, MILTON W. HERZOG finm ATTORNEY United States Patent CARTON LINER Milton W. Herzog, Valley Stream, N. Y., assignor to Delamere Company, Inc., a corporation of Delaware Application November 30, 1955, Serial No. 549,998

3 Claims. (Cl. 229-14) Liners of that type that have heretofore been proposed have required an excessive amount of time and labor to fold them into proper condition for insertion in the carton. While such liners serve to protect the packed articles from being broken or damaged in transit, especially in the case of light-weight fragile articles, nevertheless their use has hitherto been limited because of the abovenoted objection, as well as for other reasons.

With the defects of the prior art liners in mind, it is an object of my invention to provide an improved foldable liner that upon being folded for insertion into a carton has self-forming corner pieces that act as struts to space the side walls of the liner inwardly from the corresponding side walls of the carton and hold them in such spaced relation.

Another object of my invention is to provide a foldable liner that can easily be formed in condition for insertion into a carton with a minimum expenditure of time and labor.

Still another object is. to provide a foldable liner of simple and inexpensive construction, the body of the liner being formed entirely of a one-piece foldable blank.

A further object is to provide a liner comprising a one-piece body member that can be readily folded manually into shape by merely bending up the side portions thereof, whereupon the corner portions will be selfformed, or that can be automatically folded by placing the blank in centralized position on the top of the open carton, and then applying downward pressure on that portion 'of the blank that will constiute the bottom of the inserted liner.

Ather objects and advantages of the invention will appear from the following description thereof, reference being had to the accompanying drawings, in which:

Fig. 1 is a perspective view of a conventional form of carton in which my improved liner hasbeen inserted;

Fig. 2 is a longitudinal cross-sectional view taken on the line 2-2 of Fig. 1; I

Fig. 3 is a transverse sectional view taken on the line 33 of Fig. 1; I

Fig. 4 is a top sectional view taken on the line 4-4 of Fig. 1;

Fig. 5 is an exploded view in perspective of the folded liner blank and its cover member;

Fig. 6 is a plan view of the liner blank in its normal flat state before being folded, the dash lines on the face of the blank indicating the scoring along which the blank will fold; and v Fig. 7 is a perspective view of the blank in partly folded condition.

The carton or outer container 10 is of the conventional type used in shipping light-weight articles. It is generally rectangular in shape and made of corrugated ice paperboard or the like. No invention is claimed in the carton per se.

The improved foldable liner to which this invention particularly relates comprises a body member 11, which member is made of a cut and scored blank 12 consisting of .a single flat sheet of paperboard, such as corrugated paperboard, or other suitable material. A preferred form of blank is shown in Fig. 6 in which the cut edges are delineated in solid lines, while the scored portions, along which the blank is to be folded to form the liner body member 11, are indicated by dash or broken lines. The liner may be provided with a cover member 13, preferably made of the same material as the blank 12.

The blank 12 has a substantially rectangular central portion 14 that forms the bottom of the liner body member 11 when the blank is folded. Along the four sides of the central portion 14 are mutually opposed parallel side portions 1515 and 16-16, which side portions are defined by scores 17 and 18, and cuts 19, 20, and 21, respectively. The cuts 19 and 21 extend inwardly to form integral extensions 22 and 23 of the side walls that, when the blank is folded, serve as legs for supporting the liner body member in the carton with its bottom 14 spaced from and above the bottom of the carton. The cuts 20 extend outwardly from the central portion 14 of the blank to form integral projections 24 of said portion, which projections 24 serve as additional means for spacing the walls of the liner inward from the walls of the carton. If desired, these projections may be eliminated.

The side and end wall portions 15 and 16 respectively are connected by corner portions 25 each of which has a reentering right-angle, and a score 26 that runs from a corner of the central portion 14 to the vertex of the angle. When the blank is folded, the two parts of each angle portion are brought together in facial contact with each other to form the corner struts 27, as best seen in Figs. 4 and 5, which struts hold the liner body member spaced inward from the corners and sides of the carton. On folding the blank, the scores 26 form the inclined bottom edges 28 of the struts.

The outer edges of the side portions of the blank 12 may have cut-outs or recesses 29 and 30 formed therein. In the particular form of blank shown, the cut-outs 29 of the side portion 15 are spaced apart to leave intervening portions or tongues 31 which tongues are adapted for insertion in the slots or openings 32 in the liner cover member 13, as seen in Fig. 4. The ends 33 of the cover member may be shaped, as shown, to seat in the recesses 30 of the body member. Upstanding flanges 34 may be formed along the sides of the cover. It will be understood that instead of having the ends of the cover seat in recesses, the body and cover may be formed with tongues 31 and slots 32 at all four sides instead of at two of the sides, only.

To form the blank into condition for insertion into the carton, it is merely necessary to bend the side portions A-A and B-B upwardly, as indicated in Fig. 7. On so bending the side portions, the four corner portions will be self-bent upwardly and outwardly in position, for insertion into the carton without the necessity for any further or additional operation. As an alternative, the blank may be automatically formed into shape by laying it in centralized position over the open top of the carton and pressing it into the carton by application of downward pressure against its bottom C as indicated by the vertical arrow in Fig. 7. In either case the corner struts will be self-forming.

It is to be understood that while I prefer to employ a blank having a substantially rectangular central portion, that portion may be of other suitable shapes, de-

liner for removable insertion into the carton, which liner comprises a flat horizontal bottom portion, vertical side and end portions, said side and end portions having integral projections that extend downwardly from their lower edges to provide legs for supporting the bottom portion of the liner upwardly from the bottom of the carton, and outwardly extending integral corner portions at the four corners of the liner between the side and end wall portions thereof to space said walls inwardly from the corresponding walls of the carton.

2. In combination with a shipping carton, a one-piece liner for removable insertion into the carton, which liner comprises a flat horizontal bottom portion, vertical side and end portions, said side and end portions having integral projections that extend downwardly from their lower edges to provide legs for supporting the bottom portion of the liner upwardly from the bottom of the carton, and outwardly extending integral corner portions at the four corners of the liner between the side and end wall portions thereof to space said walls inwardly from the corresponding walls ofthe carton, the upper ends of said corner portions extending upwardly above the upper edges of the side and end walls to space the liner downwardly from the top of the carton.

3. In combination with a shipping carton, a onepiece liner for removable insertion into the carton, which liner comprises a flat horizontal bottom portion, vertical side and end portions, said side and end portions having integral projections that extend downwardly from their lower edges to provide legs for supporting the bottom portion of the liner upwardly from the bottom of the carton, outwardly extending integral corner portions at the four corners of the liner between the side and end wall portions thereof to space said walls inwardly from the corresponding walls of the carton, the upper ends of said corner portions extending upwardly above the upper edges of the side and end walls to space the liner downwardly from the top of the carton, and a detachable cover member supported on the upper edge of the side and end walls with the corner pieces extending upwardly above the plane of the cover member.
