| 摘要 |
One describes 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 body being fixed by means of at least its first end portion to the through-bore, the second end portion of the body, opposed to the first portion, extending outwardly of the thorough-bore and being foldable over the elongate body into the bore, so as to enable one to close the valve. The present package permits partial consumption of the product and the correct application, through the valve, thus enabling one to use the product partly and rationally, without wasting it. It also avoids leakage of the packed product, which is of great importance when toxic and polluting products are packed.
