摘要： Testing methods and equipment are provided for fast, non-destructive testing of the quality of seal and/or integrity of a package. According to certain embodiments, dynamic impact characterization is used to determine whether a loss of pressure due to a leak in the package occurs. The methods and equipment can be used in-line with product packaging processes. According to one embodiment, an initial pressure is applied to a package under test. A region of the package is impacted with a force sufficient to create a disturbance to the package while not destroying the package by using an impacting rod. Force sensors/transducers contact with the package and spaced a distance away from the impact region of the package detect a force signature from the impact. The existence of a leak is determined by evaluating the force signature.

摘要： An instrument for the measurement of vacuum within sealed packets 12, the packets 12 having a wall 14 that it can be deformed by the application of an external dynamic vacuum to an area thereof. The instrument has a detector head 18 for placement against the deformable wall 14 of the packet to apply the vacuum in a controlled manner to accomplish a limited deformation or lift of the wall 14, with this deformation or lift monitored by the application of light as via a bifurcated light pipe 20. Retro-reflected light through the light pipe is monitored with a photo detector 26. A change (e.g., a decrease) of retro-reflected light signals the wall movement such that the value of the dynamic vacuum applied through the head be to achieve this initiation of movement is equal to the vacuum within the packet 12. In a preferred embodiment a vacuum plate 44 is placed beneath the packet 12 to ensure that no deformation occurs on the reverse surface 16 of the packet. A vacuum can be applied to a recess in this vacuum plate, the value of which can be used to calibrate the vacuum transducer in the detector head.

摘要： Testing apparatus and processes are described for testing containers or selected portions thereof for leaks. The device includes container receivers for receiving a container. A support engages a surface of the container. The support includes a network of rigid support surfaces, preferably a screen shaped by a rigid base to conform to and engage the container surface. Open fluid passageways are interspersed within the network of rigid support surfaces which hold the container against deformation in response to applied pressure differential. A pressure differential across the surface being tested will result in passage of fluid through a leak in the test area. The fluid passageways facilitate free flow of the fluid from one side to the other. Flow of fluid will produce a detectable pressure differential between the two sides, quickly identifiable as a container leak. The support surfaces expand and contract to facilitate placement and removal of the container. A sealed test chamber is provided adjacent one surface of the container being tested. Differential pressure is applied to the test chamber to urge the tested container surface against the rigid support surface and influence fluid flow through the test surface and the open passages to be detected by an appropriate pressure sensor.

摘要： A check is provided of the gas pressure in a closed container having in its bottom wall a snap-action diaphragm of a type which assumes its concave-inward configuration when there is a vacuum of at least a predetermined level in the container, and assumes its convex-outward configuration when the vacuum level in the container is zero or less than said predetermined level. A test stand applies to the exterior of the diaphragm a vacuum sufficient normally to assure that it will assume its convex outward configuration, and then releases the applied vacuum to permit the diaphragm to snap to its concave-inward configuration. A proximity sensor produces an electrical signal representing the position of the diaphragm, which signal is differentiated to produce a signal indicating the speed of inward motion of the diaphragm. The differentiated signal is compared with a reference, and if it exceeds the reference, produces an indication that the inward snap-action has occurred and that the vacuum level in the container is adequate. The arrangement is applied to the high-speed checking of food containers for gas leaks.

摘要： The fluid tightness of containers having a first deformable section and a second deformable section spaced from the first deformable section is checked by changing the pressure applied to the first deformable section, preferably without causing fluid to flow through the first deformable section out of the container, and without changing the pressure applied to the second deformable section, thereby causing a deformation of the first deformable section and a change in pressure within the container; and thereafter monitoring a predetermined characteristic, preferably the position, of the second deformable section. This process can be used to check the fluid tightness of the containers with relatively fragile seals, for example, a foil lid of a food container without mechanical contact. Automated apparatus for carrying out this process is described.
