4 Claims.

This invention relates to heavy duty master cartons of the kind used for shipping a multiplicity of small packages or articles and compris ing a tall, tubular open-ended liner of rectangular cross-section and duplicate upper and lower slip covers of corresponding cross-section fitting over the open ends of said liner with their opposing ends in abutting relation substantially midway of the height of said carton. A serious practical objection to the above type of carton is that the height of the liner prevents the packer from reaching through the open upper end of said liner to pack the packages or articles in the lower portion thereof. The principal object of the present invention is to provide a master shipping carton of the above type that will permit easy access to be had to the lower portion of the tubular liner to facilitate packing and unpacking of such portion. Other objects are to provide for the ready assembly and disassembly of the parts of the carton, simplicity and cheapness of construction and adequate strength and durability.

The invention consists in making the tubular liner in five separate sections; namely, two 00- operating channel-shaped lower liner sections that fit within the upwardly opening lower cover and terminate short of the upper end thereof, two cooperating inverted channel-shaped upper liner sections that fit within the downwardly opening upper cover and terminate short of the lower end thereof, and an intermediate side wall liner section that extends downwardly into said lower cover, seats on the upper ends of the two cooperating lower liner sections therein and extends upwardly into said upper cover into endwise abutting relation to the lower ends of the two cooperating upper liner sections therein. The invention also consists in the master carton and in the parts and in the arrangements and combinations of parts hereinafter described and claimed.

In the accompanying drawings, which form part of this specification and wherein like symbols refer to like parts wherever they occur,

In the accompanying drawings, our invention is shown embodied in a relatively tall four-sided master shipping container or carton comprising counterpart lower and upper slip type covers A and A, respectively, two cooperating channelshaped lower liner sections B and B, respectively, two cooperating inverted channel-shaped upper liner sections C and C, respectively, and a single intermediate liner section D, all of corrugated board, fiberboard or other bendable material.

Each of the upper and lower covers A and A is preferably closed by half closure flaps I along the edges of the four side walls thereof, the end closure flaps on two opposite side walls overlapping the end closure flaps on the two other opposite side walls. The outermost closure flaps of each cover have their abutting edges connected and covered by a strip of adhesive tape 2; and the ends of said outermost flaps are covered by strips of adhesive tape 3 secured to said ends and to the adjacent sides of said cover.

The channel-shaped lower liner section B comprises a bottom panel 4 and upstanding side walls 5; and the other channel-shaped lower liner member B comprises a bottom panel 4 and upstanding side walls 5. The channel-shaped lower liner member B has a snug fit in the upwardly opening lower cover A with its bottom panel 4 seating flatwise on the bottom thereof and with its upstanding side walls 5 seating flatwise against the two corresponding opposite side walls of said cover and terminating some distance short of the top thereof. The other channel-shaped lower liner member B seats in the other channelshaped lower liner member B and extends crosswise thereof with its side walls 5 seating flatwise against the other two opposite side walls of the lower cover A and with the upper edges of the

side walls

5 and 5 in flush alignment.

The inverted channel-shaped upper liner section C is similar to the lower liner section B and includes a top panel 6 and depending walls I; and the upper liner section C is similar to the lower liner section C and includes a top panel 6 and depending side walls 1'. The inverted channel-shaped upper liner sections C and C' are assembled and mounted in the downwardly openin: upper cover A in the same manner that the two channel-shaped lower liner sections B and B are mounted in the upwardly opening lower cover A, with the depending side walls I terminating short of the lower end of said upper cover. As shown in the drawings, the lower liner section B has a series of relatively large circular openings 8 in the bottom panel 4* thereof; and the upper liner section C has a similar series of relatively 1 small circular openings 9 in the top panel 6- thereof.

therein and extends upwardly into the upper cover A into abutting relation to the lower edges of the depending side walls I and I of the two inverted channel shaped liner. members C and C' nested therein.

The above master carton is particularly adapted for use in shipping a multiplicity of small packages E stacked fiatwise one upon another in horizontal rows within the tall closed liner formed by the assembled channel-shaped lower liner sections B and B, intermediate liner section B and inverted channel-shaped upper liner sections C and C. As shown in the drawings, each of the smaller packages E contains a plurality of upright rayon spools or cones F. Each package E comprises a horizontally disposed open-ended tube of rectangular cross-section having a plurality of relatively small holes H in its top panel and a plurality of relatively large holes I! in its bottom panel in vertical alignment with said relatively small holes.

Each of the rayon cones F comprises rayon yarn l3 wound upon an upwardly tapering hollow 'core ll projecting at each end from the yarn.

The rayon cones F are positioned in the tubular packages E with the small upper ends of their cores 14 extending upwardly through the small holes II in the top panels of said packages and with the large lower ends of said cores disposed in the large holes 12 in the bottom panels of said packages normally flushed with the undersides thereof. By this arrangement, the rayon cones F are firmly held in the tubular packages E out of contact with one another. The openended tubular cone containing packages E are compactly stacked one upon another in vertical and horizontal rows from top tobottom of the tall liner formed by assembled liner sections, with the small upper ends of the hollow tubular cores H of the cones F of each package extending upwardly into the large lower ends of the cores of the cones in the packages seated thereon and with the small upper ends of cores of the cones in the top row of packages extending into the holes 9 in the top panel i of the inverted channel-shaped 4 upper liner section C. In the event that the cores of the cones in the bottom row of packages are forced downward by the weight thereon, the large lower ends of these cones are adapted to seat in the openings 8.

The hereinbefore described master shipping carton is assembled and packed in the following manner: The two lower liner sections B and B are positioned in the upwardly opening lower cover A in the manner hereinbefore described and a first stack of packages E is laid in said lower liner sections with the top of said first stack terminating below the upper edges of the upstanding side walls 5 and 5' of said lower liner sections. The intermediate liner section D is then placed in position with its lower end portion fitting within the upper portion of the lower cover A and supported on the upper edges of the

upstanding walls

5 and 5 of the two nested lower liner sections B and B therein. The intermediate liner section is then stacked with packages and this stacking continued above the level of said liner to the height desired for the finished stack. The two inverted channel-shaped upper liner sections C and C are then mounted in the upper cover A in the manner hereinbefore described, after which said cover with said liner sections therein is inverted and telescoped downwardly over the exposed upper portion of the stack of packages and over the exposed upper portion of the intermediate liner section D so as to seat the lower edges of the depending side walls 1 and l of the two inverted channelshaped upper liner sections 0 and C on the upper edge of said intermediate liner section and to seat the lower edge of said upper cover on the upper edge of the lower cover A along the liner located substantially midway of the height of said intermediate liner section. The packed carton is then bound with the crossed metal securing bands or straps I5 that are locked in contracted position by suitable coupling members IS.

The hereinbefore described master shipping carton permits easy access to be had thereto to facilitate packing of the lower portion thereof. The intermediate liner section is held in place by the lower cover during the packing operation, and the upper cover with the upper liner sections therein may be quickly and easily slipped downwardly over the exposed upper portion of the completed stack and over the exposed upper portion of said intermediate liner section. The horizontal joints I1 between the intermediate and upper and lower liner sections are offset relative to the joint i8 between the abutting ends of the upper and lower covers, thereby strengthening the carton. The carton is further strengthened by offsetting the joints ll between the intermediate and upper and lower liner sections relative to the joints between the horizontal rows of packages located adjacent to the liner joints. The upper and lower liner sections cooperate with the covers to increase the strength, rigidity and durability thereof. The carton is also of simple and economical construction and may be quickly and easily assembled and packed and readily disassembled and unpacked.

Obviously, the size of the above carton and the proportions of the parts thereof may be varied for different articles without departing from the invention.

What we claim is:

l. A shipping carton comprising a relatively thereof, an intermediate liner section extending upwardly from said lower cover with its lower end disposed therein and supported on the upper edges of the upstanding side walls of said lower liner sections, and a plurality of separate upper liner sections mounted in said upper cover and having depending side walls connected to panel members and seating against the side walls thereof, the panels being superimposed and resting on the closed end of said upper cover, the walls terminating short of the lower end thereof and supported at their lower edges on the upper end of said intermediate liner section.

2. In a shipping container as defined in and by claim 1 wherein the innermost of each of the said panels is provided with a plurality of spaced openings into which the outermost reduced ends of yarn cone cores are adapted to be placed.
