[0030] As Figure 1 and Figure 2As shown, the quantitative discharging cover according to the first aspect of the present application comprises a first cover body 100, a second cover body 200 and a rotating body 300, which are all injection molded in this embodiment, having the advantages of low cost, stable structure, corrosion resistance and the like, and are very suitable for use in the packaging industry. The first cover body 100 can be cylindrical in structure, and is provided with a quantitative cavity 110 therein. One end face of the first cover body 100 is closed, and the other end face is open 120 and is provided with a first connecting part 121, such as a thread, a buckle or the like. Correspondingly, the second cover body 200 can be ring-shaped, and is provided with an internal thread 210 for threadedly connecting with the bottle mouth 11 of the bottle body 10, and is also provided with a second connecting part 220 for matching connection with the first connecting part 121, so that the second cover body 200 can be connected to the open 120 of the first cover body 100. Since the second cover body 200 can be ring-shaped, a boss 230 can be provided in the circular hole thereof, and the middle part of the boss 230 is provided with a feeding passage 231. When the second cover body 200 is threadedly connected to the bottle mouth 11 of the bottle body 10, the feeding passage 231 is in communication with the inside of the bottle body 10, so that the contents in the bottle body 10 can flow into the quantitative cavity 110 of the first cover body 100 through the feeding passage 231.

[0031] In order to realize quantitative discharging, two hole positions are provided on the peripheral surface of the first cover body 100, and the two hole positions are linearly distributed to jointly form a mounting hole 101 penetrating through the first cover body 100, and the axis of the mounting hole 101 is orthogonal to the axis of the feeding passage 231. Specifically, the first cover body 100 extends outwardly at the two hole positions to form an upper protruding position 130 and a lower protruding position 140, and the upper protruding position 130 and the lower protruding position 140 still retain holes to be rotationally connected with the rotating body 300. At this time, the rotating body 300 is provided with a first clamping position 310 on each side thereof, and the upper protruding position 130 and the lower protruding position 140 are both provided with a second clamping position 102 for clamping with the first clamping position 310, so as to limit the relative position of the rotating body 300 in the first cover body 100 and meet the rotation requirement of the rotating body 300.

[0032] As shown in FIG. 1, the quantitative discharging cover according to the first aspect of the present application is provided with a bottle body 10, and the bottle body 10 is provided with a bottle mouth 11. The quantitative discharging cover is connected to the bottle mouth 11 of the bottle body 10, and the quantitative cavity 110 of the first cover body 100 is in communication with the inside of the bottle body 10 through the feeding passage 231 of the second cover body 200, so that the contents in the bottle body 10 can flow into the quantitative cavity 110 of the first cover body 100 through the feeding passage 231. Figure 2 and Figure 3As shown, the rotating body 300 has a cylindrical surface, which is provided with a discharging passage 320 at a position corresponding to the lower convex position 140. The rotating body 300 is provided with a flow guide hole 321 and a discharging hole 322, which are respectively communicated with the discharging passage 320. The flow guide hole 321 is arranged on the cylindrical surface of the rotating body 300, and the discharging hole 322 is an outlet of the discharging passage 320, which is kept in communication with the outside. At the same time, the rotating body 300 is provided with a rotating position 330 at a position corresponding to the upper convex position 130, so that the user can rotate the rotating body 300 through the rotating position 330. The rotating position 330 includes but is not limited to a tooth slot, a handle, a knob and the like, as long as the rotating position 330 can facilitate the user to rotate the rotating body 300, no matter what structure the rotating position 330 is, which belongs to the protection scope of the present application.

[0033] Correspondingly, the first cover body 100 is provided with a sealing portion 150 beside the lower hole position of the metering cavity 110, which is higher than the corresponding hole position. The sealing portion 150 has a first arc-shaped structure matched with the rotating body 300. The flow guide hole 321 has a moving path closed by the sealing portion 150, so that the sealing portion 150 can close the flow guide hole 321 of the rotating body 300 to prevent the metering cavity 110 from being communicated with the discharging passage 320. As shown, Figure 4 When the rotating body 300 is rotated to the open position, the flow guide hole 321 is away from the sealing portion 150 with the rotation of the rotating body 300, so as to realize the communication between the metering cavity 110 and the discharging passage 320.

[0034] In addition, the cylindrical surface of the rotating body 300 is provided with a flow guide groove 340 which is not communicated with the discharging passage 320. Correspondingly, the feeding passage 231 has a second arc-shaped structure matched with the rotating body 300. The flow guide groove 340 has a moving path through the feeding passage 231. As shown, Figure 3 When the rotating body 300 is rotated to the closed position, the flow guide groove 340 is corresponding to the feeding passage 231 with the rotation of the rotating body 300, so as to realize the communication between the metering cavity 110 and the feeding passage 231; as shown, Figure 4 When the rotating body 300 is rotated to the open position, the flow guide groove 340 is away from the feeding passage 231 with the rotation of the rotating body 300, instead, the cylindrical surface of the rotating body 300 closes the feeding passage 231, so as to prevent the metering cavity 110 from being communicated with the feeding passage 231.

[0035] In summary, the feeding passage 231 and the dosing cavity 110 are communicated or closed by the rotation of the flow guide groove 340, the discharging passage 320 and the dosing cavity 110 are communicated or closed by the rotation of the flow guide hole 321, and the feeding passage 231 and the discharging passage 320 are alternately communicated with the dosing cavity 110, i.e. when the rotating body 300 is in the closed position, the feeding passage 231 is communicated with the dosing cavity 110 and the discharging passage 320 is not communicated with the dosing cavity 110, and when the rotating body 300 is in the opened position, the discharging passage 320 is communicated with the dosing cavity 110 and the feeding passage 231 is not communicated with the dosing cavity 110.

[0036] With the above structure, the dosing discharging cover 30 of the present application is used to be installed at the bottom of the bottle body 10, at this time, the feeding passage 231 is communicated with the inside of the bottle body 10, when the rotating body 300 is executed to be in the closed position, at this time, the flow guide groove 340 is rotated to correspond to the feeding passage 231, so that the content in the bottle body 10 can flow into the dosing cavity 110 through the feeding passage 231 and the flow guide groove 340 in turn, at the same time, the flow guide hole 321 is rotated to correspond to the sealing part 150, so that the content in the dosing cavity 110 cannot flow out to the outside through the flow guide hole 321, thereby storing the content in the bottle body 10 into the dosing cavity 110. When the rotating body 300 is executed to be in the opened position, at this time, the flow guide hole 321 is rotated to be away from the sealing part 150, so that the content in the dosing cavity 110 can flow out to the outside through the flow guide hole 321 and the discharging passage 320 in turn, at the same time, the flow guide groove 340 is rotated to be away from the feeding passage 231, at this time, the feeding passage 231 is closed by the rotating body 300, so that the content in the bottle body 10 cannot flow into the dosing cavity 110, thereby discharging the content in the dosing cavity 110 to the outside.

[0037] As Figure 2As shown in the drawings, in some embodiments of the present application, since the first cover 100 needs to be connected with the second cover 200, the sealing portion 150 is generally not arranged close to the second cover 200, but preferably arranged away from the second cover 200, so as to ensure that the feeding passage 231 and the discharging passage 320 can be alternately communicated with the metering cavity 110 respectively, the flow guide groove 340 and the flow guide hole 321 of the rotating body 300 are located at different positions of the rotating body 300 respectively. However, the present application does not limit the specific position of the sealing portion 150 in the first cover 100, and in other embodiments, the sealing portion 150 can also be arranged at different positions in the first cover 100, and correspondingly, the relative positions between the flow guide groove 340 and the flow guide hole 321 are also adapted accordingly.

[0038] As shown in the drawings, Figure 1 and Figure 2 As shown in the drawings, in some embodiments of the present application, the rotating position 330 of the rotating body 300 can be a knob, and the maximum size of the knob is greater than the size of the upper convex position 130, so that the knob can be clamped on the upper surface of the upper convex position 130. In order to limit the rotation angle of the knob and avoid excessive operation by the user, the upper convex position 130 is provided with a limiting structure for limiting rotation of the rotating position 330. Specifically, the limiting structure includes two limiting blocks 131, which are respectively located at the first quadrant position and the third quadrant position of the upper convex position 130, or the first quadrant position and the third quadrant position of the upper convex position 130, and the limiting blocks 131 are higher than the knob and are used for limiting the knob, so that the rotation angle of the knob is limited to between 0-90°, so as to meet the technical requirement that the rotating body 300 is switched from the closed position to the open position.

[0039] In other embodiments, the limiting structure includes a limiting groove (not shown in the drawings) arranged on the inner wall of the upper convex position 130, and the rotating body is provided with a sliding edge (not shown in the drawings) slidingly connected with the limiting groove, so as to achieve limiting rotation of the rotating body. It can be understood that the present application does not limit the specific arrangement of the limiting structure, as long as it can achieve limiting rotation of the rotating body 300, regardless of the structure of the limiting structure, which belongs to the protection scope of the present application.

[0040] Further, in order to facilitate the user to identify the position of the rotating body 300, the upper convex position 130 is provided with two marks (not shown in the drawings) corresponding to the rotating position 330, such as "closed" and "open", and the positions of the two marks correspond to the positions of the rotating body 300 in the closed position and the open position respectively.

[0041] As Figure 3 and Figure 4 shown, the liquid container according to the second aspect of the application comprises the dosing cover 30 according to the first aspect of the application, and further comprises a bottle body 10, the top and bottom of which are provided with bottle mouths 11, wherein the bottle mouth 11 at the top of the bottle body 10 is connected with a common bottle cap 20, and the bottle mouth 11 at the bottom of the bottle body 10 is connected with the dosing cover 30, at this time the second cover body 200 is screwed on the bottle mouth 11 at the bottom of the bottle body 10, and the feeding channel 231 is in communication with the inside of the bottle body 10, so that the contents in the bottle body 10 can flow into the feeding channel 231. At the same time, the first cover body 100 is externally arranged on the bottle body 10, at this time the rotating position 330 of the rotating body 300 faces upward, and the discharging hole 322 of the rotating body 300 faces downward, so as to facilitate the user to rotate the rotating position 330 of the rotating body 300.

[0042] When the liquid container according to the application stores laundry detergent, at this time the liquid container is used as a laundry detergent bottle, which is mainly used for a drum washing machine. In actual use, the laundry detergent bottle is placed on the top of the drum washing machine, and the discharging hole 322 thereof is aligned with the laundry detergent storage area of the drum washing machine, so that when the user switches the rotating body 300 from the closed position to the open position, the laundry detergent in the dosing cavity 110 can be discharged into the laundry detergent storage area of the drum washing machine through the discharging hole 322; when the user switches the rotating body 300 from the open position to the closed position, the discharging of the laundry detergent is paused, and instead the dosing cavity 110 is gradually filled with laundry detergent for the next dosing.

[0043] Since the liquid container adopts all the technical solutions of the above-mentioned embodiments, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here.

[0044] The embodiments of the application are described in detail above in combination with the drawings, but the application is not limited to the above-mentioned embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the spirit of the application.
