Broderick, New Brighton, Staten Island, N. Y., assignor to Reynolds Metals Company, New York, N. Y., a corporation of Delaware Application September 9; 1937, Serial No. 163,142 7 Claims; (01. 229-16) The invention relates to a cake box.. , The object of the present invention is to pro vide a strong, practical and attractive cake box ,of simple and comparatively inexpensive con 5 struction, which may be easily set up and ar ranged for use, and which after assembly is adapted to be collapsed to a ?at condition for shipping or storing. A further object of the invention is to provide scored one-piece blank from which the box is formed. In the accompanying drawings in which is illustrated the preferred embodiment of the in vention, l designates a die-cut and die-scored 5 one-piece blank constructed of cardboard or other suitable material, and preferably reinforced and ornamented with a layer of metal foil, but any other suitable material may, of. course, be 10 a hexagonal cake box formed by die-cutting and ' employed in the construction of the blank. The 10 die-scoring from a one piece blank and provided blank is die-scored at 2 to form a hexagonal at diametrically two opposite sides with perma bottom 3 which is connected at one side with a nently connected parallel side walls and having hexagonal top 4 by a side wall 5 formed integral , at the other four sides interlocking wall-forming with the top and bottom of the box. The top 15' ?aps and provided also with closure ?aps hinged of the box is die-scored at 6 and the die-scoring 15 to and forming extensions of said permanently I 2 connected parallel side walls and foldable over and reinforcing the interlocking ?aps and en tirely concealing the same to present a smooth attractive appearance at the sides where the box may be opened to obtain access to its con tents. . ’ Another object of the invention is to provide simple, practical and e?icient frictional locking 25 means for securing the closure flaps over the interlocking ?aps adapted to enable the closure flaps to be readily secured in their closed posi tion and capable of enabling the cake box to be readily opened without tearing or otherwise in 30 juring the same. . With these and other objects in view, the in vention consists in the construction and novel combination and arrangement of parts herein after fully described, illustrated in the accom 35 ,panying drawings and pointed out in the claims hereto appendedfit being understood that vari ous changes in the form, proportion and minor details of construction, within the scope of the claims, may be resorted to without departing 40 from the spirit or sacri?cing any of the advan tages of the invention. Figure 1 is a perspective view of‘. a cake box constructed in accordance with this invention ' ' Figure 2 is a horizontal sectional view~of the same. ' Figure 3 is a vertical sectional view on the line 3—3 of Fig. 2. ' . Figure 4 is a similar view taken on the line 4—4 of Fig. 2. ' - ' Figure 5 is a plan view showing the box col lapsed. 55 . Figure 6 is a plan view of the die-cut and die ' for hinging integral bottom and top interlocking ?aps 1 and 8 to the bottom and top of the box. The blank is provided at the side of the top 4 2o diametrically opposite the side wall 5 with an integral side wall 9 hinged to the top- by the scoring 6 and extending from the top wall 4 and provided with an attaching ?ap l0 hinged to the side wall 9, the hinge connection being formed 25 by scoring II. The attaching ?ap I0 is secured by suitable ‘adhesive or other means to the upper face of the bottom 3 at the side diametrically opposite the side wall 5 whenvthe blank is assem bled to form the box. In assembling the blank to form the box the side wall 5 is swung up wardly to a vertical position perpendicular to the bottom 3 and the top 4 is swung to a position‘ over the bottom 3 in parallelism with the same and the side wall 9 is swung downwardly to a 35 position perpendicular to the bottom and top of the box. The attaching ?ap is then secured to the upper face of the bottom of the box. This provides parallel side walls at spaced points at diametrically opposite sides of the box. In the drawings: and shown arranged for use. de?ning the hexagonal contour of the bottom and top 3 and 4 forms hinge joints or connections ' 40 The interlocking ?aps ‘I and 8 are connected to the sides of the top and bottom between the side walls of the box and each of the interlocking flaps is provided at one end with a cutaway por tion l2 and has a substantially lobe-shaped 45 tongue 13 located at the inner end of the cutaway portion and rigid with'the interlocking flap. The _ interlocking'?aps of the bottom and top are re- ‘ versely arranged and are adapted through their hinge connection with the top and bottom 3 and 50 4 to be swung into interlocking engagement in a vertical position, thereby forming walls for sub stantially closing the sides of the box between the walls 5 and 9 and con?ning the contents of the box within the same. - - 2,112,879 The parallel side walls 5 and 9 are‘ provided at vided with means for securing it to the bottom wall, interlocking ?aps arranged in coacting pairs their ends with integral extensions forming clo sure ?aps l4 and i5 and hinged to the side falls and extending from the bottom and top of the box at the sides thereof between said walls, the 5 and 9v by lines of scoring‘ l6 and I1 and-pro vided at their outer ends with hinged extensions members of ‘each pair of interlocking ?aps being l8 and I9. The hinge Joints of the extensions I8 ' provided with means for engaging each other, and closure ?aps extending from the ends of the and I! are formed by scoring 20 and 2|. The closure ?aps are adapted to be folded over the interlocking ?aps and the extensions II and said walls and hinged to the same andfoldable over the interlocking ?aps and having friction fitting portions insertable between the adjacent ends of the pairs of interlocking ?aps. ‘\ally engage each other and also the contiguous . 3. A hexagonal box comprising a hexagonal is are insertable between the adjacent ends of 10 the-pairs of interlocking flaps and they friction ends of the interlocking ?aps whereby the 010- _ bottom, a hexagonal top, parallel side walls per sure ?aps are securely retained in their closed 15 position and at the same time are adapted to, be readily opened without tearing or otherwise in juring ‘the box to obtain access to the contents thereof.

The box may be ornamented in any desired manner and the vtop may be, as illustrated in the accompanying drawings, provided with openings 22 of segmental or other form for ‘enabling the contents of the box to be .viewed by prospective purchasers. After the attaching ?ap III has been secured to the bottom of the box the‘blank is assembled and other. ' > . 4. A hexagonal box comprising a hexagonal 20 bottom, a hexagonal top, side walls connected with the top and bottom of the box at spaced points, interlocking ?aps extending from the top and bottom of the box at the sides of the box be tween the said walls, and closure ?aps extending from the said‘walls and foldable over the inter locking ?aps. 5. A hexagonal box comprising a hexagonal it may be shipped in the flat collapsed condition ' bottom, a hexagonal top, side walls connected 30 with the top and bottom of the box at spaced 30 illustrated in Fig._ 5 of the drawings and it is also adapted to be easily and quickly set up for use. When the closure ?aps are folded over the inter locking ?aps they reinforce the interlocking flaps and strengthen the box at the sides provided with the interlocking flaps and at the same time they completely cover and conceal the interlocking ?aps and contribute to the production of a strong attractive box. The interlocking [?aps sti?en the box when the outer closure ?aps with their fric tion ?tting marginal edges are in place over- and covering and concealing the interlocking ?aps. What is claimed is: 1.
