Description

Multi-cavity vacuum-pumping packaging bag

Technical Field

The utility model relates to the technical field of packaging bags, in particular to a multi-cavity vacuumizing packaging bag.

Background

The packaging bag is a bag for packaging various articles, so that the goods are convenient to transport and easy to store in the production flow process. Is widely used in daily life and industrial production. The rice packaging bags are common, the existing rice packaging bags are generally packaged in a vacuumizing mode and used for prolonging the shelf life, but after granular easily-rotten products such as the existing rice are packaged in a vacuum mode, the surfaces of the packaging bags are uneven, attractive in appearance and easy to cut, and therefore the multi-cavity vacuumizing packaging bag is provided.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a multi-cavity vacuumizing packaging bag which is provided with an exhaust separation cavity and improves the flatness of the surface of the packaging bag after vacuumizing.

In order to realize the purpose, the utility model provides the following technical scheme:

the utility model provides a but multicavity room evacuation wrapping bag, includes the inside bag body that contains a cavity, bag body top is equipped with first evacuation mouth, the at least one side of bag body is equipped with the superficial layer, evenly open on the superficial layer has a plurality of miniature exhaust holes, be equipped with the exhaust between superficial layer and the bag body and separate the chamber, be equipped with second evacuation mouth between superficial layer inner wall top and the external wall top of bag.

Through adopting above-mentioned scheme, when needs packing, at first put into the bag internal through first evacuation mouth with graininess such as rice, later use evacuation packagine machine through first evacuation mouth and second evacuation mouth, with the air extraction of the internal and exhaust compartment of bag, and accomplish the sealing to first evacuation mouth and second evacuation mouth, accomplish the packing, bag body outer wall surface unevenness this moment, and the superficial layer is because the existence of miniature exhaust hole, make first period back exhaust compartment admit air, the superficial layer becomes loose level from original unevenness, improve the roughness of wrapping bag evacuation back surface, thereby improve pleasing to the eye degree, improve the appeal to the user, external injury destroys the superficial layer at first simultaneously, consequently, certain protective capacities has, reduce the damaged possibility of the bag body.

Preferably, the number of the surface layers is two, and the surface layers are respectively arranged on two sides of the bag body.

Preferably, the bottom and the side edge of the bag body are provided with sealed edges, and the edges of the surface layer are respectively connected with two surfaces of the sealed edges.

Preferably, the outer wall of the surface layer is provided with a printing mark.

Preferably, the surface layer is provided with a handle.

The utility model has the following beneficial effects:

when needing to pack, at first put into the bag internal with graininess thing such as rice through first evacuation mouth, later use evacuation packagine machine through first evacuation mouth and second evacuation mouth, with the air extraction of the internal and exhaust compartment of bag, and accomplish the sealing to first evacuation mouth and second evacuation mouth, accomplish the packing, bag body outer wall surface unevenness this moment, and the superficial layer is because the existence of miniature exhaust hole, make the exhaust compartment admit air after the first period of time, the superficial layer becomes loose and level from original unevenness, improve the roughness of wrapping bag evacuation back surface, thereby improve pleasing to the eye degree, improve the appeal to the user, simultaneously external injury destroys the superficial layer at first, consequently, certain protective capacities has, reduce the damaged possibility of the bag body.

Drawings

FIG. 1 is a schematic cross-sectional view of an embodiment of the present invention;

fig. 2 is a front view of an embodiment of the present invention.

In the figure: 1. a bag body; 2. a surface layer; 3. a micro exhaust hole; 4. an exhaust compartment; 5. a first vacuum port; 6. a second vacuum port; 7. sealing edges; 8. printing a mark; 9. a handle.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

A multi-chamber vacuumizing packaging bag is shown in figures 1-2 and comprises a bag body 1 with a chamber inside, wherein a first vacuumizing port 5 is formed in the top of the bag body 1, a surface layer 2 is arranged on at least one side of the bag body 1, a plurality of micro exhaust holes 3 are uniformly formed in the surface layer 2, an exhaust separation cavity 4 is formed between the surface layer 2 and the bag body 1, and a second vacuumizing port 6 is formed between the top of the inner wall of the surface layer 2 and the top of the outer wall of the bag body 1.

As shown in fig. 1-2, when packaging is required, firstly, granular materials such as rice and the like are put into the bag body 1 through the first vacuumizing port 5, then a vacuumizing packaging machine is used for extracting air in the bag body 1 and the exhaust separation chamber 4 through the first vacuumizing port 5 and the second vacuumizing port 6, sealing (heating sealing and concave-convex strip sealing) of the first vacuumizing port 5 and the second vacuumizing port 6 is completed, and packaging is completed, at the moment, the outer wall surface of the bag body 1 is uneven, the surface layer 2 enables the exhaust separation chamber 4 to intake air after a first period of time due to the existence of the micro exhaust holes 3, the surface layer 2 becomes loose and flat from the original uneven surface, the flatness of the surface of the packaging bag after vacuumizing is improved, the attractiveness of the packaging bag to users is improved, meanwhile, the surface layer 2 is firstly damaged by external injury, and therefore, certain protection capability is achieved, reducing the possibility of breakage of the bag body 1.

As shown in fig. 1, the number of the surface layers 2 is two and the surface layers are respectively arranged at two sides of the bag body 1; the flatness of the two surfaces of the bag body 1 is improved, which is beneficial to improving the overall beauty.
