Desmond, Philadelphia, Pa, assignors to Container Corporation of America, Chicago, IlL, a corporation of Delaware Filed Nov. 5, 1963, Ser. No. 321,451 8 Claims. (Cl. 22951) The present invention relates to folding cartons and more particularly to cartons for retention of commodities, such as food, from which a portion of the contents may be removed and the size of the carton may easily be reduced and the carton thereafter effectively secured about the remainder of such contents.

An important object of the invention is to provide a carton which is of particular advantage for packaging frozen foods, such as peas in separable or fluent condition, to enable the user to reduce the carton size con veniently and reclose it after a portion of the contents has been removed.

A further object of the invention is to provide an efficient construction of foldable carton which may be cut from a single blank of paperboard to form a tubular carton with end closures, there being formed fold lines and tear lines in certain of the carton walls, whereby, after removal of a portion of the contents, a sizeable part of the carton may be torn or cut away, leaving usable closure parts by means of which the carton may easily be reclosed and the contents kept secure until such time that it is desired to use the remainder.

A still further object of the invention is to provide a reduceable size carton of tubular construction, having edge walls and somewhat wider side walls, the carton being constructed so that one of the side walls constitutes a closure which may be opened to form a relatively wide opening for reception of the contents and, after such closure is secured, the carton may have its contents dispensed from one of its tubular ends, following which, a portion of the carton is severed or torn away to reduce the carton size, the remaining unsevered parts of the carton serving as an effective closure for securely holding the remaining contents until needed.

A still further object of the invention is to incorporate effective partitioning means within a carton as above described so that one-half or any other desired proportion of the contents may be removed and the carton then reduced in size and reclosed.

Additional and more specific objects and advantages of the present invention will become apparent as the description proceeds.

In the distribution and sale of food products for home consumption, particularly frozen foods, it has been customary for some time to pack products in standard or uniform sized cartons holding approximately ten to twelve ounces. The amount contained in these packagesis in many instances too large for small families and it frequently happens that persons preparing the food will decide to use approximately one-half the contents of the original package and leave the remainder in the carton for later use. In opening the carton to remove the contents, it is frequently torn and the portion of food left for future use is poorly or inadequately enclosed within the original carton. It is desirable, therefore, to provide an original carton of standard size capable of being readily opened for removal of about one-half the usual contents and, thereafter, readily convertible to a neat carton of smaller size which will retain the unused portion of the food for future use.

According to the present invention, a carton is provided that will originally hold the customary quantity of contents and which may easily be opened for removal of half the contents. The carton is originally formed with suitable lines of severance to provide for ready removal of an unneeded part of the carton walls and thus allow the remainder of the carton to be closed in a neat and effective manner toretain the part of the contents which are to be kept packaged for later use.

Referring particularly to the drawings, the carton, indicated as a whole at 1, is formed from relatively thin, foldaole paperboard and may be made from a blank suitably cut and scored to provide a top wall or cover panel 2, bottom panel 3, edge wall panels 4 and 5, and securing flap 6, defined by fold lines 7, 8, 9 and 10 extending transversely of the blank. End closure flaps 12, 13 and 12a, 13a are formed on the ends of the respective panels 2 and 3 and small end closure flaps 14, 15 and 14a, 15a are formed on the ends of the respective panels 4 and 5. These flaps are foldable along score lines 16 and 16a extending lengthwise of the blank.

When the carton is to be set up for filling, the panels 4 and 5 are folded to upright position relative to panel 3, and to the respective flaps 13, 14 and 15; and 13a, 14a and 15a will be folded in overlapping relation. These flaps may be secured together in any desired manner.

' The top panel 2 may be left in the plane of the edge wall 4 until the carton has been filled, after which, panel 2 is folded down over the contents andthe securing flap 6 is folded down to overlap the edge wall 5. For the purpose of attaching the flap 6 to wall 5 the flap may be formed with a locking tongue 17 with projecting portions 17a and 17b arranged to pass through a slit 18 formed in the edge Wall 5. The flap 17 may thus be secured releasably to the edge wall 5.

For the purpose of enabling the carton to be reduced in size after removal of part of the contents, alternate closure parts are formed along laterally extending, severable lines, medially of the length of the carton. Referring to FIGURE 5, a weakened line of tear or severance is formed lengthwise of the blank to provide closure parts from portions of the walls 2, 3, 4 and 5, such closure parts being hinged along a fold line 19 extending lengthwise of the blank. As herein shown, a severance line, formed by a series of short cuts or slits slightly spaced apart, begins at the outer free edge of edge panel 5 and extends diagonally across panel 5, as indicated at 20, to-define a closure, portioncomprising'two shaped gusset'folds Saf and 5b, definedfrom each, other by fold line 50. v

portion 35d, will cling to this portionandbe likewise re- 'moved and discarded. If desired, the panel'portion 57 can be connected to panel portion 35d along a line of severanceinstead of the fold line-57b. In such case, the

partition can be left in place and folded below the newly formed closure parts or'can merely be torn from the a the partition in the propenposition as rigid tab, 34a is the severance line being extended around such tab, portion as indicated at 24.

By deflecting :lhlS'tab slightly inwardly'and inserting the edge of panel 56 between the tab 7 and its panel 34'the panel 56 may be held with sufficient firmness to stay in place during filling of the carton.

These panels are defined from each other by fold lines 6 6, 67, 68 and 69. a

The endsof the carton. may be closed'with end wall closure-panels carrying tuck flaps.
