A kind of medicinal packing bottle

Technical field

The utility model relates to medical package bottle technical fields, and in particular to a kind of for storing the bottle type container of drug.

Background technique

Medicinal packing bottle is the main packing container of the drugs such as medicinal reagent, pulvis, is mostly made of glass.Medicinal glass bottle Have the characteristics that clear transparent, easily disinfection, resistant to corrosion, high temperature resistant, good seal performance.

Currently, medicinal packing bottle especially vial is only using the threaded connection between bottle body and bottle cap as main sealing Measure can not easily cause in medicine bottle when Packaging Bottle is vibrated or bottle cap closure is not tight in forming sealed environment in Packaging Bottle Portion's reagent is polluted by ambient atmos or medicament volatilizees, and then causes medicament drug effect to reduce and even lose effectiveness.

Utility model content

The utility model provides a kind of pharmaceutical pack precisely in order to avoid above-mentioned existing deficiencies in the technology Bottle.

The present invention adopts the following technical scheme that a kind of medicinal packing bottle in order to solve the technical problem, the bottle including mating connection Body and bottle cap, the bottle body and the closure inside form the cavity for holding drug, and the bottle cap bottom sets cavity, piston seal It is matched in the cavity, push rod passes through the bottle cap, and bottom end is connect with the piston, and the piston can be driven in described It is slided up and down in cavity；End plate is set at the top of the push rod, spring is set to outside the push rod, and the bottle cap is pressed at both ends respectively Upper surface and the end plate lower surface, and tend to push up the push rod.

Further, the groove that the bottleneck of the bottle cap bottom setting and the bottle body cooperates, and set in the groove Gasket seal, the bottle body and the bottle cap set helicitic texture respectively at the bottleneck and the groove, and pass through screw thread knot Structure is cooperatively connected.

Further, the medial surface of the bottle lid groove sets o-ring groove, and sealing ring, institute are set in the o-ring groove The bottleneck inner sidewall that sealing ring is pressed in the bottle body is stated, for realizing the sealing of the bottle body and bottle cap.

Further, the Bottle cap top is connected with measuring cup, and the measuring cup side wall is equipped with scale, for measuring medical fluid.

Further, the bottle body bottom is equipped with sunk structure.

The utility model provides a kind of medicinal packing bottle, has the advantages that

1, it is equipped with triple seal structure, the tight fit on the inside of sealing ring and bottleneck ensures that volatility medical fluid remains in container Inside, avoids medical fluid volatilization loss, and the cooperation of gasket seal and bottleneck completely cuts off outside air in bottle mouth position and internal medical fluid, prevents Only outside air, which penetrates into Packaging Bottle, causes liquid medicine contamination rotten, and bottle cap inner ring piston, push rod and spring structure realize gas in bottle The reduction of pressure, and the leakproofness of Packaging Bottle is further enhanced using draught head, it ensure that the stability and purity of medical fluid；

2, structure is simple, favorable sealing property, and the stability and purity of medical fluid is effectively ensured, practical.

3, Bottle cap top is connected with measuring cup, uses convenient for the measurement of medical fluid, avoids medical fluid and generate waste in measurement.

Detailed description of the invention

Specific embodiment

It is practical new below in conjunction with this to keep the objectives, technical solutions, and advantages of the embodiments of the present invention clearer Type embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that described implementation Example is the utility model a part of the embodiment, instead of all the embodiments.Based on the embodiments of the present invention, this field Those of ordinary skill's every other embodiment obtained without creative efforts, belongs to the utility model The range of protection.

As shown in FIG. 1 to FIG. 2, structural relation are as follows: in bottle body 1 and bottle cap 2 including mating connection, bottle body 1 and bottle cap 2 Portion forms the cavity for holding drug, and 2 bottom of bottle cap sets cavity, and the sealing of piston 6 is matched in cavity, and push rod 4 passes through bottle cap 2, Bottom end is connect with piston 6, and piston 6 can be driven in sliding up and down in cavity；End plate is set at the top of push rod 4, spring 5 is set to push rod 4 2 upper surface of bottle cap and end plate lower surface are pressed in outside, both ends respectively, and tend to push up push rod 4.

Preferably, the groove that the setting of 2 bottom of bottle cap cooperates with the bottleneck of bottle body 1, and in setting gasket seal 7, bottle in groove Body 1 and bottle cap 2 set helicitic texture respectively at bottleneck and groove, and pass through helicitic texture and be cooperatively connected.

Preferably, the medial surface of 2 groove of bottle cap sets o-ring groove, and sealing ring 8 is set in o-ring groove, and sealing ring 8 is pressed Tightly in the bottleneck inner sidewall of bottle body 1, for realizing the sealing of bottle body 1 and bottle cap 2.

Preferably, measuring cup 3 is connected at the top of bottle cap 2,3 side wall of measuring cup is equipped with scale, for measuring medical fluid.

Preferably, 1 bottom of bottle body is equipped with sunk structure.

When specifically used, when closed closure 2, overcome the elastic force of spring 5 to press down on push rod 4 and bottle cap 2 is directed at bottle body 1 Bottleneck press, be pressed into contact with sealing ring 8 with bottleneck wall of cup, realize first layer sealing.Bottle cap 2 is rotated, the spiral shell in groove is made The helicitic texture of line structure and bottleneck is cooperatively connected, until bottleneck compression seal gasket 7, realizes second layer sealing.Bottle body 1 is in bottle Lid 2 loosens push rod 4 after the installation is completed, and push rod 4 resets under the action of 5 elastic force of spring, increases the volume of cavity, reduces appearance Intracavitary air pressure makes atmospheric pressure compress bottle cap 2 downwards, realizes third layer sealing, further increases the sealing performance of Packaging Bottle.

When opening bottle cap, after overcoming the elastic force of spring 5 to press down on the releasing third layer sealing of push rod 4, bottle cap 2 is rotated backward Second layer sealing is released, then bottle cap 2 is separated with bottle body 1, releases first layer sealing.

1 bottom of bottle body sets sunk structure, problem of stress concentration caused by can eliminating traditional glass bottle and being influenced by structure, thus The intensity that vial can be improved, vial caused by avoiding transportational process stress from concentrating are damaged.
