Instrument, a system and a container for provisioning a device for personal care treatment, and a device for personal care treatment with such a container

A system for provisioning a device for personal care treatment with a substance to be dispensed from the device, said system comprising:

• an instrument for filling a substance supply container of the device for personal care treatment, the instrument comprising:
• a filling needle having a first end and a second end suitable for connection to a storage reservoir, a substance transport conduit extending from the second end to at least one outlet provided in a radially facing surface portion closely adjacent the first end of the filling needle;
• and
• a sleeve around the filling needle movable between a first position closing off the at least one outlet and a second position away from the first position, wherein the sleeve includes a guiding portion which fits over a wall of a refill socket of the substance supply container to be filled;
• said container bounding a storage area for storing the substance, said container being connectable to a substance dispensing structure of the device, and having the refill socket for connecting the container to the filling needle in a filling position for filling the container, said refill socket comprising:
• a passage extending from an inlet end outside the storage area of a free space communicating with the storage area, said passage having a narrowest section, said free space inside of the narrowest section extending radially from the narrowest section of the passage or from a continuation of the narrowest section of the passage, for receiving a substance flow out of the at least one outlet of the filling needle in the filling position, and
• a valve body displaceable between a closed position and an opened position, the valve body in the closed position closing off the passage, and the valve body in the opened position being inwardly spaced from the narrowest section of the passage and contacting the filling needle in the filling position extending through the passage and holding the valve body in the opened position,
• wherein the sleeve contacts the inlet end of the passage when the filling needle is in a position projecting into the passage.

A container for holding a supply of a substance to be dispensed from a device for personal care treatment, said container bounding a storage area for storing the substance, said container being connectable to a substance dispensing structure of the device for personal care treatment, and having a refill socket for connecting the container to a filling needle of an instrument in a filling position for filling the container, said refill socket comprising:

• a passage extending from an inlet end outside the storage area to a free space communicating with the storage area, said passage having a narrowest section, said free space inside of the narrowest section extending radially from the narrowest section of the passage or from a continuation of the narrowest section of the passage, for receiving a substance flow out of the at least one outlet of the filling needle when the filling needle extends into said free space, and
• a valve body displaceable between a closed position and an opened position, the valve body in the closed position closing off the passage and in the opened position being inwardly spaced from at least the narrowest section of the passage, the valve body being arranged for contacting the filling needle when the filling needle extends into said free space for holding the valve body in the opened position,
• wherein the narrowest section is bounded by the wall of the refill socket, and wherein a material of the wall is softer than a material of the valve body.
