<p>The invention discloses a method for manufacturing a top (1) to be fitted on a container or pliable tube (50) and comprising a neck (3) the aperture (7) of which is linked by a tearable ring-shaped portion (10) with an inner capsule (20) acting as a sealed closure before tearing of the ring-shaped portion, and usable after for reclosing. The method is characterised in that: a) the inner capsule (20) is prolonged by a plate (30) the periphery (31) of which has a common symmetrical axis with the tearable ring-shaped portion (10) and is fitted with three or more pins (32); b) the sidewall (40) is open at one end; its internal wall (46) is partially cylindrical, its cross section matching the shape, excluding lugs, of the periphery (31) of the plate, and is provided with three or more cavities (41) to house the said lugs; c) the sidewall is slipped round the plate (30) until it is stopped by the insertion of the lugs (32) of the plate (30) in the cavities (41) of the sidewall (40). The invention allows the manufacture at reduced cost of tubes for hygienic or cosmetic products.</p> |
