STERILIZABLE DUAL COMPARTMENT POUCH

Resumen de: US2025033848A1

A pouch for holding a medical device. A base layer has a base periphery, a base back end and opposing base outer edges. A breathable first web is on the base layer and adapted to permit a sterilization gas to pass therethrough. A non-breathable middle film is adhered to the first web. A breathable second web is attached to the middle film, and a non-breathable top layer is over the base layer, thereby the pouch includes five layers. A primary seal adheres the base layer and the top layer. Then a secondary seal adheres the middle film and the second web to the base layer. The secondary seal is coextensive with the primary seal but then extends a partial width of the primary seal to thereby form a setback, wherein the setback allows the first web, the middle film and the second web to be formed in a single sealing step.

HERMETIC LASER-WELDED ENCLOSURE

Resumen de: US2025033853A1

A hermetically sealed enclosure is shown, comprising at least a first substrate and a second substrate, a function zone that is circumferentially enclosed in the enclosure, wherein the second substrate is transparent at least in part and/or at least for a bandwidth of wavelengths, at least one laser weld line to hermetically weld the substrates of the enclosure with each other and/or to hermetically seal the function zone, and at least one reduction zone for reducing an amount of molecules in the function zone.

Resumen de: EP4497492A1

There is provided an oxygen scavenger composition comprising iron, a metal salt, and water, wherein the content of water per unit surface area of the iron present on the surface of the iron, the content of water present on the surface of the iron (g) / {the content of the iron (g) × the specific surface area of the iron (m²/g)}, is more than 2.00 g/m² and 3.50 g/m² or less.

Radically Polymerizable Materials For The Production Of Dental Molding With Little Discoloration

Resumen de: US2025002631A1

A free radical polymerization initiator system having at least one monoacylphosphine oxide of formula (I)in whichR1, R2, R3 independently of one another are each H, or a linear or branched C1-C10 alkyl radical or OR6,R4 is a linear or branched C1-C10 alkyl radical, C1-C10 alkoxy radical, cyclohexyl radical or a phenyl, methylphenyl or mesityl radical,R5 is a linear or branched C1-C10 alkyl radical,R6 is a linear or branched C1-C6 alkyl radical, andn is 0, 1, 2 or 3,and at least one phenolic inhibitor, wherein the molar ratio of inhibitor to photoinitiator is in a range from 0.002 to 0.9. The initiator system is particularly suitable for the photopolymerization of radically polymerizable compositions containing urethane group-containing monomers and for the production of dental moldings with low discoloration.

METHOD FOR DEHYDRATING AN ITEM UTILIZING A MOISTURE REMOVING BAG

Resumen de: US2025002241A1

A method for dehydrating an object includes forming a container from a moisture wicking, air impermeable, polyvinyl alcohol sheet. The sheet is folded upon itself to form a folded structure having layer of the sheet in facing relationship with a second layer of the sheet. The first layer is sealed to the second layer along the length of a first open edge. The first layer is sealed to the second layer along the length of a second open edge; the opposed to the first open edge forming an open-ended container at a remaining open edge. An object to be dehydrated is placed in the container and the first layer is sealed to the second layer along the remaining layer.
