ABSTRACT:
A tube (1) including a head (2) of molded plastic composition and a flexible sidewall (4) affixed to this head (2), including a neck (6 and 7) with an opening (8) connected by a detachable sealed annular portion (11) to a continuous bottom (12) of a closure (20) in the form of an inverted hat topping the neck, the bottom (12) of the closure being joined to an external sidewall (13) of the closure, and the closure carrying a means (17) for reclosing the neck in a sealed manner after the detachment of said annular portion (11). The neck has an inner annular edge (7) demarcating its opening (8), the edge (7) and an annular portion (14 and 15) of the closure (20) that extends from the junction of the base (12) and the annular detachable portion (11) up to an annular portion of the external sidewall (13) located above the connection (16) of the base (12) and the sidewall (13) each have a thickness of between 1.1 and 1.6 mm, their rigidity thus promoting the detachment of the detachable annular portion (11).
