The present invention is directed to a process for manufacturing a flexible package suitable for containing a food or beverage ingredient and suitable for use with a food or beverage preparation machine, wherein said process comprises punching a flexible flat blank sheet between a plunger and a cavity that are movable relative to one another. According to the invention, the plunger has a concave end side and convex lateral sides, and the profile curvature of its end side is identical to the profile curvature of each of its lateral sides.

A bag-making and packaging machine forms a sheet-like film into a tubular shape and transversely seals the film to manufacture bags containing articles. The bag-making and packaging machine includes a transverse sealing mechanism and a control unit. The transverse sealing mechanism pinches and transversely seals the tubular film that has been formed into a tubular shape to form a transverse seal portion. The control unit determines whether or not there is jamming in the transverse seal portion and, in a case where it has determined that there is jamming, switches between a first bag-making process to continue bag-making operation and a second bag-making process to stop bag-making operation based on a jamming state.

There is provided a plastic film bag that includes: a front panel; and a back panel affixed to the front panel along edges of the front panel and back panel. The front panel, back panel, or both, define at least one primary tear notch and a primary tear line terminating at the primary tear notch. A plurality of secondary tear mechanisms are defined at edges within the primary tear notch. In some cases, the plurality of secondary tear mechanisms include notches spaced along a boundary of the edge defining the primary tear notch, the secondary notches smaller in size than the primary tear notch.

The invention relates to a device for welding a connection region of a film to a connection part having an axial direction. In the case of conventional devices, there is the risk of steep workpiece edges causing uncontrolled weak spots in the film and in the weld seam. According to the invention, the film is extended in a controlled manner such that the film has a length reserve. The film is extended in such a way that the film has a deformation cross-section that runs out such that the deformation is not visible on the final product. In this connection, the invention further relates to a use of a film, to a method for welding, to a method for producing bags, to a system for producing bags, and to a bag.

The invention concerns a pack (1) with an inner volume (2) in which a food or beverage ingredient (7) is stored and in which a beverage is produced when water is introduced inside, said inner volume (2) being defined by sheets of material (10) joined to one another at their edges and said inner volume (2) presenting a generally plane shape defining a plane (P) vertically oriented during beverage production, said pack comprising at least one inlet (3) for introducing water in the inner volume and at least one outlet (4) for delivering the beverage from said inner volume, said water inlet and said beverage outlet being positioned at the bottom of the pack and being at least partially positioned between two joined edges of the sheets of material (10), the external end (xx) of the water inlet (3) being oriented essentially perpendicularly to the plane (P) defined by the inner volume (2), and wherein the internal design of the beverage outlet is configured for controlling the properties of the beverage.

Pack (1) with an inner volume (2) in which at least two different food or beverage ingredients (71, 72) are stored and in which a beverage is produced when water is introduced inside, said inner volume (2) being defined by sheets of material (10) joined to one another at their edges and said inner volume (2) presenting a generally plane shape defining a plane (P) vertically oriented during beverage production, said pack comprising at least one inlet (3) for introducing water in the inner volume and at least one outlet (4) for delivering the beverage from said inner volume, said water inlet and said beverage outlet being positioned between two joined edges of the sheets of material (10), and wherein the inner volume (2) includes a plurality of compartments (21, 22), the compartments being separated by at least one releasable or separable bond (6).

A machine for forming bags with infusion or extraction products includes a station for forming and feeding single sheets; a U-shaped folding station for folding the sheet; a unit for sealing the two lateral edges the sheet to create a bag with a closed bottom and side and an open end opposite the bottom. A second carousel includes radial grippers each configured to receive a bag. A dosing station includes a first device for dosing a first product along a dosing trajectory towards the opening and a second dosing device for dosing a second product. A transporting element positioned between the dosing devices includes a container for receiving the second product. The transporting element moves the container from a second product dosing position to a position for unloading the second product coinciding with the dosing trajectory from where the container discharges the dose of the second product into the bag.
