A flexible container incorporating flexible front and rear sheets with a perimeter seal in which at least one length or section of the perimeter seal can include a seal weld that has both a permanent seal section and a pressure absorbing seal section. The pressure absorbing seal section is configured to peel, fail, or split when the flexible container, filled with a solution or liquid, is dropped onto a hard surface to thereby absorb the impact of the drop. The flexible container can be provided with one or more dispensing and/or additive ports or without any port. The flexible container may include more than one compartments with a peelable seal separating two adjoining compartments of the flexible container.

The magnetic insert (102) is configured to interact with the packaging material to be sealed via at least one interactive surface (104). The induction sealing device (100) comprises a connection unit (105). The connection unit (105) comprises a parallel connection (106) to the inductor coil (101) and is configured for connection to an AC power source. A corresponding method (200) of manufacturing an induction sealing device (100) is also disclosed.

Tapping assembly for a beverage, including container including a first and second container, wherein the first container has a neck portion and the second container is suspended in the first container, from the neck portion thereof. A neck region of the container is provided with at least one opening in a side wall thereof, preferably in a neck region of the first container, opening into a space between the first and second containers. The assembly further includes a connecting device, connected or connectable to the neck portion, wherein the connecting device includes at least one connecting element for connecting to the at least one opening, wherein the connecting element is connected to a source of pressurised gas.

A method of joining polymer components includes additively manufacturing first and second mating features on first and second polymer components such that a mechanical lock is created through undercut geometric features of an adhesive material when the polymer components are joined. Adhesive is added between the mating components to strengthen the joint.

A system and method for producing a disposable undergarment, with the lateral edges of the undergarment bonded by means of an ultrasonic horn. When a blank is formed for an individual undergarment, the lateral edges of opposing edges of the blank will form the seam. When the edges are sealed together, a seam is formed. The individual undergarments may be later separated along the seams.

A plastic laminated structure includes a plate member of plate-shaped fiber-reinforced plastic and a core member of trapezoidal-wave-shaped fiber-reinforced plastic. The plate member includes a thermoplastic resin and reinforcing fibers embedded in the thermoplastic resin. The core member is thermally bonded to the plate member, and includes a thermoplastic resin and reinforcing fibers that is embedded in the thermoplastic resin. A part of or the entire area of a main surface of the plate member includes smooth and rough surfaces. The rough surface has larger roughness than the smooth surface. The smooth and rough surfaces are alternately arranged in stripes.

A method is for manufacturing closing systems for hygiene articles, in particular diaper closing systems. An attachment part (16) is fed to the rear face of a substrate part (18) having protruding closing elements (22) arranged in rows at a predefined distance from each other, and is joined to the substrate part (18) along welding points using an ultrasonic welding process. At least some of the welding points are introduced to extend along weld seam lines (46) between adjoining rows of closing elements (22) and to extend at least partially in parallel to the rows of closing elements (22).

The present disclosure relates to methods and apparatuses for mechanically bonding substrates together. The apparatuses may include a pattern roll including a pattern element protruding radially outward. The pattern element includes a pattern surface and includes one or more channels adjacent the pattern surface. The pattern roll may be positioned adjacent an anvil roll to define a nip between the pattern surface and the anvil roll, wherein the pattern roll is biased toward the anvil roll to define a nip pressure between pattern surface and the anvil roll. As substrates advance between the pattern roll and anvil roll, the substrates are compressed between the anvil roll and the pattern surface to form a discrete bond region between the first and second substrates. As such, during the bonding process, some yielded substrate material flows from under the pattern surface and into the channel to form a channel grommet region.

Disclosed herein is a battery cell configured to have a structure in which an electrode assembly is mounted in a battery case made of a laminate sheet including a resin layer and a metal layer, and the battery case is provided with a sealed portion (an outer edge sealed portion), which is formed at the outer edge of a receiving part, in which the electrode assembly is mounted, by thermal welding in order to seal the battery case, wherein electrode terminals are located at an upper sealed portion, a lower sealed portion, or the upper sealed portion and the lower sealed portion, two or more sealed lines are formed in at least one of side sealed portions, which are adjacent to the upper sealed portion or the lower sealed portion, such that the sealed lines are spaced apart from each other and parallel to each other, the sealed lines are continuously formed from the outer edge end of the upper sealed portion to the outer edge end of the lower sealed portion in the longitudinal direction of the battery case, and the outer edge sealed portion, in which the sealed lines are formed, is bent between the sealed lines at an angle of 30 to 180 degrees.

A method for producing insulating profiles comprises manufacturing a profile body and a first functional element separately, and the profile body and the first functional element are supplied to an ultrasonic welding device, wherein the profile body and the functional element are connected to one another by a material bond by formation of a welded joint. The profile body and the functional element are brought together into a predetermined first cross-sectional geometry during formation of the welded joint and are thereafter guided in this cross-sectional geometry until the plastics material of the welded joint solidifies to such an extent that the profile body and the first functional element are fixed in the predetermined cross-sectional geometry.
