7 Claims. (Cl. 229-37) This invention relates to a carton having an integral lid at its top, particularly that type of carton or box, used in packaging commodities which are dispensable from the carton over a period of time. For example, cigarettes, cigars, certain candies, and the like, are carried about in their package and dispensed one or a few at a time, as distinguished from items which are entirely removed from their packages at one time.

Such cartons serve, then, not only as a package but also as a dispenser, and must be easily openable, give ready access to the contents, be able to resist crushing and other deformation when carried on the person, and also providing a tight closure when so carried.

it is a primary object of this invention to provide such a carton wherein the entire carton, together with its lid, is formed from a single blank of sheet material, and wherein there is a minimum of waste when cutting the carton blanks from a sheet of material.

Another object of the invention is to provide such a carton, including inner and outer panels forming inner and outer body members, from a single blank which is easily folded into assembled position, and which provides a sturdy carton resistant to deformation.

A further object of this invention is to provide such a carton wherein the inner and outer members have an integral connection adjacent the bottom of the assembled carton, thereby preventing accidental severance or removal of the inner member and facilitating manufacture by keeping both portions at all times in proper orientation.

Additional objects and advantages of the invention will be apparent from the following description, the accompanying drawings, and the appended claims.

In the drawing Fig. 1 is a plan view of the blank from which the carton of this invention is formed;

Fig. 2 is another view of the blank of Fig. 1 with the panels of the inner carton member folded over upon the outer carton panels;

Figs. 3 and 4 are views showing the steps of folding the blank of Fig. 2 into flat tubular form;

Fig. 5 shows the tubular blank of Fig. 4 in erected condition preparatory to folding the end flaps thereof;

Fig. 6 is a vertical section through the assembled carton, with the open position of the lid shown in dotted lines;

Fig. 7 is a perspective view of the finished carton with the lid open;

Fig. 8 shows a modified carton blank in accordance with the invention; and

Fig. 9 illustrates the blank of Fig. 8 with the panels of the inner carton member folded upon the outer carton panels.

Referring to the drawings, which illustrate preferred embodiments of the present invention, and particularly to Fig. l, the blank for the carton provided by this invention includes a series of four outer panels longitudinally arranged with respect to each other and separates Patent D rated by suitable score lines to provide a front panel 10, side panels 11 and 12 and'a rear panel 15. Glue flap 16 extends from the free edge of side panel 11, and is adapted to be fixed to the free edge of rear panel 15 to complete the main body of the carton, as will presently be described.

The front and side panels are slit along a continuous line 18 transversely of fold panel 10 and bias cuts 19 across the side panels 11 and 12 respectively, thereby providing upper portions 20 and 21 on the front and side panels respectively which are separated fiom the remainder of these panels. A transverse score line 25 extends across rear panel 15 from the end of bias cut 19, and another score line 26 extends across glue flap 16, to be superimposed upon score line 25 in the assembled carton. Suitable top end flaps 27 are integrally hingedly connected to front and side panel portions 20 and 21, and to the top of rear panel 15, along fold lines 28, and are separated from each other by cuts indicated by solid lines 29.

Another fold line 30 extends across the bottom of the blank, at the lower end of panels 10, 11, 12 and 15,

providing an integral hinged connection for bottom end flaps 32, 33 and 34. In addition, an inner front panel 35 having extended connecting portions 36, which in blank form completely surround the bottom end flap 32,

is hingedly connected to the outer front panel 10 along the intersection of these extended portions 36 and panel 19 at fold line 30. The other end flaps 33 and 34 are separated from each other and from the connecting portions 36 along cuts indicated by the solid lines 38 in Fig. l, and the bottom end flap 32 is separated from connecting portions 36 and the adjacent part of inner front panel 35 along out line 39.

The length of inner front panel 35 is such that when it is folded up about line 30 into superposition upon the inner face of outer front panel 14) and its upper portion 20, the free edge of inner front panel 35 falls just short of fold line 28. This relation is best seen in Fig. 2, wherein the inner front panel has been folded into such position. Inner side panels 40 extend from the opposite side of inner front panel 35 and are foldably connected thereto along score lines 41. These inner side panels 40 are superimposed upon outer side panels 11 and 12 when the inner front panel is folded up as in Fig. 2, and adhesive, applied in a transverse strip 44 across the face of inner panels 35 and 40 which engages outer panels 10, 11 and 12, holds there panels in superimposed relation, as seen in Fig. 2.

Furthermore, the inner member extends substantially into the lid in its closed position, and the upper edges of the connection panels 35 and 40 provide corners on the inner member, as seen in Fig. 7, which are engaged by inner surfaces of the front lid portion 20 during opening and closing movements of the lid. Thus, there is a frictional resistance to opening and closing of the lid and consequently the lid is retained in closed position unless a force is exerted to move it to open position.

Referring to Figs. 3 and 4, the side panel 11 is folded onto the inner front panel 35, as seen in Fig. 3, and adhesive is applied to the then upwardly facing side of glue flap 16. In Fig. 4, the rear panel 15 and its connected end flaps 27 and 35 have been folded over from right to left'along the fold line connecting panels 12 and 15, and the free edge of rear panel 15 rests upon and adheres to glue flap 16, thus providing a flattened tubular form of the carton, which is erected into open tubular form as shown in Fig. 5 for closing of the end flaps to provide top and bottom walls.

Referring to Fig. 5, the carton is shown in erected tubular form, and the bottom end flaps 33 have begun to swing inwardly across the bottom of the open tubular form. When these flaps 33 extend across the bottom of the carton the end flap 32 is folded downwardly upon them, as indicated by arrow 45, and finally the lower end fla 34 is folded upwardly. andzadhered toflap 32,- in the direction indicated by mower, incomplete thelhottom wall which is shown generallyjat 47 in Fig.6. A top wall dsiis lthen formed indike manner, withlthe top .end

flaps folding'inwardly first in the direction indicatedby arrows 56, and then in sequence, first by the arrow 51, and then by the arrow 52." These top end flaps are secured together by :suitable adhesive to form the finished top wall 43. j i V 1 The finished carton, shown in section in Fig. 6 and in perspective inFigpT, includes an inner member provided'by' inner front panel 35 and inner side panels and an outer ormain body member provided by front panel 10,;side panels 11 and12, and rear panel 15. The upper portions 20 and,21; of, the outer member, being separated therefromalong'slits v18, 19 provide, in cc,

operation with the top wall'48, .a lid which .is hinged about score line 25, and movable between an open posi 'tion indicated in dotted lines in Fig. 6, and the closed position shown in full lines. -If desired, theupper rear corner of inner side panels 40 may be rounded as at 55 to Ifacilitatethe opening and closingiof thelid; 7 .Referring to Figs. fixand 9, there is shown a carton blank similar to that of Figs. 1 and 2, and like parts are indicated by'liketreference numerals. In the modification of FigsQS'and 9, however, the inner member is prosequence of'assembling'the blank shown in Fig. 9 is' exactly the same as the procedure above described in connection with Figs. 3, 4 andS. i

The present invention thus provides a carton having an integral lid thereon which is formed from a single compact blank, and which, due to its double-walled construction, is liighlyresistant to crushing or other deformation. This carton is 'inexpensive'to manufacture, simple to assemble, and affords more than adequateprotection for the commodities to be packaged therein.
