Abstract
The present invention relates to a tub configured to receive a volume of liquid for a humidifier, comprising at least one plastic component and at least one metal component, which together form a space for receiving said volume of liquid, wherein the at least one metal component and the at least one plastic component are attached to each other by means of a silicone seal. Furthermore, the invention relates to method for manufacturing a tub for a humidifier.
Claims31
A tub configured to receive a volume of liquid for a humidifier, comprising:
- at least one plastic component having a bottom wall with a through hole;
- and
- at least one metal component;
- wherein the at least one metal component and the at least one plastic component are attached to each other in a fluid tight manner by a silicone seal, such that the at least one metal component and the at least one plastic component together form a space for receiving said volume of liquid,
- wherein only an upper surface of the at least one metal component is treated with a silicone adhesion promoting agent,
- wherein the silicone seal is attached to only the upper surface of the at least one metal component thereby leaving a lower surface of the at least one metal component exposed,
- wherein the through hole is closed by said at least one metal component and said silicone seal, and
- wherein the silicone seal covers at least a portion of the at least one metal component, wherein the portion of the at least one metal component is not overlapping with the plastic component;
- and/or the silicone seal covers at least a portion of the at least one plastic component, wherein the portion of the plastic component is not overlapping with the at least one metal component.
