  • Patent number: 12215032
    Abstract: A far infrared (FIR)-emitting composition includes a first polymer component and a silicon dioxide composite particle which is prepared by subjecting a tetraalkoxysilane and a compound represented by Formula (A) to hydrolysis and condensation polymerization: Y—Si(ORa)3??(A), wherein each Ra independently represents a C1-4 alkyl group or a C1-4 alkanoyl group, Y represents X—R1—, a non-substituted C1-18 linear alkyl group or a non-substituted C3-18 branched alkyl group, and X and R1 are defined as set forth in the Specification and Claims. A FIR-emitting fiber including the FIR-emitting composition is also disclosed.

  • Patent number: 11795058
    Abstract: The present invention relates to a silicon dioxide composite particle with far-infrared radioactivity, which is formed by the hydrolysis, condensation and polymerization of an organic silane precursor having the structure of the formula (I) with a tetra-alkoxysilane. The high stability of organic silane precursor compounds and the low biotoxicity of silicon dioxide composite particles make the present far-infrared radioactive silicon dioxide composite particles of great potential for extensive use in related bio-products.

  • Patent number: 11406566
    Abstract: A pill cutter has a base, a clamping assembly, a connecting unit, a cover, and a cutting assembly. The clamping assembly has two first clamping units moveably mounted on the base. The connecting unit has a base end moveably mounted on the base and a cover end pivotally mounted on the cover. The cutting assembly has a pressing unit moveably mounted on the cover and a blade securely mounted on the pressing unit. When the cover is opened, the connecting unit moves along with the cover and pulls the two first clamping units away from each other. When the cover is closed, the two first clamping units move toward each other by springs to stably clamp a pill in any shape or size. Therefore, a user can simply press the pressing unit to move the blade to safely cut the clamped pill.

  • Patent number: 11299504
    Abstract: A process for preparing a triazine-based precursor for producing a micro-particulate complex containing a far infrared-emissive silica particle comprises steps of: a) subjecting 2-4-6-trichloro-1,3,5-triazine and a first nucleophilic compound to a displacement reaction in the presence of a first solvent at a first temperature range to form an intermediate; and b) subjecting the intermediate and a second nucleophilic compound to a further displacement reaction in the presence of a second solvent at a second temperature range higher than the first temperature range.

  • Patent number: 11166873
    Abstract: A pill box has a case holder and multiple pill cases. The case holder is divided into multiple compartments by multiple crosswise partitions, a rear panel and a bottom panel. The pill cases are fitted in the compartments of the case holder. Each pill case is able to pivot relative to the case holder between a close position and an open position. When intending to get pills that are in the pill box, a user can rotate one of the pill cases to the open position. Thus, the pill case protrudes forwardly from the case holder. Accordingly, the pills are able to be precisely poured onto the user's hand.

  • Patent number: 11123263
    Abstract: A pill box has a container having a compartment frame, multiple front covers pivotally mounted to the container and selectively covering a front side of the container, and a rear lid. The rear lid is detachably mounted on a rear side of the container and has a main covering panel having an outer peripheral frame and multiple inner annular frames, and two side locking panels. With the compartment frame of the container protruding in a groove formed between the outer peripheral frame and the inner peripheral frames of the main covering panel when the main covering panel covers the rear side of the container, the rear side of the container can be tightly sealed by the rear lid easily, so as to prevent dust and moisture from entering the pill box. Accordingly, pills can be properly reserved in the pill box of the present application.

  • Publication number: 20210177698
    Abstract: A pill container has at least one pair of compartment units. Each pair of compartment units has two compartment units and a connection portion being hollow and mounted between the compartment units to connect the two compartment units with each other. Each compartment unit has a compartment, a locking button, a lid, and a resilient pushing bar. The compartment is hollow and has a front wall and a rear wall connected with the connection portion. The locking button is formed on the front wall of the compartment. The lid is pivotally connected with the rear wall of the compartment to selectively close the compartment, is engaged detachably with the locking button, and has an inner surface facing the compartment. The resilient pushing bar is mounted in the connection portion, extends over the rear wall of the compartment, and abuts against the inner surface of the lid.
