Detailed Description

In the following description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like refer to the orientation or position relationship shown in the drawings, and are only for convenience of description and simplification of the description, but do not refer to or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus are not to be construed as limiting the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1 and 2, the low-temperature frozen product sealing bag comprises a bag body, wherein the bag body comprises an inner layer 1, an outer layer 2 and a storage cavity 3, the inner layer 1 and the outer layer 2 are connected with each other, the storage cavity 3 is positioned in the inner layer 1, a squeezing cavity 4 is formed between the inner layer 1 and the outer layer 2, a pressurizing port 5 used for communicating the outside is formed in the outer layer 2, a sealing zipper 6 used for separating the storage cavity 3 from the outside is arranged on the inner layer 1, at least two groups of sealing zippers 6 are arranged, and magnetic materials capable of attracting each other are arranged between the inner layer 1 and the two adjacent groups of sealing zippers 6.

When in use, an article is placed into the storage cavity, cooling liquid is injected into the extrusion cavity 4 along the pressurizing port 5, so that the extrusion cavity 4 is internally expanded, the wall of the inner layer 1 is pushed, the wall of the inner layer 1 is close to the article to extrude the storage cavity 3, the inner layer 1 is attached to the article, air in the storage cavity 3 is extruded out, the storage cavity 3 is sealed through the sealing zipper 6 after the air is extruded out, cooling liquid is continuously injected into the extrusion cavity 4 after the sealing is finished, so that the opening of the storage cavity 3 is tightly pressed by the cooling liquid, then the pressurizing port 5 is sealed, the bag body is placed in the freezing chamber, the cooling liquid in the bag body is rapidly solidified, the stored article is wrapped through the cooling liquid, at the moment, the extrusion cavity 4 at the periphery of the bag body is firstly contacted with the air in the storage cavity 3 during transportation, at the moment, the cooling liquid in the extrusion cavity 4 slowly absorbs heat, and the stored article is in the center of the bag body, if the temperature of the stored object in the center of the bag body needs to be raised, the cooling liquid is firstly raised, the situation that the stored object is damaged due to temperature loss when the stored object is in the center of the bag body can not be directly caused by the cooling liquid, and therefore the purpose of prolonging the keeping time of the refrigeration of the object is achieved. And more than two sets of sealed zip fasteners 6 can make article preserve in storing chamber 3 in the time can not contact with the air, reach the effect that the vacuum was preserved, further slowed down the speed that article rotten, let article can be better preserve. In the same way, the magnetic materials attract each other, so that the sealing zipper 6 is not easy to be separated by external force, and the sealing performance of the sealing zipper 6 is better ensured.

Be provided with sealed lid on the pressure port 5, sealed lid increases the sealed effect of pressure port 5 for pressure port 5 is difficult for flowing out after annotating the coolant liquid, thereby lets the better maintenance of coolant liquid in extrusion chamber 4, reaches better heat preservation effect. Be provided with on outer 2 and be used for strengthening the lid 7 that turns over of storing chamber 3 seals the effect, turn over lid 7 and turn over a book fixedly for turn over lid 7 with the further closure of 3 openings in storing chamber, thereby avoid the opening to receive the extrusion or the striking and open, better keep the not contactless effect of article and outside air. The inner layer 1 is made of elastic materials, the inner layer 1 made of the elastic materials can be better attached to an article by the inner layer 1 in the process of filling and cooling, and the better effect of discharging air out of the storage cavity 3 is achieved. The outer layer 2 is made of polyamide, and the polyamide has the characteristics of no toxicity, light weight, excellent mechanical strength, wear resistance and better corrosion resistance, so that stored objects are more safe when being stored.

It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof.
