Inliner of foil material

0001The invention relates to a liner, preferably made of a film material, the like is adjustable in containers such as barrels and and a Filler cap and an example in a wall of the container having usable outlet connection.

0002Inliner the aforementioned type are known and are used for example for receiving liquids or other materials, which are often very gentle and must be aseptically stored and transported in many cases, what to stockpiling possibility of such materials through the liner but also in its emptying or filling particular precautionary measures required to to avoid contamination. This applies in particular if intended for human Consumption provided materials such as to stock fruit juice concentrates are.

0003have liner of conventional design for emptying spout supports from particular a plastic material which is provided with a closing cover and with the are Inlinerwandungsmaterial to connect. Requirements for special hygienic or aseptic Stockholding and transportation, but these are not fulfill. For this purpose it is not enough, such inline with adapted suspend outlet connection irradiation because subsequent manipulations can cause in through the outlet to germs and the like in the can get inline stockpiled product.

0004The risk of germs and the like can enter the stockpiled product, is often caused by damage to the outlet connector on the come.

0005It is therefore an object of the present invention, a liner with an outlet connection to make available, which is highly suitable for human transport consumption provided materials and to stockpile.

0006To achieve this object, the liner of the aforementioned type is characterized from that of the outlet connector a housing with movable support elements for securing the outlet connection has on a container.

0007Thus, a liner is provided which is suitable in highly sensitive Materials to stockpile such as foods and the like and transport, because the housing with the movable grip elements the outlet connection certainly sets on the container so that the risk during transportation is substantially reduced in that the outlet nozzle and thus the liner damage increases with the result that germs can penetrate into the container interior.

0008Preferably, the holding elements are configured as snap elements, so that use of the liner with its outlet connection from the inside in a container is followed in assembly-friendly manner easily into the wall of use container is with immediate assurance of the outlet connection on the Snap closure elements to the container wall. If the outlet connection regions a multi-, preferably octagonal housing form, this can with a adapted to the container ring with appropriate shaping cooperate so that it not only in the longitudinal direction of the outlet pipe in twisting a twist can be shown that the Outlet connector further protects. Preferably, moreover, is a protection device provided, which is open on first use, through a cutting device, which opens the guard on first use, preferably cuts. The protection device is only opened when emptying and a first use of the outlet pipe is pending by the cutter at First use of the outlet pipe and therefore at the beginning of emptying process the liner is activated and open the protective device.

0009Preferably, the nozzle has a closure flap with adapted cutting device, so that the expediently for activation with the shutter, a metered emptying of the liner is formed, the cutter in The opening direction of the protective device is activated. The protective device may, for example, be formed as a membrane and the cutting device as a perforation, the perforated or einschlitzt the membrane. The perforation is preferably integrated into the flap and can by pressing the shutter the guard cut what example via a conventional can be effected leverage mimicry. For this, a lever is operated, the right to the Perforation is connected and the protector cuts. After that can with this lever the closure flap are operated in correspondence the lever position in a sense that the shutter a metered emptying the liner allows.

0010The snap engages expediently a provided on the container Ring formed in polygonal form and therefore not circular is, but as octagonal and with corresponding housing parts of the connecting piece such cooperates that the housing wall with areas within the ring opening lying drain connection can no longer be rotated and axially through the Retaining elements at go fixed äuseseitig specified ring. It should expediently after inserting the nozzle into the housing to the outside projecting housing wall area of ​​the socket, the location within the ring is formed such polygonal corresponding complementary, on the one hand the Widening movement of the resiliently formed holding elements is provided, on the other hand, however, the rotation can be ensured.

0011Further advantages and embodiments of the invention result from additional dependent claims, the following description and the drawing. In the drawing show:<dl tsize="6"><dt>Fig. 1</dt><dd>a perspective view of one embodiment of the discharge pipe an inliner according to the invention;</dd><dt>FIG. 2</dt><dd>a side view of the embodiment of Figure 1,</dd><dt>Fig. 3</dt><dd>a longitudinal sectional view of the embodiment of Figure 1,</dd><dt>Fig. 4</dt><dd>schematically illustrates a container in which the liner is to be inserted, and</dd><dt>Fig. 5</dt><dd>a side view of a container with inserted outlet connection an inliner.</dd></dl>

0012In the drawing, 'basically equivalent parts with matching Reference numerals. The due clarity on the overall presentation the liner has been omitted. However, this is the fundamental Building be designed as conventional and example of a film material exist and have a filling member comprising a conventional rotary shutter. In his lead-out area of ​​the liner with the generally (1) numbered outlet connection provided, of an upper-side edge collar (2) to the generally (3) numbered and having made of a plastic material housing, is to stick with the film material of the liner or to weld and thereafter forming a unit with the liner material to a foil liner with filling rotation lock display and outlet connection, for example, in a container as a barrel made of a plastic material, as shown in Figure 4 is used, can be. The overall aim of such a liner, for example, for storing are used and for the transport of food such as fruit juice concentrate can. The outlet connector (1) has a lever (4) with a generally (5) Marked closure flap is connected, which is to rotate about the lever. On the lever a cutting device (6) is arranged, in the embodiment shown a perforation, which is not shown in a Figure 1, however, 3 visible and there by paragraph (7) cuts amounted Perforationsfolie in figure the not yet cut the outlet connection in or perforated state hermetically shields to the outside, so that special demands on the Sterility of the filled material, for example, the fruit juice concentrate, ensured during storage and transportation in the area of ​​the outlet pipe can be. For this purpose, prior to filling the liner for the aseptic version been sterilized, for example by irradiation with gamma rays, after which the protective device in the form of protective film sterility after Sterilization ensures.

0013As can be seen in more detail from Figure 3, is on the closure cap (5) a cutting device (8) provided in the form of a Perforationsmessers that shown in the Embodiment of Figure 3 in more inactivated state above the Protector (7), that is facing the product inside of the liner, is arranged and with the first operation of the lever (4) or perforated cuts in the protective film (7). This occurs with the first use of the outlet pipe after filling of the liner, that is, when the charged material, such as the Fruit juice concentrate required for subsequent machining or processing becomes. Activation of Perforationsmessers (8) therefore takes place automatically with the Opening of the closure cap (5). After slitting the protective film (7) by means the lever (4) bringing the closure cap (5) in different angular positions become a metered emptying of the liner.

0014As detail is apparent from Figure 4, the container (9), in the use of the liner may be, an outer wall (10) and an opening (11) through which the outlet connection (1) is durchzustecken from the inside. To a corresponding rotation have provided a plastic ring (12) is attached to the outer wall, which is more apparent in Figure 5 in cross section. In the durchsteckbaren Region of the housing (3) are configured as snap elements holding elements (13) provided at By plugging its own resilience the central longitudinal axis of the discharge pipe (1) are moved to and after passing the ring move back and then grab the plastic ring (12). Thus, the outlet connection in the axial direction to the container is fixed. Of the Plastic ring in turn is polygonal, in particular designed octagonal engages with its inner octagonal education in a corresponding outer octagonal design of lying inside the ring housing wall portion of the inserted outlet pipe, so that the basis of this polygonal training the outlet connector and twisting in the housing wall of the container is located so that during the transport or storage of the liner due accruing from outside stresses on the outlet connection not Risk that, for example, due to twisting or axial actuation of the Outlet connection, the connection between the outlet nozzle and liner is damaged with the consequence that germs can penetrate from the outside into the liner interior.
