A squeezeable container for media of pasty or creamy consistency and high-viscous fluids, made of thin-walled, extruded plastic. The container has a slit-shaped discharge opening (Fig. 1a pos. 3, Fig. 2a pos. 5, Fig 3a pos. 5, Fig. 4a pos 5 and Fig 5a pos. 4) through which the content can be squeezed out. The opening may also be prepared, or it can be produced e.g. by cutting off a corner (Fig. 1 and Fig. 2) or a strip (Fig. 3, Fig. 4 and Fig. 5) of the container. On the inside of the container walls are linear protrusions (Fig. 1 pos. 1, Fig. 2 pos. 1, Fig. 3 pos. 1, Fig. 4 pos. 1 and Fig. 5 pos. 1) with such a profile that protrusions in one portion of the container wall can engage in the protrusions of an opposite portion (tongue-in-groove engagement) and thereby close the discharge opening when the container walls are squeezed together. The invention further comprises variants with a discharge channel (Fig. 2 pos. 3 and Fig. 2a pos. 3) or a discharge funnel (Fig. 3 pos. 2 and Fig. 4 pos. 2), established by means of sealed seams in the area of the container walls adjoining the discharge opening. The container can be made from extruded tube which is sealed at the ends (Fig. 1 pos. 2 and Fig. 2 pos. 4) or from strips, sealed along the edges (Fig. 3 pos. 4, Fig. 4 pos. 4 and Fig. 5 pos. 2). |
