1. A can having an easy opening panel, comprising: a tab connected via a rivet structure to the panel, wherein the tab comprises a tab rear part for gripping and actuation, and a tab front part for opening the can upon tab actuation such that tilting of the tab results in opening of the can along a
1. A can having an easy opening panel, comprising: a tab connected via a rivet structure to the panel, wherein the tab comprises a tab rear part for gripping and actuation, and a tab front part for opening the can upon tab actuation such that tilting of the tab results in opening of the can along a score line formed in the panel, wherein the panel comprises, at least beneath the tab front part, a deformable, compressed panel structure deformable upon an increase in can internal pressure, wherein the deformable, compressed panel structure is located beneath the tab front part, wherein the deformable, compressed panel structure includes a compressed structure that compensates for stress elongation upon increased can internal pressure, wherein the deformation of the deformable, compressed panel structure by stress elongation of the deformable, compressed panel structure beneath the tab front part forms or increases a finger access gap between the tab rear part and the panel, and does not result in an interference of an opening of the can by a consumer actuating the tab, wherein the deformable, compressed panel structure has the form of a bead partly circumventing or encircling the rivet structure, and wherein the stress elongation of the deformable, compressed panel is caused by increased can internal pressure. 2. The can according to claim 1, wherein the deformable, compressed panel structure bead extends inwardly or outwardly. 3. The can according to claim 1, wherein the deformable, compressed panel structure bead circumferentially extends over one of 270°, 180°, and 120°. 4. The can according to claim 1, wherein the deformable, compressed panel structure limits upon can internal pressure the tab lift of the tab rear part to less than 4 mm above a can rim. 5. The can according to claim 4, wherein limitation of the tab lift occurs at a can internal pressure of 0.6-3.0 bar. 6. The can according to claim 4, wherein limitation of the tab lift occurs at a can internal pressure of 1.0-2.8 bar. 7. The can according to claim 4, wherein limitation of the tab lift occurs at a can internal pressure of 1.5-2.5 bar. 8. The can according to claim 1, wherein the can has a can diameter of 32-120 mm. 9. The can according to claim 1, wherein upon partial relief of the can internal pressure the deformable, compressed panel structure reforms such that the tab rear part resides beneath a can rim. 10. The can according to claim 1, wherein the formation or increase of the finger access gap results from a negative pressure difference between the outside and content of the can. 11. The can according to claim 1, wherein the formation or increase of the finger access gap results from a mechanical impact on the deformable, compressed panel structure. 12. The can according to claim 1, wherein the deformable, compressed panel structure limits upon can internal pressure the tab lift of the tab rear part to less than 3.5 mm above a can rim. 13. The can according to claim 1, wherein the deformable panel structure limits upon can internal pressure the tab lift of the tab rear part to less than 3.0 mm above a can rim. 14. The can according to claim 1, wherein the can has a can diameter of 45-102 mm. 15. The can according to claim 1, wherein the can has a can diameter of 45-96 mm. 16. An easy opening panel comprising a tab connected via a rivet structure to the panel, wherein the tab comprises a tab rear part for gripping and actuation, and a tab front part for opening the can upon tab actuation such that tilting of the tab results in opening of the can along a score line formed in the panel, wherein the panel comprises, at least beneath the tab front part, a deformable, compressed panel structure deformable upon an increase in can internal pressure, wherein the deformable, compressed panel structure is located beneath the tab front part, wherein the deformable, compressed panel structure includes a compressed structure that compensates for stress elongation upon increased can internal pressure, wherein the deformation of the deformable, compressed panel structure by stress elongation of the deformable, compressed panel structure beneath the tab front part forms or increases a finger access gap between the tab rear part and the panel, and does not result in an interference of an opening of the can by a consumer actuating the tab, wherein the deformable, compressed panel structure has the form of a bead partly circumventing or encircling the rivet structure, and wherein the stress elongation of the deformable, compressed panel is caused by increased can internal pressure. 17. A panel for a can, the panel comprising a tab connected via a rivet structure to the panel and a deformable, compressed panel structure deformable upon can internal pressure, wherein the tab comprises a tab rear part for gripping and actuation, and a tab front part for opening the can upon tab actuation such that tilting of the tab results in opening of the can along a score line formed in the panel, wherein the panel comprises, at least beneath the tab front part, the deformable, compressed panel structure, wherein the deformable, compressed panel structure is located beneath the tab front part, wherein the deformable, compressed panel structure includes a compressed structure that compensates for stress elongation upon increased can internal pressure, wherein the deformation of the deformable, compressed panel structure by stress elongation of the deformable, compressed panel structure beneath the tab front part forms or increases a finger access gap between the tab rear part and the panel, and does not result in an interference of an opening of the can by a consumer actuating the tab, wherein the deformable, compressed panel structure has the form of a bead partly circumventing or encircling the rivet structure, wherein the stress elongation of the deformable, compressed panel is caused by increased can internal pressure, and wherein upon partial relief of the can internal pressure the deformable, compressed panel structure reforms such that the tab rear part resides beneath a can rim.
