GR20190100176A - Big-sized propylene sac for the transport of bulk materials released with the hand or from a distance with use of a string or remote control - Google Patents

Abstract

The invention relates to a big-sized sac which is transportable by crane and meant for the transport and deposition of even voluminous materials. The deposition is achieved due to the easy opening of the sac’s base by mere unfastening of two strings (fig.1,2). The sac is one meter long, one meter wide and one meter high.

Description

DESCRIPTION

HUGE BAG

WITH EASY OPENING OF ITS ENTIRE BASE

The base of the "Megabag with easy opening of its entire base" is divided by its construction into four table shapes (PICTURE 1, unfolded). In each of the positions with no. (7), (8) and (9) of the three trapezes each has a hole, while a cord (no. 6) has been fitted to the top of the small base of the fourth trapeze. The cord (6) passes through the holes (7,8,9) of the "Megabag with easy opening of its entire base" in order to close it before loading the materials to be transported, as follows:

First we pass the string (6) through the hole (7), then through the hole (8) and finally through the hole (9). We pull the string making sure that all four of the above table shapes are with the closure inside the "Megabag with easy opening of its entire base", so that no part of the tables hangs outside of it. This is how the "Megabag with easy opening of its entire base" closes. Then we tie together (10) the cord (6) to another cord (5), fitted externally on the same side of the "Megabag with easy opening of its entire base". The "Megabag with easy opening of its entire base" is closed and we fill it with materials. After filling it, we adjust the retaining straps (1,2, 3,4) that are in the four corners of the upper part of the "Megabag with easy opening of its entire base" on a crane and carry it wherever we want. After it has been transported to the place of deposit of the materials, we untie the tie (10) of the two strings tied together (6 and 5) and, due to the weight of the materials, the entire underside of the "Megabag with easy opening of its entire base" opens and falls the materials we have deposited in him.

Claims (2)

"HUGE BAG WITH EASY OPENING OF ITS ENTIRE BASE" The common commercial polypropylene megabag usually measures 1 m X 1 m X 1 m (ie 1 cubic meter volume) and does not open at the bottom. There are mega bags that only open a part in the center of their base, but they are not suitable for the transport of bulky objects, eg firewood, which cannot pass through the existing holes, only small-caliber materials eg sand. The "Megabag with easy opening of its entire base" is characterized by a different development (DRAWING 1), and by the fact that its entire base opens easily (DRAWING 2). 1) DEVELOPMENT SHAPE "Big bag with easy opening of its entire base" The development of the "Megabag with easy opening of its entire base" is shown in PICTURE 1. It is a rectangular sheet of resistant polypropylene, with a total area of six square meters and specifically with dimensions of the large side of the rectangle four meters and the small side of the rectangle one and a half meters. Four right-angled isosceles triangles (DRAW 1 : i, ii, iii, iv) have been cut and removed from this sheet, with the length of the equal sides 0.50 meters and the base of each 0.71 meters. 2) CLOSING "Big bag with easy opening of its entire base" First we pass the string (6) through the hole (7), then through the hole (8) and finally through the hole (9). We pull the string (6) making sure that all four table shapes of the base are inside the megabag, so that no part of the tables hangs down. This is how the "Megabag with easy opening of its entire base" closes. It opens by untying the tie (10) of the two strings (6 and 5) tied together and, due to their weight, the materials, even if they are bulky (eg firewood) fall to the deposit point.
