Week 2 Report

I was suggested to develop the idea of the liquid medicine bottle from last week.

It helps you to get the right proportion of liquid each time without using measuring cups or tools. This development makes the process more hygiene, convenient, accurate for those people with poor eye sight, especially the elderly.

This week, I'm more focus on its size, shape, material, function and manufacture stream.

Here are some liquid containers that I collected. The diameter of the cross section is mostly around 50mm. I think this data is more ergonomically concern about the average grip.

250 ml is more often use for the liquid medicine bottle. by calculation, the bottle's height should no less than 130mm. So this was the primary concept it came out.

From the bottle I've been observed. The base side are usually have a downward concavity. It makes the bottle less contact with other surface and reduces the probability of cross contamination. They also caused by the molding process.

I did some sketches about different angles of the liquid flow. I was quite challenged by the air pressure and liquid weight. I didn't notice that, at some point, the liquid won't have enough pressure to get through the tunnel and fill the upper space when you flip it over.

It might require some pressure to squeeze the air in bottle to maintain the accuracy. I chose PET as the main material last time. I found this material is tensitive and might require more pressure to squeeze. While LDPE is easier for the elderly. And they also work well with liquid as eye drop bottle.

The bottle is not refillable as we normally can't fully remove the old chemical products that involved.

I think the aluminum tube can also be concerned. The brand Jurlique using this form for their hand cream for less waste. I would like to use it to maintain the air pressure. While the bottom part still needs to be solid and transparent to check the level of the liquid. It's better than the cylinder as you don't need to squeeze it all the time.  However it might cost more to produce. Using the darker color will protect the liquid from the sun light. I've also considered the Tetrapak with a screwed lid. It might cost less. It's optional printing on the plastic and using less color will be a better option for the environment
