There are a number of ways. In your case your layout reference is incorrect (should be reference="root").

From the controller:

class Chocolate_Box_IndexController extends Mage_Core_Controller_Front_Action
{
    protected function _construct()
    {
        parent::_construct();
        $this->setTemplate('page/1column.phtml');
    }
}

From the layout:

<PRODUCT_TYPE_bundle>
        <reference name="root">
            <action method="setTemplate"><template>page/1column.phtml</template></action>
        </reference>
</PRODUCT_TYPE_bundle>
