Styles of Fibreboard Boxes
(Applicable only in connection with Items 222, 222-1, 222-2, 222-3 and 222-4)
The following are the descriptions of general styles of fibreboard boxes, but not inclusive of all styles:
(a) Conventional Slotted Style Boxes, i.e., Regular Slotted Container (RSC), Half Slotted Container (HSC):
Box is usually made from one piece of fibreboard which is scored and slotted to form a body having flaps for closing each of two opposite faces. Lengthwise flaps either meet or overlap depending on the particular style of the box. Occasionally, slotted style boxes are assembled from more than one piece of fibreboard and have only one closing face.
(b) Telescope Boxes:
1. Full telescope box consists of a body and cover of approximately equal depth sections, cover extending to bottom. (FT)
2. Partial telescope box consists of body and cover of unequal depth sections. The section of lesser depth must extend over the sides of bottom section not less than two-thirds of the depth of the bottom section. (PT)
(c) Boxes with Covers:
1. Single cover boxes consist of a body and a top cover, the cover extending over sides of body less than two-thirds of the depth of body. (SC)
2. Double cover boxes consist of a joined tube (body) and top and bottom covers, covers extending over sides of body. (DC)
3. When the walls of the top or bottom cover have flanges which interlock with flanges of the tube the box is an interlocking cover box. The flanges of the body must be not less than three inches. (IC)
(d) Slide Style Boxes:
Box consists of snugly fitting telescope tubes. The outer tube must be joined.
1. When two tubes are so arranged to provide at least one thickness of fibreboard on all six surfaces, the box is a Double Slide or Single Lined Slide Style. (DS)
2. When three tubes are so arranged as to provide at least two thicknesses of fibreboard on all six surfaces, the box is a Triple Slide or Double Lined Slide Style. The innermost slide need not be water resistant, nor comply with test requirements. (TS)
(e) Folders:
Box consists of one or more cut and scored pieces which provide an unbroken outer bottom surface. The lengthwise outer flaps must meet or overlap.
1. When constructed from a single piece of fibreboard the box is a One-Piece Folder. (1PF)
2. When constructed from two rectangular pieces of fibreboard which provide a double thickness at bottom, the box is a Two-Piece Folder. (2PF)
3. When constructed from three rectangular pieces of fibreboard, the box is a Three-Piece Folder. (3PF)
(f) Five Panel Folder:
Box is formed from a single cut and scored piece so as to provide an unbroken single thickness of fibreboard on three of the six surfaces and usually a double thickness on the remaining three surfaces of the box. (FPF)
(g) Recessed End Boxes:
Boxes must be made from solid fibreboard or singlewall corrugated fibreboard. Recessed ends must be fastened with metal rivets, staples, or stitches, not more than two inches apart. When opening is at top, the top, bottom and sides must be one piece of fibreboard overlapping not less than 1 1/2 inches.
(h) Boxes with Other than Four Sides:
Box must have sides consisting of one piece of fibreboard overlapping not less than 1 1/2 inches fastened with metal staples or stitches not more than three inches apart. Ends of panels of sides must have flanges not less than 1 1/2 inches turned outward or separate pieces of fibreboard covering ends must have as many flanges as panels in sides, which flanges are not less than 1 1/2 inches extending over outside of each panel. In either case, ends of box must consist of one piece of fibreboard with flanges not less than three inches extending over each panel of sides and turned in against sides of box abutting or interlocking with other flanges.
(i) Double Thickness Score Line Boxes:
Box consists of inner tube or slotted container tightly enclosed by regular slotted box, telescope box or box consisting of top and bottom sections which must meet; construction must be such as to provide not less than two thicknesses at all score lines. When inner container is constructed with inner and outer flaps which meet or overlap, outer box may be of one thickness over such flaps; when flaps do not meet or when inner element is a tube, the outer box must be so constructed as to provide not less than three thicknesses over such areas. When outer box is constructed with flanged caps, flanges of such caps must be not less than three inches and must be securely stapled or stitched to inside walls. Manufacturers' joint of inner element and the manufacturers' joints of the outer box must be fastened with metal rivets, staples or stitches not more than one inch apart; OR must lap not less than 1 1/4 inches, and be firmly glued throughout entire area of contact with a glue or adhesive which cannot be dissolved in water after the film application has dried.
The following are the descriptions of general styles of fibreboard boxes, but not inclusive of all styles:
(a) Conventional Slotted Style Boxes, i.e., Regular Slotted Container (RSC), Half Slotted Container (HSC):
Box is usually made from one piece of fibreboard which is scored and slotted to form a body having flaps for closing each of two opposite faces. Lengthwise flaps either meet or overlap depending on the particular style of the box.

(b) Telescope Boxes:
1. Full telescope box consists of a body and cover of approximately equal depth sections, cover extending to bottom. (FT)
2. Partial telescope box consists of body and cover of unequal depth sections. The section of lesser depth must extend over the sides of bottom section not less than two-thirds of the depth of the bottom section. (PT)
(c) Boxes with Covers:
1. Single cover boxes consist of a body and a top cover, the cover extending over sides of body less than two-thirds of the depth of body. (SC)
2. Double cover boxes consist of a joined tube (body) and top and bottom covers, covers extending over sides of body. (DC)
3. When the walls of the top or bottom cover have flanges which interlock with flanges of the tube the box is an interlocking cover box. The flanges of the body must be not less than three inches. (IC)
(d) Slide Style Boxes:
Box consists of snugly fitting telescope tubes. The outer tube must be joined.
1. When two tubes are so arranged to provide at least one thickness of fibreboard on all six surfaces, the box is a Double Slide or Single Lined Slide Style. (DS)
2. When three tubes are so arranged as to provide at least two thicknesses of fibreboard on all six surfaces, the box is a Triple Slide or Double Lined Slide Style. The innermost slide need not be water resistant, nor comply with test requirements. (TS)
(e) Folders:
Box consists of one or more cut and scored pieces which provide an unbroken outer bottom surface. The lengthwise outer flaps must meet or overlap.
1. When constructed from a single piece of fibreboard the box is a One-Piece Folder. (1PF)
2. When constructed from two rectangular pieces of fibreboard which provide a double thickness at bottom, the box is a Two-Piece Folder. (2PF)
3. When constructed from three rectangular pieces of fibreboard, the box is a Three-Piece Folder. (3PF)
(f) Five Panel Folder:
Box is formed from a single cut and scored piece so as to provide an unbroken single thickness of fibreboard on three of the six surfaces and usually a double thickness on the remaining three surfaces of the box. (FPF)
(g) Recessed End Boxes:
Boxes must be made from solid fibreboard or singlewall corrugated fibreboard. Recessed ends must be fastened with metal rivets, staples, or stitches, not more than two inches apart. When opening is at top, the top, bottom and sides must be one piece of fibreboard overlapping not less than 1 1/2 inches.
(h) Boxes with Other than Four Sides:
Box must have sides consisting of one piece of fibreboard overlapping not less than 1 1/2 inches fastened with metal staples or stitches not more than three inches apart. Ends of panels of sides must have flanges not less than 1 1/2 inches turned outward or separate pieces of fibreboard covering ends must have as many flanges as panels in sides, which flanges are not less than 1 1/2 inches extending over outside of each panel. In either case, ends of box must consist of one piece of fibreboard with flanges not less than three inches extending over each panel of sides and turned in against sides of box abutting or interlocking with other flanges.
(i) Double Thickness Score Line Boxes:
Box consists of inner tube or slotted container tightly enclosed by regular slotted box, telescope box or box consisting of top and bottom sections which must meet; construction must be such as to provide not less than two thicknesses at all score lines. When inner container is constructed with inner and outer flaps which meet or overlap, outer box may be of one thickness over such flaps; when flaps do not meet or when inner element is a tube, the outer box must be so constructed as to provide not less than three thicknesses over such areas. When outer box is constructed with flanged caps, flanges of such caps must be not less than three inches and must be securely stapled or stitched to inside walls. Manufacturers' joint of inner element and the manufacturers' joints of the outer box must be fastened with metal rivets, staples or stitches not more than one inch apart; OR must lap not less than 1 1/4 inches, and be firmly glued throughout entire area of contact with a glue or adhesive which cannot be dissolved in water after the film application has dried.
