Along the joined longitudinal strips (6), suitable welding lines (7, 8) are made so as to form a portion (9) in the form of a channel compartment (10) that is closed at one end, and having its other end in communication with an inside of the package. A a longitudinal breaking line (12) is made in the strips to allow the portion (9) to be partially detached from the package. In the strips (6) a notch (13) is made which allows the detachable portion (9) to be opened at the end opposite to the one in communication with the inside of the package (1).Field of SearchDISPENSING FEATUREPRODUCT WITH DRINKING TUBE For dispensing or serving Having destructive type opening along scored or perforated line Having destructive type opening utilizing tearing appendage Nonmetallic About line or point of weakness Having reusable closure Forming a cover adjunct or application of a cover adjunct to a cover Package opening device (e.g., tear strip) Making a pocket in web material by folding and side sealing (e.g., flat bag making) Of preformed nonfreestanding container deformed by contents (e.g., bag, tube) By collapsing mouth portion (e.g., to form single flap) Adjunct comprising provision to allow access to contents, e.g., spout, straw, drain, opening, etc. Fitment to dispense flowable contents, e.g., spout | |
