Compositions and methods for manufacturing starch-based compositions

Compositions and methods for manufacturing sheets having a starch-bound matrix reinforced with fibers and optionally including an inorganic mineral filler. Suitable mixtures for forming the sheets are prepared by mixing together water, unmodified and ungelatinized starch granules, an auxiliary water-dispersible organic polymer, fibers, and optionally an inorganic mineral filler in the correct proportions to form a sheet having desired properties. The mixtures are formed into sheets by passing them between one or more sets of heated rollers to form green sheets. The heated rollers cause the auxiliary polymer to form a skin on the outer surfaces of the sheet that prevents the starch granules from causing the sheet to adhere to the rollers upon gelation of the starch. The green sheets are passed between heated rollers to gelatinize the starch granules, and then to dry the sheet by removing a substantial portion of the water by evaporation. The starch and auxiliary polymer form the binding matrix of the sheets with the fibers and optional inorganic filler dispersed throughout the binding matrix. The starch-bound sheets can be cut, rolled, pressed, scored, perforated, folded, and glued to fashion articles from the sheets much like paper or paperboard. The sheets are particularly useful in the mass production of containers, such as food and beverage containers.

Resealable vial with connector assembly having a membrane and pusher

InactiveUS6168037B1Prevent inadvertent withdrawalCapsClosure using stoppersElastomerBottle
A resealable vial featuring a connector assembly having a membrane and a pusher for selectively opening or sealing the fluid passageway between the bottle and the connector end of a luer hub. The connector assembly includes a body disposed on said bottle, and means for communicating fluid such as a luer connector hub which may be separately provided with the body or formed integrally therewith. The luer connector hub features a connector end open for access by medical delivery instrument, and an opposed end which is disposed for fluid communication with a recess defined by the body. The body defines a recess having a fluid path with the open top of the bottle. A membrane, preferably formed from an elastomeric material, is secured across both the recess and the open top of the bottle, and may be retained between the top surface of the bottle and the body. The membrane preferably includes a central area sealing the recess from the open top of the bottle, with one or more fluid openings defined on a portion of the membrane outside of the central area. A pusher is located in the recess. A force exerted on the pusher deflects the membrane towards the interior of the vial, urging the membrane and fluid openings away from the body to open the fluid path between the bottle and the recess. The pusher may be structured to include one or more fluid pathways so as to facilitate fluid flow through the recess. A sealing rib may be provided around the portion of the periphery of the recess to enhance sealing contact between the central area of the membrane and the recess.

Container closure with overlying needle penetrable and thermally resealable portion and underlying portion compatible with fat containing liquid product, and related method

InactiveUS20060231519A1Avoiding seal integrity problemGood product containmentCapsLiquid fillingLiquid productFormulary
A container and method are provided for storing fat containing liquid products, such as infant or baby formula, or other milk-based products. The container includes a body defining a storage chamber for receiving the aseptic fat containing liquid product, and a first aperture in fluid communication with the storage chamber. The body does not leach more than a predetermined amount of leachables into the fat containing liquid product and does not undesirably alter a taste profile of the fat containing liquid product. A container closure assembly includes a stopper receivable within the first aperture for hermetically sealing the storage chamber. The stopper includes a first material portion defining an internal surface in fluid communication with the storage chamber forming at least most of the surface area of the container closure that can contact any fat containing liquid product within the storage chamber and that does not leach more than a predetermined amount of leachables into the fat containing liquid product or undesirably alter a taste profile of the fat containing liquid product. A second material portion of the stopper either (i) overlies the first material portion and cannot contact any product within the storage chamber, or (ii) forms a substantially lesser surface area of the container closure that can contact any product within the storage chamber in comparison to the first material portion. The second material portion is needle penetrable for filling the storage chamber with product, and a resulting needle aperture formed in the second material portion is thermally resealable such as by the application of laser energy to seal the product within the storage chamber. A sealing portion of the container closure is engageable with the body prior to needle filling the storage chamber to thereby form a substantially dry hermetic seal between the container closure and body.

Tube rack

A tube rack comprises a base having an array of vertical openings extending therebetween, the openings being configured and dimensioned to receive a plurality of tubes, with the upper ends of the tubes being accessible at the top surface. The base includes base sidewalls that each include a co-axial trunnion extending from the associated sidewall. The tube rack also includes a rotatable and removable cover having a front wall, a back wall and first and second sidewalls, wherein the first and second side walls each include an associated notch open on a bottom surface thereof to allow the cover to be lowered onto the base, such that each of the notches rests on its associated trunnion and may be (i) vertically raised from its closed position on the trunnions and (ii) rotated about the trunnions from its closed position to allow access to the array of openings, wherein each of the notches includes a trunnion travel surface and a ledge surface and the ledge surface engages its associated trunnion to limit rotation of the cover beyond its full cover position. Each of the openings comprises a plurality of support pads positioned within the opening to vertically support the tube within its associated opening. Each of the pads includes a chamfered concave surface that supportably engages the tube, while providing flow paths through which air may pass through the openings adjacent to the tube.
