Drinking vessel

Abstract

A drinking vessel comprising a container having a mouth and an internal shoulder; a cap for closing the mouth of the container and having an outlet for liquid; and a valve unit removably mountable on the cap and arranged to control flow of liquid to the outlet; the valve unit being so arranged that the shoulder prevents the valve unit from being separated from the cap while the cap is mounted on the container. Also, a drinking vessel comprising a container having an outlet for liquid; and a receptacle removably attachable to an end of the container remote from the outlet of the container; wherein the receptacle comprises parts relatively movable between a substantially closed position and a position providing an orifice for releasing objects from within the receptacle; wherein the receptacle is arranged to be attached to the container in such a position that the container closes off the orifice.

1 . A drinking vessel comprising: 
 a container for retaining a quantity of liquid, the container having a mouth and an internal shoulder;    a cap for closing the mouth of the container and having an outlet for liquid; and    a valve unit removably mountable on the cap and arranged to control flow of liquid to the outlet;    the valve unit being so arranged that the shoulder prevents the valve unit from being separated from the cap while the cap is mounted on the container.    
   
   
       2 . The drinking vessel of  claim 1 , wherein the valve unit is positioned within a seat formed in the cap, and the shoulder prevents movement of the valve unit away from the seat.  
   
   
       3 . The drinking vessel of  claim 2 , wherein the valve unit is tapered, and the valve unit is a push fit into the seat.  
   
   
       4 . The drinking vessel of  claim 2 , wherein the valve unit comprises a tubular part that fits into the seat and a base part extending away from the tubular part to engage the shoulder.  
   
   
       5 . The drinking vessel of  claim 1 , wherein the mouth and the shoulder are circular and the shoulder is generally coaxial with the mouth.  
   
   
       6 . The drinking vessel of  claim 5 , wherein the cap and the container have matching screw threads such that the cap may be screwed onto the mouth of the container.  
   
   
       7 . The drinking vessel of  claim 1 , further comprising a receptacle removably attached to an end of the container remote from the mouth of the container.  
   
   
       8 . The drinking vessel of  claim 7 , wherein said receptacle comprises a lid and a body, and the lid of said receptacle is removably attached to the container.  
   
   
       9 . The drinking vessel of  claim 7 , wherein the container has a groove encircling it, and the receptacle has a lip with a bead engaging in the groove.  
   
   
       10 . The drinking vessel of  claim 1  further comprising: 
 a receptacle removably attachable to an end of the container remote from the outlet of the container;    wherein the receptacle comprises a first housing part having first and second peripheral skirts extending on opposite sides of a middle portion, a second housing part, and a third part;    said container and one of said skirts having first mating formations removably attaching said one skirt to said container;    said second housing part and the other of said skirts having second mating formations removably attaching said other skirt to said second housing part;    said first and second housing parts defining between them an interior space of said receptacle;    said first body part defining an orifice for releasing objects from within the receptacle;    said third part being rotatable relative to said first body part to open and close said orifice; and    said receptacle being arranged to be attached to the container in such a position that the container closes off the orifice.    
   
   
       11 . A drinking vessel comprising: 
 a container for retaining a quantity of liquid, the container having an outlet for liquid; and    a receptacle removably attachable to an end of the container remote from the outlet of the container;    wherein the receptacle comprises parts relatively movable between a substantially closed position and a position providing an orifice for releasing objects from within the receptacle;    wherein the receptacle is arranged to be attached to the container in such a position that the container closes off the orifice.    
   
   
       12 . The drinking vessel of  claim 11 , wherein the relatively movable parts are relatively rotatable between said position in which said orifice is open and said position in which said orifice is substantially closed.  
   
   
       13 . The drinking vessel of  claim 11 , wherein: 
 the receptacle further comprises a first housing part having first and second peripheral skirts extending on opposite sides of a middle portion and a second housing part;    said container and one of said skirts having first mating formations removably attaching said one skirt to said container;    said second housing part and the other of said skirts having second mating formations removably attaching said other skirt to said second housing part;    said first and second housing parts defining between them an interior space of said receptacle.    
   
   
       14 . The drinking vessel of  claim 13 , wherein at least one of said first mating formations and said second mating formations comprises mating screw threads.  
   
   
       15 . The drinking vessel of  claim 13 , wherein at least one of said first mating formations and said second mating formations comprises a bead mating with a groove.  
   
   
       16 . The drinking vessel of  claim 11 , wherein the container and the receptacle have first mating formations on the container and on the receptacle removably attaching said receptacle to said container, and said receptacle has a second mating formation on the receptacle corresponding to the first mating formation on the container, such that the first mating formation on an identical second receptacle is removably attachable to said second mating formation on said receptacle.  
   
   
       17 . The drinking vessel of  claim 16 , further comprising a base having a mating formation removably attachable to said first mating formation on said receptacle or to said second mating formation on said receptacle.  
   
   
       18 . The drinking vessel of  claim 11 , further comprising a valve unit removably mountable on the container and arranged to control flow of liquid to the outlet.  
   
   
       19 . The drinking vessel of  claim 18 , wherein the container has a cap for closing the mouth of the container and an internal shoulder; wherein the outlet is on the cap; and wherein the valve unit is so arranged that the shoulder prevents the valve unit from being separated from the cap while the cap is mounted on the container.  
   
   
       20 . The drinking vessel of  claim 11  further comprising at least one additional receptacle removably attachable to an end of a previous receptacle.
