as shown in fig. 1-4, the sealed moisture-proof quantitative material taking bottle cap comprises a bottle cap 1 matched with a bottle body, wherein a material outlet 101 is arranged on the bottle cap 1, and the sealed moisture-proof quantitative material taking bottle cap further comprises a quantitative material taking mechanism 2 connected with the bottle cap 1 in a sliding manner, wherein the quantitative material taking mechanism 2 changes the relative position with the bottle cap 1 through sliding to realize one-off blocking or communication between the material outlet 101 and the bottle body; the top surface of the bottle cap 1 is hinged with a sealing element 3 for sealing the discharge hole 101, the sealing element 3 and the bottle cap 1 are respectively provided with a first suction element 301 and a second suction element 102 which can be mutually sucked, the second suction element 102 is positioned on the outer side of the sealing element 3 and close to the connection part of the bottle cap 1 and the sealing element 3, and when the sealing element 3 is in an opening state, the first suction element 301 and the second suction element 102 are sucked; the outer circumference of the sealing member 3 is sealed in line contact with the bottle cap 1.

Fig. 2 shows an initial state of the bottle cap 1 after the bottle cap 1 is mounted on the bottle body. At this time, the sealing member 3 blocks the discharge port 101, and at this time, the quantitative material taking mechanism 2 is communicated with the bottle body and blocks the discharge port 101. When the object in the bottle needs to be poured out, the bottle is turned over, the sealing element 3 naturally rotates under the action of gravity to expose the discharge hole, the object in the bottle falls into the containing cavity formed by the quantitative material taking mechanism 2 and the bottle cap 1, then the quantitative material taking mechanism 2 is moved, and when the quantitative material taking mechanism 2 is communicated with the discharge hole, the object is poured out from the containing cavity.

The third suction element 103 is additionally provided in this embodiment to ensure that the sealing element 3 is sucked with the cap 1 in the closed state. However, the sealing member 3 cannot be rotated naturally by gravity as in embodiment 1 due to the third suction member 103, and the user is required to separate the sealing member 3 from the bottle cap 1, and after separation, the sealing member 3 can still be rotated by gravity in a direction to attract the first suction member 301 and the second suction member 102 due to the limited attraction of the third suction member 103 to the first suction member 301.

In order to facilitate the separation of the closure 3 from the cap 1 by the user applying a force to the closure 3, a toggle portion is provided on the closure 3. The dial portion allows a user to apply a force to the sealing member 3 in the axial direction of the sealing member 3 or in the normal direction of the rotation of the sealing member 3, and thus, the dial portion is preferably provided in the form of a protrusion on the upper surface of the sealing member 3. More preferably, according to the lever principle, the preferred setting position of the toggle part is the diameter of the point passing through the joint of the sealing member 3 and the bottle cap 1, and the toggle part can be set at any point on the diameter, wherein the point farthest from the joint is the most preferred.

Example 3:

this embodiment further optimizes and defines the first suction member 301, the second suction member 102, and the third suction member 103 on the basis of embodiment 2.

The attraction between the magnet and iron, cobalt and nickel and the attraction between magnets with different magnetic poles are used to achieve the attraction. When the first attraction piece 301 is a magnet, the second attraction piece 102 and the third attraction piece 103 may be any one of a metal piece or a magnet with a magnetic pole different from that of the first attraction piece 301, where the metal piece is worth of a metal capable of being attracted by the magnet, and the metal piece is a mixture with any one or more of iron, cobalt and nickel as a main component or a whole component according to common knowledge.

The projection not only limits the limit position of the rotation of the sealing member 3, but also the second suction member 102 and the first suction member 301 in the sealing member 3 attract each other, so that the sealing member 3 is kept in the state of attracting with the projection.

It should be noted that the protrusion is provided to limit the limit position of the sealing member 3 and keep the sealing member 3 in a relatively upright position, and the protrusion may be provided on the sealing member, and at this time, the first suction member 301 needs to extend into the protrusion, so that when the sealing member 3 rotates to a position where the protrusion contacts with the bottle cap, the first suction member 301 is attracted to the third suction member 103.

Example 5:

the present embodiment is further optimized and defined based on the above embodiments.

The sealing ring or the sealing cover layer does not exceed the bottom area of the sealing element 3, the bottom surface of the sealing ring or the sealing cover layer is smaller than or equal to the height between the bottom surface of the sealing element 3 and the top surface of the bottle cap 1, namely the arrangement of the sealing ring and the sealing cover layer does not interfere the line contact between the sealing element 3 and the bottle cap 1, the arrangement of the sealing ring or the sealing cover layer can further prevent moisture in the air from entering the bottle body, and even if the line contact is not tight, because the contact area between the sealing ring or the sealing cover layer and the air is increased, water vapor in the air is adsorbed on the sealing ring or the.

Example 6:

the embodiment provides a specific structure of the bottle cap 1 and the quantitative material taking mechanism 2 on the basis of the above embodiments.

As shown in fig. 5 to 6, a damping buffer member for increasing the resistance between the bottle cap 1 and the quantitative material taking mechanism 2 is arranged between the contact surfaces of the bottle cap 1 and the quantitative material taking mechanism 2. A spring 105 with the axis parallel to the movement direction of the quantitative material taking mechanism 2 is arranged between the quantitative material taking mechanism 2 and the bottle cap 1, and the spring 105 drives the quantitative material taking mechanism 2 to block the discharge hole 101. The bottle cap 1 comprises a lower cover connected with a bottle body and an upper cover clamped on the lower cover, the lower cover is provided with a feed inlet 104, and the feed inlet 104 and the discharge outlet 101 are arranged in a staggered manner; the quantitative material taking mechanism 2 is provided with a channel 201, and when one end of the channel 201 is aligned and communicated with the feed inlet 104, the other end of the channel 201 is blocked by the upper cover; when one end of the channel 201 is completely communicated with the discharge hole 101, the lower cover blocks the other end of the channel 201; when the quantitative material taking mechanism 2 is located at another position, the inlet 104 and the outlet 101 form a communicating mechanism or a blocking structure through the passage 201.

The working principle is as follows:

during one-hand operation, it is more convenient than pulling spring 105 to press down spring 105, therefore, the utility model discloses an optimal scheme is, when quantitative material taking mechanism 2 and bottle intercommunication, spring 105 is in the natural stretching state, this is quantitative material taking mechanism 2's initial position, when needs are got the material, overturn the bottle earlier, make the object fall into the cavity that the passageway 201 of quantitative material taking mechanism 2 and the upper cover of bottle lid 1 constitute, then press quantitative material taking mechanism 2, spring 105 is compressed, the passageway 201 and the discharge gate 101 intercommunication of quantitative material taking mechanism 2, the object falls out from the cavity that passageway 201 and lower cover constitute, after the hand is loosened, quantitative material taking mechanism 2 moves to initial position under spring 105's effect.

It should be noted that when the spring 105 is pressed, the damping buffer increases the resistance when pressing, so that the quantitative material taking mechanism 2 moves at a relatively uniform speed, and the impact force between the quantitative material taking mechanism 2 and the bottle cap 1 caused by excessive force when pressing can be reduced. When the spring 105 returns to its original length, the damping cushion also moves the dosing mechanism 2 to the initial position at a relatively uniform speed, and the elastic force of the return spring 105 causes an acceleration of the movement of the dosing mechanism 2 when acting on the dosing mechanism 2.

In addition, the damping bolster can also play the effect of reinforcing leakproofness, and is concrete, and quantitative feeding agencies 2 and bottle lid 1 between each other sliding fit certainly have the gap between the two, like the granule that the diameter is less like salt gets into the gap easily and blocks in the gap, hinders quantitative feeding agencies 2 and slides, perhaps moves outside the bottle through the gap. And the damping buffer piece is equivalent to a sealing strip arranged between the quantitative material taking mechanism 2 and the bottle cap 1.

It is worth mentioning that the single dose depends on the size of the cavity formed between the passage 201 of the dosing and extracting mechanism 2 and the closure 1.

The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
