Meta Tag updated but old one on Google search ?

Hello, I am sorry for posting a new topic for this but I did not find anybody with similar question...

I have added as I gues too short meta tag description on my shop,
so when you seach me on google the description there seems to be ugly...

Coshino Strickwaren Shop. ... 0 Produkt(e) - 0,00€. www.coshino.de · Start Produkte Produktinfo Mein KontoWarenkorbKasseKontakt. 10ste 20te 30te ...

(the last one are my Slideshow banners -> OMG !!)

I've changed with new, longer meta tag description so the 0 Products, 0,00€ should disapear but nothing happend.
I gues google bot has to come again and see the changes but it did not changed for a week so,
what's on chaning meta tag discription and updating google for the changes ?

Ok sloved, it looks like it just took longer time to change...
If anybode has the same problem, just be patient a week or more
