    Abstract

    A pouch to hold a fluid. The pouch includes at least two compartments and at least two outlets that are each connected to a tube in each of the compartments. One compartment has a geometry that optimizes the volume of the pouch in order to prevent the pouch from collapsing at an acceptable maximum pressure.

    Description

    BRIEF DESCRIPTION OF THE DRAWINGS

    [0019] The invention shall be better understood using the description, provided hereinafter solely for the purposes of explanation, of an embodiment of the invention, in reference to the Figures wherein:

    [0020] FIGS. 1 and 2 show a pouch according to prior art; and

    [0021] FIGS. 3 and 4 show a pouch according to this invention.

    DETAILED DESCRIPTION OF THE EMBODIMENTS OF THE INVENTION

    [0022] This invention relates to a pouch 10 able to hold a fluid comprising at least two compartments 11, 12 and at least two outlets 13, 14 that are each connected to a tube 15, 16 in each of said compartments 11, 12, wherein one compartment 11 has a geometry that optimizes the volume of said pouch 10 in order to prevent the pouch from collapsing at an acceptable maximum pressure.

    [0023] FIGS. 3 and 4 show a pouch 10 according to this invention.

    [0024] In the FIGS. 3 and 4, a pouch 10 according to this invention can be seen. This pouch comprises two compartments 11 and 12 and two outlets 13 and 14 that are each connected to a tube 15, 16. It can be seen in FIG. 4 that this invention makes it possible to prevent collapsing, thanks to an optimisation of the volume and of the pressures inside the pouch 10.

    [0025] In an embodiment, the edge of said compartment 11 opposite the outlet 13 of the tube 15 has the shape of an arc of a circle.

    [0026] In an embodiment, the edge of said compartment 11 opposite the outlet 13 of the tube 15 has a shape comprised of a plurality of arcs of a circle.

    [0027] In another embodiment, the edge of said compartment 11 opposite the outlet 13 of the tube 15 is comprised of a succession of curves and straight lines.

    [0028] The pouch 10 according to this invention makes it possible to optimise the volume thanks to the pressure exerted on the side walls of the compartment 11.

    [0029] Thanks to this invention, the total pressure on the pouch 10 is homogenised.

    [0030] In an embodiment, the two compartments 11, 12 are separated by a weld, and said weld is peelable.

    [0031] In an embodiment, the volume of the compartment 11 is between 4 ml and 30 ml.

    [0032] More preferably, the volume of the compartment 12 is greater than the volume of the compartment 11.

    [0033] In an embodiment, the volume of the compartment 11 is 7 ml and the volume of the compartment 12 is 93 ml.

    [0034] In another embodiment, the volume of the compartment 11 is 20 ml and the volume of the compartment 12 is 500 ml.

    [0035] In another embodiment, the volume of the compartment 11 is 10 ml and the volume of the compartment 12 is 100 ml.

    [0036] The invention is described hereinabove by way of example. It is understood that those skilled in the art are able to produce different alternatives of the invention without however leaving the scope of the patent.
