A toothpaste rolling assembly for squeezing toothpaste from a tube of toothpaste includes a key that has a slot extending therethrough to receive an end of a toothpaste tube thereby facilitating the toothpaste tube to be wrapped around the key. A gear is positionable around the key and a sleeve is slidable over the key. The sleeve has a slot therein to accommodate the toothpaste tube when the sleeve is slid over the key. The sleeve has a pair of lobes thereon and each of the lobes releasably engages the gear for retaining the sleeve at various points of rotation about the key. In this way the sleeve can be continually rotated on the key for squeezing toothpaste out of the toothpaste tube.

A multi-chamber bag portion can be used as a package for a curable multi-component compound. The multi-chamber bag portion has at least two chambers separated from one another in liquid-tight manner, where one of the chambers is filled with a reactive component and at least one other chamber with a hardener component for the reactive component. The multi-chamber bag portion also has at least one separating element, which in storage condition separates the chambers from one another in liquid-tight manner and in ready-to-use condition provides fluidic communication between the chambers for mixing of the reactive component and the hardener component. An opening portion, which can be opened to discharge the mixed multi-component compound, is also a component of the multi-chamber bag portion.

A collapsible tube squeezing device includes a tubular member and a rotary member. A tubular wall of the tubular member has a slit which extends in an axial direction through two opened ends. The rotary member has a tubular shaft rotatably disposed in the tubular wall about an axis, a handle connected to a shaft end for a manual rotational operation, and a centered member connected to an opposite shaft end, and configured to be kept and centered along the axis. A shaft wall of the tubular shaft is coaxial with and spaced apart from the tubular wall, and has a slot for a sealed end of a collapsible tube to be inserted thereinto.

A device for discharging contents from a squeezable tube defining a bottom edge and a top nozzle for discharge of the contents comprises a main longitudinal body comprising a slot for slidingly receiving the bottom edge of the tube therein. A turning handle is mounted to the main longitudinal body for providing a user to impart a turning movement to the main longitudinal body and the bottom edge about the longitudinal axis to roll the tube about the main longitudinal body thereby squeezing the tube and causing the contents therein to be discharged therefrom. The turning handle and the main longitudinal body define at least one opening for receiving at least a portion of the tube rolled about the main longitudinal body therein. The main longitudinal body is slidable along a length of the bottom edge thereby providing the user to selectively move the turning handle towards the rolled tube so as to receive a portion thereof within the at least one opening preventing the rolled tube from unrolling or away from the rolled tube so as to remove the portion thereof from the at least one opening.
