A method and device for sealing gas in a gas compartment-equipped bag, in which pressurized gas discharge outlets are provided in the distal ends of a horn and an anvil of an ultrasonic sealing device, and such horn and anvil used for ultrasonic sealing are also used as gas-discharging nozzles. The distal ends of the horn and the anvil are placed against a cutout of a gas compartment of a bag, a gas is discharged into the gas compartment from the discharge outlets, the films surrounding the cutout are being clamped by the horn and the anvil while gas discharging is in progress, and then the gas compartment is ultrasonically sealed by the horn and the anvil to trap the gas inside.

The present invention relates to a method for portion-packing of an oral pouched snuff product (1′, 1″). The method comprises a) supplying and advancing a tubular web (19, 19′, 19″) of packaging material enveloping a continuous feed (23, 23′, 23a″, 23b″) of filling material in a direction of travel (L), b) forming transverse seals (39) in the tubular web across the continuous feed of filling material by means of ultrasonic welding, the transverse seals extending in a transverse direction (T) being perpendicular to the direction of travel. The present invention further relates to an arrangement (17, 17′, 17″) for portion-packing of an oral pouched snuff product.

The present disclosure is directed to an inflatable-cushion inflation and sealing device. The device includes an inflation assembly configured for insertion between first and second overlapping film plies. The inflation assembly includes a fluid conduit configured to direct a fluid in between the plies to form one or more cushions. The fluid conduit includes a nozzle. The inflation assembly includes a cutting member. The cutting member includes a blade holder with a blade and a blade guard mounted thereon. The blade guard has a safety position in which the blade is covered and a retracted position in which the blade is exposed. Installation of the blade holder onto the inflation assembly automatically positions the blade in the working position with the blade guard retracted. Removing the tray from the inflation assembly automatically positions the blade in the safety position by covering the blade with the blade guard.

A machine for making filter bags of different shapes for infusion products includes: a wheel defining a work surface and rotating about a relative axis; feed stations for placing tags on the work surface, a continuous thread, along a weave path, and a strip of filter material superposing the weave of thread and the tag. A sealing device is located downstream of the feed stations for sealing between the thread, tag and strip of filter material. A feed device moving the strip along a feed line is positioned downstream of the wheel. A station introduces a dose of infusion product in bag and closes the bag. The feed device has two feed rollers, for unwinding the strip, controlled by a control system for adjusting the speed of rotation of the feed rollers as a function of the length of the filter material needed to form the bag.

An ultrasonic systems and methods for sealing complex interfaces or for metal forming. Complex interfaces, such as a Gable top, have multiple and a variety of layers across the interface, or an oval or round spout having a complex geometry. An example system includes two ultrasonic horns arranged opposite a gap between which the interface is provided. The frequency and phase of the ultrasonic energy are synchronized as the energy is applied simultaneously while the interface is pressed between a jaw and the energy is applied to both sides of the interface. Another example system includes two ultrasonic transducers synchronized in frequency and phase and used to vibrate a horn mechanically to facilitate a sealing or welding interface or to assist in a metal-forming process.

A modular stand-alone ultrasonic bag sealing system has an ultrasonic sealer assembly that utilizes a sonotrode, an anvil that are actuated together to form a bag seal in a bag configured therebetween. The system also has an integral control system that is physically configured on the housing of the system and runs a control software. The control software is configured to control the ultrasonic sealer assembly to close and open to seal bags. The controller may have a plurality of signal inputs for receiving input signals from a bag feeder assembly or from an auxiliary machine. The system may also have an integral bag feeder assembly that has an index roller for feeding a bag to the ultrasonic sealer assembly. The system is configured for quick integration into a process line and has versatility of communication through the control software and signal inputs and outputs.

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.

A capsule or container is provided having optimized recycling attributes. The capsule is provided for use in a machine for preparing a consumable product from capsules. The capsule includes a body that defines an interior space with an opening. A cover is disposed over the opening. A filter is disposed in the interior space to define a chamber between the filter and the cover. The body, filter and cover are preferably formed of the same substantially pure polymer material. Ingredients are disposed in the interior space for preparing a desired product. A hinge is provided to tether the cover to the body. The cover is attached with a peelable seal to the body so that cover may be peeled away from the body while remaining tethered at the hinge.

A process is provided for making a beverage capsule for use in a beverage preparing machine. The process includes the steps of: sealing a filter to an interior surface of a body for the beverage capsule to define an ingredients chamber; depositing a desired volume of desired ingredients into the ingredients chamber; and sealing a cover to the body to cover the opening. The cover is sealed to the body to define a hinge zone and a peel zone, wherein the hinge zone has a stronger seal than the peel zone.

Manufacturing capsules, comprising preparing a first and a second capsule element, at least the first element containing a cavity, each element, being provided with a peripheral ring, bringing the elements together, so that the rings are superimposed, placing the two elements between a sonotrode and an anvil, the anvil containing an anvil recess and a striking surface, surrounding the anvil recess, the sonotrode including a sonotrode recess, with the same cross-section as the anvil recess, and a working surface surrounding the sonotrode recess, wherein the striking and working surfaces are configures to come into contact with each other on a working area, extending around the recesses, clamping the rings between the working surface and the striking surface by the proximity of a sonotrode and the anvil, activating the sonotrode and directing the ultrasound towards the anvil, whilst maintaining the clamping action, wherein the rings are detached from the capsule.
