ABSTRACT:
A contractible plastic bellows container is disclosed, which can be made in a single molding process and is capable of discharging practically all the viscous fluid content. A plastic bellows container of the invention comprises a neck portion with an opening, a top shoulder section, a bottom shoulder section, and a bottom protrusion. The bottom shoulder section and the bottom protrusion are reversible. When the plastic bellows container is fully contracted, the space created therein by the overlapping bellows can be substantially eliminated by the reversed bottom protrusion entering inside of the neck portion and the reversed bottom shoulder section. The bellows container may advantageously be used with an airtight discharging means.
