The utility model is provided with the spring tube-shaped extrusion cavity at the bottom of the body of the dropping liquid bottle, when the medicine needs to be taken, the dropping liquid bottle is inverted, the extrusion cavity is pressed by fingers, the liquid in the extrusion cavity is extruded out, one time of pressing is carried out, one drop of liquid is extruded out, and the extrusion amount can be accurately controlled; because the shape of extrusion cavity is the spring pipe shape for the extrusion cavity resets more easily, and after the finger loosened the extrusion cavity, the extrusion cavity automatic re-setting.

Description

Quantitative dropping bottle

Technical Field

The utility model relates to a liquid drop bottle especially relates to a ration liquid drop bottle.

Background

The prior dropping liquid medicine bottle, such as an eye drop bottle, mostly adopts a plastic bottle, comprises a plastic bottle body and a dropping nozzle, when in use, the bottle body is squeezed by hands, and the liquid medicine drops out from the dropping nozzle. When people need to use the drops, the people generally need to drop the drops to a required position at a time, the force for squeezing the bottle body by hands is required to be controlled, when the force is too strong, the drops extruded at a time are too much, the waste of the drops is caused, when the force is too small, the drops cannot be extruded or the extrusion amount is too little, the people need to extrude the bottles again, and the use is very inconvenient.

SUMMERY OF THE UTILITY MODEL

The utility model provides a overcome prior art drawback, provide a ration dropping liquid bottle, set up the cavity with the spring tube shape of bottle UNICOM in the bottom of dropping liquid bottle, the cavity is pressed to the staff, and a drop is extruded to disposable ration, and the quantity is controllable, convenient to use.

The utility model provides a technical scheme that its technical problem adopted is:

the quantitative liquid drop bottle comprises a bottle body, a dropping nozzle, a bottle cap and a bottle neck, wherein the bottle neck and the bottle body are integrally arranged, the dropping nozzle is arranged at a liquid outlet of the bottle neck, the bottle cap is in threaded connection with the outer wall of the bottle neck, a groove is formed in the center of the bottom of the bottle body, an extrusion cavity is formed in the bottom wall of the groove, and the extrusion cavity is in a spring tube shape and is communicated with the inner cavity of the bottle body.

In the quantitative liquid drop bottle, the maximum variable volume of the extrusion cavity is more than one time and less than two times of the volume of one drop of liquid.

In the quantitative liquid drop bottle, the maximum variable volume of the extrusion cavity is 1.2-1.5 times of the volume of one drop of liquid.

In the quantitative dropping bottle, the height of the extrusion cavity is lower than or equal to the height of the groove wall at the bottom of the bottle body.

In the quantitative dropping bottle, the extrusion cavity and the bottle body are integrally formed.

In the quantitative liquid drop bottle, the inner wall of the top of the bottle cap is provided with the sealing bulge which is arranged in the liquid outlet of the drip nozzle and is matched with the size of the liquid outlet of the drip nozzle

The utility model has the advantages that:

the utility model discloses be provided with the extrusion cavity of spring tube shape in the bottom of liquid drop bottle body, the biggest variable volume of extrusion cavity sets up to the volume of a drop of liquid more than one time more than the twice below, preferably 1.2-1.5 times of a drop of liquid volume, when needing to use medicine, invert the liquid drop bottle, the extrusion cavity is pressed to the finger, once presses, extrudes a drop of liquid, can accurately control the extrusion capacity, can not cause the difference of extrusion capacity because of finger extrusion pressure degree difference; the extrusion cavity is in the shape of the spring tube, so that the extrusion cavity is more labor-saving to press and easier to reset, and the extrusion cavity automatically resets after the extrusion cavity is loosened by fingers; the extrusion cavity is arranged at the bottom of the dropping bottle, so that the dropping operation is more convenient.

Drawings

The present invention will be further explained with reference to the accompanying drawings.

FIG. 1 is a schematic view of the structure of the dropping bottle of the present invention;

fig. 2 is a schematic structural diagram in a use state.

In the drawings, the reference numerals denote: 1. a bottle body; 1-1, a groove; 1-2, extruding a cavity; 2. a drip nozzle slide block; 3. a bottle cap; 3-1, sealing the bulge; 4. a bottleneck.

Detailed Description

The present invention will be further described with reference to the following examples.

Referring to fig. 1, the utility model provides a quantitative dropping bottle includes body 1, drip nozzle 2, bottle lid 3 and bottleneck 4, bottleneck 4 with body 1 integrated into one piece sets up, drip nozzle 2 set up in the liquid outlet department of bottleneck 4, drip nozzle 2 can with bottleneck 4 integrated into one piece, also can set up alone in the bottleneck 4, bottle lid 3 with 4 outer wall threaded connection of bottleneck, 3 top inner walls of bottle lid are provided with sealed arch 3-1, and when the dropping bottle was packed up, the bottle lid 3 of screwing, sealed arch 3-1 blockked up in 2 liquid outlets of drip nozzle, prevent that liquid from dripping out. The bottom center position of body 1 is provided with recess 1-1, be provided with extrusion cavity 1-2 on the diapire of recess 1-1, extrusion cavity 1-2 sets up to spring tube shape, with body 1 inner chamber UNICOM, the extrusion cavity of spring tube shape is pressed more laborsavingly, and extrusion volume control is more accurate, and it is easier to reset. The height of the extrusion cavity 1-2 in the non-pressing state is less than or equal to the depth of the groove 1-1 at the bottom of the bottle body 1, and the placement of the dropping bottle is not influenced. The maximum variable volume of the extrusion cavity is more than one time and less than two times of the volume of one drop of liquid, and the optimal maximum variable volume of the extrusion cavity is 1.2-1.5 times of the volume of one drop of liquid, so that one drop of liquid extruded by one pressing can be effectively controlled, and the dropping amount of one pressing can be ensured.

Referring to fig. 2, when in use, the bottle cap 4 is taken down, the bottle body 1 is inverted, the finger presses the extrusion cavity 1-2, liquid is dripped from the drip nozzle 2, and the maximum variable volume of the extrusion cavity is 1.2-1.5 times of that of one drop of liquid, so that one extrusion is carried out, the extrusion of one drop of liquid is ensured, the use is more convenient, and the dosage is accurate.
