A method and a system are disclosed for detecting the features of a water layer in layered enclosures of single unit dose products. Thanks to the method and the system of the invention, the layered enclosures may be manufactured to higher specifications and quality owing to real time control of the features of the water layer between the enclosure layers. The technical advantage of the method of the invention consists in the possibility to detect the features after formation of the layered enclosure is complete—hence inspecting the finished product—and to feed back the detected information to the very water laying device for a real time adjustment of the features of the water layer at the areas where acceptance criteria are not met.

Methods and manufactures disclosed herein generally relate to a cannular composite (ITC) structure composed of multiple layers of sealing, reinforcement, sensing, protection, and interspatial injected materials.

A method and system for determining an integrity of a container, including obtaining a pressure inside a container by producing, filling and/or sealing a container using heat or at cold conditions. Transmitting a light signal through a headspace of the container and determining, based on the transmitted light signal being detected, the integrity of the container.

A leak detection system for detecting breaches in sealed food containers is disclosed. The leak detection system comprises a first optical sensor configured to transmit a light signal across a first testing path, said first optical sensor being sensitive to gas composition variations. A permeable pressing member is configured to, in use, apply pressure to the sealed food container. The first optical sensor is arranged such that at least a portion of the first testing path along which the light signal is transmitted is located behind or within the permeable pressing member.

A method for inspecting a seal of a flexible container for a fluid, particularly a fluid medication, includes covering the container at least in part—preferably completely—by a gas-permeable layer. The container, together with the gas-permeable layer, is arranged in a flexible, substantially gas-tight bag, and the substantially gas-tight bag is evacuated by pumping out via a bag opening. The container is filled with a noble gas, and the presence of noble gas, which escapes out of the bag opening from the container via a leak through the gas-permeable layer, is detected.

Disclosed is a method of integrity testing of a single-use system for processing a fluidic material. In the inventive method, a single-use system for processing at least one fluidic material is provided. The single-use system has at least one plastic component. A test gas is applied to a lumen of the single-use system. The test gas has one or more of spectral absorption or spectral emission properties in the infrared spectral range distinguishable from ambient air. At least a part of the single-use system is monitored using an infrared camera. A method of processing a fluidic material by using a single-use system and a test system for integrity testing of a single-use system are also disclosed.

There is provided a gas sensor fault detection device that detects a sensor fault in a gas leak inspection device. The gas sensor fault detection device includes: a gas blowing unit that blows a gas toward a detection area of a gas sensor of the gas leak inspection device; and a position fixing unit that fixes a position of the gas blowing unit with reference to a hypothetical gas leak position of an inspection target being inspected by the gas leak inspection device.

A method for detecting leakages of fluids from sealed containers includes defining a detection zone in which a sealed container will be placed, putting the detection zone in communication with at least one gas sensor through at least one duct, introducing a flushing gas into the detection zone through the at least one duct, placing a container in the detection zone, sucking gases from the detection zone through the duct and transferring them to the sensor for ascertaining the presence of a gas leakage in the container.

Integrity of a flexible bag is verified by a testing system, using helium to detect existence of a possible hole. The flexible bag is preliminary placed in vacuum chamber of a fluid-tightly isolated enclosure. After connecting a port of the bag to a helium feeding pipe, vacuum suction is performed to obtain vacuum outside the bag in the enclosure. Then, a first amount of helium is diffused in the internal volume of the enclosure through a gas permeable wall, to increase helium partial pressure outside the flexible bag. After, in a test phase while said vacuum suction is still performed, the bag is filled with a second amount of helium. A detector detects information representative of helium partial pressure in the internal volume, to allow detection of helium escaping from the bag, by analysis of a helium partial pressure drop.

A method, a device and a use of the device are provided for carrying out an integrity test on a test container (1) that has at least one flexible casing material. The method includes the steps of: filling a test fluid into the test container (1); and detecting the presence of test fluid directly outside the test container (1). The test fluid is designed in such a way that the permeation rate of test fluid through undamaged casing material of the test container (1) is not greater than 1.Math.10.sup.−6 mbar.Math.m/(s.Math.bar).
