Therefore, it is urgent to propose a packaging container product which can accurately and quantitatively outlet liquid, does not cause secondary pollution and waste, and can be directly recycled in an environmentally friendly manner after use.

[0042] The utility model provides a quantitative liquid outlet container.

[0043] Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 5 In an embodiment of the utility model, the quantitative liquid outlet container 100 comprises:

[0044] The bottle body 1 is internally formed with a cavity for storing the content liquid;

[0045] The bottle cap 2 comprises an upper cap 21 and a lower cap 22 hinged to the upper cap 21, the lower cap 22 is threadedly connected with the bottle body 1, and the lower cap 22 is provided with a liquid outlet hole 221;

[0046] The inner plug 3 is arranged between the bottle cap 2 and the bottle body 1, and the side of the inner plug 3 facing the liquid outlet hole 221 is provided with an upper convex ring 31, the upper convex ring 31 is in interference fit with the lower cover 22 to form a liquid storage space 30, the upper convex ring 31 is provided with a liquid outlet groove 311 communicating with the inside of the upper convex ring 31, and the space in the liquid storage space 30 below the liquid outlet groove 311 is a constant volume space 301.

[0047] The suction pipe 4 is arranged in the cavity, one end of the suction pipe 4 is connected with the inner plug 3, the other end of the suction pipe 4 is located at the bottom of the bottle body 1 and communicates with the cavity, and the suction pipe 4 communicates with the liquid storage space 30 through the upper convex ring 31.

Figure 7 And Figure 8 Suppose that the capacity of the liquid in the liquid storage space 30 is A, and the liquid outlet groove 311 is arranged at the end of the upper convex ring 31, when an external force is applied to the bottle body 1 (i.e. when the bottle body 1 is squeezed), the content liquid will fill the liquid storage space 30 through the suction pipe 4 and the internal channel of the inner plug 3 under the action of the force, when the external force is removed (i.e. when the bottle body 1 is released and not squeezed), the content liquid above the liquid outlet groove 311 of the inner plug 3 will flow back to the bottle body 1 through the liquid outlet groove 311 under the action of its own gravity, and the space below the liquid outlet groove 311 forms the constant volume space 301, at this time, the content liquid in the constant volume space 301 forms a capacity B, and the content liquid with the capacity B flows out through the liquid outlet hole 221 in the lower cover 22, so that the purpose of constant volume liquid outlet is achieved, the purity of the content liquid in the bottle body 1 is effectively ensured, and the waste of the content liquid is avoided.

[0049] Specifically, the structure of the inner plug 3 is not limited, for example, a hollow structure such as a cylinder, as long as it is arranged between the bottle cap 2 and the bottle body 1, can seal the bottle body 1, and form a liquid storage space 30 with the cap body. Of course, the shape of the liquid outlet groove 311 is not limited, for example, it can be a through hole groove or a columnar groove. It should be noted that the type of the straw 4 is not limited, as long as it is a hollow structure that can suck the content liquid. In addition, the bottle cap 2 can be a folding cap or a single cap. It is worth mentioning that the size of the capacity A and the capacity B can be customized according to the actual quantitative demand. Understandably, the capacity A is greater than the capacity B, which ensures that the liquid in the quantitative space 301 is full, thereby meeting the demand of quantitative liquid outlet. Further, the capacity A is greater than twice the capacity B, which ensures that the capacity B is full.
