Abstract

The technical problem of producing, that is to say filling and closing, water-tight sacks at any desired site consists in the impossibility of having machinery available at any desired site. The object is achieved in that completely sealed sacks are produced which allow subsequent filling. This is achieved in that a remaining filling aperture is extended down to the lowest point (similar to a trunk). The water contained presses simultaneously outwards and inwards onto the "trunk" so that backflow is suppressed. The contents are trapped without further manipulation being required. Storable and stackable in any position. Therefore particularly useful for damming in the case of flood risk and transportation in means of transport (such as helicopters) which are not suitable for liquids for the targeted "bombing" of forest and ground fires.

Description

Koog - sack

The invention relates to the Koog sack, the filled water without further action beyond the filling indicates that the filled Water is captured immediately with no additional effort or means.

The previously known techniques, sandbags, their production if necessary Very complex due to transport and auxiliary workers, the production on stock storage difficulties and causes rotting of the casing material.

The aim of the invention is to create a container which does not require sewing is ready for use.

According to the invention, the object is achieved in that the pattern of the water bag tapers towards the opening towards the hose (Figure Number 1). By returning the opening to the bottom of the bag and the locking of the Opening at the bottom of the sack by means of a s-sheet (Figure 2) becomes a shift avoided. The recirculated opening cannot be seen from the outside, rather it is visible just a normal bag opening. The water is poured into this visible opening in the sack filled in and flow into the sack up to the full displacement possibility. Possible Air congestion formed in the bag space escapes through a finger-thick tube which after venting is stuffed into the sack with a finger. The 3 own Water pressure that presses on the filling hose and the venting device prevents the filling water from leaking out. That is enough to empty the Koog sack Introducing a and for unlocking and pulling out the filler hose from the Sack, the water flows out, the sack can be stored in a space-saving manner for the next use will.

The applicability of this invention lends itself to demarcation, containment of water or other liquid.

For example, risk of flooding.

The advantage of this invention is that the harassing water even the; let supplies for their own containment, sufficient and free of charge.

The place of water is interchangeable with the place of liquid.

The drawing shows: FIG. 1 in the state for use for emptying Fig. 2 a) in the rest or storage state b) in the state ready to take up liquid Fig. 3 illustrates the sack bottom fold in which the hole for the introduction of the S-hook located.

Figure 4 shows the pattern for an endless belt.
