[0025] The utility model will be explained in further detail below in combination with the drawings and specific embodiments.

[0026] Referring to the drawings Figure 1 to the drawings Figure 2 As shown in the drawings, the embodiment provides a flour packaging bag 10, which comprises a packaging bag body 100, a flour outlet nozzle 200 and a cap 300.

[0027] The packaging bag body 100 preferably adopts a flat shape, which can save design space and facilitate transportation. A handle hole 101 for facilitating consumers to hold is formed at the upper end of the packaging bag body 100.

[0028] The inner wall of the packaging bag body 100 can be sewn with a moisture-proof layer, which can be made of aluminum foil or coated material. The moisture-proof layer can improve the moisture-proof performance of the flour packaging bag 10 and extend the shelf life of the flour.

[0029] The flour outlet nozzle 200 is fixedly installed on the packaging bag body 100. In some embodiments, in order to facilitate the pouring of flour, the flour outlet nozzle 200 is preferably arranged at the top end or the bottom end of the packaging bag body 10. Preferably, the flour outlet nozzle 200 is installed at the side surface of the top end of the packaging bag body 100. In this way, when the flour is poured out, the packaging bag body 100 is tilted and lifted upwards, so that one side of the flour outlet nozzle 200 is tilted downwards. The flour in the packaging bag body 100 can be concentrated at one side of the flour outlet nozzle 200 under the action of gravity, and the flour in the packaging bag body 100 can fall out of the flour outlet nozzle 200.

[0030] The flour outlet nozzle 200 is a pipeline structure with two ends penetrating each other. The inner end of the flour outlet nozzle 200 is fixed on the inner wall of the packaging bag body 100 and is connected with the inner cavity of the packaging bag body 100. The outer end of the flour outlet nozzle 200 extends outward from the outer surface of the packaging bag body 100 by a certain length.

[0031] Referring to the drawings Figure 2 and the drawings Figure 4As shown, the bottom end outer peripheral surface of the powder outlet nozzle 200 is fixed with an inner connecting part 201, the outer peripheral surface of the inner connecting part 201 is at least partially provided with a plurality of outer ratchet teeth 202 arranged along the circumferential direction, the plurality of outer ratchet teeth 202 are arranged along the same direction, for example, uniformly in the clockwise direction or uniformly in the counterclockwise direction. In this embodiment, the entire outer peripheral surface of the inner connecting part 201 is provided with the outer ratchet teeth 202 arranged along the circumferential direction, which can ensure the stability of the connection between the inner connecting part 201 and the cap 300.

[0032] Referring to the accompanying drawings Figure 1 to the accompanying drawings Figure 4 As shown, the bottom end of the cap 300 is provided with a connecting band 301, the connecting band 301 comprises a band-shaped connecting band body, the connecting band body is made of elastic material, for example, the connecting band body is made of rubber material, so that the connecting band body can be conveniently wound around the outer periphery of the inner connecting part 201, and the connecting band body has opposite open ends 303 and a fixed end 302. The fixed end 302 is fixedly installed on the outer edge bottom of the cap 300, and the open end 303 is wound on the outer surface of the inner connecting part 201 and is detachably fixedly installed on the outer surface of the connecting band body, and the inner wall of the connecting band body is provided with inner ratchet teeth 305 engaged with the outer ratchet teeth 202.

[0033] Referring to the accompanying drawings Figure 2 and the accompanying drawings Figure 4 As shown, the outer surface of the powder outlet nozzle 200 is provided with external threads, the external threads are arranged above the inner connecting part 201, and the inner wall of the cap 300 is provided with internal threads, the cap 300 is engaged on the external threads of the powder outlet nozzle 200 through the internal threads thereon, so that the cap 300 can be fixedly installed on the powder outlet nozzle 200.

[0034] Referring to the accompanying drawings Figure 3 As shown, the open end 303 is fixed with a plug 306, and the connecting band body is provided with a pin hole 307 engaged with the plug 306, that is, the open end 303 is fixed on the connecting band body by inserting the plug 306 into the pin hole 307.

[0035] Referring to the accompanying drawings Figure 1 and the accompanying drawings Figure 3As shown, the outer surface of the connecting band body has a connecting groove for the insertion of the open end 303. The connecting groove is arranged such that, after the open end 303 is inserted into the connecting groove, the outer groove wall of the connecting groove can limit the open end 303, thereby playing a restraining function on the open end 303, preventing the open end 303 from moving outward (i.e., in the radial direction of the inner connecting part 201) and causing the plug 306 to disengage from the insertion hole. In addition, in order to facilitate the insertion of the open end into the connecting groove, the open end 303 has a guide portion 304 for insertion into the connecting groove. The guide portion 304 is formed by forming a beveled cut on both the upper and lower sides of the open end, so that the width dimension of the position on the connecting band body adjacent to the open end gradually decreases, thereby facilitating the insertion of the open end into the connecting groove. Referring back to Fig. 1, the outer surface of the connecting band body has a plurality of insertion holes 309 for the insertion of the plug 306. The insertion holes 309 are arranged in a staggered manner on the outer surface of the connecting band body, and the insertion holes 309 are arranged in a staggered manner on the outer surface of the connecting band body. The insertion holes 309 are arranged in a staggered manner on the outer surface of the connecting band body, and the insertion holes 309 are arranged in a staggered manner on the outer surface of the connecting band body. Figure 3 As shown, the inner wall of the connecting band body adjacent to the open end 303 is provided with a receiving groove 308 for receiving the fixed end 302.

[0036] Referring back to Fig. 1, the outer surface of the connecting band body has a plurality of insertion holes 309 for the insertion of the plug 306. The insertion holes 309 are arranged in a staggered manner on the outer surface of the connecting band body, and the insertion holes 309 are arranged in a staggered manner on the outer surface of the connecting band body. Figure 1 As shown, after the cap 300 is screwed onto the powder outlet nozzle 200, the open end of the connecting band at the bottom end of the cap 300 is wrapped around the outer periphery of the inner connecting part 201 for one turn and then fixed on the connecting band body, and the inner ratchet teeth 305 on the inner wall of the connecting band body are engaged with the outer ratchet teeth 202 on the outer periphery of the inner connecting part 201, so that the cap 300 cannot be rotated and disengaged from the powder outlet nozzle 200, thereby playing a child lock function to prevent children from easily opening the cap 300.

[0037] When the cap needs to be opened, the plug 306 is first pulled out of the insertion hole 307, then the connecting band body is separated from the inner connecting part 201, i.e., the inner ratchet teeth 305 on the connecting band body are disengaged from the outer ratchet teeth 202 on the inner connecting part 201, and finally the cap 300 is rotated to disengage the cap 300 from the powder outlet nozzle 200, so that the outer end of the powder outlet nozzle 200 is exposed, and the flour in the packaging bag body can be poured out through the powder outlet nozzle 200; after the flour pouring operation is completed, the cap 300 is screwed back on, and the open end of the connecting band is wrapped around the outer periphery of the inner connecting part 201 for one turn and then fixed on the connecting band body.

[0038] Obviously, those skilled in the art can make various modifications and variations to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and equivalent technology, the present application also intends to include these modifications and variations.
