I like the way this 1955 Life Magazine ad for “Mennen shampoo for men” (on left) touts the modernity of its bottle design.
Finally! A modern shampoo for modern man. In a slip-proof, unbreakable bottle.
The patent drawing on the right is a “combination shampoo bottle and massager.” Clearly, these two bottles were related, but I wasn’t sure how. The patent, by Charles M. Zampetti, was obtained three years after the ad, in 1958. So the design patent didn’t appear to cover the Mennen Shampoo bottle’s design. And the patent was not assigned to Mennen…
(Patent-puzzle solved, after the fold…)
Then I noticed Zampelli’s patent had an “other references” section which cited the Mennen shampoo bottle on page 296 of the 1956 edition of “Modern Packaging Encyclopedia.”
