FIELD: food industry.
SUBSTANCE: on-off valve made so that it can be placed on packing and opened at excessive pressure inside of packing is suggested. A layer of adhesive is formed with an orifice aimed at joining while using with an orifice of packing. An additional elastic layer of adhesive is applied over the first layer. Two layers of adhesive are joined with each other so that when the valve opens it discloses a preliminary formed channel ensuring a pass-through between the layers of adhesive. Adhesive substance of the additional layer is spread over a surface, which forms part of the inner surface of the preliminary formed channel between two layers of adhesive.
EFFECT: valve has a high reliability when it's closed after first heating.
