Patented Nov. 22, 1949 COLLAPSIBLE TRAY OR CARTON Kenneth T. Buttery, Kalamazoo, Mich., asslgnor to Sutherland Paper Company, Kalamazoo, Mich a corporation of Michigan Application December 29, 1945, Serial No. 638,165
14 Claims. (Cl. 229-32) This invention relates to improvements in collapsible trays or cartons.
The main objects of this invention are:
First, to provide a collapsible tray or carton formed of an integral blank which'may be easily and quickly erected and one in which the walls when erected are effectively interlocked and supported.
Second, to provide a tray or box formed of an integral blank which may be shipped or transported in the knockdown and quickly set up by a relatively inexperienced person and when set up is quite strong and rigid even when formed of relatively light stock.
Objects relating to details and economies of the invention will appear from the description to follow. The invention is defined and pointed out in the claims.
Preferred embodiments of the invention are illustrated in the accompanying drawings, in which:
Fig. 1 is a perspective view of a tray or carton embodying my invention erected.
Fig. 2 is a plan view of the carton collapsed or in the flat.
Fig. 3 is an enlarged fragmentary view in vertical longitudinal section.
Fig. 4 is a fragmentary perspective view illustrating certain of the steps in erecting the structure and the relation of parts of the structure.
Fig. 5 is a fragmentary perspective view further illustrating the preferred steps in setting up the carton.
Fig. 6 is a perspective view of a somewhat modified form or embodiment of the invention.
Fig. 7 is a plan view of the embodiment of the invention shown in Fig. 6 fully collapsed or in the fiat.
Fig. 8 is an enlarged fragmentary view further illustrating structural features of the invention of Figs. 6 and 7.
My improved collapsible tray or box or carton is formed of an integral blank and comprises a bottom I, side walls 2, 2, and end walls 3, 3, the side walls being hingedly connected to the bottom along the score lines 4, 4 while the end walls are hingedly connected to the bottom along the score lines 5, 5. The end walls 3, 3 have corner flaps 6 on their end edges hingedly connected thereto at I.
In the embodiment shown in Figs. 1 to 5 inclusive, the end walls and their corner flaps are substantially greater width than the side walls, thus providing when the box is erected a structure having the efiect of recessed side walls for exposing the contents, the higher end walls and corner flaps supporting the cover or wrapping which is commonly of transparent material so that the goods are exposed and may be inspected not only through the top of the box or wrapper but through what amounts to recessed sides.
It will be noted that the bottom edges 8 of the corner flaps are in alignment with the scores or hinged connections 5 for the end walls to the bottom and that the end edges 9 of the sides are spaced from the bottom edges 8-that is, when the blank is considered in the fiat.
The side walls have slits l0 opening at their end edges and extending diagonally outward from adjacent their bottom edges or adjacent the hinge connection 4 to the bottom. These slits, as illustrated, have outer end portions ll disposed at an angle to their inner or main portions, this resulting in the forming of keeper-like portions l2 above the slits. The end portions In of the end walls above the slits constitute tongue-like members which are readily deflectable inwardly to facilitate insertion of the corner flaps through the slits and the engagement of the corner flaps with the side walls and generally to facilitate the erection of the structure.
The corner flaps have slots l4 inclined downwardly from their outer edges providing upwardly'projecting tongues i5. The tongue portions of the corner flaps are somewhat narrower than the outer portions of the corner flaps l6 and the corner flaps are desirably beveled at I l to further facilitate erection of the carton.
To erect the carton, the sides are swung upwardly and an end grasped by grasping the corner flaps and swinging the same inwardly against the deflectable portions l3 of the side walls which permits the bottom edges of the corner flapsto be inserted through the slits ID as shown in Figs. 4 and 5, bringing the tongues l5 into engagement with the portions of the side walls above the slits and with the keeper-like angled portions it! when the end wall is completely erected. It will be noted that the bottom portions of the corner flaps lie within the side walls and that they are in supported engagement with the bottom, thus maintaining the end walls in their erected position substantially at right angles to the bottom. The upper portions of the corner flaps are on the outer side of the deflectable portions of the side walls so that although these end portions of the side walls are weakened somewhat by the slits, this is counteracted or offset by the supporting engagement of the corner flaps with the side walls.
aisavos The structure may be quickly erected and at the same time is very effectively supported in erected position.- The extending end walls and corner flaps provide an effective support fora cover or wrapping and permit the use of narrower side walls which also constitutes a saving in material as well as aiding in attractive packaging.
In the embodiment of my invention shown in Figs. 6, 7 and 8 the container is somewhat flared and comprises a bottom It, side walls I! and end walls 20, these walls being tapered inwardly. The side and end walls are provided with hinge connections to the bottom conventionally illustrated The side and end walls have top flaps 22 and 23 relatively hingedly connected thereto by hinging, indicated conventionally at 24. These form cover or wrapper supporting flanges as is shown in Fig. 6. The corner flaps 25 are hingedly connected to the ends of the end walls at 20 and they are provided with hooked tongues 21 on their side edges. The side walls have slits 28 extending from their end edges, the inner ends of the slits being somewhat hook-shaped as shown at 29 to provide keeper-like portions It with which the tongues engage. The portions SI of the end walls above the slits are deflectable to facilitate engagement of the tongues when the structure is erected substantially as has been described.
In this structure, the bottom portions of the corner flaps lie within the side walls and their upper portions are on the outer sides of the side walls substantially as I have pointed out. The parts in the erected structure are effectively retained throughout and in effective supporting relation to each other. This enables the use of relatively light stock. The facility with which the structure may be erected is, however, a major advantage or accomplishment of my invention.
I have illustrated and described my invention in two practical embodiments thereof. I have not attempted to illustrate or describe other modifications or adaptations as it is believed that this disclosure will enable those slnlled in the art to embody or adapt my invention as may be desired.
Having thus described by invention, what I claim as new and desire to secure by Letters atent, is:
