Instead of having four flaps at the top and bottom, the half slotted carton has only four flaps at the bottom, being covered by a separate lid in the same manner as a set-up paper box. The cover is made of the same kind of double-face corrugated board as the container, and the corners of the cover are stayed. The flaps at the bottom are sealed with sodium silicate, or the joints are sealed with tape. For express shipment, the cover may be tied on. For freight shipment, the cover should be glued on, and completely sealed at the edges with tape.

DOUBLE-WALL CARTON
When an extra-strong carton is needed, the double-wall box is recommended, especially for articles in glass of the half-gallon sizes. This box is of the same style as the regular slotted carton with the exception that the sides and flaps are double thickness, made of one sheet of double-face corrugated stock and one sheet of single-face corrugated board, glued together. In addition to being used for glass articles, the double-wall box is also used for large and heavy goods like mattresses, canned goods, etc.
