The invention relates to a yard-type container comprising at least one bellows section in the central part thereof, the height of which can be reduced and likewise the original state thereof reverted to as many times as desired, allowing the reduction of volumes during transportation or storage at the sales point thereof. Similarly, it can also be used as an anti-stress object since the accordion element can contract, expand, and fold as many times as desired without breaking. Furthermore, said contraction allows the variation of the volume of liquid able to be contained in the container. |
