A method for testing tightness of container includes placing a bell-shaped test head over a mouth of the container, sealing the container against the test head, accommodating at least a portion of the container in a testing chamber within the test head, increasing a pressure difference between a pressure within the testing chamber and an internal pressure of the container, identifying evidence of matter exiting the container and entering the testing chamber. Typical evidence includes emergence of filling substance into the testing chamber and/or foaming of the filling substance in the testing chamber. Identifying such evidence includes using a camera to monitor either the region of the container or the test chamber for the evidence.

A leak detecting device for a fluid filled vessel including a housing having a continuous perimeter edge sized to extend around an underwater surface, the housing forming a hollow interior, an anchoring attachment extending through an aperture in the housing for immovably anchoring the housing to the underwater surface, a resilient member secured to the perimeter edge of the housing and adapted to contact and form a seal between the housing and the underwater surface, and an inlet forming an opening through an entirety of a wall of the housing accessible from an exterior of the housing.

A method and apparatus for measuring gas leakage in a graduated cylinder where water is displaced by the gas in a graduated cylinder in combination with a balance scale, allowing for both a visual indication of the gas detected and a change in weight measurement on the scale, correlating to a certain volume of gas detected.

A leak detecting device for water filled vessel such as a swimming pool. An annular resilient seal having a central opening contacts the surface of the vessel under water and creates a seal between the resilient seal and the vessel. A rigid housing open in its interior is coupled to the resilient seal and has an opening for an inlet to deliver fluid into the interior of the housing, or couple a flow meter thereto to measure the fluid flow, or deliver a dye into the housing and through the central opening of the resilient seal.

A method for detecting leaks within an underwater surface of a water filled swimming pool including the steps of: (1) providing a component defining a hollow interior, having an annular outer periphery and a central opening adapted to encircle the underwater surface and seal there against; (2) providing a fluid inlet leading into the interior of the component at an off-centered location on the component; (3) placing the annular outer periphery around the outer periphery of the underwater surface within the water filled swimming pool, sealing the component against the underwater surface; (4) maintaining the annular resilient member in a stationary position relative to the underwater surface; and (5) permitting depositing a dye solution into the water filled swimming pool proximate the fluid inlet.

Apparatus and associated methods relate to a weight reduced ferrule (WRF) pharmaceutical container closure system that consumes less resources while having sufficient tensile strength to sealingly couple a closure to a canister. The pharmaceutical canister may, for example, include a lip extending into a cavity of the container from a distal end of the wall at a predetermined angle. The lip may, for example, define a sealing flat sealing surface extending around an entire perimeter of an aperture into the cavity. The WRF canister may, for example, include a validation method including a placement of a pharmaceutical container within a vacuum chamber including a sensor. The method includes a correlation of a pharmaceutical leakage calibration to the sensor. The method includes a validation determination as a function of the predetermined correlation between a detection of a leaked substance and a weight change in the pharmaceutical canister over a predetermined period.
