A mold is formed the interior volume of which corresponds to the exterior envelope required for the container (2). A core corresponding to the shape required for the cavity (14) to be formed inside the container (2) is prepared. Said core is placed inside the interior volume of the mold and an appropriate plastics material is injected under pressure into said interior volume to constitute an envelope comprising two substantially parallel walls (5, 6) extending at a predetermined small distance from each other between two common lateral edges (9, 10), with a common transverse edge (16) at the same end as the neck (14b). The product to be packaged is injected into the interior of the envelope. The transverse edge (15) of the body (14a) is closed by welding the plastics material.

[ What is claimed is:] [1.] A method of manufacturing a substantially bottle-shaped flat container (1, 2) adapted to contain a small volume sample of a substantially liquid product, the method comprising the step of preparing two walls (1, 2, 3, 4) joined together at their respective longitudinal edges (5, 6, 7, 8), closing a first transverse edge (11, 12), injecting the product to be conditioned into the cavity (13, 14) thus formed, and then closing the second transverse edge (15, 16), characterized in that said method includes the following steps:two half-shells are prepared which are adapted to be pressed together to form a mold the interior volume of which is shaped to form the outer envelope required for said container (1, 2);a core is prepared corresponding to the shape required for the cavity (13, 14) to be formed inside the container (1, 2), the cavity (13, 14) having a body part (13a, 14a) communicating with a neck part (13b, 14b) of smaller size in the transverse direction;said core is placed in the interior volume of said mold and an appropriate plastics material is injected under pressure into said interior volume to constitute an envelope comprising two substantially parallel walls (3, 4; 5, 6) extending at a predetermined small distance from each other between two common lateral edges (7, 8; 9, 10), with a common transverse edge (15, 16) at the same end as the neck (13b, 14b);the product to be packaged is injected into the interior of the envelope;the transverse edge (11, 12) of the body (13a, 14a) is closed by welding the plastics material; and,further characterized in that a thinner transverse line (3a, 4a; 5a, 6a) is formed in each wall (3, 4; 5, 6) of the container (1, 2) at the level of the neck (13a, 14a) to form a break line for opening said container.
