vThis invention relates to improvements in cartons of the folding type and referred to in the trade as of a "knocked down" construction from which the cartons are assembled for use.l
In the past there has 'been'provided hollow wall cartons such as disclosed in applicants Re' issue Patent No. 21,158 dated July 25, 1939, and on which construction the present application is an improvement. As will be readily appreciated from the above patent hollow wall cartons or boxes provide safeguards and advantages not possible with the ordinary carton, even though said cartons are provided'with double thickness walls. It is frequently desirable to provide a carton or box which is relatively shallow compared with the articles packed therein,.wherefore, said articles extend abovethe carton walls and the carton and the articles therein are to be covered by a cover which will enclose the carton as well as the articles. In this case it is necessary that the cover extend materially above the carton to enclose the articles above the carton and at the same time provide` the cover with sufiicient strength that it will not be crushed and forced into contact with the enclosed articles.
It is, therefore, one of the principal objects of this invention to provide a cover for hollow wall cartons wherein the cover is considerably deeper than vthe carton and wherein means are provided for limiting the relative movement of the cover to the carton.
Another object of this invention is to provide an internally shouldered cover for a carton or box.
A further object of this invention is to provide, as a unit, a hollow wall carton and a hollow wall cover of different depths but adapted to Atelescope one with the other and with the hollow walls of said carton and coverv extending from one another whereby thearticles within the carton and coverare encircled by hollow walls.
It is also an object of this invention to provide, as a unit, a carton and cover wherein hollow walls extend along two opposite sides or ends thereof instead of around all the four sides as pointed out in the preceding paragraph.
It is a still further object of this invention to provide in a hollow wall carton means whereby articles may be set at angle to the outside wall line of the carton and with the inside wall line inclined whereby the over all length of the carton and it blank is held to a practical minimum.
Other objects and advantages of the present invention should be readily apparent by reference to the following specification considered in conjunction with the accompanying drawings forming a part thereof and it is to be understood that any modiilcation may be made in the exact s structural details there shown and described. within the scope of the appended claims, without departing from or exceeding the spirit ofthe in` vention.

Throughout the several views of the drawings similar reference characters are employed to denote the same or similar parts.
As was noted above lthis invention pertains to improvements in "knocked down" or foldable carton and particularlyto such carton when provided with one or more hollow walls. By hollow walls is meant, walls having an inner member and an outer member spaced from one another by a spacer integral with one of the wall members and. integral or permanently connected above specifically set forth, formed at thetinie n of cutting the blank. Adhesive 32 and 33 is then with the other wall member such as disclosed in applicants Reissue Patent No. 21,158, supra. The objects set forththat these improvements are directed primarily to a cover it will be understood, however that the cover could actually be the carton itself and what is generally, hereinafter, referred to as the carton could be the cover, and said carton and cover be telescopically assembled as illustrated in the drawings and hereinafter described. It should also be noted that reference will, hereinafter, be made to carton and cover sides and ends but it will be understood that tliese terms are used for clearness and not by way of limitation since by the term side is generally meant the longer wall of a box or carton while by the term end is generally meant the shorter side or Wall.
Specically, referring to the drawings, the blank I5, illustrated in Fig. 1, comprises a central panel I6, which in the cover would form the top and in the carton proper would form the bottom or base. The panel I6 is bounded by crease or fold lines indicated in the drawings by dash lines I1, I8, .I9 and 20. In the form illustrated the lines I1 and I9 would normally be referred to as sides from which respectively project extensions 2i and 22 foldable to form side Walls and since these parts are identical in all respects it is deemed sumcient if but one of them be described in detail, for example extension 22.
Accordingly, extension 22 comprises a portion 23 between fold line I9 and a fold line 24. which latter constitutes the top of the assembled carton'wall. The extension 22 beyond the fold line 24 is provided with parallel fold lines 25, 26 and 21 which respectively divide the extension into portions 28, 29. 30 and 3l. The portion 28 is provided, preferably for a portion at its mid-section, with adhesive 32 while the portion 3I is preferably provided throughout its length with adhesive 33.
The blank I would have the lines I8 and I 9 normally considered as the ends of the panel I6 from which projects extensions 34 and 35 which are identical in construction and a description of one of them is considered suicient for the other.
Accordingly end extension 34 is divided by a crease or fold line 36 for providing portions 31' and 38. The portion 38 has its sides notched as at 39 providing ahead of it a portion of less Width than the main body thereof and having, in effect, end tabs 40 and 4I. The base of the notches 39 is extended into the portion 38 in the form of a V cut 42 thereby, in effect. providing lugs 43 at the inner ends of the notches 39. v
Between each of the side extensions 2l and 22 and its adjacent end extensions 34 and 35 are corner pieces, each identical in construction and indicated by the reference character 44. The corner pieces are separated from their respective end extensions and side extensions but crease or fold lines 45 and 46 respectively extending from the side extension fold lines and the end extension fold lines. The corner pieces 44 are further each provided with a diagonal crease or fold line 41.
The blank yI5 is formed or cut from card or paper board material in one piece with each side extension 2| and 22 extended as side extension for a carton,
applied to side extension portions 28 and 3| whereupon the portions or said side extensions beyond the crease or fold lines 24 are folded to the position shown by side extension 2l thereby `securing side extensions portions 28 to side extension portions 23; and simultaneously securing side extensions portions 4I to the panel I5 at points illustrated by side extension 2I. The
blank is now in the position for shipment to the customer for use by him.
In order to assemble the carton part the side Walls are raised from the flat position of portion 2| of Fig. 1 to the upright position illustrated in Fig. 2. As will be seen from Fig. 2 this causes side extension portions 23 to lie normal to the sides of the panel I6 with the portions 28 secured thereto and depending from the upper ends thereof. The portions 29 bend normal along the crease or fold line 25 to lie parallel with the panel I6 with the portion 3U disposed normal to the portions 29 and the panel i6 and parallel with the portion 23. Since the side extension portion 3| was secured to the panel I6 it will be l parallel with said panel and normal to the side portion 30. With the sides in their erected posi. tions there is provided a shoulder between the panel I6 and thetop of the side portion 23 formed by the side portions 29. It will be appreciated that this shoulder may be formed at any point the top of the side depending entirely on the position of bend or fold lines 25 and 26. Also the width of the shoulder may be varied depending upon the spacing of said fold lines 25 and 26 `from one another.
The end portions 34 and 35 are now assembled to complete the carton which is eected as follows:
Corner portions 44 are folded inwardly along fold lines 46 and 45 causing each of them to yfold on itself along diagonal fold line 41. This opration causes the end extensions to fold normal to panel on fold lines vI8 and 20. It should be noted that this type of a-corner is known as a bellows corner and is not new with applicant except in combination with other parts of the blank. The end extensions portion 31 is now vertical or normal to the panel I6 and the portion 38 is now folded along the fold line 36 into the interior of the carton to lie adjacent the inner face of the portion 31. This end extension portion 38 locks the side folds in their operative position as well as locks the end wall in its operative position by causing the lugs or tabs 40 and 4I to engage behind the adjacent` ends of inner side Wall portions 30 and at the same time the tabs or lugs 43 engage behind the'adjacent ends of the shoulder or side wall portions 29 as clearly illustrated in Fig. 4.
Instead of having the side extensions 2l and 22 each terminating in gluing flaps 3| and secured tion 30 across the space extension portion 48, which takes the place of flap 3 I, and extends from the side extensions porbetween the inner wall members.
tensions 49 and 80. Since end wall extensions 49 -lo and 59 are identical in construction but one of them will vbe described in detail. Accordingly,
end wall extension 49 is provided with parallel This modified crease or fold lines 8|, 82, 58 and 84 forming end Y wall extension portions 88, 58, 51, 88 and 59. As will be noted portions l1. 88 and 89 are narrower than portions 88 and 88. Projecting from opposite sides ofthe portion 58 and substantially adjacent its outer end are tabs or lugs 80 and 8|. The portion 59 is laterally defined, substantially throughout its length. by fold lines |09 and ||0 which respectively hingedly attach to the portion 99 spacer tabs Y| The end wall portion has adjacent its opposite end projecting toward the spacers |I| locking tabs |I2 which are similar to the locking tabs 43 above set forth.
In the modification of Fig. 5 side extensions portions 89 are modified over that shown in Fis'. l by having formed therein near their/outer ends and adjacent thebottoms thereof slots 92 which, as will presently be described are means for holding the end wall in operative position.
The assembly oi' the box or carton part from l the blank of Fig. 51s substantially identical with that above set forth with respect tothe blank I8 of Fig. 1, except that the end walls are arranged to provide a shoulder in line with the shoulder of the side walls. yAccordingly after the positioning of the corners 44 as above described the end extension portion I8, is folded along the line 5| into engagement with the portion 88 whereuponl the portion 81 is folded normal to the portion 88 along the fold line 82 and the portion 88 is folded on the fold line 88 normal to the portion 81 and to lie parallel with the portion 88 but spaced therefrom. Prior to the folding of the portion I8 along the line I3 the spacing tabs HI and the portion 89 were folded upwardly, as seen in Fig. 5, normal to the portion 88 along the foldlines 84. |89 and H9, respectively, and the portion 89 now engages with the panel i8 and acts as a spacer for spacing the lower end of the portion 88 from the' portion 88 for spacing the portions 88 from the portion 58, and thereby providing inner and outer end wall sections between the panel I8 and shoulder 51. At thisM time .the lugs 80 and 8| are `snapped into the slots 82 which are positioned at the bottoms of the inner side wall sections.
As was noted above this box or carton part is arcanos li f 3 construction, wherefor a'description of one will e sumce for both, The side extension 89 is provided with parallel fold 1ines'19,.1| and 12 diyiding the .side extension into sideV extension portions 19,
14, 18 and 18. 'I'he opposite -ends of the portion .18 has connected thereto along fold'lines 11, tucking flaps 1l. Each tucking flap is provided with a fold lines 19 to provide a spacer tab 89 at the n upper end thereof. In addition the side extension portion 18 is provided substantially at the bottom thereof and at opposite ends with inclined slots 8l and 82, whose purpose will be subsequently pointed out. The portion 15 is also provided substantially at its top and near its one end-with a lug 88.
The panel 84 has projecting from its end fold4 u lines 88l and 88 end extensions 84 and 88 substantially identical in construction wherefore a description oi' one will sumce for the other. Accordingly end extension 84 has parallel fold or crease lines 86,181 and providing end wall extension portions 89. 99. 9| and 82. End wall portion 9| is latterly defined by score' or fold lines 93 and 94 which respectively hingedly attach spacer lugs 95 and 98 to the end wall extension portion9l. Cut out of the spacer lugs 98 and 98 and integral with the ends of portion 9| are tabs 91 and 99 adapted, as will readily appear. toflock end walls in assembled position.
Between adjacent edges of the end wall extensions and the side wall extensions are corner pieces 99 substantially identical in construction y to bring the side extensions 88 and 69, to the position illustrated for side 88 of Fig. 9. It is in this' position that the carton is shipped to the user who, when desiring to use same. merely lifts the I sides from their flat position to their upstanding adapted to be used with a hollow wall .carton by There is illustrated in Fis. 9 to l2 inclus-ive. a
blank and assembled carton for use with the shouldered cover above described. As there shown the carton comprises a blank 88 which provides a panel 84 bounded by crease or fold lines I8. 88. 81 and 89; -Extendingfrom fold lines 88 and 81 are side extensions 89' and 89 identical inposition as illustrated-in Fig. 10 whereupon the end 'flaps 84'and 88 are folded on their various fold and crease lines, as described in connection with the vend extension 49 of the carton or box part illustrated in Fig. 5 which will bring the tabs 91 and 99 into position to enter the slots 8| and 82. The only dlil'erence in this assembly is that after the side wall extensions 88 and 89 are in vertical position the tucking flaps 18 thereof are folded across the panel 84- and end spacer tabs vbent normal thereto to lie parallel with the base panel 84. v
It should be noted that portions 199 of end extensions 84 and 85 are of different widths as are end extensions portions 89 and 9| as between themselves. In other words portions 89 of each end extension are oi' the same width as' are portions 9| but said portions 99 of each end extension is slightly narrower than their respective portions'9l. By this construction the portions 9| will be angled to the portions 89 when in final assembly as, clearly illustrated in Fig.'11, and with the portion 9| of endl extension 84 inclining toportion .90 while the portion 9| of the .end extension 88 inclines-awayfrom the bottom of its portion 89 and beyond'its portion 99. As wasv noted above the purposes for this construction are carton to a practical minimum.
articles upon removal, for example, of the` first one, there is provided in the carton means for preventing the lower end thereof from sliding forward due to its angular position. This means conveniently takes the form of a piece of so called corrugated board |0| which is provided transversely thereof with successive undulation As is readily apparent from an inspection of Fig. ll the lowermost corner ofthe articles |00 is disposed inv the Valley between successive ridges with the bottom of the article against the forward undulation and with the rear side of the last article in the carton engaging the upper corner of the inner wall member of the hollow end wall.
, While the-standard corrugated board actually lls the need for a means for maintaining the articles in the desired position it will be understood that a stepped member may be substituted therefore.
In Figs. 13 and 14 there is shown a further modification in the construction of the blank for making an internally shouldered cover, carton or the like, which is particularly useful when a shallow construction or carton part is desired. In this construction the end wall extension |03 is of substantially uniform width from the panel end wall fold line 20 and said extension is provided with transverse crease or fold lines |04 and |05 providing end wall extension portions |06, |01
with uns construction of blank the carton part end wall is assembled as follows:
After the side walls are in position and the` bellows corners arranged the end wall extensionY |03 is partly elevated about fold line 20 whereupon the portions |01 .and |08'are partly folded about fold lines |04 and |05. The portions |06, |01 and |08 thus assume the positions illustrated in dotted lines in Fig. 14 whereupon the portion |08 is inserted behind the shoulder and inner member of the side wall and the outer end of the portion |08 dropped down to engage the panel. In other words the end wall extension |03 may, in effect, be rolled over the tops of the bellow corners after they are positioned and locked behind the shoulder portion and side wall inner member through their height. This, so called, rolling of the end wall extension is made possible by the fold line |05 working in conjunction with the fold line |04, and is particularly useful on relatively'shallow constructions.
It is believed the foregoing clearly discloses a construction for accomplishing the objects initially set forth, in that, a shouldered carton part is provided which co-operates with a hollow wall carton part in providing a completely enclosing carton which will take the usual punishment given any box or carton and will prevent damage to the goods within the carton and will not collapse under unusual adverse treatment.
