An easy-open encasement formed of a soft encasement member in the form of a film. An opening or an openable portion is formed in the soft encasement member, which allows a user to extract contents from the encasement. Furthermore, a lid member, which can be peelably adhered to the soft encasement member, is adhered to the surface of the soft encasement member such that it covers the opening or openable portion. With such a structure, a tab is provided at a part of the perimeter of the lid member, which serves as a starting point that allows the user to peel off the lid member. Furthermore, the tab includes a hinge portion, which allows the user to raise the tab, or a flap elevated from the surface of the encasement.

What is claimed is: 1. An encasement comprising: an encasement member; an opening or an openable portion formed in said encasement member; a lid member peelably adhered to an upper surface of said encasement member and covering said opening or said openable portion; wherein the lid member includes a tab adapted to be raised by a user to peel off said lid member; and a hinge portion located between the tab and a remainder of the lid member for the user to raise said tab, wherein said hinge portion is formed of a weak line on said lid member in a continuous or discontinuous manner, wherein the lid member includes a first sheet defining an inner surface of the lid member facing the upper surface of the encasement member, and a second sheet defining an outer surface of the lid member, wherein the first sheet on said hinge portion includes a structure having a thickness difference from that of a remainder of the first sheet. 2. The encasement according to claim 1, wherein said weak line comprises at least one of a slit tear line, a half-cut line, or an embossed line. 3. The encasement according to claim 1, wherein said hinge portion is provided around a base of said tab such that it extends along a direction approximately orthogonal to the direction along which said tab is to be raised, and wherein said hinge portion includes an approximately U-shaped slit tear line extending opposite to the direction along which said tab is to be raised, and said weak lines which extend from both ends of said approximately U-shaped slit tear line to the respective side edges of said tab. 4. The encasement according to claim 1, wherein said structure of the first sheet is a looped portion that is free of directly attachment to the second sheet of the hinge portion, so that the tab is adapted to be elevated by folding the tab along the looped portion. 5. The encasement according to claim 1, wherein said structure of the first sheet is a cut dividing the first sheet into two portions corresponding to the tab and the remainder of the lid member, respectively. 6. The encasement according to claim 5, wherein said two portions of the first sheet corresponding to the tab and the remainder of the lid member have different thicknesses. 7. The encasement according to claim 1, wherein said lid member further comprises a third sheet directly adhered to the first sheet at a portion corresponding to the tab or a portion corresponding to the remainder of the lid member and the third sheet has en edge defining the weak line. 8. The encasement according to claim 1, wherein the tab of the lid member has an end portion folded back and directly bonded to the first sheet. 9. The encasement according to claim 1, wherein the tab of the lid member protrudes, while remaining parallel to the upper surface of the encasement member, from the upper surface of the encasement member and said tab is free of direct contact to the encasement member. 10. The encasement according to claim 1, wherein the hinge portion includes a first weak line having a first end; a second weak line having a second end opposite to the first end, wherein the first weak line extends from the first end away from the second weak line to a first side edge of the tab, the second weak line extends from the second end away from the first weak line to a second side edge of the tab, which the second side edge is opposite to the first side edge of the tab, and a slit tear line extending through an entire thickness of the lid member, said slit tear line projecting away from the tab and connecting the first and second ends of the first and second weak lines, respectively. 11. The encasement according to claim 10, wherein a tongue portion is defined by the slit tear line, and adapted to be folded downward toward the upper surface of the inner encasement when the tab is raised upward by the user. 12. A double-encasement comprising: an inner encasement; and an outer container containing therein the inner encasement, wherein said inner encasement comprises: an opening or an openable portion formed in said inner encasement; a lid member peelably adhered to an upper surface of said inner encasement and covering said opening or said openable portion; wherein the lid member includes a tab adapted to be raised by a user to peel off said lid member; and a hinge portion located between the tab and a remainder of the lid member for the user to raise said tab, said outer container comprises: an exposed opening through which said lid member of said inner encasement is exposed and a cap portion for covering said exposed opening and adapted to be opened or closed by the user, and said tab of said lid member extends from within said outer container outwardly through the exposed opening, wherein said tab of said lid member rests on and directly contacts an edge of said exposed opening. 13. The double-encasement according to claim 12, wherein said hinge portion is formed of a weak line on said lid member in a continuous or discontinuous manner. 14. The double-encasement according to claim 12, wherein said weak line comprises at least one of a slit tear line, a half-cut line, or an embossed line. 15. A double-encasement comprising: an inner encasement; and an outer container containing therein the inner encasement, wherein said inner encasement comprises: an opening or an openable portion formed in said inner encasement; a lid member peelably adhered to an upper surface of said inner encasement and covering said opening or said openable portion; wherein the lid member includes a tab adapted to be raised by a user to peel off said lid member; and a hinge portion located between the tab and a remainder of the lid member for the user to raise said tab, said outer container comprises: an exposed opening through which said lid member of said inner encasement is exposed; and a cap portion for covering said exposed opening and adapted to be opened or closed by the user, and said tab of said lid member extends from within said outer container outwardly through the exposed opening, wherein the hinge portion includes a first weak line having a first end; a second weak line having a second end opposite to the first end, wherein the first weak line extends from the first end away from the second weak line to a first side edge of the tab, the second weak line extends from the second end away from the first weak line to a second side edge of the tab, which second side edge is opposite to the first side edge of the tab, and a slit tear line extending through an entire thickness of the lid member, said slit tear line projecting away from the tab and connecting the two opposite ends of the weak lines, wherein a tongue portion is defined by the slit tear line, and adapted to be folded downward toward the upper surface of the inner encasement when the tab is raised upward by the user. 16. The double-encasement according to claim 12, wherein the lid member includes a first sheet defining an inner surface of the lid member facing the upper surface of the inner encasement, and a second sheet defining an outer surface of the lid member, wherein the first sheet on said hinge portion includes a structure having a thickness different from that of a remainder of the first sheet.
