• a closure cap, the closure cap having a cap part and a body part, wherein the body part is provided with a recess for receiving the neck part of the squeeze bottle, and wherein the body part is provided with a top wall, that forms the bottom of the recess, wherein the top wall has an outside surface and an inside surface, and has a dispensing opening for dispensing contents from the squeeze bottle on an outside of the closure cap body part, and wherein the top wall is on the inside surface provided with a loop shaped attachment surface extending around the dispensing opening;
• a valve, the valve arranged in said recess of the closure cap body part adjacent to the top wall such that the valve closes the dispensing opening, wherein the valve is a flat flexible foil material, and wherein the valve has a loop shaped peripheral section that overlaps the loop shaped attachment surface of the closure cap body part, and wherein the valve has a central section located in the dispensing opening of the closure cap body part, wherein the central section is provided with at least one through slit, thus forming a resilient, flat, self-closing valve;
• a first induction element, the first induction element arranged in said recess of the closure cap body part for induction sealing the loop shaped peripheral section of the valve to the loop shaped attachment surface of the closure cap body part, wherein the first induction element has at least a loop shaped peripheral section that overlaps with the loop shaped peripheral section of the valve and the loop shaped attachment surface of the closure cap body part;
• a first separator element, the first separator element arranged in said recess of the closure cap body part adjacent the first induction element to enable separating the first induction element from an object located on an opposite side of the first separator element;
• and
• a second separator element,
• wherein the first and second separator elements are provided on opposite sides of the first induction element.
