A container has a tube-like or tubular shell, which is sealed against the surrounding atmosphere and has a weld seam at at least one end. For checking the tightness of the container the internal pressure in an interior space of the container is increased by means of external action and the thereby ensuing deformation of the weld seam is detected. Provisions are made in this connection for the weld seam to be clamped between clamping elements before increasing the internal pressure only in a partial area of its surface, which has a distance from the end of the weld seam facing the interior space.

A flexible tube skirt (10) has a primary film (20) and a decorative film (30), wherein the decorative film (30) has a decoration substrate and a sealable outer layer (33) The decoration substrate is applied on all of at least one of the surfaces of the primary film (20) and is below the sealable outer layer (33). The flexible tube skirt may be used in a flexible tube.

A container includes a container closure and a multi-layer side wall coupled to the container closure. A method includes forming the container with the multi-layer side wall. The multi-layer sidewall includes a film layer and a foamed layer coupled to the film layer to provide the multi-layer sidewall.

In an injection mould, a plastic injection-moulded product is manufactured. The plastic injection-moulded product comprises a tubular body, a neck part and a head part. The injection mould comprises three mould parts, which are displaceable with respect to each other between a closed position and an open position. The first mould part comprises a first mould cavity for producing the neck part and the head part. The second mould part comprises a second mould cavity for producing the tubular body. The third mould part comprises a core body. In the open position, a neck label is arranged in the first mould cavity of the first mould part and a peripheral label is arranged in the second mould part. Subsequently, the mould parts are moved to the closed position to form a closed mould cavity. By supplying plastic, the plastic injection-moulded product is produced. The labels are integrally formed in the plastic injection-moulded product (in-mould labelling).

Provided is a method for making barrier tube shoulders. The method includes forming a parison from a multi-layer laminated structure having an inner layer that faces an interior of the parison, an outer layer comprising an exterior surface of the parison, and an interdisposed layer between the inner layer and the outer layer, wherein the interdisposed layer is a flavor barrier layer. The method also includes providing an extrusion blow molding (EBM) mold comprising at least one cavity shaped as a barrier tube shoulder, positioning the parison in the EBM mold, and blow molding the parison such that the parison substantially conforms to the EBM mold to form a barrier tube shoulder having the barrier layer.

A moulding method and device for moulding products from a dose of molten material, wherein the movement of a part of the mould towards another part of the mould is controlled in position and the compression movement represents between 5% and 40% of the cycle time.

An injection-molding press for overmolding a second part onto a first part (8) includes a movable portion and a fixed portion, with a first mold element (11, 12) on one of the press portions and a second mold element (20) on the other press portion so as to form a cavity (C) between the mold portions when the press is closed. The first mold portion (11, 12) has a first support surface (125a) movable in the first mold portion and the second mold portion (20) has a second support surface (22a). In the closed position of the press with a first part (8) in the first mold portion and the first support surface (125a) advanced in the working position, at least a portion (8b) of the front end of the first part (8) is clamped between the two support surfaces (125a, 22a), forming a tight seal for the cavity (C).

Rotary indexing device for manufacturing packaging tubes, comprising an indexing turntable (3) mounted in a rotary manner about an axis (9), and mandrels (4) and respective supports (14) secured to said turntable (3) and disposed radially with respect to said axis (9); radial actuating means (10, 11) for moving the mandrels (4) in a direction perpendicular to said axis (9) and linear guide means (13) for moving the mandrels (4) in a direction perpendicular to said axis (9); characterized in that the mandrels and respective supports (14), the radial actuating means (10, 11) and the linear guide means (13) are disposed in a direction parallel to said axis (9).

An applicator head for a dispenser for cosmetic or pharmaceutical liquids and foodstuffs, having a pump device with a pump chamber, an inlet valve arranged between a suction intake and the pump chamber, an outlet valve arranged between the pump chamber and an applicator opening, and an actuating arrangement with the aid of which an inner volume of the pump chamber is changed. At least two of the three components from the group including the outlet valve, the inlet valve, and the actuating arrangement each include at least one elastic section formed from an elastically deformable material, the elastic sections of the at least two components are integral parts of an interlinked elastic component section of a uniform elastic material having a connection area between the at least two components, and the connection area, in the installed state of the application head, is in an elastically deformed state.

SUMMARY

The invention relates to a method and a device for expanding at least a section of an initial tube blank (2) made of plastic or metal in such a way that an expanded tube blank (1) is obtained which tapers in the direction of an end of the tube blank that is not affected by the expansion process. The initial tube blank is fixed in a holding device (4) in a first position (6a), a first mandrel (3) is inserted into the initial tube blank, pressed therein and held in the pressed-in position for a predetermined heating time period, so that at least a part of the tube blank is expanded, and finally the first mandrel is pulled out of the expanded tube blank (1), wherein, when the first mandrel is pulled out of the tube blank, either compressed air is blown into the interior of the expanded tube blank through the first mandrel provided with at least one corresponding first air channel (5), or the expanded tube blank is mechanically stripped off.
