Definitions
- the present invention relates to plastic containers, in particular plastic bottles for natural mineral water, or plastic bottles for sparkling mineral water and also for other beverages.
- Plastic bottles are normally provided with a screw cap, or capsule, which is engaged to the bottle and which has a tamper evident seal or security band that is broken when the bottle is opened for the first time and provides the consumer with a guarantee of the integrity of the bottle content at the time of purchase.
- Plastic bottles of this type normally have a threaded neck and, between the thread and the body of the bottle, two perimeter collars or annular ridges, the one used to couple the tamper evident seal and the other to handle the bottles in the filling plants.
- EP-A-2207722 describes a plastic bottle wherein the neck of the bottle has only one perimeter collar or annular ridge used both to engage the bottle with handling and conveying members inside the filling plant, and to constrain the tamper evident seal. To allow handling of the bottle, between the threaded neck of the bottle and the annular ridge there is provided an annular groove or recess in which the mechanical handling members engage.
- WO-A-2009/146567 describes a cap with tamper evident seal for a bottle, said cap comprising a lateral wall and an internal thread formed on an internal surface of the lateral wall.
- the lateral wall of the cap comprises a security element in the form of a tab that cooperates with the thread of the bottle, so as to be irreversibly altered when the screw cap is removed from the bottle.
- the bottle is provided with a collar placed between the body of the bottle and the thread.
- the invention provides for a container, typically a plastic bottle, for example and in particular for water or other beverages, comprising: a body; a substantially cylindrically shaped end portion or neck, forming an opening mouth; a thread, formed on an external surface of said end portion, for engaging a closing cap. Between the body of the container and the end portion or neck there is provided a guiding shoulder to guide the container in the packaging plants.
- a container typically a plastic bottle, for example and in particular for water or other beverages, comprising: a body; a substantially cylindrically shaped end portion or neck, forming an opening mouth; a thread, formed on an external surface of said end portion, for engaging a closing cap.
- a guiding shoulder to guide the container in the packaging plants.
- the end portion or neck of the container extends from the mouth of the container up to said guiding shoulder.
- the shoulder has an external diameter equal to the diameter of the external surface of the end portion or neck of the container and an internal diameter smaller than the external diameter and equal to the minimum diameter of a shoulder connecting the end portion or neck to the body of the container.
- the thread has at least one stop surface for cooperating with a security element of a closing cap of the container.
- the invention relates to a system comprising a screw cap and a container, typically a bottle, as described above.
- the invention relates to a preform for producing a plastic container, typically a bottle, as described above.
- the preform comprises a main body and a substantially cylindrical end portion or neck, having a radial dimension greater than the radial dimension of the body of the preform (where radial dimension of the body of the preform is preferably intended as the minimum radial dimension of this body, if it has a variable dimension) and having a thread formed on an external cylindrical surface of the end portion or neck.
- a shoulder intended to form a guiding surface of the container, said shoulder extending radially inward from the substantially cylindrical surface of the end part or neck of the preform.
- the invention provides for a screw cap for a container comprising a lateral wall and an internal thread formed on an internal surface of the lateral wall, characterized in that the lateral wall comprises a security element configured to be irreversibly altered when the screw cap is removed from the container.
- the security element is permanently altered, for example deformed or broken, when the cap is unscrewed, as a result of interference with the external thread of the container, for example a bottle.
- a tamper evident seal is thus obtained without the need to use an additional band on the cap and related collars on the bottle.
- a reduction of the length or height of the end portion or neck of the bottle of around 6-7 mm, typically around 6.5 mm, is also obtained. In this area, the thickness of the plastic material is around 1 mm. This results in a substantial saving of plastic material, with considerable reduction of costs and environmental impact.

- FIG. 4 shows an enlargement of the neck 1 A of the bottle without the cap 3 .
- an external thread 5 that can comprise one or more threads 5 A.
- Each thread can have one or more breaks 5 B.
- each thread 5 A is discontinuous and broken in one or more points or break areas 5 B. On the one hand this enables a reduction in the plastic material required to produce the bottle and on the other it facilitates operation of the security cap, as will be explained below.
- the bottle 1 has no collar between neck 1 A and body 1 B of the bottle 1 . It has a shoulder 1 S that joins the main body 1 B of the bottle to the upper part or neck 1 A, on the external cylindrical surface 1 Z of which, having an external diameter DM, the thread 5 is formed.
- the cylindrical portion forming the neck 1 A of the bottle ends at the bottom with an undercut or shoulder 1 X, below which the shoulder 1 S of the bottle is connected.
- the undercut or shoulder 1 X forms an annular supporting surface, with a major diameter equal to the diameter DM of the cylindrical portion 1 A forming the neck of the bottle and a minor diameter indicated with Dm.
- the annular shoulder of radial dimension (DM ⁇ Dm)/2 thus formed is sufficient to provide a guiding surface for handling the bottle in the filling plants.
- the shoulder 1 X formed starting from the external cylindrical surface of the end portion or neck 1 A toward the axis of the bottle 1 in substance replaces the collar normally provided on prior art bottles, which projects radially outward with respect to the cylindrical surface on which the thread of the bottle is produced.
- the shape of the bottle 1 shown in FIG. 4 enables a reduction in the quantity of plastic material required to produce the bottle with respect to conventional solutions.
- the collar that is usually provided between the thread of the neck of the bottle and the body of the bottle is eliminated.
- the quantity of plastic required to form it is also eliminated.
- the axial length of the neck of the bottle can be reduced.
- the axial length of the portion of neck 1 A of the bottle of FIG. 4 (between thread 5 and shoulder 1 S of the bottle) is substantially less (by several millimeters) than the neck of conventional bottles, which are provided with at least one and, in some cases, with two collars.
- the diameter DM and the diameter Dm can be such as to form a shoulder 1 X with a radial dimension of around 3-4 mm, for example around 3.5 mm.
- the diameter DM can be in the order of 22-23 mm and the diameter Dm can be in the order of 15-16 mm.
- the height of the cylindrical portion 1 A forming the neck of the bottle can be in the order of 12-20 mm, for example around 15 mm.
- This different shape of the upper part of the bottle implies, in conventional bottles for mineral water or beverages, a reduction in weight of around 2-2.5 g per bottle.
- Modern bottling plants produce several tens of thousands of bottles per hour and therefore a reduction of around 2 grams of plastic on each bottle implies a very large saving of plastic material, with economic advantages for the manufacturer and a reduction of environmental impact.
- modification of the upper part of the bottle described above implies a saving of around 160-176 kg/hour of plastic, which in a continuous processing plant implies a daily saving of 3840-4224 kg/day of plastic and consequently of 1400-1542 tons/year of plastic.
- cost in the case of PET, which currently costs 1,180 Euro per ton, the annual saving is of around 1,650,000-1,820,000 Euro.

Abstract
There is described a container (1) with a thread (5) for a screw closing cap (3). The container has a neck (1A) with a lower shoulder (1X) that extends from the external surface (1Z) of the neck, on which the thread (5) is formed toward the inside.
Description
- The present invention relates to plastic containers, in particular plastic bottles for natural mineral water, or plastic bottles for sparkling mineral water and also for other beverages.
- The use of plastic bottles for packaging mineral water or other beverages is very widespread. Plastic bottles are normally provided with a screw cap, or capsule, which is engaged to the bottle and which has a tamper evident seal or security band that is broken when the bottle is opened for the first time and provides the consumer with a guarantee of the integrity of the bottle content at the time of purchase.
- Modern large bottling plants fill tens of thousands of bottles per day, and in some cases hundreds of thousands of bottles and consequently they consume a large number of this type of container. There is constant search for new ways of reducing the weight of each bottle and of each cap, firstly to reduce production costs and secondly to also reduce the environmental impact of this type of packaging, considered that not all plastic bottles are recycled.
- Plastic bottles of this type normally have a threaded neck and, between the thread and the body of the bottle, two perimeter collars or annular ridges, the one used to couple the tamper evident seal and the other to handle the bottles in the filling plants.
- EP-A-2207722 describes a plastic bottle wherein the neck of the bottle has only one perimeter collar or annular ridge used both to engage the bottle with handling and conveying members inside the filling plant, and to constrain the tamper evident seal. To allow handling of the bottle, between the threaded neck of the bottle and the annular ridge there is provided an annular groove or recess in which the mechanical handling members engage.
- The use of a single perimeter collar or annular ridge, in place of the conventional conformation with double collar, enables the weight of each bottle to be reduced by a few grams and consequently the quantity of plastic used each year by the packaging plant to be reduced by many tons.
- WO-A-2009/146567 describes a cap with tamper evident seal for a bottle, said cap comprising a lateral wall and an internal thread formed on an internal surface of the lateral wall. The lateral wall of the cap comprises a security element in the form of a tab that cooperates with the thread of the bottle, so as to be irreversibly altered when the screw cap is removed from the bottle. The bottle is provided with a collar placed between the body of the bottle and the thread.
- These known systems have reduced the quantity of plastic used to produce bottles and caps. However, there is still a margin for improving this aspect and further reducing the quantity of plastic material required to produce each bottle.
- The invention provides for a container, typically a plastic bottle, for example and in particular for water or other beverages, comprising: a body; a substantially cylindrically shaped end portion or neck, forming an opening mouth; a thread, formed on an external surface of said end portion, for engaging a closing cap. Between the body of the container and the end portion or neck there is provided a guiding shoulder to guide the container in the packaging plants.
- In this way the collar or annular ridge normally provided on the neck of the container, between the thread and the body of the container, is omitted. This results in a reduction of the plastic material required to produce the container, both because the neck can be shorter, and because the plastic material forming the projecting collar is no longer necessary.
- Advantageously, the end portion or neck of the container extends from the mouth of the container up to said guiding shoulder. Preferably, the shoulder has an external diameter equal to the diameter of the external surface of the end portion or neck of the container and an internal diameter smaller than the external diameter and equal to the minimum diameter of a shoulder connecting the end portion or neck to the body of the container.
- According to some embodiments, the thread has at least one stop surface for cooperating with a security element of a closing cap of the container.
- According to another aspect, the invention relates to a system comprising a screw cap and a container, typically a bottle, as described above.
- According to yet another aspect, the invention relates to a preform for producing a plastic container, typically a bottle, as described above. In some embodiments, the preform comprises a main body and a substantially cylindrical end portion or neck, having a radial dimension greater than the radial dimension of the body of the preform (where radial dimension of the body of the preform is preferably intended as the minimum radial dimension of this body, if it has a variable dimension) and having a thread formed on an external cylindrical surface of the end portion or neck. Between the end portion or neck and the body of the preform there is provided a shoulder intended to form a guiding surface of the container, said shoulder extending radially inward from the substantially cylindrical surface of the end part or neck of the preform.
- According to a different aspect, the invention provides for a screw cap for a container comprising a lateral wall and an internal thread formed on an internal surface of the lateral wall, characterized in that the lateral wall comprises a security element configured to be irreversibly altered when the screw cap is removed from the container. The security element is permanently altered, for example deformed or broken, when the cap is unscrewed, as a result of interference with the external thread of the container, for example a bottle. A tamper evident seal is thus obtained without the need to use an additional band on the cap and related collars on the bottle. A reduction of the length or height of the end portion or neck of the bottle of around 6-7 mm, typically around 6.5 mm, is also obtained. In this area, the thickness of the plastic material is around 1 mm. This results in a substantial saving of plastic material, with considerable reduction of costs and environmental impact.
- In advantageous embodiments of the cap, the security element is arranged in an intermediate position of the lateral wall, between an end edge and a front wall of the cap. It can have a portion projecting from the internal surface of the lateral wall toward a rotation axis of the cap. For example, the security element can comprise a tab projecting toward the inside of the .cap. In advantageous embodiments, the tab extends tangentially and preferably with an inclination corresponding to the inclination of the thread. The tab can be housed in a cutout or slit provided in the lateral wall of the cap and can be fastened at a proximal end thereof to the wall, while the distal end can project toward the internal volume of the cap, so as to interfere with the external thread of the bottle or other container.

The same reference numbers in different drawings identify the same or similar elements. Additionally, the drawings are not necessarily drawn to scale. Also, the following detailed description does not limit the invention. Instead, the scope of the invention is defined by the appended claims.
- Reference throughout the specification to “one embodiment” or “an embodiment” or “some embodiments” means that the particular feature, structure or characteristic described in connection with an embodiment is included in at least one embodiment of the subject matter disclosed. Thus, the appearance of the phrase “in one embodiment” or “in an embodiment” or “in some embodiments” in various places throughout the specification is not necessarily referring to the same embodiment(s). Further, the particular features, structures or characteristics may be combined in any suitable manner in one or more embodiments.
- Hereinafter, specific reference will be made to an embodiment wherein the plastic container is a bottle, for example a bottle for beverages, such as mineral water or the like. However, it must be understood that the concept on which the invention is based can also be embodied in other types of plastic containers with similar requirements and technical-functional characteristics similar to those of bottles for water and/or beverages.
- In
FIG. 1 a plastic bottle for water and/or beverages of other type is indicated with 1, while the cap of the bottle, in the closed arrangement, is indicated with 3. The neck or upper end portion of thebottle 1 is indicated with 1A. The body of the bottle is indicated with 1B and the shoulder betweenneck 1A andbody 1B is indicated with 1S. -
FIG. 4 shows an enlargement of theneck 1A of the bottle without thecap 3. Around theneck 1A of thebottle 1, below themouth 1C and on the externalcylindrical surface 1Z of theneck 1A, there is formed anexternal thread 5 that can comprise one ormore threads 5A. Each thread can have one ormore breaks 5B. In fact, in some embodiments eachthread 5A is discontinuous and broken in one or more points or breakareas 5B. On the one hand this enables a reduction in the plastic material required to produce the bottle and on the other it facilitates operation of the security cap, as will be explained below. - More in particular, the
bottle 1 has no collar betweenneck 1A andbody 1B of thebottle 1. It has ashoulder 1S that joins themain body 1B of the bottle to the upper part orneck 1A, on the externalcylindrical surface 1Z of which, having an external diameter DM, thethread 5 is formed. - The cylindrical portion forming the
neck 1A of the bottle ends at the bottom with an undercut orshoulder 1X, below which theshoulder 1S of the bottle is connected. The undercut or shoulder 1X forms an annular supporting surface, with a major diameter equal to the diameter DM of thecylindrical portion 1A forming the neck of the bottle and a minor diameter indicated with Dm. The annular shoulder of radial dimension (DM−Dm)/2 thus formed is sufficient to provide a guiding surface for handling the bottle in the filling plants. Theshoulder 1X formed starting from the external cylindrical surface of the end portion orneck 1A toward the axis of thebottle 1 in substance replaces the collar normally provided on prior art bottles, which projects radially outward with respect to the cylindrical surface on which the thread of the bottle is produced. - The shape of the
bottle 1 shown inFIG. 4 enables a reduction in the quantity of plastic material required to produce the bottle with respect to conventional solutions. In fact, on the one hand the collar that is usually provided between the thread of the neck of the bottle and the body of the bottle is eliminated. By eliminating the collar, the quantity of plastic required to form it is also eliminated. Moreover, as there is no collar, the axial length of the neck of the bottle can be reduced. The axial length of the portion ofneck 1A of the bottle ofFIG. 4 (betweenthread 5 andshoulder 1S of the bottle) is substantially less (by several millimeters) than the neck of conventional bottles, which are provided with at least one and, in some cases, with two collars. - In some embodiments, the diameter DM and the diameter Dm can be such as to form a
shoulder 1X with a radial dimension of around 3-4 mm, for example around 3.5 mm. For example, the diameter DM can be in the order of 22-23 mm and the diameter Dm can be in the order of 15-16 mm. The height of thecylindrical portion 1A forming the neck of the bottle can be in the order of 12-20 mm, for example around 15 mm. - This different shape of the upper part of the bottle implies, in conventional bottles for mineral water or beverages, a reduction in weight of around 2-2.5 g per bottle. Modern bottling plants produce several tens of thousands of bottles per hour and therefore a reduction of around 2 grams of plastic on each bottle implies a very large saving of plastic material, with economic advantages for the manufacturer and a reduction of environmental impact. For example, in a bottling plant that produces 80,000 bottles per hour, modification of the upper part of the bottle described above implies a saving of around 160-176 kg/hour of plastic, which in a continuous processing plant implies a daily saving of 3840-4224 kg/day of plastic and consequently of 1400-1542 tons/year of plastic. This leads to a corresponding reduction of the quantity of plastic disposed of as waste and/or recycled. With regard to cost, in the case of PET, which currently costs 1,180 Euro per ton, the annual saving is of around 1,650,000-1,820,000 Euro.
- The
cap 3 can generally have an axial-symmetrical shape, with axis A-A. Thecap 3 can comprise alateral wall 7 extending from an end edge orlower edge 9 to a front wall orupper wall 11 of thecap 3. Thelateral wall 7 has anexternal surface 7A and aninternal surface 7B. Along theinternal surface 7B aninternal thread 13 is provided, which comprises one ormore threads 13A. Theinternal thread 13 is configured to cooperate with theexternal thread 5 provided on theneck 1A of thebottle 1. - The height H of the
cap 1, i.e. the dimension in axial direction of thecap 3, can advantageously be such that, when thecap 3 is screwed onto thebottle 1, theedge 9 of the cap is approximately positioned at theshoulder 1X formed between thecylindrical portion 1A and theshoulder 1S of thebottle 1. - Along the extension of the
lateral wall 7, i.e. between theedge 9 and thefront wall 11, in thewall 7 there is housed a security element, or tamper evident element, i.e. a member designed to interact with thebottle 1 and indicate whether the bottle has been opened. The security element replaces the conventional security band or tamper evident band provided on prior art caps. In the drawing, the security element is indicated as a whole with 15. In some embodiments, the security or tamperevident element 15 comprises atab 17 and a cutout or slit 19 formed in thelateral wall 7 and extending for the whole of the thickness thereof, i.e. open on both the internal 7B and external 7A surfaces of thelateral wall 7. - In some embodiments, the
tab 17 and the slit orcutout 19 are oriented approximately tangentially, i.e. they have a larger dimension in the circumferential or perimeter direction of thewall 7 and a smaller dimension in the axial direction. - In advantageous embodiments, the
tab 17 and the slit orgroove 19 are oriented approximately in the direction of thethreads 13A of theinternal thread 13. Advantageously, thetab 17 and the respective cutout or slit 19 that houses it are arranged in the groove between twoadjacent threads 13A, as can be seen in particular inFIGS. 2 and 3 . When thecap 3 is screwed onto the neck of thebottle 1, thetab 17 and the related cutout or slit 19 are thus arranged at athread 5A of theexternal thread 5 of the bottle. - In practice, on the internal face of the cap, the
tab 17 can be fully housed in the slit orcutout 19, with the exception of adistal end 17A. In substance, thetab 17 is set back with respect to theinternal surface 7B or flush there with, except for thedistal end 17A. The opposite end of thetab 17, labled with 17B and hereinafter namedproximal end 17B, is fastened to the material forming thewall 7 of thecap 3. Between thedistal end 17A and theproximal end 17B of thetab 17 there extends the main body of thetab 17. The thickness of the body of the tab can correspond substantially to the thickness of thelateral wall 7. - Therefore, in practice in some embodiments the
tab 17 is constituted by an elongated portion of the same material forming thewall 7 of thecap 3, joined to thewall 7 at theproximal end 17B, while the remaining part is separated from thewall 7, but housed in the thickness of thelateral wall 7 inside the slit orcutout 19. - The
distal end 17A of thetab 17 is generally shaped so as to interfere with the neck of thebottle 1 when it is unscrewed, so as to cause a permanent visible alteration of thetab 17. The shape of thedistal end 17A is also such as to enable initial screwing of thecap 3 onto thebottle 1 without deformation or permanent alteration of thetab 17. In this way thetab 17 acts as a security or tamper evident element that indicates if the bottle has been opened, enabling the user to check whether the bottle is integral, for example at the time of purchase. - In some embodiments, along the main body of the
tab 17, between thedistal end 17A and theproximal end 17B, anincision 17C is provided that forms a preferential bending or breaking point, for purposes that will be explained below. In some embodiments, a second preferential bending or breaking point can be provided at theproximal end 17B of thetab 17, as can be seen in particular inFIGS. 6 and 7 . Theincision 17C can be formed on the external surface of the tab, as shown in the drawing, or on the internal surface thereof. Likewise, an internal or external incision can also be provided at theproximal end 17B of the tab, as shown in the drawing. It would also be possible for both an internal and an external incision to be provided. - In some embodiments, the
distal end 17A of thetab 17 has anend surface 17D that extends toward the inside of thecap 3, i.e. toward the axis A-A of said cap, beyond theinternal surface 7B of thelateral wall 7. Theend surface 17D can be radial, or inclined with respect to the radial direction, as shown in the drawing. - In advantageous embodiments, the innermost corner of the
end surface 17D is joined to the body of thetab 17 by means of asecond surface 17E facing the inside of thecap 3. In practical embodiments, theconnection surface 17E can be curved, or flat, as shown by way of example inFIGS. 6 and 7 . When the cap is integral (FIG. 6 ) thesurface 17E is more inclined than thesurface 17D with respect to the radial direction. The connection corner between the twosurfaces cap 3, i.e. beyond theinternal surface 7B of thelateral wall 7. - When the cap is screwed onto the bottle, as can be seen in
FIG. 6 , thedistal end 17A of thetab 17 projects toward theneck 1A of thebottle 1 and is inserted in one of thebreaks 5B of theexternal thread 5. - In advantageous embodiments, at least at some of the
breaks 5B, thecorresponding thread 5A has astop surface 5C inclined with respect to the radial direction and forming an undercut. As can be seen in particular inFIG. 6 , the orientation of thefront surface 17D of thetab 17 and the orientation of thestop surface 5C of thethread 5A, at thebreak 5B of which thedistal end 17A of thetab 17 is positioned, are such that when the cap is unscrewed, according to the arrow F (FIGS. 6 , 7), thedistal end 17A of thetab 17 abuts in the undercut formed by thestop surface 5C and the rotation of the cap causes outward deformation (arrow f17,FIG. 7 ) of thetab 17. Deformation is facilitated by the facilitated deformation orbreaking point 17C in the central area of the body of the tab and by the facilitated deformation or breaking point at theproximal end 17B of thetab 17, where this joins to thewall 7 of thecap 3. - Rotation of the
cap 3 in the direction of unscrewing (arrow F), causes therefore a permanent deformation or breakage of the tab. This condition (FIG. 7 ) is easily detectable from the outside of the bottle and of the cap. Thetab 17 thus forms a security or tamper evident element that replaces the conventional tamper evident band. The user is able to determine the integrity of the bottle by observing or touching thetab 17. - The function of security or tamper evident element is obtained without the need to manufacture a tamper evident band along the
lower edge 1A of the cap and therefore reducing the quantity of material required to produce the cap. The need for a collar on the bottle, which in prior art bottles has the sole function of cooperating with the tamper evident band, is also eliminated. This also contributes to limiting the quantity of plastic used to produce the bottles. -
FIG. 8 schematically shows a preform used to produce thebottle 1. The preform has abody 1P, intended to form the body of the bottle, the preformedportion 5P with theexternal thread 5 and theshoulder 1X. The preformedportion 5P constitutes an end portion orneck 1A, which corresponds to the end portion orneck 1A of thebottle 1. Theexternal surface 1Z of the end portion orneck 1A is substantially cylindrical. Thethread 5 projects radially outward from thecylindrical surface 1Z, of the end portion orneck 1A, while theshoulder 1X extends radially inward from the lower edge of the externalcylindrical surface 1Z, with diameter DM, until reaching the minimum diameter Dm. - In some embodiments, under the
shoulder 1X the preform has a shape that increases in diameter, to facilitate subsequent molding of the finished bottle. -
FIG. 9 schematically shows an improved preform for producing a bottle of the type described above. Also in this embodiment, the preform has abody 1P, destined to form the body of the bottle, the preformedportion 5P with theexternal thread 5 and theshoulder 1X. Thebody 1P preferably has a constant external diameter from theshoulder 1X to the bottom of the preform, indicated with 1F. This external diameter is equal to the minor diameter Dm of theshoulder 1X of thebottle 1. - In some embodiments the security system of the present invention can be made more efficient by the presence of a breakable constraining element between the
tab 17 and thewall 7 of the cap. This additional element is illustrated by way of example in a modified embodiment, shown inFIGS. 10 and 11 , which show sections similar to those ofFIGS. 6 and 7 . The same numbers indicate parts equal or equivalent to those described above. InFIGS. 10 and 11 ,reference 17F indicates a breakable constraining element, which joins thetab 17 to the edge of the cutout or slit 19 formed in thewall 7. - In some embodiments, the
element 17F has the form of a bridge and can be formed at the distal end of thetab 17. - When the
cap 3 is unscrewed, the deformation of thetab 17 causes tearing of thebridge 17F. This provides the user with an even clearer indication of the fact that the container is not integral. - In some embodiments, the
bridge 17F or other breakable element can be placed in a different position, for example along the lateral extension of thetab 17, rather than at the distal end thereof. It would also be possible to provide more than one breakable element, for example more than onebridge 17F, in various points of thetab 17. - The embodiments described above and illustrated in the drawings have been discussed in detail as examples of embodiment of the invention. Those skilled in the art will understand that many modifications, variants, additions and omissions are possible, without departing from the principles, concepts and teachings of the present invention as defined in the appended claims. Therefore, the scope of the invention must be determined purely on the basis of the broadest interpretation of the appended claims, comprising these modifications, variants, additions and omissions therein. The terms “comprise” and its derivatives do not exclude the presence of further elements or steps besides those specifically indicated in a given claim. The term “a” or “an” preceding an element, means or characteristic of a claim does not exclude the presence of a plurality of these elements, means or characteristics.
