Abstract: A self-standing type bag-shaped vacuum container has a self-standing container including a wall formed of a soft sheet, a pouring port, and a check valve mounted in the pouring port. The check valve is opened to allow the migration of a content of the container when subjected to a pressure in the pouring direction, but is closed when subjected to a pressure in a filling direction, so that the inside of the container is evacuated. The self-standing container can be optimized for storing beverages or the like which are negatively effected by contact with air, because the content will be oxidized with the air. The vacuum type container will not lose its self-standing property even if the content is reduced, and can stand stably by itself.

Abstract: A plastic container having a storage chamber which graduates from a shoulder section into a bottle neck, in such a way that the length of the bottle neck can be changed about its axis. Thus, this invention provides a constriction between the shoulder section and a pour-out area.

Liquid, free-flowing and pourable media can be discharged in doses using a metering element which is fixed to the top of the bottle neck and which penetrates the constriction. By exerting pressure on the metering element, it is possible to establish an open or closed connection between the metering element and the storage chamber of the plastic container.

The first piston is fixed to a closure member capable, selectively, of closing off/exposing at least one outlet of the dosing cavity. During a first phase of the movement of the dosing cavity, the first piston is driven by through the effect of the pressure of the product being exerted on the second piston and, during a second phase of the movement of the dosing cavity, the first piston is driven by the pressure of the product being exerted on the first piston, the second piston being immobilized in translation during this second phase.

Abstract: A dispenser can automatically dispense chemical from an aerosol container at predetermined intervals without the use of electric power. A diaphragm at least partially defines an accumulation chamber that receives chemical from the can during an accumulation phase. Once the internal pressure of the accumulation chamber reaches a predetermined threshold, the diaphragm moves, carrying with it valving that controls a spray burst. The diaphragm assumes its original position when the pressure within the accumulation chamber falls below a threshold pressure. A barrier prevents the aerosol container from resupplying the accumulation chamber at a high rate during the spray phase, preferably due to a porous gasket disposed in a passageway linking the dispenser to the aerosol container.
