[0081] In order to make the technical solutions and advantages in the embodiments of the present application more clearly understood, the exemplary embodiments of the present application are further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than an exhaustive list of all the embodiments. It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0082] Figure 1 A schematic structural diagram of a flexible package 100 provided in an embodiment of the present disclosure is shown. The flexible package 100 encloses a cavity 100a, which can be used to accommodate objects that need to be kept warm. A folding portion 100b is provided on the flexible package 100, which can be easily folded. When the flexible package 100 is squeezed, the flexible package 100 is bent and deformed on both sides of the folding portion to change the shape, reduce the volume, and facilitate storage. In the embodiment of the present application, by providing the folding portion 100b on the flexible package 100, it can have the function of assisting folding, assisting the user to quickly fold the package to a set shape, improving the folding efficiency, and avoiding the formation of folds at undesirable positions on the flexible package 100, having the function of protecting the flexible package 100, so that the appearance of the flexible package 100 remains neat and beautiful for a long time, and the durability of the flexible package 100 is improved.

[0083] like Figures 1 to 15 As shown, a plurality of folding portions 100 b may be provided on the flexible package 100 to achieve folding of a plurality of portions of the flexible package 100 and minimize the storage volume of the flexible package 100 .

[0084] Figure 31 shows a cross-sectional view of a flexible package provided by an embodiment of the present disclosure. The flexible package 100 is provided with an inner fabric 14, a filling layer 15 and an outer fabric 16 in sequence from the inside to the outside. The filling layer 15 is located between the inner fabric 14 and the outer fabric 16. The folding portion 100b of the flexible package 100 of the present application is not formed by multiple foldings, but is specifically designed to form a permanent, effective and beautiful folding portion 100b.

[0085] In some possible implementations, such as Figures 1 to 15 As shown, the folding portion 100b includes a plurality of grooves a arranged along a set trajectory line on the flexible package 100, wherein an opening 155 is arranged on the filling layer 15, the inner fabric 14 and the outer fabric 16 are connected at the opening 155, and the outer fabric 16 and the inner fabric 14 both extend into the opening 155 and are in contact with each other, so that the surfaces of the inner fabric 14 and the outer fabric 16 are sunken to form the groove a. The portion of the inner filling layer 15 corresponding to the groove a portion has no solid structure but a hole, which naturally makes the structural rigidity of the folding portion low. When the flexible package 100 is subjected to external force, it will bend and deform preferentially at the folding portion 100b. The flexible package 100 has a folded state and an unfolded state. In the folded state, the flexible package 100 is bent and deformed at least on both sides of a portion of the folding portion 100b. In the unfolded state, the surface of the package structure on both sides of the folding portion 100b can be smoothly transitioned.

[0086] In some possible implementations, the outer fabric 16 and the inner fabric 14 are connected and fixed by hot-melt at the opening, and when the outer fabric 16 and the inner fabric 14 are in contact, they are heated so that the outer fabric 16 and the inner fabric 14 are directly bonded and fixed. The hot-melt connection between the outer fabric 16 and the inner fabric 14 has the advantages of strong bonding force, fast bonding speed and high bonding strength.

[0087] In some possible implementations, the outer fabric 16 and the inner fabric 14 can be connected and fixed at the opening 155 by means of colloid bonding. Liquid or semi-solid glue can be applied to the facing sides of the inner fabric 14 and the outer fabric 16, and then the two are directly attached at the opening 155, and the two are bonded and fixed after the glue dries.

[0088] In some possible implementations, such as Figure 1 As shown, the flexible package 100 includes a plurality of side sheets 1, each of which encloses a cavity 100a, and at least a portion of a folding portion 100b is provided on each side sheet 1. The folding portions are provided on each side sheet 1 of the flexible package 100 so that all side sheets 1 of the flexible package 100 can be folded and deformed synchronously, avoiding the formation of folds in the non-folding area during the folding process, thereby improving the folding efficiency.

[0089] In some possible implementations, the groove a is a long groove. When the flexible package is in an unfolded state and supported on a horizontal support surface, the groove a is parallel to the horizontal support surface 400, or the groove a is perpendicular to the horizontal support surface 400, or the groove a and the horizontal support surface 400 have an angle, which is an acute angle or an obtuse angle. Each groove a has the above three settings.

[0090] The long grooves extend along the set trajectory line. The long grooves make a relatively long area of ​​the flexible enclosure 100 have low structural rigidity, so that the area is easy to deform and can be bent and deformed smoothly during the folding process of the flexible enclosure.

[0091] like Fig.24 and Fig.25 The flexible bag shown in the figure includes four side pieces 1 and a bottom piece connecting the four side pieces 1. The four side pieces 1 are enclosed to form a top opening. The middle positions of two opposite side pieces 1 among the four side pieces 1 are provided with folded parts 100b extending in the longitudinal direction. When the flexible bag 100 is supported on the horizontal support surface 400, the folded parts extending in the longitudinal direction include a plurality of grooves a arranged in sequence, each groove a is perpendicular to the horizontal support surface 400. At the bottom of the folded parts extending in the longitudinal direction, there are two inclined folded parts extending to the two side corners of the bottom of the side piece 1, respectively, and the inclined folded parts include a plurality of inclined extending grooves a. The flexible bag also includes an inner layer fabric, a filling layer and an outer layer fabric, and an air nozzle 1b is provided on the flexible bag 100. Consumers can squeeze the flexible bag 100 to both sides along the thickness direction of the flexible bag 100, so that the flexible bag is deformed and bent at each folded part, and finally folded into a flat structure, which is convenient for storage.

[0092] In some possible implementations, a sealed cavity 1a is formed between the inner fabric 14 and the outer fabric 16. An air nozzle 1b connected to the sealed cavity 1a is provided on the inner fabric 14 or the outer fabric 16. The air nozzle 1b can be used to inflate the flexible package 100, and the inner non-perforated filling layer 15 will expand and bulge. The outer fabric 16 and the inner fabric 14 of the perforated part of the filling layer 15 are connected together by hot melting to form a transverse closed groove a. The inflated and bulged filling layer 15 will ensure that the entire flexible package 100 is upright after inflation. Figure 1 and Figure 2 As shown, the transverse long groove a on the flexible package 100 allows the flexible package 100 to be pressed downward and folded. When the flexible package 100 is folded, the package is squeezed, and the gas between the inner layer fabric 14 and the outer layer fabric 16 is discharged through the air nozzle 1b, which facilitates folding. The groove a is isolated from the sealed cavity 1a, and the gas in the sealed cavity 1a will not leak from the groove a.

[0093] It should be noted that see Figures 1 to 15As shown, each groove a on the flexible package 100 may include any one or more of a transverse groove, an oblique groove and a longitudinal groove. The directions defined in the present application, such as the transverse direction, the oblique direction and the longitudinal direction, should be determined according to the state in which the flexible package 100 is unfolded and supported on the horizontal support surface 400. The transverse direction may be a direction substantially parallel to the horizontal plane, the oblique direction may be a direction having an angle of non-90° with the horizontal direction, and the longitudinal direction may be a direction perpendicular to the horizontal plane.

[0094] In some possible implementations, see Figure 1 , Figure 2 and Fig. 27 As shown, the folded portion includes a first folded portion 2, and the first folded portion 2 extends along the circumference of the flexible package 100. Figure 1 , Figure 2 In the implementation mode, the user can directly press the flexible package 100 from top to bottom to exhaust air through the air nozzle 1b, and at the same time, the flexible package 100 can be bent and deformed at the first fold portion 2 around the package, thereby reducing the height of the flexible package 100. The cross-sectional diameter of the package side wall can be consistent from the bottom to the top opening side, or it can be inconsistent. For example, the flexible package 100 can have a large opening at the top, a small middle part, and a large bottom. The flexible package 100 can also have a small middle part, a large bottom, and a small mouth. The flexible package 100 can also have a large middle part, a small bottom, and a large opening. The flexible package 100 can be designed in different shapes, and the present application does not limit the specific shape of the flexible package 100. For Fig. 27 In the embodiment, the flexible package 100 is relatively flat, and the user can directly fold the upper and lower ends of the flexible package 100 along the first crease portion 2 with the first crease portion 2 as the folding line, and the air nozzle 1b provides exhaust.

[0095] In some possible embodiments, the first folding portion 2 includes a plurality of grooves a arranged in sequence and spaced apart, and the connecting line of each groove a forms a circular closed folding line. The length of the groove a can be greater than the distance between adjacent grooves a, so that the rigidity of the folding line is low and the whole folding line is easily bent and deformed when subjected to force. Each groove a can be a transverse groove, such as Figure 1 and Fig. 9 Each groove a may also be a slightly inclined groove, such as Figure 7 and Figure 8 shown.

[0096] In some possible implementations, see Figure 1 As shown, when the flexible package 100 is in the unfolded state, each first groove a is located in the same plane. Each groove a is located in the same plane, and each groove a divides the package into two regular upper and lower structures. The upper structure can be retracted into the inner side of the lower structure as a whole, or sleeved on the outer side of the lower structure. The flexible package 100 forms an inner and outer nesting folding effect.

[0097] In some possible implementations, such as Figures 4 to 9 As shown, the folding portion may include a plurality of second folding portions 3, and the second folding portions 3 extend obliquely. When the flexible package is in an unfolded state and supported on a horizontal support surface, the second folding portion and the horizontal support surface have an angle. The second folding portion 3 and the first folding portion 2 have an angle. The second folding portion 3 intersects with the first folding portion 2, increasing the folding portion of the flexible package 100. The flexible package 100 can be folded inwardly at the first folding portion 2 and folded outwardly at the second folding portion 3, so that the flexible package 100 has a folding effect in which the upper and lower parts of the structure are attached to each other, so that the flexible package 100 can be folded flatter and smaller in size.

[0098] In some possible implementations, such as Figures 4 to 9 As shown, at least two opposite side pieces 1 of the flexible package 100 are provided with two intersecting second folding portions 3, and the four ends of the two intersecting second folding portions 3 are respectively away from each other, and extend to the upper sides and the lower sides, such as extending to the top sides and the bottom sides of the side piece 1. The first folding portion in the middle of the side piece 1 can be folded inward laterally, and the two intersecting second folding portions 3 can be folded outward to form edges. The intersecting second folding portions 3 are located in the same straight line in the folded state, so that the flexible package 100 is folded flatter, which is convenient for storage. It should be noted that the "above" and "below" mentioned in this application should be understood as the upper and lower parts of the flexible package when the flexible package is supported on a horizontal support surface.

[0099] like Figure 20 to Figure 23 The flexible package 100 shown includes a cover sheet, a bottom sheet and four side sheets 1. The four side sheets 1 enclose a cavity 100a, a top opening and a bottom opening. The bottom sheet connects the side sheets 1 to close the bottom opening. The cover sheet can be connected to the side sheets 1 to close or open the top opening. A first folding portion 2 is provided on the flexible package. All strip-shaped grooves a of the first folding portion 2 are sequentially arranged along the circumference of the flexible package 100. Two intersecting second folding portions 3 are respectively provided on the two opposite side sheets 1 of the flexible package. The four ends of the two intersecting second folding portions 3 are respectively away from each other and extend to the upper sides and the lower sides, for example, to the top sides and the bottom sides of the side sheets 1. The flexible package 100 also includes an inner layer of fabric, a filling layer and an outer layer of fabric, and an air nozzle 1b is provided on the flexible package 100. Consumers can directly press the flexible bag 100 from top to bottom, so that the gas between the inner fabric and the outer fabric is discharged from the air nozzle 1b. At this time, the flexible bag 100 will be folded in a circle at the first crease portion 2, and the two opposite side pieces will be bent at the intersecting second crease portion 3. Finally, the entire flexible bag 100 is folded into a flat structure, which is convenient for storage.

[0100] For example, see Fig.23 The flexible package 100 shown includes a cover sheet, a bottom sheet and four side sheets 1, the four side sheets 1 enclose a cavity, a top opening and a bottom opening, the bottom sheet connects the side sheets 1 to close the bottom opening, and the cover sheet can be connected to the side sheets 1 to close or open the top opening. A first folding part is provided in the middle of two opposite side sheets 1, and the first folding part is only provided on two opposite side sheets 1. Two intersecting second folding parts 3 are provided on the other two opposite side sheets 1 of the flexible package 100, and the four ends of the two intersecting second folding parts 3 are respectively away from each other, and extend to the upper sides and the lower sides respectively, for example, to the top sides and the bottom sides of the side sheets 1. The flexible package 100 also includes an inner layer of fabric, a filling layer and an outer layer of fabric, and an air nozzle is provided on the flexible package. Consumers can directly press the flexible bag 100 from top to bottom so that the gas between the inner fabric and the outer fabric is discharged from the air nozzle. At this time, the flexible bag 100 will be folded inward at the first crease portion 2 on the two side pieces 1, and at the same time, it will be folded inward at the second crease portion 3 on the other two side pieces 1. The entire flexible bag 100 will eventually fold into a flat structure, which is convenient for storage.

[0101] In some possible implementations, such as Figures 4 to 6 As shown, the flexible package 100 includes two first side pieces 11, a second side piece 12 and a third side piece 13, the second side piece 12 and the third side piece 13 are respectively arranged on both sides of the first side piece 11, and the second side piece 12 and the third side piece 13 are respectively connected to the two first side pieces 11, and two intersecting second folding parts 3 are arranged on the two first side pieces 11, one end of one second folding part 3 extends to the top midpoint or the top point of the second side piece 12, and the other end extends to the bottom midpoint or the bottom end point of the third side piece 13; one end of the other second folding part 3 extends to the top midpoint or the top point of the third side piece 13, and the other end extends to the bottom midpoint or the bottom end point of the second side piece 12.

[0102] The folded portion extends to the second side piece 12 and the third side piece 13 of the flexible package 100, so that all the side pieces 1 of the flexible package 100 are folded synchronously, and the bending parts are all the folded portions set on the flexible package 100, and no folds are formed in other parts, which reduces the folding resistance, reduces the folding difficulty, and improves the folding efficiency.

[0103] In some possible implementations, see Figures 12 to 15As shown, the folding portion includes a plurality of third folds 4, each of which is arranged in sequence along the circumference of the flexible package 100, and each of which has an angle with the first folding portion 2. The flexible package 100 can be rotated and folded along the inclined direction of each third fold to reduce the height. It should be noted that the flexible package provided in the embodiment of the present application can only be provided with the third folding portion 4, and the first folding portion 2 is not provided.

[0104] Each third fold 4 may also include a plurality of inclined long strip grooves a, and each groove a is arranged in sequence at intervals. When the flexible package 100 is in the unfolded state, each groove a of the same third fold 4 may be located on the same straight line. When the flexible package 100 is rotated, the flexible package 100 will bend and deform synchronously at each fold portion. Finally, the top surface of the package and the bottom surface of the package are gradually approached until the distance is less than the set value.

[0105] In some possible embodiments, the flexible package 100 includes a plurality of side panels 1, and each side panel 1 is provided with at least one third fold 4. Figures 12 to 15 As shown, the flexible package 100 may have four side sheets 1, and adjacent side sheets 1 are perpendicular to each other. The flexible package 100 is roughly a cube. A third fold 4 is respectively provided on each side sheet 1, and the two ends of the third fold 4 extend to the two ends of the diagonal line of the side sheet 1. The side sheets 1 can be folded and deformed by rotating the flexible package 100 in the forward direction, and the height of the flexible package 100 can be reduced. The top cover of the flexible package 100 can be rotated in the reverse direction to restore the side sheets 1 to their original state and gradually unfold.

[0106] In some possible implementations, the third fold 4 is disposed on one side or both sides of the first fold portion 2 along the height direction.

[0107] The flexible package 100 is provided with a first folding portion 2 and a second folding portion 3, respectively, so that part of the structure of the flexible package 100 can be folded up and down, and part of the structure can be rotated and folded, further reducing the folded volume of the flexible package 100. In the process of folding the flexible package 100, part of the structure of the flexible package 100 can be rotated and folded first, and then the flexible package 100 can be pressed down, so that the flexible package can be folded into a gasket shape, which is convenient for storage.

[0108] In some possible implementations, the third fold 4 and the first fold portion 2 are alternately arranged in sequence along the height direction of the flexible package 100. When the height of the flexible package 100 is relatively high, multiple first fold portions 2 and multiple groups of third folds 4 may be arranged on the flexible package 100, and the first fold portion 2 and the third fold 4 are alternately arranged in sequence along the height direction, so that the higher flexible package 100 can be folded to a smaller height. When folding the flexible package 100, the partial structure of the flexible package 100 may be rotated and folded first, and then the flexible package 100 may be pressed down, so that the partial structures after the rotation and folding are close to each other up and down, and finally the partial structures are nested inside and outside, so that the higher package forms a flat folded state, and the height dimension of the flexible package 100 is minimized to the maximum extent.

[0109] In some possible implementations, see Fig.11 As shown, the folding portion may include a fourth folding portion 5, and the fourth folding portion 5 is distributed on the entire surface of the flexible bag 100, and a plurality of triangular areas are formed between the fourth folding portions 5, so that the flexible bag 100 has a plurality of different folding states. The fourth folding portion 5 includes a plurality of long strip grooves a, and each groove a can be used as a side of a triangular area, and the triangular area can be an isosceles triangle. Through these regularly distributed grooves a, the user can DIY the shape of the folding bag as needed. In the unfolded state, the flexible bag 100 can be in a one-piece state, and can be used as a temporary outdoor cushion, and the materials used for the overall bag shape are all a square piece, and there will be no waste of width, so the entire bag will be more economical.

[0110] In some possible implementations, see Fig.28a As shown, the folding portion includes a fifth folding portion 7, and the fifth folding portion 7 is distributed on the entire surface of the flexible package 100. Some of the fifth folding portions 7 are parallel to the horizontal support surface 400, and some of the fifth folding portions 7 are perpendicular to the horizontal support surface 400. A plurality of rectangular areas are formed between the fifth folding portions. The flexible package 100 has a plurality of different folding states. The flexible package 100 can be folded in half along the fifth folding portion 7 in the horizontal direction or the vertical direction. After folding, Fig.28b shown.

[0111] In some possible implementations, see Fig.28a As shown, the two ends of the bottom of the flexible bag body 100 also include fifth folds 7 that are at an angle with the horizontal support surface 400. The two ends of the bottom and the two ends of the waist of the flexible bag body 100 have matching fixing members 103. After the fixing members 103 at the bottom are connected with the fixing members 103 matching the waist, the bag body shape can be changed. For example, after the shape is changed, Fig.28c The fixing member 103 can be a buckle, a button, a Velcro, a strap, etc.

[0112] In some possible implementations, see Figure 3 and Fig.16 As shown, the filling layer 15 can be made of materials such as sponge 151, EVA, rubber-plastic insulation materials, silica aerogel felt, etc. In order to enhance the thermal insulation and keep dry, the filling layer 15 may include a sponge 151 and a composite sheet 152. The sponge 151 and the composite sheet 152 are bonded and fixed. The composite sheet 152 is any one or two of an aluminum foil sheet and an EVA sheet. In order to enhance the thermal insulation to a certain extent and at the same time save costs, sponges 151 of different multiples can be bonded to each other or sponges 151 can be bonded to other materials with low thermal conductivity. The filling layer 15 can be made of punching, wire cutting and other processes, which can make the self-inflating flexible package light, easy to compress, and small in size, and give the surface of the flexible package a texture of different styles. For example, see Fig.26 As shown, a plurality of through holes 154 can be provided on the filling layer 15 , and each through hole 154 needs to be hollowed out on the filling layer 154 . Accumulating a certain number of through holes 154 can greatly reduce the weight of the flexible package.

[0113] Most of the soft ice packs currently available on the market use thicker fabrics, usually wear-resistant and waterproof materials such as polyester cloth, Oxford cloth, etc., to protect the internal fillings and items that need to be kept warm, and the internal fillings are also made of relatively stiff and thick materials. Therefore, the common problem of most bags is that they have a certain weight. If food is filled inside, the weight will be greatly increased, which will cause inconvenience in carrying, and it will also take up a lot of space when not in use. Therefore, the lightweight and foldable self-inflating flexible bag 100 can solve this problem. Fig.17 and Fig.18 As shown, the filling layer 15 of the flexible bag 100 provided in the embodiment of the present application can be provided with a plurality of hole portions 153, and in the unfolded state, the outer fabric 16 forms an outer convex pattern at the hole. The hole portion 153 can be made by punching or wire cutting, so that the flexible bag 100 is light, easy to compress, small in size, and the surface of the flexible bag 100 has a texture of different styles. Compared with the manufacturing process on the market, the flexible bag 100 of the present application is lighter, easier to fold, smaller in size, and has heat preservation performance without increasing the cost.

[0114] Conventional ice packs on the market are relatively expensive and too professional. The flexible bag 100 provided in the embodiment of the present application is moderately priced, has heat preservation properties and is relatively light, and is suitable for daily shopping as well as for light outdoor enthusiasts, and has a wider market and audience.

[0115] The flexible package 100 may be provided with zippers 6, Velcro, buckles or other connecting structures on both sides of the opening to close or open the opening. The flexible package 100 may be provided with handles for easy single use, or it may be used in combination with other carriers.

[0116] like Figures 19a to 19d As shown, the embodiment of the present application also provides an ice pack, including: an ice pack shell 200 and the above-mentioned flexible package 100, and the flexible package 100 is detachably connected to the ice pack shell 200. The ice pack shell 200 is convenient for users to carry, and the ice pack shell 200 can protect the flexible package 100.

[0117] The ice pack shell 200 and the flexible pack body 100 are matched in any of the following ways:

[0118] In the first type of cooperation, Fig.19a As shown, the ice pack shell 200 has a accommodating cavity 201, and the flexible package body 100 can be accommodated in the accommodating cavity 201. At this time, the flexible package body 100 is used as an inner liner. When the ice pack needs to have heat preservation, the inner liner will be added. When it is only needed for ordinary storage, the ice pack shell 200 will be used. When the ice pack shell 200 is broken, only the ice pack shell 200 can be purchased, and when the inner liner is broken, only the inner liner can be purchased. In this way, it can be recycled, extending the service life of the product and reducing waste.

[0119] In the second cooperation mode, Fig.19b As shown, the ice pack shell 200 is provided with a first magnetic attraction component 202, and the flexible package 100 is provided with a second magnetic attraction component 101. The first magnetic attraction component 202 and the second magnetic attraction component 101 are magnetically attracted to each other, and the magnetic attraction matching method is simple in structure and easy to operate. The flexible package 100 can be placed inside the ice pack shell 200 or outside the ice pack shell 200, as long as the flexible package 100 does not fall off.

[0120] In the third type of cooperation, Fig.19c As shown, a first buckle 102 is provided on the ice pack shell 200, and a second buckle 203 is provided on the flexible enclosure 100, and the first buckle 102 and the second buckle 203 are fixed by snapping. In this embodiment, the ice pack shell 200 and the flexible enclosure 100 are fixed by snapping with a buckle structure, and the buckle structure has the advantages of high stability and reliability of the connection structure. The flexible enclosure 100 can be placed inside the ice pack shell 200 or outside the ice pack shell 200, as long as the flexible enclosure 100 does not fall off.

[0121] In the fourth type of cooperation, Fig.19dAs shown, Velcro 300 is provided on both the ice pack shell 200 and the flexible package 100, and the ice pack shell 200 and the flexible package 100 are fixed by Velcro. Velcro is convenient and easy to use. When the flexible package 100 is detached, it is only necessary to tear the Velcro apart. Velcro is easy to use and has the advantages of being economical and inexpensive, which further reduces the cost.
