3 Claims. (Cl. 225*37) This invention relates to shipping containers for produce such as fruits, vegetables and the like, and more particularly, to a folded shipping container of suitable paper board.

In the shipping of perishable produce such as fruits and vegetables, it is desirable that the containers be L shaped whereby when stacked during storage and shipping there may be ventilation or air circulation around the containers and produce contained therein, and that the containers provide maximum protection of the contents to prevent or reduce possibility of injury due to loads and impacts occurring during shipping and rough handling.

The objects of the present invention are to provide a novel shipping container structure of suitable paper board such as double-faced corrugated board with side walls having vertical portions and downwardly tapered portions for forming ventilation channels and lateral load-bearing surfaces when a plurality of such containers are arranged in side by side or adjoining relation; to provide such a container with facet Wall panels at the corners having angularly arranged upper and lower portions which cooperate with the vertical and tapering portions of the side walls. to retain same in position and add rigidity thereto; to provide such a container with a liner having a shape substantially conforming to and engaging the interior of the side walls with registering openings in the liner and side Walls for ventilation of the contents of the container, and to provide a shipping container of corrugated board that is shaped whereby it is cut and scored and adapted to be shipped fiat and assembled at the point of use in a double wall container having a tapering formation with load-bearing substantially vertical surfaces in each side wall; and to provide such a container that is economical to manufacture, and easily assembled in a shipping container of improved impact and stacking strength and that permits ventilation during storage and shipping to give protection to fruit and produce contained therein.

In accomplishing these and other objects of the invention, we have provided improved details of structure, the preferred forms of which are illustrated in the accompanying drawings, wherein:

Fig. 1 is a top perspective view of a shipping container embodying the features of the present invention.

Fig. 2 is a vertical sectional view through the shipping container taken on the line 22, Fig. 3.

Fig. 3 is a horizontal sectional view through the shipping container on the line 33, Fig. 2.

Fig. 4 is a plan view of the outer wall portion of the shipping container.

Fig. 5 is a top perspective view of a modified form of shipping container.

Fig. 6 is a partial top perspective view of the modified form of shipping container with the top flaps in open position to illustrate the liner therein.

Referring more in detail to the drawings:

1 designates a shipping container generally consisting of, an outer member or box 2 with a bottom closure 3 and a top closure 4, an inner bottom 5 and a wall liner 6, all fabricated from suitable paper board such as double-faced corrugated board that is of' high strength, moistureresistant and relatively stifi when wet. The outer member 2 of the shipping container is preferably formed from a cut and scored blank 7 illustrated in Fig. 4, and including a main body portion 8 of generally segmental shape or form. On one of the side edges of the blank 7 are

extensions

9, 10, 11 and 12 forming bottom closing flaps of the shipping container, and upon the opposite side the blank is provided with

extensions

13, 14, 15 and 16 preferably forming top closing flaps. The

extensions

9, 10, 11 and 12 have their inner edges defined V respectively by

score lines

17, 18, 15 and 2% arranged in end to end angular relation and extending generally longitudinally of the blank. The

extensions

13, 14, 15

and 16 have their inner edges defined respectively by

scorelines

21, 22, 23, and 24, arranged in end to end angular relation whereby the

score lines

21, 22, 23 and 24 are substantially parallel to the

score lines

17, 18, 19 and respectively. The extensions 9 and 10 are separated by a line of cut 25; the extensions 18 and 11 are separated by a line of cut 25; and the extensions 11 and 12 are separated by a line of cut 27. The

extensions

13, 14, 15 and 16 are separated by cuts 28 whereby the

end edges

29 and 30 of each of said extensions are substantially perpendicular to the

respective score lines

21, 22, 23 and 24. a

Extending longitudinally of the blank and arranged in end to end angular relation are a plurality of

straight score lines

31, 32, 33 and 34 arranged intermediate the side edges of the main body portion and parallel with the

score lines

21, 22, 23 and 24 respectively. Diverging

score lines

35 and 36 extend from the intersection of the score'line 17 and end edge 3'7 of the extension 9 to the score line 31 and score line 33 in an end fiap 39 on the body member 3, and then the

score lines

35 and 35 converge to a point of intersection of the score line 21 and end edge 25 of the extension Corresponding diverging score lines 40 and 41 extend from the line of cut 25 to tr e score lines 31 and 32 and then converge to the intersection of the cup 28 that separates the

extensions

13 and 14 and the intersection thereof with the ends of the score lines 21 and 22. Corresponding scores lines 42 and 43 extend from the ends of the line of cut 26 to the score lines 32 and 33, and then converge to the adjacent ends of the

score lines

22 and 23 where they intersect the line of cut 28 between the

extensions

14 and 15. Corresponding

score lines

44 and 45 diverge from the end of the line of cut 27 to the

score lines

33 and 34, and then converge to the adjacent ends of the

score lines

23 and 24 where they intersect the line of cut 23 between the extensions 15 and 16.

The end of the body member opposite from the flap 35 is preferably cut on a line 46 whereby the body portion defined by the

score lines

20, 45, 24, and end edge is a side Wall 47 and substantially the same shape as the body portion or side wall 48 defined by the score lines 123, 41, 22 and 42, and the body portion or side wall 49 defined by the

score lines

17, 36, 21 and 46 corresponds to the body portion or side wall 56 defined by the

score lines

19, 43, 23 and 44.

In the illustrated structure, hand holds 51 and 52 are cut in opposed body portions, for example, between the

score lines

17 and 31 and 19 and 33 respectively. Also, the body portion is provided with a plurality of spaced apertures 53 forming ventilating openings as later described.

In setting up the outer member or box 2 of the shipping container, the blank 7 is bent'on the

score lines

35, 36,

40, 41, 42, 43, 44 and 45 whereby the end portion of tainer and are not transmitted to' the'contents in sufii-i cient force to injure the contents 'of the container,
