Vacuum insulated bottle with mechanism for dispensing liquid by compression

Claim 1

A vacuum insulated bottle including a liquid dispensing device comprising in combination: a. an outer bottle body; b. an inner bottle body disposed within said outer bottle body with said inner and outer bottle bodies each having an outlet at the respective upper end thereof; c. a stopper member disposed in the outlet of said inner bottle body in sealing relationship thereat, said stopper member having formed therein a generally vertically extending central duct means with a laterally extending branch passage extending upwardly at a slight inclination to the horizontal to the periphery of said stopper member, said central duct means and said laterally extending passage each having a valve seat adjacent the respective lower ends thereof and a valve element cooperating with each of said valve seats; d. an elastic pouch disposed above said stopper member with an opening tightly coupled with the upper end of said central duct; e. a lid disposed adjacent the top side of said outer bottle body adapted to be selectively lifted from and lowered to closed position, said lid including a downwardly extending cylindrical case with at least one generally vertically extending bar on the inner wall thereof, said bar having an upper edge or abutment, said lid also having at least one shaft element projecting downwardly for a short distance from the under side thereof, said lid further having an opening at its top; f. an activator member including a generally horizontally extending base in pressing contact with the upper end of said elastic pouch and a press portion extending through said opening at the top of said lid, said base having at least one slotted hole therein and a lateral flange with an outwardly opening groove; g. a suction pipe disposed within said inner bottle and having an upper end connected to the lower end of the central duct of said stopper member; and h. an outlet tube having a lower end connected with the fork or branch passage in said stopper member; wherein said outwardly opening groove of said lateral flange is registrable with said bar so as to be guided in vertical movement when said bar is disposed therein to thereby pump liquid from said inner bottle body, up said suction pipe, through said stopper member, into said elastic pouch, out said outlet tube by compressing said elastic pouch and allowing it to expand, said lateral flange may be raised above the upper edge of said bar at which height the downwardly projecting shaft element will penetrate the slotted hole in the lateral flange and the actuator member may be rotated to the extent that at least one portion of the lateral flange on one side of the outwardly opening groove will be above the upper edge or abutment of said bar and be locked against pumping action, with said downwardly projecting shaft element being operative to limit rotation of said activator to and from registration of said groove and said bar.
