Description

Technical Field

[0001] The present invention relates to the technical field of lids for cooking vessels for preparing and / or cooking food.

[0002] The invention relates more particularly to a cover of the above-mentioned type comprising a glass element.

[0003] The invention relates particularly, but not exclusively, to a cover for a working container of an electrical appliance for preparing food, either heated or non-heated. Background Art

[0004] Document FR3002426 discloses a cover for a working container of a multifunctional food preparation appliance, the cover comprising a lower ring and a glass member, the glass member being carried by the lower ring. However, the glass member is held by a metal cover adapted to be deformed so that the lower ring and the glass member are connected as one by compression. Such assembly is difficult to achieve. Summary of the invention

[0005] The object of the present invention is to provide a cover of the above-mentioned type, the construction of which is easier to realize.

[0006] This object is achieved with a cover for a cooking vessel, in particular a working vessel for a cooking preparation appliance, comprising: an annular housing defining an opening and having an inner wall, a glass having a peripheral edge, an annular joint mounted on said peripheral edge, and an annular element, said annular housing being assembled with said annular element to retain said annular joint, characterized in that said inner wall has upper retaining stops distributed around said opening, and said annular housing and / or said annular element are elastically deformable to place said annular element against said annular joint in said annular housing, said annular element bearing against said upper retaining stops when said annular element is placed against said annular joint in said annular housing. These arrangements allow obtaining a cover comprising a glass having an annular joint, wherein the annular joint is retained between the annular housing and the annular element, with good sealing between the annular element and the annular joint. These arrangements allow obtaining a simple, reliable and economical retention of the glass. The annular element can be placed in the annular housing by a simple axial displacement.

[0007] Advantageously, the upper retaining stops are arranged at different heights on the inner wall. This arrangement allows facilitating the implantation of the upper retaining stops.

[0008] According to one embodiment, the annular element comprises an annular body from which extends a lower tongue distributed around the annular body.

[0009] Furthermore advantageously, when the annular element is placed in the annular housing against the annular joint, the annular body and the lower tongue bear against the upper retaining stop.

[0010] Advantageously, the cover comprises an annular sealing element comprising a joint seat ring and a sealing joint, the sealing joint being arranged to bear on the upper edge of the working container of the cooking preparation appliance, the joint seat ring carrying the sealing joint. If necessary, the sealing joint can be removed relative to the joint seat ring. Alternatively, the sealing joint can be overmolded, in particular, on the joint seat ring.

[0011] It is also advantageous if the joint race is mounted freely rotatably below the annular element.

[0012] Advantageously, the cap comprises a joint seat ring which is freely rotatably mounted below the annular element.This arrangement allows the cap to be rotationally locked on the container, in particular by using a bayonet locking device.

[0013] Advantageously, the lower tongue has an inner profile, and the joint seat ring is held under the annular element by the inner profile. This arrangement allows for easy placement of the joint seat ring.

[0014] Advantageously, the joint seat ring carries the sealing joint. If necessary, the sealing joint can be removed relative to the joint seat ring. Alternatively, the sealing joint can be especially overmolded on the joint seat ring.

[0015] Advantageously, the annular joint comprises a lower ring which is supported inside the joint seat ring. This arrangement allows preventing food from entering between the glass and the joint seat ring.

[0016] Advantageously still further, the annular body has a channel in which extends a rod carried by the inner wall of the annular housing. This arrangement allows the annular body to be prevented from rotating relative to the annular housing.

[0017] Advantageously, the rod is ultrasonically welded to the annular housing and the annular element. This arrangement allows a durable assembly of the cover to be obtained.

[0018] Advantageously also, the inner wall has at least one lower bearing stop against which the annular element bearing against the upper retaining stop rests. This arrangement allows to avoid excessive squeezing of the annular joint.

[0019] In a further advantageous manner, at least one lower bearing stop is annular. This arrangement allows for a better distribution of the pressure exerted on the annular joint.

[0020] Advantageously still, the cover comprises at least one handle from the annular housing.This embodiment is very suitable for annular housings made of plastic.

[0021] Advantageously, the cover comprises two opposing handles from the annular housing. This arrangement allows easy handling of the cover.

[0022] Advantageously, the annular cover comprises an inner tongue for bayonet locking. This arrangement allows a cover to be realized in a simple and economical manner, which can be bayoneted to a container, such as a working container of an electrical food preparation device, in particular a working container of a heating-type food preparation device.

DETAILED DESCRIPTION

[0032] Figure 7 and Figure 8The cover 1 for a cooking vessel shown is intended to be used with a working vessel of an electrical food preparation device, such as, in particular, a cooking robot (not shown in the figures) that performs heating.

[0033] As in Figures 1 to 8 As can be seen, cover 1 includes: Figure 1 The annular outer cover 10 shown, Figure 2 The glass element 20 and the annular joint 25 are shown, and Figure 3 The annular element 30 is shown.

[0034] As in Figure 1 As can be seen in the figure, the annular outer cover 10 defines an opening 11. The annular outer cover 10 has an inner wall 12. More specifically, in the embodiment shown in the figure, the opening 11 is defined by the upper end of the inner wall 12.

[0035] The inner wall 12 has a first upper retaining stop 13 and a second upper retaining stop 14 arranged as a retaining annular element. The upper retaining stops are distributed around the opening 11. More specifically, in the embodiment shown in the figures, the first upper retaining stop 13 and the second upper retaining stop 14 are arranged at different heights on the inner wall 12.

[0036] Figure 2 An annular joint 25 is shown mounted on the glass member 20. Figure 8 As can be seen in the figure, the glass piece 20 has a peripheral edge 21. The annular joint 25 is preferably made of an elastomeric material, in particular silicon. The annular joint 25 is mounted on the peripheral edge 21. If necessary, the annular joint 25 can be overmolded on the glass piece 20.

[0037] More specifically, in the embodiment shown in the figures, the glass member 20 is annular and has a central channel 22. Figure 2 As can be seen in Figure 6 and Figure 7 As can be seen in the figure, the central protrusion 23 is mounted on the glass piece 20. The central protrusion 23 includes a housing for receiving a removable plug 24. The housing is preferably through-going. If necessary, in addition to or instead of the housing, a steam discharge channel can be configured in the glass piece 20 and / or the central protrusion 23.

[0038] As in Figure 3 and Figure 6 As can be seen in the figure, the annular element 30 comprises an annular body 31. More specifically, in the embodiment shown in the figure, a lower tongue 32 extends from the annular body 31. The lower tongue 32 is distributed around the annular body 31. The number of the lower tongue 32 is, for example, four.

[0039] according to Figure 4 , Figure 5 , Figure 7 and Figure 8 In the preferred embodiment shown, the cover 1 comprises an annular sealing element comprising Figure 4 The joint seat ring 40 and the sealing joint 50 are shown. The sealing joint 50 is preferably made of an elastomeric material, in particular silicone. The sealing joint 50 is arranged to be supported on the upper edge of the working container of the cooking preparation appliance. The joint seat ring 40 carries the sealing joint 50, such as Figure 8 As shown in Figure 4 As can be seen in the figure, the joint seat ring 40 has an outer groove 41. Ribs 42 are formed at the bottom of the outer groove 41 to minimize the contact between the joint seat ring 40 and the sealing joint 50. If necessary, the joint seat ring 40 can be mounted freely rotatably below the annular element 30. As an alternative or in addition, the sealing joint 50 can be mounted freely rotatably relative to the joint seat ring 40.

[0040] As in Figure 3 , Figure 6 , Figure 7 and Figure 8 As can be seen in the figure, the lower tongue 32 has an inner formation 33. The joint seat ring 40 is retained below the ring element 30 by the inner formation 33. If desired, at least one of the inner formations 33, and preferably each of the inner formations 33, can have a chamfered lower surface to facilitate the placement of the joint seat ring 40 in the ring element 30, as in Figure 8 Visible in.

[0041] As in Figure 6 and Figure 7 As can be seen in FIG. 1 , the cap 1 comprises two opposite handles 60 coming from the annular housing 10 . As a variant, the cap 1 may in particular comprise at least one handle 60 coming from the annular housing 10 .

[0042] More specifically, in the embodiment shown in the figures, the annular outer cover 10 comprises an inner tongue 18 for bayonet locking, as in Figure 1 , Figure 6 and Figure 7 An inner tongue 18 for bayonet locking is provided for engagement with a working container of the electrical food preparation device.

[0043] The annular housing 10 is assembled with the annular element 30 to hold the annular joint 25. To this end, the annular housing 10 and / or the annular element 30 can be elastically deformed to place the annular element 30 against the annular joint 25 in the annular housing 10. When the annular element 30 is placed against the annular joint 25 in the annular housing 10, the annular element 30 bears against the first upper retaining stop 13 and the second upper retaining stop 14. Figure 8 shown.

[0044] like Figure 8As shown, the annular joint 25 is visible on the upper part of the cover 1 between the annular cover 10 and the glass 20. The annular cover 10 covers an annular element 30 mounted inside the inner wall 12.

[0045] As in Figure 1 As can be seen in the figure, the rod 16 is carried by the inner wall 12 of the annular housing 10. The rod 16 can come from the inner wall 12. In other words, the rod 16 and the inner wall 12 can be formed by the same component. If necessary, the rod 16 and the annular housing can be formed by the same component. Alternatively, the rod 16 can be fixed in particular in a housing of the inner wall 12.

[0046] As in Figure 3 As can be seen in FIG. 1 , the annular body 31 has channels 34. The number of channels 34 is, for example, four, which are offset relative to the lower tongue 32. Figure 6 As can be seen in the figure, the rod 16 extends in the channel 34. If necessary, the rod 16 can pass through the annular joint 25, for which purpose, the annular joint 25 can have other channels (not shown in the figure).

[0047] According to a preferred embodiment, the rods 16 are ultrasonically welded to the annular element 30. Alternatively, the rods 16 can be assembled to the annular element 30, in particular by hot air snap riveting, to fuse the apparent end of each rod 16 to the annular element 30. The annular element 30 and the rods 16 are made of polyamide, for example. Preferably, the rods 16 come from the annular housing 10, and the annular housing 10 is made of polyamide.

[0048] If necessary, at least one of the first upper retaining stopper 13 and the second upper retaining stopper 14, and preferably each of the first upper retaining stopper 13 and the second upper retaining stopper 14 may have a chamfered lower surface to facilitate placing the annular element 30 in the annular outer cover 10 so as to assemble the annular outer cover 10 with the annular element 30 to retain the annular joint 25.

[0049] More specifically, in the embodiment shown in the figures, when the annular element 30 is placed in the annular housing 10 against the annular joint 25, the annular body 31 and the lower tongue 32 bear against the first upper retaining stop 13 and the second upper retaining stop 14. Figure 8 As can be seen in FIG. 2 , the annular joint 25 comprises a lower ring 26 which is supported inside a joint seat ring 40 .

[0050] like Figure 8 As shown, the inner wall 12 has at least one lower bearing stop 15. The annular element 30 bearing against the first upper retaining stop 13 and the second upper retaining stop 14 also rests against the lower bearing stop 15. Preferably, the inner wall 12 has an annular lower bearing stop 15.

[0051] The cover 1 allows obtaining a large free surface for the glass 20 and is easy to assemble. To assemble the cover 1, the glass 20 carrying the annular joint 25 can be positioned inverted in the annular housing 10 which is itself inverted. The annular element 30, which is also inverted, is then placed in the inner wall 12 of the annular housing 10 through the channel 34 on the engagement rod 16. The annular element 30 then bears against the lower support stop 15 in an annular stop, which allows limiting or even avoiding penetration between the annular element 30 and the annular housing 10. The annular body 31 bears against the second upper retaining stop 14, and the lower tongue 32 bears against the first upper retaining stop 13. Thus, the annular element 30 and the annular housing 10 are connected in one piece by clamping. Ultrasonic welding at the rod 16 allows strengthening the assembly and making it non-detachable.

[0052] The invention is by no means limited to the described embodiments and their variants, but comprises numerous variations within the scope of the claims.
