A beverage holding device comprising a container and a removably engageable lid. The container includes a partition extending between opposing sides of the sidewall of the container to define a plurality of separated cavities. The partition includes an edge surface forming an interior seal against a lower surface of the lid upon an engagement of the lid with the container for maintaining the plurality of cavities fluidly separated. A plurality of apertures in offset elevated positions above an upper surface of the lid are provided, with each communicating with a respective one of the plurality of cavities. The elevated and offset apertures provide a respective relief area to accommodate a projecting nose of a user during an engagement of the user's mouth with a respective aperture while tipping the container.

Fluorochemical benzotriazoles

A pressure-sensitive adhesive layer is crosslinked between carboxyl groups along one surface by polyvalent cations, thus making that surface substantially tack-free while leaving at least one broad surface of the layer tacky and pressure-sensitive. When a broad surface of the adhesive layer is thus made completely tack-free, the adhesive layer can be wound upon itself in roll form without a backing for convenient storage and shipment. Preferably a low-adhesion backsize coating covers the broad tack-free surface to insure that the adhesive layer can be unwound after prolonged storage without delaminating.

A polyhydridosilane has a catenated silicon backbone of 9 to 4000 silicon atoms with an average number of hydrogen atoms per silicon atom in the range of 0.3 to 2.2, at least 0.1 gram of the polyhydridosilane being soluble at 20.degree. C. in 100 grams of tetrahydrofuran, toluene, or methylene chloride. The polyhydridosilane can be derivatized or it can be converted to a pyropolymer or a nitrogen-containing pyropolymer which is useful as an abrasive, ceramic, electrical, or electro-optical material.
