Definitions

• the present application relates to the field of pots, and in particular cosmetic pots.
• a pot of cosmetic product has a base, usually glass or plastic, that is to say a container surmounted by a neck whose diameter is close to the sectional dimensions of the base, to have a large opening .
• the base is closed by a lid, usually screwed on the neck.
• the lid is also generally equipped with a seal responsible for sealing the closure for good preservation of the contained product.
• a disadvantage lies in the fact that the thread of the thread present on the neck makes it necessary to have an open neck of the remainder of the base over a certain height and also a cover of a relatively large height; in other words the presence of the thread imposes dimensional constraints for the height of the neck and the thickness of the lid.
• the pot For a non-circular shaped pot whose base and lid have identical contours, the pot often has a stop that limits the angular travel of the lid relative to the base so as always to have a coincidence of shape between the base and the lid. The presence of the stop thus prevents screwing beyond, and therefore to compensate for a loss of tightness in case of crushing of the seal.
• document US2004 / 0067091 discloses a bottle, typically for nail polish, which allows closure by clipping of the cap on the container and an opening by pressing on at least one button acting on an elastic ring.
• a spring device further ensures a tight closure of the bottle to prevent overflow of the product it contains.
• Such a cap has the disadvantage of being particularly bulky, and in particular to generate a relatively large height to accommodate the device.

• the cover comprising a radial cam, the radial cam being defined by a profile forming at least one projecting active area,
• the attachment plate comprising:
• At least one attachment element mounted on the support and movable in translation relative thereto, the at least one attachment element comprising a claw and a cam follower, the cam follower being in contact with the radial cam of the cowl, the at least one latching member being configured to take at least one first position when the lid is in the rest position and a second position when the lid is in the open position, the second position being a position in which the cam follower of the latching member cooperates with the at least one active area projecting from the radial cam and in which the at least one fastening element, in second position, is translated relative to the first position, and

• a notch configured to form at least one longitudinal stop, that is to say in a vertical direction relative to the pot, so that it is impossible to pull the lid to open the pot without turning it so that the inner and outer parts pivot relative to each other to release the claw of a hooking element thus forming a hook, that is to say away from the neck so that it can be cleared of the notch.
• a rotation of the cover relative to the attachment plate induces a movement of the claw allowing it, for example, to disengage from the notch formed in the neck of the base.
• the lid is in the rest position, and no effort is applied to its various components. The wear of the lid is thus limited.
• the opening of the pot is achieved by the relative rotation of the outer cover and the inner plate, but any relative rotation between the inner plate and the neck of the base of the pot is very limited or even avoided, so that a seal may be present works mainly in compression, minimizing shear stresses, very present in the case of a pot with screwed lid.
• the seal can be made of an adherent material, that is to say which has low sliding qualities.
• the sealing is therefore easier to achieve with efficiency and a large choice of materials and / or embodiments is possible to achieve the seal.
• the pot is aesthetic because it is possible to dispense with threading at the neck. This eliminates the constraints of dimensions on the height of the neck and the thickness of the lid that imposed the presence of a thread.
• Such a lid is also aesthetic because no part of its mechanism, apart from possibly at least one claw, is visible to a user without resorting to disassembly of the lid.
• Such a hidden mechanism provides the lid an elegant shape.
• the cover also allows a large volume variability, which allows to achieve different sizes without being constrained by the size of the mechanism that includes, especially in height.
• the lid is easily adaptable to any existing pot for example and can also be re-adapted later to another pot, the same product or having a different capacity. This allows for example to customize the lid and to keep it during the use of different pots, whether pot of the same product, or different products, whatever their capacity.

• the projecting active area has for example a shape of bump or involute segment of a circle.
• the profile of the cam has a regular contour to ensure a smoother rotational movement of the mounting plate relative to the cover, smoothly.
• the cam is located towards the center of the cover. This produces a lever arm effect between the periphery of the lid and the area where the cam is located. Therefore, the torque that a user must apply between the base of the pot and the lid to cause relative rotation of the cap relative to the plate is low. In any case, the torque is lower than for a traditional screw cap where the torque applied by the user must overcome the friction between the cover and the neck which are located at the periphery of the cover.
• the at least one attachment element in second position is thus translated relative to the first position in a radial direction with respect to a center of rotation of the cam. Such displacement induced by the cam makes it easier to guarantee easy opening of the pot when the lid is used.
• the attachment plate is held oriented on the neck when the hood is rotated until the at least one claw disengages from the at least one notch of the neck.
• the pot is thus hermetically sealed and can be opened by a simple and quick gesture, in particular because such a lid can open the pot with a movement possibly less than or equal to about a quarter of a turn (90 °) or about 45 ° preferably, or less, for example about 15 ° or about 10 °.
