  • Publication number: 20080093429
    Abstract: The present invention relates to a disposable container of liquid food products or a cap thereof, having two independent round straw holes to be inserted by two ends of one bent drinking tube, the diameters of the said straw holes tightly match the diameters of said drinking tube at its two ends, so that the drinking tube can be inserted and pulled repeatedly. When temporarily halting drinking, the consumer can insert the two ends of the bent drinking tube into the two straw holes for closing the container, therefore preventing contamination of ends of the drinking tube, and leaking of the liquid. When subsequently drinking the liquid inside, the consumer just need to pull out one end of the drinking tube and keeping the other end of the drinking tube remaining inserted in one straw hole. The other straw hole serves the purpose of allowing air into the container for easy access of the liquid.
