3 Claims. cl. zza-zs This invention relates to multico'mpartment shipping cartons and has for its object to provide a knockdown multicompartment carton that has great rigidity and strength when assembled.
in packaging fragile articles such' as goblets, cups, vases and the like for'shipment, it has been the usual practice to carefully pack the individual articles in a shipping container of rigid construction, the articles being so packed that they are held against relative movement in the container and the container being of a strong and rigid construction so that the articles will not be subjected to 'compi'essiondue to distortion of the container by weightimposed thereon. The alternatives, high cost of shipment, and high percentage of loss due to breakage, have resulted in retail prices so high as to greatly impede the sale of such articles.
The present invention has for an object to provide a knockdown multicompartment carton of paperboard or the like which is of simple and inexpensive construction, which can be shipped and stored in knockdown form, which is easy to assemble, and which has the strength and rigidity necessary for the protection of fragile articles against breakage.
The carton of the present invention has a collapsible body of rectangular form and a combined closure wall and partition structure at one or both ends thereof, the partition structure being formed by integral extension of portions of the closure wall which form an interlocking crisscross system of upright partitions within the body which not only stiffen the end wall structure, but also internally brace the collapsible body portion of the carton.
Reference should be had to the accompanying drawings forming a part of this specification, in which:
Fig. 1 is a plan view of a blank from which a multicompartment carton embodying the invention may be formed;
Fig. 2 is a top plan view of a carton assembled from the blank shown in Fig. 1, portions of the top and bottom walls being broken away to show the interior partition structure;
Fig. 3 is a vertical section through the carton taken on the line indicated at 3-3 in Fig. 2;
Fig. 4 is a vertical section through the carton taken on the line indicated at 4-4 in Fig. 2;
Fig. 5 is a plan view of a blank from which a carton embodying a modification of the invention may be formed;
Fig. 6 is a top plan view of a carton formed from the blank shown in Fig. 5;
Fig. 7 is a vertical section through the carton taken on the line indicated at 77 in Fig. 6; and
Fig. 8 is a vertical section through the carton taken on the line indicated at 88 in Fig. 6.
In Figs. 1 to 4 of the drawings an eight-compartment carton embodying the invention is shown. In the construction shown in Figs. 1 to 4, the eight-compartment carton is a square carton having an open space at the center which is adapted to receive a positioning peg to hold the carton in fixed position on a shelf or in a shipping crate.
As shown in Fig. 1, the collapsible body of the carton is formed by four integrally joined rectangular portions 50 of the blank that are hinged to one another along fold lines 51. The fold lines 51 form three corners of the square carton, and the fourth hinged corner is formed by suitable means such as a tape 52 2,6933% Patented Nov. 2,1954
joining the free ends of the end sections 50 of the blank.
A pair or naps :3 are oined to the bottom edges of an opposed pair of upright walls on by tom lines 54, and each or these flaps has a bottom portion on and a partition portion :0 hinged to the portion so by a torn line 37'. leach ot' the naps :3 has two parallel slots 58 which extend from the IOld lines :54 at right angles thereto across the bottom portion on and partially across the partition portion 56. A second pair of naps 59 are hinged to the bottom edges or the other pair of opposed parallel walls 50 by told lines on, and each or the flaps 59 has a bottom portion 61 and a partition portion 62 hinged to the bottom portion 61 by a fold line 63.
' The width of each flap and the length of the upright wall to which said flap is hinged will hereinafter be considered as being the horizontal dimension measured parallel to the bottom edge of said wall. As herein shown, the width of each flap corresponds to the length of the upright wall to which it is hinged.
In assembling the carton the flaps 53 are first folded inwardly to dispose the bottom portions 55 thereof horizontally between the parallel walls 50 to which the flaps are attached, and the partition portions 56 are placed in upright position parallel to the walls 50 to which the flaps 53 are attached. The flaps 59 are then folded inwardly to bring the bottom portions 61 thereof against the bottom portions 55 and flaps 53, and the partition portions 62 are inserted in the slots 58 of the flaps 53. The partition portions 62 are preferably the same height as the partition portions 56 and the partition portions 62 are provided with notches 64 that register with the partition members 56 and receive the portions of the partition members 56 above the upper ends of the slots. The width of the bottom portions 55 of the flaps is equal to one-third the width of the box so that the partition portions 56 are spaced from one another the same distance that they are spaced from the parallel walls 50.
The width of the bottom portions 61 of the flaps 59 is substantially the same as that of the bottom portions 55 of the flaps 53 so that the partition portions 62 are spaced from one another the same distance that they are spaced from the upright walls 50 disposed parallel thereto.- The bottom portions 55 and 61 leave a square hole in the bottom of the. carton and the central portions of the partitions 56 and 62 enclose the opening at the center of the carton, thus providing eight compartments in the carton and a central open space 65. The eight compartments are provided in a carton which is square in horizontal cross section and which has greater rigidity because of its form than an elongated rectangular carton providing eight compartments by means of intersecting partitions. The top of the container may be provided with conventional cover flaps 66 connected to the top edges of the walls 50 by fold lines 67.
An eight compartment carton can be advantageously formed with an end closure and partition structure at the top as well as at the bottom, in which case combined partition and top wall forming flaps identical with the bottom flaps shown in Fig. 1 may be provided. Where a combined wall and partition structure is provided at opposite ends of the carton the height of the bottom partitions will be less than the height of the container, so that the partition portions of the top structure can register with the partition portions of the bottom structure when the carton is assembled.
Figs. 5 to 8 show an eight compartment container provided with a combined wall and partition structure like that shown in Figs. 1 to 4 except that the partition members are shorter and an identical wall and partition structure is provided at the top of the carton. The flap structure in the modification shown in Figs. 5 to 8 is the same as shown in Figs. 1 to 4 and parts are identified by the same reference numerals with the addition of the letter a. In the form shown in Figs. 5 to 8 the central opening 65a extends entirely through the carton and provides a convenient handgrip for lifting the carton.
It is to be understood that in accordance with the provisions of the patent statutes, variations and modifications of the specific devices herein shown and described may be made Wiflmm departing from the spirit ot' the invention.
