Benefits of technology

[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.

Embodiment Construction

[0038] With reference to FIGS. 1-3, there is shown a squeeze bottle 10 in accordance with the present invention having a neck 14 with an open end 16, see also FIG. 4, which is an enlarged view of the neck 14 of the bottle 10 in accordance with the present invention.

[0039] The bottle 10 may be formed from a suitable material, such as, for example, low-density polyethylene. The bottle 10 has a specific volume of 5 ml for containing a medicament 20 suitable for installation into an eye, not shown, by droplet formation, as will be hereinafter discussed in greater detail.

[0040]FIGS. 5-7 illustrate a bottle 24 in accordance with the present invention similar to that shown in FIGS. 1-3 with the bottle 24 having a specific volume of 10 ml and a neck 26 with an opening 28 therein.

[0041]FIGS. 8-10 illustrate a bottle 32 in accordance with the present invention which has a specific volume of 15 ml along with a neck 34, an opening 36.

[0042] As illustrated in FIGS. 12-14, a tip 40 in accorda...

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, ...
