Abstract: The present invention provides a flexible bag comprising at least one sheet of flexible sheet material assembled to form a semi-enclosed container having an opening defined by a periphery. The opening defines an opening plane, and bag is expandable in response to forces exerted by contents within the bag to provide an increase in volume of the bag such that said the accommodates the contents placed therein.

Abstract: A food storage and preparation bag at least one sheet of flexible sheet material assembled to form a semi-enclosed container having an opening defined by a periphery and a closure for sealing the opening to convert the semi-enclosed container to a closed container. The opening defines an opening plane and the sheet material includes a first region and a second region being comprised of the same material composition. The first region undergoes a substantially molecular-level deformation and the second region initially undergoes a substantially geometric deformation when the sheet material is subjected to an applied elongation along at least one axis. The first region and the second region are visually distinct from one another, wherein the second region includes a plurality of raised rib-like elements and the first region is substantially free of rib-like elements.

Abstract: An absorbent article, such as a diaper, sanitary napkin, adult incontinent device, and the like having meltblown components is provided. The absorbent articles preferably comprises a liquid pervious thermoplastic apertured film topsheet, a liquid impervious backsheet, an absorbent core, and a fibrous acquisition web of spunlaced nonwoven fibers. The absorbent core is positioned between the topsheet and backsheet which are joined at least about a portion of the periphery of the absorbent article and the topsheet is fused to the acquisition web at discrete points of attachment. The acquisition web is positioned between the topsheet and the absorbent core.

Abstract: Disclosed is an absorbent article having a liquid pervious topsheet, a liquid impervious backsheet joined to the topsheet, and an absorbent core positioned therebetween, in which the absorbent core is enveloped by a primary core integrity layer comprising a continuous mesh of meltblown material which is joined to the topsheet. The primary core integrity layer is particularly useful for improving the wet integrity of absorbent cores comprising an upper acquisition/distribution layer and a lower storage layer.

Abstract: A packing gland is positioned down within an oil well hole and is held in place by elastomeric sealing and locking devices which are actuated from above the hole through a torque tube. Rotation of the torque tube in one direction lowers the tube axially relative to the elastomers and causes them to expand radially thus locking and sealing the stuffing gland assembly in the well head equipment at a depth of about 100 feet below the ground surface. Counter rotation of the torque tube allows the elastomers to retract radially thus releasing the stuffing gland assembly. Once the stuffing gland assembly is released, a union joint assembly is moved downward relative to the stuffing gland assembly and a unique spring ring slides over a cylindrical boss on the packing gland assembly to couple the union joint assembly with the packing gland assembly. The packing gland assembly then is raised above the ground surface simultaneously with lifting the polish rod from the hole.

Abstract: A fluid pervious web suitable for use as a topsheet on an absorbent article is disclosed. The topsheet includes a fibrous and apertured, three-dimensional, macroscopically expanded, plastic web. The fibrous and apertured, three-dimensional, macroscopically expanded, plastic web permits bodily fluids to penetrate while providing an improved, less plastic-like feel and visual aesthetics.
