Flip top carton

Abstract

A flip top carton is formed from cut and scored paperboard and is of the type where a telescoping cover member is movable with respect to an open top carton receptacle from a closed position to an open position. A connection is provided between the open top receptacle and the cover, so that sliding movement of the latter causes such opening and closing movement, such connection including first, second and third operator members foldably connected to each other and extending from the back wall of the open top receptacle. The first operator is foldably connected to the back wall of the receptacle and the third operator member is secured to the inside of the top cover panel, the first and second operators undergoing folding when the cover is moving in the opening and closing thereof.

The improved flip top carton according to the present invention is denoted generally by the reference numeral 10, and includes an open top receptacle CR formed from a cut and scored blank 10A. A cover C for the carton 10 is formed from a cut and scored blank 10B seen in FIG. 3, and when the two blanks 10A and 10B are assembled and joined as will be described, the structure seen will be formed.

Blank 10A for forming the open top receptacle CR consists of a front panel 11, a bottom panel 12 and a back panel 13, these being joined along fold lines 14 and 16. Side panels 17 are foldably connected along fold lines 18 to opposite sides of the back panel 13 and are folded into face-to-face relationship with outer side panels 19 foldably connected to the front panel 11 along spaced fold lines 21, the panels 17 and 19 being glued together in conventional fashion. Flaps 22 extend from the lower ends of each of the side panels 17 into lapping engagement with the interior of the bottom panel 12, the flaps 22 being glued thereto.

Cover C, which is formed from blank 10B consists of front panel 26 serially connected to a side panel 27, a back panel 28 and an opposite side panel 29 along score lines 31, there being a closing panel 32 connected along a fold line 33 to one edge of the front panel 26 and glued to the outer side panel 29. A top panel 34 is foldably connected to the back panel 28 along a fold line 36, and a front panel 37 is foldably connected to a front movable cover panel 37 foldably connected to the top cover panel along a fold line 38. Flap elements 39 extend one to each side of the front cover panel 37 and are foldable along continuations of the fold line 38 and secured against the inside of the front movable panel 37. The two flaps 39 are coextensive with triangular shaped side panels 41, each having a mitered edge 42, and being adapted to move into contact with mitered edge 42 of the panels 27, 29 and 32 when the cover is in position as seen in FIG. 5.

Cover C is adapted to be in telescoping relationship with the open top receptacle CR, and structure is provided whereby the cover C is arranged to have an operative connection with the open top receptacle CR during sliding movement of cover C with respect to open top container receptacle CR whereby the cover C is moved between open and closed positions.

First, second and third operator members indicated by the reference numerals 43, 44 and 46 respectively are foldably connected to each other, first operator member 43 being connected to the back wall 13 of receptacle CR along a fold line 47. Second operator member 44 is foldably connected to the first operator member 43 along spaced fold lines 48, these being interrupted by a cut line 49. The third operator member 46 is foldably connected to the second operator member 44 along a fold line 51, and the third operator member is glued or otherwise secured to the underside of top movable panel cover 34.

As seen in FIGS. 5 and 6, when cover C is slid downward toward the bottom of the open top receptacle CR the top movable cover panel 37 and the top movable panel cover 34 are rotatably and translatively moved to the open position shown, the first and second operator members 43 and 44 being folded toward each other. As seen in FIG. 5 when the cover C is moved away from the bottom 12, the closed position results, and the two operator elements 43 and 44 are folded away from each other to adopt susbstantially straight line positions as seen in FIG. 5.

Referring now to FIG. 7, there is shown another embodiment of the invention where the movable cover C is formed from a blank C2 of somewhat different configuration than the blank seen in FIG. 3. In this form of the cover C2, the blank includes a lower front panel 61, a front movable cover panel 62, a top movable cover panel 64 and a back cover panel 67. Panels 61 and 62 are joined along a score line 63; panels 62 and 64 are joined along a score line 66; and panels 64 and 67 are joined along a score line 68.

Panel 61 has side panels 73 foldably connected to front panel 61, and rear panel 74 has side panels 74 foldably connected thereto along continuations of the score line 71. The panels 73 and 74 are adapted to be joined together, and flaps 72 are folded against the inside of the front movable cover panel 62 by glue or the like. Mitered panel 69 is connected between the flaps 72 and top cover panel 64 along the score lines 66 and 71, and the mitered panels 69 are adapted to over lie the side panels 73.

As with the embodiment previously described, the cover C2 is adapted to be joined to the receptacle CR in the same fashion, the third operator member 46 being glued to the inside of the top cover panel 64.

When the product is to be used, and the cover C2 moves with respect to the open top receptacle CR, the score line 63 which is a half perforated line is severed, and container 10 opens as previously described.

Referring now to FIG. 9, there is shown another embodiment of the invention referred to by reference numeral 80 where the movable cover C is formed from a blank C3 of a slightly different configuration than the blanks previously seen. In this form of the cover C, the blank C3 includes a lower front panel 81, a front movable cover panel 82, a top movable cover panel 84 and a back cover panel 87. Panels 81 and 82 are not joined in this instance, as with the embodiment of FIG. 8; panels 82 and 84 are joined along a score line 86; and panels 84 and 87 are joined along a score line 88.

Panel 81 has side panels 83 foldably connected thereto and rear panel 87 has a side panel 95 foldably connected thereto along continuations of a score line 91. One of the panels 83 and 95 are adapted to be joined together to define a tube, and flaps 92 are folded against the inside of the front movable cover panel 82 by glue or the like. Mitered flaps 89 are foldably connected to front panel 82 and are folded and glued against flaps 92 to complete side walls of cover C3.

In this embodiment of the invention the third operator member 46 is held between front cover panel 82 and an inner flap 96 foldably connected to panel 82, these members being secured together by glue.

The lower front panel 81 is stiffened by flange elements 97 and 98 foldably connected along a fold line 99, element 97 being foldably connected to panel 81 along a fold line 101. Elements 97 and 98 are folded as seen in FIGS. 12 and 13 upon themselves and behind front panel 81.

Lower front panel 81 and front movable cover panel 82 move into abutting relationship as seen in FIG. 12 upon closing of the carton.
