DETAILED DESCRIPTION OF THE INVENTION

(5) In this detailed description, the subject matter flexible big bag (10) is explained with references to examples without forming any restrictive effect only in order to make the subject more understandable.

(6) In order to carry liquid or liquid-based material, a flexible big bag (10) essentially has a first layer (11) which defines a closed volume and wherein essentially the material to be carried is put. The flexible big bag (10) is provided in a form extending horizontally. The flexible big bag (10) has a valve (15) provided on the first layer (11). The process of liquid filling into and discharging from the flexible big bag (10) is realized by means of said valve (15). In the direction of the height of the first layer (11), at least one throttle region (13) is configured in a manner narrowing the cross section of the first layer (11). In the preferred application, pluralities of throttle regions (13) are provided on the first layer (11) at pre-calculated intervals. Various embodiments are provided in relation to formation of throttle region (13) on the first layer (11).

(7) With reference to FIGS. 1a and 1b, there is a ring section (132) provided in a manner encircling the circumference in the direction of the height of the first layer (11) and which forms the throttle region (13) and having a circumference length which is smaller than the length of the circumference length of the first layer (11). The circumference length of the ring section (132) is smaller than the circumference length of the first layer (11). In one of the applications, the circumference length of the ring section (132) is embodied so as to be smaller than the half of the circumference length of the first layer (11). The ring section (132) is made of a narrow woven material which is flexible and which has high resistance. In the preferred application, the material of the ring section (132) is polypropylene woven material. In an alternative application, the ring section (132) can also be made of a rigid or semi-flexible material. The ring section width (W1) is provided between 5 and 10 cm. In the preferred application, the ring section width (W1) is embodied as 5 cm. The ring section (132) throttles specific sections of the first layer (11) and it forms pluralities of carrying compartments (16) inside the flexible big bag (10). Liquid material passage occurs between the carrying compartments (16). The ring sections (132) stay in a free manner after being placed to the circumference of the first layer (11). In other words, there is no connection of the ring section (132) to the first layer (11). In an alternative application, the ring section (132) is connected to the first layer (11). The connection of the ring section (132) to the first layer (11) can be realized by means of seaming. The sections where the ring section (132) throttles the first layer (11) are defined as the throttle region (13). The ring section (132) is provided in a manner shrinking all circumference of the first layer (11) in the same proportion in the direction of the height of the first layer (11). In other words, the ring section (132) throttles both the upper section of the first layer (11) and the section thereof which faces the vehicle chassis or the container, wherein it is carried, in a balanced manner. In this embodiment, the first layer (11) is embodied to be made of plastic-based material. Plastic based material is particularly thermoplastic material. The first layer (11) is particularly made of polyethylene material (PE). In an alternative application of the embodiment, the first layer (11) is made of nylon material. In this embodiment, the first layer (11) is provided at a predetermined thickness and a single layer is sufficient. In the preferred application, the first layer (11) is provided in approximately 1000 micron thickness in a stand-alone manner.

(8) With reference to FIG. 2, in a second embodiment, a second layer (12) is provided at the inner section of the first layer (11) whereon the ring section (132) is provided. In this embodiment, the first layer (11) is made of a flexible narrow woven material. In the preferred application, the material whereof said first material (11) is made is polypropylene woven. The first layer (11) can also be made of PVC and awning materials. PVC can be single-layer or multi-layer composite material. The second layer (12) is embodied to be made of plastic-based material. The plastic-based material is particularly thermoplastic material. The second layer (12) is particularly made of polyethylene material (PE). In an alternative application of the embodiment, the second layer (12) is made of nylon material.

(9) With reference to FIG. 4, also in a third embodiment, there is a second layer (12) provided at the inner section of the first layer (11). The material of the first layer (11) and the material of the second layer (12) are the same as or similar to the material of the second embodiment. The first layer (11) is brought into a form which is throttled at specific intervals from the circumference beforehand, and the flexible big bag (10) is formed in a manner encircling the second layer (12). Throttle regions (13) are formed which are configured in a manner narrowing the cross sectional area of the first layer (11). In the throttle regions (13), there is at least one seaming region (131) which joins the sections where the first layer (11) is folded. In the preferred application, the first layer (11) has seaming regions (131) along the whole circumference in the direction of the height of the first layer (11).

(10) In the second and in the third embodiment, as the first layer (11) is throttled, the sections of the second layer (12), provided in the vicinity of the throttle region (13), are shrank. With reference to FIG. 3a, a protective layer (14) is provided on the second layer (12) when required in accordance with the material whereof the second layer (12) is made. The protective layer (14) is positioned in a manner covering the throttle region (13). The protective layer (14) is provided in a manner encircling the second layer (12) in the vicinity of the throttle region (13) on the face of the second layer (12) facing the first layer (11). With reference to FIG. 3b, since the throttle process on the second layer (12) affects in a wider area than the first layer (11), the protective layer width (W2) of the protective layer (14) is adjusted to be greater than the ring section width (W1). The protective layer width (W2) can be provided between 90 cm and 110 cm. In the preferred application, a protective layer (14), whose protective layer width (W2) is 100 cm, is connected onto the second layer (12) in a manner encircling the second layer (12) in the direction of the height of the second layer (12). As the protective layer (14), a material is used whose tearing resistance is high and which can be connected to the second layer (12). Preferably as the protective layer (14) and as adhesive band and derivatives; adhesive band, reinforced adhesive band are used. The protective layer (14) is adhered in a manner encircling the second layer (12) at the determined width. Moreover, any protective layer (14) can be adhered onto the surface of the second layer (12) by means of double-sided adhesive band or by means of a suitable adhesive. Since protective layer (14) is provided on the second layer (12), the second layer (12) is protected from a tear which is sourced from a probable shrinking. If the material of the second layer (12) does not lead to tearing problem due to the throttle process of the ring section (132), there remains no need to use the protective layer (14).

(11) In the light of the structural details given above, the operation of the invention is as follows. The flexible big bag (10), wherein liquid or liquid based material is filled, is placed to the chassis of a truck-type vehicle or to a container. The flexible big bag (10) can be fixed into the container or into the vehicle chassis. In an alternative application, the flexible big bag (10) is left in a free manner in the vehicle chassis or in the container. By means of the movement of the vehicle, the material provided in the flexible big bag (10) can also be moved in the accelerated movements or in vehicle shakes. The liquid material flows forwardly and begins rising, and the potential energy gained after rising increases exponentially in the return, and the potential energy forms hydrodynamic load. Throttle regions (13) are provided on the first layer (11), and the hydrodynamic load, formed by having carrying compartments (16), returns in a balanced manner, and thanks to the narrowing in the bottle mouth form provided by the throttle regions (13), and the hydrodynamic load is dampened and a balanced wave breaking characteristic is formed. Since throttle regions (13) are formed in the whole circumference of the first layer (11), breaking of the wave is provided in a balanced manner. Since the force, created by the weight of the liquid-based material, acts on the base, the flow which continues on the base side is guided upwardly and wave breaking effect is increased since the base of the flexible big bag (10) is also shrank. Thus, liquid flow is balanced. When the wave formation is prevented or when the wave is broken, the damages like tearing of the seaming sections of the flexible big bag (10) are prevented and driving safety is provided. Moreover, formation of the throttle region (13) by means of interfering to a single layer of the single-piece flexible big bag (10) instead of the methods of joining carrying compartments substantially reduces the labor force proportion.

(12) The protection scope of the present invention is set forth in the annexed Claims and cannot be restricted to the illustrative disclosures given above, under the detailed description. It is because a person skilled in the relevant art can obviously produce similar embodiments under the light of the foregoing disclosures, without departing from the main principles of the present invention.
