8 Claims. 1

This invention relates to the manufacture of More particularly, it pertains to improvements in the manufacture of containers comprising combination shipping. storage and display devices cut, scored, and glued from. single blanks, and thereafter folded from collapsible position and held in erect interlocked engagement by means of longitudinal bottom interlocking partitions.

Heretofore various types of cartons and containers have been utilized forpackaging materials containing heavy breakable jars lled, for example, with cosmetics', pharmaceutical preparations, shaving creams, and the like.' Such articles packed in a container are of considerable weight. They need ample protection against breakage as well as surface protection against scrufiing, scratching, or other mutilatlng effects usually produced'by having .one in contact with another. It has been customary to pack such articles in ordinary cardboard boxes, lining the inner walls, top and bottom Awith corrugated paper in an effort to offset these disadvantages but this has been unsatisfactory. In addition to the '.served and prevented in time by the handler of such containers or cartons, there is always great danger of breakage by the contents falling out age and display device from a blank of cut and scored board material which can be 4folded into container formation to provide end and side walls, inner and outer bottom and'top walls, and upper and lower longitudinal partitions connected to the outer walls with cross partitions connected to the inner walls, and in which the inner walls have slots interlockingly to engage longitudinal partitions along locking edges provided therefor.

A principal object of the. invention is the provision of an interlocked carton or container which will remain a completed unit after the same has been shipped, stored and opened and which thereafter can be utilized as a display device.

Another object of the invention is the provision of a carton such as that herein described which can be divided into upper and lower tiers by utilizing a die-cut divider without interfering with the. functions of the longitudinal and transverse partitions and which additionally functions as a supplemental reinforcing member.

Yet another object ofthe invention is the provision of a carton or container in which there is provided longitudinal and transverse partitions integral with the bottom and top walls thereof, interlocking with each other and extending from top to bottom ofthe upper and lower walls to hold those walls in reinforced and spaced apart relationship.

Other objects of the invention will in part be obvious and will in part appear hereinafter. y

The invention accordingly comprises an articlev of manufacture possessing the features, proper-,j ties, and the relation of elements which will bel exemplified in the article hereinafter descrilieil and the scope of the application of vwhichwill" be indicated in the claims. fv "j For a fuller understanding of the nature and"v objects of the invention reference should be had to the following detailed description taken in connection with the. accompanying drawings, in which:

This is a continuation-in-part of my copending application Serial No. 431,024, now Patent No. 2,347,183.

Referring more specifically to Fig. 1 of the drawings, there is indicated generally at I a die cut and scored blank preferably cut from a single web of material. Suitable score lines divide the blank into complementary side walls II, II and end walls I2, I2. To one side of these walls are inner bottom walls I3, I3 and outer bottom walls I4, I4. The inner bottom walls I3, I3 each have extensions forming bottom cross or transverse partitions I5, I and the outer bottom walls I4, I4 have longitudinal bottom extensions forming locking partitions I6, IIS.l

On the other side of the end and side walls II, II and I2, I2 are inner top walls I1, Il and outer top walls I8, I8. Extending fromthe inner topv walls I1, Il are top cross or transverse partitions I9. I9. Extending from the outer top walls I8, I8

are longitudinal

top partitions

20, 28,

One end wall I2 has an extension providing a glue ilat 2l. The inner bottom walls I3. I3 are provided with

slots

23, 23. The inner top walls I1, I'I are provided with

slots

22, 22. These slots also divide the bottom and top cross partitions I5, I5 and I8, I9 into two parts. The bottom of these slots end short of the adjacent'end walls I2, I2.

At the intersection or fold line of the outer bottom walls I4, I4 and the longitudinal bottom locking partitions I6, I8 there are provided, inwardly directed from their respective edges, cut-out portions or

notches

24, 24. y

Such a blank with glue applied to one .face of the glue flat 2I is folded centrally over upon itself and the glue flap made to adhere preferably to an inner surface of a side wall II. lIn this collapsed or knocked down condition the articles may readily and conveniently be shipped in bulk ready for erecting in interlocked position for use.

In folding such an article into interlocked position the same is rst squared and opposite'inner bottom walls I3, I3 are folded inwardly towardV each other so that the bottom cross partitions I5, I5 fall within the confines of the carton.

bottoms of the

slots

23, 23, thereby holding in erect and interlocked position the carton and partitions ready for filling.

It will be observed by reference to the drawings that the longitudinal partitions are somewhat ta pered. They are n-arrower across their free ends than at their base ends. The distance across the free ends is substantially the .same as the distance between the bottoms of the slots 23 in the panels forming the inner bottom walls I3, I3. When these free ends are inserted and the outer bottom walls pushed downwardly to bring all bottom walls into aligned position the inner walls are flexed inwardly because the tapering edges frictionally engage the bottoms of the slots and this inward flexing continues until the bottoms of the slots fall into registry with the notches 24 and the inwardly exed walls spring back into normal position as indicated in the assembled views so that they are aligned adjacent to the outer walls.

The longitudinal bottom partitions I8, I8 and bottom cross partitions I5, I5 form cells in the bottom of the carton well adapted to receive articles in the form of jars such as, for example, containing shaving cream, cold cream, or the like, and it will'be seen that all sides of each individual jar are isolated and protected from each adjacent jar. After the bottom cells have been lled, a spacer pad may be placed upon the bottom layer, thereby dividing the carton into upper and lower tiers and at the same time lending protection to the upper sections or covers of the jars. A similar tier of ,jars can then be placed upon the spacer pad whereup the inner top walls Il, I1 are folded thereover in such a manner that the top cross partitions I9, I9 point downwardly and between adjacent ja s separating the same transversely. Thereafter e outer top walls I8, I8 are folded over the inner top walls II, Il in such a manner that the longitudinal

top partitions

20, 20 come together and adjacent each other to penetrate the

slots

22, 22 in the inner top partitions, the bottoms of all partitions coming to rest against the spacer pad.

It will be noted that the top longitudinal and Y cross partitions similarly form individual cells for the top tier of jars, protecting them in the same manner as the lower tiers are protected, that is, on top and bottom as well as peripherally. The top

longitudinal partitions

20, 20 extending from the top covers I8, I8 sulciently frictionally engage each other. to be held in this position although a stripof tape can be used as an auxiliary closure element to insure that they are held thus during shipping.

Referring now to Fig. 5 it will be seen that there has been provided a cut and scored blank in accordance with the principles of the present invention as disclosed in the modification illustrated in the preceding figures. There is illustrated in this modification a blank which is of somewhat dinerent dimensions with respect to certain of the partitions and walls but in all other respects itis identical to the other modification with the exception that there are no bottom cross partitions con nected to the inner bottom walls.

This blank may similarly be folded upon itself around a central score line and the glue ap 2I similarly alxed to an opposite side wall.

As will be seen from Figs. 6 to 8, inclusive, the collapsed folded and glued together blank is erected by squaring the end and side walls and similarly infolding the inner bottom walls, infolding the outer bottom walls with the longitudinal bottom locking partitions coming adjacently together so that the notches 24, 24- interlockingly engage the bottoms of the

slots

23, 23. The carton is thus in condition for filling and after this has 'been done the inner top andouter top walls are folded respectively in that l order similarly as set forth in the preceding modification. Thus, there is formed a container, the top longitudinal and cross partitions of which, because of theirA predominant length, extend to the inner bottom container wall and the bottomlcngitudinal partition lies adjacent the top longitudinal partitions extending to theinner top wall as more particularly illustrated in Figs. '7 land 8. This arrangement provides a plurality of adjacently aligned longitudinal partitions and `spaced apart transverse partitions which hold the bottom and top walls in reinforced and spaced apart relationship.

It is not essential in all cases, depending of course upon the weight of the particular articles being dealt with, that the complete set of longitudinal partitions extend from top to bottom walls. However, it is desirable and essential to invention which, as a matter of language, might to receive said longitudinal partitions, the distancevbetween the bottomsA of the slots being less than the length of the walls which are parallel to said longitudinal partitions, and the bottom ends of said longitudinal partltionshaving adjacent locking notches interlockingly engaging the bottoms of said innerw'all slots, and the length the practical success in many respects of such cartons as those herein described for holding heavy articles, that at least one set or' the partitions extend from top to bottom so that proper` reinforced internal structurels providedlto compensate for various stresses and strains set up as well as to provide the tailored t which is imparted to such folded blanks of material. One form of such partitionarrangement is illustrated in Fig. 9. f 4

It is also within the contemplation of the invention that, regardless of length, the various adjacent upper and lower longitudinal partitions, when such are used, may alternately be staggered adjacently in aligned position more clearly as illustrated inFig. 10.

While the carton illustrated in Figs. 5 to 10, inclusive, depicts a type of container which is more suitable'for longer rather than the more nat type of articles to be packed, it does not show a spacing pad so that the container can be divided into upper and lower tiers.

However, reference to Figs. 11 and 12 will illustrate an arrangement whereby cartons having partitions extending from top to bottom canbe sub-divided into upper and lower tiers.

The dividing pad in this case is indicated generally at 25. Preferably this pad is die-cut to lockingly engaging the bottoms of said inner provide an opening 26 centrally ofthe pad and adjacently disposed openings 21 perpendicularly thereto. The opening 26 is adapted to receive both upper and lower longitudinal partitions and the openings 21 to receive transverse partitions as ilustratecl. As an aid in strengthening and lending rigidity to the carton, the longitudinal partitions may be provided with cut-out

notches

28, 28 adapted interlockingly to engage the extreme ends of the slot 26.

It will thus be seen that the objects herein- A before set forth may readily and efliciently be attained, and since certain changes may be made longitudinal of the lower longitudinal partitions adjacent said locking notches within said container being greater ythan the distance between the bottoms of said slots.
