FIELD: various technological processes.
SUBSTANCE: group of inventions relates to moulding of hollow containers. Disclosed is a device for moulding hollow containers, a semi-finished product containing a container moulded using the device, a machine for producing the semi-finished product and a method for moulding hollow containers. Device comprises matrix (11) formed by a pair of moulds (12) interacting with each other to create cavity (13) having the shape of obtained container (110), and to form support channel (14) defining additional part (112) of container (110). Device also comprises moulding male die (17) configured to move through support channel (14) to enter cavity (13) and to push and inflate workpiece (F) along walls of cavity (13) to form at least containers (110).
EFFECT: formation of an additional part of the container, which is removed before filling the container, in order to exclude the use of additional closure means.
