Adapter for connecting a vacuum system to a container and container therewith

Abstract

An adapter configured to be arrangeable on or in a wall of a container and configured to connect a vacuum system to said container. The adapter includes a first side configured to be directed towards an interior of the container and comprising an inlet, and a second side, opposite the first side, and configured to be directed outward relative to the interior of the container and comprising an outlet. A passage extends between the inlet and the outlet and includes a narrowing configured to cause a flow velocity at the inlet to be smaller than a flow velocity at the outlet. A sealing cap includes aforementioned specified adapter, and to an assembly includes a container and an adapter.

1 . An adapter configured to be arrangeable on or in a wall of a container and configured to connect a vacuum system to said container, comprising:
 a first side configured to be directed towards an interior of the container and comprising an inlet;   a second side, opposite the first side, and configured to be directed outward relative to the interior of the container and comprising an outlet; and   a passage extending between the inlet and the outlet;   wherein the passage comprises a narrowing configured to cause a flow velocity at the inlet to be smaller than a flow velocity at the outlet.   
     
     
         2 . The adapter according to  claim 1 , wherein the narrowing is defined at least in part by a cross sectional surface area of the inlet that is enlarged relative to a cross sectional area of the outlet. 
     
     
         3 . The adapter according to  claim 1 , further comprising an air permeable filter disposed at the inlet. 
     
     
         4 . The adapter according to  claim 1 , further comprising a filter support disposed at the inlet. 
     
     
         5 . The adapter according to  claim 4 , wherein the filter support comprises a plurality of ribs extending from an outer perimeter of the inlet. 
     
     
         6 . The adapter according to  claim 4 , wherein the narrowing comprises a stepped surface and the filter support comprises a plurality of protrusions arranged on the stepped surface of the narrowing. 
     
     
         7 . The adapter according to  claim 1 , further comprising a connector disposed at the second side of the adapter. 
     
     
         8 . The adapter according to  claim 1 , further comprising a locking element arranged on the second side of the adapter, wherein the locking element is configured to receive a locking counter-element of a sealing cap configured to seal off the adapter. 
     
     
         9 . The adapter according to  claim 1 , further comprising sealing cap, wherein the sealing cap comprises:
 an elastic self-resealing septum that, when punctured by a needle-like object followed by a subsequent removal of said object, reseals a puncture caused by the needle-like object.   
     
     
         10 . The adapter according to  claim 1 , further comprising a sealing cap, wherein the sealing cap comprises:
 a sensor configured to detect matter indicative of a leakage of the container in the interior of the container.   
     
     
         11 . The adapter according to  claim 8 , further comprising a connector disposed at the second side of the adapter, and a sealing cap, wherein the connector of the adapter is embodied by an internal screw thread; and
 the sealing cap comprises the locking counter-element, wherein the locking counter-element extends in a tightening direction of the connector to be received by the locking element.   
     
     
         12 . A sealing cap as described in  claim 9 . 
     
     
         13 . An assembly comprising at least a container and an adapter according to  claim 1 .
