Apparatus for cooking, serving and storing food or the like
The invention relates to a device for cooking, serving and storing food and the like, which device, seen in the state of use, is provided with a tray with a bottom wall and upright side wall defining an internal space of the dish, and a circumferential on the top of the side wall the ridge ridge, and furthermore is provided with a lid with a top wall and a hanging side wall, which side wall at the bottom is provided with a circumferentially running lip with a bottom surface running complementary to the top surface of the ridge ridge, wherein the The lid is rotatable relative to the tray between a closed position in which the bottom surface of the lip of the lid engages the top surface of the ridge ridge thereof substantially over the entire circumference of the tray, and a ventilation position in which the lid is relative to the of the saucer and the bottom surface of the lip is only partially on top surface engages the ridge ledge.
Such a device is known from US patent 4,917,262. With the aid of this known device, the food can be covered inside the dish while it is being cooked. Covered cooking aids in retaining heat and moisture in the dish and may otherwise aid in the cooking process. Even if covered cooking is not desired, the lid can be used to assist in keeping the contents of the dish warm. The term "dish" is used in a general sense to indicate refractory dishes, such as a roasting dish, which is suitable for use in a microwave or conventional oven. The term "dish" also includes a 20 cooking utensil intended for use on a cooking element on a stove.
For some applications it is advantageous to be able to cook in a ventilated or unventilated state. Some recipes require a combination of the two. In microwave cooking, in particular, it is often often necessary to cook for relatively short periods of time and then either remove the dish from the microwave to stir the contents or twist the dish in the oven and at different power levels to cook. In addition, it may be required to cook with the dish in a ventilated state for a certain time and then with the dish in a non-ventilated state for a certain time. In such situations it is necessary to safely ventilate the steam or vapor that may have collected in the interior of the dish during a cooking cycle.
For this purpose, in the known device according to US patent 4,917,262, the top surface of the ridge ridge and the bottom surface of the lip are made complementary, and each have at least one step-shaped portion. In the closed, unventilated position, these stepped sections fully engage one another and can be moved apart by rotating the lid relative to the tray, so that ventilation openings are formed between the stepped sections, through which steam can escape radially. A drawback of this known device is that the steam exits radially in two directions, namely where the openings caused by the rotation are created between the stepped parts. One of these openings may face the user, so that there is a risk of these burns.
The object of the invention is to provide a device of the said type, wherein this drawback is eliminated in a simple, yet effective manner.
To this end, the device according to the invention is characterized in that the top surface of the ridge ridge and correspondingly the bottom surface of the lip have two opposite first lower parts and between these higher parts two second parts, the substantially horizontal and parallel running first and second parts are in each case connected by inclined parts 45, the inclined parts of the lip connecting via curved parts to the adjacent first lower parts of the lip, so that a ventilated intermediate position can be reached when the lid is rotated from the closed position in which between the bottom surface of the lip and the top surface of the cam ridge in the region of the inclined portions of the top surface of the cam ridge and the curved portions of the inclined portions of the bottom surface of the lip, only a point-50 contact prevails at two diametrically opposite places d ie determine a pivot around which the lid can be pivoted. With the device according to the invention, the user has the option, by simple handling, to select not only the degree of ventilation, but also the direction of the steam flowing out. After all, during rotation of the cover between the non-ventilated position and the fully ventilated position, it is possible to direct the outflowing steam from the user by means of a pivot of the cover around the pivot axis formed. In addition, the device according to the invention advantageously differs from the prior art in that the rotation of the lid and the tray relative to each other can take place in both directions, ie the lid 1935S5 2 can be rotated in one or can be opened in the other direction, thereby always achieving the favorable intermediate position in which the lid can be pivoted.
In a preferred embodiment of the device according to the invention, wherein the tray is provided with two diametrically opposite radially outwardly projecting handles, the lid is provided with two diametrically opposite radially outwardly projecting handles, each saucer handle extends substantially in radial orientation with respect to a first lower portion of the top surface of the ridge ridge, each cover handle extending substantially in radial orientation with respect to a first lower portion of the lower surface of the lip, and with a cover handle and a corresponding saucer handle is vertically superimposed in the closed position and staggered relative to each other in the ventilation position.
The advantage of this embodiment is that it allows the pivoting of the lid to be easily accomplished by manually moving the handle of the lid towards the associated handle of the dish, thereby also ensuring that the steam escapes in a direction which 15 is turned away from the hand.
The invention will be explained in more detail below with reference to the drawing, which shows an embodiment of the dish according to the invention.
Figure 1 shows a perspective view of the tray, with the lid displaced relative thereto, the bottom of which is visible; Figure 2 shows a side view of the lid above the tray, with part of the tray flange removed; Figure 3 shows a side view of the lid above the tray offset from Figure 2, with part of the tray flange removed; Figure 4 shows a top view of the lid in an unventilated state on the tray; Figure 5 shows a bottom view of the dish; figure 6 shows a cross-section along the line Vl-VI in figure 4; figure 7 shows a cross-section along the line VII-VII in figure 4; Figure 8 shows a cross section according to Figure 6, however, the lid is rotated 90 ° relative to the tray and the tray is in a ventilated condition, and Figure 9 shows a cross section according to Figure 7, however the lid is rotated 90 ° relative to the tray. dish is rotated and the dish is in a ventilated condition.
Figures 1, 2 and 3 show a dish 50 and a complementary lid 10. The dish and lid are intended to be used, for example, as a roasting dish or for other cooking purposes. The tray 50 and the lid 10 are made of any suitable material which can withstand both the high temperatures associated with cooking in a microwave or conventional oven and the low temperatures associated with storage in a refrigerator or freezer.
The tray 50, as best seen in Figures 1 through 3 and 6 through 9, has a bottom wall 52 which transitions into an upwardly extending side wall 54. The side wall 54 has a circumferential and outwardly extending rim having a cam ridge 56. An upwardly extending flange 76 surrounds the cam ridge 56. The flange 76 terminates in an upper edge 80 and has an internal surface 78.
The cam ledge 56 includes opposed first lower portions 58 and second upper portions 64 connected by inclined portions 70. Each of the first lower portions 58 45 has an upper and lower surface 60 and 62, respectively, while each second upper portion 64 has an upper and lower surface 66 and 68, respectively. The inclined portions 70 are arranged in diametrically opposed pairs and each have an upper surface 72 and a lower surface 74. As can be seen in Figures 2 and 3, the second upper portions 64 are vertically offset from the first lower portions 58. The top surfaces 60; 66; 72 of the first lower portions 58, the 50 second upper portions 64 and the inclined portions 70 together form a continuous, smooth, raised cam surface. Similarly, the bottom surfaces 62; 68; 74 of the first lower portions 58, the second upper portions 64 and the inclined portions 70 together form a continuous smooth downwardly cam surface. Each inclined surface 72 intersects the adjacent, generally horizontally extending top surface 60 of a first lower portion 58 at an obtuse angle.
55 Opposite handles 82 are positioned adjacent to the first lower portions 58 of the ridge ridge and extend outwardly therefrom. Each handle 82 extends broadly in the same plane as the top surface 60 of the first lower portion 58. As can be seen in Figures 3 193555 2 and 3, the inclined portions 70 of the cam ridge are positioned outward from the ends of the handles . The handles 82 have a substantially flat top surface 84 and a bottom surface 86. The bottom surface 86 of each handle has a recess 88 to facilitate gripping. The bottom wall 52 of the tray has an outer surface 90 with radially extending protrusions 92 mounted thereon. The protrusions 92 serve to arrange the bottom wall 52 spaced above the top of the counter or oven surface and also to cooperate with projections correspondingly formed on the lid 10.
As shown in Figures 1, 2 and 3, the lid 10 has a generally planar top wall 12 which merges into a downwardly extending sidewall 14. At the bottom portion of the sidewall 14 there is an outwardly extending rim 16, while a pair of opposed handles 18 extend outwardly from the rim 16. The handles 18 have a smooth top surface 20 and "finger grippable" recesses 24 formed in the bottom surface 22 of each handle.
A lip 26 extends down below the rim 16. The lip 26 includes opposed first lower portions 28 as well as second upper portions 30 which are connected by diametrically opposed inclined portions 32. The lip 26 terminates in a lip surface 36 which forms a continuously smooth surface which the cam ridge 56 has an appropriate contour. The lip surfaces 36 adjacent to the diametrically opposed lip portions 32 are designated 36a and 36b. The lip surfaces 36a and 36b include curved joints with the surfaces of the adjacent first lower lip portions 28.
The handles 18 extend outwardly from the rim 16 above the opposing first lower portions 28 of the lip 26, each handle 18 extending broadly in one plane with the rim 16. As shown in Figures 1 / m 3, the inclined portions 32 are placed outwardly from the ends of the handles 18.
The top surface 38 of the top wall 12 is provided with radially extending protrusions 40, which can cooperate with the protrusions 92 of the tray 50.
It can now be seen that the lid 10 can be mounted on the tray 50 in a closed or unventilated position (Figures 6 and 7) as well as an open or a ventilated position (Figures 8 and 9). In the unventilated position, it can be seen that the lip 26 engages a cam ridge 56, while the lid edge 16 engages the top edge 80 of the tray flange 76. In particular, the surface 36 of the lip 26 engages the top surfaces 60 of the first lower portions 58, the upper surfaces 66 of the second upper portions 64 and the upper surfaces 72 of the inclined portions 70 to block access to the interior of the tray 50. The underside of the lid edge 16 simultaneously engages the edge 80 of the upwardly facing tray flange 76, creating a labyrinth through which trapped steam or vapor must pass for escape.
As shown in Figures 1, 2 and 6, the saucer handles 82 and lid handles 18 are vertically aligned when the saucer 50 and lid 10 are in the closed or unventilated position. This provides a simple indication to the user that the content is heated or stored in the unventilated state. As shown in Figures 8 and 9, in the vented condition, the lip 26 partially engages the cam ledge 56, while the lid edge 16 is completely out of engagement with the top edge 80 of the tray flange 76. In particular, it can be seen that when the handles 18 of the lid 10 are displaced by 90 ° relative to the handles 82 of the saucer 50, the bottom surfaces 36 of the first lower portions 28 of the lip 26 engage the upper surfaces 66 of the second upper portions 64 of the cam ridge 56 of the tray 50. The drawing further shows that it is possible to orient the lid 10 with respect to the tray 50 in different angular positions on the tray 50 in a ventilated condition. In the ventilated position of the lid 10 on the tray 50, it can be seen that the tray handles 82 and the lid handles 18 are not in one vertical line, providing a convenient visual indication that the lid 10 and the tray 50 are used in the ventilated condition.
The cover 10 can be moved from the ventilated to the unventilated position by rotating the cover 10 on the tray 50 in or counterclockwise. For example, when the lid 10 is rotated counterclockwise, the lip surfaces 36a engage the adjacent inclined cam ridge surfaces 72 at diametrically opposed positions on the cam ridge 56. As the user continues to counterclockwise rotation of the lid 10, the lip surfaces 36a slide upwardly along the opposed oblique surfaces 72, lifting the lip surface 36 out of engagement with the cam ridge surfaces 60 and 66. If the lid 10 is rotated in the
