  • Patent number: 6234360
    Abstract: A dispenser of paste material, such as toothpaste, having an outer housing with an open upper side and a dome at the lower side, the roof of which dome includes the closing body of an air entry valve, which air entry valve displaces into the open position when there is a negative pressure within the outer housing, the dispenser also having an inner housing that protrudes upwardly from the outer housing and which includes an application surface and a nozzle opening on its headpiece, wherein the inner housing can be pushed, using the application surface, against the spring force of a bellows that is disposed in the outer housing, itself being sealed off from the inner housing, the result being that, when this force application of force takes place, a transport slug, which travels within the inner housing in the direction of the nozzle opening, pushes material ahead of itself in response to air pressure that has accumulated behind it.
