Thick-bottom glass injection bottle with conical groove and manufacturing method of thick-bottom glass injection bottle

Abstract

The invention discloses a thick-bottom glass injection bottle with a conical groove and a manufacturing method of the thick-bottom glass injection bottle. The glass injection bottle comprises a bottle opening, a bottle body and a bottle bottom. The bottle bottom is of a thickened structure, and an inverted conical groove is formed in the center of the inner wall of the bottle bottom. The upper end of the conical groove is communicated with an inner cavity of the bottle body, and the wall thickness h1 at the lowest point of the conical groove is not smaller than the wall thickness h of the side wall of the bottle body, namely h1 is larger than or equal to h. Through the innovative design of the glass injection bottle bottom structure and the firing forming method thereof, no residue in liquid medicine suction is achieved, the problems that the skin is scratched due to the broken bottle bottom and the injection is scrapped are solved, and the purposes of medication safety and environmental pollution reduction are achieved.

Description

technical field [0001] The invention relates to a glass injection bottle and a manufacturing method thereof, in particular to a glass injection bottle with tapered grooves on the inner wall of the bottom of the bottle and a manufacturing method thereof. Background technique [0002] With the development of the pharmaceutical packaging industry, people pay more and more attention to the issue of drug safety, especially glass-controlled injection bottles because of their thin and fragile walls. requirements are becoming increasingly stringent. [0003] Glass bottles have the advantages of non-toxic, tasteless, transparent, beautiful, good barrier property, and low price, and have become the first choice for packaging of medicines, food and cosmetics. At present, most glass injection bottles use rubber stoppers to seal the bottle mouth, and the bottom of the bottle is an inwardly concave structure at the center. When extracting the medicinal liquid, the medical staff insert th...

AI Technical Summary

Problems solved by technology

At present, most glass injection bottles use rubber stoppers to seal the bottle mouth, and the bottom of the bottle is an inwardly concave structure at the center. When extracting the medicinal liquid, the medical staff insert the needle of the syringe into the bottle, and draw the medicinal liquid in the bottle through the syringe piston. The center point of the inner wall of the bottom of the injection bottle is higher than the peripheral part of the bottom of the bottle. Even if the medical staff tilts the glass bottle, it is difficult to insert the syringe needle into the lowest position of the bottom of the bottle, leaving a small part of the liquid medicine in the bottle. It leads to the waste of liquid medicine, and also brings troubles to the follow-up processing of glass bottles, which easily causes environmental pollution and leakage of toxic and harmful drugs; in addition, because the bottoms of existing glass injection bottles are very thin, the thickness of the bottoms is generally less than Due to the thickness of the bottle body, not only the bottom of the bottle is easy to break, but also it is easy to dump due to the high center of gravity of the bottle. Medical staff must handle it with care when taking it, so as to avoid the bottom of the bottle being broken and scratching the skin and the injection being scrapped.
