A flexible lid seal detector incorporates a compression body having a cavity including a sensor. The detector has a distal end comprising a plurality of concentric compression rings surrounding the cavity. An outer-most ring is defined by outer and inner shaping rims. The distal end includes a recessed lid deflection volume defined by the inner rim and a distal surface of the compression body. The deflection volume may receive a portion of a flexible lid when at least one of the rings applies a compressive force thereto, thereby deforming the lid into the deflection volume. The deflection volume may include a second compression ring and its respective inner and outer shaping rims. A seal detector system may include the detector with a controller configured to receive data from the sensor for a predetermined period of time while the detector applies the compressive force to the lid.

A method is provided for detecting leaks in a disposable medical fluid cassette that includes a base and a flexible membrane attached to the base in such a way that the base and the flexible membrane cooperate to at least partially form a fluid passageway. The method includes applying a first force to the flexible membrane, measuring a first physical property of a system that includes the medical fluid cassette a medical fluid pumping machine, removing the first force from the flexible membrane, applying a second force to the flexible membrane, measuring a second physical property of the system, and determining whether the medical fluid cassette leaks based on a comparison of the first physical property and the second physical property.

The invention relates to a simplified method for detecting leaks on a non-rigid test specimen, comprising the steps of: introducing the test specimen into a film chamber, lowering the pressure in the film chamber outside of said test specimen, and detecting a leak in the test specimen on the basis of a spatial change in the film of said film chamber.

A production method and system performing the production method, the method includes detecting integrity of a hermetic seal of a container that is being transported by a conveyor, the container including an elastically deformable cup containing a product and a fluid, and having an open mouth and a deformable lid attached around the open mouth of the cup, the detecting including squeezing the cup to pressurize the fluid contained in the container; and determining with a detector whether the squeezing caused the lid to deform; and when it is determined that the squeezing failed to deform the lid, removing the container from the conveyor.

A device and a method for detecting leaks of closed containers with an inspection apparatus configured to determine the curvature of the container closure of the closed containers, as well as an evaluation apparatus by means of which the curvature of the closure is compared with a predefined value. A pressure generating apparatus is used to press each container closure flat prior to inspection. The pressure-generating apparatus comprises an actuator with which pressure is applied locally to each container closure from the outside.

A form-fill-seal machine forms a bag by filling and sealing a packing object in a wrapping material. The form-fill-seal machine includes a thickness adjustment unit which adjusts a thickness of the bag and a control unit which controls an operation of the thickness adjustment unit. The control unit acquires thickness information obtained in a rear stage of the form-fill-seal machine and relating to a thickness of the bag and controls the operation of the thickness adjustment unit on the basis of a result obtained by performing statistical processing on the thickness information.
