Mold system () for manufacturing cardboard-based container, comprising movable mold half () and stationary mold half () located opposite one another. Movable mold half (), movable with respect to stationary mold half (), includes at least a core plate (), a plate-like seal ring () movable with respect to the core, and collar ring (). Stationary mold half () includes at least a mold plate () provided with a mold cavity () and a seal surface (). In the mold system (), an insert () can be supported on and detachably attached to the base () of the mold cavity () reducing the depth H of the mold cavity by its height h. Container () comprises bottom () pressed from cardboard blank and wall () connected to the bottom and plastic rim () connected to the upper edge of the walls.

Mould system for changing the depth of a cardboard-based container

A mould system for manufacturing a container which includes a movable mould half and a stationary mould half which are positioned opposite to each other, wherein the movable mould half includes a core plate provided with a core, a plate-like seal ring that is movable relative to the core, a seal surface which surrounds the core, and a collar ring that is movable relative to the core and the stationary mould half includes a mould plate provided with a mould cavity and a seal surface, wherein in the mould system, a plate-like insert is connected to the seal surface of the seal ring, the insert including a recess which is in contact with a front edge of the seal surface, so that it is in flow communication with molten plastic material flowing from the direction of the collar ring.

Mould system for manufacturing a container

The invention relates to a method of providing board containers (V) with prints and a printing machine that applies the method. According to the invention, the printing machine comprises a turret head (), with uniformly spaced radial arms () diverging from its rotational axis, each arm ending in a mandrel () that carries a container (); and stationary stations () that are located on the path of the turret head for gripping a container, printing it by a printhead (), and removing the printed container (V). At the printing station (), the container () is digital-printed by the printhead (), past which the surface of the container is conveyed by means of a rotational motion. The container can be a conical drinking cup (), which is ink-jet printed by the stationary printhead () by rotating the cup by 360&#xb0; by means of the mandrel () that is pushed inside the cup. The cups () can be produced at a plant in mass-scale production runs and divided into smaller lots, which are delivered to customers and which the customers then print according to their own individual needs.
