SMALL-SIZED DEVICE FOR LIQUID SUPPLY Russian patent published in 2008 - IPC B05B7/24 

FIELD: technological processes.

SUBSTANCE: container is used with accessories for spray application of liquids that are filled by self-flow. Container consists of the following: extended section of casing made of thin elastic polymer material, which has central axis and first and second butt-ends that mutually spaced along axis; facilities for overlapping of second butt-end of casing section; the first adapter that is fixed on the first butt-end of casing section, facilities for overlapping, and also the first adapter that has internal surfaces, which create cavity in container. The first adapter includes engaging section with through opening, which communicates to cavity in container and is adjusted for liquid/airtight engagement with internal channel of device for liquid application by spraying. Container also contains multiple rigid rings that are fixed and mutually spaced along axis along casing section. Container may be filled with liquid in case of manual folding of container casing section between the rings, at installation of one end section of filling pipette in internal surface of engaging section and immersion of opposite end section of filling pipette in liquid, and distancing of the second end section of casing from the first end section of casing for increase of cavity volume, which conditions liquid supply in container cavity under effect of atmospheric pressure through filling pipette. Section of casing is folded between the mentioned rings, providing the possibility of these rings displacement in position of their direct contact with each other for reduction of cavity volume in container as container liquid flows through the opening in the first adapter, while the second butt-end of container is placed on top, thus preventing vacuum pulling in the cavity. Other versions of container are also provided.

EFFECT: inventions are economical and simple in use.
