Bulk bag with stand type pulling up rings

Abstract

Disclosed is a bulk bag having self-standing loops. The bulk bag is configured with a bag-shaped body having a reversed “U”-shaped loop protruding upwardly from an outside thereof and configured to flexibly stand upright by itself from a folded position upon unstacking of bodies, wherein the loop is coupled to the body at a position spaced downwardly apart from a top edge of the body by a predetermined distance, the loop having an air tube having a predetermined length and coupled to an outside of the loop. The loop is configured with a semicircular arc-shaped hook portion and “I”-shaped supporting portions respectively extending from opposite ends of the hook portion, and the air tube is coupled with the hook portion and an at least one supporting portion and is heat-treated and flexibly bent at a portion corresponding to a boundary point between the hook portion and the supporting portion.

Description

TECHNICAL FIELD[0001]The present invention relates generally to a bulk bag having self-standing loops. More particularly, the present invention relates to a bulk bag having self-standing loops, wherein the loops are configured to flexibly stand upright by themselves upon unstacking of the bulk bag.BACKGROUND ART[0002]As well known in the art, a bulk bag is a large bag that is used to load and transport various types of bulk products such as fertilizers, grains, minerals, and compounds, and is also known as a flexible intermediate bulk container (FIBC), a ton bag, a big bag, a super bag, etc.[0003]Such a bulk bag, which is currently on the market, is made from a flexible material such as fabric, etc. and is configured with loops secured to a side portion of a body thereof. The bulk bag allows a forklift operator to insert forklift forks into the loops so as to be lifted thereby.[0004]Meanwhile, the loops are also made from fabric and thus tend to sag down or folded over on themselves...

AI Technical Summary

Benefits of technology

The present invention is about a new design for a bulk bag with a loop that allows it to stand upright on its own. This makes it easier and safer to work with and also makes it commercially available immediately. The loop is attached to the body of the bag and extends from the top edge by a specific distance. This allows multiple bulk bags that are not fully filled to be stacked and then unstacked with the loop remaining upright, leading to improved efficiency.

Problems solved by technology

Meanwhile, the loops are also made from fabric and thus tend to sag down or folded over on themselves.

Accordingly, it requires much manual work in order to insert or release the forklift forks into or from the loops, causing work accidents to occur often.

However, in view of the fact that the tone bag having existing problems is used, the flexible seam material 30 to be applied to the cited invention may not easy to develop.

Thus, there is a problem in that when multiple cited inventions are stacked and then are unstacked, the multiple loop means 20 may not be properly erected from a folded position to an upright position.
