FIG. 7 is an enlarged fragmentary vertical sectional view of a detail of the construction of the stacking arrangement incorporated in the top wall of the shipping container, this view being taken in the direction of the arrows along the line 7-7 in FIG. 1.

Referring now to the drawings, the shipping container 10 there illustrated, and embodying the features of the present invention, is especially designed for use in marketing live fowl, such as chickens, ducks, geese, turkeys, etc. More particularly, the shipping container 10 essen tially comprises complementary upper and lower sections 21 and 41, each of substantially pan-like configuration.

The upper container section 21 is of generally rectangular form including a rectangular top wall 22, a downwardly and outwardly directed rectangular marginal wall 23 surrounding the perimeter of the top wall 22, and an outwardly directed rectangular rim 24 surrounding the perimeter of the upper marginal wall 23, the four corners of the upper marginal wall 23 being rounded, as indicated at 25, and the four corners of the rim 24 being rounded, as indicated at 26. The top wall 22 is of sheet-like form having a number of longitudinally extending and laterally spaced-apart ribs or corrugations 27 therein and a number of laterally extending and longitudinally spaced-apart ribs or corrugations 28 therein, the ribs 27 and 28 being disposed in intersecting relation to produce a grid-like or waflie-like pattern upon the top wall 22. The upper marginal wall 23 is of sheet-like form having a number of upstanding rectangular openings 29 formed therein and disposed in spaced-apart relation thereabout and a number of upstanding ribs or corrugations 30 formed therein and disposed in spaced-apart relation thereabout, the openings 29 and the ribs 30 being arranged in alternate positions about the upper marginal wall 23. As best shown in FIGS. 2, 3 and 4, the tops of the ribs 30 provided in the ends of the upper marginal wall 23 may join the outer ends of the longitudinal ribs 27 provided in the top wall 22 and the tops of the ribs 30 provided in the sides of the upper marginal wall 23 may join the outer ends of the lateral ribs 28 provided in the top wall 22. In the arrangement, the ribs 27 and 28 in the top wall 22 project downwardly and the ribs 30 in the upper marginal wall 23 project inwardly; whereby the ribs 27, 28 and 30 have a groove-like appearance from the exterior of the upper container section 21. The upper rim 24 has a downwardly directed channel-shaped cross-section, including inner and outer spaced-apart flanges 31 and 32, as best shown in FIGS. 2 and 3.

The lower container section 41 is fundamentally of the same construction as that of the upper container section 21, as described above; whereby the lower container section 41 is of generally rectangular form including a rectangular bottom wall 42, an upwardly and outwardly directed rectangular marginal wall 43 surrounding the perimeter of the bottom wall 42, and an outwardly directed rectangular rim 44 surrounding the perimeter of the lower marginal wall 43, the four corners of the lower marginal wall 43 being rounded, as indicated at 45, and the four corners of the rim 44 being rounded, as indicated at 46. The bottom wall 42 is of sheet-like form having a number of longitudinally extending and laterally spacedapart ribs or corrugations, not shown, therein and a number of laterally extending and longitudinally spaced-apart ribs or corrugations 48 therein, the two groups of ribs mentioned being disposed in intersecting relation to produce a grid-like or wafiie-like pattern upon the bottom wall 42. The lower marginal wall 43 is of sheet-like form having a number of upstanding substantially rectangular openings 49 formed therein and disposed in spaced-apart relation thereabout and a number of upstanding ribs or corrugations 50 formed therein and disposed in spacedapart relation thereabout, the openings 49 and the ribs 50 being arranged in alternate positions about the upper marginal wall 43. As best shown in FIG. 2, the bottoms of the ribs 50 provided in the ends of the lower marginal wall 43 may join the outer ends of the longitudinal ribs provided in the bottom wall 42 and the bottoms of the ribs 50 provided in the sides of the lower marginal wall 43 may and 48 in the bottom wall 42 project upwardly and the .ribs 50 in the lower marginal wall 43 project inwardly;

whereby the ribs, not shown,'48 and 50 have a groovelike appearance from the exterior of the lower container section 41. The lower rim 44 has an upwardly directed channel-shaped cross-section, including inner and outer spaced-apart flanges 51 and 52, as best shown in FIGS. 2 and 3.

The upper'rirn 24 further comprises a plurality .Of downwardly directed bosses 61 formed in the inner flange 31 and arranged in spaced-apart relation thereabout; and the lower rim 44 further comprises a plurality of upwardly directed bosses 62 formed in theinner flange 51 and arranged in spaced-apart relation thereabout; all as shown in FIGS. 2 and 4. The upper and lower rims 24 and 44 are congruent; whereby the upper container section 21 may be supported upon the lower container section 41 and in assembled relation therewith, when the upper rim 24 is placed over and on top of the lower rim 44. Specifically, when this assembly is produced, the

upper bosses 61 are arranged in superimposed relation with the lower bosses 62; and in order to insure proper positioning of the upper rim 24 upon the lower'rim 44, the top of each lower boss 62 has a counter-bore therein that receives the lower end of the corresponding upper boss 61, as shown in FIG. 4. In order to preserve the assembly of the container sections 21 and 41, a plurality of screws 63 are removably arranged in aligned openings respectively formed through the upper and lower rims 24 and 44 and through the upper and lower bosses 61 and 62. Each screw 63 is retained in place by a cooperating nut 64. Of course, the removal of the screws 63 permits separation of the container sections 21 and 41 and the consequent disassembly of the container 10 for a purpose more fully explained subsequently.

In the container 10, the arrangement of the ribs 27 and 28 in the top wall 22 lends substantial rigidity thereto, and the arrangement of the ribs, not shown, and 48 in the bottom wall 42 lends substantial rigidity thereto. Also the upper marginal wall 23 is rendered rigid by the ribs 30 therein, and the lower marginal wall 43 is rendered rigid by the ribs 50 therein. The cross-section 'of each of the rims 24 and 44 lends substantial rigidity thereto;

and the interfit of the rims 24 and 44 in the assembly renders the container 10 of strong construction and provides a convenient handle to facilitate ready handling of the container 10 and its contents.

7 A doorway 70 is formed in the top wall 22, as best shown in FIGS. 1 and 3; which doorway 70 is suitably framed by surrounding structure 71 that includes a downwardly directed surrounding ledge or lip 72. Also, a pair of grooves 73 are formed in the opposite sides of the structure 71 and a pair of grooves 74 are formed in one end of the structure 71;-which grooves 73 and 74 face upwardly as viewed from the exterior of the top wall 22.

Door structure 80 is carried by the top wall 22 and'essentially comprises a laterally extending mounting strip tions with respect to the doorway 70 due to the provision of the hinge element 83 that is of flexible construction to accommodate ready bending thereof. Also, the door body 82 carries adjacent to the lower side edges thereof a pair of downwardly projecting lips, not shown, that respectively cooperate with the pair of grooves 73 and carries adjacent to one lower end edge thereof a pair of downwardly projecting lips 86 that respectively cooperate with the pair of grooves 74.

Further, the door 80 comprises a latch arrangement 7 for restraining the same in its closed position that includes a flexible tongue 87 formed on the end thereof opposite to the hinge 83; which tongue 87 is adapted to be inserted into 'a cooperating slot formed in the adjacent end of the structure 71. In order to lend desired rigidity to the door body 82, a' plurality of longitudinally extending and laterally spaced-apart ribs or corrugations 88 are provided therein and a plurality of laterally extending and longitudinally spaced-apart ribs or corrugations.

89 are provided therein, the ribs 88 and 89 being disposed in intersecting relation to provide a grid-like structure of wafile-like appearance from the exterior of the door body '82. The ribs 88 and 89 project downwardly from the door body 82 when the same occupies its closed position; whereby the top surface of the top Wall 22 and the top surface of the door body 82 in its closed position are' substantially coplanar, so that the top of the upper container section 21 is substantially fiat. Likewise, the bottom of the lower container section 41 is substantially flat and substantially parallel to the top of the upper container section 21.

In order to insure adequate ventilation of the container 10, a series of holes '91 are formed in the top wall 22,.

virtue of stacking facility incorporated therein. Specifically, the top wall 22 is provided with four upstanding 'pro jections 101 thereon that are arranged adjacent to the four corners thereof, as best shown in FIGS. 1, 2 and 7, and the bottom wall 42 is provided with four upstanding cups 102 thereon, as best shown in'FIGS. 1, 6 and 7. The

projections 101 and the cups 102 are arranged in congruent rectangular patterns, so that when the container 10 is placed upon the top of another such container 10, the four cups 102 in the upper container 10 receive the four projections 101 on the lower'container 10, thereby effectively to interlock the two stacked containers 10 and to prevent accidental lateral displacement of the upper container 10 from the lower container 10.

When the container sections 21 and 41 are disassembled, any suitable number of the container sections 21 and 41 may be nested in each other indiscriminately V merely by inverting the upper container sections 21 and then placing the congruent basket-like container sections.

21 and 41 into each other'.' This arrangement is very advantageous in the storage and the shipment of the container sections 21 and 41 in compact nested position when the same are in knocked-down condition. Of course, the pairs of, container sections 21 and 41 may be readily assembled and disassembled, as required, employing a screw driver for the purpose screws 63.

In'the arrangement, the upper casing section 21.is of one-piece molded construction with all of the elements thereof integral with eachother and formed of synthetic organic plastic material. Similarly, the lower casing section 41 is of one-piece molded. construction with all of a the elements thereof integral witheach other and formed of synthetic organic plastic material. Likewise, the door structure is of one-piece molded construction with all of the elements thereof integral with each other and formed of synthetic organic plastic material. Preferably,

the parts 21, 41 and 80 are molded in corresponding injection steps from linear high-density polyethylene.

At this point, it is noted that linear high-density polyethylene is altogether different from fbranched lowdensity polyethylene, both as to structure and to physical of placing and removing the '7 properties. The linear high-density product may be produced by the Ziegler low-pressure polymerization process and is characterized by a specific gravity in the range 0.941 to 0.965, products having a lower specific gravity in the range 0.926 to 0.940 are referred to as mediumdensity polyethylene; and products having a still lower specific gravity in the range 0.910 to 0.925 are referred to as low-density polyethylene. Linear high-density polyethylene possesses physical properties that are ideally suited as the plastic material of which the shipping container of the present invention is molded. Specifically, linear high-density polyethylene comprises an excellent injection molding material, has a low mold shrinkage characteristic (0.02 to 0.05 in. per in.), has a high tensile strength (3,100 to 5,500 p.s.i.), has a high compressive strength (2,400 p.s.i.), has a high impact strength (1.5 to 12.0 ft./lb. per in. of notch, /2 in. X /2 in. notched bar, Izod test), has substantial hardness (D60 to D70 Shore- Rockwell), has a high resistance to heat (250 F., continuous), has a high heat distortion temperature (140 F. to 180 F., 66 p.s.i.), has a very low water absorption characteristic 0.01% per 24 hours in /8 in. thickness specimens), has a very low burning rate, has an exceedingly high resistance to sunlight, and is very resistant to weak alkalies, strong alkalies, weak acids, strong acids and organic solvents.

After each use, the container 10 may be readily cleaned and washed, either in assembled or disassembled condition, in a ready and simple manner. However, it is ordinarily desirable to disassemble the container sections 21 and 41, since this accommodates more thorough cleaning and sanitizing thereof. Moreover, the container sections are normally returned from the market to the fowl ranch in nested condition, whereby it is very convenient to wash and to sanitize the container sections prior to nesting thereof for the return shipment mentioned.

In view of the foregoing, it is apparent that there has been provided a shipping container for live fowl, or the like, that is of improved construction and arrangement, and essentially comprising upper and lower container sections, as well as a door provided in the top wall of the upper container section, wherein the three fundamental elements thereof named are respectively formed of integrally molded single masses of thermoplastic synthetic resin, such as linear high-density polyethylene.
