Abstract
A liquid container for a motor vehicle, having a first half-shell and a second half-shell, the half-shells delimiting a storage volume for accommodating liquid, the first half-shell having a first support layer and a first barrier layer, the second half-shell having a second support layer and a second barrier layer, the first barrier being situated on a side of the first support layer facing the storage volume, and the second barrier layer being situated on a side of the second support layer facing the storage volume.
Claims12
A liquid container for a motor vehicle comprising:
- a first half-shell;
- and
- a second half-shell;
- wherein the half-shells delimit a storage volume for accommodating liquid;
- wherein the first half-shell has a first support layer and a first barrier layer;
- wherein the second half-shell has a second support layer and a second barrier layer;
- wherein the first barrier layer is situated on a side of the first support layer facing the storage volume;
- wherein the second barrier layer is situated on a side of the second support layer facing the storage volume;
- wherein the half-shells in a connecting area are directly integrally joined together, the first barrier layer in the connecting area being directly integrally joined to the second barrier layer;
- wherein the first support layer and the second support layer in the connecting area are spaced apart from one another, with no contact between the first support layer and the second support layer, and the support layers bordering the barrier layers on both sides;
- and
- wherein a plastic that is used for attaching molded elements, connecting parts, or functional units is locally molded onto a side of at least one of the barrier layers facing the storage volume.
A liquid container for a motor vehicle comprising:
- a first half-shell;
- and
- a second half-shell;
- wherein the half-shells delimit a storage volume for accommodating liquid;
- wherein the first half-shell has a first support layer and a first barrier layer;
- wherein the second half-shell has a second support layer and a second barrier layer;
- wherein the first barrier layer is situated on a side of the first support layer facing the storage volume;
- wherein the second barrier layer is situated on a side of the second support layer facing the storage volume;
- wherein the half-shells in a connecting area are integrally joined together, the first support layer in the connecting area being integrally joined to the second support layer;
- wherein the first barrier layer and the second barrier layer in the connecting area are spaced apart from one another, with no contact between the first barrier layer and the second barrier layer;
- wherein solidified melt of a material of the first support layer and/or of a material of the second support layer is situated between the barrier layers;
- wherein a permeation path is formed in the connecting area between the spaced-apart barrier layers;
- wherein a length of the permeation path, viewed in a cross section, is greater than or equal to twice the width of the permeation path;
- and
- wherein the width of the permeation path corresponds to the distance between the barrier layers in the connecting area.
