Looking a bit further the first Patent seems to be this one. 1954.

Hello Nikolai,
I don't have any reading or teaching references for you, but here's a
product which I show all my students every year.
Can't show photos on the list so here's a link to the Patent
http://www.google.co.uk/url?sa=t&rct=j&q=folding%20disposable%20rasor&source=web&cd=3&ved=0CEoQFjAC&url=http%3A%2F%2Fwww.patentstorm.us%2Fpatents%2F6571476%2Fdescription.html&ei=d_oGT8LNGdDI8gPe8bHFAQ&usg=AFQjCNFkoyADH4FTc8s408Aani3iWPL76Q&sig2=5r2r8FI8UfJwScqEfEct3A&cad=rja
It's a rasor. Given as part of the travel kit on a flight many years ago. It
is made from injection moulded polypropylene, and has both living hinges and
moulded in poppers that clip it in the open and closed positions.
As you open it and bring the edges of the handle togther, the fold angles
make the head tilt down to the correct angle.
The blade or blades (there are both one and two bade versions) are held
between two layers of the moulding by pegs that have been "rivetted" over by
heat of ultrasonic vibration.
It has some writing in the moulding saying designed in Italy and maybe the
patent number. I'll let you have the details when I'm back in my office next
week if you like.
For me, this is a truly inspirational product. You can almost hear the
thought process of the combination of origami and the poppers linked to the
familiar book of matches.
Kind regards, and good luck with your project.
