The symbol on the package of your original post is also known as a fleur-de-lis; one of the most recognized forms of which is used in the Boy Scouts logo (below). Here is some other information on it from en.wikipedia.com:
The fleur-de-lis or fleur-de-lys (plural: fleurs-de-lis) is a stylized lily (in French, fleur means flower, and lis means lily) or iris that is used as a decorative design or symbol. It may be "at one and the same time, religious, political, dynastic, artistic, emblematic, and symbolic", especially in French heraldry.
While the fleur-de-lis has appeared on countless European coats of arms and flags over the centuries, it is particularly associated with the French monarchy in a historical context, and continues to appear in the arms of the King of Spain and the Grand Duke of Luxembourg and members of the House of Bourbon. It remains an enduring symbol of France that appears on French postage stamps, although it has never been adopted officially by any of the French republics. According to French historian Georges Duby, the three petals represent the medieval social classes: those who worked, those who fought, and those who prayed.
Electrolux seemed to have used this symbol on packaging and labeling in the 1960s with the cursive wordmark of the 1950s. The 1962 serifed capitals logo with the "boat-shaped" border eventually replaced it.
