The metal cap is new cheaper and bad design.  Be careful.
The cap is cheap tin metal.  It spins in place.  I have to find a knife to separate top and bottom metal pieces on the cap.  If I close it does not seal properly.  If you try to screw it tight then the cap pulls out the plastic pour spout from the bottle.  Then you have a project in your hands to press in the spout.  Your hands get the messy fish oil smell.  Then good luck.  I don't know why in the world Carlson went to this design.<br />The original bottle design had a nice sturdy plastic cap which seals well.  There are some sellers on Amazon who still show the original bottle's photo but send you the bottle with the cheap metal cap.  VERY BAD DESIGN.
