Abstract

A water-soluable air-tight bag (10), the body of which comprises two laminations (1',1''), all of whose peripheries except the opening (2) are connected together; an opening-closing device (3,8,8') is arranged near the opening; said bag body (1) and opening-closing device (3,8,8') are made of water-soluable and biodegradable materials.

Description

technical field [0001] The present invention relates to a water-soluble and biodegradable mechanically or adhesively self-sealing tightly closed bag, especially for hygienic use. [0002] More specifically, the invention contemplates bags of the described type for enclosing hygienic items, such as bed sheets to be laundered in hospitals, and herbal medicine packs and / or fungicides and / or insecticides , or solid, powder or liquid compositions or formulations such as dyes and / or herbicides, powders or liquids; all such compositions or formulations are designed to be injected into water, especially into washing machines, respectively, for rinsing by spraying or dispensed water storage containers, injected into industrial mixers used to create varnishes and inks, or poured on land. Background technique [0003] Currently, commonly used bags for this type of use are suitably constructed of water soluble materials so that when the already prefilled bag is thrown into the water, i...
