Detailed Description

The present invention is further described with reference to the following drawings and specific embodiments so that those skilled in the art can better understand the present invention and can implement the present invention, but the embodiments are not to be construed as limiting the present invention.

Referring to fig. 1 and 2, an embodiment of an eye drop bottle according to the present invention includes a bottle body 1 and an inner plug 3 inserted into an open end of the bottle body 1, the inner plug 3 includes a liquid outlet channel 31, a buffer channel 32 and a stopper 33, the liquid outlet channel plug is disposed to penetrate along an axial direction of the inner plug 3 to drip an eye drop contained in the bottle body 1, the buffer channel 32 is disposed around a lower end of the liquid outlet channel 31, and the stopper is connected to an upper surface of the buffer channel 32 to seal an upper port 321 of the buffer channel 32, during a use process, the lower ends of the buffer channel 32 and the liquid outlet channel 31 are inserted into the bottle body 1, a lower surface of the stopper 33 abuts against an open end of the bottle body 1 to limit a length of the inner plug 3 inserted into the bottle body 1, and at the same time, in order to increase a fastening property of the inner plug 3 to the bottle body 1, the buffer channel 32 is fitted to the opening of the bottle body 1, since the inner plug 3 is usually made of L, PET, PVC, etc., the inner plug 3 is usually made of a material having a certain elastic deformation, and the opening of the inner plug 3 is not easily fitted to the bottle body 1, and the inner plug 3 does not easily.

Referring to fig. 1 and 2, one end of the liquid outlet channel 31 capable of being inserted into the bottle body 1 is an inlet end 311, and one end located outside the bottle body 1 is an outlet end 312. The buffer passage 32 has an upper port 321 at one end sealed with the baffle, and a lower port 322 at the free end of the buffer passage 32 located inside the bottle body 1. The inlet end 311 of the liquid outlet channel 31 is located inside the buffer channel 32, and the inlet end 311 of the liquid outlet channel 31 is close to the lower port 322 of the buffer channel 32, in this embodiment, the inlet end 311 of the liquid outlet channel 31 is 0.5mm-2mm away from the lower port 322 of the buffer channel 32. The length of the liquid outlet channel 31 is increased, so that the inlet end 311 of the liquid outlet channel 31 is close to the lower port 322 of the buffer channel 32, and the buffer capacity can be greatly improved, thereby reducing the liquid leakage phenomenon.

Referring to fig. 2, the diameter of the opening of the inlet end 311 of the liquid outlet channel 31 is 0.3mm-0.5mm, so that the inlet end 311 of the liquid outlet channel 31 can prevent the large-volume bubbles or break the large-volume bubbles, thereby reducing the bubbles entering the liquid outlet channel 31 and alleviating the phenomena of leakage and unstable dropping amount.

Referring to fig. 2, the outlet end 312 of the outlet channel 31 is a curved surface, and the curved surface has a certain taper, that is, the curved surface can be continuously transited to the end surface of the outlet channel 31 by an arc shape, so as to facilitate dropping of the eye drops, and simultaneously, the influence of dropping of the eye drops caused by the inclination and movement of the bottle body 1 can be reduced.

Referring to fig. 1, a partition 2 is provided inside a bottle body 1, an upper surface and a side surface of the partition 2 are both attached to an inner wall of the bottle body 1, and a certain gap is left between a lower surface of the partition 2 and a bottom wall of the bottle body 1. The partition 2 divides the inside of the bottle body 1 into a first liquid storage chamber 11 and a second liquid storage chamber 12, and because a gap is left between the lower surface of the partition 2 and the bottom wall of the bottle body 1, the first liquid storage chamber 11 and the second liquid storage chamber 12 are communicated with each other. First stock solution chamber 11 and play liquid channel 31 intercommunication, the area of second stock solution chamber 12 is greater than the area of first stock solution chamber 11 simultaneously in this embodiment, therefore most eyedrops can hold inside second stock solution chamber 12. When dropping eyedrops, the eyedrops in the second liquid storage cavity 12 are gathered into the first liquid storage cavity 11 through the gap between the partition part 2 and the bottle body 1, so that the dropping amount at each time can be controlled.

Referring to fig. 1, partition portion 2 is the arc setting, and the convex surface of arc portion sets up towards first stock solution chamber 11 in this embodiment to the volume of increase second stock solution chamber 12 that can be further, so that the amount of drippage in more accurate control first stock solution chamber 11.

Referring to fig. 2, the upper surface of the blocking plate 33 is provided with a plurality of liquid discharge grooves along the circumferential direction, and when the bottle body 1 is erected after dropping the eye drops, a part of the residual eye drops slide onto the blocking plate 33 along the outer wall of the liquid discharge passage 31. The liquid discharge grooves formed in the upper surface of the baffle 33 can quickly discharge the eyedrops sliding onto the baffle 33, so that the eyedrops in the bottle are prevented from being polluted.

Referring to fig. 1, the bottle body 1 is provided at the sidewall thereof with pressing portions integrally formed with the bottle body 1 to facilitate the application of pressure to the bottle body 1. Meanwhile, scales 13 are arranged on the outer side wall of the bottle body 1, so that the dripping amount of each time and the residual amount of eye drop in the bottle can be conveniently checked.
