ABSTRACT:
The container of flexible or semi-rigid material is adapted to receive a liquid such as a maintenance product and has two planar bearing sides 2 for bearing against a support plane 4, these sides forming a dihedron whose angle .alpha. is less than 90.degree. when the container is filled with liquid and has its normal shape. The two halves 1 of the container are fixed together along a rigid assembly bead 3 and the container has spherical bulging portions 7 for closing the container. The container outlet is at the end opposite the apex of the dihedron and arranged so it is always above the liquid maximum level in the container when it is resting on one of the bearing sides.
