Abstract

Claims (36)

1. Stopper for closing a dispensing opening of a container comprising:

a body element for closing the container and its dispensing opening, comprising a top face and a bottom face, wherein the bottom face is directed towards an inside of the container and contacts an upper side of the container and the top face is directed away from the inside of the container and wherein the top face and the bottom face are dimensioned to cover the upper edges of the container when viewed from above and thus fully close the container;

a moving element, which substantially covers the entire top face of the body element, wherein the moving element is slidingly movable in a linear direction relative to the body element from an initial position in which the moving element does not extend beyond an outer extension of the top face in a plane of the top face of the body element, to an opening position wherein the moving element is slidingly moved relative to the body element to extend at least partly beyond the outer extension of the top face of the body element in the plane of the body element, wherein the moving element comprises in the open position, a gripping surface for a user to remove the body element from the dispensing opening, and wherein

the moving element substantially covers the top face of the body element when in the initial position.

2. Stopper according to claim 1 , wherein the body element further comprises a desiccant chamber situated at the bottom face of the body element, wherein the body element is made at least partly from a material selected from the group consisting of a desiccant material, an oxygen absorber and a gas absorber.

3. Stopper according to claim 1 , wherein the top face of the body element has dimensions smaller than, or equal to, outer dimensions of the container in the plane of the top face of the body element and wherein the moving element has dimensions smaller than or equal to the dimensions of the top face of the body element in the plane of the top face of the body element and to the container at a position in which the body element is connected to the container and wherein the body element does not extend beyond the plane defined by the moving element in a direction perpendicular to a plane defined by the moving element.

4. Stopper according to claim 1 , wherein the moving element is mounted to the top face of the body element by a positive locking rail element to allow movement of the moving element from the initial position to the opening position and wherein the moving element is mounted to the body element by mounting means situated at a bottom face of the moving element.

5. Stopper according to claim 1 , wherein the moving element is spring-biased towards the initial position, by a spring element which is integrally moulded with the moving element in the same plane as the moving element and is hinged to the moving element by a foil hinge.

6. Stopper according to claim 5 , wherein the spring element is associated with the moving element, and is situated in a recess of the moving element.

7. Stopper for closing a dispensing opening of a container comprising:

a body element for closing the dispensing opening, comprising a top face and a bottom face, wherein the bottom face is directed towards an inside of the container;

a moving element, on the top face of the body element, wherein the moving element is movable relative to the body element from an initial position in which the moving element does not extend beyond an outer extension of the top face in a plane of the top face of the body element, to an opening position wherein the moving element is moved relative to the body element to extend at least partly beyond the outer extension of the top face of the body element in the plane of the body element,

wherein the moving element comprises in the open position, a gripping surface for a user to remove the body element from the dispensing opening,

wherein the moving element substantially covers the top face of the body element when in the initial position,

wherein the moving element is spring-biased towards the initial position, by a spring element which is integrally moulded with the moving element in the same plane as the moving element and is hinged to the moving element by a foil hinge, and

wherein the moving element further comprises a recessed portion including a positive locking element to movably connect the moving element with the body element, wherein the recessed portion is dimensioned to receive the spring element.

8. Stopper for closing a dispensing opening of a container comprising:

a body element for closing the dispensing opening, comprising a top face and a bottom face, wherein the bottom face is directed towards an inside of the container;

a moving element, on the top face of the body element, wherein the moving element is movable relative to the body element from an initial position in which the moving element does not extend beyond an outer extension of the top face in a plane of the top face of the body element, to an opening position wherein the moving element is moved relative to the body element to extend at least partly beyond the outer extension of the top face of the body element in the plane of the body element,

wherein the moving element comprises in the open position, a gripping surface for a user to remove the body element from the dispensing opening, and

wherein the moving element substantially covers the top face of the body element when in the initial position, and

further comprising a tamper-evident member which prohibits movement of the moving element from the initial position to the opening position, wherein the tamper-evident member is removable by a user, and wherein the tamper-evident member extends above the top face of the body element and is integrally moulded with the body element.

9. Stopper according to claim 1 further comprising a skirt which when inserted into the container defines a dispensing opening, wherein the body element is insertable into the skirt in order to close the dispensing opening, and wherein the skirt comprises a flow reducer to reduce the flow of products to be dispensed through the dispensing opening.

10. Stopper according to claim 9 , wherein the body element is hinged to the container by a foil hinge hinged to the skirt.

11. Stopper according to claim 1 , wherein the top surface of the moving element further comprises a hot-die print, a hot stamp print, a serigraphy, a tampo print, an in-mould print, or an engraving of the mold.

12. Stopper according to claim 1 , wherein the moving element is slidingly movable in a linear rotational direction from the initial position to the opening position.

13. Method for manufacturing the stopper of claim 1 comprising

moulding the moving element including a spring element, wherein the spring element is moulded in a plane of the moving element;

folding the moving element below the moving element; and

mounting the moving element to the body element.

14. Stopper of claim 1 wherein the body element is made at least partially of a material selected from the group consisting of a resin and a desiccant, a resin and an oxygen absorber and a resin and a gas absorber.

15. Stopper of claim 4 wherein the positive locking rail element comprises a dovetail positive lock.

16. Stopper of claim 6 wherein the composition of the spring element is different from the composition of the moving element.

17. Stopper of claim 7 wherein a clip element is provided in the recessed portion which maintains the spring element in its active position and blocks the moving movement of the moving element in one direction.

18. Stopper of claim 9 wherein the skirt further comprises a material selected from the group consisting of a desiccant material, an oxygen absorber and a gas absorber.

19. Stopper of claim 9 wherein the skirt further comprises a material selected from the group consisting of a resin and a desiccant material, a resin and an oxygen absorber, and a resin and a gas absorber.
