Fixed angle is a design of a portable water container designed for the elderly or for anyone who has weak hand joints to lift heavy objects. Most people would pour water from a portable water container at an angle and as the water in the container gets reduced, the angle of the hand goes up giving pressure to the wrist, elbow or even the shoulder joints. For ordinary people, we do this without any problem at all.  However, this simple action can be very difficult for the elderly or for people suffering from weak joints. This problem can be resolved or mitigated by using a fixed angle design in water containers. In the case of fixed angle, water comes out of it at the same angle regardless of the quantity of water. In other words, no additional bending of the wrist or the elbow is needed while pouring water. The water is being pushed upward by the spring that is hidden at the bottom of the container. The spring is made of silicone material which is safe. This design is very beneficial for people that are suffering from weak joints. Moreover, one can comfortably pour water without feeling any pain. In addition, it is also very convenient to wash. Just take out the light and soft silicone material and wash the water container just like any other containers.
