TECHNICAL FIELD
-
The invention relates to means for storing, stirring and mixing liquid compositions, and in particular to containers for storing, stirring and mixing paint.
BACKGROUND ART
-
Various types of liquids with high viscosity are stored, sold and stirred/mixed in containers. Such viscous liquids as paint are multi component compositions which tend to layer-out the components such as oil part and paint part and must me stirred prior to use for the paint composition to be well mixed again. Usually, the paint is sold in disposable containers with a re-closable top lid and bottom wall permanently sealed to side wall. The containers are usually made of plastic material or tin material and so that would minimise the cost of sold paint. The bottom wall and the lid are usually flexible - the thickness of container side wall, bottom and lid are just enough thought so that the container would not break easily and keep the paint airtight.
-
Prior to use of the paint the container is opened and subjected to stirring by stirring means which are immersed into the container thus stirring the base paint and if added some colour pigments. The paint can also be stirred and mixed using paint mixing machines where the paint container is clamped between two holding plates and afterwards subjected to gyroscopic or alike motion. In general, the stirring means are either stationary and bulky devices or low safety and messy handheld mixers. The stationary paint mixers are found only at paint sales stores because they are too expensive to purchase for one time paint jobs. And handheld mixers such as power drill with an attached mixing bit are messy and must be used with a certain amount of skill to stir the paint properly. Moreover the handheld device requires the entire lid or at least part of it to be opened burdening the user with splashing the paint wile mixing or inadvertently spilling the paint by toppling the container while mixing.

Such inner ring-shaped agitator body (5.11‴ʺ) can be rotated using an outer ring-shaped agitator body (5.12‴ʺ) disposed in a frame (7) for surrounding the container (CNT) when the container (CNT) is inserted into the outer ring-shaped agitator body (5.12‴ʺ) and the outer ring-shaped agitator body (5.12‴ʺ) would be aligned with the inner ring-shaped agitator body (5.11‴ʺ) so that when the outer ring-shaped agitator body (5.12‴ʺ) is rotated by external rotation means (6) via a gear or belt system it would rotate the inner ring-shaped agitator body (5.11‴ʺ) via magnetic interaction. The outer ring-shaped agitator body (5.12‴ʺ) comprises permanent magnets or ferromagnetic material, or both. The outer ring-shaped agitator body (5.12ʺʺ) may comprise bearing elements for reducing friction.
