Drip Bag

Abstract

To reduce force required for opening in a drip bag configured to open a bag body by pulling sealing members on the front and back of the bag body in opposite directions.SOLUTION: A drip bag 1A comprises a bag body 11, sealing members 20 provided on two facing outer surfaces of the bag body 11, and an extraction material M filling the bag body, where an easy-to-tear line 12 is formed along an upper edge 11a of the bag body 11. Each of the two sealing members 20 includes: an upper-end central part 26 protruding in a tongue-like shape from an upper end of a central part in a body width direction; a pair of sealing parts 21 to be pulled out from the bag body 11, provided on both sides of a width center line of the upper-end central part 26, on a bag body bottom 11c side with respect to the upper-end central part 26; a pair of notches 25 formed on the left and right sides of the upper-end central part 26; and upper reinforcing parts 23 provided adjacent to bag body sides of the notches 25. The width w2 of a non-adhesive area S between an adhesive area R2 of the upper reinforcing part 23 and the upper-end central part 26 is equal to or more than twice the width w1 of the upper-end central part.SELECTED DRAWING: Figure 1
