hinge for ikea corner wall cupboard

IKEA wall corner units are really designed to bridge 2 runs of wall units at 90 deg. The result is that the standard hinge supplied only opens so that it is in line with the hinge side of the cupboard, (presumably to avoid collision with the door in the adjoining unit). ie When the door is shut, the standard hinge is resting at an angle at 135 deg to the cupboard side & only opens to little more than 180 deg.
The cupboard I'm trying to fit will be on its own in the corner & there is also limited access on the non hinge side. So I'd like to find a hinge which will allow the door to swing open from its 135deg shut position to 270deg. That would allow you to see right into the cupboard standing at the side.
I have tried B&Q 180deg hingss but they won't stay shut at the 135deg position.
BTW Ideally I'd like to keep to 'normal' style kitchen unit hinges, like those which came with the units, but which handle the opening angle differently.
Any ideas welcome. TIA

many thanks for the reply. Eventually I went back to IKEA & it turns out I had the wrong hinges. IKEA do a special hinge which opens the corner door fully & properly. Problem was that I hadn't bought the offical angle door & the special hinges only come with the special door. snookered.
