An injection mold for molding a flip-top closure having a body portion and a lid attached to the body portion by a living hinge has first and second mold portions for defining first and second portions of the flip-top closure respectively, a lid closing tool for closing the lid of the flip-top closure on the body portion after a molding of the flip-top closure in the injection mold and before an ejection of the flip-top closure from the injection mold, and first and second linear actuators operatively connected to the lid closing tool for moving the lid closing tool about first and second axes respectively. The first and second linear actuators are controllable to move the lid closing tool along a lid closing path for closing the lid. An in-mold lid closing device and a method for making a flip-top closure are also disclosed.

Injection mold having an in-mold lid closing device

The invention relates to a container and to the use thereof. The container has a chamber with a base for receiving a mixture component and an adapter for fixing the chamber to a second container. The adapter is connected to the chamber via a first connector and has a second connector to connect to the second container. Additionally, the adapter forms a flow channel for the mixture component extending between the first and the second connector. The adapter also has a blade element in the flow channel comprising a blade facing the base of the chamber in order to open the base. The first connector allows the chamber to rotate relative to the adapter and to the blade, said blade designed to cut through the base of the chamber along the edge of the base while the chamber rotates.

Container and method for adding a mixture component

An injection-molding device for producing at least one tube head having a tube shoulder and a neck formed thereon has a press-out opening comprising a mold that defines a mold cavity and a nozzle that interacts with the mold. The nozzle has a valve needle that can be moved in the nozzle body. The valve needle is surrounded by a first flow channel, through which a first material component can be pressed out. The opening of the nozzle is closed by the valve needle head in a retracted position of the valve needle and released by the valve needle head in an advanced position of the valve needle In the advanced position of the valve needle, an annular outlet opening is formed, which establishes a fluid connection into the mold cavity together with an annular gap of the mold serving as a gate.
