(Cl. 229-51) have end closing ?aps 3-4, at their opposite ends, said ?aps being cut from each other but are scoredly attached to their associate panels. its principal features the provision of a sift proof ' In Fig. 3, the panels 5, 1, 8 and 6 have major carton, shippable in knock-down condition to and minor end ?aps 4, 4, 4, and 4 defined by a the user, erectable into glue sealed closure and common score line 0, and at ‘their opposite ends ' reclosable, after opening, with a tuck flap closure. have major and minor end closing flaps 3, 3, 3 The present invention relates to an improve ment in reclosable cartons, made of a single blank, from paper board or the like, and has for A further feature of advantages lies in the and 3 de?ned therefrom by a common score . provision of means whereby the reclosing cover line I. Panel 6, Fig. 3, at its opposite ?ap ends, has 10 is created from one side or body forming panel the transverse score line junctions at e and f as will hereinafter be described in detail. A further feature lies in the provision of means perforated as at A-A, from the longitudinal whereby the carton, when glued and erected is score line a, to the longitudinal score line b, as provided. with permanent and temporary seals, I viewed in Fig. 3. Tuck ?ap 2, when the carton is printed, this the temporary seals being readily broken, to provide an access into the carton, and which being on the obverse side of the blank as viewed temporary sealing portions are thereafter used in Fig. 3, and as shown in Fig. 2, is provided ‘to reclose the carton. ' The foregoing, and other features of advan tage will be apprehended as the herein descrip tion proceeds and it will be obvious that modi ?cations may be made herein, without depart ing from the spirit hereof or the scope of the appended claims. with a printed on glue resist, generally denoted ~ by the shading H, leaving a row of uncovered glue spots 9, in which the surface of the paper board is left free to accept glue to form a tem porary seal between the glue resist surface ll of tuck flap 2 and the inner face, Fig. 2, of side forming panel 5, which has a stripe of glue G on its inside face Fig. 2, and as shown by the dotted shading and as shown shaded at G, Fig. 3. This stripe G when the carton is glue sealed, 20 In the drawings, Fig. 1 is a perspective view of the carton, in erected form; Fig. 2 is a perspective view of the carton, as registers with the row of glue spots 9. ' When the carton blank is printed and is ready it appears opened; Fig. 3 is a reduced view of the carton blank; to be glued, the stripetof glue, Fig. 3, is placed 30 30 Fig. 4 is a perspective view of a modified form ' thereon, and the carton panels 2 and 6 are overfolded on score line b, bringing the tuck flap of carton; 2 over to rest upon panel 1, then the panel 5 Fig. 5 is a perspective view of a further modi is overfolded on its score line d, Fig. 3, and the fied form of carton; glue stripe brought up and over to register with 35 Fig. 6 is a perspective view of a carton, modi the glue spots‘ 9' on tuck ?ap 2, and as the glue ?ed over those shown in the preceding ?gures; Fig. '7 is a blank layout of the carton of Fig. sets, these are joined together in a temporary seal, for purposes later ‘to be described. As thus 5; and Fig. 8 is a fragmentary portion of the blank described, the tuck ?ap 2, becomes a temporary glue‘ lap. of Fig. 6. 40 As thus made, the carton is ?at, being folded As in Figs. 3, 7 and. 8 the blank comprises top and bottom body forming panels 8 and 1, side on score lines 12 and d, and is ready to be shipped forming panels 8 and 5 and a tuck flap 2, the to the user to be erected, to be filled with mer latter being de?ned from top panel 6 by a score chandise and ?nally sealed. This final sealing line a, top panel 6, Fig. 3, being defined from side is accomplished, as in Fig. 3, by glueing the ex panel 8 by a score line b, panel 9 in turn being posed surfaces of the end closing ?aps 4-—4 and 3-—3 of panels 6 and ‘I, as indicated by shading de?ned from bottom panel ‘I by a score line 0 and bottom panel ‘I being de?ned from side Then the minor flaps 4-4 and 3-3 of side panel 5 by score line 11. Side panel 5, Figs. 1, 2, 3, 5, 6 and '7 has a forming panels 5 and 8 are intur'ned, and the 50 ?nger out out 5, whereby when the carton is in glued flaps 4-3 of bottom panel 1 are inturned erect form as in Fig. 1, the cover panel 6 and to become attached to the end ?aps 4—4 and'3;—.3 the tuck flap 2 may be grasped by the ?ngers of side panels 5 and 8, then the glued end ?aps is $1 thereon. to open the cover. 55 All of the body forming panels 5, ‘I, 8 and 6, _ ' 4—3 of cover panel 6 are overfolded on to the end ?aps 4-—3 of bottom panel ‘I, and thus the 2,114,134 end closing flaps are all secured to permanently seal the ends of the carton. As thus erected and sealed, the carton has a permanent end seal, a temporary cover tuck flap seal and a cover panel-weakened connection on its opposite ends to its adjacent outer end clos ing flaps 4—-3. To open the carton, a knife blade, or similar member is entered into the crack between the 10 outside face of the inwardly disposed tuck flap 2 forming element having a means for forming a temporary glue lap which is convertible into a. carton reclosing tuck ?ap. . Having thus described the invention what is claimed is; _ 1. A carton formed of a blank of paper board comprising bottom and top panel members hav ing coacting front and rear side members, op posite ends consisting of ?aps which extend from weakened lines of weakened resistance A—-A are broken and the tuck flap and cover 6 grasped together and the front member having at the top 16 thereof a ?nger space, said front member having by the ?ngers by reason of the cut-out l, as as lines of weakened tear resistance, a single wall forming element convertible into a cover and the inside glue resist face of panel 5, and by running the knife blade along the seam be tween edges a and I 2, the glue seals of the spots a are broken from glue stripe G, then the two and the cover 5 is opened as in Fig. 2, the rear score line b acting as a hinge therefor. 20 herein, but all of the modi?cations are directed to structures having features in common, such When desired, the cover 6 may be reclosed, by tucking tuck flap 2 back into its original posi tion in the carton. The cartons of Figs. 4 to 6 inclusive are made up of substantially similar construction as the carton of Figs. 1 and 2. In the Figs. 4 to 8 in elusive, like indices are used to indicate parts of similar or like nature in Figs. 1 to 3. The difference of the carton structure of Fig. 4 over Figs. 1 and 2 lies in the outside lapping and 30 gluing of the sealing tuck ?ap 2, using spaced glue spotting G, to seal the flap 2 to the outer face of panel 5. The temporary seal spotting G may be accomplished as described for Fig. 3, or the glue spots G may be printed on directly. 35 A further difference in the carton of Fig. 4 over the carton of Fig. 1 is that the lines of weak ened resistance A—A of Fig. l have been altered _ on Fig. 4, and, as in said Fig. 4 and Fig. 8, the cover panel 6 has the lines of weakening C—C arranged to converge, across the surface of panel 6 starting at the opposite, outer ends of the tuck panel 2, at its score line a, curving slightly in ward, and then passing backwardly in two con verging straight lines of perforation C--C and 45 ending at the cover score line b. As thus shown in Fig. 4, a knife, or similar edge is passed up under edge g of flap 2, and the spotted, temporary seal G broken, then the cover panel 6 is broken at its lines of weakened con 50 nection C—C and opened on its hinge score I), leaving two end reinforcing panel ?aps E-E on opposite ends of the carton. Fig. 6 combines the feature ofthe modi?ed lines of weakened resistance C—C of Fig. 4 with 55 the feature of the tuck ?ap 2 being temporarily sealed inside of panel 5 as in Fig. 1. Fig. 5 has all of the structural features of Figs. 1, 2 and 6, with the exception that the cover panel 6 has converging lines of weakened tear 60 resistance B—-B, similar to C—C of Fig. 4, but these lines B-B terminate short of the rear score line b, and are intersected by a hinge score line D, all disclosed in the blank layout of Fig. 7. As thus shown, when the inside tuck ?ap Z is 65 released and the lines B—B broken, the cover panel 6 is lifted, as indicated by the dot-dash lines of Fig. 5 leaving reinforcing portions E--E on both ends of the carton, which merge into and join the rear reinforcing portion F, Fig. 4, thus 70 leaving the side and rear wall portions 3—6 and 8 well supported. It will thus be observed that while the single piece blanks of all of these cartons are quite similar, and the functions are the same, some 76 structural features vary in the modi?cations said members, said ?aps being permanently glued on inner face a glue strip, and a tuck lap extend ing from the front edge portion of the top panel and having on one face thereof spaced glue re ceiving spots, said lap being innermost and the 20 spots being engaged with the glue to form a seal, said top panel having therein weakened lines which extend backwardly from the ends of said front edge portion, said lines forming end bound aries of a closure, whereby said faces may be 25 readily urged apart to break the seal, so that said lap and the top panel may be manually grasped at the finger space whereby to open the closure, the structure being then also broken on said weakened lines. 30 2. A carton formed of a blank of paper board which is cut and scored to provide bottom, and top panel members having coacting front and rear side members, opposed ends consisting of ?aps which extend from said members, said ?aps 35 being adhesively attached together and the front member having at the top thereof a ?nger space. said front member having on its inner face aglue strip, and a tuck lap extending from the front margin of the top panel and having on the 40 outer face thereof glue receiving spots, there being glue resisting material on the other por tions of said latter face, said lap being inner most and the spots being engaged against the strip to form a seal, said top member having therein two weakened lines which extend rear ward from the ends of said margin, there being a hinge line connecting the rear ends of the ?rst line, said lines being boundaries of a closure, whereby said faces may be urged apart to readily 50 break the seal, so that said lap and the top mem ber may be grasped at the ?nger space whereby to open the closure, the structure being then also broken on said weakened lines. 3. A carton according to- claim 1, wherein the weakened lines are inclined inwardly from their front ends and are spaced from the ends of the carton, there being portions of the top panel between the last mentioned ends and the ends of the closure, said top panel portions being 00 adapted to form ?nger supports while the closure is being opened. 4. A carton according to claim 2, wherein the closure member is reclosable, the tuck lap beingv again engageable inside of the front side. . 5. A paperboard carton comprising bottom and top panel members having coacting front and rear side members, opposed ‘ends consisting of ?aps which extend from said members, said ?aps being attached together at the respective ends, 70 said front member having at the top thereof a ?nger space, said front member having on its inner face a glue strip, and a tuck lap extending from the front margin of the top member and having on the outer face thereof glue receiving 2,114,184 3 spots, there being glue resisting material around said spots, said lap being innermost and the spots end members cooperating with the ?rst end mem being adhesively engaged on the strip to form a means detachably sealing said front wall and bers, a closure ?ap extending from said rear wall and having a tuck lap on its front part, and seal, said top panel having therein weakened ‘ said lap, said means including on the inner face lines which extend inwardly and backwardly from of said front wall and below its top portion a glue the ends of said margin, there being a hinge strip which extends to the opposite ends, and line connecting the rear ends of the ?rst lines, glue receiving spots on the front face of said lap, said lines de?ning a closure and there being 'a said spots being in registry with said strip and top area outside of said lines, whereby said faces ‘ there being glue resisting material on the face 10 may be urged apart to readily break the seal, of said lap so as to provide said spots. ‘ so that said lap and the top member may be 9. A carton made from one piece of paper grasped at the ?nger space with one hand of a board comprising a bottom and opposed front user to open the closure, the top panel being and rear folds, ?aps carried by the ends of said then also broken on said weakened lines, said folds and bottom and adhesively attached to 15 15 area forming a support for the other hand of form opposite permanent ends of the carton, said the user. permanent ends and the opposed folds having 6. A carton formed from a blank of paper their top parts disposed on the same horizontal board comprising opposed top and bottom pan plane; a top fold and closure having a back hinge els and opposed front and rear panels each of line, said closure having a front tuck ?ap; a tem 20 panels has inwardly closed end ?aps form porary seal consisting of a glue strip extending _20 which ing permanent end walls, certain of said flaps along the front fold below its top edge, said having adhesive material thereon; the top panel tuck ?ap having on its longitudinal medial por having extending completely along its front edge portion a tuck lap which is engageable against the inner face of the front panel; said top panel having therein forwardly of its rear margin a hinge line, and there being inclined severed lines extending through said top panel from the ends of said front edge portion to the ends of said 30 hinge line whereby to form a reclosable cover, said rear margin and the end portions of said top panel outside of the severed lines forming carton reinforcements.
