The invention relates to a liquid container of the type mentioned in the preamble of claim 1.

Microwave ovens for heating and cooking food have now become widespread in large kitchens and also in private households. Since the metal cookware used for conventional food preparation cannot be used in a microwave oven, suitable containers have been developed for use in microwave ovens, which are usually made of plastic.

In these containers, food can be prepared in a microwave oven in a particularly gentle and energy-saving manner. In addition to preparing food, it is of course also possible to prepare hot water or drinks by heating them in a microwave oven.

A microwave jug made of borosilicate glass is known for preparing hot drinks, the container body of which has an opening that can be closed with a lid and a handle. Both the lid and the handle are made of plastic. The lid can be connected to the glass body in a form-fitting manner using locking tongues, and the handle is glued to the glass body at its ends, whereby a special adhesive technique for attaching the handle means that a metal band that is incompatible with microwaves is not required. To handle the lid,

HPlOl Page 9

a grip pin arranged centrally on the surface of the lid is provided.

The adoption of classic design features of a beverage container proves to be out of date in view of the ease of use that is generally common today. For example, removing the lid from the well-known microwave is not possible. len-Kanne is only possible if you accept the fact that

This object is solved by the characterizing feature of claim 1.

The solution according to the invention ensures a high level of operating comfort, safe handling and high durability and resilience of the handle and enables the container to be used in almost any microwave oven.

The lever-like design of the lid handle enables safe, lateral operation of the lid. The continuous transition into the handle protects the lid handle against accidental operation, since operating the lid handle requires it to be swiveled first in order to then be able to remove the lid from the container by pulling on the lid handle. The lever-like design of the lid handle also enables the lid handle to be flat and yet easy to grip. This therefore enables the container to be designed flat overall despite being easy to use.

According to an advantageous development of the invention, the handle merges into a fastening ring that at least partially surrounds the container body and is positively connected to the container body. Thanks to the positive connection, no complex adhesive technology is required and the durability of the handle fastening is ensured even after prolonged use. In addition, the easily detachable connection of the handle to the container body enables the handle to be easily removed, for example for cleaning purposes.

HPlOl Page 11

Advantageously, the handle is connected to the container body in the area of the upper edge. This additional fastening point, which is spaced apart from the fastening ring, creates a broad base for absorbing the weight moment through the handle.

According to another advantageous feature, the handle is positively connected to the upper edge of the glass bulb in its free end cross-section by means of a clamping lug. This design of the positive connection, together with the fastening ring that positively encloses the container body, enables a particularly easy-to-use connection that ensures uncomplicated attachment and removal of the handle.

Advantageously, the container body is made of glass and the fastening ring with the handle attached to it as well as the lid with the lid handle attached to it are made of plastic. The container body made of glass enables the container to be cleaned particularly thoroughly, and the plastic parts are characterized by poor heat conductivity, which prevents the plastic parts that are handled when operating the kettle from heating up.

The lid handle has the same radius of curvature as the handle, which extends from the fastening ring to the lid with a constant curvature. The lid handle and the handle have an identical cross-section, which is also the case in a transition area, in which the lid handle and the handle are in-

grip each other. As a result, the handle and the lid handle connected to it form a unit on the outside, which, in addition to the advantage that the lid handle can only be operated after it has been swivelled sideways, also has an attractive design.

According to a further advantageous embodiment, the cross-section of the lid handle and the handle is circular and has slats connected to one another by a central bar. In addition to good grip, this results in a lightweight, material-saving design.

In the transition area between the lid handle and the handle, the latter are separated from each other by a separating joint which runs in at least one plane and which is formed by two counter surfaces of the lid handle and the handle arranged parallel to each other.

In a preferred embodiment, the separating line runs essentially in a plane parallel to and immediately adjacent to the upper edge of the container body. This allows the lid handle to be pivoted in any direction on either side in the plane of the upper edge of the container body, and the opening of the container is freely accessible from all sides by closing the handle at almost the same level as the upper edge when the lid is removed.

By a course of the parting line in two planes arranged perpendicular to each other, according to another preferred

HPlOl Page 13

In the embodiment of the invention, it is achieved that the lid handle can only be pivoted in a direction parallel to the upper edge of the container body, whereby a vertical counter surface of the handle then serves as a stop for the correct positioning of the lid handle relative to the handle.

In another embodiment, the separating joint is arranged vertically with its two parallel counter surfaces, whereby one counter surface has a hole and the other counter surface has a clamping extension corresponding to the hole. The clamping extension serves to advantageously secure the position of the lid handle positioned opposite the handle.

To ensure a positive connection to the container body, the fastening ring has locking tongues that engage behind bead-shaped thickenings on the container body. These thickenings are particularly easy to create when manufacturing a container body made of glass.

Further developments of the invention according to the following subclaims are explained in more detail below together with the preferred embodiments using the figures. They show:

Figure 14 shows an insert designed as a tea strainer;
Figure 15 the insert inserted into the lid and
Figure 16 shows the insert inserted into an insert ring.

Figure 1 shows a liquid container 1, which essentially consists of a container body 2, a lid 4 closing its opening 3 and a handle 6 connected to the container body 2 via a fastening ring 5. The lid 4 shown in Figure 2 has a lid handle 8 that extends essentially laterally from the lid base 7. This continuously merges into the handle 6 in a transition area 9, which has a separating joint 10 that separates the lid handle 8 from the handle 6.

According to Figure 3, the handle 6 has a clamping lug 12 in its end cross-section 11, which, in addition to the fastening ring 5, serves to form-fit the handle 6 to the container body 2. For this purpose, the clamping lug 12 is engaged on the upper edge 13 of the container body 2.

For the positive connection of the fastening ring 5 and the lid 4 to the container body 2, locking tongues 14, 15 are provided on the fastening ring 5 and locking tongues 16 on the lid 4.

The lid handle 8 and the handle 6 have the same

cross-section 17, which in the transition area 9 is formed by a corresponding design of the ends 18, 19 of the cover

HFlOl Page 16

handle 8 and the handle 6 complement each other. Only in the area of the upper edge 13 is there a constriction 20 of the cross-section 17 composed of the ends 18, 19 in the transition area 9. This constriction 20 ensures that the lid handle 8, which extends laterally from the lid, is guided as flat as possible over the upper edge 13 of the container body 2, so that the height of the container body 2 is only insignificantly increased by the lid handle 8.

The separating joint 10 in the transition area 9 is essentially limited by two parallel counter surfaces 21, 22 of the ends 18, 19 of the lid handle 8 and handle 6. The counter surface 21 of the handle 6 is almost level with the upper edge 13 of the container body 2. When the lid 4 is removed, the opening 3 of the container body 2 is thus freely accessible from all sides.

The combined cross-section 17 shown in Figure 4 in the transition area 9 enables unhindered pivoting of the lid handle 8 relative to the handle 6 in both directions parallel to the upper edge 13. After pivoting in one direction or the other, the lever-like design of the lid handle 8 can be used to easily open the liquid container 1 by applying a force acting vertically upwards in the area of the end 18. If the counter surfaces 21, 22 are arranged opposite one another, it is ensured that unintentional opening of the liquid container 1 is prevented. 30

Figures 5 and 6 show further preferred embodiments of the transition area 9. The cross-section of Figure 5

The transition area 9 shown consists of ends 23, '"■ 24 of the lid handle 8 and the handle 6, which

are separated from each other by a separating joint 25 running in two planes perpendicular to each other. This design of the transition area 9 has a through a t vertical counter surface 26 of the handle 6 formed

The locking extension 33 is arranged on a counter surface 34 at the end 28 of the lid handle 8 and, due to its curved surface, achieves

> 35 a clamp in the bore 32 which counteracts an unintentional pivoting of the lid handle 8 relative to the handle 6.

Figures 7 and 8 show the fastening ring S partially enclosing the container body 2. For easy lateral sliding onto the container body 2, the fastening ring 5 has a circumference that only slightly exceeds a semicircle, but which, in conjunction with the end regions of the circumference of the fastening ring,

HPlOl Page 18

5 arranged locking tongues 14, 15 enable a resilient positive connection with the container body 2. To increase the flexibility of the fastening ring 5, relief notches 38 are provided in stiffening webs 37 running horizontally on an inner side 36 of the fastening ring 5.

Figure 7 also shows the structure of the cross section 17 of the handle 6, which is designed in the same shape as the lid handle 8. The cross section 17 consists of slats 45 arranged parallel to one another, which are connected to one another in one piece via a common connecting web 46. The slats 45 have decreasing lengths towards the ends of the connecting web 46, such that a circular contour of the cross section 17 results.

The horizontally extending stiffening bars 37 are connected to each other by vertically extending stiffening bars

39 connected.
20

For the form-fitting connection of the locking tongues 14, 15 of the fastening ring 5, bead-shaped thickenings 40 are provided on the container body 2, so that when the fastening ring 5 is pushed sideways onto the container body 2 behind the locking tongues 14, 15 behind the thickenings

40. In this position, the fastening ring 5 rests with its stiffening webs 37, 39 on the container body 2. In order to achieve a secure positive connection between the fastening ring 5 and the container body 2 in the vertical direction of loading, the thickenings 40 are designed in such a way that they rest on the fastening ring

/19

HPlOl Page 19

laterally limiting, horizontal stiffening bars 37 .

To ensure safe force transmission from the handle 6 into the fastening ring 5 connected in one piece with it, a transition area 41 between the handle 6 and the fastening ring 5 is reinforced.

A special embodiment of the lid 4 provides for shoulders 43 arranged on the inside of a lid wall 42, which extend parallel to the lid base 7. This makes it possible to attach inserts to the lid 4 without hindering the lid function, namely the locking of the container 1.
15

Fig. 14 shows an insert designed as a tea strainer 47 with slots 63, which can be inserted into a correspondingly designed lid 48 according to Fig. 15.

The tea strainer 47 essentially consists of a receiving part 50 having a locking shoulder 49, which merges into a cup part 51 for holding tea or the like. To accommodate the tea strainer 47, the lid 48 is provided with an inner wall 52 in addition to the lid wall 42, in which locking tongues 53 are provided.

The locking tongues 53 have locking projections 54 which, when the tea strainer 47 is inserted into the lid 48, lock behind the locking shoulder 49 of the tea strainer 47. In order to clean the tea strainer 47, it can be removed from the lid 48 again after use against the resistance of the locking tongues 53.

HPlOl Page 20

By connecting the tea strainer 47 to the lid 48, the container 1 can be closed in a simple manner during tea preparation. In addition, the lid handle 8 can be used to insert and remove the tea strainer 47 from the container 1.

Fig. 16 shows another use of the tea strainer 47 in an insert ring 55 inserted into the container 1. The insert ring 55 essentially consists of a ring base 56, from which an outer wall 57 and an inner wall 58 extend vertically.

The outer wall 57 has locking tongues 59 with which the insert ring 55 is inserted into the container body 2 in a form-fitting manner. The inner wall 58 is provided with locking openings 60 and a support surface 61. The support surface 61 is designed in such a way that the tea strainer 47 inserted into the insert ring 55 from above rests with its locking shoulder 49 on the support surface 61.

The cover 62, which is designed in the same way as the covers 4, 48 except for a reduced outer diameter, is closed in a form-fitting manner. The locking tongues 16 of the cover 62 engage in the locking openings 60 of the inner wall 58 of the insert ring 55.

The use of the insert ring 55 offers the advantage

that, depending on requirements, the insert ring 55 and the tea strainer 47 can be handled as a complete unit via the lid 62, but also the tea strainer 47 can be

&bull;&diams;

HPlOl Page 21

can be inserted into the container 1 with the lid 62 removed.

Regardless of whether the insert designed as a tea strainer 47 is inserted into the lid 48 or the insert 55, there is in any case the advantage that by using the insert, pouring the water heated in the container 1 into the teapot is no longer necessary.

In order to avoid excess pressure in the container body 2 as a result of the heating of water, 7 rows of concentrically arranged holes 44 are provided in the cover base.

Of course, further designs of the container beyond the preferred embodiments described here are conceivable, in which use is made of the solution according to the invention.
