6 Claims. Cl. 206-46) This invention relates to cathode ray tube shipping cartons.

Cathode ray tubes, in shape, are characterized by having a long tubular neck portion terminating in a flaring portion with a relatively substantially flat face plate over the wide end of the flare. The flared portion may be circular or rectangular in cross section.

These tubes, in accordance with prior art, are shipped in containers, parallelepiped in form, with the neck portion of the tube confined in the containers by suitable vertical interlocked partitions and with the juncture of neck and flare supported by a horizontal centrally perforated cardboard. Additional side and face plate protecting cardboards were utilized to ensure against injury to the cathode ray tube.

It is an object of the present invention to simplify the packaging of such tubes by eliminating some of the cardboards previously used, and by reshaping other cardboards. This results in a saving of material over the prior art, and yet afi'ords at least the same degree of protection to the tube within the carton as in the prior art. Also with a lesser number of parts, savings are elfected in assembly of parts and in space necessary to stock the parts.

For a fuller understanding of my invention, attention is directed to the accompanying drawings in which Fig. l is an exploded view of my novel container with its separating cards.

Fig. 2 is an enlarged end view of a portion of the material utilized in the manufacture of the container, and

Fig. 3 is a perspective view of a packaged tube, with parts of the container open to expose interior portions of the package.

In said figures, the container is shown in the form of a carton 10. This carton is shown as made of conventional double wall corrugated cardboard, as shown in greater detail at 11 in Fig. 2, with four rectangular sides 12, 14, 16 and 18 and top flaps 20, 22, 24, and 26. The bottom of the carton has flaps similar to flaps 20 to 26 and these lower flaps are glued to one another in folded over position as is conventional practice. To package the tube there is employed a pair of vertical partition walls 28 and 30, a pair of combined vertical partition and glass breakage protecting stepped wall structures 32 and 34 and a cover cardboard section 36. The partition walls 28 and 30 are rectangular in shape, substantially of a width to reach across the width of the carton and of a height at least a little greater than the length of the cathode ray tube neck. They are each further centrally provided with two slots 38 extending about halfway down the walls, these slots being spaced apart substantially the diameter of the tube neck.

Each of the stepped walls is made in four portions. The lower portion 40 constitutes a vertical partition wall and is of a height substantially equal to the height of partition wall 28 or 30 and provided with upwardly extending slots 42 of the same depth as the slots 38 but spaced about twice as far apart to allow for considerable carton.

freedom of insertion of the tube neck into the assembled carton. The width of the portions 40 is substantially equal to the corresponding transverse dimension of the The stepped wall member is also provided with a second vertical wall 44 which has a reversely bent inwardly turned flap 46. The flap is resiliently held by reason of the nature of the corrugated cardboard. The wall 44 is of a size to fit from edge to edge against a corresponding wall, as wall 12, 'of the container, with the upper edge of the wall 44 substantially at the upper edge of the wall 12, and maintained there notwithstanding the subsequent closing of the cover flaps by the resiliency of the cardboard at the bends. Since the flap 46 is directed away from the side of the wall 44 which lies against the side wall of the carton, it does not interfere with the snug fit of wall 44 against the carton wall, thereby giving better reinforcement for the carton wall than were the flap turned outward. Moreover the flap 46 affords better resilient support for the tube when turned toward the tube. This wall 44 not only reinforces the corresponding container wall but also provides support for the flap 46 which additionally supports the tube at the thickened glass portion existing where the face plate is joined to the flared section. Connecting the two vertical wall sections 40 and 44 is the inclined wall 48, this wall serving to properly space apart the walls 40 and 44 and offering protection to the flaring walls of the tube. To complete the protection of the tube, there is provided the corrugated cardboard plate cover 36 of a width to fit snugly between the flanges 46 and of a length to fit snugly between end walls of the container. This cover 36 is resiliently provided with two doubly bent flaps 48 providing double thickness of material to reinforce the container and prevent injury to the cathode ray tube at the edge portion of the face plate, there being in effect three thicknesses of material present.

The package may be assembled by setting up the carton 10, interlocking partition walls 28 and 30 with walls 40, inserting the assembled wall structure into the carton, inserting the cathode ray tube, neck downward, in between the Wall sections, applying the cover plate 36 to the assembly and closing and securing the top flaps of the carton. It will be noted that only five pieces are necessary for insertion within the carton to package the tube, and each of these pieces is of simple character, easy to set up and easy to assemble with other pieces, all pieces lying wholly within the container.

Having thus described the invention what is claimed as new is:

1. A carton and insert assembly comprising a lower pair of spaced apart rectangular vertical partition walls, each of said walls being provided with a pair of spaced slots extending from an upper edge of the wall toward the bottom of the wall, a second pair of spaced apart wall members, each of the members of said second pair comprising a lower vertical rectangular wall portion with a pair of spaced slots extending from the lower edge thereof upwardly of the wall member, with the wall portion interlocked with the lower pair of partition walls, each of said wall members further comprising a second vertical rectangular wall portion parallel to its first wall portion but offset laterally and vertically with respect thereto and bearing against an inner vertical wall of the carton, and an inclined wall member joining the upper edge of the lower vertical wall portion with the lower edge of the upper wall portion, each of said partition Walls being of a height, in the plane of the partition wall, no greater than the height of its companion lower wall portion.
