I think that is called 'clam shell packaging'. It is useful because you can see the contents, but you can't disturb the what's inside...an inconvenience when you get the product home.

The way I handle this problem is to cut around three sides of the package with culinary shears (or hedge cutters), open it and remove the contents. This is better than smashing or blowing it up, because if you need to return the product you have the original package (to say nothing of having an intact gizmo)...usually a requisite for return.
