发明名称 SEALED BAG
摘要 PROBLEM TO BE SOLVED: To make a seal-packaged content in a bag flow out from the flow-out passage little by little even when a part of the bag is pressed by a finger tip or the like, and prevent the content from unpreparedly jetting out energetically by seal-forming a labyrinth which repeats unevennesses in the flowing-out direction on one side or both sides of the flow-out passage. SOLUTION: On this sealed bag 1 in which a content is sealed, a vertical seal 2 and upper and lower lateral seals 3 and 4 are formed. Also the upper lateral seal 3 is formed to be wider than the lower lateral seal 4 under a state wherein a narrow flow-out passage 5 is remained on one side. Then, a labyrinth 5P is seal-formed on one side or both sides of the flow-out passage 5, and for the labyrinth 5P, a plurality of protrusions 5A, 5C and 5E and a plurality of recesses 5B, 5D and 5F are alternately arranged in the flowing-out direction PA of the content respectively. By this constitution, the content which flows in the flowing-out direction PA is brought into contact with respective protrusions 5A, 5C and 5E, and at the same time, one part of the content enters respective recesses 5B and 5D as shown by arrows PB and PD, and the flowing- out pressure of the content is lowered, and the flow-out amount is reduced.
