Connector for Bottle-Like Containers

Abstract

The present invention concerns a connector ( 1 ) able to be mounted on the neck of a container for liquids ( 100 ), in the form of a bottler consisting of a main body having, sliding longitudinally therein, a slider provided with a radially expandable bottom portion so as to engage reversibly with a hollow:, probe, in which the hollow probe is able to perform the longitudinal displacement of the the slider and connect the inside of the container ( 100 ) with its interior so as to allow the dispensing of liquid from the container.

1 . Connector able to be mounted on the open end of the neck of a bottle, the connector having a main longitudinal axis X-X and comprising:
 a main body, which comprises constraining means for constraining the connector to the container and a sleeve able to connect the inside of the container to the external environment;   a slider which is slidably inserted in the sleeve and is able to love longitudinally between a closed bottom position, where the slider does not allow liquid to flow out from the container, and an open upper position, where the slider allows liquid to flow out from the container; the slider defining internally a seat able to receive a probe able to allow dispensing of the liquid;   the slider further comprising:   a central portion able to be guided at least partially by the sleeve;   a bottom portion, protruding from the sleeve towards the outside of the container when the slider is in the bottom closed position, and comprising a plurality of longitudinally elongated parts, which, when the slider Is in the bottom closed position, reversibly engage with a corresponding engaging portion formed in the probe by expanding elastically in a radial direction with respect to the longitudinal axis X-X,   wherein the connector further comprises an upper portion having a conical shape terminating in an end having the outer diameter d 4  such as to engage, with slight interference, with the upper portion of the main body;   the main body having, in the vicinity of its upper end, a circumferential projection projecting towards the inside of main body and with an inner diameter d 5 , the connector being such that when the upper portion of the slider passes over the projection, the bottom portion of the slider is situated inside the sleeve.   
   
   
       2 . Connector according to  claim 1 , in which the longitudinally elongated parts each comprise a tooth. 
   
   
       3 . Connector according to  claim 1 , in which the main body comprises:
 a sleeve with an inner diameter d 1 ;   an upper portion having an inner diameter d 3 >d 1 ;   the sleeve being longitudinally closer to the mouth of the container than the upper portion, when the connector is fixed to the container;   the upper portion comprising a circumferential projection projecting towards the, inside of the main body and having a height h such that h<d 5 −d 3 /2.   
   
   
       4 . Connector according to  claim 1 , in which the slider comprises:
 a central portion with an outer diameter d 2 ;   an upper portion having an outer diameter d 4 >d 2 ;   the central portion being longitudinally closer to the mouth of the container than the upper portion, when the connector is fixed to the container and the slider is in the bottom closed position.   
   
   
       5 . Connector according to  claim 4 , wherein the inner diameter d 1  of the sleeve is such to provide a liquid-tight seal when the sleeve is engaged with the outer surface of the slider or with the central portion of the slider or with the outer surface of the channel of the probe. 
   
   
       6 . Connector according to  claims 3  and  4 , in which d 1  is substantially equal to d 3 , and d 2  is substantially equal to d 4 . 
   
   
       7 . Connector according to  claim 1 , the slider comprising a generally flat base between its central and bottom portions.
