Description

Technical Field

[0001] The present application relates to the technical field of ice packs, and in particular to a fresh-keeping ice pack. Background Art

[0002] Fresh-keeping ice bags are bags used to wrap and store food that needs to be stored at low temperatures. The bags contain ice cubes to keep the food fresh during transportation.

[0003] Traditional ice bags are mostly in the shape of bags. When refrigerating a single piece of food, the food cannot be wrapped. Usually, multiple ice bags are piled on the outside of the food, which still cannot achieve the effect of preserving food in all directions. For this reason, there are fresh-keeping ice bags on the market that connect multiple independent ice bags together. The food that needs to be transported at low temperatures is wrapped on the inside of the ice bag, which increases the contact area between the food and the ice bag, thereby increasing the refrigeration range and further improving the preservation effect.

[0004] During the use of the above-mentioned fresh-keeping ice bag, if the food is of irregular shape, it is difficult to achieve the effect of fresh-keeping, and the ice bag is in contact with the external hot air, so that water droplets condense on the outer surface of the ice bag, which will make other items damp. During the bumpy transportation of fresh-keeping, the food may slip out from both ends of the fresh-keeping bag, and the stability of the package is somewhat lacking. In view of this, the present application proposes a fresh-keeping ice bag. Utility Model Content

[0034] Example

[0035] like Figure 1-3 As shown, a fresh-keeping ice bag proposed in the present application includes a plurality of bag bodies 1, and the plurality of bag bodies 1 form a closed structure, and the closed structure is a ring-shaped closure, and food can be wrapped inside the plurality of bag bodies 1.

[0036] Two adjacent bag bodies 1 are connected by a connecting belt 2 for adjusting the storage space so that the closed space surrounded by a plurality of bag bodies 1 can be contracted or expanded, thereby accommodating foods of different sizes.

[0037] Among them, a containing bag 3 is arranged in a closed structure surrounded by several bag bodies 1, the containing bag 3 is connected to the inner wall of the bag body 1, and the containing bag 3 has a space expanding outwardly of the circumference, the containing bag 3 is a food packaging bag, and the containing bag 3 is made of pp material; the bottom end of the containing bag 3 is fixedly connected to a bottom pad 10 located on the inner side of the bottom end of several bag bodies 1, and the bottom pad 10 is made of sponge material, which can support and protect the bottom of the food.

[0038] The containing bag 3 is provided with a bag opening 4 , and a closing piece 5 is arranged at the edge of the bag opening 4 .

[0039] Specifically, the closing member 5 includes a plurality of connecting rings 51 fixedly connected to the edge of the bag opening 4, and a closing rope 52 is commonly passed through the plurality of connecting rings 51. Both ends of the closing rope 52 are connected to a first limiting piece 53 to prevent the closing rope 52 from detaching from the connecting ring 51. The closing rope 52 is a rubber elastic rope that can automatically complete elastic contraction to squeeze the ice cubes.

[0040] The bag body 1 includes an ice bag 11, the containing bag 3 is fixedly connected to the ice bag 11, and a protective layer 12 is fixedly connected to the outer arc surface of the ice bag 11. The protective layer 12 is made of sponge material and is used to absorb water droplets, buffer, and keep warm. A water injection port 7 is provided at the bottom end of the ice bag 11, and a rubber sealing cover 8 is inserted into the water injection port 7. A partition groove 9 is provided between two adjacent ice bags 11, and the connecting belt 2 is located in the partition groove 9. The connecting belt 2 has elastic force, and the size of the partition groove 9 changes according to the expansion and contraction of the connecting belt 2.

[0041] Furthermore, a tightening piece 6 is commonly provided on the outer side of several bag bodies 1, and the tightening piece 6 includes a connecting ring 61 fixedly connected to the outer surface of several protective layers 12, and a tightening rope 62 is commonly passed through the several connecting rings 61. Both ends of the tightening rope 62 are fixedly connected with a second limiting plate 63, which plays a role of limiting the two ends of the tightening rope 62.

[0042] The tightening rope 62 is an elastic rope, which is tightly wound and fixed on the outside of the plurality of bags 1 during transportation. When the ice cubes in the ice pack 11 slowly melt, the plurality of bags 1 are tightened toward the axis under the action of the elastic force of the tightening rope 62, so that the melted ice cubes continue to adhere to the outside of the food. This can extend the preservation time and allow the ice cubes to fully play their role.

[0043] The working principle of this embodiment is as follows: the present application forms an axially closed structure with a plurality of bag bodies 1, and ice cubes are arranged in a plurality of ice bags 11, which can be stably wrapped around the outside of the food that needs to be kept fresh. The food is placed in the receiving bag 3, and the closing rope 52 is tightened to close the bag mouth 4, so that the food that needs to be kept fresh is stored in the receiving bag 3, so that the food is fixed inside the receiving bag 3 and inside the plurality of bag bodies 1, and is in a stable fresh-keeping and refrigeration state during transportation, and will not slip out from the ends of the plurality of bag bodies 1 during the bumpy transportation.

[0044] By setting a protective layer 12 on the outside of the ice bag 11 and setting a bottom pad 10 on the bottom of the receiving bag 3, the protective layer 12 and the bottom pad 10 are both made of sponge material. The protective layer 12 can absorb the water droplets condensed on the outer surface of the ice bag 11 to prevent the water droplets from damaging the surrounding articles or food packaging boxes and avoid accumulating water and breeding bacteria. The protective layer 12 and the bottom pad 10 have a certain heat preservation effect, reduce the melting speed of ice cubes, and can also play a buffering and protective role for food during transportation.

[0045] During the process of transportation and preservation, the ice cubes will slowly melt. After the ice cubes melt, the ice bag will loosen (because the density of water is greater than the density of ice), which will reduce the preservation effect. The present application provides a tightening member 6 on the outside of several bag bodies 1, and tightens the tightening rope 62 during transportation. Because the tightening rope 62 has a certain elasticity, when the ice cubes in the ice bag 11 slowly melt, the several bag bodies 1 are tightened toward the axis under the action of the rebound force of the tightening rope 62, so that the melted ice cubes continue to stick to the outside of the food, thereby improving the preservation effect and extending the preservation time of the food.

[0046] The above-mentioned specific embodiments are merely preferred embodiments of the present application. Based on the technical solutions of the present application and the relevant inspirations of the above-mentioned embodiments, those skilled in the art may make various alternative improvements and combinations to the above-mentioned specific embodiments. The above-mentioned specific embodiments are merely explanations of the present application, and they are not limitations of the present application.
