Abstract: The present invention relates to an improvement of a discharge container with a nozzle for housing a liquid, for example, an instantaneous adhesive or another moisture curing type adhesive, various adhesives such as solvent volatilizing type adhesive, various chemicals, foods, inks and medical supplies. The present invention is a discharge container with a nozzle which includes a container body for housing contents, a nozzle threadly attached to the container body, and a dual-shoulder type protective frame having a neck hole, wherein the base end of the mouth of the container body is inserted through the neck hole of the dual-shoulder type protective frame, and the container body is threadly attached to the nozzle, thereby allowing them to be made a one-piece structure.

Abstract: The present invention relates to an improvement of a nozzle cap for a composite container containing a low-viscosity liquid such as a humidity-curing type adhesive of .alpha.-cyanoacrylate-based adhesive, solvent-volatile type adhesive, various chemicals, food, and ink. A container is provided with a nozzle cap which includes a nozzle connected to a container body and a cap threadably mounted to the nozzle for closing a discharge port of the nozzle. A head of the cap is provided with a column element projecting inwardly for closing the nozzle and a head of the column element is provided with a concave hole into which the tip of the nozzle is removably inserted or fitted. A superior, unique effect is exhibited such that the closure of the nozzle is easily and completely performed, and adhesive or the like adhering to the tip of the nozzle does not spread around and cure, thereby preventing formation of an umbrella- or mushroom-shaped solid material.

Abstract: Ethylene-vinyl acetate copolymer compositions useful as adhesives, vibration-damping compositions or coating compositions which comprises a saponification product or a grafted saponification product of an ethylene-vinyl acetate copolymer and at least one aliphatic or aromatic polycarboxylic acid or anhydrides thereof.
