With continued reference to fig. 10 to 16, the sealing portion 20A is attached to the first bag wall 102A of the bag body 10A so as to seal the outlet 13A of the bag body 10A, so that the sealing portion 20A can seal the outlet 13A of the bag body 10A to prevent the kitchen waste 200A contained in the containing space 11A of the bag body 10A from being discharged from the outlet 13A of the bag body 10A, and the sealing portion 20A can reinforce the strength of the position of the first bag wall 102A of the bag body 10A at the outlet 13A to ensure the reliability of the garbage bag 100A.
Further, the sealing portion 20A includes a sealing surface layer 21A and a glue layer 22A disposed on the sealing surface layer 21A, wherein the sealing portion 20A is attached to the first bag wall 102A of the bag body 10A in a manner that the glue layer 22A glues the sealing surface layer 21A and the first bag wall 102A of the bag body 10A, and the discharge port 13A of the bag body 10A corresponds to the glue layer 22A of the sealing portion 20A, so as to seal the discharge port 13A of the bag body 10A by the sealing portion 20A. When the user applies a force to the sealing surface layer 21A of the sealing portion 20A to tear the sealing portion 20A in a direction away from the bag body 10A, the adhesive layer 22A of the sealing portion 20A can be separated from the first bag wall 102A of the bag body 10A, so that the sealing portion 20A can expose the discharge port 13A of the bag body 10A to allow the kitchen waste 200A contained in the containing space 11A of the bag body 10A to be discharged from the discharge port 13A of the bag body 10A.
It is worth mentioning that the adhesive force of the glue layer 22A and the sealing surface layer 21A is greater than the adhesive force of the glue layer 22A and the first bag wall 102A, so that when the external force applied to the sealing surface layer 21A is greater than the adhesive force of the glue layer 22A and the first bag wall 102A, the glue layer 22A can be torn in the direction away from the bag body 10A to expose the outlet 13A of the bag body 10A.
Preferably, at least one end of the sealing surface layer 21A of the sealing portion 20A is formed with the force application region 211A so that a user can pinch the force application region 211A to apply a force to the sealing surface layer 21A, for example, a thumb and an index finger of the user can pinch the force application region 211A of the sealing surface layer 21A to apply a force to the sealing surface layer 21A to tear the sealing portion 20A in a direction away from the bag body 10A.
It should be noted that the manner in which the end portion of the adhesion surface layer 21A of the adhesion portion 20A forms the biasing region 211A is not limited in the trash bag 100A of the present invention, and for example, the biasing region 211A can be formed in a region where the adhesive layer 22A is not provided on the end portion of the adhesion surface layer 21A. Preferably, an end of the sealing surface layer 21A of the sealing portion 20A for forming the force application area 211A extends to a position of the fold 16A of the bag body 10A, so that when the containing space 11A of the bag body 10A is expanded and deformed by containing the kitchen waste 200A, the force application area 211A of the sealing surface layer 21A can automatically be away from the first bag wall 102A of the bag body 10A, thereby facilitating a user to pinch the force application area 211A of the sealing surface layer 21A to apply force to the sealing surface layer 21A.
With continued reference to fig. 10 to 16, in this specific example of the trash bag 100A of the present invention, one end portion of the sealing surface layer 21A of the sealing portion 20A forms the biasing area 211A, and the other end portion of the sealing surface layer 21A is heat-sealed to the bag body 10A, so that when the sealing portion 20A is exposed to the discharge port 13A of the bag body 10A by biasing the sealing surface layer 21A of the sealing portion 20A, the sealing portion 20A can be prevented from being detached from the bag body 10A and falling into a collection trash can 400A for collecting the kitchen trash 200A, thereby facilitating separation of the trash bag 100A and the kitchen trash 200A.
