Plastic bag and carrier handle |
摘要 |
A plastic bag of flat, frusto-conical form has an open upper end formed to receive a filling nozzle and to serve as a funnel when the bag is being emptied, and a carrier handle has three arms for receiving the upper end of the bag with the bag forming a loop which extends about a first handle arm and is frictionally locked on a second arm, a third arm preventing leakage or back surge from the bag, and the narrower open end of the mouth of the bag being fully sealed by a wider lower portion of the bag mouth.
