Abstract

An active material container for a functional housing has an air-permeable casing with an interior and an active material arranged inside the interior. One or more rim-side guide elements are arranged at the air-permeable casing and are provided to linearly slidably guide the active material container in an insertion direction in corresponding guide elements of a receptacle of the functional housing. The functional housing is preferably a battery housing.

First claim

What is claimed is:

1. An active material container for a functional housing, the active material container comprising:
a casing being air-permeable and comprising an interior;
an active material arranged inside the interior; and
a guide rail arranged at the casing and configured to linearly slidably guide the active material container in an insertion direction in a guide slot of a receptacle of the functional housing, the guide rail comprising a locking tongue arranged at a central segment of the guide rail.

2. The active material container according to claim 1 , wherein the guide rail extends in the insertion direction.

3. The active material container according to claim 1 , wherein the casing comprises walls that are facing away from each other, and
the guide rail is arranged at each of the walls.

4. The active material container according to claim 1 , wherein the casing comprises at least one lattice-shaped wall section or a lattice-shaped wall.

5. The active material container according to claim 4 , wherein the at least one lattice-shaped wall section or the lattice-shaped wall comprises an average lattice mesh width of more than 0.5 mm.

6. The active material container according to claim 4 , wherein the casing is a lattice housing.

7. The active material container according to claim 4 , wherein the at least one lattice-shaped wall section or the lattice-shaped wall comprises lattice stays comprising a thickness of at least 0.8 mm.

8. The active material container according to claim 1 , wherein the guide rail extends away in a radial direction from a wall of the casing.

9. The active material container according to claim 1 , wherein the casing is embodied in a basket shape and further comprises an insertion opening configured to enable an exchange of the active material in the interior of the casing, the exchange of the active material being in the insertion direction, and
the active material container comprises a cover configured to close the insertion opening.

10. The active material container according to claim 1 , wherein the guide rail is embodied in an arc shape, and
the central segment of the guide rail extends parallel to the insertion direction.

11. The active material container according to claim 1 , wherein the locking tongue comprises:
a first springy end comprising a locking nose; and
a second end connected to the central segment of the guide rail.

12. The active material container according to claim 1 , further comprising a fiber receptacle arranged in the casing, the fiber receptacle comprising at least one first material layer of nonwoven material and at least one second material layer of nonwoven material,
between the at least one first material layer and the at least one second material layer, a cavity is formed, the cavity being at least partially filled with the active material, and
the fiber receptacle further comprises an air-permeable filter region and an at least partially reinforced rim region comprising a reinforced partial region, the reinforced partial region comprising a reduced air permeability in comparison to the air-permeable filter region.

13. The active material container according to claim 1 , wherein the active material comprises or is comprised of at least one drying agent and/or an adsorbent agent for harmful gases.

14. The active material container according to claim 1 , wherein the active material comprises any one or any combination of active carbon, zeolite, and an adsorbent agent for CO, CO 2 , NOx and/or hydrocarbons.

15. A battery housing comprising:
a receptacle comprising a guide slot; and
an active material container comprising:
a casing being air-permeable and comprising an interior;
an active material arranged inside the interior; and
a guide rail arranged at the casing and configured to linearly slidably guide the active material container in an insertion direction in the guide slot of the receptacle, the guide rail comprising a locking tongue arranged at a central segment of the guide rail.

16. The battery housing according to claim 15 , wherein the guide rail and the guide slot interact to achieve a linear slidable guiding action of the active material container in the receptacle.

17. The battery housing according to claim 16 , wherein the guide rail and the guide slot comprise an interface, comprising a locking cutout and a locking nose interacting with the locking cutout to limit a mutual linear slidability of the guide rail and the guide slot.
