DETAILED DESCRIPTION OF THE DISCLOSURE

[0052] Shown in FIG. 1 in detail is a door 1 with a hermetically sealed insulating glass unit 2 as seen in a plan view of one of the two panes 2a, 2b of the insulating glass unit 2. The two panes 2a, 2b are joined with each other via vertical and horizontal spacers 3a-3d extending peripherally around the edge regions 6 of the panes 2a, 2b with formation of an intervening space. The spacers 3a-3d are transparent in design and, together with the pane 2a, form a transparent face 4a. Furthermore, a desiccant reservoir is within the transparent face 4a and is partly overlaid or covered up by a handle 7. In this case, “within” means within the face 4a and comprises both an arrangement within the intervening space as well as an arrangement outside of it, such as, for example, on the pane 2a. The desiccant reservoir 5 can also be designed itself as the handle 7. Depending on the particular design, the desiccant reservoir 5 is in fluidic contact with the intervening space between the two panes 2a, 2b of the door 1, for example, via holes (not shown) in the pane 2a.

[0053] Shown in FIG. 2 is essentially a door 1 in accordance with FIG. 1. In contrast to the door 1 of FIG. 1, in the case of the door 1 of FIG. 2, the desiccant reservoir 5, instead of being within the face formed by the spacers 3a-3d peripherally around it, is now outside of the face in the bottom region 8a of the door 1. The desiccant reservoir 5 thereby extends along the entire horizontal length of the door 1. The desiccant reservoir 5 is thereby in fluidic connection with the intervening space between the two panes 2a, 2b via connection apertures or channels 10.

[0054] Shown in FIG. 3 is essentially a door 1 in accordance with FIG. 1. In contrast to the door of FIG. 1, in the case of the door 1 of FIG. 3, two desiccant reservoirs 5a, 5b are now outside of the face 4a formed by the peripherally arranged spacers 3a-3d and the panes 2a, 2b. They are situated on the top side 8b and the bottom side 8a on the left side of the door 1 in FIG. 3. In this case, the spacers 3a, 3b, 3c, 3d are designed correspondingly to extend peripherally around the respective desiccant reservoir 5. Arranged on the top side 8b and the bottom side 8a, likewise on the left side of the door 1 in FIG. 3, are respective suspension mountings 22a, 22b, which serve for revolving the door around an axis 21. Then, if the handle is pulled, the door 1 opens by revolving around the axis 21. In this case, the two desiccant reservoirs 5a, 5b are arranged symmetrically in relation to a horizontal axis 20, which, in this case, is an axis of symmetry of the door 1. Via corresponding apertures or connection channels 10 in the spacers 3c, 3d, the two desiccant reservoirs 5a, 5b are in fluidic connection with the intervening space between the two panes 2a, 2b.

[0055] Shown in FIG. 4 is essentially a door 1 in accordance with FIG. 3. In contrast to the door 1 of FIG. 3, in the case of the door 1 of FIG. 4, the two desiccant reservoirs 5a, 5b are now within the face 4a formed by the panes 2a, 2b and the peripherally arranged spacers 3a-3d. For the sake of simplicity, the suspension mountings 22a, 22b, as also in the case of the other figures, are no longer depicted. It is conceivable in this case to arrange the desiccant reservoirs 5a, 5b within the intervening space between the two panes 2a, 2b as well as outside of the intervening space, such as, for example, on one of the panes 2a, but within the face bounded by the spacers 3a-3d.

[0056] Shown in FIG. 5 is substantially a door 1 in accordance with FIG. 1. In contrast to the door 1 of FIG. 1, in the case of the door 1 of FIG. 5, the desiccant reservoir 5 is now within the face 4a formed by the panes 2a, 2b and the peripherally arranged spacers 3a-3d. Furthermore, the desiccant reservoir 5 is on the top side 8b of the door 1. Arranged on the surface of the desiccant reservoir 5 is a display device 11 in order to cover up the desiccant reservoir 5. The display device 11 can be, for example, an imprinted film or the like, which, for example, has names of groups of products or the like for customer information. For the sake of simplicity, the suspension mountings 22a, 22b are once again not depicted. Corresponding to the design of FIG. 2, the desiccant reservoir 5 extends horizontally over the entire horizontal width of the door 1 between the two vertical spacers 3a, 3b.

[0057] Shown in detail in FIGS. 6 and 7 is substantially a door 1 in accordance with FIG. 5. In contrast to the door 1 of FIG. 5, in the case of the door 1 of FIGS. 6 and 7, the desiccant reservoir 5 is now on the bottom side 8a of the door 1 between the two panes 2a, 2b. Arranged on the surface of the desiccant reservoir 5 is a reflecting or imprinted decorative surface that extends obliquely in order to cover up the view of the desiccant reservoir 5.

[0058] As desiccant, it is possible to use, for example, molecular sieves or a combination with silica gel. Corresponding crystals have a mean pore size of between 3 and 10 Angstroms.

[0059] As material for the panes, it is possible to use, for example, glass and/or plastic.

[0060] As material for the spacers, it is possible to use, for example, transparent adhesives, resins, or the like.

[0061] In summary, at least one of the embodiments of the disclosure has at least one of the following advantages: [0062] long service life [0063] high optical appearance [0064] mechanical stability [0065] the largest possible translucent or transparent faces [0066] high flexibility [0067] simple, cost-effective production [0068] impermeability to moisture penetrating into the intervening space between the panes of the door

[0069] Although the present disclosure has been described on the basis of preferred exemplary embodiments, it is not limited thereto, but can be modified in diverse ways.
