Abstract

The invention provides a gridded-bottom packaging bag. The gridded-bottom packaging bag comprises an upper cover, a bottom and a square woven bag body formed by combining the peripheral walls of the four sides; a cylindrical discharge hole is formed in the upper cover; the bottom is a closed flat bottom surface; woven belts are sewn at the two sides of each of the four sidewalls of the bag body vertically and downwards; the upper ends of two woven belts on every two adjacent sidewalls close to the jointed edge of the adjacent sidewalls are formed into a ring serving as a hanging belt above the corresponding corner of the bag body; the woven belts are sewn on the inner sidewalls or the outer sidewalls of the bag body; an upper-end surrounding belt is sewn to the tops of the sidewalls of the four sides of the bag body, and at least one middle surrounding belt is sewn to the middle parts of the sidewalls of the four sides of the bag body, and the upper-end surrounding belt and the middle surrounding belt are crimped on the four hanging belts and sewn to the woven belts on the sidewalls of the bag body vertically and downwards, and therefore, a gridded connecting belt structure is formed. The gridded-bottom packaging bag is reasonable in structure, safe and reliable to use, good in firmness, smooth in feeding and discharging materials and not prone to swell locally; as a result, the number of people for stacking small packages is reduced and the labor cost is reduced; the gridded-bottom packaging bag is convenient to carry and stack; besides, the reutilization rate of the ton packaging bag is increased and the packaging cost can be saved.

Description

The packaging bag of revealing all the details of a kind of groined type

Technical field

The present invention relates to be 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, so 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 object of the invention is to overcome the deficiency that prior art exists, and provide a kind of rational in infrastructure, safe and reliable, 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 object of the invention is to complete 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, each is sewed with braid vertically downward 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 present invention has rational in infrastructure, safe and reliable, and fastness is good, and input and output material is unobstructed, be not prone to local bulge phenomenon, reduce the code bag number of using 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.

Accompanying drawing explanation

Fig. 1 is structural representation of the present invention.

The specific embodiment

Below in conjunction with accompanying drawing, the present invention will be described in detail: shown in Fig. 1, a kind of groined type of the present invention packaging bag of revealing all the details, it comprises a upper cover 1, the 2 and four side perisporiums of going to the bottom 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, each is sewed with braid 5 vertically downward 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.
