Jan. 30, 1962 E. L. ARNESON CARTON 4 Sheets-Sheet' 4 Filed Jan. 50, 1961 ited States This invention relates to packaging and is more particularly concerned with improvements in a carton of generally rectangular shape which is formed from a single blank of foldable sheet material and which is adapted for lling through an initially open end `which is thereafter permanently closed, and having an adjoining side thereof formed so as to provide a reclosable cover which permits ready opening for removal of the contents and reclosing of the carton for storage, if desired.

In one form of package for certain products, a generally rectangular carton has been employed which has been fabricated from a single blank of paperboard sheet material cut and scored to provide side and end wall panels which are secured together initially' to form a tubular container with the iiaps at one end being open for filling and being subsequently closed, the container in its filled and closed condition having one of the side walls hinged to an adjoining side wall so that it may be swung to an open position to permit dispensing of the contents of the container through the side thereof and the cover thus formed generally having flaps along the free edges thereof which rare disposed in the planes of the front side and end Walls in the closed condition of the carton. This form of carton has been widely adopted for the packaging of certain consumer products. It has been used particularly for the packaging of ice cream, in halfgallon quantities, for sale directly to the consumer as distinguished from bulk packaging in larger quantities for sale to restaurants, soda fountains and the like. While previous cartons of this type have been widely adopted for this purpose, largely because of the ease with which they may be set up and filled on relatively inexpensive machinery, the carton has not been entirely satisfactory from the consumer standpoint. Cartons of this type previously available have been designed with a cover forming one of the largest sides so as to provide the largest possible opening for dispensing the ice cream, which frequently is frozen to a hardness making removal from the carton diiiicult, but the users have generally ignored the side opening reclosable cover feature of the carton and most often opened the carton by tearing out an end resulting in diiculty in removing the contents and frequently yresulting also in the entire carton coming apart, so that satisfactory reclosure of the carton when not all the contents is removed is Virtually impossible. This failure to employ the cover arrangement as intended in opening and reclosing the carton with subsequent Vannoyance and dissatisfaction with the carton on the part of the consumer has been recognized by the ice cream manufacturers and other users of the cartons and various efforts, mostly without success, have been made to instruct the consumer in the proper opening and reclosing of the carton. However, even when the cartons previously in use have been properly opened, the covery arrangements have not been satisfactory because the covers have either been diiiicult to reclose or, when reclosed, have resulted in a sloppy appearance due generally to loose cover ilaps. is to provide an improved carton of the type referred to which is adapted to be used in the sameV manner but having a reclosable cover arrangement which may betvery easily opened by the consumer and readily reclosed so YasV to leave a neat and attractive package for return to storage when only a portion of the product has been disarent An object of the present invention Y pensed therefrom and which also may be set up and filled by the manufacturer with only slight modification of the equipment now commonly used for setting up, tilling and closing the cartons previously available.

Another object of the invention is to provide improvements in a packaging container or carton of the type which is formed from a blank of paperboard or similar material cut and scored so as to provide Wall forming panels which may be connected to form, when initially set up, a tubular container with an open end for receiving a product therein, the open end being then permanently closed and the carton having a side wall in the form of a cover which is initially closed and held by a breakable seal but which may be readily released for hinging movement so as to permit the product to be dispensed through a side of the carton with the cover being reclosable so as to restore the carton to its original condition, except for the breakable seal.

A further object of the invention is to provide an improved rectangular carton of the type described wherein a paperboard blank is cut and scored so as to divide the same into foldable wall forming panels with the front and back Wall panels having end extensions which are foldable into the end Walls where they are overlapped l and secured in such a manner as to provide the carton with a side opening captive telescopic cover or closure.

A more specific object of the invention is to provide a generally rectangular carton which is formed from a single blank of paperboard or similar ilexible material by cutting and creasing the blank so as to divide the same into a series of connected Wall forming panels which permits the carton to be formed or set up initially as a tube with one end closed and the other end open for filling and subsequent closing, the carton, when fully closed, having a body portion and a cover portion, with the body portion comprising a bottom wall, an upstanding side and end walls, and with the cover portion hinged along one edge to a top forming edge of one of the body side walls and having connected side and end wall aps along the other edges Which are disposed in the planes of the corresponding walls of the body portion with the side wall flap of the cover member which is opposite the hinged edge thereof being secured to the adjacent side wall of the body portion by a readily breakable or releasable fastening means so as to permit easy opening of the cover portion for removal of the contents from the carton.

It is a still further object of the invention to provide a paperboard carton of the type described in which the end walls of the body and cover portions have panel sections which are initially integral and adapted to be separated by tearing along a perforation line or other weakened severance line when the cover is rst opened.

These and other objects and advantages of the invention will be apparent from a consideration of the-carton structures which are shown by way of illustration in the accompanying drawings wherein:

Referring tirst to FIGURES 1 to 7 of the drawings, the carton 10 which is illustrated is particularly designed for use in the packaging of a product, such as bulk ice cream, in predetermined quantities, for example, one-half gallons. The use of the carton 10 is, of course, not limited to the packaging of the particular product referred to but it may be used for any other commodity, as desired.

The carton 10 will be best understood by reference to the manner in which it is fabricated. A blank 11 (FIG- URE 2) of generally rectangular form is initially cut from a sheet or web of flexible sheet material, such as paperboard, or the like, which may be treated by applying printing or a coating to the surface depending upon the product which is to be packaged in the carton. When used for ice cream, suitable printing would, of course, be applied to the outside surface and a coating of wax or similar material may be applied to the inside or both surfaces of the sheet material. The material could, of course, be formed of a laminate comprising two or more sheets of like or dilferent character, printed or unprinted, as desired.

The blank 11 is cut and scored to divide the same into a series of wall forming panels. In its final form the cut and scored blank is symmetrical about the longitudinal center line indicated at a-a. The blank 11 is provided with laterally spaced, longitudinally extending score lines 12 and 12 which divide the same into a center section 13 and side sections 14 and 14', the latter extending along the side edges of the blank. The center section 13 of the blank is subdivided by transversely extending, longitudinally spaced score lines 15, 16, 17 and 18 into a front side wall forming panel 20, a bottom wall panel 21, a back side wall panel 22, a top wall or cover panel 23, and a front wall panel or cover ap 24 which are hingedly connected along the score lines in theV order named. The back wall forming panel 22 is further subdivided by a transversely extending hinge forming score line 25 which is parallel with the transverse score line 17 and which forms between these two score lines a back Wall forming panel or section 26 for a cover forming portion of the carton which is fabricated from the portion of the blank extending between the score line 25 and the'end edge 27 of the blank. The score line 25 forms a hinge between the cover forming portion or section of the finished carton and the body forming portion thereof which is fabricated from the portion of the blank extending from the hinge 4 forming score line 25 to the other end edge 28 of the blank.

The two side sections 14 and 14 of the blank 11 are divided into end wall forming panels by cutting lines as shown. The panel elements in the one side section 14 of the blank will be described, it being understood that the other blank section 14 is divided in the same manner into corresponding elements which are indicated by the same numerals primed. The blank section 14 is cut on the parallel transverse lines 30, 31, 32 and 33 which extend outwardly of the longitudinal score line 12 from the ends of the transverse score lines 15, 16, 17 and 18, respectively, to provide the end wall forming panels 34, 35, 36, 37 and 38. The one panel 36 which extends from the back wall forming panel 22 is subdivided by a transverse line having a completely cut through portion 4t) and a perforated or partially cut through portion 41 into two panel sections 42 and 43. The panel 34 which extends from the front side wall forming panel 20 is cut away on the transverse and diagonal lines 44 and 45. The panel 35 which extends from the bottom wall panel 21 forms the main end wall panel of the carton and cooperates with the two adjoining panels 34 and 42 to form the end wall of the body or bottom forming portion of the carton when fully erected. A portion of the blank between the cutting lines 32 and 33 is cut away on the lines 46, 47 and 4S to leave the panel 37 which has a maximum dimension transversely of the blank corresponding to the dimension of the adjoining panel 38 in the longitudinal direction of the blank. The panels 37, 38 and 43 constitute the end wall forming panels of the cover portion of the carton.

The blank 11, when cut and creased `as indicated n FIGURE 2, is provided with adhesive on the panel 24, as indicated, and then folded about the score lines 15 and 17 to bring the end panel 24 into overlapping relation with the marginal portion of the end panel 20 which completes the formation of the carton in flattened or collapsed condition as shown in FIGURE 3.

In using the carton it is first opened up into tubular form as illustrated in FIGURE 4, preferably in a conventional carton erecting or set up machine, and the end wall panels at the one end of the tube are folded into closed position with the panel 35 being iirst folded about the score line 12 into the plane of the end wall, followed by the oppositely disposed panel 37 after which panels 36 and 34 are folded inwardly in that order, followed by infolding of panel 38 so that the panels 34 and 38 have marginal portions overlapping the corresponding portions of the panels 42 and 43, with an adhesive being applied between the two confronting surfaces, as indicated in FIGURE 3, prior to the nal folding. The carton is moved in the upright opened up position with the lowermost end thereof closed to the filling mechanism and the product to be packaged is placed therein through the uppermost open end. Thereafter, the top end panels are closed and sealed in the same manner as described with respect to the lowermost end thereof which completes the setting up, filling and closing of the carton and provides a package, as indicated at 10, in FIGURE l.

When the carton 10 is opened by the product user, the front panel 24 on the cover portion may be readily torn loose from the front wall 20 of the body portion of the carton and the cover portion hinged upwardly about the hinge line 25 with the panels 43 and 43' being torn along the perforation lines 41 and 41 to release the end walls of the cover portion from the bottom end walls for further opening movement of the cover portion. When it is desired to reclose the carton, the cover forming portion may be swung to the closed position about the line 25, the front panel 24 of the cover portion closing on the front panel 20 of the body portion and the end wall panels 37 and 37 on the cover portion nesting in a recess provided by the cut out upper margins of the end wall panels 34 and 42 of the body portion of the carton so that the reclosed carton presents a neat and attractive appearance with no loose or projecting flaps and no tendency to reopen or come apart during storage.

A modied form of carton is illustrated in FIGURES 8 to 10. In this form of the invention, the carton 50 is fabricated from a generally rectangular blank 51 of paperboard or like material which is cut and scored as illustrated in FIGURE 9. The blank 51, when prepared, is symmetrical about the longitudinal center line b--b and only one-half of the blank is illustrated. The blank is divided by longitudinal score lines 52 into a center section 53 and side sections 54. The center section 53 is subdivided by parallel, transversely extending, longitudinally spaced score lines S, 56, 57 and 58 into wall forming panels 60, 61, 62, 63 and 64. The panel 61 is adapted to form the bottom wall, the two adjoining panels 60 and 62 are adapted to form the side walls of the body portion of the carton. The two panels 62 and 64 are adapted to for-m the top Wall and front flap, respectively, of the cover forming portion of the carton, the top wall panel being hinged along the edge thereof `delined by the score line 57 to the back wall forming panel 62 of the carton body portion. The pane-ls in the Section of the blank 51 -which extends from the score line 57 to the one end 65 of the blank are adapted to form the body portion of the carton While the panels in the section of the blank extending from the score line S7 to the end edge 66 of the blank Iare adapted to form the cover portion of the carton.

Each side section 54 of the blank 51 is divided by transverse cutting lines 67, 68, 69 and 70, which extend from the ends of the score lines 55, 56, 57 and 58, respectively, into end wall forming panels or flaps 71, 72, 73, 74 and 75. The panel 72 is of a size corresponding `approximately to the cross sectional area of the carton while the remaining panels are of a considerably smaller dimension in the direction transversely of the blank. The one end Wall panel 71 is cut out on the line 76 at the corner of the blank and the panel 73 is subdivided into two sections 77 and 78 by a partly cut, partly perforated line 7 9.

The blank 51, when cut and scored as illustrated in FIGURE 9, is folded into attened tubular form about the score lines 55 and 57 after an appropriate application of adhesive on the inside face of the panel 64 as indicated at S0. The tubular carton is then opened up and the one end closed in the same manner -as indicated in FIGURES 4 and 5 with the panels 72, 74, 71, 73 and 75 being folded into the plane of the end Wall in the order named. An adhesive is applied to the inside faces of the panels 71, 73 and 75 so that these panels are adhesively connected to the panels 72 and 74 against which they are folded.

When it is desired to open the carton to provide access to the contents, the `front flap 64 of the cover portion isv pulled loose from the front wall 60 of the body portion and the cover portion is hinged upwardly about lthe score line 57 breaking the material loose along the perforation line 79 and freeing the panel section 78 for movement with the cover portion to which it is attached.

A further modification of the carton is illustrated in FIGURES l1 to 14. In this form, the carton 100 is fabricated from a generally rectangular blank 101 which is cut and scored as illustrated in FIGURE l2. The blank 101, when prepared, is symmetrical about the longitudinal center line c-c and only one-half of the blank is illustrated. The blank is divided by longitudinal score lines 102 into a center section 103 and two side -Sections 104. The center section 103 is subdivided by parallel, transversely extending, longitudinally spaced score lines S, 106, 107 and 108 into wall forming panels 110, 111, 112, 113 and 114. The panel 111 is adapted t0 form the bottom wall and the two adjoining panels 110 and 112 are adapted to form the side walls of the body portion of the carton. The two panels113 and 114 are adapted to form the top Wall and front flap, respectively, of the cover forming section of the carton, the top wall panel 113 being hinged along the edge thereof defined by the score line 107 to the back wall forming panel 112 of the carton body portion. The panels in the section of the blank 101 which extends from the score line 107 to the one end 115 of the blank are adapted to form the body portion of the carton While the panels in the section of the blank extending from the score line 107 to the end edge 116 of the blank are adapted to form the cover portion of the carton.

Each side section 104 of the blank 101 is divided by transverse cutting lines 117, 118, 119 and 120, which extend from the ends of the score lines 105, 106, 107 and 108, respectively, into end wall forming panels or flaps 121, 122, 123, 124 and 12S. The panel 122 is of a size corresponding approximately to the cross sectional area of the carton. The one end wall panel 121 is cut out on the line 126 at the corner of the blank and the panel 123 is subdivided into two sections 127 and 128 by a partly cut, partly perforated line 129.

The blank 101, when cut and scored as illustrated in FIGURE l2, is folded into flattened tubular form about the score lines and 107 after an appropriate application of adhesive on the inside face of the panel 114 as indicated at 130. The tubular carton is then opened up and the one end closed in the manner indicated in FIGURE 13 with the panels 122, 124, 121, 125 and 123 being folded into the plane of the end wall in the order named. An adhesive is applied to the inside face of the panel 123 so that this panel is adhered to the inner flaps 122 and 124, at the one end thereof, and to the portions of the panels 121 and 125 which are overlapped thereby When the folding is completed.

When it is desired to open the carton to provide access to the contents, the front flap 114 of the cover portion is pulled loose from the front wall of the body portion and the cover portion is hinged upwardly about the score line 107 breaking the material loose on the perforated portion of the severance line 129 and freeing the panel section 128 for movement with the cover portion to which it is attached. The panel section 127 is adhered to the rear portion of the inside flap 122 so that the latter is held in upright position regardless of the material left in the carton when it is being emptied. When the cover portion is reclosed, the inner end wall ap 124 nests in the recess provided at the top of the panels 121 and 127 and the meeting edges of the outermost panels 127 and 128 extend along the severance line 129 whereby to provide a neat appearing, completely closed end wall.

While the specific materials referred to and the particular details of construction described herewith are employed in the .forms of the carton shown in the drawings, it will be understood that other materials and equivalent details of construction may be resorted to within the spirit of the invention.
