Patent ID: 6969195

Claim:
A package, particularly for packing industrial products, comprising a product-holding body provided with a through-bore, a grip region associated to the body and a flow controlling and interrupting valve associated to the through-bore, the valve comprising an elongate and through-bored body of flexible material, the elongate and through-bored body being fixed by means of at least one first end portion thereof to the through-bore, one second end portion of the elongate and through-bored body, being opposed to the first portion, extending outwardly of the through-bore and being foldable over the elongate and through-bored body into the through-bore, so as to enable one to close the valve, the second end portion of the elongate and through-bored body being selectively foldable in the direction of the first region inside a cavity defined between the valve and the product-holding body, wherein the valve is positioned opposite the product-holding body from the grip region; the second end portion of the elongate and through-bored body is configured to be folded inwardly into the cavity, such that the weight of a product disposed in the product-holding body crushes the end portions of the tube when the valve is folded into the through-bore and the package is lifted by the arm region; the elongate and through-bored body is fixed to an internal portion of the through-bore by means of first and second opposed fixation regions, the second region being substantially larger than the first region; the fixation between the elongate and through-bored body and the internal portion of the through-bore in the second region is effected substantially over the whole region of contact between them both; and the valve is configured to remain folded even when subjected only to its own weight.
