Abstract

A pour spout for a carton is formed from the carton material in two superimposed panels. The outermost panel has an opening and a tab member, the first end of which is connected to the remainder of the panel at a fold line. The second or opposite end of the tab member is part of the perimeter of the opening. The first and second ends of the tab member are defined by parallel rows of perforations. The inner panel includes a tab member which is aligned with the first tab member. A pair of wing members extend from fold lines at opposite side edges of the inner tab member. The wing members may have an arcuate edge and may include a projection which will limit pivotal movement of the spout formed by the tab members and wing members. The superimposed panels may be overlapping side panels, overlapping top panels, or a combination of side panels and top panels having extensions which overlap the side panels. In one embodiment, a separate insert serves as the innermost panel.

A carton having closeable pour spout formed in one wall, comprising:

an outer panel having an opening therethrough and an outer tab having a first end hingedly connected to the remainder of the outer panel, a second opposite end defining a portion of the perimeter of the opening and side edges connecting the first and second ends of said outer tab;
and
an inner panel superimposed upon and bonded to said outer panel over a part of their facing surfaces, said inner panel including an inner tab forming a spout floor, said inner tab being bonded to said outer tab, said inner tab being hingedly connected along a bottom edge thereof to said inner panel in registry with said outer tab, and first and second integral wing members hingedly connected to opposite side edges of said inner tab, the surfaces of said first and second integral wing members which abut the outer panel being coated with a glue retarding coating to prevent bonding of said outer panel thereto, said inner panel further including first and second cut-outs, with a portion of the perimeter of each said cut-out being respectively defined by the bottom edge of said first and second wing members, said wing members being deformed inwardly to thereby form spaced side walls for the spout when said inner and outer tabs are pulled outwardly.

A blank for a carton having an integral pour spout, comprising:

generally rectangular front and back panels, each of said panels having generally rectangular panels hingedly connected to the upper and lower edges thereof;
a first generally rectangular side panel hingedly connected between adjacent side edges of said front and back panels, said first side wall panel having at least one generally rectangular panel hingedly connected to a free edge thereof;
a second generally rectangular side wall panel hingedly connected to a side edge of one of said front and back panels, said second side wall panel having generally rectangular panels hingedly connected to the upper and lower edges thereof;
a glue panel extending from the remaining side edge of one of said front and back panels, one of said panels including an opening therethrough and a tab member having a first end hingedly connected to said one panel, a second end defining a portion of the perimeter of said opening, and spaced side edges connecting said first and second ends,
another of said panels including a tab hingedly connected to the panel and wing members extending from opposite edges of said tab, said wing members being coated with a glue retarding coating to prevent bonding of said one panel thereto, said another panel further including first and second cut-outs with a portion of the perimeter of each said cut-out being respectively defined by the bottom edge of said wing members;
and
said one panel and said another panel being in registry with one another in the erected carton.
