The bottles the hotels are using have a very thick plastic spout (to support all of the re-use).
Because this is actual kind of fun, I got my hands on an almost empty bottle which does not have a flimsy pump as you describe it. Emptied the last bits, rinsed and dried it.
So a good solid pump function on a 350mL bottle of soap.
As the company here does not have to achieve the same quality look and feel to the bottle as the House of Dior, and because material costs probably is a a bigger concern in their profit margin, it is actually lighter than the Dior one. So the plastic saving is bigger in this example
91g/350mL= 0.26g/mL a 32%. saving compared to the 40mL bottle.
I must be a glutton for punishment, but I actually look forward to seeing the arguments against this example.
