- closing element 15 Prior to the first control of closure element 21 from the closing position to the opening position and of closing element 15 from the active position to the inactive position, closing element 15 is fixed to the contact portion.
- the user in order to access the pourable product, needs to control closure element 21 from the closing position to the opening position leading to a movement of main wall 35 from the active position to the inactive position and a rupturing of main wall 35 from the contact portion. This then allows the pourable product to flow from the inner space through flow channel 10 and out of pouring outlet 12.
- main wall 35 covers the designated pour opening.
- number 3' indicates an alternative embodiment of an opening device according to the present invention. As opening device 3' is similar to opening device 3, the following description is limited to the differences between them, and using the same references, where possible, for identical or corresponding parts.
- opening device 3' differs from opening device 3 in that the respective first frame 23 comprises radially extending first ridge elements 30 and radially extending second ridge elements 37. In other words, some of ridge elements 25 of opening device 3' define second ridge elements 37.
- second ridge elements 37 have respective radial extensions such that coupling ring 20 does not fully cover them. In other words, portions of second ridge elements 37 are visible to a user.
- opening device 3' comprises at least two types of ridge elements.
- connection ribs 39 transversal to second ridge elements 37.
- first ridge elements 30 may be arranged about central axis F within a first angular limit and a second angular limit and second ridge elements 37 may be arranged about central axis F within second angular limit and first angular limit.
- opening device 3 and/or opening device 3' and/or of package 1 will be clear from the foregoing description.
- opening device 3 and opening device 3' come along with excellent aesthetics.
- closure group 11 onto collar 9 it is possible to approach coupling ring 20 at least partially closer to first frame 23.
- closure group 11 is arranged on collar 9 and then a force is applied onto closure group 11 such that closure group 11 moves towards base frame 8.
- the maximum stroke of the movement is limited by the uppermost parts of base frame 8 with which coupling ring 20 may interact. Due to the limited extension of first ridge elements 30, coupling ring 20 can get closer to portions of base frame 8, which lie on a lower plane compared to the plane defined by first ridge elements 30, so improving engagement closure group 11 onto collar 9.
- opening device 3 and/or opening device 3' and/or package 1 as described herein without, however, departing from the scope of protection as defined in the accompanying claims.
