Historically, the first caps were made with a friction closure (those that are generically defined slip caps), with the cap that fits on the body. There are different variants of this type of choice, depending on the way in which the joint is made; the two main classes are the so-called cone cap (conical section cap) in which the interlocking surface is a truncated cone, and the so-called straight cap (cylindrical section cap) in which the interlocking surface is cylindrical, among the latter there are then the so-called tapered cap (conical or tapered cap) in vogue at the end of the 19th century.
