Cooking or frying vessel or lid for this

Description:

The invention relates to a vessel for cooking or frying, with a vessel handle and with a pouring rim angled outwards from the vessel wall.

Such vessels, especially those intended for use in the home, are well known. One problem with such vessels is that the metal handles reach considerable temperatures and therefore cannot be grasped with unprotected hands.

This problem was attempted to be solved, for example, according to US-PS 1 093 227, by connecting the vessel handle, which is designed as a handle, to the pan wall via two lateral extensions and fastening sections. The fact that the lateral extensions of the handle allow air circulation is intended to make heat transfer from the pan wall to the handle more difficult. In the circumferential direction

However, the diagonally outward-pointing extensions of the handle are at a relatively large distance from the pan wall, so that the user can still burn himself at least when grasping these extensions.

In the cooking or frying vessel known from DE-PS 36 10 813, in which the vessel handle has a fastening section, a handling section and a cooling zone section provided between the fastening section and the handling section, the cooling zone section is arranged at such a small distance from the vessel wall that it is essentially parallel to it or only at a small angle to it, with the distance being in the range of 3 to 12 mm. Due to the special design of the vessel handle, burns are practically ruled out from the outset. The cooling zone section extends the heat conduction path to the handling section so that its temperature remains relatively low and therefore bearable. On the other hand, the distance of the cooling zone section from the vessel wall is chosen in such a way that it does not appear to be a handling section for optical reasons and is therefore not touched inadvertently. In particular, the maximum distance between the vessel wall and the cooling zone section is so small that the fingers of the human hand cannot fit between the wall and the cooling zone section and therefore there is practically no possibility of attack. The minimum distance, on the other hand, is chosen so that a kitchen towel can still fit between the vessel wall and the cooling zone section for cleaning purposes and that the radiant heat transmitted by the vessel wall is limited.

The problem of hot container handles has also been addressed by making them out of a material with low thermal conductivity, such as plastic, instead of metal. However, this increases the manufacturing effort. In addition, such plastic handles suffer from the high heat when the container is used in the oven or from the attack of detergents when cleaned in the dishwasher. Due to these circumstances, plastic handles become cracked, brittle and unsightly after a longer or shorter period of time.

The object of the present invention is to create a vessel of the type mentioned at the outset, in which the vessel handles are designed in such a way that they remain at tolerable temperatures while avoiding the disadvantages of the prior art mentioned.

This object is essentially achieved according to the invention in that the pouring rim is formed into a vessel handle in at least one peripheral region, preferably in two opposing peripheral regions, preferably by widening, and is provided with openings in these peripheral regions.

Such a vessel is easy to manufacture because the vessel handles do not have to be manufactured separately and attached to the vessel wall. They can be punched and formed at the same time as the pouring rim, since they are merely extensions of the pouring rim. Excessive temperatures of the vessel handles are avoided by the

Heat conduction from the vessel wall via the inner actual pouring edge section into the handle section on the outside is significantly hindered by the openings. The openings also allow cooling air to flow through. The vessel is easy to clean, and no rinsing water remains in any joints. The vessel is also suitable for use on gas stoves and is easy to recycle.

The peripheral areas of the pouring rim that form the vessel handles can be provided with a gripping recess or opening in order to be able to grasp and hold the vessel securely.

The openings serve their purpose particularly well when they are designed as slots running around the circumference of the pouring rim. This largely prevents heat conduction to the handle sections without the stability of the pouring rim in the circumference area of the vessel handles suffering too much.

In a further development of this idea, the openings are preferably arranged on circular arcs that are radially offset from one another in the circumferential direction and with a gap between them. In this way, several rows of openings can hinder the heat conduction to the handle sections.

The slots preferably have a circumferential length of about 15° to 25°, a radial width of about 2 to 5 mm and a circumferential spacing of about 2° to 10°. These dimensions allow optimal results to be achieved for most materials and material thicknesses that are usually used in the manufacture of cooking and frying vessels.

According to a further development of the invention, the peripheral areas of the pouring rim having the openings have a peripheral length of approximately 45° to 145°, while the preferably widened peripheral areas of the pouring rim forming the vessel handles have a peripheral length of approximately 20° to 120°. This makes the vessel handles easy to handle and at the same time, due to the fact that the peripheral area of the pouring rim having the openings has a larger peripheral length than that of the handle sections themselves, the conduction of heat from neighboring areas of the pouring rim to the actual handle area is also significantly hindered.

A further preferred feature of the invention is that the openings are provided in the peripheral areas of the flat section of the pouring rim, which is angled outwards essentially perpendicularly from the vessel wall, to which the sections forming the vessel handles are connected on the outside. The handle sections themselves therefore do not need to have openings but can be available over their entire surface for handling the vessel - possibly provided with knobs to prevent slipping and to reduce the surface contact between the handle and the hand.

The invention further preferably provides that the flat section of the pouring rim, which is angled outwards essentially perpendicularly from the vessel wall, is angled outwards from the preferably widened peripheral areas forming the vessel handles at an obtuse angle towards the underside of the vessel. This means that the handle sections are easy to hold on the one hand, and on the other hand it is easier to lift the lid, especially if a lid is used whose handles are also designed as extensions of the flat

lid edge, as explained in more detail below.

In this case, the gripping recesses or openings are preferably located in the area of the downwardly angled sections of the pouring rim, so that it is already visually visible that the vessel is only gripped in those sections where it has the lowest temperature.

If the cooking or frying vessel is equipped with a lid, the problem underlying the invention of excessive heating of the lid handle or handles can be solved in the same way and with the same advantages as with the vessel handles themselves. This applies in particular if the lid is equipped with a lid edge for contact with the pouring rim. In this case, the invention provides that the lid edge is formed into a lid handle in at least one peripheral area, preferably in two opposite peripheral areas, preferably by widening, and is provided with openings in this peripheral area. With regard to the advantages achieved here, reference can be made to the above statements regarding the handle design on the vessel itself. Such a lid can also be used as a serving bowl.

In this context, it is advantageous if the peripheral contour of the edge of the lid, even in the peripheral areas forming the lid handles, essentially corresponds to the peripheral contour of the pouring rim and/or the openings essentially correspond to the openings in the pouring rim in terms of position, shape, distribution and/or size. This means that the lid fits almost flush with the shape of the cooking or roasting vessel. The vessel and lid can therefore be easily grasped together using the handle sections assigned to one another.

According to a further advantageous embodiment, the peripheral areas of the lid edge forming the lid handles are provided with handle curvatures or openings pointing, for example, towards the underside of the lid, corresponding to the position of the grip recesses or openings of the pouring rim, whereby the lid can also be securely grasped and handled.

The flat section of the edge of the lid, which is angled outwards essentially perpendicularly from the lid wall, can be angled at an obtuse angle towards the top of the lid in the preferably widened peripheral areas forming the lid handles. This makes it easier to grasp the handle sections of the lid in order to remove the lid, especially if the corresponding handle sections of the vessel are angled towards the bottom of the pot.

The handle curves or openings are preferably provided in the areas of the upwardly angled sections of the lid edge. This provides a visual indication that the lid is only being touched in those sections, namely the handle sections, where it has the lowest temperature.

Furthermore, the edge of the lid can be curved over at least one peripheral region between the lid handles, preferably offset by 90° to the handle sections, relative to the lid plane in the direction of the top of the lid, for example in order to leave a pouring opening and/or vent opening between the pouring rim and the edge of the lid.

While the simplest design of the vessel and lid according to the invention is that in which both the vessel (apart from the base construction) and the lid are each formed in one piece, this does not of course prevent the implementation of the invention if the handle sections are made of a plastic material or are provided with a plastic material, if in any case the flat section of the pouring edge lying between the handle section and the vessel wall is provided with the openings to reduce the temperature of the handle sections.

Further aims, features, advantages and possible applications of the present invention emerge from the following description of embodiments based on the drawing. All described and/or illustrated features form the subject matter of the present invention on their own or in any meaningful combination, regardless of their summary in the claims or their reference back to them.

The vessel 10 for cooking or frying shown in Figs. 1 to 3 has a vessel body formed from a vessel wall 16 and a vessel base 26. At the upper end, a pouring rim 18 is angled outwards from the vessel wall 16. The pouring rim 18 has a peripheral edge section 30 that is essentially perpendicular to the vessel axis and is widened in two diametrically opposite peripheral areas to form a vessel handle 14, which in this way forms a section of the pouring rim 18. As can be seen from Figs. 1 and 2, the vessel handles 14 are angled downwards at an obtuse angle to the edge section 30, i.e. in the direction of the bottom of the pot. In the area of the vessel handles 14, an engagement recess 28 is provided that forms a lower depression. As can be seen from Fig. 2 and 3 in the peripheral areas of the edge section

30 of the pouring rim 18, which connect the vessel wall 16 to the respective vessel handle 14, slit-shaped openings 32 are provided. The slits run in the circumferential direction of the pouring rim 18, they are arranged on two radially offset circular arcs at a circumferential distance from one another and with a gap between them. The slits have a circumferential length of approximately 20 ^cm , a radial width of approximately 3 mm and a circumferential distance of approximately 3 °. The circumferential area of the edge section 30 of the pouring rim 18 having the openings has a circumferential length of approximately 90 ° in the embodiment shown, the engagement recess 28 has a circumferential length of approximately 40 °.

The lid 12 shown in Figs. 4 to 8 has a similar edge design to that of the vessel 10. The lid wall 24 has a circumferential bead 36 on the hood-like middle part, which fits into the opening of the vessel body. The lid wall 24 is then angled to form a lid edge 22 for large-area contact with the pouring edge 18 of the vessel 10. The lid edge 22 has a substantially flat circumferential edge section 40. The edge section 40 is widened to form a lid handle 20 in two diametrically opposed peripheral areas. As can be seen in particular from Fig. 6, the respective lid handle 20 is angled upwards at an obtuse angle /\J relative to the flat edge section 40, i.e. towards the top of the lid. The lid handles 20 are equipped with handle curves 38 which form upward-facing depressions.

In the edge section 40 between the lid wall 24 and the lid handle 20 there are slot-like openings 34 similar to the openings 32 of the edge section 30 of the pouring rim 18

provided. If the openings 34 of the edge section 40 are in line with the openings 32 of the edge section 30 when the lid 12 is placed on the vessel 10, no heat can accumulate under the handles 14, 20, which means that the handles 14, 20 remain relatively cold.

If the handles 14, 20 are aligned with the lid 12 placed on the vessel 10, the vessel 10 and lid 12 can be conveniently handled together because the corresponding handles 14, 20 can be grasped together with one hand due to their flat design. The aligned openings 32, 34 have the additional advantage that steam escaping from the side of the vessel 10 in the area of the handles 14, 20 does not flow outwards via the handles 14, 20, but can evaporate upwards through the openings 34, supported by the air flowing in from below.

As can be seen from Fig. 4, 5, 7 and 8, the lid edge 22 is provided with a bulge 42 over a certain peripheral area. This is formed, as can be seen in particular from Fig. 7, by an edge section 44 which adjoins the bead 36 and which is inclined upwards by a small angle V^ relative to the (horizontal) lid plane, i.e. towards the top of the lid 12. The edge section 44, which in its width corresponds essentially to the width of the otherwise flat edge section 40, is adjoined to the outside by a further narrower edge section 46 which is angled upwards by an obtuse angle fi relative to the edge section 44 and which extends into the wider

Lid handle 20. The bulges 42 can be provided diametrically opposite one another between the handles 20, offset by 90° to them, and promote the pouring off of cooking liquid and/or ventilation or the escape of steam.
