FIELD: packaging industry.
SUBSTANCE: container comprises a housing 1 of a solid thermoplastic polymeric material with a cavity 2 which is closed by the lid 3 made of the same material on the side of the housing 1 with a rounded edge 5 lying in one plane, which in the cavity 2 of the housing 1 is smoothly coupled with its inner side surface circumscribed by the generants in the form of straight lines geometrically longitudinal to the housing 1, at least in a part adjacent to the rounded edge 5. Outside the housing 1 along its perimeter adjacent to the rounded edge 5 a closed projecting part 7 is made which has a cross sectional shape in the form of a continuous part with an outer surface, which is spaced from the outer surface 9 of the housing 1 and forms a closed undercut 10 on the side toward the bottom of the housing 1, and a continuous closed groove 12 on the side of a rounded edge 5. The continuous closed groove 12 is made V-shaped. One its lateral surface 13 is smoothly coupled with a rounded edge 5. The second 14 is provided with a projection 15 with the thrust surface 16 facing the bottom 17 at an angle to the surface 14 not exceeding a straight line with its apex turned away from the bottom 17. The lid 3 is made with a closed sealing groove 18 formed on the edge of the lid 3 by the branching part passing in a closed thrust part 21 oriented in the cross-section as a V-shape to the branching part and ending with the thrust edge. The rounded edge 5 of the housing 1 is located in the sealing groove 18 with a tight conjugation with its side surfaces of the part 24, which is adjacent to the rounded edge 5 of the housing 1, of the inner side surface 6 and the first side surface 13. The closed thrust part 21 is located with the contact on the thrust edge of the thrust part 21 with the thrust surface 16. The part 24, which is adjacent to the rounded edge 5, and the first lateral surface 13 are positioned relative to each other in their cross section at an acute angle with the apex on the side of the rounded edge 5.
EFFECT: container maintains the reliability and the impermeability of package when minor deformations of the housing and lid, due to various mechanical impacts on the container during its transportation, in particular when the container is lifted and lowered manually, which can be repeated several times.
