Container having a displaceable valve portion for the controlled dispensing of a service fluid

Abstract

The invention concerns a container for storing and delivering fluid to viscous products. The container comprises a container body ( 1 ) having an opening ( 4 ) which is suitable for filling and the diameter (d 4 ) of which is smaller than the diameter (d 5 ) of the container body, and a lid ( 8 ) which serves to close the opening ( 4 ). The lid has a central lid opening ( 9 ) in which a delivery valve ( 10 ) which has a valve portion is sealingly fitted by means of a shaped portion ( 11 ). It is an advantage that the container can be very easily, quickly and inexpensively manufactured, filled and closed. At the same time the arrangement provides for easy controllable delivery of the filling product and reliable sealing closure of the product in the container after each product removal operation.

       22 . A valve lid for sealingly closing a container body and for the delivery of fluid to viscous products,
 comprising a round opening in which a delivery valve which has a cylindrical valve body as a valve portion and a shaped portion in sleeve form is fixedly and sealingly inserted solely by means of the shaped portion, wherein the round opening is defined by an axially outwardly or upwardly projecting collar; wherein the shaped portion is elastic in respect of shape and the valve portion is movable with elastic deformation of the shaped portion, characterised in that a flat panel portion (panel) radially outwardly adjoins the collar, which panel portion near its outer edge has a damping bead which in turn is radially outwardly adjoined by a folded edge configuration with which the valve lid can be connected to a flange edge of the container body.   
   
   
       23 . A valve lid according to  claim 22  characterised in that the collar above and below can be sealingly and fixedly embraced by respective holding portions arranged at a corresponding axial spacing of the hollow-cylindrical shaped portion. 
   
   
       24 . A valve lid according to  claim 22  characterised in that the cylindrical body of the valve is arranged without play in the hollow-cylindrical shaped portion and is sealingly held by means of further radial collars which are arranged at an axial spacing and which engage over axial ends of the shaped portion. 
   
   
       25 . A valve lid according to  claim 23  wherein at least some of the radial collars are peripherally continuous. 
   
   
       26 . A valve lid according to  claim 22  characterised in that the hollow-cylindrical shaped portion is fitted in the form of a sleeve fixedly and sealingly in the lid and the valve portion is movable in relation to the sleeve, to form the valve. 
   
   
       27 . A valve lid according to  claim 22  characterised in that the valve lid is suitable for controlling the delivery of fluid to viscous filling products, and in relation to the fixedly inserted hollow-cylindrical shaped portion, by a sliding displacement of the cylindrical body as a valve portion controls opening and closing of the valve arrangement, utilising the elasticity in respect of shape of the shaped portion. 
   
   
       28 . A valve lid according to  claim 23  characterised in that the outwardly projecting collar is fixedly embraced by the holding portions of the hollow-cylindrical shaped portion, so that the valve arrangement is held, even upon actuation of the valve portion and upon the occurrence of actuation pressure being applied to the valve portion. 
   
   
       29 . A valve lid according to  claim 24  characterised in that the cylindrical body of the delivery valve is sealingly held in the hollow-cylindrical shaped portion by means of the further radial collars, so that it cannot be released from said holding position. 
   
   
       30 . A valve lid according to  claim 27  characterised in that the at least some of the radial collars are peripherally continuous. 
   
   
       31 . A valve lid according to  claim 27  characterised by a centrally arranged round opening. 
   
   
       32 . A valve lid according to  claim 22  characterised in that the elasticity in respect of shape provides a spring action and a sealing action. 
   
   
       33 . A valve lid according to  claim 22  characterised in that the valve portion near one end has at least one radial window. 
   
   
       34 . A valve lid according to  claim 33  characterised in that there are provided three or more windows, near the lower collar of the valve portion, which lower collar serves as a valve disc. 
   
   
       35 . A valve lid according to  claim 22  characterised in that the movement of the valve portion is permitted by the elasticity in respect of shape of the shaped portion, with symmetrical deformation at least of an upper part of the shaped portion. 
   
   
       36 . A valve lid according to  claim 22  characterised in that the movement of the valve portion is permitted by the elasticity in respect of shape of the shaped portion, with asymmetrical deformation at least of an upper part of the shaped portion. 
   
   
       37 . A container for storing and—in any steps—delivering fluid to viscous filling products as filling fluids,
 comprising a container body having an opening which is suitable for filling and the diameter of which is smaller than a diameter of the container body; and   a valve lid which is suitable for or serves for closing the opening according to  claim 22 .   
   
   
       38 . A container according to  claim 37  characterised in that it is in the form of a drinks can stretched from metal sheet, wherein the container body is provided with a bottom formed integrally on the container wall and the lid at its edge is so adapted to be fixedly and sealingly connected to a container body edge or is already connected thereto by way of a fold configuration. 
   
   
       39 . A container according to  claim 37  characterised in that the valve lid with delivery valve comprising a valve portion and a shaped portion is a pre-assembled unit which can be sealingly and fixedly connected to an edge of the body of the container, by way of a fold configuration. 
   
   
       40 . A method of filling a container according to  claim 37  wherein filling material is introduced prior to assembly of the valve-lid unit into the body of the container and a further different or identical filling material is introduced into the container which is closed with the lid unit through the valve.
