CARTON Filed July 22, 1938 Patented Nov. 28, 1939 i UNITED STATES PATENT OFFICE CARTON tion of Wisconsin Application July z2, 193s, serial No. zzosi 7 Claims.

'I'his invention relates to a carton, and particularly to a carton made of fibrous material for packaging ice cream and other frozen comestibles.

The present invention contemplates a carton construction provided with means for readily opening the same so as to make the contents accessible without any attendant peeling or tearing of the fibrous material from which the carton is made.

An object of the invention is to provide a carton for ice cream and the like which when opened may be spread out flat so as to completely expose the frozen contents of the package for slicing or removal as a whole.

A further object of the invention is to provide a carton for ice cream packaging which is formed from a single blank of board scored and folded to provide a carton with interlocking ends so arranged and associated with respect to the cover that when the cover is opened the whole carton will open exposing the contents for slicing or removal as a unit.

A still further object Vof the invention is to provide a carton formed from a single blank of thin board material scored and folded in a box form and provided with a ap which is glued to close the carton -and which can be readily grasped and torn off to expose the carton for removal of its contents.

Further advantages and details vwill be apparent from the accompanying drawing in which:

Figure 1 is a .plan view of the blank from which the carton is made.

Figure 2 is a perspective view of the blank in folded and unsealed condition,

Figure 3 is a front view of the sealed carton,

Figure 4 is a sectional view taken on line 4---4J of Figure 1, and

Figure 5 is a side view of the sealed carton illustrating the grasping tab in bent position.

Referring to the drawing, the carton is made from a single blank of paper board which is preferably impregnated or coated with paraffin wax. 'I'he blank is scored along lines I, 2, 3, and 4 to provide a front wall I8, a cover I3, rear Wall I2 and bottom wall II. .f

'I'he front wall I8 is provided with free end flaps I5 and I6 separated from the adjacent llaps by slit lines 6 and 1. Flap I5 is provided with a tongue portion 24. Flap I6 is slit along lines 23 and 23'. Rear wall I2 is similarly provided with end aps I9 and 28 separated vfrom adjacent aps by

slits

26 and 28, and 25 and 21 respectively. Flap I8 is provided with slits 23 and 23', and flap 28 is provided with a tongue 24.

:The cover I3 is provided with inner end flaps 2| and 22. The bottom II is provided with inner end aps I1 and I8. One end of the carton is 5 adapted to `be closed by overlapping inner end aps I8 and 22, and interlocking thereover outer flaps I6 and 28 by inserting tongue 24 through slit 23. The other end of the carton is adapted to be closed similarly by folding inner flaps I1 10 and 2I in overlapping relation and then locking outer overlapped aps I5 and I8 by means of tongue 24 extending through slit 23'.

The cover I3 has a ap extension consisting of adjacent panels I4, 35, 36 and 31 formed by 15 score lines 30, 48 and 4I. Panel I4, designated as extension panel, is hinged to the cover along score line 4. Panel 35, designated as outer grasping panel and panel 36 as inner grasping panel, are of substantially the same width. Panel m 31 will be referred to as the glue panel.

Score lines 48 and 4I are partially cut through the blank as shown in Figure 4. Score lines 39 are provided at each end of panel 35 and inter-V secting score lines 38 are provided at the ends z5 of panel 36 as shown in Figure 1 for a purpose to be explained later.

In making the carton for use, the ap extension is folded back on itself so that panels 36 and 31 are folded over on panels I4 and 35 along 30 score line 48. The folded-over abutting faces of

grasping panels

35 and 36 are preferably glued together by adhesive 55. Glue panel '31 is then glued by adhesive 58 to the upper edge of the front wall I8 as shown in Figures 3 and 4.

The sides of panels I4, 35, 36 and 31 constituting the extension on cover I3 are preferably sloped toward each other as shown in Figure l so that the grasping panels will be spaced away slightly from the ends of the carton as shown 40 in Figure 3.

The cartons are shipped by the carton manufacturer to the carton user in knocked-down flat condition with the extension on cover I3 folded and glued to the front wall I8 as previously de- 45 scribed. v

In use the carton is folded up into its rectangular condition as shown in Figure `5. One end of the carton is closed by means of the end flaps previously described and ice cream or other comestible to be frozen therein is introduced at the other open end. After being filled this end is closed and the carton transferred to the hardening room. The front of the carton will have the appearance shown in Figure 3.

When the consumer is ready to use the contents within'the carton both ends of the carton are flrst opened by disengaging the interlocked outer flaps I6 and 20, and I5 and I9 at each end. 'I'he

grasping panels

35 and 36 are then seized by the lingers as shown in Figure and pulled back so as to tear the glued portion of panel 31 away from the front wall l0. The contents of.

the carton will then be left freely exposed resting upon the bottom Il of the carton.

The construction of the extension panels and score lines as previously described facilitates the ready grasping of the grasping panels and tearing open of the carton without peeling the fibrous stock material. Score lines 30-and 4| facilitate bending up of the grasping panels as shown in Figure 5.

Score lines

38 and 39 also provide corner grasping portions 60 which can be rst grasped and folded up thereby facilitating grasping of the grasping panels. There will be no peeling of the carton blank on the inside of the carton because the fibers cannot peel beyond the upper outer edge of the front Wall I llwhen the carton is opened as the fibers on the inner face of the sealing flap are discontinuous with the fibers of the overlapped portion of the front wall. The partially cut score line 40 also permits

panels

35 and 36 to. be folded compactly Without bulging at the fold'thereby giving a compact and neat appearance to the grasping panels.

The carton construction thus provides a carton made from a single blank of paper board having a cover provided with an integral extending sealing flap which serves to seal the carton. 'I'his flap is formed into panels I4, 35, 36 and 31 and is folded and secured to itself as previously explained so as to provide inner and outer ap portions. The inner face of the sealing flap is adhered to an overlapped portion of the adjacent wall by means of glue applied adjacent the inner edge of the sealing flap. The score lines 30 and 4I on the sealing flap provide hinged grasping portions for tearing open the sealing flap. Corner grasping portions are also provided by suitable score lines to facilitate seizing of the grasping panels.

It is to be understood that variations and modifications of the specific embodiment disclosed are intended to be included within the scope of the appended claims.
