Closure cap for a fluid container and method for the fabrication
Closure cap ( 1 ) for a fluid container ( 30 ), which has a receiver ( 31 ), at which an applicator body ( 32 ) is movably supported, wherein the closure cap has a sealing element for contacting the receiver and/or the applicator body and has a cap base body ( 10 ) with an axial support ( 20, 20′ ), and wherein the sealing element and at least a part of the support are connected to each other by material bond.
1. Method for the fabrication of a closure cap for a fluid container, which has a receiver, at which an applicator body is moveably supported, wherein the closure cap has a ring-disk-shaped sealing element with a ring-shaped flange area for engaging a fluid gap between the applicator body and the receiver and has a cap base body with an axial support,
wherein the ring-disk-shaped sealing element and at least a part of the axial support are directly connected to each other by material bond without the use of adhesive,
during a master-forming of the ring-disk-shaped sealing element and/or the at least one part of the axial support, by injection into one another or by injection onto each other, and the axial support is a multipart axial support, which has a support base body, which is connected to the cap base body, and a connection part made from another material than the support base body, to which connection part the ring-disk-shaped sealing element is connected by material bond.
2. Closure cap for a fluid container, which has a receiver, at which an applicator body is supported moveably, wherein the closure cap has a ring-disk-shaped sealing element with a ring-shaped flange area for engaging a fluid gap between the applicator body and the receiver and has a cap base body with an axial support, and,
wherein the ring-disk-shaped sealing element and at least a part of the axial support are directly connected to each other by material bond without the use of adhesive,
during a master-forming of the ring-disk-shaped sealing element and/or the at least one part of the axial support, by injection into one another or by injection onto each other, and the axial support is a multipart axial support, which has a support base body, which is connected to the cap base body, and a connection part made from another material than the support base body, to which connection part the ring-disk-shaped sealing element is connected by material bond.
3. Closure cap according to claim 2 , wherein the axial support is permanently connected with the cap base body, and formed integral with the same.
4. Closure cap according to claim 2 , wherein the sealing element comprises at least one of thermoplastic elastomer (TPE) and/or silicone.
5. Closure cap according to claim 2 , wherein the axial support comprises polyoxymethylene (POM) or polypropylene (PP).
6. Closure cap according to claim 2 , wherein the axial support is elastically deformed when the closure cap is in the closed position.
7. Closure cap according to claim 2 , wherein the ring-disk-shaped sealing element or the axial support has a recess located on a contact surface and the other one of the ring-disk-shaped sealing element and the axial support has a recess configured to receive a connecting element received therein.
8. Closure cap according to claim 2 , wherein the closure cap has an axial securing means for the applicator body, at which the axial support is mounted.
9. Closure cap according to claim 2 , wherein the closure cap is removably mountable on the fluid container or the receiver.
10. Closure cap for a fluid container, which has a receiver, at which an applicator body is supported moveably, wherein the closure cap has a ring-disk-shaped sealing element with a ring-shaped flange area for engaging a fluid gap between the applicator body and the receiver and has a cap base body with an axial support, and wherein the ring-disk-shaped sealing element and at least a part of the axial support are connected to each other by material bond, wherein:
the axial support is permanently connected with the cap base body, and formed integral with the same;
the ring-disk-shaped sealing element comprises at least one of thermoplastic elastomer (TPE) and silicone;
the axial support comprises at least one of thermoplastic, in particular polyoxymethylene (POM) and polypropylene (PP);
the axial support is elastically deformed when the closure cap is in the closed position;
the ring-disk-shaped sealing element is formed, at least substantially, disk-shaped or has a flange area for engaging a fluid gap between the applicator body and the receiver;
at least one of the ring-disk-shaped sealing element or the axial support has a recess located on a contact surface and the other one of the ring-disk-shaped sealing element and the axial support has a recess configured to receive a connecting element therein;
the closure cap has an axial securing means for the applicator body, at which the axial support is mounted; and the closure cap is removably mountable on the fluid container or the receiver.
11. Closure cap according to claim 2 , wherein the closure cap has an axis of symmetry about which the ring-shaped flange area, the axial support, and the ring-disk-shaped sealing element are symmetrically disposed, and wherein the axial support is comprised at least of a first part which extends substantially perpendicularly to the axis of symmetry of the closure cap and a second part which extends substantially in parallel to the axis of symmetry of the closure cap.
