The present invention relates to an air-tight closure for enhancing accessibility to contents of a container when the container is opened and for preventing exposure of the container contents to ambient air when the container is closed. The invention further relates to re-closable containers including the same. The closure comprises at least two elongated male units disposed a gap apart on the outer surface of one wall of the container and at least two corresponding elongated female units disposed a gap apart on the outer surface of an opposite wall of the container opposite the male units, forming at least two male-female pairs. The closure may further include a tongue for facilitating opening the container.

What is claimed is: 1. In combination a container and a closure for enhancing accessibility to contents of the container when the container is opened and for minimizing exposure of the container contents to ambient air when the container is closed, the container is having two opposite walls connected to each other and a mouth for providing an access to the container contents, each of said two opposite walls is having an inner surface and an outer surface, the closure comprising: two separate elongated male units, each having a longitudinal axis, the two male units being disposed a gap apart completely separated from each other by said gap on the outer surface of one of said two opposite walls adjacent to the mouth, such that the longitudinal axes of said two male members coincide with each other; two separate corresponding elongated female units, each having a longitudinal axis, the two female units being disposed a gap apart completely separated from each other by said gap on the outer surface of the second wall opposite the two male units such that the longitudinal axes of said two female members coincide with each other, wherein the male and female units are configured to snap fit into each other so as to form two separate male-female pairs; and at least one pulling tongue member connected to at least one of the male units or to at least one of the female units for facilitating opening the closure. 2. The container of claim 1 wherein the container is a flexible package fabricated from a single layer or a multiple layer sheet material. 3. The container of claim 1 wherein the container is a non-gusseted package and wherein said two walls are directly connected to each other. 4. The container of claim 1 wherein the container is a gusseted package having two side walls interposed between said two opposite walls. 5. The container of claim 1 wherein the mouth is initially sealed. 6. The container of claim 1 wherein the closure is fabricated from rigid or semi-rigid material. 7. The container of claim 1 wherein the closure is made of plastic material. 8. The container of claim 1 wherein the closure is made of metal or metal alloy. 9. The container of claim 1 wherein each male unit comprises two flat elongated wings and an elongated projection interposed there between and wherein each female unit comprises two flat elongated wings and an elongated recess portion interposed there between, said elongated projection and said elongated recess portion are having complementary profiles for allowing snap fitting said projection into said recess portion. 10. The container of claim 1 wherein the male unit and the female unit of each of said two male-female pairs when manufactured are connected to each other by two elongated strips interposed there between, the two elongated strips are connected to each other and to the male and female units by thin breakable connections for allowing securing the closure to the mouth of the container strips by folding the closure around the connection between said two elongated strips such that one elongated strip connected to the male unit of said male-female pair is disposed on one wall of the container and the second elongated strip connected to the female unit of said male-female pair is disposed on the second wall of the container. 11. The container of claim 1 wherein the closure is disposed diagonally on said two opposite walls. 12. The container of claim 1 wherein the mouth is sealed by a sealing strip comprising a first portion and a second portion separated by a sealing wherein at least one of the two male-female pairs is disposed below the first portion leaving an unsealed strip between said at least one male-female pair and said first portion and wherein at least another one of the two male-female pairs is disposed at least partly on the second portion. 13. The container of claim 1 wherein the at least one pulling tongue member comprises a first tongue connected to at least one of the two male units and a second tongue connected to at least one of the two female units. 14. The container of claim 1 wherein said at least one tongue member is connected to both male units or to both female units. 15. The container of claim 14 wherein the tongue member includes a cut to match the gap between the two male or the two female units. 16. The container of claim 1 wherein the tongue member is made of a flexible material. 17. The container of claim 1 wherein the tongue member is made of the same material as the closure. 18. A re-closable container comprising: two opposite walls connected to each other, each having an inner surface and an outer surface; a mouth for providing an access to the container contents; and a closure, the closure comprises two or three elongated male units, each having a longitudinal axis, the two or three male units being disposed a gap apart completely separated from each other on the outer surface of one of said two opposite walls adjacent to the mouth, such that the longitudinal axes of said two or three male units coincide with each other; two or three elongated corresponding female units, each having a longitudinal axis, the two or three female units being disposed a gap apart completely separated from each other on the outer surface of the second wall opposite the male units, the longitudinal axes of said female units coincide with each other; the male and female units are configured to snap fit into each other; and at least one tongue member connected to at least one of the elongated male units or to at least one of the elongated female units for facilitating opening the closure. 19. The container of claim 18 wherein the container is a flexible package fabricated from a single layer or a multiple layer sheet material. 20. The container of claim 18 wherein the two opposite walls are directly connected to each other. 21. The container of claim 18 further comprising two side walls interposed between said two opposite walls. 22. The container of claim 18 wherein the mouth is initially sealed. 23. The container of claim 18 wherein the closure is disposed diagonally on said two opposite walls. 24. The container of claim 18 provided with a first tongue member connected to at least one of the male units and a second tongue member connected to at least one of the female units. 25. The container of claim 18 wherein said at least one tongue member is connected to two of the at least two or three male units or to two of the at least two or three female units. 26. The container of claim 18 wherein the tongue member includes a cut to match the gap between the male or female units. 27. The container of claim 18 wherein the tongue member is made of flexible material. 28. The container of claim 18 wherein the tongue member is an integral part of the closure. 29. The container of claim 18 wherein the tongue member is configured as a pull-ring. 30. A re-closable container comprising: two opposite walls connected to each other, each having an inner surface and an outer surface; a mouth for providing an access to the container contents; and a closure, the closure comprises two or three elongated male units, each having a longitudinal axis, disposed a gap apart on the outer surface of one of said two opposite walls adjacent to the mouth, such that the longitudinal axes of said male members coincide with each other; two or three elongated corresponding female units, each having a longitudinal axis, disposed a gap apart on the outer surface of the second wall opposite the male members, the longitudinal axes of said female members coincide with each other; the male and female units are configured to snap fit into each other; and at least one tongue member connected to two adjacent male units or to two adjacent female units wherein said tongue member includes a cut to match the gap between the two adjacent male or female units.
