- the elongated hollow body 22 may have a tubular shape, for example open on one of its sides so as to form a lateral opening 25. It may thus partially enclose a so-called external portion of the first piston 14.
- the so-called external portion corresponds to the part of the first piston located outside the first compartment 11.
- the first piston 14 is shown here in its fully retracted position.
- the lateral opening 25 of the elongated hollow body 22 can extend above the so-called actuating end 15 of the first piston 14 when the latter is in its fully retracted position, so that it is impossible for the user to actuate this first piston 14 inadvertently.
- the first chamber 23 of this first compartment 11 receives for example the appetizing matrix, thus ensuring no loss of appetizing matrix or that the latter cannot be delivered alone.
- the so-called actuating ends 15, 20 of the first and second pistons 14, 19 have, for example, complementary shapes so that they can be assembled by form engagement to form a common actuating head 26 allowing the simultaneous actuation of these pistons.
- these so-called actuating ends 15, 20 can be shaped to ensure the movement of the common actuating head 26 for the actuation of the pistons 14, 19 through the lateral opening defined by the elongated hollow body 22.
- the outlet orifice 12 of the first compartment 11 may be off-center, or even offset to the side, to bring the outlet orifices 12, 17 of the two compartments 11, 16 closer together.
- the spacing between these outlet orifices 12, 17 is less than or equal to 1.5 cm, preferably less than or equal to 1.0 cm or even more preferably, less than or equal to 0.5 cm.

- the volume of liquid product stored in the second compartment is for example 5 mL or 1 mL.
- the common actuation head 26 of the pistons can make it possible to dose each liquid product at a rate of 0.05 - 0.25 mL/kg for the product contained in the second compartment 16 and 0.1 to 1 mL/kg for the liquid product contained in the first compartment 11.
- the instrument thus makes it possible to dose very precise volumes.

- the instrument 50 shown in Figs. 5 and 6 differs from that illustrated in Figs. 1 to 4, in that the so-called actuating ends 51, 52 of the pistons have complementary shapes to ensure their assembly by engagement, which are of a different configuration. In particular, they are less wide, the lateral opening of the longitudinal hollow body 53 being narrower here.
- the cross section of the housing defined by the lateral extensions 54 and the outer wall of the first compartment is also substantially different in being more rounded and therefore closer to a C than to a U.
- FIGs. 7 to 9 illustrate a base 70, 80 for simultaneously loading the compartments of an instrument for dispensing a first product and a second product, called a double-compartment instrument, according to three variant embodiments.
- Each of these bases 70, 80 may comprise supports for connecting thereto, for example, two containers 71, 72, 81, 82.

- Each of these liquid supply circuits may for example comprise a pipe 83, 84, opening at its other end onto a corresponding orifice 73, 74, 85, 86 of the base 88 for receiving and supporting a dual-compartment instrument.
- the supply circuits and more particularly the pipes 83, 84 form means of connection of the first and second compartments 11, 16, to the containers 71, 72, 81, 82. [0142] These liquid supply circuits 83, 84 are therefore completely separate so that each compartment 11, 16 to be filled with the instrument can only be loaded with a single corresponding liquid product.
- the orifices 73, 74, 85, 86 of this receiving and supporting base 88 are intended to receive and be connected for example by plugging with the ends of the compartments comprising the outlet orifices 12, 17.
- the outlet orifices can be in the form of plugs, or pins.
- the orifices 73, 74, 85, 86 can thus form a sort of socket on which the instrument to be filled is connected.
- the orifices 73, 74, 85, 86 of this receiving and support base 88 may have different diameters, each corresponding to the diameter of the outlet orifice 12, 17 of a respective compartment 11, 16 to provide a foolproofing function.
- the orifices 73, 74, 85, 86 of this receiving and support base 88 can be hermetically sealable using a plug 87, for example screwed.
- This plug 87 can come from one of the containers 71, 72, 81, 82.
- At least one of the containers 71, 72, 81, 82 may be a solution storage bag.
- Figs. 10 to 11 illustrate a base 90 for simultaneously loading the compartments of an instrument for dispensing a first product and a second product, called a dual-compartment instrument, according to a fourth embodiment.
- the base 90 shown in Figs. 10 and 11 differs essentially from those shown in Figs. 7 and 9 in that its receiving and supporting base 91 comprises a support 92 for receiving the instrument 10, 50 for dispensing a first product and at least one second product, between two uses of the latter.
- the conduits 93 of the receiving and supporting base 91 are removable so that they can be replaced at least in part by new conduits, when the instrument is intended to receive at least one new product.
