- a front panel,
- a rear panel opposing said front panel,
- a first side panel joining said front panel to said rear panel, said first side panel comprising two portions joined by a first fin seal;
- a second side panel opposed to said first side panel and joining said front panel to said rear panel, said second side panel comprising two portions joined by a second fin seal; and
- a bottom panel joining said front panel, said rear panel, said first side panel, and said second side panel, said bottom panel comprising two portions joined by a third fin seal, said third fin seal overlapping said first fin seal and folded to form a first ear having a truncated tip with a first trihedral corner, said third fin seal overlapping said second fin seal and forming a second ear having a truncated tip with a second trihedral corner.
- 2. The package of claim 1 wherein at least one of said first ear and said second ear is provided with a tear line to permit a portion of said at least one of said first ear and said second ear to be relatively easily torn off to form an opening into the package.
- 3. A blank of flexible packaging sheet material for constructing a container comprising:
- a generally rectangular sheet of flexible packaging sheet material defining four corners;
- at least four spaced apart longitudinal fold lines scored into said sheet;
- at least four spaced apart transverse fold lines scored into said sheet; and
- four corner fold lines scored into said sheet, each corner fold line extending diagonally from an associated one of said corners of said sheet through the intersection of the transverse fold line most adjacent to the associated corner and the longitudinal fold line most adjacent to the associated corner to the intersection of the transverse fold line next most adjacent to the associated corner and the longitudinal fold line next most adjacent to the associated corner, wherein each of said corners of said sheet is trihedral.
- 4. The blank of claim 3 wherein said sheet includes a series of perforations forming a tear line defining a removable closure member.
- 5. The blank of claim 3 wherein one pair of longitudinally opposed ones of said corners are provided with mating tear lines.
- 6. The blank of claim 5 wherein said blank has a paper core, said paper core being perforated along said tear lines; said perforations being sealed on at least one side of said paper core so as to be leak-tight.
- 7. A blank of flexible packaging sheet material for constructing a container comprising:
- a generally rectangular sheet of flexible packaging sheet material;
- at least four spaced apart longitudinal fold lines scored into said sheet;
- at least four spaced apart transverse fold lines scored into said sheet; and
- an opening defined through said sheet, said opening having an outwardly bowed first edge, said opening having a second edge defined by a first inwardly extending tongue portion, said first tongue portion defining a first width, a third edge defined by a second inwardly extending tongue portion, and a fourth edge defined by a third tongue portion extending inwardly between said first and second tongue portions, said third tongue portion defining a length less than one third of said first width.
- 8. A blank of flexible packaging sheet material for constructing a container comprising:
- a sheet of flexible packaging sheet material having a generally rectangular first portion and a generally rectangular second portion spaced apart from said first portion;
- at least four spaced apart longitudinal fold lines scored into said sheet, each of said longitudinal fold lines extending across both said first portion and said second portion;
- a first pair of spaced apart transverse fold lines scored into said first portion of said sheet; and
- a second pair of spaced apart transverse fold lines scored into said second portion of said sheet,
- a trapezoidal portion of said sheet interposed between said first portion and said second portion, said trapezoidal portion being joined to said first portion along a first boundary, said trapezoidal portion being joined to said second portion along a second boundary, said trapezoidal portion cooperating with said first portion and said second portion to define a pair of peripheral edges of said sheet which are each inwardly tapered along said trapezoidal portion from said second portion toward said first portion such that each of said second pair of transverse fold lines is longer than either of said first pair of transverse fold lines.
- 9. A package having a first fin seal, a second fin seal spaced apart from said first fin seal, and a third fin seal overlapping said first and second fin seals, said package further having a front panel, a second panel extending at an angle to said front panel and cooperating with said front panel to define an opening therethrough, and a tab having a first portion removably fixed to said front panel, a second portion hingedly connected to said first portion and removably fixed to said second panel, and a grip portion hingedly connected to said first portion, said first portion and said second portion forming a leak tight seal over said opening.
- 10. A package comprising:
- a front panel;
- a rear panel opposing said front panel;
- a first side panel joining said front panel to said rear panel, said first side panel comprising two portions joined by a first fin seal;
- a second side panel opposed to said first side panel and joining said front panel to said rear panel, said second side panel comprising two portions joined by a second fin seal;
- a bottom panel joining said front panel, said rear panel, said first side panel, and said second side panels, said bottom panel comprising two portions joined by a third fin seal, said third fin seal overlapping said first and second fin seals;
- a top panel opposed to said bottom panel and joining said front panel, said rear panel, said first side panel, said second side panel, said top panel cooperating with said front panel, said rear panel, said first side panel, said second side panel and said bottom panel to define an interior surface of said package which encloses an internal volume of said package; and
- a plastic insert having an external portion disposed outside of said internal volume defined by said interior surface, said external portion defining a first maximum diameter, said insert further having a neck portion defining a second maximum diameter and extending through an opening defined in a selected one of said front panel, said rear panel, said first side panel, said second side panel, said bottom panel, and said top panel, said opening having a diameter greater than said first and second maximum diameters, said insert further having a flange portion sealed to said interior surface of said package about said opening.
- 11. The package of claim 10 wherein said plastic insert defines an opening therethrough, said neck portion defining an outer surfaces, a portion of said outer surface of said neck portion being threaded, said external portion of said insert including a cap removably threaded on to said neck portion to selectively seal said opening through said plastic insert.
- 12. The package of claim 10 wherein said flange portion of said plastic insert is heat bonded to a portion of said interior surface of said package.
