsule of the prior art is also disclosed in WO99/21773
The present invention establishes a capsule configuration that provides a closure that overcomes these drawbacks.

DESCRIPTION OF THE INVENTION

The present invention consists of a capsule that can establish a closure in bottles that include a pouring member. This pouring member can include, for example, means to prevent fraudulent refilling of the bottle contents.
It is also possible that the pouring member is not an independent part, instead being integrated in the configuration of the bottle mouth. In this case the capsule can be applied directly on the bottle.
The capsule is of those in which at least one of the parts is detached by a tearing operation, leaving the bottle cap accessible. The configuration of the invention provides a tearing that takes place in the side of the capsule without interfering with the upper surface, allowing the use of the entire area for including publicity.
After tearing the capsule is divided into two segments, a bottom one that remains joined to the bottle neck and an upper one that is detached.
The object of the invention includes the specific way in which these objectives are achieved by a configuration allowing the bottom part to maintain an axial retention with respect to the bottle and the upper segment not to be directly attached to the bottle at any time, only through the lower segment which has a temporary union until the tearing operation is performed.
As regards the characteristics of the capsule for bottle closures, those considered essential are the ones according to claim 1.
In the examples of embodiment, the upper and lower segment of said capsule can be separated in the tearing operation using the lower weakened line that defines the band. Thus, the band is considered to be part of the upper segment.
The various embodiments of the invention according to dependent claims 2 to 13 are considered to be included in this description by reference.
Also considered as included in the invention is the closure constituted with this capsule. The closure comprises a capsule according to any of the embodiments of the capsule, as well as:

A pouring member to place on the neck of the bottle (the pouring member can be integrated in the bottle);
A cap that can be coupled on the pouring member to provide a tight closure.

In this closure the capsule is placed covering the assembly formed by the pouring member and the cap with a configuration such that:

The bottom segment of the capsule establishes a permanent union to the pouring member or bottle, this is, one that remains after the tearing operation; and
The upper segment of the capsule is free of any attachment to the pouring member before and after the tearing operation.

Similarly, closures derived from any combination of the dependent claims 15 to 22 are considered to be included in the description.
This capsule is at the same time a seal guarantee that shows in a very obvious manner whether or not the bottle cap has been opened: if it has been opened, the capsule will be missing the upper segment; otherwise, the capsule will be complete.
For this reason, as well as a capsule it is also considered to be a seal guarantee.

DETAILED DESCRIPTION OF THE EMBODIMENT

A first example of embodiment of the invention is shown in figures 1 to 5. Specifically, the cross-section of figure 1 shows the neck of a bottle (1) on which is placed an assembly to prevent fraudulent refilling.
This assembly mainly consists of a pouring member (3) having a flange (3.1) with an internal face provided with means (3.1.1) for retaining rotation with respect to the bottle (1).
Inside this pouring member (3), in this example of embodiment, is incorporated a chassis (2) that retains a valve (4) for preventing fraudulent refilling, as well as two balls (2.1) that increase the safety against fraudulent refilling provided by the valve (4).
The pouring member (3) is closed by a cap (5), to which it is connected by a thread (3.3, 5.1).
The internal closure assembly and the cap (5) are covered by a capsule (6) that can be separated into two portions or segments, an upper segment and a lower segment, the latter having the form of an external flange (6.5).
This flange is provided on its inner face with a peripheral lip (6.1) meant to be inserted in an external peripheral groove (3.2) of the pouring member (3).
This peripheral lip (6.1) does not have to be continuous; instead, as shown in figure 5, it may be discontinuous.
In this first example, as shown in the enlarged view of figure 5, the cross-section of the peripheral lip (6.1) has a small angle of inclination (α) in the lower face that facilitates the insertion of the capsule (6) on the pouring member (3).
However, this peripheral lip (6.1), working jointly with the peripheral groove (3.2) of the pouring member (3), is such that it provides retention in both axial senses (according to the position shown in the figures), both upward and downward.
As this lip (6.1) is inside the lower segment or external flange (6.5) of the capsule (6), after the upper segment of the capsule (6) is detached the external flange (6.5) is secured axially with respect to the bottle (1) by its attachment to the pouring member (3).
The upper part of the capsule (6) can be separated by two weakened lines (6.2) between which a band (6.3) is defined. The weakened lines (6.2) can for example be constituted by breakable bridges.
In this example of embodiment the two weakened lines (6.2) are parallel, defining a band (6.3) with a constant width that ends in a gripping tab (6.3.1) that makes it easier to start tearing the band (6.3).
Eliminating this band (6.3) involves only advancing in the peripheral sense until a full turn is completed.
After tearing, the presence of a connection segment between the band (6.3) and the end segment (6.6) of the upper segment allows that, after detaching the upper segment of the capsule (6), the band (6.3) remains connected to the end portion (6.6) of the upper segment, which in this case is essentially disc-shaped in view of the short length of the lateral segments left when eliminating the band (6.3).
In turn, the entire upper segment, understood as including the band (6.3), is separated from the flange (6.5).
Of the two weakened lines (6.2), the lower one is always above the attachment lip (6.1) so that the attachment of the flange (6.5) is always ensured, even after removing the upper segment of the capsule (6).
The end portion (6.6) of the upper segment, preferably disc-shaped, can be used for advertising purposes by printing or embossing, for example.
In a second example of embodiment, as shown in figure 6, the band (6.3) is not necessarily defined between two weakened lines (6.2) disposed in parallel, but instead an inclination is provided (6.2) in its initial segment that directs the final tearing of the band (6.3) towards the upper disc by an oblique segment (6.3.2), without the band (6.3) being detached from the upper portion of the capsule (6).
Although it is a cross sectional view the configuration of the band (6.3) can be seen equally from the inside.
In this second example the peripheral lip (6.1) inside the capsule (6) is continuous and remains according to the invention under the lower weakened line (6.2) that gives rise to the tearing band (6.3).
Figure 7 shows a third example of embodiment in which the weakened lines (6.2) are parallel to one another, but not continuous in the entire perimeter of the capsule (6), instead comprising at least two consecutive sectors; in the example shown in the figure there are 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), indicating for example the corresponding capsules, one of the ends of the adhesive tape could fall on the gripping tab (6.3.1), hindering the opening of the capsule (6). By including more than one gripping tab (6.3.1) in the band (6.3) the user is allowed access to another (6.3.1) that is not covered by said adhesive tape. Another advantage resulting from this third example of embodiment is that as the band (6.3) comprises several sectors, it is more obvious if the bottle has been opened, as it is more difficult to subsequently attempt to replace each sector in its initial position to conceal that the bottle was opened.
In this way, in the example of embodiment shown in figure 7 three sectors (6.3.3, 6.3.4, 6.3.5) are defined in the band (6.3) with a constant width, each sector (6.3.3, 6.3.4, 6.3.5) ending in a gripping tab (6.3.1) that makes it easier to start tearing each sector (6.3.3, 6.3.4, 6.3.5) of the band (6.3).
In addition, the end portion (6.6) of the capsule (6) is provided on the top with an orifice (6.6.1) which, in the embodiment shown, has a circular shape and is coaxial with the upper part of the cap (5), thereby revealing it so that the cap (5) can be seen.
Between at least one of the sectors (6.3.3, 6.3.4, 6.3.5) of the band (6.3) and the end portion (6.6) of the upper segment there is a connecting segment (6.4) that allows relating the band (6.3) and the aforementioned end portion (6.6).
In figures 8a, 8b and 8c the specific form of attachment has been established between the band (6.3) and the end portion (6.6) of the upper segment. This attachment is established by one or more ribs (6.7) (two in the example) with a very small thickness. The purpose of these ribs is to obtain a thickness greater than that of the wall on which they are placed. As the normal way to generate the weakened line is by an external cut, if the blade penetrates only the thickness of the wall the ribs (6.7) are not cut and maintain the relationship between the band (6.3) and the end portion (6.6) of the upper segment even after tearing.
Although the bottle (1) is not shown a design is considered that is adequate for application directly on the bottle (1). This bottle (1) incorporates a groove in which enters the attachment lip (6.1) internal to the flange (6.5). The pouring member in this case is integrated in the shape of the pouring mouth of the bottle.
