Definitions

  • the present invention relates to containers or bags capable of containing from 100 kg to several tonnes of bulk materials, in particular fluent, pulverulent or granular materials.
  • Some of these bags are shaped so as to present at their top one or two lifting loops forming an integral part of the walls of the bag; a filling slot is provided between the loops, when they are two in number.
  • Other bags are provided at their top with at least one lifting handle attached to the bag, more generally from two to four added handles.
  • the lifting loops or handles allow the bag to be handled by lifting devices (forklifts or cranes) provided with arms or hooks, which are engaged in these loops or handles.
  • This process is handcrafted, insecure, the strap can be untied, and it represents a waste of time during handling.
  • the present invention aims to overcome the risks and disadvantages mentioned above. To this end, it relates to a container provided with integrated lifting loops or attached lifting handles, characterized in that it comprises a gripping ring, in which said loops or handles are passed and which is an integral part of the content, having been put in place when it was made.
  • a container is thus obtained having a single and convenient point of gripping, which facilitates the work of the handler and ensures rapid and reliable handling of the containers, the weight of which is in this way well distributed over all the loops or handles during the stroke of the which are practically no longer at risk of being damaged.
  • This ring remains useful when the container has only one large loop or lifting loop.
  • the containers or bags considered can be made of polypropylene strip fabric, coated or uncoated canvas and generally any natural, artificial or synthetic woven fiber.
  • the ring must, of course, have a solidity in relation to the weight of the loaded bag. This solidity depends on the nature of the material which constitutes it and its thickness.
  • the ring can be of any metal or any molded plastic material having sufficient mechanical strength; it can also be made from straps or ropes of any material, natural (for example sisal, jute, cotton), artificial (for example viscose), or synthetic (for example polyamide, polyethylene, polypropylene, acrylic resin). When is made with strap, it can be in a single thickness or be wound on itself two or more times.
  • seams joining the two superimposed ends on several centimeters of the rope or strap or joining the overlapping thicknesses of the strap wound on itself these seams can be transverse and / or longitudinal; in the latter case they are marginal and possibly evenly distributed over the width of the ring. Any other connection means is possible.
  • the invention also relates to the method of manufacturing the container.
  • the ring When the ring is formed in advance in any of the abovementioned materials, it must be passed through by the deployed lifting loops or handles of the container, before finishing making it.
  • a ring formed on the bag from a rope or strap band, which is passed through the loops or lifting handles of the bag, which is wound on itself at least once and which is looped through transverse and / or longitudinal seams, in order to obtain a ring in which said loops or handles are engaged and assembled.
  • Figure 3 shows a bag 1 consisting of a piece of flexible material folded along 2. The two folds are sewn laterally at 3 and at the bottom to close the bag. The side seams are stopped at a certain distance from the fold 2 and a filling slot 4 is formed by cutting towards the middle of the fold 2, which gives rise to the top of the bag with two loops of leva ge 5, in which the arm or hook of a lifting device is usually engaged for handling the bag.
  • the bag is completed by a gripping ring 6a ( Figure 1), consisting of a strap, which has been engaged in the lifting loops 5, has been optionally wound several times on itself, two or three times for example - so that the ring has sufficient thickness and solidity, depending on the weight of the bag filled, then which has been closed with marginal seams 7 (seams and stitches for example), possibly by others longitudinal seams and by transverse seams, these seams being limited to the region of the two ends superimposed on several centimeters of the strap, or being extended to the entire length of the strap, when the latter has been wound several times on itself .
  • marginal seams 7 seams and stitches for example
  • the ring 6b is made of metal or molded plastic. It is not possible to place it on the finished bag. In this case, the deployed bag is engaged in the ring, before making the side seams 3 and the bottom seam, until the ring is in the region of the fold 2 of the bag. Then we finish. making the bag.
  • the hook 8 of a crane easily engages in the ring 6a or 6b, with the above-mentioned advantages.
