Description

Y — A flexible bulk container flap for discharge spout Full description

background of the invention

The present invention relates to a large flexible container for use in the transportation of bulk materials. It relates in particular

The container is of the type commonly known as big bags.

The transportation of solids; usually in the form of powders; Lila is important in the modern industry. This is particularly the case with the manufacture of an excess number of materials used as part of the

The process or that is sold as a final product by specialized companies far from the place where it is done

final processing or packaging. Some materials need to be protected from moisture during transportation

The environment they provide, commonly referred to as big bags, is ideal.

Such large bags are flexible containers which can contain volumes from 0 to about 5 to ? tons of matter. Most of the bag is typically made of PVC and reinforced

With a polyester base woven fabric.

The bags have a number of benefits. eg are reused and can be kept based

It can be easily operated with actual repairs made using a relatively simple set of materials

and tools. Furthermore it; When the bags are unloaded, they can be folded into a relatively small space. This vo _last attribute reduces the amount of storage required in Alls when the bags are not used or when they are required to be returned

to the financier.

s

However, big bags have a number of disadvantages inherent in their design.

The main drawback is that the outlet of the bag is typically at the bottom surface of the bag. and includes

The outlet is on a material intake sleeve or discharge tube which is simply an extension of material

The bag is in the form of a cylinder that connects the goods to the bag with the outer medium. As can already be deduced, the pressure at the exit exerted by the goods is great and must be taken into account

Ensure that the discharge tube is properly arranged to prevent unwanted material loss.

Another disadvantage of these bags is that the operator must be careful when emptying them

Goods out of the bag. typical for unloading goods; The playlist will run after installing the rope around

The outlet neck of the discharge tube to control the flow cuts the band holding the discharge tube in the 0 closed state. Once the ligatures have been cut and the Ja fixation is resolved, the cargo is compressed onto the tube

Unloading can lead to rapid unloading of goods. If the correct procedure is not followed the existing one

On operation it can potentially surprise the outflow of materials. It is known as Lad

Materials blocking the discharge pipe, in which case the blockage may need to be removed from the incumbent

Operation is to be at the bottom of the bag to do this process manually. A widely used alternative 1 to avoid the operator going down and into such danger is to simply strike the discharge pipe

dead end by any means close.

EP No. 1595995751 discloses a bag with a flat base ¢ that is drawn

via the upward discharge tube on the existing base; The flap secures the discharge tube

It prevents the material from flowing out of the bag.

— P — EP No. 00106 discloses a cyst with a flat bottom; The flap is pulled through the discharge tube in the base to secure the contents; The tongue 180 is fixed in. The object of the present invention is to improve upon prior art bags and comprise a higher level 6 of functionality and safety. GENERAL DESCRIPTION OF THE INVENTION According to the invention a flexible bulk container of gall container having a body portion defining the volume is provided in which the goods are kept and transported from a first location to a second location; The body part shall include an entrance enabling goods to be loaded into the body part; 0 The base of the body part shall be a frusto-conical ¢ The container also includes a flexible DED tube hanging from the base of the body part to hold cargo so that it can be emptied into the body part; and a locking tab closure flap, fixed to the first end of the body part and unloadable at the second end of the securing device on the body part; the flap vo, interstitially affixed, passes and carries the discharge tube when goods are retained; the body part also includes a means A second fixation to which the second end of the tongue is detachably fixed so that the tongue is held clear of the discharge tube when goods are unloaded.

__ M _ The bag provides controlled unloading of the contents of the bag and also to achieve retention of the contents when transporting and storing. and the discharge tube shall be provided with a closing device for vacuum-sealing the discharge tube; Said closing means are A rope and padlock; The locking mechanism is released by pulling the cord. The Lad allows the contents of the big bag to be released by the emptying mechanism without the need for the operator to go down the bottom of the bag. The first end of the 1:4 sealing cap is preferred to be combined with the body part. This feature allows the flap to be firmly held and made more able to withstand the force exerted on the flap by the contents of the container .container 0 . It is useful for the flap to be triangular in shape and attached at one end to the base of the container. And the features of the tongue flap increase its strength; The material used reduces and makes it easier to hold the tongue in place. The vacuum tube is optionally formed from bi-layer material to increase the durability of the vacuum tube and to enable the vacuum tube to interlock more easily with specific containers into which larger bag contents are emptied. The inner layer is optionally also longer than the outer layer and extends to 1 behind the outer layer; To reduce dust emissions into the atmosphere. It is preferable for the second end of the closure flap to have a tape attached to it. Said flap is SUG for attachment to the first and second fasteners and allows the operator to easily pull the closure flap through the discharge tube without having to slide down the bag. and so

The other end is welded to the body part, the base, and the base part, 01 frusto-conical, is attached to the part with the base, which is in the form of an incomplete cone. In controlling the flow of material outside the base section 11. The conical shape of the base part. the two layers; If necessary; From the VA to the outlet, empty the bag with minimal dust release. Unloading facilities may be configured such that the contents of the bags are emptied into a metal conduit; The metal pipe passes between the inner sleeve

M - for the VA outlet and the external sleeve for the outlet 14, and the sleeve sleeve 017 is installed in place around the pipe to reduce dust emitted to the surrounding medium. The double layer arrangement has the generally useful additional benefit that most wear is caused by contents flowing out of the bag. 01 The double layer sleeve can therefore extend the life of the bag. When bag 01 is filled, bag 01 is unfolded from the flat storage formation. The lifting ring assembly is installed under the wire in the 1” rim of the 1:0 AY cap and bag 01 is raised until the 11 inlet sleeve can be located around the discharge tube of the hopper containing the material to be loaded into The bag 01. The quantity sleeve of the outlet 17 is fixed using binding rolls formed of plastics material, and then the bag dus 01 0 is attached to the quantity sleeve of the inlet 11. After that Transfer the loaded bag 01 to the desired location and the process is done in the reverse order.

Figures TY) through 'uh) show a typical locking mechanism; It is well known in CLL and can be used as part of rope and lock mechanism. The AN has two components: a 101 receiving member (shown in Figures D; E in front and side projection respectively) and a VY key (shown in Figures JV C in front and side projection 0; and back respectively). when using a rope (not shown); which is tied around the discharge pipe” passes through the VY slot of the receiver member Ve The position of the pin key 0 in the receiver member VY holds the rope against the receiver member and prevents its movement without intervention on the part of the operator. The serrated edges 77 of the key 71 prevent the lifting of the key 71, which thus loosens the rope and leaves it free to move. By means of the above mechanism incorporating the remote movement of the ARE VY pin in the Ve receive member, the operator can loosen and tighten the rope around the tube.

The discharge is thus flow controlled. if required or appropriate; The outlet sleeve sleeve can be formed to have a single layer. For example in those cases where the outlet sleeve does not pass around the metal tube, a single layer is sufficient. The advantage of a single layer is that the structure of a single layer outlet is simpler than a two layer outlet. And the reforms being made are facilitated

For the outlet where there is only one layer. The length of the outlet can be chosen to suit a specific purpose. It must be understood that the invention does not limit itself to the specific details described in the call, which are illustrated by example only; Numerous modifications and changes can be made within the scope of subsequent claims.
