Description
Technical Field
The present invention relates to a closure cap for closing a container according to the preamble of claim 1 and a container with such a closure cap according to the preamble of claim 20.
Prior Art
Closures which are captively held on a container and close its pouring opening are known from the prior art in the field of plastic closures with tamper-evident rings. The retention function is also important because legal regulations are to be expected under which the closure of the beverage bottle must be captively connected to the beverage bottle even when in the open state.
A container closure having a threaded portion and a tamper-evident ring is known from the prior art. The open edge of the threaded portion is connected to the tamper-evident ring by a retaining strip, whereby the threaded portion is captively retained on the tamper-evident ring or container even after unscrewing from the container. However, the unscrewed threaded portion is a hindrance to the user when the product is poured and drunk from the bottle. Furthermore, the retaining strip can be easily torn off when the bottle is opened, so that the threaded portion is no longer retained on the tamper-evident ring.
CH 715953A2 and CH 716074A1 disclose closures having a first retaining strip and a second retaining strip between the tamper resistant ring and the threaded portion. Two retaining strips are necessary to hold the threaded portion in a stable and swing-free manner in the open position on the beverage bottle. The sizing and design of the two retaining strips is complex in terms of the smoothing function.
Object of the invention
Starting from the disadvantages of the prior art, the object of the invention is to improve a captive closure in such a way that it no longer has these disadvantages.
Description of the invention
This object is achieved by a closure cap for closing a pouring opening of a container of the character-ized in the characterizing part of claim 1. Improvements and/or advantageous alternative embodiments form the subject matter of the dependent claims.
Preferably, the invention is characterized in that a single retaining strip is provided, which in the unopened state is arranged between the threaded portion and the tamper-proof ring and extends along the circumference of the tamper-proof ring in an arc having a first angle ranging from 30 degrees to 50 degrees, wherein a third predetermined breaking element is arranged in a portion of the threaded portion in which the threaded portion and the tamper-proof ring are located directly on top of each other. This angular dimension enables the formation of a relatively short retaining strip which has a restoring or spring force and which is capable of pressing the threaded portion against the container neck in the open state. Thus, the length of the retaining strip enables a stable open position of the threaded component to be achieved with a single retaining strip. Both the retaining ring and the tamper-evident ring are held on the threaded portion by a third predetermined breaking element, so that an initial closure of the closure cap can be visually clearly identified by an increased opening force.
In a preferred embodiment of the invention, a first connection between the retaining strip and the threaded portion is formed along the open edge of the side surface and extends over an arc having a second angle ranging from 10 degrees to 25 degrees. As a result of this wide connection, the retaining strip is firmly held on the threaded portion, whereby unintentional tearing is reliably prevented. It is particularly important when the threaded portion unscrews from the container and high tension is applied to the short retaining strip during this process.
Advantageously, in a cross section along the imaginary section, the first connection between the retaining strip and the threaded portion is 4mm 2 To 6mm 2 . Together with the dimensioning of the second angle, this results in a stable connection of the retaining strip with the threaded part, which connection is subjected to high tension.
In another preferred embodiment of the invention, a second connection between the retaining strip and the tamper-proof ring is formed along the tamper-proof ring and extends over an arc having a third angle ranging from 6 degrees to 10 degrees. Thus, when the threaded portion is unscrewed, the second end of the retaining strip is also held on the tamper-evident ring in a stable manner.
Advantageously, in a cross section along the imaginary section, the second connection between the retaining strip and the threaded portion is 3mm 2 To 5mm 2 . Together with the dimensioning of the third angle, this results in a stable connection of the retaining strip to the tamper-proof ring, which connection is subjected to high tensile forces.
Advantageously, the first end of the retaining strip is connected to the open edge of the threaded portion and the second end is connected to the tamper-proof ring by a first film hinge and a second film hinge, respectively. This facilitates the pivoting of the retaining bar, which is necessary for the open state of the threaded portion. Furthermore, the holding strip reaches a predetermined position by the film hinge in the open state.
It has proven advantageous if the tamper-proof ring has a circumferential stop edge on the side facing the threaded portion. The open edge can be fastened to the stop edge in the open state. This can be achieved by the retaining strip pressing the threaded portion against the stop edge.
In another preferred embodiment, the groove extending in the circumferential direction is provided on the outside of the side surface. In the open state, the groove is pressed against the support ring of the container, whereby the threaded portion can be secured to the container. It is also contemplated that the groove may be secured to the stop edge. The groove may be present only in a specific circumferential portion of the threaded portion or extend completely around the side surface. The groove indicates to the user that it is to be used to secure the threaded portion in the open state. Thus, the grooves improve the intuitive use of the closure.
Advantageously, in the unopened state of the closure, the retaining strip is accommodated in a recess of the tamper-evident ring. Thus, the retaining strip requires only a small additional space and the additional height of the tamper-evident ring is minimal.
It has proven to be advantageous if the at least one first predetermined breaking element and the at least second predetermined breaking element have different tensile strengths or tear resistances, or if an internal thread is formed on the inner side of the retaining strip, which internal thread is capable of interacting with an external thread of the container neck, wherein the third predetermined breaking element has the same tensile strength or tear resistance as the at least one first predetermined breaking element. Thus, the retaining strip may be manipulated during unscrewing to control the retaining strip so that the retaining strip remains in the recess until the retaining strip is pulled upward in a defined manner. Thus, the retaining strip does not have to reach its length during unscrewing, but only when the length is needed for fixing the threaded portion to the container neck.
Because the holding strip has a length of 1.5mm 2 And 2.5mm 2 Cross-section between them, they have an increased torsional stiffness in the longitudinal direction. Thus, the threaded portion in the open position is pressed or rotated in the direction of the container neck.
Due to the increased cross section, the retaining strip protrudes beyond the tamper-evident ring and the side surfaces. Thus, the torsional stiffness of the retaining strip may be increased solely by the retaining strip protruding more or less beyond the tamper-evident ring and the side surfaces. The material used for this is minimal.
Advantageously, the first predetermined breaking element is a first predetermined breaking web and the second predetermined breaking element is a second predetermined breaking web and the third predetermined breaking element is a third predetermined breaking web. The predetermined breaking webs may be defined in such a way that they tear in a defined manner in accordance with the axial forces acting on them.
It has proven to be advantageous to arrange one to three first predetermined breaking webs between the open edge of the threaded portion and the first edge of the retaining strip. It is also advantageous if one to three second predetermined breaking webs are arranged between the tamper-evident ring and the second edge of the retaining strip. The number of first and second predetermined breaking webs determines the degree of firmness with which the retaining strip is secured. The retaining strip is stabilized by a predetermined breaking web during the compression of the closure cap onto the container neck and is not damaged during the compression.
It has proven advantageous if the tear strength of the second predetermined breaking web is greater than the tear strength of the first predetermined breaking web and the third predetermined breaking web. Thus, the retaining strip is retained on the tamper-evident ring when the threaded portion is unscrewed and can be released from the tamper-evident ring when it is desired to press the threaded portion onto the container neck.
Advantageously, the first predetermined breaking web and the second predetermined breaking web are arranged at a uniform distance along the first edge and the second edge, respectively. It is furthermore advantageous if a third predetermined breaking web is arranged at a uniform distance between the threaded portion and the tamper-proof ring.
Another aspect of the invention relates to a container comprising a container body, a container neck with external threads, a support ring formed at the transition from the container body to the container neck, and a closure cap according to the above.
The invention is also characterized in that the free edge or groove of the threaded portion can be latched to the support ring.
Further advantages and features will become apparent from the following description of embodiments of the invention with reference to the schematic drawings. In the drawings, which are not to scale:

Fig. 10: is another isometric view of the closure cap and container, viewed obliquely from above, with the cap latched to the support ring of the container with the channels.
Fig. 1 to 4 show a closure cap, generally indicated by the reference numeral 11. The closure cap 11 is captively held on the container 13 (fig. 8 to 10), in particular on the bottle 13. The closure 11 comprises a cylindrical threaded portion 15, a tamper-evident ring 17 and a retaining strip 19.
The threaded portion 15 includes a top plate 21 and a side surface 23 having an open edge 25. An internal thread 27 is formed on the inner side of the housing 23. The container 13 includes a container body 28 and a container neck 29 adjacent the container body 28. External threads 31 are formed on container neck 29 and interact with internal threads 27. Thus, the threaded portion 15 may be threaded onto the container neck 29 and unscrewed from the container neck 29. The closure cap 11 closes a pouring opening 32 provided in the container neck 29.
The tamper-evident ring 17 is held in a form-fitting manner on the container neck 13. For this purpose, an annular projection (not visible in the figures) is formed on the outside of the container neck 29, and can be engaged from below by a projection 30 formed on the inside of the tamper-evident ring 17. The tamper-evident ring 17 is rotatable relative to the container neck 29.
The retaining strip 19 has a first end 33 and a second end 35. The first end 33 is fixedly connected to the open edge 25. The second end 35 is fixedly connected to the tamper-proof ring 17. Thus, the closure 11 is captively held on the container 13. Furthermore, the retaining strip 19 has a first edge 37 and a second edge 39. The first edge 37 is connected to the open edge 25 by a first plurality of predetermined breaking webs 41 and the second edge 39 is releasably connected to the tamper-resistant ring 17 by a second plurality of predetermined breaking webs 43. Preferably, there are 1 to 3 first predetermined breaking webs 41 and 1 to 3 second predetermined breaking webs 43 and they are arranged uniformly along the retaining strip 19. It is also preferred that the retaining strip 19 has a width between 4mm and 5mm so that the retaining strip is sufficiently stable and that the retaining strip can be manually removed from the threaded portion 15 or the tamper-proof ring 17. A third predetermined breaking web 45 connects the threaded portion 15 to the tamper-resistant ring 17 at a position where the open edge 25 and the tamper-resistant ring 17 are directly adjacent to each other and not separated from each other by the retaining strip 19. The third predetermined breaking web 45 is preferably arranged at a uniform distance between the open edge 25 and the tamper-proof ring 17.
By unscrewing from the container neck 29, the threaded portion 15 can be transferred from the unopened state to the opened state. By screwing it, the threaded portion 15 can be returned from the open state to the unopened state. In the unopened state, the retaining strip 19 is arranged between the threaded portion 15 and the tamper-proof ring 17 and along the circumference of the tamper-proof ring 17. In the unopened state, the retaining strip 19 extends in an arc having a first angle 49 ranging from 30 degrees to 50 degrees and is received in the recess 47 of the tamper-evident ring. The retaining strip 19 is thus integrated into the tamper-proof ring 17 in a space-saving manner.
A first connection 51 between the retaining strip 19 and the threaded portion 15 is formed along the open edge 25 and the first connection 51 extends over an arc having a second angle 53 ranging from 10 degrees to 25 degrees. The first connecting portion 51 is 4mm in cross section along an imaginary section plane that is horizontal to the central axis 55 2 To 6mm 2 。
A second connection 57 between the retaining strip 19 and the tamper-resistant ring 17 is formed along the tamper-resistant ring, and this second connection 57 extends over an arc having a third angle 59 ranging from 6 degrees to 10 degrees. In a cross-section along an imaginary section parallel to the central axis 55, the second connection 57 between the retaining strip 19 and the threaded portion 15 is 3mm 2 To 5mm 2 。
The length of the retaining strip is as short as possible due to the size of the first angle 49. Furthermore, due to its cross section 61 at 1.5mm 2 And 2.5mm 2 The retaining strip 19 has an increased torsional stiffness along its longitudinal axis. Due to this increased cross section, the retaining strip 19 may protrude beyond the tamper-evident ring 17 and the side surface 23. Thus, the retaining strip 19 has a restoring or spring force and will in the open stateThe threaded portion 15 is pressed against the container neck 29.
So that during unscrewing the retaining strip 19, despite its short longitudinal extension, does not tear off the threaded portion 15 or the tamper-evident ring 17, as described above, the first connection portion 51 and the second connection portion 57 are designed with an increased cross section.
The first end 33 of the retaining strip 19 is connected to the open edge 25 of the threaded portion 15 by a first film hinge 63. The second end 35 is connected to the tamper-evident ring 17 by a second film hinge 65. When the threaded portion 15 is shifted to the open state, the retaining strip 19 can be folded out better by the hinges 63, 65.
The circumferential stop edge 67 is placed on the tamper resistant ring 17. In the open state, the threaded portion 15 is pressed against the tamper-evident ring 17 by the retaining strip 19 in such a way that: the open edge 25 can be latched to the stop edge 67.
In another embodiment, a groove 69 extending in the circumferential direction may be provided on the threaded portion 15, which groove may extend around the entire side surface 23. In the open state, a support ring 71, which is normally present on the container neck 29, can latch in the groove 69. The stop edge 67 may also latch into the groove. It is also conceivable that the free edge 25 is latched under the support ring 71. Thus, in the open condition, the threaded portion 15 is fixed to the container 13, so that there is no obstacle when the product is poured or when it is drunk from the bottle 13. The groove 69 serves as a securing aid for the user, since the user intuitively latches the groove 69 to the support ring 71 after the user unscrews the threaded portion 15.
The first predetermined breaking web 41 and the second predetermined breaking web 43 have different tear strengths. That is, the second predetermined breaking web 43 may have a greater tear strength than the first predetermined breaking web 41. The first predetermined breaking web 41 and the third predetermined breaking web 45 may have the same tear strength. Preferably, the first predetermined breaking web 41 and the second predetermined breaking web 43 are arranged or formed on the first edge 37 and the second edge 39, respectively, at a uniform spacing. It is also preferred that the cross-sectional areas of the first predetermined breaking webs 41 are the same size and the cross-sectional areas of the second predetermined breaking webs 43 are the same size.
Because the first and second predetermined breaking webs 41,43 have different tensile and tear strengths, the first and third predetermined breaking webs 41,45 preferably break before the second predetermined breaking web 43 breaks when the threaded portion 15 is unscrewed. After unscrewing the threaded portion 15, the retaining strip 19 thus remains on the threaded portion 15 or on the tamper-proof ring 17. The tamper-evident ring 17 can be displaced in the axial direction by a few millimeters with respect to the annular projection of the container neck. Thus, the retaining strip 19 may be fully retained on the threaded portion 15 or on the tamper-resistant ring 17, since the retaining strip 19 does not have to provide any "height" between the threaded portion 15 and the tamper-resistant ring 17 when the threaded portion 15 is unscrewed. After unscrewing the threaded portion 15, the second predetermined breaking web 43 may be torn off, depending on the length of the retaining strip 19 required to be fixed to the container neck 29.
