Technical Field

The utility model relates to a packing and filling bag technical field, in particular to size adjustable nodal pattern bag of filling.

Background

Filled bags, containers used by the leading countries in Europe and America to assist in transporting materials. The following alternative names are also known in the transportation and packaging industry: inflatable paper bags, container kraft paper airbags, container slow-inflating bags, inflatable bags, filling air bags, container paper liner bags, container paper air bags, container buffer air bags, container shockproof buffer air bags and the like.

Present disposable filling bag structure variety is various, and during the packing, the packing box is put into to the staff with filling the bag around, can prevent that the goods from producing the collision in the transportation, to the filling bag of rectangle structure, generally comprises the bag body that a plurality of set up side by side, mainly divide into: (1) the interiors are mutually communicated, so that simultaneous inflation can be realized; (2) each bag body is mutually independent and is completely sealed after being inflated; (3) each bag body is independent and is respectively connected with an inflating valve.

In the utility model with patent No. 201420792305.6, a continuous inflatable bag is proposed, the size of which is fixed, so different sizes of packing boxes need to be customized with different types of filling bags, which increases the packing cost of enterprises, meanwhile, the filling bags need to be changed continuously at the packing site during the packing operation, which increases the difficulty of site management; the utility model with patent number 201420129194.0 mentions a fill air pocket, sets up to the nonconformity through revealing two films in the length of bag body during the design, makes the pneumatic valve part easily, but two films still have certain adsorption affinity, can further improve, consequently the utility model discloses developed a size adjustable type fill bag to solve the problem that exists among the prior art, through the retrieval, not discover with the utility model discloses the same or similar technical scheme.

SUMMERY OF THE UTILITY MODEL

The utility model discloses the purpose is: the utility model provides a bag is filled to size adjustable nodal pattern to the fixed problem that brings the enterprise's of packing cost improves and the management degree of difficulty increases of the bag structure of filling among the solution prior art.

The technical scheme of the utility model is that: the utility model provides a bag is filled to big or small adjustable nodal pattern, includes a plurality of bag bodies that set up side by side, and is adjacent be provided with a set of violently heat seal line between the bag body, and is a set of violently be provided with between the heat seal line and tear the dotted line, bag body middle part has the vertical heat seal line that a hot pressing formed along the perpendicular to can tear the direction of dotted line, indulge the heat seal line and separate the bag body for first gas bag and second gas bag, all be provided with the charging connector on first gas bag and the second gas bag.

Preferably, the width of the longitudinal heat-sealing line is 0.8cm to 1.2 cm.

Preferably, the charging connector comprises two films, wherein one end of each film is arranged in the bag body, one end of each film is arranged outside the bag body, a vent hole is formed between the two films, the end parts of the two films, which are positioned outside the bag body, are of right-angled trapezoid structures, and the end parts of the two films are symmetrically attached to each other.

Compared with the prior art, the utility model has the advantages that:

(1) The utility model provides a filling bag with adjustable size, which can be applied to packing boxes with a plurality of sizes to solve the problem that the packing boxes with different sizes need a plurality of types of filling bags; when the filling bag with the largest area is needed, the two filling areas of the first inflating bag and the second inflating bag are filled simultaneously, when the filling bag with the small volume is needed, only one filling area is filled, meanwhile, the first inflating bag and the second inflating bag can be selectively filled at the corners, the whole size is adjustable, and the use is convenient.

(2) The inflation nozzle comprises two films, one ends of the two films are arranged in the bag body, the other ends of the two films are arranged outside the bag body, an air vent is arranged between the two films, the end parts of the two films positioned outside the bag body are in a right-angled trapezoid structure, and the end parts of the two films are symmetrically attached, so that the two films are more convenient to separate, an external inflation device is inserted, and air is admitted from the air vent; meanwhile, the specifications of the two films are the same, and the manufacture is also convenient.

Drawings

the invention will be further described with reference to the following drawings and examples:

Fig. 1 is a schematic view of the structure of the present invention;

FIG. 2 is a schematic view of the arrangement of two sheets of the film according to the present invention;

Fig. 3 is a schematic diagram of the structure for protecting the corners of the edge.

wherein: 1. the bag comprises a bag body, 2 transverse heat sealing lines, 3 tearable dotted lines, 4 longitudinal heat sealing lines, 5 first inflatable bags, 6 second inflatable bags, 7 inflation nozzles, 8 films.

Detailed Description

The following detailed description is made in conjunction with specific embodiments of the present invention:

As shown in figure 1-2, the size-adjustable filling bag comprises a plurality of bag bodies 1 which are arranged in parallel, a group of transverse heat sealing lines 2 are arranged between the adjacent bag bodies 1, a tearing dotted line 3 is arranged between the group of transverse heat sealing lines 2, a longitudinal heat sealing line 4 formed by hot pressing is arranged in the middle of each bag body 1 along the direction vertical to the tearing dotted line 3, the width of the longitudinal heat sealing line 4 is 0.8 cm-1.2 cm, this vertical heat-seal line 4 separates the bag body for first air bag 5 and second air bag 6, all is provided with charging connector 7 on first air bag 5 and the second air bag 6, and charging connector 7 includes two films 8, and 8 one ends of two films set up in bag body 1, and one end setting is outside at bag body 1, has a blow vent between two films 8, and two 8 tip of film that are in bag body 1 outside are right trapezoid structure, and the setting of laminating of 8 tip symmetries of two films.
