Abstract: An apparatus for joining a first film portion and a second film portion together along a seal line. The apparatus includes a horn and anvil. The anvil is positioned close to the horn. The horn or anvil has a face that is rotatable about a rotation axis. The face has a raised profile, and a height thereof has a dimension corresponding to 50% to 150% of a thickness of the first film portion or the second film portion. The face is positioned such that the raised profile extends along the circumference such that continuous running contact is provided between the raised profile and the other of the one of the horn or the anvil when rotated about the rotation axis, to form the seal line without any external structure to control a distance between the horn/anvil. A tapered bonding profile, a traction pattern, and a cut-and-seal feature are also disclosed.

The third pair of adjacent bonds is located between the first pair of adjacent bonds and the second pair of adjacent bonds.

Abstract: An apparatus for joining a first film portion and a second film portion together along a seal line. The apparatus includes a horn and an anvil. The anvil is positionable in close proximity to the horn. Either the horn or the anvil has a face with a width dimension and a circumference and is rotatable about a rotation axis. The face has a raised profile, and a height of the raised profile has a dimension corresponding to 50% to 150% of a thickness of the first film portion or the second film portion. The face is positioned such that the raised profile extends along the circumference such that continuous running contact is provided between the raised profile and the other of the one of the horn or the anvil when rotated about the rotation axis, to form the seal line without any external structure to control a distance between the horn and the anvil.

Abstract: An apparatus for fabricating an elastic nonwoven material generally includes a rotary ultrasonic horn and a rotary anvil positionable in close proximity to the ultrasonic horn. The anvil has a face with a width and a circumferential axis. The face has a plurality of ridges each of which defines a plurality of interspaced lands and notches.

Abstract: A face covering includes layers of nonwoven material and at least one elastic element. The layers of nonwoven material cooperatively define a first opening, a second opening, and a filtration area of the face covering. The filtration area is arranged to allow airflow through the face covering and remove particulates from the airflow. The first opening and the second opening are sized to receive a head of a wearer. The at least one elastic element is secured to the layers of nonwoven material. The face covering is sized such that, when the face covering is positioned on the head of the wearer, the at least one elastic element provides a seal against the wearer and the layers of nonwoven material provide a loose fit on the wearer.

Abstract: A package having a tearable seal is disclosed, along with a method of opening the package. The package is capable of housing a product and includes a front wall, a back wall, a first side, a second side, a bottom and a top, and has a void area formed between the front and back walls which can house the product. The package is completely sealed after the product has been inserted into the void area. The package has a tearable seal formed in both the front and back walls. The tearable seal has an end conterminuous with the first side. The package also has a second seal formed in both the front and back walls which is positioned inward of the first and second sides and which is located between the tearable seal and the top. The second seal has a patterned field of bonds. The tearable seal requires less force to break than does the second seal. A method of opening the package is also taught.

Abstract: Delivery systems for incorporating functional compounds into substrates for use in various consumer products are disclosed.

Abstract: In a system and process for ultrasonically treating a liquid and delivering the liquid as a spray of liquid droplets, liquid is directed to flow along a flow path over a first ultrasonic waveguide, with the first ultrasonic waveguide having at least one agitating member extending outward therefrom and into the flow path. The first ultrasonic waveguide and agitating member(s) are excited to agitate the liquid as the liquid flows along the flow path. The liquid is further directed to flow along the flow path over a second waveguide, with the second waveguide having a terminal end adjacent an exit of the flow path. The second ultrasonic waveguide is ultrasonically excited at least at its terminal end to ultrasonically energize the liquid just prior to the liquid exiting the flow path such that the liquid exits the flow path as a spray of liquid droplets.

Abstract: A liquid treatment system has a housing defining an interior space. The housing has an inlet port for receiving liquid into the interior space of the housing and an outlet port for allowing liquid to exit the interior space of the housing. The outlet port is spaced from the inlet port so that liquid flows through the interior space of the housing from the inlet port to the outlet port. An ultrasonic waveguide assembly is disposed within the interior space of the housing and includes an ultrasonic horn disposed at least in part intermediate the inlet port and the outlet port of the housing. The ultrasonic horn is operable at an ultrasonic frequency to ultrasonically energize liquid flowing within the housing. An ultraviolet light source emits ultraviolet light into the interior space of the housing to treat liquid flowing therein.

Abstract: In a method of ultrasonically treating a substance disposed within a container an ultrasonic horn is positioned within the container with at least a portion of the horn submerged in the substance. The horn is ultrasonically excited to thereby ultrasonically energize the substance. An agitating member is rotated within the substance while the ultrasonic horn is excited to agitate the substance as the substance is ultrasonically energized.
