Description

Packaging bag dry food packaging fresh-keeping device

The invention relates to a fresh-keeping package for dry food packaging bags, which can avoid food contamination or accidental eating accidents caused by fresh-keeping agents, and can effectively improve the safety of fresh-keeping packaging.

Press, dry foods such as tea, coffee, biscuits or snacks are packaged in packaging bags. It is common to put preservatives, such as desiccants or deoxidizers, together in the food in the packaging bags, thereby reducing or reducing or Avoid moisture, oxidation or deterioration of food; generally speaking, the desiccant/deoxidizer is put into the food packaging bag in the form of a small package of breathable paper. If the outside of the food packaging bag is squeezed by improper external force, the desiccant package /The deoxidizer package may be damaged or ruptured, and it is difficult to completely prevent the food from being contaminated. Even the accidental accident of eating due to temporary negligence or recognition by children does not affect the safety of food preservation packaging for a long time.

The main object of the present invention is to provide a fresh-keeping device for dry food packaging of a packaging bag, which is a fresh-keeping device, which includes a storage box formed of an extrusion-resistant material, a sealing film, a breathable film and a sealing film; A storage chamber is formed inside the body of the box, the storage chamber is filled with food preservatives, and a fitting portion is formed on the periphery of the inlet end, and at the bottom end, more than one ventilation hole is opened, and the outlet of the ventilation hole A class groove is provided at the end; the sealing film is attached to the fitting part of the storage box, and the preservative is packaged and stored in the box body Indoor, and the outer surface end is used as a fitting surface; the breathable film is attached to the class groove at the bottom of the box body of the storage box to restrict the preservative in the storage room from leaking out of the vent hole; The sealing film is attached to the bottom of the box body of the storage box, and the outer surface of the class slot seals the storage chamber from the external air, and the class slot maintains a gap with the breathable film The gap is also conducive to piercing the sealing film to open the vent hole, which can prevent the needle piercing action from hurting the breathable film and ensure that the breathable film effectively controls the preservatives; when the dry food wants to use packaging bags for fresh-keeping packaging At the time, during the production of the packaging bag, it is only necessary to pierce the sealing film to form more than one vent hole at the bottom of the storage box of the fresh food container for a short period of time, and attach the bonding surface of the fresh food container to the On the predetermined internal paper surface, after the packaging bag completes the packaging of the dried food, the box body of the storage box, the storage freshener in the storage room passes through the air-permeable film from the air-permeable hole, and then from the air hole and the packaging bag on the sealing film The internal communication of the bag body can achieve the preservation effect of the preservative in the storage box on the dried food; the overall structure is protected by external force by the preservative stored in the box body of the storage box, and the packaging bag When opening and using dry food, the fresh-keeping device is fixed on the paper surface inside the packaging bag and cannot be taken out, so that the dry food packaging bag fresh-keeping packaging can effectively avoid the contamination of the food with fresh-keeping agents or accidental eating accidents, and improve the safety of the dry food fresh-keeping packaging Sex.

The second object of the present invention is to provide a dry food packaging fresh-keeping device for packaging bags, wherein the breathable film is attached to the class groove at the bottom of the box body of the storage box and maintains a gap with the sealing film, When the sealing film piercing hole is formed with a vent hole, the fresh-keeping agent in the storage room can be controlled by the breathable film from leaking or leaking from the vent hole, and the gap is conducive to piercing the sealing film to open the vent The stomata action can prevent the needle puncture action from hurting the breathable film and ensure that the breathable film effectively controls the preservative.

Still another object of the present invention is to provide a dry food packaging fresh-keeping device for packaging bags, wherein the breathable film is attached to the inner surface of the bottom from the box body storage chamber of the storage box, so as to be the bottom of the storage box A vent hole is formed in the puncture hole of the sealing film at the position of the class slot, so that when the fresh-keeping agent in the storage room has a fresh-keeping effect on the dried food in the packaging bag, the fresh-keeping agent in the storage room can be restricted by the breathable film in the storage room to ensure the fresh-keeping agent No leakage or leakage from the vent.
