[0052] Only those elements required in order to understand the invention have been depicted. In order to facilitate interpretation of the drawings, the same elements are labeled with the same references across all the figures.

[0053] It will be noted that, in this document, the terms horizontal, vertical, lower, upper, top, bottom, front, rear, longitudinal and transverse used to describe the cooking vessel refer to this cooking vessel when in use, when sitting flat on a worktop or heating appliance.

[0054] In a first embodiment shown in FIGS. 1 to 3, a cooking vessel 1a, which is a saucepan, comprises a body 2a that is 20 centimeters in diameter with a side wall 3a and a handle 4. The body 2a is made by stamping an aluminum disk. The handle 4 comprises a gripping part 5 and a connecting piece 10. The connecting piece 10 is attached to the side wall 3a. The connecting piece 10 has a radial portion 11 that extends radially relative to the side wall 3a, sloping upward relative to a substantially horizontal plane parallel to the plane on which the body 2a rests. The radial portion 11 forms an angle ? equal to 25? with a horizontal plane, in a vertical cross-section plane. The gripping part 5 is assembled to the radial portion 11 of the connecting piece 10 by overmolding.

[0055] The connecting piece 10 comprises an axial portion 14 that extends parallel to the side wall 3a in a substantially vertical manner. The axial portion 14 of the connecting piece 10 is attached to the side wall 3a by two rivets 20, 21 arranged in two parallel horizontal planes H1, H2. The two parallel horizontal planes H1, H2 are separated by a distance D equal to 15 millimeters (FIG. 2). The handle 4 comprises a vertical plane of symmetry PS. The two rivets 20, 21 are arranged in the vertical plane of symmetry PS (FIG. 2). Each rivet 20, 21 comprises a head 22, 23 arranged inside the body 2a of the cooking vessel 1a (FIG. 3) and a cap 24, 25 extending outwards from the body 2a of the cooking vessel 1a, radially to the side wall 3a. The cap 24, 25 is the result of crimping the free end of the rivet 20, 21, opposite the head 22, 23, using a riveting tool, once the rivet 20, 21 has been assembled on the body 2a and the connecting piece 10. Each rivet 20, 21 comprises a barrel 26, 27 with a diameter equal to 4 millimeters.

[0056] The connecting piece 10 is made from a stainless-steel strip with a thickness equal to 3 millimeters and a width L equal to 25 millimeters. Thus, the axial portion 14 extends downwards and to either side of the vertical plane of symmetry PS to give a width L equal to 25 millimeters. In a horizontal cross-section plane, perpendicular to the plane of symmetry PS, the axial portion 14 of the connecting piece 10 has an outer surface in the shape of a circular arc with a radius R equal to 10 centimeters (FIG. 3).

[0057] The axial portion 14 has two lateral edges 16, 17, each with an outer rim 18, 19 facing the body 2a. As the radius R of the axial portion 14 is equal to the radius of the body 2a, there is no clearance Ja between the outer surface 15 of the axial portion 14 and the body 2a after assembly. The outer surface 15 rests on the body 2a on a contact surface SCa which, in a horizontal cross-section plane, has a contact width LCa equal to the width L of the axial portion 14.

[0058] The connecting piece 10 comprises a radial portion 11 that extends radially relative to the side wall 3a from a junction end 29 (FIG. 2) with the axial portion 14, the end 29 being arranged immediately adjacent to an upper edge 7a of the cooking vessel 1a. The side wall 3a is extended upwards by an outwardly curved portion 6a. The junction end 29 is arranged directly under the curved portion 6a.

[0059] In a second embodiment shown in FIG. 4, a cooking vessel 1b, which is also a saucepan, comprises a body 2b that is 16 centimeters in diameter with a side wall 3b and the handle 4. The axial portion 14 of the connecting piece 10 is attached to the side wall 3b by the two rivets 20, 21, in the same way as for the cooking vessel 1a. As the radius R of the axial portion 14 is greater than the radius of the body 2b, there is a clearance Jb between each outer edge 18, 19 and the body 2b after assembly. The outer surface 15 of the axial portion 14 rests on the body 2b on a contact surface SCb which has, in a horizontal cross-section plane, a contact width LCb greater than half the width L of the axial portion 14. This is made possible by the force exerted by the two rivets 20, 21 on the axial portion 14 of the body 2b. In fact, once the rivets 20, 21 have been crimped, the side wall 3b of the body 2b is slightly deformed to increase the contact surface SCb. Such a contact surface SCb between the axial portion 14 and the body 3b [sic: 2b] is sufficient to ensure the lasting attachment of a small-diameter saucepan with a low filling capacity. Low filling capacity leads to limited stress when the cooking vessel is handled.

[0060] In a third embodiment shown in FIG. 5, a cooking vessel 1c, which is also a saucepan, comprises a body 2c that is 28 centimeters in diameter with a side wall 3c and the handle 4. The axial portion 14 of the connecting piece 10 is attached to the side wall 3c by the two rivets 20, 21, in the same way as for the cooking vessel 1a. As the radius R of the axial portion 14 is less than the radius of the body 2c, there is a clearance Jc between the outer surface 15 of the axial portion 14 and the body 2c, prior to assembly in the plane of symmetry PS. The outer surface 15 of the axial portion 14 rests on the body 2c on a contact surface SCc which, in a horizontal cross-section plane, has a contact width LCc. Before crimping the two rivets 20, 21, a force is applied to the axial portion 14 and to the body 2c to reduce or eliminate the clearance Jc. Thus, once the rivets 20, 21 have been crimped, the side wall 3c of the body 2c and the axial portion 14 are slightly deformed to increase the contact surface SCc so that the contact width LCc is almost equal to the width L of the axial portion 14. Such a contact surface SCc between the outer surface 15 of the axial portion 14 and the body 2c is necessary to ensure the lasting attachment of a large-diameter saucepan with a high filling capacity.

[0061] As shown in FIG. 6, a cooking vessel 1d, which is a saucepan, comprising a body 2d 18 centimeters in diameter with a side wall 3d and a handle 4. The side wall 3d is extended upwards by an outwardly curved portion 6d. The connecting piece 10 attached to the body 3d comprises the radial portion 11 that extends radially relative to the side wall 3d from the junction end 29. The junction end 29 of the handle 4 is arranged directly under the curved portion 6d, immediately adjacent to an upper edge 7d of the cooking vessel 1d. The radial portion 11 extends radially relative to the side wall 3d, sloping upward relative to a substantially horizontal plane parallel to the plane on which the body 2d rests. The radial portion 11 forms an angle ? equal to 25? with a horizontal plane, in a vertical cross-section plane. The cooking vessel 1d is stored by stacking it in the cooking vessel 1a which comprises the body 2a that is 20 centimeters in diameter with a side wall 3a. The side wall 3a and the side wall 3d have the same height h.

[0062] In this way, the cooking vessels 1a, 1b, 1c, 1d fitted with the same handle 4 have a secure and lasting riveted attachment of the handle 4.

[0063] Of course, the invention is in no way limited to the embodiment described and illustrated, since this embodiment was only provided by way of example. Changes can still be made, particularly with regard to the constitution of the various elements or by substituting technical equivalents, without departing from the scope of protection of the invention.

[0064] Thus, in a non-illustrated variant, the handle 4 comprises a short gripping part forming a lug with a central opening, and the radial part is in the shape of a U arranged around half of the periphery of the central opening.
