  • the closure comprises askirt attached to the container and a cap for closing the spout, connected together by a tearable band.
  • the latter is limited by lines of perforations formed by grooves extending from the edges of this band. Ribs prevent relative motion of the closure when snapped over the container neck.
  • the present invention relates to a container such as a bottle, flask, etc., in which a pouring spout made of synthetic plastic material comprises an outer tubular sleeve intended to be pressed into the neck of the sa1d container and an inner sleeve or outlet of smaller diameter, the inner sleeve being connected to the outer sleeve by a wall provided with at least an air inlet connecting the space comprised between the two sleeves with the interior of the container, the end of the said inner sleeve or hp projecting beyond the edge of said outer sleeve.
  • it comprises also a closure provided with a skirt attached to the neck of the container and a cap to protect the said spout.
  • the invention provides thereby a container with a pouring spout and a closure providing at the same time sealing means for the container and closing means for the s out.
  • the pouring spout according to the invention is particularly useful, providing a perfectly regular iiow of the liquid out of the container for every possible rate of llow down to the smallest drip and on the other hand, it takes in the last drop of the liquid which has been poured out, which generally tends to soil the outer wall of the container in particular when this liquid is relatively viscous. Thanks t the above described arrangement, the last drop ows necessarily in the space comprised between the said two sleeves and returns finally into the container through the air inlet,
