Cover mountable to beverage container and mounting method and apparatus thereof

A method for mounting a container cover which is mountable to a beverage container, comprising the steps of:

• loading a container end, the container end having a pull tab coupled to an upper surface of the container end via a central pin, the pull tab providing leveraging means for opening a discharging opening in the container end when an end of the pull tab is lifted;
• moving the loaded container end in a predetermined direction;
• sensing and aligning in a predetermined orientation the moved container end;
• and
• mounting a container cover between an upper surface of the container end and a pull tab around the central pin, the container cover comprising a body of substantially a disc-shaped configuration, the container cover having apertures selectively formed in the body, the apertures including a beverage discharging opening, a plurality of filtering holes and a straw insertion hole, the beverage discharging opening being formed in such a manner that it is communicated with the discharging hole, thereby allowing a beverage accommodated in the beverage container to be discharged out of the beverage container through the discharging opening, the plurality of filtering holes being formed in a manner such that solid matters existing in the beverage container can be filtered, and the straw insertion hole being perforated to have a predetermined diameter in a manner such that a straw can be inserted through the straw insertion hole and into the discharging opening when the container cover is rotated so as to align the straw insertion hole with the discharging opening, the container cover mounting step comprising:
• fixedly maintaining the container end which is moved, thereby to prevent the container end from fluctuating;
• slantingly lifting the pull tab at a predetermined angle, the pull tab being coupled to the upper end of the fixed container end;
• and
• inserting the container cover between the lifted pull tab and the upper surface of the fixed container end.

A method for mounting a container cover which is mountable to a beverage container, comprising the processes of:

• forming a body of the beverage container, in which a beverage is to be accommodated;
• forming a container end which is to be coupled to an upper end of the body of the beverage container, the container end coupled with a pull tab via a central pin, the pull tab having a lift end capable of being lifted to leverage the pull tab across the central pin and against the container end for opening a discharging part and thereby defining a discharging hole, the discharging hole allowing the beverage to be discharged out of the beverage container therethrough;
• coupling the container end to the upper end of the body of the beverage container in a state wherein the beverage is accommodated in the body of the beverage container;
• forming a container cover comprising a body of substantially a disc-shaped configuration, the body being formed at least with a beverage discharging opening and a straw insertion hole, the body defining a rotation guiding part sized to fit about the central pin;
• forming fluctuation preventing means located on the container cover such that the container cover is maintained in place relative to the container end while the container cover is rotatably coupled to the upper surface of the container end, wherein the fluctuation preventing means comprises a pair of engaging grooves which are formed in the container cover in a manner such that a pair of tab fixing projections which project out of the upper surface of the container end are engaged into the pair of engaging grooves, respectively;
• and
• rotatably coupling the container cover to the central pin between an upper surface of the container end and the pull tab, while the container end forming process is implemented.
