An opening device for a flexible package having an opening portion defined by two side walls and a width, the opening device intended to be disposed in the opening portion of the package adjacent to an opening, formed upon initial opening of the package, for opening and closing thereof. The opening device comprises a thin-walled first body with a contact surface and a first application surface opposite thereto for allowing application of the first body in the opening portion to a first of the two side walls. The first body is maneuverable, by folding about a first folding axis, between a basic position and a sealing position. In the sealing position, the contact surface has sub portions directly facing each other. A locking member is designed for releasable locking of the body in the sealing position.

1. An opening device for a flexible package, having an opening portion which is defined by two side walls and a width, which opening device is intended to be disposed in the opening portion of the package adjacent to an opening, formed upon initial opening of the package, for opening and closing thereof, which opening device comprises:a thin-walled first body with a contact surface and a first application surface opposite thereto for allowing application of the first body in the opening portion to a first of the two side walls, anda locking member,which first body is maneuverable, by folding about a first folding axis, between a basic position and a sealing position, in which sealing position the contact surface has sub portions directly facing each other,wherein the sub portions adjoin each other along a boundary portion which is designed to extend along substantially the full width of the opening portion, andwherein the locking member is designed for releasable locking of the body in the sealing position, andwherein the locking member is disposed in at least one of the sub portions of the contact surface and is designed to act between the sub portions in order to achieve the releasable locking. 2. The opening device according to claim 1, in which a first hinge joint, having an extent which coincides with the first folding axis, is configured in the boundary portion of the first body. 3. The opening device according to claim 2, in which the first hinge joint has a v-shaped or w-shaped cross section. 4. The opening device according to claim 1, in which the locking member forms a spacer element which mutually separates the sub portions of the contact surface in the sealing position of the first body. 5. The opening device according to claim 1, wherein the first body is maneuverable between the basic position and an opening position by folding about a second folding axis extended transversely to the first folding axis. 6. The opening device according to claim 5, in which a second hinge joint having an extent which coincides with the second folding axis is configured in the first body. 7. The opening device according to claim 5, in which the first application surface has, in the opening position of the first body, two sub portions angled relative to each other. 8. The opening device according to claim 5, further comprising a second body extended along a longitudinal axis and having a second application surface for allowing application of the second body in the opening portion to a second of the two side walls, wherein the second body is maneuverable between an unfolded position and a folded position by folding about a third folding axis, the second body being intended for maneuvering into the folded position in connection with maneuvering of the first body into its opening position. 9. The opening device according to claim 8, in which the first body has a first width and the second body has a second width, wherein the second width is less than half the first width. 10. The opening device according to claim 8, in which the first body has a first length and the second body has a second length, wherein the second length is equal to or less than the first length. 11. The opening device according to claim 8, in which a third hinge joint, having an extent which coincides with the third folding axis, is configured in the second body. 12. The opening device according to claim 1, in which the locking member is designed for point locking. 13. The opening device according to claim 1, in which the locking member is designed for linear locking. 14. The opening device according to claim 1, in which the locking member is designed for mechanical locking. 15. The opening device according to claim 1, in which the locking member is designed for mechanical locking by snap action. 16. The opening device according to claim 1, in which the locking member is designed for locking with the aid of an adhesive. 17. The opening device according to claim 1, wherein the opening device is made of a plastics material having a thickness within the range of 0.1-1mm. 18. The opening device according to claim 1, wherein the application surface is provided with an adhesive layer comprising a hot melt adhesive. 19. The opening device according to claim 18, wherein the adhesive layer covers the application surface. 20. The opening device according to claim 18, wherein the adhesive layer has an undulated surface. 21. A flexible package having an opening portion defined by two side walls, comprising: an opening device which is disposed in the opening portion adjacent to an opening, formed upon initial opening of the package, for opening and closing thereof, the opening device comprising:a thin-walled first body with a contact surface,a first application surface opposite thereto by which the first body is fastened to an external surface of a first of the side walls of the package, anda locking member,which first body is maneuverable, by folding about a first folding axis, between a basic position and a sealing position, in which sealing position the contact surface has sub portions directly facing each other, andwhich locking member is disposed in at least one of the sub portions of the contact surface and is designed to act between the sub portions in order to achieve releasable locking of the body in the sealing position,wherein the first folding axis of the first body is oriented parallel with the opening, andwherein the package is maneuverable into a resealed state in which an end section of the opening portion comprising the opening is folded about the first folding axis by maneuvering of the first body into the sealing position. 22. The flexible package according to claim 21, in which the first body of the opening device is maneuverable, by folding about a second folding axis extended transversely to the first folding axis, between the basic position and an opening position, wherein the package is maneuverable into an opened-up state in which the side walls in the opening portion are separated by maneuvering of the first body into the opening position. 23. The flexible package according to claim 22, in which the opening device further comprises a second body extended along a longitudinal axis and having a second application surface by which the second body is fastened to an external surface of a second of the two side walls, which second body is maneuverable, by folding about a third folding axis, between an unfolded position and a folded position,wherein the package is maneuverable into the opened-up state by maneuvering of the second body into the folded position in connection with maneuvering of the first body into the opening position. 24. The flexible package according to claim 23, in which the first body and the second body are disposed in the opening portion on the first side wall and second side wall respectively of the package such that the second body is situated within a region defined by the contour of one of the sub portions of the first body. 25. The flexible package according to claim 23, wherein the second folding axis of the first body is displaced in parallel with respect to the third folding axis of the second body.
