The choice of the word "funktionen" is slightly odd here for something that is supposed to be covered by both patent protection and design protection - mönsterskyddad is definitely "design-protected" [•Designskydd och mönsterskydd är olika ord för samma sak http://www.prv.se/sv/Kunskapscenter/Immaterialratt/Om-design... - in view of the fact that patents generally protect functional or technical features, whereas designs protect non-functional or ornamental features. I would therefore suggest using the word "features" rather than "function".

The above PRV site has a useful explanation of how the different types of protection work:
Varumärke och andra skydd
Här kan du se hur en cykelhjälm kan skyddas med hjälp av varumärkesskydd, patent och designskydd:
Det du inte vill att någon ska härma - Exempel - Skyddsform
Hjälmens namn - Speedy - Varumärkesskydd
Hur du löst problemet med att hjälmen ska ha perfekt passform av säkerhetsskäl - Remmarna är fästa på ett mycket speciellt sätt - Patent
Hjälmens snygga, tuffa utseende - Fartränder - Designskydd

Trademarks and other protection
Here you can see how a bicycle helmet can be protected with the help of trademark, patent and design protection:
What you do not want anyone to imitate - Example - Form of protection
The helmet's name - Speedy - Trademark
How you solved the problem of the helmet fitting perfectly for safety reasons - The straps are attached in a very special way - Patent
The helmet's attractive, cool look - Speed stripes - Design

English-language example of a trademarked product also enjoying patent and design protection:
Core 150™
A globally unique patent and design protected product.

See also, for example:
This principle was based on the interrelationship between patent, design and trade mark laws, functional and attractive shapes being protected by patents and designs respectively and not by a registered trade mark.
