Description

Technical Field

[0001] The utility model belongs to the technical field of packaging bags, in particular to a packaging bag with air holes. Background Art

[0002] Packaging bags with air holes can provide better food preservation effects, extend the shelf life of food, and maintain the texture and taste of food. They are an important design and innovation in the field of food packaging.

[0003] According to the disclosed fruit packaging bag with air holes to prevent foreign objects (publication number: CN 104477492 A), it includes a bag body and a self-supporting bottom, the upper end of the bag body has a take-in and put-out port, and the lower end of the bag body is connected to the self-supporting bottom; the self-supporting bottom includes an outer breathable film and several inner breathable films, and the outer breathable film is provided with outer air holes. When storing some foods in life, it is necessary to maintain humidity and air permeability inside the packaging bag to maintain its freshness and breathing, but at the same time, in order to prevent external bacteria and moisture from entering, the packaging bag also needs to have a certain degree of sealing. It is difficult to achieve flexible control of air permeability through the mutual cooperation between the bag body, the outer air holes and other components, and it is difficult to adjust the blockage degree of the air permeable tube, thereby controlling the air permeability of the packaging bag, which needs to be improved. Utility Model Content

[0004] The utility model aims to provide a packaging bag with ventilation holes. Through the mutual cooperation among the ventilation tube, the extrusion rod, the rotating plate and other components inside the ventilation protection component, the rotating plate can be held and rotated, and the rotation of the rotating plate will drive the extrusion rod to rotate. The extrusion rod and the inner wall of the ventilation tube are provided with threads. The extrusion rod will be squeezed into the interior of the ventilation tube along with the threads when it rotates. When ventilation is needed, the rotating plate is rotated a little less, so that the extrusion rod will not completely block the ventilation tube, leaving a partial gap for ventilation. When ventilation is not needed, the rotating plate is rotated a little more, so that the extrusion rod completely enters the interior of the ventilation tube, completely blocks the ventilation tube, so that there is no gap, and the packaging bag cannot be ventilated, thereby sealing the food. Through the structural design of the extrusion rod and the ventilation tube, flexible control of the ventilation can be achieved. By rotating the extrusion rod and the rotating plate, the blocking degree of the ventilation tube can be adjusted, thereby controlling the ventilation amount of the packaging bag, thereby solving the existing problems.

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0006] The utility model discloses a packaging bag with ventilation holes, comprising a packaging bag body, a hook bag fixedly connected to the side of the packaging bag body, a ventilation protection component arranged on the side of the packaging bag body, the ventilation protection component comprising a ventilation tube, one end of the ventilation tube passes through the inner wall of the packaging bag body, an extrusion rod is threadedly connected to the inner wall of the ventilation tube, and one end of the extrusion rod is fixedly connected to a rotating plate.

[0007] Furthermore, a sealing ring is fixedly connected to the side of the rotating plate, the sealing ring is arranged in a circular shape, and the sealing ring is arranged in a rubber material. The design of the sealing ring is conducive to better sealing during sealing.

[0008] Furthermore, a connecting strip is fixedly connected to the top of the packaging bag body, and a moving block is slidably connected to the top of the connecting strip. The design of the connecting strip is conducive to sealing the entrance of the packaging bag to prevent food from falling out.

[0009] Furthermore, two connecting strips are provided and are symmetrical to each other along the vertical center axis of the packaging bag body. The connecting strips are provided in a curved shape and two of them are provided, which is conducive to better sealing.

[0010] Furthermore, a fresh-keeping layer is arranged on the inner wall of the packaging bag body, and a reinforcing layer is arranged below the fresh-keeping layer. The reinforcing layer is located on the inner wall of the packaging bag body, which is beneficial to enhancing the structural strength of the packaging bag.

[0011] Furthermore, the fresh-keeping layer is located between the reinforcing layer and the packaging bag body, and the interior of the fresh-keeping layer includes an oxygen absorber and a humidity regulator. The design of the fresh-keeping layer can protect the food from being spoiled so quickly.

[0012] Furthermore, the reinforcement layer is located between the reinforcement layer and the packaging bag body, and the interior of the reinforcement layer includes glass fiber and polyester fiber. The design of the reinforcement layer can increase its tear resistance and wear resistance, thereby improving the service life of the packaging bag.

[0013] The utility model has the following beneficial effects:

[0014] 1. The utility model realizes the rotation of the rotating plate by holding it, and the rotation of the rotating plate drives the rotation of the extrusion rod. The extrusion rod and the inner wall of the air tube are provided with threads. The extrusion rod will be squeezed into the inside of the air tube as the threads rotate when ventilation is needed. When ventilation is needed, the rotating plate is rotated a little less so that the extrusion rod will not completely block the air tube, leaving a partial gap for ventilation. When ventilation is not needed, the rotating plate is rotated a little more so that the extrusion rod can completely enter the inside of the air tube and completely block the air tube without a gap, so that the packaging bag cannot be ventilated, thereby sealing the food. The structural design of the extrusion rod and the air tube can realize flexible control of the air permeability. The blockage degree of the air tube can be adjusted by rotating the extrusion rod and the rotating plate, thereby controlling the air permeability of the packaging bag.

[0015] 2. The utility model realizes that the fresh-keeping layer, the reinforcing layer and other components inside the breathable protection component cooperate with each other, so that the fresh-keeping layer can protect the food from being damaged so quickly through the internal oxygen absorber and humidity regulator, and the reinforcing layer can increase its tear resistance and wear resistance through the internal glass fiber and polyester fiber, thereby enhancing the structural strength of the packaging bag and improving the service life of the packaging bag.
