Abstract
Bag (1) for application in an external container (2) for forming a pressure vessel (2) with two separate compartments (3,4), that is manufactured from an elastic and stretchable material that is such that the bag (1) can stretch from an unstretched state to a stretched state when the bag (1) is filled with a product (9) or when the bag (1) is inflated with air, whereby the stretching of the bag (1) is reversible and whereby the stretch is so substantial that the bag (1) can be used for constructing pressure vessels (2) of diverse dimensions.
Claims25
Bag for application in an external container for forming a pressure vessel with two separate compartments, whereby the external container forms a first compartment and the bag is intended to be placed in the first compartment as an internal bag to form a second compartment, whereby the bag is also intended to be filled with a product, wherein the bag is manufactured from an elastic and stretchable material that is such that the bag can be expanded from an empty state to a maximum expanded unstretched state, and that the bag can stretch from an unstretched state to a stretched state when the bag is filled with the product or when the bag is inflated with air or another gas, whereby the stretching of the bag is reversible and whereby the stretch is so substantial that the bag can be used for constructing pressure vessels of diverse dimensions.
(canceled)
Series of pressure vessels of diverse dimensions of the type with two compartments whereby a first compartment is formed by an external container, in which an internal bag is provided for forming a second compartment, whereby the bag is filled with a product or intended to be filled with a product, whereby the pressure vessel is also provided with a valve for the supply of product to and the removal of product from the bag and whereby, both the external container, and the internal bag are connected to the valve by means of a gastight connection, whereby the bag can be expanded from an empty state to a maximum expanded state, wherein the bag is manufactured from an elastic and stretchable material, that is such that the bag can stretch from the maximum expanded state to a stretched state when the bag is filled with the product or when the bag is inflated with air or another gas, whereby the stretching of the bag is reversible and whereby each pressure vessel, irrespective of its dimensions, is provided with the same type of bag, whereby all aforementioned bags have the same properties and more specifically in the maximum expanded unstretched state have the same size and wall thickness.
Method for manufacturing a series of pressure vessels of diverse dimensions, whereby each pressure vessel is of a type with two compartments, whereby a first compartment is formed by an external container, in which an internal bag is provided for forming a second compartment, whereby the bag is filled with a product, whereby the pressure vessel is also provided with a valve for the supply of product to and the removal of product from the bag and whereby both the external container and the internal bag are connected to the valve by means of a gastight connection, wherein the bag is manufactured from an elastic and stretchable material, that is such that the bag can be expanded from an empty state to a maximum expanded unstretched state and that the bag can stretch from an unstretched state to a stretched state when the bag is filled with the product or when the bag is inflated with air or another gas, whereby the stretching of the bag is reversible and whereby, for pressure vessels of diverse dimensions, bags of the same type are used that each have the same dimensions and properties, and which, more specifically, have a certain fixed size and wall thickness in the unstretched state, irrespective of the dimensions of the pressure vessel.
