Sz'dne 1/ Cbnescu BY ATTORNEY COMBINATION BOX AND WRAPPER This invention relates to a cardboard folding box construction and is an improvement on my L S Pat Nos 2,4l4,854 and 2,777,628.
In addition to the improvements of the folding box construction, the invention also comprises the combination of the folding box and an attached sheet of wrapping paper of the proper size and in the desired position to wrap the box after the box has been filled and the cover has been applied.
After extensive use of the boxes constructed in accordance with my aforesaid patents, l have found that added strength is required at the comers in the setup position in order to give the folding box the strength of a setup box so that the folding box will stand up better during the hazards of transportation. I have also found that the comers should be strengthened to prevent the comers from tearing when the box is set up and that the front lap should also be reinforced.
It was, therefore, necessary to correct such defects by the addition of an extra flap glued at the corners of the box to give the comers extra strength at the same time reinforcing the front lap. I have also found that reinforcing the front lap of the box prevented the front lap from returning to its original flat position.
Another problem of the retailer is the wrapping of the box after the articles are inserted and the cover is put in place. The person wrapping generally tears too much paper from the paper roll and seldom centers the box properly on the wrapping paper. Thus, wider wrapping paper sheets are used and a great deal of paper is wasted.
l have solved this problem by using the exact width and length of wrapping paper'required for the particular folding box and have spot glued the sheet of wrapping paper to one face of one-half of the box in the exact position required to properly and neatly wrap the box. This saves time of the person wrapping, paper for the retailer and makes a perfectly wrapped box. Furthermore, the edges of the wrapping paper are protected in its folded and stored condition by the edges of the folded box. Thus, the box, and paper in the required position on the box, is in the same place ready for wrapping and consequently saves the time of the wrapper and storage space for the retailer.
I have retained all the other advantages of my prior constructions as mentioned in the above-identified patents.
For a fuller understanding of the nature and objects of the invention, reference is had to the following detailed descrip tion, in connection with the accompanying drawings, in which:
FIG. 1 is a perspective view of the combination bottom half of a top load folding box in flat or knock-down condition and sheet of attached wrapping paper for wrapping the box when filled and the cover applied, the dot-dash lines indicating the box in its setup condition;
FIG. 2 is a plan view of a blank for my improved folding box tray member;
FIG. 3 is a plan view showing the blank with the panels in folded condition lying flat;
FIG. 4 is a fragmentary section taken on the line 4-4 of FIG.
FIG. 5 is a fragmentary section taken on the line 5-5 of FIG.
FIG. 6 is a fragmentary section taken on the line 6-6 of FIG.
FIG. 7 is a view similar to FIG. 3 showing the side flap portions of the wrapping paper in overlapping relation;
FIG. 8 is a perspective view of the box in its setup condition with the side flap portions of the wrapping paper in overlapping relation; and
FIG. 9 is a partial perspective view of the box shown in FIG. 8 with the end portions of the wrapping paper in overlapping relation.
Referring to the drawings, 10 is a blank from which the body member 11 is formed. Crease lines 12, 12 and 13, 13 outline side panels 14, 14 and the end panels 15, 15, leaving rectangular corner panels 16 divided by the diagonal crease line 17 to define segments 18 and I9, the segments 19 being notched or recessed, as shown at 24 for purposes which will appear more clearly hereinafter A flap 20 extends from segment 18 and is notched or recessed at 25 with its outer end 27 sloped inwardly and narrower than panel 14 for the purpose as hereinafter described. From the end panels l5, 15 there are extended flaps 21, 21 defined by the crease lines 22. Flaps 21, 21 are slightly narrower than panels 15 and have S-shaped incisions whose axial line is generally directed to diverge towards the center portion of the extreme outer end 26 of flap 21 and on a line from the end of the S-shaped incision 23 along crease line 28 to a point adjacent the outer edge 26 at the center of flap 21. The extending flaps 21 have their opposed edges angularly cut, as shown at 29 so that the extreme opposed ends 30 are shorter than the width of the central portion for the purpose as will be hereinafter described.
The blank 10, thus provided, may be fed through a folding machine, during which operation applicators apply a film of adhesive 31 to the segments 18 of corner panels 16 and panels 20, as indicated by the stippled portions, both as applied and when folded, and then the blank is fed through a folding device to hinge the panels 14, 14 about the crease lines 13, 13 to bring the adhesive 31 in contact with the panels 15, 15 and panels 20 in contact with flaps 21.
At this stage, the blank is run at right angles through a folding device, and as an incident thereof an applicator applies an adhesive film 32 at the central portion of flap 21 between the incisions 23 and the crease lines 22 and crease lines 28, as indicated by the stippled portions, both as applied and when folded. as shown in FIG. 2. Thereupon, the flaps 21 are folded about crease lines 22 to bring flap 21 over the panels 15, and connect the flap 21 at its medial portion and between the S- shaped incisions 23 and between crease line 28 and crease line 22 by engagement of the adhesive film 32 with the body of the panel 15. While glue is preferred, other fastening means may be employed.
A sheet of wrapping paper 35, slightly less in width than the length of the box in its collapsed and folded condition and long enough to be wrapped around the box when set up with its cover in place with a small overlap, is spot glued to to one face of the box, either the top or the bottom, but preferably the bottom panel, so that the wrapping paper is in the correct position to overwrap the box.
In storing the boxes with the sheets of wrapping paper attached, the boxes would be in collapsed or knocked down condition, as shown in FIG. 3, and each side of the wrapping paper is folded over the collapsed box to take a minimum of space. It should be noted that in the collapsed condition, as shown in FIGS. 1 and 3, the outer side edges of the box overlap the side edges of the wrapping paper 35 thus the edges of the wrapping paper are protected against damage. When the box is set up as shown by the dot-dash lines in FIG. 1, the wrapping paper is wide enough to cover the sides of the box so that the box is completely wrapped, both length and width, without any waste of wrapping paper.
The box cover (not shown) is identical in construction to the bottom container heretofore described except that it is slightly larger than the bottom container so a that it will easily fit upon the bottom container.
The area of adhesive film 32 creates a definite break at the crease lines 28, thus definitely controlling the bending and also increasing the strength of the glued parts of the box at this portion. The incisions 23 serve the same purpose as set forth in my previous aforesaid patents.
When the adhesive films 31 and 32 have dried, the traylike segment may be set up by lifting the opposed outer edges of the panels 14 adjacent crease line 12 while simultaneously lifting the end of the box at crease line 22. Thus, by a simple single rapid motion, the box or traylike segment is easily and quickly set up. It will be found that the angularly cut edges 29 of the flap 21 will slide over'the recessed edge 24 and the ends of flap 21 will overlay the segments 19 of the corner panels 16. The edges 24 and 25 are recessed to accommodate the thickness of the cardboard so that when the comer segment 19 is folded against the corner segment 18 there will be no bunching of the cardboard. Since segments 18 are glued to the outer ends of panel and segments 19 lie against segments 18 and are held in their upright positions by the folded over flap 21, a strong and rigid comer is created which has the strength and rigidity of a setup box. In fact, the upper' corner of the box actually has five plies of cardboard comprising the ends of flaps 21, panel 20, segments 19 and 18 and end panel 15 and the lower comer has three plies of cardboard comprising segments 18, 19 and end panel 15. The glued panel 20, while strengthening the upper comer, provides sufficient rigidity to the ends of flaps 21 aiding to prevent the flaps 21 from returning to their original flat position and creating a double layer edge at the comers where wear generally takes place and durability is required. There is ample frictional action to temporarily wedge the free ends of the flap 21 in a deflected condition to facilitate directing the free edges over the recessed corner edge 24. The arcuate corner edges of the flaps 21 combine to direct the flap 21 into locking engagement over the segment 19 to bring the segment 19 into engagement with the segment 18. The double ply thickness, comprising panel 20 and the outer end of flap 21, creates a stronger free end edge 30 for the flap 21 so that there is greater frictional engagement of the free end edge 30 against side panel 14 to better maintain flap 21 in its setup position.
The hinge cuts or incisions 23 and central crease lines 28 of divergent character, minimizes the spreading of the flap ends 30 thereby also minimizing the stress on the medially connected portion of the flap 21. This enables me to successfully use glue for connecting the flap 21 to the panel 15.
The reason for the employment of the hinging cuts in the form of S-shaped incisions and their location and the stresses incident to the various parts is fully set forth in my previous aforesaid patents as well as certain definitions and other advantages which need not be herein repeated.
If it is desired to return the setup box to its original flat folded condition, the cut edges 29 are lifted and flap 2] is pressed downwardly thus with a simply single motion the box is readily collapsed.
