Description

Injection medicine bottle with inner container

Technical Field

The utility model relates to an injection medicine bottle, in particular to an injection medicine bottle with an inner container.

Background

At present, the full-mouth capacity of an injection glass bottle in the medical packaging material industry is mostly more than 4ml, and the glass bottle is suitable for filling common medicines due to large capacity. With the advent of more and more precious drugs, higher requirements are put forward on drug packaging, and particularly, because the dosage of precious injection drugs is generally very small, the problem of excessive drug residues is easily caused by adopting the existing drug bottle packaging, so that the treatment effect of a patient is influenced, economic loss is brought to the patient, and the waste of medical resources is caused at the same time.

In order to solve the problems, people assume that a nonstandard medicine bottle with the volume less than 4ml is used for packaging precious medicines, but the medicine bottle cannot be matched with the existing tooling equipment in the links of manufacturing, filling, packaging, transportation and the like, and a large amount of manpower and material resources are required to be invested for transforming and debugging the tooling equipment when the specifications of products are switched, so that the production cost of an enterprise is increased, the medicine price is increased, and the burden of a patient is increased.

SUMMERY OF THE UTILITY MODEL

The utility model provides an injection medicine bottle with inner bag aims at the mode through the inside suit inner bag at ordinary injection bottle, realizes splendid attire medicine in the inner bag to make its appearance size and current filling, encapsulation, packing transportation equipment phase-match, reach the purpose that reduces the medicine and remain extravagant, reduce medical cost.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

an injection medicine bottle with an inner container comprises a shell and the inner container, wherein the shell is a cylindrical bottle body, and the external dimension of the shell is consistent with that of an injection medicine bottle with a national standard specified model; the inner container is sleeved in the inner cavity of the shell, the capacity of the inner container is less than 4ml, and the inner container and the shell are converged together at the bottleneck of the bottle mouth.

In the injection medicine bottle with the inner container, the inner container is in a hollow cone structure with an open upper end, and the tip of the cone points to the bottom of the shell.

The diameter of the cylinder of the shell is phi 1=26 mm, the outer diameter of the bottle mouth is phi 2=19.6mm, the inner diameter of the bottle mouth is phi 3= 12.6mm, the total height h1=42mm of the medicine bottle and the total height h2=18.5mm of the inner container.

The injection medicine bottle with the inner container is formed by adopting a borosilicate glass tube as a raw material through a tube-bottle making process.

The utility model provides an injection medicine bottle with inner bag is particularly useful for the packing of little dose injection medicament, because its inner bag capacity is less, the area of contact of medicine with the inner bag wall has been reduced, thereby the too much problem of remaining of medicine has been avoided, in addition because this injection medicine bottle overall dimension is unanimous with the injection medicine bottle of national standard regulation model, can with current preparation, filling, encapsulation, packing transportation equipment phase-match, thereby to the transformation debugging link of construction equipment when having reduced different product specification switches. The preferred embodiment of injection medicine bottle with inner bag is the cone cavity structure for invering the inner bag design, and the medicine is deposit at the most advanced position of cone under self action of gravity, has further reduced the area of contact of medicine with the inner bag wall, more is favorable to solving the extravagant problem of precious medicine. Therefore, the utility model discloses reach the purpose that reduces remaining waste, reduction medical cost of medicine.
