The aim of this study is to examine the distribution of hand grip force and the movement of the hand
and fingers during squeezing a bottle for older groups. In this experiment, the author used the different liquids;
mayonnaise, tomato sauce, shampoo and skin cream. The maximum hand force, hand grip style and location,
human perception and hand pain experience will be collected through the Tekscan Software result and
interviews the responses after undertaken this activity. The results from this study found that the age and human
capability is one of the factors why the distribution area on force at the hand and finger for all participants
shows a significant difference. The hand and finger movement is related with the higher grip force. The type of
the liquid and the design of bottle which is include bottle material, shape and nozzle matching shows a different
force when do the comparison data. The hand and finger movement for all participants was seen to be different
depending on the age, hand grip style, human capability and the movement of the finger. The result found the
age is one of the likely factors why the distribution areas on force at the hand and fingers for all participants
show a significant. The motion of the hand and finger for the female (smaller hand size) are more frequent than
the male (bigger hand size). The continuous maximum force action in difficult areas and bottle material and
design cause pain and discomfort on the hand. Therefore, it is primarily to redesign a more flexible and elastic
bottle in order to reduce the pain suffered. The hand and finger movement is related with the higher grip force.
The female shows a lower force when compared with the male. The hand and finger movement for all
participants was seen to be different depending on the grip style and the movement of the finger
This paper outlines these results and proposes further work with the ultimate aim of providing suitable insight
for the redesign of packaging product to reduce instances of discomfort and illness.
