Jan. 10, 1956 F. R. MUELLER SHIPPING CONTAINER Filed Jan. 2, 1953 IN VEN TOR. HA 1P0 NUEZLE/P III SHIPPING CONTAINER Fred Richard Mnelier, Euclid, Ohio, assignor to Cozier Container Corporation, Cleveland, Ohio, a corporation of Ohio Application January 2, 1953, Serial No. 329,231 2 Claims. (Cl. 229-14) This invention relates broadly to cartons and more specifically to improvements in corrugated board packing cases for relatively large heavy articles.
One of the objects of the invention is to provide a reinforcing frame in the base of the carton to facilitate the anchorage of the merchandise within the case and restrain movement thereof While the goods are in transit.
Another object of the invention is to provide a removable liner for the carton which not only serves to support the goods against lateral movement within the case but also serves to restrain movement of the inner frame members and reinforce the side walls of the carton.
Another object of the invention is to provide a secondary top closure plate embodying depending flanges adapted for engagement between the top of the liner and the upper ends of the side walls of the carton to prevent deformation of the case.
Another object of the invention is to provide an end closure structure in which the end portions of the side panels of the carton are folded back upon themselves and enveloped by the refolded flanged edges of the cap and base in order to effect an interlocked connection between the side walls and end plates.
Another object of the invention is to bind the folded portions of the cap and base with a metallic band or wire to assure the retention of the parts in their assembled relation.
Further objects of the invention reside in the provision of a carton which is sturdy of structure, economic of manufacture, durable in use, and of adequate stability to withstand the strains and compressive loads imposed thereon.
Other objects and advantages more or less ancillary to the foregoing, and the manner in which all the various objects are realized will appear in the following description, which, considered in connection with the accompanying drawings, sets forth the preferred embodiment of the invention.
Referring to the drawings:
Fig. l is a view in perspective of the improved carton;
Fig. 2 is a transverse sectional view thereof, the section being taken on a plane indicated by the line 2-2 in Fig. 1;
Fig. 3 is a vertical sectional view of the carton, the section being taken on a plane indicated by the line 3-3 in Fig. 1;
Fig. 4 is a vertical sectional view shown upon an enlarged scale through the base of the carton; and
Fig. 5 is a similar sectional view through the upper portion of the carton.
Referring first to Fig. 1, the carton which is chosen herein as merely illustrative of one of the types of carton customarily employed for goods of symmetrical form, comprises generally a prismoidal body embodying side walls 10, a cap 11, and a base plate 12 having rails or skids 13 mounted on the outer face thereof. The cap and base plates 11 and 12 are formed with folded edge portions constituting flanges 14 which are refolded and bound by wire strands or metallic straps or bands 16.
As will be seen in Figs. 2 and 3 the inner face of the base plate 12 is provided with cleats 17 disposed in spaced parallel relation with each other and at right angles to the outer rails or skids 13. The cleats and skids are preferably formed of wood and are spiked together to form a frame of suflicient rigidity to support the weight of the load imposed thereon when the canton is tilted on one edge of the base as frequently occurs in handling. The skids are of requisite thickness to accommodate the entry of the forks of a lift truck and are of suflicient length to overlie the corners of the corrugated carton. In addition to the stability afforded by the novel structure of the base the skids also prevent the corrugated paper base plate 12 from coming into contact with the floor, thus preventing the admisison of moisture to the interior of the carton.
The cleats are drilled to provide openings 18 for the reception of bolts disposed for engagement with certain apertured parts of the merchandise packed within the carton, for example, the legs of a refrigerator or washing machine. When the holes in the machine parts overlie the skids, the drilled openings in the skids may be counterbored to receive the heads of the bolts.
The ends of the cleats and the side walls of such of those as lie adjacent the inner faces of the side walls of the carton are disposed in abutting relation therewith and support the end wall of a corrugated paper liner 19 which extends to the top of the carton flush with the top of the folded flanged portions of the side walls. The upper edge of the liner is telescopically engaged by depending flanges 20 of a cover plate 21, the flanges 26 being inserted, during assembly, between the inner faces of the side walls 10 and outer faces of the linef 19. The cover plate engages the cap 11 thus holding the cleats and the thereof when like carthereon.
5 the ends of the side 22 folded down against the body of the carton and enveloped by the flanges 14 of the cap or base which are refolded thereover and inserted between the inner faces of the flanges 22 and the contiguous faces of the side walls 10. The body of the carton is fabricated from a rectangular blank which is scored and folded to form the side walls, one of which may be somewhat wider than the others to provide a flap for stitched or tapered securement with the contiguous panel.
From the foregoing it will be recognized that a large variety of articles of the type that may be bolted to the bottom frame work may be packed for shipment in a carton of the character described above, that the interlocked end covers will prevent separation thereof from the side walls of the carton, that the design will preclude the admission of dirt and moisture to the interior of the casing, that the liner will reinforce the side walls of the carton and prevent collapse thereof in the event the carton is upended, and that the wood or metallic frame in the base of the carton will resist deformation thereof, safeguard the merchandise, and facilitate handling of the package with ease and dispatch.
Although the foregoing description is necessarily of a detailed character, in order that the invention may be completely set forth, it is to be understood that the specific terminology is not intended to be restrictive or confining, and that various rearrangements of parts and modifications of detail may be resorted to without departing from the scope or spirit of the invention as herein claimed.
1. A corrugated paper carton for heavy articles of manufacture comprising a rectangular corrugated paper base, upwardly directed side flanges thereon, opposed side and a center ooden cleat on the upper face of said base having bolt holes therein, opposed side and a center wooden skids on the lower face of said base arranged at right angles to said cleats and aflixed thereto, corrugated paper side walls upwardly directed flanges thereon disposed within said base flanges and in abutting relation with the ends of said cleats, said side wall flanges being enveloped by downwardly folded edge portions of said base flanges, metal bands compressively engaged with the folded base flanges, a corrugated paper liner in the chamber defined by said side walls disposed in spaced relation therewith, a cap on said liner, depending flanges thereon, downwardly directed flanges on the upper ends of said side walls, a top cover, and bolts in the bolt holes in said cleats arranged to hold the article of manufacture in a fixed position within the carton.
2. A corrugated paper container for heavy articles of manufacture comprising a paper base, upturned flanges thereon, parallel wooden cleats on the top thereof arranged on the opposed sides and in the center thereof, parallel wooden skids on the bottom thereof arranged on the opposed sides and in the center and at right angles to said cleats, corrugated paper side walls, top and bottom flanges thereon, the bottom flanges being folded in interlocked relation with the flanges on said base, a metal strip circuma'mbient said flanges, the inner walls of said side wall being disposed in abutting relation with the ends of said cleats, a paper liner disposed in spaced relation with said sidewalls, a cap on said liner, depending flanges thereon telescopically engaged with said liner, a top cover, and bolts in said cleats for holding the merchandise in the carton in fixed position therein.
