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:
an air-permeable casing comprising an interior; an active material arranged inside the interior; one or more rim-side guide means arranged at the air-permeable casing and configured to linearly slidably guide the active material container in an insertion direction in corresponding guide means of a receptacle of the functional housing.

2 . The active material container according to claim 1 , wherein the one or more rim-side guide means extend 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 wherein the rim-side guide means are arranged at the walls that are facing away from each other.

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 and the lattice stays have a thickness of at least 0.8 mm.

8 . The active material container according to claim 1 , wherein the one or more rim-side guide means are embodied as a guide rail, respectively, 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 comprises an insertion opening configured to enable an exchange of the active material in the interior of the casing, wherein the exchange of the active material is realized in the insertion direction, wherein the active material container comprises a cover configured to close the insertion opening.

10 . The active material container according to claim 1 , wherein the one or more rim-side guide means are embodied as a guide rail, respectively, and wherein the guide rail comprises a locking means.

11 . The active material container according to claim 10 , wherein the locking means is at least one locking tongue.

12 . The active material container according to claim 10 , wherein the guide rail is embodied in an arc shape and comprises a central segment extending parallel to the insertion direction.

13 . The active material container according to claim 12 , wherein the guide rail comprises a locking tongue arranged at the central segment.

14 . The active material container according to claim 13 , wherein the locking tongue comprises a first springy end comprising at least one locking means and further comprises a second end connected to the central segment.

15 . The active material container according to claim 14 , wherein the at least one locking means is a locking nose.

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

17 . 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.

18 . The active material container according to claim 1 , wherein the active material is selected from the group consisting of active carbon; zeolite; an adsorbent agent for CO, CO 2 , NO X and/or hydrocarbons; and combinations thereof.

19 . A battery housing comprising:
a receptacle comprising edge-side guide means; an active material container comprising: an air-permeable casing comprising an interior; an active material arranged inside the interior; and one or more rim-side guide means arranged at the air-permeable casing and configured to linearly slidably guide the active material container in an insertion direction in the edge-side guide means of the receptacle.

20 . The battery housing according to claim 19 , wherein the edge-side guide means are guide slots and wherein the rim-side guide means are guide rails, wherein the guide rails and the guide slots interact to achieve a linear slidable guiding action of the active material container in the receptacle.

21 . The battery housing according to claim 20 , wherein the guide rails and the guide slots 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 rails and the guide slots.

22 . A method for mounting an active material container in a battery housing, the method comprising:
moving the active material container in a linear sliding action into an end position in a receptacle of the battery housing by inserting one or more rim-side guide means arranged at an air-permeable casing of the active material container into corresponding edge-side guide means of the receptacle of the battery housing; and locking the active material container in the end position in the receptacle.
