Abstract

A packaging bag with a #-shaped bag bottom comprises a square woven bag body defined by an upper cover, the lower bottom and four side walls. A cylindrical feed port is formed in the upper cover. The lower bottom is a closed flat bottom surface. Woven belts are perpendicularly sown downwards along the two sides of each side wall of the bag body, and the portions, located at the upper edges of the adjacent lateral sides of every two adjacent side walls, of the two woven belts form an annular hanging belt above the corresponding corner of the bag body. The woven belts are sown on the inner side wall or the outer side wall of the bag body. Upper end surrounding belts are sown on the upper portions of the four side walls of the bag body. A middle surrounding belt is at least sown on the middles of the four side walls of the bag body. The upper end surrounding belts and the middle surrounding belt are connected to the woven belts in a pressing mode respectively to form a #-shaped connecting belt structure, wherein the woven belts are perpendicularly sown downwards along the side walls of the bag body to form the four hanging belts. The packaging bag has the advantages that the packaging bag is reasonable in structure, safe and reliable to use, high in firmness, smooth in feed and discharge and not prone to partial swelling phenomenon, less workers stack small packages, labor cost is reduced, transporting and stacking are convenient, the repeated utilization rate of tons of package bags is increased, and packaging cost is saved.

Description

The groined type packaging bag of revealing all the details

Technical field

The utility model relates to a kind of for loading a large amount of pressed powders or particulate matter, the packaging bag of revealing all the details of the groined type of being convenient to lifting, belong to packaging bag technical field.

Background technology

Ton packaging bag is exactly to load 500-1000Kg pressed powder or particulate matter as its name suggests, to lift the packaging bag of movement.The bag of most ton packaging bag is at present shaped as cuboid, and if length and width is respectively 900mm, height is 1250mm, respectively has up and down the charging and discharging mouth of a tubular, is convenient to tying; The packaging bag of this ton is because having loaded a large amount of bulk solid powder or particulate matter, and therefore the fastness of its bag of body is quite important, comprises bag suspension ring that make on body top; Also require in addition the input and output material of ton packaging bag conveniently, reliably, but owing to being subject to the restriction of structure, existing ton strap also exists unreasonable structure, fastness is not good, and input and output material is obstructed, easily produces the problems such as bulge phenomenon.

Summary of the invention

The purpose of this utility model is to overcome the deficiency that prior art exists, and provides a kind of rational in infrastructure, safe and reliable, and fastness is good, and input and output material is unobstructed, the groined type that is not the prone to local bulge phenomenon packaging bag of revealing all the details.

The purpose of this utility model completes by following technical solution, the packaging bag of revealing all the details of a kind of groined type, it comprises a upper cover, go to the bottom and four side perisporiums enclose the square weave bag forming, on described, cover and be provided with columnar discharging opening, go to the bottom as the planar base surface of sealing, on four sidewalls of described bag, be respectively sewed with vertically downward braid along both sides, two adjacent walls form ring-type along two braids that prolong in adjacent side respectively and form suspender belt above bag bight, and described braid is made on the madial wall of bag or on lateral wall; On the sidewall of four directions, described bag top, be sewed with upper end shroud, shroud be at least sewed with one on the cubic sidewall in the centre of bag in the middle of, and shroud box middle shroud in described upper end is crimped on respectively described four suspender belts and makes vertically downward on the braid on bag sidewall, and form groined type connection banded structure.

Described braid is made on the lateral wall of bag; The braid of making on described four sidewalls respectively extends downward the bottom surface of going to the bottom, and braid facing each other is seamed in together on bottom surface, forms the groined type braid structure of bottom surface; On the inwall of described bag, scribble one deck insurance film or diaphragm seal; On described big open end, be upwards provided with the soft bundle sack that can tie up sealing.

The utlity model has rational in infrastructurely, safe and reliable, fastness is good, and input and output material is unobstructed, be not prone to local bulge phenomenon, reduce the code bag number that uses inner wrapping, reduce cost of labor, convenient carrying, code bag, improve the recycling rate of waterused of ton packaging bag, saves the features such as packing cost.

Brief description of the drawings

Fig. 1 is structural representation of the present utility model.

Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is described in detail: shown in Fig. 1, a kind of groined type described in the utility model packaging bag of revealing all the details, it comprises a upper cover 1, go to the bottom 2 and four side perisporium enclose the square weave bag 3 forming, on described upper cover 1, be provided with columnar inlet point 4,2 planar base surfaces for sealing of going to the bottom; On four sidewalls of described bag 3, be respectively sewed with vertically downward braid 5 along both sides, two adjacent walls form ring-type along two braids that prolong in adjacent side respectively and form suspender belt 6 above bag bight, and described braid 5 is made on the madial wall of bag 3 or on lateral wall; On described bag 3 four directions, top sidewalls, be sewed with upper end shroud 7, shroud 8 be at least sewed with one on the cubic sidewall in the centre of bag 3 in the middle of, and described upper end shroud 7 and middle shroud 8 are crimped on respectively described four suspender belts 6 and make vertically downward on the braid 5 on bag sidewall, and form groined type connection banded structure; Described four suspender belts 6 have loaded the square package bag of a large amount of pressed powders or particulate matter for handling appliance handlings such as cranes.

Shown in figure, described braid 5 is made on the lateral wall of bag 3; The braid 5 of making on described four sidewalls respectively extends downward 2 the bottom surface of going to the bottom, and braid facing each other 5 is seamed in together on bottom surface, forms the groined type braid structure of bottom surface, and this structure has improved the use fastness of suspender belt greatly; On the inwall of described bag 3, scribble one deck insurance film or diaphragm seal; So that the pressed powder of interior loading or particulate matter store.
