[0025] See also Figures 1 to 4 A packaging bottle comprises a bottle body 1, a filling port 11 is opened on one side of the bottle body 1, the filling port 11 communicates with the outside and the inner cavity of the bottle body 1, a liquid inlet valve 2 is installed in the filling port 11, and the liquid inlet valve 2 comprises a valve sleeve 21 fixedly installed in the filling port 11, a movable plug 22 that can slide relative to the valve sleeve 21, and an elastic member 23;

[0026] A connecting port 211 is provided at one end of the valve sleeve 21, through which liquid can enter the interior of the valve sleeve 21. An annular flange 212 is provided inside the valve sleeve 21. A liquid inlet 221 is provided at one end of the movable plug 22, and the other end is sealed. The movable plug 22 is a hollow tubular structure, and liquid entering the interior of the valve sleeve 21 can enter the hollow inner cavity of the movable plug 22. The valve sleeve 21 is sleeved on the outside of the movable plug 22, and the liquid inlet end of the movable plug 22 slides between the connecting port 211 of the valve sleeve 21 and the annular flange 212. A protrusion 222 is provided on the outer wall of the liquid inlet end of the movable plug 22. The elastic member 23 is arranged between the protruding member 222 and the annular flange 212. The protruding member 222 abuts against one end of the elastic member 23, and its function is to cooperate with the annular flange 212 to install the elastic member 23. When the protruding member 222 approaches the annular flange 212, the elastic member 23 is compressed; when the protruding member 222 moves away from the annular flange 212, the elastic member 23 stretches; an annular flow-blocking member 223 is sleeved on the outer wall of the sealing end of the movable plug 22, and a liquid outlet 224 communicating with the hollow inner cavity of the movable plug 22 is provided in the middle of the side wall of the movable plug 22 and between the protruding member 222 and the flow-blocking member 223;

[0027] When the elastic member 23 is in a natural state, the flow blocking member 223 abuts against the annular flange 212 to block the liquid from flowing into the bottle body 1 from the liquid outlet hole 224. At this time, the liquid inlet valve 2 is in a closed state. The liquid entering the valve sleeve 21 from the connecting port 211 can only enter the hollow inner cavity of the movable plug 22 from the liquid inlet port 221 of the movable plug 22, but cannot enter the bottle body 1 from the hollow inner cavity of the movable plug 22 through the liquid outlet hole 224. When the elastic member 23 is in a compressed state, the liquid in the valve sleeve 21 can only enter the hollow inner cavity of the movable plug 22 from the liquid inlet port 221 of the movable plug 22. The liquid outlet hole 224 is located between the opposite ends of the annular flange 212 and the connecting port 211 of the valve sleeve 21 so that the liquid can flow into the bottle body 1 from the liquid outlet hole 224. At this time, the liquid inlet valve 2 is in an open state. The liquid entering the valve sleeve 21 from the connecting port 211 first enters the hollow inner cavity of the movable plug 22 from the liquid inlet port 221 of the movable plug 22, and then enters the bottle body 1 from the hollow inner cavity of the movable plug 22 through the liquid outlet hole 224, thereby filling the bottle body 1 with liquid. Therefore, by pressing the movable plug 22, the elastic member 23 is compressed, so that the liquid can pass through the connecting port 211 of the valve sleeve 21, the interior of the valve sleeve 21, the liquid inlet 221 of the movable plug 22 and the hollow inner cavity of the movable plug 22 in sequence, and then flow into the bottle body 1 from the liquid outlet 224 of the movable plug 22; after the filling is completed, loosening the movable plug 22 can make the blocking member 223 abut against the annular flange 212 to prevent the liquid from flowing into the bottle body 1 from the liquid outlet 224, and at the same time play the role of sealing the packaging bottle, realizing the rapid closure of the filling port, thereby avoiding contamination of the liquid contents.

[0028] The setting of the liquid inlet valve in the present application enables the packaging bottle to quickly open the liquid inlet valve for filling by compressing the movable plug 22, and quickly close the filling port by loosening the movable plug 22. The packaging bottle is provided with a bottle mouth 12, and the bottle mouth 12 or the filling port 11 can be selected for filling during filling. When the filling port 11 is selected for filling, the bottle mouth 11 is covered with a bottle cap before filling (the bottle cap is not shown). In actual application, the liquid inlet valve 2 can be opened by inserting the filling nozzle of the filling device (the filling device is not shown in the figure) into the communication port 211 of the liquid inlet valve 2 of the packaging bottle so that the movable plug 22 is compressed.

[0029] In this embodiment, the protrusion 222 is a convex portion extending outwardly along the diameter direction on the outer wall of the liquid inlet end of the movable plug 22, and the convex portion is annular. In some other embodiments, the protrusion 222 adopts a rectangular convex strip structure to abut the elastic member 23, as long as it can abut one end of the elastic member 23.

[0030] Preferably, an annular groove 225 is provided on the outer wall of the sealing end of the movable plug 22, and the flow blocking member 223 is installed in the groove 225. The groove 225 facilitates the installation of the flow blocking member 223, and the flow blocking member 223 can be conveniently sleeved on the outer wall of the sealing end of the movable plug 22, and the flow blocking member 223 can be prevented from sliding relative to the movable plug 22.

[0031] Preferably, the baffle 223 is a sealing ring, which can be in close contact with the annular flange 212 when the elastic member 23 is in a natural state, thereby preventing the liquid from flowing into the bottle body from the gap between the sealing ring and the annular flange 212. In addition, the sealing ring has a buffering effect, thereby preventing the annular flange 212 and the baffle 223 from making hard contact when the elastic member 23 rebounds, thereby preventing damage to the annular flange 212 and / or the baffle 223.

[0032] Preferably, a plurality of liquid outlet holes 224 are provided, and the plurality of liquid outlet holes 224 are evenly distributed on the outer wall of the movable plug 22. In this embodiment, two liquid outlet holes 224 are provided, and the provision of a plurality of liquid outlet holes 224 enables a faster liquid outlet speed than that of a single liquid outlet hole 224. Of course, the number of liquid outlet holes 224 may be three or more.

[0033] In this embodiment, the liquid outlet holes 224 are in the shape of long rectangles and are evenly distributed on the outer wall of the movable plug 22. Of course, the liquid outlet holes 224 can also be in other shapes such as circular, elliptical, star-shaped, heart-shaped, etc.

[0034] In this embodiment, the elastic member 23 is a spring, and the spring is sleeved on the outer wall of the movable plug 22. Of course, the elastic member 23 can be a spring sheet, and the two ends of the spring sheet abut against the protruding member 222 and the annular flange 212 respectively.

[0035] Preferably, the outer wall of the valve sleeve 21 at one end of the communication port 211 thereof extends outwardly in the diameter direction to form a limiting portion 213, and the limiting portion 213 abuts against the surface of the bottle body 1 at the location of the filling port 11. When installing the valve sleeve 21, the valve sleeve 21 is inserted into the filling port 11 until the limiting portion 213 abuts against the surface of the bottle body 1 at the location of the filling port 11, and the limiting portion 213 serves to remind the valve sleeve 21 to be installed in place. Preferably, the valve sleeve 21 is interference fit or threadedly connected in the filling port 11 to achieve the fixing of the valve sleeve 21.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
