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.

An ultrasonic sealing tool including an anvil with a sealing surface, a horn with a sealing surface facing the sealing surface of the anvil, the sealing surface of the anvil including a plurality of beads including a first bead having a first height and at least one second bead having a second height, the second height being less than the first height, the ultrasonic sealing tool delivering ultrasonic vibrations via at least one of the anvil and the horn to create a closure seal in a work piece positioned between the anvil and the horn, the closure seal including a first seal created by the first bead and at least one second seal created by the at least one second bead, the first seal having a weld depth greater than a weld depth of the at least one second seal.

A method of riveting using a plastically deformable plastic rivet is provided. The method includes positioning the plastic rivet in front of the rivet on a component, of a motor vehicle, and deforming the rivet by a riveting die by applying a riveting force, such that a rivet holds the component wherein the rivet is with a rivet dynamometer and the riveting force is measured and a rivet is set with a predetermined breaking point.

A heat seal device includes at least two primary biasing members and a secondary biasing member. These biasing members are located between a slider and a first heat seal member to bias the first heat seal member towards a second heat seal member when bag components are sandwiched by the first and second heat seal members. The primary biasing members are arranged in a straight line in the first horizontal direction. The secondary biasing member is arranged offset from the primary biasing members in a second horizontal direction perpendicular to the first horizontal direction. The heat seal device is configured to allow adjustment of biasing force applied to the first heat seal member by the secondary biasing member.

A sonotrode and anvil are adapted for ultrasonic welding of work pieces, to produce a narrower weld region that exhibits greater durability, permitting use of less material per package. The horn-to-anvil contact is through a plurality of energy directors arranged into a three-dimensional grid pattern to be capable of distributed vibration-transmissive contact. The energy directors include a series of plateau surfaces regularly spaced apart in a first direction, and in a second direction that is orthogonal to the first direction, to form the grid pattern. The energy directors of the horn are configured to interlock with the energy directors of the anvil. The rectangular-shaped plateaus are spaced apart by angled side-surfaces that form valleys. A stepped transition to a corresponding region of reduced height for the energy directors of the sonotrode and anvil may form a cosmetic seal region with a lesser integrity, in addition to the main barrier seal.

To achieve universal welding of thermoplastic workpiece parts with simple equipment, an infrared light transmission welding method is disclosed in which simple polychromatic, incoherent infrared light is generated by a simple infrared light source and is directed through a first workpiece part to a weld point for the purposes of connection to a second workpiece part. In particular, the infrared light is directed through a transparent bracing element.

A product detection system includes a first frame piece configured to be coupled to a first sealing jaw of a sealing machine, a second frame piece configured to be coupled to a second sealing jaw of the sealing machine, a first detector bar slidably coupled to the first frame piece, a second detector bar slidably coupled to the second frame piece, a first linear actuator coupled to the first detector bar to move the first detector bar, and a second linear actuator coupled to the second detector bar to move the second detector bar. An encoder is coupled to the second detector bar to detect movement of the second detector bar. The first and second linear actuators are configured to move the first and second detector bars toward one another.

In accordance with the present inventive concept, there is provided a method for sealing a flexible package of collapsible type. The method comprises providing a first seal extending transverse a filling channel of the flexible package and providing a second seal extending transverse a filling channel of the flexible package. Said second seal overlaps said first seal such that a combined seal is provided comprising a top portion formed solely by a first sealing unit, an intermediate portion formed by the first and a second sealing unit, and a bottom portion formed solely by the second sealing unit. The method further comprises setting operating parameters comprising a time parameter, a temperature parameter and a pressure parameter for providing said first seal and for providing said second seal such that a sealing characteristic below a threshold value is obtained in said top portion and said bottom portion and such that a sealing characteristic equal to or above the threshold value is obtained in said intermediate portion.

The present invention relates to a counter-tool for an ultrasonic welding machine, wherein the counter-tool comprises two separate sealing surfaces which are intended to come into contact with a material to be processed, characterized in that the counter-tool is formed in two parts, wherein the two parts of the counter-tool are movable relative to one another, and each of the two parts comprises one of the two sealing surfaces.

Embodiments related to juicing systems including juicers for extracting juice from food matter contained within juicer cartridges are described.
