TECHNICAL FIELD

[0001] The utility model relates to a kitchen utensil, in particular to a cooking cover. BACKGROUND

[0002] When cooking with a utensil, a suitable cover is needed to cover the opening of the utensil. When purchasing a utensil product, a cover is usually provided as an accessory.

[0003] The most common material of a cover is glass, and a cover can only fit one size of utensil. If there are multiple sizes of utensils in a household, the corresponding cover needs to be found from the cover rack every time, which is not very convenient. SUMMARY

[0004] The utility model provides a cooking cover which can fit multiple sizes of open cooking utensils.

[0005] To solve the above technical problem, the utility model provides a cooking cover which is used for covering an open cooking utensil. The side of the cooking cover which is in contact with the cooking utensil is the lower side of the cooking cover. The cooking cover is made of food-grade silicone. The cooking cover comprises a centrally formed central part, a handle part and a ring-shaped part. The ring-shaped part surrounds the central part and has an inverted stepped structure. The stepped structure comprises at least two ring surfaces which increase in size in sequence. The ring surfaces comprise a downward horizontal ring surface and an outward vertical ring surface. The ring surface with a larger size is located above the ring surface with a smaller size. Different ring surfaces correspond to different sizes of cooking utensils. The ring-shaped part has a deformation capacity. The horizontal ring surface and / or the vertical ring surface is in contact with the opening rim of the cooking utensil to achieve the sealing of the opening rim of the cooking utensil by the cooking cover. The handle part is located on the upper side of the central part. The central part is further provided with a vent hole.

[0017] Referring to Figure 1 ​​​​The cooking cover 100-1 includes a one-piece central portion 1, a cover handle portion 2 and a ring-shaped portion 3, and is made of food-grade silicone, with a temperature range of -50℃ to 230℃, and can be used as a pot cover when steaming, boiling or braising food, and is also suitable for use in an oven or microwave oven. The central portion 1 is in a sheet structure, and the ring-shaped portion 3 surrounds the central portion 1 and has an inverted stepped structure. The ring-shaped portion 3 and the central portion 1 form an inner recessed cavity, and the cross section of the inner recessed cavity in the up-down direction is in the shape of an isosceles trapezoid. The upper side of the central portion 1 forms a cover handle portion 2, and the cover handle portion 2 is located in the inner recessed cavity. If necessary, those skilled in the art can design the cooking cover into other structures, for example, the cover handle portion can also be assembled to the central portion, which is convenient for transportation, and the connection between the cover handle portion and the central portion can be achieved by using a high-temperature-resistant food-grade plastic connecting piece, i.e., the upper and lower parts of the plastic connecting piece are respectively clamped to the cover handle portion and the central portion.

[0018] Referring to Figure 2 , the lower side of the ring-shaped portion 3 is in the shape of an inverted stepped structure, and includes six annular faces that gradually increase in radial size from bottom to top. One annular face includes a downward transverse annular face and an outward longitudinal annular face, and the six transverse annular faces 3A, 3B, 3C, 3D, 3E and 3F are alternately arranged with the six longitudinal annular faces 3a, 3b, 3c, 3d, 3e and 3f. Different annular faces correspond to different diameters of cooking utensils, and the six annular faces correspond to 18cm, 20cm, 22cm, 24cm, 26cm and 28cm diameter circular cooking utensils, respectively. These six diameters of cooking utensils are most commonly used in daily cooking, and therefore the cooking cover has good practicality. If other special needs of use scenarios are to be met, those skilled in the art can adjust the number and size of the annular faces to adapt to other combinations of diameters of cooking utensils.

[0019] To improve the sealing ability of the cooking cover to the cooking utensil at the container rim, referring to Figure 3 , the transverse annular faces 3A to 3F have a downward slope from inside to outside, and the longitudinal annular faces 3a to 3f have an outward slope from bottom to top. Since the ring-shaped portion 3 has a deformation ability, the inclination angles α of the transverse annular faces and the inclination angles β of the longitudinal annular faces can both change when the cooking cover is placed on the cooking utensil, so as to better fit the open rim of the cooking utensil. Preferably, in the initial state, the inclination angle α of the transverse annular face is 8°±2°, and the inclination angle β of the longitudinal annular face is 9°±2°.

[0020] The position where the rim of the cooking vessel contacts the cooking cover can be different for different shapes and sizes of the cooking vessel, and the rim of the cooking vessel can only contact the longitudinal annular surface or the surface, or only contact the transverse annular surface or the surface, or contact both the transverse annular surface and the longitudinal annular surface. Figure 4 The cooking vessel 200-1 shown has a diameter of about 18 cm, and the side wall is inclined, so that the longitudinal annular surface 3a of the cooking cover 100-1 can only be in contact with the inner wall of the cooking vessel 200-1, or Figure 5 The longitudinal annular surface 3a and the transverse annular surface 3A of the cooking cover 100-1 are in contact with the inner wall and the upper end surface of the cooking vessel 200-1, respectively; Figure 6 The cooking vessel 200-2 shown has a diameter of about 28 cm, and the side wall is vertical, so that the transverse annular surface 3F of the cooking cover 100-1 can only be in contact with the upper end surface of the cooking vessel 200-2. The longitudinal annular surfaces 3a to 3f have an outwardly inclined slope from bottom to top, which has the advantage of better sealing the rim of the inner wall of the cooking vessel, and also has the advantage that each longitudinal annular surface 3a to 3f has a certain guiding effect during the process of covering the cooking cover on the cooking vessel, because each longitudinal annular surface is smaller at the bottom and larger at the top, facilitating insertion into the open end of the cooking vessel.

[0021] The central portion 1 is provided with a vent hole 11, and the vent hole 11 is used to balance the air pressure inside and outside the cooking vessel when the cooking cover is covered on the cooking vessel, so it is not suitable to provide the vent hole 11 on the annular portion 3. When designing the vent hole 11, the diameter of the vent hole 11 should be in a relatively appropriate range, about 3 to 4 mm, so that the vent hole 11 is not easily blocked due to too small diameter, and the exhaust capacity is not too large due to too large diameter, which affects the cooking effect. The number of vent holes 11 is generally one, but if there is a special need, more vent holes 11 can be provided.

[0022] In order to reduce the weight of the cooking cover, the thickness of the cooking cover is relatively thin as a whole, and a plurality of reinforcing ribs 4 are arranged on the upper side of the cooking cover, which can improve the structural stability of the cooking cover and prevent the cooking cover from being too soft. Referring to Figure 1 The cooking cover has eight reinforcing ribs 4, and the reinforcing ribs 4 extend from the handle portion 2 to the edge of the cooking cover in the radial direction of the cooking cover, and the eight reinforcing ribs 4 are arranged at equal angles in the circumferential direction of the cooking cover. In other embodiments of the present application, a material with higher hardness or an increased thickness of the cooking cover can also be used to prevent the cooking cover from being too soft and difficult to use.

[0023] Eight reinforcing ribs 4 divide the upper surface of the central portion 1 into eight regions, four of which are provided with reinforcing blocks 12, each of the four regions being provided with one large and one small reinforcing block 12, and the four pairs of reinforcing blocks 12 are arranged at equal angles along the circumference of the cooking cover, thereby improving the structural stability of the central portion 1. If reinforcing blocks 12 are provided in all eight regions, the bendability of the central portion 1 can be reduced.

[0024] To reduce the surface temperature of the handle portion 2 and prevent the user from being scalded when holding the handle portion 2 to take the cooking cover, the handle portion 2 is hollow. To facilitate the formation of the handle portion 2 in the central portion 1, the lower end of the handle portion 2 is open, and the central portion 1 is also designed with a corresponding hole at the position corresponding to the handle portion 2. To prevent the handle portion 2 from being easily collapsed when being held by the hand, the side wall 22 of the handle portion 2 gradually thickens from bottom to top, and to make the handle portion 2 easy to hold by the hand, the outer diameter of the handle portion 2 gradually increases from bottom to top. Embodiment Two

[0025] Referring to Figure 7 The main difference between the present embodiment and embodiment one is that the cooking cover 100-1 provided by embodiment one is a circular cover, which is suitable for a cooking vessel with a circular opening, while the cooking cover 100-2 provided by the present embodiment is a rectangular cover, which is suitable for a cooking vessel with a rectangular opening, and the handle portion 2-1 of the cooking cover 100-2 disclosed in the present embodiment has a square structure in the horizontal direction, of course, the handle portion 2-1 can also be made into other shapes as needed, such as the circular handle of embodiment one.

[0026] It needs to be emphasized again that the main inventive concept of the present utility model is to use food-grade and high-temperature-resistant silica gel material to make a ring-shaped portion with an inverted stepped structure, and to adapt to open cooking vessels of the same shape but different sizes through the different annular surfaces on the lower side of the ring-shaped portion. As for the shape of the ring-shaped portion, it can be adjusted adaptively according to the shape of the cooking vessel, such as circular, rectangular, oval or other shapes. The above embodiments and drawings are not limited to the product form and style of the present utility model, and any appropriate changes and modifications made by ordinary skilled persons in the art shall be considered as falling within the scope of the present utility model.
