An aerosol container suitable for use as an aerosol dispenser. The aerosol container includes at least a valve and product delivery device joined to an outer container. The valve and product delivery device have respective annular welds or other seals joining the valve and product delivery to the outer container. The welds, or other seals may be concentric, with one circumscribing the other, in the same plane or different planes. Suitable product delivery devices include bags and dip tubes.

The invention relates in general terms to a device for production of a packaging precursor, wherein the packaging precursor consists to an extent of at least 80% by weight, based on the packaging precursor (1000), of a sheetlike composite, wherein the sheetlike composite includes: i. a composite plastic layer, ii. a composite carrier layer, iii. a first composite edge region, iv. a second composite edge region, wherein the device includes, as device constituents in a flow direction: a) a flat transport unit designed to transport the flat sheetlike composite, wherein the transport unit includes a transport surface designed to bear the composite; downstream of that b) a first heating unit designed to heat the first composite edge region, where the first heating unit includes energy release segments; downstream of that c) a contacting unit designed to bond the first composite edge region to the second composite edge region;
wherein the first heating unit is designed to release energy in the flow direction. The invention further relates to a method, to a packaging precursor obtainable by the method, to a packaging precursor and to a use of the device.

The invention relates to a packaged product or group of products, such as a candy, wherein said product or group of products has an elongated form, wherein the package comprises at least one film which encloses said product or group of products, and wherein part of said film extends from at least one outer end of the product or group of products, and wherein said part of the film is bent away from the direction of the axis of the elongated product or group of products back towards a part of the film that surrounds the product and is bonded therewith. The invention also relates to an easy opening arrangement for packaged products, and to an array or bandoleer of products with reduced packaging material.

An apparatus is configured to make containers from sheet material. The apparatus includes a supply station for supplying a film having at least one folded portion having three or more film flaps folded and superimposed with respect to each other; a welding station configured to receive the film. The welding station comprises a welding head configured for welding the folded portion of the film and forming a container defining a housing compartment; the welding head comprises a heater made of electrically conductive material whose electrical resistivity, at least in a predetermined temperature range, decreases upon the increase of the temperature of the same electrically conductive material.

A resin filler tube includes: a tubular body; a flange having a diameter greater than an outer diameter of the tubular body, a thickness greater than a thickness of the tubular body, and a predetermined width in an axial direction, and having a first axial end face forming a weld surface to be welded to an outer circumferential edge of an opening hole of a fuel tank; and a base-end-side reverse tapered portion which connects between an end of the tubular body on the fuel tank side and an end of an outer circumferential surface of the flange on a side opposite to the fuel tank side, and which is reversely tapered so as to increase a diameter toward the flange. The base-end-side reverse tapered portion has an inner diameter that is not less than an inner diameter of the tubular body over an entire range in the axial direction.
