Abstract
A plastic material container, e.g. a beverage bottle, having a neck which requires the use of a smaller amount of plastic than the bottle necks of the prior art, and which is able to ensure a complete functionality for coupling the cap, ensuring at the same time the possibility of implementing the traditional supporting; sealing and handling operations of the bottle carried out during the various steps of manufacturing the same.
Claims16
A plastic material container comprising:
- a neck comprising a cylindrical tubular segment, defining a longitudinal axis,
- a threaded end portion for screwing a cap of said container thereon, said threaded end portion comprising a thread and a threaded base surface,
- a single annular protrusion serving both a container cap seal tearing function and a conveying support flange function, and
- an annular groove arranged between said threaded end portion and said annular protrusion, for a grip of the container by appropriate gripping members,
- wherein said annular groove is present on the threaded base surface and forms a recess with respect to the threaded base surface such that a bottom surface, closest to said longitudinal axis, of said annular groove is closer to the longitudinal axis than the threaded base surface is to the longitudinal axis.
