Except as otherwise provided in separate descriptions of articles, the following specifications and requirements must be observed for liquids, semi-liquids or articles in liquids, when in plastic bags or semi-rigid containers in fibreboard boxes:
       Containers of three gallon capacity or larger will be considered as 'in bulk' in boxes or drums. When containers have capacity of less than three gallons the bag will be considered an inner container.
       Bags must be of single or multi-ply plastic film having a minimum total wall thickness of not less than three mils (.003 inch) and may be in combination with other materials in laminated form.
    Bags must be closed to effect a liquid tight seal by snap-locking plastic fittings, or by adequately heat sealing, crimping or tying. When wire tie is not plastic coated, ends of wire must be looped. Discharge or dispensing tubes must be securely plugged, crimped or heat sealed. Boxes may be die-cut or perforated to provide an opening for dispensing spigot or valve.
       The filled bags must be in corrugated or solid fibreboard boxes as follows:
          (1) The void between the top of the filled closed bag and the inside of the top of the box must not exceed 1 1/2 inches. The bag must not be adhered to the container at any point.
          (2) Boxes having gross weights not exceeding 20 pounds must be constructed of fibreboard having a bursting strength of not less than 200 pounds or an edge crush test of not less than 32 pounds. Except as to boxes constructed with full overlap inner flaps, boxes must have top and bottom pads made of corrugated fibreboard having a bursting strength of not less than 125 pounds or an edge crush test of not less than 23 pounds.
          Manufacturers' joint of boxes must be taped or glued. Box design may also be a side-slotted tray with a hinge lid. Lid must have full-depth side-panel flanges and a glue-tab panel extending the length of the lid not less than 1 3/4 inches in width. All flaps and panels must be securely glued. Top and bottom pads may be omitted.
          (3) Boxes having gross weights exceeding 20 pounds but not exceeding 40 pounds must be made of fibreboard having a bursting strength of not less than 200 pounds or an edge crush test of not less than 32 pounds. Boxes must have a joined tube or liner made of fibreboard having a bursting strength of not less than 200 pounds or an edge crush test of not less than 32 pounds. The joint of the tube or liner must be taped or glued. Except as to boxes constructed with full overlap inner flaps, boxes must have top and bottom pads made of corrugated fibreboard having a bursting strength of not less than 125 pounds or an edge crush test of not less than 23 pounds. Box design may also be a side-slotted tray with a hinge lid. Lid must have full-depth side-panel flanges and a glue-tab panel extending the length of the lid not less than 1 3/4 inches in width. All flaps and panels must be securely glued. Tube or liner and top and bottom pads may be omitted. Inner edges of minor flaps of tray portion must be crushed 1/4 inch.

OR
          For boxes having a bursting strength of not less than 350 pounds or an edge crush test of not less than 51 pounds, having inner and outer flaps meeting, liner and top and bottom pads may be omitted.
          (4) Boxes having gross weights exceeding 40 pounds but not exceeding 65 pounds must be constructed of fibreboard having a bursting strength of not less than 275 pounds or an edge crush test of not less than 44 pounds. Boxes must have a joined tube or liner made of fibreboard having a bursting strength of not less than 200 pounds or an edge crush test of not less than 32 pounds. The joint of the tube or liner must be taped or glued. Except as to boxes constructed with full overlap inner flaps, boxes must have top and bottom pads made of corrugated fibreboard having a bursting strength of not less than 125 pounds and an edge crush test of not less than 23 pounds. Box design may also be a side-slotted tray with a hinge lid. Lid must have full-depth side-panel flanges and a glue-tab panel extending the length of the lid not less than 1 3/4 inches in width, the tray and lid design must be such that all side panels are two board thicknesses. All flaps and panels must be securely glued. Tube or liner and top and bottom pads may be omitted.
          For boxes of center special full overlap slotted style having gross weights not exceeding 50 pounds and flaps are adhered 50 percent of contact and folded in such a sequence so that a major flap makes up the inside and outside surfaces with minor flaps meeting between forming a total of three thicknesses, tube or liner and top and bottom pads may be omitted.
