摘要:
An apparatus and method for creating a vacuum-sealed package comprising the placement of the item to be vacuum packed in a container; sealing the container, placing a portion of the container in contact with a sealable chamber; sealing the chamber, creating holes in the container, evacuating the desired amount of air from the container and creating a seal between the interior of the container and the holes.

First and second pipes having at least two concentric layers of thermoplastic material are joined to form a pipe assembly. A non-planar mating surface is prepared on the end of each pipe. The pipes are brought into abutment at the mating surfaces to form a joining zone. Each of the mating surfaces is heated and then cooled under compression to solidify the joining zone, thereby forming a weld. Preferably separate heating processes are used to melt and join the separate layers, thereby substantially eliminating the intermingling of the layers, which may be chemically incompatible. A strong, durable joint is effected in a simple and reliable manner. Optionally, a melt flow insert is disposed between the pipes being joined to provide physical separation between the volumes of the different layers that are melted during the formation of the joint.

A stitchless seam between a first panel (4) having a functional layer and a second panel (4) having a functional layer is provided. The seam system is formed via a discontinuos fused stitchless seam (6), which connetcts a first panel to a second panel. A reinforcement (5) may be used to strengthen the discontinuos fused stitchless seam connecting the first panel to the second panel, allowing formation of a liquid- impervious stitchless seam system. A method for forming the system is also provided.

A game ball, such as a soccer ball, having a cover comprised of one or more cover panel blanks and one or more reinforcement material blanks, is provided. The cover panel blanks and reinforcement materia! blanks are heat bonded together so that the free edges and interior panel boundaries of the cover panel blanks are al igned with the reinforcement material blanks.

An intravenous delivery system (100) may have a liquid source (102) containing a liquid (122), tubing (106), and an anti-run-dry membrane (136, 320, 420, 720) positioned such that the liquid (122), flowing form the liquid source (102) to the tubing (106), passes through the anti-run-dry membrane (136, 320, 420, 720). The anti-run-dry membrane (136, 320, 420, 720) may be positioned within an exterior wall (133, 310, 410, 710, 1110) of a drip unit (134, 300, 400, 700, 1100), and may have a weld surface (346, 446, 746) secured to a seat (334, 434, 734, 1134) of the exterior wall (133, 310, 410, 710, 1110) via application of compression to press the weld surface (346, 446, 746) against the seat (334, 434, 734, 1134), and application of coherent light (352) or vibration. In response to application of the coherent light (352) or vibration, localized melting may occur, causing the weld surface (346, 446, 746) to adhere to the seat (334, 434, 734, 1134). The anti-run-dry membrane (136, 320, 420, 720) may be modified to have a melting point close to that of the seat (334, 434, 734, 1134). Ultrasonic or laser welding may be applied in a manner that causes portions of the seat (334, 434, 734, 1134) to melt and flow into pores (138) of the weld surface (346, 446, 746).
