' sum 2 BF 2 t INVENTOR ARTHUR J. WEISS AT ORNIZYS MOLDED PULP EGG CARTON An object of this invention is to provide a novel carton having a body defined by a bottom wall, a pair of sidewalls and a pair of end walls, a pair of covers for opening and closing an end of the carton body opposite the bottom wall, each of the covers including a top panel, a pair of side panels and a pair of end panels, and a connecting panel between the adjacent ones of the side and end panels for facilitating the introduction of a person's finger between the pair of covers and the subsequent opening thereof whereby access to the interior of the carton body and articles therein is effected rapidly and efficiently.

A further object of this invention is to provide a novel carton of the type just described in which the carton body is divided into a plurality of pairs of generally cup-shaped article receiving compartments with a compartment of each pair of compartments being disposed on opposite sides of a longitudinal centerline of the body, the compartments each having end body wall portions terminating in respective bottom walls, the end body wall portions of at least one of the pair of compartments being unconnected and spaced from one another by a gap across the longitudinal centerline of the carton, and at least another of the pair of compartments being connected to each other across the longitudinal centerline whereby transverse buckling of the carton body is precluded.

With the above and other objects in view that will hereinafter appear, the nature of the invention will be more clearly understood by reference to the following detailed description, the appended claims and the several views illustrated in the accompanying drawings:

IN THE DRAWINGS FIG. 1 is a top perspective view of a novel carton constructed in accordance with this invention, and illustrates a pair of covers closing an upper end portion of a body of the carton.

FIG. 2 is a fragmentary bottom perspective view of the carton of FIG. 1, and illustrates a plurality of pairs of cup-shaped article receiving compartments of the carton body, and a connecting wall portion between the lower end portions of two of the compartments.

FIG. 3 is a top perspective view of the carton of FIGS. 1 and 2, and illustrates one of the covers in an open position thereof and means forming an integral portion of the open cover for facilitating the opening thereof.

FIG. 4 is an enlarged sectional view taken generally along line 4-4 of FIG. 1, and illustrates the cross-sectional configuration of the carton along a longitudinal centerline thereof.

FIG. 5 is a sectional view taken generally along line 5-5 of FIG. 4, and illustrates a wall portion connecting two adjacent compartments across the longitudinal centerline of the carton body.

FIG. 6 is a fragmentary sectional view taken generally along line 6-6 of FIG. 4, and illustratesinternally recessed connecting walls between side and end walls of each of the covers which define the means for facilitating the opening of the covers.

FIG. 7 is a sectional view taken generally along line 7-7 of FIG. 4, and more clearly illustrates the connecting panels between adjacent side and end panels of the covers.

A novel carton constructed in accordance with this invention is generally referred to by the reference numeral 10, and is an integral one-piece structure of a molded pulp construction. The carton 10 comprises a carton body generally referred to by the reference numeral 12 and a pair of

covers

13, 14.

The carton body 12 includes

opposite end walls

15, 16, a pair of sidewalls 17, 18 and a bottom wall, generally referred to by the reference numeral 20 (FIG. 2) which is defined by a plurality of individual bottom wall portions or walls 21. The carton body 12 is divided into a plurality of pairs of compartments 22 by a longitudinal partition wall 23 (FIG. 4) and a plurality of transverse partition walls 24 (FIGS. 2 and 3). One

compartment 25 of the plurality of pairs of compartments 22 is disposed to one side of the longitudinal center partition wall 23 while another compartment 26 of each of the pairs of compartments 22 is positioned at an opposite side of the longitudinal centerline of the carton body.

Each of the

compartments

25, 26 includes a compartment body (unnumbered) having a lower end body wall portion 27 terminating at an adjacent one of the bottom wall portions 21. The body wall portions 27 of all but the second pair of compartments from each end of the carton body 12 are free and unconnected and are spaced from one another by a gap 30 across the longitudinal centerline of the carton body 12, as is best illustrated in FIGS. 2 and 6 of the drawings.

The second pair of compartments 26 from each of the opposite longitudinal end portions of the carton body 12 are connected to each other across the longitudinal centerline of the carton body by identical connecting wall portions, generally referred to by the reference numeral 31. The connecting wall portions 31 each include a bottom connecting wall portion 32 FIGS. 4 and 5) coplanar with the bottom walls 21 of the

adjacent compartments

25, 26 and upwardly diverging connecting wall portions 33, 34 (FIG. 4). The connecting wall portions 31 reinforce the carton body 12 in a transverse direction and prevent the carton body from collapsing under the influence of forces applied against the sidewalls 17, 18.

Means in the form of three identical upwardly directed

bosses

35, 36 and 37 function to retain the

covers

13, 14 in the closed positions thereof, as is best illustrated in FIG. 5 of the drawings. The bosses 35 through 37 each include an identical slot 38 which cooperates with the covers l3, 14 in a manner to be described more fully hereafter.

The

covers

13, 14 are generally identical and each includes a top panel 39, opposed

side panels

40, 41, and

end panels

42, 43. The side panel 40 of the cover 14 is joined to the sidewall 17 of the carton body 12 along a fold line or hinge line 44 while the side panel 40 is joined to the sidewall 18 along a similar fold or hinge line 45. In the closed position of the covers 13, 14 (FIG. 5) the

side panels

41, 41 of the covers are in opposed abutting relationship and are received in the slots 38 of the bosses 35 through 37. The slots 38 of the bosses 35 through 37 thereby function to retain the

covers

13, 14 in the closed position thereof. Articles A such as eggs or similar articles individually packaged in each of the

compartments

25, 26 are removed therefrom by opening the

covers

13, 14 by hinging the same about the

respective fold lines

45, 44.

Means 50 are associated with each of the covers l3, 14 to facilitate the opening of the covers to gain access to the interior of the carton body 12. The means 50 is an identical connecting wall 51 at opposite longitudinal end portions of the

covers

13, 14 between the

side panels

41, 41 and

adjacent end panels

42, 43. The connecting walls or panels 51 are generally of a triangular configuration set oh by

fold lines

52, 53 which converge toward the top panel 39. Each of the connecting panels 51 opens concavely outwardly and adjacent pairs of the connecting panels 51 define a finger-receiving recess, generally referred to by the reference numeral 55 (FIG. 7).

The

covers

13, 14 are opened by a person inserting one or more fingers or thumbs into the recess 55 against either or both of the connecting panels 51 at either of the opposite longitudinal end portions of the carton 10. Preferably a persons thumbs are inserted into one of the recesses 55 in the manner illustrated in phantom outline in FIG. 1 of the drawings while the carton 10 is supported in the palm and fingers of the person. By pressing against the connecting panels 51 and turning one's thumbs away from each other in the direction of the unnumbered headed arrows in FIG. 1 the

covers

13, 14 are readily and effectively progressively opened by folding about the

hinge lines

44, 45.

From the foregoing, it will be seen that novel and ad vantageous provisions have been made for carrying out the desired end. However, attention is again directed to the fact that additional variations may be made in this invention without departing from the spirit and scope thereof as defined in'the appended claims.
