FIELD: construction.
SUBSTANCE: container comprises a reservoir, a hingedly fixed cover and a plate or a spiral spring, or a twist spring, or a torsion, with one end fixed on the cover or on the reservoir, and with the second end contacting accordingly with the reservoir or the cover after opening of the cover by the angle of 45-89 degrees. The other version of container design differs from the previous one only by the fact that the second end of springs or the torsion contacts until the cover is opened by the angle of 45-89 degrees. The next version of container design differs from the previous ones by the fact that the second end is fixed accordingly on the reservoir or on the cover. Besides, the neutral position of the spring corresponds to opening of the cover by 45-89 degrees.
EFFECT: increased angle of opening and reduction of sharp opening-closing.
