Oct. 6, 1953 P. BLUM CIRCULAR WOOD BOX Filed July 1, 1949 nwE/v'mR Paul L, B/um Af/omey Patented Oct. 6, 1953 UNITED STATES PATENT F ICE;

i This invention relates generally to the constriiction of wooden boxes and is directed primarily to improvements in circular wood Boxes or the character used for thepacking oi? heads of cheese.

The ccns'true'tion of round cheese bexes fairly standard, each box consisting of a bottom and a tap. Both the bottom and top are made substantially the same manner in that each consists er a circular end Wall of wood and "a side wall fn'a'de of at least two ia-yers of lamination's of wood veneer which are bent around the end wall and secured thereto by nails or staples. By reason of the use of nails or staples in maltin'g boxes of this character it is necessarfy that the Walls be farmed of relatively heavy or thick material, particuiarly the end Walls in the edges of which the securing nails are driven. such end walls are fairly thick the hoards of which the "end walls are made will split 'or there is a possibility of the securing naiis passing th-reug'h at an angle and projecting either from the top or bottom surface of the end wall.

'-I 'he present invention has for a principal ob- 'ject to prev-ids a new and novel method of securing the side wallsof the body and top of a cheese box to the end alls which they enclose or encircle, whereby a streng and rigid construction is obtained and at the same time use may be made of boards for the circu-lar endwalls and of veneer sheets for the side Walls, of materially lighter or thinner construction than the corresponding pieces at present made use of;

Another object of the invention is to provide animbroved means of securing the side walls and end walls together in a circular box of the character stated, Without theuse of nailsdriven through the side Walls into the edge of the end wall as is the present practice so that the possibility of splitting the boards of which the end wall is made up, is entirely eliminated.- I

Still another ebiect of the invention is to provide a means fer securing the laminated wood sheets forming the sidewall of such a circular box or forming the Wall for the lid thereof, to the edge of the end wall which such laminated sheets encircle, by means of a metal band which is first placed around the edge Or periphery of the end Wall and which is provided with outwardly directed spurs or securing elements which are forced through the veneer material forming the side Wall and clinched to hold the side Wall firmly inposition against the edge of the end wall which it encircles.

In the bottom it the bottom or end wall is designated I2 and such wall comprises a plurality of boards a which are joined together in edge to edge relation and cut to the usual circular form. The side wall for the bottom it is designated 13 and this comprises two strips of wood veener b which are laid one over the other with their ends slightly overlapped as indicated at c and these veneer strips are then bent around the end wall IE to enclose or encircle the latter and in the customary manner of forming boxes, nails, not shown, are then driven through the wall i3 into the edge of the bottom or end wall 12 to secure the side wall [3 to the end wall The ends of the veneer sheets are then brought into overlapping relation as illustrated and are joined together by securing nails or staples It.

The lid or cover is constructed in a similar manner to the bottom part of the box except that the diameter is slightly larger so that the the lid will receive the open top of the bottom part Ill. The lid as here shown comprises the end wall which is generally designated 16, and the encircling side wall H, such end and side wall being formed, as stated, in exactly the same manner as the bottom.

In view of the fact that the end wall and side wall for the bottom and top portions of the box are constructed in the same manner it will be understood that wherever, hereinafter, reference is made to an end wall or a side wall, either the end wall and side wall of the bottom part of the box or of the top part is meant.

In carrying out the present invention there is provided a band 18 of suitable length, formed of sheet steel of the desired weight or thickness, which band is of channel cross section as shown in Figures 5 and 6 and comprises the web or bottom part I811 and the edge flanges ieb. This channel strip of material is made of suficient length to completely encircle the end wall with a slight overlap of the ends as indicated at I 9. The overlapped ends are secured together and to the edge of the end wall by means of a nail or staple 20.

The center or web portion |8a of the channel band is punched or cut through at spaced intervals throughout its length along the two converging lines 2i whereby to form a substantially triangular, sharply pointed spur 22. This spur which is cut or punched from the web portion of the band, is bent to extend outwardly at right angles to the outer side of the Web portion, being attached at the base of the triangle in the plane of a flange i819.

When the band is applied to the circular end wall, it is applied so that the plurality of spurs '22 will extend outwardly from the plane of-the inner surface of the end wall as shown in Figures 5 and 6, that is, when the band is placed around the end wall which is carried by the bottom part of the box the spurs will be in the plane of the top surface of such wall and when the band is applied to the wall is forming a part of the lid or cover the spurs will be in the -plane of the undersurface of such wall.

the wood to be substantially flush with the surfaces over which they lie, by the application of 4 suitable pressing rollers or other suitable means.

After the spur carrying band has been applied to the edge of the end wall the side walls or hands of veneer, after being placed one exactly on top of the other except for the end overlap as previously described, are then rolled and pressed onto the protruding points or spurs 22 which perforate the veneer walls, the ends of the points coming through slightly or projecting beyond the outer side of the veneer wall. The spurs or points are, of course, initially formed of suitable length to insure the projection of the points a slight distance beyond the outer side of the wall so that such points may then be bent over or clinched as indicated at 22a. The walls 13 and I1 of the lower part and the cover of the box, when rolled onto the points with the edges of the walls flush with the outer surfaces of the end walls, will be perforated and locked in place by the points at a distance from the outer surface of the end wall equal to the thickness of the end wall. After such application of the wall bands or veneer for the bottom or cover part of the box, the overlapping ends of the veneer bands are tacked together by the tacks or nails 15, as previously stated, in the conventional manner.

In the present invention, because the many steel points or spursrare thin, they decrease the tendency to split the veneer walls and also because they enter the wall relatively far from the edge or the veneer band and clinch so efiectively, it is possible to decrease the thickness of the veneer band used in the box and cover. Thus it will be seen that by the employment of the present invention the wood pieces used for making the end walls may be made of materially lighter or thinner character than those at present used, where nails are employed for securing the veneer bands to the end walls and, for the reasons above stated, the veneers making up the bands may also be of materially less thickness than what is at present used.

It may be necessary in a very large heavily laden box, using the present invention, to resort to thicker end wall material and heavier and thicker veneers or bands to obtain the necessary strength of box to carry the load safely. In such event, however, it is still claimed that a saving in material for both the veneer walls and the end walls is effected to hold the load over what would be required for a corresponding load in a box of conventional type of construction.

With the present invention it is also possible to make round wood veneer walled boxes with a substantial saving in weight and material without sacrificing the strength and rigidity or appearance of the finished product. This is proven by the fact that the average conventional cheese box of a well known'make weighs 4 pounds, while a box of the same make and capacity using the present invention in its construction weighs very close to 3 pounds. The new type of'box using the present invention in its construction, weighing two-thirds as much as the old, still is capable of performing the same service fully as well as the heavier conventional package.

I claim: 7

In a box for circular cheeses end walls and a side wall, one of said end walls constituting a permanent bottom and the other a removable cover, each of said end walls comprising several flat wooden pieces disposed in side edge-to-edge relation, a metal band of U-channel in cross section encircled about the outer edges of said pieces with the said edges snugly engaged in the channel thereof, spurs struck out from the web of said band and projecting laterally outward in the plane of the upper side flange thereof, said side wall comprising two sheets of wooden veneer, one overlying the other, encircled about the bottom wall and having their side edge portions overlapped, fastenings engaged through the overlapping edge portions of said sheets, said spurs being passed through the bottom edge portions of said sheets and overturned to secure the sheets and the bottom wall together, and a band of the veneer encircled about the bottom end portion of the box and having a width to overlie the overturned ends of said spurs.
