<p>An airtight valvular container with a closed appendix (1) at its lower side where the exhaustion valve is assembled so as to permit the exhaustion of the content through an exhaustion tube without using mechanical means. Some apertures at the upper side permit the vertical handling for transportation and final use. The production is performed by a bag filler fully adapted for the simultaneous assembling of the exhaustion valve, filling of the selected product and weldings. The four feet of the holder that sustains the container during final use are of adequate shape so as to permit the assembling over a water dispenser which net of internal pipes has been adjusted to keep the whole system completely sealed and airtight.</p> |
