The present invention relates generally to containers. More particularly the invention relates to that type of container which is designed primarily for use in shipping fruit and vegetables, is formed of comparatively stiff material, such as double faced corrugated board, and comprises a rectangular bottom, a pair of opposed, single thickness end walls extending upwards from the end margins of the bottom and a pair of opposed, double thickness side walls extending up-- wards from the side margins of the bottom, consisting of spaced apart outer and inner parts and having the upper margins of their parts joined together by inverted U-shaped folds.

One object of the invention is to provide a shipping container of this type which is an im provement upon, and has certain inherent advantages over, previously designed containers of the same general character and is so constructed or designed that it has a high degree of strength and may be manufactured at a low cost and assembled with facility.

Another object of the invention is to provide a shipping container of the type under consideration in which the inverted U-shaped folds whereby the upper margins of the outer and inner parts of the double thickness side walls are connected together have longitudinally extending slots intermediate their end portions, the single thickness end walls have hinged to their upper margins complemental cover-forming members, and such members have on the outer portions of their side margins downwardly extending flaps which are adapted to extend through the slots and fit between the outer and inner parts of the side walls and serve not only to reenforce the side walls but also to hold the cover-forming members either in a fiat position when the container is provided with a so-called fiat pack or in an upwardly inclined position when the container is provided with a so-called bulged pack.

Another object of the invention is to provide a shipping container of the last mentioned type and character in which the single thickness end walls are hinged to the end margins of the bottom in order that when the flaps on the coverforming members are removed from inserted relation with the outer and inner parts of the side .walls they may be swung outwards into a position wherein they extend at approximately a 45 angle with respect to the horizontal and convert the container into a display package for counter use.

Another object of the invention is to provide a shipping container of the last mentioned character in which the hinged end walls have on the side margins thereof inwardly extending flaps which fit between the end portions of the outer and inner parts of the side walls and are so shaped that in connection with outward swing- 1 Claim. (Cl. 229-33) ing of 1 the end walls their free ends swing into abutment with the edges of the inverted U- shaped folds that define the ends of the aforementioned slots, and coact with such edges to limit outward swinging of the end walls to approximately a 45 angle with respect to the horizontal.

Ajfurther object of the invention is to provide a shipping container of the type and character under consideration in which the inwardly extending flaps on the side margins of the end walls have the upper free corners thereof cut away in order to accommodate the depending flaps on the outer portions of the side margins of the cover-forming members when the last mentioned flaps are inserted downwards through the slots in connection with closing of the cover-forming members.

A still further object of the invention is to provide a shipping container which is generally of new and improved construction, effectively and efiiciently fulfills its intended purpose and is both durable and light in weight.

Other objects of the invention and the various advantages and characteristics of the present container will be apparent from a consideration of the following detailed description.

The invention consists in the several novel'features which are hereinafter set forth and are more particularly defined by the claimed; the conclusion hereof.

V

The container which is illustrated in the drawings constitutes the preferred embodiment or form of the invention. It is primarily designed as a medium orinstrumentality for shipping fruit and vegetables and as its principal components comprises a bottom wall I 0, a pair of opposed double thickness side walls I I, a pair of opposed single thickness end walls I2, and a pair of complemental cover forming members I3. These components are preferably formed of double faced corrugated board in order that the container as a whole possesses the desired rigidity and strength. Generally speaking, the container is rectangular and its height is materiallyless than its width. It is formed of a one-piece blank in order that it may be manufactured and produced at a low cost and also assembled or handled with facility.

The bottom IQ of the container is fiat. It is rectangular in shape and, except for the slots specifically referred to hereafter, is imperforate.

The opposed double thickness side walls II are the same in height, extend upwards from the side margins of the bottom I and are disposed at a 90 angle with respect to the bottom. They are of uniform height from end to end and consist of outer parts I4 and inner parts I5. The lower margins of the outer parts I4 are formed integrally with the side margins of the container bottom and are connected to the last mentioned margins by right angle folds or bends. The inner parts I5 of the side walls are substantially the same in shape as the outer parts and have the upper margins thereof joined to the upper margins of the outer parts by inverted Ill-shaped folds I5. Thelatter serve to space the inner parts small distances inwards'from the outer parts and have intermediate their end portionslongitudinally extending slots IT. The lower margins of the side wall inner parts I5 are provided with integral downwardly extending tongues I8 and these, as best shown in Figure 6' of the drawings,

fit within slots I5 in the side margins of the container bottom I5. Preferably the tongues I8 are located directly inwards of. the ends of the inner parts I5 of the container side walls. In assembling the container the outer parts I4 are first bent upwards with respect to the bottom. Thereafter the inner parts I5 are swung downwards throughout arcs of approximately 180. In connection with folding of the inner parts I5 into place the tongues I8 on the lower margins of the inner parts snap into interfitting or interlocked relation with the slots I9 in the side margins of the container bottom. As soon as the tongues snap into place they serve to hold the inner side wall parts I5 in their operative position wherein they are. spaced inwards smalldistances from the outer parts I4.

The opposed single thickness end walls I2 have the lower margins thereof connected to the end margins of the containerbottom by hinge variety .fol'ds 20 in order tha tthey are capable of beingswung outwards from a normal vertical position into a position wherein they are inclined upwards at approximately a angle with respect to the horizontal and serve to convert the container into a display package for counter use, as shown in Figure 6. The side margins of the end walls I2 are provided with integral inwardly extending flaps 2I which fit between the end portions of the outer and inner parts of the side walls. Such flaps are of greater length than the outer and inner parts of the side walls are high and have the upper free corners thereof cut away in order to form or provide cutouts 22. They have a threefold purpose in that they serve to reenforce the double thickness side walls II, serve frictionally to hold the end walls I2 in place when the latter are in their normal position wherein they extend upwards as shown in Figure 3, and also serve tolimit outwardswinging movement of the end walls when the latter are swung outwards in order to convert the container into a display package. As shown in Figure 6, when the end walls I2 are swung outwards so that they extend at approximately a 45 angle with respect to the horizontal the lower free corners of the flaps ZI are brought into abutment with the edges of the inverted J-shaped folds I6 that define the ends of the longitudinally extending slots I7 and coact with such edges to limit further outward swinging of the end walls. The upper portions of the flaps 2i have inclined edges 23 adjacent the cutouts 22 in order to swing clear of the inverted U-shaped folds I5 when the end walls I2 are swung outwards. In assembling the container the end walls I2 are swung upwards before the inner parts I5 of the side walls are swung into place. After upward swinging ofthe end walls with respect to the container bottom I5 the flaps 2I are folded into lapped relation with the inner surfaces of the end portions of the side wall outer parts I4. Thereafter the side wall inner parts are swung downwards and locked in place by insertion or the tongues I8 into the slots I9.

The eompnrnentai cover forming members It are connected by hinge type folds 24 to the upper margins of the coriain'er end walls I2 in order that they be swung inwards into closed position and upwards into open position. The combined size or area of the cover forming members I3 is such that when the members are folded inwards and downwards into their fully closed position as shown in Figure 3, they form a substantially complete cover for the compartment that is formed by'the bottom; side and end walls of the container. The outer portions'of the side margins of the cover forming members I3 are provided with integral downwardly extending' flaps 25. When the end walls I2 of the containerf are in their vertical position and the cover forming members I3 are swung inwards and downwards these flaps 25 are adapted to'extend through the longitudinally extending slots l'l in the inverted U-shaped folds I6 and fit between the inner upper portions of the outer and inner parts It and I5 of the end walls II as shown in Figures 1', 2, 3 and 5. The flaps 25 have a twofold purpose in that they serve not only to reenforce the side walls I, but also to hold the cover forming members I3 either in a flat position when the container is provided with a so-called flat pack (see Figures 1 and 3), or in an upwardly and inwardly inclined position when the container is provided with a bulged pack (see Figure 2). Preferably the flaps" 25 are downwardly tapered in order to facilitate insertion into the slots l1. When the flaps are in place within the upper central portions of the outer and inner parts of the container side walls they fit in the cutouts 22 in the flaps 2|, as shown in Figure 3.

The side and end walls of the container are provided with holes 26 for purposes of ventilating the container interior. If desired, the upper central portions of the outer parts I4 of the side walls may be provided with trapezoidal cutouts 21 to accommodate the platen of a stapling device in the event that it is desired to staple the flaps 25 to the side wall outer parts in accordance with the method that is disclosed in, and forms the subject matter of my pending United States patent application Serial No. 90,577, filed April 30, 1949 and entitled Art of Packaging.

When it is desired to use the container in connection with a so-called fiat pack. i. e., a pack that is disposed whollywithin the container coinpartment that is defined by the bottom, side and end walls, the cover forming members I3, after packing of the container, are swung inwards and downwards into a flat or coplanar position as shown in Figures 1 and 3. In connection with swinging of the cover forming members into place the flaps 25 are inserted into the slots ll so that in connection with completion of swinging of the cover forming members into place they swing into a position between the upper central portions of the outer and inner parts of the side walls ll. As heretofore pointed out, the flaps 25, when in place, not only reenforce the side walls, but also maintain the cover forming members in place. When the container is packed with a so-called bulged pack, i. e., a pack which projects to some extent above the container side walls, the cover forming members l3 are swun but partially inwards and downwards, as shown in Figure 2. It is contemplated, however, that in connection with partial closing of the cover forming members portions or the flaps 25 will extend through the slots 11 and between the central upper portions of the outer and inner parts of the side walls in order that the flaps 25 will frictionally but releasably hold the cover forming sections in place. After the container has been used for shipping purposes and it is desired to convert it into a display package for use on a counter the flaps 25 are released from the container side walls and the complemental cover forming members l3 areswung outwards. Thereafter the end walls I2 are swung outwards until the inner ends of the flaps 2| arrest further outward movement as the result of abutment against the edges of the inverted U-shaped folds l6 that define the ends of the slots ll.

The herein described container, due to its particular design and construction, may be manufactured at a low cost and assembled with facility. It effectively and efficiently fulfills its in tended purpose and is characterized by a high degree of strength. Due to the flap arrangement on the complemental cover forming members such members may be retained either in afully closed position when the container is provided with a flat pack or in a partially opened position when the container is provided with a outwards in connection with conversion of the container into a display package.

The invention is not to be understood as restricted to the details set forth since these may be modified within the scope of the appended claim without departing from the spirit an scope of the invention.

Having thus described the invention what I claim as new and desire to secure by Letters Patent is:

As a new article of manufacture, a shipping container formed of comparatively stiff material and comprising a rectangular bottom, a pair of opposed double thickness side walls of materially greater length than height, connected to, and extending upwards from, the side margins of the bottom, consisting of spaced apart substantially coextensive outer and inner parts, and having the upper margins of their outer and inner parts joined together by inverted U-shaped folds with longitudinal slots intermediate their end portions, a pair of opposed end walls of the same height as the side walls, having the lower margins thereof hinged to the end margins of the bottom so as to permit them to swing back and forth between a position wherein they extend upwards at right angles to the bottom and a position wherein they extend outwards at an obtuse angle to the bottom, flaps of greater length than the side and end walls are high, connected to, and extending inwards from, the side margins of the end walls, fitting between the end portions of the outer and inner parts of the side walls, having the upper free corners thereof cut away so as to form cutouts and cause the subjacent end portions to be of reduced height, and adapted when the end walls are swung outwards into the second mentioned position to have the upper margins of their subjacent end portions abut against the edges of the inverted U-shaped folds that define the ends of the slots and coact with said edges to limit outward swinging of said end walls to a predetermined obtuse angle, and a pair of complemental cover forming members hinged to the upper margins of the end walls and embodying on the outer portions only of the side margins thereof depending fiapswhich are of materially less length than the members, are adapted when the end Walls extend upwards at right angles to the body to extend downwards through REFERENCES CITED The following references are of record in the file of this patent:
