DETAILED DESCRIPTION OF THE INVENTION 
With reference to FIG. 1 there is shown a cookware vessel 1 of the present invention. The vessel 1 may be of a shape such that it can easily nest with other, like vessels 1. This will enable the efficient storage of a set of vessels 1 which may be particularly important in situations where storage space is at a premium such as in apartments, boats, caravans etc. In the preferred embodiment the vessel 1 is of a generally square plan shape with rounded corners as shown in FIG. 1.
The cookware vessel 1 may be manufactured from any suitable material or combination of materials. Possible combinations of materials are outlined below:

    
    
        stainless steel exterior (magnetized for induction), copper or aluminium inside and a stainless steel interior, or
        stainless steel with an aluminium base (disk) stamped on, or
        annodised aluminium exterior and stainless steel interior.
    
    


It should be appreciated that other combinations of materials may also be used. The cookware vessel 1 may or may not include a coating layer such as Teflon or similar. The cookware vessel 1 may or may not be suitable for induction cooking.
The cookware vessel 1 includes at least one handle attachment location 2 which may be an indent in the rim of the vessel 1. Preferably there are four handle attachment locations 2 which are located centrally of each side of the vessel 1. The handle attachment locations 2 are suitable for removable attachment of the handle 3.
When the vessel 1 is not in use, it may be stored in an efficient manner with other, like vessels 1 by removing the handle 3 from the attachment location and nesting the vessel 1 with the other like vessels 1. The complementary shape of the other, like vessels 1 enables the nesting.
FIG. 2 shows an alternatively shaped vessel 1 which may be used as a frying pan for example. The vessel 1 of FIG. 2 only differs in its shape, it may be manufactured from the same materials and may also include four handle attachment locations 2.
FIGS. 3 to 6 show different views of an exemplary cookware vessel 1 of FIG. 1 without the handle 3 attached to an attachment location 2.
FIGS. 7 to 11 show different views of an exemplary vessel 1 (i.e. a frying pan) of FIG. 2 without the handle 3 attached to an attachment location 2.
The handle 3 is shown in more detail in FIGS. 12 to 15. The handle 3 may include a die cast tongue 4 and knob 5. The tongue 4 and knob 5 are positioned relative to one another in a way to facilitate attachment of the handle 3 to an attachment location 2 of a vessel 1. When the handle 3 is attached to the attachment location 2 it is not able to slide along the rim 6 of the vessel 1, this is due to the attachment location 2 being recessed slightly from the rim 6 that surrounds it.
The tongue 4 may be moveable with respect to the knob 5 to allow for attachment to the attachment location 2. Once positioned on the attachment location, relative movement between the tongue 4 and the knob 5 may allow for locking of the handle to the vessel 1.
With reference to FIG. 16 there is shown a lid 7 suitable for use with a vessel 1. The lid may include a band 8 which may be placed around the edge of the lid 7. The band 8 may be silicone or another similar material and helps create a seal with the vessel 1. Sealing the vessel 1 may be particularly important for creating an air tight environment for storing food inside the vessel 1.
The lid 7 may be stainless steel or other suitable material and may include a vent 9, which allows for the venting of gases from the vessel 1 during cooking (i.e. when the band 8 is not located on the lid 7). The band 8 covers the lid vent 9 when it is located on the lid 7.
The lid 7 may also include a handle 10.
The banded lid can be used to cover the vessel during cooling and refrigeration thereby to ensure a partial vacuum can develop above the vessel contained foodstuff.
An alternative embodiment of the handle of the present invention will now be described with reference to FIGS. 18 to 22B.
FIG. 18 shows complementary and preferably mirror imaged components however able to be held together to define by preferably a region 12 of each a proximal jaw.
Each of the components 11 when held together in the assembled form such as shown by any suitable screws or other means is adapted to guidably locate a slide 13 and a cam lever 14 to be located by its pivot 15 with a pin 16 from regions such as 17 from each of the components 11. Springs 18 are to act on formations 19 of the slide at one end and on the pin 16 at the other end.
The nose region 20 of the lever is a transition point between two substantially stable conditions for the over centred spring action between the lever and the slide 13 such that when in the condition as shown in FIG. 22A there is stability that accords with gripping of a cookware component and there is no tendency for the lever to fall away and such that when in the condition as shown in FIG. 22B (the springs not being shown for ease of depiction) is stable in a condition able to be disengaged from a cookware vessel or to be inserted into such cookware vessel.
FIGS. 23 and 24 show that the vessel 1, even when lidded, can be used in a vented or non-vented manner by a lid assembly.
FIGS. 25 show a lid assembly in accordance with the present invention where a lid assembly 21 has a slide (eg. of plastics material or a metal) actuable under the knob member 22 to encroach over the scalloped away region which is a relief 23 of the lid body proper 24 so as to reduce venting between the region of the handle (in that case departing somewhat from that previously described). As can be seen the knob 22 can be used to move the associated slide 25 from a condition that does not encroach upon the relief 23 to a position as in to the right in FIG. 25 where the whole of the relief 23 has been sealed by part of the slide 25.
In an alternative, preferred embodiment of the handle 3 a single spring 30 may be provided internally of the slidable member 13 to bias the slideably member towards the nose region 20 of the lever 14. FIG. 26A corresponds with a locked condition in which the jaw pair 12 and 13 are closer together. FIG. 26B corresponds with an unlocked condition in which the jaw pair 12 and 13 are further apart.
The lever 14 is articulatable between two stable conditions, corresponding to the locked and unlocked conditions of the jaw pair 12 and 13. A cam profile exists adjacent the nose region 20 of the lever 14 such that as the lever 14 pivots between its two stable conditions the position of the slide 13 is adjusted. The slide 13 on which the cam profile acts can be caused to slide, against the bias of the spring 30, to the locked condition of FIG. 26A, and can be biased to the unlocked condition of 26B when the cam profiled of the nose region moves to position shown in FIG. 26B.
A lever release button 31 may be provided to cause the lever 13 to pivot. Alternatively, the lever may be pushed down at its end region 32 to cause the pivoting.
A sleeve 33 may be provided on the inside of the fixed jaw 12 along with inserts 34 that may be provided on the end of the sliding member 13. The sleeve 33 and inserts 34 will engage with the vessel 1 when a handle is used to grip a vessel 1 and is in the locked condition. The sleeve and inserts may be made of silicon or any other suitable material.
With reference to FIG. 27 an exploded view of the preferred handle assembly is shown. The various parts and preferred materials for those parts are listed below:
3—handle body (nylon).
14—lever (nylon).
20—nose region (stainless steel).
13—sliding member of the jaw pair (stainless steel).
12—fixed jaw (stainless steel).
31—lever release button 31 (stainless steel)
33—fixed jaw sleeve (silicon)
34—sliding member inserts (silicon)
It should be appreciated that the handle 3 may be assembled in a different manner and from different components as shown with reference to FIG. 27. It should also be appreciated that the materials of the components may differ from what is listed above, as would be apparent to a person skilled in the art.
FIG. 28 shows the preferred handle 3 fully assembled.
Persons skilled in the art will appreciate how handle assemblies for example as shown in FIG. 28 can be engaged to the attachment location 2 of cookware vessels.
FIG. 29 shows a cookware vessel 1 with an associated handle 3 and lid assembly 21. It should be appreciated that the handle 3 is suitable for attachment to any of the attachment locations 2 of the cookware vessel and indeed any attachment location 2 of a like cookware vessel irrespective of its size. Once a handle is located on a cookware vessel 1, the associated lid 21 may be placed onto the vessel such that the relief 23 corresponds with the attachment location 2 where the handle is located. The knob 22 can then be used to adjust the slide 25 depending on the amount of venting that is desired.
When no handle is attached to a cookware vessel, the slide 25 of a lid 21 can be adjusted to substantially close the relief 23. Such a lid 21 can then be placed on a corresponding vessel to substantially seal the vessel.
With reference to FIGS. 30 and 31 it is evident that the cookware vessels, lid assembly 21 and handle of the present invention allow for efficient nesting of the various components. The cookware vessels 1 may sequentially nest, in order of their size, for efficient stowage. Even with their associated lid 21 located thereon, the lidded vessels can nest efficiently as shown in FIGS. 30 and 31.
To enable efficient lidded nesting of the cookware vessels, the lids 21 may be provided with handles 34 that define upwardly extending grippable regions 35 and hollow regions 36 located substantially below the grippable regions 35. Preferably the hollow regions 36 of the handles 34 are complementary with the form of the main lid body when a handle is attached thereto. In this respect, the main lid body may have a convex portion centrally of a concave portion. The convex portion being suitable for accepting the hollow region 36 of a handle when such a handle is attached thereto.
When the lidded cookware vessels are sequentially nested, as shown in FIGS. 30 and 31, the grippable region 35 of an inner nested vessel may be at least partially received in the hollow region 36 of a more outwardly nested vessel. This may reduce interference between the lids and therefore allows for efficient nesting of a set of cookware vessels and their associated lids.
The handle 3 may fit within the most inwardly nested vessel as shown in FIG. 31.
It is envisaged that sets of two or more cookware vessels may be provided with correspondingly sized lids and a handle. Such a set has the benefit whereby the handle can be used on any of the vessels of the set, and the lidded vessels may nest for efficient stowage as shown in FIGS. 30 and 31. Such a cookware set lends itself to situations where storage space is at a premium such as in apartments, boats, caravans etc.
Where in the foregoing description reference has been made to elements or integers having known equivalents, then such equivalents are included as if they were individually set forth.
Although the invention has been described by way of example and with reference to particular embodiments, it is to be understood that modifications and/or improvements may be made without departing from the scope or spirit of the invention.

said attachment location being recessed from a surrounding portion of the rim, such that the handle, once engaged with the vessel within the recess of the attachment location, is restricted from moving along the rim of the vessel,
and further comprising at least one lid assembly able to fit on the cookware vessel and to close, or at least substantially close, the cookware vessel,

and wherein said handle, once engaged, at least in part intrudes inwardly of a general envelope of the lid when viewed in plan when the lid is fitted on the vessel,
said lid assembly comprising
a lid body, said lid body defining a vent aperture that extends inwardly from the general envelope of the lid body, wherein an inwardly intruding part of said handle, once the handle is engaged at the attachment location, can be accommodated within the vent aperture when the lid is fitted to the vessel.

2. A cookware assembly or set as claimed in claim 1 wherein the cookware vessel is of a form to enable nesting at least in part with a like vessel of a smaller or larger size, if not also partially nestable with one of the same size.

3. A cookware assembly or set as claimed in claim 1 wherein the cookware vessel is of a form to enable sequential nesting with a like vessel of a smaller or larger size, one within the other in order of their size, even with a corresponding lid located on each nested vessel.

4. A cookware assembly or set as claimed in claim 3 wherein each lid has a handle located substantially centrally of the lid body and has a grippable region extending upwardly substantially beyond the lid body, and a hollow region located below the grippable region, wherein the hollow region is dimensioned so that it can receive at least a portion of the grippable region of another like lid placed beneath so as to prevent interference between the lid handle and another lid when a plurality of cookware vessels are sequentially nested with their lids located thereon.

5. A cookware assembly or set as claimed in claim 1 wherein the jaw pair are shaped such that they are complementary with the attachment location to lock the handle to the vessel in a rigid, weight bearing manner.

6. A cookware assembly or set as claimed in claim 1 wherein the handle comprises or includes:
a pair of jaw elements at a proximal region of the handle,
an actuator to adjust the relative position of the pair of jaw elements,
wherein the relative position of the jaw elements facilitates attachment of the handle to an attachment location provided as a relief in the rim of a cookware vessel such that a first jaw of the jaw pair locates substantially inside the vessel and a second jaw of the jaw pair locates substantially outside of the vessel.

7. A cookware assembly or set as claimed in claim 6 wherein the position of one or both jaws of the jaw pair may be adjusted between a locked condition where the jaws are closer together than a further apart, unlocked condition.

8. A cookware assembly or set as claimed in claim 7 wherein the actuator is a lever to cause adjustment of the jaws between the locked and unlocked conditions.

9. A cookware assembly or set as claimed in claim 8 wherein the lever can articulate between at least two stable conditions, one of which positions corresponds to the locked condition of the jaw pair, the other corresponding to the unlocked condition of the jaw pair.

10. A cookware assembly or set as claimed in claim 9 wherein the articulation of the lever causes a sliding and/or otherwise guided member as a second jaw element to move relative to a more proximal fixed jaw element.

11. A cookware assembly or set as claimed in claim 10 wherein the lever has a cam profile that engages the sliding member, the arrangement being such that, via articulation of the lever, the cam profile can be pivoted outwardly from a condition that stably holds the sliding member in a locked condition closer to the first mentioned jaw yet allows the retreat of the sliding member to an unlocked condition under the action of a bias when the cam is moved or urged away from that condition.

12. A cookware assembly or set as claimed in claim 11 wherein the sliding member is biased towards the cam profile of the lever.

13. A cookware assembly or set as claimed in claim 6 wherein the jaw pair are shaped such that they are complementary with the attachment location of the cookware vessel to lock the handle to the vessel in a rigid, weight bearing manner.

14. A cookware assembly or set as claimed in claim 1, wherein:
the at least one cookware vessel is a plurality of cookware vessels, configured to be serially nested one within the other, in order of their size; and
the at least one lid assembly is a plurality of lid assemblies, wherein each lid assembly further comprises:
(a) a lid handle located substantially centrally of the lid body to provide a grippable region extending upwardly substantially beyond any part of the lid body, and
(b) a hollow region of the lid body located below the grippable region able to at least partly receive the grippable region of another one of the lids

the assembly or set being configured such that when the cookware vessels are serially nested, each vessel can seat its corresponding lid of the nested lids;
and wherein said selectively attachable handle is able to be held inside of the smallest of the cookware vessels when the vessels are serially nested.

15. A cookware assembly or set as claimed in claim 1 wherein said lid further comprises a moveable member carried by the lid, able to close over the vent relief when the handle is not so engaged so as to substantially weal the vessel.

16. A cook assembly or set as claimed in claim 1 wherein said lid further comprises a slideable member carried by and slideable relative to the lid body, able to close over the vent relief when the handle is not so engaged so as to substantially seal the vessel.

17. A cook assembly or set as claimed in claim 1 wherein said lid further comprises a moveable member carried by the lid, and able to encroach over the vent relief to reduce venting during cooking.
