Container system

Abstract

A container system includes a squeeze bottle of a specific volume having a neck with an open end and a medicament disposed within the bottle. A tip is provided which is insertable into the open end of the squeezable bottle and includes an internal tapered nozzle with the nozzle having increased diameter toward a tip opening. A cap is provided for removable attachment to the bottleneck for sealing the tip opening and a shoulder formed in the bottle proximate the neck and disposed at an angle is provided in order to enhance bubbless flow of the medicament to the nozzle and facilitate tamper proof sealing of the cap.

Description

[0001] The present invention generally relates to dropper bottles for dispensing of medicaments in droplet form and is more particularly directed to a container system for dispensing medicaments in less than 100 ml volumes with precise and uniform droplets. [0002] Heretofore, dropwise container systems have typically included nozzles that are press fitted or otherwise inserted into a neck portion of a squeeze bottle. [0003] In operation, squeeze bottle is inverted and manually squeezed by a user to dispense one or more drops through the nozzle. When medicament delivery when the medicament is fully dispensed, the container system is typically discarded. [0004] Heretofore, resilient squeeze bottles often have substantial drop-to-drop volume variation when dispensing one or more drops in volumes of less than 100 ml, particularly in the 10 to 50 ml range. [0005] This variation may be due to a bubble formation on interior surfaces of the bottle when the bottle is inverted so that drops, ...

AI Technical Summary

Benefits of technology

[0010] A cap is provided for removably sealing the tip opening by attachment to the bottleneck.

[0011] A shoulder formed into the bottle proximate the neck and disposed at an angle of between about 45° and about 50° to a bottle centerline, is provided in order to both enhance bubbless flow of medicament to the nozzle and facilitate tamper proof sealing of the cap.

Problems solved by technology

This variation may be due to a bubble formation on interior surfaces of the bottle when the bottle is inverted so that drops, particularly eye drop medication, are dispensed unevenly.
