FIELD: transportation; packing; storage.
SUBSTANCE: invention relates to containers for storage or transportation of products, or materials, in particular, transportation of liquid by dosing devices (mechanical pumps), where pressure in the container is equal to atmospheric pressure, and can be used in agriculture, medicine, pharmacology, microbiology, personal hygiene, cosmetology, food and chemical industry. A device consisting of a flexible polymer or rubber tube and a weighting agent soldered (built-in) into the lower part of the tube.
EFFECT: by changing the design of the lifting tube, constant access of the intake part of the tube to the liquid was achieved, regardless of the angle of rotation of the bottle in the horizontal or vertical planes, which provides equal irrigation doses and virtually eliminates the ingress of air into the bottle.
