According to an embodiment, a cap-closing apparatus includes, a holding mechanism section configured to be capable of holding a cap which is attached to an opening of a specimen container that is formed to be capable of containing a specimen, a moving mechanism section configured to move the cap, a rotating mechanism section configured to rotate the cap, a torque detector configured to detect a torque at a time of rotation, and a controller configured to control an amount of rotation of the rotating mechanism section, based on the torque detected by the torque detector.

Disclosed is a method of fastening a cap of a container, the method including: specifying a screw thread engagement point of a cap and a neck ring of a container; and aligning the engagement point with a fastening start position of the cap and fastening the cap to the neck ring, in which the specifying of the engagement point includes detecting the engagement point by rotating the cap in a reverse direction in a state where the cap is seated on the neck ring.

The present invention relates to a capping device for closing screw caps, comprising a motor and a power train so as to transmit force from the motor to the screw caps by means of the power train. The capping device comprises a control unit configured for dynamically adapting the operation of the motor, making use of a measured actual value of an operating parameter of the motor, a target closing torque and an actual closing torque model.

The packaging system according to the invention comprises a container (1), which includes a neck (2) defining an axis (X-X), and a stopper (10) for closing the neck, which includes a skirt (12) adapted to be fastened removably around the neck. In order to quickly and easily check that the stopper is positioned correctly on the neck when the container is closed, the invention provides means for visually checking that the system is in a closed configuration, predetermined afterwards by applying a preset stress for having the skirt cooperate with the neck, said means comprise both: first indicators (20, 22) of the angular position around the axis between the neck and the skirt, said first indicators being respectively borne by the neck and the skirt and being designed to be arranged with an angular spacing between them which is substantially equal to a first predetermined value when the packaging system is in the closed configuration, and second indicators (21, 23) of the position along the axis between the skirt and the neck, said second indicators being separate from the first indicators, borne respectively by the neck and by the skirt, and designed to be arranged parallel to each other with an axial spacing () between them which is below a second predetermined value when the packaging system is in the closed configuration.

An automated system for carrying out capping tests is provided. The system comprises electronic processor means, a first container for randomly arranged caps, a second container for randomly arranged preforms, a quality control device for caps and preforms, a robotic device for identifying, selecting and picking a cap from the first container and a preform from the second container, and for subsequently placing the cap and the preform into corresponding seats of the quality control device, a capping control device, arranged downstream of the quality control device and configured for carrying out at least one cycle of application of the cap to the preform, so as to obtain a sample, and ascertaining one or more characteristics of the sample on the basis of mechanical and/or physical quantities detected during the application cycle, and a marking device for affixing, to each tested sample, a marking identifying characteristics ascertained in respect thereof.

Disclosed is a method for inspecting containers provided with closures for checking a sealing function between the closure and a container provided therewith in order to check the sealing function, the at least one spatially resolved image is recorded by the at least one image recording device in such a way that, viewed in the closure direction, a relative position of the closure with respect to the container provided therewith is depicted, and an image evaluation device determines, on the basis of the relative position depicted in the at least one spatially resolved image, at least one sealing variable that is characteristic of performing the sealing function.

The present invention relates to a method for the particularly automated measurement of a closing angle of a lid (110) of a container (100) particularly a bottle lid (110) with a screw thread (120) comprising the following steps: a) Positioning of the container (100) and determining of a starting position, b) Turning of the lid (110) from a closing position (I) into the direction of an open position (II) of the lid (110), c) Detection of an open position (II) of the lid (110) and a corresponding open position angle , d) Calculation of the closing angle of the lid (110) on the basis of the open position angle and particularly, a lid parameter.

Implementations disclose methods and devices for closure control of containers. A method includes performing, by an inspection apparatus, optical 3D measuring of a closed container, the closed container comprising a closure coupled to the container; generating, by the inspection apparatus, 3D data based on the optical 3D measuring; and processing, by an evaluation device, the 3D data to determine at least one of tightness or correct seating of the closure relative to the container.

Disclosed is a method for inspecting containers provided with container closures, wherein the container closure has a closure cap screwed onto a mouth of the container, a securing device arranged on the container below the mouth in a longitudinal direction of the container, a connecting strand that connects the securing device to the closure cap, a first fastening section where the connecting strand is fastened to the closure cap, and a second fastening section with which the connecting strand is arranged on the securing device, wherein the containers are transported by a transport device and inspected by an inspection unit, wherein a first marking located on the container is recorded in order to determine the rotational position of the container closure from a position of the connecting strand and/or a position of at least one fastening section.

The torque which is required to open a plastic screw closure which is screwed onto a bottle is determined without contact by the rotation position of the screwed-on plastic screw closure in relation to the bottle being established. The rotation position is established by evaluating an image on the basis of a mark on the bottle and a mark on the screw closure. Ventilation slots which interrupt the turns of the screw thread on the bottle neck can be used as the mark on the bottle, and a predetermined breaking point on a securing ring of the screw closure can be used as the mark on the screw closure.
