I don't know if it was a mistake or what... But I did not get the erlenmeyer pictured above!
Those oranges are the standard ones i remember using in my lab tech days.  The one I got had a blue lid which I JUST discovered has a second unscrewable cap, and a gas filter built in!  Cap can screw back on to seal.  Thanks!
