Abstract

The utility model relates to an eye dropping bottle for arranging eye drops, belonging to the field of medicine. A container of the eye dropping bottle comprises a medicinal liquid bottle 1 and a bottle cap 2 which is in screw connection with the medicinal liquid bottle, wherein, an inner plug 3 is fixed on a bottle mouth of the medicinal liquid bottle 1, and a sealed mouth device 4 which is matched with an outer end mouth of the inner plug 3 is fixed on the inner end surface of the bottle cap 2. Because the inner plug 3 is arranged between the medicinal liquid bottle 1 and the bottle cap 2 in the eye dropping bottle, eye drops can be caused to fill in the medicinal liquid bottle 1 conveniently. Because the outer end of the inner plug 3 is smooth, when eye drops are dripped, the outer end of the inner plug 3 can not puncture canthus, eyelids, etc. The medicinal liquid bottle can be sealed tightly after the medicinal liquid bottle is used, and the utility model has the advantage of convenient storage.

Description

A kind of eye drop bottle

This utility model relates to the liquid medicine bottle of a kind of field of medicaments splendid attire eye drop (collyrium).

Along with developing rapidly of plastics industry, in the medical packaging material, adopt nontoxic medicinal plastics such as polyethylene, polypropylene or polystyrene mostly.Eye drop bottle (eyedrops bottle) also changes present normally used plastic bottle into by traditional vial.The eye drop bottle that uses is made up of plastic bottle and vinyl cover two parts at present.This plastic bottle is made the packing container of eye drop, compare with traditional vial, though have advantages such as being convenient to transportation, easy to use, safe and sanitary, this plastic bottle is more tiny because of plastics spout aborning, need the evacuation liquid drug, it is even that its loading amount is difficult to reach.And this plastic bottle is easy cleaning not, has shortcomings such as labor strength is big.Moreover, this plastic bottle in use find because of bottle mouth position be heat sealing, could use after need the heat sealing of bottle mouth position being cut (cutting) mouth with shears, and the edge corner angle of otch are harder, sharp, careless slightly in the use, be easy to stab or scratch canthus, eyelid, bring new injury with painful to the patient.This plastic bottle, because cooperating between bottle and the bottle cap is bad, bottleneck is once cut (cutting) and opened, bottle cap seals difficulty and bottleneck, so first bottle the easy oxidation by air of eye drop in or be subjected to contamination by micro and lost efficacy; Second eye drop will be easy to from leakyring, and carry very difficulty.

The purpose of this utility model is in order to provide a kind of simple in structure, to be convenient to quantitative filling, the convenient eye drop bottle that uses.

This utility model is achieved in that it comprises the liquid medicine bottle bottle that is made of plastics and the bottle cap that is connected with screw thread with bottle.Its technical essential is: bolt in one of the bottleneck top of liquid medicine bottle fixed installation is tapered.Inner face at bottle cap is fixed with a sealer that matches with the outer end of interior bolt, so that after bottle cap is tightened, the external port of interior bolt is sealed up, in case the eye drop in the bottle leaks and the entering of extraneous air and microorganism.As long as open bottle cap during use, extrusion bottle just can ooze eye drop.After using up,, just the interior bolt outer end that is fixed on the bottleneck can be sealed up as long as tighten bottle cap.

Because this utility model is to fix an interior bolt to make on the bottleneck of liquid medicine bottle.When the fill eye drop, as long as take off interior bolt, expose bigger bottleneck, just can easily eye drop be filled in the liquid medicine bottle.Behind the intact eye drop of fill,, just can reach the purpose of sealing eye drop bottle as long as load onto interior bolt and tighten bottle cap.Just can use easily as long as open bottle cap during use,, therefore can not produce the situation of stabbing, scratching canthus, eyelid owing to the slick and sly indent in the outer end of interior bolt, no corner angle, safe and reliable.Tighten bottle cap as long as use up the back, can return to the sealing effectiveness that bottle cap is tightened after to the liquid medicine bottle fill again.So also help the preservation of the eye drop in the eye drop bottle and carry.

Fig. 1: be the structure principle chart in this utility model;

Fig. 2: the A-A section diagrammatic sketch that is Fig. 1;

Below in conjunction with accompanying drawing this utility model is described in detail.

Liquid medicine bottle 1 of the present utility model and bottle cap 2 adopt the plastics manufacturing.Adopt between liquid medicine bottle 1 and the bottle cap 2 and be threaded.Be installed with an interior bolt 3 on the bottleneck of liquid medicine bottle 1, interior bolt 3 is following big, last little hollow-cone body.Interior bolt 3 can adopt with fixedlying connected of liquid medicine bottle 1 and be threaded, and also can adopt clamping.So-called interface arrangment is that the bottleneck at liquid medicine bottle is provided with all annular boss, and is provided with all C shape draw-in grooves in the outside, middle part of interior bolt 3, the C shape draw-in groove in the outside, interior bolt 3 middle parts is contained on the boss of bottle mouth position of liquid medicine bottle to form.Inner face at bottle cap 2 is fixed with a sealer 4 that matches with the outer end of interior bolt 3, and sealer 4 can be to be the round boss of one with bottle cap 2, and this round boss snaps in the outer stomidium of interior bolt 3, to reach sealing function.Sealer 4 also can be a rubber blanket or other sealing gaskets.For the eye drop bottle behind the filling and capping is not arbitrarily opened, on bottle cap 2, be provided with safety, these safety are to be connected with a relieving ring 5 in the lower end of bottle cap 2 through connection strap 6, the inboard of relieving ring 5 is provided with the ratchet 7 of band pawl wheel, and the corresponding part on liquid medicine bottle 1 is provided with ratchet 8.When bottle cap 2 was screwed on the liquid medicine bottle 1, ratchet 7 was a forward rotation like this, and ratchet 7 can not block ratchet 8, and 2 of bottle caps drive relieving ring 5 and rotate, and bottle cap 2 is tightened.If when opening bottle cap 2, ratchet 7 is wanted backward rotation, it is just blocked by ratchet 8, can not rotate with bottle cap 2.Because connection strap 6 is thinner thin connectors, when converse rotating force reached certain value, it will rupture.Connection strap 6 is in case fracture shows that then bottle cap 2 was opened.In order to make ratchet 7 play anti-reverse effect preferably, ratchet 7 is preferably strip.When bottle cap 2 was just changeing like this, ratchet 7 will be attached to the medial surface of relieving ring 5, and after rotateing in place, ratchet 7 snaps in the teeth groove of ratchet 8 under the effect of self elastic force.
