Description

[Detailed description of the invention]

0001

FIELD OF INDUSTRIAL APPLICATION The present invention relates to a container made of ceramic, glass or plastic for containing food, etc., and a generally flat circumferential container having two mutually opposed container tabs bent outward from the container wall. The present invention relates to a household tableware, in particular for use in a microwave device, having a rim and a lid, the lid rim of which can be placed on the container rim for closure.

0002

BACKGROUND OF THE INVENTION Such tableware is known.

0003

OBJECTS OF THE INVENTION It is an object of the present invention to improve such tableware so that the lid not only closes completely, but also leaves an opening for ventilation or vapor escape when placed on the container. The goal is to make it possible.

0004

According to the invention, one or more elevations or recesses are provided on the upper side of the container rim in one of the edge areas between the container tabs. , the lower surface of the lid rim is provided with one or more recesses or ridges complementary to this ridge or recess, and on the upper surface of the container rim or the lower surface of the lid rim, on the side opposite to the recesses, the ridges are provided. A complementary ventilation cutout is provided.

[0005]

This makes it possible to place the lid on the container in at least two different positions. In one position, a ridge on the container rim or lid rim overlaps a complementary recess in the lid rim or container rim, so that the ridge and the recess engage each other and, except for the open ventilation notch, the lid The lower surface of the lid rim rests on the upper surface of the container rim to close the container. This is the so-called ventilation rotation position of the lid. However, if the lid is placed on the container rim with an angle of displacement of, for example, 180°, the container rim or the bulge on the lid rim engages in a suitably formed ventilation cutout in the lid rim or container rim. By closing this ventilation recess and resting the lid rim on the container rim in other areas, the inner space of the dish is completely closed off. This is the so-called closed rotation position of the lid. Such means according to the invention are easily manufactured and do not change the appearance or function of the tableware. By providing a ridge on the edge of the container,
Since the ventilation recess is located in or comes to the edge area between the container tabs, handling of the tableware is not hindered by the escaping steam.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The elevations or depressions can be designed, for example, as straight or curved fins or grooves.

In order to ensure complete closure of the utensil in the closed rotational position of the lid, the ridge and recess preferably have the same circumferential dimensions, but as long as the ridge fits snugly into the recess, the ridge can be replaced with a complementary one. It can be shorter than the recess.

[0008] Advantageously, the elevation is provided on the container rim and the recess is provided on the lid rim.

[0009] It is likewise proposed according to the invention that the ventilation recesses are provided preferably in the lid rim.

[0010] In order to clearly define the closing and opening rotational positions of the lid, a further development of the invention provides that the container tab is configured at least partly as a tab part of the container rim;
In order to protrude from the rest of the container rim and position the lid on the container, the lid rim is cut out or shortened in the area of the container tab. In this way, the lid is placed on the container, for example, in only two rotational positions, so that the lid always assumes the desired closing rotational position or venting rotational position.

For this purpose, it can be provided that the lid rim, preferably in the area of its recess or shortening, rests against the inner edge of a step provided on the container handle or container rim. This prevents, for example, the lid from sliding sideways out of the container.

If two container tabs are provided on opposite sides of the container and the inner edge of the container tab or step extends symmetrically with respect to the vertical central plane of the container, it is possible to rotate the lid by 180°. This makes it possible to move this lid from the closed rotation position to the ventilation rotation position or vice versa, making handling of the tableware according to the invention particularly simple.

According to another embodiment of the invention, the container wall has a circumferential slope, except in the area of the container handle, which transitions into an approximately vertical surface. As a result, a rim area is created between the container handles for a directional outflow of cooking liquid or food product, so that handling of the container is not hindered when the container handles are grasped.

In order to center the lid on the container, the lid follows the lid rim with a circumferential slope complementary to the slope of the container wall, except in the area of the container knob where it transitions to an approximately vertical surface. It is advantageous to have it.

[0015] The container handle is constructed as a thickened part of the handle part of the container rim, or the handle part of the container rim has a cover or a handle element which is attached to the container rim, and the cover or the container handle is preferably made of an insulating material, for example a heat-resistant material. When made of plastic, the container handles are well insulated and tableware is easily manufactured. Use different colors for the material of the container knob.
The container handle, which does not need to be much wider than the rest of the container edge, can be easily identified and the user can grasp only this thermally insulated area.

[0016] The tab element can be fitted, for example, onto the tab portion of the container rim. However, it is also possible to glue the gripping element to the gripping part or to weld it, for example by means of ultrasound.

[0017] Advantageously, there is a space between the knob element and the knob part, thereby improving the insulation effect. For this purpose, means are used which bring the handle element into contact with the container only at the point where it is clamped, glued or welded.

[0018] In order to improve the strength of the tab, the tab element is provided with, for example, a raised surface structure. This has the advantage that the gripping element grasped by the user does not come into complete contact with the user's skin, and a perfectly flat surface is interrupted by projections or other surface structures.

In order to improve the secure fixing of the lid on the container and the aesthetic appearance of the tableware, it is advantageous if the lid rim of the lid to be placed is flush with the container tab or grip element. . Thus, when handling the tableware container and the lid at the same time, the user's thumb can easily hold the lid on the container.

According to another embodiment of the invention, the lid has a lid tab which is formed by a tab on the lid rim and which protrudes, for example, from the container wall, so that it is possible to remove and place the lid without risk of burns. become.

If two lid tabs are provided, they should be on substantially diametrically opposite sides with respect to the axis of the lid.

In this case, according to the present invention, lid tabs are provided in the same direction following the notches or shortened portions of the lid edge, so that the lid is constructed centrally symmetrically, but is plane symmetrically with respect to its vertical central plane. Prevent it from being configured.

For the reasons mentioned above regarding the container handle, the lid handle can also have a raised surface structure, for example.

In order to be able to easily check the closing rotational position and the venting rotational position of the lid on the container from above, a further development of the invention provides that the exposed parts of the container rim when the lid is placed on the container, e.g. Continuous locating markings are provided on a portion of the knob and on a portion of the lid edge that is adjacent at one rotational position of the lid.

[0025] Food heated by microwave treatment is
It is often stored in a freezer or refrigerator for some length of time in advance. For this purpose, it is ensured that the internal space of the tableware is closed as tightly as possible. According to the invention, a further lid is therefore provided which is designed as a freezer lid. The lid can be mounted on the container, for example via a restraining coupling device that engages over the container rim. The restraining coupling device is preferably formed by the circumferential edge part of the freezer lid and has its inner contour adapted to the contour of the container edge.

[0026] The freezer lid preferably has a lip portion that engages over a tab portion on the lip of the container. Since the freezer lid is made of an elastic material such as plastic, it can be easily fitted onto the container and removed from it again.

Further objects, advantages and applicability of the invention will become apparent from the following description of an exemplary embodiment with the aid of the drawings. All the features described and illustrated here form the object of the invention, alone or in any combination, irrespective of their summary in the claims.

[0028]

[Embodiment] The tableware shown in FIGS. 1 to 4 or 5 to 7 includes a container 2 formed from a deep pot 2' or a shallow pot 2'', and a lid 40 (FIGS. 8 to 8) that can be placed on this container 2. 11). The container 2 has a container wall 4, a bottom 6, and a circumferential container rim 8 extending outwardly from the container wall 4 in a substantially flat manner. The transition from the container wall 4 to the bottom 6 is rounded. The width of the container rim 8 is increased to form two diametrically opposed container tabs 9, 10 which are configured as edge parts. As can be seen from the plan view of FIG. 1, the circumferential edge of the container edge 8 is slightly retracted (r1<r2) in the area of the edge forming the container knobs 9, 10, so that
When the tab elements 70, 72 shown in FIG. 1 are fitted onto the edge portions, the outer edges continue smoothly. The detailed construction of the knob elements can be seen from FIGS. 12 to 15. In the region of the edge portions forming the container tabs 9, 10, the container wall 4 extends upwards into an approximately vertical plane 21 (
3), and in the edge regions 11, 12 located therebetween, the container wall 4 is connected via the inclined surfaces 18, 20 to the edge regions 11, 1.
2, the width of the edge portions forming the container tabs 9, 10 is increased. This makes it possible to direct the cooking liquid or food product through the edge areas 11, 12 and thus as far as possible from the container tabs 9, 10.

A lid 4 according to FIGS. 8 to 11 is provided on the container rim 8.
0 lid edge 41 can be placed in two rotational positions offset by 180°. For this purpose, on the upper side of the container rim 8 in one rim region 11 between the container tabs 9, 10, a bulge 28 extending over a certain angular range and formed as a fin is provided.
are provided and the opposing edge areas 12 are flat. Lid rim 4
On the underside of 1 there is a recess 56 formed as a complementary groove in the same position and shape. On the underside of the edge area of the lid edge 41 facing the recess 56 there is a ventilation cutout 57 which extends radially inwardly and outwardly. This ventilation recess 57 has a circumferential dimension H equal to the circumferential dimension of the elevation 28 and the recess 56 in its radially inner region. In the radially outer region, this ventilation recess 57 is short and has only a circumferential dimension G. When the lid 40 is placed on the container 2 in the rotational position in which the ridge 28 of the container rim 8 engages the recess 56 of the lid rim 41,
With the lid 40 fully resting on the container rim 8, the interior of the container is completely closed except for the ventilation cutout 57. On the other hand, in the rotated position rotated by 180°, the ridge 28 is located in the ventilation notch 5.
7 to close this ventilation notch, and the container rim 8 and the lid rim 41 also touch each other to close over the other circumferential areas, so that the interior of the dish is completely closed. . The lid 40 can thus be easily transferred from the closed rotation position to the ventilation rotation position, which is advantageous, for example, when the tableware is used in a microwave oven.

If the container tabs 9, 10 are configured as a tab part of the container rim 8, they project in the height direction from the other part of the container rim 8 and have a separate tab element 70 on the tab part. , 72 are fitted, at least these tab elements project in the height direction from the upper surface of the other parts of the container rim 8, and as shown on the left side of FIG. Edges 13, 14 are formed and extend linearly approximately parallel to each other, as shown in FIG. The corresponding outer edges 15, 16 of the lid 40 are
1 cutouts or shortenings, which are also parallel to each other, so that the lid 40 fits snugly between the inner edges 13, 14. Thereby, the lid 40 can be attached to the container 2 only in two predetermined rotational positions, namely the closed rotational position and the ventilation rotational position.
You can put it on. Container knobs 9, 10 or stepped portion 1
The inner edges 13, 14 of the container 2 extend symmetrically with respect to the vertical center plane M of the container 2, so that the outer edges 15, 16 of the lid edge 41 are connected to the container knobs 9, 10 or steps in the area of the cutout or shortening. This corresponds to the inner edges 13 and 14 of the portion 17.

As can be seen in FIGS. 8 to 11, the lid 40, following the lid rim 41, transitions into a vertical surface 45 which is complementary to the inclined surfaces 18, 20 of the container wall 4 and in the area of the container tabs 9, 10. It has rotating inclined surfaces 48 and 50. This centers the lid 40 on the container 2 and ensures a secure closure, so that no steam escapes at all or only through the ventilation cutout 57, thereby avoiding injury to the user's hands. There is no.

The container tabs 9, 10 can be formed as thick material parts of the container edge 8 in the tab area, so that their temperature is kept relatively low; however, the tabs may be provided with thermally insulating areas or the tab elements 70 , 72 can be made from a thermally insulating material such as plastic. The knob part itself or the covering of the knob part or the knob element itself should preferably be attached to the container edge 8.
The knob range can be easily identified because it has a different color from the other parts. Knob elements 70, 72
The installation can be carried out by a simple press fit, ensuring a sufficient press fit. However, alternatively or in addition, it is also possible to glue or ultrasonically weld the tab elements 70, 72 to the tab parts of the container rim 8 to ensure a permanent fixation. A space may be provided between the knob elements 70, 72 and the knob portion to further improve the insulation effect. Note that the knob elements 70 and 72 are brought into contact with the container 2 only at the locations where they are to be tightened, bonded, or welded.
Heat transfer from the container wall 4 to the container knobs 9, 10 is minimized. As can be seen in FIGS. 12-15, the grip elements 70, 72 preferably have a protruding surface structure to increase grip strength and reduce heat transfer to the human hand.

As can be seen from FIG. 16, the top surface of the lid rim 41 of the lid 40 placed on the container 2 is the top surface of the container knobs 9, 10, or in the case of the figure, the fitted knob element 7.
It has a thickness so that it forms a surface at the same height as the top surface of 0.72. As can be seen from this figure and from FIGS. 8 to 11, the lid 40 has a central recess 51 for inserting another container 2, thereby improving the stackability of the tableware.

In the illustrated example, the lid 40 has lid tabs 42, 44 configured as tabs on a lid rim 41, these lid tabs being on substantially diametrically opposite sides with respect to the lid axis and located on the lid rim 41. 41 notches or shortenings, respectively. Since the lid tabs 42, 44 project radially from the container edge 8, they can be easily grasped. The lid tabs 42, 44 similarly have, for example, a protruding surface structure. If the lid 40 is made of plastic and therefore of a thermally insulating material, no special thermal insulation is necessary in the area of the lid tabs 42, 44 by means of a coating or special tab elements, which also applies to the tab area of the container 2 itself. I can say that.

As can be seen from FIG. 16, the exposed portion of the container rim 8 when the lid 40 is placed, the knob portion formed by the container rim 8 in the figure, and the portion of the lid rim 41 in the illustrated rotational position of the lid 40. Position confirmation markers 60 complementary to each other are provided in adjacent portions. When this locating mark 60 is complete, it indicates the closed rotational position of the lid 40. In the 180° vent rotation position of the lid 40, both portions of the locating mark 60 are diametrically opposed, so that the user can easily confirm that the lid 40 is in the vent rotation position.

[0036] When such tableware is used in a microwave device, food is often stored in a refrigerator or freezer for a long time. For this purpose, the container 2 can be closed airtight. To this end, the freezer lid 90 shown in FIGS. 17 to 26
Two examples are used. This freezer lid 90 can be attached to the container 2 by means of a restraining coupling device 92 that engages on the container rim 8 . This restraining connection device 92 is formed by the circumferential edge section of the freezer lid 90 , whose inner contour is adapted to the loop of the container edge 8 . Also engaged on the tab portion of the container rim 8 is a rim portion 100 which is raised for this purpose. Since the freezer lid 90 is preferably made of an elastic material, it can be simply pressed onto the container 2 and removed from there again. For centering and restraint of the restraint coupling device, the freezer lid 90 has a relatively stiff orbiting support fin 94 parallel to an outer wall 96 of elastic construction. A rounded projection 98 on the inside of the outer wall 96 ensures that the elastically deflecting outer wall 96 hooks under the container rim 8.
