A closer for containers, in particular bottles, with a closing head acting in a clean room and with an electric motor comprising at least one rotor and at least one stator, with the closing head connected with the rotor, and an element for clean room separation is formed between the rotor and the stator.

A laboratory capper, decapper or combination capper/decapper includes a deck containing with a nest designed to hold an SBS-formatted tube storage rack, and a bit exchange magazine assembly containing one or more sets of adapter bits. The adapter bits are mounted on and unloaded from motor driven fittings, and are exchanged in order to cap or decap laboratory sample tubes or vials that have different head configurations. The bit exchange magazine assembly enables the bit to be exchanged robotically.

A capping unit (100) for articles such as containers and/or bottles in general, of the type including at least one capping group (3) bearing one or more capping heads (8) for screwing caps (6) or capsules on the articles moved by at least one transport line (4). It includes at least one capping heads store (19), adapted to retain a series of capping heads (8), in order to allow the rapid and automatic exchange and substitution of the spindles (25) of the capping group (3); the capping group (3) being moved by an associated motorization, up to reaching the store (19) such to store and pick up, automatically from the group (3) itself the suitable capping head (8) as a function of the size of the caps (6) or capsules to be screwed.

The invention relate generally to a tightening mechanism for a bottle filling and capping system, and a bottle neck configuration. More specifically, the invention includes a machine for tightening plastic caps onto the threaded necks of plastic bottles, and bottle neck configuration that facilitates the capping process, both of which result in a simple and effective capping operation. A conveying assembly moves the bottle in a circular path where the neck of the bottle and the cap are brought together by moving the bottle under a cap that is loosely held at a particular elevation and angle by a feeder mechanism. The conveying system constricts the rotational movement of the bottle, and a neck support stabilizes the neck of the bottle vertically, as the cap is pressed onto the neck initially by a roller. A capping station in a bottle filling line is comprised of a spring biased toothed finger that engage the peripheral edge of the caps as the bottles are conveyed through the machine. Depending on various factors such as the number and circumferential length of the threads on the cap and bottle a second roller and second toothed finger will be used to complete the tightening process. When a capped bottle exits the capping station, the cap is fully engaged with the bottle in that it is tightened and in its final position relative to the bottle.

A closing machine for closing containers has closing stations. Each station has a closer tool, a magnetically acting coupling element, a drive space, a product space, a linear drive, and a driver. The magnetically acting coupling element has inner and outer magnet elements. The drive space is formed separately from the product space. The linear guide positively drives the outer magnet element. The driver positively carries along said closer tool in a required height movement.

An applying unit for applying lids of opening devices to spouts of packages comprises a plurality of applying devices arranged for applying the lids to the spouts, a plurality of transfer arrangements, each transfer arrangement supporting a corresponding applying device and being movable along a track arrangement, wherein the transfer arrangements are self-movable along the track arrangement and are movable independently from each other along the track arrangement.

A system and method for a self-actuating, mechanically-biased container restraint. The system requires no computer-aided control or timing, nor is any external power source needed, other than the force exerted as a container is inserted into the restraint. The system relies upon an assembly including mechanically-biased pivoting levers, each of which has a horizontal element and a vertical element. All actuation occurs as the base of an inserted container comes into contact with the upper surface of the horizontal elements of multiple pivoted levers positioned at the base of a channel adapted to serve as a guide for the inserted tube. The levers are biased in this elevated position by mechanical means, such as a spring. As the inserted tube presses the horizontal members downward, the top portions of the vertical members are pivoted inward toward the container's exterior. Friction pads situated upon the interior surface of each vertical element are brought into contact with the exterior of the container, thereby gripping it. This gripping action holds the container with sufficient friction to permit the removal or attachment of a screw cap. Further embodiments of the invention include a mechanically biased platform supporting the channel and the pivoting levers. This base is biased and positioned to permit the channel and the pivoting lever assembly to be translated downward against the force biasing the platform and translate through the body of the container restraint. This further advancement of container, the channel and the lever assembly cause the pivoting levers to assume fully engaged gripping positions, and brings the vertical elements of the levers (and flexible friction pads upon them) into full upright positions. In this position the friction pads apply a maximum static friction force to the exterior of the container.

A sealing and pressure dosing apparatus, and container filling method, including a capping machine (102) which receives containers (1). Closures (80) are applied to the containers (1) immediately following the raising of pressure within the containers (1) by a pressure dosing system in a pressure sealing chamber (84). Preferably a cooling system is integrated with the capping machine.

An apparatus for automated capping and de-capping of test tubes having an ejector pin system for individualized cap ejection.

A closing apparatus for closing a container with a container closure, for example for closing a container with a screw cap in a beverage filling plant, includes a gripping mechanism for gripping the container closure with at least one gripping arm pivotable about a bearing, an actuating unit for actuating the gripping mechanism, and a detection unit for detecting a stroke of a stroke element of the actuating unit acting on the gripping mechanism. A corresponding method is also described.
