Definitions

  • the invention relates to a closure device according to the preamble of claim 1 for a flexible container, and to a flexible container according to the preamble of claim 19.
  • the known closure devices have a pipe section and a plug molded onto the pipe section on one side, the pipe section and the plug being connected to one another in the circumferential direction of the closure device by a thin-walled connecting section.
  • This thin-walled connecting section is opened when the plug is bent against the pipe section.
  • white fractures of the wall material of the flexible container can occur, as a result of which air can penetrate into the flexible container and, on the other hand, an undesired leakage of the container can result.

  • the closure device consists of a strip-shaped element which is designed with a predetermined breaking line. Breaking off the strip-shaped element along its entire longitudinal extent can be problematic or time-consuming. In this known design, so-called white fractures of the wall material of the flexible container cannot be excluded with certainty.
  • US-A-2 916 886 discloses a flexible container with compartments separated by a sealing strip.
  • an element is movably provided, which can be designed with tips, with which it is possible to separate the sealing strip in order to separate between the corresponding adjacent sections of the To create a fluidic connection.

  • the closure device according to the invention is simple and inexpensive to manufacture and it has the particular advantage that it can be operated easily and without any special effort, ie it can be opened at a given time.
  • the fastening section is formed on its outer surface with at least one circumferential sealing rib.
  • the at least one sealing rib results in reliable melting during the welding process and thus a secure seal.
  • the fastening section surrounding the passage is preferably formed with two circumferential sealing ribs spaced apart from one another in order to significantly improve the reliability of the seal.

If the two elements are pivoted against each other around the film hinge connecting the elements, the at least one membrane is reliably separated along the predetermined breaking line of the membrane with the aid of the associated spur.
