Abstract: A protective cover for a drink opening in a liquid container. The cover has openings large enough to drink through but small enough to prevent insects, such as bees, from entering the liquid container. The cover contains a portion which will fit under the tear tab on a conventional drink container and the tab will secure the cover to the container, but will allow it to be removed when the container is thrown away and, thereby, reused.

Abstract: This invention is a catamenial pad or a tampon or a diaper which contains carboxymethylalginate (CMA) and alginic acid salt. The pad or diaper can be made from fibers composed of CMA alone or a mixture of CMA and alginic acid salt. CMA may be prepared by reacting chloroacetic acid, NaOH, and an alginic acid salt dispersed in a liquid aliphatic alcohol. More in detail, CMA can be prepared by a reaction in which sodium alginate is dispersed into ethanol, reacted with NaOH and chloroacetic acid at 40.degree.-50.degree.C. with agitation. The CMA can be spun into fibers and then it can be prepared into non-woven fabric. The fabric pad or diaper can be made into various designs. The fabric or the fiber has high absorbency, water-retentivity, stability, and coagulating ability against blood.
