Description

Eye drop bottle

Technical Field

The utility model relates to a container technical field for the medicine, in particular to eye drop bottle.

Background

The eye drops are aseptic liquid preparations which are prepared from raw material medicaments and proper auxiliary materials and are dripped into eyes, are used in clinic more, have higher requirements on the quality and the safety of the eye drops compared with common preparations due to the particularity of the medicament application parts of the eye drops, and need to achieve the aseptic effect.

Most of the current eye drops exist in the form of multiple doses in an eye drop bottle, and enter the eye through an outlet of an eye drop bottle stopper. The common eye drop bottle in the market has simple design and can not effectively control the flow and the flow velocity of the liquid medicine. When the force is not applied properly, the liquid medicine is easy to drip out continuously or even to be ejected linearly, which not only can not control the clinical usage amount, but also can cause waste for expensive medicines, and even when the eyes have wounds, the liquid medicine is easy to cause secondary wound.

Chinese patent ZL201721588474.8 discloses an eye drop bottle stopper, which comprises a bottle stopper inner tube and a bottle stopper inner buffer space; the upper end opening of the inner tube of the bottle plug is a liquid outlet of the bottle plug, the lower end opening of the inner tube of the bottle plug is a liquid inlet of the bottle plug, the other buffer space inside the bottle plug is arranged at the liquid inlet of the bottle plug, and the cross section of the buffer space inside the bottle plug is in a trapezoidal groove structure.

Chinese patent CN201510666319.2 discloses a novel eye drop bottle, which comprises a bottle cap, a dropping nozzle and a bottle body, wherein the bottle body is made of soft material, and a groove which is beneficial to the extrusion deformation of the bottle body is arranged on the bottle body. The non-extrusion region and two extrusion regions around and are cut apart into with the body to the recess, and during the use, the extrusion region of gently pressing the body of finger can drip out liquid medicine, uses convenient and comfortable swift more.

In summary, the current eye drop bottles in the market still have defects in controlling the dropping speed of the liquid medicine, the eye drop bottles cannot effectively control the dropping speed of the liquid medicine, the liquid medicine is easy to continuously drop out when the eye drop bottles are applied with improper force, and the waste of the liquid medicine is easy to cause when the eye drop bottles cannot control the clinical use amount.

Example 4

The eye drop bottles of examples 1 and 2 were filled with water to a height (not the total height) of the bottle body, and then mounted on a predetermined position of the squeeze tester, and the upper portion, the middle portion, and the lower portion of the center portion of the concave groove of the eye drop bottle were brought into contact with the top of the squeeze tester, and the squeeze tester was started to record the pressing force required for dropping one drop of water from the eye drop bottle, and the average values of the results were shown in table 1 in parallel five times.

TABLE 1 pressing force required for dropping one drop of water

As shown in table 1, it can be seen that the bottle bodies of examples 1 and 2 can conveniently extrude the liquid medicine in the bottle because the groove on the upper portion of the eye drop bottle has a large force bearing area and a large depression, and the pressing force required for dropping one drop of water is small, and the pressing force required for dropping the next drop of water is large because the force bearing area on the lower portion of the bottle is small and the depression is small, so that the liquid medicine is not easily excessively extruded due to excessive force.
