For this purpose, the handbag according to FIGS. 5A and 5B and 5C is lined with a flexible or rigid thermal insulation layer 248 or 248 'or 248 ". The insulating layer delimits an interior space 228 or 228' or 228" for those in such a handbag 210 , 210 ', 210 "objects to be accommodated.

According to FIG. 5A, the insulating layer 248 is provided with a recess 247 at a point in the interior 228 of the handbag 210 into which a cooling unit 233 is inserted. The cooling unit 233 has a thermoelectric cooling block having at least one Peltier element 246, the warm side 250 of which faces the outer shell of the body 211 and the cold side 249 of which faces the interior 228 of the handbag 210. The thermoelectric cooling or Peltier element 246 is held stationary in the recess 247 of the insulating layer 248. The area of the outer shell of the body 211, against which the warm side 250 of the thermoelectric cooling element 246 rests, is, for example, porous or provided with a plurality of openings in a manner not shown. Depending on the material used for the body 211, its porosity may also be sufficient to dissipate the heat of the thermoelectric cooling element to the outside. Provided adjacent to the thermoelectric cooling element 246 is a connection socket 236 which penetrates the body 211 and is connected at its end facing the interior 228 to electrical lines of the thermoelectric cooling element 246. The connection socket 236 is designed in such a way that it can be connected to the normal electricity network via an intermediate cable, for example with a connection in a motor vehicle or via a converter.

In the exemplary embodiment shown in FIG. 5B, a recess 247 'of the insulating layer 248' is provided in a side area in the interior 228 ^/ the handbag 210 ', in which a recess coupled to a battery unit 234 * " Cooling unit 233 'is removably arranged. For this purpose, for example, two thermoelectric cooling elements 246 'are arranged opposite one another and are removably connected to the battery unit 234' by means of plugs 258 '. The battery unit 234 'expediently has a housing 259' with exchangeable batteries 260 'held therein. The battery unit 234 'and the thermoelectric cooling elements 246' can either be removed separately or together. In this exemplary embodiment, too, the warm side 250 'of the cooling elements 246' faces the outer shell of the body 211 'of the handbag 210', while the cold side 249 'of the thermoelectric elements 246' faces the interior 228 'of the handbag 210'.

With the variant of the handbag 210 "shown in FIG. 5C, as with the cosmetic case 110 in FIG. 2, the warm side 250" is arranged beyond the outer shell and the insulating layer 248 "of the body 211" in comparison to the variant in FIG. 5A. In this exemplary embodiment too, the thermoelectric element or Peltier element 246 can be connected to an external voltage source in a manner not shown.

The measures according to the invention are also not shown in the case of bath or wash bags or pouches, cosmetic bags or pouches and the like. in order to protect not only medication but also cosmetics in the amount of daily needs or the amount needed for a short trip from spoiling due to heat.

The small bag or the small bag can contain a body 211 or 211 'or 211 "made of any material, such as leather, fabric or the like. The insulating layer 248, 248' or 248" can be flexible or rigid and it can in particular also be designed or arranged to be removable. According to a further exemplary embodiment of the present invention, not shown, the thermoelectric cooling element or elements can also be provided in a separate compartment of the bag or pouch. This compartment inside the bag or pouch can accommodate not only the cooling unit, but also the objects to be protected. In this way, the other objects remain unaffected by the cooling unit, which has the further advantage that it may be sufficient to provide only this compartment with insulation. This possibility is indicated in FIGS. 5A and 5C in broken lines, which represent an insulating partition wall 265, 265 ", which delimits a receiving space part 264, 264" in which the cold side 249, 249 "of the thermoelectric cooling element 233, 233" and the objects to be cooled are accommodated. In this way, the remaining part of the interior of the interior 228, 228 "lying outside the part 264, 264" need not be lined with an insulating layer.

The small case shown in FIGS. 6 to 8 and serving as a doctor's case or emergency case 310 essentially consists of two case parts 311 and 312 of different lengths or depths, which can be separated from one another via a division level 313. Both case parts 311 and 312 are detachably connected to one another via a hinge 314 designed as a pivoting device. On the side surface opposite the hinge 314, each case part 311 or 312 is provided with part of a locking device 316. The two case parts 311 and 312 can be connected to one another via the locking device 316, as shown in FIG. 6B, so that they can be handled uniformly as a case 310. On the upper side 366, the longer case part 311 is provided near the division level 313 with a handle 315, via which the case 310 can be transported. The shorter case part 312 has a receiving space 327, which occupies its entire interior, which is accessible from the parting plane 313 and is inserted into the four identical drawers 362. The longer case part 311 has two superposed receiving spaces 326 and 330, of which the larger and lower receiving space 326 is equipped with two drawers 361 and the smaller and upper receiving space 330 is equipped with a cooling unit 333. Similar to a drawer, this cooling unit 333 can be inserted into this receiving space 363, but it can also be an integral part of the case part 311.

The receiving space 330 for the cooling unit 333 extends below the upper side 366 of the longer case part 311 of the case 310 over its entire cross-sectional area. In the exemplary embodiment shown, the cooling unit 333 is combined with a fan 370 which is arranged parallel to the cooling unit 333 within the receiving space 330. The receiving space 330, which is shielded from the lower receiving space 326 by a heat insulation base 369, is largely filled by a heat insulation body 368, in whose lower and upper recesses 372, 371 the cooling unit 333 and the fan 370 are arranged. FIG. 6B shows a plug socket 336 with which both the cooling unit 333 and the fan 370 are connected and with which an external voltage source, for example in a motor vehicle, in the doctor's office or the like. can be connected.

According to FIG. 8, the cooling unit 333 is designed like the cooling unit 133 according to FIGS. 2 and 3. In other words, in the wall part 367 of the insulation body 368 located between the recesses 371 and 372, a Peltier element 346 is integrated or inserted into an opening 347, on the upper warm side of which a Waste heat transfer element 350 and on its lower cold side a cold transfer element 349 is arranged. In the exemplary embodiment, the Peltier element 346, which is thinner than the thickness of the wall part 367, is directly connected to the waste heat transfer element 350, while on the cold side between the

Cold transmission element 349 and the Peltier element 346, a bridge 353 which produces "cold" transmission over a large area. The elements 350 and 349 are rib components 351, 352.

According to FIG. 7, the fan 370 has a fan motor 373 which is arranged in an opening 374 in the wall part 367. The fan motor 373 has two output shafts 375, 376 rotating in the same direction, on each of which a fan wheel 377 and 378 is held in a rotationally fixed manner. The upper diameter fan wheel 377 in FIG. 7 lies in the same upper space 371 between the upper side 366 and the wall part 367 as the waste heat transmission element 350. In contrast, both that lies in the lower space 372 between the wall part 367 and the insulating floor 369 to the adjacent or underlying receiving space 326 lower smaller diameter fan wheel 378 and the cold transfer element 349, in the area of which the insulating base 369 has a through hole 379 corresponding to the fan wheel diameter. Thus, the lower fan wheel 378 of the fan 370 distributes the air flow from the cold side 350 of the cooling unit 333 through the bore 379 to the receiving space 326, while the upper fan wheel 377, which is located immediately below an opening 381 covered with a grille in the upper side 366 of the case part 311 is arranged, by sucking in outside air through this opening 381 and expressing the warm air through an opening 382 covered by a grid in a rear wall 383 of the case part 311, for dissipating the waste heat. Since the upper space 371 connected to the two openings 381 and 382 is isolated from the lower space 372, a higher one can be used Temperature difference within the longer case 311 can be reached. The opening 381 in the top 366 of the case part 311 is in the exemplary embodiment directly between the pivot bearings of the handle 320. When the doctor's or emergency case 310 is closed, the temperature reduction can also be brought into the shorter case part 312 with the aid of the cooling unit 333 and the fan 370.

FIGS. 9 and 10 show a small case 410 of the type that is suitable, for example, for diabetics. The small case 410, which is also composed of a lower part 411 and a lid part 412 hinged to it, has a combined unit consisting of cooling unit 433 and fan 470 immediately adjacent to the inside of the rear wall 423. This unit 433, 470 is on the inside of a hood-like component attached, which forms the flat heat transfer element 449 here. The hood-shaped component 449 has a base area corresponding to the rear wall 423 and a depth which only makes up a fraction of the narrow side 495 of the lower part 411. As a result, the unit itself forms an intermediate wall 467, the side facing the interior of the small case is the cold side and the side facing the rear wall 423 and thus the outside atmosphere is the waste heat side.

FIG. 10 shows the arrangement of the combined unit 433, 470. The hood-shaped component serving as the cold transfer element 449 is formed from thin sheet metal, preferably aluminum, and has a flat plate 486 running parallel to the rear wall 423, which on its long sides and on its side Has top side bent at right angles to the rear wall 423 of the small case 410 longitudinal strips 487, 488. The upper longitudinal strip 488 serves as a cover for the cooling unit 433 and the fan 470. The inside of the flat plate 486 has an insulating layer 448 designed, which is provided at one point with a recess, not shown in detail, in which a Peltier element 446 is inserted. As in the exemplary embodiment in FIG. 3, the Peltier element 446 is laid flat with its cold side on the inside of the flat plate 486 of the cold transfer element 449 for good "cold" transfer, while its warm side is connected to a waste heat transfer element 450, which is also here is designed as a rib component, the ribs 451 of which run parallel to the longitudinal strip 488 of the flat cold transfer element 449.

One end of the rib component of the

Exhaust heat transfer element 450 is located immediately adjacent to a radial exhaust port 491 of the fan 470. The fan 470 is designed such that the fan wheel 477 blows out radially, but sucks in axially. For this purpose, an annular space 493 is provided between the fan wheel 477 or its drive shaft 475 and the fan housing 492.

In the installed position of the combined unit 433, 470 within the small case 410, the fan 470 sucks in outside air via openings 481 in the rear wall 423 and presses it through the channels running between the ribs 451 of the rib component. The air heated at the waste heat transfer element 450 reaches the outside via openings 482 in one side wall 495 of the lower part 411. For a more favorable guidance of the waste air and the more favorable insulation, an essential area of the ribs 451 facing the fan 470 is covered on the surface with an insulating layer 496.

The cooling unit 433 and fan 470 are supplied with power either via an external or an internal voltage source.
