Abstract

A microwave popcorn package is provided. The preferred package includes a flexible bag construction reinforced with a sidewall construction. The package is such that the flexible bag construction and the sidewall construction are selectively expandable between a collapsed configuration and an expanded configuration. After the package is opened, the sidewall construction provides for a rigid sidewall to provide a stand up bowl for access to the popped popcorn.

Claims (16)

1. A microwave package comprising:

a sidewall construction defining an interior, the sidewall construction including a first side panel having a base end portion and a second side panel having a base end portion, the base end portions of the first side panel and the second side panel forming an opening at a base of the microwave popcorn package, the sidewall construction being selectively expandable between a collapsed configuration and an expanded configuration, wherein the sidewall construction is a vertically rigid material; and

a flexible bag construction having a base enclosing the opening formed by the base end portions of the first side panel and second side panel, a portion of the flexible bag construction being secured to the interior of the sidewall construction, the flexible bag construction being selectively expandable between the collapsed configuration and the expanded configuration, wherein the flexible bag construction and the sidewall construction form a container having vertically rigid sidewalls in the expanded configuration.

2. A microwave package as claimed in claim 1 , wherein the base is a bottom gusset.

3. A microwave package as claimed in claim 2 , wherein the bottom gusset is directed inwardly between a first side and a second side of the flexible bag construction in the collapsed configuration.

4. A microwave package as claimed in claim 1 , wherein the sidewall construction defines a ring configuration.

5. A microwave package as claimed in claim 1 , wherein the sidewall construction includes a plurality of creases for adaptation from the collapsed configuration to the expanded configuration.

6. A microwave package as claimed in claim 1 , wherein the flexible bag construction includes an outward projecting-portion that projects outwardly from the sidewall construction and is adapted to be removed from a remainder of the flexible bag construction.

7. A microwave package as claimed in claim 6 , wherein the outward projecting-portion projects outwardly from the sidewall construction in the collapsed configuration.

8. A microwave package as claimed in claim 6 , wherein a tear strip that is selectively removable is disposed around the portion of the flexible bag construction that extends outwardly from the sidewall construction.

9. A microwave package as claimed in claim 1 , further comprising a microwave interactive construction positioned in thermoconductive relation to the sidewall construction.

10. A microwave package as claimed in claim 9 , wherein the flexible bag construction includes an outer ply and an inner ply with the microwave interactive construction positioned between the outer and inner plies.

11. A microwave popcorn package comprising:

a sidewall construction having a first side panel having a base end portion and a second side panel having a base end portion,. the sidewall construction defining an interior between the first and second side panels, the base end portions of the first side panel and the second side panel forming an opening at a base of the microwave popcorn package, the sidewall construction being selectively expandable between a collapsed configuration and an expanded configuration, wherein the sidewall construction is a vertically rigid material that forms vertically rigid sidewalls in the expanded configuration;

a flexible bag construction having a first side, a portion of which is secured to the first side panel of the sidewall construction, a second side, a portion of which is secured to the second side panel of the sidewall construction, and a base extending between the first and second sides of the flexible bag construction, the flexible bag construction being selectively expandable between the collapsed configuration and the expanded configuration, wherein the first side, the second side, and the base of the flexible bag construction define an interior, the base of the flexible bag construction is configured within the opening formed by the base end portions of the first side panel and second side panel; and

a popcorn charge disposed in the interior of the flexible bag construction.
