1 An object of this invention is to provide acardboard container for ice cream, or the like, which can be readily opened by unfolding the container from about the enclosed ice cream so as to per- 5 mit the mass of ice cream to be removed and transferred to a dish as a block.
Another object is to provide a container which will permit this unfolding to be accomplished with a minimum of movements on the part of an operator.
These and other objects, as will hereinafter appear, are accomplished by this invention which is fully described in the following specification and shown in'the accompanying drawings, in 16 which- Figure 1 is a perspective view of an assembled carton embodying the invention;
Figs. 2, 3 and 4 are perspective views of the carton in various stages of being opened;
Fig. 5 is a plan view of the blank from which the carton is folded;
Fig. 6 is a slightly enlarged section on the line 6 of Fig. 1; and
Fig. 7 is a section on the line 7-7 of Fig. 6.
The embodiment illustrated comprises a carton formed from a blank, as shown in Fig. 5, having a bottom 10 opposing sides 11 and 12 formed integral with the bottom but separated therefrom by fold lines. The bottom also has bottom fiaps 80 13, 14, while the side 11 has inner flaps 15, 16
separated therefrom by fold lines, and the side 12 has outer side flaps 1'7, 18 also separated therefrom by fold lines, the flaps 13 and 14 being severed from the flaps 17 and 18 on the lines 19. The side 11 has a cover flap and the side 12 has an overly ing flap 21 also separated by fold lines. The outer side'fiaps 17, 18 have locking flaps 22, 23 which are adapted to overlie and to form an interlock for holding the carton in assembled relation.
To fold the blank up so as to form a carton, the bottom flaps 13, 14 are folded up substantially at right angles to the bottom. The inner flaps 15, 16' are then folded up in the same way and the side 11 folded up until it assumes a position little less than 90 from that of the bottom. The flaps 13, 15 and the flaps 14, 16 are so formed that their adjacent edges meet throughout, as shown in Fig. 6. This is a point of considerable importance for the reason that substantially no space is left between them through which melte ice cream or-other liquid can seep. Continuing the assembling operation, the outer side flaps 1'7, 18 are bent up and the side 12 is then bent up, causing the outer side flaps to overlie the inner side flaps and the bottom flaps. The side flaps are then secured in this position by adhesive, as will presently be described, and the carton is then ready for filling. After filling with ice cream, or the like, the cover flap 20 5 is folded down so as to close the top of the container after which the overlying fiap 21 is folded over it and the locking flaps 22, 23 folded over the flaps 20, 21 and locked by inserting the locking tongue 24 in a locking slot 25 in a well known 10 manner.
The overlying side flaps are secured together preferably by means of a relatively narrow strip 26 of a suitable adhesive, such as glue, which is applied to the contacting surfaces of all the flaps 14, 16, 18, and these surfaces are then pressed together and are held in this position until the adhesive has set. The flaps 13, 14, 15,
16 are provided with score lines 13 14 15 16 respectively on the surfaces that have been 20 glued and adjacent the glue strip to assist in opening up the carton, as will later be described.
In opening up this carton it is preferably laid fiat with the side 12 down. With the bottom of the carton toward the operator he then grasps 25 the carton in his two hands with his left thumb on the corner A (Fig. 2) and his rightthumb on-the comer B. By forcing these corners outwardly, as shown in Fig. 3, he pulls the outside flaps away from the inside flaps and in doing 30 so the'strips of glue 26 draw the inside flaps 15,
16 outwardly, pulling them out of contact with the ice cream or other material within the carton.
This operation of drawing the inside flaps outwardly is assisted by the score lines 13*, 14 15 and 16 which yield, as shown in Fig. 3. When the outer side flaps have been laid back, as shown in Fig. 4, the operator then takes hold of the cover flap 20 and the side flaps 15, 16; which have already been opened outwardly to some extent, and the side,11, and the flaps carried thereby can then be folded back and spread out on the table substantially as shown in the position of Fig. 5, at which time the block of ice cream C rests on the opened carton but is only in contact with the side 12. A knife or other suitable flat utensil can then he slid under the block of icev cream so that itcan be lifted free from the cartonand deposited on a plate. I 50 Thus it will-be seen that the locking flaps, made integral with the outer side flaps, serve' the additional purpose of tabs for pulling open the carton.
While I have shown and described but a single embodiment of my invention, it is to be understood that it is capable of many modifications. Changes, therefore; in the construction and arrangement may be made which do not depart from the spirit and scope of the invention as disclosed in the appended claims.
I claim:
1. A folded cardboard carton comprising a bottom and opposite side members, the bottom having bottom flaps and the side members having side flaps, the side flaps overlapping in folded relation, each outer side flap overlapping the opposing side flap and bottom flap, the last named flaps lying in thesame plane adjacent the outside flap, and a narrow strip of adhesive connecting the overlapping surfaces of the side and bottom flaps and extending longitudinally of the outer flap and spaced from the outer edge of the outer flap'so as to leave a longitudinally extending unattached outer edge portion on the outer flap.
2. A folded cardboard carton comprising a bottom and opposite side members, the bottom hav-' ing bottom flaps and the side members having side flaps, the side flaps overlapping in folded relation, each outer side flap overlapping the opposing side flap and bottom flap, the last named flaps lying in the same plane adjacent the outside flap and having their meeting edges normally contacting through substantially their entire length, and a, narrow strip of adhesive connecting the overlapping surfaces of the side and bottom flaps and extending longitudinally of the outer flap and spaced from the outer edge of the outer flap so as to leave a longitudinally extending unattached outer edge portion on the outer flap.
3. A folded cardboard carton comprising a bottom and opposite side members, the bottom having bottom flaps and the side members having side flaps, the side flaps overlapping in folded relation, each outer side flap overlapping the opposing side flap, and a narrow strip of adhesive connecting the overlapping surfaces of the flaps and extending longitudinally of the outer flap and lying within the outer flap so as to leave a longitudinally extending unattached outer edge on the outer flap, the inner side flap being scored along a line near the adhesive strip so that a pull on the outer flap will bend the inner flap along the score line.
4. A folded cardboard carton comprising a bottom and opposite side members, the bottom having bottom flaps and the side members having side flaps, the side flaps overlapping in folded relation, each outer side flap overlapping the opposing side flap-and bottom flap, and a narrow strip of adhesive connecting the overlapping surfaces of the flaps and extending longitudinally of the outer flap and lying within the outer flap so as to leave a longitudinally extending unattached outer edge on the outer flap, the inner side flap being scored along a line near the adhesive strip so that a pull on the outer flap will bend the inner fiap along the score line.
5. A folded cardboard carton comprising a bottom and opposite side members, the bottom having bottom flaps and the side members having side flaps, the side flaps overlapping in folded relation, each outer side flap overlapping the opposing side flap, a narrow strip of adhesive connecting the overlapping surfaces of the flaps and extending longitudinally of the outer flap and lying within the outer flap so as to leave a longitudinally extending unattached outer edge on the outer fiap, and locking flaps hingedly connected to the tops of the outer side flaps and serving also as tabs adapted to be grasped to pull the outer side flaps away from the inner side flaps to open the carton.
