GABLE TOP CONTAINER Filed May 25, 1964 2 Sheets-Sheet 2 INVENTOR. ISAAC L. WILGOX ATTORNEY.
3,204,850 GABLE TOP CONTAINER Isaac L. Wilcox, Fulton, N.Y., assignor, by mesne assignments, to Phiiiips Petroleum Company, a corporation of Delaware Filed May 25, 1964, Ser. No. 369,828 4 Claims. (Cl. 229-17) This invention has to do with a gable top container formed of paperboard or the like and coated with thermoplastic material to make the container liquid-proof. The container is particularly suited for the packaging of liquid food products, such as milk.
The invention has an object a gable top container wherein the ridge panel surmounting one of the roof panels is readily separable from the contiguous ridge panels sunnounting the end closure panels, and the separation of said contiguous ridge panels from the ridge formation to permit said front roof panel to be moved outwardly to form a pouring spout for dispensing the contents from the container.
The invention has as a further object a gable top closure structure wherein the edge surface of the expanded pouring spout, over which the contents of the container is poured, is in sterile condition when the con tainer is opened.
The invention consists in the novel features and in the combinations and constructions hereinafter set forth .and claimed.
In describing this invention, reference is had to the accompanying drawings in which like characters designate corresponding part in all the views.
In the drawings:
FIGURE 1 is a perspective view of a container embodying my invention.
FIGURE 2 is a plan view of the blank from which the container is formed.
FIGURE 3 is an enlarged sectional view taken on line 33, FIGURE 1.
FIGURE 4 is a perspective view of the container showing the top closure panels partially folded toward closed position.
FIGURE 5 is a perspective view of the container top with the tape removed and the ridge panels of the pouring spout separated and detached from the remainder of the ridge structure.
FIGURE 6 is a perspective View of the top portion of the container showing the pouring spout in expanded form.
Referring to FIGURE 2, the blank is formed with vertically extending score lines 10, 11, 12, and 13. These score lines are intersected by a horizontally disposed score line 14 spaced downwardly from the top edge of the blank a substantial distance, and a second horizontally extending score line 15 spaced downwardly a short distance from the top edge of the blank.
The vertically extending score lines 10, 11, 12, 13 and horizontally extending score line 14, define side wall panels 16, 17, 18, .19 and 20. The panels 17 and 19 are referred to as end wall panels, the panel 18 a front wall panel, and the panels 16 and 20, in the formed container, have their free edges over-lapped and bonded together to form a side wall seam, and these joined panels form the rear wall panel of the container.
The area above the front wall panel 18 is formed with converging score lines 21, 22, extending upwardly from the intersection of the score lines 11, 12, with the score line 14, and merging at the top edge of the blank. There is a vertically extending score line 23 positioned medial of the score lines 11, 12, and extending upwardly from the score line 14 to the intersection of scores 21, 22.
United States Patent 0 3,Z4,85d Patented Sept. 7, 1965 ice These score lines 21, 22, 23, define four triangular areas 25, 26, 27 and 28, these areas constituting the front roof panel which is surmounted by a ridge panel 30, provided by the horizontally extending score line 15.
The score line 14 defines rectangular areas 31, 32, above the panels 16 and 20, respectively. These areas, in the formed container, constitute the rear roof closure panel. The score line defines section 33, 34, which, in the formed container, constitutes a ridge panel surrnounting the rear roof panel, as will be apparent.
The area above the end wall panel 19, as defined by the score line 14 and the upper portions of the score lines 12, 13, is also provided with converging score lines 37, 38, the upper ends of which intersect on the core line 15 medial of the score lines 12 and 13. There is a short score line extending upwardly from the intersection of the score lines 37, 38, to the upper edge of the blank. The score lines 12, 13, 14, 15, 37, 38, define triangular shaped areas 43, 44 and 45, which form an end closure panel, which is surmounted by a ridge panel consisting of the sections 47, 48. There is a vertically disposed score line extending upwardly from the score line 37 to the top edge of the blank, and the section 45 is further provided with a score line 51 extending upwardly from the intersection of the score lines 14, 37, in angular relation to the score line 12.
The area of the blank above the end wall panel 17 is scored in a similar manner to that just described. 52, 53, indicate the converging score lines comparable to the .score lines 37, 38. The score line 54 is comparable to the score line 50, and the score line 55 is comparable to the score line 51. Accordingly, the score lines 10, 11, 14, 52, 53, define triangular shaped areas 60, 61, 62, comparable to the areas 43, 44, and 45, and form the opposite end closure panel which i surmounted by a ridge panel consisting of the sections 63, 64, above the score line 15.
The blank is folded on the score lines 10, 11, 12, 13, about a mandrel, and the side wall seam made to secure together the free edges of the panels 16, 20. A suit-able bottom closure 67 is bonded to the tubular formation. A strip of sheet material is positioned on the top edge of the ridge panel 30 surmounting the front roof panel. This strip is folded to provide an outer portion 70 overlying the outer su-rflace of the ridge panel 30. The lower edge of the outer portion 70 terminates in upward spaced relation from the lower edge of the ridge panel 30that is, from the score line 15.
The inner portion 71 of the strip, overlying the inner surface of the ridge panel 30, extends downwardly a distance below the score line 15, see FIGURES 3 and 4. The inner surface of the strip, contacting the inner .and outer surfaces of the ridge panel 30, is non-sealable thereto. For example, the strip may be formed of aluminum foil, and the surface of the foil strip contacting the ridge panel 30 may be provided with a release coating to prevent the strip from heat scaling to the ridge panel 30.
The foil strip may be initially positioned on the ridge panel 30 of the blank shown in FIGURE 2 prior to converting the blank into the tubular container form, or the foil strip may be applied to the ridge panel 30 after the container is formed, and before the end closure panels are infolded to closed position.
The opposite side of the strip is heat sealable to the contiguous ridge panel sections 48, 64. This scaling is effected and the ridge panels 33, 34, are sealed to the ridge panels 47, 48, 64, 63, by the application of heat and pressure. The thermoplastic coating on the inner and outer surfaces of the container serving to make this permanent adhesive bond. The completed closed and sealed container is illustrated in FIGURE 1.
Preferably, the seal barrier strip terminates in spaced relation to the ends of the panel 30. This permits a small area, as indicated at 80, FIGURE 3, between the contacting surfaces of the ridge panel 30 and the contiguous ridge panels 64, 48, to be permanently bonded together. However, it will be understood that the remainder of the inner surface of the ridge panel 30 is not bonded to those contiguous ridge panels surmounting the end closure panels.
After the container is closed and sealed, a strip of tape 85 is positioned over the outer portion 70 of the seal barrier strip and is sealed thereto, and also to the area of the ridge panel 30 exposed below the lower edge of the outer portion 70 of the strip, and to the exposed end portions 87 of the outer surface of the ridge panel 30. The tape 85 is of somewhat greater length than the ridge panel 30, so that there are free finger grip portions 89 extending beyond the ends of the ridge, as illustrated in FIGURE 1 of the drawings. These tabs 89 serve for the convenient grasping of the tape so that it may be peeled from the container. Inasmuch as the tape is sealed to the outer portion 70 of the seal barrier strip, that outer portion 70 becomes severed from the strip, as illustrated in FIGURE 3 of the drawings. Also, as the tape is peeled from the container ridge, it removes the outer layer of fibers from the outer surface of the ridge panel 30. Because the end portions 87 of the ridge panel 1 are not overlaid by the seal barrier strip, the tape becomes permanently heat sealed thereto, with the result that when the tape is peeled from the container, the outer layer of fibers throughout the entire height of the areas 87 are removed, and this removal is continuous along underneath the outer portion 70 of the seal barrier strip which, of course, is adhered to and removed with the tape.
Due to the fact that the inner portion 71 of the seal barrier strip is not sealed to the inner surface of the ridge panel 30, the ridge panel is free upon removal of the tape together with the outer portion 70 of the strip. However, the inner portion 71 of the strip is heat sealed to the contiguous ridge panels 48, 64, and remains attached to those panels, see FIGURES 5 and 6.
After the tape and the outer portion 70 of the strip is removed from the container, the side edges of the front roof panel are pressed downwardly and inwardly. This effects a separation of the ridge panels 48, 64, from the ridge panels 47, 63, as shown in FIGURE 5. During this action, the front roof panel, comprising the areas 25, 26, 27, 28, is bowed outwardly. This action is assisted by the score lines 50, 54, which act as hinge pivots between the areas 90, 91, of the ridge panels 48, 64, and the areas thereof extending from the score lines 50, 54, to the score lines 11 and 12.
With the front roof panel bowed outwardly in this manner, as shown in FIGURE 5, only a slight inward pressure is necessary on the side edges of the front panel 4 to move the same to eifect full extension of the pouring spout, as shown in FIGURE 6.
What I claim is:
