Description

Exhaust packaging bag

Technical Field

The utility model belongs to the technical field of the wrapping bag technique and specifically relates to an exhaust wrapping bag.

Background

The processing of packaging bags is well established and the prior art has produced a wide variety of packaging bags which are used in a variety of different applications.

The common packaging bag is of a single-layer structure, and is easy to cut in the process of transportation or storage after containing materials, so that in order to increase the protection of the packaging bag, a double-layer packaging bag is adopted, the inner bag is generally used for containing the materials, the outer bag is used for further protecting the inner bag, the outer bag can not only isolate external moisture and dust, but also play a role in resisting wear, however, when the inner bag is filled with the materials, the air in the inner bag and the air filled in the gap between the inner bag and the outer bag can not be discharged, the charging amount of the inner bag can be influenced, and the packaging bag is not favorable for stacking.

Disclosure of Invention

The utility model overcomes prior art's is not enough, provides an exhaust wrapping bag, and it is when feeding, and the interior air escape of wrapping bag of being convenient for.

In order to realize the purpose, the utility model discloses a technical scheme is: the utility model provides an exhaust packaging bag, includes ventilative inner bag and airtight outer bag, be provided with the check valve device on the outer bag, the check valve device includes the mounting panel, the mounting panel inlay establish outside on the bag and with outer bag sealing connection, the mounting panel is provided with the outside carminative check valve of a plurality of, and the inboard of mounting panel is provided with the inner casing that can cover the check valve, is provided with first bleeder vent on the inner casing, and the outside of mounting panel is provided with the outer casing that can cover the check valve, is provided with the second bleeder vent on the inner casing.

By adopting the scheme, the air-permeable inner bag can only be permeable, materials cannot leak out, the one-way valve can only exhaust air to the outside of the packaging bag, external air cannot enter the bag, after the materials are loaded into the inner bag, the air in the inner bag and the air filled in the gap between the inner bag and the outer bag can be manually or automatically discharged from the one-way valve, and the inner guard plate and the outer guard plate can not only supply air to flow through, but also play a role in protecting the one-way valve.

The utility model discloses a further setting is: the check valve is rubber duckbill valve, and rubber duckbill valve includes base and valve body, be provided with the through-hole that supplies the valve body to wear to establish on the mounting panel, the mounting panel is provided with the slot in the inner port department that is close to the through-hole, and the base is inserted and is established slot department.

Through adopting above-mentioned scheme, the one-way conduction of air can be realized to rubber duckbill valve, and the air in the bag can be discharged, and in the unable entering bag of outside air, the shape adaptation of slot and base, rubber duckbill valve simple to operate.

The utility model discloses a further setting is: the inner wall of the inner guard plate is provided with a pressing block, the pressing block corresponds to the rubber duckbill valve, and after the inner guard plate is connected with the mounting plate, the pressing block can press the base at the slot.

Through adopting above-mentioned scheme, the briquetting supports presses the base, can realize the sealed cooperation of rubber duckbill valve, avoids leaking gas, simple structure, reasonable in design.

The utility model discloses a further setting is: the pressing block is provided with a notch for air circulation at the position corresponding to the through hole.

Through adopting above-mentioned scheme, the briquetting can not influence the air escape when pressing rubber duckbill valve, simple structure, reasonable in design.

The utility model discloses a further setting is: the inner guard plate is closely inserted on the mounting plate, and the outer guard plate is closely inserted on the mounting plate.

By adopting the scheme, the structure is simple, and the installation is convenient.

The present invention will be further described with reference to the accompanying drawings.
