    Field of the Invention
    The invention relates to a cap for closing a container according to the preamble of claim 1 and a container with such a cap according to the preamble of claim 19.
    State of the art
    From the prior art in the field of plastic caps with a guarantee tape caps are known, which are held captive on the container and close the pouring opening. The holding function is also important insofar as legal regulations are to be expected, which oblige the closure of beverage bottles to be captively connected to the beverage bottle even when open.
    DE 24 30 775 A1 discloses such a captive closure cap. The cap consists of a screwable upper part and a lower collar, which engages behind a bead on the container mouth. The upper threaded part of the cap is connected to the lower collar via an easily tearable cylindrical tongue. This tongue extends over the entire circumference and is connected to the upper part and the lower collar via an upper or a lower row of connecting prongs. This cylindrical tongue is interrupted at one point on the circumference, so that it receives two ends, one of which is firmly connected to the screwable cap part and the other is firmly connected to the lower collar. The connecting tines of the upper and lower rows tear undefined when the cap is screwed on. As a result, after unscrewing, the teeth on the upper and lower rows are partially torn and partially still connected to the cap part and the lower collar. When pouring out liquid, the cap dangling from the container can prove to be annoying, since it can protrude into the liquid flow and cause liquid to spill.
    [0004] DE 93 18 243 U1 also discloses a captive closure cap for closing a container. After unscrewing the threaded part of the cap, it is held to the guarantee band with a tether. The tether is kept as short as possible so that it deforms strongly when unscrewed for the first time and therefore clearly indicates that it has already been unscrewed. However, the short tether has the disadvantage that the threaded part is in a disturbing position for the user when drinking from the container.
    Object of the invention
    It is therefore an object of the invention to prevent the disadvantages described above by creating a captive cap, which is not a hindrance with any use of the container to be closed.
    description
    The solution to the problem is achieved with a cap for closing a container by the features listed in the characterizing section of claim 1. Further developments and / or advantageous variants are the subject of the dependent claims.
    The invention is characterized in that the at least one first predetermined breaking element and the at least second predetermined breaking element have different tensile and tear strengths. When unscrewing the threaded part, the first and second predetermined breaking elements do not tear undefined, but the predetermined breaking element with the lower tensile strength tears when unscrewing. Therefore, when the threaded part is unscrewed, the first or the second predetermined breaking element is defined. The predetermined breaking element with the greater tensile strength, however, does not tear when the threaded part is unscrewed for the first time. The retaining band is therefore held on the threaded part or the guarantee band after unscrewing and is in a position near the neck of the container. In this position of the threaded part, it is held captive on the container and filling material can be poured out of the container without the threaded part being in the way of the pouring jet. To do this, the container or the threaded part must be rotated with the guarantee tape so that the threaded part is above the pouring jet.
    Should be drunk directly from the container, the threaded part may be too close to the face of the user and consequently bothers the user when drinking. Therefore, the predetermined breaking element with the greater tensile strength can be broken manually. As a result, the threaded part hangs on the retaining band and is at a distance from the container neck or the guarantee band. In this position of the threaded part you can easily drink from the container. In addition, the threaded part can be held by the hand, which also holds the container when drinking. Depending on how the container is used, the invention enables the threaded part to be brought into a position in which it does not hinder the pouring out of the filling material. In any case, the threaded part is held captive on the container. Regardless of the position of the threaded part, it is always indicated whether the container has already been opened. When the threaded part is unscrewed for the first time, the first or the second predetermined breaking element breaks and indicates that the container is no longer originally sealed.
    It is also conceivable that an internal thread is formed on the inside of the tether, which can cooperate with the external thread of the container neck. This embodiment causes the tether to be positioned by the external thread at a fixed distance from the threaded part, as long as the internal thread of the threaded part and the tether run in the external thread. As a result, the at least one second predetermined breaking element must tear when unscrewed, regardless of whether its tensile strength and the tensile strength of the at least one first predetermined breaking element are the same or whether its tensile strength is greater than the tensile strength of the at least one first predetermined breaking element. Consequently, in this embodiment of the invention, the retaining strap remains on the threaded part after unscrewing, regardless of the size of the tensile strength of the at least one first and second predetermined breaking element.
    In a particularly preferred embodiment of the invention, the first sol breaking element is a first web and the second predetermined breaking element is a second web. The webs can be easily adapted to a tensile strength to be achieved by their dimensioning, in particular by the dimensioning of their cross section. Walls with a corresponding wall thickness, which extend between the threaded part and the holding band or the holding band and the guarantee band, are also conceivable as predetermined breaking elements.
    Advantageously, a plurality of first webs is arranged between the open edge of the threaded part and the first edge of the tether. The first webs can be made with a certain tensile strength. An additional advantage is that the user does not have to tear down all of the first webs if the first webs have a higher tensile strength than the second webs. As a result, the tether can have a certain length by tearing off more or less first webs, which can be adapted to the use of the container.
    [0012] A plurality of second webs is expediently arranged between the guarantee band and the second edge of the retaining band. The advantages for the first webs stated in the last paragraph also apply to a plurality of second webs.
    In a preferred embodiment of the invention, the tensile strength of the first webs is the same and is greater than the tensile strength of the second webs. In this embodiment, the retaining strap remains on the threaded part when the threaded part is unscrewed. If necessary, the retaining strap can be separated from the open edge of the threaded part after unscrewing. This can also be done in stages if not all of the first webs are torn off.
    In a further preferred embodiment of the invention, the tensile strength of the second webs is the same and is greater than the tensile strength of the first webs. In this embodiment, the retaining band remains on the guarantee band when the threaded part is unscrewed. Since only the threaded part without the retaining strap has to overcome the height of the container neck, this can be unscrewed in a simplified manner. Since the retaining strap remains on the guarantee strap, its height does not have to be overcome when unscrewing.
    It proves to be advantageous if the first and second webs are arranged at regular intervals along the first and the second edge, respectively. The threaded part can be unscrewed with even force. In addition, the length of the tether can be selected in equal increments after unscrewing the threaded part.
    It has proven to be expedient if the first webs have the same cross-sectional area and the second webs have the same cross-sectional area. The tear-off force is therefore constant for the first webs or the second webs.
    The invention is preferably characterized in that the tether extends over a circular arc at an angle between 180 and 350 degrees and preferably at an angle between 270 and 350 degrees. The required length of the tether can be determined by the size of the circular arc angle. It goes without saying that, in addition to the choice of the arc angle, the diameter of the threaded part also has an influence on the length of the holding strap. The tether has an optimal length, for example, if it reaches up to the recessed grip of the container. This allows the user to hold the container and the threaded part with one hand at the same time. As a result, the threaded part does not dangle from the container when filling material is poured out or is drunk directly from the container.
    [0018] A gap is expediently provided between the first end and the second end of the tether. The first and second ends of the tether are separated from one another by the gap. The gap is advantageously as narrow as possible, so that the bottle neck area behind the retaining band is protected as extensively as possible. In addition, the narrowest possible gap leads to the longest possible holding strap. The gap is preferably between 0.5 mm and 5 mm wide.
    In a further particularly preferred embodiment of the invention, the position of the guarantee band relative to the annular projection of the container neck can be changed in the axial direction and in the circumferential direction. Because the guarantee band can be moved upwards in the axial direction, when the threaded part is unscrewed, it is pulled upwards until it strikes the annular projection of the container neck. When the threaded part is turned further, the weaker first or second webs are torn off. Then the threaded part has reached a sufficient height to be able to be folded away from the container neck. This necessary height is achieved without having to tear off the webs with greater tear strength. Because the guarantee band can be rotated in the circumferential direction, only a force is exerted on the webs in the axial direction and not in the circumferential direction. The tensile strength of the first and second webs can thus be designed for a defined axial force.
    Appropriately, a recess for receiving the tether is provided on the edge of the tether facing the tether. If the tether is designed short, the second end of the tether becomes correspondingly long so that a gap can be provided between the first and the second end. The entire length of the second end is connected to the guarantee band and is part of the guarantee band. As a result, a recess for the tether is formed on the guarantee band.
    In a further preferred embodiment of the invention, the first fixed connection between the first end of the tether and the open edge of the threaded part and / or the second fixed connection between the second end of the tether and the guarantee band is kinkable. As a result, the threaded part can be folded away from the neck of the container along the first or second end after unscrewing and is not in the way when filling material is poured out.
    It has proven to be useful if an inwardly projecting inner cone, e.g. in the form of a sealing cylinder or a sealing ring, which is designed to cooperate sealingly with the inner wall of the container neck in the closed position. The cap can therefore act as a so-called "cone sealer" and reliably seals the bottle neck.
    In a further preferred embodiment of the invention, the tether has a width between 3 mm and 7 mm and preferably a width between 4 mm and 5 mm. This dimensioning ensures that the tether does not tear off unintentionally, especially if the webs with the higher tensile strength are torn off. In addition, the closure cap does not become too high and can be sealed together with standardized container necks with an external thread.
    The invention is also characterized in that the closure cap is designed to cooperate with a standardized container neck with an external thread and an annular projection. The closure cap can therefore be placed on standardized container necks, in particular PET beverage bottles. Containers which are joined together with the closure cap according to the invention therefore do not have to be specially adapted to the closure cap.
    Advantageously, the cap is made of a plastic material, preferably HDPE (high density polyethylene) or PP (polypropylene). The closure cap can therefore be produced with standard plastic materials, from which known closure caps with a guarantee ring are also produced.
    In a further preferred embodiment of the invention, the threaded part, the inner cone, the guarantee band, the retaining band and the at least one first and second predetermined breaking element are made in one piece. As a result, the closure cap can be produced in an injection mold without the need for further processing steps in order to form the retaining band.
    Another aspect of the invention relates to a container comprising a container body, a container neck adjoining the container body, an external thread formed on the container neck and a closure cap according to the description above. Due to the fact that the at least one first predetermined breaking element and the at least second predetermined breaking element have different tensile strengths or tear strengths, or because an internal thread is formed on the inside of the retaining band, which can cooperate with the external thread of the container neck, all break when the cap is unscrewed from the container neck first or all second predetermined breaking element. The predetermined breaking elements on the retaining band opposite the broken first or second predetermined breaking elements remain intact when unscrewing and hold the retaining ring on the threaded part or on the guarantee tape. As a result, the threaded part is in a defined position relative to the container neck after unscrewing. In this position of the threaded part, the threaded part is not a hindrance when pouring a filling material. If the threaded part is to have an increased distance from the container neck, any number of unbroken predetermined breaking elements can be torn off manually. This can prevent the threaded part from being in the way of the user of the container, for example when drinking from the container, due to its short distance from the container neck.
    In a further preferred embodiment of the invention, a recess having a depth is provided on the container body, into which recess the closure cap can be received. As a result, the closure cap, when removed or unscrewed from the container neck, has a defined holder and prevents it from protruding into the pouring stream during use of the container and thereby interfering with the use of the container. Due to the possibility of being received or held in the recess, the closure cap is also not in the way when drinking directly from the container.
    It has proven to be advantageous if the closure cap is held in the recess by positive and / or non-positive connection when the closure cap is received in the recess. As a result, the closure cap can be inserted into the recess at any time when the container is used. After using the container, the cap can be removed from the recess and screwed back onto the container. The positive and / or non-positive connection enable a detachable connection between the recess and the closure cap. The frictional connection can be realized in that the inner dimensions of the recess are slightly smaller than the outer dimensions of the closure cap. As a result, there is an interference fit between the recess and the closure cap. It is also conceivable for the recess to have an elliptically shaped wall and for the cylindrically shaped closure cap to be held on the two secondary vertices of the elliptical recess. A positive connection can be realized by projections on the inner wall of the recess and / or on the outer wall of the closure cap, which cooperate with corresponding recesses on the outer wall of the closure cap or the inner wall of the recess. This allows the closure cap to snap into the recess. The positive connection can be released at any time by pulling the cap out of the recess.
    Advantageously, the distance of the recess from the guarantee band is at most as large as the length of the tether between the first and the second end. As a result, the closure cap reaches the recess and can be inserted into it without the retaining strap being too short.
    In a further preferred embodiment of the invention, the recess has a cylindrical shape with a bottom and a lateral surface defining the depth of the recess, the inside diameter of the recess essentially corresponding to the outside diameter of the closure cap. The recess therefore essentially has the negative shape of the closure cap. If there is a frictional connection between the closure cap and the recess, the inside diameter of the recess is slightly smaller than the outside diameter of the closure cap and accordingly there is an interference fit between the recess and the closure cap.
    Advantageously, the depth of the recess is ≤ the height of the closure cap. As a result, the closure cap protrudes from the recess and can be easily attacked for removal from the recess in the region of the jacket which projects beyond the recess. It would also be conceivable for the closure cap to be pulled out of the recess on the retaining strap.

    In Figures 1 to 3, a closure cap is shown, which is generally designated by the reference numeral 11. The closure cap 11 is held captively on a container 13, in particular on a bottle 13. The closure cap 11 comprises a cylindrical threaded part 15, a guarantee band 17 and a retaining band 19.
    The threaded part 15 comprises a bottom 21 and a first cylindrical jacket 23 with an open edge 25. An internal thread 27 is formed on the inside of the jacket 23. The container 13 comprises a container body 28 and a container neck 29 adjoining the container body 28. The container neck 29 is designed as a second cylindrical jacket. An external thread 31 is formed on the container neck 29 and cooperates with the internal thread 27. As a result, the threaded part 15 can be screwed onto the container neck 29 and unscrewed from it. The closure cap 11 closes the pouring opening 32, which is provided within the container neck 29.
    The guarantee band 17 is positively held on the container neck 13. For this purpose, an annular projection is formed on the outside of the container neck 29, which can be gripped by projections formed on the inside of the guarantee band 17 (not shown in the figures). The guarantee band 17 can be rotated relative to the container neck 29.
    The tether 19 has a first end 33 and a second end 35. The first end 33 is fixed to the open edge 25. The second end 35 is firmly connected to the guarantee band 17. As a result, the closure cap 11 is held captively on the container 13. Furthermore, the tether has a first edge 37 and a second edge 39. The first edge 37 is connected to the open edge 25 by a plurality of first predetermined breaking bars 41 and the second edge 39 is detachably connected to the guarantee tape 17 by a plurality of second predetermined breaking bars 43. It is preferred if the holding band 19 has a width between 4 mm and 5 mm so that it is sufficiently stable and that it can be pulled off manually from the threaded part 15 or the guarantee band 17.
    The first and second predetermined breaking webs 41, 43 have different tensile strengths. I.e. the first predetermined breaking webs 41 can have a greater tensile strength than the second predetermined breaking webs 43 or the second predetermined breaking webs 43 can have a greater tensile strength than the first predetermined breaking webs 41. The first and the second predetermined breaking webs 41, 43 are preferably arranged or formed at uniform intervals on the first edge 37 and on the second edge 39, respectively. It is also preferred if the cross-sectional areas of the first predetermined breaking webs 41 are of the same size and if the cross-sectional areas of the second predetermined breaking webs 43 are of the same size.
    Characterized in that the first and the second predetermined breaking webs 41, 43 have different tensile and tear strengths, either unscrew the first predetermined breaking webs 41 or the second predetermined breaking webs 43 when the threaded part 15 is unscrewed. After the threaded part 15 has been unscrewed, the retaining band 19 therefore remains on the threaded part 15 or on the guarantee band 17. The guarantee band 17 can be displaced in the axial direction by a few millimeters relative to the annular projection of the container neck. As a result, the retaining band 19 can remain completely on the threaded part 15 or on the guarantee band 17, since the retaining band 19 does not have to provide a “height” between the threaded part 15 and the guarantee band 17 when the threaded part 15 is unscrewed.
    FIG. 2 shows the embodiment in which the second predetermined breaking webs 43 have a lower tensile strength than the first predetermined breaking webs 41. As a result, the second predetermined breaking webs 43 tear when unscrewing and the retaining band 19 remains on the threaded part 15 when unscrewing. The connection between the second end 35 and the guarantee band can preferably be bent, as a result of which the threaded part 15 can be bent away from the container neck 29. The position of the threaded part as shown in Figure 2 is optimal for pouring liquid from the bottle 13 into a glass. The threaded part 15 is not in the way of the liquid jet.
    Should be drunk directly from the bottle 13, the threaded part 15 can interfere with drinking according to the position in Figure 2. Then the retaining band 19 can also be pulled off the threaded part 15 by tearing off the first predetermined breaking webs 41. This leads to a position of the threaded part 15 as shown in FIG. 3. The threaded part 15 is still held on the bottle 13, but is no longer in the way of the user when drinking from the bottle 13. The threaded part 15 can be held together with the bottle 13 on the recess 45 while drinking. Only some of the first predetermined breaking webs 41 can also be torn off in order to obtain a suitable length of the holding strap 19. It is also conceivable that when the threaded part 15 is unscrewed, the retaining band 19 remains on the guarantee band 17. Then it is preferred if the connection between the first end 33 and the guarantee band 17 can be kinked.
    The length of the tether 19 can be determined by the angle of the circular arc, the length of which corresponds to the length of the tether 19. The circular arc angle is preferably between 270 and 350 degrees. The retaining band 19 has the correct length at this angle so that the threaded part 15 can be held together with the bottle 13 with one hand while drinking from the bottle 13. It goes without saying that the length of the tether also depends on the diameter of the closure cap 11. It can therefore make sense to reduce the circular arc angle for larger diameters, for example sealing caps with an outer diameter of 38 mm, so that the retaining band 19 has the desired length and the captive threaded part 15 is not in the way when the container 13 is used.
    A gap 47 is provided on the closure cap 11 between the first and the second end 33, 35 of the tether 19, so that the tether 19 receives a first and a second end 33, 35.
    The cap 11 is made of a plastic. PP and HDPE are among the preferred plastics.
    In the figures 4 to 6, the container 13 is shown in an embodiment in which a recess 49 is provided on the container body 28. The recess 49 has a cylindrical shape with a bottom 51 and a lateral surface 53. The recess 49 is preferably provided or formed in the shoulder region 55 of the container. The shoulder region 55 forms the transition between the cylindrical part 57 of the container body 28 and the container neck 29.
    In Figures 5 and 6, the cap 11 is shown when it is received in the recess 49 or is inserted into the recess 49. So that the tether 19 is not in the way, the closure cap 11 must be inserted into the recess 49 with its side facing away from the tether. The closure cap 11 must be held in the recess 49 so that it does not fall out of the recess 49 when the container 13 is used. Therefore, the closure cap 11, in particular the outer wall 59 thereof, is held by a force fit and / or a form fit.
    A positive connection between the outer wall 59 and the outer surface 53 can be achieved most simply by the outer diameter of the closure cap 11 being slightly larger than the inner diameter of the recess 49. An interference fit is thereby achieved and the closure cap 11 is jammed in the recess.
    A form fit can be achieved by 59 projections or depressions are formed on the outer wall, which cooperate with corresponding depressions or projections, formed on the lateral surface 53. As a result, the closure cap 11 can snap into the recess 49.
    The recess 49 is positioned on the container 13 such that the closure cap 11 reaches the recess 49, although the closure cap 11 hangs on the tether 19. The distance of the recess 49, in particular of the region of the recess 49 which is closest to the container neck 29, must therefore be selected such that it is at most as long as the length of the holding strap 19 between the first end 33 and the second end 35 .
    It is preferred if the depth 61 of the recess 49 is less than or equal to the height 63 of the closure cap 11. These coordinated dimensions of the closure cap 11 and the recess 49 make it possible for the closure cap 11 to be gripped at its area protruding from the recess 49 and to be pulled out of the recess 49 in order to close the container 11 again.
    The recess 49 enables the closure cap 11, which is removed from the container neck 29, to be secured to the container 13 so that it does not interfere with drinking from the container 11 or when pouring out the container contents.
