8 Claims.

This invention relates to cartons, and more particularly to a divisible carton capable of being formed from a single sheet blank.

A divisible carton is an especially practical container for canned and bottled goods intended to be sold from retail outlets. customers of such stores frequently desire to purphase only a half case or half carton of such goods, confronting the dealer with the necessity of repackaging the purchase. If, for example, a full case of canned goods contains twenty-four (24) cans, and the customer wishes to purchase a half case, the dealer must find or improvise some container which will enable the customer to carry twelve (12) cans without undue inconvenience. The ordinary paper bag is obviously unsuitable for this purpose, and it is, therefore, usually necessary to spend a considerable amount of time looking for an empty box or emptying a partially full carton. Even after a makeshift container has been provided for the customer, the dealer still finds himself in possession of a full-case carton occupying the same amount of space normally allotted to twenty-four (24) cans but containing only twelve (12).

These disadvantage are immediately overcome by the use of a divisible carton for packaging canned and bottled goods, since it is only necessary to divide the carton along scored lines to provide the purchaser with a half case lot already enclosed in a convenient container.

While divisible cartons of various kinds are well known in the container art, the patent to Grecco, No. 2,359,986 being an example, none of the present types of divisible cartons is completely satisiactory. For example, it is usually necessary to cut through four walls of the car-' ton in order to divide it, so that considerable time and effort is required to effect the division. This is particularly inconvenient when the carton is bulky or heavily loaded, since the full size carton must be laid on its side or completely turned over in order to complete the dividing cut.

By contrast, it is an object of this invention to provide a carton of the character described which may be readily separated into two complete containers of smaller size by merely making a single cut through each of a pair of opposite end walls thereof.

Another object of this invention resides in the provision of a divisible carton which may be fo'med from a single sheet blank and which will have a pair of adjacent partitions through its center along the line of division.

Another object of this invention resides in the provision of a carton of the character described which may be readily divided with a knife and which will' provide a pair of smaller containers each complete in itself and requiring nofurther Construction or assembly and no additional ma-- terials.

, Another object of this invention resides in the provision of a carton of the character described which may be readily divided to provide two complete half-carton container each having at its top a pair of flap members which need only be folded outwardly to provide' a pair of handles whereby the container may be conveniently carried.

Still another object of this invention` resides in the provision of a divisible carton of the character* described in' which the handles on the halfcarton containers will be parallel to' the longer dimension of the* containers* to enable the same tobe carried with greater convenience.

With the above and other objects in View which will appear as the description proceeds, this in vention resides' in the' novel combination and arrangement of' parts' substantially as hereinafter described and more' particularly dened by the` appended claims, it being' understand that such changes in the precise embodiment of thehereindisclosed invention may be made as come' within' the scope of the claims.

The accompanying' drawings illustrate one` complete example of a physical embodiment; of the invention constructed in acc'ordance with the best modes so far devised for' the practical application of the principles thereof, and in which:

Figure I is a perspective View of the` complete carton of' this invention in' closed position;

Figura 2 is a plan view of a single sheet blank cut andscored` so that it may be folded toform the` carton of this invention;

Figure 3 is a perspective view showing the carton partially folded and assembled;

Figure 4 is a perspective View of the carton partially cut, showing its two component half carton containers; and

Figure 5 is a perspectiveview of one of the half carton containers formed by dividing the carton of this invention.

Referring now more particularly to the accompanying drawings in which like numer-als designated like parts throughout the several views, the numeral to designates generally the completely assembled undivided carton` of this invention. Although thecarton may, of course be fabricatedfrom a number of separate sheets or blanks, and may be constructed of any suitable material, the advantages of this invention are best realized when the carton is made from a single sheet blank 9, preferably cut or stamped from corrugated kraft board.

A strip ll, defined by slits and scores in the blank 9, extends medially through the entire length of the blank. This strip, When folded, forms the single thickness side walls l2 and end walls I 3 of the completed carton o, and its width is therefore equal to the height of the completed carton. Lateral scores [4 across the strip divide it into side wall forming panels l2' and end wall forming panels l3' and facilitate bending to form the corners |5 at the junctu'es of the side and end walls of the assembled carton. A short tab IG, projects from one end of the strip ll and is adapted to be Secured to the other end l' of the strip, thus in effect providing the carton With a continuous wall about its perimeter.

A pair of fiaps !8 and I 8' extend from each side of each of the two end wall forming panels l3' of the strip ll. These fiaps l8 and I8' preferably extend laterally from the strip Il a distance substantially equal to half the length of the carton, although they may be made shorter if desired. The width of each pair of fiaps !8 and l8', measured along the strip ll, is equal to the width of the complete carton IO. The inner edge of each of the fiaps is defined by a score 19 which concurrently defines an edge of the end wall forming panel l3' from which the fiaps project. The score IQ enables the fiaps !8 and |8' to be bent inwardly at right angles to the end walls of the carton I 3 (see Figure 3) so that these fiaps may form the inner course or layer of a double thickness top Wall 'I and bottom wall 8 of the carton.

The two fiaps a and l8' of each pair are spaced apart a small distance, forming between them a slot 20 extending outwardly from the edge of the strip I l, at right angles thereto. The width of this slot is preferably equal to about four times the thickness of the material of which the blank is formed.

A larger fiap 2I extends from each side of each of the two side wall forming panels I2' of the strip II. The inner edge of each fiap 2! is defined by a score 22 which concurrently defines an edge of the side wall panel I2' from which the fiap projects. The width of each of the fiaps 2l measured along the strip II is equal to the length of the carton.

Each of the fiaps 2l has an intermediate score 23 parallel to the score 22 and at a distance outwardly therefrom substantially equal to half the width of the carton. The scores 2 2 and 23 of each fiap 2l define between them the panels 24 and 24'. When the carton is assembled these panels are bent inwardly along the score 22, at right angles to the side wall panels l2', so that panels 24 will overlie fiaps l8 and panels 24' will" overlie fiaps l8' to form the outer layer or course of the double thickness top wall 'l and bottom wall 8 of the carton.

The portion 25 of each fiap 2! which is outward of the score 23 is bent along the score 23 to be perpendicular to the outer cover forming panels 24 and 24', and when the panels 24 and 24' are bent into position the portions 25 of each fiap 2l pass inward through the spaces or slots 20 between the inner layer cover fiaps [8 and aa' so that the four surfaces of the fiap portions 25 are adjacent to one another along the center line 26 of the carton, where they form a pair of adjacent vertical dividing partitions 21. The slots 20 must thus be equal in Width to four times the thickness of the material from which the blank is fabricated, so that they will accommodate the four superimposed fiap portions 25 which form the partitons 21.

A slot 29, parallel to the strip ll and of a size and shape to Conveniently accommodate the hand, is cut in the outermost portion 25 of each of the fiaps 2 I, and the outer edge of each fiap 21 is provided with the general contour of a handle. A third or outermost score 30 on each of the fiaps 2l is parallel to the outer two scores thereon (22 and 23) and defines the inner edge of the outermost portion 28 of the fiap. When the carton is severed by making a vertical cut through each of the end walls [3 thereof along a line 3! connecting the slits 20 and between the two partitions, the outward portions 25 of the fiaps 2l form the tops of the two resulting halfcarton containers and the handle shaped outermost portions 28 on these flaps may be bent outwardly along the score 30 to provide a pair of handles whereby each carton may be Conveniently carried.

In assembling the carton, right angle bends are first made along each of the scores |4 across the strip l l. The tab [6 is then in a position adjacent to the opposite end ll of the strip Il, to which it may be Secured in any suitable manner as, for example, by means of glue or staples. At this point the partially assembled carton Will have the appearance of a rectangular tube With fiaps 18, a' and 2l extending from each end thereof. Each of the fiaps l8 and I8' is next bent inwardly along the score IS at right angles to the end wall [3 from which it extends. The fiaps l8 and !8' thus form the inner course or layer of the double thickness top wall 'I and bottom Wall 8.

The outer portions 25 of the fiaps 2| are bent inwardly at right angles to the inner panels 24 and 24' along the scores 23. Each entire fiap 2l is then bent inwardly along the score 22 and the outer portion 25 thereof is passed through the slits 25 between the fiaps |8 and l8' to permit the cover panels 24 and 24' to be folded perpendicular to the side wall 12. The cover panels 24 will thus overlie the fiaps I8 at the top and bottom of the carton.

The inner surfaces of the panels 24 and 24' are preferably secured to the outer suraces of fiaps I 8 and l8', respectively, by means of glue or staples. However, if it is desired to leave the carton in a condition such that the top thereo may be readily opened, only the fiaps which form the two layers of the bottom wall 8 of the carton need be so Secured to one another. It will then require a slight effort to dislodge the outer portions 25 of the fiaps 2I, which form the outer layer of the top Wall T, so that the contents of the carton will be reasonably secure against spilling, although the top may be opened when desired by simply unfolding the panels 24 and 24' along the scores 22, drawing upward the outer portions 25 of the fiaps 2! in so doing. If desired, gummed tape may be put along the corner formed by the marginal edges of the end walls 13' and the panels 24 and 24', thus scaling the top of the carton in place but permitting it to be readily opened.

It will thus be seen that the complete carton has single thickness side walls l2 and end walls !3 and a double thickness top wall 'l and bottom wall 8, while each of the adjacent central parti-. tions 27 formed by the cooperating outward portions 25 of the fiaps Zi is two layers thick.

It will be understood that this inventio n also lends itself tothe construction of a divisible carton in which each of the partitions is only one layer th'ck. This may be accomplished by making the outward portion 25 of one flap 2! extending from each of the side wall panels !2' slightly longer than the height of the carton, and forming this flap with a straight, rather than a handle-shaped outer edge. The fiap 2! extending from the other marginal edge of the side wall would not have an outer portion 25. The outermost portion of the longer flap would then be bent outwardly, at right angles to the partition forming portion thereof, to be Secured along the under surface of the flaps [8 or 18' which are adjacent to the side wall from which it extends. It will, of course, be understood that the individual containers resulting from the division of such a carton will not be provided with handles.

To divide the carton of this invention it is necessary only to make a single vertical cut through each of the end walls !3 along the line 3l which joins the two slots 23. This may be very conveniently accomplished by inserting a knife blade between the two adjacent central partitions 21 and slicing outwardly and downwardly. Preferably a dotted line or some similar devce is printed or embessed on the end walls of the carton to indicate the lines 3! along which the dividing cuts are to be made.

It will be readily seen that severing the carton along the lines ill will provide two complete containers each having half the capacity of the undivided carton. The top 32 of each of these containers is formed from the outer portion 25 of the fiaps ZI, which formed one of the two adjacent partitions in the undivided carton. The side walls !2 of the undivided carton form the bottoms of the half carton containers, while half of the top wall 1 and the corresponding half of the bottom wall 5 of the undivided carton become the side walls of each half carton container.

When the carton has been divided, the handleshaped outermost portions 28 of the flaps 2! may be bent outwardly along the scores 30 to provide a pair of handles whereby each half-carton container may be Conveniently carried.

, If it is desired to make the carton of this invention divisible into two containers of unequal size, this may be readily accomplished by making one of the inner layer flaps i& of each pair wider than the other fiap iii', and by making the outer cover panels 2&- which extend from one of the side walls [2 p-roportionately wider than the panels 24' extending from the other side wall. It is thus entirely practicable to produce, for example, a carton having a Capacity of twelve cans which could be divided into two smaller containers, one having a capacity of eight cans and the other four cans. To accomplsh this, flaps !8' would be made twice as wide as fiaps IS and panels 24' would likewise be made twice as wide as panels 24. A carton so designed would, of course, be assembled in the same manner as a carton divisible into two equal containers and the partitions in such a carton would be located to one side thereof one-third of the width of the carton from one of the side walls, rather than along the center line of the carton.

From the foregoing description taken in connection with the accompanying drawings, it will be readily apparent that this invention provides 6. a divisible carton formed from a single sheet blank which may be divided by merely making a single vertical cut through each of the end walls' of the carton thus providing two smaller containers which will have handles parallel to their longer dimension whereby they may be conveniently carried.
