CARTON AND LINER FOR SAME Filed Jan. 12. 1952 HU ATTQRNE Y Patented Sept. i8, i934 NITED STATE PATENT eerie CARTON AND LINER FOR SAME Hyman Louis Raxnmer, Stockton, Calif., assignor to Fibreboard Products Inc., San Francisco, Calif., a corporation of Delaware Application January 12, 1932, Serial No. 586,108
My invention relates to packing devices, and one of the objects of my invention is the provision of a carton having a ventilated liner which will resist the action of moisture arising from ma- 5 terials packed therein.
Another object of my invention is the provision of means to reinforce the side walls of a carton, and form a support for the cover flaps.
My invention possesses other objects and features cf advantage, some of which, with the foregoing, will be set forth in the following description of my invention. It is to be understood that I do not limit myself to this disclosure of species of my invention, as I may adopt variant embodiments thereof within the scope of the claims.
Referring to the drawing:
Figure 1 is a plan view of the sheet comprising the liner of my invention, showing the creases and cuts provided to facilitate folding.
Figure 2 is a perspective view of the lcarton embodying my invention, a portion being broken away to show the folded liner or ring in position in the carton.
Figure 3 is a perspective view of a portion of the liner after being creased and cut, but before folding.
Figure 4 is a horizontal sectional view of a corner of the carton with the liner in place to showl the arrangement of the parts.
Broadly, my invention comprises a carton having side and end walls, and flaps on said Walls to provide a top and bottom for the carton. Disposed within the carton and seating snugly against its inner walls is a liner having spaced double walls which reinforce the side walls, and also forms a shoulder on which the closed cover flap may rest.
In greater detail my invention comprises a carton, made preferably of fibreboard or corrugated board, having side walls 2 and end Walls 3 on both of which the bottom flaps 4 and the top flaps 6 are disposed. So far only the conventional folding carton has been described. Such a carton has many uses but it fails to give satisfactory results when used as a container for moisture bearing products such as dried fruits. Prunes, for example, after being dried aresubjected to a steam and dipping treatment immediately before being packed, the hot moist fruit being placed directly in the container which is promptly closed. The usual type of container will not stand up under such use. It begins to wilt within a few moments and in a short time the carton will flatten out and break open. For this reason the packing of prunes and other fruits requiring a similar treatment has been limited to wooden boxes.
The carton of my invention is designed to fulfill the requirements of this trade by providing a liner 7 formed from a single sheet of fibreboard. A wide embossed crease 8 extends the length of the sheet at its center and when folded along this median crease the sheet provides two co-extensive walls 9 and 10 spaced apart by the width 11 between the sides of the crease 8.
Transverse creases 12, also preferably of the wide embossed type which forms a T-shaped bead when folded, extend from one edge of the sheet to the median crease. Extending from the inner end of the creases 12 across the median crease to the opposite edge of the sheet are cuts 13 which are preferably the same width as the embossed creases 12. These creases 12 and aligned cuts 13 are so spaced that when the sheet is folded they form corners which seat snugly within the corners of the carton.
When the carton is to be filled the liner is folded along the median crease, then along the transverse creases `preferably with the cuts onv the outside, and then slipped into the carton. This method of folding is preferred since it insures a Ventilating space between the carton and the liner at each corner. Between the co-extensive walls a dead air space 14 is formed which is closed by the crease 8 along the top edge, by the bottom of the carton along the lower edge, and by the beads formed by the folds i2 at the ends, except at the one corner where the ends of the sheet are abutted. The inner wall 9 of the liner absorbs any moisture from the fruit and the dead air space 14 as Well as the Wall 10, protects the carton so that it is not affected by the moisture or heat.
'I'he width of the liner blank is such that when it is folded and inserted in the carton the upper and lower edges of the lining ring thus formed provide ledges or shoulders extending entirely around the inside of the carton at top and bottom. On these shoulders the cover iiaps rest when closed.
This structure prevents sagging of the cover flaps and relieves much of the strain placed on the thin connection between aps and sides of the carton. The liner also provides a valuable reinforcement against racking under stresses imposed byheavy contents.
A sheet l5 is preferably placed in the bottom of the carton before the lining ring is inserted, and a similar sheet 16 is laid in the top upon the edges of the lining ring before the tcp cover Cil flaps are closed. These sheets provide reinforcement and the extra strength and protection required by such products as dried fruits for the shipment of which my carton is particularly adapted.
1. A carton having side and end walls and flaps on said walls adapted to be folded inwardly to form a top and bottom for the carton, and a liner comprising a sheet having a median crease, transverse creases extending from one edge of the sheet to the median crease and extending to the opposite edge as cuts, said creases comprising an embossed strip forming a T- shaped bead when the sheet is folded, said cuts and creases being spaced to facilitate folding of the sheet into a double Walled ring to flt within said carton.
2. A carton having side and end Walls and flaps on said Walls adapted to be folded inwardly to form a top and bottom for the carton, and a liner comprising a sheet having a median crease, transverse creases extending from one edge of the sheet to the median crease and extending to the opposite edge as cuts, said creases cornprising an embossed strip forming a T-shaped bead when the sheet is folded, said cuts and creases being spaced to facilitate folding of the sheet into a double Walled ring, said bead in each corner forming a shoulder to support the outer Wall of the ring in spaced relation to the inner wall thereof.
3. A liner for a carton comprising a sheet having a longitudinal crease extending the length thereof and forming a T-shaped bead When the sheet is folded, and transverse creases extending from one edge of the sheet to the longitudinal crease and extending to the opposite edge as cuts, opening out on the latter edge, said trans-- Verse creases forming T-shaped beads which provide shoulders on each side of each corner to position the ends of the outer wall of the liner, said sheet when folded comprising a double Walled ring having dead air spaces closed along the top by the longitudinal crease, along the bottom by the bottom of the carton and at the ends by the shoulders formed by a portion of the transverse T-shaped beads.
4. A liner fora carton comprising a sheet i having a length throughout its entire width equal to the inner periphery of the carton and a width substantially equal to twice the depth of the carton, a longitudinal crease extending the length of the sheet, and transverse creases extending from one edge of the sheet to the longitudinal crease and extending to the opposite edge as cuts, opening out on the latter edge, said creases comprising an embossed strip forming a T-shaped bead when the sheet is folded, said sheet'being folded on the longitudinal crease and then on the transverse creases with the`cuts on the outside of the corners to form a ring having spaced walls seating in the carton.
5. A double-Walled liner for a carton comprising ay sheet having a longitudinal crease extending the length thereof, and transverse creases extending from one edge of the sheet to the longitudinal crease and extending to the opposite edge as cuts, said creases comprising an embossed strip which When the sheet is folded displaces a strip of material the Width of the crease from the planes of the adjoining sides to form a T-shaped bead.

A double-walled liner for a carton comprising a sheet having a longitudinal crease extend ing the length thereof, and transverse creases extending from one edge of the sheet to the longitudinal crease and extending to the opposite edge as cuts, said creases comprising an einbossed strip which when the sheet is folded displaces a strip of material the width of the crease from the planes of the adjoining sides to form a T-shaped bead, said beads formed by the transverse creases providing shoulders on which the ends of the outer Walls rest when the liner sheet is folded to space the Walls and close the ends of the chambers between the inner and outer Walls.
'7. A liner for a carton comprising a double Walled rectangular ring, the inner Wall of the liner having folds at the corners to provide beads for spacing the walls apart.
8. A carton having side and end Walls, and a liner for said walls comprising a double walled rectangular ring, the outer Walls of the liner lying snugly against the carton Walls andthe inner walls of the liner having integral folds at the corners to provide beads for engaging the outer Walls to space the Walls apart.
9. A carton liner blank comprising a sheet having a median embossed crease extending the length of the sheet, transversely extending einbossed creases on one side of the median crease and projecting from the surface of the sheet opposite to the median crease, the sheet on the other side of the median crease being severed on lines aligned with the transverse creases, whereby the liner may be folded into a rectangular double-Walled ring.
10.
