Packaging for liquid or pulverulent products

Packaging for liquid or pulverulent products, comprised of:

• a substantially rigid outer shell, the outer shell including lateral walls and a cover, the cover having an opening formed therein;
• a substantially flexible inner shell disposed in the outer shell for removably receiving the liquid or pulverulent product therein, the inner shell including a base, a body extending upwardly from the base, shoulders extending from the body opposite of the base, a neck extending from the shoulders opposite of the body and a spout extending from the neck opposite of the shoulders;
• the body of the inner shell being sufficiently flexible so as to substantially assume the shape of the lateral walls of the outer shell when liquid or pulverulent product is disposed therein;
• the shoulders of the inner shell being sufficiently flexible so that pressure exerted downwards on the spout deforms the shoulders so that the spout retracts inside the outer shell and further so that force exerted upwards on the spout deforms the shoulders so that the spout extends out from the outer shell, wherein the inner shell is in a position in which it can be filled or emptied via the spout;
• and
• a stopper removably disposed on the spout, so that the stopper can be selectively positioned on and removed from the spout when desired so that the contents of the inner shell may be selectively retained therein or removed therefrom;
• wherein the stopper further includes a retention member that interacts with the bottom of the cover when the spout is retracted inside the outer shell, thereby preventing the undesired emergence of the spout equipped with the stopper from the inside of the outer shell.
