Opening Tetrapak dreamcap on shabbos

Some cartons have a lid called the tetrapak dreamcap. This is an ingenious design where as you unscrew the cap, you drive a serrated plastic blade into a foil seal underneath, cutting out a perfect little hole and folding the flap back. I’ll include a link to a short video that demonstrates the mechanism: DreamCap 26 - YouTube

Is it permitted to open such a container on shabbos?
