<p>Semi-collapsible containers (10) have a side wall, which includes the upper part (5), the middle part (6) and bottom (7), and also has a base (8). The middle part (6) contains a vacuum-operated, part of a panel having a control section (2) and the initiation section (1). Control section (2) is considering steeper in the vertical direction, this means that the acute angle in relation to the longitudinal axis of the container (10) as an initiation section (1). Based on the presence of a vacuum force in the container when the vacuum force is developed due to the cooling of hot liquid in the container (10), will be an initiation section (1) fold inwards, thereby induce roll control section (2) and continued towards further folding inside the container (10), resulting folded in the middle section (6). In the folded state may be in the upper middle part (6) in substantial contact with the lower part (6) while maintaining the saturation capacity of the container (10). Raised ribs (3) generate additional support in the container in its folded form. In another embodiment, the telescopic container returns to its original position when vacuum is released after removal of the container-closure.</p> |
