6 ,A ,My invention relates to packing devices, and particularly to breboard cartons and means for reinforcing them.
One of the objects of my invention is the pro- 5 vision of a carton having reinforcing columns so that large numbers of lled cartons may be v stacked Without collapsing the lower ones.
Another object of the invention is the provision of means to reinforce the side walls of the carton, and to resist deterioration of the carton by the action of moisture from materials packed therein.
My invention possesses other objects and features ofadvantage, 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: 'v
Figure l is a perspective view showing several cartons embodying my invention stacked together; a portion of the top carton is broken away to show the construction.
Figure 2 is a top elevation of the carton, a. por-g tion being broken away to show the details of construction. l
Figure 3 is a plan view of a fragment of the liner showing the arrangement of the creases forming the cornerr construction.
Broadly, my invention comprises a carton having side and end walls, and flaps on the Walls to provide a top and bottom for the carton.l Dis' posed within the carton; and seating snugly against its inner walls is a liner having wall por- 35 tions to protect and strengthen the carton Walls, and other portions adjacent each corner folded out of the planes of the liner walls to provide a vertical beam and supporting column to reinforce the corners of the carton against transverse and 40 compressive stresses.
In greater detail my invention comprises a' cartom-made preferably of breboard /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. The common carton thus far described has many uses, but it cannot be used as a container for moisture bearing products such as dried fruits. For example, dried prunes are subjected to a steam and dipping treatment immediately before being packed, and the hot moist fruit is packed directly in the ccntainer which is promptly closed. Wooden boxes have been universally used for -handling suchl products, until recently when efforts have been made to utilize'breboard cartons, but with little successi The moisture causes the breboard to vwilt; and in a. short time the carton collapses. Even if it does not actually break down, it will beso weakened that it is impossible to stack one full carton upon another. 1
To overcome' these objectionable features, I provide a liner formed from a sheet or strip of heavy breboard, having a width substantially equal to the depth of the carton. Arranged ne'ar one end of the liner strip is a group of spaced transverse creases-1, 8,*9 and I0, which divide, Vthat portion of the strip in to four panels,A i2, I3, I4 and I5. The second and last panels I3 and I5 are Apreferably of the same width and the panel I2 at the end of the strip is preferably equal to o r greater in width than the panel I3, and constitutes a short wall section of the liner, separated by the three panels I3. I4 and I5 from the longer wall'section Il. The outside creases 'I and I0 are deeply scored to facilitate foldinginwardly, so that when the liner` is folded, the panels ,I3 and I5 are doubled back against theinner side of the adjacent wall'sections I2 and Il.
4The creases 8 and 9 are scored to facilitate folding in the opposite direction from the folding on the creases 1 and I0; and because it is important to avoid cutting or breaking the stock at this point, the creases 8 and 9 are preferably of the embossed wide type which, when folded, form a double or T-shaped bead I8.
When the edges 2| and 22 formed by folding the liner on the creases 'I and IIl respectively are brought into abutting position in the corner of the carton, they form the vertex edge of a right angle triangular prismatic column which ilts snugly into the corner with the perpendicular Isides I3 and I5 of the column lying against the adjacent wall sections'of the liner. '.Ihus, a vertical beam and column is provided which reinforces the carton against both compressive and transverse stresses.
Similar groups of transverse creases are spaced along the strip at intervals to coincide lwith the corners of the carton. In this way the strip is divided into one short section I 2` and four longer Wall sections Il, the longer sections being of substantially the same size as the carton wall which .they overlie, and intol four groups of panels I3, I d and I5A which form the reinforcing column at each corner and separate the main wall sections. When in position in the' carton the columns are rigidly held in position by the liner side walls and by the contents of the carton when If the liner is designed for a small carton a single strip may be creased and folded to form the line'r. In this case the end of the strip having no creases is inserted between the narrow y wall section I2 at the other end of the strip and the panel I3 forming one side of the column. The parts are thus interlocked and held securely in position in the carton. If on the other handthe carton is large it will be found expedient to utilize two like strips tomake up the liner. Each portion comprises two main wall sections, two corner columns, and one short wall section adjacent one end of the strip. The two portions are interlocked in the same manner as described a carton is dropped or subjected to a blow along one of the corner edges the reinforcing column acts as a vertical beam preventing localization of the blow so that it is distributed and absorbed without injury.
I have also found it desirable to line the top and bottom of the carton and for this purpose a sheet of brous material similar to that used for the liner wall sections may be used. The fruit packed in the container of my invention contacts only with the liner walls which absorb the moisture from the fruit and so prevent deterioration of the carton stock.
I claim: K
1. A liner for a carton comprising a strip of Afibrous material having a plurality of transverse creases, and folded to form wall sections and reinforcing columns having a uniform right angled triangular cross section, the perpendicular sides of the column lying snugly in the corners of thecarton. v
2. A liner for a carton comprising `a strip of fibrous material having a plurality of transverse creases, and folded to form wall sections and reinforcing columns having a uniform right angled triangular cross section, the perpendicular sides of the column lying in the corners of the carton and bearing against the adjacent wall sections.
3. A liner for a carton comprising a strip of brous material having a plurality of groups of transverse creases, and folded to form reinforcing columns at each corner, intervening wall sections, and a short wall sectionat one end of the strip between which and the adjoining wall of the column the opposite end of the strip seats to interlock the parts.
4. A liner for a carton comprising a strip of brous material having a plurality of groups of 'transverse creases, and folded to form reinforcing columns at each corner and intervening wall seci tions, coextensive with the walls of the carton so that an end of a wall section 'seats between a column and the carton wall to interlock the parts. 5. A liner for a carton comprising a strip divided into a wall section and reinforcing/panels by parallel transverse creases, and folded about said creases to form the panels into a triangular prismatic column at the corner of the carton, with a substantially 180 degree fold about one crease line to position one panel'flatly against the wall section.
6. A liner for a carton comprising a strip divided into a pair of wall sections and intermediately positioned reinforcing panels by parallel transverse creases, and folded about said creases to form the panels into a triangular prismatic column at the corner of the carton, with substantially 180 degree folds about two ofv the crease lines to position a pair of the panels 40 iiatly against the wall sections.
