PREFERRED EMBODIMENT A novel pouch-carton l0 constructed in accordance with this invention is best shown in FIGS. 1, 2. The pouch-carton 10 comprises a generally flat tubular product pouch or bag 12 which is surrounded or enclosed by a generally flat paperboard protective enclosure or carton 14. The pouch 12 is of conventional design and construction being composed of lightweight non-self-supporting flexible material which is impervious to fluids. Briefly, the pouch may consist of two coextensive rectangular side sheets or side panels l5, 15 disposed in relatively closely spaced face-to-face relation, the side sheets being suitably joined together along corresponding margins and having at least the top margin thereof defining an opening end portion or section. The top margin being joined together by a seal 16 to form the generally flat closed product pouch.
As shown in FIGS. 1 and 2, the carton or container 14 includes a generally rectangular parallelopipedon shaped body member 25, a removable end or bottom wall 26 and a top or upward tear-off portion 27. The body member 25 includes main front and back panels or walls 20, 21 connected at lower side edges 16 to secondary side panels or walls 30, 31.
The carton 14 may best be described in detail by viewing the carton blank 13 as illustrated in FIG. 3. As can be seen, the carton blank 13 comprises two similar multi-paneled rectangular sheets 23, 24 interconnected by intermediate side panel 30 along inward side edges 16 and having opposite attachment flaps 28, 29 projecting outwardly at side edges 16. Attachment flaps 28, 29 overlap in the erected carton to form side wall 31. Each sheet 23, 24 is defined along side or lateral edges by interrupted longitudinal lines 16. Each sheet 23, 24 is defined at upper ends by transverse lines 50, 50, severance lines 40, 40, and at lower ends by separation lines 35, 35 and transverse lines 51, 51. Sheets 23, 24 include lower folding extension panels 33, 34, main rectangular body panels 20, 21 and upper extension panels or flaps 38, 39. Lower extension panels 33, 34 are separated from panels 20, 21 by transverse separation or tear lines 35, 35. Any desired configuration can be used for these tear lines in order to provide a zone along which the bottom wall 26 can be torn. Spaced slits, perforations, spaced hook-shaped slits or any other form of weakened areas are suitable tear line configurations. In the illustrated form, each separation line 35 is shown as comprising a series of hook-shaped slits cut into the sheets 23, 24. In each instance, the hooks or slits extend through the sheets 23, 24. A starting notch 36 is provided at the lower end of side panel 30 to permit entrance of a finger tip between bottom wall 26 and side panel 30 in the erected condition to initiate tearing of the overlapped extension panels 33, 34.
Vertical longitudinal weakening or fold lines 37 are provided in panels 20, 21 to function as a shaping means to facilitate shaping of a pouring spout and also to permit the forming of a stable support stand. weakening lines 37 extend from the tops of panels 20, 21 at approximately the mid-portion of severance lines 40, 40 down to separation lines 35, 35. The shaping means comprise the upper portions of weakening lines 37; that is, the portions of weakening lines 37 which are adjacent severance lines 40, 40. The upper extension flaps 38, 39 are attached to panels 20, 21 along horizontal severance lines 40, 40. Severance lines 40, 40 comprise a series of discrete collinear cut lines through the sheets 29, 31. Severance lines 40, 40 terminate'short of longitudinal edges 16in vee-shaped tearing notches 49.
In each body panel 20, 21, gripping means are provided for squeezing body member 25 to form the pouring spout. The gripping means comprise opposed pairs of curved recesses 41 disposed downwardly from severance lines 40, 40 and along upper side edges 16. As shown, the gripping means are defined by inwardly projecting arcuate line portions 42 having bisectors which are generally parallel to the severance lines 40, 40.
Separate shaping means for forming the spout are also provided on body panels 20, 21. This shaping means comprise spaced pairs of diverging perforation lines or intermittent score lines 43 in the direction away from severance lines 40, 40. The perforation lines 43 extend between spaced points 60, 60 on severance lines 40, 40 and the arcuate line portions 42 to define generally trapezoidal shaped corner holding portions 44 on the main body walls 20,21.
As noted from FIGS. 1 and 2, in the erected condition lower extension panels 33, 34 are overlaped and secured together to form the removable bottom wall 26 normal to panels 20, 21 and which is defined by the separation lines 35, 35. Also, side panel 28 overlaps and is adhered to side panel 32 to form the side wall 31.
As can be seen best from FIG. 2, the pouch I2 is inserted into the carton with the pouch opening end portion being adjacent and between the flap extensions 38, 39. The flap extensions 38, 39 are then brought together and adhered to the pouch seal area 16 along a thin line of adhesive 63 form the tear off extension 27. The upper portions of panels 20, 21 are also secured to the pouch side sheets along a thin layer of adhesive 64 adjacent severance lines 40, 40 and extending the width of the carton panels 20, 21 intermediate side edges 16. 9
Looking to FIGS. 4 7, the sequence of operations for opening the pouch-carton will now be explained. Since in most instances the pouchcarton will be used to package an individual portion of a liquid such as liquor, the pouch-carton should he held in the upright position when removing the tear-off portion 27. The tear-off portion 27 is grasped by the hand and the severance lines 40, 40 torn from left-to-right starting at the left vee notch 49. The extension 27 is ripped entirely off. In so doing, the severance lines 40, 40 serve as a horizontal tearing edge to sever the pouch below the pouch seal area 16 to permit egress of the packaged fluid. It is advantageous that this tearing line be substantially horizontal to minimize spilling and to permit the maximum amount of product to be packaged therein.
As can best be seen in FIG. 5, the pouch-carton is pinched open to form a pouring spout 70. The opened carton 14 is grasped or gripped at the curved recesses 41 with the thumb along one side of the carton and the middle and index fingers along the other side. Then, an inward traverse pressure is exerted on the panels 20, 21 which causes panels 20, 21 to bulge outwardly along the weakening lines 37 and the perforation lines 43 to form a spout having a rhombusshaped cross section. It is to be noted that the trapezoidal corner holding portions 44 do not bulge outwardly. Since the upper portions of the pouch are secured to the inside surfaces of the panels 20, 21, when these panels bulge outwardly, the pouch side sheets move outwardly also, thus imparting the same rhombus-shaped cross section to the top of the pouch bag.
As shown in FIG. 6, to pour the contents out of the pouch, the carton is grasped and tilted. In this manner, the tops of the bulged body panels function as a spout or funnel to permit a controlled amount of fluid to spill over the severed edges 40, 40.
Though the unopened pouch-carton possesses a degree of vertical stability, the relatively tall and narrow profile will not permit the partially filed pouch-carton to remain upright on a tray or table when exposed to mild disturbances or gy rations. To provide for vertical stability, stand forming means are provided on the carton 14. The stand forming means comprise the lower portions of weakening lines 37; that is, the portions of weakening lines 37 which extend downwardly to bottom wall 26 at the separation lines 35, 35. As can best be seen in FIG. 7, by applying a transverse inward squeeze to the side walls 30, 31, the main panels 20, 21 bulge outwardly along weakening lines 37 to form a stable support stand having a generally rhombohedral shaped configuration. Prior to squeezing side walls 30, 31, bottom wall 26 is removed along lines of separation 35, 35 by grasping the bottom wall 26 near the recess 36 and pulling outwardly on the bottom wall.
After all of the contents of the pouch have been consumed, the, product pouch and carton can be collapsed to be easily disposed of.
