Oct. 16, 1962 R. GUYER 3,058,646

RECLOSABLE CARTONS Filed April 25, 1959 INVENTOR Reyna/o4; Guger ATTORNEY Patented Oct. 16, 1962 3,058,646 RECLOSABLE CARTONS Reynolds Guyer, White Bear Lake, Minn., assignor to Waldorf Paper Products Company, St. Paul, Minn., a corporation of Minnesota Filed Apr. 23, 1959, Ser. No. 808,372 Claims. (Cl. 22944) This invention relates to an improvement in reclosable cartons and deals particularly with a type of carton which may be used for containing cigarettes or the like and from which the contents may be dispensed when desired.

An object of the present invention resides in the provision of a carton which is formed in two complementary sections which are hingedly connected together. The carton includes a partial liner which is secured to one of the sections and which telescopes into the other section. This liner is arranged to hold the contents of the package contained in one carton section when the other section is hinged away so that the contents of the package may be removed.

A feature of the present invention resides in a package which in preferred form is formed in two sections which are separable alon g cut lines extending across the front panel, the top panel, and the rear panel. The bottom panel is hinged so that the two sections may be folded into edge abutting relation or may be hinged apart to disclose the contents.

A further feature of the present invention resides in the provision of a carton which is formed of a blank which includes two half carton sections which are connected by a wall including a hinge line by means of which the two carton sections are connected. When formed, the two sections abut together to form the complete enclosure.

An important feature of the present invention lies in the provision of a simple and effective means of holding the carton either in open or in closed position. A pair of tabs are cut from a portion of the liner panel and the ends of these tabs is adhered to the pivotally supported closure section. The anchoring of these tabs to the closure section acts to normally hold this closure section in closed position. However, as the closure section is hinged toward open position, the tabs fold in a manner to cause the side walls of the closure section to be flexed outwardly thus placing the tabs under compression until the cover section is in fully open position. Due to the action of these tabs, resistance is created to folding the closure section either out of closed position or out of fully opened position.

These and other objects and novel features of the pres ent invention will be more clearly and fully set forth in the folowing specification and claims.

In the drawings froming a part of the specification:

FIGURE 1 is a perspective view of the carton in closed position.

FIGURE 2 is a perspective view of the carton in open position.

FIGURE 3 is a cross sectional view through a portion of the carton in open position, the location of the section being indicated by the line 33 of FIGURE 2.

FIGURE 4 is a diagrammatic view of the blank from which the outer portion of the carton is formed.

FIGURE 5 is a diagrammatic view of the blank from which the lining portion of the carton is formed.

The completed carton A is formed of the blank B illustrated in FIGURE 4 of the drawings, and the blank C illustrated in FIGURE 5 thereof. The blank B is formed with a bottom panel which is foldably connected along fold lines 11 and 12 to side wall panels 13 and 14 respectively. The side wall panel 13 is foldably connected along a fold line 15 which is at right angles to the fold lines 11 and 12 to a rear panel 16; and the side wall 13 is also connected along a fold line 17 which is parallel to the fold line 15 to a front wall panel 19. The terms front, rear and side wall panels are merely used as a means of designating the various parts to simplfy the description.

The side wall 14 is foldably connected along a fold line 20 which is aligned with the fold line 15 to a rear wall panel 21. The side Wall 14 is also connected along a fold line 22 which is aligned with the fold line 17 to a front panel 23. As is indicated in the drawings, in the particular arrangement illustrated, the front and rear panels are tapered or wedge shaped in form, the rear panels 16 and 21 having mating inclined edges 24 and 25, and the front wall panels 19 and 23 having mating inclined edges 26 and 27. In the closed position of the carton, the edges 24 and 25 abut and in a similar manner the inclined edges 26 and 27 of the front wall panels abut.

A fold line 29 extends across the bottom panel 10 parallel to the fold lines 11 and 12 and spaced therefrom. Bottom flaps 30 and 31 are connected to the rear panel 16 and front panel 19 respectively along aligned fold lines 32 and 33. The width of the flaps 30 and 31 is substantially equal to the width of the bottom panel 10 and the length of these flaps 30 and 31 is equal to the distance between the fold line 11 and the intermediate fold line 29. The top closing flaps 34, 35 and 36 are foldably connected to the upper edges of the walls 13, 16 and 19 respectively along a fold line 37.

Bottom flaps 39 and 40 are foldably connected to the lower edges of the rear panel 21 and front panel 23 along aligned fold lines 41 and 42 which are substantially aligned with the fold line 12. The width of the flaps is equal to the width of the bottom panel 10 and the length of the flaps in a direction parallel to the fold lines 41 and 42 is substantially equal to the distance between the fold line 12 and the intermediate fold line 29. Top closing flaps 43, 44 and 45 are hin gedly connected to the upper edges of the panels 14, 21 and 23 respectively along a fold line 46.

In the formation of the carton blank B, the rear and front walls 16 and 19 are folded upwardly at right angles to the side wall panel 13 and the flaps 30 and 31 are folded at right angles to the walls 16 and 19 into overlapping relation. The'blank is also folded along the fold line 11 so that the flaps 30 and 31 overlie or underlie the portion of the bottom panel 10 between the fold line 11 and the intermediate fold line 29. When the bottom flaps 30 and 31 are secured in face contact with the bottom panel 10, this portion of the carton is completed.

In a similar manner, the rear and front walls 21 and 23 are folded into right angular relation with the side wall 14, the bottom flaps 39 and 40 are folded into overlapping relation and these flaps are adhered in face con tact with the portion of the bottom panel 10 between the fold line 12 and the intermediate fold line 39. The upper end of the carton is closed by folding the top closing flaps 34, 35 and 36 in face contact and folding the top closing flaps 43, 44 and 45 in parallel face contact. When thus formed, a complete rectangular carton is formed including two sections which are in edge abutting relation.

The liner panel C is secured in place to the carton section 47 which is on one side of the intermediate fold line 29 and extends into the other section 49 which is on the opposite side of the intermediate fold line 29. The liner C includes an intermediate panel 50 which is of proper width to fit within the carton section 49, the panel 50 being foldably connected along parallel fold lines 51 and 52 to a rear wall panel 53 in a front wall panel 54.

3 The panel 53 is of a Width substantially equal to the combined width of the rear panels 16 and 21 and the front panel 54 is substantially equal in width to the combined width of the front panels 19 and 23 of the blank B. The rear wall panel 53 and front wall panel 54 are of substantially the same weight as the front and rear wall panels of the blank B and these panels are secured by adhesive or other suitable means to the inner surface of the rear panel 16 and the front wall panel 19. When thus arranged, the liner projects into the section 49 and lies in surface contact with the walls 14, 21 and 23 when the carton is in closed position.

In preferred form, the upper edge of the liner C is notched as indicated at 55. This notch extends across the wall 50 and into the rear and front walls 53 and 54 throughout the width of section 49 at this elevation. In other words, the ends 56 and 57 substantially coincide with the edges of the two sections when the carton is closed.

The broken lines 59 and 60 across the rear wall panel 53 and front wall panel 54 defines the portion of these panels which is secured to section 47 of the carton and the portion which projects from section 47. A pair of tabs 61 and 62 are cut from the portions of the panels 53 and 54 which lie between the broken lines 59 and 69 and the fold lines 51 and 52. These tabs 61 and 62 are defined by short cut lines 63 and 64 which extend substantially along the broken lines 59 and 6t relatively long cut lines 65 and 66 which are substantially in alignment, and shorter cut lines 67 and 69 at the other ends of the cut lines 63 and 64 and parallel to the cut lines 65 and 66. The tab 61 is foldably connected to the panel 53 along a fold line 70 which is directed toward the juncture between the broken line 59 and the lower edge of panel 53. The tab 61 is centrally divided by an additional fold line 72.

The tab 62 is similarly connected to the panel 54 by a fold line 73 which is directed toward the juncture '74 between the imaginary broken line '60 and the lower edge of the panel 54. The tab 62 is provided intermediate its ends with an additional fold line 75 also directed toward the point 74.

In practice, the end portions of the tabs 61 and 62 outwardly of the intermediate fold lines 72 and 75 are adhered to the wall panels 21 and 23 of section 49 of the carton. As a result, the two sections are normally held in the closed position illustrated in FIGURE 1 of the drawings by these tabs 61 and 62. However, if the upper portions of the two sections 47 and 49 are swung apart along the fold line 29 to the position illustrated in FIGURE 2, the connecting portions-of the tabs 61 and 62 which are between the intermediate fold lines 72 and 75 and the inner fold lines 70 and 73 must swing outwardly in order to fold. These tabs accordingly flex the side walls 21 and 23 of the carton section 49 outwardly, placing the connecting portions of the tabs under compression. As the connecting portions of the tabs fold past 90, the resiliency of the side walls will cause the section 49 to swing completely open into the position shown in FIGURE 2. The closing of the carton creates a similar force and the connecting portions of the tabs must again swing outwardly, causing the side walls of the carton section 49 to bow outwardly. As the tabs fold past 90, the compressive force created by the side walls will swing the carton section 49 into fully closed position illustrated in FIGURE 1 of the drawings.

As indicated in FIGURE 2, the package of cigarettes which is contained virtually fills the carton when closed but one corner of the wrapper projects above the notched portion 55 of the liner member and forwardly of the carton section 47 where the contents of the package are readily available.
