Kuchenbeclrer, Neenah, Wis, assignor to American Can Company, New York, N.Y., a corporation of New Jersey Filed Oct. 14, 1960, er. No. 62,647 6 Claims. (Cl. 229-17) The present invention relates to a self-sustaining carton or container of fibrous material or the like for the packaging and dispensing of fiowable products such as liquids and granulated substances and has particular reference to a flat unobstructed top end closure which includes a sealed-in sanitarily protected dispensing spout.
The container is readily made from paperboard preferably coated with polyethylene or other suitable substances to provide for liquid leak-proofness and may be produced from a unitary blank of such material. The top closure of the container preferably comprises integral panels which are interfolded in such a manner as to produce a leak-proof flat top which may be partially opened to uncover and release the dispensing spout for use.
An object of the invention is the provision in a selfsustaining fibre container of a fiat unobstructed top closure which is leak-proof and which is readily opened and which produces rigidity in the container and permits of stacking such containers one on top of the other.
Another object is the provision in such a container of a dispensing spout which is formed from parts of the top closure and which is sealed-in so as to sanitarily protect the pouring surfaces of the spout until released for use by the consumer.
Another object is the provision in such a container of a built-in dispensing spout which can readily be reclosed.
Numerous other objects and advantages of the invention will be apparent as it is better understood from the following description, which, taken in connection with the accompanying drawings, discloses a preferred embodiment thereof.
Referring to the drawings:
FIGURE 1 is a perspective view of a sealed container embodying the instant invention;
FIG. 2 is a sectional view of the top end of the container as taken substantially along a plane indicated by the lines 22 in FIG. 1;
FIG. 3 is a sectional View taken substantially along the lines 33 in FIG. 2;
FIG. 4 is a perspective View of the top end of the container showing the top closure partially opened;
FIG. 5 is a perspective View similar to FIG. 4, showing the top closure fully open and the dispensing spout reformed into dispensing position; and
FIG. 6 is a plan view of a unitary blank from which the container and its top and bottom closures are made.
As a preferred and exemplary embodiment of the instant invention the drawings illustrate a substantially rectangular container compris ng a body 11 (FIG. 1), a bottom 12, and a flat top closure 13 made from a single paperboard blank 14 (FIG. 6) of generally rectangular configuration.
The blank 14 (FIG. 6) is suitably cut and scored or creased to divide it into a number of walls, panels and tab portions. Four main side walls 21, 22, 23, 24 are respectively separated from each other and hingedly connected ice together along crease lines 25, 26, 27. A glue flap 28 is hingedly connected along one side edge of wall 24 by a crease line 29.
The bottom 12 for the container may be formed in any suitable manner. By way of example, the drawing of the blank shows four bottom closure flaps 31, 32, 33, 34 respectively connected to the container side walls 21, 22, 23, 24 along crease lines 36, 37, 38, 39. These bottom closure flaps are separated by cut lines 41, 42, 43, 44.
The top end closure 13 for the container comprises a pair of substantially rectangular outer panels 46, 47 hingedly connected to the respective side Walls 21, 23, along respective hinge crease lines 43, 49, a pair of trapezoidal shaped inner panels 51, 52 hingedly connected to the respective side walls 22, 24 along respective hinge crease lines 53, 54 and two pairs of triangular shaped wing panels 55' hin edly connected to the trapezoidal shaped inner panels 51, 52 along hinge crease lines 56, 57, 58, 59 and also hingedly connected to the outer panels 46, 47 and the glue flap 28 along respective hinge crease lines 61, 62, 63, 64. Each of the panels, i.e., the outer panels 46, 47, the inner panels 51, S2, and the wing panels 55 are provided with respective end seam tabs 66, 67, 63, 69, 719 which are connected to the respective panels but which are separated from each other by cut lines 71.
In order to produce the container Ii (FIG. 1) from such a blank 14, the blank is first folded along the side wall crease lines 25, 26, 27, 28, to form the rectangular body, the four side walls being tied together by the glue fiap 28 which is bonded by a suitable adhesive to the inner face of the side wall 21 along its free edge. The four bottom flaps 31, 32, 33, 34 and the adjacent portion of the glue flap 2% are then folded in the usual manner into overlapping position perpendicular to the side Walls, along their respective crease lines 36, 37, 38, 39 and are adhesively secured together to form the bottom 12 of the container. This is a conventional bottom construction.
In this open top end condition with the panels 46, 47, 51, 52, 55 standing upright, the resulting container is ready for filling. After filling the filled container is closed and sealed by pressing the top closure panels inwardly. The inner closure tabs 68, 6? are first bent outwardly into a position fiat against the trapezoidal shaped inner closure panels 51, 52 but are not secured to the panels. The inner panels 51, 52 are then pressed inwardly into a horizontal position over the open end of the container so that both panels are substantially in the same plane. This action folds the triangular wing panels 55 along their hinge crease lines 56, 5'7, 58, 59 and simultaneously draws the outer panels 46, 47 downwardly and inwardly with the result that the triangular wing panels assume a horizontal position flat against and in face-to-face engagement with the inner closure panels 51, 52 in a plane parallel to and contiguous to the plane of the inner panels, the tabs of the triangular panels taking an overlapping position relative to each other in the wing plane and in overlapping relation to the tabs 68, 69 of the inner closure panels as shown in FIGS. 2 and 3.
in a similar manner, the outer closure panels 46, 47 assume a horizontal position flat against and in face-toface engagement with the triangular wing panels 55 in a plane parallel to and overlappingly contiguous to the plane of the wing panels, the tabs 66, 67 of the outer panels taking an overlapping position relative to each other in 3 the outer panel plane and in overlapping relation to the wing tabs 79 as shown in FIGS. 2 and 3.
In this overlapping relation of the tabs as, 67, 53, as, 7s they are bonded together with a suit-able adhesive to produce a permanently secured together fiat lap side seam 73 (FIGS. 1, 2 and 3) which extends transversely of the inner closure panels 51, 52 and completely across the top of the closure to seal the container as shown in PEG. 1. In such an end seam, the tabs of the various panels are distributed in the various planes of the panels and there by results in a flat unobstructed top for the container so that like containers may be readily stacked one on top of the other. With the inner panel tabs 68, a? secured in place under and forming a part of the end seam, leakage of the container contents along the inner edges or" the inner panels is completely eliminated.
The built-in pouring spout herein referred to includes the inner panel 51, its adjacently disposed wing panels 55 and adjacent portions of the out I panels as, 47.
In order to open the container and release the pouring spout for use, it is merely necessary to tear open the end of the seam 73 adjacent the inner panel 51 as shown in FIG. 4. To facilitate tms tearing action, the tab 63 of the inner panel 51 (see FIG. 6), the two tabs to of the two adjacent triangular wing panels 55, and the adjacent portions of the tabs 66, 67, of the outer panels 46, 4-7 are all connected to their respective panels by a scored line or line of Weakness 75 (FIG. 6). In the finished closure, the portions of this line of weakness 75 in the wing panels 55 and the outer panels 46, 47 are disposed one above the other in the planes of the panels and in coincidence with each other along the two outer edges of the tab 63. These coincidental and spaced apart portions of the line of weakness 75, together with the portion extending across the tab 68, provide a ready means for tearing the end seam 73 endwise, transversely of the inner panel 51 and along the wing panels 55 to sever these panels 5d, 55 and the adjacent portions of the outer panels 46, 47 from their tabs 66, 67, 6S, 7% thus leaving the tabs secured together in the end seam 75.
The end seam 73 is torn back to a position just beyond the inner edge of the inner panel 51 as shown in FlG. 4, leaving the remainder of the end seam undisturbed and still intact. With this portion of the seam torn open, the wing panels 55 and the adjacent portions of outer panels 5, 47 may be raised and hinged back against the outer panels. This hinging action is facilitated by a crease line 7r: in each of the outer panels 45, 47, the crease line being located in the panels in substantial coincidence with the hinge crease lines 56, 57 of the wing panels 55. The hinging action of the wing panels 55 fully uncovers the inner panel 51 and in effect causes the inner panel 51 to snap up out of its horizontal position into a spout form- :ing position, which upon release of the wing panels expands into a full open spout as shown in FIG. 5.
Formation of the spout is facilitated by crease lines in the outer panels 46, 47, the inner panel 51 and the container side wall 22. In the outer panels 46, 47 an angularly disposed crease line 77 extending from the terminal ends of the line of weakness '75 to the outer corners of the top closure as shown in FIG. 1 is provided to facilitate upward flexing of the outer panels. In a similar mannor a crease line 78 in the middle of the side :wall 22 and extending up into and across the inner panel 51 provides for flexing of the side Wall and the inner panel to produce a long trough-like or sloping spout formation. The lower end of the crease line 78 merges with a pair of diverging crease lines 7 9 to assist in the flexing of the side wall 22.
After a dispensing operation the spout may be folded back into its original position as shown in FIG. 4 and the partially torn off end seam 73 pressed down over the spout to temporarily reclose the container.
This fiat construction of the top closure imparts considerable rigidity to the upper portion of the container A as a whole so that when the spout is fully open as in dispensing position, the flexing of the body side wall 22 includes this wall as a portion of the spout and changes the body from a rectangular shape to a generally trapezoidal shape and thereby provides for better gripping of the container during dispensing operation. With this increased holding feature it has been found that the usual tendency of the container to slip out of the users hand is practically eliminated.
it is thought that the invention and many of its attendant advantages will be understood from the foregoing description, and it will be apparent that various changes may be made in the form, construction and arrangement of the parts without departing from the spirit and scope of e invention or sacrificing all of its material advantages, the form hereinbefore described being merely a preferred embodiment thereof.
