Microwave heating construct with elevatable bottom

A microwave heating construct, comprising:

• a top panel and a bottom panel in an opposed relationship with one another, the top panel and the bottom panel each comprising microwave energy interactive material operative for heating in response to microwave energy;
• and
• a plurality of side panels extending upwardly from peripheral edges of the bottom panel,
• wherein
• the bottom panel includes a movable portion defined at least partially by
• a breachable line of disruption extending across the bottom panel between each pair of adjacent peripheral edges of the bottom panel, and
• a fold line extending between each adjacent pair of breachable lines of disruption,
• wherein breaching each breachable line of disruption is for allowing the movable portion of the bottom panel to move towards the top panel to bring a food item positioned on the movable portion of the bottom panel into closer proximity with the microwave energy interactive material of the top panel, and
• the side panels each include a hingeable portion foldably joined to the movable portion of the bottom panel, wherein the hingeable portion of each side panel is for being moved with the movable portion of the bottom panel.

A microwave heating construct, comprising:

• a top panel and a bottom panel opposite one another, wherein the top panel and the bottom panel each include microwave energy interactive material operative for converting microwave energy into thermal energy, wherein the bottom panel includes a movable portion defined at least partially by
• a plurality of lines of disruption extending across the bottom panel between pairs of adjacent peripheral edges of the bottom panel, and
• a plurality of fold lines extending between adjacent pairs of the plurality of lines of disruption,
• wherein the movable portion of the bottom panel is for being moved towards the top panel, so that
• a food item seated on the movable portion of the bottom panel is brought closer to the microwave energy interactive material of the top panel, and
• a void is defined beneath the movable portion of the bottom panel;
• and
• a plurality of side panels joined to the bottom panel, wherein the side panels each include a hingeable portion joined to the movable portion of the bottom panel along a respective one of the peripheral edges of the bottom panel, wherein the hingeable portion of each side panel is for being moved with the movable portion of the bottom panel.

A microwave heating construct, comprising:

• a top panel and a bottom panel opposite one another, wherein at least one of the top panel and the bottom panel includes microwave energy interactive material operative for generating heat when sufficiently exposed to microwave energy, wherein the bottom panel includes a movable portion defined at least partially by
• a plurality of lines of disruption extending across the bottom panel between pairs of adjacent peripheral edges of the bottom panel, and
• a plurality of fold lines extending between adjacent pairs of the plurality of lines of disruption,
• wherein the movable portion of the bottom panel is for being moved towards the top panel, so that
• a void is defined beneath the movable portion of the bottom panel, and
• venting gaps are defined adjacent to the lines of disruption extending across the bottom panel;
• and
• a plurality of side panels extending upwardly from the bottom panel, wherein the side panels each include a hingeable portion foldably joined to the movable portion of the bottom panel, wherein the hingeable portion of each side panel is for being moved with the movable portion of the bottom panel.
