a quantitative dropper comprises a tube body and a quantitative part, wherein the quantitative part is arranged at the top of the tube body and is used for quantitatively sucking liquid and storing the liquid in the tube body; the tube body comprises a first tube body and a second tube body, the upper part of the first tube body is fixedly connected with the quantitative part, the first tube body is a liquid storage tube body, and the tube body part of the first tube body is provided with a gourd-shaped capsule cavity with a plurality of shrinkage joints; the second pipe body is arranged beside the lower part of the first pipe body and is provided with a communicating part communicated with the first pipe body, the second pipe body is a liquid outlet pipe body, the lower part of the second pipe body is provided with a liquid inlet and outlet, and the outer side of the upper part of the liquid inlet and outlet, which corresponds to the pipe body, is provided with an outer convex top block.

As a further limitation, the first pipe body and the second pipe body are arranged in parallel, and the second pipe body is attached to and arranged beside the first pipe body.

By way of further limitation, the dosing member is an elastomeric extrusion head or a piston-type extrusion head.

By way of further limitation, the pipe diameter of the first pipe body is larger than the pipe diameter of the second pipe body.

As a further limitation, the first tube body is provided with scale marks for marking the amount of liquid in the tube.

As a further limitation, the convex jacking blocks are a plurality of triangular jacking blocks arranged on the second pipe body, and the triangular jacking blocks are uniformly arranged on the same height plane of the outer pipe surface of the second pipe body.

Has the advantages that: the utility model relates to a quantitative dropper which can effectively improve the convenience of the quantitative dropper in the using process, and the double-tube structure design of the quantitative dropper is matched with a calabash-shaped sac cavity at the lower part of a first tube body, so that the deformation or damage caused by extrusion in the storing, transporting and using processes can be effectively prevented; the outward convex top block can be propped against the side wall of the container when the quantitative dropper is used, so that the liquid outlet of the dropper liquid inlet and outlet can not touch the side wall of the container and can not directly fall into the container.

FIG. 3 is an enlarged view of the cucurbit-shaped capsular bag of FIG. 1

Wherein: 1. a quantitative member; 2. a first pipe body; 3. a communicating portion; 4. a second tube body; 5. a gourd-shaped capsule cavity; 6. a convex top block; 7. a liquid inlet and outlet.

Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand and understand, the present invention is further explained by combining with the specific drawings.

Referring to fig. 1 to 3, a preferred embodiment of a quantitative dropper includes a tube and a quantitative member 1, in this embodiment, the quantitative member 1 is an elastic extrusion head, while in another embodiment, the quantitative member 1 may also be a piston type extrusion head, and the quantitative member 1 only needs to achieve the effect of absorbing quantitative liquid by using a quantitative negative pressure value.

The lower part of the quantifying component 1 is connected with a first pipe body, the first pipe body 2 is a liquid storage pipe body, a calabash-shaped sac cavity 5 is arranged below the first pipe body 2, and scale marks used for marking the amount of liquid in the first pipe body 2 are arranged on the side wall of the first pipe body 2. In the embodiment, the cucurbit flute 5 has two shrinkage joints, the structure design of the cucurbit flute 5 can be used as a volume cavity on one hand, and on the other hand, the outer diameter of the side wall of the tube body can be reinforced through the shrinkage joint structure, so that the deformation and damage caused by collision and extrusion in the transportation, storage and use processes are improved.
