A tube holder has a housing having an upwardly opening tube receptacle into which a tube can be inserted. A plurality of clamping elements arranged in the tube receptacle can be brought to abut an outer wall of the tube and a clamping force acting radially on the inserted tube cab be applied by at least one spring element. The clamping elements are pivotably mounted in a pivot bearing about a horizontal axis. Further clamping element are below the first group of pivot elements arranged over the tube receptacle and are under the action of the spring element and/or at least one further spring element. The clamping surface of at least some clamping elements and/or at least some further clamping elements at least in sections has a convex contour, curved about a horizontal axis, in the direction of a longitudinal central axis of the tube receptacle.

A method and system for filling a flexible film bag attached to a face plate with a flowable composition is disclosed. The system includes a chamber for receiving the flexible film bag and a fill tube for dispensing the flowable composition into the flexible film bag, where the fill tube is at least partially disposed in the film bag. The system also includes a first pump in fluid communication with the chamber, where the first pump creates a vacuum between an exterior surface of the flexible film bag and an interior surface of the chamber, such that the flexible film bag expands from an unexpanded state to an expanded state.

Embodiments described herein relate to articles and methods for forming liquid surface films on the interior surfaces of containers for holding one or more products comprising one or more Bingham plastic materials. Bingham plastic materials behave as a solid under no or low shear stress, and behave as viscous liquids when an applied shear stress exceeds a yield stress. In some embodiments, a container for containing a product includes an interior surface and a liquid disposed on the interior surface. Before introduction of a product into a container, the liquid may be surrounded by air. The liquid-air interface in contact with the interior surface makes a contact angle, .sub.os(a), with respect to the interior surface of the container, of about 0. After a product has been introduced to the container, the liquid is at least partially covered by the product. The liquid-product interface in contact with the interior surface, makes a contact angle, .sub.os(p), with respect to the interior surface, of less about 60. The subscript o denotes the liquid, subscript s denotes the interior surface, subscript a denotes air, and subscript p denotes a product. In some embodiments, the contact angle .sub.os(p) can be less than about 50, less than about 40, or less than about 30.
