Definitions

  • the 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.
  • Closure caps are known from the prior art in the field of plastic closure caps with a guarantee ring, which caps are held captive on the container and close the pouring opening.
  • the holding function is also important insofar as legal provisions are to be expected which will oblige closures of beverage bottles to be captively connected to the beverage bottle even when they are open.
  • a container closure with a threaded part and a guarantee ring is known from the prior art.
  • the open edge of the threaded part is connected to the anti-tamper ring by means of a retaining strap, as a result of which the threaded part is held captive on the anti-tamper ring or the container even after it has been unscrewed from a container.
  • the unscrewed threaded part is in the way when filling is poured out and is also a hindrance to the user when drinking from the bottle.
  • the retaining band can be easily torn off when the bottle is opened, so that the threaded part is no longer held on the guarantee ring
  • CH 715 953 A2 and CH 716 074 A1 disclose closure caps with a first and second retaining strap between guarantee ring and threaded part.
  • the two retaining straps are essential to keep the threaded part in the open position stable and free from wobbling on the beverage bottle.
  • the dimensions and the design of the two holding straps are complex to ensure they function properly.
  • the invention is preferably characterized in that a single retaining strap is provided, the single retaining strap in the unopened state is arranged between the threaded part and the guarantee ring and along the circumference of the guarantee ring and is in an arc of a circle with a first angle in the range from 30 to It stretches 50 degrees, with third predetermined breaking elements being arranged in that section of the threaded part in which the threaded part and guarantee tiering lie directly one above the other.
  • This angular dimensioning enables the formation of a relatively short retaining strap which has a restoring force or spring force and can press the threaded part against the container neck in the open state.
  • the length of the tether therefore enables a stable open position of the threaded portion with a single tether.
  • the third predetermined breaking element not only holds the retaining ring on the threaded part, but also the guarantee ring, which means that the original closure of the closure cap is clearly visible and can be recognized by the increased opening force.
  • the first connection between the retaining strap and the threaded part takes place along the open edge of the lateral surface and this first connection extends over an arc of a circle with a second angle in the range of 10 to 25 degrees. Due to this wide connection, the retaining strap is held firmly on the threaded part, which reliably prevents it from being torn off unintentionally. This is of particular importance when the threaded part is unscrewed from the container and a high tensile force acts on the short retaining strap.
  • the first connection between the retaining strap and the threaded part is expediently 4 mm 2 to 6 mm 2 in cross section along an imaginary cutting plane. Together with the dimensioning of the second bracket, this results in a stable connection of the retaining strap to the threaded part, which withstands high tensile forces.
  • the second connection between the retaining strap and the guarantee ring takes place along the guarantee ring and this second connection extends over a circular arc with a third angle in the range of 6 to 10 degrees.
  • the second connection between the retaining strap and the threaded part is expediently 3 mm 2 to 5 mm 2 in cross section along an imaginary cutting plane. Together with the dimensioning of the third bracket, this results in a stable connection of the retaining strap to the guarantee ring, which withstands high tensile forces.
  • the first end of the retaining strap is expediently connected to the open edge of the threaded part and the second end is connected to the guarantee ring by means of a first or second film hinge.
  • This facilitates pivoting of the retaining strap, which is necessary for the open state of the threaded part.
  • the film hinges hold the retaining strap in a predefined position when it is open.
  • the anti-tamper ring has a peripheral stop edge on the side facing the threaded part.
  • the open edge can be fixed to this stop edge in the open state. This is possible because the retaining strap presses the threaded part against the stop edge.
  • a groove extending in the circumferential direction is provided on the outside of the lateral surface.
  • the groove When opened, the groove is pressed against the support ring of the container, which allows the threaded part to be fixed to the container. It is also conceivable that the groove can be fixed on the stop edge.
  • the groove can be present only in a certain peripheral part of the thread part or completely encircle the lateral surface.
  • the groove indicates to the user that it is to be used to fix the threaded part in the open state. Therefore, the groove improves the intuitive use of the cap.
  • the retaining strap When the closure cap is in the unopened state, the retaining strap is expediently accommodated in a recess in the guarantee ring. As a result, the retaining strap only requires a small amount of additional space and the additional height of the guarantee ring is small.
  • the at least one first predetermined breaking element and the at least second predetermined breaking element have different tensile or tearing strengths or that an internal thread is formed on the inside of the retaining strap, which interacts with the external thread of the container neck can, wherein the third predetermined breaking elements aufwei sen the same tensile or tear strength as the at least one first predetermined breaking element.
  • the retaining strap has a cross section of between 1.5 mm 2 and 2.5 mm 2 , it has increased torsional rigidity in the longitudinal direction. As a result, the threaded part is pressed or rotated in the open position in the direction of the container neck.
  • the first predetermined breaking element is expediently a first predetermined breaking web and the second predetermined breaking element is a second predetermined breaking web and the third predetermined breaking elements are third predetermined breaking webs.
  • the predetermined breaking webs can be defined in such a way that they tear in a defined manner, depending on the axial force acting on them.
  • first predetermined breaking webs are arranged between the open edge of the threaded part and the first edge of the retaining strap. It also proves to be advantageous if one to three second predetermined breaking webs are arranged between the guarantee ring and the second edge of the retaining strap.
  • the number of first and second predetermined breaking points is determined by the holding strap being fixed. When the closure cap is snapped onto the container neck, the retaining strap is stabilized by the predetermined breaking webs and cannot be damaged when it is snapped on.
  • the tearing strength of the second predetermined breaking webs is greater than the tearing strength of the first and third predetermined breaking webs.
  • first and second predetermined breaking webs are arranged at equal intervals along the first and second edge, respectively. is beneficial This also applies if the third predetermined breaking points are arranged at equal intervals between the threaded part and the guarantee ring.
  • Another aspect of the invention relates to a container having a container body, a container neck with an external thread, a support ring formed at the transition from the container body to the container neck, and a closure cap as described above.
