Good find on the sitpad.
Yup, those are real words. Usually in some way related to the product, sometimes in a double meaning or tongue in cheek sort of way. Upptäcka means discover, very straight forward name for a series of travel gear.
Pruta is the name of one of their Tupperware sets, and means to haggle or bargain, implying of course that you would be cheap to keep your dinner left overs.
Jämka, meaning to reconcile, is the name of their other set of plastic food storage containers.
Smaska, meaning somewhere between a munch and a slurp, is the name of their sippy cups and other kids eating utensils.
When it is not a real word it is a place name, like the Karlstad couch, or a proper name such as the Ivar shelf, not nearly as much fun in my opinion.
