Portable device, dispensing method, reservoir, and system including such a device and reservoir

A system for the measuring out of at least one ingredient contained in a reservoir, the system comprising:

• a guiding bore mounted on the reservoir;
• an opening having delivery means for delivering the ingredient out of the reservoir, said delivery means including an engaging hub;
• an identifier including identifying information of the ingredient contained by the reservoir;
• a mobile device for measuring out of at least one ingredient contained in a reservoir, said mobile device including:
• a guiding rod having a first axis for slidably engaging into a guiding bore of the reservoir creating a sliding type mechanical connection along said first axis in a reversible and mobile manner, the mechanical connection being configured to prevent rotation of the mobile device with respect to the reservoir, the device being mobile with respect to the reservoir;
• a reader for reading the identifying information on the identifier;
• a motor with a power transmission shaft for interlocking with the engaging hub of the delivery means on the reservoir and for actuating delivery of the ingredient from the reservoir, the guiding rod being separate from the power transmission shaft such that the guiding rod and the guiding bore guide the mobile device up to or from the state where the power transmission shaft is interlocked with the engaging hub, the power transmission shaft having an axis of rotation parallel to the first axis such that the interlocking of the shaft with the engaging hub of the delivery means and the engagement of the guiding rod into the guiding bore are carried out in one translational motion along the first axis;
• a container for receiving the ingredient from the reservoir;
• a means of acquisition of a mass measurement of the ingredient delivered into the container;
• a controller configured to activate the motor to drive the delivery means when the guiding rod is sensed to interlock with the guiding bore and the ingredient is identified by the reader, the controller is configured to maintain the motor activated until the mass of the ingredient acquired by the means of acquisition is equal to the predetermined mass for the ingredient.

A method for measuring out at least one ingredient contained in a reservoir and being associated with a predetermined mass, comprising the following steps:

• slidably engaging a mobile measuring device to the reservoir in a way so as to create a mechanical connection configured to prevent rotation of the mobile measuring device with respect to the reservoir, by sliding a guiding rod of the mobile measuring device in a guiding bore of the reservoir along a first axis in a reversible and mobile manner, the device being mobile with respect to the reservoir;
• interlocking a power transmission shaft of a motor of the measuring device with an engaging hub of a delivery means on the reservoir, the guiding rod being separate from the power transmission shaft such that the guiding rod and the guiding bore guide the mobile device up to or from the state where the power transmission shaft is interlocked with the engaging hub, the power transmission shaft having an axis of rotation parallel to the first axis such that the interlocking of the power transmission shaft with the engaging hub of the delivery means and the engagement of the guiding rod into the guiding bore are carried out in one translational motion along the first axis;
• detecting identifying information of the ingredient by reading an identifier on the reservoir;
• delivering the ingredient from the reservoir to a container in the measuring device by actuating the delivery means with the motor with the power transmission shaft;
• acquiring of a mass measurement of the ingredient delivered into the container,
• wherein said step of delivering is carried out by activating the motor of the device when the ingredient to be measured out is identified and when the guiding rod is sensed to interlock with the guiding bore, until the mass of the ingredient delivered into the container is equal to the predetermined mass for the ingredient.
