DETAILED DESCRIPTION

[0042] FIG. 1 generally represents a strainer dish 1 which is presently composed of a receiving container 2, at least one handle 3 and a lid 4. The strainer dish 1 and, resp., the handle 3 mounted thereon of FIG. 1 is in the removal position E, as can be seen from the projecting handle 3.

[0043] According to the invention, the removal position, i.e. the preferred vertical projection of the handle 3 out of the receiving container 2, is caused automatically after appropriately actuating a releasable holding element 5 (not shown in FIG. 1, cf. FIG. 4 or 5). For this purpose, in the portion denoted with II in FIG. 1 a spring element urging the handle and, resp., the handle bracket 3 thereof into the (swiveled-out) (removal) position.

[0044] An exemplary embodiment of the spring element in portion II is schematically indicated in FIG. 2. Here a leg spring 6 including a fixed leg 7 and a moving leg 8 is interposed between the handle/handle bracket 3 and the receiving container 2. Said two legs 7, 8 are biased (as is common for a leg spring) against each other via a winding portion. Said bias reaches a maximum when the two legs extend in parallel to each other, as shown in FIG. 2.

[0045] As soon as the releasable holding element 5 is actuated by a user, it releases the handle bracket 3 in its locking position, whereupon the bias of the leg spring 6 shifts the handle/handle bracket 3 from a locking position V (cf. FIGS. 4 and 5) into the removal position E. During such transition/shifting, the angle between the fixed leg 7 and the moving leg 8 is continuously increasing (and consequently the spring force is decreasing).

[0046] As shown in FIG. 3, for example, the fixed leg 7 is retained in its position while the moving leg 8 travels away from the former.

[0047] The leg spring 6 is arranged, for example, in the area of a handle joint 9 of the handle according to the invention. The fixed leg 7 has to be coupled to the receiving container 2, while the moving leg 8 is tightly connected to the handle/handle bracket 3, so as to reliably shift the latter from the locking position V into the removal position E.

[0048] The solution according to the invention is not limited to the now illustrated leg spring. Instead, also other types of springs such as flexible springs, preferably leaf springs, spiral springs or e.g. torsion springs, preferably rod springs, coil springs, can be employed.

[0049] In FIG. 3, the moving leg 8 is rotated about approximately 45 from the fixed leg 7. In the final removal position E, the angle between the moving leg 8 and the fixed leg 7 is approximately 90. This brings about optimum accessibility of the handle 3 in the removal position E. By a preferred degressive characteristic line of the leg spring 6, the first 45 are covered more quickly than the second 45.

[0050] FIG. 4 illustrates the strainer dish 1 with the receiving container 2 and the handle/handle bracket 3 being in the locking position V. The handle 3 is bracket-shaped and extends complementarily to a front face/narrow sidewall 10 of the receiving container 2. The front face/narrow sidewall 10 forms, together with a lateral surface/wide sidewall 11 and a bottom 12 of the receiving container 2, the rectangular basic shape thereof.

[0051] In the locking position, the bracket-type handle 3 adapts to the associated front face 10 while making at least in portions abutting contact and is mounted in/on the lateral surface 11 by the handle joint 9. Consequently, the interior space of the receiving container 2 can be optimally utilized.

[0052] In FIG. 4, the releasable holding element 5 is a slide 13 movable in the direction of one of the lateral surfaces 11 which is mounted on an outer side of the front face 10. The slide 13 is spring-biased to be movable along the function line 14 which is oriented along/in parallel to the handle bracket 3 located in the locking position. The corresponding spring responsible for the spring bias is not shown in FIG. 4; it may be a simple helical compression spring, however. The handle/handle bracket 3 can be divided into a holding portion 15 and a gripping portion 16, the holding portion 15 extending at the two longitudinally spaced ends of the gripping portion 16 substantially at right angles and at its free end having a functional portion (e.g. a clearance hole) which is pivotally coupled to the joint 9. Moreover, in the gripping portion 16 of the gripping bracket 3 an undercut is formed/provided which is operatively engaged in the slide 13 in order to retain the handle bracket 3 in the locking position against the spring bias of the (leg) spring 6.

[0053] As soon as the slide 13 is moved away from the gripping portion 16, the form closure between the handle bracket 3 and, resp., the undercut formed thereon and the slide 13 will loosen so that the leg spring 6 disposed in the area of the handle joint 9 attains an automatic movement of the handle into the removal position E (cf. FIG. 1). As long as the slide 13 is in form closure with the handle 3/with the undercut, the handle 3 remains in the locking position V of FIG. 4. Hence, simple pushing of the slide 13 causes the shifting from the locking position V into the removal position E.

[0054] FIG. 5 illustrates an alternative embodiment of the manually releasable holding element 5. In this case, the releasable holding element 5 is in the form of a clamping plate 17. Said clamping plate 17 constitutes a leaf spring interacting with the gripping portion 16 of the handle bracket 3 due to the bias of the plate. To this end, in the gripping portion 16 a bulge or through-opening 18 is arranged/formed which enables a form closure to be formed between the clamping plate 17 and the gripping portion 16.

[0055] As soon as the clamping plate 17 is pressed away from the gripping portion 16 along its function line 19, the form closure between the handle bracket 3 and the clamping plate 17 will loosen so that the leg spring 6 disposed in the area of/inside the handle joint 9 attains the automatic movement of the handle into the removal position E (cf. FIG. 1). As long as the clamping plate 17 is in the form closure with the handle 3 caused by the bulge 18, the handle 3 remains in the locking position V of FIG. 5. Simple pressing of the clamping plate 17 thus causes shifting from the locking position V into the removal position E.

[0056] In FIG. 6, another embodiment of the strainer dish 1 according to the invention is illustrated. The sidewalls 11 are schematically visible in the top view. The handle 3 is coupled to the receiving container 2 via the handle joint 9 or, resp., the handle joints in each of which a leg spring 6 is disposed.

[0057] According to the embodiment of FIG. 6, the lid 3 at least partially occupies the front face 11 of the strainer dish 1. This is made possible by the lid 3 swiveling outwardly away from the interior of the container after being linked to the handle joint 9. The inner volume of the receiving container 2 accessible for items/instruments is maximized in this way.
