Description

COOKING CONTAINER WITH A HANDLE SECURED BY TWO FLUSH RIVETS

[0001] The present invention relates to a cooking vessel having a riveted handle, in particular a frying pan, a saucepan, a sauté pan or a Dutch oven. State of the art

[0002] Document FR3121025 discloses a cooking vessel comprising a side wall and a handle. The handle comprises a connecting piece fixed to the side wall. The connecting piece comprises an axial portion which extends parallel to the side wall and which is fixed to the side wall by at least two rivets each comprising a riveting. The at least two rivets are arranged in at least two parallel horizontal planes H1, H2, separated by a distance D.

[0003] In this document, each rivet is prominent and protrudes from the connecting piece. Thus, when stacking a small diameter cooking vessel in a larger diameter cooking vessel, each rivet of the small diameter cooking vessel may come into contact with an internal face of the side wall of the larger diameter cooking vessel. This repeated contact may cause damage to the internal face, particularly when it has a surface treatment such as polishing or a coating.

[0004] In addition, when cleaning, each prominent punch constitutes an aggressive part which can damage cleaning utensils, for example a sponge.

[0005] The present invention aims to remedy these drawbacks.

[0006] The technical problem underlying the invention is to provide a cooking container which has a safe and durable construction over time.

[0007] Another object of the invention is to provide a cooking container which has a simple and economical design to implement.

[0008] To this end, the invention relates to a cooking container comprising a side wall and a handle, said handle comprising a connecting piece fixed to the side wall, said connecting piece comprising an axial portion which extends parallel to the side wall and which is fixed to the side wall by at least two rivets each comprising a riveting, the at least two rivets being arranged in at least two parallel horizontal planes H1, H2, separated by a distance D, characterized in that the axial portion comprises at least two holes for the passage of the at least two rivets, each hole comprising an entry chamfer in which the entire riveting of the rivet is housed.

[0009] By riveting, we understand the result of the operation of crimping a free end of the rivet, opposite a head, using a riveting tool, once the rivet is assembled on the cap.

[0010] By hole comprising an entry chamfer, we understand that the chamfer comprises a generator which can be a straight line but also a curved line, the generator defining a housing in which the entire riveting of the rivet is housed.

[0011] Thus, the axial portion has an outer face that does not have any portion of the riveting that protrudes. Accordingly, when stacking a small diameter cooking vessel in a larger diameter cooking vessel, the smooth outer face of the axial portion of the small diameter cooking vessel can come into contact with an inner face of the side wall of the larger diameter cooking vessel without damaging it.

[0012] The smooth outer face of the axial portion is particularly useful, especially at the lowest rivet which has to travel a significant distance when removing a small diameter cooking vessel from a larger diameter cooking vessel, with an increased risk of coming into contact with the inner face of the side wall of the larger diameter cooking vessel.

[0013] Advantageously, the axial portion has a thickness E and the chamfer extends over at least 25% of the thickness E.

[0014] Such an arrangement allows sufficient expansion of the riveting in the volume defined by the chamfer to obtain good mechanical strength of the rivet.

[0015] Preferably, the connecting piece is made from a stainless steel metal strip with a thickness E greater than 2 millimeters.

[0016] This means that the connecting piece is produced very economically.

[0017] Advantageously, the chamfer has an opening angle β greater than or equal to 90°.

[0018] Preferably, the riveting has a flat external surface.

[0019] Advantageously, each rivet comprises a barrel having a diameter less than or equal to 6 millimeters, preferably less than 4 millimeters.

[0020] Such a small barrel diameter allows simultaneous riveting of two rivets for a simple assembly process.

[0021] Preferably, the axial portion extends laterally to a vertical plane, perpendicular to the side wall, over a width L less than 30 millimeters, preferably less than 25 millimeters.

[0022] Thus, the at least two rivets are arranged in a superimposed manner to allow a narrow axial portion to be obtained which has a small width. Consequently, such a small axial portion makes it possible to make the handle compatible with the different sizes of cooking vessels in the same range.

[0023] Advantageously, the distance D is greater than 10 millimeters, preferably greater than 15 millimeters.

[0024] Thus, the at least two rivets are sufficiently spaced to obtain a fixing resistant to stresses when handling the cooking container.

[0025] Preferably, the connecting piece comprises a radial portion and a connecting portion connecting the axial portion to the radial portion, the radial portion extending radially relative to the side wall, above an upper edge of the cooking vessel.

[0026] Thus, when stacking a small diameter cooking vessel within a larger diameter cooking vessel, the small diameter cooking vessel may nest extensively until the radial portion comes close to the upper edge of the larger diameter cooking vessel.

[0027] The invention also relates to an assembly formed by at least two cooking containers comprising a side wall and a handle, each cooking container being as previously described.

[0028] The handle attachment system for each cooking vessel is particularly compact and allows a small diameter cooking vessel to be stacked inside a larger diameter cooking vessel, with the small diameter and the larger diameter being close, in particular of the order of two centimetres.

[0029] Advantageously, the axial portion of the connecting piece comprises an external face which has, in a horizontal transverse section plane, a shape of an arc of a circle with a radius R of between 7 and 12 centimetres, said external face bearing at least partially on the side wall.

[0030] Thus, such a radius is a good compromise so that the same axial portion can be fixed to each of the cooking containers of the same range having a circular shape, in particular a range of saucepans ranging from a diameter of 14 centimetres to a diameter of 28 centimetres.

[0031] Advantageously, the handle comprises a gripping part which is assembled on the connecting part by overmolding.

[0032] Advantageously, the radial portion extends radially relative to the side wall in an upwardly inclined manner, the radial portion forming with a horizontal plane, in a vertical section plane, an angle greater than 20°.

[0033] Thus, when stacking a small diameter cooking vessel within a larger diameter cooking vessel, the small diameter cooking vessel will be able to nest even more closely until the radial portion comes into contact with the upper edge of the larger diameter cooking vessel.

[0034] Advantageously, the cooking container is a frying pan, a saucepan, a sauté pan or a Dutch oven.

[0035] Advantageously, the cooking vessel comprises an internal surface which comprises a coating or surface treatment.

[0036] Advantageously, the cooking vessel comprises an internal surface made of aluminum, the internal surface comprising a non-stick coating.

[0037] Advantageously, the cooking vessel comprises an internal surface made of stainless steel, the internal surface being polished.

[0038] Advantageously, each side wall of the at least two cooking containers has an identical height h.

[0039] Thus, when stacking a small diameter cooking vessel within a larger diameter cooking vessel, the small diameter cooking vessel may lie flat within the larger diameter cooking vessel, with the radial portion of the small diameter cooking vessel being able to extend over the top edge of the larger diameter cooking vessel.

[0040] As a result, stacking stability is improved and the risk of damage to the larger diameter cooking vessel by the smaller diameter cooking vessel is greatly reduced. Brief description of the figures

[0041] The aims, aspects and advantages of the present invention will be better understood from the description given below of a particular embodiment of the invention presented by way of non-limiting example, with reference to the appended drawings in which:

[0042] This is a perspective view of a cooking container according to a particular embodiment of the invention, the cooking container being a saucepan with a diameter of 20 centimeters,

[0043] This is a partial sectional view along the vertical section plane II-II of the cooking vessel of the,

[0044] This is a partial sectional view along the horizontal section plane III-III of the cooking vessel of the,

[0045] Laest is a sectional view along the vertical section plane II-II of the cooking vessel of laet of a cooking vessel of smaller diameter, in particular a saucepan with a diameter of 18 centimetres, the two cooking vessels being stacked.

[0046] This is a partial sectional view along the horizontal section plane VV of the cooking vessels of the.

[0047] Only the elements necessary for understanding the invention have been shown. To facilitate reading of the drawings, the same elements bear the same references from one figure to another.

[0048] It should be noted that in this document, the terms "horizontal", "vertical", "lower", "upper", "top", "bottom", "front", "rear", "longitudinal", "transverse", used to describe the cooking vessel refer to this cooking vessel in use, when it rests flat on a work surface or a heating appliance.

[0049] In a first embodiment shown in Figures 1 to 3, a cooking container 1a which is a saucepan, comprises a cap 2a with a diameter of 20 centimeters provided with a side wall 3a and a handle 4. The cap 2a is produced by stamping an aluminum disc. The handle 4 comprises a gripping part 5 and a connecting piece 10. The connecting piece 10 is fixed to the side wall 3a. The connecting piece 10 comprises a radial portion 11 which extends radially relative to the side wall 3a, in an upwardly inclined manner relative to a substantially horizontal plane, parallel to the plane on which the cap 2a is placed. The radial portion 11 forms with a horizontal plane, in a vertical section plane, an angle α equal to 25°. The gripping part 5 is assembled on the radial portion 11 of the connecting piece 10 by overmolding.

[0050] The connecting piece 10 comprises an axial portion 14 which extends parallel to the side wall 3a in a substantially vertical manner. The connecting piece 10 comprises a connecting portion 12 arranged between the axial portion 14 and the radial portion 11. The axial portion 14 of the connecting piece 10 is fixed 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. The handle 4 comprises a vertical plane of symmetry PS. The two rivets 20, 21 are arranged in the vertical plane of symmetry PS (). Each rivet 20, 21 comprises a shaft 26, 27 having a diameter equal to 4 millimeters. Each rivet 20, 21 has a head 22, 23 arranged inside the cap 2a of the cooking container 1a () and a rivet 24, 25 arranged on the axial portion 14. The axial portion 14 has an external face 19.The axial portion 14 comprises two holes 15, 16 for the passage of the two rivets 20, 21. Each hole 15, 16 comprises an entry chamfer 17, 18 arranged on the side of the external face 19. The chamfer 17, 18 comprises a generatrix which is a straight line, the generatrix defining with the shank 26, 27 of the rivet 20, 21 an annular housing of triangular section. The chamfer 17, 18 is sized to receive the entirety of the riveting 24, 25 of the rivet 20, 21. The riveting 24, 25 is the result of the operation of crimping the free end of the rivet 20, 21, opposite the head 22, 23, using a riveting tool, once the rivet 20, 21 is assembled on the cap 2a and the connecting piece 10. The riveting tool has a flat end face which crushes the free end of the rivet 20, 21. Thus, the riveting 24, 25 has a flat external surface 28, 29, slightly set back by a few tenths of a millimeter from the external face 19 of the axial portion 14.

[0051] The connecting piece 10 is made from a stainless steel metal strip with a thickness E () equal to 3 millimeters and a width L equal to 25 millimeters. The chamfer 17, 18 extends over one millimeter, or 33% of the thickness E. The chamfer 17, 18 has an opening angle β () equal to 90°.

[0052] Thus, the axial portion 14 extends downwards and on either side of the vertical plane of symmetry PS to have a width L equal to 25 millimeters. In a horizontal section plane, perpendicular to the plane of symmetry PS, the external face 19 of the axial portion 14 of the connecting piece 10 has the shape of an arc of a circle with a radius R equal to 10 centimeters ().

[0053] The radial portion 11 extends radially relative to the side wall 3a from the connecting portion 12. The radial portion 11 is arranged above an upper edge 7a of the cooking vessel 1a. The side wall 3a is extended upwardly by an outwardly curved portion 6a. The connecting portion 12 is arranged in the immediate vicinity of the curved portion 6a.

[0054] As seen in Figures 4 and 5, a cooking vessel 1b which is a saucepan, comprising a cap 2b with a diameter of 18 centimeters provided with a side wall 3b and a handle 4. The side wall 3b is extended upwards by a portion 6b curved outwards. The connecting piece 10 fixed to the cap 3b comprises the radial portion 11 which extends radially relative to the side wall 3b from the connecting portion 12. The connecting portion 12 is arranged in the immediate vicinity of the curved portion 6b. The radial portion 11 is arranged above an upper edge 7b of the cooking vessel 1b. The radial portion 11 extends radially relative to the side wall 3d, in an upwardly inclined manner relative to a substantially horizontal plane, parallel to the laying plane of the cap 2b. The radial portion 11 forms with a horizontal plane, in a vertical section plane, an angle α equal to 25°.The cooking vessel 1b is stacked in the cooking vessel 1a which has the cap 2a with a diameter of 20 centimeters provided with the side wall 3a. The side wall 3a and the side wall 3d have the same height h.

[0055] As can be seen in the figure, the axial portion 14 provided with the riveting 24 fixed to the cooking container 1b is arranged opposite the internal face of the side wall 3a of the cooking container 1a. When stacking or unstacking the cooking container 1b in the cooking container 1a, the smooth external face 19 of the axial portion 14 of the cooking container 1b can come into contact with an internal face of the side wall 3a of the cooking container 1a without damaging it.

[0056] Of course, the invention is in no way limited to the embodiment described and illustrated, which has been given only as an example. Modifications remain possible, in particular from the point of view of the constitution of the various elements or by substitution of technical equivalents, without departing from the scope of protection of the invention.

[0057] Thus, in an alternative embodiment not illustrated, the chamfer comprises a generatrix which is an L-shaped line, the generatrix defining with the barrel of the rivet an annular housing of rectangular section in which the entire riveting of the rivet is housed.
