Description

The existing types of cardboard bits I vicious means - traffic jams, capsules, I prrzhladok-for sealing vodka, wine, alcohol, artificial and natural mineral water, beer, etc., have the disadvantage that they are water and alcohol permeable and soak under the action the above liquids, as a result of which the closure becomes unreliable. Well-known ... nowadays methods for producing waterproof cardboard, such as: impregnation with bitumen, then adhesive substances, followed by tanning (formalin, alum, etc.). For the needs of the food industry, they cannot be: applied, as the closures and containers made from these cardboards either contain substances that are harmful to health or inform the contents of an unpleasant smell of bitumen, which completely excludes the possibility of using such cardboard and such whipping. Another known method of impregnation with paraffin eliminates-, s; - :, since, eo first, paraffin is dissolved (in small quantities) in alcohol, secondly, the sealing made of such cardboard is not elastic and acquires greater rigidity; Consequently, :

its basic quality, by virtue of which corresponding cardboard products can be used as a surrogate for capping, is lost.

The proposed method for communicating the water and alcohol permeability to the board is as follows. The cardboard sheets are soaked with petroleum jelly (normal or melted) by one-sided or two-sided spreading, spraying, or other means known in the literature and in practice. The cardboard processed by the method described is manufactured by methods known in the art, for example by stamping, the required closures and other products, such as surrogates, corks, gaskets, boxes, cans, etc. When used for impregnating vaseline cardboard, brand), products made from this cardboard can be used in the food industry.

The properties of water- and alcohol-proof cardboard closures and other cardboard products can also be made by impregnating vaseline directly on ready-made products using methods known in the art, for example by coating with heated or melted vaseline, by spraying, treating vaseline-impregnated sawdust in a rotating drum with heating, etc.

The subject matter of the invention. A method of making cappings and liners made of cardboard for capping vodka, wine, beer, artificial and natural mineral waters, etc., characterized in that the cardboard is impregnated with natural petroleum jelly.
