How to match between two special characters

Question

I have a string of form:

product_type_l1==costumes&+product_type_l2==1950s&+product_type_l3==adult&+product_type_l4==no
filter&+product_type_l5==female&+id=fun2502bl-m

I'd like to match things between == and & as well as the very last one before the = .

So in this case it would be:

costumes 1950s adult nofilter femalefun2502b1-m

Tried for one hour and I can't figure it out!
