  • Patent number: 7955671
    Abstract: A domed lid 12 for a food container 10 is configured for ease of engagement and removal from a container base 14. The lid characteristically includes: (a) a dome portion 16 with a top wall 24 and a sidewall 26; (b) a flange portion 28 extending outwardly away from a lower portion of the sidewall; and (c) a tab portion 30 extending outwardly from the flange.

  • Patent number: 7955670
    Abstract: A method of making a texture-coated and/or insulation coated container from a flat paperboard blank in which a heat-hardenable liquid polymeric binder texturizing and/or insulating agent coating mixture is applied to one surface of the blank in a pattern of covered and open areas. This coating mixture is subjected to heat to cure the polymeric binder and expand the texturizing and/or insulating agent, optionally treated with moisture, and optionally heated to form the blank into the shape of a container, and the container produced by this method. The containers such as cups, plates, etc., are useful in food service. These containers have a coefficient of static friction which is about 0.2 to 2.0 and over and a kinetic coefficient of friction which is about 0.22 to 1.5.

  • Patent number: 7938294
    Abstract: A large capacity napkin dispenser for in counter mounting includes: (a) an elongate housing having a generally rectangular cross-section for receiving a stack of napkins; (b) a faceplate with a dispensing aperture, the faceplate being hinged to the housing so as to be movable between an open position for re-loading and a closed position for dispensing; (c) a movable support member mounted in the housing; (d) biasing means for urging the movable support toward the faceplate so that the stack of napkins is advanced to the aperture as it is depleted; and (e) sequestered means for locking the faceplate in the closed position. The locking means includes release means located adjacent the inner surface of the faceplate such that when the faceplate is in the closed position the release means is concealed in the interior of the dispenser, thereby eliminating the need for a key.

  • Patent number: 7045559
    Abstract: A composition providing electrically conductive adhesive hydrogels suitable for use as skin contact adhesives and, particularly, suitable for use as an electrical interface for disposable medical devices. The present hydrogels provide for reduced skin irritation and/or malodor properties, hydrate a subject's skin, readily wet around a subject's skin surface hair, and protect against burning of a subject upon or due to electrical stimulation through the hydrogel. These hydrogels generally include a monomer, a first initiator, a solubilizer, and a cross-linking agent. The present hydrogels also desirably include a buffer system to help prevent discoloration of the hydrogels and/or hydrolysis of the hydrogels as well as to improve shelf-life. Other additives such as conductivity enhancers, pharmaceuticals, humectants, plasticizers, skin health agents, etc. may be added to the present hydrogels either before or after curing.

  • Patent number: 6777056
    Abstract: Composite nonwoven webs are provided having two distinct regions extending adjacent one another in the machine direction of the web; the first region is formed from first continuous filaments and the second region is formed from second continuous filaments. The interface of the first and second region is formed from a mixture the first and second continuous filaments in a confluent relationship with one another and such that the two distinct regions form a unitary nonwoven web. The respective first and second regions can have distinct physical attributes as a result of utilizing first and second filaments which are different from one another. The first and second continuous filaments can vary with respect to average fiber denier, cross-sectional shape, cross-sectional configuration, polymer composition, crimp level, and additive composition.

  • Patent number: 6727196
    Abstract: The present invention relates to a composite material including a substrate with a first and a second layer, and a surfactant. The surfactant is applied to the first layer of the substrate. The surfactant acts to lower the surface tension of a fluid which contacts the first layer of the substrate such that the fluid is allowed or more readily enabled to pass through the first layer of the substrate, but such that the surfactant does not substantially adversely effect the absorption capacity or wicking height of the second layer of the substrate, as the second layer of the substrate substantially inactivates the surfactant upon contact or interaction therewith.

  • Patent number: 6610383
    Abstract: The present invention is directed to a necked laminate and a process for making the laminate. The necked laminate is formed from sheet layers of at least one non-elastic neckable material laminated to at least one non-elastic film defining a longitudinal and transverse dimension wherein the laminate is extensible and retractable in at least one dimension without significantly reducing the breathability and/or liquid barrier properties of the film layer. This laminate extensibility and retractability is the result of striated rugosities in, for instance, the longitudinal dimension of the film layer which enables the necked laminate to have an amount of extensibility and retractability in the transverse dimension. The laminate is made by first partially stretching the non-elastic film layer, attaching a non-elastic neckable layer to form a laminate and then stretching the laminate to neck the laminate and stretch the film to its desired fully stretched configuration.

  • Patent number: H2086
    Abstract: The present invention provides a filter media comprising (a) a nonwoven composite material comprising a stabilized mixture of thermoplastic microfibers and at least about 50%, by weight, of a secondary fibrous material such as pulp or polymeric staple fibers; (b) a first outer nonwoven web comprising a substantially uniform nonwoven web of autogenously bonded multicomponent fibers; and (c) a second outer nonwoven web wherein the nonwoven composite material is positioned between the first outer nonwoven web and second outer nonwoven web. The filter material is well suited to filtering liquid borne particulate matter ranging in size from 5&mgr; to about 25&mgr;.
