Brown, Northbrook, Ill., assignor s to Container Corporation of America, Chi, cago, lll., a corporation of Delaware Application March 23, 1936, Serial No. 70,247 3 Claims. (Cl. 229-45) The present invention relates to containers particularly adapted for the packing of ice cream and other edible materials which are intended to be made up in individual packages to be eaten directly from the container. v 5 ì One object of the invention is to provide a relatively liquid-tight container capable >of being manufactured in complete form at the box plant so that the container may be shipped ñat to the 10 user and set up by him without requiring any spe the container each of which has cooperating interlocking parts formed thereon at the corners of the container so as' to secure the cover against accidental displacement. - 1 Referring more particularly to the drawing, 5 the body portion I of the container comprises a bottom 2, and side walls 3, 4, 5, and 6, all of which are preferably formed with outwardly ta pered edges'. See particularly Fig. 4. The walls 3 and 4 are provided respectively at their ends l0 cial machinery and without the use of fastening ' with flaps 3a, 3b, la, 4b. These naps are formed with conventional interlocking parts which en devices other than parts formed on the con tainer itself. l A further object of the invention is to provide 15 a simple and effective locking means for retain ing. the cover on the container, such locking means being disposed adjacent the corners of the cover and body- portion whereby the cover will be securely retained against accidental dis placement. ‘ vA further object of the invention is to locate the locking parts so that they will be disposed substantially outside of the compartment in which the food is contained whereby the food compartment proper will be substantially smooth and free from irregularities thus minimizing like lihood cf contamination by dust or other foreign matter. A further object is to provide a container of the 30 type described which will beextremely simple in form and easy to set up and use, and which will be effective for the purpose intended. To these and other ends the invention resides in certain improvements and combinations of Y parts, all as will be hereinafter more fully de scribed, the novel yfeatures being pointed out in the claims at the end of the specification. In the drawing: Fig. 1 is a perspective view of a form of con 40 tainer made in accordance with a preferred em bodiment of the inventiom' ' f > Fig. 2 is a fragmentary detail view, partly in section, taken along the line 2-2 of Fig. l; Fig. 3 is a fragmentary perspective view of 45 one corner of the container showing the inter locking parts between the cover and the side wall; ` ' Fig. 4 is a view of the blank of the body por tion of the container;l and .. Fig. 5 is a view of the closure blank. _ Similar reference numerals throughout the several views indicate the same parts. The container of the present invention, as herein disclosed, comprises a tapered body por tion or container proper and a cover portion for gage with each other to retain the body portion I in set-up condition as illustrated in Fig. 1. The walls 5 and 6 are, in the present instance, ñrst 15 folded inwardly so that they will lie inside of the assembled interlocking ñaps 3a, 4a. and 3b, 4b. Due to the construction just .described it is ap parent that the body portion of the container maybe set up and retained ln conditiony to eifec- 20 tively hold the desired material. ‘Other conven tional means may, if desired, be employed to re tain the walls in container-forming position. The cover for the container preferably com prises a ‘closure panel ‘l having extension naps 25 8, 8 and 9, 9 thereon, all defined from the closure panel by the score lines indicated. By folding these extension ñaps upwardly it is to be observed that a recessed closure is formed that will flt within the top of the body portion with the upper 30 edges of the extension iiaps lying substantially flush with the upper edges of the side walls. The extension flaps are preferably flared outwardly so that when they are bent upwardly, the sides of the cover will substantially conform to the 35 taper of the side walls. ' > A `Means are provided adjacent the corners of the body member and cover for locking the cover to the body member. For this purpose recesses lo, lo îare formed in the edges of the side waus 40 5 and 6, and tabs Il, IIL are formed on the ends of extension Vflaps ll,y 8, the position of the tabs I I, I I being such as to cause them to engage with in the recesses I0. I0 when the cover is properly positioned on the body member. The tabs II, II and recesses Il), l0, are preferably formed of similar shape so that the tabs will substantially fit within the respective recesses. The upper edges of the tabs as well as -the upper part of 50 the recesses are formed so >that the upper por tions thereof immediately adjacent the corner of the container extend at approximately .a right angular relation to the corner of the container. The upper part of the recesses will, accordingly, 55 2 2,111,888 provide an abutment serving to more or less posi tively retain the tabs II, Il. _ scription to indicate the scope of the invention. I claim: 1. A container comprising a bottom and four that a substantial portion of the ends will lie ‘ side walls, two oppositely disposed walls being of 'I‘he tabs II, I I are preferably of such length against the inner surfaces of the interengaged flaps 3a, 3b and la, 4b and be deilected thereby _to a position substantially at right angles to the extension ñaps 8, 8, so that the edges of the tabs will abut -the edges of the recesses. In other 10 words, the ends of the tabs will lie substantially in the plane of the respective walls 5 and B. Due to the presence of extension ñaps 9,V 9 restingI against the walls 5 and 6 these iiaps will serve to retain tabs II, II from any possible inward 15 movement; and, due to the presence of the inter engaged flaps 3a, 3b and la, 4b, the tabs I I will be prevented from any possible outward move ment. Thus the tabs will be eiïectively retained within the recesses. 20 ' Small openings I2, I2 may, if desired, be formed in the ilap extensions 9, 9 for the recep tion of the extremities of a spoon or similar utensil such as illustrated in my copending ap plication, Serial No. 36,759, ñled August 19, 1935. In the use of the container of the present in vention the body portion and cover will be shipped ila-t to the packer who desires to utilize the containers in the packaging of his products. It is only necessary for the packer to set up the 30 container by bringing the Walls 5 and 6 to upright 25 position and then interlocking the ilaps 3a, la, 3b, and 4b. The body portion- of the container is now ready to receive the edible material or other product which is to be packed therein. The 35 extension flaps on the cover will then be moved _to upright position and the cover pushed down into the body portion until the locking tabs I I, Ilsengage within the respective recesses I0, I0. From the foregoing description it is apparent 40 that a convenient and effective form of container for edible materials is provided which can be packed ilatvfor shipment to the user and by him readily set up and assembled without requiring special equipment. Due to the position of the. 45 locking elements and their shape the cover is se curely retained upon the body portion and the likelihood of its becoming accidentally displaced is minimized. At the same time the cover of the container may be readily removed by grasping 50 and lifting one of the flap extensions of the cover whereupon the locking tabs will become dis placed from the recesses I0, I0 permitting the container to be readily opened for access to the contents. 55 . While the present description sets forth a pre ierred embodiment of ~the invention, numerous changes may be made in the construction without departing from the spirit of the invention, and it is therefore desired that the present embodi 60 ment be considered in all respects as illustrative and not restrictive, reference being had to the appended claims rather than to the foregoing de at least double thickness and comprising inner> and outer panels, a recessed cover portion for the container comprising a closure panel having upwardly foldable extension iiaps thereon adapt ed to lie fiat against the side walls of the con tainer when assembled therewith, the inner panel .10 of the double thickness side walls having inward ly directed recesses formed at each upper edge .thereof adjacent the corners ofthe container, and tabs on each end of two oppositely disposed extension iiaps on the cover adapted to be re ceived snugly within said recesses and lie against the outer panel of said double thickness side wall in substantially the plane of said inner panel to ‘ retain the cover in place. 2. A container comprising a bottom and four 20 side walls, interlocking iiaps on the ends of two oppositely disposed side walls, said interlocking flaps being adapted to lie outside of and retain the other two oppositely disposed side walls in up right position whereby two oppositely disposed side walls of at least double thickness are provided comprising inner and outer panels, av recessed cover portion for the container comprising a clo sure panel having upwardly folded extension flaps thereon adapted to lie'fiat against the side walls o! the container when assembled therewith, the in ner panel of the double thickness side walls having inwardly directed recesses formed on each edge thereof adjacent the corners of the container, and tabs on each end of two oppositely disposed extension flaps on the cover adapted to be re ceived within said recesses to retain the cover in place, said tabs being of such length as to beary against the outer panel of the double thickness side walls and be deflected thereby so that a por 40 tion 'of the tabs will lie nat against the outer side wall panel and substantially _in the plane of the inner side wall panel whereby the edge of the material comprising the tab will bear against the edges of the inner panel at the recesses therein. 3. A container having a bottom wall, four side walls, two oppositely disposed side walls being of double thickness, a closure panel having upward ly extending flaps along at least two opposed sides, the inner wall panels of the double thick ness side walls being formed with recesses ex tending inwardly from the vertical corners of the container, laterally extending tabs on each end of the upwardly extending ñaps on the closure -panel, said tabs being adapted to ñt ñatwise into said recesses to lie substantially flat against the outer panels of said double thickness side walls and contacting edgewise against the re cessed edges of the inner wall panels, whereby 60 said closure is held in place within the container.
