12 Claims. (Cl. 229-28) This invention relates to cellular cartons primarily designed for use as egg cartons, but readily adapted for packaging other fragile articles. The main objects of this invention are,
First, to provide a cellular egg carton which when erected is very strong and rigid and one in which the eggs' are supported so that they are well protected both for shipment and handling of the carton.
Second, to provide a cellular egg carton having these advantages which may be formed from a unitary blank and readily set up in collapsed form, and may be quickly and easily erected.
Objects relating to details and economies of the invention will appear from the description to follow. The in- .vention is defined and pointed out in the claims.
A preferred embodiment of the invention is illustrated in the accompanying drawing, in which:
Fig. 1 is a front perspective view of a cellular carton embodying my invention.
Fig. 2 is a longitudinal section on a line corresponding to line 2-2 of Figs. 1 and 5, certain of the cells being in fully erected position and eggs conventionally illustrated therein.
Fig. 3'is a transverse section on a line corresponding to line 33 of Fig. 2 looking in the direction of the arrows with the cover shown in partially open position by dotted lines.
Fig. 4 is a cross sectional view on a line corresponding to line '44 of Fig. 2 looking in the direction of the arrows.
Fig. 5 is a cross sectional view on a line corresponding to line 5-5 of Fig. 2.
Fig. 6 is a fragmentary perspective view with portions of the cell walls in erected position and others in nonerected position.
Fig. 7 is a perspective View illustrating the embodiment of my invention, having the sectionally fracturable cover.
Fig. 8 is a fragmentary perspective view of the collapsed carton.
Fig. 9 is a plan view of the blank from which the carton illustrated in Figs. 1 to 8 is formed.
I have illustrated my invention in the accompanying drawing as embodied in .an egg carton. As stated it is particularly desirable for egg cartons although it may be .readily adapted for packaging of fragile articles such, for example, as lamp bulbs and the like.
The embodiment of my invention comprises a bottom .1, a front wall member 2 hingedly connected at its lower .edge to the bottom, a rear wall member 3 hingedly connected at its lower edge to the rear edge of the bottom 1, a cover 4 hingedly connected to the upper edge of the rear -wall member 3, the cover member having an upper front wall member 5 on its swinging edge. The hinging scores on the blank of these parts are conventionally illustrated Fig. 9, but as such hinging scores are common in egg cartons and numerous other cartons formed of fiberboard stock, they are not numbered and described.
weakened scores or perforations 26 I highly practical embodiment thereof.
2,955,736 Patented Oct. 11, 1960 The upper cell member 7 is hingedly connected at its front edge 8 to the upper edge of the front wall member 2 and is connected at its rear edge to a downturned supporting strip 9 which is disposed upon the inner side of and adhesively secured to the rear wall member 3. The lower cell member 10 is hingedly secured at 11. to the lower edge of this supporting strip 9 and is provided with an attaching flap 12 at its front edge which is disposed upon and adhesively secured to the inner side of the front wall member 2. These upper and lower cell members 7 and-10 are disposed in parallel relation to each other and to the bottom when the carton is erected as is illustrated. All of these parts of the carton are desirably of the same length, as is illustrated in Fig. 9.
The lower cell member 10 is provided with egg seat openings 13 which receive the lower ends of the eggs, as is illustrated. These seats have a plurality of radial slits in their edges forming deflectable seat tabs 14. The bottom cell member also has slot-like keeper openings 15 which open to the seat openings.
The upper cell member is transversely slit and scored to provide transversely aligned swingably adjustable cell wall members or strut portions 16 and 17 disposed in opposed pairs when in erected position and foldable or swingable downwardly to constitute side walls of the cells and laterally support eggs as is illustrated in Fig. 2. The outer end edges 18 and 19 of these cell wall members 16 and 17 are in lateral thrust sustaining engagement with the front and rear wall members when the cell wall mem! bers are in erected position and they prevent the lateral collapsing of the erected carton.
The wall members 16 are provided with dove-tailed tongues 20 which engage the keepers 15 of the lower cell member when the carton is in fully erected position. The lower cell member has strut portions 21 struck out therefrom to form the openings and keepers, and when erected they are swung downwardly into bottom engaging position, as best shown in Fig. 4. They are swung to bottom engaging position when the cell wall members 16 are swung downwardly to the position as is clearly shown in Fig. 2.
The cover flap or upper front wall member 5 is provided with laterally facing tongues 22 which are retainingly engageable with the upper cell member parts which project inwardly from the lower front wall member. These parts designated generally by the numeral 24 are of different shapes, but they are designated by the same numeral. Desirably the upper cell member has triangular slits 29 therein at its front edge which result in retaining the parts inerected position in the upwardly projecting tabs, facilitating the positioning of the cover memher 5.. 7
In the embodiment illustrated, the carton blank has a fractioning score 25 disposed centrally thereof so that the carton illustrated, designed to receive a dozen'eggs, may be divided into .two six egg cartons. For convenience in use without openingthe cover, the cover 4 and the extension 5 have transverse scores 26 positioned between the pairs of cells so that-the cover can be removed section by section to expose each pair of cells. This avoids the necessity of opening the cover when it is desired to remove eggs. At .the inner ends .of these preferably provide curved slits 27 which define tabs 28 which may be conveniently grasped for severing the cover sections from the rear wall member and the disengagement of the tongues 22 without any special manipulation of the tongues or the cover member 5 to disengage the tongues.
I have illustrated and described my invention in a I have not attempted to illustrate or describe other adaptations and modifications as it is believed that this disclosure will enable those skilled in the art to embody my invention as may be desired. The structure illustrated is, however,
