Two cartons releasably joined to form a dual carton

Abstract

A dual carton formed from two substantially identical single cartons adhered to one another with adhesive which remains tacky after the cartons are separated. Each carton has a top and tuck-in flap, and the flaps of the two joined cartons are overlapped to seal the dual carton. The tuck-in portion of the flap of one carton is adhered to the top portion of the flap of the other carton with similar adhesive as used to join the cartons. After the cartons are separated, the cartons may be individually sealed by reusing the adhesive on the wall of one carton and on the tuck-in portion of the flap of the other carton to adhere the tuck-in portion of the flaps of the cartons to the outside of the wall opposite the wall from which the flaps extend. The dual carton may be a cigarette carton of dimensions compatible with tax-stamping machinery and temporarily sealed in such a manner as to facilitate the opening and later resealing of the carton for tax-stamping purposes.

Description

BACKGROUND OF THE INVENTION

The present invention relates to the releasable connection of cartons to form a dual carton, and more particularly to the releasable connection of two separate cigarette cartons to form a dual carton compatible with commercially available tax-stamping machinery.

Cigarette packs (which usually contain twenty cigarettes) are generally rectangular in shape, having front and back long walls connected by two short side walls. Cigarette cartons typically contain two rows of five cigarette packs per row (each row arranged so that the front long walls of the packs are in the same plane and the back long walls are in a parallel plane spaced from the front long walls), and are generally known in the art as ten-pack cartons. Such cigarette cartons are generally filled with cigarette packs by the manufacturer, temporarily closed (e.g., by folding the top flap of the carton over the top of the carton and releasably securing the flap in the closed position), and shipped to various distributors. The distributors generally open the cartons to apply the tax stamp that may be required by the jurisdiction in which they operate to the ends of individual cigarette packs while the packs are still inside the cartons. Such procedures are commonly automated, to reduce time, cost, and labor, through the use of specially designed machines for applying tax stamps. Tax-stamping machines have been developed to open the cartons, apply the stamps, and finally seal the cartons for distribution. Such machines are generally commercially available, and are well known in the art. These machines have been developed for ten-pack cartons, i.e., cartons containing two rows of five cigarette packs per row. A typical tax-stamping machine is model FUSON manufactured by Meyercord of 365 East North Avenue, Carol Stream, Ill. 60187.

Single row cigarette cartons which are dimensioned to contain one row of five cigarette packs (each pack usually containing twenty cigarettes, the packs arranged so that the front long walls of the packs are in the same plane and the back long walls are in a parallel plane spaced from the front long walls), i.e., five-pack cartons, are also known in the art. However, although machinery exists for manufacturing such cartons, machinery does not exist for stamping the cigarette packs contained in such cartons. Consequently, such cartons are usually put into scored, glued, and collapsed cartons to be hand-stamped (as is done currently), or would have to be secured together in pairs to be run through the existent tax-stamping equipment in which packs in double row cartons are stamped. To assure that the tax stamp is properly registered, the means for securing the cartons must be strong enough to keep the cartons together such that they are not sheared apart by the vertical rollers of the tax-stamping machines which roll along the vertical walls of the cartons to transfer the cartons between the various stages of the process.

If two narrow cartons are to be secured together, the means for securement must allow for later separation of the cartons, if desired, by the retailer or consumer. For marketing purposes, once separated, the two cartons should have little or no trace of the means for securement which would disfigure the outward appearance of the cartons. Furthermore, the cartons should be sealed such that they may be opened to apply the required tax stamp and later resealed without disfiguring the outward appearance of the cartons.

SUMMARY OF THE INVENTION

It is therefore an object of this invention to provide means for securing two cartons together to form a dual carton which may be later separated and sealed with the adhesive used for joining the cartons and for sealing the dual carton, for sale of the individual cartons.

It is another object of this invention to provide a means for securing cartons together for passing through tax-stamping machinery, such that the cartons are not sheared apart by the vertical rollers of the tax-stamping machines which roll along the vertical walls of the cartons to transfer the cartons between the various stages of the process, and such that a tax stamp may be properly registered on the packs.

It is yet another object of this invention to join two cartons together to form a dual carton which outwardly resembles an individual carton.

It is a further object of this invention to provide a means for making a clean separation between the individual cartons if desired for sale as an individual carton instead of as a multiple unit carton.

These and other objects of the invention are accomplished in accordance with the principles of the invention by joining two cartons together along the tops of abutting walls with adhesive which remains tacky after the cartons are separated and remains adhered to one of the cartons. The cartons have top and tuck-in flaps which are overlapped and joined with similar adhesive applied to the tuck-in portion of the flap of the other of the cartons to seal the cartons in the dual carton configuration. Once the cartons are separated, the adhesive along the top of the wall of the first-mentioned carton is used to seal the first carton, and the adhesive on the tuck-in portion of the flap of the second-mentioned carton is used to seal the second carton.

DETAILED DESCRIPTION OF THE INVENTION

Blank 100, shown in FIG. 1, is an illustrative blank for forming cartons in accordance with this invention. Blank 100 is preferably formed from a substantially stiff material such as cardboard or paperboard, and has a front panel 10, a rear panel 12, and a bottom panel 14, which are each folded along fold lines shown as broken lines not individually labeled, to form a carton. Top flap/extension panel 16 forms the top wall, and tuck-in flap/extension panel 18 is preferably releasably secured to the exterior of the carton, on the outside of wall 10. Tuck-in flap 18 may also be tucked into the filled carton formed from blank 100, between the cigarette packs and wall 10. Preferably top flap 16 extends the entire distance between panels 10 and 12 when blank 100 is folded into a carton. Tuck-in flap 18 preferably is the same dimension as top flap 16, for reasons as will be explained below. Dust flaps 24 and 26 are folded preferably perpendicular to bottom wall 14. Panels 20b and 22b are then folded adjacent dust flaps 24 and 26, respectively, and substantially perpendicular to panel 12. Preferably dust flaps 24 and 26 include cut edges 25 and 27, respectively, and panels 20b and 22b include cut edges 21 and 23, respectively. When included, edge 21 aligns with edge 25 and edge 23 aligns with edge 27 so that panel 20b lies in the same plane as dust flap 24, and panel 22b lies in the same plane as dust flap 26. Panels 20a and 22a are folded over panels 20b and 22b, respectively, to complete side wall 20, formed by panels 20a and 20b, and side wall 22, formed by panels 22a and 22b.

The connection of two five-pack cartons 30, 32, each formed from a blank similar to blank 100, is shown in FIG. 2. Cartons 30, 32 are joined along front walls 10, hereinafter referred to, in connection with the dual carton, as interior walls 11, with adhesive dots 50 to form a dual carton. Preferably only one carton, here carton 30, has adhesive 50 applied to interior wall 11, while the other carton, here carton 32, has adhesive dots 50 applied to tuck-in flap 18. Once connected, the cartons are sealed by folding panel 16 of carton 30 over carton 30, panel 18 of carton 30 over carton 32, panel 16 of carton 32 over panel 18 of carton 30, and panel 18 of carton 32 over panel 16 of carton 30. Adhesive 50 joins panel 18 of carton 32 to panel 16 of carton 30 to thereby seal the dual carton. Adhesive 50 is any adhesive known in the art which remains tacky even after the surfaces which the adhesive bonds together are separated. Hence, after cartons 30, 32 are separated for individual sale, carton 30 may be sealed by adhering flap 18 of carton 30 to wall 11 of carton 30 with adhesive 50 left on wall 11. Carton 32 likewise may be sealed by adhering flap 18 of carton 32 to wall 11 of carton 32 with adhesive 50 left on flap 18. The type and method of application of adhesive 50, and the preparation of the surfaces of wall 11 and flap 18 to which adhesive 50 is applied are selected to control the desired transfer, release, and adherence of adhesive 50.

Although the five-pack cartons of FIG. 2 are shown filled with bundles of cigarette packs 34 before being joined along walls 11, cartons 30, 32 may be joined and later filled with bundle 34, as shown in FIG. 3. When the cartons are filled in the dual carton configuration, packs 36 are arranged in a bundle 34 of two rows of five packs per row. The cartons are shown joined along interior walls 11, with flaps 17, formed from panels 16 and 18, open, prepared for insertion of bundle 34. Rear walls 12 remain visible after connection of cartons 30, 32, and are hereinafter referred to as exterior walls 13. Because "a" panels 20a and 22a are preferably folded over "b" panels 20b and 22b, the free edges of each of the "a" panels of the side walls faces inwardly, i.e., the free edges lie adjacent interior walls 11, when cartons 30, 32 are joined. In this configuration, the free edges of the "a" panels are not readily accessible and thus are relatively safe from being accidentally lifted from their place adjacent the "b" panels.

Packs 36 are preferably arranged in two rows of five packs per row with the short walls of adjacent packs facing each other and the long walls of the packs arranged in parallel planes such that the front walls of each row are in a first single plane and the rear walls of each row are in a second single plane spaced from and parallel to the first single plane. Furthermore, it is desirable to place packs 36 in their respective cartons such that their front walls (defined by the orientation of printed matter on the exterior surface of the walls) face interior walls 11 of cartons 30, 32.

Although adhesive 50 preferably sufficiently joins cartons 30, 32, additional securing means such as band of material 44, or carrier means bearing adhesive such as labels 40, 42, or 43, may be used, as well. Band 44 may be formed of either transparent or opaque material such as plastic or paper. Cartons 30, 32 are shown in FIGS. 4 and 5 joined along interior walls 11 with adhesive 50 (shown in FIG. 2), and further joined along side walls 20 and 22 with labels 40, 42, and 43, and band 44. Label 40 is positioned across side walls 20 and 22 of cartons 30 and 32. Labels 42 and 43 are shown in FIG. 5, positioned across the bottom walls and corners, respectively, of the cartons. Label 40 preferably includes a line of weakness such as perforated line 41, positioned substantially above and parallel to the walls across which label 40 is placed, to facilitate later separation of cartons 30, 32 along line 41. Such lines of weakness may also be provided along labels 42 and 43, and positioned as line 41 is.

Label 40 or 42 may optionally bear pricing indicia such as Universal Product Code (U.P.C.) indicia for the automatic pricing of the dual carton, such as described in co-pending, commonly assigned U.S. patent application Ser. No. 07/792,617, filed Nov. 15, 1991, which is hereby incorporated by reference in its entirety. The indicia are preferably positioned such that they are rendered unreadable by automatic scanning equipment upon separating the cartons so that a consumer is not charged the price of a dual carton for a single carton. Such labels may be applied across any adjacent coplanar walls of cartons 30, 32. Preferably, if pricing indicia are included, only one label bearing pricing indicia is used. Alternatively, indicia for the automatic pricing of the dual carton such as indicia 45, may be printed on band 44. Pricing indicia for the individual cartons are preferably printed on interior walls 11, and are only accessible to automatic scanning equipment when cartons 30, 32 are separated.

The joined cartons are filled with cigarette bundle 34 and are ready for temporary closing with adhesive 50. Because adhesive 50 is applied along the inner side of flap 18 of carton 32 in FIG. 3, the interior wall 10 bearing adhesive 50 along its upper end is wall 10 of carton 30 (not shown).

Top flaps 17 of joined cartons 30 and 32 are shown overlapped in FIG. 5. In this embodiment, tuck-in flap 18 of carton 30 bears adhesive 50 and is positioned over and releasably secured to top flap 16 of carton 32. Thus, the upper end of wall 10 of carton 32 (not shown) bears adhesive 50 for joining the cartons. Cartons 30, 32 are joined as shown in FIG. 5 before tax-stamping. If desired, cartons 30, 32 may be similarly joined after tax-stamping for sale as a dual carton. Alternatively, the cartons may be separated for individual sale. In this case, the tuck-in flap bearing adhesive is either secured to the exterior of the carton or tucked inside. The tuck-in flap not bearing adhesive is secured to adhesive remaining on the formerly interior wall.

Although dots of adhesive are shown, adhesive may be applied in lines or any other convenient pattern, in quantities sufficient to join or seal the cartons.

Although cartons 30, 32 are described as each dimensioned to hold one row of five cigarette packs, they may lengthened or shortened to hold more or fewer than five packs. Furthermore, it will be appreciated that these concepts may be applied to the connection of cartons of other configurations for which distributors commonly have tax-stamping machinery.

It will be appreciated that references to cigarette cartons and cigarette packs are not limited to only rectangular cartons and packs, but are intended to include all configurations which are available to consumers. Cigarette cartons include cartons with windows, cartons with rounded edges, and other configurations which are designed to be passed through tax-stamping equipment. Cigarette packs include such packs as oval packs, packs with rounded edges, and other non-rectangular shapes.

It will be appreciated that references to tax-stamping machinery are intended to include any existing equipment which is readily available to distributors, and modified versions.

It will be appreciated that the directional references "top," "bottom," "front," and "rear" do not limit the respective panels to such orientation, but merely serve to distinguish these panels from one another.

It will be understood that the foregoing is merely illustrative of the principles of the invention, and that various modification can be made by those skilled in the art without departing from the scope and spirit of the invention. For example, such connection of cartons may be applied to any cartons, and is not limited to cigarette cartons. The described embodiments are presented for the purpose of illustration rather than limitation, and the present invention is limited only by the claims which follow.
