As shown in fig. 1, the metered-dose eyedrop bottle according to the embodiment of the first aspect of the present invention includes a bottle body 100 and a bottle cap 200, the bottle body 100 is a soft and transparent material member, and may be made of low-density PVC or low-density PET, so as to further reduce the hardness of the bottle body 100, facilitating the pressing of the user. The bottle body 100 is provided with a narrow medicine outlet channel 110, the medicine outlet channel 110 is provided with a medicine outlet 111, the bottle body 100 is provided with outer threads at the position of the medicine outlet channel 110, and the bottle cap 200 is provided with inner threads in matched connection with the outer threads, so that the bottle cap 200 can be detachably connected to the bottle body 100. When the bottle cap 200 is connected to the bottle body 100, the medicine outlet 111 is sealed by the bottle cap 200, so that the eye drops in the bottle body 100 are prevented from leaking outwards.
As shown in fig. 2, a limiting portion 120 is disposed in the bottle body 100, a diversion hole 121 is disposed in the limiting portion 120, the inner cavity of the bottle body 100 is divided into a first liquid storage cavity 101 and a second liquid storage cavity 102 by the limiting portion 120, the volume of the first liquid storage cavity 101 is larger than the volume of the second liquid storage cavity 102, the first liquid storage cavity 101 is communicated with the second liquid storage cavity 102 through the diversion hole 121, and the second liquid storage cavity 102 is directly communicated with the medicine outlet 111. It should be noted that the volume of the second reservoir 102 should be set according to the dosage of the eyedrops used each time, for example, if the dosage of one eyedrop used each time is two drops per eye, the total dosage is about 0.2 ml/two eyes in conversion, and the volume of the second reservoir 102 should be set to be slightly larger than 0.2 ml; the volume of the first reservoir 101 is set according to the design specification of the eyedrop bottle, if the design specification of the eyedrop bottle is 10ml, the volume of the first reservoir 101 is more than 10ml, if the design specification of the eyedrop bottle is 20ml, the volume of the first reservoir 101 is more than 20ml, and so on.
In order to make the eyedrop in the first stock solution chamber 101 smoothly water conservancy diversion to the second stock solution chamber 102 in to prevent the eyedrop refluence in the second stock solution chamber 102 to first stock solution chamber 101 in, the dosing eyedrop bottle still includes one-way water conservancy diversion mechanism 300, one-way water conservancy diversion mechanism 300 includes cock stem 310 and spring 320, cock stem 310 is spacing to be connected in water conservancy diversion hole 121, the spring 320 cover is established outside the cock stem 310, one-way water conservancy diversion mechanism 300 is used for following second stock solution chamber 102 toward first stock solution chamber 101 one-way sealing water conservancy diversion hole 121. Specifically, the plug 310 includes a sealing portion 311, a rod portion 312 and a clamping portion 313, the rod portion 312 passes through the guide hole 121, the size of the rod portion 312 is smaller than that of the guide hole 121, a gap between the rod portion 312 and the guide hole 121 is a guide gap, and both liquid and gas flow through the guide gap. Sealing portion 311 is located in second stock solution chamber 102, sealing portion 311's size of a dimension is greater than the size of a dimension of water conservancy diversion hole 121, sealing portion 311 can cover water conservancy diversion hole 121, joint portion 313 is located in first stock solution chamber 101, joint portion 313's size of a dimension is greater than the external diameter of spring 320, spring 320 cover is established outside pole portion 312, spring 320 is compression spring 320, the one end of spring 320 with spacing portion 120 butt, the other one end of spring 320 with joint portion 313 butt is under the effect of not receiving the external force sealing portion 311 with spacing portion 120 butt is in order to keep right the closure of water conservancy diversion hole 121.
As shown in fig. 3, it should be noted that, on the premise that the bottle cap 200 is connected to the bottle body 100, once the user presses the position of the bottle body 100 where the first liquid storage cavity 101 is located (hereinafter referred to as a lower bottle body), the volume of the first liquid storage cavity 101 is reduced, so that the eyedrops in the first liquid storage cavity 101 generate hydrodynamic force, and if the hydrodynamic force is enough to overcome the elastic force of the spring 320, the hydrodynamic force can push the sealing part 311 open, so that the diversion hole 121 is temporarily opened, and at this time, the eyedrops in the first liquid storage cavity 101 can be diverted to the second liquid storage cavity 102; however, since the bottle cap 200 closes the medicine outlet 111, the gas in the second liquid storage cavity 102 cannot be discharged to the outside of the bottle, so that the gas pressure in the second liquid storage cavity 102 is increased, and when the user stops pressing, since the gas pressure in the second liquid storage cavity 102 is higher than the gas pressure in the first liquid storage cavity 101, the gas in the second liquid storage cavity 102 can escape into the first liquid storage cavity 101 in time, so as to achieve the balance of the gas pressures of the two; because only part of the eyedrops can be guided into the second liquid storage cavity 102 by pressing the lower bottle body each time, the user can gradually fill the second liquid storage cavity 102 with the eyedrops by pressing the lower bottle body for multiple times. In order to reduce the pressing frequency of the lower bottle body, a user can invert the eyedrop bottle firstly, the bottle cap 200 faces downwards at the moment, and then the lower bottle body is pressed for multiple times, at the moment, eyedrop in the first liquid storage cavity 101 is always pressed on the upper surface of the limiting part 120 under the action of gravity, and gas in the second liquid storage cavity 102 is always in contact with the lower surface of the limiting part 120, so that the flowing distance between gas and liquid is reduced.
After the second liquid storage cavity 102 stores the eye drop by the above method, when a user uses the eye drop, the bottle cap 200 needs to be unscrewed first, and then the position of the bottle body 100 where the second liquid storage cavity 102 is located (hereinafter referred to as an upper bottle body) is pressed, so that the eye drop in the second liquid storage cavity 102 generates hydrodynamic force, the hydrodynamic force can further enhance the sealing performance of the plug 310, and the eye drop stored in the second liquid storage cavity 102 can flow out from the drug outlet 111 in the process of pressing the upper bottle body, so that the fixed dosage of the eye drop can be used.
As shown in fig. 2 and 3, in some embodiments of the present invention, in order to further improve the sealing performance of the bottle cap 200, a sealing membrane 210 is disposed on the inner top surface of the bottle cap 200, the sealing membrane 210 may be a rubber member, and after the bottle cap 200 is screwed to the bottle body 100, the sealing membrane 210 abuts against the medicine outlet 111 to prevent the eye drops from leaking out of the medicine outlet 111 when the user presses down the bottle body.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
