Abstract

The lid (1) is closed by placing it on top of the saucepan (2) and then twisting it to a small degree in a counter-clockwise direction.

Description


  



   This invention relates to a pressure cooker for left-handers. Pressure cookers are pans with a sealable lid, the lid of which is equipped with a pressure relief valve in the center. Under the high pressure in the pressure cooker, higher steam temperatures can be achieved, which reduces the cooking time accordingly. To seal such a pressure cooker tightly, it has an outwardly projecting edge with regularly arranged recesses. The associated cover, on the other hand, has a circumferential edge running perpendicular to the cover plane, with some edge sections being cantilevered inwards and thus forming cantilevered edge sections. A rubber seal inserted there runs along the peripheral edge of the cover and is held by the projecting edge portions of the cover.

   To put it on, the lid with its radially protruding handle is gripped by a right-hander with the right hand and, viewed from above, rotated counter-clockwise with respect to the pan handle by about 30 ° relative to the pan handle, which is also protruding with the left hand put on the pan. In this position of the lid in relation to the pan, the non-folded edge sections of the lid lie over the outwardly projecting edge sections on the pan, and the recesses on the pan edge lie opposite the inwardly projecting edge sections on the cover. For this reason, the lid with its edge falls over the edge of the pan, so to speak.

   Now the lid is turned clockwise in relation to the pan with the right hand until the lid handle, which the user holds with the left hand, stops just above the pan handle. The cantilevered edge sections of the lid and pan slide over each other during this rotary movement and claw. They are shaped in such a way that they form a rising sliding surface at both ends, so that during this rotary movement the lid is first pulled towards the pan and the rubber seal is pressed tightly onto the pan edge. The lid is then turned further in the manner of a bayonet catch. The inside of the circumferential edge of the cover, which is perpendicular to the cover plane, has an inwardly directed cam at at least two points on the front end of the circumferential edge section in the closing direction of rotation.

   The lid can be turned on the pan until these cams are in contact with the next projection on the pan edge. If the cams are on, the handles of the pan and lid point in the same direction. If the lid is closed in this way, the steam cooking process can be started. To release the lid after cooking is complete, the pressure cooker must first cool down with its contents, after which the lid can be relieved and then removed. A right-handed person again holds the pan handle with the left hand and turns the lid with the right hand counterclockwise by approx. 30 ° until the cantilevered edge sections of the lid lie opposite the recesses on the cantilevered edge of the pan, in which position the Lid can be lifted away from the edge of the pan.

   A spring-loaded pin is inserted in the lid handle, directed towards the center of the lid, which pushes the rubber seal at this point from the outside against the middle of the lid. When the lid is closed, this pin is pressed into the lid handle and the rubber seal is also tight at this point. When opened, however, the seal first of all leaks there, due to the deformation of the rubber seal due to this spring-loaded pin, and the pressure cooker is therefore relieved somewhat of the pressure. In a later phase of the loosening rotary movement, the steam flows around the rubber seal and the steam can also escape through holes in the peripheral edge of the lid, so that the pressure in the saucepan is completely relieved of pressure before the lid can be removed.



   For left-handed people, the handling of such a pressure cooker proves to be completely against the hand. The left-hander notoriously grips the pan handle with his right hand and the lid handle with his left hand. Logically, he is then tempted to close the lid counterclockwise. In conventional pressure cookers, the left-handed person must twist the lid handle from above, turning it about 30 ° counter-clockwise in relation to the pan and its handle, for which purpose they have to cross their right arm with their left arm. This movement as well as the subsequent closing of the lid clockwise runs massively against the left hand person. Even worse is opening the lid after cooking is complete.

   For this purpose, the left-handed person automatically grips the pan handle with the right hand and the lid handle with the left hand. Then she tries to loosen the lid by turning the lid handle clockwise. But that's exactly the wrong direction of rotation. If the person does not succeed, that is, if the lid cannot be swiveled immediately in this direction, they often assume that it is jammed. Either she notices it and then swings the lid against her hand in the right direction, or she tries to overcome the supposed jam with force.

   To do this, she turns the lid clockwise by force until the stop cams on the edge of the lid expand by stretching the peripheral edge onto the cantilevered edge sections on the pan and the lid finally clings to the pan so that it can no longer be opened in the correct direction of rotation , In such an extreme case, which is not uncommon for left-handed people, the pan must be opened by a specialist. Steam cookers with such deformed lid edges and hooked lids are repeatedly sent to the manufacturers for repair.



   It is therefore the object of the present invention to provide a pressure cooker for left-handers, which remedies this problem and makes handling for left-handers significantly easier.



   This object is achieved by a pressure cooker for left-handers, consisting of a pan and an associated lid, each with a radially protruding handle and a rubber seal held in the lid, the pan edge having an outwardly projecting edge with recesses and projecting edge sections and the Lid has a circumferential edge perpendicular to the lid plane with inwardly projecting edge sections, the projecting edge sections on the lid of the lid being in the opposite position to the recesses on the pan edge, and which is characterized in that the lid can be closed in a counterclockwise direction by a limited twisting on the pan.



   In the figures, such a pressure cooker is shown, and its construction, handling and operation is explained below.



   It shows: Fig. 1: A view of the pan obliquely from above and the associated lid in an inverted position; Fig. 2: The pan with the lid in the fitting position, before the closing movement; Fig. 3: The pan lid with the indicated closing and release direction.



   In Fig. 1 a pan 2 is shown with the associated lid 1, the lid is drawn here in the upside-down position so that its underside 3 can be viewed. It can be seen that the pan 2 has an outwardly projecting edge 4 which has a number of recesses 5 and projecting edge sections 6. It also has a radially looking handle 7. The associated cover 1 is shown here in an inverted position, so that the view of its underside 3 is clear. The lid peripheral edge 8 runs perpendicular to the lid plane. A plurality of inwardly projecting edge sections 9 are formed on the edge 8 by bending them at 90 °. A pressure relief valve 10 is installed in the center of the cover.

   A pin 12 is mounted in the lid handle 11, which is spring-loaded and can be pushed into the lid handle 11 in the radial direction of the lid. A rubber seal 13 is inserted along the peripheral edge 8 of the cover 1 and is held in place by the projecting edge sections 9. The pin 12 presses with its end face onto the outside of this rubber seal 13 and at this point pushes it slightly towards the center of the lid 1, in order to relieve the pressure on the saucepan at the beginning of the opening process. The two holes 15 positioned behind the rubber seal 13 in the peripheral edge 8 of the cover 1 also serve this purpose, of which only the one facing the viewer is visible here.

   On the inside of the peripheral edge 8 of the lid 1 there are now two cams 14 which limit the closing rotation since they find a stop on the cantilevered edge sections 6 of the pan 2. The cantilevered edge sections 9; 6 of the lid 1 and pan 2 and these cams 14 are now arranged in such a way that the lid 1 placed on the pan 2 can be closed by a counterclockwise rotation and opened again by a clockwise rotation.



   Fig. 2 shows the pan 2 with the lid 1 for left-handers, the lid 2 being in the position shown here after it has been placed on the pan 2 from above. The lid handle 11 is pivoted away from the latter in a clockwise direction with respect to the pan handle 7 by about 30 °. To close the lid, the pan handle 7 is gripped by the left-hander with the right hand and the lid handle 11 is turned with the left hand in the counterclockwise direction in the direction of the arrow shown until the lid and pan handles are one above the other. The lid 1 is loosened in exactly the opposite direction, ie clockwise.



   3 shows a pan lid 1, as it is advantageously marked. Because it differs from the usual pan lids and saucepans in the wrong closing direction, it is important that the closing direction is clearly marked. This is ensured by means of labeled arrows, so that everyone immediately knows how to use the saucepan. digits directory
