摘要:
A disposable food container formed of sand and a decomposable binder. The disposable food containers are suitable for holding, storing and exposing food to heat in both conventional and microwave ovens. The decomposable binders contain 20 to 40% by weight of a binder selected from the group consisting of starch, grain flours and mixtures thereof, 20 to 30% by weight salt, 1 to 3% by weight oil and water. The containers are covered with a coating to prevent the transmission or absorption of liquids.

A biodegradable package for fast food comprises a heat-molded body of a moldable composition which consists essentially of an admixture of fully biodegradable natural materials comprising flour from edible gramineous plants, crushed gramineous hay, a minor proportion of preserving agents, and a plasticizing agent for providing a starting moldable dough suitable for being molded into the shaped fast food package.

A mixture of boiling water and a gelling agent, such as the polysaccharide agar, are mixed and poured into a mold and allowed to cool and gel. The gelled mixture is then removed from the mold and frozen, after which it is placed in a freeze drier where it is completely sublimated to remove therefrom all moisture. The resultant freeze dried material is extremely light in weight, is biodegradable, and exhibits favorable fire retardant properties.

A method of manufacturing a fluid control device includes extruding a polymer melt into a chamber defined by an outer surface of a support structure and a disintegrable metallic tubular member disposed at the support structure, the polymer melt comprising a high heat polymer and a foaming agent, the high heat polymer having a heat deflection temperature of about 100° C. to about 300° C. measured at 1.82 MPa in accordance with ASTM D648-18; sealing the chamber; and foaming the high heat polymer to produce a porous filtration medium in a compacted shape.
摘要:
A three-dimensional-object forming apparatus generates a three-dimensional object such that from a formation intermediate product obtained by sequentially depositing unit layers each including a curable build material and/or a curable support material, a support made of the support material is removed. The apparatus includes a stage, an ejection unit, a curing unit, and a composite arranger. On the stage, a multilayer structure of the unit layers is placeable. The ejection unit ejects the build and support materials toward an uppermost surface of the multilayer structure while moving relative to the stage. The curing unit cures the build and support materials on the uppermost surface. The composite arranger controls the ejection and curing units, when the support includes a foundation between the object and the stage, to cause the build and support materials to coexist in a lowermost surface region of the object contacting the foundation.

The disclosure describes a thermoforming machine, which can include a horizontal intermittent motion thermoforming machine, and a mold, wherein the mold contains a plurality of pocket forming cavities in a 2-dimensional array. These cavities can each be defined by side walls and a base, and each cavity can be surrounded by a planar surface of the mold on all sides. Further, the cavities can be positioned in the array so as to provide a plurality of continuous strips of uninterrupted planar surface of the mold from a leading to a trailing edge of the mold. These cavities can have rounded bottom corners, formed where the side walls meet the base, and rounded edges, formed where side walls meet an upper surface of the mold. The thermoforming machine can be further configured to be able to draw a web of water-soluble film down into the cavities.

A lens comprises an internal cavity structure formed by dissolution of a soluble insert material. The internal soluble material may dissolve through a body of a lens such as a contact lens in order to form the cavity within the contact lens. The cavity within the lens can be shaped in many ways, and corresponds to the shape of the dissolved material, such that many internal cavity shapes can be readily fabricated within the contact lens. The insert can be placed in a mold with a pre-polymer material, and the pre-polymer material cured with the insert placed in the mold to form the lens body. The polymerized polymer may comprise a low expansion polymer in order to inhibit expansion of the lens when hydrated. The polymer may comprise a hydrogel when hydrated. The soft contact lens material comprises a sufficient amount of cross-linking to provide structure to the lens and shape the cavity.

Systems and methods for making a custom sleep apnea mask or other wearable article are disclosed. The sleep apnea system comprises a face mask, a headband integrally connected to the face mask, and at least one air duct configured to direct air from the CPAP machine to nasal tubes. The face mask preferably comprises: an inner surface having the same shape as the user's face; an upper surface configured to sit at a first predetermined distance between the user's nose and eyes; and an outer surface configured to extend a second predetermined distance from the inner surface. Nearly shape and position of substantially all the surfaces of the mask are configured based on the shape and or location of facial features, resulting in a highly customized mask optimized for each individual patient.
摘要:
A plastic film is produced by blending a polymer with particles encapsulating an oxidizing agent, such as hydrogen peroxide. Optionally, an “oxodegradable” and/or “oxo biodegradable” additive that promotes degradation of the polymer in the presence of oxygen may be blended into the plastic film. The presence of the oxidizing agent within the plastic film ensures degradation of an article of manufacture, e.g., a plastic bag, when it is disposed of in an anaerobic environment, such as a landfill. In some embodiments, the particles are microcapsules and/or nanocapsules each having a polymer shell encapsulating a core that includes the oxidizing agent. In some embodiments, the particles are microparticles and/or nanoparticles each having a matrix in which the oxidizing agent is encapsulated.
