PACKAGE FOR SMOKING AND SIMILAR MATERIALS Russian patent published in 2010 - IPC B65D85/10 

FIELD: packing industry.

SUBSTANCE: pack includes outer case (O) and inner case (I) connected by spring element (12). Outer case (O) forms a cavity for location of inner case (I) and includes lower wall (4 B), having four sides, front wall (1) and two side walls (3R, 3L), lifting from according edges of lower wall. Inner case (I) has front wall (11), back wall (7) and two sides walls (8R, 8L), besides back wall is connected to lower wall of outer case. Spring element (12) is connected hingedly by means of the first hinged joint (HI) near lower part of front wall (11) of inner case and by means of the second hinged joint (H2) near upper edge of spring element till relatively upper position on inner surface of front wall of outer case separated by gap from upper part of outer case. Inner case (I) is connected hingedly to outer case (O) by means of the third hinged joint (H3) near lower wall. Sum of gap value to the first hinged joint from the second joint and gap value to the first hinged joint to the third hinged joint is more than gap value to the second hinged joint from the third joint, therefore, inner case springs between the first opened position outside outer case, in which content of inner case is accessible, and closed position inside outer case, in which content is not accessible.

EFFECT: provision of pack, inner case of which relative to the outer one moves under improved spring-loaded action between closed and open position, and possibility of improved access to pack content.
