Accurate Lid with Spout for Closing a Liquid Container

Abstract

A container ( 3 ) closing lid ( 1 ) whose top part forms a spout ( 2 ) provided with a sliding shutter ( 4 ) driven by a spring ( 5 ) and controlled in the displacement thereof by a pivotable opening lever, wherein additional elements are provided between the spout ( 2 ) and the lever for increasing the spring ( 5 ) pressure force and the lid is handled via a grip handle ( 9 ). The inventive lid is characterized in that at least one part of the grip handle ( 9 ), elements for fixing the lid to the container ( 3 ) and elements for permanently pressing the spring ( 5 ) are formed in an integral manner with the lid ( 1 ) in such a way that an accurate lid ( 1 ) having a simplified structural design is obtainable.

1 . Precision cover ( 1 ) with a spout ( 2 ) for closing the liquid container ( 3 ) of the type in which the top of the cover ( 1 ) forms a spout ( 2 ) with a sliding shutter ( 4 ) that is acted upon by a hairpin spring ( 5 ) whose motion is controlled by a pivoting opening lever ( 6 A,  6 B), whereby additional means ( 7 ,  8 ) are provided between spout ( 2 ) and lever ( 6 A,  6 B) to increase the pressure force of the spring ( 5 ) that is thus acted upon in flexion and torsion for the purpose of ensuring, via the same spring ( 5 ), a double action of pressure and automatic re-closing of the sliding shutter ( 4 ), whereby said cover ( 1 ) is manipulated via a gripping handle ( 9 ), characterized in that at least a portion of the gripping handle ( 9 ), the means ( 12 ) for attaching the cover ( 1 ) to the container ( 3 ) and the means ( 7 ,  8 ) for exerting continuous pressure on the spring ( 5 ) are formed by a single part, in particular obtained from molding, with said cover ( 1 ) for obtaining a precision cover ( 1 ) with simplified construction.  
   
   
       2 . Precision cover ( 1 ) with a spout ( 2 ) according to  claim 1 , wherein the means ( 7 ,  8 ) for exerting continuous pressure on the spring ( 5 ) that ensure, via the spring ( 5 ), a minimum continuous pressure on the shutter ( 4 ) that ensures a better sealing consist of a double square ( 7 ) or a T-shaped section ( 8 ) that extends between the essentially parallel branches of the pin spring ( 5 ), whereby the branch of the T or the horizontal square, relative to the cover ( 1 ), rest on a branch of the spring ( 5 ).  
   
   
       3 . Precision cover ( 1 ) with spout ( 2 ) according to  claim 1 , wherein the means ( 12 ) for attaching the cover ( 1 ) to the container ( 3 ) consist of a threading of said cover ( 1 ) that allows the cover ( 1 ) to be screwed onto the container ( 3 ).  
   
   
       4 . Precision cover ( 1 ) with spout ( 2 ) according to  claim 1 , wherein the control lever ( 6 A,  6 B) for movement of the sliding shutter ( 4 ) rests in a V-shaped cavity ( 13 ) made in the cover ( 1 ), whereby this lever assumes the form of a catch of which the branch ( 6 A) that is inserted into the cavity constitutes a support stop of one end of the pin spring ( 5 ) with two flanges and of which the other end is coupled to the sliding shutter ( 4 ), whereby the strands of said spring ( 5 ) are wound on shafts that are formed at the junction of the two branches that the catch forms.  
   
   
       5 . Precision cover ( 1 ) with spout ( 2 ) according to  claim 1 , wherein the cover ( 1 ) has, on both sides of the handle ( 9 ), flanges ( 10 ) for the suspension of the container ( 3 ), in particular in a rail ( 11 ).  
   
   
       6 . Precision cover ( 1 ) with spout ( 2 ) according to  claim 2 , wherein the means ( 12 ) for attaching the cover ( 1 ) to the container ( 3 ) consist of a threading of said cover ( 1 ) that allows the cover ( 1 ) to be screwed onto the container ( 3 ).  
   
   
       7 . Precision cover ( 1 ) with spout ( 2 ) according to  claim 2 , wherein the control lever ( 6 A,  6 B) for movement of the sliding shutter ( 4 ) rests in a V-shaped cavity ( 13 ) made in the cover ( 1 ), whereby this lever assumes the form of a catch of which the branch ( 6 A) that is inserted into the cavity constitutes a support stop of one end of the pin spring ( 5 ) with two flanges and of which the other end is coupled to the sliding shutter ( 4 ), whereby the strands of said spring ( 5 ) are wound on shafts that are formed at the junction of the two branches that the catch forms.  
   
   
       8 . Precision cover ( 1 ) with spout ( 2 ) according to  claim 3 , wherein the control lever ( 6 A,  6 B) for movement of the sliding shutter ( 4 ) rests in a V-shaped cavity ( 13 ) made in the cover ( 1 ), whereby this lever assumes the form of a catch of which the branch ( 6 A) that is inserted into the cavity constitutes a support stop of one end of the pin spring ( 5 ) with two flanges and of which the other end is coupled to the sliding shutter ( 4 ), whereby the strands of said spring ( 5 ) are wound on shafts that are formed at the junction of the two branches that the catch forms.  
   
   
       9 . Precision cover ( 1 ) with spout ( 2 ) according to  claim 2 , wherein the cover ( 1 ) has, on both sides of the handle ( 9 ), flanges ( 10 ) for the suspension of the container ( 3 ), in particular in a rail ( 11 ).  
   
   
       10 . Precision cover ( 1 ) with spout ( 2 ) according to  claim 3 , wherein the cover ( 1 ) has, on both sides of the handle ( 9 ), flanges ( 10 ) for the suspension of the container ( 3 ), in particular in a rail ( 11 ).  
   
   
       11 . Precision cover ( 1 ) with spout ( 2 ) according to  claim 4 , wherein the cover ( 1 ) has, on both sides of the handle ( 9 ), flanges ( 10 ) for the suspension of the container ( 3 ), in particular in a rail ( 11 ).
