Device for dispensing material into a container

Abstract

A dispenser comprising attachment means ( 844 ) for attachment to a container, a reservoir ( 822 ) for holding material ( 820 ), a barrier means ( 895 ) to prevent the material entering the container, wherein the barrier means is removable by manipulation of the dispenser, thereby permitting the material to be selectively dispensed into the container.

1 - 40 . (canceled)  
   
   
       41 . A dispenser comprising: 
 an attachment formation for attachment to a container;    a reservoir for holding material;    a barrier formation to prevent the material entering the container, the barrier formation being openable by manipulation of the dispenser, thereby permitting the material to be selectively dispensed into the container;    a closure provided in the dispenser to permit material to be removed from a container to which the dispenser may be attached via the dispenser without the need to remove the dispenser from the container; and    a conduit extending through the dispenser to permit the removal of material from the container via the closure, while bypassing the reservoir.    
   
   
       42 . A dispenser according to  claim 41 , wherein the conduit extends from the closure to a position at the same level as, or below the barrier formation.  
   
   
       43 . A dispenser according to  claim 41 , wherein the closure is arranged such that manipulation thereof further causes the material to be selectively dispensed.  
   
   
       44 . A dispenser according to  claim 41 , wherein the closure is reclosable.  
   
   
       45 . A dispenser according to  claim 44 , wherein the closure is a sports cap.  
   
   
       46 . A dispenser according to  claim 41 , wherein the dispenser further comprises one of a formation to substantially equalize the pressure it the reservoir and a formation to supply a positive pressure relative to a container to which the dispenser is attachable.  
   
   
       47 . A dispenser comprising: 
 a first portion;    a second portion;    an attachment formation for attachment to a container;    a reservoir for holding material;    a barrier formation to prevent the material entering the container, the barrier formation being openable by manipulation of the dispenser, thereby permitting the material to be selectively dispensed into the container;    wherein at least one of the first portion and the second portion comprises a manipulation control formation to control manipulation of the dispenser from a first closed position in which the barrier formation is in place to a second position in which the barrier formation is open, the control formation being configured to provide discrete axial and rotational components to the manipulation.    
   
   
       48 . A dispenser according to  claim 47 , wherein the first portion comprises the reservoir.  
   
   
       49 . A dispenser according to  claim 47 , wherein the second portion comprises the attachment formation.  
   
   
       50 . A dispenser according to  claim 47 , wherein the control formation is arranged such that the rotational component of the manipulation must precede the axial component of the manipulation.  
   
   
       51 . A dispenser according to  claim 50 , wherein the manipulation is controlled by a cam and a cam follower.  
   
   
       52 . A dispenser according to  claim 51 , wherein the cam comprises an axial cam portion and a rotational cam portion.  
   
   
       53 . A dispenser according to  claim 51 , wherein the cam comprises one of a recess and a surface and the cam follower comprises one of a projection and pin.  
   
   
       54 . A dispenser according to  claim 47 , wherein the axial movement slidably opens the barrier formation.  
   
   
       55 . A dispenser according to  claim 54 , wherein the axial movement to pen the barrier formation is a movement of the first portion towards the second portion.  
   
   
       56 . A dispenser according to  claim 47 , wherein the barrier formation comprises a plug, the plug being arranged to block a hole in the first position and to be displaced clear of the hole in the second position.  
   
   
       57 . A dispenser according to  claim 47 , wherein the first portion is integrally formed.  
   
   
       58 . A dispenser according to  claim 47 , wherein the reservoir comprises a scale to enable a predetermined amount of material to be dispensed.  
   
   
       59 . A method of dispensing a material from a reservoir of a dispenser into a container attached to the dispenser, the method comprising the steps of: 
 (1) rotating a first portion of the dispenser relative to a second portion of the dispenser; and    (2) axially displacing the first portion relative to the second portion.
