Abstract

A pot including a base and a lid, configured to adopt a closed position and an open position, that includes at least one locking strip positioned between a cover and a latching plate of the lid and fixed with respect to the cover, configured to adopt a locked position in which it presses against a rear wall of a latching element, thus holding a claw in a notch in a neck of the base, when the lid is in the closed position, and to adopt an unlocked position, in which the at least one locking strip is moved angularly with respect to its locked position and distant from the rear wall of the at least one latching element, when the lid is in the open position.

First claim

The invention claimed is:

1. Pot comprising:
a base comprising a container topped with a neck provided with a notch; and
a lid configured to close the base;
the lid being configured to adopt a closed position and an open position, the lid comprising:
a latching plate and a cover, the latching plate and the cover being mounted rotatably with respect to each other, the lid adopting the open position when the cover is turned with respect to the latching plate to the closed position;
at least one latching element provided with a claw;
the latching element being configured to adopt:
a first position with the claw engaged in the notch when the lid is in the closed position and the pot is closed; and
a second position in which the claw has been moved away from the neck with respect to the first position and is disengaged from the notch, when the lid is in the open position; and

a radial, eccentric double-acting slider and a guide stud configured to slide with respect to the slider between a first position and a second position;
the latching element being configured to adopt:
the first position when the guide stud is in the first position with respect to the slider;
the second position when the guide stud is in the second position with respect to the slider;

the lid further comprising at least one locking strip positioned between the cover and the latching plate and fixed with respect to the cover;
the at least one locking strip being configured to adopt:
a locked position in which the at least one locking strip presses against a rear wall of the at least one latching element, thereby holding the claw in the notch, when the lid is in the closed position; and
an unlocked position in which the at least one locking strip has been moved angularly with respect to the locked position and distant from the rear wall of the at least one latching element when the lid is in the open position.

2. Pot according to claim 1 , wherein:
the rear wall of the at least one latching element comprises a ramp, the ramp comprising:
a start of travel having a first thickness, and
an end of travel having a second thickness, the first thickness being less than the second thickness;
the start of travel being positioned angularly between the end of travel and the at least one locking strip in the unlocked position.

3. Pot according to claim 1 , wherein:
the cover comprises:
at least one protuberance comprising a summit and, along a perimeter portion of the cover on opposite sides of the summit, a ramp and a stop face;

the latching plate comprises:
at least one elastic leaf comprising a boss, the boss having a summit and, on opposite sides of the summit of the boss, a ramp and a stop face;

the summit of the at least one protuberance is angularly distant from the summit of the boss when the lid is in the open position; and
the stop face of the protuberance is configured to press against the stop face of the boss when the lid is in the closed position;
the summit of the protuberance is configured to move beyond the summit of the boss when the lid moves from the open position to the closed position and thereby forms a hard spot zone.

4. Pot according to claim 1 , wherein:
the neck comprises a recess forming an angular stop at least when the lid moves from the closed position to the open position;
the latching plate comprises at least one elastically deformable indexing tab, the indexing tab extending over a perimeter portion of the latching plate and comprising:
an embedded end embedded in a support of the latching plate;
a free end, opposite the embedded end;
an inner face and an outer face opposite the inner face;
the outer face comprising a rib extending along a perimeter portion of the latching plate and the free end being provided, on the inner face, with a spur; and

the cover comprises at least one pair of accompanying ribs parallel to each other, arranged at an angular distance “d” from each other;
in the closed position of the lid, one of the accompanying ribs of the pair presses on the rib of the indexing tab of the latching plate, holding the spur of the indexing tab anchored in the recess in the neck, in the open position of the lid, the two accompanying ribs of the pair being angularly distant from the rib of the indexing tab; and
at least one of the accompanying ribs of the pair is configured to slide on the rib of the indexing tab when the lid moves from the closed position to the open position.

5. Pot according to claim 1 , wherein:
the lid comprises a latching member, the latching member comprising a central frame;
the at least one latching element is connected to the central frame; and
at least one leaf spring connected to the central frame and the at least one leaf spring pressing against the at least one latching element and configured to push back the latching element.

6. Pot according to claim 1 , wherein:
the claw of the at least one latching element comprises a sloped face configured to engage with the neck of the base to compress a seal when the lid is in the closed position and the pot is closed.

7. Pot according to claim 1 , wherein:
the base comprises a shoulder provided with at least one ramp; and
the latching plate comprises at least one cavity with a complementary shape configured to engage with the at least one ramp.

8. Pot according to claim 1 , wherein:
the at least one latching element of the lid comprises four latching elements distributed every 90° around a perimeter of the lid;
each of the four latching elements comprises:
a claw;
a radial, eccentric double-acting slider and guide stud; and
a locking strip.

9. Pot according to claim 3 , wherein:
the at least one latching element of the lid comprises four latching elements distributed every 90° around a perimeter of the lid;
each of the four latching elements comprises:
a claw;
a radial, eccentric double-acting slider and guide stud;
a locking strip; and

the at least one elastic leaf of the latching plate comprises diametrically opposite at least two elastic leaves, each with a respective boss; and
the at least one protuberance of the cover comprises at least two protuberances corresponding to respective ones of the bosses of the at least two leaves.

10. Pot according to claim 4 , wherein:
the at least one latching element of the lid comprises four latching elements distributed every 90° around a perimeter of the lid;
each of the four latching elements comprises:
a claw;
a radial, eccentric double-acting slider and guide stud;
a locking strip; and

the at least one pair of accompanying ribs of the cover comprises at least two pairs of accompanying ribs; and
the at least one elastically deformable indexing tab of the latching plate comprises at least two pairs of accompanying elastically deformable indexing tabs.

11. Pot according to claim 5 , wherein:
the at least one latching element of the lid comprises four latching elements distributed every 90° around a perimeter of the lid;
each of the four latching elements comprises:
a claw;
a radial, eccentric double-acting slider and guide stud;
a locking strip; and

the at least one leaf spring connected to the central frame of the latching member comprises four leaf springs connected to the central frame of the latching member.
