FIELD: manufacturing technology.
SUBSTANCE: invention relates to a cap, which can be used for sealing of any type of container, used in laboratory analyses, particularly a container containing a reagent required for analysis reaction. Cap comprises body (32), opening (34) passing through cap (30) and adapted in turn to be passed through by at least one product transfer member (20), and membrane (40) which, at rest, covers opening (34). Membrane (40) has a main portion that extends through opening (34) and defines two inclined faces (45A, 45B), each having distal edge (46A, 46B). Two inclined faces (45A, 45B) form a dihedron when membrane (40) is at rest, distal edges (46A, 46B) of two inclined faces come together at apex (47) of dihedron. Cap comprises at least two flaps (35A, 35B) that extend through opening (34), above membrane (40), two inclined faces (45A, 45B) of membrane being respectively covered by flaps (35A, 35B), each flap having free edge (36A, 36B) that extends along distal edge of corresponding inclined face.
EFFECT: disclosed cap reduces possibility of jamming of tip of reagent-transfer element in membrane.
