Den foreliggende opfindelse angår en fleksibel beholder til transport og lagring af gods og med en kappe-, en bund samt en påfyldningsåbning, hvilken beholder har løfteøjer til løftning af beholderen, hvilke løfteøjer er dannet af direkte forlængelser af den øverste del 5 af beholderens kappe.The present invention relates to a flexible container for transporting and storing goods and having a jacket, a bottom and a filling opening, which container has lifting eyes for lifting the container, which lifting eyes are formed by direct extensions of the upper part 5 of the container sheath.

Sådanne beholdere eller store sække anvendes til transport og lagring af gods, og godsmængden varierer almindeligvis fra nogle hundrede kg til flere tons. Sådanne store sække er hidtil blevet fremstillet ved, at et materialestykke er blevet lagt dobbelt, og det således sammen-10 lagte materialestykke er blevet sømmet sammen ved den øverste ende, som samtidig danner den store sæks løfteøje eller løfteøjer. Eftersom sømmen på sådanne store sække passerer netop på det sted, som ved løftning af sækken, fx ved hjælp af en løftekrog, udsættes for de største belastninger, er sådanne store sække tilbøjelige til at gå i 15 stykker langs sømmen på løfteøjerne.Such containers or large bags are used for transport and storage of goods, and the amount of goods usually varies from a few hundred kg to several tons. Such large sacks have hitherto been made by a double piece of material, and the piece of material thus assembled has been seamed together at the upper end, which at the same time forms the lifting eye or lifting eyes of the large bag. Since the seams of such large sacks pass precisely at the place which, when lifting the sack, for example by means of a lifting hook, is subjected to the greatest loads, such large sacks tend to go into 15 pieces along the seam of the lifting eyes.

Fleksible beholdere eller store sække kan, som det er kendt, også fremstilles af et slagfast emne, hvis øverste del og naturligvis også den nederste del dannes af ensartet sammenhængende materiale. Sådanne store sække fordrer lodrette sømme, hvorfor konstruktionen af denne 20 grund har ringe holdbarhed. En sådan konstruktion findes beskrevet i dansk fremlæggelsesskrift nr. 153.936. For at kunne fremstille selv overordentligt store sække af et sådant slagfast emne med hel øverste ende skal også det slagfaste emnes diameter være overordentlig stor.As is known, flexible containers or large sacks can also be made of a impact-resistant blank, the upper part and, of course, the lower part also being formed of uniformly coherent material. Such large sacks require vertical seams, which is why the construction for this reason has poor durability. Such a construction is described in Danish Patent Publication No. 153,936. In order to be able to manufacture even extremely large bags of such impact-resistant workpiece with the entire upper end, the diameter of the impact-resistant workpiece must also be extremely large.

I den fra ovennævnte danske fremlæggelsesskrift kendte beholder er 25 beholderens øverste del syet sammen på steder, som danner beholderens løfteøjer, og som følgelig, når den fyldte beholder løftes, udsættes for store belastninger. Som følge af sammensyningen af beholderens øverste del, svækkes beholderens bæreevne imidlertid væsentligt som anført i fremlæggelsesskriftet sammenlignet med materialestyrken af 30 det materiale, af hvilket beholderen er fremstillet.In the container known from the above-mentioned Danish publication specification, the upper part of the container is sewn together in places which form the lifting eyes of the container and, consequently, when the filled container is lifted, are subjected to heavy loads. However, as a result of the stitching of the upper part of the container, the carrying capacity of the container is substantially weakened as stated in the presentation specification compared to the material strength of the material from which the container is made.

Formålet med opfindelsen er at tilvejebringe en fleksibel beholder, som kan fremstilles af et slagfast emne på en sådan måde, at den fleksible beholders løfteøjer på pålidelig måde kan modstå alle de store belastninger, som løfteøjerne i praksis kan udsættes for.The object of the invention is to provide a flexible container which can be made of a impact-resistant workpiece in such a way that the lifting eyes of the flexible container can reliably withstand all the large loads to which the lifting eyes can in practice be subjected.
