Abstract:
A one piece cap for closing a liquid container of the type to be installed for a supply purpose in an upside down position onto a liquid dispenser, the container having a neck on which the cap sealingly mounts and through which a liquid supply tube passes when the container is installed onto the dispenser, said cap comprising:a lid having a surface area substantially conforming to a surface area of the neck; anda skirt projecting from the lid;said skirt having an internal face including gripping means for sealing the neck of the liquid container,said lid having a central recess including a tubular guiding portion projecting from the lid in a same direction as the skirt, said guiding portion being sized and positioned to receive the supply tube,said central recess also including a bottom portion in the form of a cone that projects away from the guiding portion, said cone being provided with a number of frangible lines extending within meridian planes in such a manner so as to allow splitting of said cone into a corresponding number of petal-shaped segments each having a tip when the container is installed onto the dispenser and its cap and neck are penetrated by the supply tube,said cone also having a truncated top and a peripheral surface forming an annular, outwardly projecting step of a generally V-shaped cross-section that is adjacent to said guiding portion and defines an annular inner flange at a distance from said top,whereby, in use, when the cone is split, said flange comes into contact with the supply tube and causes the tips of said segments to extend at a short distance away from the tube.
