Description

Plastic ampoule medicament bottle

Technical field

This utility model belongs to a kind of medical packaging container, the plastic ampoule medicament bottle of the low dose of injection of particularly a kind of splendid attire.

Background technology

Plastic ampoule medicament bottle is a kind of through being commonly used to the medical packaging container of the low dose of injection of splendid attire.Its appearance is when occurring in the glass ampule medicine bottle and open, and the glass chip of incision position falls into the problem that injection threatens patient safety.Plastic ampoule medicament bottle generally is to be made of bottle cap, bottleneck and bottle, tearing configuration a little less than all being provided with relative thin between bottle cap and the bottleneck, for the ease of twisting off tearing configuration, near the bottle cap of tearing configuration and bottleneck, be provided with the wing plate of being convenient to grasping separately again.When extracting the medicinal liquid in the plastic ampoule medicament bottle, earlier with the cotton swab that dips in disinfectant with the dust wiped clean at the tearing configuration place between bottle cap and the bottleneck and carry out disinfection, the also reverse rotation of then wing plate on bottle cap and the bottleneck being held with a firm grip makes the fault structure fracture, and the syringe needle of reuse syringe reaches in the bottle by the fracture on the ampoule medicament bottle bottleneck and gets final product.The medicine bottle problem that chip enters injection that comes off itself can not take place in this operating process when ampoule medicament bottle ruptures.But owing near the bottle cap of tearing configuration and bottleneck, be provided with the wing plate of being convenient to grasping separately, and the distance between two parts wing plate of most plastic ampoule medicament bottles can not allow disinfecting cotton swab pass through smoothly, as " the plastic ampoule bottle " of No. 2007200786147, " the novel plastic injection ampoule " of No. 2005200254201, Chinese patent application and Chinese patent application; Even if can allow disinfecting cotton swab pass through smoothly apart from broad between two parts wing plate that has, as No. 2004800097016, Chinese patent application, the tearing configuration owing to them all is arranged in the annular slit, make disinfecting cotton swab will not be in the dust wiped clean at the tearing configuration place in the slit and effectively sterilize reliably, this just might be in residual dust in tearing configuration place and microorganism.Although when tearing configuration is twisted off, do not produce the chip that comes off of ampoule medicament bottle itself like this, but remain in the dust and the microorganism at tearing configuration place in the slit, when tearing configuration is twisted off, but can fall into ampoule medicament bottle and pollute injection, threaten patient safety because of vibrations and scraping.

Summary of the invention

The purpose of this utility model is will provide a kind of can effectively prevent in opening process, and injection is by the plastic ampoule medicament bottle of dust and microbial contamination in the bottle.

In order to achieve the above object, the solution that the utility model proposes is: a kind of plastic ampoule medicament bottle, and it comprises that the last intrasegmental part of bottle cap, bottleneck and bottle, particularly bottleneck is a taper hole, two projections that there is screw thread the outside or distributes relatively; The ring wall of bottle cap has the female thread with bottleneck epimere external screw thread or projection coupling, there is the closeouts with the inner taper hole coupling of bottleneck epimere in bottle cap top board central authorities, when bottle cap is screwing the taper hole sealing on the bottleneck after, the sealing ring that can tear of reuse is enclosed within the outside of bottle cap bottom and bottleneck hypomere, with welding or bonding method by sealing ring with the gap closing between bottle cap and the bottleneck.

After this utility model provides injection fill in the plastic ampoule medicament bottle to finish, earlier bottle cap screwing on bottleneck, the strength of utilizing screw thread rotation is sealed the tight pressing of taper hole of intrasegmental part on the closeouts of bottle cap top board central authorities and the bottleneck with plastic ampoule medicament bottle.The sealing ring that can tear of reuse is enclosed within the outside of bottle cap bottom and bottleneck hypomere, with welding or bonding method by sealing ring with the gap closing between bottle cap and the bottleneck.When opening plastic ampoule medicament bottle provided by the utility model and extracting wherein medicinal liquid, needn't use the cotton swab that dips in disinfectant with the dust wiped clean of the sealing ring between bottle cap and the bottleneck and carry out disinfection, the sealing ring that the bottle cap of only need directly outwarding winding seals slit between bottle cap and the bottleneck simultaneously also is torn, the taper hole that exposes bottleneck inside extend into the syringe needle of syringe in the bottle by taper hole and gets final product.Because the epimere of bottleneck comprises that taper hole is in the clean environment of sealing always, and tear-strap is below the taper hole periphery, even there are dust and microorganism in the outside of bottle cap and sealing ring like this, in the process that bottle cap is opened, also can not cause the pollution of injection in the bottle.

The closeouts of the bottle cap top board central authorities of described plastic ampoule medicament bottle and the inner taper hole coupling of bottleneck epimere can be conical head or sealing ring.

As further improvement of the utility model, also the top, outside of bottle cap ring wall evenly can be provided with the vertical crest line of the projection that is no less than two; Shoulder at bottle is provided with two symmetric stand-up collars, so that the grasping and firmly of bottle cap when opening.

As further improvement of the utility model, also can be with bottle cap top and bottleneck hypomere respectively with butterfly piece parcel up and down, so that the grasping and firmly of bottle cap when opening.
