Generic Product Carton design

We have two cartons used for specific products we sell. We now require a generic box which could be used for sending out a range of different products, but we want to maintain a consistent brand image.
Attached are pdf's of the boxes we presently use, the new one needs to have company logo, address / contact details, content "pane" where a sticker can be placed to identify the contents.
Box size 140mm x 100mm x 40mm
