An aerosol container suitable for use as an aerosol dispenser. The aerosol container includes at least a valve and product delivery device joined to an outer container. The valve and product delivery device have respective annular welds or other seals joining the valve and product delivery to the outer container. The welds, or other seals may be concentric, with one circumscribing the other, in the same plane or different planes. Suitable product delivery devices include bags and dip tubes.

Systems and methods are presented herein for a method of attaching a strip to a housing. An internal support member is inserted into a collapsible housing, such that it is arranged along a longitudinal axis of an inner surface of the collapsible housing. An outer support member is arranged along an outer surface the collapsible housing opposite the internal support member. A strip is positioned along the outer surface using the outer support member and the internal support member. Then the strip is permanently welded to the outer surface using a welding element. Welding is performed by a welding element located in one (or both) of the internal support member or the outer support member.

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.

Provided is a laser welded body which can be integrated through a laser-welding step without undergoing complicated steps even through use of the same or difference resin members each other, which has excellent welding strength between the resin members, which maintains the characteristics of a resin contained in the resin member and which exhibits the high welding strength by improving meltability of the resin members yet under a laser-welding condition of a medium and high scan speed. A laser welded body comprises a resin member(s) which contains a thermoplastic resin and nigrosine sulfate having a sulfate ion concentration of 0.3 to 5.0% by mass and has an absorbance a of 0.09 to 0.9, an adjoined part where the resin member(s) is overlapped and/or butted, and at least a part of the adjoined part is laser-welded.

An ultrasonic welding device includes a support device configured to support a work piece along a predetermined conveyance surface; a welding machine including an oscillator for generating a high-frequency electric signal, a transducer for converting the high-frequency electric signal to a mechanical vibration, and a horn to which the mechanical vibration is transmitted, the horn being disposed to face a part to be welded of a work piece supported along the conveyance surface, and the mechanical vibration being imparted via the horn to the part to be welded, whereby the part to be welded is welded; a detector for detecting an abnormality in the part to be welded, the detector being disposed upstream in the conveyance direction of the work piece than the support device; and a protective device for prohibiting the welding machine from welding the part to be welded in which an abnormality is detected by the detector.

A resin joint 20 includes an outer cylinder 21 molded by a resin material capable of transmitting laser light and an inner cylinder 22 disposed facing the inner peripheral surface of the outer cylinder 21. An annular protrusion 22b that protrudes in the radial direction and extends in the circumferential direction is formed on the inner peripheral surface of the outer cylinder 21 or the outer peripheral surface of the inner cylinder 22. The axial end of the resin tube 10 is inserted into an annular space 30 and is deformed in the radial direction following the annular protrusion 22b, and a region deformed in the radial direction has a surface that is in contact with the inner peripheral surface of the outer cylinder 21. The inner peripheral surface of the outer cylinder 21 and the outer peripheral surface of the resin tube 10 are laser-welded.

A sealing device generally includes a rotatable support cylinder having an outer, circumferential surface and a heating element disposed about such surface and secured thereto such that the heating element rotates therewith. The heating element is coiled about the outer surface of the cylinder in the form of an overlapping helical pattern. Juxtaposed film plies may be sealed together by bringing the sealing device into rotational contact with the juxtaposed film plies and heating the heating element to a temperature sufficient to cause the film plies to seal together.

The present disclosure generally relates to devices and methods for furniture protection. More particularly, the present disclosure relates to foam-film sheets configured to protect furniture from damage. An exemplary foam-film sheet as disclosed herein includes a sheet of foam material having a first lateral edge and a second lateral edge; a sheet of film material having a first lateral edge and a second lateral edge; a first seal between a portion of the foam material proximate its first lateral edge and a portion of the film material proximate its first lateral edge; and a second seal between a portion of the foam material proximate its second lateral edge and a portion of the film material proximate its second lateral edge, wherein the film and foam are substantially unsealed along the entire transverse width between the first and second sealed portions near the lateral edges of the foam material.

An apparatus for vacuumizing and sealing a package includes a plurality of platens and vacuum chambers, each chamber adapted to mate with a dedicated one of the platens; a conveying system for conveying the platens and chambers along a generally angular path having a single axis of rotation; an automated loading assembly having a linear component and configured to load a package onto each of the platens; an automated unloading assembly having a linear portion and configured to unload a vacuumized, sealed package from each loaded platen onto an outfeed conveyor; and a vacuumizing/sealing system configured to cause relative movement of each chamber/platen pair, along a portion of the angular path, to form therebetween an air-tight enclosure accommodating the package and effect vacuumization and sealing of the package.

A new method for fully automatically manufacturing a fluid container with a pressure unit is described, which pressure unit is mounted in a fluid container. In a station the high-pressure container of the pressure unit is mounted with the closure and the bottom part and is clamped at the upper and lower ends by clamping means and is rotated by rotating means associated with the clamping means. The rotating pressure unit is welded by first laser means and by second laser means, whereas the laser beam of the first laser means being directed to a first joint area of the bottom part of the pressure unit with the container, and the laser beam of the second laser means being directed to a second joint area of the bottom part of the pressure unit with the container, which first and second joint area are separated at a distance to each other.
