A fully compostable beverage capsule may be produced by improving the seal strength between the capsule and its lid. Additionally, the lid itself may be made more resistant to the stress that occurs during brewing. In this invention, the lidding material is cut one or more times to produce a pattern similar to the blades of a pinwheel. The sections or “blades” are then overlapped and energetically welded to one another and joined to the beverage capsule. In this process, the double thickness of lidding material improves the seal between the lidding and the capsule. Each “blade” of the lidding has its own point of attachment to the capsule, which helps to isolate any stress that may occur during the beverage brewing process. As a result, the lidding as a whole remains securely attached to the capsule, even if one or two blades experience sufficient stress to trigger delamination.

A fully compostable beverage capsule may be produced by improving the seal strength between the capsule and its lid. In this invention, a number of protruding tabs are added to the upper and/or lower edges of the capsule. The lidding is then attached to the capsule via an energetic welding process, such as ultrasonic welding. In this process, the protruding tabs are folded over the edge of the capsule and deformed, increasing the surface area contact between the capsule and its lidding. Acting similarly to a swage fitting, these spikes will improve the strength of the seal that forms between the lidding and the capsule.

A sealing device for forming a transversal seal to a tetrahedral packaging container is provided. The sealing device comprises a sealing element and an imprint ruler arranged at a longitudinal distance from the sealing element. The sealing element is configured to provide a top transversal seal to a packaging container while the imprint ruler is configured to provide a transversal imprint to the same packaging container.

A device for sealing packages, including a product feed and a packaging feed for a tubular packaging material; and a method for sealing packages. Such devices are used, for example, as tubular bag machines. The packages can be produced by type for improved recyclability while simultaneously maintaining a high load-bearing capacity of the package closures with the aid of a closure element made of the same material as the rest of the package by welding the closure element and the package in the closure region.

A sealing system (100) for sealing a packaging material is disclosed comprising an independently movable sealing device (101) being movably mounted on a track (102), a power generator (105) in communication with the sealing device (101) to supply a power signal (p1) at a frequency for said sealing over a power communication line (106), the sealing device (101) comprising a housing (107), a detection device (108) arranged in the housing (107) to register detection data of an environment therein and/or of sealing parameters associated with said sealing, and a transmitter (109) connected to the detection device (108), the transmitter comprising an encoder (110) to convert the detection data to at least one frequency pulse (p2), whereby the transmitter (109) communicates the at least one frequency pulse as a detection signal to a receiver (111) over the power communication line (106).

A machine for producing a container from a preform having a body and a neck defining an inner cylindrical opening. The machine includes a container forming and filling station where the preform is placed in a mold having a molding cavity and a forming liquid is injected into the preform thereby forming and filling the container with a liquid. Prior to forming of the container, an extension device is attached to the neck of the preform thereby forming an assembly. The extension device includes a connection part for attaching to the preform and an extension part defining an inner opening extending in the continuity of the inner opening of the neck of the preform. The extension device remains attached to the neck of the preform at least during the forming and the filling of the container.

A determination device includes an imager that captures an image of an object subjected to a sealing process by use of an adhesive and that acquires a distribution of an intensity of energy emitted from the adhesive, and a determiner that calculates a change over time in the intensity of the energy emitted from the adhesive based on a first distribution indicating the distribution acquired from an image captured by the imager at a first time point and a second distribution indicating the distribution acquired from an image captured by the imager at a second time point later than the first time point and that determines the quality of sealing based on the calculated change over time.

An ultrasonic welding system. The system includes an ultrasonic transducer assembly having a horn and a first transducer and a second transducer arranged to impart ultrasonic energy into the horn. The horn has a first part-interfacing surface and a second part-interfacing surface opposite the first part-interfacing surface. An actuator assembly is operatively coupled to the ultrasonic transducer assembly and configured to cause rotation of the horn. A controller is configured to: cause the actuator assembly to rotate the horn so that the first part-interfacing surface applies the ultrasonic energy to a first part along an entire length of the first part-interface surface while a first ultrasonic energy is applied through the horn via the first transducer to cause the first part-interfacing surface to vibrate back and forth along its entire length as the first ultrasonic energy is applied by the first transducer to the horn.

An induction sealing device for induction welding of a packaging material is disclosed. In some embodiments, the induction sealing device comprises an inductor coil configured to induce an alternating current in a metal foil of the packaging material for inductive heating thereof. The induction sealing device can further comprise a magnetic insert encapsulating the inductor coil apart from an outer portion of the inductor coil, and the outer portion can be arranged towards the packaging material to be sealed. In some embodiments, the magnetic insert is configured to interact with the packaging material to be sealed via at least one interactive surface. In some embodiments, the induction sealing device comprises a connection unit. The connection unit can comprise a parallel connection configured to connect to the inductor coil and to an AC power source.
