RECLOSABLE FOLDING CARTON Filed 001.- 26, 1967 INVENTOQ Zoe day/v u MA/lO/V 24a- BY WM 24 24b 25 20b ATTORNEY United States Patent 3,438,566 RECLOSABLE FOLDING CARTON John V. Mahon, Landsdale, Pa., assignor to Container Corporation of America, Chicago, 11]., a corporation of Delaware Filed Oct. 26, 1967, Ser. No. 678,436 Int. Cl. B6511 /70, 5/22 US. Cl. 229-51 7 Claims ABSTRACT OF THE DISCLOSURE A paperboard folding carton having a plurality of walls joined to form a box-like structure having an Opening on one side and a pair of inner and outer panels hinged to opposite walls and folded into overlapped relation to close the opening, one of the panels having a partially detachable tab which is insertable between a pair of tabs on the other panel to effect a reclosure of the carton.
This invention relates to reclosable folding paperboard cartons and more particularly to an improved closure panel arrangement for opening and reclosing the carton.
An object of the invention is the provision, in a carton of the type described, of a pair of overlapping closure panels which are glued together in certain areas and which have other unglued areas defining reclosure tabs.
A more specific object of the invention is to provide, in a carton of the type described, an inner closure panel with a pair of opposed tabs cut therefrom and hinged thereto with abutting free forward edges and an outer closure panel with a tab which is partially detached upon opening of the carton and which has a portion which is insertable between the abutting edges of the tabs of the inner closure panel upon reclosure of the carton.
These and other objects of the invention will be apparent from an examination of the following description and drawings, wherein:
FIGURE 1 is a perspective view of a portion of a paperboard carton having closure panels embodying features of the invention, as seen before the closure panels have been initially closed and sealed;
FIGURE 2 is a view similar to FIGURE 1 but showing the panels after they have been initially closed and sealed;
FIGURE 3 is an enlarged fragmentary plan view of the portion of the structure illustrated in FIGURE 2 showing the closure panels after they have been initially closed and sealed;
FIGURE 4 is view similar to FIGURE 3 but showing the closure panels after the carton has been opened initially and then reclosed;
FIGURES 5 and 6 are fragmentary sections taken on lines 5-5 and 66 of FIGURES 3 and 4, respectively, and
FIGURE 7 is a plan view of the blank from which the carton illustrated in the other views may be formed.
It will be understood that, for purposes of clarity, certain elements have been intentionally omitted from certain views where they are believed to be illustrated to better advantage in other views.
Referring now to the drawings for a better understanding of the invention, and particularly to FIGURES 1 and 7, it will be seen that the carton, indicated generally at C, in FIGURE 1, may be formed from the unitary blank B of foldable paperboard illustrated in FIGURE 7.
Still referring to FIGURES l and 7 it will be seen that carton C includes a first minor side wall 10, a first major side wall 12, a second minor side wall 14, a second major side wall 16, and a glue strip 18, which are serially interconnected to form a tubular structure open at opposite ends.
"ice
One end, the bottom as shown in FIGURE 7, may be closed by a plurality of end closure flaps and panels 20, 22, 24, and 26 which are hingedly attached to the lower edges of side walls 10, 12, 14, and 16, respectively.
The opposite end of the container is provided with generally similar closure flaps and closure panels which, as best seen in FIGURE 7, comprise flap 30, panel 32, flap 34, and panel 36 which are hingedly attached to the side walls 10, 12, 14, and 16, respectively.
Still referring to FIGURES 1 and 7, and particularly to the inner and outer closure panels 32 and 36, respectively, which represent the novel feature of the invention, it will be seen that inner closure panel 32 has cut there from and formed therein a pair of integral first and second locking tabs 40 and 50, respectively, which are disposed adjacent each other.
First tab 49 is defined by a free front edge 42 which preferably extends generally parallel to the hinge line of the panel, a rear hinge line 44, which may be perforated and which also preferably extends parallel to the hinge line of the panel, and free side edges 46 which connect the ends of the front and rear edges.
In a similar manner second tab 50 is defined by a free front edge 52, which preferably extends generally parallel to the hinge line of the panel, a rear edge 54 which is hinged to the panel on a hinge line preferably extending generally parallel to the hinge line of the panel, and free side edges 56 which interconnect the ends of the front and rear edges of the tab.
As front edge 52 of tab 50 is shorter than front edge 42 of tab 40, there are provided a pair of opposed shoulders 58 in panel 32 adjacent opposite sides of tabs 40 and 50.
Fixed tab 60 is defined by a free front edge 62, a rear edge 64 which is hinged to the remaining portion of the panel 36, and free side edges 66 which connect the ends of the front and rear edges of the tab. Preferably both the front and rear edges extend in the same general direction as the hinged line of the panel.
The partially detachable tab 70 is defined by a free front edge 72, a rear edge 74 which is hinged to side walls 16 and is the same hinge line which constitutes the hinge line of panel 36, and a pair of free side edges 76 which interconnect the ends of the front and rear edges of the tab. It will be noted that side edges 76 are defined by cuts which form weakened lines of tear to permit the tab to be detached from the remaining portion 80 of the panel 36 merely by pulling or tearing the tab away. The tab still remains attached to side wall 16, however.
It will be understood that normally the carton will be formed and glued as a tube by the carton manufacturer and shipped to the user in that condition. The user, after closing and gluing the bottom end of the carton, will fill the carton and then close the top end of the carton in the manner hereinafter described.
In closing the carton closure flaps 30 and 34 are folded into the carton, as shown in FIGURE 1, and inner closure panel 32 is folded over at right angles to side wall 12 to overlie closure flaps 30 and 34. Outer closure panel 36 is then folded at right angles to side wall 16 to overlie inner closure panel 32. The glue pattern 38, as illustrated in FIGURE 1, permits the inner and outer panels to be adhesively secured to each other in the areas of the panels other than where the locking tabs of the respective panels are located.
To open the carton, outer panel fixed tab 60 is depressed to permit the insertion of a finger under detachable tab 70 which is then pulled up and ripped away from the remaining portion 80 of the outer panel. At this point the remaining portions of all of the panels and flaps can be lifted to open the carton. Upon reclosure of the carton, flaps 30 and 34 are again folded at right angles to side walls and 12 and inner closure panel 32 is folded at right angles to side wall 12 to overlie flaps 30 and 34. At this point it will be understood that the remaining portion 80 of outer closure panel 36 is bonded to the corresponding surface of inner closure panel 32 and therefore is in effect a part of the panel. Thus the only remaining portion of the original outer panel 32 is the detachable tab 70 which is then folded down to overlie inner panel 32 and then is depressed past the plane of panel 32 to the point at which the front edge 72 is permitted to override the front edge of inner panel second tab 40 and slip past shoulders 58 and between the abutting front edges 52 and 42 of the second and first tabs respectively of inner closure panel 32. Thus the front portion of detchable tab 70 remains locked in position under inner closure panel second tab 50 and shoulders 58 to secure the top of the carton.
Thereafter the carton may be opened and closed on numerous occasions, and always the locking arrangement is available for reclosure of the carton.
