Abstract

The invention provides a cooking utensil for cooking food under pressure having a vessel, a lid, and a bayonet-fitting locking system comprising first and second series of locking projections, said utensil includes a lid subassembly that includes said lid and a support attached in pivotable manner to said lid, said lid subassembly and said vessel being configured to be associated with each other in a first arrangement in which the lid overlies the vessel, and a second arrangement obtained by moving said lid subassembly downwards until said first series of projections are lower than said second series of projections, said support and said vessel being provided respectively with complementary first and second guide elements that are configured to co-operate mutually whenever said lid subassembly and said vessel are associated with each other in said first arrangement.

First claim

The invention claimed is:

1. A cooking utensil for cooking food under pressure comprising:
a vessel;
a lid;
a bayonet-fitting locking system comprising a first series and a second series of locking projections integral respectively with the lid and with the vessel;
a lid subassembly that comprises said lid and a support attached to said lid in such a manner that said lid can pivot relative to said support, said lid subassembly and said vessel being configured to associate with each other in at least a first arrangement in which the lid overlies the vessel so that said first series of projections are significantly higher than said second series of projections, and a second arrangement obtained from said first arrangement by moving said lid subassembly downwards until said first series of projections are significantly lower than said second series of projections, said support and said vessel also being provided respectively with complementary first and second guide elements that are configured to co-operate mutually whenever said lid subassembly and said vessel are associated with each other in said first arrangement in order to guide said lid subassembly as it moves downwards; and
a first positioning element that is carried by said support and that is configured to interact mechanically with a complementary second positioning element carried by the vessel, when said lid subassembly and said vessel are associated with each other in said second arrangement, so as to lock a relative angular positioning of the support and of the vessel in a horizontal plane.

2. The cooking utensil according to claim 1 , wherein said support is attached to said lid such that said lid can pivot relative to said support about a central vertical axis, said downward movement being a movement in translation parallel to said central vertical axis.

3. The cooking utensil according to claim 1 , wherein said complementary first and second guide elements are configured to guide said lid subassembly substantially continuously as it moves downwards until said second arrangement is obtained.

4. The cooking utensil according to claim 1 , wherein said second arrangement allows the lid to pivot relative to the support to bring said first series of projections under said second series of projections into locking correspondence.

5. The cooking utensil according to claim 1 , wherein said support extends radially beyond the lid to form said first guide element.

6. The cooking utensil according to claim 1 , wherein said lid comprises:
a disk-shaped lid element; and
an annular band that extends between a first annular edge integral with the disk-shaped lid element and a free second annular edge,
wherein said vessel being locally surrounded by the free second annular edge when said lid subassembly and said vessel are associated with each other in said second arrangement, while, when said lid subassembly and said vessel are associated with each other in said first arrangement, said free second annular edge is higher than the vessel and does not surround said vessel.

7. The cooking utensil according to claim 6 , characterized in that wherein said first series of projections are carried by said annular band.

8. The cooking utensil according to claim 1 , wherein said co-operation between said first and second guide elements for guiding said lid subassembly as it moves downwards is co-operation of a male/female type.

9. The cooking utensil according to claim 8 , wherein said first and second guide elements respectively have a male shaped portion and a female shaped portion that are complementary to each other.

10. The cooking utensil according to claim 9 , wherein said female shaped portion forms a recess defined by at least a bottom from which a side wall extends vertically between a bottom edge and a top edge, said recess being configured to receive said male shaped portion by downward vertical insertion.

11. The cooking utensil according to claim 9 , wherein said male shaped portion extends vertically between a top edge and a bottom edge.

12. The cooking utensil according to claim 10 , wherein when said lid subassembly and said vessel are associated with each other in said first arrangement, said male shaped portion is inserted into said recess in such a manner that the bottom edge of the male shaped portion is lower than the top edge of said side wall of said recess and is separated vertically from the bottom of the recess by a first height.

13. The cooking utensil according to claim 12 , wherein, when said lid subassembly and said vessel are associated with each other in said second arrangement, said male shaped portion is inserted in said recess such that the bottom edge of the male shaped portion is lower than the top edge of said side wall of said recess and is separated vertically from the bottom by a second height less than said first height.

14. The cooking utensil according to claim 11 , wherein said support comprises a top portion that is mounted above the lid and that extends radially beyond said lid so as to be extended by a vertical dropped edge that forms said male shaped portion.

15. The cooking utensil according to claim 10 , wherein said first positioning element is formed by a notch provided in said vertical dropped edge, while said second positioning element is formed by a rib provided in the recess.

16. The cooking utensil according to claim 1 , wherein said vessel is provided with a handle that carries said second guide element.

17. The cooking utensil according to claim 16 , wherein said handle has a graspable portion that is shaped to be capable of being taken hold of manually in order to enable the vessel to be manipulated via it, and a fastening portion that interconnects said vessel and said graspable portion.

18. The cooking utensil according to claim 10 , wherein said side wall of said recess is formed by said graspable portion.

19. The cooking utensil according to claim 1 , wherein said lid subassembly comprises a sealing gasket carried by the lid and configured to be interposed between the lid and the vessel, said lid subassembly and said vessel being configured so that, when said lid subassembly and said vessel are associated with each other in said second arrangement, said lid subassembly rests and bears directly against the vessel in such a manner as to maintain a vertical spacing between said first and second guide elements, so that said first guide element does not bear vertically on said second guide element.

20. The cooking utensil according to claim 1 , further comprising:
a control member for controlling the bayonet-fitting locking system, which control member is configured to be capable of being moved manually relative to the support; and,
a transformation device for transforming said manual movement of the control member into pivoting of the lid relative to the support.

21. The cooking utensil according to claim 20 , wherein said control member is mounted to pivot relative to said support about a radial axis of pivoting that is perpendicular to said central vertical axis.

22. The cooking utensil according to claim 1 , wherein the cooking utensil is configured to be subjected to an external heat source.
