Vorratspackung

and for the lively discussion. Dorothy's entry gave me the final solution: ...and to keep handy in the fridge for when you want another one."

...to be directly conveyed in EN. The German has three ideas for these multipacks:
1. They're ideal for sharing with family and friends
2. You can keep them as a 'Vorratspackung'
3. They're great for the times when you fancy another snack.

My gut feeling is to combine ideas 2 & 3. I mean why else would you keep a 'Vorratspackung' if not for eating some later - even if later is just 5 mins after eating the first one! So something along the lines of:
'Ideal for sharing with family and friends or for keeping in stock/in the fridge for when you fancy another snack/one just isn't enough'.

It does deviate slightly from the original meaning, but I don't think badly so. I think it's better that way than trying to fit the three ideas into EN and ending up with a clunky-sounding translation.

Yes, I realised that after posting my answer and added a note to that effect. The idea is still the same, however, that you keep the snack for later consumption.

They can't be stored in the cupboard.
