Description

Lid for cooking container

Background

The present invention relates to kitchen articles, in particular to a cooking vessel, such as: pots, casseroles, pans and the like; more particularly, the present invention relates to a lid for a cooking receptacle.

One constant problem in kitchen management, especially in the home interior kitchen, is the management of the lid of the cooking vessel. These lids generally cannot be stored with their respective containers unless at the expense of significant waste of space.

Currently, there are two main solutions to this problem: the first is to consider using a lid large enough to have its convex wall facing the opening of the cooking vessel with which it is used. The convex wall may be continuous or stepped, corresponding to containers of different diameters in common use. One practical problem associated with the use of such "universal" caps is that the smaller the container below, the less stable the cap above. Another practical problem associated with this is that the lid is typically of a relatively large size and is in close proximity, if not touching, to another container on the burner adjacent to the container in which it is used.

Another approach is to create a cap of reduced size to which one or more additional ring elements can be attached to increase its diameter. Although from the user's point of view this solution has a small lid and a larger coverage in line with the requirements, it is much more luminous than the first method. However, it is problematic from the viewpoint of spatial organization. Indeed, if it is said that the annular elements occupy less space than the other lid, they must be stored in order; and they are anyway stable if the connection system between the innermost lid and the outer annular element is rather complex, and they can therefore be very delicate or too expensive.

Furthermore, document US1524185A describes a cover having a fixed central portion to which are attached a plurality of peripheral portions that can slide relative to the central portion, so that the size of the cover can be varied. However, this solution presents problems in positioning the peripheral portion effectively and orderly, and the connection system between the fixed portion and the east China portion is easily contaminated, thus affecting the operation of the cover.

Disclosure of Invention

It is therefore an object of the present invention to provide a cap which can be adapted for use with containers of various diameters, which is relatively simple in construction and which is ergonomic from a point of view of use, as well as from a point of view of the space occupied when not in use.

Accordingly, the object of the present invention is a lid for a cooking receptacle, comprising: a closed surface consisting of a plurality of substantially sector-shaped plates, and substantially identical to each other, each of said plates being provided with a linear slot disposed along the bisector of the respective sector, said slot extending substantially from the vertex to the arch, said slots of all said plates being crossed by a single pin slidably movable in said slot, and said plates being joined together in succession along respective sides and overlapping in a spiral succession in a free-swinging manner; the pin may be connected to a handle means of the lid. Two shields are provided above and below the closed plane, mechanically connected to the pin, to provide a firm support to the structure of the lid and to protect its mechanism, as appropriate.

In a preferred embodiment, the plates making up the closure surface are at least four, and preferably at least seven. The number of plates is a compromise between the stiffness of the individual plates, the thickness of the set of plates at the centre of the lid after stacking on each other and the performance of the mechanism of the lid itself.

In another preferred embodiment, the last plate (i.e. the one located at the upper end of the spiral arrangement) and at least one intermediate plate are provided with gripping means protruding radially outwards, and are preferably constituted by a part of the plate.

In another variant, the plate is provided with a plurality of through holes, the lid thus being configured as a splash guard, while still retaining the same dimensional variability.

Detailed Description

Fig. 1 is a plan view of the lid of the present invention in a fully open position. 1 denotes a closed plane comprising a plurality of (seven in the present embodiment) plates shaped like sectors, which are substantially identical to each other; the plate 101 (also shown in fig. 6A) has a through hole 111, the through hole 111 being located on the side of the sector of the plate near the arc; these through holes allow two consecutive plates to be connected by a rivet 121. Similarly, the plate 201 has holes 211 on the sides of the sectors near the circular arc, the plate 201 being connected to the respective holes 111 of the plate 101 by rivets 221, the plate 201 also having wings 231 projecting radially outwards, through holes 241 being provided on the wings 231. A shield 2 is arranged on the plate in the best way described below, with a handle grip 3 projecting axially from the middle. In fig. 2, the lid of the present invention is shown in a fully closed configuration; like parts correspond to like reference numerals.

FIG. 3 is a longitudinal cross-sectional view of the lid shown in FIG. 1; like parts correspond to like reference numerals. It can be seen that the closed plane formed by the

plates

101 and 201 is enclosed between the two

shrouds

2 and 102, the pin 103 passing through the

shrouds

2, 102 and the

plates

101, 201 and then being connected to the threaded cavity of the handle 3 by its own threaded end 123. The pin 103 is further provided with a groove 113 for positioning a sigma-type locking ring or the like. Also from fig. 3, the helical overlap between the different plates can be noted. The cross-section in fig. 4 shows a similar situation for the lid shown in fig. 2 in the closed configuration.

Fig. 5 shows a cross-sectional view of the device shown in fig. 3, with the upper shield 2 and the handle 3 removed; like parts correspond to like reference numerals. It is evident from the figures that all the

plates

101, 201 are provided with a

slot

131, 251 along the bisector of the angle of each sector, which extends from the vertex of the sector itself by about half the radius. The slot cooperates with a pin 103, which pin 103 can slide from one end to the other.

FIG. 6A shows a plate 101 of the aforementioned cover; the plate has holes 111, which holes 111 are located on the sides of the sector close to the arc of a circle, the slot 131 following the bisector of an angle, the vertex of which is suitably rounded. Fig. 6B shows a plate 201, which has substantially the same features as the plate 101, but the plate 201 is provided with a wing 231, and a through hole 241 is provided in the wing 231, and the wing 231 protrudes radially outward with respect to the sector, as shown in the figure by a dotted line for distinction.

Figure 7 shows a variant of the invention in which a single plate 301 is provided with not only holes 311 and slots 331 but also a plurality of small holes 341 to make the closure plane of the lid a splatter shield instead of a real lid.

The operation and construction of the lid of the present invention will be seen from the following. As mentioned in the background of the invention above, in order to propose an effective solution to the problems evident in the prior art, it is necessary to devise a device that allows to significantly vary the diameter of the closing surface without the need to add or remove elements; the lid-operated mechanism proposed according to the invention operates effectively in this sense. The seven

plates

101, 201 forming the cover as shown in figures 1-5, are provided with

respective slots

131, 251 through which the pins 103 pass, are mutually superposed anticlockwise and are rotatable about the

rivets

121, 221 provided in the

respective holes

111, 211.

When the lid is in the fully open configuration as shown in fig. 5, if the projecting wings 231 of the two plates 201 are grasped and the two plates 201 are pushed against each other, as a result of which the

slots

131, 251 of the

plates

101, 201 slide on the pins and then the outer diameter of the closing plane 1 decreases until it becomes the fully closed configuration as shown in fig. 2 and 4. Conversely, to increase the diameter of the closing plane 1, it is necessary to move the two plates 201 away from each other, in which case the pin will move in the slot until it returns to a position near the respective vertex, as shown in fig. 5.

Can be made of several plates, whereby a certain number represents an effective compromise between the best performance of the device and its constructive simplicity; if the number of plates is a small number, it should have a higher rigidity to ensure the stability of the lid, and must have a greater thickness accordingly; on the other hand, if the number of plates is a large number, they must be thin enough so that their overlap is not too cumbersome. In various methods, a number of plates between four and nine is preferred. The plate provided with protruding wings equipped with gripping means, i.e. wings 231 and holes 241 of plate 201, is located at the upper end of the spiral overlap and in a middle position, preferably diametrically opposite to the plate provided at the upper end. The plates forming the closure surfaces may be made of a metallic material, such as aluminium, steel and their respective alloys, or of a plastic material.

The

shields

2, 102 are located above and below the closure surface in order to provide guidance as the diameter changes while supporting the closure surface itself in use, and also to provide sufficient protection for the mechanism formed by the combination of the slots and pins on the plate, which can hinder or limit its ability to operate, from vapors and splashes emerging from the cooking vessel in which the lid is used. The diameter of the shield is preferably substantially equal to half the diameter of the closure surface of the lid.

The plate in a variant of the invention shown in fig. 7, which has a plurality of small holes 341, allows to create a splash guard with the same functional characteristics as the cap of the invention with variable diameter.

The lid according to the present invention solves the outstanding problems of the prior art in a very effective manner, providing a single device which can be adapted to a plurality of cooking vessels and which, in the closed configuration, occupies little space. It should be noted that the gripping means of the plate provided with radially projecting wings can be used to facilitate the hanging of the lid on the hook, increasing the practicality of its use.
