Abstract: The present invention relates to the technical field of packaging technology. One or a plurality of membranes is to be sealingly attached to an inner surface of a container making use of a small number of working steps. For this purpose, a tool comprising a force transmission unit (10), a deflection unit (20) and a positioning element (30) is suggested. The force transmission unit (10) is coupled to the deflection unit (20) and the positioning element (30), so that a force can be transmitted from the force transmission unit (10) to the deflection unit (20) and/or the positioning element (30). At least a portion of the deflection unit (20) is deflectable with a radial component. The positioning element (30) is adapted to allow a flow of gas therethrough, so as to pick up and hold the membrane (33).

Abstract: The present invention relates to a filler machine and method. The filler machine and method allow efficient and/or accurate filling of containers such as bottles, and have particular application to filling bottles or similar containers with carbonated beverages.

Abstract: Cap holder means which holds the inner peripheral surface of a cap has an outer diameter which may be shrunk to a value less than and expanded to another value greater than the diameter of the inner peripheral surface of the cap. When the cap holder means assumes a shrunk condition in which the outer diameter thereof is less than the diameter of the inner peripheral surface of the cap, the cap holder means is capable of smoothly receiving a cap from a cap feeder. Upon receiving a cap, the cap holder means may be changed to an expanded condition presenting an outer diameter greater than the diameter of the inner peripheral surface of the cap, thereby allowing caps of any varying internal diameter to be centered with respect to the cap holder means. This allows a smooth delivery of the cap from the cap holder means to a capping head.

Abstract: The invention relates to a contact pressure element for metal foil blanks laid around the neck and top of bottles (3) in a labelling machine. Retained by a retaining ring (5) in front of the opening of a casing (1) having a bell-shaped inner wall (7) is a resilient plate (2) whose front side facing the end face of the bottle (3) is made of an open-pored resilient foamed plastics, the rear side of the plate (2) being constructed with closed pores and its peripheral edge being formed with an annular bead (8). When the contact pressure element makes an axial movement towards the end face of the bottle (3), the plate (2) yields to the axial pressure, its rear side rolling down the bell-shaped inner wall (7) in the zone of the annular bead (8), so that the front side of the plate (2) is brought into radial contact pressure with the side of the bottle top in the zone of the annular bead (8). Such contact pressure is produced without folding the plate (2) and substantially without warping.

Abstract: A plunger (4) for joining an inner workpiece (7) to an outer tubular workpiece (2) is disclosed. The plunger includes an expansion element (9) which engages the inner workpiece and crimps it to the outer workpiece. The expansion element (9) is an annular cup-shaped resilient element which is mounted on a part (21) which is movable relative to a body (8) and to a bottom plate (16). The body (8) and its bottom plate (16) are provided with guide surfaces which are spaced apart to provide a space through which the expansion element may pass upon movement of member 21. The guide surfaces constrain the resilient expansion element to move into pressure applying engagement with the inner workpiece.

Abstract: A device for smoothing and pressing down in labeling machines, intended for the point of a blank of foil wrapped around the neck and head of a bottle with the point projecting at the head, and having a pot-like housing that can be moved axially against the head of the bottle and accommodates an elastic sponge structure. To allow the device to handle the blank of foil gently, apply it uniform and smooth to the head of bottle even in the vicinity of depressed zones of the head, and to prolong its life, the face of the sponge structure toward the head of the bottle has a recess that in the pressing-down position embraces at least the head of the bottle on all sides subject to slight tension.

Abstract: An apparatus for inserting an internal lid (6, 7) in a tubular formed container (1) and for sealed connections of the lid to the inner of the container tube by constant heat welding, high frequency welding or ultrasonic welding and comprising a carrier (8) for holding the container tube (1) while introducing and weld connection the lid (6, 7), a support provided above the carrier (8) for positioning a plane punched out lid blank having a larger outer periphery than the inner periphery of the container tube, a piston means (16) pressing the lid blank into the container tube while folding a narrow edge rim (7) upwards from the lid plane (6) and in which the piston means comprises a lower piston part (18) and an upper piston part (20) which are axially movable in relation to each other and an expandable means (19) between said two piston parts (18, 20) which expandable means is pressed radially outwards when the two piston parts (18, 20) are compressed.

Abstract: A method and an apparatus for manufacturing a tin-like container comprising a sleeve formed body or jacket (1) and at least one end closure (2, 3), in which the jacket (1) and the end closure or the end closures (2, 3) at the interior side of the container has a layer (5) of a constant heat weldable, high frequence weldable or ultrasonic weldable material, and in which the container is closed under sealed condition in that the end closure (2, 3) is formed with an edge flange extending all around the end closure and is introduced in the jacket (1) and is welded thereto. The introduction of the end closure (2, 3) in the jacket (1) is made by means of a press piston (14) having a press cone (15) which is formed with an expandable means (15d; 29).

Abstract: This invention provides substitute capping heads to apply a threaded closure on a bottle neck through the utilization of existing machines which were designed to apply an aluminum closure on a bottle neck by in situ formation of the threads in an aluminum shell. The modified capping heads embodying this invention utilize the same rotational and vertical movements of the capping heads relative to the containers, but effect a frictional engagement with a pre-formed, internally threaded plastic closure to effect the screwing of such closure onto a bottle neck with the effective application torque being limited by a slip clutch incorporated in the drive train of the modified capping head. Such clutch is isolated from ambient humidity conditions, and in some modifications operates in an oil bath.
