The main objects of this invention are:

First, to provide a carton which is well adapted for the packaging of relatively heavy products and at the same time may be formed of relatively light paperboard stock 2 and is strong and form retainingly rigid when erected.

Second, to provide a carton having these advantages which may be quickly opened and reclosed in the event the contents are not fully removed.

Third, to provide a carton embodying these advantages which may be shipped in the collapsed form and readily set up to receive contents and conveniently sealed.

Fourth, to provide a carton embodying these advan- :tages which may be economically produced.

Objects relating to details and economies of the inventi'onwill appearfrom the description to follow. The

invention 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 carton embodying myinvention erected and sealed. FIG. 2 is an enlarged fragmentary vertical section on a line corresponding to line 2-2 of FIG. 1.

FIG. 3is a perspective View of the carton of FIG. 1 opened for access to contents. I

FIG. 4 is an enlarged fragmentary view corresponding to FIG. 2 illustrating the carton reclosed after it has been opened, as shown in FIG. 3.

" FIG. 5 is a plan view of the blank from which the carton' is formed.

FIG. 6 is a fragmentary perspective view of another adaptation of my invention. f FIG. 7 is a fragmentary perspective View of a modified-form or embodliment of my invention erected, fully closed or sealed.

FIG. 8 is a fragmentary perspective view of the modified form of FIG. 7 with the carton partially opened.

FIG. 9 is a fragmentary horizontal section on a line corresponding to line 99 of FIG. 7. FIG. 10 is a fragmentary vertical section on a line corresponding to line 1010 of FIG. 7.

' FIG. 11 is a plan view of the blank from which the embodiment of my invention, illustrated in FIGS. 7, 8, 9

and 10, is formed.

FIG. 12 is a collapsed view of the embodiment of my l invention shownin FIGS. 7-12 inclusive.

Cartons embodying my invention are well adapted for use in packaging food products and both embodiments of my invention illustrated are adapted for the packaging of relatively heavy food products, for example as so called ice cream novelties which are individually wrapped and packaged in multiples for retail sale. However, it should ,be understood that cartons embodying my invention are adapted for packaging various products which it is desirableto have sealed' initially but for which it is also desirable to have access for the removal of a portion of the contents and then reclosing the carton.

I have illustrated two embodiments of my invention,

tone ernbodiment being illustrated in FIGS. 1-6 inclusive and the other in FIGS. 7-12 inclusive. Both of these embodiments are highly desirable.

v The embodiment of my invention illustrated in FIGS. 16 inclusive is desirably formed of an integral blank illustrated in FIG. 5. This embodiment comprises the bottom 1, front wall 2, and rear wall 3 hingedly connected United States Patent 0 foraminations.

3,157,238 Patented Jan. 25, 1965 to the bottom 1 by the score lines 4. The end walls 5 are hingedly connected to the bottom 1 by the score lines 6. The front and

rear walls

2 and 3 are provided with end flaps 7 having tongues 8 on their outer ends engageable in the angled slits 9 in the end walls 5, the flaps 7 being disposed on the outer sides of the end walls 5 in interlocking, supporting engagement therewith.

The top wall 10 is hingedly connected to the upper edge of the rear wall 3 by the score line 11 and it is provided with afront wall member 12 hingedly connected to its front or swinging edge by the score line 13. The top 10 is also provided with outer end Wall members 14 which are hingedly connected thereto by the score lines 15. The top wall 10 has transversely spaced fracturing foraminations 16 therein and the. front wall member 12 has severing slits or foraminations 17. The top 10, in this embodiment, has slits 18 therein disposed in laterally spaced parallel relation to the tear foraminations 16 When the carton is erected, the top end members 14 are secured to the body portion end walls 5, desirably by adhesive as conventionally illustrated at 19, see FIG. 4, and the portions of the front wall 12 at the outer side of the severing foraminations 17 are adhesively secured to the front wall 2 of the body member. This arrangement provides the top with an opening and with a closure member 20 therefor hinged at 22 and having a portion 21 on its front end. The front portion 21 of the closure member constitutes a fingerpiece and is desirably provided with a score 23 spaced from its lower edge to facilitate grasping. The slits 18 prevent peeling of paperboard giving a clean opening and provide this closure member 20 with seal elements 24.

The embodiment of my invention shown in FIG. 6

illustrates an adaptation of my invention to an elongated type of carton 26, the closure member 27 for the opening being substantially the same as that described but extending longitudinally of the elongated carton. This figure is included merely to show the wide adaptation of my invention. v The embodiment of my invention illustrated in FIGS. 712 inclusive is formed of a single cut and scored blank of paperboard stock or the like, as shown in FIGS. 11 and 12 and it comprises a bottom 30,

side walls

31 and 32 hingedly connected to the bottom by the scores 33 and a top 34 dimensioned to correspond. to the bottom and hingedly connected to the upper edge of the side wall 32 by the score 35.

On its otheredge, thetop is provided with. a sealing flap 36' connected thereto at 37 and disposed-onthe inner side of the'wall 31 and secured thereto desirably by'adhesive and throughout its length. I

The side wall 31 is provided with end flaps 3S and the side wall 32 is provided with end flaps 39. The bottom is provided with

end flaps

40 and 41 while the top is provided with outer

end wall members

42 and 43 which overlap the

end flaps

40 and 41 on'the bottom and are secured thereto desirably by adhesive. 7;

The top 34 has laterally spaced foraminations 44 desirably of angular shape as is illustrated and it has a hinging score 45 at the inner end of and extending between these The end Wall 43 has downwardly converging foraminations 44 merging with the foraminations in the top or forming continuations of the foraminations 'in the top. These foraminations 44 terminateadjacent the upper ends of the laterally'spaced notches 46 which provide a finger tab 47.

The inner end flap 41 is provided with downwardly converging severing scores 48 which are desirably spaced inwardly somewhat from the severing scores 44 in the end wall 43, see FIGS. 8 and 9. The end wall 43 is secured by adhesive 49 to the inner end flap 41 including the removable portion 50 thereof between the severing sc 8 a dthere is a s s lil a ve n or 51 otfsetslightly from the juncture ofv the end wall po'rt1on 50 with the botto'nysee FIG. 11.
