Description
Technical Field
[0001] The utility model relates to the technical field of ice bags, and more specifically, to an ice bag. Background Art
[0002] During the distribution process of fresh food, drugs, reagents and other items, the distributed items need to be in a low-temperature environment to prevent phenomena such as corruption, deterioration, and invalidation due to excessive temperature during transportation. If the ambient temperature cannot be guaranteed during the distribution process, the quality of the distributed items will seriously decline after reaching the destination, which will further lead to a decrease in consumers' experience and evaluation of the products. With the development of the cold chain transportation industry and the improvement of people's living standards, ice bags, as the most commonly used refrigeration and preservation tools, are becoming more and more familiar and widely used by the public. However, in existing ordinary ice bags, frozen reagents are usually directly filled into a square bag body. Such a design is simple, but the heat dissipation is fast, the heat preservation effect is poor, and when the frozen reagents in the bag body melt, the ice bag is easily broken due to excessive extrusion by the transported items. Content of the Utility Model

[0005] The utility model divides the ice bag main body into a frozen reagent pipeline for injecting frozen reagents and an air chamber for filling air through heat-sealing lines. Among them, the space occupied by the frozen reagents in the frozen reagent pipeline is small, and the weight is lighter than that of ordinary ice bags. Moreover, due to the curved design of the frozen reagent channel, the contact area of the frozen area is larger, which is beneficial to improving the refrigeration effect; and the air layer can provide a certain supporting force for the entire ice bag main body after injecting air, which can prevent the frozen reagent pipeline from being broken due to excessive extrusion by the transported items after the frozen reagents melt, and can also play a certain buffering and protective role for the items to be transported, and can reduce the collision damage of the transported items during transportation. In addition, due to the slow heat transfer speed of air, the air layer can provide a certain heat preservation effect, which can avoid the rapid melting of the frozen reagents in the frozen reagent channel, thereby prolonging the heat preservation time of the ice bag and improving the heat preservation effect.

[0016] (1) The setting of the cryogenic reagent channel of the present utility model makes the space occupied by the cryogenic reagent smaller, the weight is lighter than that of a common ice bag, and because the cryogenic reagent channel is designed in a curved shape, the contact area of the refrigerated area is larger, which is beneficial to improving the refrigeration effect;

[0030] The technical solutions of the present utility model will be further specifically described below through specific embodiments in conjunction with the accompanying drawings:
[0031] Embodiment 1
[0032] This embodiment provides an ice pack. As Figure 1 and Figure 2 shown, the ice pack in this embodiment includes an ice pack body 1. The ice pack body 1 includes a first face mask 2 and a second face mask 3. Both the first face mask 2 and the second face mask 3 are plastic films. Specifically, the first face mask 2 can be a PE plastic film, a PO plastic film, a PP plastic film, an OPP plastic film, a PPE plastic film, an EVA plastic film, or a PVC plastic film. The second face mask 3 can be a PE plastic film, a PO plastic film, a PP plastic film, an OPP plastic film, a PPE plastic film, an EVA plastic film, or a PVC plastic film. In this embodiment, both the first face mask 2 and the second face mask 3 are PVC plastic films.
[0033] In this embodiment, both the first face mask 2 and the second face mask 3 are square. The four peripheral edges of the first face mask 2 and the four peripheral edges of the second face mask 3 are thermally pressed and fixedly connected, so that the four peripheral edges of the first face mask 2 and the four peripheral edges of the second face mask 3 are hermetically bonded together. In this embodiment, the abutting edges of the first face mask 2 and the second face mask 3 form the connecting edge 11 of the ice pack body 1.
[0034] As Figure 1As shown, a heat-sealing line 4 formed by hot pressing is provided on the ice bag body 1. The heat-sealing line 4 divides the space between the first mask 2 and the second mask 3 into a freezing reagent channel 5 and an air chamber 6. The freezing reagent channel 5 is used for injecting a freezing reagent, and the freezing reagent can be water or a superabsorbent resin. The superabsorbent resin can be selected from sodium carboxymethyl cellulose, polyvinyl alcohol, or sodium polyacrylate. The air chamber 6 is used for filling air.
[0035] Among them, the freezing reagent channel 5 is curved. Specifically, the freezing reagent channel 5 includes a plurality of first channels 51. The plurality of first channels 51 are arranged at intervals along the transverse or longitudinal direction of the ice bag body 1. The adjacent first channels 51 are connected end to end through a second channel 52. Such a setting can increase the path length of the freezing reagent channel 5. As a preferred technical solution, the first channel 51 can be set to be linear, broken line-shaped, or wavy, and the second channel 52 can be set to be arc-shaped. In this embodiment, the first channel 51 is set to be linear, and the second channel 52 is set to be semi-circular arc-shaped.
[0036] An inlet 7 communicating with the freezing reagent channel 5 is provided on the ice bag body 1. In this embodiment, the inlet 7 is arranged at the edge where the first mask 2 and the second mask 3 are attached, that is, the edge positions of the first mask 2 and the second mask 3 where the inlet 7 is arranged are not hermetically attached. The two sides of the freezing reagent channel 5 are two heat-sealing lines 4. One port of the freezing reagent channel 5 is communicated with the inlet 7, and the other port of the freezing reagent channel 5 is sealed by hot pressing.
[0037] When the ice bag is in use, the freezing reagent is injected into the freezing reagent pipeline 5 through the inlet 7. The injection amount of the freezing reagent in the freezing reagent channel 5 is 1 / 2 to 2 / 3 of the capacity of the freezing reagent channel. Such a design can prevent the too little addition of the freezing reagent in the freezing reagent channel 5 from affecting the cooling effect, and at the same time can avoid damage to the freezing reagent channel 5 caused by thermal expansion and contraction. The injection amount of the freezing reagent in the freezing reagent channel 5 can also be adjusted according to the type of the freezing reagent. In this embodiment, the injection amount of the freezing reagent in the freezing reagent channel 5 is 2 / 3 of the capacity of the freezing reagent channel. After the required amount of the freezing reagent is injected into the freezing reagent pipeline 5, the inlet 7 is sealed by hot pressing. In this embodiment, a freezing reagent channel 5 dedicated to injecting the freezing reagent is provided on the ice bag body 1, so that the space occupied by the freezing reagent is smaller, and the weight is lighter than that of a common ice bag. Moreover, due to the curved design of the freezing reagent channel 5, the contact area of the freezing area is larger, which is beneficial to improving the refrigeration effect.
[0038] An air chamber 6 is formed between the edges where the first mask 2 and the second mask 3 are joined and the heat-sealing line 4. An air inlet 8 communicating with the air chamber 6 is provided on the ice bag body 1. In this embodiment, the air inlet 8 is arranged at the edge where the first mask 2 and the second mask 3 are joined, that is, the edges of the first mask 2 and the second mask 3 where the air inlet 8 is provided are not hermetically joined. After air is filled into the air chamber 6 through the air inlet 8, the air inlet 8 is sealed by hot pressing.
[0039] In this embodiment, after the air layer 6 is filled with air, it can provide a certain supporting force for the entire ice bag body 1, which can prevent the freezing reagent pipeline 5 from being excessively squeezed and broken by the transported items after the freezing reagent melts, and can also play a certain buffering and protective role for the transported items, and can reduce the collision damage of the transported items during transportation. In addition, due to the slow heat transfer speed of air, the air layer 6 can provide a certain heat preservation effect, which can prevent the rapid melting of the freezing reagent in the freezing reagent channel 5, thereby prolonging the heat preservation time of the ice bag and improving the heat preservation effect.
[0040] The ice bag of the present utility model can be used as a disposable product, and can also be frozen and thawed repeatedly without affecting its own freezing effect and without being damaged due to repeated freezing and thawing. Specifically, the first mask 2 and the second mask 3 can be made of plastic materials with different anti-wear degrees according to the number of times of repeated use required. Compared with the traditional ordinary ice bag, the ice bag body 1 of the present utility model is divided into a freezing reagent pipeline 5 for injecting freezing reagent and an air chamber 6 for filling air. Among them, the space occupied by the freezing reagent in the freezing reagent pipeline 5 is smaller, and the weight is lighter than that of the ordinary ice bag. And because the freezing reagent channel 5 is designed in a curved shape, the contact area of the freezing area is larger, which is beneficial to improving the refrigeration effect. After the air layer 6 is filled with air, it can provide a certain supporting force for the entire ice bag body 1, which can prevent the freezing reagent pipeline 5 from being excessively squeezed and broken by the transported items after the freezing reagent melts, and can also play a certain buffering and protective role for the transported items, and can reduce the collision damage of the transported items during transportation. In addition, due to the slow heat transfer speed of air, the air layer 6 can provide a certain heat preservation effect, which can prevent the rapid melting of the freezing reagent in the freezing reagent channel 5, thereby prolonging the heat preservation time of the ice bag and improving the heat preservation effect.
[0041] Embodiment 2
[0042] This embodiment provides an ice bag. The difference between this embodiment and Embodiment 1 is that: as Figure 3As shown, the ice bag of this embodiment includes a plurality of ice bag bodies 1. Specifically, the ice bag includes a total of 6 ice bag bodies 1, and the 6 ice bag bodies 1 are divided into 3 ice bag bodies 1 of different size specifications. The 6 ice bag bodies 1 are arranged and placed according to the shape of the unfolded drawing of a square box body, and the connecting edges 11 of adjacent ice bag bodies 1 are heat-pressed and connected. After connection, the ice bag bodies 1 can be directly placed into a fresh food carton or a foam box. By bending the connecting edges 11 of the ice bag bodies 1, a box body structure can be formed, and thus a complete and three-dimensional low-temperature environment can be formed, which is convenient and fast to use. Items such as fresh food, medicines, and reagents can be directly loaded, such as fruits, meats, active protein drugs, etc. Such a design can completely wrap the items to be transported within the box body space formed by the ice bag bodies 1, and thus can greatly improve the heat preservation and freshness preservation effects.
[0043] Embodiment 3
[0044] This embodiment provides an ice bag. The difference between this embodiment and Embodiment 1 is that: as Figure 4 ( Figure 4 only showing the overall shape of the ice bag) shown, in this embodiment, the two opposite connecting edges 11 of the ice bag body 1 are connected end to end to form a columnar structure. This columnar-structured ice bag is suitable for transporting fresh items with a columnar structure in appearance, such as fresh flowers. By using the ice bag in this embodiment, the fresh flowers transported over a long distance can ensure higher quality in a low-temperature environment and extend the freshness preservation period of the flowers.
[0045] Embodiment 4
[0046] This embodiment provides an ice bag. The difference between this embodiment and Embodiment 1 is that: as Figure 5 ( Figure 5 only showing the overall shape of the ice bag) shown, in this embodiment, the two opposite connecting edges 11 of the ice bag body 1 are connected end to end, and at the same time, the bottom edge 11 of the formed columnar ice bag is connected. Finally, an ice bag with a pocket structure is formed. This pocket-structured ice bag can directly hold the items to be transported, such as medicines or reagents that need to be transported at low temperature. In addition, the top opening of the ice bag can also be sealed at the edge with tape as needed, and a completely enclosed low-temperature environment can be formed, and thus the low-temperature environment required for transporting items can be effectively guaranteed.
[0047] Embodiment 5
[0048] This embodiment provides an ice bag. The difference between this embodiment and Embodiment 1 is that: as Figures 6 - 8As shown in the figure, on the two opposite connecting edges 11 of the ice bag body 1, there are respectively a plug hole 91 and a plug-in part 92. The plug-in part 92 can be plugged into the plug hole 91. Through the arrangement of the plug hole 91 and the plug-in part 92, multiple ice bags can be connected together, and thus ice bags of different sizes and specifications can be formed, which can be applied to different application scenarios. To ensure sufficient design positions for the plug hole 91 and the plug-in part 92, the width of the connecting edge 11 of the ice bag body 1 is at least 0.5 cm to 1.0 cm. In this embodiment, the width of the connecting edge 11 of the ice bag body 1 is at least 0.8 cm.
[0049] Specifically, the plug hole 91 is set as a strip hole. The plug-in part 92 includes a connecting part 921 and an elastic plugging head 922. In this embodiment, the plugging head 922 is set as semi-elliptical. One end of the connecting part 921 is fixedly connected to the connecting edge 11, and the other end is fixedly connected to the straight edge of the plugging head 922. The connecting part 921 and the plugging head 922 can be designed as an integrally formed structure.
[0050] In this embodiment, the plug-in part 92 is integrally in a sheet structure. The length of the plug hole 91 is greater than the width of the connecting part 921 and less than the maximum width of the plugging head 922. In this embodiment, the maximum width of the plugging head 922 is the length of the straight edge of the plugging head 922. Since the plugging head 922 has elasticity, the plugging head 922 of one ice bag can be plugged into the plug hole 91 of another ice bag by an external force. Since the length of the plug hole 91 is less than the maximum width of the plugging head 922, the plugging head 922 can be limited in the plug hole 91 without the action of an external force, and thus two ice bags can be firmly connected together.
[0051] As a preferred technical solution, corresponding plug holes 91 and plug-in parts 92 can be respectively arranged on the four connecting edges 11 of the ice bag body 1, so that multiple ice bags can be connected both horizontally and vertically.
[0052] As a preferred technical solution, multiple plug holes 91 are arranged at intervals on the connecting edge 11 of the ice bag body 1. Correspondingly, multiple plug-in parts 92 are also arranged at intervals on the connecting edge 11 of the ice bag body 1. The arrangement of multiple groups of plug holes 91 and plug-in parts 92 can greatly improve the stability of the connection between ice bags.
[0053] In this embodiment, the arrangement of the plug hole 91 and the plug-in part 92 can not only connect multiple ice bags together, but also when in use, the plug-in part 92 and the plug hole 91 on the two opposite connecting edges 11 of the same ice bag can be plugged together to form a columnar ice bag, which is suitable for transporting fresh products with a columnar structure appearance, such as fresh flowers and the like.
[0054] Obviously, the above embodiments of the present utility model are merely examples for clearly illustrating the present utility model, rather than limitations on the implementation manners of the present utility model. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the claims of the present utility model.
