PATENTEUAUGIOIHYI 3.598303 sum 2 [IF 2 GEORGE w, F z

M/VENTOR WM! ASLM ATTORNEY VARIABLE SIZED BOX FORM This invention relates to improvements in containers and more particularly but not by way of limitation to a base form or pattern which may be utilized in the construction of a box of multiple sizes.

In the packaging of goods it is usually necessary or desirable to provide a particular size box or container for storing or holding the particular goods to be packaged. For example, in a clothing store, department store, or the like, a great variety of sizes and shapes of goods are sold to customers. Generally it is desirable to package each type of goods in a box of a size for the convenience of the purchaser. As a result, the store normally maintains a stock of boxes of several different sizes, with an effort made to select the most convenient sizes for the goods. Many of these boxes are premade and require a substantial storage space. Other boxes of this type may be stored in a substantially flat condition but each box form or blank folds into only one size box and thus, a multiple number of sizes of box forms must be maintained. In addition, individuals often need boxes for packing goods themselves, such as for a gift, or the like, and it is usually difficult to find a box of the desired size.

The present invention contemplates a novel master pattern which may be folded and locked into a great number of sizes according to the most desirable packaging device or container required. The master pattern is provided with a plurality of spaced longitudinally extending lines or impressions for facilitating folding and/or cutting for various combinations for forming boxes of substantially any desired size. In addition, similar spaced transversely extending lines or impressions are provided as guides fcr folding or cutting of the pattern in the transverse direction in accordance with the desired box size. Tab members and complementary slots are particularly positioned on the master pattern in such a manner as to provide simple and efficient means for locking the folded portions of the box-in the proper position to provide a sturdy and substantially rigid construction for the box. The dimensions of the box in length, width, and height may be varied in substantially any desired relationship to provide a great flexibility of use for each master pattern. Patterns for box bottoms and patterns for box tops are of a generally similar construction with the general base dimension of the box top being slightly larger than the base dimensions of the box bottom, whereby the top may be easily disposed on the bottom. In order to provide a great number of box sizes, it is necessary to maintain a supply of-only one size master pattern for box bottoms and one size master pattern for box tops. Since each master pattern is a flat sheet for storing of great numbers of the pattern requires relatively little storage space.

It is an important object of this invention to provide a master pattern which may be folded to provide a container of substantially any desired size.

It is another object of this invention to provide a novel adjustably foldable box particularly designed for storage of great numbers thereof in a relatively small storage area.

A further object of this invention is to provide a master pat.- tern which may be folded and/or cut and locked in a variety of ways to form a multiplicity of box sizes.

Another object of this invention is to provide a master pattern for boxes which may be quickly and easily assembled to provide a box of substantially any desired dimensions.

Other and further objects and advantageous features of the present invention will hereinafter more fully appear in con: nection with a detailed description ofthe drawings in which:

FIG. 1 is a plan view of a master pattern for a box embody. ing the invention.

FIG. 2 is a perspective view of a master pattern in a partially folded position for forming a box of one size.

FIG. 4 is a perspective view of the completed box resulting from the illustrations of FIG. 2 and FIG. 3. 7

FIG. 5 is a perspective view of a master pattern in an initial position for being assembled into a box of a differing size than FIG. 5 in a further folded condition.

, FIG. 7 is a perspective view of the completed box shown in FIGS. 5 and 6.

FIG. 8 is a view similar to FIG. 5 depicting another possible size box.

FIG. 9 is a perspective view depicting the box of FIG. 8 in a further folded condition.

FIG. l0 is a perspective view of the completed box shown in FIGS. 8 and 9.

Referring to the drawings in detail, reference character 10 generally indicates a master sheet or pattern of a substantially flat configuration which may be constructed from any suitable material, such as a heavy cardboard, or the like. Whereas the pattern 10 may be either of a square or rectangular configuration, as desired, the particular representation illustrated herein is rectangular with the opposite side edges 12 and 14 extending throughout the length thereof and the opposite side edges 16 and 18 extending along the width thereof.

A plurality of longitudinally extending lines such as the lines A,, B, and C, are suitably inscribed or impressed on the pattern 10 and extending throughout the length ofthe sheet 10 in spaced relationship with respect to each other and with respect to the side edge 12. The lines A,, B, and C, may be printed on the surface of the sheet 10, may be scored thereon in any well known manner, may be perforated in the sheet 10, or otherwise indicated for facilitating the handling of the sheet 10 during the use thereof. As particularly shown in FIG. 1, the lines A,, B, and C, are mutually parallel with the side edge 12 and each defines a fold line and/or out line for a purpose as will be hereinafter set forth. The lines A,. B, and C, may be spaced apart at substantially any interval. such as at spaced intervals of 1 inch, or the like, as desired.

A plurality of similar lines A,,, B and C are provided on the sheet 10 in spaced relationship with respect to the side edge 14 in such a manner as to provide a substantially mirror image of the lines A,, B, and C, and are utilized in a complementary manner with respect thereto as will be hereinafter set forth.

A plurality of transversely extending lines such as the lines D,, E,. F, and. G, are suitably inscribed or impressed on the pattern 10 and extend throughout the width of the sheet 10 in spaced relationship with respect to each other and with respect to the side edge 16. The lines D,, E,, F, and G, are generally similar to the lines A1 8,. and and may be printed on the surface of the sheet. 10, may be scored thereon in any well-known manner, may be perforated in the sheet 10, or otherwise indicated for facilitating the handling of the sheet 10 during the use thereof. The lines 1),, E,, F, and G, are mutually parallel and are parallel with the side edge 16 and each l ne defines a fold line and/or out line for a purpose as will be hereinafter set forth. The lines D,. E,. F, and 6, may be spaced apart at substantially any interval, such as at spaced intervals on 1 inch, or the like. as desired. and are preferably spaced apart in such a, manner as to be compatible or complementary to he spacing betwe n the lines A,, B, and C,.

A plurality f similar line 2. F and G are provided on the sheet 10 in spaced re a ionship with respect to the side edge 1 in such a mann r as to provide. a substantially mirror image of the lines D,. E,. F, and G, and are utilized in a compiementary manner with r spect thereto as will be hereinafter set forth.

It is to b understood that substantially any number of the fold and/ cut lines may be provided on the pattern 10, as desire and there is no intention to limit the number of those depicted herein. although. as a practical matter the particular pattern shown in the drawings provides a great variety of possible uses for the pattern 10.

An outwardly extending tab member 20 is provided on the edge portion I6-and is preferably substantially centrally disposed thereon. A similar outwardly extending tab member 22 is provided on the edge portion 18 and is preferably substantially centrally disposed thereon. Additional tab members are cut into the pattern along three sides thereof whereby the tab members may be selectively bent or folded outwardly from the plane of the sheet 10 as will be hereinafter set forth and in such spaced relationship thereon as to provide great variety of use for the pattern 10.

For example, in the particular embodiment of the invention depicted herein and as shown in FIG. 1, tabs 24, 26 and 28 are cut in the sheet 10 in such a manner that the cut portions of the tabs extend in a direction toward the edge 12. The tabs 24, 26 and 28 are all interposed between the edge 16 and the line 0, and are preferably substantially centrally disposed therebetween. The tab 24 is disposed in the proximity of the line A,; the tab 26 is disposed in the proximity of the line B,; and the tab 28 is disposed in the proximity of the line C,. Similar but oppositely disposed tabs 30, 32 and 34 are cut in the sheet 10 with the tab 30 being disposed in the proximity of the line A.,,, the tab 32 being disposed in the proximity of the line 8,, and the tab 34 being disposed in the proximity of the line C A single tab 36 is disposed in substantial longitudinal alignment with the tab 24 and is spaced therefrom in such a manner as to be substantially centrally disposed between the lines F, and 0,. A similar single tab 38 is disposed in substan tial longitudinal alignment with the tab 30 and spaced therefrom in such a manner as to be substantially centrally disposed between the lines F, and 0,.

Referring particularly to FIG. 1, six sets or pairs of slots 56, 58, 60, 62, 64, and 66 are interposed between the tabs and 22 and are spaced longitudinally throughout the length of the sheet 10 in a particularly selected manner. The first pair of slots 56 are disposed between the lines F, and E, and very close to the line 1",. The second pair of slots 58 is disposed at the left-hand side of the line D,, as viewed in the drawing and very close to the line D,. The third and fourth sets of slots 60 and 62 are spaced from the longitudinal center of the sheet an equal distance, and are preferably spaced apart a distance complementary to or substantially corresponding to the distance between the spaced lines D,, E,, F, and G, fora purpose as will be hereinafter set forth. The fifth set ofslots 64 are disposed at the right-hand side of the line D, as viewed inthe drawing and very close to the line D,. The sixth pair of slots 66 is interposed between the lines E and F, and disposed very close to the line F In addition, six pairs of slots 68, 70, 72, 74, 76, and 78 are interposed between the edge 16 and the line G, and spaced apart in such a manner that the slots 68 are disposed between the edge 12 and the line C,; the slots 70 are interposed between the lines C, and B,; the slots 72 are interposed between the lines B, and A,; the slots 74 are interposed between the lines A and 8,; the slots 76 are interposed between the lines B and C and the slots 78 are interposed between the line C, and the edge 14. Similarly, four sets of slots 80, 82, 84 and 86 are interposed between the lines 0, and F, and are spaced in such a manner that the slots 80 are disposed between the edge 12 and the line C,; the slots 82 are interposed between the lines C, and B,; the slots 84 are inter posed between the lines B and C and the slots 86 are interposed between the line C, and the edge 14. Thus, the slots 80, 82, 84, and 86 are in substantial alignment with the slots 68, 70, 76, and 78, respectively. Four additional sets of slots 88, 90, 92, and 94 are interposed between the lines E, and F, and are spaced therealong whereby the slots 88, 90, 92 and )4 are in substantial alignment with the slots 80, 82, 84 and 86, respectively. Four sets of slots 96, 98, I00 and I02 are interposed between the lines and F,- and are spaced in substantial alignment with the slots 88, 90, 92 and 94, respectively. Four sets of slots I04, I06, I08 and I10 are interposed between the lines F and G and are spaced in substantial alignment with the slots 96, 98, I00 and I02, respectively. Six sets of slots I12, I14, I16, 118, 120 and 122 are interposed between the line 0 and the edge 18 and are spaced in substantial alignment with the slots 68, 70, 72, 74, 76 and 78, respectively,

The combination of longitudinally extending and transversely extending lines with the tabs and slots provide a multiplicity of folding and/or cutting and locking arrangements for the pattern 10 to provide a plurality of sizes of boxes, as will be hereinafter set forth. =It is to be understood that box bottom portions and boxtop portions may be assembled from substantially identical master patterns, with the base dimensions of the top portions being slightly larger than the base dimensions of the box bottom portions. The base dimensions of the top and bottom box portions is determined by the area surrounded by or enclosed between the lines A,, A D, and D Referring now to FIGS. 2 through 4, the method of manipulation of a pattern 10 for forming one particular size box is illustrated as follows: The sheet 10 is initially severed or out along the lines C, and C from the edge portion 16 to the line 0,, thus forming two flap members 124 and 126. The edge 14 is then bent upwardly along the line C, and the flaps 122 and 124 are bent inwardly along the line 0,. Similarly, the sheet is severed or out along the lines C, and C from the edge 18 to the line D thus forming two additional flap members 128 and 130. The side 12 is then bent upwardly along the line C, and the flaps 128 and are bent inwardly along the line D The end portion 132 of the pattern 10 remaining between the flaps I24 and 126 is then folded upwardly along the line 0, and the end portion 134 of the pattern 10 remaining between the flaps 128 and 130 is similarly folded upwardly along the line D The end portion 132 is then brought into engagement with the folded flaps 124 and 126 and the tabs 28 and 34 inserted through the slots 68 and 78, respectively, as shown in FIG. 4. When the slots 68 and 78 are double slots as shown herein, the respective tab is inserted initially through the first of the slots of the pair and then bent in a reverse direction and inserted back through the second slot of the pair in such a manner that the free end of the tab will be disposed in the interior of the box being formed. In this particular embodiment of the invention or in this particular size box the tab 20 is not needed and may be cut off or folded to an out-of-the-way position, if desired.

The end portion 134 is then brought into engagement with the folded land overlapped flaps 128 and 130, as shown in FIG. 3 and folded downwardly along the line E which will be in substantial alignment with the upper edge of the overlapped flaps I28 and 130. The end portion 134 is folded again along the line F in such a manner that the overlapped flaps I28 and 130 are completely covered by the end portion 134, and the unfolded portion of the end portion 134 lays flat along the upper or exposed surface of the sheet 10, as shown in FIG. 4. The tab 22 is now in a position substantially in alignment with the pair of slots 62 and may be inserted therein in the manner as hereinbefore set forth, thus locking the end portion 134 in position. It will be readily apparent that the pattern 10 is thus formed into a box bottom (or box top) of one particular preselected size.

Referring to FIG. 5 through 7, a second method of folding and/or cutting and locking of the pattern 10 is shown to provide another box size. Certain of the folding and/0r cutting lines are eliminated from the views for purposes of clarity, and the assembly operation thereof is as follows: The pattern 10 is initially severed along the lines B, and B from the edge 16 to the line E, to form two flaps I36 and 138. The outer end of each flap I36 and 138 is cut olfalong the line 0, and the flaps I36 and I38 are folded inwardly along the line 8,. The pattern I0 is then severed along the line B, and B, from the edge I8 to the line D, to form two flaps I40 and I42. The flaps I40 and I42 may then be folded along the line D-,. The side edges 12 and 14 are folded upwardly along the lines B, and B interposed between the cut portions thereof to form sides for the box. The end flaps 140 and 142 will be in an overlapped position whereas the end flaps I36 and 138 are spaced apart as shown in FIG. 6. The end portion 144 interposed between the flaps 136 and 138 may be folded upwardly along the line E, and disposed adjacent the inwardly folded flaps 136 and 138. The end portion 144 may be folded again along the G,

whereby the upper edge of the flaps 136 and 138 is surrounded by the end portion 144 and the tab 20 may be inserted through the slots 56 for locking the end portion 144 in position. The end portion 146 of the pattern interposed between the end flaps 140 and 142 is folded upwardly along the line D, and disposed adjacent the overlapped flaps 140 and 142. The end portion 146 is further folded along the line F whereby the upper edges of the flaps 140 and 142 are surrounded by the end portion 146 and the tab 22 is inserted through the slots 64. This locks the end flap 146 in position for completing the box as shown in FIG. 7.

FIGS. 8 through 10 illustrate still another method of folding and/or cutting and locking of the pattern 10 to provide still another box size. Here again some of the folding and/or cutting lines are eliminated from the views shown in FIGS. 8 through 10 for purposes of clarity and the assembly operation thereof may be as follows: The pattern 10 is initially severed along the lines A and A from the edge 16 to the line E, to form flaps 148 and 150. These flaps may be folded along the line E,. The sheet 10 may then be severed along lines A and A, from the edge 18 to the line D to form flaps 152 and 154. Each flap 152 and 154 is cut off or cut away along the line F and the flaps 152 and 154 may be folded along the line D The side 12 and 14 may be folded upwardly to form the sides of the box along the lines A and A in this position the flaps 148 and 150 will be overlapped whereas the flaps 152 and 154 will be spaced apart as particularly shown in FIG. 9. The end portion 156 interposed between the flaps 148 and 150 may then be folded along the line E and disposed adjacent the overlapped flaps 148 and 150 and the tabs 24 and 36 may be inserted in the slots 88 and 90 and the tabs 30 and 38 may be inserted in the slots 92 and 94. The end portion I58 interposed between the flaps 152 and I54 may be folded upwardly along the line D, and disposed adjacent the flaps 152 and 154.

The end portion 158 may again be further folded along the line 6 whereby the upper edge of the flaps 152 and l54 are completely surrounded by the end member 158. The tab 22 may then be inserted through the slots 66 for locking the end portion 158 in place thus forming the completed box position shown in FIG. 10. in this particular embodiment the tab is not necessary and may be folded downwardly to an out-of-theway position or may be cut off as desired.

The particular arrangement of cutting and/or folding lines and complementary tabs and slots on the pattern 10 provide a variety of combinations for forming boxes of a great number of sizes. As a practical matter the particular embodiment of the invention depicted herein permits a combination of 51 possible box sizes. Thus, substantially any desired box size may be provided by maintaining a supply of the flat pattern 10 wherein one size pattern 10 provides box top portions, and another size pattern 10 provides bottom portions.

From the foregoing it will be apparent that the present invention contemplates a base form, blank, or master pattern which may be folded and/or cut and locked into a great variety of substantially rectangular shapes for providing substantially any desired size for a box, carton, or container. The master pattern is premarked or impressed with folding and/or cutting lines and is provided with a plurality of particularly spaced and arranged complementary tabs and slots for locking the folded sheet into a variety of positions for forming rigid and substantial boxes or containers.

Whereas the present invention has been described in particular relation to the drawings attached hereto, it should be understood that other and further modifications, apart from those shown or suggested herein, may be made within the spirit and scope of this invention.
