Abstract
Methods of manufacturing and fixtures for manufacturing containers, particularly for holding cosmetic products, using thin-walled tubes. One end of a container may be formed using an integral process, such as insert molding, while the other end of the container is formed using assembly steps, such as welding, to form a completed cosmetics container from a thin-walled tube.
Claims12
A method of manufacturing a container using a thin-walled tube having a first open end and a second open end for said container, the method comprising:
- extruding the thin-walled tube with one or more layers;
- attaching a first structure on the first open end of the thin-walled tube, the first structure including a receiving portion for receiving a cap, and an aperture for dispensing a product, the aperture having an inner diameter smaller than an inner diameter of the thin-walled tube;
- after attaching the first structure, inserting an end of a mandrel from outside the thin-walled tube through the aperture and into an interior of the thin-walled tube;
- placing an end cap piece against the end of the mandrel such that at least a portion of the end cap piece is surrounded by the thin-walled tube;
- resting the receiving portion on the mandrel;
- and
- securing the second open end of the thin-walled tube to the end cap piece by placing a weld fixture over an outer surface of both the end cap and the second open end of the thin-walled tube, and applying energy to a junction between the thin-walled tube and the end cap piece.

- wherein the end cap piece has a slot configured for securely receiving the mandrel therein.
