A rigid holding container has a flexible cover sheet extending over the holding area for sealing the contents. The container has a wide, flat perimeter lip which provides a firm base for the seal between the cover sheet and the container. A breaching bubble is formed in the seal, under the cover and over the perimeter lip. The consumer breaches the bubble by pressing the bubble against the lip between the thumb and forefinger. The pressure compresses the air in the bubble causing the bubble to expand laterally. The expanding bubble breaches along the perimeter of the lip, producing a peel flap of flexible cover material. The consumer pulls the peel flap while holding the rigid container down, to remove the cover sheet.

1. A process for producing a package comprising: thermo-forming a material into a support, the support comprising an item compartment surrounded by a compartment perimeter and an overhang extending beyond the item compartment, the overhang comprising a bubble compartment surrounded by a bubble perimeter with a concave aspect located within a corner of the overhang and outside of the compartment perimeter;loading an item into the item compartment;attaching to the compartment perimeter and to the bubble perimeter a flexible closure, the flexible closure forming a peripheral seal around the compartment perimeter and forming a bubble seal around the bubble perimeter, a breachable bubble being formed between a thermoformed lip of the bubble perimeter and the flexible closure; andforming a breachable portion along the bubble seal at the concave aspect of the bubble perimeter, wherein the breachable portion of the bubble seal comprises a peel seal, the peel seal comprising: (a) a first portion adhesively secured to a second portion along the seal, the first portion comprising an adhesive layer, the second portion comprising a release layer; or(b) a first portion secured to a second portion along the seal, the first portion and the second portion both comprising a film, the first portion comprising an adhesive component and a contact layer, the second portion also comprising a contact layer, wherein the contact layer of the first portion is bonded to the contact layer of the second portion and wherein, when the bubble is breached, the contact layer of the first portion separates from the adhesive component; andwherein the breachable bubble is configured for thumb-and-finger pinching, and wherein when pressure is applied to the breachable bubble from said pinching, an atmosphere within the breachable bubble applies pressure to the bubble seal which causes an edge breach at the breachable portion of the bubble seal, the edge breach providing a peelable edge at the concave aspect for facilitating opening of the item compartment. 2. A process as defined in claim 1, further comprising: a flexible peel tab formed by the flexible closure along the bubble perimeter. 3. A process as defined in claim 2, wherein the flexible peel tab is proximate a fringe of the flexible closure. 4. A process as defined in claim 1, wherein: the bubble compartment defines a volume, and the volume within the bubble compartment displaces the flexible closure away from the overhang, and an edge breach is created by pressing the flexible closure against the overhang creating pressure in the bubble compartment. 5. A process as defined in claim 4, further comprising a void adjacent to the overhang on the support. 6. A process as defined in claim 1, wherein the flexible closure is transparent or translucent. 7. A process as defined in claim 1, wherein the peripheral seal is frangible for permitting disengagement of the flexible closure from the support along the peripheral seal. 8. A process as defined in claim 1, wherein the item in the tray is vacuum packed. 9. A process as defined in claim 1, wherein the item in the tray is in a controlled atmosphere. 10. A process as defined in claim 1, wherein the breachable bubble contains a gas, the gas comprising an antimicrobial agent. 11. A process as defined in claim 1, wherein the item compartment contains a first gas and the breachable bubble contains a second gas and wherein the first gas within the item compartment is different than the second gas contained within the breachable bubble. 12. A process as defined in claim 1, wherein the breachable bubble is placed on the underside of the overhang and the flexible closure wraps around the perimeter of the support. 13. A process for producing a package comprising: thermo-forming a material into a support, the support comprising an item compartment surrounded by a compartment perimeter and an overhang extending beyond the item compartment, the overhang comprising a bubble compartment surrounded by a bubble perimeter located within a corner of the overhang and outside of the compartment perimeter;loading an item into the item compartment;attaching to the compartment perimeter and to the bubble perimeter a flexible closure, the flexible closure forming a peripheral seal around the compartment perimeter and forming a bubble seal around the bubble perimeter, a breachable bubble being formed between a thermoformed lip of the bubble perimeter and the flexible closure;forming a gas-tight seal between the flexible closure and the support;creating a sterile environment within the item compartment, the sterile environment comprising: (a) a vacuum;(b) a gaseous environment containing an inert gas; or(c) a gaseous environment containing an antimicrobial agent comprising a gaseous chemosterilizer; andforming a breachable portion of the bubble seal, the breachable portion located along a portion of the bubble seal at a concave or convex aspect of the bubble seal at a corner of the bubble perimeter, the corner of the bubble perimeter facing an outermost edge of the package wherein when pressure is applied to the breachable bubble, an atmosphere within the breachable bubble applies pressure to the bubble seal which causes an edge breach at the breachable portion of the bubble seal, the edge breach providing a peelable edge at the breachable portion for facilitating opening of the item compartment. 14. A process as defined in claim 13, wherein the sterile environment comprises the gaseous environment containing the gaseous chemosterilizer, the gaseous chemosterilizer comprising ethylene oxide, propylene oxide, beta-propiolactone, ozone, carbon dioxide, a halogen gas, or mixtures thereof. 15. A process as defined in claim 13, wherein: the bubble compartment defines a volume, and the volume within the bubble compartment displaces the flexible closure away from the support, and an edge breach is created by pressing the flexible closure against the support creating pressure in the bubble compartment. 16. A process as defined in claim 13, wherein the peripheral seal is frangible for permitting disengagement of the flexible closure from the support along the peripheral seal. 17. A process as defined in claim 13, wherein the breathable bubble is positioned at one side of the package, the side of the package having a length, the length of the breachable bubble being greater than half the length of the side of the package. 18. A process as defined in claim 13, further comprising the step of creating a sterile environment within the bubble compartment. 19. A process as defined in claim 1, wherein after the breachable bubble is breached, the bubble seal is resealable. 20. A process for producing a package comprising: thermo-forming a material into a support, the support comprising an item compartment surrounded by a compartment perimeter and an overhang extending beyond the item compartment, the overhang comprising a bubble compartment surrounded by a bubble perimeter located within a corner of the overhang and outside of the compartment perimeter;loading an item into the item compartment;attaching to the compartment perimeter and to the bubble perimeter a flexible closure, the flexible closure forming a peripheral seal around the compartment perimeter and forming a bubble seal around the bubble perimeter, a breachable bubble being formed between a thermoformed lip of the bubble perimeter and the flexible closure;forming a breachable portion of the bubble seal, the breachable portion located along a portion of the bubble seal at to a concave or convex aspect of the bubble seal at a corner of the bubble perimeter, the corner of the bubble perimeter facing an outermost edge of the package, wherein when pressure is applied to the breachable bubble, an atmosphere within the breachable bubble applies pressure to the bubble seal which causes an edge breach at the breachable portion of the bubble seal, the edge breach providing a peelable edge at the breathable portion for facilitating opening of the item compartment.
