Mouthpiece assembly for water bottles

Abstract

A mouthpiece assembly includes a mouthpiece mounted on a movable part which is mounted on an insertion tube of a base. The base is connected with a hose and two locking members extend from the base so as to hook the movable part. Two operation plates are connected on two sides of the movable part and two covers are pivotably connected with the two operation plates. The two covers enclose the mouthpiece. When the two operation plates are moved upward, the movable part is pulled away from the base so as to open the outlets defined in the movable part and the two covers are pivoted outward so that the mouthpiece is accessible. When pulling the operation plates downward, the movable part is re-seal the outlets in the base an the covers are pivoted inward to enclose the mouthpiece again.

1 . A mouthpiece assembly comprising: 
 a mouthpiece;    a base having a flange connected thereto and an insertion tube extending from a top of the flange, two locking members extending from the top of the flange and the insertion tube located between the two locking members, each of the two locking members having an engaging recess defined in a side thereof;    a movable part having a mounting tube in which the insertion tube is inserted, a seal rod located in the mounting tube and extending from a top of the mounting tube, the seal rod removably inserted in the insertion tube so as to seal the insertion tube, a plurality of outlets defined between the seal rod and the inner periphery of the mounting tube, a connection portion extending from the insertion tube and the mouthpiece mounted on the connection portion, two insertion holes defined on two first opposite sides of the movable par and each insertion hole having two notches defined in an inside thereof, two locking holes and a through hole defined in an outside of each insertion hole;    two covers located outside of the mouthpiece and enclosing the mouthpiece, each cover having two lugs on a lower end thereof and each lug having an elongate slot defined therethrough, a pivot connected to each of the two covers and the two lugs of each cover inserted into the two insertion holes respectively, the two pivots respectively engaged with the two engaging recesses of the two locking members, and two operation plates each having a positioning ridge on an upper portion and a lower portion of a side thereof and two protrusions extending from a mediate portion of each operation plate, the positioning ridges of each operation plate being engaged with the locking holes and the protrusions of each operation plate extending through the elongate slots and engaged with the notches.    
   
   
       2 . The assembly as claimed in  claim 1 , wherein the mouthpiece has a connection tube extending from an underside of the flange.  
   
   
       3 . The assembly as claimed in  claim 1 , wherein the movable part has two stops on two second opposite sides thereof and the two lugs each have a contact member which is in contact with the stop corresponding thereto when the two covers are opened.  
   
   
       4 . The assembly as claimed in  claim 1 , wherein the movable part has two ribs on two second opposite sides thereof and the two locking members each have a locking protrusion on an upper portion of each of the engaging recesses, the locking protrusions are engaged with the ribs  35  when the two covers are in closed positions.  
   
   
       5 . The assembly as claimed in  claim 1 , wherein each of the two covers has an engaging lip on one side and an engaging groove in the other side, so that when the two covers are matched with each other, the engaging lips are engaged with the engaging grooves corresponding hereto.  
   
   
       6 . The assembly as claimed in  claim 1 , wherein the insertion tube has a groove defined in an outer periphery thereof and a seal is engaged with the groove.  
   
   
       7 . The assembly as claimed in  claim 1 , wherein the mouthpiece has a plurality of reinforcement flanges on an outer periphery thereof.
