Abstract
Abstract The drawings illustrate two embodiments of a plastic coated, liquid carrying gable top container, and a blank for forming same, including an easily opened pouring spout by virtue of a slit being formed therein, and a flap integrally formed thereon for protecting the lip of the pouring spout and serving to permit liquid tight sealing of the filled container. In one embodiment, the pouring spout is in the conventional location at one of the folded-in gable end sections. In the other embodiment, the pouring spout is formed as one of the sides of the gable top.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
180 words
A plastic coated paperboard blank for a container, said blank comprising four bottom closure panels, four side panels, a pair of lower top closure panels connected to alternate said side panels, a pair of upper top closure panels terminating in aligned edges connected to said lower top closure panels, a pair of substantially triangular gable panels connected to the other alternate said side panels, a pair of substantially triangular fold-back panels flanking each of said gable panels, a pair of infold lips terminating substantially along said aligned edges connected to each of said pair of fold-back panels, a flap connected to a selected one of the four panels consisting of said pair of upper closure panels and said pair of panels each bearing a pair of infold lips, and a lateral slit formed across said selected one of the four panels for a distance beneath said flap less than the full width of said flap, and said flap having a height extending outward from said aligned edges sufficient for the flap to cover said lateral slit when folded down thereon.
Claim 2
Dependent Claim
180 words
A plastic coated paperboard blank for a container, said blank comprising four bottom closure panels, four side panels, a pair of lower top closure panels connected to alternate said side panels, a pair of upper top closure panels terminating in aligned edges connected to said lower top closure panels, a pair of substantially triangular gable panels connected to the other alternate said side panels, a pair of substantially triangular fold-back panels flanking each of said gable panels, a pair of infold lips terminating substantially along said aligned edges connected to each of said pair of fold-back panels, a flap connected to a selected one of the four panels consisting of said pair of upper closure panels and said pair of panels each bearing a pair of infold lips, and a lateral slit formed across said selected one of the four panels for a distance beneath said flap less than the full width of said flap, and said flap having a height extending outward from said aligned edges sufficient for the flap to cover said lateral slit when folded down thereon.
Claim 3
Dependent Claim
25 words
The blank described in claim 1, wherein said flap and said slit are formed in conjunction with one of said two pairs of infold lips.
Claim 4
Dependent Claim
43 words
The blank described in claim 1, wherein said flap and said slit are formed in conjunction with one of said pair of upper closure panels, and a vertical score line is formed across the centerline of said upper closure panel and said flap.
Claim 5
Dependent Claim
27 words
The blank described in claim 2, wherein said one of said two pairs of infold lips is the pair positioned between said pair of upper closure panels.
Claim 6
Dependent Claim
26 words
The blank described in claim 3, wherein said one of said pair of upper closure panels is the one between said two pairs of infold lips.
Claim 7
Dependent Claim
49 words
The blank described in claim 2, and a score line formed to extend downwardly from each end of said slit across the lower portion of one of said two pairs of infold lips and across said adjacent pair of fold-back panels to the base of said flanked gable panel.
Claim 8
Dependent Claim
36 words
The blank described in claim 3, wherein said lower closure panel adjacent said one of said pair of upper closure panels is formed to include an intermediate triangular fold-out panel flanked by two triangular fold-out panels.
Claim 9
Dependent Claim
51 words
The blank described in claim 7, and a score line formed to extend downwardly from each end of said slit across the lower portion of said one of said pair of upper closure panels and across said two triangular fold-out panels to the base of said flanked intermediate triangular fold-out panel.
Claim 10
Dependent Claim
147 words
A gable top, liquid carrying container including four side panels, a bottom closure arrangement connected to the lower ends of said side panels, and gable top closure panel sections connected to the upper ends of said respective side panels, said gable top closure arrangement comprising means formed on one of said gable top closure panel sections for providing a pouring spout, said means including a slit formed for a distance across an upper portion of said one of said panel sections less than the full width thereof, and a flap formed on the upper edge of said one of said panel sections and folded over said slit and sealed directly onto said one of said panel sections for preventing leakage through said slit until said flap is raised and said pouring spout is opened to permit pouring of a liquid over the lower edge of said slit.
Claim 11
Dependent Claim
147 words
A gable top, liquid carrying container including four side panels, a bottom closure arrangement connected to the lower ends of said side panels, and gable top closure panel sections connected to the upper ends of said respective side panels, said gable top closure arrangement comprising means formed on one of said gable top closure panel sections for providing a pouring spout, said means including a slit formed for a distance across an upper portion of said one of said panel sections less than the full width thereof, and a flap formed on the upper edge of said one of said panel sections and folded over said slit and sealed directly onto said one of said panel sections for preventing leakage through said slit until said flap is raised and said pouring spout is opened to permit pouring of a liquid over the lower edge of said slit.
Claim 12
Dependent Claim
123 words
The gable top, liquid carrying container described in claim 9, wherein said one of said panel sections includes a substantially triangular gable panel, a pair of substantially triangular fold-back panels flanking said gable panel, and a pair of infold lips connected to said pair of fold-back panels as extensions thereof, said flap being connected to said pair of infold lips as a folded-over extension thereof, and said slit being formed laterally across a predetermined portion of said infold lips and adapted to be covered by said flap when said gable top closure panel sections are in the closed mode and to serve as the edge of said pouring spout when said gable top closure panel sections are opened and said flap is raised.
Claim 13

The gable top, liquid carrying container described in claim 9, wherein said one of said panel sections includes a lower closure panel formed to include an intermediate triangular fold-out panel flanked by two triangular fold-out panels, and an upper closure panel, said slit being formed laterally across a portion of said upper closure panel and said flap being connected as a folded-over extension of said upper closure panel, and a vertical score line formed across said upper closure panel and said flap for cooperation with said fold-out panels when said one of said panel sections is opened into a pouring spout, said lower edge of said slit serving as the edge of said pouring spout.
Claim 14
Dependent Claim
53 words
The gable top, liquid carrying container described in claim 10, and a score line formed to extend downwardly from each end of said slit across the lower portion of one of said two pair of infold lips and across said adjacent pair of fold-back panels to the base of said flanked gable panel.
Claim 15
Dependent Claim
55 words
The gable top, liquid carrying container described in claim 11, and a score line formed to extend downwardly from each end of said slit across the lower portion of said one of said pair of upper closure panels and across said two triangular fold-out panels to the base of said flanked intermediate triangular fold-out panel.
