  • Container injection mold for producing such a container, and method for changing the dispensing opening during the production of such a container
  • the present invention relates to a container with a container body made of plastic, which is produced by injection molding and forms a receiving space, wherein the container has a container opening and a closure for closing the container opening.
  • the invention further relates to an injection mold for producing such a container and a method for changing the opening cross section of the dispensing opening when producing such a container.
  • closures there is a need for a closure to reliably seal containers of this type. On the one hand, this is intended to prevent a product contained in the container from leaking out. At the same time, the closure can protect a product contained in the container from environmental influences, thus increasing the shelf life of the product. In addition, there is also an interest in designing the closure in such a way that it is easy to see whether the closure has already been opened. Such closures are also known as guarantee closures or tamper-evident closures. These are used in particular in the packaging of food and pharmaceuticals. However, they can also be used effectively in the packaging of other goods.
  • DE 37 27 965 A1 discloses a packaging that comprises a container with a container opening and a screw cap that can close the container opening. Furthermore, a closure body is provided in the screw cap that extends over the container opening and can be removed using a finger tab, so that attempts to open it can be detected.

  • Such a container makes it possible to detect whether the container has already been opened.
  • the tear-off section is separated from the edge section by pulling on the tab, so that the web section forming a predetermined breaking point is inevitably severed.
  • the edge section can remain attached to the container opening after it has been opened for the first time, while the tear-off section is separated from the container. This makes it easy to determine whether the container is still originally sealed or has already been opened.

  • the injection mold element 45 is designed to delimit a surface of the closure body 5 assigned to the side facing away from the tool 40' and at least one surface of the first container component 18.
  • both the casing 42' and the core 4T have the projection 44' on their front surface in order to form the web section 8.

  • Figure 10 shows a perspective view of the tool 40' from Figure 9.
  • the projection 44' surrounded by the casing 42' and core 41' can be seen in particular, which forms a groove in the injection-molded component during the injection molding process, which forms the web section.
  • the projection 44' is designed in such a way that a design of the tear-off section 7 results on the closure body 5 of the container 100', 200', which has a first region 21, a second region 22 and a third region 23.
  • the opening cross-section of the dispensing opening can be changed during the manufacture of a container produced by injection molding. This can be achieved by a different design of the tear-off sections of the containers 200, 200'.
  • the method comprises providing the first tool 40 shown in Figures 7 and 8 and the second tool 40' shown in Figures 9 and 10, wherein, as described, the projection 44, 44' forming the web section 8 is designed differently in the first tool 40 and the second tool 40', such that the size and shape of the dispensing opening 11 is different in a container 200 produced with the first tool 40 and a container 200' produced with the second tool 40'. Since the first and second tools 40, 40' are interchangeable, the first or second tool 40, 40' can be easily inserted into an injection mold to change the opening cross-section of the dispensing opening 11. Containers 100, 100' as described in Figures 1 and 2 can be produced in the same way with appropriately adapted tools.
