Eye drop bottle design pay attention to these points

Eye drop bottles are an important packaging form of ophthalmic drugs, and the design of the packaging is related to the convenience of patients' later use and the safety of drug storage. In order to ensure the functionality and applicability of the packaging, the following points need to be paid attention to when designing this packaging:

1. Bottle mouth and bottle bottom design: The design of the eye drops bottle mouth should focus on how to make the bottle mouth better fit the bottle cap tightly. The bottom of the bottle is the weak part of the mechanical properties of the plastic bottle, so the bottom of the bottle is generally designed to be concave. The corners and inner recesses of the plastic bottle are all made with larger arcs. In order to facilitate the stacking of plastic bottles and increase the stacking stability of plastic bottles, the bottom of the plastic bottles should be designed with internal grooves. To

2. Bottle body design: When the surface of the plastic bottle needs to be labeled, the surface of the label should be flat. A "frame" can be designed on the surface of the plastic bottle, so that the label can be positioned accurately without movement. In blow molding, the first part of the parison that is blown into contact always tends to harden first. Therefore, the wall thickness of this part is also larger.

3. Improve rigidity: Since most plastics have notch sensitivity, plastic bottles are prone to cracks and cracks at sharp corners, the root of the mouth thread, and the neck. Therefore, these parts should be designed with rounded corners. For the transfer place of the rectangular plastic bottle, it is necessary to support most of the load of the plastic bottle, so locally increasing the wall thickness at this place is also beneficial to improve the rigidity and load resistance of the plastic bottle.

The above are the basic elements that need to be considered when designing the eye drop bottle. In addition, the eye drop is administered by squeezing the bottle body. When selecting the material, try to choose the material with good flexibility to facilitate the extrusion of the drug.
