Various prior art carton boxes have been provided wherein handles have been formed from their upper flap, but to acquire any clearance for the grasping of the handle as when the product laden carton is to be carried, such handles usually are designed having their side edges extending downwardly and partially formed of the side walls of the carton. Usually this type ofa designed carton handle will suffice where the product being carried has been prepackaged in additional containers that are packed in said carton, such as, for example, six packs of a beverage, or other product, and wherein any openings caused in the side walls of the carton due to this handle edge extensions are insufficient to allow any spillage. But, where-bulk material,-

upward parts of said walls, usually provides a sufficientopening that will allow for spillage of the bulk material therefrom. Hence, the type'of receptacles such as disclosed in the US. Pat. Nos. 2,723,027 and 2,986,324, are believed to be deficient for use in holding any'such bulk material for the reason previously analyzed.

For the foregoing reasons, the principle object of this invention is to provide a carton having a handle means formed entirely from its upper end closureand yet provides a means for furnishing sufficient clearance for insertion of the hand as when the carton is being carried.

A further object of this invention is to provide a design for formation of a handle entirely from 'the upper flaps of a carton and which flaps are cooperative in providing sufficient clearance to facilatate grasping of the carton handle.

Another object of this invention is to provide a carton having weakened areas proximate its upper portion which areas can be conveniently manipulated to provide clearance for grasping of an integrally designed handle, but yet not significantly weaken the carton structurally.

Another object of this invention is to provide a convenience handle for a carton which can be formed in the carton blank as it is being cut and processed in a machining operation. I

Other objects will become more apparent to those skilled in the art upon reviewing the contents of the summary of the invention, and the description of its preferred embodiment in view of the drawings. BRIEF DESCRIPTION OF THE DRAWINGS In the drawings,

FIG. 1 presents a perspective view of a carton showing the handle means of the invention provided in its upward portion;

FIG. 2 shows the same carton of FIG. 1 with its end closure flaps being opened to expose their undersides;

FIG. 3 depicts a view of theupper portion of the carton as the hand is being inserted to grasp the handle means of this invention;'

FIG. 4 provides a sectional view of the upward portion of the carton taken along the line 4-4 of FIG. 3; and

FIG. 5 provides an underside view of the top flap of the upper end closure showing a modification in the handle means of this invention.

DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now to the drawings, and in particular to FIGS. 1 and 2, the basic concept of the invention can becomprehended by observing that the usual form of carton or container 1, regardless whether. it be of the type for holding multiple items or bulk material, is provided with a handle means 2 formed in its upward porseries of overlapping flaps, as at 9 through 12, but more specifically, overlying flaps l1 and 12, are each articularly joined with one of the aforesaid walls of the car- The overlying flaps 12 is shown provided with a pair of cutout portions, as at 13 and 14, which have been disposed in such a manner so as to provide a length of said flap, or the strip 15, intermediate said cut outs and which is disposed to provide a handle that may be conveniently grasped by the hand of the party desiring to convey the carton.

When cartons of the foregoing design are formed from a blank, and then either manually folded, or folded through a machine operation, there is a tendency for the various overlapping or overlying flaps 9 through 12 to become 'so snugly continuous that it would be very difficult for one to conveniently grasp the handle 15 provided in the upper flap 12. Hence, a series of score lines are conveniently formed in and arranged around this upper portion of the container, and which -score lines cooperate to provide a series of mildly weakened areas in the carton walls and flaps so that as any pressure is exerted by the hand by one desiring to convey .the carton, sufficient clearance will be provided surrounding the location of the handle 15 so the fingers may be easily slid under said handle to provide for its grasping and to facilitate the carrying of the bulk ladened carton.

As shown in FIG. 3, usually the index finger and thumb are customerily used in grasping a handle of this nature, and they insert into the two cutout portions, or

hand holes, as'shown, and are closed against the edges of the handle length 15. But, as previously described,

the disposition of score lines at locations that can be in- 3 disposed approximately centrally of said flap and extending from its leading edge at a location where the flap joins with the wall 4. in addition, another score line 17 is provided across the overlying flap l2, approximately centrally thereof, and from one side edge to the other, so that as the hand grasps the handle 15, said handle will bend slightly upward, at the location where this score line crosses the same. To provide for this cooperative bending of the flaps and handle, preferably at least a portion of the overlying flap 12, except along its handle 15, will also be adhered, as by an adhesive or the like, to the underlying flap 11. Then, as the hand presses down as at the cut out portions 13 and 14, both of these flaps will bend downwardly while the handle 15 bends upwardly, thereby providing this clearance for its grasping by the hand. It is the location of the two aforesaid score lines 16 and 17 which, as the hand is being pressed against the flaps and inserted as shown in FIG. 3, causes the handle 15 to bend slightly upwardly, as aforesaid, while at the same time the fingers will slightly depress and bend the overlying and underlying flaps 11 and 12 downwardly along the location of said scorelines to further add to the clearance needed for insertion of the hand. To further increase the slight bulging of this carton, there are provided an additional pair of score lines 18 and 19 formed just proximate the upper edges of the walls of the carton, and in this particular instance, these score lines are slightly arcuate in design, and each is located proximate the upward edge of its respective wall where it joins with a side wall of the container, but the score line is disposed slightly below said upward edge at the center of the wall. in addition, short lengths of score lines, as at 20 and 21, are

formed approximately vertically, at a central location of the walls 3 and 4, and extend from the location where the flaps join with said walls, to a downward location where each line intersects its respective arcuate score line 18 and 19. Hence, and through the disposition of the score lines as previously described, as the hand, or more specifically its fingers, are being pressed against the flaps and inserted around the handle means, such as shown in FIG. 4, said score lines induce a slight bulging in their respective front and back walls 3 and 4, which increases the clearance around the upwardly bending handle means. It can also be seen that the flaps are slightly depressed downwardly through the arrangment of their weakened areas formed along their score lines, and as shown, as the fingers grasp the handle means 15, and are inserted betwen said means and said flap 11, said handle will also have its tendency to buckle upwardly along its score line 17 as previously described. Hence, a handle has now been provided with sufficient space to provide for firm retention of the handle means, and the carton, which might be laden with a bulky material of'some weight, allowing easy carriage.

it should be remarked that any reference to and use of the word score line at the various locations in the walls and flaps of this carton is meant to be construed rather generically, and that the score line may also comprehend the use of any form of crease line in the carton paperboard, perforatedline, scratched, etched, or indentation marks, or any other related paperboard formation, that may desirably provide a mildly weakened area in the carton at those locations where clearance is needed.

it would also be noted. that various forms of reinforcing tape, or the like, as at 22, is adhered to the various flaps and walls of the'container to provide for their reinforcement against fracture and fatigue particularly at those locations where bending is caused to provide handle mean clearance. And, it is to be further noted that the reinforcing tape is desirably provided along the under surface of the overlying flap l2 and particularly along the length of said flap that is formed into the handle means 15. This reinforcing tape may be of any variety of such tapes as are readily available upon the market, and which are usually nylon or other fiber reinforced to resist their tearing A modification in the formation of the handle means of this invention is shown in FIG. 5. This figure which provides an underside view of the overlying flap 12 of the upper end closure of the carton is provided having a hand aperature 23 cut therethrough, and, as distinct from the handle means 15 previously described, as formed from said flap, this handle means 24 comprises a length of reinforcing tape or other fabric that is adhered to the side portions of said flap, and is arranged for spanning the distance across the aperture 23. Hence, the length of tape 24 that spans this aperature provides a handle that may be grasped by the fingers when one desires to carry off the carton. As previously described in the other embodiment of this upper flap, a score line 15 is arranged centrally across the flap and can provide some bending and clearance as the hand is inserted under the tape 24. All other aspects of this modified carton are similar to the previous description of the other flaps and walls of the preferred carton.

It should be obvious that a further attribute in the formation of a carton'of this style is that the handle means can be formed during the processing of the carton as its blank is being cut and then folded into an enclosure. Other forms of handle type cartons as shown in the prior art usually incorporate some type of wire or plastic handle, or the like, that must be separately attached to the upper flaps of the carton after it has already been cut as a blank and then folded into its tubular form.

Other variations in the construction of the handled carton ofthis invention, within the scope of the appended claims, will appear, to those skilled in the art in light of the foregoing disclosureThe description of this preferred embodiment is merely meant to be illustrative of the principles of this invention, and any equivilent or similar designs in a handled carton which embraces the principle of this invention are intended to be a protected by said claims.
