Systems and methods for detecting syringe seal defects are described, including associated syringe stopper designs having seal areas and indicating areas, as well as associated inspection systems and methods for optical imaging and analysis for syringe seal defects in dry and wet syringes.

An inspection system for detecting defects in structures of containers, such as beverage bottles, using a light transmission system configured to transmit light through a portion of a bottle. The abstract of the disclosure is submitted herewith as required by 37 C.F.R. 1.72(b). As stated in 37 C.F.R. 1.72(b): A brief abstract of the technical disclosure in the specification must commence on a separate sheet, preferably following the claims, under the heading Abstract of the Disclosure. The purpose of the abstract is to enable the Patent and Trademark Office and the public generally to determine quickly from a cursory inspection the nature and gist of the technical disclosure. The abstract shall not be used for interpreting the scope of the claims. Therefore, any statements made relating to the abstract are not intended to limit the claims in any manner and should not be interpreted as limiting the claims in any manner.

Disclosed are a method and an accompanying system for inspecting objects (5) provided with a gas-barrier layer. The objects have at least one base layer (5a) of a first material, polyethylene or polypropylene, for example, and at least one gas-barrier layer of a different material, EVA or EVOH, for example. An image-recording module (6), such as an infrared camera, records an image of each object (5) and processes the images by means of a processing module (7) in such a way that faulty objects (5) are detected and eliminated. More specifically, the image recording module (6) creates the image of each object (5) within the invisible light spectrum, and the processing module (7) then examines the recorded image, wherein the presence, the absence or the thickness of the gas-barrier layer is determined on the basis of the image.

A method for detecting, on the finish of containers, defects in a horizontal mold seal of the container includes the steps of disposing the container between a light source and a camera and ensuring the rotation of the container on itself according to one rotational revolution. The camera acquires, at each increment of rotation of the container, an image so that the number of images per rotational revolution is greater than 36. The images captured for each container are analyzed such that the profile of the finish edge is detected in each image, the profiles of the finish edge of the images are compared with a reference profile of the finish edge so as to detect deviations between these profiles, and a defect in the horizontal mold seal for a container is detected when at least one image of said container has a deviation.

The present invention relates to a seal inspection device for inspecting seals of a container. Specifically, according to an embodiment of the present invention, provided is the seal inspection device for inspecting the sealing of a container, comprising: an irradiation unit for irradiating light along an optical path extending in a first direction; a sensor unit for detecting the light traveling along the optical path; and a pressing module for pressing the sealing of the container, wherein the pressing module includes a plurality of pressing units arranged on the optical path, and the pressing unit can be selectively located at a first position for blocking the light from reaching the sensor unit and a second position for allowing the light to reach the sensor unit.

A device and method for inspecting glass containers and particularly the finish of glass containers is provided. The glass container inspection device includes a rotator rotates a glass container located in an inspection location at least 360 degrees. A first laser source produces a first laser beam which is directed towards the inspection location to form an angle of incidence with the selected glass container being greater than or equal to a critical angle for producing internal reflection of the first laser beam within the selected glass container. A camera is directed at the inspection location to detect light that escapes from the selected glass container as a result of the internally reflected laser beam intersecting a defect in the selected glass container.

A container inspection arrangement for inspecting glass and/or plastic containers, and a method of inspecting glass and/or plastic containers. The abstract of the disclosure is submitted herewith as required by 37 C.F.R. 1.72(b). As stated in 37 C.F.R. 1.72(b): A brief abstract of the technical disclosure in the specification must commence on a separate sheet, preferably following the claims, under the heading Abstract of the Disclosure. The purpose of the abstract is to enable the Patent and Trademark Office and the public generally to determine quickly from a cursory inspection the nature and gist of the technical disclosure. The abstract shall not be used for interpreting the scope of the claims. Therefore, any statements made relating to the abstract are not intended to limit the claims in any manner and should not be interpreted as limiting the claims in any manner.

An inspection device for monitoring bottles includes a lighting unit, a color-sensitive camera, and a control-and-evaluation unit. The lighting unit is arranged above a transport path of bottles to be examined and has a light-source circuit-board having light sources that emit light having a light-source color. The control-and-evaluation unit changes the light-source color to a bottle color that is determined in a region of a mouth of a bottle.

A method for inspecting containers with closures with a cap portion and a circumferential edge extending around the mouth of the containers. The containers are transported along a transport path by a transport device. During transport, the mouth regions of the containers with closures are illuminated by an illumination device, and at least one image recording device records at least one image of the mouth regions of the containers with closures, and records at least one spatially resolved image of a portion of the circumferential edge and one structure on the circumferential edge is detected, and, at least one value of this structure, a value characteristic of a relative position of the closure relative to the container and/or relative to the rotationally symmetrical element and/or of the closure is determined.

A container inspection device includes: an irradiator that irradiates, with light, containers transferred in an arrangement of multiple lines; an imaging sensor that images the radiated light; optical path conversion sheets that convert an optical path of the light; an imaging optical system that forms an image of the light along the converted optical path onto the imaging sensor; and a hardware processor that identifies whether the side walls include defective based on image data obtained from the light imaged on the imaging sensor. The optical path conversion sheets are laid across the multiple lines. The optical path conversion sheets respectively correspond to the side wall areas, and each of the optical path conversion sheets converts the optical path of the light reflected from or transmitted through a corresponding one of the side wall areas into an optical path along an optical axis of the imaging optical system.
