    The lid comprises: a visible indicator of movable pressure between two positions indicating the existence and absence of pressure inside the pot, a locking mechanism of the lid in a closed position of the pot, an adjustable valve the steam outlet, and a manual selector for arrangement of the adjustable valve in different positions of steam outlet and the arrangement of the lid locking mechanism in a lid opening position.

    Field of application of the invention 20

    This invention is applicable in the field dedicated to the manufacture of kitchen containers and in particular pressure cookers.

    State of the art 25

    Currently, pressure cookers used to cook food are known and comprise a container and a lid provided with coupling means, bayonet type, for mutual engagement in a closed position of the pot, and two handles that are superimposed. in said closing position 30.
    It is also known that these pressure cookers have a steam selector that can be arranged in different positions to regulate different degrees of
    steam output and consequently different cooking pressures.

    As is known, one of the risks of using these pressure cookers is the opening of the lid when there is a residual vapor pressure inside, sufficient to cause burns at the time of opening the lid. 5

    This risk occurs when the user cannot verify or does not ensure that there is no pressure steam inside the pot before proceeding to open it.
     10
    Although different types of pressure cookers are known in the state of the art, the applicant is unaware of the existence of antecedents that present technical, structural and constitutive characteristics similar to those presented by the pressure cooker of the present invention and that have suitable means: on the one hand, so that the user can know by means of a simple visual observation, and without the need for any manipulation if there is pressure inside the pot and, on the other hand, to prevent the user from opening the pot when there is pressure inside it.

    Description of the invention

    The pressure cooker object of the invention is of the type comprising: a container and a lid provided with coupling means for mutual engagement in a closed position of the pot, and of two handles which are arranged superimposed in said position of closing. This pressure cooker has about 25 characteristics aimed at satisfactorily solving the problem described above and in particular to prevent the lid from opening when there is pressure inside the pot.

    For this, the cover includes: 30

     - a locking mechanism of the lid in a closed position, comprising a pin movable between: - a locking position in which
    said pin is housed in a defined recess in the handle of the container, preventing the lid from rotating in a direction of opening of the pot and - an unlocking position in which said pin is released from the recess of the handle allowing the rotation of the lid in said opening direction,
     5
     - an adjustable steam outlet valve,

     - a manual selector for the arrangement of the adjustable valve in different steam outlet positions and the arrangement of the lid locking mechanism in a lid opening position; and 10

     - a pressure indicator movable between positions indicating the existence and absence of pressure inside the pot, said pressure indicator having a suitable configuration to prevent the movement of the locking mechanism pin and the manual selector 15 towards the unlocking position of the locking mechanism when said pressure gauge is in the position indicating the existence of pressure inside the pot.

     With these characteristics it is achieved that the manual selector cannot be arranged in an opening position of the lid and therefore that the locking mechanism of the lid cannot be moved towards an unlocking position while there is pressure inside the lid. cooking pot.

    The pressure gauge is arranged in a visible position, so once the pressure cooker is used, the user must observe the position of the pressure gauge and wait for the pressure gauge to be placed in the indicator position of no pressure inside the pot to proceed to operate the manual selector to the unlocked position of the lid locking mechanism and to rotate the lid in the opening direction. 30

    These and other features of the invention set forth in the claims will be more readily understood in view of the exemplary embodiment shown.
    in the figures described below.

    Preferred Embodiment of the Invention

    The pressure cooker object of the invention is of the type comprising: a container (1) and a lid (2) provided with conventional coupling means (10, 20) 15, bayonet type, referenced in Figure 2, for its mutual engagement in a closed position of the pot, shown in figure 1; and of two handles (11, 21) that in said closing position are superimposed. The opening and closing of the cover (2) is achieved by arranging the coupling means in alternate positions and turning the cover laterally in one or the other direction.

    The cover (2) comprises: - a locking mechanism (22) of said cover (2) in a closed position; - an adjustable steam outlet valve (23), - a manual selector (24) for the arrangement of the adjustable valve (23) in different 25 steam outlet positions and the arrangement of the locking mechanism (22) in one position lid opening; and - a pressure indicator (25) that can be moved between positions indicating the existence and absence of pressure inside the pot.
     30
    The lid also has a safety valve (26) for mandatory use in this type of pressure cooker for safety reasons.

    The locking mechanism (22) of the cover (2) comprises a pin (221) mounted inside the handle (21) of the cover as seen in Figures 5, 6, 7 and 10; It is possible to move between: - a blocking position shown in Figures 4 to 7, in which a first end (222) of said pin (211) is housed in a recess (12) of the handle (11) of the container, 5 preventing the rotation of the lid (2) in a direction of opening the pot and - an unlocking position shown in figures 8 to 10 in which said pin is released from the recess (12) of the handle (11) allowing rotation of the cover (2) in said opening direction.
     10
    The movement of the pin (221) between the locking and unlocking positions is determined by the action of the manual selector (24) on a second end (223) of said pin.

    As can be seen in figures 3 and 8, the manual selector (24) is mounted 15 in the center of the cover (2), coaxially with the adjustable pressure outlet valve (23), and with the possibility of turning between:

    - a first unlocking position (a) of the lid closure (2), shown in figures 8 and 10, in which it keeps the pin (221) in an unlocked position, in which said pin allows the rotation from the lid (2) towards an opening position of the pot;

    - second positions (b, c, d) for regulating the steam outlet, shown respectively in figures 5, 6, and 7, in which it acts on the adjustable valve (3) to vary the steam output of the inside of the pot; and acts on the second end (223) of the pin (221) keeping it in the locked position of Figure 3, in which said pin prevents the lid from rotating towards the pot opening position.
     30
    The manual selector (24) has in its outline a cam profile (241) that acts on the second end (223) of the pin (22) and that disposes it in the unlocked position when said manual selector is in a first
    unlocking position (a) of the lid closure and having it in the locked position when said manual selector (24) is in any of the second positions (b, c, d) for regulating the steam outlet.

    The pressure gauge (25) has a suitable configuration to prevent the movement of the pin (221) of the locking mechanism (22) to the unlocked position, by the manual selector (24), when said pressure gauge (25 ) is in the position indicating the existence of pressure inside the pot.
     10
    In an example shown in Figures 4 and 9, said pressure gauge (25) has a rear portion (251) that protrudes from the inside face of the lid (2) and is exposed to the vapor pressure existing inside pot; and an anterior portion comprising: a proximal section (252) of greater thickness located within the handle (21) of the lid; and a distal section (253) of smaller thickness, which is kept inside the handle (21) when there is no pressure inside the pot and protrudes from the handle (21) when there is pressure inside the pot , which allows visually appreciate the existence or the absence of pressure inside the pot.
      twenty
    As can be seen in figures 4, when there is pressure inside the pot, the pressure gauge (25) moves outwards from the lid, protruding from the handle (21), and the proximal section (252) of greater thickness is placed in the path of the pin (221) keeping it in an operative position of locking the cover; and preventing the manual selector (24) from being able to move 25 towards the unlocking position (a) of the lid closure.

    As can be seen in Figure 9, when there is no pressure inside the pot, the pressure gauge (25) returns to a resting position, and the proximal section (252) of greater thickness is removed from the trajectory of the pin (221) 30 allowing its movement towards a lid unlock position, shown in figure 8, by turning the manual selector (24) towards the lid lock release position (a).

    With these characteristics it is possible that the lid (2) of the pot cannot be opened while there is pressure inside the pot.

    Once the nature of the invention has been sufficiently described, as well as a preferred embodiment, it is stated for the appropriate purposes that the materials, shape, size and arrangement of the described elements may be modified, provided that this does not imply alteration of the essential features of the invention that are claimed below.
