On the other hand, set this anti-collision heat preservation array, so that when lock fresh bag is impacted by external force, shockproof heat preservation unit in shockproof heat preservation array 3 can be deformed, absorb and disperse impact force, reduce the force on cold storage array 2, to reduce the risk of lock fresh bag rupture.

[0054] The following will be described in detail with specific embodiments.

[0055] Example 1: see Figure 1 The utility model provides a kind of cloud freeze lock fresh bag, it includes flexible body 1, setting on body 1 cold storage array 2 and setting on body 1 shockproof heat preservation array 3 (i.e. anti-shock structure);Wherein, cold storage array 2 includes the multiple cold storage unit groups of interval setting along the first direction O1 of body 1, i.e. the width direction of body 1, multiple cold storage units 21 in each column of cold storage unit group are communicated by connecting channel 22 along the second direction O2, i.e. the length direction of body 1, and the cold storage unit 21 of first end of each column is provided with injection port (not shown in drawing).Of course, the injection port is provided with easy-to-tear sealing film or sealing plug.

[0056] See Figure 3In the embodiment, the body 1 is made of two layers of film: the first film 100a and the second film 100b by a specific process, such as hot pressing or bonding process, wherein the first film 100a is provided with a plurality of air bubbles (which are filled with air or gas) in a matrix form, thereby forming the shockproof and heat insulation array 3 on the first side 101 of the body 1, and the second film 100b is provided with the cold storage array 2. One of the two layers provided with the cold storage array 2 is used as the inner side for wrapping the article, and the other layer provided with the shockproof and heat insulation array 3 is used as the outer side for shockproof and heat insulation, i.e. the shockproof and heat insulation array 3 and the cold storage array 2 are respectively located on the two sides of the body 1, see Figures 1-3 .

[0057] In other embodiments, the body 1 is made of two layers of film by a specific process and mold, such as hot pressing process, wherein the first film 100a is provided with a plurality of air bubbles (which are filled with air or gas) in a matrix form, thereby forming a plurality of shockproof and heat insulation arrays 3 on the first side 101 of the body 1, and the cold storage array 2 is formed between the two layers of film, and each cold storage unit 21 of the cold storage array 2 is provided with the air bubble on the first side 101, see Figure 4 and Figure 5 . One of the two layers provided with the shockproof and heat insulation array 3 is used as the outer side for shockproof and heat insulation.

[0058] In some embodiments, the cold storage material in the cold storage unit 21 is in liquid state at room temperature, and becomes solid state after freezing, for example, water which becomes ice after freezing. The ice bag with the built-in ice block is suitable for short-distance cold storage transportation, and through the design of a single cold storage unit, the ice bag has a certain foldable or foldable property, thereby better wrapping the article.

[0059] In other embodiments, the cold storage material of the cold storage unit 21 can also use other cold storage materials, for example, low-temperature phase change cold storage material with a phase change temperature of -26℃ to -20℃, which is still in liquid state even in an environment of -18℃. By injecting such cold storage material into the cold storage unit 21 and wrapping the article with it, the contact area of the cold storage unit increases after being squeezed, thereby keeping the temperature in the wrapping at -18℃ or even below for a longer period of time, thereby ensuring the freshness of the article. Moreover, compared with dry ice, it has lower cost and is also suitable for air transportation. In subsequent embodiments, the injection of low-temperature phase change cold storage material into the cold storage array is taken as an example. This is more suitable for longer freezing / preservation or long-distance freezing / preservation, and air transportation. On the one hand, the synergistic effect of the cold storage array and the liquid cold storage material makes the ice bag have higher foldability or foldability, thereby better wrapping, and the contact area between the article is larger, thereby better temperature control, i.e. better low-temperature environment, and achieving ice locking.

[0060] In the present embodiment, the plurality of cold accumulation units 21 in each column of cold accumulation unit groups are arranged along the second direction O2 (perpendicular to the first direction Ol) of the body 1, for example, the length direction of the body, and the plurality of cold accumulation units 21 in adjacent two columns of cold accumulation unit groups are staggered arranged along the second direction O2 of the body 1. That is, only each column of the cold accumulation array 2 is parallel to each other. For example, see Figure 1 If the width direction of the body 1 is the first direction Ol and the length direction is the second direction O2, the cold accumulation array 2 includes a plurality of columns of cold accumulation unit groups which are parallel and arranged at intervals along the width direction of the body 1, and each group of cold accumulation units includes a plurality of cold accumulation units 21 which are uniformly arranged at intervals along the length direction of the body 1, and adjacent two cold accumulation units 21 are communicated by the first communication channel 22. Moreover, the cold accumulation units 21 in adjacent two columns of cold accumulation unit groups are staggered arranged, that is, the gap between adjacent two cold accumulation units 21 in the previous column corresponds to one cold accumulation unit in the next column. In this way, the staggered arrangement makes the arrangement between columns more compact, so that the contact area between the cold accumulation array 2 and the object to be wrapped is larger. Of course, due to the compact arrangement, the foldability is lost to some extent, therefore, in order to make up for or eliminate this loss, the size of the cold accumulation unit 21 can be further reduced.

[0061] Of course, in other embodiments, if the length direction of the body 1 is the first direction Ol and the width direction is the second direction O2, the cold accumulation array 2 includes a plurality of columns of cold accumulation unit groups which are parallel and arranged at intervals along the length direction of the body 1, and each group of cold accumulation units includes a plurality of cold accumulation units 21 which are uniformly arranged at intervals along the width direction of the body 1, and adjacent two cold accumulation units 21 are communicated by the communication channel 22.

[0062] In other embodiments, instead of the above-mentioned staggered arrangement, the connecting lines between the corresponding rows of cold accumulation units in all columns of cold accumulation unit groups are parallel to the first direction Ol of the body 1, that is, each row of the cold accumulation array 2 is parallel to each other, and each column is parallel to each other, forming a regular matrix. For example, see Figure 5 If the length direction of the body 1 is the first direction Ol and the width direction is the second direction O2, the cold accumulation array 2 includes a plurality of columns of cold accumulation unit groups which are parallel and arranged at intervals along the length direction of the body 1, and each group of cold accumulation units includes a plurality of cold accumulation units 21 which are uniformly arranged at intervals along the width direction of the body 1, and adjacent two cold accumulation units 21 are communicated by the first communication channel 22. Moreover, the connecting lines between the corresponding rows of cold accumulation units 21 in all columns are parallel to the length direction of the body 1, that is, each row of the cold accumulation array 2 is parallel to each other, and each column is parallel to each other, forming a regular matrix. Compared with the above-mentioned staggered arrangement, the matrix arrangement makes the spacing between columns slightly wider, and when the cold accumulation units 21 are filled with low-temperature phase change cold accumulation material, the body 1 has better foldability and pliability, so that it can better wrap the object.

[0063] Further, in some embodiments, each of the first or last end of the cold storage unit 21 is connected with a buffer unit 23 through a second connecting channel 24, and the injection port is arranged on the buffer unit 23, see Figure 3 .

[0064] If the cold storage material in the cold storage unit 21 is the low-temperature phase change cold storage material as described above, generally, there is no or only a small amount of liquid cold storage material in the buffer unit 23, and when the bag is pressed, for example, by the gravity of the food or by other bags, part of the cold storage material in the cold storage unit 21 will enter the buffer unit 23 through the connecting channel 22, thereby reducing the risk of the cold storage unit 21 being broken to a certain extent.

[0065] Preferably, the volume of the buffer unit 23 is smaller than the volume of the cold storage unit 21; the volume of the cold storage unit 21 is greater than the volume of the shockproof and heat insulation unit 31 in the shockproof and heat insulation array 3. For example, the volume of the cold storage unit 21 is at least 3 times or more than the volume of the shockproof and heat insulation unit 31.

[0066] In some embodiments, the size of the second connecting channel 24 is smaller than the first connecting channel 22, for example, the diameter of the second connecting channel 24 is smaller than the diameter of the first connecting channel 22, so that under normal circumstances, almost no cold storage material will flow from the cold storage unit into the buffer unit, and only under certain pressure will the cold storage material enter the buffer unit. Further, the length of the second connecting channel 24 is greater than the length of the first connecting channel 22.

[0067] In some embodiments, when the cold storage liquid is injected into the cold storage unit 21, the cold storage unit 21 is in the shape of an ellipsoid. For example, when the cold storage liquid is injected into the cold storage unit 21, the cross section of the cold storage unit 21 is in the shape of an ellipse or approximately in the shape of an ellipse. Of course, the cold storage unit 21 can also have other shapes, for example, after the cold storage liquid is injected, the cold storage unit 21 is in the shape of a regular geometric body such as a cube or a sphere, and of course, the cold storage unit 21 can also be in other irregular shapes, or a combination of the two (i.e., a combination of regular geometric bodies and irregular shapes).

[0068] Compared with the bamboo slip type ice bag, in the present embodiment, by arranging the cold storage unit array 2, the body 1 has higher foldability, wrapping and fit, and when the cold storage unit 21 filled with cold storage material and frozen after being used to wrap the food, the contact area between the cold storage unit 21 and the food is larger, thereby better preserving the food.

[0069] In some embodiments, when the cold storage liquid is injected into the cold storage unit 21, the cold storage unit 21 is in the shape of a cylinder, see Figure 11 .

[0070] In some embodiments, the body 1, for example, the first film 100a and the second film 100b, is made of biodegradable material. Preferably, the biodegradable material includes straw or modified straw. In other embodiments, the first film 100a can also be made of plastic film made of composite plant fiber powder, so as to reduce the possible cold energy loss and improve the heat preservation effect; and the second film 100b is made of ordinary food-grade plastic film.

[0071] In some embodiments, the body 1 is also provided with an NFC chip, so that the user can write product information in the NFC chip, so that the consumer receiving the product can also obtain the product information from the NFC, such as product batch, transportation track, temperature control curve, etc. Full-link data, to provide "transparent cold chain" trust endorsement for high-end customers.

[0072] Herein, "cloud freezing" refers to that the body loaded with cold storage material can provide a long-time fresh-keeping environment (i.e. can keep the temperature at or close to a stable value, for example, minus 18℃) after freezing, so that the fresh-keeping goods can maintain their freshness for a long time, i.e. to achieve fresh-keeping.

[0073] In some embodiments, both the foldability of the fresh-keeping bag and the contact area between the cold storage material and the goods should be ensured, therefore, the spacing between the two adjacent groups of cold storage units should not be too large or too small. If it is too large, the foldability is good, but the contact area is small, which affects the fresh-keeping effect; if it is too small, the foldability is not good enough, so that the goods cannot be well wrapped, and the cold storage material cannot be well contacted with the goods. In the present embodiment, the spacing between the two adjacent groups of cold storage units is in the range of 80mm-85mm, and preferably 80mm; the spacing between the two adjacent cold storage units 21 in each group of cold storage units is in the range of 55mm-70mm, and preferably 60mm.

[0074] Embodiment 2: The utility model also provides another fresh-keeping bag, which comprises the components in embodiment 1, and the difference is that, in the present embodiment, in order to facilitate filling of the cold storage material, the injection port is not arranged on the cold storage unit 21 at the head or tail of each cold storage array, but the third connecting channel 25 is used to connect the two cold storage units 21 at the head or tail of the two adjacent cold storage arrays.

[0075] Referring to Figure 6bThe two cold storage units 21 at the tail ends of the first column and the second column are communicated through the third connecting channel 25 from left to right, and the two cold storage units 21 at the head ends of the second column and the third column are communicated through the third connecting channel 25, and the same is true for the subsequent columns. In this way, on the one hand, it is more convenient to fill the cold storage material, and on the other hand, when the cold storage unit is subjected to pressure, for example, the gravity of the wrapped object, etc., the cold storage units in the array are connected, so that the force can be dispersed to all the cold storage units, thereby avoiding the problem of stress concentration on a certain cold storage unit or a certain area and the problem of rupture, and further improving the service life of the preservation bag to a certain extent.

[0076] Embodiment 3: The utility model also provides another fresh-keeping bag, which comprises the components in the above embodiment 1, and differs from the above embodiment 1 in that, referring to Figures 6a to 6c , the inner side of the body 1, for example, the second side 102, is provided with a first support column array, and the first support column array comprises: a plurality of support column groups arranged at intervals along the first direction O1 of the body 1, and each support column group comprises a plurality of support columns 4 arranged at intervals along the second direction O2.

[0077] Specifically, referring to Figure 6d , the support column 4 comprises: a support body 41 fixed to the inner side of the body 1 at a first end, and a clamping groove 43 arranged at a second end of the support body 41 away from the inner side; when the body 1 is bent, the clamping groove 43 on the support column 4 can be buckled with the clamping groove 43 on another support column 4, referring to Figures 8a to 8c .

[0078] Referring to Figure 6d , in some embodiments, three clamping blocks 42 are arranged on the second end of the support body 41, and the three clamping blocks 42 and the second end of the support body 41 enclose the clamping groove 43 with an open top and one side. Preferably, the three clamping blocks 42 are arranged in a triangular shape. Further, a protrusion 44 is arranged on one side of the clamping groove 43 corresponding to one clamping block 42 at the top of the triangular structure, so that when two support columns 4 are buckled together, the two protrusions 44 buckle and stabilize. Preferably, the cross section of the protrusion is triangular, and the surface in contact between the two protrusions 44 is an inclined surface, that is, the surface has a certain inclination angle, thereby playing a guiding role and a buckling role.

[0079] Of course, in other embodiments, a plurality of support column groups can also be arranged at intervals along the second direction O2 of the body 1, and each support column group comprises a plurality of support columns 4 arranged at intervals along the first direction O1.

[0080] Embodiment 4: The utility model also provides another fresh-keeping bag, which comprises the components in the above embodiment 1 or 2 or 3, and differs from the above embodiment 1 or 2 or 3 in that, the outer side of the body 1, for example, the first side 101, is provided with a second support column array.

[0081] In the embodiment, the second support column array comprises: a plurality of columns of support column groups arranged at intervals along the first direction O1 of the body 1, each support column 4 in the support column group comprises: a support body 41 fixed to the outer side at a first end, and a clamping groove 43 arranged at a second end of the support body 41 away from the outer side; when a plurality of cloud lock fresh bags are stacked, the clamping groove 43 on at least one support column 4 on the lower cloud lock fresh bag can be buckled with the clamping groove 43 on at least one support column 4 on the upper cloud lock fresh bag.

[0082] In some embodiments, three clamping blocks 42 are arranged on the second end of the support body 41, and the three clamping blocks 42 and the second end of the support body 41 enclose the clamping groove 43 having a top opening and a side opening. Preferably, the three clamping blocks 42 are arranged in a triangular shape.

[0083] Preferably, when the second support column array and the first support column array are arranged at the same time, each support column 41 on the outer side corresponds to each support column 41 on the inner side, so as to realize the dispersion and support of pressure and prevent excessive extrusion deformation of the articles wrapped on the inner side.

[0084] Embodiment 5: The utility model also provides another kind of fresh-keeping bag, it includes each component in the above-mentioned embodiment 1 or 2 or 3 or 4, different is that in the embodiment, the body 1 also includes the packaging structure 5 around the shockproof heat preservation array 3 or cold storage array 2.

[0085] Since the body 1 has a certain length, and the articles are usually placed in the middle of the body 1 during use, and then the articles are placed on the articles in turn on both sides of the body 1 to form a package, but during transportation, the two sides are easy to loosen, and there is no sealing from front to back, so during transportation (especially after receiving a collision), part of the articles may be exposed from the front and back openings, affecting the fresh-keeping effect. Therefore, in the embodiment, the packaging structure 5 is arranged, so that when the articles are wrapped, a sealed space (or almost sealed space) can be formed, as shown in Figures 7 to 8b .

[0086] Specifically, in some embodiments, the packaging structure 5 can adopt an adhesive around the shockproof heat preservation array 3 or cold storage array 2 (for example, close to the edge of the body 1). Preferably, the adhesive is provided with a tear-resistant film for protection, which can be torn when needed, so that when the articles are wrapped in the body 1, the adhesive on the edge can seal the front and back openings after the articles are wrapped, and the two sides of the upper and lower layers of the body can also be adhered by the adhesive, thereby forming a seal. Specifically, there is a 5cm gap between the shockproof heat preservation array 3 or cold storage array 2 and the edge of the body 1, so a circle of adhesive or other packaging structure can be arranged along the edge of the body 1.

[0087] Referring to Figure 9 In some other embodiments, the packaging structure 5 comprises a plurality of buckling members 51 evenly arranged on the first long edge of the body 1, and a slit 52 is arranged between two adjacent buckling members 51. Similarly, a plurality of buckling members 51 are evenly arranged on the second long edge of the body 1, and a slit 52 is arranged between two adjacent buckling members 51. The buckling member 51 comprises a movable leaf 512 connected to the body 1, and a clamping strip 511 is connected to the free end of the movable leaf 512 and can pass through the slit 52 and be buckled with the slit 52. Preferably, the length of the clamping strip 511 is greater than the length of the slit 52.

[0088] When the body 1 is used to wrap an article, the buckling members 51 on the first long edge can be locked by penetrating the slits 52 on the first long edge, thereby achieving the closure of the front end opening of the body. Similarly, the buckling members 51 on the second long edge can be locked by penetrating the slits 52 on the second long edge, thereby achieving the closure of the rear end opening of the body, so that the body forms an almost sealed bag and the article is wrapped inside the bag.

[0089] Preferably, the movable leaf 512 is made of flexible material, which can also be made of the same material as the body 1. The clamping strip is made of slightly hard material, such as plastic or rubber, and has a certain adsorption or friction force with the surface of the body.

[0090] In some other embodiments, for some small volume articles that require better sealing, the packaging structure 5 can be used to combine the sheet-shaped body 1 into an open bag. Referring to Figure 10 The body 1 comprises a first sheet area la, a second sheet area lb and a third sheet area lc arranged in sequence along the length direction of the body 1. The packaging structure 5 is a zipper assembly arranged on the edge area of the body 1 without the cold storage array 2 and the shockproof and heat preservation array 3. Preferably, the lengths of the first sheet area la and the second sheet area lb are the same and greater than the length of the third sheet area lc.

[0091] For example, the upper and lower sides of the wrapping surface of the first sheet area la are respectively provided with first zippers 53, and the upper and lower sides of the wrapping surface of the second sheet area lc are respectively provided with second zippers 54. When the first sheet area la and the second sheet area lb are folded, the teeth of the first zippers 53 and the second zippers 54 can be matched, such as Figure 10The first and second areas 1a and 1b are connected by a third area 1c, and the third area 1c is provided with a plurality of shockproof and heat insulation arrays 3. The shockproof and heat insulation arrays 3 are arranged on the side of the third area 1c away from the second area 1b, so that a wrapping space can be formed between the first and second areas 1a and 1b. Correspondingly, in order to better seal, a press buckle or a first zipper is arranged on the side of the wrapping surface of the third area 1c away from the second area 1b, and of course, a buckle slot matched with the press buckle or a second zipper matched with the first zipper is arranged on the other side of the first area 1a (i.e. the side provided with the shockproof and heat insulation arrays 3).

[0092] Of course, in other embodiments, the zipper assemblies on the three areas can also be press and go buckles.

[0093] Of course, in other embodiments, a pull rope can also be arranged directly on the body 1, so that after the pull rope is pulled, the body forms a bag with only one opening, and the pull rope is arranged around the opening to seal the opening. For example, a pull rope is embedded in the four edges of the wrapping surface of the body 1, and the two ends of the pull rope are pulled out. When the two ends of the pull rope are pulled to gather the four edges, the body 1 forms a wrapping space.
