A hinged guarantee closure is produced by being injection moulded in the closed state, i.e., with a guarantee seal. The closure is injection moulded with an associated ring member for connection to the container on which the closure is to be used. The ring member is separated from the rest of the closure by an axial gap which is spanned by a hinge portion and a guarantee connection. The closure comprises a cap with an integral closing member for cooperation with an opening in the container.

The invention claimed is: 1. A method for providing a hinged guarantee closure for a container, said closure comprising a non-threaded cap having an integral closing member for closing cooperation with an opening in said container, and a ring member for connection to said container, the ring member
The invention claimed is: 1. A method for providing a hinged guarantee closure for a container, said closure comprising a non-threaded cap having an integral closing member for closing cooperation with an opening in said container, and a ring member for connection to said container, the ring member encircles the container at a position such that the ring member is prevented from moving axially relative to the container, the method comprising injection moulding the guarantee closure in a closed state, with a guarantee seal, the closure being injection moulded, by using a mould having a collapsible core, in such a form that the moulded closure comprises said cap and said ring member, connected by a hinge element and at least one guarantee connection, axially spaced from each other, whereby said guarantee connection is formed generally flush with exterior surfaces of the cap and ring members; the hinge element is located at a periphery of the cap. 2. The method of claim 1, wherein the ring member is injection moulded with a coupling part that cooperates with a coupling part on the container. 3. The method of claim 2, wherein the ring member is injection moulded having an internal circumferential snap edge. 4. The method of claim 1, wherein the guarantee connection is made so that it is clear whether the guarantee connection has been broken or not. 5. A method for providing a hinged guarantee closure on a container opening, said closure comprising a non-threaded cap having an integral closing member for closing cooperation with the container opening and a ring member for connection to the container, the ring member encircles the container at a position such that the ring member is prevented from moving axially relative to the container, the method comprising injection moulding the closure in a closed state, with a guarantee seal, the closure being injection moulded, by using a mould having a collapsible core, in such a form that the moulded closure comprises the cap with the integral closing member and the ring member, connected by a hinge and guarantee connection connected to the cap, and axially spaced relative to the cap, the hinge is located at a periphery of the cap, and the closure is made having a coupling part, whereby the guarantee connection is formed generally flush with exterior surfaces of the cap and ring members and the container is provided with a coupling part that cooperates therewith. 6. The method of claim 5, wherein the ring member has an internal circumferential snap edge, that the container is provided with a circumferential groove around the opening, adapted to the snap edge, and that the moulded closure is pressed with its ring member onto the container so that the snap edge is pressed to snap into the circumferential groove. 7. The method of claim 5, wherein the guarantee connection is made so that it is clear whether the guarantee connection has been broken or not. 8. The method of claim 5, wherein the hinge is made in a radially indented portion of the cap. 9. The method of claim 8, wherein the indented portion is outwardly concave. 10. The method of claim 1, using the collapsible core to divide the mould chamber into two chamber parts, a first chamber part in which the cap is formed and a second chamber part in which the ring member is formed. 11. The method of claim 10, wherein the collapsible core partly closes the first and second chamber parts off from one another, so that a mould section is formed between the chamber parts, in which mould section the hinge and guarantee connection is formed. 12. The method of claim 10, wherein the collapsible core fills the axial space between the cap and the ring member. 13. The method of claim 10, wherein the collapsible core is provided with a circumferential recess that forms a snap edge providing the connection between the ring member and the container. 14. The method of claim 5, using the collapsible core to divide the mould chamber into two chamber parts, a first chamber part in which the cap is formed and a second chamber part in which the ring member is formed. 15. The method of claim 14, wherein the collapsible core partly closes the first and second chamber parts off from one another, so that a mould section is formed between the chamber parts, in which mould section the hinge and guarantee connection is formed. 16. The method of claim 14, wherein the collapsible core fills the axial space between the cap and the ring member. 17. The method of claim 14, wherein the collapsible core is provided with a circumferential recess that forms a snap edge providing the connection between the ring member and the container. 18. The method of claim 1, further comprising the step of dividing the mould into two chamber parts, a first chamber part in which the cap is formed and a second chamber part in which the ring member is formed. 19. The method of claim 5, further comprising the step of dividing the mould into two chamber parts, a first chamber part in which the cap is formed and a second chamber part in which the ring member is formed.
