Inliner, composite package and transport container with an inliner, and associated method
View Patent ↗An inliner, for receiving filling material and for being introduced through an opening into a container wall of a transport container, the inliner including shaping rods configured to open with the inliner in the transport container in a direction radially outward of an axis in a manner of an umbrella when the inliner is introduced into the transport container and to close in a direction radially inward of the axis when the inliner is extracted, where the shaping rods are composed of a flexible, resilient material and, as a result of an internal stress, are transferable from a deformed position into a rest position corresponding to the open position of the inliner.
1 . An inliner, configured for receiving filling material and for being introduced through an opening in a container wall of a closed transport container, the inliner comprising:
at least two shaping rods configured to open with the inliner in the transport container in a direction radially outward of an axis when the inliner is introduced into the transport container and to close in a direction radially inward towards the axis when the inliner is extracted,
wherein the at least two shaping rods comprise a flexible, resilient material and, as a result of an internal stress, are transferable from a deformed position into a rest position corresponding to the open position of the inliner,
wherein fixing elements are provided on the inliner for securing the at least two shaping rods at the inliner,
wherein the at least two shaping rods, in the rest position, lie one above the other at at least one point and stretch an area of the inliner at the corners of which area the fixing elements are provided.
2 . The inliner in accordance with claim 1 , wherein the area is configured to cover at least one of an inner surface or a base surface of the transport container.
3 . The inliner in accordance with claim 1 , wherein the at least two shaping rods are glass fibre rods.
4 . The inliner in accordance with claim 1 , wherein the inliner and the at least two shaping rods in the deformed position are configured to be receivable in an application tube, the outer dimensions of the application tube are smaller in cross-section than a filling opening of the transport container.
5 . A composite package configured for introducing an inliner through an opening into a container wall of a transport container, said composite package comprising
an inliner, equipped with at least two shaping rods, in accordance with claim 1 ,
an application tube, in which there are receivable the inliner and the at least two shaping rods in a deformed position, the outer dimensions of the application tube being smaller than a filling opening of the transport container.
6 . The composite package in accordance with claim 5 , further comprising a moulded part configured to fix the inliner after introduction into the transport container at the filling opening thereof.
7 . The composite package in accordance with claim 6 , wherein the moulded part comprises air holes.
8 . A transport container with an the inliner in accordance with claim 1 .
9 . The transport container in accordance with claim 8 , further comprising a filling opening and provided with the inliner arranged in the transport container, the inliner being securable at the filling opening.
10 . A method for introducing the inliner in accordance with claim 1 , into a transport container through an opening in a container wall of the transport container, said method comprising the steps of:
establishing an operative connection between shaping rods and the inliner,
transferring the shaping rods into a deformed position by inserting the shaping rods and the inliner into an application tube,
introducing the application tube with the inliner and the shaping rods received therein through a filling opening into the transport container,
pulling off the application tube while releasing the shaping rods, which thereby stretch the inliner and move to the rest position on an inner surface of the transport container.
11 . The method in accordance with claim 10 , wherein the following steps are carried out to empty the inliner located in the transport container,
removing the filling material,
pulling the inliner upwards to form a sump,
removing the filling material from the sump,
removing the inliner from the transport container.
12 . The method in accordance with claim 11 , wherein the filling material is removed down to a residual quantity of filling material.
13 . The method in accordance with claim 11 , wherein the inliner is pulled upwards to form the sump above the shaping rods.
14 . An inliner, configured for receiving filling material and for being introduced through an opening in a container wall of a closed transport container, the inliner comprising:
at least two shaping rods configured to open with the inliner in the transport container in a direction radially outward of an axis when the inliner is introduced into the transport container and to close in a direction radially inward towards the axis when the inliner is extracted,
wherein the at least two shaping rods comprise a flexible, resilient material and, as a result of an internal stress, are transferable from a deformed position into a rest position corresponding to the open position of the inliner,
wherein fixing elements are provided on the inliner for securing the at least two shaping rods at the inliner,
wherein the at least two shaping rods, in the rest position, lie one above the other at at least one point, are fixed crosswise on the inside or outside of the base of the inliner and stretch an area of the inliner at the corners of which area the fixing elements are provided.
