MULTIPLE COMPARTMENT BOX Filed Dec. 25, 1946 INVENTOR WI L'BUR W. HOLES ATTORNEYS Patented Oct. 4, 1949 UNITED STATES PATENT OFFICE MULTIPLE COMPARTMENT BOX Wilbur W. Holes, St. Cloud, Miim.

Application December 23, 1946, Serial N0. 718,083

12 Claims. 1

My invention relates to a multiple compartment box adapted to be shipped knocked down and readily assembled.

There are many instances where a multiple compartment box of inexpensive construction is required. In any place where removable numbers, letters, price cards, and the like are used, a multiple compartment container for storing the unused inserts is highly desirable.

It is an object of my invention to provide a novel, strong, inexpensive box made .of sheet material having multiple compartments.

It is a further object to provide a multiple compartment box composed entirely of two pieces of sheet material.

More specifically it is an object to provide a multiple compartment box adapted to be made from any inexpensive, rigidly pliant sheet material, such as cardboard, and adapted to be shipped knocked down and also adapted to be readily assembled.

These and other objects and advantages of my invention will more fully appear from the following description made in connection with the accompanying drawings wherein like reference characters refer to the same or similar parts throughout the various views and in which:

Fig. 1 is a top perspective view of the assembled box;

Fig. 2 is a transverse sectional view taken substantially on the line 22 of Fig. 1;

Fig. 3 is a longitudinal sectional view taken substantially on the line 3-3 of Fig. 1;

Fig. 4 is a bottom view of the assembled box;

Fig. 5 is a plan view of the main blank before being folded, in which score lines are shown as dotted and cuts are shown as full; and

Fig. 6 is a plan view of the filler blank before being folded in which score lines are shown dotted and cuts are shown full.

Generally speaking, my multiple compartment box is made of two pieces of sheet material, such as cardboard, to form a main blank, designated as an entirety by the letter A, and a filler blank designated as an entirety by the letter B.

As shown in Fig. 5, main blank A has a rectangular central section designated in its entirety as Al, a pair of side flaps designated as A-Z, a pair of end flaps designated as A3, and four corner flaps designated as A-4.

The central section Al has a series of relatively short longitudinal score lines made in the top surface thereof to form fold lines l0. Said Iold lines are longitudinally spaced to form transverse rows and pairs of longitudinal rows as shown in Fig. 5. Longitudinal cuts II are made along lines which are medially disposed between adjacent fold lines I!) of the various pairs and these cuts H are co-extensive and parallel with said fold lines ll. Transverse cuts B are made between the extremities of each pair of longitudinal fold lines l9 forming longitudinal wings M in opposed pairs. These wings I 4 in the transverse row second from each end of section A--l have small tab members l5 for interlocking with diminished end portions 36 of end flaps A3 as will appear later. Except for these tabs the ends of wing members l4 are cut angularly inward toward the free edges thereof, leaving small triangular cut-outs adjacent the end portions of the pairs of flaps as shown in Fig. 5.

The side flaps A2 extend outward from the sides of said central section Al and are connected integrally therewith. Longitudinal scores forming fold lines l6, l1, l8, and 19 are made in the top surfaces of side flaps A2.

The end flaps A-3 extend outwardly from the ends of said central section AI and have gradually diminishing sections 35 and diminished end portions 36. These diminished end portions 36 are adapted to interlock with tabs I5 as will appear later. Transverse scores forming fold lines 29 and 2| are made on the top surfaces of end flaps A-3, and scores forming fold lines 22, 23, and 24 are made in the bottom surfaces of end flaps A-3. Angular score lines 25 are made in the bottom surfaces of corner flaps A4.

Filler blank B is rectangular in shape and has longitudinal cuts therein to form slits 26 slightly shorter than the fold lines I B and adapted to receive the ends of wings l4 when the box is assembled, as will appear later. Pairs of longitudinally spaced transverse scores forming fold lines 21 are made in the top surface of blank B. Intermediate adjacent pairs of fold lines 21 more widely spaced pairs of scores are made in the bottom surface of blank B to form fold lines 28.

In the assembly of the multiple compartment box filler blank B is folded up on score lines 28 and down on score lines 21 to form a corrugated filler sheet with upstanding webs 29 and lower webs 3B. Wing members Id of main blank A are folded down along fold lines In to form rectanular apertures or windows in the central section A--!. Main blank A is placed over filler blank B, and wings M are fitted into corresponding slits 26 forming rigid compartment sides and bottoms, the upstanding webs 29 adjacent the lower webs 30 forming compartment ends. The side flaps A-Z are folded down on fold lines Hi to form box sides 3!. Then flaps A-Z are folded in on fold lines l8 and I9 forming an underlying supporting flap 32, and then flaps A--2 are folded in on fold lines I! to form box bottom portions 33. Supporting flaps 32 engage the bottom surfaces of lower webs 30 between the downwardly protruding ends of .wings M in the row of compartments adjacent the sides of the box, as shown in Fig. 2, and interlock between said wings l4.

Corner flaps A4 are folded in on fold lines 25 and end flaps A-3 are folded down on fold lines 29 and in on fold lines 2| to form box ends 35 and overlapping bottom sections 35 of the box as shown in Figs. 4 and 5. The diminished end portions 38 of flaps A-3 are folded on fold lines 23 and 24 to form upstanding webs 36a and 36b, said webs being fitted into the corrugations second from the ends of filler blank B, as shown in Fig. 3. The lower edge of web 36b abuts the top surface of tabs 15 on wings I4 forming an interlocking connection for holding filler blank B in position and for keeping the box rigid. It will be noted that no glue whatever is used in making this multiple compartment box. 7

It will be seen that there has been provided a multiple compartment box made entirely from two pieces of inexpensive sheet material, such as cardboard or sheet metal. After these sheets ing construction. This-construction is adapted for sheet metal material as well as for cardboard or other material which can be bent and will rigidly retain a desired form. There is no limitation on the number of compartments that can be formed nor in the size. of the box, as my invention is adapted to be used on any size sheets.

It will of course be understood that various changes may be made in the, form, details, ar-

rangement, and proportions of the various parts without departing from the scope of my invention.
