Closable drinking container

Abstract

A drinking container in which a tube is movable between a closed sealing position and an open drinking position. The tube and the bottom of the container, when in the closed sealing position, are sealed by a closing element. The closing element, when in the open drinking position, uncovers the interior of the tube in such a way that liquid can be withdrawn from the receiving chamber via the tube.

1 . A drinking container comprising: 
 a cup-like element, which forms a receiving chamber and is firmly closable using a lid element and which has a bottom across from the lid element, a drinking unit being provided in the lid element, the drinking unit including a guide element situated in the lid element for receiving a tube, the lower end of which reaches down to the region of the bottom of the container, wherein the tube is movable between a closed sealing position and an open drinking position, tube and bottom in the closed sealing position being sealed by a closing element which in the open drinking position uncovers the interior of the tube such that liquid can be withdrawn from the receiving chamber via the tube.    
   
   
       2 . The drinking container as recited in  claim 1 , wherein the closing element includes a depression provided in the bottom.  
   
   
       3 . The drinking container as recited in  claim 2 , wherein the closing element further includes a lower seal at the lower end of the tube.  
   
   
       4 . The drinking container as recited in  claim 1 , wherein in the region of the passage through the lid element an upper seal is provided between the tube and guide element.  
   
   
       5 . The drinking container as recited in  claim 1 , wherein the tube is movable from the open drinking position to the closed sealing position by a sliding motion.  
   
   
       6 . The drinking container as recited in  claim 1 , wherein the tube can be moved from the open drinking position to the closed sealing position by a rotary motion.  
   
   
       7 . The drinking container as recited in  claim 6 , wherein an external thread is provided on the tube and a corresponding internal thread is provided in the guide element.  
   
   
       8 . The drinking container as recited in  claim 1 , wherein between the guide element and the tube a holding arrangement is provided for sealing the tube in the open drinking position.  
   
   
       9 . The drinking container as recited in  claim 1 , wherein the part of the tube that protrudes above the container is made of a flexible material.  
   
   
       10 . The drinking container as recited in  claim 2 , wherein on the bottom adjacent to the depression a guide extending into the receiving chamber is provided.  
   
   
       11 . The drinking container as recited in  claim 2 , wherein the depression is centered in the bottom and the drinking unit is correspondingly centered in the lid element.  
   
   
       12 . The drinking container as recited in  claim 2 , wherein the depression is arranged eccentrically and near the periphery of the bottom and the drinking unit is correspondingly arranged eccentrically and near the periphery of the lid element.  
   
   
       13 . The drinking container as recited in  claim 2 , wherein the bottom is formed such that it slopes downward to the depression.  
   
   
       14 . The drinking container as recited in  claim 1 , wherein in the upper region of the guide element a pressure-equalizing arrangement is provided, which in the closed sealing position is closed by the upper seal.  
   
   
       15 . The drinking container as recited in  claim 14 , wherein the pressure-equalizing arrangement takes the form of a bore hole.  
   
   
       16 . The drinking container as recited in  claim 1 , wherein, by a surrounding jacket, the container takes the form of a thermal container.  
   
   
       17 . The drinking container as recited in  claim 1 , wherein the tube features a suction nozzle in the region outside of the lid element.  
   
   
       18 . The drinking container as recited in  claim 1 , wherein the suction nozzle takes the form of a handle for moving the tube.  
   
   
       19 . The drinking container as recited in  claim 1 , wherein the drinking unit has a cover as a closure of the tube in the region outside of the lid element.  
   
   
       20 . The drinking container as recited in  claim 1 , wherein the lid element has along its periphery an elastic and grip-providing rim element.  
   
   
       21 . A combined drinking and closing arrangement, comprising the closing element and the drinking unit of a drinking container as recited in  claim 1 .  
   
   
       22 . A method comprising the steps of: 
 storing a liquid in a drinking container as recited in  claim 1.
